How did Japan manage to preserve their gene pool while Brits all look like 10 generations of inbreeding?

>>57145603
>Pajeet overflow

>>57145603
Does it even matter in the end? They would have been better off not preserving it since they all look like genetic failures.

>>57145620

hey, I just found a good pejorative term for stackoverflow.com

>>57145579
Incorrect. Japab looks at university on a national scale, theres no reason for competing against schoolmates except for healthy empty rivalry. Japan has WAY more social activities at school, and clubs are glorified.
I don't think japan is better though, companies are way too invasive and the culture doesn't support individualistic behavior. Comparatively you'd be right on with china, that place is truly cold, the huge focus on family and deifying parents means that each person is his own tribe and that screwing over others is a virtue

Making a website, just wanted to know what everyone else is using. I have a fair ammount of skill in jurry rigging, but most of what I know about web dev software is a decade out of date. What software do people use these days to make it go faster? main feature I'm looking for is possible auto complete and debugging features. real time preview would be a bonus but far from needed. What do you fags use?

Anyone can help me on a multithreaded epoll server?

>>57145697
No.

hitler did nothing wrong

>>57145579
in a way that's the point.
4chanX filters images based on MD5 hashes, so does that mean that if I filter a specific pepe and someone takes it, changes obe pixel and posts it again, does that mean that the manipulated pepe will bypass the filter?
That's kinda the point of the neural network which would determinen if it's a frog or not, and feed the large database.
It's basically the only way if you want 4chanX filtering.
I imagine anything else would be too performance demanding

are there any sites of similar quality as Codeacademy for learning stuff?

ten hours of interactive tutorials are equivalent to literal months of learning by scrapping information together

>>57145721

>>57145709

>>57145711

Mods delete large swaths of posts on /dpt/ whenever it gets too political, because it's "off topic", and sometimes will even delete the entire thread for it. I'd like to prevent that situation from happening. Since the old thread is dead, I think we should not bring existing political discussions into the new threads to avoid them being deleted.

Way too complicated.
What you want is a simple, fast similarity check.
Just convert that image to gray scale and scale it down to like 32x32 or something.
Then you compare that byte for byte (maybe allow for a tiny window here).

I'll train a neural network if you make a torrent of at least 1k pepe images.

Why would it be a muiltthreaded? I thought tht whole point of epoll was to avoid threads and use a single threaded event based model. Just like NodeJS in a sense.

>>57145953
We are going to the hills. A is a vector of n heights (integers) on our way. We want to place as many flags on the hilltops on our way as possible. A hilltop is a place A[i] in which A[i-1] and A[i+1] are smaller than A[i]. The only restriction is the distance between the flags has to be greater or equal than the number of the flags placed.
Assume the first and the last heights in vector A aren't hilltops.

Yes but it's still possible to achieve greater performances by spawning one thread per core. The fact NodeJS doesn't do this is due to laziness and, Javascript.

>>57146393
Can you explain more about it? I don't understand it very well actually. Tried to check the kernel source but it didn't help

>>57146365
Why do you need edge-triggered for multi threading?
Do the docs say level-triggered doesn't work with threads?
Or does the level-triggered behavior not work for you?

>>57146387
I started off writing it in plain C, but couldn't be arsed making my own map to store the connections rather than using the STL one..

>>57146409
>2016

>>57146416
For performance reason. It works fine level-triggered but then I have to check for each events if they're already being processed by another thread, unless I'm doing something stupid.

>>57146473
I might be tempted just to have the separate threads handle different sets of connections, and just add new connections to whichever thread:epoll set had the least at that time.

I just read a couple short chapters on C (coming from C++).
I also found out something I never knew:

for(;;){
//do shit
}

is valid

I always thought you had to do like while(true) or while(1).
I didn't know you could do that with a for() loop at all...
Now, here's my question: is there any particular reason TO use a for() loop like that instead of while(true) or while(1)?

Additionally, since my interest in C is mostly Operating Systems, how easy or difficult would it be to start a kernel from scratch that I can dump into a VM?
Just like a side project atm.

How difficult would it be to write a bootable kernel (that maybe says, i don't know, fucking "Hello World")?
Furthermore, how difficult would it be to make it turn off?

There's a formally verified compiler available for c. Not for c++. There's a verification annotation language (acsl) for C. Again, I'm not aware of one for C++.

So that's an argument if you're targeting high reliability for your projects.

I've got a bit of a problem /g/, and I was wondering if you could help.

I'm writing a textboard using Flask (which uses the Jinja templating engine).

If I wanted to display all the threads, I could just query the db and pass the result dictionary from the controller to the view and do something like:

    {% for thread in threads %}
        display thread here
    {% endfor %}

The problem I'm having is: how the fuck would I display the last couple of posts to a thread (like pic related).

Any ideas how I'd do something like this?

>>57147847
use sorting and LIMIT in SQL?

>>57147847
Since you're probably using SQLAlchemy you can setup a relationship then limit the queried children to only last few (or first, not sure what you want) then extend the thread rendering method to include those if the children member is set and contains any results.

(where does the t. meme come from anyway?)

