PROBLEM: A tickets' company came to us last autumn. They said they have severe performance problems and asked us to help.
SOLUTION: covid and quarantines. All events have been ceased, noone's buying any tickets any more. Performance problems are no more. FIXED.
PROBLEM: Another company came to us recently. They said they have severe performance problems with their huge databases and asked us to help.
SOLUTION: a few days of heavy rain and their datacenter was flooded. along with the backup servers. No more data, no more performance problems with large databases. FIXED
Solving problems genie style!

For my fellow javascript devs:
var floored = 12.68 | 0;
Is much faster than:
var floored = Math.floor(12.68);
And in both cases floored === 12

WHY THE FUCK DOES MY BOSS HAVE ME MOCKING FUCKING RECAPTCHA API RESPONSES? IT'S SO FUCKING STUPID
I CAN'T MOCK THE RECAPTCHA JS METHODS SO I HAVE TO MAKE VALID-LOOKING JSON RESPONSES AND I DON'T HAVE A FUCKING CLUE HOW ANY OF IT FUCKING WORKS
THIS IS THE STUPIDEST THING ANYONE HAS EVER ASKED OF ME (okay, it isn't, but it's pretty damned close.) AND IT'S DURING MY BLOODY PERFORMANCE REVIEW.39 -
!!depression
I used to measure my performance in features per day (or week, depending on their scope), or tasks/day or loc/day for huge projects. My usual was two to three small features a day, and some progress on a larger one.
Now I’m so burned out and depressed that i measure my progress in the amount of days per week that aren’t “zeros” — as in days where i get literally nothing done. Now any day where i get _anything_ done, no matter how little, is a “good day.” I partially refactored about fifty lines of json builder spaghetti on Tuesday. That was a great day.
This week I’ve had two zeros, and it’s Thursday morning. I think it’s going to be a three zero week.
Worse: performance reviews were due weeks ago. I still haven’t written mine, and have no idea what i would even write. How can i make myself sound good when i can barely even force myself to eat or take a shower?49 -

"General bug fixes and performance improvements."3 -
While writing up this quarter's performance review, I re-read last quarter's goals, and found one my boss edited and added a minimum to: "Release more features that customers want and enjoy using, prioritized by product; minimum 4 product feature/bug tickets this quarter."
... they then proceeded to give me, not four+ product tickets, but: three security tickets (two of which are big projects), a frontend ticket that should have been assigned to the designer, and a slow query performance ticket -- on top of my existing security tickets from Q3.
How the fuck was I supposed to meet this requirement if I wasn't given any product tickets? What, finish the monster tickets in a week instead of a month or more each and beg for new product tickets from the product manager who refuses to even talk to me?
Fuck these people, seriously.8 -
I recently got mailed by our support department.
A customer using my program experienced performance issues after updating the whole system; attached is a video recorded by the customer clearly showing the difference.
I watched the video: the old version took 20 seconds to load. The new version 26. After querying the data, it's shown in a list.
The updated version showed 61 datasets instead of 6 in the old version.
I asked the supporter if he even watched the video and he answered: sure, and I'm able to see the performance issue!2 -

My first performance review as a graduate:
Boss: "we can't give you the rating you deserve because HR"
Me: "ok whatever, what can I do to get the rating I'm suppose to get?"
B: *lists job description of a senior developer* ... "Interview candidates, mentor juniors, start a project and make me profit"
Me: (if I can do that as a graduate, what am I doing here?)
My last performance review at the same company:
B: "we can't give you the rating you deserve because HR"
M: "ok what can I do to improve?"
B: *lists everything I did before the first performance review that wasn't expected of me*
M: (LoL funny, I just wanted to hear your response because I know you'd forget about the first review. Another reason to validate my resignation) -
manager: we had great feedback last week, real users were testing our app! However, we have noticed a lot of issues regards database performance and data replication...

