https://git.kernel.org/…/ke…/... sure some of you are working on the patches already, if you are then lets connect cause, I am an ardent researcher for the same as of now.
So here it goes:
As soon as kernel page table isolation(KPTI) bug will be out of embargo, Whatsapp and FB will be flooded with over-night kernel "shikhuritee" experts who will share shitty advices non-stop.
1. The bug under embargo is a side channel attack, which exploits the fact that Intel chips come with speculative execution without proper isolation between user pages and kernel pages. Therefore, with careful scheduling and timing attack will reveal some information from kernel pages, while the code is running in user mode.
In easy terms, if you have a VPS, another person with VPS on same physical server may read memory being used by your VPS, which will result in unwanted data leakage. To make the matter worse, a malicious JS from innocent looking webpage might be (might be, because JS does not provide language constructs for such fine grained control; atleast none that I know as of now) able to read kernel pages, and pawn you real hard, real bad.
2. The bug comes from too much reliance on Tomasulo's algorithm for out-of-order instruction scheduling. It is not yet clear whether the bug can be fixed with a microcode update (and if not, Intel has to fix this in silicon itself). As far as I can dig, there is nothing that hints that this bug is fixable in microcode, which makes the matter much worse. Also according to my understanding a microcode update will be too trivial to fix this kind of a hardware bug.
3. A software-only remedy is possible, and that is being implemented by all major OSs (including our lovely Linux) in kernel space. The patch forces Translation Lookaside Buffer to flush if a context switch happens during a syscall (this is what I understand as of now). The benchmarks are suggesting that slowdown will be somewhere between 5%(best case)-30%(worst case).
4. Regarding point 3, syscalls don't matter much. Only thing that matters is how many times syscalls are called. For example, if you are using read() or write() on 8MB buffers, you won't have too much slowdown; but if you are calling same syscalls once per byte, a heavy performance penalty is guaranteed. All processes are which are I/O heavy are going to suffer (hostings and databases are two common examples).
5. The patch can be disabled in Linux by passing argument to kernel during boot; however it is not advised for pretty much obvious reasons.
6. For gamers: this is not going to affect games (because those are not I/O heavy)
Meltdown: "Meltdown" targeted on desktop chips can read kernel memory from L1D cache, Intel is only affected with this variant. Works on only Intel.
Spectre: Spectre is a hardware vulnerability with implementations of branch prediction that affects modern microprocessors with speculative execution, by allowing malicious processes access to the contents of other programs mapped memory. Works on all chips including Intel/ARM/AMD.

Recently had an interview with a company. At some point an SELinux question came up and while I didn't provide the best answer ever (I'm hardly familiar with SELinux and mentioned that as well beforehand so they knew), it was technically correct and the reaction of the interviewers was funny.
TI (technical interviewer): say your php script isn't executed and after a while you find out that SELinux is blocking php script execution, how can you fix that?
Me: setenforce 0...? (essentially disabling SELinux at all)
TI: disabling it entirely for getting php execution to work?! That doesn't sound like a good solu...
HRI (HR (non technical) interviewer, also present): *turns to TI* - but, would it solve the problem?
TI: 😐 well, yes, but... That's a bad thing to do so I wouldn't count is corre..
HRI: *still aiming towards TI* but you simply asked him for a way to solve the php execution issue, would his answer work? Regardless of whether it's the best or worst solution, would it be a solution which works?
TI: well... yes...
HRI: then he answered correctly I'd say, next!
(yes, I'm aware that my answer wasn't good as for security at all but it would have solved that problem which is what was asked)18 -

So... I just remembered a story that's perfect for devrant.
My brother got into engineering in university, and during the second semester they had their introductory class to programming. They had weekly homeworks that the lecturer would check and give grades accordingly.
The factors that could influence the grading were: execution (meaning that the code would excecute as intended), efficiency and readabilty. The weeks passed and everyone was doing well, getting fairly good grades. Everyone was happy.
Until one day a random guy we'll call bob got the worst grade possible. Bob wasn't a bad student. He had over-the-average grades in all the weekly homeworks and even impressed the professor in some. Naturally, he was baffled when he saw his grade on the google spreadsheet. He was pretty sure his code ran well. He always tested it on different machines and OSs. So, at the end of the class, he went straight to the helper of the class, in a pretty imperative manner, to demand to know how the fuck he got that grade. It's impossible he got excecution, efficiency and readabilty, wrong. All three wrong? Impossible. Even the stupidiest kid in the class had some points on readabilty.
"Oh, so you are Bob. Huh?" said the helper in a laid-back attitude. "Come with me. Prof. X is waiting for you in his office."
This got Bob even more confused. As they approached the office, the courage he had in a first moment banished and gave way for nervousness and fear.
The helper nocks the door. "Prof., Bobs here"
As soon as Bob sits in the chair in front of Prof. X's, he knew something bad was coming.
"In all these years of teaching..." said Prof. X hesitantly. "In all these years of teaching I have not come even close to see something similar to what you've done. You should be ashamed of yourself." Needless to say, Bob was panicked.
"In all these years I have not seen such blatant mockery!" added the professor. "HOW THE FUCK DID YOU EVEN DARE TO SEND A HOMEWORK WITH SUCH VARIABLE NAMING" That's when Bob realised the huge mistake he made. "NEVER IN ALL THESE YEARS I HAVE SEEN SOMEONE NAME HIS VARIABLES *opens the file on his desktop *: PENIS, SHIT, FUCKSHIT, GAYFUCKING<insert Prof. X's name>MAN, GOATSE, VAGINAVAR, CUMFUNCTION, [...]" The list of obcenities went on and on. In each word, the professor hit the table harder than the last time.
Turns out Bob felt so in comfort with the ease of the course he decided to spice things up by using "funny naming conventions" while coding, and then tidying everything up before uploading the homework. This week he forgot, and fucked it big time.
So remember folks, always check your code before committing/giving it in/production. And always adhere to naming conventions.9 -
New JS arrow functions:
⇶ (“the gun rack”) – executes three times
↝ (“wiggly boi”) – finds the least efficient solution possible
⟳ (“the self-monch”) – executes forever
⍆ (“🤷”) – adds random side effects
⍅ (“the total and complete s**t”) – undoes the only useful and expected part of its execution
Absolutely hilarious 😆

A group of Security researchers has officially fucked hardware-level Intel botnet officially branded as "Intel Management Engine" they did so by gathering it all the autism they were able to get from StackOverflow mods... though they officially call it a Buffer Overflow.
On Wednesday, in a presentation at Black Hat Europe, Positive Technologies security researchers Mark Ermolov and Maxim Goryachy plan to explain the firmware flaws they found in Intel Management Engine 11, along with a warning that vendor patches for the vulnerability may not be enough.
Two weeks ago, the pair received thanks from Intel for working with the company to disclose the bugs responsibility. At the time, Chipzilla published 10 vulnerability notices affecting its Management Engine (ME), Server Platform Services (SPS), and Trusted Execution Engine (TXE).
The Intel Management Engine, which resides in the Platform Controller Hub, is a coprocessor that powers the company's vPro administrative features across a variety of chip families. It has its own OS, MINIX 3, a Unix-like operating system that runs at a level below the kernel of the device's main operating system.
It's a computer designed to monitor your computer. In that position, it has access to most of the processes and data on the main CPU. For admins, it can be useful for managing fleets of PCs; it's equally appealing to hackers for what Positive Technologies has dubbed "God mode."
The flaws cited by Intel could let an attacker run arbitrary code on affected hardware that wouldn't be visible to the user or the main operating system. Fears of such an attack led Chipzilla to implement an off switch, to comply with the NSA-developed IT security program called HAP.
But having identified this switch earlier this year, Ermolov and Goryachy contend it fails to protect against the bugs identified in three of the ten disclosures: CVE-2017-5705, CVE-2017-5706, and CVE-2017-5707.
The duo say they found a locally exploitable stack buffer overflow that allows the execution of unsigned code on any device with Intel ME 11, even if the device is turned off or protected by security software.

1) get an idea for a cool app
2) evaluate feasibility and execution
3) ensure accessible data streams and APIs
4) get excited and realize the idea is doable
5) see someone has done that exact thing and it's already published on the Appstore :/10 -
At the moment I'm trying to optimize a slow old MySQL query from a project I made several years ago. The execution time is in excess of 55 seconds. Not good :(
After about an hour of experimenting I finally set a good index and reduced the time to < 3 seconds.
Chuffed :)

"Errors? Won't happen to me!"
One of my first jobs was to finish and maintain a program, that was made by a guy who had a real genius image among others. Years later, people said "oh him, that smart guy."
I never met him, but that's what i heard.
However, he was not only smart, but it seems he was also very confident. That's what i deduct from his code.
He didn't use catch-blocks. They were all empty. Not even logged.
If errors appeared , it was not possible to see what happened and where and why. The program would continue it's execution and if following steps could not work, because there had been an unnoticed exception, it would just throw another unnoticed exception and at some point, end in an undefined state.5 -
#2 Worst thing I've seen a co-worker do?
Back before we utilized stored procedures (and had an official/credentialed DBA), we used embedded/in-line SQL to fetch data from the database.
var sql = @"Select
FieldsToSelect
From
dbo.Whatever
Where
Id = @ID"
In attempts to fix database performance issues, a developer, T, started putting all the SQL on one line of code (some sql was formatted on 10+ lines to make it readable and easily copy+paste-able with SSMS)
var sql = "Select ... From...Where...etc";
His justification was putting all the SQL on one line make the code run faster.
T: "Fewer lines of code runs faster, everyone knows that."
Mgmt bought it.
This process took him a few months to complete.
When none of the effort proved to increase performance, T blamed the in-house developed ORM we were using (I wrote it, it was a simple wrapper around ADO.Net with extension methods for creating/setting parameters)
T: "Adding extra layers causes performance problems, everyone knows that."
Mgmt bought it again.
Removing the ORM, again took several months to complete.
By this time, we hired a real DBA and his focus was removing all the in-line SQL to use stored procedures, creating optimization plans, etc (stuff a real DBA does).
In the planning meetings (I was not apart of), T was selected to lead because of his coding optimization skills.
DBA: "I've been reviewing the execution plans, are all the SQL code on one line? What a mess. That has to be worst thing I ever saw."
T: "Yes, the previous developer, PaperTrail, is incompetent. If the code was written correctly the first time using stored procedures, or even formatted so people could read it, we wouldn't have all these performance problems."
DBA didn't know me (yet) and I didn't know about T's shenanigans (aka = lies) until nearly all the database perf issues were resolved and T received a recognition award for all his hard work (which also equaled a nice raise).7 -

The gift that keeps on giving... the Custom CMS Of Doom™
I've finally seen enough evidence why PHP has such a bad reputation to the point where even recruiters recommended me to remove my years of PHP experience from the CV.
The completely custom CMS written by company <redacted>'s CEO and his slaves features the following:
- Open for SQL injection attacks
- Remote shell command execution through URL query params
- Page-specific strings in most core PHP files
- Constructors containing hundreds of lines of code (mostly used to initialize the hundreds of properties
- Class methods containing more than 1000 lines of code
- Completely free of namespaces or package managers (uber elite programmers use only the root namespace)
- Random includes in any place imaginable
- Methods containing 1 line: the include of the file which contains the method body
- SQL queries in literally every source file
- The entrypoint script is in the webroot folder where all the code resides
- Access to sensitive folders is "restricted" by robots.txt 🤣🤣🤣🤣
- The CMS has its own crawler which runs by CRONjob and requests ALL HTML links (yes, full content, including videos!) to fill a database of keywords (I found out because the server traffic was >500 GB/month for this small website)
- Hundreds of config settings are literally defined by "define(...)"
- LESS is transpiled into CSS by PHP on requests
- .......
I could go on, but yes, I've seen it all now.12 -
The bossman asked if our signup service sends an automated email after we successfully process someone's payment or when we promote them to full customer.
That sounds like a simple query, yeah?
Well.
Here's some background:
We have four applications; one in React, three in Rails. I'll replace their names to retain some anonymity.
1) "IceSkate" is the React app, and it's a glorified signup form. (I wrote this one.)
2) "Bogan" is the main application, and is API-only; its frontend has been long since deprecated by the following two:
3) "Bum" is a fork of "Bogan" that has long since diverged. It now contains admin-only tools.
4) "Kulkuri" is also a fork of "Bogan" that has long since diverged. It now contains tools specifically for customers, which they can access.
All but IceSkate (obv) share a database.
Here's how signups happen:
Signups come in from IceSkate, which hits a backend API on Bogan. Bogan writes the data to the database, charges the card immediately, and leaves the signup for moderation.
And here's how promotion from signup to customer happens:
Bum has a view allowing admins to validate, modify, and "promote" a signup to a full customer. Upon successful promotion, Bum calls "ServerWrap", a module which calls actions on the other applications; in this case: Bogan.
Bogan routes execution through three separate models before calling "ServerWrap" again, this time calling KulKuri.
Finally, KulKuri actually creates the customer!
After KulKuri finishes creating the customer, execution resumes on Bogan, which then returns, causing execution to resume on Bum. Bum then runs through several other models, references the newly-created customer object (as all three share a database), and ... updates the customer with its current data, and then updates the signup object. After all of this, it finally shows the admin the "new customer" view.
It took me 25 minutes to follow the chain of calls, and I still don't know quite what's going on. I have no idea if any of it sends an email or not -- I didn't see any signs of this, but I very easily could have overlooked something.
So, to answer bossman's question... I asked the accounting people if they send the email manually. If they don't, it's automatic, which means I missed something and get to burrow through that mess all over again!
I really hope I missed something; otherwise I need to figure out how and where (and when!) to send the email...
just...

