Search - "functional"

I’m surrounded by idiots.
I’m continually reminded of that fact, but today I found something that really drives that point home.
Gather ‘round, everybody, it’s story time!
While working on a slow query ticket, I perused the code, finding several causes, and decided to run git blame on the files to see what dummy authored the mental diarrhea currently befouling my screen. As it turns out, the entire feature was written by mister legendary Apple golden boy “Finder’s Keeper” dev himself.
To give you the full scope of this mess, let me start at the frontend and work my way backward.
He wrote a javascript method that tracks whatever row was/is under the mouse in a table and dynamically removes/adds a “.row_selected” class on it. At least the js uses events (jQuery…) instead of a `setTimeout()` so it could be worse. But still, has he never heard of :hover? The function literally does nothing else, and the `selectedRow` var he stores the element reference in isn’t used elsewhere.
This function allows the user to better see the rows in the API Calls table, for which there is a also search feature — the very thing I’m tasked with fixing.
It’s worth noting that above the search feature are two inputs for a date range, with some helpful links like “last week” and “last month” … and “All”. It’s also worth noting that this table is for displaying search results of all the API requests and their responses for a given merchant… this table is enormous.
This search field for this table queries the backend on every character the user types. There’s no debouncing, no submit event, etc., so it triggers on every keystroke. The actual request runs through a layer of abstraction to parse out and log the user-entered date range, figure out where the request came from, and to map out some column names or add additional ones. It also does some hard to follow (and amazingly not injectable) orm condition building. It’s a mess of functional ugly.
The important columns in the table this query ultimately searches are not indexed, despite it only looking for “create_order” records — the largest of twenty-some types in the table. It also uses partial text matching (again: on. every. single. keystroke.) across two varchar(255)s that only ever hold <16 chars — and of which users only ever care about one at a time. After all of this, it filters the results based on some uncommented regexes, and worst of all: instead of fetching only one page’s worth of results like you’d expect, it fetches all of them at once and then discards what isn’t included by the paginator. So not only is this a guaranteed full table scan with partial text matching for every query (over millions to hundreds of millions of records), it’s that same full table scan for every single keystroke while the user types, and all but 25 records (user-selectable) get discarded — and then requeried when the user looks at the next page of results.
What the bloody fucking hell? I’d swear this idiot is an intern, but his code does (amazingly) actually work.
No wonder this search field nearly crashed one of the servers when someone actually tried using it.
Asdfajsdfk.rant fucking moron even when taking down the server hey bob pass me all the paperclips mysql murder terrible code slow query idiot can do no wrong but he’s the golden boy idiots repeatedly murdered mysql in the face21 -
i was asked to start a new project, and another dev was brought onto the team shortly after. as soon as he joined, straight away he started an entirely new project and worked on it through the whole weekend, then came back on monday and just sort of pasted his files into/over the code i had already started and was working on, with no regard for folder structure or naming conventions or anything. his work was even split between 2 almost identically named namespaces (both of which were completely different to the existing project namespace) and his shit broke everything i did in the first place. the cherry on top is that none of his work was even functional, it was purely dummy/mockup web pages that weren't linked to any sort of backend.
when i asked him wtf he thought he was doing, he kept saying "i didnt touch your code" and refused to acknowledge that pasting a project over a different project can break stuff, then said it "wasn't his fault that i'm slow and not keeping up". and just kept saying vague bullshit about how i have to do it his way because he "has more experience"
he had no idea what my previous experience was, he had never asked and i had never told him, he just decided that he had more experience than me.
i dug through the shit and found out that he didn't just break my work, he had actually purposely deleted it when he realised it was getting in the way of his spaghetti. i showed him the commit and confronted him with it and all the cunt said was "well the good news is, you know the fix" and kept trying to dismiss me in the most disrespectful ways he could think of. i eventually snapped at him (long overdue at this point) and told him that any experienced developer would not commit code that didn't even fucking compile, especially when they're the one who broke it, and that he needs to grow up. of course he then complained that i was being unprofessional.
our manager decided we should go with fuckfaces """code""" without even looking at the work either of us had done, purely because fuckface is older than me and that's how the world works.
in the end i just told my manager that i refuse to work with the guy and he could either take him or me off the project (guess who he picked) or i quit.
after a few months of the guy failing to deliver any of even the basic functionality that was asked for, the entire project got scrapped, and the dude just quit once everyone realised he was literally just larping as an experienced dev but couldn't accomplish simple tasks.
i never received an apology from anybody involved.5 -
How to profesionally say: you fucking illiterate and incompetent piece of shit, I am tired of spoonfeeding you because you dont use your fucking brain. I am fucking tired of explaining same concept over and over again for the past 2-3 months. Open fucking google for once and lookup latest practices, and learn what functional programming is and learn how to use operators instead of fucking inventing wheel again and again with your 100 lines boilerplate of code functions. Open your fucking mind for once and lookup stuff for yourself, instead of asking me to explain everything for the 100th time you lazy fuck. Oh and stop asking me "to be nice", this is gaslightling. I am being professional and I am the only person in this company who actually tolerates u on some level, others are just avoiding you you useless piece of shit. If I need to explain something for 5th time and I make you feel bad, it means you should feel bad. So maybe grow some balls and start putting in some effort, instead of playing the victim when you are the supposed 6 year senior and I am the 3 year junior, who has to do your fucking job half of the time. You are incapable of even using the standard architecture, what you use is fucking 6-7 years old. Fucking code monkey with broken english who doesnt understand what hes doing. You dont like my methods? I dare you to schedule an appointment between me and manager or your useless techlead, but I know you wont do that because I know you are afraid of everyone finding out how incompetent you are. You low fruit hanging task licking incompetent shit.1