Worked with a European consulting company to integrate some shared business data (aka. calling a service).
VP of IT called an emergency meeting (IT managers, network admins) deeply concerned about the performance of the international web site since adding our services.
VP: “The partner’s site is much slower than ours. Only common piece that could cause that is your service.”
Me: “Um, their site is vastly different than ours. I don’t think we can compare their performance to ours.”
VP: “Performance is #1! I need your service fixed ASAP!”
Me: “OK, but what exactly is slow? How did you measure their site? The servers are in Germany”
VP: “I measured performance from my house last night.”
Me: “Did you use an application?”
VP: “<laughs> oh no, I was at home. When I opened the page, I counted one Mississippi, two Mississippi, three Mississippi, then the page displayed.”
Me: “Wow…um…OK…uh…how long does our page take to load?”
VP: “Two Mississippi’s”
Me: “Um…wow…OK…wow…uh, no, we don’t measure performance like that, but I’ll work with our partners and develop a performance benchmark to determine if the shared service is behaving differently.”
VP: “Whatever it is, the service is slow. Bill, what do you think is slowing down the service?”
NetworkAdmin-Bill: “The Atlantic Ocean?”
VP got up and left the meeting.2 -
Oh dear, a scaling problem I solved was replacing some Regex matching with simpler string functions. While I'm a huge fan of Regex, it's unreal how much performance they can suck out of some high-n loops...
I got about 120x out of some critical code thus making a CPU upgrade unnecessary.8 -
When I was a young boy and I was writing my first programs, I remember I was sad because they were fast, unlike other applications I used daily and admired, with their long splash screens and the hard drive constantly making noise whenever you performed an action. At that time for me, 'slow' meant 'serious'.
It's fun to see how things have changed today: ensuring performance is a critical part of my job, and DAMMIT WHY HASN'T THE WEB PAGE LOADED YET?!?2 -

Our team was having a problem with very slow response times from a 3rd party web service they were contacting to get some device stats. No issues on the other end, but it had already been weeks. They ask me to take a look at it.
I take a few days, do a couple of benchmarks and tests and I isolate the section of code responsible. Turns out, the method they were calling would timeout if the device was offline. We ask the vendor, and they confirm this. They tell us to call methodX to check if it was up.
After having done that, lookup now only took seconds. They were annoyed that it wasn't documented but was just glad it was fixed.2 -

So today, again, I discovered the importance of unitests.
I was solving this performance issue, in which we had a few update actions for multiple entities in mongo, but it took FOREVER to complete, even when I unified it into one bulkWrite command.
Since the unified write did improve performance slightly, and we wanted to move on, we decided to let this bug go.
So there I was committing my changes when I got a rejection from the pre-commit hook since I didn't have enough unitests coverage.
Ok, let's start writing some unitests.
Some unitests also needed to test the bulk write. So there I was comparing expected with actual result, and suddenly I got a huge facepalm.
Apparently some rogue for loop iterated all entities again for each entity that needed update. So instead of getting one update per entity, I got N identical update commands per each of the N entities 🤦♂️
Needless to say, fixing this fixed the performance bug entirely.
Thank you unitests and pre-commit hooks!2 -

manager: John, you not showing up at the office today? What happened?
dev: Sir, I have to stay up all night finished the last task as required and just sleep around 6am in the morning.
manager: John, i need to tell you. your performance is very great. Our clients are happy.
You deliver all the task. We love you, John.
dev: Yes thank you so much. I am happy too, but i need to sleep now i been over time for the last 3 weeks.
Manager: don't worry john, you will get reward later.
===================================
Weeks later:
dev: i need to request for leave, i am over work and now i am sick, my eye got red and cannot look at the screen.
manager: what is happening this month, you been late to work and you not deliver the task, you are sick and this and that, and depressed and whatever... tata taata,
dev: sir, when i first started you said i could only have to work 8 hours a day, now I work more than 12 hours day. What's change?