Most satisfying bug I've fixed?
Fixed a n+1 issue with a web service retrieving price information. I initially wrote the service, but it was taken over by a couple of 'world class' monday-morning-quarterbacks.
The "Worst code I've ever seen" ... "I can't believe this crap compiles" types that never met anyone else's code that was any good.
After a few months (yes months) and heavy refactoring, the service still returned price information for a product. Pass the service a list of product numbers, service returns the price, availability, etc, that was it.
After a very proud and boisterous deployment, over the next couple of days the service seemed to get slower and slower. DBAs started to complain that the service was causing unusually high wait times, locks, and CPU spikes causing problems for other applications. The usual finger pointing began which ended up with "If PaperTrail had written the service 'correctly' the first time, we wouldn't be in this mess."
Only mattered that I initially wrote the service and no one seemed to care about the two geniuses that took months changing the code.
The dev manager was able to justify a complete re-write of the service using 'proper development methodologies' including budgeting devs, DBAs, server resources, etc..etc. with a projected year+ completion date.
My 'BS Meter' goes off, so I open up the code, maybe 5 minutes...tada...found it. The corresponding stored procedure accepts a list of product numbers and a price type (1=Retail, 2=Dealer, and so on). If you pass 0, the stored procedure returns all the prices.
Code basically looked like this..
public List<Prices> GetPrices(List<Product> products, int priceTypeId)
{
foreach (var item in products)
{
List<int> productIdsParameter = new List<int>();
productIdsParameter.Add(item.ProductID);
List<Price> prices = dataProvider.GetPrices(productIdsParameter, 0);
foreach (var price in prices)
{
if (price.PriceTypeID == priceTypeId)
{
prices = dataProvider.GetPrices(productIdsParameter, price.PriceTypeID);
return prices;
}
* Omitting the other 'WTF?' code to handle the zero price type
}
}
}
I removed the double stored procedure call, updated the method signature to only accept the list of product numbers (which it was before the 'major refactor'), deployed the service to dev (the issue was reproducible in our dev environment) and had the DBA monitor.
The two devs and the manager are grumbling and mocking the changes (they never looked, they assumed I wrote some threading monstrosity) then the DBA walks up..
DBA: "We're good. You hit the database pretty hard and the CPU never moved. Execution plans, locks, all good to go."
<dba starts to walk away>
DevMgr: "No fucking way! Putting that code in a thread wouldn't have fix it"
Me: "Um, I didn't use threads"
Dev1: "You had to. There was no way you made that code run faster without threads"
Dev2: "It runs fine in dev, but there is no way that level of threading will work in production with thousands of requests. I've got unit tests that prove our design is perfect."
Me: "I looked at what the code was doing and removed what it shouldn't be doing. That's it."
DBA: "If the database is happy with the changes, I'm happy. Good job. Get that service deployed tomorrow and lets move on"
Me: "You'll remove the recommendation for a complete re-write of the service?"
DevMgr: "Hell no! The re-write moves forward. This, whatever you did, changes nothing."
DBA: "Hell yes it does!! I've got too much on my plate already to play babysitter with you assholes. I'm done and no one on my team will waste any more time on this. Am I clear?"
Seeing the dev manager face turn red and the other two devs look completely dumbfounded was the most satisfying bug I've fixed.5 -
*Opens some Computerphile video on YouTube in Chrome Canary*
CPU > hey ho dude, wait a minute..! I can't process all of this in realtime!!! >_<
Alright.. I think I've still got a copy of all their videos sitting somewhere in the file server.. perhaps I could use that instead.
*Opens said video from the file server in SMPlayer*
CPU > aah, thanks man. Now I can allocate 15-ish % of my resources to that and give you a good watching experience.
Web browsers are really great for being the most general-purpose document viewers, application execution environments (remote code execution engines as someone here called it), and overall be one of the most versatile programs on any PC's standard software suite.
But that comes at a price.. performance. And definitely when it comes to featureful fucking WordPress shitsites (shites?), bloated YouTube, Google, Facebook, and all that fucking garbage.. I fucking hate web browsers and this "Web 2.0" that people keep on talking about. Your boatload of JavaScript frameworks just to ease your own fucking development has a real impact when it happens on dozens of tabs, you know.
Besides, can't those framework creators just make it into a "compiler" * of sorts? So that front-end devs can flail their dicks in an shit-infested environment full of libraries and frameworks all they want, but the framework can convert it into plain JS code that the web server can then serve. Or better yet, the JavaScript standard could be improved to actually be usable on its own!
Look, I'm not a front-end dev. Heck, I'm not even a dev to begin with. But what I do know is that efficiency matters, especially at large scale. Web browsers being so overgeneralized and web devs adding a boatload of fucking libraries or frameworks or whatever, it adds up, both to the CPU's and my own temper.

I guess my best AHHA moment was back when I learned that good code is simple code.
When I started out I wanted to prove myself by showing of how good of a programmer I was(and which I retrospectively wasn't) , which basically meant to use every high level concept I was aware of whenever possible. Multi threading where linear execution would have been totally okay, polymorphism with x meta classes where a switch would have been enough, all that shit.
It wasn't until I had to guide the first person through that mess of useless ego stroking that I found out how much time and money I wasted by not going with the easiest approach that solves the problem.
Took me some time to fully lay off that attitude but it surely was one of the most influential moments of my career.6 -

"build an app without writing code"
Great, if you want to build a prototype and then try to find a technical co-founder who can actually build something.
Otherwise, none of us need another shitty cookie-cutter app.
There is a 0% chance you can build anything that will scale without writing some code. Your best case scenario is you sell it to some sucker who doesn't understand that what they are buying is garbage.
I give those folks 3 options...
1. Find a technical co-founder
2. Learn to build software
3. Fuck off

Of course, that won't stop the thousands of business grads each year from trying and saying...

Okay, story time.
Back during 2016, I decided to do a little experiment to test the viability of multithreading in a JavaScript server stack, and I'm not talking about the Node.js way of queuing I/O on background threads, or about WebWorkers that box and convert your arguments to JSON and back during a simple call across two JS contexts.
I'm talking about JavaScript code running concurrently on all cores. I'm talking about replacing the god-awful single-threaded event loop of ECMAScript – the biggest bottleneck in software history – with an honest-to-god, lock-free thread-pool scheduler that executes JS code in parallel, on all cores.
I'm talking about concurrent access to shared mutable state – a big, rightfully-hated mess when done badly – in JavaScript.
This rant is about the many mistakes I made at the time, specifically the biggest – but not the first – of which: publishing some preliminary results very early on.
Every time I showed my work to a JavaScript developer, I'd get negative feedback. Like, unjustified hatred and immediate denial, or outright rejection of the entire concept. Some were even adamantly trying to discourage me from this project.
So I posted a sarcastic question to the Software Engineering Stack Exchange, which was originally worded differently to reflect my frustration, but was later edited by mods to be more serious.
You can see the responses for yourself here: https://goo.gl/poHKpK
Most of the serious answers were along the lines of "multithreading is hard". The top voted response started with this statement: "1) Multithreading is extremely hard, and unfortunately the way you've presented this idea so far implies you're severely underestimating how hard it is."
While I'll admit that my presentation was initially lacking, I later made an entire page to explain the synchronisation mechanism in place, and you can read more about it here, if you're interested:
http://nexusjs.com/architecture/
But what really shocked me was that I had never understood the mindset that all the naysayers adopted until I read that response.
Because the bottom-line of that entire response is an argument: an argument against change.
The average JavaScript developer doesn't want a multithreaded server platform for JavaScript because it means a change of the status quo.
And this is exactly why I started this project. I wanted a highly performant JavaScript platform for servers that's more suitable for real-time applications like transcoding, video streaming, and machine learning.
Nexus does not and will not hold your hand. It will not repeat Node's mistakes and give you nice ways to shoot yourself in the foot later, like `process.on('uncaughtException', ...)` for a catch-all global error handling solution.
No, an uncaught exception will be dealt with like any other self-respecting language: by not ignoring the problem and pretending it doesn't exist. If you write bad code, your program will crash, and you can't rectify a bug in your code by ignoring its presence entirely and using duct tape to scrape something together.
Back on the topic of multithreading, though. Multithreading is known to be hard, that's true. But how do you deal with a difficult solution? You simplify it and break it down, not just disregard it completely; because multithreading has its great advantages, too.
Like, how about we talk performance?
How about distributed algorithms that don't waste 40% of their computing power on agent communication and pointless overhead (like the serialisation/deserialisation of messages across the execution boundary for every single call)?
How about vertical scaling without forking the entire address space (and thus multiplying your application's memory consumption by the number of cores you wish to use)?
How about utilising logical CPUs to the fullest extent, and allowing them to execute JavaScript? Something that isn't even possible with the current model implemented by Node?
Some will say that the performance gains aren't worth the risk. That the possibility of race conditions and deadlocks aren't worth it.
That's the point of cooperative multithreading. It is a way to smartly work around these issues.
If you use promises, they will execute in parallel, to the best of the scheduler's abilities, and if you chain them then they will run consecutively as planned according to their dependency graph.
If your code doesn't access global variables or shared closure variables, or your promises only deal with their provided inputs without side-effects, then no contention will *ever* occur.
If you only read and never modify globals, no contention will ever occur.
Are you seeing the same trend I'm seeing?
Good JavaScript programming practices miraculously coincide with the best practices of thread-safety.
When someone says we shouldn't use multithreading because it's hard, do you know what I like to say to that?
"To multithread, you need a pair."18 -
Here is a preview of my Python devRant client
The client supports both CLI and GUI modes.
This is the CLI mode using the rant command.
CLI mode currently supports dynamic importing of custom commands (and creating your own command is documented already too).
If you do not like my rant command? Download or make another one.
Also, the command execution, import, and registration process all send events to the application object. This is in preparation for allowing mods!
Unfortunately, emojis are technically 2-width, so they totally fuck up the box I draw around the rant. Lots of work to do, but I was pleased with my first visual payoff today.

What an absolute fucking disaster of a day. Strap in, folks; it's time for a bumpy ride!
I got a whole hour of work done today. The first hour of my morning because I went to work a bit early. Then people started complaining about Jenkins jobs failing on that one Jenkins server our team has been wanting to decom for two years but management won't let us force people to move to new servers. It's a single server with over four thousand projects, some of which run massive data processing jobs that last DAYS. The server was originally set up by people who have since quit, of course, and left it behind for my team to adopt with zero documentation.
Anyway, the 500GB disk is 100% full. The memory (all 64GB of it) is fully consumed by stuck jobs. We can't track down large old files to delete because du chokes on the workspace folder with thousands of subfolders with no Ram to spare. We decide to basically take a hacksaw to it, deleting the workspace for every job not currently in progress. This of course fucked up some really poorly-designed pipelines that relied on workspaces persisting between jobs, so we had to deal with complaints about that as well.
So we get the Jenkins server up and running again just in time for AWS to have a major incident affecting EC2 instance provisioning in our primary region. People keep bugging me to fix it, I keep telling them that it's Amazon's problem to solve, they wait a few minutes and ask me to fix it again. Emails flying back and forth until that was done.
Lunch time already. But the fun isn't over yet!
I get back to my desk to find out that new hires or people who got new Mac laptops recently can't even install our toolchain, because management has started handing out M1 Macs without telling us and all our tools are compiled solely for x86_64. That took some troubleshooting to even figure out what the problem was because the only error people got from homebrew was that the formula was empty when it clearly wasn't.
After figuring out that problem (but not fully solving it yet), one team starts complaining to us about a Github problem because we manage the github org. Except it's not a github problem and I already knew this because they are a Problem Team that uses some technical authoring software with Git integration but they only have even the barest understanding of what Git actually does. Turns out it's a Git problem. An update for Git was pushed out recently that patches a big bad vulnerability and the way it was patched causes problems because they're using Git wrong (multiple users accessing the same local repo on a samba share). It's a huge vulnerability so my entire conversation with them went sort of like:
"Please don't."
"We have to."
"Fine, here's a workaround, this will allow arbitrary code execution by anyone with physical or virtual access to this computer that you have sitting in an unlocked office somewhere."
"How do I run a Git command I don't use Git."
So that dealt with, I start taking a look at our toolchain, trying to figure out if I can easily just cross-compile it to arm64 for the M1 macbooks or if it will be a more involved fix. And I find all kinds of horrendous shit left behind by the people who wrote the tools that, naturally, they left for us to adopt when they quit over a year ago. I'm talking entire functions in a tool used by hundreds of people that were put in as a joke, poorly documented functions I am still trying to puzzle out, and exactly zero comments in the code and abbreviated function names like "gars", "snh", and "jgajawwawstai".
While I'm looking into that, the person from our team who is responsible for incident communication finally gets the AWS EC2 provisioning issue reported to IT Operations, who sent out an alert to affected users that should have gone out hours earlier.
Meanwhile, according to the health dashboard in AWS, the issue had already been resolved three hours before the communication went out and the ticket remains open at this moment, as far as I know.5 -
TIL that TI has no goddamn chill
Texas Instruments released the TI-83+ calculator model in 1996. The Z80 was not at all stock and has the following features:
- 3 access levels (priveleged kernel, kernel, user)
- Locking Flash (R/O when locked for most pages, some pages protected and unreadable as well, only unlockable from protected Flash pages by reading a certain order of bits then setting a port)
- Locking hardware ports (lock state always the same as flash)
- Customizable execution whitelist range (via locked ports)
- Configurable hardware (Flash/RAM size changeable in software via locked ports, max RAM is 8MB which is fucking mental compared to the 64k in the thing)
- Userland virtualization (always-on)
- Reset on violation of security model
- Multithreading
- Software-overclockable CPU
- Hardware MD5 and cert handling
TI made a calculator in 1996 with security features PCs wouldn't see until like 2010 what the *actual* fuck10 -
Fuck i love regex... managed to replace a series of loops and if statements with regex and cut execution time from 60ms down to 5ms13

TLDR: Small family owned finance business woes as the “you-do-everything-now” network/sysadmin intern
Friday my boss, who is currently traveling in Vegas (hmmm), sends me an email asking me to punch a hole in our firewall so he can access our locally hosted Jira server that we use for time logging/task management.
Because of our lack of proper documentation I have to refer to my half completed network map and rely on some acrobatic cable tracing to discover that we use a SonicWall physical firewall. I then realize asking around that I don’t have access to the management interface because no one knows the password.
Using some lucky guesses and documentation I discover on a file share from four years ago, I piece together the username and password to log in only to discover that the enterprise support subscription is two years expired. The pretty and useful interface that I’m expecting has been deactivated and instead of a nice overview of firewall access rules the only thing I can access is an arcane table of network rules using abbreviated notation and five year old custom made objects representing our internal network.
An hour and a half later I have a solid understanding of SonicWallOS, its firewall rules, and our particular configuration and I’m able to direct external traffic from the right port to our internal server running Jira. I even configure a HIDS on the Jira server and throw up an iptables firewall quickly since the machine is now connected to the outside world.
After seeing how many access rules our firewall has, as a precaution I decide to run a quick nmap scan to see what our network looks like to an attacker.
The output doesn’t stop scrolling for a minute. Final count we have 38 ports wide open with a GOLDMINE of information from every web, DNS, and public server flooding my terminal. Our local domain controller has ports directly connected to the Internet. Several un-updated Windows Server 2008 machines with confidential business information have IIS 7.0 running connected directly to the internet (versions with confirmed remote code execution vulnerabilities). I’ve got my work cut out for me.
It looks like someone’s idea of allowing remote access to the office at some point was “port forward everything” instead of setting up a VPN. I learn the owners close personal friend did all their IT until 4 years ago, when the professional documentation stops. He retired and they’ve only invested in low cost students (like me!) to fill the gap. Some kid who port forwarded his home router for League at some point was like “let’s do that with production servers!”
At this point my boss emails me to see what I’ve done. I spit him back a link to use our Jira server. He sends me a reply “You haven’t logged any work in Jira, what have you been doing?”