I manage a team of engineers.
Toxic Culture Post #2:
Manager: Everybody on your team needs their own swimlane in Jira. Each person's work should be their own lane. When I have a ticket for <Project A> I want to make sure that <Bob> always gets it, all tickets for <Project B> must go to <James>. You'll need to figure out which team member will handle <New Project C> and create their personal swim lane.
Me: That's not really how SCRUM works. Actually, that's not how teamwork works. You're creating silos and we all need to learn how to do these tasks. We're a cross-functional team, and each team member brings their own unique talents to the whole process.
Manager: So you'll create the swimlanes?
Me: No
Manager (to Bob): You'll be devoted to <Project A> from now own. It's the only work I expect you to do. All work for that project will be yours.
Likewise, my manager also reached out to each team member and assigned them specific tasks, furthering the silos.6 -
start teaching people how and why to delete code instead of teaching them only how to write code
compare functional and object oriented languages as well as high level and low level languages and explain what are advantages of using certain language without going into the syntax
let people do mistakes and don’t punish people for making them but let them explain what happened, if they know what was the cause of mistake it is worth ten times than doing things correctly
mix teams per period of time instead of per project
make showcases how to modify ugly code to pretty one and what are the steps and what patterns people should look after
teach by not showing old stuff but showing where old stuff exists in modern things and why it’s important there and what’s the purpose of doing things certain way instead of flat theory based on ancient examples1 -
I'm finally realising my long time dream and making a programming language. It's a functional language resemblent in both appearance and usage to lambda calculus. I'll mostly be making plans down to the finest details until the end of summer, at which point if I can gauge the challenge I can hopefully submit this as a graduate project.
This is the first in a series of articles documenting my progress:

I AM TIRED
warning: this rant is going to be full of negativity , CAPS, and cursing.
People always think and they always write that programming is an analytical profession. IF YOU CANNOT THINK IN AN ANALYTICAL WAY THIS JOB IS NOT FOR YOU! But the reality could not be farther from the truth.
A LOT of people in this field whether they're technical people or otherwise, just lack any kind of reasoning or "ANALYTICAL" thinking skills. If anything, a lot of of them are delusional and/or they just care about looking COOL. "Because programming is like getting paid to solve puzzles" *insert stupid retarded laugh here*.
A lot of devs out there just read a book or two and read a Medium article by another wannabe, now think they're hot shit. They know what they're doing. They're the gods of "clean" and "modular" design and all companies should be in AWE of their skills paralleled only by those of deities!
Everyone out there and their Neanderthal ancestor from start-up founders to developers think they're the next Google/Amazon/Facebook/*insert fancy shitty tech company*.
Founder? THEY WANT TO MOVE FAST AND GET TO MARKET FAST WITH STUPID DEADLINES! even if it's not necessary. Why? BECAUSE YOU INFERIOR DEVELOPER HAVE NOT READ THE STUPID HOT PILE OF GARBAGE I READ ONLINE BY THE POEPLE I BLINDLY COPY! "IF YOU'RE NOT EMBARRASSED BY THE FIRST VERSION OF YOU APP, YOU DID SOMETHING WRONG" - someone at Amazon.
Well you delusional brainless piece of stupidity, YOU ARE NOT AMAZON. THE FIRST VERSION THAT THIS AMAZON FOUNDER IS EMBARRASSED ABOUT IS WHAT YOU JERK OFF TO AT NIGHT! IT IS WHAT YOU DREAM ABOUT HAVING!
And oh let's not forget the tech stacks that make absolutely no fucking sense and are just a pile of glue and abstraction levels on top of abstraction levels that are being used everywhere. Why? BECAUSE GOOGLE DOES IT THAT WAY DUH!! And when Google (or any other fancy shit company) changes it, the old shitty tech stack that by some miracle you got to work and everyone is writing in, is now all of a sudden OBSOLETE! IT IS OLD. NO ONE IS WRITING SHIT IN THAT ANYMORE!
And oh my god do I get a PTSD every time I hear a stupid fucker saying shit like "clean architecture" "clean shit" "best practice". Because I have yet to see someone whose sentences HAVE TO HAVE one of these words in them, that actually writes anything decent. They say this shit because of some garbage article they read online and in reality when you look at their code it is hot heap of horseshit after eating something rancid. NOTHING IS CLEAN ABOUT IT. NOTHING IS DONE RIGHT. AND OH GOD IF THAT PERSON WAS YOUR TECH MANAGER AND YOU HAVE TO LISTEN TO THEM RUNNING THEIR SHITHOLE ABOUT HOW YOUR SIMPLE CODE IS "NOT CLEAN". And when you think that there might be a valid reason to why they're doing things that way, you get an answer of someone in an interview who's been asked about something they don't know, but they're trying to BS their way to sounding smart and knowledgable. 0 logic 0 reason 0 brain.
Let me give you a couple of examples from my unfortunate encounters in the land of the delusional.
I was working at this start up which is fairly successful and there was this guy responsible for developing the front-end of their website using ReactJS and they're using Redux (WHOSE SOLE PURPOSE IS TO ELIMINATE PASSING ATTRIBUTES FOR THE PURPOSE OF PASSING THEM DOWN THE COMPONENT HIERARCHY AGIAN). This guy kept ranting about their quality and their shit every single time we had a conversation about the code while I was getting to know everything. Also keep in mind he was the one who decided to use Redux. Low and behold there was this component which has THIRTY MOTHERFUCKING SEVEN PROPERTIES WHOSE SOLE PURPOSE IS BE PASSED DOWN AGAIN LIKE 3 TO 4 TIMES!.
This stupid shit kept telling me to write code in a "functional" style. AND ALL HE KNOWS ABOUT FUNCTIONAL PROGRAMMING IS USING MAP, FILTER, REDUCE! And says shit like "WE DONT NEED UNIT TESTS BECAUSE FUNCTIONAL PROGRAMMING HAS NO ERRORS!" Later on I found that he read a book about functional programming in JS and now he fucking thinks he knows what functional programming is! Oh I forgot to mention that the body of his "maps" is like 70 fucking lines of code!
Another fin-tech company I worked at had a quote from Machiavelli's The Prince on EACH FUCKING DESK:
"There is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things."
MOTHERFUCKER! NEW ORDER OF THINGS? THERE 10 OTHER COMPANIES DOING THE SAME SHIT ALREADY!
And the one that got on my nerves as a space lover. Is a quote from Kennedy's speech about going to the moon in the 60s "We choose to go to the moon and do the hard things ..."
YOU FUCKING DELUSIONAL CUNT! YOU THINK BUILDING YOUR SHITTY COPY PASTED START UP IS COMPARABLE TO GOING TO THE MOON IN THE 60S?
I am just tired of all those fuckers.13 -

