Been reviewing ALOT of client code and supplier’s lately. I just want to sit in the corner and cry.
Somewhere along the line the education system has failed a generation of software engineers.
I am an embedded c programmer, so I’m pretty low level but I have worked up and down and across the abstractions in the industry. The high level guys I think don’t make these same mistakes due to the stuff they learn in CS courses regarding OOD.. in reference how to properly architect software in a modular way.
I think it may be that too often the embedded software is written by EEs and not CEs, and due to their curriculum they lack good software architecture design.
Too often I will see huge functions with large blocks of copy pasted code with only difference being a variable name. All stuff that can be turned into tables and iterated thru so the function can be less than 20 lines long in the end which is like a 200% improvement when the function started out as 2000 lines because they decided to hard code everything and not let the code and processor do what it’s good at.
Arguments of performance are moot at this point, I’m well aware of constraints and this is not one of them that is affected.
The problem I have is the trying to take their code in and understand what’s its trying todo, and todo that you must scan up and down HUGE sections of the code, even 10k+ of line in one file because their design was not to even use multiple files!
Does their code function yes .. does it work? Yes.. the problem is readability, maintainability. Completely non existent.
I see it soo often I almost begin to second guess my self and think .. am I the crazy one here? No. And it’s not their fault, it’s the education system. They weren’t taught it so they think this is just what programmers do.. hugely mundane copy paste of words and change a little things here and there and done. NO actual software engineers architecture systems and write code in a way so they do it in the most laziest, way possible. Not how these folks do it.. it’s like all they know are if statements and switch statements and everything else is unneeded.. fuck structures and shit just hard code it all... explicitly write everything let’s not be smart about anything.
I know I’ve said it before but with covid and winning so much more buisness did to competition going under I never got around to doing my YouTube channel and web series of how I believe software should be taught across the board.. it’s more than just syntax it’s a way of thinking.. a specific way of architecting any software embedded or high level.
Anyway rant off had to get that off my chest, literally want to sit in the corner and cry this weekend at the horrible code I’m reviewing and it just constantly keeps happening. Over and over and over. The more people I bring on or acquire projects it’s like fuck me wtf is this shit!!! Take some pride in the code you write!16 -
WASM was a mistake. I just wanted to learn C++ and have fast code on the web. Everyone praised it. No one mentioned that it would double or quadruple my development time. That it would cause me to curse repeatedly at the screen until I wanted to harm myself.
The problem was never C++, which was a respectable if long-winded language. No no no. The problem was the lack of support for 'objects' or 'arrays' as parameters or return types. Anything of any complexity lives on one giant Float32Array which must surely bring a look of disgust from every programmer on this muddy rock. That is, one single array variable that you re-use for EVERYTHING.
Have a color? Throw it on the array. 10 floats in an object? Push it on the array - and split off the two bools via dependency injection (why do I have 3-4 line function parameter lists?!). Have an image with 1,000,000 floats? Drop it in the array. Want to return an array? Provide a malloc ptr into the code and write to it, then read from that location in JS after running the function, modifying the array as a side effect.
My- hahaha, my web worker has two images it's working with, calculations for all the planets, sun and moon in the solar system, and bunch of other calculations I wanted offloaded from the main thread... they all live in ONE GIANT ARRAY. LMFAO.If I want to find an element? I have to know exactly where to look or else, good luck finding it among the millions of numbers on that thing.
And of course, if you work with these, you put them in loops. Then you can have the joys of off-by-one errors that not only result in bad results in the returned array, but inexplicable errors in which code you haven't even touched suddenly has bad values. I've had entire functions suddenly explode with random errors because I accidentally overwrote the wrong section of that float array. Not like, the variable the function was using was wrong. No. WASM acted like the function didn't even exist and it didn't know why. Because, somehow, the function ALSO lived on that Float32Array.
And because you're using WASM to be fast, you're typically trying to overwrite things that do O(N) operations or more. NO ONE is going to use this return a + b. One off functions just aren't worth programming in WASM. Worst of all, debugging this is often a matter of writing print and console.log statements everywhere, to try and 'eat' the whole array at once to find out what portion got corrupted or is broke. Or comment out your code line by line to see what in forsaken 9 circles of coding hell caused your problem. It's like debugging blind in a strange and overgrown forest of code that you don't even recognize because most of it is there to satisfy the needs of WASM.
And because it takes so long to debug, it takes a massively long time to create things, and by the time you're done, the dependent package you're building for has 'moved on' and find you suddenly need to update a bunch of crap when you're not even finished. All of this, purely because of a horribly designed technology.
And do they have sympathy for you for forcing you to update all this stuff? No. They don't owe you sympathy, and god forbid they give you any. You are a developer and so it is your duty to suffer - for some kind of karma.
I wanted to love WASM, but screw that thing, it's horrible errors and most of all, the WASM heap32.7 -
Did some updates to an older Web Forms website built by a previous SENIOR developer who is a notoriously horrible developer.
Now before I start, you have to understand this guy studied at a University and had been working for at least two years before I even started working. He is supposed to know the basic shit mentioned below.
This also happened a couple of days ago, so I have calmed down since then so I apologise for the relaxed tone. My next rant will contain a lot more swearing.
This fucking guy did the stupidest shit imaginable.
On the details view of a post|page|article|product|anything that would require a details view this jackass would load the data from the DB.
Using an OleDbConnection, OleDbDataAdapter, DataTable and the poorest writter fucking sql statements you have ever seen. All of these declared in the Page_Load method.
There was literally no reason for him to use OleDb instead of Sql, but he simply did not know any better.
