Frontend & backend dev conversation
Backend Dev: what will you be working on?
Frontend dev: i will be creating a nice animated loader. You?
Backend Dev: i will be working on optimizing the backend so that no one can see your loader.

Client: Can you provide some kind of guaranteed timeline that you're going to be able to move our website to our new servers with the optimizations implemented? I know you said it should take a week, but we have 3 weeks to get this moved over and we cannot afford to be double billed. I'm waiting to fire up the new server until you can confirm.
Me: As I said, it SHOULD take about a week, but that's factoring in ONLY the modifications being made for optimization and a QA call to review the website. This does not account for your hosting provider needing to spin up a new server.
We also never offered to move your website over to said new server. I sent detailed instructions for your provider to move a copy of the entire website over and have it configured and ready to point your domain over to, in order to save time and money since your provider won't give us the access necessary to perform a server-to-server transfer. If you are implying that I need to move the website over myself, you will be billed for that migration, however long it takes.
Client: So you're telling me that we paid $950 for 10 hours of work and that DOESN'T include making the changes live?
Me: Why would you think that the 10 hours that we're logged for the process of optimizing your website include additional time that has not been measured? When you build out a custom product for a customer, do you eat the shipping charges to deliver it? That is a rhetorical question of course, because I know you charge for shipping as well. My point is that we charge for delivery just as you do, because it requires our time and manpower.
All of this could have been avoided, but you are the one that enforced the strict requirement that we cannot take the website down for even 1 hour during off-peak times to incorporate the changes we made on our testbed, so we're having to go through this circus in order to deliver the work we performed.
I'm not going to give you a guarantee of any kind because there are too many factors that are not within our control, and we're not going to trap ourselves so you have a scapegoat to throw under the bus if your boss looks to you for accountability. I will reiterate that we estimate it would take about a week to implement, test and run through a full QA together, as we have other clients within our queue and our time must be appropriately blocked out each day. However, the longer you take to pull the trigger on this new server, the longer it will take on my end to get the work scheduled within the queue.
Client: If we get double billed, we're taking that out of what we have remaining to pay you.
Me: On the subject of paying us, you signed a contract acknowledging that you would pay us the remaining 50% after you approved the changes, which you did last week, in order for us to deliver the project. Thank you for the reminder that your remaining balance has not yet been paid. I'll have our CFO resend the invoice for you to remit payment before we proceed any further.

I love it when clients give me shit. I just give it right back.6 -
Biggest scaling challenge?
The imaginary scaling issues from clients.
Client : How do you cope with data that's a billion times bigger than our current data set? Can you handle that? How much longer will it take to access some data then?
I could then give a speech about optimizing internal data structures and access algorithms that work with O(log n) complexity, but that wouldn't help, non-tech people will not understand that.
And telling someone, the system will be outdated and hopefully been replaced when that amount of data is reached, would be misinterpreted as "Our system can not handle it".
So the usual answer is: "No problem, our algorithms are optimized so they can handle any amount of data"6 -
Just finished assisting a junior dev with optimizing his code.
What used to take 2+ hours now takes less than 4 mins! 😎7 -
Had to wirte and optimize a C++ program that finds for 1000x1000x1000 grid points the 100 nearest points for each (with an additional factor to make it more complicated).
It had to run in under 18 minutes to pass. No matter what I did I couldn't get it fast enough. I tried kd-trees, caching of certain points, optimizing distamce calculations by ommiting any irrelevant factor, saving points' calculated squares etc etc. When Ibwas down to 20 minutes, I realized, that my makefile had an error and ignored the - O3 flag...
Well, it actually ran 5 minutes with -O3.8 -
> Root struggles with her ticket
> Boss struggles too
> Also: random thoughts about this job
I've been sick lately, and it's the kind of sick where I'm exhausted all day, every day (infuriatingly, except at night). While tired, I can't think, so I can't really work, but I'm during my probationary period at work, so I've still been doing my best -- which, honestly, is pretty shit right now.
My current project involves legal agreements, and changing agent authorization methods (written, telephone recording, or letting the user click a link). Each of these, and depending on the type of transaction, requires a different legal agreement. And the logic and structure surrounding these is intricate and confusing to follow. I've been struggling through this and the project's ever-expanding scope for weeks, and specifically the agreements logic for the past few days. I've felt embarrassed and guilty for making so little progress, and that (and a bunch of other things) are making me depressed.
Today, I finally gave up and asked my boss for help. We had an hour and a half call where we worked through it together (at 6pm...). Despite having written quite a bit of the code and tests, he was often saying things like "How is this not working? This doesn't make any sense." So I don't feel quite so bad now.
I knew the code was complex and sprawling and unintuitive, but seeing one of its authors struggling too was really cathartic.
On an unrelated note, I asked the most senior dev (a Macintosh Lisa dev) why everything was using strings instead of symbols (in Rails) since symbols are much faster. That got him looking into the benchmarks, and he found that symbols are about twice as fast (for his minimal test, anyway), and he suggested we switch to those. His word is gold; mine is ignorable. kind of annoying. but anyway, he further went into optimizing the lookup of a giant array of strings, and discovered bsearch. (it's a divide-and-conquer lookup). and here I am wondering why they didn't implement it that way to begin with. 🙄
I don't think I'm learning much here, except how to work with a "mature" codebase. To take a page from @Rutee07, I think "mature" here means the same as in porn: not something you ever want ot see or think about.
I mean, I'm learning other things, too, like how to delegate methods from one model to another, but I have yet to see why you would want to. Every use of it I've explored thus far has just complicated things, like delegating methods on a child of a 1:n relation to the parent. Which child? How does that work? No bloody clue! but it does, somehow, after I copy/pasted a bunch of esoteric legacy bs and fussed with it enough.
I feel like once I get a good grasp of the various payment wrappers, verification/anti-fraud integration, and per-business fraud rules I'll have learned most of what they can offer. Specifically those because I had written a baby version of them at a previous job (Hell), and was trying to architect exactly what this company already has built.
I like a few things about this company. I like my boss. I like the remote work. I like the code reviews. I like the pay. I like the office and some socializing twice a year.
But I don't like the codebase. at all. and I don't have any friends here. My boss is friendly, but he's not a friend. I feel like my last boss (both bosses) were, or could have been if I was more social. But here? I feel alone. I'm assigned work, and my boss is friendly when talking about work, but that's all he's there for. Out of the two female devs I work with, one basically just ignores me, and the other only ever talks about work in ways I can barely understand, and she's a little pushy, and just... really irritating. The "senior" devs (in quotes because they're honestly not amazing) just don't have time, which i understand. but at the same time... i don't have *anyone* to talk to. It really sucks.
I'm not happy here.
I miss my last job.
But the reason I left that one is because this job allows me to move and work remotely. I got a counter-offer from them exactly matching my current job, sans the code reviews. but we haven't moved yet. and if I leave and go back there without having moved, it'll look like i just abandoned them. and that's the last thing I want them to think.
So, I'm stuck here for awhile.
not that it's a bad thing, but i'm feeling overwhelmed and stressed. and it's just not a good fit. but maybe I'll actually start learning things. and I suppose that's also why I took the job.
So, ever onward, I guess.
It would just be nice if I could take some of the happy along with me.7 -
Yeah Mozilla fuck merit and fuck you too!
This, this is what I was talking about when the fucking CoC came out and everyone (including it's author) started it using it as a political weapon.
You castrated fucking virgins! Mozilla, I want to support you I really don't like chrome but you always manage to disappoint everyone. I'm tired, tired of you morally superior socialists infecting my fucking workplace, entertainment and news.
This is just an excuse for lazy assholes to have their cake and eat it too and it's damn fucking INSULTING to us "minorities", I can work to get nice things just like anyone else bitch! having another skin color is not a disability!
Worst of all, you seem to have straight out millennial retards making these decisions seeing as it's based on an article from a washed up "gender research" professor that thinks Barbie Doctor is problematic, the most biased and dumb source you can possibly pull out of your ass.
Two classmates were murdered this morning, do you really think we care about what your diversity and inclusion Dept thinks it's problematic? You delusional halfwits, the only comforting thought is that your soft bigotry will perish alongside your product when it inevitably diminishes it's quality for sake of "equality".
Want to make better products? Ditch your useless diversity and inclusion department and start optimizing the memory consumption on firefox.
Want to help minorities? Start paying your outsourced developers decently.
I hope this helps people who thought including politics in software development wouldn't have dire consecuences to open their eyes; if not, oh well I guess people will get it when mozilla keeps going down the drain and they get fired because they just outsourced their work in the name of "diversity" just to save money.