I'm having an existential crisis with this client.
We are spending millions of $s every year to make sure the product's performance is perfect. We are testing various scenarios, fine-tuning PLABs: the environment, application, middleware, infra,... And then we provide our recommendations to the client: "To handle load of XX parallel users focusing on YY, yy and Zy APIs, use <THIS> configuration".
And what the client does?
- take our recommendations and measure the wind speed outside
- if speed is <20m/s and milk hasn't gone bad yet, add 2x more instances of API X
- otherwise add 3xX, 1xY and give more CPUs to Z
- split the setup in half and deploy in 2 completely separate load-balanced prod environments.
- <do other "tweaking">
- bomb our team with questions "why do we have slow RTs?", "why did the env crash?", "why do we have all those errors?", "why has this been overlooked in PLABs?!?"
If you're improvising despite our recommendations, wtf are we doing here???
One day I will crack. Hopefully, not sometime soon.3 -

Teaching my homeschooled son about prime numbers, which of course means we need to also teach prime number determination in Python (his coding language of choice), when leads to a discussion of processing power, and a newly rented cloud server over at digital ocean, and a search of prime number search optimizations, questioning if python is the right language, more performance optimizations, crap, the metrics I added are slowing this down, so feature flags to toggle off the metrics, crap, I actually have a real job I need to get back to. Oooh, I'm up to prime numbers in two millions, and , oh, I really should run that ssh session in screen so it keeps running if I close my laptop. I could make this a service and let it run in the background. I bet there's a library for this. He's only 9. We've already talked about encryption and the need to find large prime numbers.2

Rant!
Been working on 'MVP' features of a new product for the past 14 months. Customer has no f**king clue on how to design for performance. An uncomfortable amount of faith was placed on the ORM (ORMs are not bad as long as you know what you are doing) and the magic that the current framework provides. (Again, magic is good so long as you understand what happens behind the smoke and mirrors - but f**k all that... coz hey, productivity, right?). Customer was so focussed on features that no one ever thought of giving any attention to subtler things like 'hey, my transaction is doing a gazillion joins across trizillion tables while making a million calls to the db - maybe I should put more f**king thought into my design.' We foresaw performance and concurrency issues and raised them way ahead of the release. How did the customer respond? By hiring a performance tester. Fair enough - but what did that translate into? Nothing. Nada. Zilch. Hiring a perf tester doesn't automagically fix issues. The perf tester did not have a stable environment, a stable build or anything that is required to do a test with meaningful results. As the release date approached, the customer launched a pilot and things started failing spectacularly with the system not able to support more than 15 concurrent users. WTF! (My 'I told you so' moment) Emails started flying in all directions and the hunt for the scapegoat was on (I'm a sucker for CYA so I was covered). People started pointing in all directions but no one bothered to take a step back and understand what was causing the issues. Numero uno reason for transaction failure was deadlocks. We were using a proprietary DB with kickass tooling. No one bothered to use the tooling to understand what was the resource in contention let alone how to fix the contention. Absolute panic - its like they just froze. Debugging shit and doing the same thing again and again just so that management knew they were upto something. Most of the indexes had a fragmentation of 99.8% - I shit you not. Anywho, we now have a 'war room' where the perf tester needs to script the entire project by tonight and come up with some numbers that will amount to nothing while we stay up and keep profiling the shit out of the application under load.
Lessons learnt - When you foresee a problem make a LOT of noise to get people to act upon it and not wait till it comes back and bites you in the ass. Better yet, try not to get into a team where people can't understand the implications of shitty design choices. War room my ass!3 -

Hmmm, this feature that I added seems to make the whole process 50% longer. I need to optimize something. Let's see now...
Yeah, make that a shared resource and parallelize IO to leverage the multi-core architecture. Hash map for this, binary tree for that. This thing that gets called a million times can be written easily without a regexp. That thing can be rewritten in Rust as it's too demanding.
There! Works! And it's also a lot cleaner. Nice!
How's the performance doing? 70% longer.

