Interview with a candidate. He calls himself "C++ expert" on his resume. I think: "oh, great, I love C++ too, we will have an interesting conversation!"
Me: let's start with an easy one, what is 'nullptr'?
Him: (...some undecipherable sequence of words that didn't make any sense...)
In my mind: mh, probably I didn't understand right. Let's try again with something simple and more generic
Me: can you tell me about memory management in C++?
Him: you create objects on the stack with the 'new' keyword and they get automatically released when no other object references them
In my mind: wtf is this guy talking about? Is he confusing C++ with Java? Does he really know C++? Let's make him write some code, just to be sure
Me: can you write a program that prints numbers from 1 to 10?
Ten minutes and twenty mistakes later...
Me: okay, so what is this <int> here in angle brackets? What is a template?
Him: no idea
Me: you wrote 'cout', why sometimes do I see 'std::cout' instead? What is 'std'?
Answer: no idea, never heard of 'std'
I think: on his resume he also said he is a Java expert. Let's see if he knows the difference between the two. He *must* have noticed that one is byte-compiled and the other one is compiled to native code! Otherwise, how does he run his code? He must answer this question correctly:
Me: what is the difference between Java and C++? One has a Virtual Machine, what about the other?
Him: Java has the Java Virtual Machine
Me: yes, and C++?
Him: I guess C++ has a virtual machine too. The C++ Virtual Machine
Me (exhausted): okay, I don't have any other questions, we will let you know
And this is the story of how I got scared of interviews29 -
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.
For updates refer the kernel tree: https://git.kernel.org/…/ke…/...

Mainly a story with some ranting sprinkled on top :)
My grandma used to refuse to turn her PC off because ONE SINGLE WINDOWS 8.1 UPDATE like 2 years ago made it so that Windows would turn the PC on by itself, nevermind it was fixed in the next update, she would simply refuse to try to turn the PC off from that point on... I never looked at the uptime but the PC was sitting on a carpet and all the fans were struggling to keep spinning, so much dust! When I asked her why it's so dusty all around the PC (the table that the PC was under was covered in a really thick layer of dust) she replied that the chambermaid comes every Wednesday to clean up the whole flat so she has no idea. I set up a camera that was recording the whole room so I could see what was going on... sure enough the chambermaid avoided anything that looked like it could have some ICs in it with a distance of at least 2 meters... When I showed the video to my grandma she was like: Yes, she is scared of electronics...
Seriously fuck me... Allright, I cleaned the whole table, carpet and the inside of PC, everything ran so quietly that I wasn't sure if I plugged the fans in.
Anyway after this I had to record the PC one whole night so I could prove to my grandma that it would not turn on by itself and she can in fact turn it off.
Fuck me... what a bad week that was...
PS: Yes, my stories do not have a point :)5 -

Every girlfriend I had broke up with me and it was not even my fault...
1. A bi cheating on her girlfriend - girlfriend found out
2. Furry cheating on her boyfriend - she felt bad...
3. Hysteric b** that did not trust me for even 1 second
4. Really nice and sweet girl... that could kill me if she did not take her antipsychotics - told me she is sorry but she wants someone older (I am older than her...) - her ex before me was 42....
To clarify: both 1 and 2 did not tell me they were cheating on someone with me... I only found out after the shit hit the fan.
I feel depressed... I just want to love someone and I want that someone to love me... that's it, I don't even want sex, I just want hugs, mutual trust and someone that I could tell anything on my mind without them judging me...30 -

Teacher: Computer settings are stored in the ROM on the motherboard.
Me: *internally* Uhm, yea, sure... and I am the pope
Me: Sorry to interrupt you but how come the BIOS settings get reset when the CMOS battery is pulled out or dies if they are stored in ROM?
Teacher: ....
Me: *internally* yea, that's what I thought, you have no clue what you are even saying - the BIOS is stored in ROM or flash memory while the settings are stored in NVRAM also called CMOS memory...10 -

"In this weeks episode of encoding hell:
The iiiinnnfamous UTF-8 Byte Order Mark veeeersus PHP!"
For an online shop we developed, there is currently a CSV upload feature in review by our client. Before we developed this feature, we created together with the client a very precise specification, including the file format and encoding (UTF-8).
After the first test day, the client informed us, that there were invalid characters after processing the uploaded file.
We checked the code and compared the customer's file with our template.
The file was encoded in ISO-8859-1 and NOT as specified UTF-8.
But what ever, we had to add an encoding check, thus allowing both encodings from now on.
Well well well welly welly fucking well...
Test day 2: We receive an email from said client, that the CSV is not working, again.
This time: UTF-8 encoding, but some fields had more colums with different values than specified.
Fucking hell.
We tell the customer that.
(I was about to write a nice death threat novel to them, but my boss held me back)
Testing day 3, today:
"The uploading feature is not working with our file, please fix it."
I tried to debug it, but only got misleading errors. After about 30 minutes, at 20 stacks of hatered, I finally had an idea to check the file in a hex editor:
God fucking what!?!!?!11?!1!!!?2!!
The encoding was valid UTF-8, all columns and fields were correct, but this time the file contained somthing different.
Something the world does not need.
Something nearly as wasteful as driving a monster truck in first gear from NYC to LA.
It was the UTF-8 Byte Order Mark.
3 bytes of pure hell.
Fucking 0xEFBBBF.
The archenemy of PHP and sane people.
If the devil had sex with the ethernet port of a rusty Mac OS X Server, then 9 microseconds later a UTF-8 BOM would have been born.
OK, maybe if PHP would actually cope with these bytes of death without crashing, that would be great.3 -

I spent an hour arguing with the CTO, pushing for having all our new products' data in the database (wow) with an API I could hit to fetch said data (wow) prior to displaying it on our order page.
He never actually agreed with me, but he finally acquiesced and wrote the migrations, API, and entered my (rather contrived) placeholder data. (I've been waiting on the boss for details and copy for three days.)
Anyway, it's now live on QA. but. I don't know where QA is for this app, and it's been long enough that i'm kind of afraid to ask.
Does that sound strange?
well.
We have seven (nine?) live applications (three of which share a database), and none of their repos match their URLs, nor even their Heroku app names. (In some of these Heroku names, "db" is short for the app's namesake, while in the rest it's short for "database").
So, I honestly have no idea where "dbappdev" points to, and I don't have access to the DNS records to check. -.-
What's more: I opened "dbappdev" on Heroku and tested out his new API -- lo and behold! it returns nada. Not a single byte. (Given his history I expected a 500, so this is an improvement, I think. Still totally useless, however.)
And furthermore: he didn't push the code to github, so I cannot test (or fix) it locally.
just. UGH.