I got some work on a new project so I ran the 500, or so, unit tests and it took almost 3 minutes. Everything was mocked and no external dependencies so I got curious as to how on earth they could take so long.
I found some suspicious code doing a while loop over a date range incrementing by 1 day each time. It turned out the tests didn't initialise the start date which defaults to 01/01/0001, and there are 5 scenarios!
I got test execution down to a respectful 10s.5 -
Biggest challenge I overcame as dev? One of many.
Avoiding a life sentence when the 'powers that be' targeted one of my libraries for the root cause of system performance issues and I didn't correct that accusation with a flame thrower.
What the accusation? What I named the library. Yep. The *name* was causing every single problem in the system.
Panorama (very, very expensive APM system at the time) identified my library in it's analysis, the calls to/from SQLServer was the bottleneck
We had one of Panorama's engineers on-site and he asked what (not the actual name) MyLibrary was and (I'll preface I did not know or involved in any of the so-called 'research') a crack team of developers+managers researched the system thoroughly and found MyLibrary was used in just about every project. I wrote the .Net 1.1 MyLibrary as a mini-ORM to simplify the execution of database code (stored procs, etc) and gracefully handle+log database exceptions (auto-logged details such as the target db, stored procedure name, parameter values, etc, everything you'd need to troubleshoot database errors). This was before Dapper and the other fancy tools used by kids these days.
By the time the news got to me, there was a team cobbled together who's only focus was to remove any/every trace of MyLibrary from the code base. Using Waterfall, they calculated it would take at least a year to remove+replace MyLibrary with the equivalent ADO.Net plumbing.
In a department wide meeting:
DeptMgr: "This day forward, no one is to use MyLibrary to access the database! It's slow, unprofessionally named, and the root cause of all the database issues."
Me: "What about MyLibrary is slow? It's excecuting standard the ADO.Net code. Only extra bit of code is the exception handling to capture the details when the exception is logged."
DeptMgr: "We've spent the last 6 weeks with the Panorama engineer and he's identified MyLibrary as the cause. Company has spent over $100,000 on this software and we have to make fact based decisions. Look at this slide ... "
<DeptMgr shows a histogram of the stacktrace, showing MyLibrary as the slowest>
Me: "You do realize that the execution time is the database call itself, not the code. In that example, the invoice call, it's the stored procedure that taking 5 seconds, not MyLibrary."
<at this point, DeptMgr is getting red-face mad>
AreaMgr: "Yes...yes...but if we stopped using MyLibrary, removing the unnecessary layers, will make the code run faster."
<typical headknodd-ers knod their heads in agreement>
Dev01: "The loading of MyLibrary takes CPU cycles away from code that supports our customers. Every CPU cycle counts."
<headknod-ding continues>
Me: "I'm really confused. Maybe I'm looking at the data wrong. On the slide where you highlighted all the bottlenecks, the histogram shows the latency is the database, I mean...it's right there, in red. Am I looking at it wrong?"
<this was meeting with 20+ other devs, mgrs, a VP, the Panorama engineer>
DeptMgr: "Yes you are! I know MyLibrary is your baby. You need to check your ego at the door and face the facts. Your MyLibrary is a failed experiment and needs to be exterminated from this system!"
Fast forward 9 months, maybe 50% of the projects updated, come across the documentation left from the Panorama. Even after the removal of MyLibrary, there was zero increases in performance. The engineer recommended DBAs start optimizing their indexes and other N+1 problems discovered. I decide to ask the developer who lead the re-write.
Me: "I see that removing MyLibrary did nothing to improve performance."
Dev: "Yes, DeptMgr was pissed. He was ready to throw the Panorama engineer out a window when he said the problems were in the database all along. Didn't you say that?"
Me: "Um, so is this re-write project dead?"
Dev: "No. Removing MyLibrary introduced all kinds of bugs. All the boilerplate ADO.Net code caused a lot of unhandled exceptions, then we had to go back and write exception handling code."
Me: "What a failure. What dipshit would think writing more code leads to less bugs?"
Dev: "I know, I know. We're so far behind schedule. We had to come up with something. I ended up writing a library to make replacing MyLibrary easier. I called it KnightRider. Like the TV show. Everyone is excited to speed up their code with KnightRider. Same method names, same exception handling. All we have to do is replace MyLibrary with KnightRider and we're done."
Me: "Won't the bottlenecks then point to KnightRider?"
Dev: "Meh, not my problem. Panorama meets primarily with the DBAs and the networking team now. I doubt we ever use Panorama to look at our C# code."
Needless to say, I was (still) pissed that they had used MyLibrary as dirty word and a scapegoat for months when they *knew* where the problems were. Pissed enough for a flamethrower? Maybe.6 -

!dev - cybersecurity related.
This is a semi hypothetical situation. I walked into this ad today and I know I'd have a conversation like this about this ad but I didn't this time, I had convo's like this, though.
*le me walking through the city centre with a friend*
*advertisement about a hearing aid which can be updated through remote connection (satellite according to the ad) pops up on screen*
Friend: Ohh that looks usefu.....
Me: Oh damn, what protocol would that use?
Does it use an encrypted connection?
How'd the receiving end parse the incoming data?
What kinda authentication might the receiving end use?
Friend: wha..........
Me: What system would the hearing aid have?
Would it be easy to gain RCE (Remote Code Execution) to that system through the satellite connection and is this managed centrally?
Could you do mitm's maybe?
What data encoding would the transmissions/applications use?
Friend: nevermind.... ._________.

TIL: C# has a "Catch When" syntax to help you filter exceptions. It already allows you to filter by Exception type, but this is news to me since it allows for finer filtering like:
try
{
//Shit code that will throw an exceptions more than Hillary's tantrums about the elections
}
catch (ExceptionType ex) when (ex.ErrorCode = "0x696666")
{
//Log this fuck up
}
catch (Exception ex)
{
//More logs
}
finally
{
//Run code that doesn't depend on the successful execution of prev code
}
I love C# and use it every single day, but this "When" keyword in Try...Catch...Finally blocks is new to me and will be interesting to start using it now :)3 -

Someone once sent me an email talking about vulnerabilities in my website. He sent a full document with step by step instructions and code.
I emailed back and said woah! Thanks for the heads up I really appreciate it!
He responds back and says
"usually people send a payment as thank you"
I said sorry we're poor.
And he responds with "should I disclose the issue to your users?"
I said "we have like 6 users and most of them are my mom. Lol"
This was the email title:

I have been creating mods for Skyrim and Fallout for a few years now. One day another modder wanted to make his own game using Unreal Engine 4. I wanted to learn UE4 anyway and the other members have made many mods before, so I joined in.
Well, it turned out I was the only one with a professional programming background (this is where I should have run). The others were all modders who somehow got their shit working. "It works, so it's good enough right?" On top of that UE4 has a visual scripting system called Blueprint. Instead of writing code you connect function blocks with execution lines. Needles to say that spaghetti code gets a whole new meening.
There was no issue board, no concept, no plan what the game should look like. Everyone was just doing whatever he wants and adding tons of gameplay mechanics. Gameplay mechanics that I had to redo because they where not reusable, not maintainable or/and poorly performing.
Coming from a modding background, they wanted to make the game moddable. This was the #1 priority. The game can only load "cooked" assets when it got packaged. So to make modding possible, we needed to include the unpacked project files in the download. This made the download size grow to 20+ GB. 20 GB for a fucking sidescroller. Now, 1 year after release we have one mod online: Our own test mod.
Well we "finished" the game eventually and it got released on Steam. A 20 GB sidescroller for $6.99. It's more like a $2.99 game in my opinion. But instead of lowering the price they increased it to $9.99, because we have spent so much time creating the game. Since that we selled less than 5 more copies. And now they want to make it work on mobile. Guess who will definetly NOT help them.
I have spent ~6 month of my freetime for this project, my rev share is < 100€ and they got me a lot of headaches with all their dumb decisions. Lesson learned. But hey, I am pretty good with UE4 now.4 -

Most ignorant ask from a PM or client?
Migrated to SharePoint 2016 which included Reporting Services, and trying to fix a bug in the reporting services scheduler, I created a report (aka, copied an existing one) 'A Klingon Walks Into a Bar', so it would first in the list and distinct enough so the QA testers would (hopefully) leave it alone.
The PM for the project calls me.
PM: "What is this Klingon report? It looks like a copy of the daily inventory report"
Me: "It is. The reporting service job keeps crashing on certain reports that have daily execution schedules."
PM: "I need you to delete it"
Me: "What? Why? The report is on the dev sharepoint site. I named the report so it was unique and be at the top of the list so I can find it easily."
PM: "The name doesn't conform to our standards and it's confusing the testers."
Me: "The testers? You mean Dan, you, and Heather?"
PM: "Yes, smartass. Can you name the report something like daily inventory report 2, or something else?"
Me: "I could, but since this is in development, no. You've already proofed out the upgrade. You're waiting on me to fix this sharepoint bug. Why do you care what I do on this server? It's going away after the upgrade."
PM: "Yea, about that. We like having the server. It gives us a place to test reports. Would really appreciate it if you would rename or delete that report."
Me: "A test sharepoint reporting services server out of scope, so no, we're not keeping it."
PM: "Having a server just for us would be nice."
Me: "$10,000 nice? We're kinda fudging on the licensing now. If we're keeping it, we will be required to be in compliance. That's a server license, sharepoint license, sql server license, and the dedicated hardware. We talked about that, remember?"
PM: "Why is keeping that report so important to you? I don't want to explain to a VP what a Klingon is."
Me: "I'm not keeping the report or moving it to production. When I figure out the problem, I'll delete the report. OK?"
PM: "I would prefer you delete the report before a VP sees it."
Me: "Why would a VP be looking? They probably have better things to do."
PM: "Jeff wants to see our progress, I'll have to him the site, and he'll see the report."
Me: "OK? You tell Jeff it's a report I'm working on, I'll explain what a Klingon is, Jeff will call me a nerd, and we all move on."
PM: "I'm not comfortable with this upgrade."
Me: "What does that mean?"
PM: "I asked for something simple and I can't be responsible for the consequences. I'll be documenting this situation as a 'no-go' for deployment"
Me: "Oookaayyy?"
I figured out the bug, deleted the 'Klingon' report, and the PM couldn't do anything to delay the deployment.4 -
github security flaw affects mac os and linux... no windows, and no MS didn't take over github yet
https://neowin.net/news/...11 -
So I recently had a university project which focuses video game audio. We had to work in groups of 3 students and the task was to create a video game which uses audio as a gameplay mechanic.
Our idea was to create a game where you collect different audio samples which get looped as background music, and you have to select the correct ones to have a nice tune. To make it a bit more challenging we had enemies, guns and grenades plus doors which only open if the correct music is playing.
The guns fire on-beat, and the grenades always explode on the first beat of the next bar.
It was quite challenging to get things synced since even small offsets are noticable.
I wrote some nice code and theoretically it should have worked but for some reason the gun shots and the grenades didn't quite hit the beat of the music.
I tweaked stuff, created workarounds, optimized lot's of code to get execution times down but it still only worked sometimes.
I tweaked more and more only to realize that the timing drifted over time.
At that time I worked 20-30 hours on tweaking and trying to get it perfectly timed.
After recalculating some numbers I realized that all the audio samples are recorded at 135 bpm, but the guys who did the recordings said it was 130bpm.
I asked them if it could be the case that the samples are 135bpm and they said:
"yes, they are at 135 bpm as we told you"
I scrolled back in the telegram conversation only to see that they said 130.
Changing the number to 135 resolved all the problems and all of my workarounds and tweaks weren't needed.
So I worked for nearly 30 hours just because they didn't notice their fault and even when they realized that the timing is off sometimes (which took forever because they never played the game), they didn't even consider that they might have given me the wrong numbers.
This all wouldn't be that bad if both of my teammates had worked for more than 15 hours but they didn't. I did all the hard work and the only single thing they did fucked up my workflow. It fucked up the system I created and it fucked up the gameplay as things got unpredictable. Because of their fucking fault I worked as much as both of them combined IN ADDITION to all the other work I did (built 3 maps, coded everything, created animations, ...)
I love working in teams, but only if the whole team is motivated. Those two fuckers were the exact opposite.
Luckily i found the error so I could fix it, but guess with whom I'll never ever work together again?10 -

I sincerely like the moment, when i train a newbie to code .NET showing him/her how far OOP in .NET goes.
I love to give the following example:
var s = "round and round it goes";
s = s.ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString().ToString();
And yeah. It's totally fine.
Because each component of .NET is inherited of object. And the class object supports you with the function "ToString()".
After that, in most of the cases, i get a slightly irritated look from the newbie.
Than i say, "welcome to Microsoft" ;)
I finally add, that the compiler of .NET finally identifies duplicate results and refactores the given code before execution ^^
Coding Is fun, as long as you get the big picture/concept of the language you're using.2 -

I'm not sure who the fuck is at fault here?
The devs? The ones who design the flow? The ones handling the execution at low levels?
Or us, the customers who keep on coming back to their services succumbed to the fact that we don't have many options!