Have I have fallen in love with Python because she is beautiful?
Answer
Vaibhav Mallya, Proud Parseltongue. Passionate about the language, fairly experienced (since ...
Written Nov 23, 2010 · Upvoted by Timothy Johnson, PhD student, Computer Science
There's nothing wrong with falling in love with a programming language for her looks. I mean, let's face it - Python does have a rockin' body of modules, and a damn good set of utilities and interpreters on various platforms. Her whitespace-sensitive syntax is easy on the eyes, and it's a beautiful sight to wake up to in the morning after a long night of debugging. The way she sways those releases on a consistent cycle - she knows how to treat you right, you know?
But let's face it - a lot of other languages see the attention she's getting, and they get jealous. Really jealous. They try and make her feel bad by pointing out the GIL, and they try and convince her that she's not "good enough" for parallel programming or enterprise-level applications. They say that her lack of static typing gives her programmers headaches, and that as an interpreted language, she's not fast enough for performance-critical applications.
She hears what those other, older languages like Java and C++ say, and she thinks she's not stable or mature enough. She hears what those shallow, beauty-obsessed languages like Ruby say, and she thinks she's not pretty enough. But she's trying really hard, you know? She hits the gym every day, trying to come up with new and better ways of JIT'ing and optimizing. She's experimenting with new platforms and compilation techniques all the time. She wants you to love her more, because she cares.
But then you hear about how bad she feels, and how hard she's trying, and you just look into her eyes, sighing. You take Python out for a walk - holding her hand - and tell her that she's the most beautiful language in the world, but that's not the only reason you love her.
You tell her she was raised right - Guido gave her core functionality and a deep philosophy she's never forgotten. You tell her you appreciate her consistent releases and her detailed and descriptive documentation. You tell her that she has a great set of friends who are supportive and understanding - friends like Google, Quora, and Facebook. And finally, with tears in your eyes, you tell her that with her broad community support, ease of development, and well-supported frameworks, you know she's a language you want to be with for a long, long time.
After saying all this, you look around and notice that the two of you are alone. Letting go of Python's hand, you start to get down on one knee. Her eyes get wide as you try and say the words - but she just puts her finger on your lips and whispers, "Yes".
The moon is bright. You know things are going to be okay now.

I apparently got home drunk last night and watched half an hour of a talk on optimizing compression for web applications.
Now I'm caressing a slight hangover with coffee and watching the rest of it.1 -
Junior coder says validation is not needed on asp.net mvc form pages because it is not in the requirements or part of the definition of done. Wants to argue about it. Refuses to do it. Says I am over optimizing or some shit like that. Good luck with that. If you can't figure that one out or listen to feedback perhaps you should become a project manager not a programmer.11

