/prog/ - Programming

>>4289

sticky seemed to be recommendations of math books for programmers (I've read a number of them) whereas I'm more looking for a programming book for mathematicians

>>4288

>is there a more general book I could read alongside, a guide to the structure and thinking process of programming?

Try this:

>>4293

yes! this is more what I was looking for thank you anon

>>4264

My reason for entering the world of programming was to make games, so I started with shittastical yet fun engines like GameMaker. Gave me a feel for what kind of structure a game program needs. Learning C# after having used gamemaker for years allowed me to see what object oriented programming and polymorphism really are. I am now trying to get my head around C++ OOP to develop in Unreal Engine.

Alacrity

It can work!

I had this idea because I wanted to make a browser-side BBCode parser. So users could edit it however they wanted easily.

So I needed an excuse…

>>3764

I'd like to see you faggots make a peer to peer chan like this.

>>3764

Prepare to be exploited m80.

You're going to let the user keep his forum files locally and then upload them to your server temporarily? Gonna be rough keeping that from backfiring.

>>4309

This x 100

>>3764

OP I'd say that the best way to do something like this is to have the user keep an encrypted file container not with their own information but with bits and pieces of everyone else's info a-la bittorrent. However, JS would not be the language to code something like this in. You'd be better off with C, C++, or even Erlang since you're going to be doing distributed computing. Might also want to peek at Pony because it uses object capabilities and actors. Some very powerful stuff under the hood.

I had a similar idea to yours. Its doable but it will ultimately fail if you do it in Javascript. The other user is right. Allowing some dick to upload info to your server is asking for trouble. Information has to be securely stored, tamper proof, and safely transmitted.

In summation: a distributed/P2P system that requires the user to upload his information is a good idea if its done properly. The user must not be able to edit his own info except through a secure web interface. The data itself MUST be encrypted. Otherwise you need a way to sandbox each user's code.

Maybe check out Google's Caja? Its a variant of Ecmascript that uses capabilities.

>>4282

Is this a virus?

>>4303

Please don't compile that code. It right fucked my computer… I'm getting a new HD today.

>>4257

>To be fair I had this problem too when I was a noobfag. I wanted to create new variables using a for loop but didn't know how the fuck to do that. Now I know you can't and must use an array.

You're still a noob. Learn how namespaces work, idiot.

>>3717

Sure, OP. Other fags here don't seem to know how to answer basic questions because they're actually stumped as to how to perfectly emulate your code. It's easy, actually.

for (var x = 0; x <= 3; x++) window['a' + x] = document.getElementsByTagName("audio")[x];

After that code runs, you can then reference a0, a1, a2, and a3 as normal.

You might want to consider making a namespace of their own to go into though, that way they won't just be tossed into the same group as everything else.

>>3720

Get off this board, idiot. Don't answer questions if you don't know the answer.

>>4276

Just build the habit of declaring variables const, man.

So… I decided to go full retard, if anyone's interested:

# This patch adds an option the the C compiler: -fdefault-const
# When this is enabled, everything will be a constant by default, and only be mutable if specified with the "mut" or "mutable" keyword.
# I tried to implement this the easiest way possible, by just flipping the const_p bit, and adding the keyword (reusing "mutable" from C++).
# Unfortunately, the fact that const_p is a single bit makes it hard to get everything right, as some checks assume that a keyword was specified only if the bit is on.
# As such, I had to flip the bit to "fix" a warning, but with a consequence: If -fdefault-const is enabled, it will only warn about "mut" being specified at the wrong places, and if not, it will only warn about "const".
# This was only tested and works with regular C. I haven't tested it on C++, so the option is unavailable there.
# The only effect this has on C++ is a new keyword: "mut", that means the same as "mutable".
# Also untested is compatibility with library headers such as libc.

>>4284

That's actually cool in a hacky way, but you are aware that that makes the language you are using not C, right? That will affect not only the code you write, but all imports as well, meaning many libraries will need their headers rewritten before you can use most of them.

>>4296

I'm aware. That's the reason for making it a compiler flag: if you want to compile external libraries alongside your own code, you just make them compile without that flag.

Library headers will need to be rewritten indeed, if they define structs you have to modify (as the members will be marked constant by default, and may need to be modified), or define any functions.

I'm writing an OS from scratch, so I don't feel the consequences as much as when working in an environment with tons of libraries.

Also, I updated it, fixed another warning related to functions with only void as a parameter.

> #define int

Yes, this seems like a good idea.

>Learn how to design and use databases

These are good bonus skills but there's such thing as DBA staff

>>3822

There's some development related stuff like version control, continuous integration and testing, you probably won't read about those in general books on Java. You're probably not expected to be familiar with those as a junior, but then again, those are good bonus skills. And unlike databases, those 100% will be useful.

>>3825

Most of the time, I've been expected to make the whole application. That includes designing the database.

