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.

What is the most ridiculous over-the-top "startup" thing you've been the victim of as a developer?
Alternatively, what kind of weird startup luxury would you absolutely love to have at your company?
For me, at various companies I've worked at/visited:
1. Hammocks & fatboy beanbags. Current employer has a "Netflix & Chill" corner with nice couches, and a small gym. I have encountered isolation/flotation tanks at the office of one of our partners... which is cool, but over the top in my opinion.
2. A fully automated aquaponics garden in the lunchroom. Was awesome, until some fish died and started to rot.
3. One hoverboard per employee, at previous employer. I splashed hot chocolate milk in an arc over three desks. A coworker broke his ankle while watching me spill chocolate milk.
4. Daily scrum standup meetings, on socks, in a big bouncy castle. Not kidding. Fucking ridiculous... (but secretly fun). That employer also had spiral slides between all floors, a tiny half-pipe with tiny skateboards, and someone who rode a unicycle way too much. It was a fucking circus. Stuck in the office of a Fintech company.
5. Soldering bench (at my current company), with drawers full of breadboards, servos and electronics components. Completely unrelated to my work, but it was my idea. It's just great to build a simple kits together with another random coworker while brainstorming platform features & refining specs... much better than meetings with bullshit slides.
6. Unlimited energy drink. Developed a serious caffeine habit (15-20 cans a day), and almost got a stomach ulcer. Not beneficial to employee health.
7. I really do love working from home + unlimited holidays. Just being able to honestly say "fuck you guys, I'm gonna get drunk and play games today", and at other times working until 4am and sleeping in the next day, or taking a week to work in a park in Rome... It makes work truly feel like my favorite hobby. Combined with a good sprints and curious/ambitious people, you can easily track productivity anyway.19 -
Woohoo! 32k achieved!!! Finally I can post some new rant without risking some sudden overshoot 😁
So putting celebrations aside for a minute, a while ago I've noticed a tingle when I stroke my finger across metal areas of my tablet, or the sides of my phone (which probably has metal near it too) while it's charging. And it's been bugging me ever since.
Now, some things to note are that it only happens when my feet are touching the ground though slippers, and that the frequency is so low that I can actually feel the tingle when I slide my finger across the material. This to me at least seems like electricity flows through me into ground, and touching the ground directly provides a path so easy for the electrons to run away that I don't feel it at all. But if I lift my feet off the ground entirely, I just get charged up and after that, nothing else happens.
So those are my ideas. The answers on the subject on the other hand.. absolute cancer. Unsurprisingly, most of them came from Apple users. Here's some of them.
https://discussions.apple.com/threa...
- I've not noticed it, but if you're concerned bring the phone to Apple for evaluation.
- Me too facing same problem.. did u visit apple care?
And one good answer at least...
- google emf sensitivity, its real. You are right, there is a small current flowing through your body, try to limit your usage. The problem with this issue is those who aren't affected (lucky ones for now) will tell you these products are 100% safe. To a degree they are, i used my ipod touch for about 2 years straight vwith virtually no symptoms. then the tingling started and it gets worse.You will get more sensitive to progressively less powerful things. I dont want to scare you but just limit your usage like i didnt do 🙂
Overall that discussion was pretty good actually, aside from "bring it to the Genius Bar, they'll know for sure and not just sell you another unit". But then there's Reddit.
https://reddit.com/r/iphone/...
- Ok, real reason is probably that the extension cord and/or outlet is probably not grounded correctly. Either that or you are using a cheap knockoff charger.
Either use a surge protector and/or use the authentic Apple Charger.
- It's not the volts that hurt you, it's the amps
- I think you are in deep love with your phone. That tingling sensation is usually referred to as "love" in human language.
- Do less acid, I would advise.
Okay, so that's the real cancer. Grounding issue sounds reasonable despite it being wrong. Grounding is actually not needed when your charging appliance doesn't have any exposed metal parts. And isolation from high voltage to low voltage side actually happens through things like routering holes into the PCB, creating spark gaps, and using galvanic isolation through things like optocouplers. As for a surge protector? I'm using them to protect my PC and my servers, but the only purpose they serve is to protect from.. you guessed it.. voltage surges, like lightning bolts hitting the grid. They don't do shit for grounding or reducing this tingle! What a fucking tool.
It's not the volts that kill, it's the amps.. yeah I'm sure that the debunking of that is easy to find. Not gonna explain that here. And the rest of it.. yeah it's just fucking cancer.
Now what's the real issue with this tingle? It's actually a Class-Y rated (i.e. kV rated) capacitor that's on the transformer of any switch-mode power supply, including phone chargers. If memory serves me right, it helps with decoupling the switching noise and so on. But as it's connected to the primary side of the transformer, if the cap is sufficiently large and you are sufficiently sensitive, it can actually cause that tingle by passing a fraction of the mains electricity into your body. It's totally safe though, as the power that these caps pass is very small. But to some, it's noticeable.
Hope you found this interesting! And thanks a lot for bringing me to 2^15. I really appreciate it ♥️14 -

There are 3 types of questions.
Type 1 is a question that can easily be answered and mostly appears as the first result in Google.
Type 2 is a question that can be answered by stitching together various type 1 answers.
Type 3 is a question that has not been answered. It may be a bug you’ll have to find out about by reading an email chain 12 years ago or maybe a reason why epoll() doesn’t work on Linux VMs. There is no solid yes or no. You’ve most likely encountered this when reaching page 3 of your Google results and every link is purple (visited).
This is where depression and isolation hits. This is where you realize that if you can’t help yourself, no one else can (or has the experience and time to do so). This is where you must rely on your knowledge and infer an answer to your question pushing your concepts and theories to the extreme. If you solve this question, you’re solving it for someone else who may trek the same path later in the future. You’re solving it for the world!
If you’re willing to solve, attempting to solve, or even giving a reasonable inference about a type 3, you have a true engineering mindset.4 -
It fucking staggers me how many backend/devops-y people don't understand what a client side "request timeout" is, versus a server side one.
What does it mean:
The client was fed up with the servers bullshit, and decided to piss off and not wait around for the server to take forever to respond, because life's too short.
How not to solve/debug this issue:
- "I've checked the API request in tool xyz, and it works fine for me"
Congratulations, you've figured out how to call an API once, in isolation to the rest of the application, and without any excessive load. And using a different client to me, with a different configuration. Lets get back to actually looking at the issue shall we?
- "I only see HTTP 200's in the logs"
Yep, you probably will in most circumstances, because its the client complaining about it taking too long, not the server. If the server was telepathetic and knew what the client was thinking/doing at all times, we wouldn't have half of the errors we do.
- "Ah ok, I understand ... so how do I solve this?"
Your asking me? I don't fucking know, I didn't build the server! Put better logging in place and figure out why sometimes it takes forever.