This is going to be a rant, but personally, I'm pleased with the outcome of my life now.
I was part of a community for a few years and decided to help them out with my knowledge of programming Lua nearly 2 years ago since they lacked developers for the project itself.
Since it was sort of a custom language that they modified how Lua worked on it, it took me a bit to adapt, but within a few weeks, I was pretty fluent in this so-called custom language they had. Began working on some major updates, additions, removals, and just optimizing this code base. It was a pretty old code base and needed a good chunk of love.
A few months later, I've implemented loads of features, optimized the base whenever I could, and then things start taking a turn for the worse. We get new 'developers' who haven't ever coded the language, and worse they couldn't afford to provide them development servers thus they ended up breaking my servers. I helped them and they learned, they were decent, but now the Seniors and CEO's of the project began to take a toll on me.
I was told that this community had a reputation of driving out developers, ruining their reputations, and that is what started happening. I started getting questioned if I was loyal to helping them, that I've become lazy, even though they were explained I've had mental health issues for a few years and have been hospitalized multiple times.
These sort of attacks kept happening for months, and then they finally pushed my buttons, where I was talking to another Senior of how we should redo the base since it's just so massive and a few tiny updates to the base take a few days to implement across the entire code. What instead happened was that I went to sleep, and this Senior told the CEO I was going to steal the code base and go sell it...
I woke up to messages of how the CEO is all pissed off, and that this what the Senior said. At this point, I started responding with, fuck it. I was so sick and fucking tired of their bullshit. I was the only fucking competent developer, and I did more work in the few months I was there then some people did in 2 or 3 years.
A few hours later I decided to go chat with the CEO and explained what was truly brought up, and he just brushed it off like I was lying. At that point, I lost it. I told him why the code base was horrible since he hired stupid ass developers. He didn't know how to code. People wanted certain items, and he wouldn't be able to add them for fucking months and players sit there making fun of it. Some people state the only differences they see within the code is the code I've done. Basically, he was an incompetent fuck that said he knew what he was doing, and had all these big plans for the future yet couldn't listen to the only competent developer and fucking claimed bullshit.
Now a few months have gone by, I'm looking at their community and it's basically dead with no proper updates except for copy and paste updates claiming to be custom coded. While I'm working on my real life businesses (Which are currently being a headache, but within the year should resolve its issues), starting University for my Computer Science degree here soon, and even considering building my own game here.
Basically, karma is a bitch and that's why when you get loyal people in your life, keep them. (Writing this at 3 am after a few drinks, hopefully, it made sense, I think it does.)
Anyways, goodnight everyone.5 -
I just launched a small web service/app. I know this looks like a promo thing, but it's completely non-profit, open source and I'm only in it for the experience. So...
Introducing: https://gol.li
All this little app offers is a personal micro site that lists all your social network profiles. Basically share one link for all your different profiles. And yes, it includes DevRant of course. :)
There's also an iframe template for easy integration into other web apps and for the devs there's a super simple REST GET endpoint for inclusion of the data in your own apps.
The whole thing is on GitHub and I'd be more than happy for any kind of contribution. I'm looking forward to adding features like more personalization, optimizing stuff and fixing things. Also any suggestions on services you'd like see. Pretty much anything that involves a public profile goes.
I know this isn't exactly world changing, but it's just a thing I wanted to do for some time now, getting my own little app out there.9 -
Biggest challenge I overcame as dev? One of many.
Avoiding a life sentence when the 'powers that be' targeted one of my libraries for the root cause of system performance issues and I didn't correct that accusation with a flame thrower.
What the accusation? What I named the library. Yep. The *name* was causing every single problem in the system.
Panorama (very, very expensive APM system at the time) identified my library in it's analysis, the calls to/from SQLServer was the bottleneck
We had one of Panorama's engineers on-site and he asked what (not the actual name) MyLibrary was and (I'll preface I did not know or involved in any of the so-called 'research') a crack team of developers+managers researched the system thoroughly and found MyLibrary was used in just about every project. I wrote the .Net 1.1 MyLibrary as a mini-ORM to simplify the execution of database code (stored procs, etc) and gracefully handle+log database exceptions (auto-logged details such as the target db, stored procedure name, parameter values, etc, everything you'd need to troubleshoot database errors). This was before Dapper and the other fancy tools used by kids these days.
By the time the news got to me, there was a team cobbled together who's only focus was to remove any/every trace of MyLibrary from the code base. Using Waterfall, they calculated it would take at least a year to remove+replace MyLibrary with the equivalent ADO.Net plumbing.
In a department wide meeting:
DeptMgr: "This day forward, no one is to use MyLibrary to access the database! It's slow, unprofessionally named, and the root cause of all the database issues."
Me: "What about MyLibrary is slow? It's excecuting standard the ADO.Net code. Only extra bit of code is the exception handling to capture the details when the exception is logged."
DeptMgr: "We've spent the last 6 weeks with the Panorama engineer and he's identified MyLibrary as the cause. Company has spent over $100,000 on this software and we have to make fact based decisions. Look at this slide ... "
<DeptMgr shows a histogram of the stacktrace, showing MyLibrary as the slowest>
Me: "You do realize that the execution time is the database call itself, not the code. In that example, the invoice call, it's the stored procedure that taking 5 seconds, not MyLibrary."
<at this point, DeptMgr is getting red-face mad>
AreaMgr: "Yes...yes...but if we stopped using MyLibrary, removing the unnecessary layers, will make the code run faster."
<typical headknodd-ers knod their heads in agreement>
Dev01: "The loading of MyLibrary takes CPU cycles away from code that supports our customers. Every CPU cycle counts."
<headknod-ding continues>
Me: "I'm really confused. Maybe I'm looking at the data wrong. On the slide where you highlighted all the bottlenecks, the histogram shows the latency is the database, I mean...it's right there, in red. Am I looking at it wrong?"
<this was meeting with 20+ other devs, mgrs, a VP, the Panorama engineer>
DeptMgr: "Yes you are! I know MyLibrary is your baby. You need to check your ego at the door and face the facts. Your MyLibrary is a failed experiment and needs to be exterminated from this system!"
Fast forward 9 months, maybe 50% of the projects updated, come across the documentation left from the Panorama. Even after the removal of MyLibrary, there was zero increases in performance. The engineer recommended DBAs start optimizing their indexes and other N+1 problems discovered. I decide to ask the developer who lead the re-write.
Me: "I see that removing MyLibrary did nothing to improve performance."
Dev: "Yes, DeptMgr was pissed. He was ready to throw the Panorama engineer out a window when he said the problems were in the database all along. Didn't you say that?"
Me: "Um, so is this re-write project dead?"
Dev: "No. Removing MyLibrary introduced all kinds of bugs. All the boilerplate ADO.Net code caused a lot of unhandled exceptions, then we had to go back and write exception handling code."
Me: "What a failure. What dipshit would think writing more code leads to less bugs?"
Dev: "I know, I know. We're so far behind schedule. We had to come up with something. I ended up writing a library to make replacing MyLibrary easier. I called it KnightRider. Like the TV show. Everyone is excited to speed up their code with KnightRider. Same method names, same exception handling. All we have to do is replace MyLibrary with KnightRider and we're done."
Me: "Won't the bottlenecks then point to KnightRider?"
Dev: "Meh, not my problem. Panorama meets primarily with the DBAs and the networking team now. I doubt we ever use Panorama to look at our C# code."
Needless to say, I was (still) pissed that they had used MyLibrary as dirty word and a scapegoat for months when they *knew* where the problems were. Pissed enough for a flamethrower? Maybe.6 -
Today I come across something interresting in SQL Server.
I was optimizing a report query and in the SSMS windows runned in 10 seconds for 3000 rows.
Put it to a stored procedure took me 5 minutes for getting 100 rows.
I was like WTF?
After some research I found out that the problem was that I was using the Stored Procedure parameters in the query.
Created local variables for the parameters and poof... 10 seconds again.
So if you are creating Stored Procedures in SQL Server DO NOT USE THE PARAMETERS FROM THE PROCEDURE. CREATE LOCAL VARIABLES.5 -
This is so true!
Too many companies in the past years have been focusing on moving rendering to the client, and not optimizing their webpages that we lost sight of making efficient and fast websites.6 -
Once upon a time, one or two jobs ago, a really awesome engineer specced out a distributed search application in response to a business need. This company was managed pretty oldschool and required a ton of paperwork and approvals.
The engineer spent many weeks running tests and optimizing the hell out of this app cluster. It flew, and he had the data to prove it could handle production workloads (think hundreds of terabytes of data being processed every single day)
Part of the way he achieved this was having RAID0 on all of the servers to maximize I/O throughput. He didn't care much about data loss, since the application itself was fault tolerant on a much more granular level.
Management, hearing about this, absolutely flipped their shit and demanded RAID6 instead. This despite the conclusive data that the engineer had that proved RAID6 couldn't keep up.
He more or less got told to STFU.
Even this despite the fact that a RAID restripe would actually take many times longer than rebuilding the failed node from scratch (a process that took about 30 minutes by hand, and could probably be automated to be done in less than five), causing a longer exposure to actual data loss throughout the length of the days-long array rebuild time.
The ill-thought-out requirement added about 50% to the cost of the project (*many* more hard drives now required), beyond the original budget, and the subsequent bureaucratic wrangling resulted in a late product launch.
6 months or so later, after real customers were using this product, the app was buckling under around half of its expected workload. A friend of the engineer suggested to management to try RAID0. Sure enough, that resolved the I/O bottleneck.
This rage-inducing story has a happy ending, though! Said engineer left the company not long after this incident, citing it as a reason for his departure. He was immediately hired by another company, making integer multiples of his prior salary.
The product the company botched the launch of by ignoring his spec? It died a few months later. Maybe the poor customer experience was to blame? Maybe the late launch? Maybe it was another reason entirely.
Either way, millions of dollars of hardware now sat fallow. This was a black eye on the company all the way up to the C-level.
tl;dr: Listen to your engineers. You hired them for their expertise.5 -

For the first time I am feeling like.... I hate my job.
Agile and Scrum can be fucked, but at least there is a work methodology. I was hired by a company being run the old school way.
These guys never heard of git??
- Fuck you. We never used git and neither should you.
Client company does not want to give me push/pull access to their gitlab instance??
- Fuck you, you can use our RDP server for that.
Project planning features be damned, they've got email, Teams and videocalls!
Can I develop in peace? Fuck no, I have to give IT support to the guy who hired me.
Our timeline is defined IN A FUCKING WORD DOCUMENT FOR FUCKS SAKE. I can't connect Issues to milestones in a Word doc
Oh, and the customer is running everything on prem. If there is a need to scale up, FUCK ME. I should have specified 20 machines from the get go or gtfo. We're using 2 machines to run 8 different services that are going to be ingesting and computing data.
They want state of the art on a cheapskate.
And I have nothing else lined up at the moment. Although I am soon to renew the contract... This contract binds me with professional responsibility for a project being ran by people who do not give a single fuck about optimizing the work process.3 -
Making python 2x faster by replacing enums with literal values.
Pros, it's faster, cons, it's unreadable.
God I miss compiled languages. At least optimizing them requires intelligent problem solving.
It's a text parser state machine transition so it's a code hot spot, so this kind of optimization is worthwhile. But it's kinda annoying.
Next is get rid of any semblance of readability and replace the match with an array index...31 -
Consumers ruined software development and we the developers have little to no chance of changing it.
Recently I read a great blog post by someone called Nikita, the blog post talks mostly about the lack of efficiency and waste of resources modern software has and even tho I agree with the sentiment I don't agree with some things.
First of all the way the author compares software engineering to mechanical, civil and aeroespacial engineering is flawed, why? Because they all directly impact the average consumer more than laggy chrome.
Do you know why car engines have reached such high efficiency numbers? Gas prices keep increasing, why is building a skyscraper better, cheaper and safer than before? Consumers want cheaper and safer buildings, why are airplanes so carefully engineered? Consumers want safer and cheaper flights.
Wanna know what the average software consumer wants? Shiny "beautiful" software that is either dirt ship or free and does what it needs to. The difference between our end product is that average consumers DON'T see the end product, they just experience the light, intuitive experience we are demanded to provide! It's not for nothing that the stereotype of "wizard" still exists, for the average folk magic and electricity makes their devices function and we are to blame, we did our jobs TOO well!
Don't get me wrong, I am about to become a software engineer and efficient, elegant, quality code is the second best eye candy next to a 21yo LA model. BUT dirt cheap software doesn't mean quality software, software developed in a hurry is not quality software and that's what douchebag bosses and consumers demand! They want it cheap, they want it shiny and they wanted it yesterday!
Just look at where the actual effort is going, devs focus on delivering half baked solutions on time just to "harden" the software later and I don't blame them, complete, quality, efficient solutions take time and effort and that costs money, money companies and users don't want to invest most of the time. Who gets to worry about efficiency and ms speed gains? Big ass companies where every second counts because it directly affects their bottom line.
People don't give a shit and it sucks but they forfeit the right to complain the moment they start screaming about the buttons not glaring when hovered upon rather than the 60sec bootup, actual efforts to make quality software are made on people's own time or time critical projects.
You put up a nice example with the python tweet snippet, you have a python script that runs everyday and takes 1.6 seconds, what if I told you I'll pay you 50 cents for you to translate it to Rust and it takes you 6 hours or better what if you do it for free?
The answer to that sort of questions is given every day when "enganeers" across the lake claim to make you an Uber app for 100 bucks in 5 days, people just don't care, we do and that's why developers often end up with the fancy stuff and creating startups from the ground up, they put in the effort and they are compensated for it.
I agree things will get better, things are getting better and we are working to make programs and systems more efficient (specially in the Open Source community or high end Tech companies) but unless consumers and university teachers change their mindset not much can be done about the regular folk.
For now my mother doesn't care if her Android phone takes too much time to turn on as long as it runs Candy Crush just fine. On my part I'll keep programming the best I can, optimizing the best I can for my own projects and others because that's just how I roll, but if I'm hungry I won't hesitate to give you the performance you pay for.