I get angry every fucking time when I see such method signature:
method(int, int, int, string, string, string, string)
Sounds scary, doesn't it?
Nah. That's the reason our IDEs are so complex. So, I change this and put proper data value/struct class instead, just to make this much readable and understandable for everyone.
And, every time there is a fella that asks this utterly stupid question:
What about performance impact?
Aaaaaaaaaaaaaa fuckyutitititiigig
And. I. Have. To. Run. Performance. Tests.
Because noone understands performance and computers so I have to prove there is nothing to worry about.
I know when I will go somewhere else I will have to again prove some fuckwit that web applications are so complex already, so adding a new data structure doesn't impact its performance.12 -

I had a performance review with my boss and his boss today.
After they told me what they wanted to, they asked for my feedback. I was very honest with them and didn't only tell them the good stuff but the things I've been disappointed with as well.
Well, last year was mostly a big fat disappointment for me at the company, both on a professional and a personal level, which seemingly took them by surprise and hurt their feelings because they think it is the best place to work at. Even though I tried to make my feedback as constructive as possible, they didn't really seem to understand the problems and kept saying what a good company this is and what amazing opportunities will this year hold.
And they gave me a raise before I could even ask for it.6 -

So, first time ranting, sorry if I mess anything up.
When I first started my current job and got introduced to the system we were coding in, something seemed a little fishy to me. Didn't like the system anyway, but at least the language is a compiler language, so it runs quite quickly, right?
In theory, yeah. If the lead dev liked the IDE that came with it. But he has to REALLY fucking hate it, because rather than using it, he codes in plaintext. No syntax highlighting, no auto-indent, nothing. And he's built the entire damn system around doing that. Sadly the compiler is only integrated into the IDE, so what do we do there? Copy the code from the plaintext file to the IDE to compile it there? No no, why would you. The language has a function you can use to compile some code at runtime.
And so he does. Every. Single. Fucking. Script. There's a single main script that runs and finds the correct textfile to then runtime-compile and execute. So we effectively made a compiler language into a massively unoptimized interpreter lang.
I even mentioned that this might be a problem, but I was completely dismissed, so at that point it's not my problem anymore and I have then switched to a different system anyway.
Couple weeks later I heard the same guy complaining that the scripts were running almost the whole night so we'd probably need some better hardware or something.
Well if only there was a really obvious solution that would improve the performance by probably about a factor of 20 or so...12 -

Project Manager: I want you to work faster and make the performance faster. No excuses
Specs: potato pc9 -
2021 was really rough, saw friends going over the deep end with burnout, significant incidents to handle and a shitty manager to deal with.
It wasn't about blood and tears, it was about commuting 4 hours/day mid-pandemic to be present in the office and respond to an incident whilst having to deal with a bunch of heroes thinking they were part of a CSI: Cyber episode.
All of that just to be said that my raise "would be enough to keep me from looking elsewhere" as my manager said they were very happy with my performance.
This week I found out exactly how much this appreciation is worth: 2%. And I should consider myself lucky with this number as my performance wasn't good enough to grant me any raise whatsoever.

Guys, we need talk raw performance for a second.
Fair disclaimer - if you are for some reason intel worker, you may feel offended.
I have one fucking question.
What's the point of fucking ultra-low-power-extreme-potato CPUs like intel atoms?
Okay, okay. Power usage. Sure. So that's one.
Now tell me, why in the fucking world anyone would prefer to wait 5-10 times more for same action to happen while indeed consuming also 5-10 times less power?
Can't you just tune down "big" core and call it a day? It would be around.. a fuckton faster. I have my i7-7820HK cpu and if I dial it back to 1.2Ghz my WINDOWS with around lot of background tasks machine works fucking faster than atom-powered freaking LUBUNTU that has only firefox open.
tested i7-7820hk vs atom-x5-z8350.
opening new tab and navigating to google took on my i7 machine a under 1 second, and atom took almost 1.5 second. While having higher clock (turbo boost)
Guys, 7820hk dialled down to 1.2 ghz; 0.81v
Seriously.
I felt everything was lagging. but OS was much more responsive than atom machine...
What the fuck, Intel. It's pointless. I think I'm not only one who would gladly pay a little bit more for such difference.
i7 had clear disadvantages here, linux vs windows, clear background vs quite a few processes in background, and it had higher f***ng clock speed.
TL;DR
Intel atom processors use less power but waste a lot of time, while a little bit more power used on bigger cpu would complete task faster, thus atoms are just plain pointless garbage.
PS.
Tested in frustration at work, apparently they bought 3 craptops for presentations or some shit like that and they have mental problems becouse cheapest shit on market is more shitty than they anticipated ;-;
fucking seriously ;-;16 -

