Hi, I am a Javascript apprentice. Can you help me with my project?
- Sure! What do you need?
Oh, it’s very simple, I just want to make a static webpage that shows a clock with the real time.
- Wait, why static? Why not dynamic?
I don’t know, I guess it’ll be easier.
- Well, maybe, but that’s boring, and if that’s boring you are not going to put in time, and if you’re not going to put in time, it’s going to be harder; so it’s better to start with something harder in order to make it easier.
You know that doesn’t make sense right?
- When you learn Javascript you’ll get it.
Okay, so I want to parse this date first to make the clock be universal for all the regions.
- You’re not going to do that by yourself right? You know what they say, don’t repeat yourself!
But it’s just two lines.
- Don’t reinvent the wheel!
Literally, Javascript has a built in library for t...
- One component per file!
I’m lost.
- It happens, and you’ll get lost managing your files as well. You should use Webpack or Browserify for managing your modules.
Doesn’t Javascript include that already?
- Yes, but some people still have previous versions of ECMAScript, so it wouldn’t be compatible.
What’s ECMAScript?
- Javascript
Why is it called ECMAScript then?
- It’s called both ways. Anyways, after you install Webpack to manage your modules, you still need a module and dependency manager, such as bower, or node package manager or yarn.
What does that have to do with my page?
- So you can install AngularJS.
What’s AngularJS?
- A Javascript framework that allows you to do complex stuff easily, such as two way data binding!
Oh, that’s great, so if I modify one sentence on a part of the page, it will automatically refresh the other part of the page which is related to the first one and viceversa?
- Exactly! Except two way data binding is not recommended, since you don’t want child components to edit the parent components of your app.
Then why make two way data binding in the first place?
- It’s backed up by Google. You just don’t get it do you?
I have installed AngularJS now, but it seems I have to redefine something called a... directive?
- AngularJS is old now, you should start using Angular, aka Angular 2.
But it’s the same name... wtf! Only 3 minutes have passed since we started talking, how are they in Angular 2 already?
- You mean 3.
2.
- 3.
4?
- 5.
6?
- Exactly.
Okay, I now know Angular 6.0, and use a component based architecture using only a one way data binding, I have read and started using the Design Patterns already described to solve my problem without reinventing the wheel using libraries such as lodash and D3 for a world map visualization of my clock as well as moment to parse the dates correctly. I also used ECMAScript 6 with Babel to secure backwards compatibility.
- That’s good.
Really?
- Yes, except you didn’t concatenate your html into templates that can be under a super Javascript file which can, then, be concatenated along all your Javascript files and finally be minimized in order to reduce latency. And automate all that process using Gulp while testing every single unit of your code using Jasmine or protractor or just the Angular built in unit tester.
I did.
- But did you use TypeScript?37 -
Every day.
I am a PHP developer.
Yeah, "another PHP is awful" rant... no, not really.
It's just unsuitable for some ambitious projects, just like Ruby and Python are.
First of all, DO NOT EVER use Laravel for large enterprise applications. The same goes for RoR, Django, and other ActiveRecord MVCs.
They are all neat frameworks for writing a todo app, as a better-than-wordpress flexible blogging solution, even as a custom webshop.
Beyond 50k daily users, Active Record becomes hell due to it's lazy fat querying habits. At more than a million users... *depressed sigh*.
PHP is also completely unsuitable for projects beyond 5M lines of code in my opinion. At more than 25M lines... *another depressed sigh*.
You can let your devs read Clean Code and books about architecture patterns, you can teach them about SOLID & DRY, you can write thousands of tests... it doesn't matter.
PHP is scaffolding, it's made of bamboo and rope. It's not brick or concrete. You can build quickly, but it only scales up to a certain point before it breaks in multiple places.
Eventually you run into patterns where even 100% test coverage still doesn't guarantee shit, because the real-life edge cases are just too complex and numerous.
When you're working on a multi-party invoicing system with adapters for various tax codes, or an availability/planning system working across timezones, or systems which implement geographical routefinding coupled to traffic, event & weather prediction...
PHP, Python, Ruby, etc are just missing types.
Every day I run into bugs which could have been prevented if you could use ADTs in a generic way in PHP. PHP7 has pretty good typehints, and they prevent a lot of messy behavior, but they aren't composable. There is no way to tell PHP "this method accepts a Collection of Users", or "this methods returns maybe either an Apple or a Pear, and I want to force the caller to handle both Apple/Pear and null".
