c thread s: look like they should be workin and they compile but then i run it and it just pegs 1 cpu instead of many cpus

UPDATE: is now segfaulting when the thread is joined

UPDATE: everything is awful

just use Grand Central Dispatch aka libdispatch. easy multithreading for the majority of what people use threads for.

any actual progress is p definitely gonna require more serious refactoring though and gently caress that for now

heres the basic outline of your code if you would just stop being ridiculous and use c++11

code:


vector<future<result>> results;

for (some iterable that splits up work)
{
	results.push_back(async([=] { code for a particular thread to run; }));
}

for ( auto&& r : results) r.wait() // so i can make sure all of my tasks have completed

// do stuff with results

keep in mind if you're using std::async that the stdlibc++ version will always choose to execute in the same thread unless you actually give it the std::launch::async policy

use stackless python :getin:

but no really stackless python is hells of sweet, you run functions as tasklets and they perform work and you can "yield" or "imbalance" that tasklet at any time and it'll halt execution and move on to the next one

it don't seem like much but it's neat for game programming because you can have an AI's think() function just run in an infinite while true: loop and yield() after it's done thinking, or if it needs to think more you just dont yield and keep looping, and you can set some watchdog parameters that dont let a tasklet run for more than X instructions before forcing execution onto the next thread

so its a good way to say, like, some_result = watchdog.run( game_object.solve_path_to(some_point) )
and maybe that solve_path_to will just run for a while without making all your poo poo lag

EVE uses it to make their servers run less like poo poo

you should just use node then. does the same poo poo and is actually maintained, unlike python

hey guys i am thinging of writing a uefi-enabled x86_64 hobby os (NOT SEROIOUS!!).

what's a good free resource for os dev information? i need info on how to interface with the hardware.
i know that hal, acpi,... are things but i don't know how to begin to work on implementing them

i looked at osdev.org and it's full of outdated/wrong information and lovely alpha nerds.

help a brother out

PS: i am looking at the linux kernel and while it's very helpful it has a long history and i am kinda looking at the end result without any sense of context

the eve client is also written mostly in python (with all the low level rendering engine etc. written in c++ master race)

it's possible to run the entire client through a decompiler and modify it
people making all those mining bots just build upon the autopilot code and make their own ingame configuration UIs etc.

basically lol eve online

not trying to be snarky but what could a beginner sql book teach you that isn't already immediately intuitive

and anyway just use an ORM

i don't know, i guess that's kind of part of why i'm asking? i don't know what an ORM is but i guess i'll google it.

does anyone use a (osx) program to manage code snippets? i, terrible programmer, find myself wanting to reuse bits of code more and more these days. i've heard good things about Dash and Snippets, and i'e seen Codebox on the app store which looks alright. tell me the proest choice, yospos.

i use google docs and have a text file with code bits each under a heading that describes the code so i can generate a table of contents and easily jump to the one i want

going through projects to find things i want is getting cumbersome, there's got to be a better way!!!

searching throug snippets seems like it would be easy & convenient

that sounds p ghetto but the toc is a good idea