The more I work with performance, the less I like generated queries (incl. ORM-driven generators).
Like this other team came to me complaining that some query takes >3minutes to execute (an OLTP qry) and the HTTP timeout is 60 seconds, so.... there's a problem.
Sure, a simple explain analyze suggests that some UIDPK index is queried repeatedly for ~1M times (the qry plan was generated for 300k expected invocations), each Index Scan lasts for 0.15ms. So there you go.. Ofc I'd really like to see more decimal zeroes, rather than just 0.15, but still..
Rewriting the query with a CTE cut down the execution time to pathetic 0.04sec (40ms) w/o any loops in the plan.
I suggest that change to the team and I am responded a big fat NO - they cannot make any query changes since they don't have any control on their queries
....
*sigh*
....
*sigh*
but down to 0.04sec from 3+ minutes....
*sigh*
alright, let's try to VACUUM ANALYZE, although I doubt this will be of any help. IDK what I'll do if that doesn't change the execution plan :/ Prolly suggest finding a DBA (which they won't, as the client has no € for a DBA).
All this because developers, the very people sho should have COMPLETE control over the product's code, have no control over the SQLs.
This sucks!27 -
Who the hell invented this industry where smartest individuals are being evaluated by those who didn't understood technology well enough and moved to management (it's usual scenario, though there are exceptions)?
Can you imagine surgeon performance/quality being evaluated by some clerk who may or may not had studied medicine earlier, but wasn't good enough to become surgeon itself so ended up in hospital administration.
Or can you imagine bridge engineer having his/her performance/quality evaluated by someone who had built bicycle shed 5 years ago?
Damn, yet in software industry it's pretty normal.
(Don't confuse management with performance evaluation. I know management have different scope and duties, but idea that management does the performance evaluation is so damn broken.)6 -

One of the largest companies on the continent. Uses Oracle on AWS RDS with the beefiest resources available. It comes to the point where lowering the number of CPUs boosts the DB performance up (concurrency). Point is - Oracle is sweating hard during our tests. You can almost feel the smell of those hot ICs on AWS servers.
And then someone at higher levels, while sitting on a pooper, has a great idea: "I know! Let's migrate to Aurora! They say it's so much faster than anything there is!"
*migration starts*
Tests after migration: the database on the largest instance possible shits itself at 10% of the previous load: the CPU% is maxed out (sy:60%,us:40%), IO is far, far from hitting the limits.
Is it really possible Aurora will cope with the load better than Oracle? Frankly, I haven't seen any database perform better than Oracle yet. Not sure if it's worth to invest time in this adventure..2 -

Man I have no idea how my company is running as stable as they do. Every time I peak under the curtain of some piece of machinery I find such bad practices…
Just found out our in house database manager only supports listing all objects in a table, updating objects by first reading each row you need to update and only support “select *” queries.
This is after having to argue with some engineers that using http or grpc when interacting with the new service I’m writing in the none-jvm language is better than writing our own driver for their custom rpc and service discovery system.
But like honestly I’d be mad if these decisions had a visible performance impact on the business, but it somehow doesn’t… this is bizzaro world where all I learned from my 8 years experience as a professional goes out the window…1 -
Not dev, but a perf-eng confidence boost.
Our company was hired by a client to onboard perf-testing process and do some perf-related go-live stuff. Basically, make sure the app meets the SLAs.
Our company mobilized some internal resources for the task. The had 3-4 months. 2 months later they realized they won't pull it off. What a shame...
When the threat of dropping the ball and losing the client and recommendations became very real, they engaged us. Half the time, half the resources, a worried and annoyed client who now wants to control the whole initiative.
During the first 2 meetings we get the general idea of what they have, what they want. We take some time to prepare a plan to make it on time. The client argues our plan, mostly because one of the main points was mocking downstream dependencies [integrations]. He asks, then demands to do it all with live integrations. We explain why this is an incredible risk and why we should do it the proposed way. He disagrees.
Alright then... Maybe he knows smth we don't. Let's do it the risky way...
A month later test results are far from the target. I did my best with app de-bottlenecking and fine-tuning. But since the live integrations do not deliver, they hide other bottlenecks. The initiative is stuck.
Finally, the client agrees to do it with mocking. But now there's no time left as it will take almost a month to prepare mocks...
The client agrees we should have done it our way from the start. They postpone the go-live and we carry out our testing and tuning the right way.
That was one expensive and long "I told you so". But it boosted our [perf team's] confidence to the top and beyond :)
don't tell us how to do our job, unless you do want extra expenses -