>>57147868
It's not a question of how I get the data, I know exactly the queries I'd need to do.

It's how I somehow get the two query result dictionaries (threads and thread replies) and render them together.

>>57147907
You know how to get the data and you know how to display it.
I don't understand your problem.

Is there any good/simple/open-source game like teeworld? I'm bored.

>>57147892
It comes from Finnish chans, where "t." is short for their equivalent of "sincerely" or "best regards" from what I remember.

This isn't so much a dependency on frameworks (Flask is a micro-framework, it's a large reason why I'm using it), it's just how unfamiliar I am with creating views with Jinja.

cout << "Would you like flight 3, 4, or 5? ";
                int flightChoice;
                cin >> flightChoice;
                    switch (flightChoice) {
                                         case 1: 
                                                 cout << "You didn't choose a valid flight. Choose again: " 
                                                cin >>flightChoice;
                    case 3: 
                        cout << "You chose flight Three" << endl;
                                               FlightThree++; 
                        break; 
                    case 4: 
                        cout << "You chose flight Four." << endl;
                                                  FlightFour++
                        break; 
                    case 5: 
                        cout << "You chose flight Five." << endl;
                                          FlightFive++
                        break;  
                                        default: 
                                             cout << "flight not available. Choose another: "; 
                                            cin >>flightchoice; 

                    }

I'm trying to make a program where a user picks which flight to go to and if they choose flight one I want it to say that the flight is not valid and have them pick another flight. It seems to let me pick another, but it won't register it when there is a summary at the end when it's suppose to state which flight the user picked.

what is the most and the least "elegant" general purpose programming language?

imo,
most: ruby
least: c++

>>57148059

For case 1: it's suppose to say

"Flight One is not available" 

>>57148060
>c++
>not elegant
hmm

>>57148060
What a stupid question. "elegant" is about as subjective as it gets.
That being said, it's Haskell of course.

>>57147892
>>57147912
>>57147944
It came from Yililuta (probably the only Finnish chan, recently deceased) and was later exported to Krautchan. The simplest translation is "regards" and a common usage was usually

"t. knower"

as in, "regards, one who knows all about [subject]", generally for menial subjects. Once it made its way here, it developed other usage like "t. pajeet" or >>57147912 's "t. meme expert" - it's not meant to be overused and it's not meant for complex titles

>>57148060
Most is Lisp.
Least is Perl.

>>57148060
Most: Haskell
Least: PHP

>>57148060
Scheme wins in elegance. Only has a single structural primitive: The cons cell.

C++ varies a lot. The template code syntax is a pain, but RAII is quite a neat pattern for what it does..

>>57148060
most elegant: C, ASM, Haskell
least: Everything else

Eh. I don't have a powerful PC anyway. Only 2 cores, 2 GB of ram. It's under 60% workload right now. I shouldn't expect too much difference. I was hoping it would be less, though

>>57148059
Because you modify the variable you are switching on.
It would have to execute the switch again.
The switch is a one-of decision, it decides which case to run and does so *once*.
It's not like a cascade of ifs.

Guess it'd have to be on the stack. Thread local storage wasn't implemented until the itanium abi, and exceptions are thread-local.

>>57148171

So would I have to create another switch statement within that case?

 
case 1: 
 cout << "flight 1 not available. Choose another: "; 
cin >> flightChoice; 
switch (flightChoice){
case 3: 
break;

}
break; 

Guys I have a question
I use Transimssion-qt on Windows 7 for torrenting.
There is an option in prefferences to execute a script when torrent finishes.
I made a simple script:
@echo off
taskkill transmission-qt.exe
I chose to execute it.
The script works on its own when I double click it, a command prompt pops up for 0.1 sec and Transmission shuts down.
BUT
When a torrent ends, the cmd pops up but Transmission doesn't shut down and just keeps on going.
What gives?

>>57147651
>>57147665

Whoa, whoa, somebody remembers my shitty "proof"..

>>57148438
And what do you do when the user picks 1 again? Another switch?

What you need is a loop around your switch. While the user hasn't picked a valid option, keep asking them.

>>57148438
You could use nested switches.
But something more disciplined like finite state automata (look it up) is better.

i've just never heard of a programming and analysis degree, and idk if most employers will have heard of it either. if they have a lot of the same requirements you could try to double major. programming and analysis sounds like more of the stuff i enjoy about computer science. ie more theory and less discussion of UML diagrams and boring shit like design processes

I'm trying to get into OpenGL, but there's a part I don't understand.

Element array buffers are used to store as few vertex data as possible. So if I have a cube, I only need 8 vertices for each corner, and the element array tells how to connect those to create all the triangles.

But how can I apply this to textures?

The tutorials I have found so far abandon using element arrays at this point, and just describe the cube with as much vertices as needed, and they apply the corresponding texture point to each point. Why is that? How could I handle texture data while setting up the least amount of vertices?

>>57149088
Awesome.

When doing 0-padding for converting hex to base64, Wikipedia translates an index of 000000 to =, why do that instead of translating it to A?

Should the implementation care whether or not an index of 0 was generated through padding or occurred naturally in the input?
