Alas, Queensday is not what it used to be.
Ever since they (our fun-hating mayor Cohen and his cronies) closed down the
night market and nightly festivities, it has been on a downward slide..
The day-market has gotten way too commercial (read:lame) too.
And most of the day-street-parties have lame DJs imo, playing mostly house
music that's so monotonous that it's only nice to dance to if you completely
fill yourself up with drugs & alcohol.
Starting last year, boats are now severely limited in their audio-levels.
It's now no longer allowed "to hear the music from more than 10 meters from
the boat". Another set of nails in the coffin.
IMO, it's the neo-kak of Amsterdam that's causing this. Those nice old big
houses on the canals, they're these days owned mostly by those not raised in
Amsterdam. People from the richer villages and towns have moved in.. I read
a report in the paper about how those rich turds have complained to the city
council about the loudness and "disturbances" of Queensday..
I'll admit that on queensday with fine weather the "vrij markt" (garage
sales by 20k+ citizens in downtown alone) you can still pick up some cool
art & items cheaply. And all the kids doing the garage-sale thing with their
leftover toys are cute too of course. But that's about what's left of the
entire "old" Queensday.
I'm genuinely sorry to be the one to break the bubble about this once very
cool party..
But i recommend anyone buying a planeticket and hotelroom for it to find a
new party scene.
Queensday ain't worth the money anymore imo..

Hello PHPers,
I've learned that php doesn't support multiple inheritance, b/c if you
need multiple inheritance usually it is a sign you've got a design
imperfection...or so they say.
Well, I'm using a framework (Codeigniter), and i'm extending the core
libraries. The trouble is, I want to also extend a second custom class,
and I don't want to change the core codeigniter class definitions as
this makes for awkward upgrades.
I read about mixins - no thank you. i do not want to even think about
mixins as it looks like it would be the source of all debug hell...
What's a programmer to do? Is the only option i am really left with to
duplicate the code in each class?
Thanks,
dK

I just found this in the archive:
http://old.nabble.com/Multiple-Inheritance-td15717829.html
That example Nathan provides of mixin is a lot cleaner than a different
example (from a different poster on a different site) i was looking at.
I could probably use the method Nathan proposed in a pretty clean way.
i'm justified for using this multiple inheritance workaround to keep the
core framework untouched?
Does anyone else have a different approach or suggestion?
Thanks,
dK

If the original author of one or both libraries did their job right, they'll
have provided an interface as well as the class that implements it. Then you
can implement the interface and pass through to a new instance using
composition.
To wit:
interface AInterface {
public function doA();
}
interface BInterface {
public function doB();
}
class A implements AInterface {
public function doA() { ... }
}
class B implements BInterface {
public function doB() { ... }
}
class YourClass extends A implements BInterface {
protected $b;
public function __construct() {
$this->b = new B();
}
public function doB() {
return $this->b->doB();
}
}
(It would probably be a little more complicated in a real use case, but
hopefully that should get you the idea.)
Mind you, that presumes that the code you're dealing with provides interfaces
and when doing type checking checks against the interfaces rather than the
classes themselves. If they don't, you should file a bug against that base
library as They're Doing It Wrong(tm).

Very likely your modem is buffering the uploaded data.

That is exactly what I do with the PHP upload progress extension and a
special plug-in for the Forms Generation and Validition class. There is
no need for Flash.

Here is a live example:
