PNG is basically a zipped bitmap. a handful of filters are done across the pixels down or sideways. each filtered scanline is zipped (the filter type is stored per scanline so you can use the opposite filter when unzipping)
the filters are just designed to make the data more compressable to zlib.. a perfect gradient from black to white will compress very well with the difference filter. the best filter depends on the image and the only way to find out is to filter it and see how well it compresses.. this makes compressing to PNG veerry slow, most programs won't try every possible filter or even worse just always use the same filter. compression performance depends on how much cpu time you put into analyzing the image.
anyways.. what you said about wavelets is a good idea. they could be used as a preprocess in conjunction with a new png filter type to make a very small png's.. they would be lossless copies of the lossy master.
PGP (pretty good protection).. for second I thought you were talking about GPGP (gordon's pretty good protection), a proprietary scheme I developed for one of our apps
Maybe you are wanting to mark my post as flamebait because of the Microsoft reference appears to be a general Microsoft bashing fest... It was merely a colloquial reference of modular stripped down linux vs Monolithic all inter-twined Windows.
actually you've got that backwards.. windows utilizes a microkernel architecture where as linux has mucho crapo built into the kernel. much more to break, it's just well built. also, I know it depends on the distro.. but you can't say windows comes with more crap out of the box. your average linux distro is 1gb+ out of the box, way more than windows comes with. I tend to think of that as a good thing though
myself and every other developer I know it's common to build up an arsenal of code (written or otherwise collected/customized) for various things. more importantly there's the problems and how you solved them that you'll never forget but the problem may come up frequently regardless of where you work.
it's pretty rare that you find code that you can copy paste and compile. usually you need to read the code to understand the algorithm, then rewrite it to suite your application/variable names/coding style.
one-off hacks and throw away code probably all looks the same company to company programmer to programmer. it's the overall system design and high level architecture that I would consider the meat of the IP anyways.. and it would typically take more than a single developer to pickup and rebuild it somewhere else
I'm all for throwing more resources into spaceflight, but having many small teams keeping secrets from eachother doesn't sound like a big improvement on having a few large teams that work together.
You don't know much about engineering do you? The more people that work together, the less likely it is that anything gets accomplished. Read up on competitive learning, competition in general and its role in society. Then think about where we would be today if nobody had a competitive spirit and just shared secrets with eachother.
Microsoft is an inevitability, just like Neo. Asking what the world be like without microsoft is like asking what the world would be like if WWII never happened.
To answer the question, the world would be exactly the same.. except the software company holding a monopoly on operating systems wouldn't be called "microsoft" it would be called g-soft.. and today you would be asking the question "what would the world be like without g-soft?"
a better question would be why is the microsoft-anomoly inevitable.. that one, I think, is because anything that makes up an integral part of our infrastructure (such as an OS) that isn't yet mandated by government will naturally fall into a monopoly simply because it's convenient.
Just because 50 million people decide that what they're doing is right and justifiable doesn't mean that they're right and justified.
and what do you think determines right and wrong.. god? a billion people don't have a moral dilema stealing music, why? maybe its because deep down we KNOW that $3million/year is TOO MUCH fucking money for a 17yr old girl no matter how hot she is and no matter how good she sings.
The original client/server scheme--where the application's visual presentation and business logic reside on the desktop, and data resides on a server--is an idea whose time has passed. It's being replaced by Web browser clients, n-tier systems and Web services.
this couldn't be farther from reality. web clients are dying, making way to desktop clients that communicate to the server via webservices. in short: old tcp/clients out, web clients in, web clients out, new xml/rpc clients in
how about just AreaOfCircle.. your ide should tell you that its private and that its a float, and "computed" is sort've implied by it being a variable in the first place. In the case this is a class property where the class is the circle well then it should just be Area because circle is implied.
I'm really picky about variable names.. in the end if you can stay consistent and make good decisions on variable names it ultimately makes the biggest difference as to the readability of your code

uhh.. whats another popular detergent?
thats like asking whats a popular operating system? answer after reading this list:
- shit
- puke
- warts
- hookers
did you say windows? ha! I primed you
when you get into more advanced filtering methods, adding artificial noise (from a variety of noise "types") can help filter for various anomolies.
if(x = 1)...
still not even a compiler warning.. *sigh*
curious, of what serious error do you speak?

if you replace "they" with "we"
you get what you pay for.
