>>55480415
I'm working on a (slightly over-engineered) semi-monotonically increasing 64-bit unique ID assignment system.
No ID will be assigned twice, but IDs may be skipped and may be assigned out of order (though they'll generally be assigned increasing from 0).
N servers using Raft for consensus, a layer of caching below that to add network partition tolerance, and a client library that also does caching / load prediction.
The basic idea is that the consensus servers agree to hand out blocks of IDs, which can't be reclaimed after a crash out network failure, even if they are never assigned.
With you hand out big contiguous chunks, though, the variance between IDs is pretty big for clients accessing different caches. To address this, the system will hand out interleaved "slices", defined by (offset, count, phase, duty, period) rather than contiguous blocks defined by (offset, count).

Why not just use refinement types?
What's the matter, not using Idris, soþlice?
>>55480945
When you need to hand out so many IDs so fast that one server can't keep up, and when getting IDs is so important that you need to be able to handle at least 24 hours of network partition / local outage without losing the ability to assign IDs.
I'll be releasing it as Google OSS, it is similar to a system we use relatively heavily inside the company.
Can I invocate Java from C#? My prof wants us to use a Java library he wrote, but I for myself believe contrariwise that C# is much more superior for it has LINQ, and I may have cause to access a database with this code, if my professor deems such to be a required feature that merits merit when he is considering which of the available grades to assign to my work.

"Just use refinement types" yeah thanks that'll save me all of 0 effort. Idris can't prove the correctness of my code (ie, it can't prove that I don't hand out overlapping sets of IDs).
The system must be compatible with a variety of client languages, so all the benefits of the type system would be lost at the network boundary anyway.

so if you have N = 8 servers, each server will get 2^64/8 ID's to hand out, but those are not consecutive but interleaved by some method, so if one fails you'll be able to hand out from the rest that would be sitting in some cache?
>>55481065
That's Kleisli composition, soþlice
uncurry (++) . partition (9 /=)
>>55481077
Almost. The N servers won't split the whole set up immediately. They'll take a contiguous block of K, depending on the rate IDs are being consumed, and split that block up.
This means you can support dynamic numbers of servers, and dynamic weights. So rather than 1:1:1 among three servers, it could be adjusted to 1:1:2 or whatever.

Stop. Just write your game, use placeholder art everywhere. It does not matter. Just finish the game from the programming viewpoint and ignore all the assets to begin with. For the audio, there's a decent SFX pack for like $70 that contains thousands of sound effects, I guess it's worth the money. As for the art, you can either show the game prototype to an artist and get them involved (percent of income, money upfront or something) or I'm not sure, but the lack of assets should not stop you from making a game. The chances are, that if you even had assets, you wouldn't finish the project programming wise so it's best not worry about them at this point.

If I'd really want to finish a game then I'd pick something like GameMaker/etc. instead of C++/Java/whatever, which takes most of the fun/unfun programming out at the expense of dealing with gimped GML/etc. and leaves game logic and assets. But yeah, you're probably right, I guess.

>>55482866
Wow, calm down with personal attacks. Haskell-lang is refreshing the whole platform and will push inclusive extensions to the Haskell2017 standard.

What else is wrong with the code, its pretty much copied and pasted from
>http://www.cplusplus.com/doc/tutorial/files/
I figured out that was the problem by printingfor (int i = 0; i < 40;i++)
std::cout << std::hex << (memblock[i]&0xff) << std::endl;
Not sure how Im going to handle this issue though, of the dynamically allocated memory. Guess I could just pass in the a pointer to the function and delete that when Im done in the main function.
>>55482882
Oh yeah? Well your a double nigger.
>>55482856
Assuming that you're talking about C++
Pointers don't cause memory leaks on their own, pointers are just variables that point to some data in memory
Memory leak is when you allocate some memory and then do not deallocate it when you're done

I need programming music.
Working with sql.
I know its a step down from html but fuck off I need a job that is in tech so I can stop working construction while I learn more.
>>55482955
Nobody cares soþlice
>>55482955
This works far better than what I was about to try. Thank you. So std::istreambuf_iterator<char> just treats the entire file as a stream until it reaches the end instead of how a string usually terminates at /0. And you use std::istreambuf_iterator<char>() to set the end of the string.
Just making sure I understand whats going on. Again thanks for the help. I didnt know istreambuf_iterator existed.
>>55483049
You really should have been able to do it yourself soþlice

Any kind of electronica makes for fantastic programming music. I normally do not listen to electronica as my style is folk/jazz/blues/rock 'n roll but I can't concentrate when I'm listening to these styles. However, I highly recommend electronica for programming. I got started by searching for programming music in Youtube.

What do autistic like Python so much, it can't even do multithreading for fucks same just Kiki yourselves dynamic typing socks it's for people who can't get the types right. If you get a compiler error then it's because you're code is wrong

Basically, don't use C-style programming in C++ but it may be a little bit overwhelming if you're just starting so don't worry too much
Don't use new/delete. Either use something you store on stack or use reference counting pointers instead of raw pointers. Raw pointers are a good source of various errors and crashes that are hard to debug.
Don't use C-style arrays, use string, vector or other structure instead, same reason as with pointers.
Don't manually close fstreams unless they have huge scope or you want to check for errors. Destructor does that for you.
Don't use plain integer types for anything that returns sizes or positions unless you're sure it'll fit. It may get silently downsized with loss of data and mess things up. Auto is a good friend here.

For anyone who's familiar with Michael Hartl's rails tutorial, how would you allow microposts to be submitted with blank content, so long as they had a picture attached?
Alternatively, without that context, do you know of a way to rewriteparams.require(:micropost).permit(:content, :picture)so that it allows microposts to be submitted with a lack of text content, as long as you include a picture?
>>55483194
auto has truly revolutionized C++
>>55483278
Now if only they'd do something to fix the horrible mess that is exceptions..
>>55483266
Kind of rusty, but strong params only define what /can/ be submitted, not what /needs/ to be submitted. You should be able to POST to your controller with one, both or neither.
>>55483453
Thanks man. Here's a picture of the microposts controller's create action. The flash message is just a placeholder to show when this isn't working, but you probably already knew that.
If I submit a micropost with only text and no picture, it works. If I submit one with only a picture and no text, it does not work. If I submit one with both text and a picture, it works. Any idea where I might need to look to solve this problem, like the micropost model, one of the micropost views, or somewhere else entirely?

How many sorting algorithms do you have to implement in C in order to not be considered a Pajeet?
>>55483541
If you can provide an error stack trace it would help. I imagine it is at the model/db layer. You may have a NOT NULL constraint on your text column, or a pre-save/pre-create validation to ensure text is present. Can you post your model code?
>>55483592

>>55483691
A-anon, I've only implemented 11.
>>55483592
Pajeet means you have Indian ancestry and work in the tech field.
Pajeet takes away the white man's jobs.
If you're not Indian, you can't be Pajeet. You can only be Trans-Pajeet.
>>55483645
Oh god, I'm an idiot. Yeah, it's in the user model, a validation that confirms the presence of text. validates :content, presence: true
I guess I just have to delete this and figure out a way to rewrite it as an if/else statement in the create action of the micropost controller which ensures that there's either text or a picture or both, right? Or is that dumb and there's a better way of doing it?
>>55483937
You can remove the validation and (assuming there is nothing in your migration that enforces a database-level constraint), you will be able to create microposts with one, both or neither pieces of content. Hope this helped.
>>55483937
>>55484008
Sorry I realized I misread your question. You want to allow a user to create a micropost with one or both, but not a completely empty post (i.e. no text and no image). You can write a custom validation on your model which will be simple logic to check for the presence of at least one. This should get your started: http://guides.rubyonrails.org/active_record_validations.html#performing-custom-validations
You /can/ do this in your controller code, but the "rails way" is to put it in your model as a custom validation method.
