You know who sucks at developing APIs?
Facebook.
I mean, how are so high paid guys with so great ideas manage to come up with apis THAT shitty?
Let's have a look. They took MVC and invented flux. It was so complicated that there were so many overhyped articles that stated "Flux is just X", "Flux is just Y", and exactly when Redux comes to the stage, flux is forgotten. Nobody uses it anymore.
They took declarative cursors and created Relay, but again, Apollo GraphQL comes and relay just goes away. When i tried just to get started with relay, it seemed so complicated that i just closed the tab. I mean, i get the idea, it's simple yet brilliant, but the api...
Immutable.js. Shitload of fuck. Explain WHY should i mess with shit like getIn(path: Iterable<string | number>): any and class List<T> { push(value: T): this }? Clojurescript offers Om, the React wrapper that works about three times faster! How is it even possible? Clojure's immutable data structures! They're even opensourced as standalone library, Mori js, and api is great! Just use it! Why reinvent the wheel?
It seems like when i just need to develop a simple react app, i should configure webpack (huge fuckload of work by itself) to get hot reload, modern es and jsx to work, then add redux, redux-saga, redux-thunk, react-redux and immutable.js, and if i just want my simple component to communicate with state, i need to define a component, a container, fucking mapStateToProps and mapDispatchToProps, and that's all just for "hello world" to pop out. And make sure you didn't forget to type that this.handler = this.handler.bind(this) for every handler function. Or use ev closure fucked up hack that requires just a bit more webpack tweaks. We haven't even started to communicate to the server! Fuck!
I bet there is savage ass overengineer sitting there at facebook, and he of course knows everything about how good api should look, and he also has huge ass ego and he just allowed to ban everything that he doesn't like. And he just bans everything with good simple api because it "isn't flexible enough".
"React is heavier than preact because we offer isomorphic multiple rendering targets", oh, how hard want i to slap your face, you fuckface. You know what i offered your mom and she agreed?
They even created create-react-app, but state management is still up to you. And react-boierplate is just too complicated.
When i need web app, i type "lein new re-frame", then "lein dev", and boom, live reload server started. No config. Every action is just (dispatch) away, works from any component. State subscription? (subscribe). Isolated side-effects? (reg-fx). Organize files as you want. File size? Around 30k, maybe 60 if you use some clojure libs.
If you don't care about massive market support, just use hyperapp. It's way simpler.
Dear developers, PLEASE, don't forget about api. Take it serious, it's very important. You may even design api first, and only then implement the actual logic. That's even better.
And facebook, sincerelly,
Fuck you.17 -
So we started a new Unity video game project for mobile in June 2021. Hooray!
Being a mobile project, one of the earliest things we think about is scaling the interface across all sorts of device screen resolutions and aspect ratios, right? Well, to preemptively solve this problem early on, I decided to letterbox the game view - just choose one aspect ratio for the game and pad black bars to the sides of the screen. Simple, solves the game's world space problem without trying too hard, and it automatically adapts to Android's split-screen mode.
I showed the early builds to management as well as game design team and they gave me some general nods. Sounds like green light ahead. I spent the next few months building the game logic and scale the UI around a consistent letterboxed game view. If you had experience scaling Unity UI to a letterboxed area, you should already knew that it takes a whole paradigm of its own that's kinda hard to break out of, but the fact that it stays consistent across all screen aspect ratios is so worth it. Regardless, the biggeer benefit of letterboxing is simpler world space setup. You don't worry about whether this particular area will be overflowed horizontally or vertically in a particular device or not. You have a 9:16 window to view the world through, nothing needs to move at runtime and that's about it.
Fast-forward to early September 2021 and 40+ builds later, the GD started having concern that the playing area is not filling up his phone screen and that the letterboxes are bothering him. He wants to get rid of the letterboxes and wants the game world as well as UI to fill up his screen.
Yes. After 40+ builds, for all of which the letterbox was present, nobody in the project raised a concern about the letterbox. It's only NOW that they all of the sudden side with the GD and demand the removal of the letterbox. I feel like almost half of my effort on this game has been wasted. These clueless guys didn't spend one second looking at the early builds thinking of the possibility that the black bars at the top and bottom of their phone screens (which I repeat: has been around since the very first build) is gonna bother them? Somebody must be playing a cruel joke at this company. They had all the chances to bring this up as a potential issue and TODAY is the first time I hear of it.
See, designers. You waste our time and your time by doing this kind of thing. Please raise your issues early. Complain to us ASAP. If you wait for so long before raising an issue that has been in-your-face the whole time, I can't fault any developer for assuming you're trying to play a long prank. I can tell designers right now: it's not funny.1 -
I was thinking about the problems one of our clients faced with the launch of their project the other day, because things were rushed, stuff was omitted and in the end they could not meet the launch date, and I started making a list of hard lessons I learned over the years that would have helped them avoid this situation.
