Re: SSL Not So Secure

We spent most of the day discussing this at work yesterday. Pretty nasty, although the solution (or the only thing left to do) is workable: patch openssl, regenerate certificates and probably reset passwords for everything. Thankfully, this doesn't affect elysianshadows.com, because it doesn't use s...

Re: Syntax Analysis parsing methods questions

Well, I'm not aware of any compiler doing this, but I think it is common on other applications of parsing. The idea is that during the syntactical analysis, if you see this: x = 1; the output can be: if the semantic analysis is tied to the syntactic analysis, produce the actual output of the compile...

Re: Syntax Analysis parsing methods questions

Hi! Good to see a different question around here ;) It all starts with the grammar. Say you have a simple grammar: <a> ::= "a" <a> | "" Suppose we have the string "aa". In a top-down approach, we would have the following steps: Start with the root of the grammar: Parsin...

Re: What books would you recommend for c++

The Holy Scott Meyers Triad (Effective C++, More Effective C++ and Effective STL) is also recommended after you've got the basics down. They're from the mid-90's, but most advices still apply today.

Steam dev days

Thought it may be interesting to you: the videos for the talks at Steam dev days that went on a few days ago are available. I'm watching them, they're good quality videos and some of them are probably relevant to some of you (even the ES team).

Re: Dreamcast Dev: libimageload linker error

I don't know if this is the case (not familiar with dreamcast development) but the order of libraries on the command line to the linker matters. See here . Basically, if you have an object a.o that needs something from b.a, you need to put a.o before b.a, so that the references on a.o are resolved w...

Re: Programmer's Education Index

Uh On second thought I think I'd die if I double major To be fair, it's not really twice the effort, because most of the classes are the same, so you wouldn't have to do them twice. Ehhhh, I don't know what your curriculum is like but there is absolutely zero overlap between CS and EE majors here. ...

Re: Wavefront files with Blender

If the points are correct, my guess is the edges are being loaded incorrectly. Create a simple model and take a look at the data produced by the code that loads this information from the file.

Re: Windows.h

First of all, you need to understand the concept of a header file. A header file doesn't "do" shit. 99% of the time, with the sole exceptions being inlining and macros, a header file doesn't even contain any executable code. All it contains are the definitions of data structures and the d...

Re: Programming Trivia Questions [HELP ME OUT!]

Considering that the majority of my co-workers do not work in C++ (ever), even a question as simple as asking for the correct syntax of a function pointer would blow their minds. If the goal is for everybody to learn something new, I think it'd be a nice question, could generate some interesting di...