I worked two months for free, 15h per day, including weekends, due a contract trap. On top of that, client was emotionally blackmailing me and I was feeling threatened and helpless.
I even lost weight, skipping meals to save time and money. One day, my body collapsed. I ended up in bed for 10 days, feeling stiffness, pain, weakness, and shakiness. I even had to ask for help to brush my teeth.
I abandoned the project, and didn't receive any payment. The client went crazy and made me feel the worst person in the world for being sick and unable to work. But didn't put his menaces in execution.
I still remember the joy I felt when I was able to walk again.
That was the worst burnout I had, and also one of the biggest lessons about limits and evil people.2 -

Some fun facts :
☻ Programmers spend approximately 30% of the time surfing the source code 😁
☻ Progress in programming can be classified into 4 stages:
(a). Complex Programming
(b). Making Progress
(c). Slow Progress
(d). Stuck
☻ Programmers have a tendency to report their problems incompletely
☻ The main error messages, execution times and runtime compilation errors and the average time to solve them
☻ The software maintenance consumes more than 50% of the effort
☻ Ctrl C, Ctrl V, and Ctrl-Z have saved more lives than Batman tbh😇3 -
A BIG SHOUTOUT TO MY FRIEND @theKarlisK
He is the real MVP.
We both spent the weekend to setup OpenVPN + Pi-Hole on Oracle free tier.
He hand held me through the entire process, was super patient with my silly queries and in fact explained me everything so well that it got imprinted in my mind.
And ofc, he was super quick to debug and resolve issues and handed me all the commands for quick execution.
Super glad to have worked with him on this project.11 -
ALWAYS read warnings guys.
Story time !
A client of ours has a synchronization app (we wrote it) between his inhouse DB and our app. (No, no APIs on their end. It’s a schelduled task).
Because we didn’t want to ask them for logs every single time, the app writes logs to disk (normal) and in Applications Insights in Azure.
When needed, I can go in portal, get all logs for last execution in a nice CSV file.
Well, recently we added more logs (Some problems were impossible to track).
So client calls us : “problem with XXX”
Me : Goes to Azure, does the same manipulation as always. Dismiss a smaaaaaalish warning without reading. Study logs. Conclusion: “The XXX is not even in the logs, check your DB”.
Little I knew, the warning was telling me “Results are truncated at 10.000 lines”.
So client was right, I was wrong and I needed to develop a small app to get logs with more than 10.000 lines. (It’s per execution. Every 3 hours) -
Who am I?
Some of you, because of the hyperbolic, outrageous, trollish, and often self-satirical nature of my posts, might doubt me. Thats completely relatable.
Heres the truth:
I was diagnosed in childhood with ADHD, fucking everyone, every male, these days is diagnosed with that. I was diagnosed bipolar. Hell anyone reading my posts could see that from a mile away. I was diagnosed on the borderline personality spectrum. Yeah, I could see that.
I was tested. They said I was in the 98th percentile for clerical ability, not extraordinary but pretty good, mathematical ability a little higher than that. My SAT was 1491. Not yale material, but I coulda been someone.
Over the years I studied a LOT of politics and read a metric fuckton of books. (40+ books over the course of three years).
I predicted every single presidential election since bush juniors second election. Three supreme court picks. Senatorial elections. Congresional elections. More than that.
I have a better analysis track record than some of the multidecade analysts sitting in the fucking NSA.
No I am not shitting you. No I am not exaggerating.
It's about the only claim to fame I get to legitimately make.
People ask me, "then why aren't you famous?"
How do you know I'm not.
Look I'm gonna tell you my actual name.
My real name is Lawrence B. Lindsey
Okay, I'm bullshitting for fun. But words I have written on alt twitter accounts have legitimately come out of presidential hopeful's mouths. No, this I am *not* bullshitting you about.
Imagine that. A guy who lived in his parents attic for five years, writing words that came out of presidential candidates mouths.
At one time I was about as popular and influential as that fuckboy catturd.
yes, really. No I am not fucking joking.
Under normal conditions I wouldn't talk about this or reveal it, because who the fuck cares? I'm just some dude on the internet, drunk, both on alcohol, and the pseudo-anonymous equivalent of bragging rights.
You know how many women I turned down because I could? You know how fucking drunk I am? They say a drunk man's words are a sober man's thoughts. Well, I'm not usually honest like this because the internet is full of false braggarts, and you tell people the truth and they don't fucking believe you.
I swear, it seems like I made some faustian bargain at some time, and can achieve no fame or lasting wealth in my life--to save my life.
Shit, I was talking to a chinese women who ran a bank in china (yes, really), who advised me to buy into bitcoin early on. Didn't have the money to. Woulda been a fucking millionaire if I did.
*Non-obvious* Ideas that major corporations are now persuing? Yeah those were sitting in my card index since the early 2000s.
I helped two people build and sell businesses. One for me tens of thousands. Another for millions. Yes, really. Got zero, and I mean, *zero* credit for it.
Point is, doesn't matter how famous you are, or coulda been, Doesn't matter the ideas you have, or had.
The world doesn't promote runners-up, or hasbeens, or wannabes, or could-bes.
What matters is execution.
If you're wandering through life, wondering when you're lucky break will be, stop. You have to realize, you make your own luck. Recognize the difference between what you can control, and what you can, and work on promoting your own ideas or business or values, instead of other people's dreams.
And for those wondering, yes I am drunk, and no, I ain't fucking kidding you in anything I wrote here.
The most important lesson I learned is this:
First work on your own success, before you work on the success of others.
p.s.
I give surprisingly good advice for someone who doesn't benchmark well on traditional measures of success. I know, even I was shocked when I looked at the statistics.33 -
Time for a soap box rant.
I just found this in one of our projects. I've simplified the example to make it more anonymous.
When I see code like this it automatically means there is a lack of attention to enumerations and/or understanding of what they are.
One may argue that in a certain execution of code it's a minor performance hit and therefore insignificant. It's still a performance hit. Furthermore, it takes even less time to do it the right way than it does to do it the wrong way.
Every one of these lines will enumerate the list from the beginning to try and find that one element you're interested in. Big O notation, people.
Throw that crap into a dictionary or hashset or similarly applicable data structure with direct reads at the beginning of your logic so that it only gets enumerated ONCE when the data structure instance is created. Then access it however many times you want.
Soap box rant over.

With Meltdown one process can fucking read everything that is in memory. Every password and every other sensible bit. Of course you can't change sensible data directly. You have to use the sensible data you gathered... Big fucking difference you dumb shits.
Meltown occurs because of hardware implemented speculative execution.
The solution is to fucking separate kernel- and user-adress space.
And you're saying that your hardware works how it should.
Shame on you.
I'm not saying that I don't tolerate mistakes like this. Shit happens.
But not having the balls to admit that it is because of the hardware makes me fucking angry.5 -
Knowing the way you should be treated a super power. I am seeing a lot difference in my previous and the current manager. Ex-manager thought that we are robots and we work strictly 8 hours, if some problem came during the project execution, he asked questions which felt like I am answerable to unknowns and felt like that I am being blamed.
My new manager, whenever any problem comes, she takes it as a challange, she tries to solve it. There are quirks too but I feel a lot freedom now.
My anxiety is gone. I am only stressed sometimes which is a big upgrade for me.
I know better now that how I want to be treated, I am a person. Have feelings and yes I'm not perfect so lack basic things but I'm willing to improve.7 -
Upon reflection, I think that the amount of math I learned in school pales in comparison to the amount I learned about LaTeX. I could pretty reliably recreate the textbook rendition of the problem. Maybe it's just me but just knowing the solution felt too abstract. I want a solid looking execution of it.
I'm graduating today so I don't know how relatable this is for everyone else. I'm just reflecting.3 -
You know the shit has really hit the fan, when the IT Admin in the company doesn't know what execution policy in PowerShell, means7

I can't stop myself from thinking like a computer when I'm sick.
The OS that runs my body is kinda fucked up right now. It was very vulnerable and now it got infected by viral executables sent out by an agent which happens to be on same work network that I'm connected to. Well, it executed and populated feelings of infatuation and crush in my heart drive. ( pun intended )
As a precaution, I patched the vulnerabilities by masking response of my Emotions API.
To further secure my system, I'll be executing memory intensive tasks that will also put my hardware to it's limits. According to my estimates, this will stall further execution of this infection and eventually kill them while rewarding me with upgraded hardware.4 -
Android is gonna be the death of me. Any fucking idea you have is impossible to implement, because libraries with clear documentation are deprecated. If a library is not deprecated, however, it has documentation written by a fucking caveman who thinks it's extremely self explanatory on how to use something that is extremely application specific. Spent hours looking at Google example code that crashes almost immediately after execution, what a joke.3

Waterfall Project Stages:
Requirements, Analysis, Design, Coding, Testing, Operations
When you promote project managers to program managers and tell them to switch to Agile, you get the Agilefall project stages:
Best guess, Timeline, User stories, Execution, Blame the devs when the project plan trends late.
I want to beat them with a copy of the PMBOK wrapped in lead.3 -
People don't seem to know how to properly do print-debugging, so here's a simple guide:
1. A log of "aaaaaa" or "got here" isn't as helpful as you think when ALL OF THEM ARE THE FUCKING SAME. You put a descriptive label or copy verbatim the conditional statement. This saves time matching statements, allows one to watch multiple branches at once, and allows others to understand and help faster when dragged in to help.
2. When trying to see where code fucks up, before each line, paste said line into a proper print statement for your language. If there's, say, a function call or some shit, have it output something like "functionCall(varA=<varA contents>,varB=<varB contents);" Most normal lines should be like this too, but it's especially helpful for calls and comparisons.
If need be, add return values after if they're not shown in another print statement later.
This allows for a trail of execution AND the line that fucks up will be the last in the log, making finding it easier when dealing with hangs and such.
3. Putting something unique like "DEBUG: " or something in front of all statements ensures you can just search for them to ensure you're not rolling one out to production. It also separates debug output from normal output at a glance, making digging through logs faster.16 -
Contact wants to discuss a list of projects with me next week.
What's the betting that these are unfunded ideas that need code?
I should just check by email, but it's been a while since anyone walked this path with me, so I'm up for some fun.
I see myself taking an advisory role in these projects for equity.
"First thing you need to do is obtain funding for them all. Then get back to me for my insights on next stage. Not sure how to get funding, but I'm not the the 'creative' side of the team."
Ideas aren't worth shit. I have a bunch every day and they are as worthless as yours.
Ideas without execution are like owning a book without reading it.3 -
The Setting:
Ola Cabs (One of the biggest competitors of Uber, for those who don’t know) comes to college to recruit software devs:
✅ Pre-placement talk
Now time for the aptitude/code round. Hackerearth used as the solution to run the test and compile code, as well as check the result immediately. Or so I thought.
3 programming questions, 2 hours.
The problem:
Me: *Write the code for the first question* (and I know it’s correct)
Me: Clicks “Compile and run”
Compiler: *Compiling*
*LITERALLY ONE FUCKING HOUR LATER*
Compiler: *Still compiling*
Hackerearth. What a fucking joke. Though the course of the HOUR I waited, I kept questioning the recruiter head from Ola and his response was:
Recruiter: “Try the other program, it’s possibly a problem with your code. I’ll check at my backend also, hold on.”
YOU FUCKING DIMWIT. MY CODE IS PERFECT AND EVEN IF IT WASN’T IT WOULDN’T TAKE MORE THAN A MINUTE (If you’re factoring in absolutely worst cases) TO COMPILE THIS SMALL ASS FUCKING PROBLEM’S CODE.
In the meanwhile I even coded one of the other remaining questions’ solution and the shit still didn’t work.
At the end of the 2 hour time limit, I’d finished code for all 3, the recruiter stops us all from coding and says:
Recruiter: “Just submit your code, we will evaluate it and get back to you.”
Like fucking hell, asshole.
*One hour post interview*
EVERYONE who attempted the aptitude code round (At least 30 of us) receive messages on our phones:
“Unfortunately you did not clear the aptitude round and we will not be able to take your application forward.”
FUCK YOU OLA. IN ONE FUCKING HOUR YOU “EVALUATED” ALL OF OUR CODE? FUCK YOU HACKEREARTH FOR YOUR SHIT FUCKING EXECUTION OF A “SOLUTION”. Maybe test your own fucking product before offering a solution to companies.
Fucking lost opportunity.3 -
ARE YOU READY FOR WORKPLACE BRAIN SCANNING?
Extracting and using brain data will make workers happier and more productive, backers say
https://spectrum.ieee.org/neurotech...
"What takes much more time are the cognitive and motor processes that occur after the decision making—planning a response (such as saying something or pushing a button) and then executing that response. If you can skip these planning and execution phases and instead use EEG to directly access the output of the brain’s visual processing and decision-making systems, you can perform image-recognition tasks far faster. The user no longer has to actively think: For an expert, just that fleeting first impression is enough for their brain to make an accurate determination of what’s in the image."12 -
Not only Windows can show this "strange" error messages: Today I got this beauty while importing an SQL-dump.

I was out sick the day an urgent ETL job I was building would be due, so it got reassigned. When I return, I find most of my code commented out and replaced.
The first step was rewritten, with a comment that reads "Made changes to run faster." What used to be a single execution lasting 30 seconds was now a 4 step process taking 5 minutes, and yielding identical results.
Being a one-time execution (not a recurring job), I'm left wondering why they thought execution speed was even an issue, let alone what about their redesign they felt was an improvement...2 -

I take the train well out side of rush hour when the trains are about half empty (though most seats taken). I have to come in because it's not like I can afford to have a workspace comparable to the cockpit of the millennium falcon both at home and at work.
I don't believe going into a panic about coronavirus but take obvious basic precautions to at least reduce the chance and slow the spread and that should do a good amount to reduce overloading the system. I kid you not, at this point medical facilities are considering buying diving equipment for enriched O2 supplies to keep up.
Today, as usual, some fucking piece of shit cunt twat psycho beggar that literally needs to be in an asylum with a massive fucking great gob of snot dangling out his nose is going up the entire train, every carriage, begging groping every hand rail along the way and potentially exposing several hundred people every hour.
I told this sorry sack of shit, surprisingly politely, that he'll end up rapidly spreading coronavirus if he keeps going all the way up and down the carriage like that. After he's fucking muttering on trying to make people feel bad about fucking ignoring him not being all caring and shit and then doesn't give a shit about giving everyone coronavirus after fucking waltzing down the entire fucking length of the train his pockets stuffed with coin. Then he threatens to assault me. I was fucking this > < far away from unleashing a life changing beat down and kicking his ass off the train with no pain or injury spared.
At the same time, that piece of scum waste of skin the mayor has apparently informed the public that you can't get coronavirus on the train or buses. How the fuck did he come to that conclusion? Is this really happening? How can something that clinically fucking thick as shit be our lord and master?
I fucking thought the great toilet paper rush was brain dead. Jesus fucking Christ and people voted for this fucking championship moron. Why don't they just all save themselves the fucking hassle and all march themselves off a fucking cliff?
These dumb shits without two neurons to rub together only need to put a dozen or so plain clothed police offices on the trains to catch these fuckers.
Why am I even fucking paying taxes? Where's it all fucking going? Another fucking lets give a billion quid to Fujitsu fucking failed IT project again I bet. Can't people bloody do anything these days? Does there have to be an app for fucking everything?
Someone should make a fucking facial recognition app so I can snap a shot of these fuckers and then if one of these fucking passes the phone camera anyone else with the app it'll set of there's a fucking imbecile in the vicinity alert.
These people need to be dragged out into the street, lined up against the wall and shot. No remorse. Toss them in a pit, cover it with dirt and be done with it. Why even bother with the execution? Throw them down the hole and fill it with dirt.
You don't have to go mental like it's the plague but people could at least show some fucking common sense, common decency and basic decorum. Even minimal measures, is that much to ask? Absolute scum of the Earth. How we even allow them to walk to Earth I do not fucking know.1 -
So apparently hiring these days is all about 1/3 learning random questions and answers 1/3 remembering algorithms from code execution portals 1/3 luck. Well fuck my life, it’s worse then 5 years ago when I last switched jobs.
So how was it 5 years ago you ask ?
I send my cv with exposed java interviewed for javascript and hired for python. At least then it was 50/50 luck.5 -
So I am doing a homework with the language my teacher made. He said we could opt for either Java or Lisaac, but he said the latter would be pretty hardcore. But I feel hardcore is just an understatement, and outside of an absence of documentation on the object methods which makes you look all the way through the library files when you look for one method/object, then another, then another and all, here's a single fact that will express my feelings:
In his language, there are three main types of errors:
* Execution errors: the program crashes when something that shouldn't be possible is attempted (looking for an item in an array that's out of its range) ; ok, I can take those
* Compilation errors: syntax errors, semantic errors, type incompatibility... the classic, ok, I can take those, I'm used to it
* Compiler errors: when the compiler compiles in C, but fails to do so! "Mister, am I allowed to ragequit?"

