.... not bad, but not as crazy huge as it might look on first glance.
Funny how you just summed up why the US plunged the whole wolrd into a crisis.
18% return actually *is* crazy huge.
2% or 5% (or whatever your average inflation rate might be) would be "not bad".
JPEG encodes pixels by using a cosine transform on 8x8 pixel blocks. The most perceptually visible artifacts (and the artifacts most suceptible to cause troble to machine vision algorithms) appear on block boundaries.
Short answer:
a. 2D-FFT your image
b. Use the value of the 8-pixel period response in X and Y direction as your quality metric. The higher, the worse the quality.
a. Source (color) digital images use RGB colorspace (typically, the raw format is "RAW" with a Bayer layout). JPEG compresses three planes, with a YCrCb colorspace.
Due to colorspace conversion and quantization error, you lose information. That's called "lossy".
b. Even in lossless JPEG, each 64-pixel block is KR-transformed and quantized. Again, always lossy.
c. No free lunch.
Typically, even lossless JPEG makes you lose 1-2% of the total information (measured via image entropy). Things are slightly better with lossless JPEG2000. Both are *perceptually* lossless.
Side note, but anyways: in Europe, a law cannot be canceled by jurisprudence.
Short explanation: we don't have a "common law" based legal system but a legislative/codified system, as opposed to the US and UK.
Has anyone here even considered the possibility that the three kids were spoiled brats that desperately needed the education they didn't receive from their parents?
Like being punished for destroying others' stuff (including public stuff) ?
This story itself is possibly a flamebait, on the "damn stupid cops" motto.
This document (in french) confirms that it is not compulsory to even possess an ID card in France.
On the other hand, you do have to be able to prove your identity using some other ID (driver's licence, employee ID, even a local public transport ID).
OS X has Quicktime bundled, that is legal
XP has WMP bundled, that is illegal
Not exactly. OS X come with Quicktime, which is a library, and Quicktime Player, which is a media player. The same goes for Windows.
While it makes sense to bundle an OS with tech-enabling libraries, the issue is wether to bundle them with home-grown user level apps (e.g. media players).
wxWindows is, granted, easy to learn and has a OO model for widgets.
It's definitely not cross-platform, though. I'd say roughly 50% of its features work correctly (and similarly!) on both platforms -- I mean, GTK+ and Win32.
The Mac port is a horrible bunch of undocumented, buggy, incomplete crap. It even manages to be ugly (well, Qt also is ugly under MacOS).
Why don't people use Tk ? It's cross-platform too, and like Java, Tcl runs everywhere without recompiling. It doesn't even need to be compiled once!
Is it just because it's older (therefore less hip) than Qt and wxWindows ?

Exploit JPEG's weakness.
JPEG encodes pixels by using a cosine transform on 8x8 pixel blocks. The most perceptually visible artifacts (and the artifacts most suceptible to cause troble to machine vision algorithms) appear on block boundaries.
Short answer:
a. 2D-FFT your image
b. Use the value of the 8-pixel period response in X and Y direction as your quality metric. The higher, the worse the quality.
This is a crude 1st approximation but works.
Every single JPEG is lossy, for three reasons:
a. Source (color) digital images use RGB colorspace (typically, the raw format is "RAW" with a Bayer layout). JPEG compresses three planes, with a YCrCb colorspace.
Due to colorspace conversion and quantization error, you lose information. That's called "lossy".
b. Even in lossless JPEG, each 64-pixel block is KR-transformed and quantized. Again, always lossy.
c. No free lunch.
Typically, even lossless JPEG makes you lose 1-2% of the total information (measured via image entropy). Things are slightly better with lossless JPEG2000. Both are *perceptually* lossless.

A bit off-topic, but IMO, what's important is not who invented all the mentioned technologies. Leave that to the scientific community.
What's important is who was the first to mass-market the stuff.

I'd gladly go for a silver 'mini. My girlfriend seems to prefer the pink one, though... There's something here.
Sorry for the Apple proselytism, but you're wrong -- Keynote has more than decent PowerPoint import/export support. It is commercial, though.