When I was in college OOP was emerging. A lot of the professors were against teaching it as the core. Some younger professors were adamant about it, and also Java fanatics. So after the bell rang, they'd sometimes teach people that wanted to learn it. I stayed after and the professor said that object oriented programming treated things like reality.
My first thought to this was hold up, modeling reality is hard and complicated, why would you want to add that to your programming that's utter madness.
Then he started with a ball example and how some balls in reality are blue, and they can have a bounce action we can express with a method.
My first thought was that this seems a very niche example. It has very little to do with any problems I have yet solved and I felt thinking about it this way would complicate my programs rather than make them simpler.
I looked around the at remnants of my classmates and saw several sitting forward, their eyes lit up and I felt like I was in a cult meeting where the head is trying to make everyone enamored of their personality. Except he wasn't selling himself, he was selling an idea.
I patiently waited it out, wanting there to be something of value in the after the bell lesson. Something I could use to better my own programming ability. It never came.
This same professor would tell us all to read and buy gang of four it would change our lives. It was an expensive hard cover book with a ribbon attached for a bookmark. It was made to look important. I didn't have much money in college but I gave it a shot I bought the book. I remember wrinkling my nose often, reading at it. Feeling like I was still being sold something. But where was the proof. It was all an argument from authority and I didn't think the argument was very good.
I left college thinking the whole thing was silly and would surely go away with time. And then it grew, and grew. It started to be impossible to avoid it. So I'd just use it when I had to and that became more and more often.
I began to doubt myself. Perhaps I was wrong, surely all these people using and loving this paradigm could not be wrong. I took on a 3 year project to dive deep into OOP later in my career. I was already intimately aware of OOP having to have done so much of it. But I caught up on all the latest ideas and practiced them for a the first year. I thought if OOP is so good I should be able to be more productive in years 2 and 3.
It was the most miserable I had ever been as a programmer. Everything took forever to do. There was boilerplate code everywhere. You didn't so much solve problems as stuff abstract ideas that had nothing to do with the problem everywhere and THEN code the actual part of the code that does a task. Even though I was working with an interpreted language they had added a need to compile, for dependency injection. What's next taking the benefit of dynamic typing and forcing typing into it? Oh I see they managed to do that too. At this point why not just use C or C++. It's going to do everything you wanted if you add compiling and typing and do it way faster at run time.
I talked to the client extensively about everything. We both agreed the project was untenable. We moved everything over another 3 years. His business is doing better than ever before now by several metrics. And I can be productive again. My self doubt was over. OOP is a complicated mess that drags down the software industry, little better than snake oil and full of empty promises. Unfortunately it is all some people know.
Now there is a functional movement, a data oriented movement, and things are looking a little brighter. However, no one seems to care for procedural. Functional and procedural are not that different. Functional just tries to put more constraints on the developer. Data oriented is also a lot more sensible, and again pretty close to procedural a lot of the time. It's just odd to me this need to separate from procedural at all. Procedural was very honest. If you're a bad programmer you make bad code. If you're a good programmer you make good code. It seems a lot of this was meant to enforce bad programmers to make good code. I'll tell you what I think though. I think that has never worked. It's just hidden it away in some abstraction and made identifying it harder. Much like the code methodologies themselves do to the code.
Now I'm left with a choice, keep my own business going to work on what I love, shift gears and do what I hate for more money, or pivot careers entirely. I decided after all this to go into data science because what you all are doing to the software industry sickens me. And that's my story. It's one that makes a lot of people defensive or even passive aggressive, to those people I say, try more things. At least then you can be less defensive about your opinion.53 -
to the guys saying "oop is dumb" / "i don't need oop" / "i've never worked with oop"...
i have some questions:
- which language are you working with
- which problems are you solving
- how big is your code base
- how do you maintain readability of your code?
don't get me wrong, i don't believe that oop is always the answer. i'm just curious which fields these statements are coming from. if they all come from a low level (assembler, C, ..) or functional languages or "scripty" languages (python, JS), or if there are also people working with languages like C++ where oop is pretty much established. and if the latter, i'm curious how people design their code and what problems they solve... tell me your story :D30 -
My dev lead is a uniquely poor leader with an impressive ability to produce a large amount inflexible, temporarily functional code.
As we're in another pair programming session where I try to keep him from destroying over all type safety and architectural decisions to meet a self imposed demo deadline, he keeps trying to access properties of his state.
This state object is incorrectly typed with an anonymous type with incorrect properties.
Despite repeating calmly stating that the object is incorrectly typed, and that's why there are red underlines when he tries to access a property he knows is in there, he insists that that's not correct.
Finally, he knowingly says that he's figured it out and that he's been doing this for many years.
What was the solution you might ask? (state as any).myProperty;
Truly breathtaking mastery. -
I just released my first NPM package that is actually functional and used in a private project (https://npmjs.com/package/@lbfalvy/...) and I have to say, the quality of debug tooling for Node is abysmal. I spent 4 hours just on Webpack's "Field browser doesn't contain a valid alias configuration" error which simply means "package not found", and then getting Rollup to output a working compiled javascript _and_ a d.ts was its own day-long ordeal.4

For all of youse that ever wanted to try out Common Lisp and do not know where to start (but are interested in getting some knowledge of Common Lisp) I recommend two things:
As an introductory tutorial:
https://lisperati.com/casting.html/
And as your dev environment:
https://portacle.github.io/
Notice that the dev environment in question is Emacs, regardless of how you might feel about it as a text editor, i can recommend just going through the portacle help that gives you some basic starting points regarding editing. Learn about splitting buffers, evaluating the code you are typing in order for it to appear in the Common Lisp REPL (this one comes with an environment known as SLIME which is very popular in the Lisp world) as well as saving and editing your files.
Portacle is self contained inside of one single directory, so if you by any chance already have an Emacs environment then do not worry, Portacle will not touch any of that. I will admit that as far as I am concerned, Emacs will probably be the biggest hurdle for most people not used to it.
Can I use VS Code? Yes, yes you can, but I am not familiar with setting up a VSCode dev environment for Emacs, or any other environment hat comes close to the live environment that emacs provides for this?
Why the fuck should I try Common Lisp or any Lisp for that matter? You do not have to, I happen to like it a lot and have built applications at work with a different dialect of Lisp known as Clojure which runs in the JVM, do I recommend it? Yeah I do, I love functional programming, Clojure is pretty pure on that (not haskell level imo though, but I am not using Haskell for anything other than academic purposes) and with clojure you get the entire repertoire of Java libraries at your disposal. Moving to Clojure was cake coming from Common Lisp.
Why Common Lisp then if you used Clojure in prod? Mostly historical reasons, I want to just let people know that ANSI Common Lisp has a lot of good things going for it, I selected Clojure since I already knew what I needed from the JVM, and parallelism and concurrency are baked into Clojure, which was a priority. While I could have done the same thing in Common Lisp, I wanted to turn in a deliverable as quickly as possible rather than building the entire thing by myself which would have taken longer (had one week)
Am I getting something out of learning Common Lisp? Depends on you, I am not bringing about the whole "it opens your mind" deal with Lisp dialects as most other people do inside of the community, although I did experience new perspectives as to what programming and a programming language could do, and had fun doing it, maybe you will as well.
Does Lisp stands for Lots of Irritating Superfluous Parentheses or Los in stupid parentheses? Yes, also for Lost of Insidious Silly Parentheses and Lisp is Perfect, use paredit (comes with Portacle) also, Lisp stands for Lisp Is Perfect. None of that List Processing bs, any other definition will do.
Are there any other books? Yes, the famous online text Practical Common Lisp can be easily read online for free, I would recommend the Lisperati tutorial first to get a feel for it since PCL demands more tedious study. There is also Common Lisp a gentle introduction. If you want to go the Clojure route try Clojure for the brave and true.
What about Scheme and the Structure and Interpretation of Computer Programs? Too academic for my taste, and if in Common Lisp you have to do a lot of things on your own, Scheme is a whole other beast. Simple and beautiful really, but I go for practical in terms of Lisp, thus I prefer Common Lisp.
how did you start with Lisp?
I was stupid and thought I should start with it after a failed attempt at learning C++, then Java, and then Javascript when I started programming years ago. I was overwhelmed, but I continued. Then I moved to other things. But always kept Common Lisp close to heart. I am also heavy into A.I, Lisp has a history there and it is used in a lot of new and sort of unknown projects dealing with Knowledge Reasoning and representation. It is also Alien tech that contains many things that just seem super interesting to me such as treating code as data and data as code (back-quoting, macros etc)
I need some inspiration man......show me something? Sure, look for a game called Kandria in youtube, the creator, Shimera (Nicolas Hafner) is an absolute genius in the world of Lisp and a true inspiration. He coded the game in Common Lisp, he is also the person behind portacle. If that were not enough, he might very well also be Shirakumo, another prominent member of the Common Lisp Community.
Ok, you got me, what is the first thing in common lisp that I should try after I install the portacle environment? go to the repl and evaluate this:
(+ 0.1 0.2)
Watch in awe at what you get.
In the truest and original sense of the phrase (MIT based) "happy hacking!"10 -
New job is turning out to be kind of the opposite of what I was expecting, based on interviews.
I thought I had done a pretty thorough job asking the kinds of challenging and specific questions during the interviews and was pretty satisfied with the answers.
Three weeks in, I’ve more or less been turned loose onto my first project which is….installing patch updates.
Next few projects through the end of the year and into Q1 next year are similarly sysadmin-chore work, which I’m not going to act like is beneath me or unimportant but it’s not quite what we talked about in the interview when I applied to an SDET position.
Point of order to talk about once I wrap up these first few projects, it doesn’t exactly seem like they know where I’m supposed to be or where to even really put me (on the org chart I have a line reporting up to boss, but I’m also the only one not on a functional team) and reading through the wiki last guy just kind of did everything.