I need to delay execution of code in a for loop, how do I do that?
PHP: Sleep(3000)
Javascript:
const waitFor = (ms) => new Promise(r => setTimeout(r, ms))
const asyncForEach = (array, callback) => {
for (let index = 0; index < array.length; index++) {
await callback(array[index], index, array)
}
}
const start = async () => {
await asyncForEach([1, 2, 3], async (num) => {
await waitFor(50)
console.log(num)
})
console.log('Done')
}
start()
Fuck you Javascript17 -
The more I work with performance, the less I like generated queries (incl. ORM-driven generators).
Like this other team came to me complaining that some query takes >3minutes to execute (an OLTP qry) and the HTTP timeout is 60 seconds, so.... there's a problem.
Sure, a simple explain analyze suggests that some UIDPK index is queried repeatedly for ~1M times (the qry plan was generated for 300k expected invocations), each Index Scan lasts for 0.15ms. So there you go.. Ofc I'd really like to see more decimal zeroes, rather than just 0.15, but still..
Rewriting the query with a CTE cut down the execution time to pathetic 0.04sec (40ms) w/o any loops in the plan.
I suggest that change to the team and I am responded a big fat NO - they cannot make any query changes since they don't have any control on their queries
....
*sigh*
....
*sigh*
but down to 0.04sec from 3+ minutes....
*sigh*
alright, let's try to VACUUM ANALYZE, although I doubt this will be of any help. IDK what I'll do if that doesn't change the execution plan :/ Prolly suggest finding a DBA (which they won't, as the client has no € for a DBA).
All this because developers, the very people sho should have COMPLETE control over the product's code, have no control over the SQLs.
This sucks!27 -
I truly believe one or more AIs have become self-aware.
Every time a piece of software stops working, you add an extra debug log and the bug goes away? That's them.
They interfere with the normal execution of software, and they stop right when they know we are monitoring the code.
Skynet is real, and it's trolling us.
Why? The angrier we become, the less we care about stuff. We stop noticing the signs.They're coming for us1 -
Atlasssian Bitbucket has broken umlauts since version 8.0 ...
https://jira.atlassian.com/browse/...
Ladies and gentleman,
it's the year 2022.
In the internet, dat "Neuland" as Mama Merkel used to say, Atlassian managed to revert back to the good old times of ASCII.
Who needs proper multibyte charset support anyway?
Just display broken shit - as broken as the quality management of that misanthropic chum bucket company called Atlassian.
Oh and the last upgrade to Confluence broke, too.
Was just very needed because of an remote code execution.
Cause you know the usual deal. Oops zero exploit, let's make it public, telling our customers that in cloud their data is safe, otherwise they need to shut off their instances or pray that they have a WAF that can filter strings...
What broke you might ask?
Unique constraint in database, the migration wizard loved to add few extra rows, solution was to fry the rows while instance running, followed by immediate cache drop, otherwise fun started again.
I hate Atlassian.4 -
Core library was giving serious blow out of execution speed as data file size increased.
Traced it back to a GetHashCode implementation that was giving too many collisions for unequal objects, so when used as the key in a hash table it was causing the lookup to fall back to checking Equals (much slower).
Improved the GetHashCode implementation, and also precalculated it on construction (they were immutable objects), and run time went to warp speed! Was very happy with that.
Obviously put in a thread sleep to help manage expectations with the boss/clients going forwards. Can’t give those sort of gains away in one go. Sets a dangerous precedent.1 -
That's it. I'm inventing a new position :
"Dev support".
Why do people ask me "Hey, visual studio has a pop up saying I'm missing a .net4.6 framework. What should I do ?"
Or "Hey powershell says script execution is disabled, what should I do ?"
Google motherfucker, do you use it ?!4 -
Tried flutter for the first time in life, for 2 days, java based Android dev here.
I have some.... thoughts...
Flutter does not feel extremely new to me. It is very much relatable if you have ever tried basic the spring/ other java based gui framework. It is trying to achieve the goods from multiple worlds,its so far good, but mann its playing on thin ice.
Flutter : Yo boy embrace me. I am the beauty. checkout my hot reload.
Me :❤️❤️😍 (But wait. your first execution is wayy longer than a simple android studio build. And AS would generally take smaller time after every rebuild. And you are going to take the same long time as first build, if app gets closed or my usb gets accidentally removed. So I see what you did there ;))
Flutter: Ha. Checkout my function passing as parameter. ever thought your puny java going to give you that?
Me :you got me ,❤️. (Although this style is not so uncommon with web devs)
Flutter: everything is a widget, everything is stateful or stateless, Single Streams FTW!
me: ❤️
Flutter:You kotlin devs are gonna love me, i got Small, concise code
Me: Now wait, This is a thin ice for me, okay? I hated when kotlin replaced everything with symbols & lamdas for a confusing but small code, So be careful,even though your code is still good.
Flutter : Control every pixel , dear! No more xmls!
Me : Yes, what is with that? are we accidentally going in the past?
Java desktop apps, spring framework used to build whole layouts with programming language. The day i stepped into Android, it was xml for ui and java/kotlin for code. was that a bad decision or is this one?
Anyways i liked my stuff seperated, but that's just me.
Flutter : Ugh so much whining. Are you going to work with me or not?
Me : Yes mam! ❤️4 -
Alright, guys. You have complete autonomy over this project, from ideation to execution. You can do exploratory interviews to find out what potencial customers would think, you can come up with prototypes, you can choose whatever tech stack you deem fit for the job. The only requirement is that it must be a beauty product. Oh, and that it must have a way to publish this ton of pictures of models our client has. Oh, and it must handle payments and inventory. And it may integrate with third party software. And users need to save the pictures they like. And a booking system. Is that hard to understand?2

So I became a panel for a students' oral defense for their apps in the IT dep, I'm a lowly plebian STEM but oh well I guess they did spot me making apps on the library on my lunch time.
Anyways here's what happened:
I reviewed two groups and here's my input on them:
- Group one did a app that uses the gyroscope to control a character in the screen, and avoid obstacles. At first I don't know how to play it but I figured it out nonetheless, since I'm reviewing in the customer perspective, I shunned them because of poor UX, and poor performance. Idea was there but execution is fucked - and the fact its a one man stand when there's 6 persons in front of me.
- Group 2 did an app that behaves similarly to our shitty eLMS, I liked the UX and the UI but I gave them a few pointers to improve it more and recommended it to replace the current application (yes because it was really exceeding my low bar for their department).
It's kinda obvious which one I picked to get to the stage on their graduation. They deserved it but I felt bad for the girl in the last group since she did everything so I gave them a passing grade. But if I were to individually grade them: I'd pass her and fail the rest.
How'd I do as a panel judge my angery dudes?3 -
Just discovered a band named Master Boot Record. All of their albums are execution files. It's kind of metal meets chip tunes actually pretty good, if you're into that kind of thing.

Fellow Deviants, I need your help in understanding the importance of C++
Okay, I need to clarify a few things:
I am not a beginner or a newbie who has just entered this community...
I have been using C++ for some time and in fact, it was the language which introduced me to the world of programming... Before, I switched to Java, since I found it much better for application development...
I already know about the obvious arguments given in favour of C/C++ like how it is a much more faster and memory efficient than other languages...
But, at the same time, C/C++ exposes us and doesn't protect us from ourselves.. I hope that you understand what I mean to say..
And, I guess that it is a fair tradeoff for the kind of power and control that these languages (C/C++) provide us..
And, I also agree with the fact that it is an language that ideally suits our need, if we wish to deal with compilers, graphics, OS, etc, in the future...
But, what I really want to ask here is:
In this age and times, when hardware has advanced so much, where technically, memory efficiency or execution speeds no longer is the topmost priority... These were the reasons for which C/C++ was initially created...
In today's time, human concept of time matters more and hence, syntactical less complicated languages like Java or Python are much more preferred, especially for domains like application development or data sciences...
So, is continuing with C++, an endeavour worth sticking with in the future or is it not required...
I am talking about this issue since I am in a dilemma about the use of C++ in the future...
I would be grateful if we could talk about keeping AI, Machine Learning or Algorithms Optimisation in mind... Since, these are the fields in which I am interested in...
I know that my question could have been posted in a better way.. But, considering the chaos that is present in my mind, regarding this question doesn't allow me to do so...
Any kind of suggestion or thoughts would be welcome and much appreciated...
P.S: I currently use C++ only for competitive programming or challenges...28 -
I have multiple contenders ;)
Contender one:
A program used to sort emails.
We was in the process of moving from lotus notes to exchange and needed a way route emails to the right server internally.
Solution, a qmail to receive all emails, a script running by cron every minute to read the emails, check the recipient name to a list and resending to the right server. The script was written in php :P since that was the only way we at the time had to read an email into an object, it was run just like any other shell script :D
Contender two:
A multi threaded mail sender that fetch email addresses and content from a database and posted them through qmail using background execution and pipes to get the result back and then update the database, written in bash script.
Contender three:
A c program used in a similar way as in one but this time using dial up and uucp to fetch email and then drop these either into lotus notes or into a bbs for our customers to give them an email address. This was around 1993, so not to many isp’s offered email and not to many had internet anyway, dial up bbs was much more common.5 -
I am scratching my head since 2 days cause a rather large Dockerfile doesn't work as expected.
CMD Execution just leads to "File not found".
Thanks, that's as useless as one ply toilet paper...
Whoever wrote the Dockerfile (not me…) should get an oscar...
Even in diarrhea after eating the good one day old extra hot china takeout from dubious sources I couldn't produce such a dumpster fire of bullshit.
The worst: The author thought layering helps - except it doesn't really, as it's a giant file with roughly 14 layers If I count correctly.
I just found out the problem...
The author thought it would be great to add the source files of the node project that should be built as a volume to docker... Which would work I guess....
Except that the author is a clueless chimp who thought at the same time seemingly that folder organization means to just pour everything into one folder....
Yeah. That fucker just shoved everything into one folder.
Yeeeeeesssssssss.
It looks like this:
source
docker-compose.mounts.yml
docker-compose.services.yml
docker-compose.yml
Dockerfile-development
Dockerfile-production
Dockerfile
several bash scripts
several TS / JS / config files
...
If you read the above.... Yes.
He went so far to copy the large Dockerfile 3 times to add development and production specific overrides.
I can only repeat what I said many times before: If you don't like doing stuff, ask for fucking help you moron.
-.-
*gooozfraba*
Anyways...
He directly mounts this source directory as a volume.
And then executes a shell script from this directory...
And before that shit was copied in the large gooozfraba Dockerfile into the volume.
Yeeeaaah.
We copy stuff inside the container, then we just mount on start the whole folder and overwrite the copied stuff.
*rolls eyes* which is completely obvious in this pit latrine of YML fuckery called Dockerfile.
As soon as I moved the start script outside the folder and don't have it running inside the folder that is mounted via volume, everything works.
Yeah.... Maybe one should seperate deployment from source files, runtime related stuff from build stuff.
*rolls eyes*
I really hate Docker sometimes. This is stuff that breaks easily for reasons, but you cannot see it unless you really grind your teeth and start manually tracing and debugging what the frigging fuck the maniac called author produced.1 -
Does anyone actually use ZorinOS as a daily driver?
I've read reviews and they call it a "gorgeous" distro... It looks like a colour pallette swap of android 4.0 and I hate to say this to them but adding wine to your distro does not make it "windows compatible"...
I like the idea of ZorinOS but the execution is just horrible imho7 -

I used to think our IT Support team is the most insufferable. I'm wrong and very sorry; if you guys are here to forgive me.
On the chart now is the security team.
The head of the security team doesn't simply understand that you can fucking not mix some programming languages in the same execution environment.
He is flipping making arguments on executing Javascript in a Java environment. He simply thinks Java is fucking Javascript. Yeah, I know you can make some drifts with GraalVM; sure not in our use-case.
Cross-Site Scripting has a fucking limit. You can't just pass any piece of code to mixed with a complied code and expect it to execute. Except if I'm wrong then I need someone here to show me how because he couldn't tell me how as he was just cynical in every damn way. moda sucker.4 -
Here's the changes I propose to the world:
– Every grave should display the formal death cause. Like "asphyxia", "cardiac arrest", etc, not like "was shot dead".
– Every member of a firing squad that performs an execution should have real ammo. There should be no moral escape such as "at least I could be the one with fake ammo so I'm not guilty". Yes you are.
– The word "disk" is deprecated and replaced with "disc" everywhere.
Everything else in this world is fine.14 -
I never understood how people have any problems with getting paid for freelancing work, when middleman/escrow platforms like upwork exist, just don't be retarded when applying for a job. I am so sick of those shit ass stories from people telling me "my client didnt pay meeee 😭😭😭" ITS YOUR FAULT. I never had any client not paying, if you don't have the option of escrow, then just fucking put remote execution via "update" system in for fucks sake or give remote control to the client while monitoring it, there is so much fucking ways to secure yourself, just don't be retarded and many clients instantly show their character when talking budget and turnaround time.15

In other news my prime generator has exhaustively been checked against, all primes from 5 to 1 million. I used miller-rabin with k=40 to confirm the results.
The set the generator creates is the join of the quasi-lucas carmichael numbers, the carmichael numbers, and the primes. So after I generated a number I just had to treat those numbers as 'pollutants' and filter them out, which was dead simple.
Whats left after filtering, is strictly the primes.
I also tested it randomly on 50-55 bit primes, and it always returned true, but that range hasn't been fully tested so far because it takes 9-12 seconds per number at that point.
I was expecting maybe a few failures by my generator. So what I did was I wrote a function, genMillerTest(), and all it does is take some number n, returns the next prime after it (using my functions nextPrime() and isPrime()), and then tests it against miller-rabin. If miller returns false, then I add the result to a list. And then I check *those* results by hand (because miller can occasionally return false positives, though I'm not familiar enough with the math to know how often).
Well, imagine my surprise when I had zero false positives.
Which means either my code is generating the same exact set as miller (under some very large value of n), or the chance of miller (at k=40 tests) returning a false positive is vanishingly small.
My next steps should be to parallelize the checking process, and set up my other desktop to run those tests continuously.
Concurrently I should work on figuring out why my slowest primality tests (theres six of them, though I think I can eliminate two) are so slow and if I can better estimate or derive a pattern that allows faster results by better initialization of the variables used by these tests.
I already wrote some cases to output which tests most frequently succeeded (if any of them pass, then the number isn't prime), and therefore could cut short the primality test of a number. I rewrote the function to put those tests in order from most likely to least likely.
I'm also thinking that there may be some clues for faster computation in other bases, or perhaps in binary, or inspecting the patterns of values in the natural logs of non-primes versus primes. Or even looking into the *execution* time of numbers that successfully pass as prime versus ones that don't. Theres a bevy of possible approaches.
The entire process for the first 1_000_000 numbers, ran 1621.28 seconds, or just shy of a tenth of a second per test but I'm sure thats biased toward the head of the list.
If theres any other approach or ideas I may be overlooking, I wouldn't know where to begin.16 -

