Out of everything the world needs, nothing is more urgent than the need for a new *chan. I'm going to take image boards in a new direction using a site (1channel USA.) I've spoke a little about this in #7chan. Right now I need beta testers. New accounts are going to cost $5 in the future, but in exchange for helping me start the site I'll give you a lifetime account for free. Just email me (team@1chan.us) feedback as you use the site to help the process of making improvements.

Main site: http://1chan.us
Beta registration: http://1chan.us/1chan.html

I havent written Perl in about a year, but I do love the language myself, perhaps later i'll dig up some old tools i built.

>gender has nothing to do with your skills, intellect or personality
I don't doubt you believe that, but you're probably wrong. It's somewhat agreed that both nature and nurture affect how we turn out. It's highly unlikely that all the differences (e.g. hormones) we have amount to nothing in the end.
Before attacking me: I'm not saying one is better than the other (I have neither the data nor the will to engage in that stressing, useless, debate), but that there are differences (some, like girls maturing before boys, are damn well documented).

girls who code?
I heard about one woman programmer - Augusta Ada King, Countess of Lovelace
Other womans( or girls, it doesn't matter) is a pathetic attempt to grow between your legs is what should not be, by imitation.
What can I say about people who are trying to increase "this fenomen"? - DO IT F*GG*TS && kill the programming in the world
sorry for my LOL_english ^_^

Your naivety is delicious, but your blindness makes me rage. There are a million of studies, that behavior is cause by a mix of nature and nurture.

You are basicly saying white people and black people are the same, but if you give the latter milk powder to eat, many will die in an unfortunate way. I doubt that is learned behavior.

Anyway if you treat boys and girls the same, one of them will start under performing, because they are wired differently. This has a direct effect on behavior.

Have a review: http://www.benthamscience.com/open/toanatj/articles/V002/37TOANATJ.pdf

It is a good starting point in these matters.

I wonder if anyone could shed some light on this (Picture Unrelated).
I'm new to this "split the class into a hpp and a cpp file" thing and still finding my feet with C++. Anyway, I'm not too sure why but the examples online all have something like this:

// myclass.hpp (pretend there are define guards)
class MyClass {
private:
int anInt;
public:
MyClass();
~MyClass();
void DoSomething(void);
}

//myclass.cpp
#include "myclass.hpp"

If what posted was a direct copy and paste, then it won't compile due to a few typos.

MyClass~MyClass() {}

should be

MyClass::~MyClass() {}

and you need a semicolon after the last bracket in the class declaration

class MyClass { 
private: 
  int anInt; 
public: 
  MyClass(); 
  ~MyClass(); 
  void DoSomething(void); 
};
 ^ right here 

I just tried it after making the changes and it works fine.

As far as WHY it works, I'm not really sure, it just does. I think the linker or compiler just takes care of that or something.

Wasn't a direct copy-paste, I just re-typed something made-up (with plenty typos it seems, lol). Anyway if it works for you, I'm guess maybe I have a linker error. At least I know where to start now with this problem, thanks. I'll install Dev-C++ and see what happens.

What do you mean by programmed? And what do you mean by telecommunications network?

Before specialized hardware (like a switch) is produced its requirements (fast, reliable) are already known and unlikely to change during it's life. Personal computers are expected to do everything - they must be programmable. Building specialized hardware for everything would be cost-prohibitive.

In other words: hardware is fast but can't adapt, software is adaptable but slow. You can't have your cake and eat it too.

Neckbearded Basement Dweller 13/03/29(Fri)19:29 No. 3550

I assume that by "programmable network" you mean a network whose topology can be changed without actual rewiring of the nodes. For such a thing you would first need to have all nodes physically connected to all other nodes, that way a virtual network of arbitrary topology could be placed on top.

Connecting all components of a processor (the adder, the multiplier, the control unit, etc.) is feasible because the computer is in a single location, not randomly distributed over the entire world.

Hello. I created this script for my database 4 months ago and now I need to make it look better. Basically I want to make the same thing but without so many case statements anyone know how this can be done?

SELECT *
FROM (SELECT A.TYPE,
CATEGORY = CASE WHEN TYPE = 'PCPA-NAL' AND LEVEL = 4 THEN '01-DOR LEVEL 4 EDITS'
WHEN TYPE = 'PCPA-NAL' AND LEVEL = 3 THEN '02-DOR LEVEL 3 EDITS'
WHEN TYPE = 'PCPA-NAL' AND LEVEL = 2 THEN '03-DOR LEVEL 2 EDITS'
WHEN TYPE = 'PCPA-NAL' AND LEVEL = 1 THEN '04-DOR LEVEL 1 EDITS'
WHEN TYPE = 'PCPA-HX' THEN '05-DOR CAPPING (HX)'
WHEN TYPE = 'PCPA-NHX' THEN '06-DOR CAPPING (NHX)'
WHEN TYPE = 'PCPA-SDF' THEN '07-DOR SALES EDITS'
WHEN TYPE = 'PCPA-NAP' THEN '08-DOR TPP EDITS'
WHEN TYPE = 'PCPA-RE-EDIT' THEN '09-PCPA RE EDITS'

That would be awesome. I am trying to do two things with this query, 1 make the code easier to read by either creating a lookup table for the many case statements and 2 on each department I want to exclude a specific code such as 90.

How can we do so much with software that we can't do with hardware, and, in the future, will the real hardcore amazing stuff be done with software people or hardware people?

Will software people still exist to work on a purely 'imaginative' landscape and be free to paint using an interface provided by hardware people?

Just wait until 3D printers can start printing new 3D printers. Add a bit of AI to that and shit can start to get interesting. Or apocalyptic...

Hey /pr/
I took a little course in java,really enjoyed it and decided to try and learn C++,any tips?

Neckbearded Basement Dweller 13/03/23(Sat)19:11 No. 3517

When you're thinking about C++, pretend you don't know Java. At its core Java was designed to appeal to C++ programmers tired of buffer overflows and invalid dereferences. If you try to apply what you about Java to C++ you'll only confuse yourself, since there are subtle but important differences, especially with regards to the semantics of object assignment and copy, and parameter passing.