Gotta agree on version control, though.

>>3824

>>3825

All right, I'm saving those posts even though I don't yet know what most of the acronyms stand for. It seems that some research is in order.

Thanks guys.

>>3815

I learned this summer that lectures are fucking shit after I started studying my text books due to getting less than desirable grades last semester.

With text books you get full explanations and good examples instead of shitty TL;DR's and scribbled slides/diagrams.

>>3813

If you'd like to learn game development, I would suggest C# (which is like Java) and then moving on to Unity.

If you want to learn Java for games, after your beginners book I'd suggest Data Structures and Algorithms in Java by Peter Drake. It's an intermediate Java book which teaches many of the data structures you'd use in game and the examples are simple games which makes it fun.

If you want a day job programming, your best bet is to learn C# or Java, and SQL Database programming, and Javascript/CSS/HTML. You'll probably have to learn a ORM or two, but please make it a point to learn how databases work, because I run into programmers now who are clueless about how a fucking SQL works because they use shit like Hibernate their whole lives.

Really, if you had to learn just one thing to get a job, I'd say learn SQL and SQL Server. It's been around forever, it really doesn't change, and if you're near a major metro area you should be able to find a job with that.

So, uh, he said that the main problem of haxe is being unpopular and hxcpp having high bus factor, that's all?

Kikewheels, let me post

>Is it just because it is unpopular

I hadn't heard about this language before seeing this thread. So, probably.

>Is it just because it is unpopular

Hotwheels pls, your site is defective

>>4076

> Is it just because it is unpopular

> that's all?

Also, the Haxe Foundation not making the necessary effort to spread the word that Haxe exist and is still actively being developed.

>>4036

It's fine, it's quite comparable to Java/C# (statically typed, garbage collected, OOP) but has a nice macros and slightly less verbose syntax. I enjoyed it.

Have you guys used openfl with haxe and the html5 target?

>>4154

Are you the guy that made this post?

https://8ch.net/prog/res/1410.html#4152

>>4106

C because you can learn it knowing EXACTLY what's going on, what the code is doing and what the hardware is doing.

Many people recommend super high-level object oriented stuff for a beginner language because supposedly it's easy to use and easy to understand because muh representation of reality with OOP.

Then they end up on stack overflow like "So I'm writing a hello world but the compiler says i'm missing an abstract virtual base private destructor".

In languages like python or c# it's easy to do advanced things with little code but you won't know how it all works and it will bite you in the ass later.

In C and perhaps other low level languages it's easy to know exactly what's happening.

>>4154

was trying to start with this but a black screen with a ">" is the only thing I see. What do?

>>4201

That's the REPL (read-eval-print loop). You type expressions in it, it evaluates and prints them.

If you dont care too much about the look but more about the funcionality, I would recommend you to use bootstrap or another html/css framework, they make that shit way easier. Its mean using html with a css and js made by another person basically.

go to codeacademy and do the html/css course.

After that use bootstrap, foundation 6 or mdl.

>>4236

I know but it's what Wordpress uses so I need to learn at least a little bit about it

I know PHP. How do I git good with CURL. I want to make some webbots. Also know bit JS. I see lot of things on node, angular and shit should learn them to make some meme stuff?

by lurking more

literally everything you need is on this board already. look for it

Javascript isn't too bad, it's just being used for something it wasn't designed to do. Hence every update is essentially adding more duct tape to the shitshow that is the web.(not the mention the hell that is php)

Stallman has done good I'm glad for the GPL even if it's not for ever open source project but he is himself just mad, if he didn't start something he just doesn't like it and gets his followers to help.

There is a need in standard, high performance, dynamic language that also supports functional and OOP paradigms.

JavaScript perfectly fits this niche.

Modern javascript runtimes are very performant. V8 is the fastest compiler ever written for a dynamic language.

Using a modern dynamic functional garbage-collected language like JS speeds up development 3-5x compared to C/C++ (development time and source code size). No more segmentation faults, no more memory micromanagement. you write your application and it just werks.

My unpopular opinions are neatly summarized in this artwork https://ngnghm.github.io/

Best technology always feels like magic.

Best programming language should be just a natural language interface allowing the programmer-user to specify his/her task to the machine and have it executed.

your physical appearance has an impact on how people perceive and interact with you. you will be perceived as a lazy slob if you're fat.

a high quality of life means you benefit from the positive feedback cycle, and in turn are presented with more opportunity.

>>3683

>what did you do to get a career in programming going? What do?

I got an AS degree at school, and made some important networking connections with other students and professors.

I then got an opportunity to interview with a small company and they quickly offered me a 90-day internship, after which they offered me a full time salary as an engineer.

>>3696

If you spend all your time on a computer you'll eventually hate it. You need a hobby that doesn't involve the logical part of your brain.

A bit overkill but it was fun.
