Nobody knows

I believe it’s /var/lib/apport/coredump on Ubuntu.

you can set it

tl;dw: writes to the path in /proc/sys/kernel/core_pattern

If you are using systemd, there’s a tool called coredumpctl.

Super-advanced java devs like me do it like try{} catch (Exception e) { System.out.println("something went wrong"); e.printStackTrace(); }

you can follow any exception down to the exact line of code

Which is usually not a piece of code written by us and is caused by another piece of code not written by us either

but you can follow any exception down to the exact line of code (or JNI call, I guess) where the problem occurs.

But, it’s not really where the problem occurred. How often do you get a stack trace and the bug fix is at the line referenced by the stack trace? Almost never. It’s more that it takes you down to the exact line of code where the effects of the problem are bad enough to affect the running of the program. But, the actual problem happened earlier, sometimes much earlier.

For example, NullPointerException isn’t actually the problem, it’s a symptom of the problem. Something didn’t get initialized properly, and nobody noticed for a while, until we tried to use it, and got a null pointer. Sometimes it’s easy to go from the effect (null pointer) to the cause (uninitialized thing). But, other times that “thing” was passed in, so you have to work backwards to try to figure out where that thing comes from, and why it’s in that broken state.

Sure, it’s better than nothing, but it’s still frustrating.

It’s not bad. It’s better than what most languages give you

The same applies to using the core dump.

In fact, the Python one is the lest useful of the trio.

Ah, good old PlarformIO

Some people use tabs for indentation and spaces for alignment. It kind of gets the pros of tabs (user configurable indent-width) and the pros of spaces (alignment). That doesn’t work in Python where you can’t align stuff and the interpreter doesn’t allow mixing tabs with spaces, but in other languages it is a possible style.

Raw adjust with tabs, fine adjust with spaces.

Don’t laugh, people are actually doing that.

Rust compiler is passive agressive, like:

“There’s an error at line 286 because you still don’t know how to use the borrow checker after all this time ♥️”

I need a rust compiler in my life 😍

Damn right. And once it compiles… it works.

The rust compiler produces a flawless understanding of your code, and then quits out because understanding that code is a Nightly-only feature and you’re using the stable build.

except when it gives errors about lifetimes of some object.

boy, that makes my brain hurt

I don’t know from where this legend comes from but lifetimes/concurrency/macros errors are brain-hurting.

Most of the time I find myself dropping project because I wrote my program in a correct way but Rust just does not like how it is designed lol. I can’t get shit done with this language

I use gdb with great success for x64, rv64, and c:

info registers rip or just setup tui:

# ~/.config/gdb/gdbinit:
tui new-layout default regs 1 {-horizontal src 1 asm 1} 2 status 0 cmd 1
tui layout default
tui enable

I honestly vastly prefer using IDA and Windows specific tools (x64dbg) over gdb. IDA can interface with gdb so it can act as a frontend which can be handy for visualization.

Can’t believe that my code is racist smh

Ho hoo, that isn’t smoke, it’s steam, from the steamed rams we’re having! Mmm, steamed rams.

And the people hating on it somehow never used any version above 8, which is 10 years old and EOL.

and inspired C#, which is pretty rad! (humble opinion… preparing for downvotes because I don’t get the feeling lemmy is where M$ devs hang out)

You only named one upside, I can’t think of any other, and C-like syntax is pretty common, so it’s not much of an upside. It’s at least debatable whether the JVM is a good thing at all - the majority of languages get along perfectly well without it, and there’s no reason to believe the ones that do target it wouldn’t be doing just fine if it didn’t exist. It’s weird to say Java gave a job to anybody - the demand to have software written resulted in programmers being hired; if Java hadn’t been pushed on the market by Sun, it would have just been another language. Java didn’t establish any fundamentals at all, it just borrowed from other places. While all three of the other languages you mention are interesting, for sure, I’m not sure why somebody who doesn’t like Java should limit themselves to JVM languages.

Opinion bad

Good gods, a long-form content creator! Will be checking this out later

tsoding’s channel is one I look forward to watching every single day, never a dull moment in his streams/videos.

If you’re someone who likes to watch things live, his Twitch channel is available here.

he’s russian tho

I meant faster than Python, not faster than Rust. Rust is fast.

C++ iirc is used mostly for microprocessor code

lol no, it’s used almost everywhere where performance is important and people want(ed) OOP, from tiny projects to web browsers (Chrome, Firefox) to game engines (Unreal, CryEngine). Many of these are hugely complex and do encounter segfaults on a somewhat frequent basis.

Saying C++ is mostly used for embedded applications is like saying C# is mostly used for scripting games, i.e. it doesn’t nearly cover all the use cases.

higher-level languages also exist

This depends on your definition of “higher-level”, but many people would argue that C++ is on a similar level to Java or C# in terms of abstraction. The latter two do, however, have a garbage collector, which vastly simplifies memory management for the programmer(generally anyway).

It’s also used for basically any AAA game

I also currently use it for a new project since all needed 3rd party libraries are from a very specific domain and the project has a deadline, so writing and testing wrappers for Rust that would provide me with any meaningful advantages down the road are too costly to budget for before the deadline.

That could become part of a future refactoring, though.

Well yes, that’s a pretty good way of debugging a third party app but if you are developing something you can have more ease with gdb attached

Great fun and a good way to brush up on your assembly skills

Just load it on the debugger and leave your asm skill gather patina.