Day 8 in isolation.
Im lonely..
My brother calls me.
I haven’t talked to my brother in a long time.
He believes that capitalism is the answer to everything.
It sucks to be lonely in my tiny little apartment so I actually Skyped with him today.
After a 3h call I remember why I don’t usually talk to him.
What he’s saying is:
Democracy only works if the vote of rich people is worth more.
The happiness of your people is defined by the amount of money your country has.
Thanks to Corona, the EU, Russia, Afrika and China are gonna be slums. They’ll be poor and without money.
The US is the only country that’s gonna be fine and it’s gonna be the most important country in the world.
Putin didn’t do anything illegal, he stays president because the people vote for him.
FFS, I tried to tell him my opinion on each single one of those statements, he ignored me and kept telling me how it’s the rich people that keep the clock ticking.9 -
So, now that companies are used to "WFH", maybe we can agree upon a better office for tech companies?
I do actually think the more "ideal" tech company office wouldn't have to be expensive.
It can be smaller. Any tech company worth it's salt should have discovered in the last few months that it's not just devs who can work from home. Sales, support, management — you really don't need to fight your way through highway traffic or cram yourself into a sweaty subway every day.
There's value in having an office. Not everyone can fit a good workspace in their apartment.
But we could at least center it around:
1. A bunch of small, completely soundproof isolation booths, for those who need a focus space, and can't find a silent spot at home.
2. A social lounge space, a communal living room with couches, a bar, creative relaxing stuff, whiteboards, etc. WFH can become depressing even for the most antisocial employees, chilling on a couch with some coworkers to brainstorm ideas or chat about random tech is valuable for building good relationships with your team.
The "open plan office" with rows of desks and monitors, no matter how luxuriously decorated with vertical gardens and hipster desks from reclaimed wood, can go die a fiery painful death.
I either want to work, or socialize.
Open plan offices (and it's even more dystopian suicide-inducing cousin, the cubicle) are like being unable to choose between fucking and a blowjob, so you end up humping a navel.
Oh, and conference rooms, go fuck yourself as well. I want to be able to minimize your ugly face if you plan to talk about company financial reports for 2 hours.2 -
Got a CTO at my Unity job that's younger than me, which by itself is fine, but the only reason this guy was put into that position was because the previous CTO left the company at the time where I was relatively new and he is the person most familiar with the codebase of our primary project than I was at the time.
I understood the decision at the time, but still, having a position of power being handed to them just as a matter of inheritance doesn't command my respect. Nevertheless, I withheld my judgement at the time to see how his leadership goes.
Not even 1 year in and this young CTO started making jabs at me, calling my code hard to read and incomprehensible, to my face, in front of everybody else.
Motherfucker, I don't find his code easy to read either but I went out of my way to frequently ask him, the previous CTO and other teammates to clarify what they wrote here and there. He on the other, made no attempt to ask me for clarification and instead waited until company meetings to air these grievances.
Our boss started to ask me to follow SOLID principles (even though he can't recite what that acronym means) due to complaint from the CTO guy, even though the CTO guy doesn't even follow SOLID himself! But I took the higher road and didn't flip it right back on him.
What I did propose in return though, is that the dev team start using pull requests and have a code review process if the CTO wants to sign off on everything that gets in the codebase. Sounds reasonable enough, right? Not for this guy! He immediately starts complaining that reviewing pull requests would be more work for him. Motherfucker, you refused to go to my table to ask for clarifications about my code yet still want to understand what goes on, then do code review.
It was at this point that I realized that this guy doesn't actually want me to write good, clear code. He wants me to write code HIS way so that he can understand. Yeah okay, I can accept that idea in isolation. Some open-source projects require contributors to follow certain coding convention to make the maintainers' job easier too. One project that immediately came to mind is "In-game Debug Console for Unity 3D" (disclosure: I am a contributor to this project)
But guess what?
THIS COMPANY DOESN'T HAVE A FREAKING CODING CONVENTION. NOT WRITTEN DOWN ANYWHERE. NOT EVEN A VOCAL ONE.
What this CTO guy wants from me is a complete blackbox.
To all fellow devs out there, I hope you don't work with a CTO like this, or become one.5 -
Im getting a bit tired of programming.
I have been struggling for years regarding programming. I did have some moments of perceived success, but most of the time it has been depressing.
I’m not sure if I dislike programming. But there are some aspects of it that make me feel not as passionate about it.
First of, programs are invisible. No one sees your program or you (assuming we’re talking about a non artistic dev job).
People can’t see lines of code executing, but even if they did it would be gibberish to them.
Users can only become aware of bad software and that kind of breaks my heart a bit.
You could write fast, stable, secure, easy to read, easy to update software. People won’t notice. Hell, even your boss/coworkers might not notice.
In fact, sometimes you try to do the good thing, you try to become a better dev, you try to write tests first, you try to i18n, and what do you get? “Uhh, that’s taking too much time and I don’t see the benefit”.
I know some people will say that people noticing bad service happens on every job.
But programming is the ultimate isolation job. No client has ever told me “hey that code you wrote was pretty good”. They can’t even read code.
I don’t know the users, the users don’t know me, and the users can only judge my program by the result, they can only judge the visual interface.
Let’s say you write a cool project at github. The code is great. Guess what, every language’s ecosystem out there is saturated. Everything is already written. GitHub is saturated. Your best project ends up being a just for yourself enjoyment.
I’m not saying you shouldn’t enjoy code for yourself. That’s how I bet most prolific coders start. I’ve been doing that for many years now. But at some point you want to be part of something with humans.
Imagine I’m stranded on an island with nothing no humans, just food, water and a computer. Would I write code just for myself, just for fun? I think I would off myself 3 months in.
Maybe I should do develop a more social talent...14 -
Lets create a library.
Lets use that library in a project.
Lets wrap the library call in a wrapper functione to remove duplicate code.
Lets add an overloaded wrapper call that wraps the wrapper call that calls the library to partially undo the duplicate code removal.
Lets add another overloaded wrapper call that wraps the wrapper call that wraps the wrapper call that calls the library to partially undo the duplicate code removal.
How I love it. Not.
Sometimes redundancy makes sense, especially when it are two lines which make it obvious whats going on vs a single line that leads to a fuckton of overloaded wrapper functions.
Sheeesh.
Today in "code monkeys deserve divine punishment".
Another funny thing is creating a Helper class for Junit 5 tests, making it instantiable and adding to it all kinds of shit like testcontainer creation, applications instantiation, mocks, ....