I swear I work with mentally deranged lunatics.
Dev is/was using TFS's web api to read some config stuff..
Ralph: "Ugh..this is driving me crazy. I've spent all day trying to read this string from TFS and it is not working"
Me: "Um, reading a string from an web api is pretty easy, what's the problem?"
Ralph: "I'm executing the call in a 'using' statement and cannot return the stream."
Me: "Why do you need to return a stream? Return the object you are looking for."
Ralph: "Its not that easy. You can return anything from TFS. All you get back is a stream. Could be XML, JSON, text file, image, anything."
Me: "What are you trying to return?"
Ralph: "XML config. If I use XDoc, the stream works fine, but when I step into each byte from the stream, I the first three bytes have weird characters. I shouldn't have to skip the first three bytes to get the data. I spent maybe 5 hours yesterday digging around the .Net stream readers used in XDoc trying to figure out how it skips the first few bytes."
Me: "Wow...I would have used XDoc and been done and not worried about that other junk."
Ralph: "But I don't know the stream is XML. That's what I need to figure out."
Me: "What is there to figure out? You do know. Its your request. You are requesting a XML config."
Ralph: "No, the request can be anything. What if Sam requests an image? XDoc isn't going to work."
Me: "Is that a use-case? Sam requesting an image?"
Ralph: "Uh..I don't know...he could"
Me: "Sounds like your spending a lot of time doing premature optimization. You know what your accessing TFS for, if it's XML, return XML. If it's an image, return an image. Something new comes along, modify the code to handle it. Eazy peezy."
<boss walks in from a meeting>
Boss: "Whats up guys?"
Ralph: "You know the problem with TFS and not being able to stream the data I had all day yesterday? I finally figured it out. I need to keep this TFS reader simple. I'll start with the XML configs and if we more readers later, we can add them."
Boss: "Oh yea, always start simple and add complexity only when you need it."
Frack...Frack..Frack...you played some victim complaining to anyone who would listen yesterday (which I mostly ignored) about reading data from TFS was this monumental problem no one could solve, then you start complaining to me, I don't fall for the BS, then tell the boss the solution was your idea?
Lunatic or genius? Wally would be proud.

Like most people I needed some extra cash during uni, so I proceeded to learn CSS + Photoshop (yeah, I know). Followed by PHP and WordPress.
It can be a very shitty platform until you realize that you can stop combining plug-ins from all over the place with dubious code quality and roll your own.
Anyhow I kept at it until I was able to join a niche company doing a quite popular caching plug-in for WP (yeah, W3 Total) when I suddenly became *very* interested in anything and everything performance.
This landed me a very cozy consulting gig in the Nordics - they were using WP for an elephant-traffic website and had run into a myriad of perf issues.
Fixing them and breaking the monolith awarded me with skills in nodejs, linux, asynchronous caching among others.
I was soon in charge with managing the dev boxes for the entire team, and when the main operations dude left, I was promoted to owning the entire platform. (!) Tinkering with Linux for most of my life really came in handy here. (remember Debian potato?)
Used saltstack + aws cloudformation to achieve full parity between all environments. Learned myself some python and all various tips and tricks which in the end amounted to 90% reduction in time-to-first-byte and considerable cost savings.
By the end of the 2yr contract I had turned myself into a fullstack systems engineer and never looked back.
Lawyers not getting along resulted in us having to abandon NewRelic, so I got to learn and deploy the ELK stack as a homegrown replacement, which was super-fun.
Now I work in the engineering effectiveness department of a Swedish fintech unicorn where all languages under the Sun are an option (tho we prefer Python), so the tech stack is unlimited. Infinite tools and technologies, but with strong governing principles and with performance always in mind so as to pick the right tool for the job.
It's like that childhood feeling when you've just dumped a ton of Lego on the floor and are about to build something massive.
I guess the morale here is however disappointed you feel by your current stack - don't. Always strive to make things better, faster, more decoupled, easier to test, etc. and always challenge yourself to go outside the comfort zone.6 -
oh man... I just spent 12 hours in the zone and made what was originally meant to be made by 4 developers in close to two weeks(coding in free time)
Aaand I also drank too much coffee...
And I've done it in Node.js which I basically never used before :D ...I applied my coding standards and habits that I use when writing Java and it went like butter... ES2015 is pretty ok actually 😊1 -
I've found and fixed any kind of "bad bug" I can think of over my career from allowing negative financial transfers to weird platform specific behaviour, here are a few of the more interesting ones that come to mind...
#1 - Most expensive lesson learned
Almost 10 years ago (while learning to code) I wrote a loyalty card system that ended up going national. Fast forward 2 years and by some miracle the system still worked and had services running on 500+ POS servers in large retail stores uploading thousands of transactions each second - due to this increased traffic to stay ahead of any trouble we decided to add a loadbalancer to our backend.
This was simply a matter of re-assigning the IP and would cause 10-15 minutes of downtime (for the first time ever), we made the switch and everything seemed perfect. Too perfect...
After 10 minutes every phone in the office started going beserk - calls where coming in about store servers irreparably crashing all over the country taking all the tills offline and forcing them to close doors midday. It was bad and we couldn't conceive how it could possibly be us or our software to blame.
Turns out we made the local service write any web service errors to a log file upon failure for debugging purposes before retrying - a perfectly sensible thing to do if I hadn't forgotten to check the size of or clear the log file. In about 15 minutes of downtime each stores error log proceeded to grow and consume every available byte of HD space before crashing windows.
#2 - Hardest to find
This was a true "Nessie" bug.. We had a single codebase powering a few hundred sites. Every now and then at some point the web server would spontaneously die and vommit a bunch of sql statements and sensitive data back to the user causing huge concern but I could never remotely replicate the behaviour - until 4 years later it happened to one of our support staff and I could pull out their network & session info.
Turns out years back when the server was first setup each domain was added as an individual "Site" on IIS but shared the same root directory and hence the same session path. It would have remained unnoticed if we had not grown but as our traffic increased ever so often 2 users of different sites would end up sharing a session id causing the server to promptly implode on itself.
#3 - Most elegant fix
Same bastard IIS server as #2. Codebase was the most unsecure unstable travesty I've ever worked with - sql injection vuns in EVERY URL, sql statements stored in COOKIES... this thing was irreparably fucked up but had to stay online until it could be replaced. Basically every other day it got hit by bots ended up sending bluepill spam or mining shitcoin and I would simply delete the instance and recreate it in a semi un-compromised state which was an acceptable solution for the business for uptime... until we we're DDOS'ed for 5 days straight.
My hands were tied and there was no way to mitigate it except for stopping individual sites as they came under attack and starting them after it subsided... (for some reason they seemed to be targeting by domain instead of ip). After 3 days of doing this manually I was given the go ahead to use any resources necessary to make it stop and especially since it was IIS6 I had no fucking clue where to start.
So I stuck to what I knew and deployed a $5 vm running an Nginx reverse proxy with heavy caching and rate limiting linked to a custom fail2ban plugin in in front of the insecure server. The attacks died instantly, the server sped up 10x and was never compromised by bots again (presumably since they got back a linux user agent). To this day I marvel at this miracle $5 fix.1 -