Well, you could do that, but it requires a lot of custom classes and trickery, and you have to rewrite the same logic if you want to typehint a "Collection of Departments" instead of "Collection of Users" -- i.e., it's not composable.
Probably the biggest issue is that languages with a (mostly) structural type system (Haskell, Rust, even C#/JVM languages to some degree, etc) are much slower to develop in for the "startup" era of a project, so you grab a weak, quick prototyping language to get started.
Then, when you reach a more grown up phase, you wish you had a better type system at your disposal...28 -
Having PHP as my most useful skill.
I know various other languages, but they're either too exotic for professional use, or my knowledge about them doesn't have the same depth as with PHP.
People joke about how awful PHP is, and it's not entirely true. The incongruous stuff such as confusing parameter ordering can be fixed with libraries. And PHP7 fixed a lot of the ugly stuff. A good dev can certainly write structured, readable, performant PHP code.
But there is a real hard limit. PHP is missing more complex type definitions present in other languages. A weak type system is like building stuff with popsicle sticks and bits of duct tape, it works fast and perfectly fine for small projects, but the lack of strictness is a problem when you have thousands of classes intertwined in all kinds of complex factory, service and repository patterns. And the simple type hints are still newish and fully optional, which means a lot of people don't use them.
So I regret getting stuck in this self reinforcing loop, where I learn more about a very imperfect language through employment, and keep rolling into jobs using that skill because it's what I'm most experienced with.16 -
Them: Root, you take too long to get tickets out. You only have a few simple ones. You really need to rebuild your reputation.
Also them: Hey, could you revisit this ticket? Could you help ____ with this other ticket? Hey Root, how do you do this? Root, someone had a suggestion on one of your tickets; could you implement that by EoD? Hey Root, i didn't read your ticket notes; how do you test it? Hey, could you revisit this ticket for the fourth time and remove some whitespace? Hey Root, someone has non-blocking code review comments you need to address before we can release the ticket. Hey Root, we want to expand that ticket scope by 5-6 times; still labeled a trivial feature though.
Also them: Super easy ticket for you. Make sure you talk with teams A, B, C, D, E and get their input on the ticket, talk with ____ and ____ and ____ about it, find a solution that makes them all happy and solves the problem too, then be sure to demo it with everyone afterward. Super easy; shouldn't take you more than a couple days. Oh, and half of them are on vacation.
Also them: Hey, that high-priority ticket you finished months ago that we ignored? Yeah, you need to rewrite it by tomorrow. Also, you need to demo it with our guy in India, who's also on vacation. Yes, tomorrow is the last day. (The next day:) You rewrote it, but weren't able to schedule the demo? Now you've missed the release! It's even later! This reflects very poorly on you.
Also them: Perfect is the enemy of good; be more like the seniors who release partially-broken code quickly.
Also them: Here's an non-trivial extreme edgecase you might not have covered. Oh, it would have taken too much time and that's why you didn't do it? Jeez, how can you release such incomplete code?
Also them: Yeah, that ticket sat in code review for five months because we didn't know it was high-priority, despite you telling us. It's still kinda your fault, though.
Also them: You need to analyze traffic data to find patterns and figure out why this problem is happening. I know you pushed the fix for it 8 months ago, and I said it was really solid, but the code is too complex so I won't release it. Yeah I know it's just a debounce with status polling and retrying. Too complex for me to understand. Figure out what the problem is, see if another company has this same problem, and how they fixed it.
-------------
Yep. I'm so terrible for not getting these tickets out, like wow. Worst dev ever. Much shame.

I just love refactoring :) that feeling when an agonic 50loc method with ifs, loops, streams, other shit shrinks down to 3 lines with descriptive and SRP-compliant method calls.. When you can actually read code as a nicely written story. When there are no rubbish comments, cryptic variables and no overly complex if-else skyscrapers jamming all the logic in one conditional chain. When all the abstractions are designed so nicely and design patterns applied so perfectly that extending either of the components is as easy as a walk in a park.
When everything is nice and neat. Only then can I sleep well and enjoy the autumn :)
just some random thoughts after today's coding session :)5 -
Worst collaboration experience story?
I was not directly involved, it was a Delphi -> C# conversion of our customer returns application.