If that’s what this is….eh I need to know if that’s how they want to use me and find out soon.11 -
I hate copyright disclaimer on the top of code files.
I also hate lint-exclude comments.
For the same reason. Both have nothing to do with the code. Both are talking to a system that wraps around our code. Either the linter, that is not part of our code, but part of our continuous integration pipeline or the legal system that governs our living together in whatever country we are.
But for the linter comments and code checker comments and so on, I get it. They are functional. And I do not know how to add information to a line of code without writing into the code in a better way.
But... Does anyone know if the Copyright claim is even valid? Is it functional?
Don't get me wrong. I understand that code has copyright, but is writing it in code even a good method for it?
First I copyright it to myself or the company that I am working for. But that's the norm, isn't it? It's not like someone can look through my code and say: "He forgot to write it on top of this file, we can steal this file."
So if it was missing it wouldn't change anything. It's just so that it is harder for people to claim they haven't known is was copyrighted... Was that even a legal defense in the first place? "Your honor, I was unaware that I violated a valid copyright," seem like the words with which you'd lose a trial.
But then you upload it to Github. And you choose a license. And... It contradicts what you've written in the file. That sounds like a good legal defense. I was looking at that statement, not at this statement. And if you change your mind you have to find hundreds of copyright notices to change it.
Not to speak about the legal system. Is the code protected in the USA? China? Netherlands? Germany? Different legal systems... Maybe different rules...
I know little about law, but I cannot imagine that copyright notices at the top of code files have any real legal power. And it is strangely enough not a topic I find a lot about.
I start believing it's just like when you draw a nice looking vase and somehow scribble van Gogh on it.6 -
Regression testing is a type of software testing that is performed to ensure that changes or modifications made to an existing software application do not have any adverse effects on the functionality of the system. It is typically performed after bug fixes, enhancements, or other changes are made to the software, to ensure that previously working functionality has not been impacted by the changes.
The main objective of regression testing is to ensure that previously working functionality continues to work correctly after any modifications to the software. This involves re-executing test cases that were previously executed to ensure that they still pass, and also adding new test cases to cover any new functionality or changes that have been made.
Regression testing can be performed manually or using automated testing tools. Automated regression testing tools can significantly reduce the time and effort required to execute and maintain regression test suites. Automated tools can also help to identify defects and issues in the software more quickly, allowing for faster feedback and resolution.
Regression testing https://u-tor.com/services/... is a critical component of software development and is essential for ensuring that software applications remain functional and error-free, even after changes have been made to the system.9 -
Things I want to accomplish in 2023:
- learn rust
- learn a functional programming language (elixir probably)
- finish the O'Reilly book about microservices
- learn and contribute to gnunet
- read at least other 2 books about SE
Regarding the last point, I've always underestimated SE books.16 -
I'm learning Rust as a case study for my own programming language. It's funny how many approaches exist to the humble loop.
- In classic procedural languages, a loop's job is to repeat actions, and as such it provides a multitude of tools to control this repetition.
- In all languages with iterators, a for-in loop is a construct that does something with every element of a collection. In languages with both iterators and generator functions, this can even be used to define a sequence in terms of another.
- In Rust, a loop is an expression that obtains its value through repeated execution. It can also be used like a classic loop, of course, but this is the interesting part.
- My little language is a functional language, so "loop" is the Y combinator. To loop means to define the value of an expression in terms of itself. It's the only looping construct, gets special treatment from the type checker and it's also used in recursive type definitions. -
I'd like to hear from developers which prefers Angular to React the reason of said preference.
I want to hear that becasue I like React way more than Angular since I find which is easier to learn (making a form with a React hook is easy while it takes days just to get a grip on Angular forms), it usually takes less code to do things, it doesn't force libraries which may not be necessary for your use case and just makes your bundle bigger (for example most things which are done in NgRx can be done just as easily with regular JS promises without the need of an external tool) and I generally prefer functional programming to OOP.
Said that I want to hear the other side, not to argue but because I want to know cases in which Angular may be a better choice than React to become a better rounded dev.10 -
Class components, although verbose at times, are still far superior than functional components in React. The more I work with React, the more I believe that: Hooks are plain shit.