Interesting bug hunt!
Got called in because a co-team had a strange bug and couldn't make sense of it. After a compiler update, things had stopped working.
They had already hunted down the bug to something equivalent to the screenshot and put a breakpoint on the if-statement. The memory window showed the memory content, and it was indeed 42. However, the debugger would still jump over do_stuff(), both in single step and when setting a breakpoint on the function call. Very unusual, but the rest worked.
Looking closer, I noticed that the pointer's content was an odd number, but was supposed to be of type uint32_t *. So I dug out the controller's manual and looked up the instruction set what it would do with a 32 bit load from an unaligned address: the most braindead thing possible, it would just ignore the lowest two address bits. So the actual load happened from a different address, that's why the comparison failed.
I think the debugger fetched the memory content bytewise because that would work for any kind of data structure with only one code path, that's how it bypassed the alignment issue. Nice pitfall!
Investigating further why the pointer was off, it turned out that it pointed into an underlying array of type char. The offset into the array was correctly divisible by 4, but the beginning had no alignment, and a char array doesn't need one. I checked the mapfiles and indeed, the old compiler had put the array to a 4 byte boundary and the new one didn't.
Sure enough, after giving the array a 4 byte alignment directive, the code worked as intended.

Hi everyone, long time no see.
Today I want to tell you a story about Linux, and its acceptance on the desktop.
Long ago I found myself a girlfriend, a wonderful woman who is an engineer too but who couldn't be further from CS. For those in the know, she absolutely despises architects. She doesn't know the size units of computers, i.e. the multiples of the byte. Breaks cables on the regular, and so on. For all intents and purposes, she's a user. She has written some code for a college project before, but she is by no means a developer.
She has seen me using Linux quite passionately for the last year or so, and a few weeks ago she got so fed up with how Windows refused to work on both her computers (on one of them literally failing to run exe's, go figure), that she allowed me to reinstall both systems, with one of them being dualbooted Windows 10 + Linux.
The computer that runs Linux is not one she uses very often, but for gaming (The Sims) it's her platform to go. On it I installed Debian KDE, for the following reasons:
- It had to be stable as I didn't want another box to maintain.
- It had to be pretty OOTB, as first impressions are crucial.
- It had to be easy to use, given her skill level.
- It had to have a GUI abstraction to apt, the KDE team built Discover which looks gorgeous.
She had the following things to say about Linux, when she went to download The Sims from a torrent (I installed qBittorrent for her iirc).
"Linux is better, there's no need to download anything"
"Still figuring things out, but I'm liking it"
"I'm scared of using Windows again, it's so laggy"
"Linux works fine, I'm becoming a Linux user"
Which you can imagine, it filled me with pride. We've done it boys. We've built a superior system that even regular users can use, if the system is set up to be user-friendly.
There are a few gripes I still have, and pitfalls I want to address. There's still too many options, users can drown in the sheer amount of distro's to choose from. For us that's extremely important but they need to have a guide there. However, don't do remote administration for them! That's even worse than Microsoft's tracking! Whenever you install Linux on someone else's computer, don't be all about efficiency, they are coming from Windows and just want it to be easy to use. I use Mate myself, but it is not the thing I would recommend to others. In other words, put your own preferences aside in favor of objective usability. You're trying to sell people on a product, not to impose your own point of view. Dualboot with Windows is fine, gaming still sucks on Linux for the most part. Lots of people don't have their games on Steam. CAD software and such is still nonexistent (OpenSCAD is very interesting but don't tell me it's user-friendly). People are familiar with Windows. If you were to be swimming for the first time in the deep water, would you go without aids? I don't think so.
So, Linux can be shown and be actually usable by regular people. Just pitch it in the right way.11 -
So I found this in the code:
Inet4Address.getByAddress (new byte[] {0x7f,0x00,0x00,0x01})

Can someone tell who the fuck lets morons with absolutely 0 knowledge of how the industry works go on and write articles concerning "what programming languages to learn" clickbait articles?
Look, I never looked into them. Not even when starting, I knew (out of spite) that the people that built Windows Vista were developers and then I went ahead to look what a software engineer was. I went down the rabbit hole from that and my next step at the time (I was on the local library) was to go ahead and look for programming books, C++ and Java caught my eye, so I got them two books and went down. Later on I found about JS and Python and similar shit like that and I just continued to learn. I seldom bothered to learn from internet articles because to my opinion if I needed to read documentation then I might as well fucking read it from the people that designed X technology.
some were good, some were shit, etc etc, but I never bothered to look for "what programming languages to learn" articles because I could give close to two shits about some other dickhead telling me what to learn, I have always been rather hesitant to take other people's opinion into consideration when it comes to my own learning.
BUT today I clicked on one of those articles out of curiosity.....
"Many DEVELOPER (notice the lack of proper grammar) choose to leave Visual Basic in favor of more modern frameworks like C#, Java or .NET"
Ok, so, for whatever the fuck reason Java is mentioned along C# and a fucking framework (.NET) rather than just C# for microsoft shit, is this moron talking about VB.NET at all? is he going about VB6? what? what is going on here?
Obj C is not relevant at all and should be immediately replaced by Swift since it is a modern, and stable language (never mind that each release has breaking changes on entire code bases, yeah, fuck it, just jump alltogether and ignore Obj C and the decades of stable code it has)
"Coffeescript has been replaced by the newer features of Java" <--- ok fam, you lost me here, give me your "ITPro" card please and then kick yourself repeatedly in the groin since I won't be bothered touching you, i might get some stOOpid on me.
Fuck, these articles are all over the place, from idiots like the one above, to the moron raving about pharo smalltalk shitting on every tech you use.
Just.....please bring back shit like byte magazine and shit.....please? or Linux Format, make Linux Format more popular across the board, where people who know their shit think twice before spewing their bullshit to the masses? Some fucking kid there might want to know where to start and these fucking idiots are out there just ruining shit for everything.25 -