Feel free to add yours in the comments.
- Never deploy on Friday
- Never make infrastructure changes right before a launch
- Always have backups. Always!
- Version control is never optional
- A missed deadline is better than a failed launch
- If everything is urgent, nothing is important
- Fast and cheap, cheap and quality, quality and fast. Only one pair at a time can be achieved
- Never rush the start or the end of a project
- Stability is always better that speed
- Make technical decisions based on the needs of the project two years from now
- Code like you will be the only maintainor of the project two years from now. You probably will...
- Always test before you deploy
- You can never have too many backups (see above)
- Code without documentation is a tool without instructions
- Free or famous does not necessarily mean useful or good
- If you need multiple sentences to explain a method, you should probably refactor
- If your logic is checked beforehand, writing the code becomes way easier
- Never assume you understand a request the first time around. Always follow up and confirm
There are many more that should be on this list, but this is what came to mind now.2 -
A noob here, please don't judge too hard.
My major is maths and philosophy(mainly doing logic in philosophy), and even though we had python in maths, it's so basic I don't even think I can say I learnt anything (sololearn on my phone taught me more lol)
Does anyone have experience of transferring to IT after or during a maths degree? Not rly asking for advice, just want to hear life experiences and maybe learn something!6 -

Battle of titans:
Me vs Windows Update.
No, this time not about automatic restarts interrupting my work because I've postponed "important" updates for far too long.
Well, technically I lied.
Last evening windows force rebooted to install updates. OK then, I'll go home. This morning I saw windows update frozen at some percentage.
This evening I've got 3 forced restarts in 5 minutes. Only notepad++ with an opened and unsaved document saved my life.
Apparently, windows update follows a simple logic:
if(user.IsUsingComputer && lastUpgradeAttempt.HasFailedWithTotalFreeze && versionUpgrade.CanInstallOnlyWithFreshWindowsInstallation)
{
update();
}
Seriosly. Why am I forced to install an update only to see it lock up the entire computer and rollback after I intervene? Last time I had this issue only reinstalling windows helped, which costs about 2 days. Excluding one day to try suggested solutions, remove drivers, av scanner, etc.
Is it really that hard to implement logic like:
If(lastUpdateAttempt.HasFuckedUp)
{
windowsUpdate.FuckOff();

A bit late.. and not much about how to learn to code..but more of a figuring out if the kid has a right mind set to do so..
If the kid is not the type to question everything, not resourceful, not a logical/critical thinker, gives up easily and especially if not interested in how things work then being a dev is most probably not for them.. they can still persue coding, but it will end badly..
From my experience, people who have a better education than me, but lack those skills turned out to be a crappy dev.. not interested in the best tool to complete the tasks, just making 'something', adding more shit to the already shitty stack.. and being happy with that.. which of course is not the best way to do things around here..or in life!!
Soo.. if the kid shows all that and most importantly shows interest in learning to code.. throw him the java ultimate edition book and see what happens.. joke!
There are plenty of apps thath can get you started (tried mimo, but being devs yourself it's probably not so hard to check some out and weed out the bad ones) that explain simple logic and syntax.. there is w3schools that explains basics quite well and lets you tinker online with js and python..
so maybe show them these and see what happens.. If it will pick their interest, they will soon start to ask the right questions.. and you can go from there..
If the kids are not the 'evil spawns' of already dev parents or don't have crazy dev aunties and uncles, then they will have to work things out themselves or ask friends... or seek help online (the resourceful part comes here).. so google or any flavour of search engines is their friend..
Just hope they don't venture to stack overflow too soon or they will want to kill themselves /* a little joke, but also a bit true.. */
Anyhow, if the kid is exhibiting 'dev traits' it is not even a question how to introduce it to the coding.. they will find a way.. if not, do not force them to learn coding "because it's in and makes you a lot of moneyz"..
As with other things in life, do not force kids to do anything that you think will be best for them.. Point them in direction, show them how it might be fun and usefull, a little nudge in the right direction.. but do not force.. ever!!!
And also another thing to consider.. most of the documentation and code is written in english.. If they are not proficient, they will have a hard time learning, checking docs, finding answers.. so make sure they learn english first!!
Not just for coding, knowing english will help them in life in general. So maaaaybe force them to learn this a bit..
One day my husband came to me and asked me how he can learn.. and if it's too late for him to learn coding.. that he found some app and if I can take a look and tell him what I think, if it is an ok app to learn..
I was both flattered and stumped at the same time..
Explained to him that in my view, he is a bit old to start now, at least to be competitive on the market and to do this for a living, but if it interests him for som personal projects, why not.. you're never too old to start learning and finding a new hobby..