... Then " crying " why the tests are so slow.
Yeah. Logic. Isolation of concerns, each test should be a stand alone complex.
But that would lead to redundancy... Oh no.
Better to create a global state god object.
Some devs... Really amaze me, especially when they argument in ways that makes one really wonder whether they are serious or just brain dead.14 -
Having some thoughts as I sit here, trapped in the house by equal parts coronavirus and a layer of smoke drowning out the sun. The smoke is a bit of an annual thing; every year, some irresponsible jerk will go out and put their convenience and enjoyment over everyone else's quality of life.
It's a bit different this year since coronavirus has given people cabin fever. Those same people who lose their minds after weeks of isolation and suffering the indignity of wearing a mask headed out into the wilderness for recreation in record numbers.
The result is record wildfires.
Where I'm at, it's mostly coming from the eastern part of our state. The area is typified by being on the mountain range's dry side, more rural, less densely populated. Towns have burned, people lost their homes, millions of acres of land will likely burn before it's over. It happens every year; people pack up, head out into the wilderness, and cause devastation due to a simple lack of common sense or regard for the consequences of their actions.
On the west side, we see the fallout in the form of days without sunlight and abysmal air quality. We also see it in cost; we will unquestionably and without hesitation contribute to eastern recovery efforts. The western half of the state will cover almost all of the damage in both taxes and recovery aid. Our local ethos demands it.
The mountains form a kind of natural barrier, both cultural and environmental. The fact that few people cross the mountains by choice is symbolic of that divide. Those who enjoy greenery and lakes and thriving vibrant nature prefer the west, as we have them in abundance. People who have a strong appreciation for distance between themselves and other humans prefer the east, as it affords them cheaper land and few urban environments.
Here's to hoping people learn from this in 2021.17 -
This is gonna be depressing. You have been warned.
I am getting sick of people, moreso than I usually would. It's getting to the point where I'm feeling like I want complete isolation from people. Why do people get pissed at me then not tell me what I did wrong? How the fuck am I supposed to fix it?
One of my friends, S, has a lot of issues, and I've been friends with her for many years. I try to help her as much as I can because I actually care, but she rarely responds to any texts and disappears for days at a time. Then she comes back and says I worry too much and plays it off like it was nothing. Wtf?!
I give everyone hugs. If you want a hug, you'll get one from me no questions asked. I do this because I'm actually incredibly depressed and the hugs help me feel less lonely. I'm getting tired of caring so much for everyone else and having nobody actually care about me. S says that I care so much BECAUSE I don't want anyone else to feel that way, but it hurts like hell when I'm the only one who cares.
I don't care what people think about me in a sense that if they have a problem, fuck off. I do, however care that nobody seems to actually CARE. I HATE THIS SHIT. I'm getting to that point where I don't want to die, I just don't want to exist like this. Fuck everything at this point. Nobody ever responds to texts, they get pissed for no reason, just fuck it.9 -
I'm not sure where I'm going with this, but I'm fucking sick of my experience with the world.
I have a feeling that all that 1984 conspiracy type of ideas that I previously considered bullshit and fear mongering are real.
(Just to be clear, I'm not including most conspiracy theories which are very ignorant like flat earth, fake moon landing, or antivax, the people that spread those theories can die a horrible death IMHO).
Corporation consolidation is a fact and appears to become irreversible.
Because of technology, I can stay in the comfort of my house, safe from crime and be entertained without needing to have direct contact with humans.
People might say "that's your fault for not leaving the house". True but that is just how the world is.
The outside world in the cities I lived in is not a welcoming place.
Hell if you fucking find a bench it's a goddamn miracle, and if you do and sit for a long time, the police stares at you like you are up to something.
People don't talk to you because "don't talk to strangers".
It can be rare to find water or a bathroom that isn't a complete shithole.
So no wonder I rather stay at home, the outside world is hostile.
So yeah, go to a mall or something. And consume, consume, consume, because the outdoors suck.
Many pioneers thought technology was to improve the quality of life.
But no, it's just more isolation, less direct contact with people, less giving a fuck about other people.
And that's how feel about people of today. The least amount of fuck giving about others possible.
You would you would connect to more people faster, but no, the result is just millions of people browsing through the same "entertainment", shitty aggregated content.
Yes, consolidation affects internet too. Everything goes through fucking google, youtube, or whatever other fucking top 10 company.
Just like the class disparity, 1% of the things online get 99% of the exposure.
So if you're a small time anything, basically fuck you, because you're not something enormous.
Like, I wished I was a game developer, but there's thousands of brilliant indie games that get released every year, and they barely make what they're worth.
So why should I fucking try? So I can get ruined financially and I don't have a place to live in?
Software itself is so complex that is impossible to scrutinize decently.
We all laugh at congressmen asking the zuck silly questions.
Out of touch, true, but in hindsight, it is true to some extent that software is hard to regulate. Every software I on earth doesn't meet some standard one way or another.
Or maybe it's just too many of us right now.
When people scroll their search results to get access to the things they should be interested in, the only practical interface right now is being showing one link at a time.
But there's millions and millions of results.
One redeeming aspect of life is that one day I won't be alive anymore to observe the disgusting world we live in.
This could be just pure rambling and I can't prove any of the things I'm saying, I could just have been making the wrong friendships. So take this with a grain of salt.7 -
What a new years start..
"Kernel memory leaking Intel processor design flaw forces Linux, Windows redesign"
"Crucially, these updates to both Linux and Windows will incur a performance hit on Intel products. The effects are still being benchmarked, however we're looking at a ballpark figure of five to 30 per cent slow down"
"It is understood the bug is present in modern Intel processors produced in the past decade. It allows normal user programs – from database applications to JavaScript in web browsers – to discern to some extent the layout or contents of protected kernel memory areas."
"The fix is to separate the kernel's memory completely from user processes using what's called Kernel Page Table Isolation, or KPTI. At one point, Forcefully Unmap Complete Kernel With Interrupt Trampolines, aka FUCKWIT, was mulled by the Linux kernel team, giving you an idea of how annoying this has been for the developers."
>How can this security hole be abused?
"At worst, the hole could be abused by programs and logged-in users to read the contents of the kernel's memory."