I had spent the last year working on a online store power by woocommerce with over 100k products from various suppliers. This online store utilized a custom API that would take the various formats that suppliers offer their inventory in and made them consistent. Now everything was going swimmingly initially, but then I began adding more and more products using a plug-in called WP all import. I reached around 100k products and the site would take up to an entire minute to load sometimes timing out. I got desperate so I installed several caching plugins, but to no avail this did not help me. The site was originally only supposed to take three to four months but ended up taking an entire year. Then, just yesterday I found out what went wrong and why this woocommerce website with all of these optimizations was still taking anywhere from 60 to 90 seconds to load, or just timing out entirely. I had initially thought that I needed a beefier server so I moved it to a high CPU digitalocean VM. While this did help a little bit, the site was still very slow and now I had very high CPU usage RAM usage and high disk IO. I was seriously stumped the Apache process was using a high amount of CPU and IO along with MYSQL as well. It wasn't until I started digging deeper into the database that I actually found out what the issue was. As I was loading the site I would run 'show process list' in the SQL terminal, I began to notice a very significant load time for one of the tables, so I went to go and check it out. What I did was I ran a select all query on that particular table just to see how full it was and SQL returned a error saying that I had exceeded the maximum packet size. So I was like okay what the fuck...
So I exited my SQL and re-entered it this time with a higher packet size. I ran a query that would count how many rows were in this particular table and the number came out to being in the millions. I was surprised, and what's worse is that this table belong to a plugin that I had attempted to use early in the development process to cache the site. The plugin was deactivated but apparently it had left PHP files within the wp content directory outside of the actual plugin directory, so it's still executing scripts even though the plugin itself was disabled. Basically every time I would change anything on the site, it would recache the whole thing, and it didn't delete any old records. So 100k+ products caching on saves with no garbage collection... You do the math, it's gonna be a heavy ass database. Not only that but it was serialized data, so when it did pull this metric shit ton of spaghetti from the database, PHP then had to deserialize it. Hence the high ass CPU load. I had caching enabled on the MySQL end of things so that ate the ram. I was really desperate to get this thing running.
Honest to God the main reason why this website took so long was because the load times made it miserable to work on. I just thought that the hardware that I had the site on was inadequate. I had initially started the development on a small Linux VM which apparently wasn't enough, which is why I moved it to digitalocean which also seemed to not be enough, so from there I moved to a dedicated server which still didn't seem to be enough. I was probably a few more 60-second wait times or timeouts from recommending a server cluster to my client who I know would not be willing to purchase it. The client who I promised this site to have completed in 3 months and has waited a year. Seriously, I would tell people the struggles that I would go through with this particular site and they would just tell me to just drop the site; just take the money, just take the loss. I refused to, this was really the only thing that was kicking my ass. I present myself as this high-and-mighty developer like I'm just really good at what I do but then I have this WordPress site that's just beating the shit out of me for a year. It was a very big learning experience and it was also very humbling as well, it made me realize that I really don't know as much as I think I might. It was evidence that there is still so much more to learn out there, I did learn a lot from that experience especially about optimizing websites the different types of methods to do that particular lonely on the server side and I'll be able to utilize this knowledge in the future.
I guess the moral of the story is, never really give up. Ultimately things might get so bad that you're running on hopes and dreams. Those experiences are generally the most humbling. Now I can finally present the site that I am basically a year late on to the client who will be so happy that I did not give up on the project entirely. I'll have experienced this feeling of pure euphoria, and help the small business significantly grow their revenue. Helping others is very fulfilling for me, even at my own expense.
Anyways, gonna stop ranting. Running out of characters. If you're still here... Ty for reading :')7 -
Second coolest project that I have worked was optimizing an algorithm that used images to speedup by 2000x by parallel processing. While the cpu took 7.34 seconds to process just one image and source, the parallel embedded code did it just in 0.0034 :) The coolest one is still in progress where I am building an Ai for my mac control ;)

take adderall and stay up coding all night extremely effectively, but then u keep going and by the end of it you're just optimizing your vim plugins and installing a new linter

Worked on optimizing the Firefox add-on I'm writing yesterday evening, was about to go to bed and packaged/installed it onto my normal Firefox (not Firefox for developers).
It worked perfectly fine on the developer version: hardly anything happens on the normal Firefox version and I took all debugging console.log's out 😬
Fuck me. Going to try to fix this shit tonight but damn.1 -
I manage one of the shittiest parts of the codebase in the company. I spent the last couple of months rewriting and refactoring and optimizing without being asked so i can make my life easier and earn some good employee points.
Last Tuesday I got a call from the CTO, he was like "i love what you did but i think changing the language used for that would be cool so i rewrote some of it in Node, lets finish it up together and use the version of it in node from now on."2 -
Finally after a couple of years, we finally finished our game for... Windows phone. When we started the only real choice was to develop in silverlight.
Now silverlight has been discontinued and microsoft released uwp, no real help to convert to uwp (I know mobilize bridge exists, but it is not very good) since many features does not exist yet in uwp :/
But hey that's expected right? But couldn't microsoft at least ensure performance of silverlight apps on win10 mobile??? We have used a lot of time optimizing that the game runs smoothly on crap phones on wp8.1, but highend phones on win10 lags....
Thanks microsoft for taking a change :/4 -
Oh hell yeah. I just spent a good few hours optimizing an ok mySQL query and made it so much better and faster. Inner join ftw!!3