The dev manager was out to prove waterfall was the only development methodology that could make convert the monolith app to a lean, multi-tier, enterprise-worthy application.
Starting out with a team of 7 (3 devs, 2 dbas, team mgr, and the dev department mgr), they spent around 3 months designing, meetings, and more meetings. Armed with 50+ page specification Word document (not counting the countless Visio workflow diagrams and Microsoft Project timeline/ghantt charts), the team was ready to start coding.
The database design, workflow, and UI design (using Visio), was well done/thought out, but problems started on day one.
- Team mgr and Dev mgr split up the 3 devs, 1 dev wrote the database access library tier, 1 wrote the service tier, the other dev wrote the UI (I'll add this was the dev's first experience with WPF).
- Per the specification, all the layers wouldn't be integrated until all of them met the standards (unit tested, free from errors from VS's code analyzer, etc)
- By the time the devs where ready to code, the DBAs were already tasked with other projects, so the Returns app was prioritized to "when we get around to it"
Fast forward 6 months later, all the devs were 'done' coding, having very little/no communication with one another, then the integration. The service and database layers assumed different design patterns and different database relationships and the UI layer required functionality neither layers anticipated (ex. multi-users and the service maintaining some sort of state between them).
Those issues took about a month to work out, then the app began beta testing with real end users. App didn't make it 10 minutes before users gave up. Numerous UI logic errors, runtime errors, and overall app stability. Because the UI was so bad, the dev mgr brought in one of the web developers (she was pretty good at UI design). You might guess how useful someone is being dropped in on complex project , months after-the-fact and being told "Fix it!".
Couple of months of UI re-design and many other changes, the app was ready for beta testing.
In the mean time, the company hired a new customer service manager. When he saw the application, he rejected the app because he re-designed the entire returns process to be more efficient. The application UI was written to the exact step-by-step old returns process with little/no deviation.
With a tremendous amount of push-back (TL;DR), the dev mgr promised to change the app, but only after it was deployed into production (using "we can fix it later" excuse).
Still plagued with numerous bugs, the app was finally deployed. In attempts to save face, there was a company-wide party to celebrate the 'death' of the "old Delphi returns app" and the birth of the new. Cake, drinks, certificates of achievements for the devs, etc.
By the end of the project, the devs hated each other. Finger pointing, petty squabbles, out-right "FU!"s across the cube walls, etc. All the team members were re-assigned to other teams to separate them, leaving a single new hire to fix all the issues.5 -
I am in love with regex (re in py)!
It is so damn cool!
Unfortunately, Python's find is faster.
But regex is so much better when it comes to complex patterns you would not be able to find with the regular (do you see the pun here? ;)) python's string object find method.4 -
I’m so sick and tired of the cattle-minded people in the software world. I love coding and improving myself; I've got over 18 years of experience. I enjoy what I do, and I like being good at it. I know my way around a variety of different technologies, and I could easily outperform most engineers with similar experience. If I don’t know something, I get excited to learn and I ask questions. I don’t enjoy standing in the spotlight about what I know; I prefer supporting, helping, solving problems, improving solutions, and simplifying everything.
From my experience, the best solution is the simplest, shortest, fastest, and leanest one. But unfortunately, there are people in the workplace who think the opposite of me and blindly follow this so-called prophet named Uncle Bob, zealously writing all his SOLID principles and dogmatic code, turning their work environments into a toxic mess. I’m so done with it. You have no idea how harmful a person can be when they cling to the teachings of a guy like Uncle Bob—someone who probably hasn't even written the "s" in software himself and is just trying to sell his book. In almost every job or team I join, there’s one of these people who drags junior developers into writing dogmatic code by chanting about SOLID principles, Uncle Bob, and object-oriented programming.
Software engineering isn’t something you can learn from a book written by people like Uncle Bob, who haven’t coded a decent product in a real development process. Experience is something entirely different, and from my experience, everything taken to extremes turns out badly. Wherever I see an Uncle Bob disciple, the work inevitably slides into the extremes. For someone writing in C and C++, it’s disheartening to hear about object-oriented programming, SOLID principles, and agile nonsense. I’m tired of seeing people cluttering their code with interfaces for every little thing, over-engineering patterns, and stuffing every piece of code with interfaces to make it “testable.” They run around claiming they’re writing SOLID code, doing TDD, following “best practices,” yet they can't solve any real problems or algorithms. They take a week-long task and drag it out to six, making simple things complex and distancing themselves from real solutions. I’m sick of these types.