Finally, I finally got my dream job, but three weeks after starting, I will say I am going into depression.
First, I have to learn a new language (the lang is less than 7 years old) on the job. The language is so different from the paradigm I am used to-from OOP to functional programming, it has very little confusing documentation and a small but growing community.
Though I have been able to show some work, goddamit, it's taking me blood and sand to adjust and be productive.
My onboarding tasks are fixing bugs and implementing a feature, and it has been like walking in a dark tunnel.
I have to face my problem alone as all the devs in the team have swapped.
I rarely sleep, and I recently started to have an existential crisis!
Also, I work part-time on another project, and my output is so poor due to the fact that I am trying to adjust to the new job. Just this evening, I got a call from the manager who was passively aggressive, complaining and asking me to rethink (a passive way of saying "you are fired, if you do not...").
I am feeling anxious. It is taking so much time daily to adjust to the new job.

It's a shame that people don't want to use F# but prise C# for how cool it became and continue becoming. At the same time, little do they know that many of the features were simply drawn from F#.
It's just rediculous how far this OO and C-Style syntax crap has progressed. They keep copying things from functional langugages, making the initial language to be a monstrocity like C++ is now, insted of just using languages like C#. I mean, it was right there before C#: async/task, immutablility, records, indexes, lambdas, non-null by default, who the hell knows what else.
Besides, many people (in my company at least) are just blindly overengineering with patterns and shit, where a simple function would be just enogh.
Watch some some NDC talks about F#, in particular those of Scott Wlaschin. It's just better in so many ways: less noice (I'm looking at you, brackets, commas and semicolons), the whole LOT of type inference and less duplication (just look at the C# signatures of linq methods - it's difficult to read them), immutability by default, non-nullable by default, ADTs and pattern matching, some neat features like type providers (how many times have used "paste special" or an online tool to create C# classes from a JSON/XML file, and how many times have your regenrated it because of schema changes?) and units of measure.
Of course, in some cases it's not optimal, in some cases mutable datastructures of C# are better for performance. But dude, how many performance critical systems have you wrote in C#? I mean, if it comes to performance you should use Rust or C++ or C after all.

I hate the fucking Spring WebFlux and the goddamn Project Reactor on which it depends!
Even debugging a simple CRUD microservice with simple business logic is such a pain in the ass, exception handling has a lot of "magic" implicit stuff which makes me waste hours in fucking trial & error and I have to use very little breakpoints because if a request is paused for more than few seconds it gets terminated.
I love functional programming but why shove it in fucking Java making me waste 90% of my time in trying to guessing what the fucking framework is doing, why not just use Scala which runs in the JVM? We don't even need compatibility with legacy code since it's a greenfield project!
And before you ask yes, I read a fucking book about Project Reactor and Java reactive programming and a lot of docs on Spring, Spring Boot and Spring Web Flux.2 -
Any recommendations for a first timer of functional programming? Not sure what languages are used the most or have the most community support. For whatever it's worth, I've enjoyed working with C# and Golang, and disliked working with JS and PHP.5

what would you guys say is the archetypal functional language, the one we should pick to learn functional programming?4

Finally, I just received an OTP message that said it will be expired in 10 minutes.
Funny part is that i was trying to login 2 hours ago at thier(new client) platform to review.
And they said it is fully functional and you will have to fix some minor issues only.
I am thinking this way( it is so secure that you received otp only after it is expired).😅1 -
I’ve abandoned the classic for loop from my tool belt for quite a long time now. The vast majority of the code is functional.
But today I’ve encountered a problem where I’m considering to use the imperative for loop again because I can’t come up with a good functional approach.
Maybe you guys have an idea.
I have a list of items and I want to make a new list which is like the original list, but it has extra items in between of some other items.
The tricky part is that there is a condition that needs to be checked for each pair of items to determine if the new item should be inserted in between. Otherwise nothing should be inserted.63 -
Why did my perfectly functional Windows 10 OS mapped network drive suddenly decide to have an incorrect username and/or password ?
It was working fine yesterday, and every single network drive I've ever created as worked fine since the dawn of time !
But today, no..
Delete and recreate, its fine..
So, I wondered what happened to break it ?3 -
Honestly my midterm project from college. It was never a production project just supposed to go into my portfolio. Who knew that building a functional social media app in 3 months in a language you never knew is actually SO IMPRESSIVE to people that it alone gets you an internship and a job.2