Einstein supposedly has a quote attributed to him: "Perfection isn't achieved when there is nothing left to add, but when there is nothing left to remove."
I find that I aggressively refactor code where I can to only what is absolutely required. It does also have the knock on effect of reducing scope of bugs, when the code is smaller there's only so many places bugs can be.
Tesla claimed to have the ability to create designs in his head and only built things once he was satisfied that it worked in theory first, now it's rare I can do that, but I will use a repl to prototype or test modules in isolation before just hacking on the actual code.
Jobs, I mean, I know he didn't code but he was always insisting on designs that looked good and was generally uncompromising in his design centric view.

dev, ~boring
This is either a shower thought or a sober weed thought, not really sure which, but I've given some serious consideration to "team composition" and "working condition" as a facet of employment, particularly in regard to how they translate into hiring decisions and team composition.
I've put together a number of teams over the years, and in almost every case I've had to abide by an assemblage of pre-defined contexts that dictated the terms of the team working arrangement:
1. a team structure dictated to me
2. a working temporality scheme dictated to me
3. a geographic region in which I was allowed to hire
4. a headcount, position tuple I was required to abide by
I've come to regard these structures as weaknesses. It's a bit like the project management triangle in which you choose 1-2 from a list of inadequate options. Sometimes this is grounded in business reality, but more often than not it's because the people surrounding the decisions thrive on risk mitigation frameworks that become trickle down failure as they impose themselves on all aspects of the business regardless of compatibility.
At the moment, I'm in another startup that I have significantly more control over and again have found my partners discussing the imposition of structure and framework around how, where, why, who and what work people do before contact with any action. My mind is screaming at me to pull the cord, as much as I hate the expression. This stems from a single thought:
"Hierarchy and structure should arise from an understanding of a problem domain"
As engineers we develop processes based on logic; it's our job, it's what we do. Logic operates on data derived from from experiments, so in the absence of the real we perform thought experiments that attempt to reveal some fundamental fact we can use to make a determination.
In this instance we can ask ourselves the question, "what works?" The question can have a number contexts: people, effort required, time, pay, need, skills, regulation, schedule. These things in isolation all have a relative importance ( a weight ), and they can relatively expose limits of mutual exclusivity (pay > budget, skills < need, schedule < (people * time/effort)). The pre-imposed frameworks in that light are just generic attempts to abstract away those concerns based on pre-existing knowledge. There's a chance they're fine, and just generally misunderstood or misapplied; there's also a chance they're insufficient in the face of change.
Fictional entities like the "A Team," comprise a group of humans whose skills are mutually compatible, and achieve synergy by random chance. Since real life doesn't work on movie/comic book logic, it's easy to dismiss the seed of possibility there, that an organic structure can naturally evolve to function beyond its basic parts due to a natural compatibility that wasn't necessarily statistically quantifiable (par-entropic).
I'm definitely not proposing that, nor do I subscribe to the 10x ninja founders are ideal theory. Moreso, this line of reasoning leads me to the thought that team composition can be grown organically based on an acceptance of a few observed truths about shipping products:
1. demand is constant
2. skills can either be bought or developed
3. the requirement for skills grows linearly
4. hierarchy limits the potential for flexibility
5. a team's technically proficiency over time should lead to a non-linear relationship relationship between headcount and growth
Given that, I can devise a heuristic, organic framework for growing a team:
- Don't impose reporting structure before it has value (you don't have to flatten a hierarchy that doesn't exist)
- crush silos before they arise
- Identify needed skills based on objectives
- base salary projections on need, not available capital
- Hire to fill skills gap, be open to training since you have to pay for it either way
- Timelines should always account for skills gap and training efforts
- Assume churn will happen based on team dynamics
- Where someone is doesn't matter so long as it's legal. Time zones are only a problem if you make them one.
- Understand that the needs of a team are relative to a given project, so cookie cutter team composition and project management won't work in software
- Accept that failure is always a risk
- operate with the assumption that teams that are skilled, empowered and motivated are more likely to succeed.
- Culture fit is a per team thing, if the team hates each other they won't work well no matter how much time and money you throw at it
Last thing isn't derived from the train of thought, just things I feel are true:
- Training and headcount is an investment that grows linearly over time, but can have exponential value. Retain people, not services.
- "you build it, you run it" will result in happier customers, faster pivoting. Don't adopt an application maintenance strategy

Why is chromecast so stupid?
So I'm on vacation, in another country, in a hotel. I took my chromecast and downloaded offline music to be able to use the TV for at least some entertainment.
Wifi is with login, chromecast doesn't support that. And it has isolation so I was prepared that it won't work through the hotel wifi. So I used another phone to create a Hotspot, but with no internet because roaming here is crazy expensive.
I thought that would work, but chromecast simply refuses to work if there is no internet access.
Why does it need internet if I'm streaming locally anyway?
So I temporarily activate data roaming, and hooray it works, so I quickly disconnect because I have no idea what this shit of a device will start sending to Google and how much I'm gonna pay for it. It works for 10 minutes then it crashes and needs internet again.
Most useless piece of crap I ever bought.
Should have brought my RPi instead but it's busy keeping my home alive and well while I'm gone. Should have ordered in bulk.13 -
It was fun to stay home last week, this week the isolation is starting to get to me. Plus I'm PMSing. Somebody should come and hug me... 😢
Been getting really cold chills lately, so I'm not even sure if I got the damn virus.
You guys, please make a vaccine soon. I need to get out and socialize or I'll go insane. 😖7 -
Our team - if ever existed - is falling apart. Pressure raising. Release deadline probably failing. No release ready for Big Sur.
Almost seemed we were getting somewhere: More focus on code quality, unit tests, proper design, smaller classes. But somehow we now ended up in "microservice" hell; a gazillion classes, mostly tested in isolation, but together they just fail to do their job. A cheap and dirty proof of concept from March is still more capable than this pile. I really start to doubt all that "Clean code", TDD, Agility rhetorics. What does it help you, if nobody cares for the end result? It's like a month I try to hammer down that message: we have to have testable artifacts, we have to ensure code signing works, our artifact is packaged and installable, we have to give QA something they can test - but time just passes and this piece of shit software is still being killed or does nothing.
Now my knee is broken and can do no sports and are tied to my chair even more. To top it all my coffee machine broke and my internet connection was abysmal this week. Not the usual small disconnects, after which it would recover, but more annoying and enduring: often being throttled to 1.7 MB/s (ranking my connection in the slowest 7% even in Germany). My RDP sessions had compression artifacts all over the screen and a mouse click would only take effect 5 sec later.
But my Esspresso machine was just repaired. Not all hope is lost.7 -
Working with a new team and I don't understand how this is normal or ok.
Me: Does anyone need help troubleshooting the broken build or can I revert this change that broke it so I can push my change out?
Dev: Stop build shaming me, I wouldn't leave the build in a failing state.
Me: Well, I wasn't sure how long to wait, before asking.... it's been broken for 4 hours.
Dev: It's the development environment, you should expect development to be going on.
Me: Yes and appears that this project architecture doesn't support any sort of isolation for development. So nobody can deploy anything except through the development branch.
Dev: That's what development is for IMO, so it doesn't bother me.11 -
Fuck Windows 10. Period.
An amateur shit-show of junk. If you have an i3 processor it will find a way to choke it to 80% with the bloody audiodg.exe.
I have an i7 and takes 25% CPU from Windows Graph Audio Isolation to play a YouTube video and 12-13 % when idle.
Junk spaghetti with some half-useless UI over the same settings that were available in much older Windows versions.
I hate having a decent 16 GB ram, 512 SSD and Radeon and so on laptop, for it to be disabled and abused by Windows and Chrome.15 -
There was this project where a bunch a scripts had been running for three weeks analysing a bunch of fileshares. The project was in overrun and the analysis wasn't anywhere near done.
I was given complete isolation and a team of people who were instructed to do anything I needed. I had them replicate the data to as many machines as possible and I started scripting the analysis with some sample data. After half a day of collecting laptops, desktops and severs I transfered my scripts to those machines and ran the analysis in 5 hours.
I felt like I saved the project. -