Anyhow, I've pointed out to him that he will have to better his english in order to be able to find the answers to questions and potential problems.. and that I'm happy to help where and when I can, but most of the job will be on him.
So yeah, showed him some tutorials, explained things a bit.. he soon lost interest after a week and was mindblown how I can do this every day..
And I think this is really how you should introduce coding to kids.. show them some easy tutorials, explain simple logic to them.. see how they react.. if they pick it up easily, show them something more advanced.. if they lose interest, let them be.
To sum up:
- check first if they really want to learn this or this is something they're forced to do (if latter everything you say is a waste of everybodys time)
- english is important
- asking questions (& questioning the code) is mandatory so don't be afraid to ask for help
- admitting not knowing something is the first step to learning
- learn to 'google' & weed out the crap
- documentation is your friend
- comments & docs sometimes lie, so use the force (go check the source)
- once you learn the basics its just a matter of language flavour..adjust some logic here, some sintax there..
- if you're stuck with a problem, try to see it from a different angle
- debugging is part of coder life, learn to 'love' it4 -
WARNING - a lot of text.
I am open for questions and discussions :)
I am not an education program specialist and I can't decide what's best for everyone. It is hard process of managing the prigram which is going through a lot of instances.
Computer Science.
Speaking about schools: regular schools does not prepare computer scientists. I have a lot of thoughts abouth whether we need or do NOT need such amount of knowledge in some subjects, but that's completely different story. Back to cs.
The main problem is that IT sphere evolves exceedingly fast (compared to others) and education system adaptation is honestly too slow.
SC studies in schools needs to be reformed almost every year to accept updates and corrections, but education system in most countries does not support that, thats the main problem. In basic course, which is for everyone I'd suggest to tell about brief computer usage, like office, OS basics, etc. But not only MS stuff... Linux is no more that nerdy stuff from 90', it's evolved and ready to use OS for everyone. So basic OS tour, like wtf is MAC, Linux (you can show Ubuntu/Mint, etc - the easy stuff) would be great... Also, show students cloud technologies. Like, you have an option to do *that* in your browser! And, yeah, classy stuff like what's USB and what's MB/GB and other basic stuff.. not digging into it for 6 months, but just brief overview wuth some useful info... Everyone had seen a PC by the time they are studying cs anyway.. and somewhere at the end we can introduce programming, what you can do with it and maybe hello world in whatever language, but no more.. 'cause it's still class for everyone, no need to explain stars there.
For last years, where shit's getting serious, like where you can choose: study cs or not - there we can teach programming. In my country it's 2 years. It's possible to cover OOP principles of +/- modern language (Java or C++ is not bad too, maybe even GO, whatever, that's not me who will decide it. Point that it's not from 70') + VCS + sime real world app like simplified, but still functional bookstore managing app.
That's about schools.
Speaking about universities - logic isbthe same. It needs to be modern and accept corrections and updates every year. And now it depends on what you're studying there. Are you going to have software engineering diploma or business system analyst...
Generally speaking, for developers - we need more real world scenarios and I guess, some technologies and frameworks. Ofc, theory too, but not that stuff from 1980. Come-on, nowadays nobody specifies 1 functional requirement in several pages and, generally, nobody is writing that specification for 2 years. Product becomes obsolete and it's haven't even started yet.
Everything changes, whether it is how we write specification documents, or literally anything else in IT.
Once more, morale: update CS program yearly, goddammit
How to do it - it's the whole another topic.
Thank you for reading.3 -
Having a hard time thinking the alternates to if statements is a good idea. I was genuinely curious how this was done. The examples I am finding seem to just spread the logic everywhere across multiple objects. To me this makes the logic objectively less clear. I didn't understand the obsession with objects until I saw the examples that creates a fuckton of boiler plate objects. How someone can say this is preferred over a few if statements boggles my mind. I actually am trying to understand the functional mindset as well. It is not going well for me. I can sorta see some value in using a map. Technically a lookup could be faster. But again it spreads the code all around adding more boilerplate.
https://blog.bitsrc.io/reduce-if-el...
https://dev.to/phouchens/...
Is it because these are contrived examples? I initially searched to find ways of reducing ifs in a functional approach. I did find it in the second example. I was however hoping to find that by lazy eval or something. I see people making references to how one you "get it" functional logic is easier to understand and evaluate. I cannot tell if this is straight up gaslighting or my brain is just too fucking imperative.11 -
I need to add new feature into the program which I wrote years ago so I start digging up the source code. The project is written in a language which I no longer code in.
That code is really poorly written with most of them don't have tests. I also find out that previous self is really a genius since he can keep track of huge project with almost no documentation.
To make matter worst, there are unused components (class,feature) in the source code. "Current me" have a policy of "just adding only a feature you need and remove unused feature" but it seem the "previous me" don't agree with the "current me".