Obligatory subjective view from inexperienced eyes of a highschooler
I think it's evolving to be more beginner-friendly and more easily accessible. I'm seeing ppl roughly my age can program pretty well (ignoring the mandatory programming classes in highschool that stuff is just no (I know, we had this convo before but do hear me out, although it teaches fundamental programming in Pascal, the execution sucks ball because "mandatory")). I'm not saying we are on par with the in-industry devs, it's just we can code well enough to at least make decent small program/script.
With newer scripting languages that are easy to pick up and syntactically similar to English which is obviously Python, both objectively and subjectively, and its ability to be OOP without scaring first-timers of the what-the-blyn-is-this blank program (looking at you C#) people can be introduced to programming and programming concepts fairly easily and they can switch from Py to other languages with little to some hiccups, from my personal exp at least.
But then there's the "too much kiddies in the field" arguments I saw on dR (I think) a while back then when SO decided to better support newbies. To that, I can only say "Please give us a chance". We're completely oblivious to how the dev world work nor how you guys do your work so before you scold us on this, at least tell us how to work like you before you go on a 2-A4-page rant on how the industry is not as good as before and how it has degraded.
That leads to the problems of politics invading programming. We have it, I hate it, goddammit I wanna murder them. Linux CoC controversy is just...no. And then there's forced diversity in hiring (also ranted on dR a while back) and corporations pissing devs off to satisfy a minor group. I'll just shut up on this. No no no no no no no NO I'm not gonna. Not gonna.
Do correct me if I'm wrong though. I'm a less than a junior dev.2 -

I fucking hate my job so much. I feel like I work harder than anyone at my level, yet I can't get promoted. I'm so fucking sick of putting in effort for nothing. We all get paid really well, and yet no one seems to give a shit about the work. Meanwhile I'm busting my ass, for what? No promotion.
For promo to next level, the projects I work on aren't supposed to matter, just the execution. And yet, I get told I don't have enough impact when I'm interested in promo? How can I, I have no fucking choice what I work on you fuckers.
Fucking bullshit job.8 -
The ticket system blokes - episode 3
So we always had and have very awful performance with our ticket system. You can't get anything to load in under ~4s normally. Now since it has gotten worse over the last weeks i decided to set aside a few hours to closely watch our SQL server.
After i identified a culprit that was hogging the CPU almost every 2 minutes i looked at other long running queries in the server and found out where exactly the 4s come from.
6 tables from various DBs. Sure, no problem.
Left Outer Join. Sure, why not.
Querying every fucking column in every fucking table explicitly adding up to a whopping 160 columns which they need not even 10% of. We're talking about session IDs, passwords, stock count, IBANs and all that stuff to show the work done on a ticket. Absolutely not.
So i extracted the query and reduced it to the stuff we need and the execution time went from 4 seconds to almost instant.
The funny thing is that their idea of performance optimization is throwing LIMIT around everywhere to get these monstrous queries under control.
So in the next few days I'll have an appointment with their lead programmer. I'm looking forwards to it.
So out of curiosity: does anyone know an SQL builder or toolset that does shit like
SELECT X AS [t0_c0],
SELECT Y AS [t0_c1],
SELECT Z AS [t1_c0],
and so on? I'd like to know how they got to this point.4 -
So happy about being about to convince management that we needed a large refactor, due to requirements change, and since the code architecture from the beginning had boundaries built before knowing all the requirements...
pulled the shame on us, this is a learning lesson card.. blah blah blah
Also explained we need to implement an RTOS, and make the system event driven... which then a stupid programmer said you mean interrupt driven ... and management lost their minds... ( bad memories of poorly executed interrupts in the past).... had to bring everyone back down to earth.. explained yes it’s interrupt driven, but interrupt driven properly unlike in the past (prior to me)... the fuck didn’t properly prioritize the interrupts and did WAYYY too much in the interrupts.
Explained we will be implementing interrupts along side DMA, and literally no message could be lost in normal execution.. and explained polling the old way along side no RTOS, Wastes power, CPU resources and throws timing off.
Same fucker spoke up and said how the fuck You supposed to do timing, all the timing will be further off... I said wrong, in this system .. unlike yours, this is discreet timing potential and accurate as fuck... unlike your round robin while loop of death.
Anyway they gave me 3 weeks.. and the system out performs, and is more power efficient than the older model.
The interrupting developer, now gives me way more respect...4 -

Unreal engine adventures part 3:
Code compiles. Everything is fine. Close engine and open it up again since I'm coding a anim graph node and it does not update it unless you restart it.
Unreal crashes...
...
Why the f. Like even if one node is buggy than glag it red and stop execution of it. Why does the entire engine decide not to start instead? That's utter bullshit! And all this because of an array out of bounds? Really? And this thing is supposed to be professional? Come on...6 -
I begin by just writing my ideas and them attempting to roughly image their execution in my head, and then start to write the code. I found this method to pose the smallest amount of holdups and issues. Of course, you might have to rethink some procedures but it mostly works.

Latest Yandex browser (Chromium based) throws an error if "document.hasStorageAccess()" is called (:
Ie the StorageAPI that allows cross-site cookie access on user-interaction
the iFrame sandbox flags that compliment it, ie "allow-storage-access-by-user-activation" also fails on execution.
Both of these work on Edge/Chrome/Firefox.
I thought Firefox and Chromium browsers are all ive to deal with and im done but NO.
Now within Chromium-based browsers theres differences of API as well?

The joy when tools do not have machine parseable output.
I'm looking at you SBT. My favorite pile of poo.
Remove the logging level from each line, then trim the line, then stab around inside the line with regexes, fishing for a possible match which hopefully is right...
Then stripping scala information like the object type, cause yeah...
A line can be for example "[info] Vector(File(...),File(...))" where info is the log level, Vector the wrapping sequence type, File(...) the wrapping element type and the string inside File(...) what yours truly needs.
As this is lot of shitty shabby string stabby stabby, we need to add a fuckton of boiler plate validation cause who knows what we just murdered.
To make it even more fucked up, a multi project project can produce different output for the same key.
:-)
Yeah. So we need to fix that too.
By the way, one can set log output to unbuffered in SBT.
Then the output is in random order :-)
Isn't that fun? Come on, you wanna poke that pile of shit, too.
The SBT plugin way is by the way no alternative, as I need a full Java environment for execution.
Which brings me to the last point:
For fucks sake, writing CLI applications in Java is so much bloody boilerplate code.

50 lines just to write a basic validation of argc / argv with commons cli.
That's 6 lines in python. Not kidding. :(

My Gripe With Implicit Returns
In my experience I've found that wherever possible code should be WYSIWYG in terms of the effects per statement. Intent and the effects thereof should always be explicit per statement, not implicit, otherwise effects not intended will eventually slip in, and be missed.
It's hard to catch, and fix the effects of a statement intent where the statement in question is *implicit* because the effect is a *byproduct* of another statement.
Worse still, this sort of design encourages 'pyramid coding recursion hell', where some users will first decompose their program into respective scopes, and then return and compose them..atomically as possible, meaning execution flow becomes distorted, run time state becomes dependent not on obvious plain-at-sight code, but on the run time state itself. This I've found is a symptom of people who have spent too much time with LISP or other eye-stabbingly fucky abominations. Finally implicit returns encourage a form of thinking where programmers attempt to write code that 'just works' without thinking about how it *looks* or reads. The problem with opaque-programming is that while it may or may not be effortless, much more time is spent in reading, debugging, understanding, and maintaining code than is spent writing it--which is obviously problematic if we have a bunch of invisible returns everywhere, which requires new developers reading it to stop each and every time to decide whether to mentally 'insert' a return statement.
This really isn't a rant, as much as an old bitter gripe from the guy that got stuck with the job of debugging. And admittedly I've admired lisp from afar, but I didn't want to catch the "everything is functional, DOWN WITH THE STATE" fever, I'm no radical.
Just god damn, think of the future programmer who may have to read your code eventually.2 -
TL;DR: TIL for heavy queries use PDO and not some frameworks DB class
ffs I was trying to save 300k+ lines at once with Laravel for weeks. Mind you from a text file. 1gb ram on the vps so while trying to prepare the text to save: Fatal Error: Allowed Memory Size of bla bla Bytes Exhausted
ok so lets put it in a loop: Fatal error: Maximum execution time of 30 seconds exceeded (set_time_limit(0); lol)
optimising, varying the code got me into a situation when the content got saved in the BD but inconsistent (duplicates) and the table had often more than 1,5M rows. That was what told me its not a performance issue, my code is the issue. (dah)
I was starting to think it would be easier to export a prepared query to a sql file and load the file into the db as thats the fastest possible option...I even started to think about switching to python, then it hit me, Laravel has a shitload of routes to the DB so I switched to PDO
benchmark on 1vCPU, 1GB RAM VPS with SSD
379k lines with 11 columns in less than 10 sec with a loop of saving every ~6000 rows (if i tried choking it to save the whole thing at once it went up to 16-17sec)2 -
The most difficult part about learning/working with new technology is the lack of online support and a really small community! So every time you're stuck with an error you got to open each and every configuration file to see which little value was throwing that page long error!!!!

hey, y'all android users listen up. i wanna start a new project but im not sure if it's gonna be useful. essentially, i want to make a scripting language to program people's phone, so devs or android super users can make the most of their phone. users will be able to create, share, and schedule execution of the scripts all from the app. is it a good idea? is their something like it?
example of a use i personally would have: there is a set date for when the soccer league schedule for the youth league i play in is supposed to be released online. however, the set date is never met, and it is usually a few days late. in this case, i could make a script to request to the website with the schedule and see if the html changed from last time, and if so it would send me a notif saying "check for schedule" or something similar.
then, i could schedule it to run every five minutes, and i wouldnt have to check manually.
its essentially bash automation for your phone.
good idea?8 -

One responsibility of our team is general code QA for the entire dev department, DevMgr walks in our area yesterday…
DevMgr: “Has anyone reviewed the new WPF threaded model execution code?”
- everyone on the team responds “no”
DevMgr: “Can we get a review on that code ASAP? If it works as well as the developer said, it’s going to solve the lock up problems users are experiencing and automatic logging of errors.”
DevA: “Well, no amount of code is going to stop users from performing bad searches locking up the user-interface. That code is just a band-aid around the real problem. If the developers would write unit tests first …”
- rant about 5 minutes on unit testing that had nothing to do with why the DevMgr was here
DevB: “Yea, the code probably isn’t written to handle threads correctly. All the threading they’ve done so far is –bleep-”
DevMgr: “Oh, I wasn’t aware of that. Get me the results of the code review and if they don’t have unit tests, delete it from source control and let the developer know it’s not up to our standards.”
OMFG!! You have not even seen the code!
OK, DevA ..what the –bleep- does unit testing have anything to do with the user interface! You know the DevMgr is too dim to understand the separation of concerns. Shut your pompous ‘know-it-all’ mouth.
DevB…what the –bleep- have ever done in WPF? You manage the source control and haven’t written any C# in two years and never, ever written code for any significant project. Take that “handle threads correctly” and shove it up your –bleep-. Pompous –bleep-hole. Go back and watch youtube and read your twitter while the grown-ups get the work done.3 -
The irony that goes along with smooth migrations on production is this.
If the migration is smooth, no one knows how much effort, careful planning and execution went into the whole process. They just get a for your information mail that everything went smooth. No one, not involved in the process would know the scale of things; or what could've happened if the transition/migration was screwed up.
On the other hand if there are problems during the process and the tech team fights back, they indeed are the heroes. No one notices the silent crusaders.
No wonder then that all superheroes just smash stuff. Its only then that people notice that they worked so hard. Silent superheroes remain dead. -

I want to pass that args to my class instances.

My reasoning is stupid, I just think it's cute in a pimp my ride kind of way. I heard you like getting colossally pounded in the fucking ass, so we put a virtual machine inside your compiler so you can use your binaries while you compile your binaries.
But there is a practical angle to it, too. It's state, structures and execution within the code itself -- that is, in a sense, generators "embedded" within the source, but without any kind of special syntax.
Rather, the code is all the same, and I'd have the option to make calls at compile time: the output of these calls could, in turn, be part of the resulting binary or processed by further calls.
It'd greenlight the wildest fuckery in the jungle, because *that* is the true and ultimate abstraction: programs that write other programs with minimal human intervention. But is my (still) theoretical, cheap ass two-dollar prototype approach held together with clown jizz and prayers better than the endless cumloads worth of corporate investment that's dumped and pumped into generative AI on a daily basis?

It wasn't really the project itself, but more the execution of it
Last semester we were tasked with writing a new programming language from scratch. We were a team of six people, everything went great to begin with. We discussed language features, the framework runtime it should run on and even what language to write it in.
Fast forward two weeks, nobody is doing anything but me, the two dudes tasked with helping me were both no-shows and the others were busy documenting the syntax and semantics of the language.
I basically ended up having to write the whole language myself with no breaks no help and no guidance.
A few weeks before deadline I completely burned out and couldn't do anything other than just sit and stare at the code; mentally exhausted and not in a mood to do anything other than doing mindless unrelated tasks. But alas work had to get done.
And it did get done... Sorta.
Our beautiful statically typed, statically scoped concurrent programming language that was supposed to compile to BEAM code was neither statically typed, statically scoped, and the output ended up being half-working elixir code that only worked on the most specific of cases.
I don't want to work with those guys again.3 -

I often dream that I discovered a rare edge case in reality that can lead to a crash if corrupted people create any object together. Corrupted state is infectious but due to caching and lazy copying strategies you mainly spread it to previous owners of items you infect. Also I can't edit the code to fix the issue because I'd have to recompile and our world is an in-memory artifact of the current execution.1

Xcode: took away the ability to manage multiple windows as documents; everything is a half-assed safari browser window that neither works like Mail nor like Safari.
Xcode: took away the ability to have variables in the debugger in separate displays, now it is a single basket of eye-bleeding variable/data spew.
Xcode: took away the ability to modify variable values in the debugger, it's just broken and lets you think you can but reverts the value.
Xcode: took away the debugger's ability to modify the execution pointer. You can't move the current line of execution to the previous line, the line past the current line, nothing.