I'm taking a vacation in two weeks to hopefully recover from this burnout. I don't know if I can make it that long.
I've been trying to work on a ticket for the past two days. I don't even know what the ticket says. Just something about optimizing the Google pay object api. idk. I just can't. I need to have it done today though. Bleh.7 -
Hello guys. Today I bring you my list of top 3 programs that use too much memory
🪟 Windows 10+
⚛️ Web browsers, Electron
🐋 Docker containers
Honorable mention: ☕Java
The developers of those programs should put more effort into optimizing memory usage14 -
As much fun it is to code and create new features for users. Take a break from the computer and spend time with real people.
A few years ago I would stay at work to get tasks done. While everyone in the office would go home I would stay and finish some task. After doing that for a few months my wife started to yell at me.
It made me realize that no matter how important a new feature, a bug or optimizing code is family and the relationships you have are more important.4 -
My boss's SQL schema has no foreign keys and he said he left them out intentionally because they should be handled in the application layer and they're a large performance impact.
This is a fresh greenfield project and he's already pre-optimizing for problems we don't have yet, on things that may or not be bottlenecks using ideas (e.g. foreign keys have huge performance costs on mariadb/auora) with no hard data or facts to back them up.
Let's start a new project with some technical debt!2 -
Proudest bug squash? Probably the time I fixed a few bugs by accident when I was just trying to clean up an ex-coworker's messy code.
So I used to work with a guy who was not a very good programmer. It's hard to explain exactly why other than to say that he never really grew out of the college mindset. He never really learned the importance of critical thinking and problem-solving. He did everything "by the book" to a point where if he ran into an issue that had no textbook solution, he would spin his wheels for weeks while constantly lying to us about his progress until one of us would finally notice and take the problem off his plate. His code was technically functional, but still very bad.
Quick Background: Our team is responsible for deploying and maintaining cloud resources in AWS and Azure. We do this with Terraform, a domain-specific language that lets us define all our infrastructure as code and automate everything.
After he left, I took on the work to modify some of the Terraform code he'd written. In the process, I discovered what I like to call "The Übervariable", a map of at least 80 items, many of them completely unrelated to each other, which were all referenced exactly once in his code and never modified. Basically it was a dynamic collection variable holding 80+ constants. Some of these constants were only used in mathematical expressions with multiple other constants from the same data structure, resulting in a new value that would also be a constant. Some of the constants were identical values that could never possibly differ, but were still stored as separate values in the map.
After I made the modification I was supposed to make, I decided I was so bothered by his shitty code that I would spend some extra time fixing and optimizing it. The end result: one week of work, 800 lines of code deleted, 30 lines added, and a massive increase in efficiency. I deleted the Übervariable and hardcoded most of the values it contained since there was no possible reason for any of them to change in the future. In the process, I accidentally fixed three bugs that had been printing ominous-sounding warnings to the console whenever the code was run.
I have a lot of stories about this guy. I should post some more of them eventually.2 -
just might have optimised myself away by recommending a software to my boss which does 90% of the tools i'm maintaining right now...wondering if i will still be in this chair next year3

I found a bug.... it's in production for a long long time... I wrote it while optimizing some legacy code....
FUCK.... how do you feel when you discover a bug in production created by you?6 -
For starters this is my first post, found devrant the other day you're all hilarious.
I hate math, I hate proofs. I'm in a class "Analysis of Algorithms" and I have understood and do understand the importance of optimizing algorithms and data structures and I understand the algorithms and data structures themselves. That being said, I'm fucking sick of math and proofs and all this bullshit that is probably pretty important but ugggghh, I guess I just have to push through, but writing this out helped.14 -
So, depression, yeah?
Two good days of work in a row, and on the third, I sleep late and think during sleep and throughout the night, wake up tired and feel shitty and feel a crash-burn in my feelings. (or whatever you want to call it. Burnt out? Tired? Exhausted? Lonely?) So now I have the rest the optimizing sql bullshit project and a paper to finish, plus I need to work more on the thesis. And ofc, work itself.
Everything feels so gloomy.
I know it gets better, but feeling shit doesn't help either.
Anyways, I'm fishing for attention this time so gimme your good vibes! 🙂4 -
I often read articles describing developer epiphanies, where they realized, that it was not Eclipse at fault for a bad coding experience, but rather their lack of knowledge and lack of IDE optimization.
No. Just NO.
Eclipse is just horrendous garbage, nothing else. Here are some examples, where you can optimize Eclipse and your workflow all you like and still Eclipse demonstrates how bad of an IDE it is:
- There is a compilation error in the codebase. Eclipse knows this, as it marks the error. Yet in the Problems tab there is absolutely nothing. Not even after clean. Sometimes it logs errors in the problems tab, sometimes t doesn't. Why? Only the lord knows.
- Apart from the fact that navigating multiple Eclipse windows is plain laughable - why is it that to this day eclipse cannot properly manage windows on multi-desktop setups, e.g. via workspace settings? Example: Use 3 monitors, maximize Eclipse windows of one Eclipse instance on all three. Minimize. Then maximize. The windows are no longer maximized, but spread somehow over the monitors. After reboot it is even more laughable. Windows will be just randomly scrabled and stacked on top of each other. But the fact alone that you cannot navigate individual windows of one instance.. is this 2003?
- When you use a window with e.g. class code on a second monitor and your primary Eclipse window is on the first monitor, then some shortcuts won't trigger. E.g. attempting to select, then run a specific configuration via ALT+R, N, select via arrows, ALT+R won't work. Eclipse cannot deal with ALT+R, as it won't be able to focus the window, where the context menus are. One may think, this has to do with Eclipse requiring specific perspectives for specific shortcuts, as shortcuts are associated with perspectives - but no. Because the perspective for both windows is the same, namely Java. It is just that even though Shortcuts in Eclipse are perspective-bound, but they are also context-sensitive, meaning they require specific IDE inputs to work, regarldless of their perspective settings. Is that not provided, then the shortcut will do absolutely nothing and Eclipse won't tell you why.
- The fact alone that shortcut-workarounds are required to terminate launches, even though there is a button mapping this very functionality. Yes this is the only aspect in this list, where optimizing and adjusting the IDE solves the problem, because I can bind a shortcut for launch selection and then can reliably select ant trigger CTRL+F2. Despite that, how I need to first customize shortcuts and bind one that was not specified prior, just to achieve this most basic functionality - teminating a launch - is beyond me.
Eclipse is just overengineered and horrendous garbage. One could think it is being developed by people using Windows XP and a single 1024x768 desktop, as there is NO WAY these issues don't become apparent when regularily working with the IDE.9 -
probably gonna have to do with environmental software certification (optimizing for energy reduction, that sort of stuff)15

Day 1:
Optimizing huge problems for the company. Get mail. *sigh*; Why is your script using up half the CPU on our thin clients? *place in complaints folder and go on*
Day 2:
Boss asks about it during scrum meeting. *Oh shits*
Need a cluster. Been asking for it for months...
Day 3:
Start runs on all thin clients. *Thou shall feel my wrath*
Complaints folder floods.
Day 4:
Expect rage from boss.
"IT seems to have found a cluster for you at last."

How do I make my manager understand that something isn’t doable no matter how much effort, time and perseverance are put into it?
———context———
I’ve been tasked in optimizing a process that goes through a list of sites using the api that manage said sites. The main bottle neck of the process are the requests made to the api. I went as far as making multiple accounts to have multiple tokens fetch the data, balance the loads on the different accounts, make requests in parallel, make dedicated sub processes for each chunks. All of this doesn’t even help that much considering we end up getting rate limited anyway. As for the maintainer of the API, it’s a straight no-can-do if we ask to decrease the rate limit for us.
Essentially I did everything you could possibly do to optimize the process and yet… That’s not enough, it doesn’t fit the 2 days max process time spec that was given to me. So I decided I would tell them that the specs wouldn’t match what’s possible but they insist on 2 days.
I’ve even proposed a valid alternative but they don’t like it either, admittedly it’s not the best as it’s marked as “depreciated” but it would allow us to process data in real time instead of iterating each site.3 -
At what point do you stop optimizing queries and realize it's a database architecture, scaling problem?
We've been having production issues this week because a lot more users with more demands, and I'm going we need more servers... We can't just have one db, we need to parallelize like Hadoop...
Everyone else is going, how do we optimize queries, indexes, reduce the load...11 -
Oh how I miss straight forward programming. I've been working on performance enhancements for a month. Optimizing angular is no fun.