The previous me also have the habit of using writing insane logic. I can remember what particular class and methods is doing but I can't figure out the details.
For example one method only have 5 line of code but it is very hard to figure out what those do.
The saving grace is that he know the important for method signature and using immutable data structure everywhere.
I was under the influence of caffeine and have a constant sleep deprivation at the time (only sleeping about 4 hour every day) so I can't blame him too hard.
I can't blame him too hard, right?
Could someone invent a time machine already? Invent time machine not to save the world but to save the developers from himself.4 -
I'm just fed up with the industry. There are so much stupidity and so much arrogance.
My professional experience comes mainly from the frontend and I feel like it's not as bad on the backend but I'm still convinced it's not really different:
I'm now about to start my 3rd job. It's always the same. The frontend codebase is complete shit. It's not because some juniors messed up not at all. It's always some highly paid self-proclaimed full-stack developer that didn't really care somehow hacked together most of the codebase.
That person got a rediculous salary considering the actual skill and effort that went into the code, at some point things became difficult, issues started to occur and that person left. If I search for that person I find next to the worst code via gitlens on Linkedin it's somebody that has changed companies at least two times after leaving and works now for a lot of money as tech-lead at some company.
There's never any tests. At the same time the company takes pride in having decent test coverage on the backend. In the end this only results in pushing a lot of business logic to the frontend because it would just take way to long to implement it on the backend.
Most of the time I'm getting told on my first day that the code quality is really high or some bullshit.
It's always a redux app written by people, that just connect everything to the store and never tried to reflect about their use of redux.
Usually it's people, that never even considered or tried not using redux, even if it's just to learn and experiment.
At the same time you could have the most awesome projects on github but people look at your CV, sum up the years and if you invested a lot of time, worked way harder to be better than other developers with the same amount of experience, it's totally irrelevant.
At the same time all companies are just the worst crybabies about not being able to find enough developers.
HR and recruiters are generally happy to invite somebody for an interview, even if that person does not have any code available to the public, as long as that person somehow was in some way employed in the industry for a couple of years. At the same time they wouldn't even notice if you're core contributor for some major open-source product if you do not have the necessary number of years in the industry.
I'm just fed up.
By the way, I got my first real job about two years ago. Now I'm about to start my third position because my last job died because of the corona crisis. I didn't complain for some time because I didn't want to look like I'm just complaining about my own situation. With every new job I made more money, now I'm starting for the first time at a position that is labeled "lead" in the contract.
So I did okay. But I know that lots of talented people that worked hard gave up at some point and even those that made it had to deal with way too much rejection.
At the same time there are so many "senior" people in the industry, that don't care, don't even try to get better, that get a lot of money for nothing.
It's ridiculously hard to get a food in the door if you don't have any experience.
But that's not because juniors are actually useless. It's because the code written by many seniors is so low quality, that you need multiple years of experience just to deal with all the traps.
Furthermore those seniors are so busy trying to put out the fires they are responsible for to actually put time into mentoring juniors.
It's just so fucked up.3 -
Any Unity3D devs out there?
My thoughts: Unity3D is an amazing game engine. It lets you really quickly go from concept to implementation and allows you to prototype very quickly. My concern is that I find it incredibly hard to write good code using it. It's very difficult to write in a test driven way, especially if you put any logic in a MonoBehaviour. It is possible to work around this by using Zenject or another DI framework. You could even use entitas which is an entity component system. But these all have their downsides too. Zenject I find to be quite boilerplatey and not that easy to test either. I also find it really frustrating to be using a really old very of C# (maybe C#4 equivalent but I think it's customised in some way for the engine).
Anyone else struggle to enjoy writing code for Unity3D games?18 -
I have to rewrite a good chunk of logic because it is too hard for any one of 4 people to complete a 5 minute job within 7 days.
I hate users. -
My first CS class is a basic introductory C++ course. Won't even be going into OOP.
So I want to use my own laptop for the course, but I have a Mac. Thought I could use Visual Studio for Mac for the class, but turns out Visual Studio for Mac is really only for Multiplatform development with C#. Ok, then, screw that. Just wasted 20GB and an evening installing that just to uninstall it.
I'm using JetBrain's CLion for now, but apparently we'll be doing some graphics work later this semester so I'm going to need to install Windows via Bootcamp and Visual Studio there... but my SSD is too small...
I currently have Windows/Bootcamp installed on a 1TB external hard disk but that is slow af. My SSD is only 250GB and I've already used half of it for various programs I need (Adobe crap plus Logic crap cuz I make videos and music).
My only option here is to buy a new SSD but only one manufacturer sells those (OWC), and a 1TB SSD is stupid expensive, $700 almost as much as I paid for this laptop used.
So, I guess I'm just kinda deciding right now whether upgrading storage is really worth it...6
