| Disorder v0.08_alpha : Portals | Version v0.08 of Disorder's portals. Why a new post? Because those two small 0.02 versions really changed a lot. - nicer "test level" - extremely smooth player transitions (it used to be jerky and you could see the wall when passing through - n... |

| College courses and AP exams | Hey guys I have a few questions for you this time: (background: USA, currently a sophomore in HS) 1) Does the AP Comp Sci exam actually mean anything to most good colleges? The AB exam used to be pretty comprehensive but now that they dropped AB... |

| Linked lists are slow? | Consider this code: #include <iostream> #include <list> #include <vector> int main() { std::list<int> nums; for (int i = 0; i < 1000; ++i) { nums.clear(); for (int j = 0; j < 500... |

| Triangle order in VBOs | Are triangles in a VBO guaranteed to be rendered in the order that they appear in the VBO? (and, assuming no Z-buffering, they would also visually appear in the same order) Or is there no such guarantee? I cannot find a source that says either po... |

| A*/Dijkstra optimization | I've recently gotten into path finding (especially via A* and Dijkstra's algorithm, which is essentially A* without a heuristic) and I find it very interesting and fun! My first implementation was extremely buggy and slow. I've gone to make it wo... |

| Link to .exe | Consider that foo.exe links to static library bar.lib. Can I now make baz.exe that uses functions from bar.lib by linking to foo.exe? AFAIK, if I know the addresses and signatures of functions in foo.exe, I can explicitly call them. But is the... |

| Best SC++L Reference Book | There's a competition that my school enters every year and we're allowed to bring a language reference book for every language we use. For Java we'll just bring whatever we brought last time, but what is a good reference book for C++? I'm mainly lo... |

| Proving logarithm rules | We're doing logarithms right now (grade 10 honours math, the US math curriculum goes incredibly slowly... but that's another topic), and one assignment was to prove logbx - logby = logbx/y This is what I did: logbx - logby = logbx/y let m =... |

| Circular Breakout | This is a little circular breakout game I wrote in the past 9 hours (from scratch). The screenshot is a little boring, but I didn't want to spoil the more interesting parts of the game [wink] clicky for download Details: - written in Ja... |

| Field experts | (not sure if this should be in the lounge since it relates to general programming) Today in AP Comp Sci (I'm a sophomore in a USA high school, 16 years old) we had a junior from college come talk to us about college (Stony Brook in his case) and p... |

| trying to solve encryption | Things to note: 1) there are 3 numbers in decreasing order, then groups of 4 numbers in decreasing order 2) if you reverse each group of numbers, you get an increasing sequence 3) each 2 corresponding groups have the same sum for each 2 elements... |

| do/while loops | Quote:Original post by theOcelot I don't understand why that is even legal, and I'm not sure I want to. [sick] Essentially it uses the switch to jump into the do {} body and ask the user without complaining first, then the the actual do {} whil... |

| Check out my ray traced images | Run your RT with a basic sphere centered dead-on in the middle (preferably unshaded, just white = sphere, black = background). It should look like a perfect circle even without AA, it shouldn't have those jaggies. See them? If you'd like to show u... |

| Strict OO principles vs. speed | Quote:Original post by Antheus Here is a nice problem of why "OO" (whatever that means) is problematic. Object-Oriented, nicely encapsulated linked list is 100 times slower than data-centric versions, despite doing exactly the same work. That d... |

| A little confused by java | Quote:Original post by Telastyn Right, I looked at that list, and it's next to useless since it's mostly problems that only exist if someone is coming from C/C++ No, actually, there are many issues regarding Java itself (i.e. the whole secon... |

| A little confused by java | Quote:Original post by Telastyn Mmhmm. How exactly is Java very broken compared to C#? There's one major issue I can think of, but that's not enough for me to make that qualification. Um, simply click on the link I previously posted... |

| A little confused by java | Quote:Original post by Telastyn They're also by and large a list of things C++ developers might be confused by when moving to Java, rather than Java failings (not that Java doesn't have a few). And to be honest, it's a far shorter list than C++ gotc... |

| A little confused by java | Quote:Original post by Fenrisulvur Quote:Original post by nullsquared You're completely right. But C# is not broken - you can write a proper swap() via generics and ref [wink] C++ has broken encapsulation, and you're worried about a swap idiom? &... |