My two main grudges against Typescript:
1) Union types can't be passed as arguments if there is a variant for every element of the union
2) No tuple polymorphism, i.e. [T, U] isn't assignable to [T]. This is not a mistake because the length of the arrays differs and therefore they may be interpreted in a different way, but IMO there should be a tuple type which is actually an array but length is unavailable and it supports polymorphism. This sounds stupid, but since function parameter lists work well with tuples it would actually enable a lot of functional tricks that are currently inaccessible.7 -
I am trying to isolate logic in React with functional components. Is it a bad idea to forwardref to a custom object that I use to expose actions? This way I could model the ref behavior from old class-based components where it was perfectly normal to represent a capability as a class method.
-
Is there anything like React Context or Unix envvars in any functional language?
Not global mutable state, but variables with a global identity that I can set to a value for the duration of a function call to influence the behavior of all deeply nested functions that reference the same variable without having to acknowledge them.13 -
Make good progress on Orchid, my pet project, the functional programming language that has no syntax apart from what the macros define. A type system, an interpreter and provisions for a compiler would be nice for a start.
Finish my bachelor's degree on some unspecified part of Orchid, at the current pace that would most likely be just the Hindley-Milner algorithm.
Don't get fired from the gem of a job I have, and move to London because I'm a city rat and the only way I can sleep well apparently is with a tram or drunken people screaming under my window.2 -
JoyRant new TestFlight build 10
Images and gifs are fully functional now! 😄
What’s new:
* Images can be tapped to be shown in fullscreen, zoomable and can be saved
* Gif animations can be uploaded and played in fullscreen
* updating notifications when app becomes active

Is an art director/manager that makes designs for an existing website expected to brief the developer on how he wants his new designs to work? Or is the developer expected to innately understand what his functional desire is from the design itself?
My art director/manager claims that he shouldn't have to log into the backend to see how things relate to one another, and that his designs alone should imply what is intended.
When some design element overlaps an existing image gallery, am I expected to magically know whether this element is singular or partaining to the current image shown?
I want to know whether or not me getting mad at him for not telling me how he wants stuff to work is valid, and whether or not I should demand that he briefs me how his design relate to existing taxonomy.
Am I the bad guy?4 -
Had to face the music and make the jump from Ubuntu 22.04 to Fedora 36. Am I have to say it’s been night and day so far. Everything is snappier. Yeah dnf is very slow in comparison to apt but there’s changes you can make to speed things up and the nifty terminal interface is a great change and helps to make up for the speed issues.
Came with Python 3.10 installed, Gnome and gtk4 apps are nice, fluid and up to date and the random slowdowns, freezing and restarts of Ubuntu running the version of Gnome are nonexistent.
For the life of me I can’t see why Ubuntu would drop the ball like this. I have a Dell XPS 13 developer edition and this is the best it’s ever ran. Even wifi connectivity is better despite of the crap WiFi card that ships with this machine.
I want to love this version and while it is the most graphical appealing and functional version of Ubuntu I’ve ever used. The memory management issues make it damn near unusable.10 -
A philosophical question about maintenance/updating.
There is no need to repeat the reasons we need to update our dependencies and our code. We know them/ especially regarding the security issues.
The real question is , "is that indicates a failure of automation"?
When i started thinking about code, and when also was a kid and saw all these sci fi universes with robots etc, the obvious thing was that you build an automation to do the job without having to work with it anymore. There is no meaning on automate something that need constant work above it.
When you have a car, you usually do not upgrade it all the time, you do some things of maintance (oil, tires) but it keeps your work on it in a logical amount.
A better example is the abacus, a calculating device which you know it works as it works.
A promise of functional programming is that because you are based on algebraic principles you do not have to worry so much about your code, you know it will doing the logical thing it supposed to do.
Unix philosophy made software that has been "updated" so little compared to all these modern apps.
Coding, because of its changeable nature is the first victim of the humans nature unsatisfying.
Modern software industry has so much of techniques and principles (solid, liquid, patterns, testing that that the air is air) and still needs so many developers to work on a project.
I know that you will blame the market needs (you cannot understand the need from the start, you have to do it agile) but i think that this is also a part of a problem .
Old devices evolved at much more slow pace. Radio was radio, and still a radio do its basic functionality the same war (the upgrades were only some memory functionalities like save your beloved frequencies and screen messages).
Although all answers are valid, i still feel, that we have failed. We have failed so much. The dream of being a programmer is to build something, bring you money or satisfaction, and you are bored so you build something completely new.14 -
A year ago I built my first todo, not from a tutorial, but using basic libraries and nw.js, and doing basic dom manipulations.
It had drag n drop, icons, and basic saving and loading. And I was satisfied.
Since then I've been working odd jobs.
And today I've decided to stretch out a bit, and build a basic airtable clone, because I think I can.
And also because I hate anything without an offline option.
First thing I realized was I wasn't about to duplicate all the features of a spreadsheet from scratch. I'd need a base to work from.
I spent about an hour looking.
Core features needed would be trivial serialization or saving/loading.
Proper event support for when a cell, row, or column changed, or was selected. Necessary for triggering validation and serialization/saving.
Custom column types.
Embedding html in cells.
Reorderable columns
Optional but nice to have:
Changeable column width and row height.
Drag and drop on rows and columns.
Right click menu support out of the box.
After that hour I had a few I wanted to test.
And started looking at frameworks to support the SPA aspects.
Both mithril and riot have minimal router support. But theres also a ton of other leightweight frameworks and libraries worthy of prototyping in, solid, marko, svelte, etc.
I didn't want to futz with lots of overhead, babeling/gulping/grunting/webpacking or any complex configuration-over-convention.
Didn't care for dom vs shadow dom. Its a prototype not a startup.
And I didn't care to do it the "right way". Learning curve here was antithesis to experimenting. I was trying to get away from plugin, configuration-over-convention, astronaut architecture, monolithic frameworks, the works.
Could I import the library without five dozen dependancies and learning four different tools before getting to hello world?
"But if you know IJK then its quick to get started!", except I don't, so it won't. I didn't want that.
Could I get cheap component-oriented designs?
Was I managing complex state embedded in a monolith that took over the entire layout and conventions of my code, like the world balanced on the back of a turtle?
Did it obscure the dom and state, and the standard way of doing things or *compliment* those?
As for validation, theres a number of vanilla libraries, one of which treats validation similar to unit testing, which seems kinda novel.
For presentation and backend I could do NW.JS, which would remove some of the complications, by putting everything in one script. Or if I wanted to make it a web backend, and avoid writing it in something that ran like a potato strapped to a nuclear rocket (visual studio), I could skip TS and go with python and quart, an async variation of flask.
This has the advantage that using something thats *not* JS, namely python, for interacting with a proper database, and would allow self-hosting or putting it online so people can share data and access in real time with others.
And because I'm horrible, and do things the wrong way for convenience, I could use tailwind.
Because it pisses people off.
How easy (or hard) would it be to recreate a basic functional clone of the core of airtable?
I don't know, but I have feeling I'm going to find out!1 -
It's me or the "Reactive Functional" Spring WebFlux is a stupid fad? It's hard to train new developers on it, a PITA to debug and there isn't any study which proves which it brings better performance compared to the classic Spring MVC.1