Get told that it is too much to ask for that webpage.
Ask client to propose a price that he is willing to pay.
Never hear back drom the client.
I just don't get it... Why are people expecting that webpages are cheap? I mean, 6-7 years of experience are worth something, right? I also have to pay rent, buy food and components for my PC that break while working...3 -

This is my first rant here, so I hope everyone has a good time reading it.
So, the company I am working for got me going on the task to do a rewrite of a firmware that was extended for about 20 years now. Which is fine, since all new machines will be on a new platform anyways. (The old firmware was written for an 8051 initially. That thing has 256 byte of ram. Just imagine the usage of unions and bitfields...)
So, me and a few colleagues go ahead and start from scratch.
In the meantime however, the client has hired one single lonely developer. Keep in mind that nobody there understands code!
And oh boy did he go nuts on the old code, only for having it used on the very last machine of the old platform, ever! Everything after that one will have our firmware!
There are other machines in that series, using the original extended firmware. Nothing is compatible, bootloaders do not match, memory layouts do not match, code is a horrible mess now, the client is writing the specification RIGHT NOW (mind, the machine is already sold to customers), there are no tests, and for the grand finale, the guy canceled his job and went to a different company. Did I mention the bugs it has and the features it lacks?
Guess who's got to maintain that single abomination of a firmware now?1 -
My first contact with an actual computer was the Sinclair ZX80, a monster with 512 bytes of ram (as in 1/2 kbyte)
It had no storage so you had to enter every program every time and it was programmed in basic using key combinations, you could not just write the commands since it did not have memory enough to keep the full text in memory.
So you pressed the cmd key along with one of the letter keys and possibly shift to enter a command, like cmd+p for print and it stored s byte code.8 -
Dear ESLint,
- you convinced me to put a space between function() and {
- you convinced me to use single quotes for strings in place of double quotes
- you convinced me to put a space between inline operators
- you had me when you said that trailing spaces shouldn't compare in my code
- you said to put semicolons at the end of each instruction, and I thought it wasn't a so bad idea
BUT NO FUCK OFF NO NEVER I WON'T NEVER PUT A FUCKING TRAILING COMMA IN THE END OF JAVASCRIPT OBJECT IT'S MEANINGLESS UGLY A WASTE OF A FUCKING BYTE.
WHY THE FUCK I SHOULD TYPE var obj = {a: 'some text',} INSTEAD OF var obj = {a: 'some text'} WHY WHAT'S THE MEANING OF THAT FUCKING COMMA9 -
I have a habit of leaving random TODOs in random files of projects I work on. Then, when I come back to work on the projects I display a list of all TODOs and try to implement them only to find out that I already implemented everything and forgot to delete the TODOs, on the positive side I feel like I accomplished a lot without actually doing anything 😂😂😂

Buffer usage for simple file operation in python.
What the code "should" do, was using I think open or write a stream with a specific buffer size.
Buffer size should be specific, as it was a stream of a multiple gigabyte file over a direct interlink network connection.
Which should have speed things up tremendously, due to fewer syscalls and the machine having beefy resources for a large buffer.
So far the theory.
In practical, the devs made one very very very very very very very very stupid error.
They used dicts for configurations... With extremely bad naming.
configuration = {}
buffer_size = configuration.get("buffering", int(DEFAULT_BUFFERING))
You might immediately guess what has happened here.
DEFAULT_BUFFERING was set to true, evaluating to 1.
Yeah. Writing in 1 byte size chunks results in enormous speed deficiency, as the system is basically bombing itself with syscalls per nanoseconds.
Kinda obvious when you look at it in the raw pure form.
But I guess you can imagine how configuration actually looked....
Wild. Pretty wild. It was the main dict, hard coded, I think 200 entries plus and of course it looked like my toilet after having an spicy food evening and eating too much....
What's even worse is that none made the connection to the buffer size.
This simple and trivial thing entertained us for 2-3 weeks because *drumrolls please* none of the devs tested with large files.
So as usual there was the deployment and then "the sudden miraculous it works totally slow, must be admin / it fault" game.
At some time it landed then on my desk as pretty much everyone who had to deal with it was confused and angry, for understandable reasons (blame game).
It took me and the admin / devs then a few days to track it down, as we really started at the entirely wrong end of the problem, the network...
So much joy for such a stupid thing.18 -

I love open source and all that fun stuff but I am very unimpressed by having to use GNU/Linux based OS after the last fuck up... the lack of games, stuff that actually works, the almost constant need to compile something and the need to have DDG open at all times because something broke. I mean why the fuck do I need to install libcurl3:i386(for 32 bit programs and games) if there is already libcurl4 and why the actual fuck does it conflict?!... Why the fuck do I need to glue together and compile drivers for my printer?! And they only have "beta support" so like half of the functions that the printer would normally have... Why the fuck don't any games work? Witcher 2? Nope, you click launch and the launcher just closes itself. osu!lazor? Nope, the game will run but only as a process in the background, no window will open no matter what I do. StarCraft: Brood War? Nope, Wine hates the battle.net client and running it in a VM is a really bad idea, the game flickers like crazy... Any other games? Pretty much out of luck... I would really like to play KCD but I doubt it would be playable...24

Context: I (among other things) manage some servers for my students' club so I have first-hand information about anything network or server-related that happens. We basically run a big enterprise network and we allow devices to connect if a person has paid their membership and the device's MAC address (be it wireless or ethernet) is recognized by our switches/aruba controllers.
Story: So today a first complaint about "the wifi not working" came in because of Android 10 and its MAC randomization. We deal with MAC randomization on Windows laptops and PCs but I think it is disabled by default so we almost never get this type of complaint.
It took one of the other guys probably 5 minutes to figure out how to disable it... only to discover it is a per-network setting.
The actual question: If there are any network administrators here on devRant - how do you deal with this MAC filtering vs MAC randomization issue?7 -

