I am from an animation and design background. I have a long-term app project in mind but I'm almost a total beginner. I am literate enough to read Java the best.

I am currently reading a C# book which claims to teach good general programming but the format of the book is very slow. This might sound precocious but I am eager to jump into writing a functional app ASAP. I'm essentially trying to create my own day planner with task setting, tracking and completion.

I'm not looking for pointers towards this straight away, but which language is best to start in, and which exercises are most beneficial? Sorry if my neophyte garble annoyed anyone.

learn the logic, everything else comes in time.

search up logic books and pseudocode stuff. this is more important than syntax of each language, everything works based on the flowcharts and pseudocode anyways.

I've been using an electronic drum kit to my drums in Ableton Live, but Ableton's default drum rack, while still being the best for what I need, doesn't do everything I need it to. But all the other drum VSTs I can find are even farther away from what I need. The task seems to be bigger than the one friend I have who can program things so I'm wondering who I should ask. Where (IRL or online) and how would I go about finding a professional who could make a custom VST? And how much should I expect to have to pay? I can share more details on what I need if there's anyone who can answer this for me, or on the off chance that someone here would be interested in the task.

I am not an audio expert, so I can't really speak to the audio-specifics of your request. But from my brief research it looks like you need a VST plugin to be authored (probably a VST 2.0 plugin, since they are more compatible with more software than VST 1.0 or VST 3.0 plugins). Steinberg released the VST plugin specification so that people can author their own VST plugins, and also so that various sound and music tools can integrate VST plugins. Typically these plugins are authored in C++ (as on Windows they are basically just DLL files).

I think that if you want to find someone who can make your electronic drum kit do all the things you want it to do, that you'll probably have to talk with an audio engineer (who knows C++) and find out from them what they think it'll take. This will probably depend heavily upon what features you want it to have that you don't already have access to. I don't know what the going "rate" is for purchasing plugins generally, so I cannot assess a price.

Getting glew to work on windows in codeblocks

I have a question about something not working in my coding. Normally in these situations this calls for throwing out some easy answers with a healthy dose of derision and scorn.

One: What must i do to convince you that i have tried my best to solve this before coming to you?

Two: I request someone to walk me through the solution to this problem like a parent dragging a young child through a busy city street. I have worked at this for so long, that i am starting to lose confidence i ever knew anything at all, and i consider it fully possible that i am missing something on the level of "Is the cord plugged in?"

Okay, here's the problem. I am learning openGL. I am using this website to do it: https://learnopengl.com/, i am currently walking through their 2D game tutorial shown here: https://learnopengl.com/In-Practice/2D-Game/Setting-up and i cannot, for the life of me, get glew to work.
I am on windows. I am using codeblocks. When i do everything i know should work, i get a shit load of undefined reference errors.

http://prntscr.com/kbj3zs

That says to me that i am somehow linking to the glew library wrong. But i have been trying fookin' EVERYTHING. Literal days. Possibly months, because this isn't the first time i've tried to tackle this - i think i gave up on codeblocks last time and just used visual studio, because for some reason that works easier - but i don't know why and that's terrible for learning.

When i DONT use glew, i can make openGL programs just fine. Hell, given how much time i've invested in this, and how it's likely that there is NO solution known to god or man, i'm probably better off just figuring out what the tutorial is trying to do and figure out how to translate it OUT of glew than get glew to work. But the fact that it SHOULD work and i can't get it to is making my brains leak out of my HEAD.

So if you believe me that i wouldn't be asking you if i could find a (WORKING)solution anywhere on google, or glew's support pages, or shit like that. Please please please tell me how to fucking do this.

I have no idea how to build things on Windows except with MSYS2, which Google says you can use to build GLEW.

You could try using the mingw compiler directly from the command-line to compile and link your code. Alternatively, you could try using Clang from the command-line to compile and link your code.

Both of these should work on Windows (provided you make sure to download the version of Clang that builds on Windows for Windows, as opposed to the version of Clang that builds on Windows for Linux).

What's the deal with C++ templates?
I'm looking for explanatory videos on it that is reasonably well produced
(not some enthusiastic dude rambling to a screen recording)

Doesn't have to be a video though if it's well written. All explanations I've found so far don't give me any reason of why to use them at all (instead for instance method overloading)

Some time I'd need to for instance loads of static data that I could define by hand but still would like to take advantage of encapsulating things that resemble state machines in classes.
I use C++ for microcontrollers, never on a PC and some times access to hardware can't be done inside a class the straight forward way, like storing pointers to a hardware pin, timer register, etc... inside anything non-static.

You can do a lot more with templates than just generic types like some noobs would say. There is a famous book on templates called C++ Templates: The Complete Guide. You can find the first edition easily and I have also found the second edition online for free but it seems to have been taken down by now.

The crux of the matter is if you want to get the interesting stuff you basically have to break into some system to get training data. (Or risk your job and get it from your employer.)

That said I don't use the equality operator in most cases.