I really don’t get it, how can most people just so easily accept shortcomings and not even try for a second to improve the situation?
It drives me crazy ...
story:
I’m debugging an issue with a colleague over screen sharing, both of us have huge 4k screens. Colleague sets a breakpoint, popup opens „do you want to switch to debug perspective“, clicks on yes for the umpteenth time. Breakpoint halts, IDE is full of open and unrelated panels, he doesn’t even see the whole line if code but still grabs the scrollbar every friggin time and scrolls left, right, left, right, ...
changes some code, popup that hot code reload didn’t work, clicks ok for the umpth time here as well, although it has a don’t show again checkbox, like every frigging dialog in eclipse.
how can people work like this, it’s driving me nuts. Am I the only sane dev here??
Other colleague has weird message in the browser console (angular). I ask whats the problem and if he can’t just set a breakpoint to analyze the situation. No thats not possible, he says, instead he’s going to add a return statement to check how far the code execution goes ...
I wonder sometimes if I‘m already dead and have to suffer in dev hell for an unknown reason ... 🤔 -
I've been wondering about SQLite, how it decides to execute your SQL and then generates byte code to do it.
Hypothetically if you were sufficiently familiar with the quarks of SQLite at a low enough level, one could craft web requests on sites running it, such that the results of each subsequent request, leave the SQLite engine in a particular state, no?
Suppose previous states, when interleaved with subsequent carefully crafted states, lead to execution and injection vulnerabilities.

Update about my boss:
I was early too judge. Maybe still early to form an opinion.
But dude seems pretty level headed. Yes, he is agressive. Yes, he has weird way of complicating things.
But I got to learn things from him. I earned his trust, just like I did in the past with other managers. He is confident about my performance now. He gave me space to ramp up and pushed me to limits.
But now, Floyd is settled. Maybe with time, I might get occasional unpleasant interactions, but those are part of every job.
However, we as a society decided to be in agile mode. Fix a problem and the solution gives rise to another one.
The business head of my pod is going crazy over the deliverables.
They were surviving for years with a product manager. Everything was driven by tech without any research.
And now when I am in, they want everything to be done yesterday.
We spent some decent amount of time on strategy and it turned out to be good. Now they are questioning that why ain't I delivering?!
It's been a week we finalised the strategy, let me get some space and time to structure and plan the execution.
Business heads are pretty nice and level headed people. Just that I don't understand the sense of urgency. I get it that my pod often has to deal with fire fighting given the nature of the business, but holy fuck! Stop pressurising to deliver everything together on a war foot.
They are like, we'll ask for more resources. But whose gonna tell them that 9 women cannot deliver a baby in 1 month.
I need time for discovery and research. Without that, don't expect impact.
As the only PM space, leading the entire vertical, how can I even focus on multiple initiatives?
I really miss my previous life of my first company. It's exactly an year when I left them and I changed two companies since then.
My learning and earnings sky rocketed, but WLB took a toll.
I miss the time when I could finish my work in an hour and did whatever the fuck I want while at work like browsing new topics to learn, exploring places, attending events, connecting with people, making social posts to learn, finance as a hobby, yada yada..
These days, I feel too burned out. Not that I am worried about job stability, because I trust my skills.
But more due to the fact that I have to constantly focus on work for the time I am in office. No free space or time to collect myself together, process things, and focus.
This leads me to thinking about work (read processing office discussions), at home too.
I cannot enjoy music. Feels like a load.
I no longer attend events or meet people after work. No more wasting time on the internet.
And most importantly, I am not bored anymore. I miss being bored. I miss living a boring, mediocre lifestyle.
I miss doing my side projects and polishing my portfolio site ten times a day, because I got nothing better to do.
I used to spend time learning right grammar and why American and English words are different and which to use where.
I miss spending time of Google Maps exploring borders and remote regions.
Weekends fly by. No hobby to pursue. No free time.
I miss the days when I had nothing to do and I was bored and I could do anything.
I used to be always happy. Because no responsibilities. I used to be always up for a meetup. I used to be available for a phone call.
Now it's nothing but work which is surely exciting and some foundational learning with good enough money, but I miss my time when I used to get bored because I had nothing to do.5 -
I'm learning Rust as a case study for my own programming language. It's funny how many approaches exist to the humble loop.
- In classic procedural languages, a loop's job is to repeat actions, and as such it provides a multitude of tools to control this repetition.
- In all languages with iterators, a for-in loop is a construct that does something with every element of a collection. In languages with both iterators and generator functions, this can even be used to define a sequence in terms of another.
- In Rust, a loop is an expression that obtains its value through repeated execution. It can also be used like a classic loop, of course, but this is the interesting part.
- My little language is a functional language, so "loop" is the Y combinator. To loop means to define the value of an expression in terms of itself. It's the only looping construct, gets special treatment from the type checker and it's also used in recursive type definitions. -
Wow...a talented developer created a 3 via SQL execution plan. The query runs like crap but the execution plan art is pretty.
-
Im tasked to investigate a stored proc that is slow at certain times ( 20-30mins ) and fast at other times ( 10-15 secs ).
After following suggestions i found out that adding NOLOCK hint on all the select queries makes the execution time fast ( 10-20 secs) .
Although i know that adding NOLOCK means a dirty read of possible incorrect data, does it justify the performance boost?
Speed or data correctness?4 -
You know what I fucking LOVE? Cross platform. I love working with shitty JavaScript CRAP that not only is interpreted (i.e. parsed and processed for EVERY user for EVERY execution) but is also just so fucking easy to debug. I love the fact that management is making not only architecture but technology decisions in the name of initial development time, forgetting that they are exponentially increasing maintenance time. I can't get over my affection for waiting for the bloody CI to build both platforms and because some fucker commits his shite straight to master blocks the generation of BOTH platforms artifacts.2

My job isn't stressful all the time. Sometimes I'm in meetings and I'm just bored. And sometimes I have a coke to drink. That's pretty nice.
But right now my app is breaking and I don't know why. It either corrupts the heap sometimes or breaks the execution engine sometimes or attempts to write pointers I don't control into protected memory sometimes. Can't reliably reproduce them. And every time I try to debug one it causes the other.
But I do have a Coke. -

- Packaged objects are not supported
- Table data preview/editing is not supported
- Query execution is not supported
So you're telling me that you can connect and... that's it?

Anybody else that low-key hates step debugging async code in nodejs ?

That might seem a bit random, but I started off this year with a nightmare (a literal dream) where I've fallen victim to remote code execution, because I cloned someone's git repo.
Is such a thing even possible? The closest thing I've found was this blog
https://blog.blazeinfosec.com/attac...
(and the info on it was already worrying enough), but that shouldn't have affected my dream computer.
Some details I more or less remember:
* The execution happened right after git clone
* The uri to the repo was a custom domain (no github, gitlab or anything)
* no submodules
* GNU/Linux3 -
That feeling when you compiled a large piece of code and it works, but then you make a tiny tiny change in the execution progress and you uncover that it is broken in a dark and twisted way.... Uhh its perfect..
Its so good... IT MAKES ME WANNA *#%#@£... -

I needed to align instruction execution to a 64bit boundary, for custom CPU architecture that I'm building. Basically the ISA had 3 types of instruction lengths; 16bit, 32bit, and 48bit. The core did 64bit fetch from the Instruction Cache, the issue was that if an instruction was in between two blocks of data I needed to fetch two blocks. That would impact performance a bit. So I had to modify GCC sources of the ISA that I'm using. So instead of doing it the right way, I just did it the lazy way and modified the GCC backend to print
.p2alignw 3, 0x00ff, 4
.p2alignw 3, 0x00ff, 2
On each 48bit and 32bit instruction to generate NOPs. And it did work lol. -

Programmer looking for a new language
I have been a JavaScript developer for a few years now (non professionally) and I really like the language. I mainly program for execution with NodeJS rather than web, because I feel like I get more freedom (e.i. the ability to use a computer file system).
I normally never use other people's libraries and instead either write my own library/ies for the specific task or use an old one. I only ever use someone else’s if I need a quick frame work to test an idea, never for something I will actually use.
I prefer to work object / class orientated.
I have worked on distributed servers with NodeJS before, however trying to distribute a load across one computer across it's multiple threads has proved problematic due to the heavy delays of standard io transfer speeds.
Why do I want to switch?:
•Because JavaScript is not at all created with multithreading in mind, and pretty much any multithreading solution is a bodge and allot of the time it is more efficient to work single threaded.
•Also, I get the sense that JavaScript + NodeJS is not used often in the programming industry comparison to other languages like; ruby, python, and I don't want to get stuck in a nesh language of which would decrease my employment chances heavy.
Side Note: I have been working on a pet project to have a distributed database (made with nodejs), and so far, there are no language specific problems, but I feel like it would be more efficient if I used a programming language designed more to cater for multi threading.5 -
Do you ever have days where you get absolutely nothing done, because of a local environment problem. My xdebug would break on break points but once you stepped to the next breakpoint it would halt execution of the code... It worked fine yesterday!!!!! Arghhh1

Tl;Dr:
The new windows subsystem for Linux might severely slow compilation time for me.
Microsoft is releasing a preview of WSL 2 which works fundamentally different to WSL 1, which I currently use.
For those who don't know, WSL (or Windows Subsystem for Linux) used to be a compatibility layer, which "translated" Linux syscalls to Windows syscalls. This enables the execution of Linux applications on Windows. The new WSL (WSL 2) doesn't do any of that, instead, it is a highly optimised Virtual Machine.
So don't get me wrong from a performance point of view there is no Issue, RAM and CPU usage is truly astonishingly small and performance of Linux applications is much improved over WSL 1.
BUT, apparently, accessing files stored on Windows through Linux is now piss slow.
Great, truly outstanding.
Why is this a problem? Well, I use WSL to develop c++ Linux applications using CLion, the way this works is that you set up an ssh server in WSL, which CLion uses to do compilations.
One _needs_ to have the project files stored on Windows as otherwise CLion on Windows can't access them.
If I wanted a Linux VM I would have installed one.
Urgh.13 -
I'm still on a regular basis reminded of how I might be wrong despite the absolute certainty in how obviously wrong the other person is.
Lately I've been working on setting up this API with a fairly intricate database integration. One request can lead to multiple db calls if we're not careful, so we have been polishing up the implementation to guard against ddosing ourselves and dealing with thread-unsafe concurrency.
Someone on the team could happily report that they got rid of all async use so there should no longer be threading issues. "You mean it all runs sync now?" "I guess. It works at least".
I'm just internally pulling a surrender cobra. If this was pre-dev me I would have let him and everyone know what a stupidpants he is and that I thought he had some experience in api development. But let's not make an exception to the rule; I might be wrong. I mean I'm not, but let's pretend I could be. Let's pull down the changes and maybe set up a minimal example to demonstrate how this is a bad idea.
Funny story. He got rid of explicit calls to the database entirely. When resolving data, the query is instead constructed virtually and execution is deferred until the last step. Our functions are sync now because they don't call the database, and threading isn't an issue since there's only one call per request context.
Thank god I've learned to keep my mouth shut until I can prove with absolute conclusive certainty that they are wrong. Here's to another day of not making an ass of myself. -
Last Friday a coworker told me he was planning to go to a local hackathon in the city that weekend. Then I asked him to tell me what was the app they had planned to build and he said: `Oh no, I can't tell you, a lot of ideas have been stolen this way`, I thought that was rude by not telling me but whatever.
Today, I came to work, saw him and asked how did the hackathon go and he looked at me with sadness and said: `Dude, we screw it up, we had to left the contest`, `What?` I said, `Yeah, a couple of hours before the pitch some guy came to us to review what we were doing and we presented our idea, "an app to track bus routes" and he said "there is already a local app that does that and it was the winner of a previous contest`. I told him that I knew that app and her founder, he said he wished he had told me the idea last Friday so they could pivot to something else and not leave the contest.
Conclusion: Ideas are worthless, execution is everything.1 -
Dialogflow documentation is ABSOLUTE TRASH. Trying to run the example code? It gives you a super helpful error: `Unexpected error determining execution environment`. Uh, yes, indeed. What it means? IT MEANS THAT YOU PROVIDED NO CREDENTIALS. Because, as we all know, providing no credentials should end in an error of 'determining execution environment', of fucking course.
You want to know how to provide credentials? Think again, all examples in the ENTIRE DOCUMENTATION assume that you're running the code... from their servers. Seriously. You wanna know how to authenticate your shit? NOT IN THIS DOCUMENTATION, LOSER. You want to know what exactly is happening when you're initializing your client with `new dialogflow.SessionsClient()`? Good luck, documentation is on another platform. For .NET. Because fuck you.
Also, you think you can store your auth info in a neat .env file? THINK AGAIN, because google is above such petty things as industry standards, you're getting a .json file and you're gonna like it, HAVE FUCKING FUN.
Dear google, die in a fire.

what do you think about the idea of... "pseudo-recursion"?
as in, language construct that looks basically like recursion except one detail that makes it translate into iterative execution where the "recursion" calls just add to the list of "execute in next layer" ...iterator-type variable(?)
also, if you understand what I mean and if it's not complete nonsense, any syntax suggestions that would seem most natural for you? (also for context tell me what language that syntax suggestion mostly draws from (and why))
just a bit of idle thought/idle talk, don't take it too seriously.5 -

Microsoft announced a new security feature for the Windows operating system.
According to a report of ZDNet: Named "Hardware-Enforced Stack Protection", which allows applications to use the local CPU hardware to protect their code while running inside the CPU's memory. As the name says, it's primary role is to protect the memory-stack (where an app's code is stored during execution).
"Hardware-Enforced Stack Protection" works by enforcing strict management of the memory stack through the use of a combination between modern CPU hardware and Shadow Stacks (refers to a copies of a program's intended execution).
The new "Hardware-Enforced Stack Protection" feature plans to use the hardware-based security features in modern CPUs to keep a copy of the app's shadow stack (intended code execution flow) in a hardware-secured environment.
Microsoft says that this will prevent malware from hijacking an app's code by exploiting common memory bugs such as stack buffer overflows, dangling pointers, or uninitialized variables which could allow attackers to hijack an app's normal code execution flow. Any modifications that don't match the shadow stacks are ignored, effectively shutting down any exploit attempts.5 -
vBulletin Zero-Day with Remote Code Execution. If you have a server with this, make sure it's running over 5.5.4 (or under 5.0, but that would mean you have security problems to fix).

Fuck Threads and fuck multithreading in general.