What the hell has happened to Hewlett Packard?
They used to make the best notebooks around. 10-15 Years ago, basically all notebooks my family bought were from HP. These devices lasted for at least 6-8 years each.
Now I have a fucking expensive OMEN series notebook failing after 2 years with the most embarrasing hardware problems: Once a shielded piece of plastic from the bottom broke off and made a short on the mainboard, next time the way too thin power line that goes from the power plug to the PCB was placed alongside a sharp metal piece that damaged the isolation and again produced a short. When the display is moved, the webcam disconnects, which is also a hint at the production quality.
From my daughter's HP notebook the Display just broke off after like 18 months of use. When we brought it to service I asked the guy whether this happens a lot, he was like "I have 6 other notebooks of that type with the same problem in repair right now". After a repair that took forever because they couldn't get the proper replacement parts, the integrated webcam has died.
Never ever going to buy anything from this shitbrand again.4 -
I'm going nuts with this isolation, so next on my agenda... let's learn flutter!

Hopefully, you already know that the company controlled by the alledged reptiloid subhuman and olimpic testicle juggler formerly known as Mister Zuck My Tits is not to be trusted.
But as is always the case in this bitch, I've been forced into cowjizz flooded swamps' worth of stinking shit platforms for the sake of avoiding isolation.
And so, I've just found yet another way in which Facebook **THUNDERSTRIKE** ... the company, not the geriatric ward, is one of the CROWN ACHIEVEMENTS of human civilization.
Let me tell you something: some people are fucking broke. Hell, some people sleep on the streets, live on scraps, and willingly engage in acts of public defecation when provoked. But I'm not even talking about them no, just plain *broke*.
And so imagine being that guy who doesn't really use his phone much, except maybe for sharing cat pictures with mom because that's what being an absolute chad is all about. You don't get a new phone, because money is a __little__ bit tight. But THEN...
The dreaded CAPITAL strikes, and requests of you to bend and fall onto your knees so as to provide intense, intimate and manual -- as well as oral -- PLEASURE to the [NOT SO] METAPHORICAL PENIS of the """SYSTEM""".
Oh, what an abominable, drooooooling revenant that lies before you!
"Gimme your ass... " he says, menacingly, as you wail about in a futile attempt to guard and preserve the very last vestiges of your own anal virginity.
And so you fight, and kick him in the NADS with everything you have, down to the final shreds of vigor. Victory! Or so you thought...
"You must... " he mutters, mortally wounded "update WhatsApp... "
"Still you breathe?!" you exclaim, suddenly transformed into a heroic, sexy moustachoed arquebusier "After I'm done ~OILING~ my VICTORIOUS CHEST, I *shall* bestow DEATH uppon you!".
But as you rip open your shirt to apply sensual oiling to your marvellous frontal assets, your nemesis reveals it's portentous Portugal: "this new version of Android... " he gasps as he perishes "is incompatible with your device... "
"Ughh! Sacrebleu!" you shriek out in pain, realizing that you are now unable to ACCESS THE FUCKING DATA THAT IS IN YOUR OWN FUCKING HARDWARE BECAUSE OF A STUPID FORCED BINARY INCOMPATIBILITY.
That's right. Now even if I *do* get a new phone, I can't do shit about losing all of the family memes. And contacts and all of that shit, but the stickers are more important. A minor inconvenience, yes, and it didn't need all of this preamble but I was doing the dramatic fight scene bit inside my head as I was writing and I got into it.
Because the only documented way to transfer all of that data is to OPEN THE APPLICATION and scan some code, but everytime I go to do that, IT TELLS ME I NEED TO UPDATE. And every time I GO TO UPDATE, it says that MY PHONE is TOO FUCKING OLD!! AAAAAAAGHGHGHGHGHGHGHG!!!!
And you too, might be a dashing french man from centuries past, with both balls and tits down to your fucking knees, folding your arms in a position that exhumes smugness in a disgustingly irreverent and self-aggrandizing way, looking at me as a mere plebeian who cannot wrap his head around the mystical art of interacting with Google's black deuce box.
And you would be somewhat right in your judgement! But just having to fiddle about with these fucking pocket Elmo screens is such a traumatic experience for me that I'd rather lose my stickers.
[ADBREAK] Are you a debonair victorian undercover butt pirate, taking unparalleled care of your Falstaffian, highfalutin poils pubiens? Need your "sword" sharpened, as you browse through the pages of this magnanimous lexicon?

A "state of siege" and isolation can gradually erode your sense of safety and sanity.
This can come in the form of bosses who's behavior, whatever it happens to be, makes you hesitant to come into work. It can be a partner who you dont want to see after work. It can be in laws or a landlord.
In our case it's the crackhouse down the street.
These people have broken into houses, cars, stolen, vandalized, and even threatened people.
So I'm hear, chest hurting from stress, and here comes a shithead we already ran off, pipe in hand, going to smash up the truck.
Chased him off. Not even the first time.
These motherfuckers threatened the elderly lady next door. Threatened an old lady *at my work*.
God damn drug addicts every where. No god damn respect. Violent cracked out lunatics. All hours of the. night and day. Last attack was broad daylight.
And it's just been a total siege.
I'm sick of living in a nation where those who try to get by are punished, and the worst are allowed to roam around like wolves preying on people.
Its intolerable and im sick and tired of it. I have no more patience left.
Whatever your situation, meber out up with violence, shitheads, lunatics and deranged drug addicts.
Smash them in their fucking mouth if you are forced to defend you and yours. Never hesitate.19 -

Well after working a normal office job for a while I'm kinda starting to think I thrive on isolation.
All of the people, the noise, the distractions, the lights, it's all so overwhelming. I have constant anxiety attacks.
Idk does anyone relate with this? We're they ever able to overcome? Cope? Bend their employer to the will of their isolationism by working at home more often and still producing results despite the Beck and call to "please stay in the office and fit in our prescribed work time box, you robot."3 -
You had two additional weeks to improve your project.
You could research different marketing strategies to increase revenue. You could add some new features to attract more users and ensure your existing users are satisfied. Finally, you could optimize performance to make your UI quicker.
But you’ve chosen to write some unit tests. Now that two weeks are gone, you got no new features, no performance improvements and no new marketing strategies while your competitors got them all.
Tests caught obvious bugs that can even be caught by static typing, but you by definition couldn’t write tests that’ll catch unpredictable bugs, so they are still present.
After six months you realize you have to rewrite a major part of your project because your project (surprise-surprise) has to chase market needs to stay relevant. Your tests are thrown into trash along with your old code.
“Having trouble with code quality? Write a lot of tests. And I mean a *lot*. Test every file in isolation. Mock as many imports as possible.
When you're done, your code will still be bad, but now your tests will make sure it's impossible to improve anything in any meaningful way.”12 -

