Depending on exactly what you mean by "gotten to grips with the basics", I'd suggest reading through [Dive Into Python][1] and typing/executing all the chapter code, then get something like [Programming Collective Intelligence][2] and working through it - you'll learn python quite well, not to mention some quite excell... |
I've used visual studio 6 and visual studio 2005 on the same system, so I know you can set it up so that both debuggers work. However, when I did it the setup just worked, so I can't tell you what I did to make it work, except that VS2005 was on the machine first. |

When I read thise quote I focus on the "*applications*" part rather than the "mission critical" part.

I have encountered the slow playing problem in your player, about 25% of the times I reloaded it, but only if another application using the audio device is running when the stream starts playing, as I reckon after a quick look.

It's simple, but have you checked endianness? It could easily be a mismatch between the endianness you have sent the data in and the endianness you are recieving in. |
I think in your case there is probably no reason to not pick Varchar. It gives you flexibility and as has been mentioned by a number of respondants, performance is such now that except in very specific circumstances us meer mortals (as opposed to Google DBA's) will not notice the difference.

The other answers are correct that headers are indeed encrypted, along with the body, when using SSL. But keep in mind that the URL, which can include query parameters, is **never** encrypted. So be careful to never put any sensitive information in URL query parameters. |
Very reasonable.
As an example, take a look at the aspnet_* services tables [here](http://msdn.microsoft.com/en-us/library/ms229862.aspx "table example").

The answer might very well depend on the compiler, so you probably want to edit your question (I mean, even the notion of segments is not mandated by ISO C nor ISO C++).

danivo, so long as the server's cert is capable of AES encryption, the level of encryption between the browser and the server is independent of the cert itself -- that level of encryption is negotiated between the browser and server. In other words, my understanding is that the cert doesn't specify the level of encryp... |

I don't believe there will be a collision. Using static at the file level (outside functions) marks the variable as local to the current compilation unit (file). It's never visible outside the current file so never has to have a name.

[ProcessExplorer][1] shows you all the DLLs that are currently loaded in a process at a particular moment. This gives you another angle on [Dependency Walker][2] which I believe does a static scan and can miss some DLLs that are dynamically loaded on demand.

Whether a file is downloaded or opened automatically is a browser, not a server, side setting.
The other way of doing it would be to change the MIME type for the file to something like application/octet-stream or similar to try and force your browser to download it. |