If you’re a junior developer, please ignore the fools trying to lead you down this path, and don’t become dogmatic about what you learn, especially if you’re writing C++.
I’ve never seen any real engineer who takes this SOLID, object-oriented nonsense seriously. Believe me, once you reach a certain threshold, you won’t hear these words anymore. Software isn’t just about that. Object-oriented programming, especially if you’re not writing Java or C#, and especially if you’re working in C++ (thankfully, C doesn’t even have it), is something you should definitely steer clear of. Robert C. Martin, aka Uncle Bob—if only you had written your book with a focus on Java or C#. These dogmatic code writers with 7-8 years of experience crying at the sight of free functions in C++ really give me a headache. Because of you, these people exist, and I don’t have the energy to deal with this nonsense at my age.rant agile uncle bob object oriented solid c dogmatic code oop solid principles c++ tdd robert.c martin7 -

Need some opinions. Joined a new company recently (yippee!!!). Just getting to grips with everything at the minute. I'm working on mobile and I will be setting up a new team to take over a project from a remote team. Looking at their iOS and Android code and they are using RxSwift and RxJava in them.
Don't know a whole lot about the Android space yet, but on iOS I did look into Reactive Cocoa at one point, and really didn't like it. Does anyone here use Rx, or have an opinion about them, good or bad? I can learn them myself, i'm not looking for help with that, i'm more interested in opinions on the tools themselves.
My initial view (with a lack of experience in the area):
- I'm not a huge fan of frameworks like this that attempt to change the entire flow or structure of a language / platform. I like using third party libraries, but to me, its excessive to include something like this rather than just learning the in's / out's of the platform. I think the reactive approach has its use cases and i'm not knocking the it all together. I just feel like this is a little bit of forcing a square peg into a round hole. Swift wasn't designed to work like that and a big layer will need to be added in, in order to change it. I would want to see tremendous gains in order to justify it, and frankly I don't see it compared to other approaches.
- I do like the MVVM approach included with it, but i've easily managed to do similar with a handful of protocols that didn't require a new architecture and approach.
- Not sure if this is an RxSwift thing, or just how its implemented here. But all ViewControllers need to be created by using a coordinator first. This really bugs me because it means changing everything again. When I first opened this app, login was being skipped, trying to add it back in by selecting the default storyboard gave me "unwrapping a nil optional" errors, which took a little while to figure out what was going on. This, to me, again is changing too much in the platform that even the basic launching of a screen now needs to be changed. It will be confusing while trying to build a new team who may or may not know the tech.
- I'm concerned about hiring new staff and having to make sure that they know this, can learn it or are even happy to do so.
- I'm concerned about having a decrease in the community size to debug issues. Had horrible experiences with this in the past with hybrid tech.
- I'm concerned with bugs being introduced or patterns being changed in the tool itself. Because it changes and touches everything, it will be a nightmare to rip it out or use something else and we'll be stuck with the issue. This seems to have happened with ReactiveCocoa where they made a change to their approach that seems to have caused a divide in the community, with people splitting off into other tech.
- In this app we have base Swift, with RxSwift and RxCocoa on top, with AlamoFire on top of that, with Moya on that and RxMoya on top again. This to me is too much when only looking at basic screens and networking. I would be concerned that moving to something more complex that we might end up with a tonne of dependencies.
- There seems to be issues with the server (nothing to do with RxSwift) but the errors seem to be getting caught by RxSwift and turned into very vague and difficult to debug console logs. "RxSwift.RxError error 4" is not great. Now again this could be a "way its being used" issue as oppose to an issue with RxSwift itself. But again were back to a big middle layer sitting between me and what I want to access. I've already had issues with login seeming to have 2 states, success or wrong password, meaning its not telling the user whats actually wrong. Now i'm not sure if this is bad dev or bad tools, but I get a sense RxSwift is contributing to it in some fashion, at least in this specific use of it.
I'll leave it there for now, any opinions or advice would be appreciated.question functional programming reactivex java library reactive ios functional swift android rxswift rxjava18 -
what kind of dumb fuck you have to be to get the react js dev job in company that has agile processes if you hate the JS all the way along with refusing to invest your time to learn about shit you are supposed to do and let's add total lack of understanding how things work, specifically giving zero fucks about agile and mocking it on every occasion and asking stupid questions that are answered in first 5 minutes of reading any blog post about intro to agile processes? Is it to annoy the shit out of others?