Headsup: if you're making a game, or want to, a good starting point is to ask a single question.
How do I want this game to feel?
A lot of people who make games get into it because they play and they say I wish this or that feature were different. Or they imagine new mechanics, or new story, or new aesthetics. These are all interesting approaches to explore.
If you're familiar with a lot of games, and why and how their designs work, starting with game
feel is great. It gives you a palette of ideas to riff on, without knowing exactly why it works, using your gut as you go. In fact a lot of designers who made great games used this approach, creating the basic form, and basically flew-blind, using the testing process to 'find the fun'.
But what if, instead of focusing on what emotions a game or mechanic evokes, we ask:
How does this system or mechanic alter the
*players behaviors*? What behaviors
*invoke* a given emotion?
And from there you can start to see the thread that connects emotion, and behavior.
In *Alien: Isolation*, the alien 'hunts' for the player, and is invulnerable. Besides its menacing look, and the dense atmosphere, its invincibility
has a powerful effect on the player. The player is prone to fear and running.
By looking at behavior first, w/ just this one game, and listing the emotions and behaviors
in pairs "Fear: Running", for example, you can start to work backwards to the systems and *conditions* that created that emotion.
In fact, by breaking designs down in this manner, it becomes easy to find parallels, and create
these emotions in games that are typically outside the given genre.
For example, if you wanted to make a game about vietnam (hold the overuse of 'fortunate son') how might we approach this?
One description might be: Play as a soldier or an insurgent during the harsh jungle warfare of vietnam. Set ambushes, scout through dense and snake infested underbrush. Identify enemy armaments to outfit your raids, and take the fight to them.
Mechanics might include
1. crawl through underbrush paths, with events to stab poisonous snacks, brush away spiders or centipedes, like the spiders in metro, hold your breathe as armed enemy units march by, etc.
2. learn to use enfilade and time your attacks.
3. run and gun chases. An ambush happens catching you off guard, you are immediately tossed behind cover, and an NPC says "we can stay and fight but we're out numbered, we should run." and the system plots out how the NPCs hem you in to direct you toward a series of
retreats and nearest cover (because its not supposed to be a battle, but a chase, so we want the player to run). Maybe it uses these NPC ambushes to occasionally push the player to interesting map objectives/locations, who knows.
4. The scouting system from State of Decay. you get a certain amount of time before you risk being 'spotted', and have to climb to the top of say, a building, or a tower, and prioritize which objects in the enemy camp to identity: trucks, anti-air, heavy guns, rockets, troop formations, carriers, comms stations, etc. And that determines what is available to 'call in' as support on the mission.
And all of this, b/c you're focusing on the player behaviors that you want, leads to the *emotions* or feelings you want the player to experience.
Point is, when you focus on the activities you want the player to *do* its a more reliable way of determining what the player will *feel*, the 'role' they'll take on, which is exactly what any good designer should want.
If we return back to Alien: Isolation, even though its a survival horror game, can we find parallels outside that genre? Well The Last of Us for one.
How so? Well TLOU is a survival third-person shooter, not a horror game, and it shows. Theres
not the omnipresent feeling of being overpowered. The player does use stealth, but mostly it's because it serves the player's main role: a hardened survivor whos a capable killer, struggling through a crapsack world. The similarity though comes in with the boss battles against the infected.
The enemy in these fights is almost unstoppable, they're a tank, and the devs have the player running from them just to survive. Many players cant help but feel a little panic as they run for their lives, especially with the superbly designed custom death scenes for joel. The point is, mechanics are more of a means to an end, and if games are paintings, and mechanics are the brushes, player behavior is the individual strokes and player emotion is the color. And by examining TLOU in this way, it becomes obvious that while its a third person survival shooter, the boss fights are *overtones* of Alien: Isolation.
And we can draw that comparison because like bach, who was deaf, and focused on the keys and not the sound, we're focused on player behavior and not strictly emotions.1 -

Cybersecurity firm Sophos announced that it has open-sourced the Sandboxie Windows sandbox-based isolation utility. According to the reports of Bleeping Computer: Sandboxie was developed by Ronen Tzur and released on June 26, 2004, as a simple utility to help run Internet Explorer within a secure and isolated sandbox environment. Later, Tzur upgraded Sandboxie to also support sandboxing any other Windows applications that required a secure virtual sandbox.
Sophos Director of Product Marketing Seth Geftic said "We are thrilled to give the code to the community. The Sandboxie tool has been built on many years highly-skilled developer work and is an example of how to integrate with Windows at a very low level. The Sandboxie user base represents some of the most passionate, forward-thinking, and knowledgeable members of the security community, and we hope this announcement will spawn a fresh wave of ideas and use cases."
You can download Sandboxie and its source code here.

think I'm starting to get why the c/c++ people are all crazy
I wanted to upgrade something so I wrote it then had to plug in the new version in 7 different crates. cool well after dozens of different file changes I found like 3 bugs and figured hey ok maybe some small edge case bug fixes and now I'm just frustrated because nothing is working and also did I mention I have like 3 deprecated crates but I haven't had a moment to rest to deprecate them fully and remove them and it's all massively annoying me
I keep just rewriting things because it's easier than changing the static typing system everywhere, but no matter what I do I just end up in more changing of the static typing system, repeat
I think I might just end at a non working codebase and lock myself up for 3 days and take some drugs and see what happens until either I pass out from lack of sleep and wake up not caring, someone finds me and takes me away, or I finally have a working product
things can't be done in chunks I guess
cuz if it works in isolation then you stress test it and it works then you plug it into the live system and heyyo look it doesn't because you didn't stress test these edge cases enough and now everything is broken and who wants to revert like 2 hours of stupid secretary work because StATiC TyPe SysTeM. so what my stress tests need to be the live system? and speaking of tests I keep have to go back to older tests and keep updating them every time the damned static type system updates so I don't want more tests
the irony in all this is suddenly for once in my life I had this funny thought of "whoa, remember when people said coding wasn't for them?". I mean if I keep shooting myself in the foot does end up feeling like a me problem. I still think like a damned computer though. literally the thing i've always been best at so I'm just laughing at the ridiculousness
(maybe it's the brain damage, let's be fair to myself)
wanted to watch a horror movie with the bf for a few days and the guy is a narcoleptic. told him I wanted to today but now look at me, I wanna lock myself in a room until I solve my disaster so how am I supposed to enjoy a movie, and do I just ditch what I'm doing and hope I give a shit later or do I blow him off? fuuuuck why2 -

First rant in a while, been up to my eyeballs in uni work; still am.
I have a week to finish my concurrent programming assignment, and I'm stressing a little.