Fuck this shit! Roommate just barged in at 3:30AM, his gf in tow. They went to bed like I am not here and he is snoring like a chainsaw. I never understood how can she sleep next to him while he snores like that. I have earplugs and active noise cancelling headphones on. I can still hear that motherfucker loud and clear. How the fuck is she not awake?!
But more importantly, 50% of this fucking room is mine, what makes him think he can just have his girlfriend over while I am here is beyond me. Like, sure, if I am not here go ahead but when I am here I would like some privacy, I guess the plank wall that I made in the middle of the room is not an obvious enough clue that I want privacy and I don't want to be disturbed :-/
Can't wait to have enough proof of his bullshit to get the block manager to throw him out.
Edit: To add to the snoring problem: I had a girlfriend who would snore, less than my roommate but still loud enough that I was awake the whole night when I went to sleep at her place... I HATE SNORING ... And when I went home for some holidays and my brother snored even for a second I kicked him off of his bed (because why not, he is an asshole to me like 99% of the time - and so am I to him :D //sibling love//)12 -

Dont blame me for making Minecraft plugins, but holy shit i really hate stairs right now.
Im modifying some old code of mine to add extra features, and i just need to be able to rotate stairs 90, 180 and 270 degrees, then im past this bump.
Stairs get their direction based on a byte value that makes no fucking sense to me.
North = 3
West = 1
East = 0
South = 2
Ive been drawingto see if that made me go "oh like that", checking if the bits of each value had a system, and now im here.
Titshit.
I dont know who made it like this, but i really dont want to make some static switch or if/else statement to process this directional trash. I want it flexible.
If you spotted a system to the numbers, please mail me a rock, and then tell me how i fix this.12 -

Try these few steps!", you open the page and they proceed to put 10 pages of non-sense in front of the actual steps - every single fucking article. DO THESE PEOPLE HAVE THE IQ OF A CENTIPEDE?!! After 12 minutes of this shit that I had to listen to I just said fuck it and somehow managed to throw myself off the bed and onto the ground - where I landed on all four and was somehow able to stand up and grab some Theraflu forte(apparently paracetamol is the best cure for jammed neck muscles and I know that there are 1000mg of it in one packet of theraflu) from my cardboard box full of meds.4 -
Just gonna leave this here because I am too lazy to write a proper article for my website:
If anyone is trying to create a Vue.js website with Node.js backend do NOT use express-vue, it is unnecessarily complicated and broken. Instead use this method I found.
You will need:
- IntelliJ IDEA / WebStorm / other IDE supporting multiple modules per project and tasks
- Nodejs and npm
- vue-cli
Step by step:
1. Create new empty project
2. Add your frontend module using vue-cli generator
3. Add your backend module using Express generator
4. Run npm build in your frontend module once
5. Move or remove public folder in your backend module
6. Create a symlink from your backend module root called public pointing to dist folder in your frontend module root
7. Make sure to add "Run npm build" from frontend module to your "bin/www" task (default task for Express module)
8. Enjoy developing your REST API in Node/Express and your frontend in Vue.js with single-file components and it being served by the same server that is providing the backend.
(Since they are separate modules and you are not mixing webpack and Node/Express you can add ts-loader, stylus-loader, pug-loader or any other loaders without screwing anything up)
For deployment you just need to copy the contents of dist into public on the server. (and not upload the symlink)6 -

WHAT THE ACTUAL FUCK!!! LibreOffice Impress is a complete shit!! I am all about open source and such but this shit just sucks, moving elements around a frame snaps them to some grid, however when you paste an element from other frame it will have a different grid!!! This motherfucker has got an ALT function that will allow you to move the element more precisely but it only works seldom and it hates it when I try to use the fucking arrow keys - it even crashed once when I tried it. AND WHEN YOU FUCKING COPY A TABLE FROM ONE FUCKING FRAME TO ANOTHER MOTHERFUCKING FRAME, DELETE A FEW ROWS AND THEN COPY THE FREAKING TABLE BACK IT WILL HAVE MAGICALLY DIFFERENT DIMENSIONS BUT JUST EVER SO SLIGHTLY, BECAUSE FUCK THE USER, RIGHT??!!!

Hiii devRanters, I have a TypeScript question for you...
How do I dynamically import classes?
I have a class like this:
export default class Foo implements Bar {
...
....public getName(): string {
........return this.name;
....}
}
and then I have another file with this:
import(`./class-cmd/${file}`).then((command) => {
....winston.debug(command);
....winston.debug(command.getName());
});
the first command spits out something like this:
debug: default=class Foo {
....constructor() {
........this.name = "foo";
....}
....getName() {
........return this.name;
....}
}
and I would expect that the second command will work, however it throws this:
UnhandledPromiseRejectionWarning: TypeError: command.getName is not a function
Any idea what I might be doing wrong?18 -
Just a quick rant on JavaScript,
So there’s a lot of people hating javascript, and while not a long time ago i was part of them, but I changed my opinion a little.
I think JavaScript is a great way to deal with website programming as it is quick and efficient, but I would not say to program directly on it, use a js-compilable language (CoffeScript, TypeScript, Kotlin(I think), etc.), but then you might say: “Well, no need for js then, compile it in byte code”. That would break the point of how I see web design/dev. The main intent behind webpages is to have an easy and fast way to send code to other computers to render them, that’s why it is interpreted: “Easy to send” and “*All* computers can handle it” with the proper browser. You need to be able to change the way the website is rendered and/or works sometimes, for diverse reasons like copy/pasting data, make it render properly or use plugins/add-ons to change that code to suit your needs.
I think js should be kept as a “readable byte-code”, so that means: {
Keep comments when compiling the js-compilable code,
Add standardized machine-readable comments that will indicate to smart code viewers how to show a particular thing (Like have a higher-end function compiled in js shown as a minimized code with explanations of the function)
Keep it nicely formated and don’t obfuscate (coz that’s annoying)
Etc.
}
So you bypass the quirks and all that pesky js stuff, while keeping it’s good sides.
-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-
Part 2:
Web design for non-web:
Ok so things like node.js, electron, react-native and all that stuff; I won’t say they’re bad but...
Why we have this is because web designers wanted to make desktop apps and were like “Hey! Making web pages is easy! Let’s port it to desktop”, the problem is: Web technologies were made to work on a restricted canvas, aka a browser. It’s good on web for reasons mention earlier and more. But it’s not on desktop! You’re trying to push it outside of those boundaries. It’s difficult to make it break that canvas and go outside, make something that really works! For social media clients and that kind of stuff that you want to make a little more inclusive, yes! it’s a great idea (hello devrantron ;), but not if it’s an exact same copy of the website, just use the website. But for things that are supposed to really make use of YOUR computer; no!
I see those PWA (progressive webapps aka mobile app, but it’s an offline website”), I stand for the same positions, social media and those sort of things: yes, great idea! Games? 🤢.
I have way more to say but I have difficulties to remember them while reading, so feel free to comment your thoughts