I'd like to learn about functional programming. What books, courses, tutorials or articles would you suggest? I have a good understanding of abstract algebra and I felt the need to learn it because my Typescript is a mess and I visibly don't know what I'm doing.1

It would be awesome if angular releases functional components and signals.

#Suphle Rant 7: transphporm failure
In this issue, I'll be sharing observations about 3 topics.
First and most significant is that the brilliant SSR templating library I've eyed for so many years, even integrated as Suphle's presentation layer adapter, is virtually not functional. It only works for the trivial use case of outputting the value of a property in the dataset. For instance, when validation fails, preventing execution from reaching the controller, parsing fails without signifying what ordinance was being violated. I trim the stylesheet and it only works when outputting one of the values added by the validation handler. Meaning the missing keys it can't find from controller result is the culprit.
Even when I trimmed everything else for it to pass, the closing `</li>` tag seems to have been abducted.
I mail project owner explaining what I need his library for, no response. Chat one of the maintainers on Twitter, nothing. Since they have no forum, I find their Gitter chatroom, tag them and post my questions. Nothing. The only semblance of a documentation they have is the Github wiki. So, support is practically dead. Project last commit: 2020. It's disappointing that this is how my journey with them ends. There isn't even an alternative that shares the same philosophy. It's so sad to see how everybody is comfortable with PHP templating syntax and back end logic entagled within their markup.
Among all other templating libraries, Blade (which influenced my strong distaste for interspersing markup and PHP), seems to be the most popular. First admission: We're headed back to the Blade trenches, sadly.
2nd Topic: While writing tests yesterday, I had this weird feeling about something being off. I guess that's what code smell is. I was uncomfortable with the excessive amount of mocking wrappers I had to layer upon SUT before I can observe whether the HTML adapter receives expected markup file, when I can simply put a `var_dump` there. There's a black-box test for verifying the output but since the Transphporm headaches were causing it to fail, I tried going white-box. The mocking fixture was such a monstrosity, I imagined Sebastian Bergmann's ghost looking down in abhorrence over how much this Degenerate is perverting and butchering his creation.
I ultimately deleted the test travesty but it gave rise to the question of how properly designed system really is. Or, are certain things beyond testing white box? Are there still gaps in the testing knowledge of a supposed testing connoisseur? 2nd admission.
Lastly, randomly wanted to tweet an idea at Tomas Votruba. Visited his profile, only to see this https://twitter.com/PovilasKorop/.... Apparently, Laravel have implemented yet another feature previously only existing in Suphle (or at the libraries Arkitekt and Deptrac). I laughed mirthlessly as I watch them gain feature-parity under my nose, when Suphle is yet to be launched. I refuse to believe they're actually stalking Suphle3 -
What should you do if the project manager is not assigning you any new work after the backlog already has been cleaned up?
I currently work as a junior front-end dev. For the past few weeks, the 2 juniors (incl. me) are lacking tickets. For example, I got 2.5 days of work assigned during our 3-week sprint. We already followed some courses, read some books & created some designs for upcoming features (that have no "functional specifications" written down).3
