1. Have some issue with my code which spits out cryptic compiler error.

2. Ask on stack overflow, Reddit, etc for a solution.

3. Get scolded at for "not reading the documentation" and "asking questions which could be answered by just Googling". Still no clue what I'm doing wrong, or what the solution would be.

4. Find someone else's vaguely related problem.

5. Post my problematic code as the answer, with arrogant comment about OP being a retard for not figuring that out for themselves.

6. A dozen angry toxic nerds flock in to tell me how retarded and wrong I am, correcting me... solving my original problem.

7. Evil plan succeeded, my code compiles, and as a bonus I made the internet a worse place in the process.

I think if you tell a bunch of autistic neckbeards that "all coronaviruses are fundamentally incurable", you'd have a vaccine within a week.

Let the student use their own laptops. Even buy them one instead of having computers on site that no one uses for coding but only for some multiple choice tests and to browse Facebook.

Teach them 10 finger typing. (Don't be too strict and allow for personal preferences.)

Teach them text navigation and editing shortcuts. They should be able to scroll per page, jump to the beginning or end of the line or jump word by word. (I am not talking vi bindings or emacs magic.) And no, key repeat is an antifeature.

Teach them VCS before their first group assignment. Let's be honest, VCS means git nowadays. Yet teach them git != GitHub.

Teach git through the command line. They are allowed to use a gui once they aren't afraid to resolve a merge conflict or to rebase their feature branch against master. Just committing and pushing is not enough.

Teach them test-driven development ASAP. You can even give them assignments with a codebase of failing tests and their job is to make them pass in the beginning. Later require them to write tests themselves.

Don't teach the language, teach concepts. (No, if else and for loops aren't concepts you god-damn amateur! That's just syntax!)

When teaching object oriented programming, I'd smack you if do inane examples with vehicles, cars, bikes and a Mercedes Benz. Or animal, cat and dog for that matter. (I came from a self-taught imperative background. Those examples obfuscate more than they help.) Also, inheritance is overrated in oop teachings.

Functional programming concepts should be taught earlier as its concepts of avoiding side effects and pure functions can benefit even oop code bases. (Also great way to introduce testing, as pure functions take certain inputs and produce one output.)

Focus on one language in the beginning, it need not be Java, but don't confuse students with Java, Python and Ruby in their first year. (Bonus point if the language supports both oop and functional programming.)

And for the love of gawd: let them have a strictly typed language. Why would you teach with JavaScript!?

Use industry standards. Notepad, atom and eclipse might be open source and free; yet JetBrains community editions still best them.

For grades, don't your dare demand for them to write code on paper. (Pseudocode is fine.)

Don't let your students play compiler in their heads. It's not their job to know exactly what exception will be thrown by your contrived example. That's the compilers job to complain about. Rather teach them how to find solutions to these errors.

Teach them advanced google searches.

Teach them how to write a issue for a library on GitHub and similar sites.

Teach them how to ask a good stackoverflow question :>

Interesting bug hunt!

Got called in because a co-team had a strange bug and couldn't make sense of it. After a compiler update, things had stopped working.

They had already hunted down the bug to something equivalent to the screenshot and put a breakpoint on the if-statement. The memory window showed the memory content, and it was indeed 42. However, the debugger would still jump over do_stuff(), both in single step and when setting a breakpoint on the function call. Very unusual, but the rest worked.

Looking closer, I noticed that the pointer's content was an odd number, but was supposed to be of type uint32_t *. So I dug out the controller's manual and looked up the instruction set what it would do with a 32 bit load from an unaligned address: the most braindead thing possible, it would just ignore the lowest two address bits. So the actual load happened from a different address, that's why the comparison failed.

I think the debugger fetched the memory content bytewise because that would work for any kind of data structure with only one code path, that's how it bypassed the alignment issue. Nice pitfall!

Investigating further why the pointer was off, it turned out that it pointed into an underlying array of type char. The offset into the array was correctly divisible by 4, but the beginning had no alignment, and a char array doesn't need one. I checked the mapfiles and indeed, the old compiler had put the array to a 4 byte boundary and the new one didn't.

Sure enough, after giving the array a 4 byte alignment directive, the code worked as intended.

One of the most infuriating ideas in software development culture is that you can build maintainable applications without a strictly enforced type system and structured data.

Sure, it's more fun to wack around a dynamically typed system until it works or to write a major application with mutable datastructures... It's a least fun until a few years in and you have to debug an unexpected overwrite or a inconsistent use of an object property or whatever.