"Our Data Service comes PRE-P0WN'D"
Those SHIT-FOR-BRAINS data service providers GLOAT that their data can be natively integrated into most BI platforms, no code required.
How? Because they will EXPOSE THE ENTIRE FUCKING THING ON THE INTERNET.
LITERALLY.
UNAUTHENTICATED URL WITH THE ENTIRE DATASET.
STATIC. WON'T EVER FUCKING CHANGE.
NO VPN REQUIRED. NO AUTHENTICATION HEADERS. NO IN-TRANSIT ENCRYPTION.

BLOODY BYTE BUTTS, BATMAN! IT IS A FUCKING UNAUTHENTICATED URL THAT DOES NOT REQUIRES RENEWAL NOR A VPN, IT WILL LEAK EVENTUALLY!
That is the single fucking worst SELF-P0WN I have ever seen.

I really hate PHP frameworks.
I also often write my own frameworks but propriety. I have two decades experience doing without frameworks, writing frameworks and using frameworks.
Virtually every PHP framework I've ever used has causes more headaches than if I had simply written the code.
Let me give you an example. I want a tinyint in my database.
> Unknown column type "tinyint" requested.
Oh, doctrine doesn't support it and wont fix. Doctrine is a library that takes a perfectly good feature rich powerful enough database system and nerfs it to the capabilities of mysql 1.0.0 for portability and because the devs don't actually have the time to create a full ORM library. Sadly it's also the defacto for certain filthy disgusting frameworks whose name I shan't speak.
So I add my own type class. Annoying but what can you do.
I have to try to use it and to do so I have to register it in two places like this (pseudo)...
Types::add(Tinyint::class);
Doctrine::add(Tinyint::class);
Seems simply enough so I run it and see...
> Type tinyint already exists.
So I assume it's doing some magic loading it based on the directory and commend out the Type::add line to see.
> Type to be overwritten tinyint does not exist.
Are you fucking kidding me?
At this point I figure out it must be running twice. It's booting twice. Do I get a stack trace by default from a CLI command? Of course not because who would ever need that?
I take a quick look at parent::boot(). HttpKernel is the standard for Cli Commands?
I notice it has state, uses a protected booted property but I'm curious why it tries to boot so many times. I assume it's user error.
After some fiddling around I get a stack trace but only one boot. How is it possible?
It's not user error, the program flow of the framework is just sub par and it just calls boot all over the place.
I use the state variable and I have to do it in a weird way...
> $booted = $this->booted;parent::boot();if (!$booted) {doStuffOnceThatDependsOnParentBootage();}
A bit awkward but not life and death. I could probably just return but believe or not the parent is doing some crap if already booted. A common ugly practice but one that works is to usually call doSomething and have something only work around the state.
The thing is, doctrine does use TINYINT for bool and it gets all super confused now running commands like updates. It keeps trying to push changes when nothing changed. I'm building my own schema differential system for another project and it doesn't have these problems out of the box. It's not clever enough to handle ambiguous reverse mappings when single types are defined and it should be possible to match the right one or heck both are fine in this case. I'd expect ambiguity to be a problem with reverse engineer, not compare schema to an exact schema.
This is numpty country. Changing TINYINT UNSIGNED to TINYINT UNSIGNED. IT can't even compare two before and after strings.
There's a few other boots I could use but who cares. The internet seems to want to use that boot function. There's also init stages missing. Believe it or not there's a shutdown and reboot for the kernel. It might not be obvious but the Type::add line wants to go not in the boot method but in the top level scope along with the class definition. The top level scope is run only once.
I think people using OOP frameworks forget that there's a scope outside of the object in PHP. It's not ideal but does the trick given the functionality is confined to static only. The register command appears to have it's own check and noop or simply overwrite if the command is issued twice making things more confusing as it was working with register type before to merely alias a type to an existing type so that it could detect it from SQL when reverse engineering.
I start to wonder if I should just use columnDefinition.
It's this. Constantly on a daily basis using these pretentious stuck up frameworks and libraries.
It's not just the palava which in this case is relatively mild compared to some of the headaches that arise. It's that if you use a framework you expect basic things out of the box like oh I don't know support for the byte/char/tinyint/int8 type and a differential command that's able to compare two strings to see if they're different.
Some people might say you're using it wrong. There is such a thing as a learning curve and this one goes down, learning all the things it can't do. It's cripplesauce.12 -

Teach things properly, most teachers are confused and they start throwing keywords at even more confused students who then have no clue what they are doing and they then ask me to do their work for them showing me their unindented(well... kinda, they all seem to fight with the IDE, which is trying to properly indent their mess, for some reason), teachers think that Turbo Pascal is the way of life and that it is used everywhere(one teacher tried to tell me that Pascal is used in the stock market and in modern operating systems - U wot m8?! how high are you right now) and they don't teach user input sanitization and type checking, they stare at you like you are the fucking satan when you dare to use objects, collections and abstraction because they are scared to death of that stuff... and then they think 60 minutes is enough to teach HTML, CSS, JS and PHP in one go(which they even don't know properly - the teacher that made and maintains the school's website is probably stuck in 1998 judging by the design and functionality of the website and his clothes) and they then send absolutely clueless students to compete in a web design competition (and then they get angry at the judges for giving the students 0 points)6

Let me introduce you to sys. admin + network admin + teacher at our school... She gave us "materials" to study for our school-leaving exams (called matura here - wiki that shit) so I looked at it and just had to comment everything that's wrong (and that's only the first paragraph)...
Apart from making utterly useless documents she also likes to think she is the best in the world and what she says is right and everyone is wrong. Networks that she builds crash 8 times a month, she can't install proper drivers and believes that open source and GNU/Linux is evil. (She also lives by herself, is around 48 years old, is a lesbian(not that it is a bad thing - just for context) and got one brilliant teacher who actually knew what she was saying and doing fired because she broke up with her)
Thinking about it - no wonder my classmates are all so confused and stressed... she can't teach and says bullshit like printers work with the RGB color space and when confronted she would shout that there are no printers that use CMYK, she has never seen one so they do not exist. (only to proceed changing CMYK ink cartridges in the printer)... I mean it's good for me because I get to teach pretty girls programming and informatics but I am sorry for the boys... Unfortunately I don't have the patience to teach someone programming and informatics unless they are a girl and I see a chance to evaluate that person's qualities to be a girlfriend.

