Re: var me = new Patashu(); AskAnything(me)

can we team up and code a gameboy game? just need to know C and I can make some ballin music

Gameboy games are not coded in C, they are coded in an assembly language called Z80. Unless some amazing dude wrote a C -> Z80 compiler in which case hit me up

You into making games?

I tried several times when I was younger but never 'built up the steam' to get something going. I think if I had though I'd have finished and enjoyed it. I'm of that kind of personality type that has difficulty doing things without progress and sense of direction. I tried making games in BYOND ( http://www.byond.com/ , a tile based multiplayer client + game designer) but always got stuck on things like 'I need a shitload of assets for this game so I can make a prototype and not want to gouge my eyes out, let's start making some... making some... making some... aaaa I'm bored' and 'I don't know how to do X, this language is a bit weird... I don't know how to do Y, I don't know how to do Z, I can reason to myself about what it should do but not figure out how to code it in BYOND'. So I never got anything started. But I came up with big ideas for things like a multiplayer tank game with robotron style controls (one hand moves other hand shoots) and swappable parts, a mazing tower defense game where all towers formed a 'tree' of upgrades and you could pick the next (I remember that you started out by picking sword for speed, axe for damage or halberd for range for example), a tile based party MMO-lite where you could only get a benefit from doing things/killing specific monster spawns X number of times, so you'd eventually have to move on, ... If you like you can ask me about any of these, I still remember them.

This seems like a big excuse post, so I guess I'll just say 'yes, but I lack the will to start one' in summary. I also did make a simple game for University but it was a bit rushed since I had three other subjects that were worrying me more. http://www.youtube.com/watch?v=wArB3j0kn64

Sometimes I wonder how my life would be different if I didn't find FFR/Stepmania. I only got big into them because a very recently made friend on AIM sent me arch0wl's videos on quasar and reality, and I was like 'wow, this is crazy, how do you do this' and he introduced me to FFR and a little later stepmania. I played one handed for months before swapping to spread. Before Stepmania I did not have any kind of passion for music - I liked only a few video game tracks and otherwise did not listen/care for it at all. I was also really big into Meteos, but I quit that later when the psychology of grinding it got to me. (If you've ever played or watched Meteos deluge mode, you'd see that the speed at which the blocks fall speeds up exponentially - and the grace time between a column filling up and you getting a game over drops - as a result, until you are good enough to reliably clear the screen even with arbitrarily fast dropping garbage, you will always fail early on. Think about AAAs in stepmania - if your chance of hitting a great isn't like 0.1% or lower you will almost never get an AAA. So, while I got very good I didn't get good enough to break through and that finally discouraged me one day when I was trying to record a video on Cavernous and my nerves were shot. It got to me.) I wonder if, if I didn't get into Stepmania, I'd find something else to replace my time - or just not really have any meaningful hobbies. Unfortunately browsing the internet, watching videos, watching stream, chatting, etc. don't count as hobbies, skills or things you can get better at, yet they have a tendency to occupy all of your time if you don't exert a strong will against it. I had to block myself from twitch.tv and speedrunslive.com recently because of how obsessive I was getting about it. Alloting myself the time to do something in Famitracker is tricky because I have some conception that if I don't have at least an hour uninterrupted I won't be able to do anything meaningful - Hopefully this is a conception that will break down once I get good enough, fast enough and pre-loaded enough that I don't have to think as hard about everything I do, whether I could do it a bit differently, etc. Like I notice how Kommisar always uses the same basic kick, hats, crashes, etc - while I'm coming up with a new everything-but-snare every time I sit down. It's good for playing around with things but not for being productive and getting things done, I guess. In any case, I'll doodle on my ipad running a keyboard app or on my practice drum set without caring about how long I get, so I always have that to practice my creativity and skill on at least.

Re: var me = new Patashu(); AskAnything(me)

I was actually reading about C++11 lately. 'auto' looks great, lambdas look great, constructor chaining looks good, override/final look good, rvalues and move constructors pique my geeky sensibilities. What I'm noticing though is that these are all features (except for rvalues of course) C# has already had for some time - so while C++ is still considered the language for programs that need to run fast or on embedded platforms, it's not a good fit for anything else. Although this stuff definitely lets it catch up, you still need to think about much more than you have to in managed languages, like how to manage memory and resources (RAII, smart pointers, etc are still all opt-in), how to design your classes with copy constructors, etc in a safe way, how to handle strings and buffers safely, how to handle pointer arithmetic safely, etc. all in the name of performance. It is definitely a better language for flexing your brain on, but most projects don't need it.

