*YOU* are full of bullshit. C++ is a horrible language. It's made more horrible by the fact that a lot of substandard programmers use it, to the point where it's much much easier to generate total and utter crap with it.

So I have a document at a given URL, say "http://example.com/doc". It's a big document, and clients need a consistent synchronised replica of this document. The problem is that this document changes frequently, but only in small ways. It make sense that a client will have to grab a copy of the whole document initially, but do they really need to grab the whole document over and over as it changes? What options exist? Is "Delta Encoding in HTTP" the right answer, or is something else needed?Read more...

f you install Ubuntu from the live cd or alternate install cd, the 'generic' kernel would be installed by default. The 'generic' kernel focuses on i586 and i686 CPU architectures. But if you have a newer CPU, like Pentium 4 HT, Dual Core or Core2Duo, you might want to install the 'server' kernel to improve your PC performance. The 'server' kernel focuses on i686 architectures and posses some unique advantages over 'generic' kernel in case of task management. Here is the steps to switch to server kernel.Read more...
