Disclaimer: I'm new to the REST school of thought, and I'm trying to wrap my mind around it. So, I'm reading this page, Common REST Mistakes, and I've found I'm completely baffled by the section on sessions being irrelevant. This is what the page says: "There should be no need for a client to "login" or "start a connection." HTTP authe...

Yes - Google abounds with information about configuring Apache to support SSI. But unfortunately, I still cannot seem to get it right. My questions: Can anyone furnish me a full-fledged example config file that enables SSI on an Apache server? Also can you please tell me where I should drop this config file (i.e. which dire...
Hi, EDIT: Ah ha! The solution to my problem was simple afterall! I'm an idiot :D I was so focused on why it was taking so long, that I was blinded by the fact that my object pool allocate() function is lazily evaluated. i.e. It won't allocate until it's called. But my timer test was around alloc, so obvious the first time through, th...

I have started with the third year of my bachelors degree. I don't hate computer Science, it's just that i loved physics a lot(I dunno about...
Project Euler has a paging file problem (though it's disguised in other words). I tested my code(pastebinned so as not to spoil it for anyone) against the sample data and got the same memory contents+score as the problem. However, there is nowhere near a consistent grouping of scores. It asks for the expected difference in scores after ...
Hi, i'm a little confused about EF4, and the EF homepage doesn't help me, so... First thing: is EF4 a separate download or is it a part of VS2010? What version of EF is native in VS2010. Reason why i ask is because i create a .Net 3.5 project in VS2010 (.Net 4.0 is not yet on the production server) and when i want to check the checkb...

With web based MVC frameworks the view and model never communicate directly. They can only communicate with the controller. But in desktop implementations, it seems that the vie...

I feel like this is probably a pretty dumb question, but I am just completely lost. I have seen (and tried) about ten different ways to install EtherPad on my system, but absolutely nothing on how to actually incorporate it into my web page. One page seemed like it was telling me to open up "http://localhost:3306/" (or something along th...