One poor pepega like me will spend days optimizing a web app, reducing the bundle size, reusing components as much as possible to save space, carefully choosing the right libraries for the right jobs and doing some careful tayloring to bring them in line with your needs, choosing the right webpack plugins to compile everything exactly like you want and keeping track of every dependency to make sure nothing unwanted makes its way to the final product, caching results to avoid any unnecessary call to the server, then some random team leader randomly forces you to drop in jquery-era plugins just because they look nice and won't listen to a word you're saying.
I KNOW WHAT THE FUCK IS A SWEET ALERT; I DIDN'T USE IT FOR A FUCKING REASON.2 -
FredBoat, largest open source discord bot.
Making all the things work + making it scale when demand kept climbing was a challenge where we had to learn simple stuff like postgres, working with 3rd party apis, generally good coding patterns and maintainable code, but also rather advanced stuff like making the garbage collector play nice, profiling memory leaks and optimizing the hot path, as well as high level topics like cutting the codebase into scalable domains and services. -
So I start developing a site for a client and request for the site assets.. Client provides 100+ 25mb sized .tiff images.... For the web! I tell him that the page load times will be insanely slow and I explain the need for optimized images.. He doesn't care.. So I upload the images and he flips out at the performance hit, complaining about the slow load times.. Here I am sitting and optimizing the images when I should be home :/1

Recently I see people installing Linux distros to their Macbooks. Is MacOS that bad? I mean I use Ubuntu in my daily life but let's accept that most of the Linux distros (for desktop of course) has hickups. I haven't used MacOS but there is a big company maintaining and optimizing it for just few machines. What is the point installing a Linux distro to a Mac?6

Computer science vs software engineering?
Software engineering is all about people. You have to communicate with the business, realizing their needs, figuring out their processes, optimizing them, all this before the first line of code is written. Then, you have to manage your direct reports, and if you have none, write code with people in mind, people who will read it after you. As they say, code is for people, not for computers. Then, you have to improve the app listening to users, again, people.
I can’t assign a software engineer a role higher than middle if they’re bad with people.
If you wanna do cool stuff with computers and be a misanthrope, do computer science! It’s a very prestigious field where you are left alone with scary math and fundamental concepts. If you’re successful there, you’ll have a mad asocial scientist card, and no one will ever insist to you that people is important. They will just accept that they shouldn’t annoy you, and you are “allowed” to yell at them because you’re “special” and a “genius”. You can hate them 24/7.1 -
In my experience, any BE dev or old architect/lead programmer that says they “can do frontend” does shit like writing Ajax calls in script tags directly in the html. They are the ones who add style attributes directly in html. They are the ones who google how to center a div and they still use float positioning because all of them are old, arrogant BE devs who get caught in a single framework who convince themselves they are an expert. They can’t give any good UX advice. They don’t know how to use a screen reader. They don’t know what WCAG means. They don’t constantly keep up to date on what browsers are supporting and what’s being released in the unstable versions. They don’t know what a web component is. They don’t know what a closure is. They don’t know anything about optimizing web perf metrics. They couldn’t tell you what web crawlers look for. They couldn’t tell you anything about design principles and anti-patterns. They don’t know how to manage a web application that will be seen by millions AND keep it nice, shiny, and refactorable on the code side. What do they really fucking know? how to write an MVC app? How to connect APIs and integrate code that other people wrote? I do full stack all day and writing anything not-client-facing is super easy.
Take that stick out of your ass and get over yourself you asshole. You haven’t written anything close to amazing even though you constantly act like you’re a god-tier programmer and your shit doesn’t stink.
Hit the books like the rest of us you fuck.
The Frontend is anything but fucking easy.25 -
Optimizing JS is such a pain. like, the total runtime of the rest of the code is not measurable compared to DOM operations, so the goal would be to optimize DOM access, but there are zero resources online on the relative cost of certain operations, and I get the feeling that they don't have much in common across browsers.2

I know recursion is everywhere but I recently noticed it in very unusual place('unusual' in the way we see), I hail from India, we studied in our childhood about road less taken, the way I see, everyone has to take so important decisions in yheir life, one such decission is about career, in India road less taken in career paths is everything other than orthodox education, I too the dreaded road "Education", next decission is to choose stream and there the road less taken is anything other that "Engineering (or medicne) " and I took (*as expected) engineering, after taking computers (which is the dreaded road now) next decision is what next? Dreaded road is job, but this time I chose take a road little less traveled in CS. Then I next decission was to choose the research stream the road less taken here (NOW) is systems as AI is in its prime and everyone whants to ride the wave, but I chose Systems in research, after all these my point how how boolean function is called recursively (in the sense of construct) and as a systems programmer I realize the importance of optimizing how I answer these functions quick and accurate. This is one such boolean function but I am sure you can find many in our path till here so It is better to realize what these functions are optimize then as a good Programmer of your own Life.

To all that read my rants regarding my webshop before! Here's the long awaited update!
So this asshole partner did just not take care of business so I decided to stand down as a director for that company. So we arranged that last monday.
I thought: let's end this properly, clean up my mail, some other stuff... tuesday he revoked me access to everything, so I couldn't access anything anymore. Wow fucker! You never did a thing and now suddenly you take action? Wtf?!
Can you please pay your part of the bill for the accountant? You already promised a couple of times.
Well of course mr retard, you really think I'll follow up on my promises? You never kept 1 of them yet expect me to keep that promise? Fuck you man.
So today he asked again. I told him that I'd like to know what he wants with all the custom made stuff as I developed it and copyright is owned by me. Then mr asshole started insulting again: just because of the fact that you're not a front end dev doesn't mean that makes.up for you taking so much time.to implement all that. I asked an expert.and he could do it in 3 hours! Wow dude! A front end dev optimizing db queries, rewriting parts of the back end in just.3 hours including the front-end?,You're so right.
Of course not cunt face. I'm already full stacking for 20 fucking years and.you tell me that?! Really? Mr insult's back again!
Then he says: I'm so fed up with all this crap that to end this properly I will have my new IT business partner look at your so called 'custom made components'.
For fuck's sake man, can I send you a tree with a rope so that you can hang yourself?
Good luck getting your domain name as it is still registered on my company's name. I might cancel it someday in the future at my convenience.
If anyone here loves fucking up a website, get in touch with me.1 -
I have been spending all day optimizing a wordpess site for pagespeed, looking into how can I optimize the custom scripts which block rendering and I was learning some new things, it was hard but I was making progress. Then comes the senior engineer who installs a plugin and pagespeed went from 60 to 90 on mobile, I was pretty shocked. Then it hit me. IT DELAYS THE LOADING OF EVERY SCRIPT AND IMAGE UNTIL USER INPUT TRICKING THE SCORING SYSTEM. U GET A WHITE SCREEN IF YOU DON'T DO ANYTHING. I told him it's not really faster this way, and he agreed it is not "ethical" but the score is good.
Am I still an idiot naive kid? There is a line between scamming people and quality work, but it keeps getting more blurry.5 -
Genuinely wondering if there's some agenda to keep people employed by not optimizing certain workflows because the client is so big it doesn't matter 😂2

PMs are strange. I spend over a year to perfect a self optimizing, state agnostic End2End test with almost no flakyness and they're like "Yeah, nice". I write a frickin 15 line php script to display in which translation file a certain string is defined and they act as if I'd just walked over water.