On the other, essentially implement snapshot isolation for a sql database.
It's going to take a couple of long nights I suspect.3 -
My first exposure to computers was when i was 7 in 98. Hp Palvillion with windows 98. Got it from walmart and it cost around $1100. Brought it home and i hooked it up on my own on the living room floor. First program installed was "who wants to be a millionare", fitting that a game be the first thing installed since it was for homework. I lived 16 miles from town at the time so i really had no friends and the isolation made it hard for me to adjust in school to the point that i was a loud kid seeking attention. Then we got dialup and i found invisionfree forums which my first programing experiance with javascript started. And no I'm not talking about jquery I'm talking about the real thing.
Fast foward a year. I find an opensource arcade and learn php while writting an arcade from scratch that uses curl to mitm login to verify the user. Later that month i create a small project that dynamicly creates a signature image for the top 1000 posters on a coding forum i liked.
Then all hell broke loose when i found osdev.org, thought i was going to be a badass and make the ultimate operating system that would combine linux, windows, and mac where it could run anything. Reality Check hit me like a semi and train hitting at full force trying that and made me look into hacking. Spent alittle while breaking windows in so many ways and talking to others on irc until i was about to turn 18. Switched to ubuntu 12.04 my senior year while that was occuring. -
Data wrangling is messy
I'm doing the vegetation maps for the game today, maybe rivers if it all goes smoothly.
I could probably do it by hand, but theres something like 60-70 ecoregions to chart,
each with their own species, both fauna and flora. And each has an elevation range its
found at in real life, so I want to use the heightmap to dictate that. Who has time for that? It's a lot of manual work.
And the night prior I'm thinking "oh this will be easy."
yeah, no.
(Also why does Devrant have to mangle my line breaks? -_-)
Laid out the requirements, how I could go about it, and the more I look the more involved
it gets.
So what I think I'll do is automate it. I already automated some of the map extraction, so
I don't see why I shouldn't just go the distance.
Also it means, later on, when I have access to better, higher resolution geographic data, updating it will be a smoother process. And even though I'm only interested in flora at the moment, theres no reason I can't reuse the same system to extract fauna information.
Of course in-game design there are some things you'll want to fudge. When the players are exploring outside the rockies in a mountainous area, maybe I still want to spawn the occasional mountain lion as a mid-tier enemy, even though our survivor might be outside the cats natural habitat. This could even be the prelude to a task you have to do, go take care of a dangerous
creature outside its normal hunting range. And who knows why it is there? Wild fire? Hunted by something *more* dangerous? Poaching? Maybe a nuke plant exploded and drove all the wildlife from an adjoining region?
who knows.
Having the extraction mostly automated goes a long way to updating those lists down the road.
But for now, flora.
For deciding plants and other features of the terrain what I can do is:
* rewrite pixeltile to take file names as input,
* along with a series of colors as a key (which are put into a SET to check each pixel against)
* input each region, one at a time, as the key, and the heightmap as the source image
* output only the region in the heightmap that corresponds to the ecoregion in the key.
* write a function to extract the palette from the outputted heightmap. (is this really needed?)
* arrange colors on the bottom or side of the image by hand, along with (in text) the elevation in feet for reference.
For automating this entire process I can go one step further:
* Do this entire process with the key colors I already snagged by hand, outputting region IDs as the file names.
* setup selenium
* selenium opens a link related to each elevation-map of a specific biome, and saves the text links
(so I dont have to hand-open them)
* I'll save the species and text by hand (assuming elevation data isn't listed)
* once I have a list of species and other details, to save them to csv, or json, or another format
* I save the list of species as csv or json or another format.
* then selenium opens this list, opens wikipedia for each, one at a time, and searches the text for elevation
* selenium saves out the species name (or an "unknown") for the species, and elevation, to a text file, along with the biome ID, and maybe the elevation code (from the heightmap) as a number or a color (probably a number, simplifies changing the heightmap later on)
Having done all this, I can start to assign species types, specific world tiles. The outputs for each region act as reference.
The only problem with the existing biome map (you can see it below, its ugly) is that it has a lot of "inbetween" colors. Theres a few things I can do here. I can treat those as a "mixing" between regions, dictating the chance of one biome's plants or the other's spawning. This seems a little complicated and dependent on a scraped together standard rather than actual data. So I'm thinking instead what I'll do is I'll implement biome transitions in code, which makes more sense, and decouples it from relying on the underlaying data. also prevents species and terrain from generating in say, towns on the borders of region, where certain plants or terrain features would be unnatural. Part of what makes an ecoregion unique is that geography has lead to relative isolation and evolutionary development of each region (usually thanks to mountains, rivers, and large impassible expanses like deserts).
Maybe I'll stuff it all into a giant bson file or maybe sqlite. Don't know yet.
As an entry level programmer I may not know what I'm doing, and I may be supposed to be looking for a job, but that won't stop me from procrastinating.
Data wrangling is fun.1 -