Where type coercion is useful are (sadly neeccesary santiy checks like)

if (thing && otherthing && thing[otherthing] && thing[otherthing].value ) {
// use thing[otherthing].value

Soi don't know much about programming
I've been using computers since I was basically born and remember rainbow logo macINTOSH computers when're that was a thing
I've decided I'd like a career change

I want to eventually deal with AI or Cybersecurity
And by AI I am pretty certain I mean a type of machine learning where you build a "neural net"
I think thats like the predominant thing in that field right now
Im really interested in for lack of a better term "future tech" like bioengineering and anything that has to do with the human body and tech kinda "merging" in any sort of way
I've always really been so interested in the way networks and computers interact which is why cybersecurity is another thing Im really starting to look into, I think computer forensics falls into that category tooI guess that involves "hacking" to an extent to understand how to attack/infiltrate a system?

I'd like to learn on my own and slowly build a kinda portfolio and eventually when I think I'm good enough try and contribute to any ongoing projects or something, to gain "clout'
(really more like rub shoulders with people who can help me later haha.)

But before all that I'd really like help figuring out the best avenues of action from you guys hence this post and all that.

Im in-between cyber security or AI
I also have a buddy thats die hard for blockchain tech and while I'm not a bitcoin radical, I do know a lot of money is pouring into the blockchain engineer space
so that is also something that might be interesting.


I'd appreciate some well thought answers, I always ask 420chan for advice like this, I just love you so much you know?
Sorry guys, Im all on drugs and introspective and wish I had a dad but ANYWAY like I was saying, those all sound interesting for me and my question is what languages would help me the most to do those right now assuming I know nothing?

I think over time its important to learn a lot of languages for different reasons so its really hard to have a definitive "BEST porgramming language to know EVER" but what would you think are the best
languages for a novice to learn are? For cybersec or ai?

Might actually combine, my editor of choice [Textadept] is purposefully small sourced at 6k LOC total, maybe I'll try to remake it in Common Lisp. Still kinda a larger project than I was going for, but since I have something to work from it might work. Kinda like a pixie emacs in CL instead of eLisp without all of those features.

And then integrate a text adventure right into the editor, cause emacs

Clarifying, by combining I meant that then I actually have a reason to read through some real source, I've known that I should but I never get around to read just for readings sake. Doing it for a reason (rewriting) gives cause.

Going in I realized I have no idea where to even begin. There's loads of source files and I've no idea which one to start reading in. I'm pushing on though.

Programming is a craft. If all you've ever done is toy CS programming then of course you can't make anything. Try a software engineering course or apply for Google Summer of Code or just look at some small open source applications. Also a lot of CS people can't write software to save their lives, so don't sweat that.

The book called 4 hour workweek inspired me to develop this system. What it taught me is having a business is good but having a formula for it is better. There's no doubt scaling with no resources is hard, but in a way that is the essence of scaling.

Hi guys and gals,
My C++ program (a roguelike game with lots of lists) is becoming pretty large. As I try to clean things up, I’m noticing I’m creating huge ass functions with many arguments (since I’m passing so much data sets around).

I think I’m pretty meticulous about keeping track of everything, so it’s not that I’m running out of computer memory, it’s just the code is impossibly long and ugly. Is it normal to have functions with 10+ pointers to different datasets, etc.?? Or am I dokng somethig wrong - any idea how to fix it?

Id love to hear your ideas!!

The lambda expression comes in handy for partial application because you can't nest standard functions in C++. Plus, if the lambda is only meant to be a helper for one particular function, you wouldn't want it to pollute the global name space anyway.

Yes, roguelike games have many pointers to different datasets like: character attributes, monsters, spells, potions, locations.
And the routines can be very very long, especially the case statements covering all possibilities.

In contrast to what others say, generally do not split routines into smaller functions if there is only one caller. Otherwise you will be scrolling all over the place and making a bigger out-of-context mess than you can imagine.

What you should do is avoid global variables. Collect them all into a larger struct and pass that along as a pointer to a 'global dataset'.

Look into nethack and ularn for comparison.

This is a hard question to explain because English is not my first language.

I have a game coded with socket.io that uses a persistent world. When a player clicks play, he enters the world and can manipulate it like singleplayer Minecraft. However, many other users can access the server at the same time and modify the world so that the first player sees modification, but none of the players can see each other. All enemies, bullets, etc are only for each individual player. Players only can see world modifications of other players.

I want to make it so groups of 2 players can player simultaneously. So these 2 players can see each other as well as world modifications of all other players. Would I just have to have multiple servers? I want to just use the 1 server to let groups of 2 players to play the game like how solo players play the game now. I can't afford to host many small servers.

Since your game is like Minecraft, you could simply have one very large procedurally generated world that was so big that it's highly unlikely that any group of 2 players would ever run into one of their neighboring groups of players.

I'm looking for something a bit like std::map, except that I don't care about a <key, value> pair; I just want to be able to say to the thing, "here, keep this integer". And "hey, have you got that integer, yes or no?"

Something tells me a hashmap isn't the right tool for the job, but I can't seem to figure out what is. Any ideas?