You ever sit down to code, all pumped up and ready to conquer the digital world, only to have your computer decide it's the perfect time to install updates? "Sorry, can't work right now, I'm busy optimizing your experience," it says, while you sit there twiddling your thumbs and wondering who asked for this update in the first place.
And let's talk about variable names. Who thought naming things would be the hardest part of programming? You start with `count` and `index`, but by the end of the project, you're using variables like `reallyLongVariableNameThatDescribesExactlyWhatThisThingDoes`. It's like playing a game of how many characters can you type before your fingers revolt.
Then there's the joy of debugging. You sprinkle `console.log()` like breadcrumbs through your code, trying to find where things went off the rails. Half the time, you realize you've been chasing the wrong rabbit down the wrong hole, and the other half, you discover the bug is some obscure edge case that you couldn't have predicted in a million years.
But hey, it's not all doom and gloom. There's a weird satisfaction in solving those coding puzzles, like when you finally get that algorithm to work or refactor your code into something so elegant, it feels like you've sculpted a masterpiece out of digital clay.
So here's to all the coders out there, navigating the ups and downs of curly braces and semicolons with a mix of determination and exasperation. May your code compile, your bugs be minor inconveniences, and your computer never decide to update right when you're on a coding roll!!3 -
I just love optimizing stuff and here is my story I think somehow is very cool as you can see the progress just looking at two values.
//NOTE: This api relies on another api which is slow af. The requests are done here directly but later will be carried out async and in the background by using some ticket system.
1) First PoC
2) Used caching of requests and improved method to filter out unnecessary stuff
3) Optimized response formatting
NOTE to myself: Things are going too good...4 -
Just ordered my first ssd as a sort of self-reward for managing to get my groups project to get the 2nd highest score in class after many sleepless nights refactoring and optimizing the codebase
Honestly I’d have been happy with a C just so I passed the damn class. But my individual grade was an A and the group’s collective grade was a 86. The second highest group grade in class2 -
Optimizing my RESTful API plugin, used in a CMS to make it headless, was extremely satisfying.
Thanks to caching and alorithm improvements, I brought the response times down by a factor of 150.
The caching also includes dependency tags thus it will automatically invalidate on changes in the dependent element.1 -
Spent 2 days optimizing SQL queries, and then I learned a valuable lesson.
If your database size is bigger than the RAM of the machine it’s running on, every query will take 5+ seconds ☹️4 -
Monday morning after working whole weekend to finish for release at Tuesday tidying everything up, optimizing, when I ask myself
"why did I wrote in ES5?"
*Checking the time*
"17 hrs left of this day, I should be able to make it!"
As if I didn't have enough problems with procrastination in my life. I sure can find more things to do
*Locking the door and turning phone off* -
Joke about Rust all you want, but Rust is the reason efficient programs are on vogue. When you see a web developer optimizing their JavaScript to make a smaller bundle, or a backend developer getting rid of dependencies, thank Rust for that.
I don't like Rust, I don't like their community, I don't like their superiority complex, but their existence is net positive so far.9 -
In the past, apps I've written have used a flat file backend. It's very fast, but obviously clunky to have a big structure of flat files for an app. It ran circles around framework-based RDBMS backends, as performance is concerned, but again, it was clunky. Managing backups and permissions on tens or hundreds of thousands of small files was no fun. Optimizing code for scaling was fun- generating indexes, making shortcuts -but something was still missing. Early in 2017 I discovered redis. A nosql backend that just stores variables and lives almost entirely in memory. Excellent modules and frameworks for every language. It was EXACTLY what I'd needed, even though I didn't know I did. I spent a good deal of time in 2017 converting apps from flat files to redis, and cackled with glee as they became the apps I wanted them to be. Earlier this week, I started building my first app that started with redis, instead of flat files, and I can't stop gushing to anyone who will listen. Redis for president!

Does the windows "optimization" feature which apparently is defragmenting in the background, and apparently "optimizing" ssd's differently of any use? The only thing I notice is that this function makes the icons of my desktop reload on a regular basis. My guts tell me it's utter bs and is just slowing down the system.
Any experiences, optinions, thoughts?6 -
There are so many.. but probably my worst was when I was building this project and optimizing it for mobile but for some reason when in mobile view, there was a slight white line on the right side when swiping right or zooming out (shouldnt be able to zoom out either).. checked all the media queries and viewport code and everything was normal so it drove me crazy for a few hours. Turns out, I had 1 little element slightly wider than the viewport but you couldnt tell by looking at it xD fixed the css, but still so frustrating.1

So, our lab professor in university for data structures was evaluating my friend's group assignment next to me and my colleague.
Professor: So, what does this method do?
Friend: I feel it would be best to explain our structure first and then how our methods work.
P: No, no. It's okay, I'm seeing it here in my laptop. *Looking at their report which included nothing about the structure of the assignment since she asked specifically only to place the methods and their complexity analysis due to not having time to look and evaluate a full report for each group*
F: Okay, *proceeds to explain*.
P: Okay, and why is your code commented?
F: Because it's good practice and we learned in subject x last semester.
P: Impossible! I teach that subject and I did not teach that in my classes.
F: Okay, but our professor did.
P: *Says nothing*.
They got a 3.25/5 as a grade for it and got really pissed off. I mean, they spent a lot of time making the assignment's structure perfect, optimizing their code and the professor did not care for the structure, just the methods, on the data structures subject.
FYI, they are workaholic, dedicate a lot of time improving their skills and their normal grades are usually >= 4.25.2 -
I wonder if anyone has considered building a large language model, trained on consuming and generating token sequences that are themselves the actual weights or matrix values of other large language models?
Run Lora to tune it to find and generate plausible subgraphs for specific tasks (an optimal search for weights that are most likely to be initialized by chance to ideal values, i.e. the winning lottery ticket hypothesis).
The entire thing could even be used to prune existing LLM weights, in a generative-adversarial model.
Shit, theres enough embedding and weight data to train a Meta-LLM from scratch at this point.
The sum total of trillions of parameter in models floating around the internet to be used as training data.
If the models and weights are designed to predict the next token, there shouldn't be anything to prevent another model trained on this sort of distribution, from generating new plausible models.
You could even do task-prompt-to-model-task embeddings by training on the weights for task specific models, do vector searches to mix models, etc, and generate *new* models,
not new new text, not new imagery, but new *models*.
It'd be a model for training/inferring/optimizing/generating other models.4 -
So the last couple of days I have been optimizing my site, from a Pagespeed score below 40 to 97 and I can't get further because I'm using Google Analytics, Facebook Like-button and load a couple of images from Youtube.
Why must you be like this Google 😥😥It's partly you code, so why are you punishing me 😥1 -
I'm wondering if there is a way to use Machine Learning algorithm to optimize games like Screeps.com, which is a game that you control your game by writing JS code. Letting the algorithm write human readable code might be too challenging, but optimizing some aspect of the game should be possible, like the best scale up route optimization using re-enforced learning.3

Worst project I worked on was fixing up and optimizing a clients legacy Magento app. this thing had leftover code from a few different development teams, and then my company had to make it run better. We outsourced much of it, and it wasn't using a proper git setup. in order to do absorb at all, we had to SSH to a dev server, work directly, and pray another person on the team want working on the same file or breaking something else.1

I need some advice to avoid stressing myself out. I'm in a situation where I feel stuck between a rock and a hard place at work, and it feels like there's no one to turn to. This is a long one, because context is needed.
I've been working on a fairly big CMS based website for a few years that's turned into multiple solutions that I'm more or less responsible for. During that time I've been optimizing the code base with proper design patterns, setting up continuous delivery, updating packaging etc. because I care that the next developer can quickly grasp what's going on, should they take over the project in the future. During that time I've been accused of over-engineering, which to an extent is true. It's something I've gotten a lot better at over the years, but I'm only human and error prone, so sometimes that's just how it is.
Anyways, after a few years of working on the project I get a new colleague that's going to help me on my CMS projects. It doesn't take long for me to realize that their code style is a mess. Inconsistent line breaks and naming conventions, really god awful anti-pattern code. There's no attempt to mimic the code style I've been using throughout the project, it's just complete chaos. The code "works", although it's not something I'd call production code. But they're new and learning, so I just sort of deal with it and remain patient, pointing out where they could optimize their code, teaching them basic object oriented design patterns like... just using freaking objects once in a while.
Fast forward a few years until now. They've learned nothing. Every time I read their code it's the same mess it's always been.
Concrete example: a part of the project uses Vue to render some common components in the frontend. Looking through the code, there is currently *no* attempt to include any air between functions, or any part of the code for that matter. Everything gets transpiled and minified so there's absolutely NO REASON to "compress" the code like this. Furthermore, they have often directly manipulated the DOM from the JavaScript code rather than rendering the component based on the model state. Completely rendering the use of Vue pointless.
And this is just the frontend part of the code. The backend is often orders of magnitude worse. They will - COMPLETELY RANDOMLY - sometimes leave in 5-10 lines of whitespace for no discernable reason. It frustrates me to no end. I keep asking them to verify their staged changes before every commit, but nothing changes. They also blatantly copy/paste bits of my code to other components without thinking about what they do. So I'll have this random bit of backend code that injects 3-5 dependencies there's simply no reason for and aren't being used. When I ask why they put them there I simply get a “I don't know, I just did it like you did it”.
I simply cannot trust this person to write production code, and the more I let them take over things, the more the technical debt we accumulate. I have talked to my boss about this, and things have improved, but nowhere near where I need it to be.
On the other side of this are my project manager and my boss. They, of course, both want me to implement solutions with low estimates, and as fast and simply as possible. Which would be fine if I wasn't the only person fighting against this technical debt on my team. Add in the fact that specs are oftentimes VERY implicit, so I'm stuck guessing what we actually need and having to constantly ask if this or that feature should exist.
And then, out of nowhere, I get assigned a another project after some colleague quits, during a time I’m already overbooked. The project is very complex and I'm expected to give estimates on tasks that would take me several hours just to research.
I'm super stressed and have no one I can turn to for help, hence this post. I haven't put the people in this post in the best light, but they're honestly good people that I genuinely like. I just want to write good code, but it's like I have to fight for my right to do it.1 -
I try (and sometimes fail) to be open to new suggestions.
And I'm trying to be more versatile with the languages that I write in. E.g. instead of optimizing that small python script, I'll practice my Go skills -
The nice thing about my current side project is that I don't have to care at all about optimizing. It takes 5 seconds for the motors to do their thing and I spend 95% of that waiting even with my horribly slow (but easy to write) code.1