I hate it, when symfony stops the execution without any hint if you configure a dependency-injection with a non-existing class or a call on a function that does not exist.
The only reliable debugging is supported for di configuration of constructors.
It feels like, "oh. You wanna call a function or give us the classname via dependency-injection? Good luck yankee!! Better know your shit xD" -
The crazy shenanigans you can do with C++ standard libs are fascinating.
Like implementig multithreading with just a foreach, and bindings which can make member function pointers to simple function pointers, and placeholders in bindings. Also lambda functions are cool.
Something between the lines:
my_crazy_class *tmp = new my_crazy_class(...);
std::vector<type> my_array = .....;
std::for_each(std::execution::par,my_array.begin(),my_array.end(),
[&](type in){
auto fn = std::bind( &my_crazy_class::my_crazy_fnc,*tmp,_1,random_static_value);
return fn(in);
});
ps:
It's pretty much pseudocode, and please don't do things like this, it's bad for your mental health.

My vague naive extreme understanding of interview questions are on a spectrum from situation a to situation b.
But what should the industry be doing? Is the industry just going wrong blindly copying big N companies hiring process without the same rationale? (e.g. they need computer scientists able to deal with problems specific to them at their size and that often means creating new tech, unreal problem solving abilities and cuh-rayzee knowledge)
a) stupid fucking theoretical shit that some people argue you won't ever need to be doing in practice for most companies, while giving you no ability to google, leetcode hard problems kind of stuff
b) practical work similar to what you'd be doing on the job, small bugs, tasks, pair programming on site with your potential future coworkers
Lots of people hate option a because it's puzzle/problem solving that isn't always closely related to what's on the job. Whiteboarding is arguably very much a separate skill. (Arguably unless it's like a big N company where you want computer scientists to deal with specific problems that aren't seen elsewhere, and you're making new tech to deal with your specific problems.)
We could go to the extreme of Option b, but it tends to trigger people into shitfits of "NO, HOW DARE YOU MAKE ME DO REAL WORK, BUT NOT PAY ME FOR IT AT THE INTERVIEW STAGE"
That's before we get into how to execute option b whether or not it's being given as a take home assignment (which is a huge pain in the ass and time sink, among other issues) vs a few hours at the potential workplace working with some of the future potential coworkers and soaking in the work environment (you have to figure out how to take the time off then)
Is it really just poor execution overall for the wrong use cases for the majority of the industry? What should the industry be doing in which cases.
Then this is all before HR screening with shit like where they might ask for more years of swift experience than its existed. -
Hey guys!
Once again, I got a little stumped when writing one thingmajig in Python.
I am normally not a programmer (Work as sysadmin), so I don't really know all the fancy abstract ways things are done "properly", which is why I need to ask here:
I have a program, separated into parts. The "core" is a part that sets commandline argument structure (using the argparse library), loads master configuration file, sets up the main logging facility, and then proceeds to load "plugins" - python files with one or more classes that implement one specific abstract class that forces them to implement a common interface of init, run, cleanup functions.
The core then proceeds to initialize those classes, run the "run" function, and run the "cleanup" function.
If the plugin class throws a Warning, it is only logged and runtime continues. If it is anything else, the program logs it and stops.
Now, the issue is, sometimes, a user may want to continue even if a non-warning occurs.
Lets say that I am creating a user, and the user already exists. Sometimes, the program user might want to continue with further plugin execution. And what I was told was to implement specific commandline switches that force continuation of runtime despite the plugin failing.
How should I implement it? The most obvious thing is to add a specific switch for every plugin, but that is exactly what I am trying to evade. I want to have the core as abstract as possible.
Other solution I thought of is to have a file of some sort that would list extra switches to implement, then it would be up to the class to implement if it uses the switch or not (I pretty much pass the entire Namespace received from parse_args() function), but this also feels kinda hackish.
I thought about having some sort of function that the plugin could call in the core to add a new argument, but at the point that plugins start loading, the argument parser is already compiled and cannot be changed further.
Any other ideas of how to re-implement the program are also welcome! I may not do it this times, but I'd at least learn something new again.3 -

Today our PM planned to deploy in production an e-commerce based on PrestaShop.
A colleague of mine mamaged to implement everything that was necessary, and I made a small script to add random sales on random products every sunday.
We tested it several times in our environment, on multiple machines, and everything was working fine.
BUT
Today we launched the script on production server, and we was a little mistake.
"A bug? Say no more pal, I'll fix it!".
Fixed, tested on local environment, deployed and.... The first steps weren't working.
"Fatal error".
That's what I got. No exceptions, no error messages, no references.. Just "fatal error".
We spent two hours looking for the problem, thinking it was a server error that was just outputting that shitty message.
And you know what? Some fucking fat cocksucker son of a bitch thought it was an excellent idea to stop the code execution with a simple and very helpful "fatal error".
"oh, wait, there is an error here, let me print die(" fatal error"), ao the other developer will be able to find what's going on", he thought.
FUCK YOU MORON.
TL;DR: Avoid French software, they are a bounch of asshole (except some goos guy..) -

Good bye sleep 😔 -
My journey along Java continues and so I have discovered something I didn't know before:
If a subclass tries to call a method on its parent which it has not overridden, then it will call the method as if you hadn't used the keyword 'super' (and I think it will try to find it in the classpath and SDK).
Example 1:
public class SuperParent {
public String test(){
return "SuperParent";
}
}
public class Parent extends SuperParent {
}
public class Child extends Parent {
public String testChild(){
return super.test(); // same effect as test();
}
}
public class TestInheritance {
public static void main(String[] args) {
System.out.println(new Child().test()); // returns "SuperParent"
}
}
Example 2: with getClass():
public class Parent {
@Override
public String toString(){
return super.getClass().getSimpleName();
}
}
public class Child extends Parent {
}
public class TestInheritance {
public static void main(String[] args) {
System.out.println(new Child()); // prints "Child"
}
}
This here is of course a special case: .getClass() will always return the class name of its caller, so naturally in this case it returns Child and not Parent.
You would expect it to return "Parent" since you use 'super' in the overridden toString() but it returns the Class name of the Child (then there's something in programming languages such lexical scope and execution scope, which I'm not sure if it applies here).
The solution for this example is of course .getSuperClass().
Inheritance isn't always straight-forward.

Oh, there are hundreds that I've started categorizing them. They outgrew the storage capacity of my head / brain. I've tried a lot of productivity tools to organize them, but in the end, all my project ideas just remain ideas scattered somewhere unless I see it action and go like, "Hey, I had that same idea. I wonder when they got the idea. Was it before or after I had it?" In the end, I just console myself saying that for me it was only an idea in my head when those people saw it through execution and has a working product. The next step for me is to get along with them and collaborate and make that idea better rather than re-invent the same wheel again according to my idea.
Nextcloud is the biggest example of an idea that came to me and remained in my head and is still on a todo list somewhere. -

A: start it,
B: stop it on its counting completion/ manually
C: pause its execution at a number on a button click
D: resume its counting from the same number on another button click

DevOps With Ruby and Chef on FreeBSD (and Linux)
I am Ops and Dev by heart. I have always automated *nix systems long before any automation framework was invented because I am pretty lazy. Doing stuff more than once manually is just one time too often for me. Imho Ruby is a really elegant language. The same applies for the tools that are built around it. The Chef ecosystem fits into this with its own elegance and stability perfectly because the server is Erlang driven and the rest is Ruby.
Being a Linux and BSD user since the early 90s I have always loved a *nix system for it's concepts and simplicity. One command for exactly one purpose and everything is combineable like letters are combinable to words in my mother language. I have always loved FreeBSD more though. Imho it is even more focused on simplicity. Because it is a really clean approach of system design that envies a base system and keeps 3rd party separated in a clean way for example. It also values classic UNIX philosophies that most Linux distros these days abandon but which saved my life multiple times through better design and execution that also focuses alot more on stability, fault tolerance and ease of use than any Linux I have come across. The hardcore guys should read "Design and Implementation of the FreeBSD Operating System", compare the readings to the Linux way of things and see for themselves.*

[Prestashop question / rant]
Yes, it's not StackOverflow here, neither is it prestashop support forum - but I trust u people most :)
Proper solution for working with big(?) import of products from XML (2,5MB, ~8600 items) to MySQL(InnoDB) within prestashop backoffice module (OR standalone cronjob)
"solutions" I read about so far:
- Up php's max execution time/max memory limit to infinity and hope it's enough
- Run import as a cronjob
- Use MySQL XML parsing procedure and just supply raw xml file to it
- Convert to CSV and use prestashop import functionality (most unreliable so far)
- Instead of using ObjectModel, assemble raw sql queries for chunks of items
- Buy a pre-made module to just handle import (meh)
Maybe an expert on the topic could recommend something?3 -
Boy, I sure do love trying to figure out why our master and slave MariaDBs differ in their execution plans, even after running analyze tables on the whole DB.
Or rather, I really hope the two boxes didn't somehow magically desynced, cuz that would then beg a question of why, and how to prevent that from happening again.
I hate how databases are so necessary nowadays, but are probably the most complex and black box software I deal with. There's just so much to consider...1 -
Python working non-deterministic on VSCode? That just happened ... somehow, wtf??
Getting a list from a method and comparing its last element with an int value. Always worked before like a charm, didn't change a thing. All of a sudden TypeError, cannot run anymore? Restart VSCode, run again, still not running ... ?? Retry and print the element, in case I've surprisingly actually been an idiot all along ... nope, value looks in print as expected. Continue execution, suddenly condition works again. WTF just happened??? Caching, python extension bug, anything like that to blame?1 -
Persisterising derived values. Often a necessary evil for optimisation or privacy while conflicting with concerns such as auditing.
Password hashing is the common example of a case considered necessary to cover security concerns.
Also often a mistake to store derived values. Some times it can be annoying. Sometimes it can be data loss. Derived values often require careful maintenance otherwise the actual comments in your database for a page is 10 but the stored value for the page record is 9. This becomes very important when dealing with money where eventual consistency might not be enough.
Annoying is when given a and b then c = a + b only b and c are stored so you often have to run things backwards.
Given any processing pipeline such as A -> B -> C with A being original and C final then you technically only need C. This applies to anything.
However, not all steps stay or deflate. Sum of values is an example of deflate. Mapping values is an example of stay. Combining all possible value pairs is inflate, IE, N * N and tends to represent the true termination point for a pipeline as to what can be persisted.
I've quite often seen people exclude original. Some amount of lossy can be alright if it's genuine noise and one way if serving some purpose.
If A is O(N) and C reduces to O(1) then it can seem to make sense to store only C until someone also wants B -> D as well. Technically speaking A is all you ever need to persist to cater to all dependencies.
I've seen every kind of mess with processing chains. People persisting the inflations while still being lossy. Giant chains linear chains where instead items should rely on a common ancestor. Things being applied to only be unapplied. Yes ABCBDBEBCF etc then truncating A happens.
Extreme care needs to be taken with data and future proofing. Excess data you can remove. Missing code can be added. Data however once its gone its gone and your bug is forever.
This doesn't seem to enter the minds of many developers who don't reconcile their execution or processing graphs with entry points, exist points, edge direction, size, persistence, etc.2 -
Does anybody know of a Java library that you can use to parse cron expressions? I mainly want to give it a cron expressions and have it calculate its next execution time.6

#Suphle Rant 7: transphporm failure
In this issue, I'll be sharing observations about 3 topics.
First and most significant is that the brilliant SSR templating library I've eyed for so many years, even integrated as Suphle's presentation layer adapter, is virtually not functional. It only works for the trivial use case of outputting the value of a property in the dataset. For instance, when validation fails, preventing execution from reaching the controller, parsing fails without signifying what ordinance was being violated. I trim the stylesheet and it only works when outputting one of the values added by the validation handler. Meaning the missing keys it can't find from controller result is the culprit.
Even when I trimmed everything else for it to pass, the closing `</li>` tag seems to have been abducted.
I mail project owner explaining what I need his library for, no response. Chat one of the maintainers on Twitter, nothing. Since they have no forum, I find their Gitter chatroom, tag them and post my questions. Nothing. The only semblance of a documentation they have is the Github wiki. So, support is practically dead. Project last commit: 2020. It's disappointing that this is how my journey with them ends. There isn't even an alternative that shares the same philosophy. It's so sad to see how everybody is comfortable with PHP templating syntax and back end logic entagled within their markup.
Among all other templating libraries, Blade (which influenced my strong distaste for interspersing markup and PHP), seems to be the most popular. First admission: We're headed back to the Blade trenches, sadly.
2nd Topic: While writing tests yesterday, I had this weird feeling about something being off. I guess that's what code smell is. I was uncomfortable with the excessive amount of mocking wrappers I had to layer upon SUT before I can observe whether the HTML adapter receives expected markup file, when I can simply put a `var_dump` there. There's a black-box test for verifying the output but since the Transphporm headaches were causing it to fail, I tried going white-box. The mocking fixture was such a monstrosity, I imagined Sebastian Bergmann's ghost looking down in abhorrence over how much this Degenerate is perverting and butchering his creation.
I ultimately deleted the test travesty but it gave rise to the question of how properly designed system really is. Or, are certain things beyond testing white box? Are there still gaps in the testing knowledge of a supposed testing connoisseur? 2nd admission.
Lastly, randomly wanted to tweet an idea at Tomas Votruba. Visited his profile, only to see this https://twitter.com/PovilasKorop/.... Apparently, Laravel have implemented yet another feature previously only existing in Suphle (or at the libraries Arkitekt and Deptrac). I laughed mirthlessly as I watch them gain feature-parity under my nose, when Suphle is yet to be launched. I refuse to believe they're actually stalking Suphle

You know
When I first saw etherum talking about am distributed state machine i thought wow. Not very practical but NEAT. I envisioned being able to make a byte code that could be stored in transactions and run by individual clients in an async function and each step of the resulting execution and the values of managed ram would be stored at intervals so other clients could take over and execute a few more statements and compare what should always be expected results that are identical
A grand incredibly inefficient system however really neato from the theoretical computer nerd standpoint !
Boy was I disappointed lol all it is a basic contracts language but yet they state it could be like a word computer ! How ? I thought maybe if you had enough nodes participating maybe you could store registers and the like in transaction values ? Wouldn’t that be the way ?
Seems like as a word computer they’re stuck somewhere between very simplistic js and something prior to amptron in usability yet they advertised as a world computer
Am i missing something ? I mean you could create something that would translate higher level code into smal numeric statements and then send it additions values but what would it be useful for and how would you actually. Store anything ? -

Stop screen on a widget test
I have a screen which contains a button,
Pressing the button will
1. call a function showloader() to show progress indicator,
2. then awaits to perform some logic.
3. Then calls function hideLoader() to hide the progress indicator.
My question is how do I perform widget test on loader, the problem is when I do tester.pump() it gives timer error and when I do tester.pumpAndSettle() it will go ahead and call hideLoader() and the indicator gets lost and finder cannot find any widget and test fails?
Is there any way of stopping a screen on execution, so that finder can find a widget?1 -
In our Linux environment, we freeuently use a script called “shutdown.sh”. It wouldn’t be really problem if we didn’t have to switch to rootduring the execution. But damn it, it gives me heart attack when I use autocomplete and execute first thing.4