Anyone who writes maintainable code eventually figures out that you need rules and procedures, the issue with JavaScript, python, ruby, lisp, etc developers is that they think it's us developers that needs to enforce these rules instead of the compiler (which is infinitely better at it).

"And in a stunning turn of events, he got it to work!"

But seriously... I've literally been throwing shit at a wall and seeing what would stick.
Fucking DTOs and getting shit out of a database. I need better resources on how to do this properly!

Anyways, I found that just using 'object' and letting the compiler deal with the rest of the bullshit actually allowed my code to work and run. I'm still a little in shock.

I'm over here trying to keep things in a nice one-to-one because that's what my PM recommended... and instead I just get slammed by Type casting nonsense and more errors than I can begin to understand. And unfortunately, Stackoverflow is of no help because everyone's issues are very nuanced and unrelated to my problem... Maybe I'm the problem? 🤷

But here it is working without all that bullshit. I don't know man... This code base is not the rager I was expecting. I'm getting my ass kicked with code that doesn't fall in line with the book I'm learning from.

You know how they say, "forget everything you've read and learned"? I'm feeling that really hard right now.

Constantly fighting the urge to rip everything down and do it based on what my book is recommending, but then the logical natured side of me is like "you ain't got that kind of time to be unfucking someone's work, only to get caught in more trouble. Your ego is not worth it"

Anyways, it's fucking late here and I'm glad enough to not have to think about this issue anymore. Bye.

How the fuck does TypeScript still not have service worker support? Seriously, it's just a typings file. People have written that typings file. They would just have to include it in the lib collection shipped with the compiler. Yeah, it would have DOM calls intermixed with the SW api, but frankly, having the typings for a set of calls you can't use is infinitely better than missing them for a set of calls you can.
The relevant issue is 5 years old btw.

Scala. The compiler is slow; sbt is buggy; too much syntactic sugar; implicits; cryptic; unreadable; and my biggest issue, symbols are reused and their use changes depending on how they are used, let's look at _:
As an existential type, as higher kind type parameter, as ignored variables, as ignored parameters, as ignored names of self types, as wildcard patterns, as wildcard imports, as hiding imports, for joining letters to punctuation, as assignment operators, as placeholder syntax, in partially applied functions, when converting call-by-name parameters to functions.

Compilers should just work for raw C with only static memory allocation. This isn't the bad old days where a couple of dudes wrote a short book explaining how C might probably should possibly work. I hear supposedly we have standards now.

Well, last week I lost 2 days to our compiler randomly forgetting that it wasn't okay to put a globally allocated uint32 at an address ending in 9. What? It had been handling this case without issue for more a year, but now after changing completely unrelated code we have this problem.

I'm not sure how to even deal with this idiocy so no doubt I'll continue working on it this week, too.

Thanks a lot, GCC.

So I figure since I straight up don't care about the Ada community anymore, and my programming focus is languages and language tooling, I'd rant a bit about some stupid things the language did. Necessary disclaimer though, I still really like the language, I just take issue with defense of things that are straight up bad. Just admit at the time it was good, but in hindsight it wasn't. That's okay.

For the many of you unfamiliar, Ada is a high security / mission critical focused language designed in the 80's. So you'd expect it to be pretty damn resilient.

Inheritance is implemented through "tagged records" rather than contained in classes, but dispatching basically works as you'd expect. Only problem is, there's no sealing of these types. So you, always, have to design everything with the assumption that someone can inherit from your type and manipulate it. There's also limited accessibility modifiers and it's not granular, so if you inherit from the type you have access to _everything_ as if they were all protected/friend.

Switch/case statements are only checked that all valid values are handled. Read that carefully. All _valid_ values are handled. You don't need a "default" (what Ada calls "when others" ). Unchecked conversions, view overlays, deserialization, and more can introduce invalid values. The default case is meant to handle this, but Ada just goes "nah you're good bro, you handled everything you said would be passed to me".

Like I alluded to earlier, there's limited accessibility modifiers. It uses sections, which is fine, but not my preference. But it also only has three options and it's bizarre. One is publicly in the specification, just like "public" normally. One is in the "private" part of the specification, but this is actually just "protected/friend". And one is in the implementation, which is the actual" private". Now Ada doesn't use classes, so the accessibility blocks are in the package (namespace). So guess what? Everything in your type has exactly the same visibility! Better hope people don't modify things you wanted to keep hidden.

That brings me to another bad decision. There is no "read-only" protection. Granted this is only a compiler check and can be bypassed, but it still helps prevent a lot of errors. There is const and it works well, better than in most languages I feel. But if you want a field within a record to not be changeable? Yeah too bad.

And if you think properties could fix this? Yeah no. Transparent functions that do validation on superficial fields? Nah.

