I use EndeavourOS and really enjoy it. It’s effectively Arch but without the fuss. You get a GUI with just a few steps to set it up and you’re good to go. I tend to upgrade once a week, while checking the forums to see nothing too bad broke. That’s basically the maintenance I have.
When I do a new install on a new device, I just clone a repo I keep with the most important config files. Then I copy them to where they belong. There’s really not much more to it.
Using smart pointers doesn’t eliminate the memory safety issue, it merely addresses one aspect of it. Even with smart pointers, nothing is preventing you from passing references and using them after they’re freed.
I think that’s very team/project dependent. I’ve seen it done before indeed, but I’ve never been on a team where it was considered idiomatic.
This does look cool. How would it work together with Steam Input?
I don’t know about your workplace, but if at all possible I would try to find time between tasks to spend on learning. If your company doesn’t have a policy where it is clear that employees have the freedom to learn during company time, try to underestimate your own velocity even more and use the time it leaves for learning.
About 10 years ago I worked for a company where I was performing quite well. Since that meant I finished my tasks early, I could have taken on even more tasks. But I didn’t really tell our scrum master when I finished early. Instead I spent the time learning, and also refactoring code to help me become more productive. This added up, and my efficiency only increased more, until at some point I only needed one or two days to complete a week’s sprint. I didn’t waste my time, but I used it to pick up more architectural stuff on the side, while always learning on the job.
I’ll admit that when I started this route, I already had a bunch of experience under my belt, and this may not be feasible if you have managers breathing down your neck all the time. But the point is, if you play it smart you can use company time to improve yourself and they may even appreciate you for it.
If we’re looking at it from a Rust angle anyway, I think there’s a second reason that OOP often becomes messy, but less so in Rust: Unlimited interior mutability. Rust’s borrow checker may be annoying at times, but it forces you to think about ownership and prevents you from stuffing statefulness where it shouldn’t be.
You can use the regular data structures in java and run into issues with concurrency but you can also use unsafe in rust so it’s a bit of a moot point.
In Java it isn’t always clear when something crosses a thread boundary and when it doesn’t. In Rust, it is very explicit when you’re opting into using unsafe, so I think that’s a very clear distinction.
Java provides classes for thread safe programming, but the language isn’t thread safe. Just like C++ provides containers for improved memory safety, and yet the language isn’t memory safe.
The distinction lies between what’s available in the standard library, and what the language enforces.
Modern C++ does use references, which can also reference memory that is no longer available. Avoiding raw pointers isn’t enough to be memory safe.
Try browsing the list of somewhat recent #CVE rated critical, as I just did to verify. A majority of them is not related to any memory errors. Will you tell all them “just use a different programming language”?
I’m sorry, but this has been repeatedly refuted:
And yes, they are telling their engineers to use a different programming language. In fact, even the NSA is saying exactly that: https://www.nsa.gov/Press-Room/News-Highlights/Article/Article/3215760/nsa-releases-guidance-on-how-to-protect-against-software-memory-safety-issues/
It doesn’t come out today, it’s been there for a long time, and it’s standardized, proven and stable.
This seems like an extremely short-sighted red herring. C has so many gaps in its specification, because it has no problem defining things as “undefined behavior” or “implementation defined”, that the standard is essentially useless for kernel-level programming. The Linux kernel is written in C and used to only build with GCC. Now it builds with GCC and LLVM, and it relies on many non-standard compiler extensions for each. The effort to add support for LLVM took them 10 years. That’s 10 years for a migration from C to C. Ask yourself: how is that possible if the language is so well standardized?
Great suggestions! One nitpick:
But in principle I find this quite workable, as you get to write your CI code in Rust.
Having used xtask in the past, I’d say this is a downside. CI code is tedious enough to debug as it is, and slowing down the cycle by adding Rust compilation into the mix was a horrible experience. To add, CI is a unique environment where Rust’s focus on correctness isn’t very valuable, since it’s an isolated, project-specific environment anyway.
I’d rather use Deno or indeed just for that.
No, OP asked for a black and white winner. I was elaborating because I don’t think it’s that black and white, but if you want a singular answer I think it should be clear: Rust.
I would say at this point in time it’s clearly decided that Rust will be part of the future. Maybe there’s a meaningful place for Zig too, but that’s the only part that’s too early to tell.
If you think Zig still has a chance at overtaking Rust though, that’s very much wishful thinking. Zig isn’t memory safe, so any areas where security is paramount are out of reach for it. The industry isn’t going back in that direction.
I actually think Zig might still have a chance in game development, and maybe in specialized areas where Rust’s borrow checker cannot really help anyway, such as JIT compilers.
Ah yes, exactly.
Runtime performance is entirely unaffected by the use of macros. It can have a negative impact on compile-time performance though, if you overdo it.
While I can get behind most of the advice here, I don’t actually like the conditions array. The reason being that each condition function now needs additional conditions to make sure it doesn’t overlap with the other condition functions. This was much more elegantly handled by the else clauses, since adding another condition to the array has now become a puzzle to verify the conditions remain non-overlapping.
Issue resolved
For a little bit I thought this library might be a subtle joke, seeing the at the start. That combined with the compress() and decompress() not taking any arguments and not having a return value, I thought we were being played. Not to mention the library appears to be plain C rather than C++… surely the author should know the difference?
Then I saw how the interface actually works:
// interface for the library user, implement these in your program:
unsigned int SPR_in(); // Return next byte from input or value > 255 on EOF.
void SPR_out(unsigned char); // Output byte.
This seems extremely poorly thought out. Calling into global functions for input and output means that your library will be a pain to use in any program that has to (de)compress anything more than a single input.
Opinionated summary: Developers saw REST, picked the good parts and ignored the rest (no pun intended). They still called it REST, for lack of a better word, even though things like HATEOAS were overkill for most of the applications.
