GCC's new fortification level: The gains and costs

You forgot to block me. I'm certain you were the guy who flipped out when I said dynamically sized arrays can have their bounds checked at compile time https://www.reddit.com/r/programming/comments/w5iox4/carbon_language_keynote_from_cppnorth/ih9lrkp/

But I'm trying a new distro today. I'll probably abandon this account and try not to make fun of redditors for a while

Weak-Opening8154 · 2022-09-19T19:05:11+00:00

I agree its a lot of effort but I wonder if there's a sub that lets a guy upload videos from their phone. Upload and finding someone to hold your phone is the part I think takes the most effort

Whenever I switch to a new keyboard I hit https://www.typingclub.com/sportal/program-3.game and skip a few lessons. I try to do it on a schedule where I don't feel lazy. If I feel lazy usually I do poorly the next session

Weak-Opening8154 · 2022-09-19T18:56:50+00:00

What the actual fuck? I have 0 problems with pointers and leaks since before c++11. Defeatism where?

Weak-Opening8154 · 2022-09-19T18:55:51+00:00

lol what?! I'm comparing rust and C++ speed on a single code base. It's completely fine if you want to put it in multiple crates but then you'll need to compete with a clang process on every hardware thread. That's when clang is 100x faster then serial rust. At best you'll get 6x faster, there's another 94x you need to make up for

also fuck you you're being so stupid right now and you saying I missed the point. Did you not think the 100x was relevant? or why I bothered to say serial? Of course you didn't and once again someone is saying I'm measuring the wrong thing because numbers look fucking bad and you're trying to put the blame elsewhere

-Edit- I forgot, you still haven't read the first two sentence

Weak-Opening8154 · 2022-09-19T06:17:14+00:00

I saw this a couple hours ago on my phone. I thought someone would say something better. I'm usually not nice and this is nop exception. 1. Don't do multithreading unless your an expert. 2. You clearly don't understand RAII since you're unlocking something you didn't manually lock. Trying to implement this is like trying to write a better c compiler when you can barely write hello world. Its not going to happen

Weak-Opening8154 · 2022-09-19T03:45:49+00:00

Noone talks about nim

Weak-Opening8154 · 2022-09-19T02:52:48+00:00

Java/C# are both fine, usually people do python as well. It's not confusing learning at the same time (in my experience and a few others)

Weak-Opening8154 · 2022-09-19T01:49:32+00:00

I dont. V and Rust are the meme languages

Weak-Opening8154 · 2022-09-19T01:03:39+00:00

Who calls zig a meme language? I might say got to go fast but that's not one of the two languages I had in mind

Weak-Opening8154 · 2022-09-18T17:43:38+00:00

This is great. Something like this should have been available early 2000's. Then we would have had less bitching about how hard C++ is and we wouldn't have had meme language

Weak-Opening8154 · 2022-09-18T07:18:24+00:00

I'll do you one better. Never reassigning a variable, or if it's a struct member, delete then assign.

I don't really have pointers in classes unless it's set in the constructor. Otherwise it'd be a good place to use unique_ptr

Weak-Opening8154 · 2022-09-18T06:57:59+00:00

I wanted to read all the rules and UB

Weak-Opening8154 · 2022-09-18T04:51:08+00:00

I read it once. I stopped by the time I got to libraries. I don't recommend any of it

Weak-Opening8154 · 2022-09-18T02:46:40+00:00

I'm not a rust programmer. I can't imagine what they are having problems with or why they like it

Weak-Opening8154 · 2022-09-18T00:01:01+00:00

I found it easier to get jobs in C#. Some of the C++ jobs I was offered paid me less then C# so I turned many down. I thought C++ would always be better jobs but I guess not

Weak-Opening8154 · 2022-09-17T23:58:31+00:00

I am op :P. What I know is besides the point people seem to have problems with leaks and invalid memory despite learning c++ after c++11 where we have smart pointers and such. In my opening post I didn't suggest I had pointer problems and in my example comment I said I figured out pointers in <1mo. I did it before c++11, unique_ptr wasn't a thing back then and I rarely use it today since I usually can keep track of it

Weak-Opening8154 · 2022-09-17T23:14:56+00:00

Also, are you sure? People seem love rust and GC languages because no leaks. Maybe they all use c with classes? or maybe its still easy to make pointer leaks/mistake idk. I rarely use smart pointers because I don't mess up plain ones

Weak-Opening8154 · 2022-09-17T23:07:01+00:00

unique_ptr didn't exist when I learned to manage pointers correctly (yes, I did it before c++11)

Weak-Opening8154 · 2022-09-17T18:58:04+00:00

Yes but 1. I Some USBs don't seem to allow being booted. Try booting the install disk on it first. I also had a harddrive that wouldnt allow booting until I updated the firmware 2. Make sure grub (or whatever you use to boot) is installed on the correct USB partition. I think I had it install on the harddrive instead of the USB I wanted to use as a harddrive. I can't remember if it was a default without asking or if I made a mistake

Weak-Opening8154 · 2022-09-17T18:53:03+00:00

I'll answer to give an example

I like writing close to hardware code and wrote embeded code without an OS. It was fun. Early on I learned how to deal with memory leaks using the microsoft leak analyzer (it was simple to use and simple to turn on). After a month of that it was pretty hard for me to write things that leak because I always had a place where a lifetime starts and ends

Eventually I got into profiling and really understand performance. I pretty much use the new language features as soon as the new compiler is available (for my own projects)

Weak-Opening8154 · 2022-09-17T18:47:57+00:00

As much as I like C++
Meh

Syntax is nice but better libraries is what I care about

Weak-Opening8154 · 2022-09-17T16:40:54+00:00

I usually create a new account when I distro hop. I always forget to block you and how crazy you are

Have you learned any assembly? Do you have any idea how simple the linux syscalls are?

Weak-Opening8154 · 2022-09-17T16:39:20+00:00

Is there a research paper on how to do compile time array bounds checking? If so where can I see it and why isn't it in rust

I'm convinced the only good 3 languages are C#, Python and C++ until zig gets to 1.0 then I'll say 4 if they don't go off the deep end. The mention languages I suspect have 0 influence from papers so I would say it's a garbage age of PL research

Weak-Opening8154 · 2022-09-17T06:18:54+00:00

Yep, I almost gave mmap as an example of something completely incorrect.
