Flega categorizes Aprento (e-learning), Eurautomat (casino), Nascom(digital services), Lab101(interactive installations), Van In (publisher), and Ranavision (?) under 'Game developers' . These companies have different core activities. Cartamundi, Die Keure and Studio 100.. I'd say they're still publishers first and GDs second, no?

This does not mean that the list on Flega is useless of course. Just that the mere association does not as such represent a good list of video game companies in Flanders.

Thank you for your tip. I live in Belgium since few months and this is very useful !!! THX !

Re: Visual C++ 2010, why the hate?

I know this article is two years old, but I don't care. I've been developing in this language for going on five years. It's the worst. The syntax can be considered "random" in regards to most things.

The compiler error has regularly expected random errors, ranging from "mt.exe returning an error code of 31", "inconsistant metadata on expected types", and a few others where the only solution is to clean the solution and rebuild.

If you're looking to do Windows Forms development, you might as well just hang up your hat. The forms designer is what I'd consider broken. The designer just... dies. All the time, with no error messages.

When VS2010 came out, microsoft made it clear that they want the language to die when the stopped supporting intellisense. I was SHOCKED when they announced they'd be bringing some support back.

I know this is old, but thank you! I was pulling my hair out not getting this seemingly simple command to work, and this was the tip that saved the day :)

Add English to your browser's preferred languages list and .... you will get pages in Dutch
Then add French and .... you will get pages in English!
Move french to top, you get google.be in French.
There is surely some logic behind this :)

Re: Lua quiz

Key contains the string "123", you are right. There is nothing fancy with the metatable, it would have to be changed after the table gets created anyway.

Re: Lua quiz

Simon Jean-Francois — Fri, 22 Jul 2011 09:57:10 -0000

There are several ways for this to happen.
Most likely: the variable key hasn't been assigned the number 123 but the string "123" instead.
Less likely: the "get index" method of the metatable of t could be wrong.

Re: Restoring the executable bit

Implicit conditionals, awesome! Must... resist... temptation... to use it in my C code...

Re: Restoring the executable bit

Simon Jean-Francois — Thu, 07 Jul 2011 07:53:16 -0000

Excellent idea!
you can also save a few keystrokes with that version:
for f in * ; do [[ `file $f` == *executable* ]] && chmod a+x $f ; done

Re: C and C++ quiz

Drealmer — Tue, 14 Jun 2011 07:45:12 -0000

Perfect!

But I am not sure this is completely equivalent to sizeof( "hello" ), because I think C should return 6 for that.

Re: C and C++ quiz

Simon Jean-Francois — Tue, 14 Jun 2011 06:13:45 -0000

sizeof( 0, "hello" )
As the parenthesis for sizeof are not mandatory, this will should parse as sizeof ( (0,"hello") ), which is the same as sizeof("hello").
In C, this will return the allocation size for a "char *", which is 4 bytes on a 32bits machine or 8 for a 64bits system.
In C++, this will return the size of the "string"object, which should be 6 (h,e,l,l,o and nul-terminator).

gcc and g++ agree with me (I did not test other compilers).

Edit: sizeof parenthesis are only needed when taking the size of a type. So "sizeof 0", "sizeof i" are valid expressions and "sizeof int" isn't.

I like your quizzes!

Re: C quiz

Simon Jean-Francois — Thu, 09 Jun 2011 07:18:58 -0000

Two other ways for this to be true:
- x is declared as "volatile". The value of the variable changed between reading x and reading x the second time to evaluate x+1. e.g. Think of x as a memory-mapped register, which value could be incremented by one every-time you read it.
- (related). Multithreading! If a thread switch occurs in the middle of the comparison and the compiler does not "cache" the value of x, there is a possibility for x to have changed.

Perfect explanation, congratulations :)

"," is a comma operator: http://en.wikipedia.org/wik...
pi equals 14 in this case ;)

"," instead of "." :)

Yes true, but the WTF potential of C++ is so high it's not fun anymore :)

Re: C quiz

Ruslan Shestopalyuk — Tue, 07 Jun 2011 13:22:37 -0000

Would be a bit more interesting if it was a C++ riddle :)

class WTF{public: bool operator == (const WTF& rhs) { return true; } WTF operator + (int val) { return *this; }};int main(){ WTF x; if( x == ( x + 1 ) ) printf( "WTF\n" ); return 0;}

Yep, anything large enough that 1.0f has no effect on the mantissa, so #inf qualifies too...

But NaN won't work! Because any comparison involving NaN will be false, even equality with itself: http://www.parashift.com/c+...
