• Example open source client-server code projects

  - by Ricket

  I'm still trying to determine an answer to my question from a few minutes ago, "Should client-server code be written in one 'project' or two?" and I think it would benefit me to see how other projects organize their code (and hopefully deduce the pros and cons of why they chose to do it that way). What are some open source client-server projects which might be best to look at and mimic their code organization style? Java is preferred but not required.

• Customizing the look of S3 expiring urls

  - by Gregoriy

  Creating expiring links for Amazon S3 buckets, could I somehow change the name of AWSAccessKeyId to something else (to custom it, to speak so) so that not to disclose the use of Amazon in my web applications? For now, it looks like so: http://video.mysite.com/T154456.flv?AWSAccessKeyId=1ESOMESPECIALIDJJAKJ6RA82&Expires=1241372284&Signature=ddfr%2BlkoSEPAL%2BGbMwlMzj6q%2BCY%3D Or, in order to not open another question, what are other (tricky?) ways to expire S3 links without the use of proxy?

• Can UML with OCL be used for formal specifications?

  - by Gabriel Šcerbák

  I am asking because UML is used for informal specifications and has some ambiguities in its semantics. However OCL can be used to specify pre/post conditions and invariants and other constraints quite efficiently I think. I encountered the Z notation and algebraic specifications recently. My question, is combination of UML and OCL sufficient for formal specifications?

• How does assembly language interact with something like the Internet?

  - by Maulrus

  So I was thinking about languages the other day, and it struck me that any program written in a compiled language that interacts with the Internet is then translated into assembly that has to interact with the Internet. I've just begun learning a bit of x86 assembly to help me understand C++ a bit better, and I'm baffled by how something so low-level could do something like access the Internet. I'm sure the full answer to this question is much more than would fit in a SO answer, but could somebody give me maybe a basic summary?

And what are some examples of successful software applications that were developed by just one man (or woman)?

• Why is a 16-bit register used with BSR instruction in this code snippet?

  - by sharptooth

  In this hardcore article there's a function find_maskwidth() that basically detects the number of bits required to represent itemCount dictinct values: unsigned int find_maskwidth( unsigned int itemCount ) { unsigned int maskWidth, count = itemCount; __asm { mov eax, count mov ecx, 0 mov maskWidth, ecx dec eax bsr cx, ax jz next inc cx mov maskWidth, ecx next: } return maskWidth; } the question is why do they use ax and cx registers instead of eax and ecx?