On top of that trying to reinvent the wheels for every friggin task with some totally unrelated tech or stack that is not used in the company you work for?
and solution is always half-assed and I always find flaw in it by just looking at it as there are tons of battle-tested solutions or patterns that are better by 100 miles regarding ease of use, security and optimization.
classic php/mysql backend issues - "ooh, the java has garbage collector" - i don't give a fuck about java at this company, give me friggin php solution - 'ooh, that issue in python/haskel/C#/LUA/basically any other prog language is resolved totally different and it looks better!' - well it seems that he knows everything besides php!
Yeah we will change all the fucking tech we use in this huge ass app because your inability to learn to focus on the friggin problem in the friggin language you got the job for.
Guy works with react, asked about thoughts on react - 'i hope it cease to exists along with whole JS ecosystem as soon as possible, because JS is weird'. Great, why did you fucking applied for the job in the first place if it pushes all of your wrong buttons!
Fucking rockstar/ninja developers! (and I don't mean on actual 'rockstar' language devs).
Also constantly talks about game development and we are developing web-related suite of apps, so why the fuck did you even applied? why?
I just hate that attitude of mocking everything and everyone along with the 'god complex' without really contributing with any constructive feedback combined with half-assed doing something that someone before him already mastered and on top of that pretending that is on the same level, but mainly acting as at least 2 levels above, alas in reality just produces bolognese that everybody has to clean up later.
When someone gives constructive feedback with lenghty argument why and how that solution is wrong on so many levels, pulls the 'well, i'm still learning that' card.
If I as code monkey can learn something in 2 friggin days including good practices and most of crazy intricacies about that new thing, you as a programmer god should be able to learn it in 2 fucking hours!
Fucking arrogant pricks!8 -
Developers who think complex code is good.
"Oh, lookie here, I can swizzle methods and inject dependencies in the runtime!"
"Although we have no valid use case, let's use dependency injection and follow the commandory stateor patterns because I watched a video."
Just because you learn something new that looks cool does not make it practical, you tosser.1 -
Got a new job on a big brand bank in the financial district in NYC, went through multiple code interviews, 2 hours of in person interviews asking me about architectures, design patterns, solutions to imaginary complex problems(which I enjoyed thinking about), finally got accepted, background checks needed before starting (previous job check, credit, drugs, etc..) so I waited 2 months, 1st day at work, the building is huge and cool, biggest spaces I've ever seen, amazingly insane large monitors and people working on a great variety of new technologies.
I was assigned to a corner far away from the open spaces, trying to understand a project that I will maintain who works with java 5, struts and jsp(for fucks sake, JSP!!!)
Why life laughs on my face? why?4 -
In PHP, constants can only be of simple data types like strings or floats.
You can't make a database connection a constant because it's not a simple data type.
That makes the only way of accessing complex "constants" within functions using the keyword global... which is not encouraged and forces you to make the database connection global (that may not be convenient in some software patterns).
The last option is passing the database connection as a parameter (either to the function or to the constructor of the instance whose methods will use the connection)... which would be good if I didn't want to go full OO. Because it's a pain to do so.
So all in all, constants are not well supported by PHP.
Come on, constants...12 -
I absolutely hate software to the point where I started converting from sysadmin to becoming more like a dev. That way I could just write my own implementations at will. Easier said than done, that's for sure. And it goes both ways.
I think that in order to be a good dev, you need these skills the most:
- Problem solving skills
- Creativity, you're making stuff
- Logical reasoning
- Connecting the dots
- Reading complex documentation
- Breaking down said documentation
- A strong desire to create order and patterns
- ...
If you don't have the above, you may still be able to become a dev.. but it would be harder for sure, and in some cases acceptance will be lower (seriously, learn to Google!)
One thing I don't think you need in development is mathematics. Sure there's a correlation between it and logic reasoning, but you're not solving big mathematical monsters here. At most you'd probably be dealing with arrays and loops (well.. program logic).
Also, written and spoken English! The language of the internet must be known. If it's not your first language, learn it. All the good (and crucial) documentation out there is in English after all.