Ffs, HOW!?!? Fuck! I need to get this rotten bs out.
RDS at its max capabilities from the top shelf, works OK until you scale it down and back up again. Code is the same, data is the same, load is the same, even the kitchen sink is the same, ffs, EVERYTHING is the same! Except the aws-managed db is torn down and created anew. From the SAME snapshots! But the db decides to stop performing - io tpt is shit, concurrency goes through the roof.
Re-scale it a few more times and the performance gets back to normal.
And aws folks are no better. Girish comes - says we have to optimize our queries. Rajesh comes - we are hitting the iops limit. Ankur comes - you're out of cpu. Vinod thinks it's gotta be the application to blame.
Come on guys, you are a complete waste of time for a premium fucking support!
Not to mention that 2 enhanced monitoring graphs show anythung but the read throughput.
Ffs, Amazon, even my 12yo netbook is more predictable than your enterprise paas! And that support..... BS!
We're now down to troubleshooting aws perf issues rather than our client's.... -

I'm currently at a company where we have "performance reviews" every 2 weeks, and based on the outcome we get a percentage which then is used to calculate a performance bonus.
This is simply my manager (also a developer) who has his Excel spreadsheet, looking at tasks I did over the course of the past 2 weeks and almost nitpicking to find some fault. There is no code review or software demo to see what's been done either... I was there for the first 3 months and I don't think anyone had even open my code!
And when confronted, I get told that "You should also somehow be financially liable for the goings-on in the business", along with a 2 hour meeting to support that.
This is NOT how you motivate developers!
Apologies for the long rant...

Why is it that the tech Youtubers of this world (and tech reviewers in general) tend to completely skip development as a use case, and instead (if they do ever move off gaming) focus on things like Rendering & Modelling / CAD work? I'm sure there's *way* more devs in the world than CAD guys, surely?!
And if they *do* give it the light of day, it's always a quick benchmark based on "Firefox compile time", "Linux kernel compile time" or similar. Dude, it's 2020. Much as some would like to believe otherwise, most guys stopped compiling swathes of heavy C & C++ as part of their normal workflow over a decade ago.
Real-world tests I want to know about are things like docker performance, common IDE startup performance, compile performance of different sized applications on a bunch of langs like Kotlin, C#, Java, Clojure - or node.js performance, Tensorflow performance on NVidia's vs AMDs latest GPUs, etc. I care about how many IntelliJ instances & VMs I can have open way more than how many Chrome tabs I can forget to close.

I got my new(to me) MacBook Pro last week, provided by work. I've got all my setup and config done, for the most part, and I've noticed something.
Performance is shit. Has anyone else noticed this about the 2017 and later models? The 2015 model I had before was much, much smoother. Just zooming windows, a previously butter-smooth experience, is noticeably choppy. I/O performance is garbage too. I have a small iotest script that just writes a string a couple hundred times to disk, deletes it, and repeats this activity 100,000 times. On my Linux machine at home with six year old hardware, this takes about three seconds. On my new system76 laptop it takes just over a second. On the 2017 MacBook Pro, it takes about forty seconds.
The 2017 and 2018 models are a direct downgrade in performance. Why isn't anyone talking about this?10 -

I've never been a big fan of the "Cloud hype".
Take today for example. What decent persistent storage options do I have for my EKS cluster?
- EBS -- does not support ReadWriteMany, meaning all the pods mounting that volume will have to be physically running on the same server. No HA, no HP. Bummer
- EFS -- expensive. On top of that, its performance is utter shit. Sure, I could buy more IOPS, but then again.. even more expensive.
S3 -- half-assed filesystem. Does not support O_APPEND, so basically any file modifications will have to be in a
`createFile(file+"_new", readAll(file) + new_data); removeFile(file); renameFile(file + "_new", file);`
way.
ON TOP of that, the s3 CSI has even more limitations, limiting my ability to cross-mount volumes across different applications (permission issues)
I'm running out of options. And this does not help my distrust in cloud infras...

