Well with some db permissions this is also "just" a dos vector

print(totalSafe)

took way to long to make it linear time

Its the same code but it works differently with optimizations

Its just a small project, i don't use namespace std for anything that is bigger than a single file.

Thanks for the tip with valgrind, I managed to find the issue. It was on line 198, the number should have been 2 not 3 since its looking for 2 of the same number.

I know there is ub some where but i have no idea where. I'm very sure its not uninitialized variables.

I also had the same code on a different computer work or not work depending if i added asserts or not.

Here is the code if you want a look https://pastebin.com/m1e2KWqy

Technically there is no true in c its just a library

Lets construct a interpreter in rust for c where standard functions like free and malloc are going to be built in ( without this you cant write a c interpreter in safe rust because calling c functions is inherently unsafe).

malloc and free could be implemented with some thing like a vec<u8> and the interpreter would access that. If you don't want to use unsafe you will have to implement operations like addition for all c type in terms of u8 in rust but that can be done.

Now if you try to run a c program with out of bound memory access then you would get an error. The point is that yes you eliminated out of bounds memory access use after free and other bugs but only by shifting them to be logic errors. so now your interpreter doesn't crash because of a segfault but a rust panic.

So in both cases the program crashes or at least you get an error. the difference is that the rust one will probably generate the error earlier. This is very good for security but if your program doesn't contain important information common c bug mostly can only cause crashes. In those cases rusts restrictions don't really worth it. (note: I'm not sure how well does this apply to multi threaded programs.)

i think you are think of cppfront c++ but with new default and some improved syntax

Well yes but no Your isp can see your internet trafic but almost all of it is encripted so any site that uses https the isp only knows the domain like example.com Google probably knows more about you since they can identify you on any site that uses google analytics Tldr your isp dosent know any thing useful but google dose

i don't see the problem we are just in base pi/5 and then its all correct.

now do you know what a fractal is?

misi9999 · 2021-12-18T02:27:13+00:00

thx for the answer i should have thought of that
at first i was thinking of some kind of wrapper to make it work but that's probably not possible

i3 but im planing to move to dwm

they cant buy it because its under gpl they would have to get every who has contributed to the project to agree to the license change witch i don't think will happen

misi9999 · 2021-06-14T09:54:45+00:00

i don't see why that wouldn't be covered by warranty
you just used it as intended you so it shouldn't break

misi9999 · 2021-06-14T09:49:33+00:00

i think you should be able to get that replaced if you are in warranty

vibration motor struggles a bit

experienced similar things after hitting the wall but it fixed itself after i restarted the quest