This is a fucking nightmare! All this motherfucking work for nothing! I think I am going to cry... I mean we still have all the hardware and stuff but we can't do anything with it because is was build for one fucking task and noone would probably buy it because how specific the task that it's made for is. I mean I technically only own the software... anyone interested in buying an Android app that connects to a sensor (that counts stuff) via BLE, processes data from the sensor and uploads it to a database? It can also upload new firmware to the sensor, set basically any parameter and get all kinds of telemetry from it... can't really say what does this sensor count or anything about the hardware (I am not sure if I am allowed to brcause I don't own it - I only got to work on the firmware and the app)3 -

- you magically verify that token
- you respond with { credentials } //magic

- you freak out and write your own authentication scheme only to find out that you cannot read payload of POST requests in the authenticate method
- you get angrier and depressed and write a rant

Seriously, fuck the Czech Post... China Post was able to figure out the fastest route and load the package onto a plane in 3 freaking days while I can only guess the package was in Czech Republic on 15th of April and it spent 8 days at the customs and now it is sitting somewhere in a warehouse that is literally around the corner from where I live (less than 1km) and I can't just go and pick it up from there so that I don't have to wait for them to finally wake up after half a month and deliver it because there is fucking no one there. How the fuck are they not going bankrupt?!! If I was sending something and it took them one month to notice it I surely would not be using their services again... And their tracking system is the worst I have ever seen. Even compared to Slovak Post the Czech Post is a steaming pile of shit.

NULL and '/0' are two different things. NULL is a null pointer. '/0' is a null byte. C handles those two differently enough to introduce some interesting issues. Helped a friend debug his code, execvp() was freaking out because he had tried to terminate his argv array with a null byte instead of a null pointer. As far as the system was concerned, that doesn't mean anything more than "oh look there's no string here." Big big difference.3

I got to work on this project written in PHP that is literally unsalvageable so I will need to redo it from scratch, it's an e-commerce/social network mix that allows you to resell your clothes and I will have to work with PHP-only server-side so I was looking for a JS framework that has all these cool features like Angular but does not require node.js and I stumbled upon React and Vue and I can't decide between them.

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.
Arent ideas like this what lead to the randomization of jump addresses in modern architectures?8 -

A few years back I was still using a CRT screen and I used to degauss it quite often as a result of having my speakers right next to it. Nowadays I use an LED screen but now I started getting this kind of "degaussing" effect where my vision shakes and waves and I get it quite randomly when looking at lights of different frequencies. (Like the Sun and my phone's screen) It only lasts like 2 seconds at most but I'm wondering if someone has the same problem as me and I would be quite interested to know if this has been caused by the CRT screen or something else.3

This is the EASIEST web project setup and test that I've ever tried and that let me showcase something from my machine to the entire world! :')
Great job Microsoft; can't wait to try the cross-platform of this open standard. -
Ideas I've had over the years that could pan out and be useful:
SMS-DB: Stands for SMS-Data Burst. Used to allow those with low cell signal or no data plan to transfer data between a phone and some client via the standard SMS text space. Would be slow, but would act kinda like dial-up over SMS (as mobile lines are compressed on all service levels, even LTE, so traditional dial-up wouldn't work!) I have a general idea on how packets would be laid out, but that's about it so far...
everything2PNG: Allows one to transpose any file's data into a PNG with a 3 byte per pixel (full color RGB), which allows for a "compression" of sorts (about 91, 93% on preliminary tests) AND allowing further, more efficient compression of the resulting file. (Plus... it's just kinda cool to see files transposed as PNGs.) I actually have a simple transposer to go to PNG, but can't yet go back. Large files (around 600MB) use upwards of 4GB with efficient paging and other optimizations via NumPy so far, so it's not *viable* yet, but it's coming along nicely.
RPi-GPIO Interconnection Bus: A master/slave or round robin method to allow for Raspberry Pis to communicate using GPIO, which can help free up network bandwidth in RPi cloud computing clusters. At most, this'd allow for 4 bits used for pushing to the GPIO "bus", and 4 bits used for pulling from the "bus". 8 pins total are usually unused minimum, so either 3 or 4 pins for upload, 3 or 4 for download, and potentially 1 or 2 for commands, general non-data communication, etc. I made a version of this concept using Round Robin for a client, but it was horribly slow. (I also don't have distribution rights for the code, so i'm working from scratch.) Definitely doable. -

But why the heck does the PC that runs them reboot every time the bus hits a bump or a pothole in the road and most of all why does it run a full-blown Ubuntu 10.04?!! I mean it's still better than running Windows but just why... why are they even using PCs... A Raspberry Pi would be more than enough for the job...4