Some programmers are of the view that students should be forced to learn hard languages rather than easy ones (C++ and Haskell instead of Java and Python) to weed out people who shouldn't be allowed to program anyway. This is the kind of thing that would make for a great debate topic and I haven't fully made my mind up about it yet. Personally, I grokked C and C++ fine but Haskell I haven't looked very hard into yet.

EDIT: Hmm there is a lot of cool shit being added to C++11, I'm reading the wikipedia page. Oooh shitloads of random number distributions, oooh 'function pointers', oooh metaprogramming, Ooh **** yes regexes. And it goes on. It is actually a pretty big jump: http://en.wikipedia.org/wiki/C%2B%2B11

Thanks for the thorough response!

Regarding the first paragraph, this is precisely why C++ is my language of choice. I don't like details being hidden away from me and would rather control it myself. In the industry, I realize this mindset isn't going to fly because it's all about the bottom line, but I take pride in writing efficient code so getting to the metal helps me do so, so I use C++ when I can.

I'll share my opinion with what you said in the second paragraph. Basically, I feel that lower-level programming languages should be taught before higher level ones because using the lower-level ones help produce more optimal assembly code, and consequently machine code. Also, hand-holding is not the way to be taught how to be a better programmer. Computer Science Curricula might as well throw students into a low-level language head first, since they are going to need to take some type of computer architecture class anyways.

Finally, the last paragraph is pretty much why I asked what you thought about the new standard. There is so much new stuff in it that it basically makes C++ a whole new language. I haven't seen any open source stuff written with C++11 features, so I can't say how effective it is in a real-world application, but it sounds really good on paper.

What do you write that needs to be so efficient?

I didn't get any computer architecture classes when I got my degree ;_;

The thing about 'learning assembly makes you a better optimizer' is that the most important part of optimization is reducing big O notation. (Well, actually, it's not optimizing until you need to. Whatevs) And doing that requires a strong algorithmic grasp, and you don't need much low level knowledge for that - you just have to be aware of what things execute in constant, linear, logarithmic and quadratic time under the covers. (Sometimes hardware comes into it - hard disk accesses vs ram accesses, sequential hard disk access vs random hard disk access, cache misses and thrashing, etc). Often your optimization problems are solved by using a different collection type (priority queue, tree, hash map), adding on a cache, failing fast, figuring out how to use one less loop and so on. These can be understood intuitively in terms of their algorithmic qualities.

Like, if computer science courses should make you 'industry ready' they'd have a focus on molding your brain around very huge codebases and projects. This is a different kind of difficulty and one more relevant to most disciplines (maybe you'd get to pick a course to take? low level programming or big mclarge huge programming). So it would still be hard just different-hard, and as long as you're getting challenged you become more disciplined and more familiar.

There are exceptions of course, besides embedded programming. Video/audio processing and pattern recognition algorithms are almost impossible to grok unless you are thinking at a very low, hard level about them. And since they're so intensive they basically have to be C or C++ coded (such as OpenGL).

Finally, the last paragraph is pretty much why I asked what you thought about the new standard. There is so much new stuff in it that it basically makes C++ a whole new language. I haven't seen any open source stuff written with C++11 features, so I can't say how effective it is in a real-world application, but it sounds really good on paper.

All the stuff that's highly utilized in managed languages is trivially useful, and the rest of it all looks like an improvement too. Good stuff.

Basically like you already said, embedded systems. Well, it is my primary interest as of right now. There is a defense contract not too far from my school which does embedded development for the department of defense, which I would like to pursue. Also, parallel computing was my second choice of a career path to pursue. Basically, anything that involves getting the most performance I can out of a computer, because I'm a performance nut :P

Yes, knowing how to mathematically analyze an algorithm is an important part of writing "better code", but it's just that; a part. That's why I mentioned a computer architecture course for all of the hardware related stuff (my school has one, luckily), which is another part of writing "better code". I may be a bit OCD (more than likely), but like managing my own memory, I like knowing how things work under the covers, so I can feel confident that I wrote something as efficiently as I could given my knowledge.

Can't comment on the second paragraph since I don't have experience here since I am still in school.

Finally, the third paragraph was basically what I was getting with the first part I quoted and answered.

That is cool, but most of the time what I write is fast enough that I don't need to worry about doing memory management manually or anything else, which is why I don't program in C++ by default. So it depends a lot on your problem domain, if you do scientific analysis/image processing/similarly hard data processing you'd probably pick C++ by default again.