A very long rant.. but I'm looking to share some experiences, maybe a different perspective.. huge changes at the company.
So my company is starting our microservices journey (we have a 359 retail websites at this moment)
First question was: What to build first?
The first thing we had to do was to decide what we wanted to build as our first microservice. We went looking for a microservice that can be used read only, consumers could easily implement without overhauling production software and is isolated from other processes.
We’ve ended up with building a catalog service as our first microservice. That catalog service provides consumers of the microservice information of our catalog and its most essential information about items in the catalog.
By starting with building the catalog service the team could focus on building the microservice without any time pressure. The initial functionalities of the catalog service were being created to replace existing functionality which were working fine.
Because we choose such an isolated functionality we were able to introduce the new catalog service into production step by step. Instead of replacing the search functionality of the webshops using a big-bang approach, we choose A/B split testing to measure our changes and gradually increase the load of the microservice.
Next step: Choosing a datastore
The search engine that was in production when we started this project was making user of Solr. Due to the use of Lucene it was performing very well as a search engine, but from engineering perspective it lacked some functionalities. It came short if you wanted to run it in a cluster environment, configuring it was hard and not user friendly and last but not least, development of Solr seemed to be grinded to a halt.
Elasticsearch started entering the scene as a competitor for Solr and brought interesting features. Still using Lucene, which we were happy with, it was build with clustering in mind and being provided out of the box. Managing Elasticsearch was easy since there are REST APIs for configuration and as a fallback there are YAML configurations available.
We decided to use Elasticsearch since it provides us the strengths and capabilities of Lucene with the added joy of easy configuration, clustering and a lively community driving the project.
Even bigger challenge? Which programming language will we use
The team responsible for developing this first microservice consists out of a group web developers. So when looking for a programming language for the microservice, we went searching for a language close to their hearts and expertise. At that time a typical web developer at least had knowledge of PHP and Javascript.
What we’ve noticed during researching various languages is that almost all actions done by the catalog service will boil down to the following paradigm:
- Execute a HTTP call to fetch some JSON
- Transform JSON to a desired output
- Respond with the transformed JSON
Actions that easily can be done in a parallel and asynchronous manner and mainly consists out of transforming JSON from the source to a desired output. The programming language used for the catalog service should hold strong qualifications for those kind of actions.
Another thing to notice is that some functionalities that will be built using the catalog service will result into a high level of concurrent requests. For example the type-ahead functionality will trigger several requests to the catalog service per usage of a user.
To us, PHP and .NET at that time weren’t sufficient enough to us for building the catalog service based on the requirements we’ve set. Eventually we’ve decided to use Node.js which is better suited for the things we are looking for as described earlier. Node.js provides a non-blocking I/O model and being event driven helps us developing a high performance microservice.
The leap to start programming Node.js is relatively small since it basically is Javascript. A language that is familiar for the developers around that time. While Node.js is displaying some new concepts it is relatively easy for a developer to start using it.
The beauty of microservices and the isolation it provides, is that you can choose the best tool for that particular microservice. Not all microservices will be developed using Node.js and Elasticsearch. All kinds of combinations might arise and this is what makes the microservices architecture so flexible.
Even when Node.js or Elasticsearch turns out to be a bad choice for the catalog service it is relatively easy to switch that choice for magic ‘X’ or component ‘Z’. By focussing on creating a solid API the components that are driving that API don’t matter that much. It should do what you ask of it and when it is lacking you just replace it.
Many more headaches to come later this year ;)3 -
With home isolation and remote working due to COVIV19 how do you people who live alone deal with being alone with your thoughts for 8 hours8
-
I'm not a fan. Harder to collaborate and discuss things with coworkers. I'm constantly fighting the urge to turn towards my gaming pc and start playing something. I only have one monitor instead of the 2 I have in the office. I suffer from depression and the social isolation will definitely exacerbate that. The commute to my office is less than 15 minutes so I'm barely saving any time there. Pretty much the only benefit for me is not needing headphones to listen to music.1
-
What earphones (in ear monitors) would you guys suggest? Looking for one within 50$ or ₹3000.
I work in an open office and the lack of noise isolation is killing me10 -
No one interrupting me, music ranging from rock to Mozart. And working on something to improve performance or making it better. With coffee at times. And no frigging meetings. With complete isolation.

! Dev
I don't know much about the biology, but from what i know, a virus is never treatable. In due course of time we might generate a medicine that will modify our immunity system to fight against it, like polio and when this medicine is available, all the human race would get it and that's how this epidemic ends.
Until then, we all would need a total social isolation at some instance of time, as it is being done now.
But here is my main question : what to do until then? How will the economy survive? General stores, grocery markets, restaurant and fast food, clothings and many other industries and dominantly involves direct interaction.
Shutting down and going online is also not the solution. Poor/small businesses can't afford it. companies like amazon , dominos, etc have huge network of delivery guys for e shopping, but won't that be soon banned too?
Looks like our technology in robotics and drone delivery is too slow to be proved effective in this situation . I am hoping the technology would be a solution to such situation.
What are your thoughts about it?4 -
I have always been painfully aware that us developers live in an entirely different world than the IT 'muggles'.
However now I usually browse devRant on my way to work (in the train) and listen to music. I have realised this means my time and attention is now almost exclusively devoted to the developers world. It's interesting to see how easy it is to isolate yourself from people who might behave or think differently.5 -
Anybody here use Azure VPN connections and have some time to answer questions about our implementation? I'm looking to ensure we have isolation between parts of the VPN links.4

Got flow idea : spawn 1 docker instance for each feature branch so the testing team can test each feature in isolation. Good idea or not?1

Self-isolation takes its toll on people's lives and, naturally, on interviews for our platform . So, a technical interview with a DevOps engineer at Zoom. The candidate started to surprise us already in the first minutes of the meeting. To begin with he apparently decided that the formality was enough at the first stage of the interview and decided to talk to the technical experts in a T-shirt and lying on the couch. That would have been fine, but in the middle of the interview his caring wife came in and insisted that the husband should eat his sandwiches and drink his tea. The candidate tried to remain unperturbed and undistracted, but his short "no", "don't want to", "come on!" didn't take effect. At one point, the applicant's wife escalated the tone of the conversation and threw a sandwich at him, promising to do the same with the tea. The supervisor and I became worried about the candidate and already in the voice of his wife began to persuade him to take a break for an afternoon snack. And such stressful interviews happen, and not at the company's initiative.7

whats that? where have you been phazor? gaming! i took a break off of coding! and went to play some games!
minecraft 1.17, muck, rust, farcry 5, ailen isolation, bioshock 1, 2 and infinite, even some geometry dash
after that i decided to come back and relearn html and css because if anyone who wanted to hire me i bet they would ask for a website first and see plain buttons and a depressing web page! -
I never finished it, but before I was working in the industry, I was coding through a book called Build Your Own AngularJS. My intent was to have piecemeal instruction/example in TDD and code way above the level of complexity I was used to. You essentially build the core of AngularJS in about 900 unit tests with total coverage. 1000pages long, its no walk in the park.
I gave it up when my time was short, and focused on higher level concepts: building apps, learning tools of the trade.
Now that I am getting plenty of exposure to that level, I am thinking my free learning hours may be better spent going down into the complex worlds shown in this book. A couple of things I found there really stayed with me and shaped how I think about problems. It was also very illuminating to see how complex algorithms work “in the wild”. I cant stand learning algorithms in isolation, generally speaking.
Has anyone seen this book? I know the framework itself is older now, but I don’t think that is much relevant for this learning use case.
I only know of one student who completed this. Took him a few months. He is an absolute machine. -

Is this legit ?
It is as a result of a query I have, I am curious if Docker's claims to system isolation between apps is verifiably universal.
There have been a number of attempts at virtualization that avoid VMs, and I have always wondered is there a way to access the host systems kernel through these ?
Thoughts ?18 -
Darn xml config file for a dll wouldn't load.
1) Searching Stackoverflow which says that only configs for exe files are loaded. Problem found and time to send bug report? Nah, better check source code first.
2) Downloading and reading the source for the dll. Nope, dll should explicitly load config file and read settings. Time to send problem report to author? Nah, better to test in greater isolation first.
3) Setting up isolated test. About to copy the LibName.dll.config.xml and WHAT? Note to self: You half witted twat, the file contents is XML, the bloody file extension isn't!
Now apply this sort of typo error to program code, and you will see why I use statically typed languages. -
When a child experiences extreme adversity, physical, emotional and sexual abuse, neglect and trauma; There are two possible outcomes.
1) Drug abuse, addicition, financial problems, depression, anxiety, isolation, bad grades and unemployment, early death or suicide.
Or if the child manages to survive, go past the adversity:
2) Become a superhuman. Experience entertainment, happiness in small things even more. Utilize dissociative identity disorder by achieving mental and physical prowess by false yet true belief of the persona.6