The community loves to praise the language for being highly resilient and "for serious engineers", but oh my god. These are awful decisions.

Now again there's a lot of reasons why I still like the language, but holy shit does it scare me when I see things like an auto maker switching over to it.

The leading Ada compiler is literally the buggiest compiler I've ever used in my life. The leading Ada IDE is literally the buggiest IDE I've ever used in my life. And they are written in Ada.

Side note: good resilient systems are a byproduct of knowledge, diligence, and discipline, not the tool you used.

A bit confused

I have a code and it is giving different answers in different language and compilers
the code is

Int a=4
Int b = ++a + a++ + --a

Please ignore the syntactical errors
But this logic give different answers in different compiler and language like in
C(turbo c++ compiler) it gives 12
C(gcc)- 16
Java- 15
Python- 12

Can anybody explain the logic behind this...

Compiler Question

Things you hate/don't like about JS/Javascript/ECMAscript/ES. Or what do you think are the issues

I spent the whole damn day trying to setup grpc-web, but this protocol is documented so damn poorly!

You manage to set grpc up for one language and it’s all cool, then you stupidly think that you are free to reuse the compiler you used for the nodejs version for your frontend part but nope! Our web module is now deprecated, please use this module instead!

“Ah yes just clone the repo and check out (…) and you can also check this link whic is in no way highlighted in the middle of a wall of text (…)”

*checking the other page*
Ah yes you need to install a package available only on your unix machine (great! Screw the devs in my team who use windows I guess, they’ll be happy to hear this!) and don’t forget to clone this repo to build your own plugin! And by that I ofc mean to compile it on your own!

- compiler error
After digging for an hour you find a requirement in an obscure issue opened and closed cause “ah yes we have a dependency not stated anywhere” *close issue and never add it to the project*

Fine, fine I can survive this bs

- another compiler error, no solution found after 2 hours

Honestly? Why the fuck do I need to compile this stuff? Just give me a damn npm package I can use? Goddamn it’s just transpiling, you don’t need access to my OS! (Aside for fs to save the files, and which btw is accessible via nodejs)

Now, I COULD download the latest realease as a precompiled, but… honestly?
I give up, I’ll do some shitty rest apis cause the customer’s not paying me enough for even THINKING to go trough this shit again when they’ll ask an iOS app. Or having colleagues asking me to help them understand how to do it.

Side note: also add typescript support to the web-code-generation ffs! Why does node have it and web don’t?

It's been 2 years since I got a result for an issue while googling. Whenever I post something on SO I get 0 responses because no one knows :(

Highly optimized code, compiler errors and working with "new stuff" ftl :(

Question for iOS Swift guys:

Since Implicitly Unwrapped Optionals are now dropped for a while, and everything is an optional, hiw can I now declare property that has no value and intializer will not make fuss?

I used to do this:

class Bullet {
var calibre: Double!
}

This way I can avoid initializer which gets useful when there are properties which hold complex types, which get useful when writing tests.

If I remove ! Then compiler complains.
If I put ? Then My code becomes crap of guards and ifs to check for optionals.

Really hate this Optional thing in Swift. Half my time when I jave an issue is related to optionals.

Btw,
let x: Int! = 10
let y = x, yields y: Int?

I don't know what's happening. In passing a char pointer to a function. I'm having issue, so I'm printf'ing the address pointed to by the pointer. Right after I assign it, it contains the right address, but the printf on the next line has it containing a different address. Another printf shows another different value, but all the following printfs show that third value. They're all consecutive printfs with nothing happening in between in the program, and the char* starts it's life as an array. All compiler optimizations are disabled. I don't know what's happening, it's just randomly changing. 😭

Not exactly a rant but some annoyances

Whenever I copy paste code from kindle it does not space the code. Stack overflow says that kindle is using characters for space which are not present in UTF-8 which causes the issue and the find and replace option coes not work in vs code which the author is using. And if you copy from kindle whether you use the button or Ctrl + C it will add the book title and the author at the end. Who the fuck though this was a good idea.

Oh a table does not fit on the screen render whatever fits even if it is the top line of the table. This is probably not an issue and they cannot fix it and I shoild just deal with it.

The author introduces me to the language compiler and lists a command to what versions are available. I get an error which says the command is not found on windows. I dont find any solutions on google, so I go the next place and author says that he knows about it and shows a link to fix it and tells to folloe the instructions. But the link does not have any instructions and just has instructions to configure the compiler itself. The only releveant information was the path to the compiler which the author could have included there or said that was the only relevant information. The path was correct but I needed to install some stuff through Visual Studio