Ever find something that's just faster than something else, but when you try to break it down and analyze it, you can't find out why?
PyPy.
I decided I'd test it with a typical discord bot-style workload (decoding a JSON theoretically from an API, checking if it contains stuff, format and then returning it). It was... 1.73x the speed of python.
(Though, granted, this code is more network dependent than anything else.)
Mean +- std dev: [kitsu-python] 62.4 us +- 2.7 us -> [kitsu-pypy] 36.1 us +- 9.2 us: 1.73x faster (-42%)
Me: Whoa, how?!
So, I proceed to write microbenches for every step. Except the JSON decoding, (1.7x faster was at least twice as slow (in one case, one hundred times slower) when tested individually.
The combination of them was faster. Huh.
By this point, I was all "sign me up!", but... asyncpg (the only sane PostgreSQL driver for python IMO, using prepared statements by default and such) has some of it's functionality written in C, for performance reasons. Not Cython, actual C that links to CPython. That means no PyPy support.
Okay then.1 -

It fucking sucks, feels like a curse. I realized I failed college because of this. Now I fear losing my job.
Right now I'm about to embark upon a great night of trying to catch up with shit I should have done earlier, which I *might* be able to focus on. I have no fun in life because I don't allow myself to, I somehow attained a relationship with someone and now that too is going to shambles because I spend so much time *trying* to do things and can't bring myself to doing them, and that time is stolen from that which I should spend with people I love and just enjoying life. I fucking hate this. I fucking hate it.
Also, I have this feature which I'm supposed to implement, and they tell me it's just an MVP which we'll use to test waters to see if people will use the functionality, it just has to work... which it does by now, but then they keep adding things before ever releasing. I feel so anxious about this and I didn't even take the job for good pay because I was desperate to leave another job which wasn't even in development. I don't want to fail this, I want to prosper as a developer. I actually wanted to do systems programming and game development, but here I am doing web shit.

Most people who talk about language performance are just repeating what they heard from others.

BACKSTORY:
I was considering creation of client-server app to learn some new language and wanted it to have the best possible performance.
The client part is not an issue, it can be whatever, really... the server choice is pain in the ass...
I have looked up web server framework benchmark here: https://techempower.com/benchmarks/
So comparing those I have 2 options:
- Actix (Rust)
- Vert.x (Java)
I was about to use Vert.x, it handles requests asynchronously which seems nice.
However I thought, what if I wanted to sell this shit someday and Java requires licenses, while Rust don't.
I am terrible if it comes to licenses, so...
QUESTION:
How does Java licensing work?
It is on client to pay it cause he is using it or on me as a product owner?
Or should I switch to Rust already?5 -

Hi, in my JS project I have to update a variable value that is getting a text input's value in order to use it dynamically with different functions across my program. What would be the best approach to doing this?
Should I make a function that updates the variable for every character typed or should I simply get the value when the function is called?
Thanks!2 -

Working all day long on a new feature to resolve a perf issue but realised at 6pm only that everything was pointless. I love my job

The feeling when you choke your code with cython so much that you manage to get under a single second from almost 2s per quite a lot of calculations with already optimized code.
Another X-mas came! -
I currently have a Surface Pro 3 and am wanting to upgrade. I'm a software dev student at my college and I'm noticing the performance is just slowly getting worse and worse. I recently reset it to start fresh, still slows down in overall performance and battery life.
Any good recommendations? If possible I would like to avoid the Pro due to the kickstand gimmick.7