C++ is the building blocks for many high-level programming languages, and since 1984 its first appearance in the markets the C++ core committee developers have introduced its 4 new versions which are C++03 (ISO/IEC 14882:2003 second edition), C++11 (third edition), C++14 (fourth edition) and C++17 is the fifth edition. With each new version, developers introduced new features, libraries and APIs in it.
C++ introduced as the extension of C programming language which made C++ as a compiled programming language, which means the developer required a C++ compiler to translate the C++ code to its equivalent machine or byte language, so the Operating system of the computer can execute the program.
There are various C++ compilers in the market and most of them are open source and free to use, however conventionally when we say C++ compiler, we basically talk about GCC which stands for GNU Compiler Collection.
What is GCC?
GCC stands for GNU Compiler Collection, and it is a collection of programming compilers which induce C, C++, Objective-C, Fortran, and some versions of Java. The first version of GCC introduced in 1987 and it was also known as GNU C compiler which became the standard compiler for C programming language, in that same year GCC also provided Compiler support for the C++ programming language.
Now GCC has various versions and each version give specific support for C++ versions, by now if we look at all the versions of GCC, we have a stable GCC for every version of C++, but there are some exceptions with C++11.
C++11:
C++11 introduced as the 2nd update version of C++, it suffixes 11 because it released in 2011 or because on August 12, 2011, ISO gives official approval to it. Formally C++11 known as C++0X because developers were expecting the new update released in 2010, but with its release in 2011, the core committee developer of C++ changed its name by C++0X to C++11.
C++ 11 replaced the old version of C++03, and it also brings many new features for the C++ developers. The main aim of designing C++11 to stabilize and maintain the backward compatibility of new C++ version with the C+98 and C programming language and that’s become the main reason why core committee developers only introduced new features in the old standard library rather than extending the core language.
GCC does not give Full Support to C++11:
GCC version GCC 4.8.1 purpose the first feature-complete implementation of the C++11 standard, however, the 4.8 and 4.7 does not give the full support for the C++11. The current version of GCC provides the major support for all the standard features of C++11 but if you are using the GCC 4.8 or 4.7 versions then your GCC only provide you with the experimental support for the C++11.
To use the Experimental support of GCC you need to enable it first before you compile or run you C++ 11 version code.
use code std=c++11 or -std=gnu++11 to enable the experimental support for C++11.17 -
I had a splash of inspiration. I would like to develop a method for analyzing unknown bitstreams of data. The method would involve determining the format of the data by trial and error machine learning algorithms. This would allow determining data types and byte formats and meanings of streams of data. Could be useful in data forensics. I would call the method: heuristic translation machine learning. I am currently developing code that does this. It will be fun to learn about reinforcement algorithms.5

Ranters, I need help
Does anyone know how can I run something as a systemd service and still have access to the "console" - the input and output of the program, when I need it?
(It is a minecraft forge server and there are multiple people managing the physical server and one of them managed to corrupt the map yesterday by rebooting the machine without stopping the minecraft server... so there comes the need for a service so it can shut down before the machine reboots... but I also need the access to the console of said minecraft server because sometimes when some modded items are misbehaving the rcon will stop responding while the console still works)
Edit: currently I am running the minecraft server in a detached screen (ddg "screen linux" if you don't know what I am talking about)5 -
man if i could figure out how to do stuff and had the money to do stuff i'd be dangerous as fuck, but as of now i can only posit questions... it sucks.
Examples:
- What do modern browsers/crawlers do when hit with, say, an "HTTP 450 Blocked by Windows Parental Controls" or an "HTTP 374" status code?
- What happens if I do <xyz minor edge case thing> on <system?> (just use your imagination, this happens for every edge case i can think of for every system and the list wouldn't fit in a few megs' worth of half-byte ASCII, much less *here*)
- What if I made like a board to fuck with busses while systems were on? Press a button and for like five bus clock cycles pins like 6 and 7 are shorted? That sort of thing. As for system/bus types, *literally any* (old consoles with expansion ports, PCI/-e/-X/whatever, southbridge, etc.)
- What if I did <filetype> shenanigans by doing <something indescribably horrible> to this file? How do things react?3 -
What we will miss, if he really softens:
In fact, if the reason is stated as "it makes debugging easier", then I fart in your general
direction and call your mother a hamster.
In short: just say NO TO DRUGS, and maybe you won't end up like the Hurd people.
Of course, I'd also suggest that whoever was the genius who thought it was a good idea to read things ONE F*CKING BYTE AT A TIME with system calls for each byte should be retroactively aborted. Who the f*ck does idiotic things like that? How did they not die as babies, considering
that they were likely too stupid to find a tit to suck on?
Gnome seems to be developed by interface nazis, where consistently the excuse for not doing something is not "it's too complicated to do", but "it would confuse users".
I think the stupidity of your post just snuffed out everything
I think the OpenBSD crowd is a bunch of masturbating monkeys, in that they make such a big deal about concentrating on security to the
point where they pretty much admit that nothing else matters to them.
That is either genius, or a seriously diseased mind. - I can't quite tell which.
Christ, people. Learn C, instead of just stringing random characters together until it compiles (with warnings).
"and anybody who thinks that the above is
(a) legible
(b) efficient (even with the magical compiler support)
(c) particularly safe
is just incompetent and out to lunch.
The above code is sh*t, and it generates shit code. It looks bad, and
there's no reason for it." -
I'm building a script parser to make mods for a game I like. The first step is to write an importer.
The documentation is nonexistent and I'm delving into byte manipulation, which I'm not familiar with - at all. I'm porting existing code from Java to C#, and everything is similar but different enough that I can't always just to a 1:1 transfer.
I get everything working, cleaned up and split into classes so I can write the exporter.
I do an import and the file won't parse. I try all previously know working files and still no good. I clean, rebuild, clean rebuild, run, debug, restart my computer, clear my cache, clean, rebuild. No good.
IT WAS WORKING 5 MINUTES AGO
Proceed to revert to every version from the last hour. No dice.
I was in the wrong folder the whole time.
Navigate to the proper folder, open the filename I know to be good and bingo, works like a charm.
The same project caused me headaches because I had a "== -1", when it should have been "== 1". Between my inexperience with byte manipulation and my untreated astigmatism, I was nearly sent to the shadow realm fixing that.3 -
So how does an experienced programmer break his own code in a such a terrible manner.
And why would someone try to make me embrace a bogus thing I KNOW doesn't work to make sure its broken ?
See this is what I hate about this shit.
No programmer would make the mistake that was made. They converted all their classes that interpret STRING VALUES using a parse to BitConverter.
(The input is a byte array) for like, ALL THEIR CLASSES.
Again this seems fucking intentional.
Instead of letting it remain a goddamn class that handed around an open file stream with a binaryreader around it which was simple, they tried some fucking fancy shit and throw readonlyspan<byte> at a read method which is where the code WILL fuck up ! wtf is wrong with you fucking dumb bastards ? IF YOU DONT WANT THE CHOMS GETTING AHEAD SHOOT THEM JESUS CHRIST !
Maybe this is some special interests shit to make sure ArcGis remains the dominant gis package and no ordinary lowly programmer can have a reader to get started with their own manipulations.
YOu fucking bastards screwed up the world and i want to eat your fucking hearts from your chests and wear your fucking scalps and ears on a fucking necklace while burning down your fucking houses !
AND FIX THAT GODDAMN STEAM RELEASE VALVE !!!1 -
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 ?
