Alright so I have a function in C wherein I use a computed value numerous times. However, I do not want to define a variable to hold it and I don't want to compute it numerous times. What I want to do is use ebx/eax via inline assembly. How do I do it? I remember using this method in a driver I made a long ass time ago and it was something like __inline__asm ( "%eax": a) if I wanted to transfer eax to a. Anywho... help?

But the odds of the file's creator forcing that particular CRC (which isn't exactly hard) are somewhat higher.

If that's what you want, go write assembly. Don't try second-guessing your C compiler.

>Sadly I can't be arsed to debug and see if the compiler optimizes it as such and it doesn't recognize the register.
It optimizes it as such unless it recognizes that doing so is more expensive than the alternative. You know, exactly what you want.

Well fuck you then.
If you don't care to look at your programs instructions then why the fuck do you even care about performance that much?
Anyway, if you're using either GCC or Clang, I can guarantee you that it will optimize it into a register, and if it doesn't, there's probably a good reason for that.

In realistic browsers, it's gonna be damn hard to avoid this. There are some mutex implementations on the internet, but all the ones I have seen are only mostly correct and not fully correct; I tried implemented my own, but it was fiendishly tricky to get fully correct and I aborted the attempt when I realized I didn't need it for my project anyway.

According to the localstorage specification, the browser takes care of race conditions on its own and you don't ever have to worry about this. But most browser implementations don't actually do this for performance reasons, and sucks to be you if you want your localstorage usage to not break.

>>52367012
Probably, but this is a hobbyist project to be quite fair. I'll do it in python to get a hang of a more complex interpreter (35 opcodes) than the 21 opcode synacor challenge one, then I'll move onto the GameBoy interpreter which has like 76 opcodes IIRC and so many more intricacies

Trying to work around guessing correct resource lookup magic,
https://msdn.microsoft.com/en-GB/Library/windows/apps/hh965324.aspx

However the only way MS exposes it is through ResourceManager class which can not be manually instantiated.
So i figured i can obtain "current" class instance:

namespace wrl = ::Microsoft::WRL;
namespace foundation = ::ABI::Windows::Foundation;
namespace resources_core = ::ABI::Windows::ApplicationModel::Resources::Core;
wrl::ComPtr<resources_core::IResourceManagerStatics> p_statics;
{
wrl::Wrappers::HStringReference const class_id(RuntimeClass_Windows_ApplicationModel_Resources_Core_ResourceManager);
auto const hr(foundation::GetActivationFactory(class_id.Get(), &p_statics));
if(FAILED(hr))
{
return;
}
}
wrl::ComPtr<resources_core::IResourceManager> p_resource_manager;
{
auto const hr(p_statics->get_Current(&p_resource_manager));
if(FAILED(hr))
{
return;
}
}

But it crashes at get_Current since it is not a metro app and app-context stuff is never initialized.
Life is tough...

If you're going to paste a chunk of code and ask a question please use code tags or pastebin you fuck.

Semicolons at the end of statements are boilerplate. Separating same-line statements are ok, but having same-line statements anyway is anti-pattern.

Python pretty much does it best, as scope through indentation is a practice we all do even in languages with boilerplate { } ;

Languages should incorporate it for clearer code, the only use for the alternative is in autistic code golfing.

The file when talking about software has a number of issues.

Now there is the grouping by file type, that sense of course, you don't want your PNGs in your favourite language's source code

And directories are fine too, assuming your language makes use of directories for seperating units of code.

But just having one unit, translation unit or whatever it is called consist of multiple files for the sake of it shows a poor quality of tooling.

Really all you made with those files is a set of # tags like on a website for where to start reading the piece of code.

Having it all in seperate files leads to a lot of bookkeeping

Those are a whole different beast

But I always wind up with the same set of problems with multiple files that I do with a single file.

With multiple files the knobs you want to turn with the build system rarely actually match that set of files

You still have markup inside of the files to assist you

So I prefer to rig something super tiny on the spot, after all things change.

I guess this would be more of an issue with multiple authors but even then I don't see how you couldn't properly merge what is after all text

Stop pretending you don't like it fag

Working on my YouTube subscription manager.
The idea is to run the application every few hours. It'll check if the channel has uploaded one or more videos relative to the last run. If so, the user can send the result by mail or invoke a script. You can always invoke the script manually and it'll print the result to stdout.
I already can parse the config and open close the database connection.
I'm thinking about a name for my class that'll receive the result from the parsers and sends it to the user. I was thinking about 'Execer', short for executer. Any more suggestions?

>I was thinking about 'Execer', short for executer.

Don't do this or I'll slap you. Call it Executer.

I can't count the number of times people have dropped one or two letters from a word with columns and class names.

Unless you are dealing with AbstractFactoryAbstractFuckBeansController class names, you don't need to abbreviate words.

 int num = 0;
    for(num=1; num <= 100; num++){
        if(num % 3 == 0)                        // check if multiple of 3
            printf("Fizz (%d)\n", num);
        else if(num % 5 == 0)                   // check if multiple of 5
            printf("Buzz (%d)\n", num);
        else if(num % 3 == 0 && num % 5 == 0)   // check if multiple of 3 AND 5
            printf("FizzBuzz(%d)\n", num);
        else
            printf("%d \n", num);

alright fizzbuzz attempt? I would like to find a way not having to test for fizz & buzz twice but , I'm not sure how to do it the most economic way. Shouldn't a fizzbuzz program only have to do two checks per run through the loop? And use something like a goto to a specific print?

e = 1?:2;

sets `e` to `1` but everything else is obscure to me.

Empty ternary operators are not a part of C. They are a GNU extension.

This is a good goal, but here there is no way to do that. There are genuinely four cases here, and the 15-case is *almost but not quite* equivalent to a 3-case followed by a 5-case.

That's just a data access layer. You can really just call it your data source. If "sends it to the user" includes organizing it / making it pretty, you've merged View and Controller responsibilities from MVC.