He especially liked: "select * from tbl where id = " & Request("T") & ""
ZERO fucking checks to see if the value is even passed or valid, nothing. He did not even check whether the DataTable had any rows.
He then proceeded to use only the Heading column of the returned row to change the page's title.
Stupidly I assumed the aspx page will be in a better state. Fuck NO!
This fucktard went, added server tags to the opening of the asp:Content tag, copied that shit he used to fetch the data and pasted it between the server tags.
He did not know how to access the DataTable mentioned above from the aspx page!
He did this on every fucking project he worked on. Any place that required <%= %> to display data instead of using asp server controls, this cunt copied whatever was written in the code behind and pasted everything between server tags.
Fuck I could go on forever, but I think this is enough for my first rant.2 -
I fucking hate chained methods. Ok, not all of them. Query things like array.where.first... that stuff is ok.
Specially if it's part of the std lib of a lang, which would be probably written by a very competent coder and under scrutiny.
But if you're not that person, chances are you'll produce VASTLY inferior code.
I'm talking about things like:
expect(n).to.be(x).and.not(y)
And the reason I don't like it is because it's all fine and dandy at first.
But once you get to the corner cases, jesus christ, prepare to read some docpages.
You end up reading their entire fucking docs (which are suboptimal sometimes) trying to figure if this fucking dsl can do what you need.
Then you give up and ask in a github issue. And the dev first condescends you and then tells you that the beautiful eden of code he created doesn't let you do what you want.
The corner cases usually involve nesting or some very specific condition, albeit reasonable.
This kind of design is usually present in testing or validation js libraries. And I hate all of those for it.
If you want a modern js testing lib that doesn't suck ass, check avajs. It's as simple as testing should be.
No magic globals, no chaining, zero config. Fuck globals forced by libs.
But my favorite thing about it that is I can put a breakpoint wherever the fuck I want and the debugger stops right fucking there.
Code is basically lines of statements, that's it, and by overusing chaining, by encouraging the grouping of dozens of statements into one, you are preventing me from controlling these statements on MY code.
As an end dev, I only expect complexity increases to come from the problems themselves rather than from needlessly "beautified" apis.
When people create their own shitty dsl, an image comes to my mind of an incoherent rambling man that likes poetry a lot and creates his own martial art, which looks pretty but will get your ass kicked against the most basic styles of fighting.
I fucking hate esoteric code.
Even if I had to execute a list of functions, I'd rather send them in an array instead of being able to chain them because:
a) tree shaking would spare from all the functions i didn't import
b) that's what fucking arrays are for, to contain several things.
This bad style of coding is a result of how low the barrier to code in higher level langs are.
As a language or library gets easier to use you might think that's a positive thing. But at the same time it breeds laziness.
Js has such a low learning curve that it attacts the wrong kind of devs, the lazy, the uninspired, the medium.com reader, the "i just care about my paycheck" ones.
Someone might think that by bashing bad js devs I'm trying to elevate myself.
That'd be extremely stupid. That's like beating a retarded blind man in a game and then saying "look, I'm way better than this retarded blind man".
I'm not on a risky point of view, just take a stroll down npmjs.com. That place is a landfill. Not really npm's fault, in fact their search algorithm is good.
It's just the community.
Every lang has a ratio of competence. Of competent to incompetent devs.
You have the lang devs and most intelligent lib devs at the top. At the bottom you have the bottom.
Well js has a horrible ratio. I wouldn't be shocked to find out that most js devs still consider using import or await the future.
You could say that js improved a lot, that it was way worse beforr. But I hate chaining now, and i hated back then!
On top of this, you have these blog web companies, sucking the "js tutorial" business tit dry, pumping out the most obscenely unprofessional and bar lowering tutorials you can imagine, further capping the average intelligence of most js devs.
And abusing SEO while they're at it, littering the entire web with copy paste content.2 -
Not sure if it's the worst code review but it's a recent one.
We don't really do code reviews where I work unfortunately but my coworker used my framework for the first time (build some nice composer libraries for cmdline projects) and asked if I could make them do autoloading.
He never used namespaces before so I was glad to help him out.
What I saw was a dreadful mess. His project was called "scripts" so good luck picking a namespace...
Than it was all lose functions in the executable file. All those functions are however called by a class in another file (if they where not calling eachother as a cascading mess). That class was extending an abstract class from my library as instructed. However I never imagined my lib being raped like that.
The functions themselves are a horrible mess. Nothing uniform completely different style (our documentation states PSR's should be used).
Parameters counts higher than 5.
Variable names like Object and Dobject (in calling function Dobject is Object but it needs a fresh one.
If statements on parameters that need basically split it in two (should simply be to functions)
If else statement with return of same variable as a single line (sane people use ternary for that)
Note that I said functions. All of it should have been OO and methods. Would have saved at least some of the parameter hell.
I could go on and on. Do I think the programmer is bad yes (does not even grasp interfaces, dep injection, foreach loops). Is this his best work no. He said that for a one of script like this it just has to work. Not going to be used elsewhere. I disagree as it is a few thousand lines of code that others have to read too.2 -
I had this problem where I needed to make a script that took two values, and from that printed what card was faulty in a pretty large system.
As the script language is horrible, I could not be bothered to manually write over 3000 if-statements I proceeded to write a program that writes code for me, based on a export of all the cards.
There are few things I have experienced in my life that compares to the satisfaction of seeing my own program produce many thousands of lines of code in a few seconds.2 -
Just went over some of my old horrible code from before i started studying. I litterally went from 104 lines of if/else statements to about 15 lines with loops. Then down to 2 lines with lambdas...
I saved 102 lines of actual code. And the runtime! I had a loop count to 10000 with no body! It helps to study apparently :/