[POLL] How do you develop stuff?
1 - just write code. It doesn't need to be organized, it just need to work how you thought it would, and THEN you start organizing things, like editing/creating new files, letting things DRY, optimizing the sutff you did earlier;
OR
2 - you surgically write code, making sure you keep everything is organized from the beginning. Basically you only write when you are sure.
Or maybe it's a blend between the two or something.
I'm asking because I do like the #1 and I feel uncomfortable when people see my code when it's under development. It's a mess, there are tons of comments everywhere and a bunch of repetition. But, when I find the right stuff, I start writing modules to make my code work better, remove unnecessary things, add documentation, and so on.
My development process is not the best of the best, but I get things done with it.7 -

I could go programming drones to kill my own people for money, like at least then I'd have a connection to my job
also programming drones sounds kind of fun
I used to really like pvp games. I also love unconventional RTS games. who wouldn't wanna make a real-world pvp RTS game interface, or automate an army of autonomous drones that could act on their own like it's a game of screeps
literally just so fun
if I was @ostream and an accelerationist...
either case if I go work somewhere and build them something great I have weird confusing PTSD emotions about it. to be honest making war machines somehow makes me less anxious about the idea. isn't it strange. I can't figure it out
you help people but they fuck you. at least if you're fucking people you'd accept being fucked in the process so you don't end up feeling anxious? I don't know why I feel like I do
you'd expect if you help people they would help you back. then when they don't it ruins everything, it ruins your core. you also can't know if who you are committing to will help you back or not. so you can only lose. if you help you'll get fucked. so why help?
in which case just doing something you love like optimizing pwn machines is what I'm built for. is that all I got? how does that make sense? it just doesn't to me. you'd think it would be clear but something is fighting -

That feeling when you're optimizing your code and comment a small function to compare results, then few hours later you push to production and forget everything about that function.
It aint pretty, nope I can't run away from this one!2 -

Design in Motion: Real-Time Rendering's Impact on Architecture
Architecture, a discipline that once relied heavily on blueprints, models, and lengthy render times, has undergone a revolutionary transformation in recent years. The advent of real-time rendering technology has fundamentally altered the way architects visualize, present, and interact with their designs. This paradigm shift has not only enhanced the creative process but has also empowered architects to make more informed decisions and create immersive experiences for clients and stakeholders.
Real-time rendering, a technological marvel that harnesses the power of high-performance graphics hardware and advanced software algorithms, allows architects to generate photorealistic visualizations of their designs in a matter of milliseconds. Gone are the days of waiting hours or even days for a single rendering to complete. This acceleration in rendering time has not only expedited the design process but has also encouraged architects to explore multiple design iterations rapidly.
One of the most significant impacts of real-time rendering on architecture is the ability to visualize a design in various lighting conditions and environmental settings. Architects can now instantly switch between daytime and nighttime lighting scenarios, experiment with different materials, and observe how their designs respond to different seasons or weather conditions. This level of dynamic visualization offers insights into how a building's appearance and functionality evolve throughout the day, contributing to more holistic and thoughtful design solutions.
Moreover, real-time rendering has transformed client presentations. Architectural concepts can now be communicated with unprecedented clarity and realism. Clients can virtually walk through spaces, observing intricate details, exploring different angles, and even experiencing the play of light and shadow in real-time. This immersive experience fosters a deeper understanding of the design intent, enabling clients to provide more targeted feedback and make informed decisions.
The impact of real-time rendering on collaboration within architectural teams cannot be overstated. Traditionally, architects and designers would need to wait for a rendering to complete before discussing design changes or improvements. With real-time rendering, team members can make adjustments on the fly, observing the immediate effects of their decisions. This seamless collaboration not only enhances efficiency but also encourages interdisciplinary collaboration as architects, engineers, and other stakeholders can work together in real-time to refine designs.
The integration of virtual reality (VR) and augmented reality (AR) into the architectural workflow is another transformative aspect of real-time rendering. Architects can now create VR environments that allow clients to step inside their designs and explore every nook and cranny. This not only enhances client engagement but also enables architects to identify potential design flaws or spatial issues that might not be apparent in 2D drawings. AR, on the other hand, overlays digital information onto the physical world, facilitating on-site decision-making and construction supervision.
Real-time rendering's impact extends beyond the design phase. It has proven to be a valuable tool for public engagement and community involvement in architectural projects. By creating virtual walkthroughs of proposed structures, architects can offer the public an opportunity to experience the design before construction begins. This transparency fosters a sense of ownership and allows for constructive feedback, contributing to the development of designs that resonate with the community's needs and aspirations.
The environmental implications of real-time rendering are also noteworthy. The ability to visualize designs in various environmental contexts contributes to more sustainable architecture. Architects can assess how natural light interacts with interior spaces, optimizing energy efficiency and reducing the need for artificial lighting during the day.
In conclusion, real-time rendering has ushered in a new era of architectural design, propelling the industry into a realm of dynamic visualization, immersive experiences, and enhanced collaboration. The ability to witness designs in motion, explore different lighting conditions, and interact with virtual environments has redefined how architects approach their craft. From facilitating client presentations to fostering sustainable design solutions, real-time rendering's impact on architecture is profound and multifaceted. As the technology continues to evolve, architects have an unprecedented opportunity to push the boundaries of creativity, efficiency, and sustainability in the built environment. -

Apparently Android Pay released for Canadians some time ago, because it's on the front page of the google play store. I really want to use it cause remembering to carry a card around is tough work, but I'm failing the safetynet check.
My only choice, it seems is to revert to a system where I don't have root. I was thinking of installing lineageos, but I'd be giving up some pretty serious things that I've gotten into with Resurrection Remix.
The fling navbar would be gone, I'd probably be able to deal with that but I just find it a way nicer experience than the traditional android navbar.
I might not be able to use Google Assistant, not sure if Lineage has it
And (worst of all), if I revert to a system without root, I won't be able to use my system-wide dark mode from substratum (I'd also be losing battery optimizing features from greenify, which is just another downside)
Existing Android Pay users, is this worth it?10 -

My company wanted me to make a signature for the google mail employee accounts but google said its too long even though the limit is at 10,000 symbols and it only had 300 letters visble with 3 images. Then I realized that google counts all the html stuff as symbols. I spent the entire day on optimizing the signature and wondering why it didnt fuckn work until I sent an email with a shorter version and looked at the source code. 9000 symbols. What the fuck google. No more computer stuff for today. Brain is #Fried