One final thing would be security in my opinion, since you're releasing your application to the internet and may even run certain services, and deal with a lot of user data. Making those things secure takes some effort and knowledge on security, but it's so worth it. At the most basic level, it requires a certain mindset: "how would I break this thing I just made?"4 -
A software had been developed over a decade ago. With critical design problems, it grew slower and buggier over time.
As a simple change in any area could create new bugs in other parts, gradually the developers team decided not to change the software any more, instead for fixing bugs or adding features, every time a new software should be developed which monitors the main software, and tries to change its output from outside! For example, look into the outputs and inputs, and whenever there's this number in the output considering this sequence of inputs, change the output to this instead.
As all the patchwork is done from outside, auxiliary software are very huge. They have to have parts to save and monitor inputs and outputs and algorithms to communicate with the main software and its clients.
As this architecture becomes more and more complex, company negotiates with users to convince them to change their habits a bit. Like instead of receiving an email with latest notifications, download a csv every day from a url which gives them their notifications! Because it is then easier for developers to build.
As the project grows, company hires more and more developers to work on this gigantic project. Suddenly, some day, there comes a young talented developer who realizes if the company develops the software from scratch, it could become 100 times smaller as there will be no patchwork, no monitoring of the outputs and inputs and no reverse engineering to figure out why the system behaves like this to change its behavior and finally, no arrangement with users to download weird csv files as there will be a fresh new code base using latest design patterns and a modern UI.
Managers but, are unaware of technical jargon and have no time to listen to a curious kid! They look into the list of payrolls and say, replacing something we spent millions of man hours to build, is IMPOSSIBLE! Get back to your work or find another job!
Most people decide to remain silence and therefore the madness continues with no resistance. That's why when you buy a ticket from a public transport system you see long delays and various unexpected behavior. That's why when you are waiting to receive an SMS from your bank you might end up requesting a letter by post instead!
Yet there are some rebel developers who stand and fight! They finally get expelled from the famous powerful system down to the streets. They are free to open their startups and develop their dream system. They do. But government (as the only client most of the time), would look into the budget spending and says: How can we replace an annually billion dollar project without a toy built by a bunch of kids? And the madness continues.... Boeings crash, space programs stagnate and banks take forever to process risks and react. This is our world.3 -
I can be manipulated. Yes, I’m now more resilient to manipulation than ever because I’m autistically good at recognising patterns, yet I’m not perfect.
For a manipulator, there is just one problem — now and then, my disorder obliterates my entire worldview, together with the foreign manipulative framework, so I can start with a blank slate. It protects me. Yes, this protection is akin to our body’s “we’ll boil all the germs in our own blood” tactic that instead of defining winners and losers only leave survivors, yet the force is unstoppable. You cannot secure the land that is hit by a tornado every three months.
That inner Nemesis is so strong that it even defeated a complex, almost fractal-like manipulation of my own mother that I lived in since birth, leaving her with a wound that will never heal. Wannabe manipulator exes didn’t even stand a chance. I don’t care if that force destroys me or not, as during that time, there is no “me”.
About my mom, long story short, she told me “I want to stop treating my cancer to die as soon as possible just to not see you anymore” after my coming-out. Full story is here:

I read: "Don't change your implementation to do tests"
Then I read: "If it's too hard to test, your implementation is too complex"
Then we can get into test terminology itself, which is its own mess:

sheesh, if you thought the whole javascript / framework / web ecosystem always feels immature and behind other areas of software, i'm about to argue that testing patterns are even further behind8 -
7 days in, still can't get anything more than the infinitely seen tutorial GET / request working on a lambda function.
Oh, you've got something more complex, god forbid a POST handler? well, prepare yourself for days of suffering.
how far can you really go from standard software patterns?
Giving it about 20 more minutes and i'm going full self-managed, I don't have time for this shit

I see bad data and thought to myself, "I'll be able to fix this with a simple regex." A month later, I'm still finding new data patterns. Never give users the ability to store all of their data in a huge textarea box where they can make stuff up.2
-
Today I deeply understood/learned that if anything complex has to be built, tested and maintained by a single person the most important factor to don't go crazy is the concepts of "separation of concern".
Even though it makes the development slower (*) and quite some times boring it gives back in almost absence of uncertainty and because of repetitive patterns also ease on going back to work on a new/old part/feature.
(*) Because of planning and organisation of the code flows and layers flows, but also compartmentalization of actions (a bad example would be the mix of validation code with CRUD code)
How do you experience the separation of concern? (If you have ever had the chance)
Ps: still earning ~1400€/m, am I worth more? 🤔4 -
Ever since I started learning about React with Typescript my respect for design patterns that restrict how state can change has grown massively. On the web, nothing happens when you say it should happen; everything always takes a while to execute and there is always a transactional period between validating an action with client-side state and receiving the result from the server, and if you want to account for that everything becomes infinitely more complex and you eventually end up with mutexes.5

Sydochen has posted a rant where he is nt really sure why people hate Java, and I decided to publicly post my explanation of this phenomenon, please, from my point of view.
So there is this quite large domain, on which one or two academical studies are built, such as business informatics and applied system engineering which I find extremely interesting and fun, that is called, ironically, SAD. And then there are videos on youtube, by programmers who just can't settle the fuck down. Those videos I am talking about are rants about OOP in general, which, as we all know, is a huge part of studies in the aforementioned domain. What these people are even talking about?
Absolutely obvious, there is no sense in making a software in a linear pattern. Since Bikelsoft has conveniently patched consumers up with GUI based software, the core concept of which is EDP (event driven programming or alternatively, at least OS events queue-ing), the completely functional, linear approach in such environment does not make much sense in terms of the maintainability of the software. Uhm, raise your hand if you ever tried to linearly build a complex GUI system in a single function call on GTK, which does allow you to disregard any responsibility separation pattern of SAD, such as long loved MVC...
Additionally, OOP is mandatory in business because it does allow us to mount abstraction levels and encapsulate actual dataflow behind them, which, of course, lowers the costs of the development.
What happy programmers are talking about usually is the complexity of the task of doing the OOP right in the sense of an overflow of straight composition classes (that do nothing but forward data from lower to upper abstraction levels and vice versa) and the situation of responsibility chain break (this is when a class from lower level directly!! notifies a class of a higher level about something ignoring the fact that there is a chain of other classes between them). And that's it. These guys also do vouch for functional programming, and it's a completely different argument, and there is no reason not to do it in algorithmical, implementational part of the project, of course, but yeah...
So where does Java kick in you think?
Well, guess what language popularized programming in general and OOP in particular. Java is doing a lot of things in a modern way. Of course, if it's 1995 outside *lenny face*. Yeah, fuck AOT, fuck memory management responsibility, all to the maximum towards solving the real applicative tasks.
Have you ever tried to learn to apply Text Watchers in Android with Java? Then you know about inline overloading and inline abstract class implementation. This is not right. This reduces readability and reusability.
Have you ever used Volley on Android? Newbies to Android programming surely should have. Quite verbose boilerplate in google docs, huh?
Have you seen intents? The Android API is, little said, messy with all the support libs and Context class ancestors. Remember how many times the language has helped you to properly orient in all of this hierarchy, when overloading method declaration requires you to use 2 lines instead of 1. Too verbose, too hesitant, distracting - that's what the lang and the api is. Fucking toString() is hilarious. Reference comparison is unintuitive. Obviously poor practices are not banned. Ancient tools. Import hell. Slow evolution.
C# has ripped Java off like an utter cunt, yet it's a piece of cake to maintain a solid patternization and structure, and keep your code clean and readable. Yet, Cs6 already was okay featuring optionally nullable fields and safe optional dereferencing, while we get finally get lambda expressions in J8, in 20-fucking-14.
Java did good back then, but when we joke about dumb indian developers, they are coding it in Java. So yeah.
To sum up, it's easy to make code unreadable with Java, and Java is a tool with which developers usually disregard the patterns of SAD. -
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 -
Just Started learning unsupervised learning algorithms, and i write this: Unsupervised Learning is an AI procedure, where you don’t have to set the standard. Preferably, you have to allow the model to take a chance at its own to see data.
Unsupervised Learning calculations allow you to make increasingly complex planning projects contrasted with managed learning. Albeit, Unsupervised Learning can be progressively whimsical contrasted and other specific learning plans.
Unsupervised machine learning algorithm induces patterns from a dataset without relating to known or checked results. Not at all like supervised machine learning, Unsupervised Machine Learning approaches can’t be legitimately used to loss or an order issue since you have no proof of what the conditions for the yield data may be, making it difficult for you to prepare the estimate how you usually would. Unsupervised Learning can preferably be used to get the essential structure of the data.
