Also webdev is not as much of a meme as /dpt/ makes it out to be, especially for back-end. You have to learn a variety of languages and frameworks, and it's pretty similar to application development, barring it being on the web

Most people consider that a bad thing, you know.
>>54063290
pic related is due to optimization quirks, Java iirc stores integers from 0-256 in memory, so a100 and b100 point to the same thing and so are equal. There's nothing wrong with optimization if you know how the language spec works, you can do C optimizations if you abuse weird quirks like overflowing into another block of data, and people will call it shit
That being said, it's the least of Java's problems, lack of pointers and memory management is the crux of issues like this, along with other points that make it a shit language

>>54063314
Literally anything.
Don't listen to the autists on /g/
Here have some reasonable advice:
- C++ is the industry standard because it allows you full control of memory and speed, and allows for nearly every paradigm. You don't need to use this language if you don't need the above.
- Python and Ruby are fun languages made to be simple and easy to get small shit done. Use this for simple stuff like conway's game of life. IMO their simplicity is subconsciously geared towards programmers, making it not as good of a beginner language as they claimed. I have some weird ideas for what would make the ideal beginner language but I won't explain it in detail
- Java still carries outdated shit on its shoulders, like C++ except without good reason. OOP needs to disappear from the mainstream and can't come soon enough
- Haskell pure FP is a meme but it's really fun working in Haskell. Even though dependent-typed languages are arguably more powerful, more research has gone into making Haskell a usable language
- C is incredibly difficult to program anything worthwhile in, and you should nearly always write in C++ unless you are working really close to metal.

Same, but it's because of these lower-level quirks that people will make memes out of C
>python-hate
I'm not in the business of reinventing the wheel. I would make intensive things like emus/games in C, but there is little gain in not using python when speed isn't an issue.
I see a lot of hates on globals, but what about static methods and members?
Aren't they practically the same?
>>54063368
If speed isn't the issue you should be using F#

Daily reminder that C++ is deprecated by C11
>>54063372
No, static methods and members are better, and you can use CRTP to subclass it, and while you're still polluting the global namespace, it's all contained in a class. Global things in general are disadvantageous to scalable programs due to coupling and other factors, unless you've limited your program's spec and know what you're doing

Spent a few hours tracking down a bug that caused half of the UI textures to suddenly vanish.
I finally wrote my own glDeleteTextures() wrapper ("myDeleteTextures") that logged all handles it was deleting and where it was being called from.
Turns out it was just *one* faulty glDeleteTextures() call that nuked three random texture handles. Repeat it often enough and eventually it hits something that's in use, and UI/font textures go boom.

This is largely true, although their distinctions lie with their support. Package managers, frameworks and libraries can determine how useful a language is.
>If I had to recommend one, I'd say start with C++, although many would disagree. Use codeacademy & torrent some paid courses. Or watch youtube videos. There are so many resources it's insane. One of the reason you don't really require a degree as long as you can show you're not retarded
I wouldn't suggest codeacademy/torrent/videos in general. Absolute C++ by Walter Savitch is my personal favourite resource for C++, as an important part to learning is applying, and the editions of this book give you somewhat challenging tests (though not as challenging as SICP is to LISP languages)
>I write automation software.
>My formula is simple;
>1. Market Research
>2. Determining if I can do it cheaper AND better (usually the answer is yes, especially if I'm competing with Asia)

Automation software is pretty big when it comes to job searching too, so this may be a useful formula to success, even if not doing it in a corporate environment.
>is this a good approach and what kind of earning power do you have with C++ skills?

Since no one else is replying at 3 in the morning, I have no choice but to turn to you.
You say snek and I googled around and all I can find is a busted meme from circa 2012. What is snek?
I've been browsing around ODesk and Upwork and its dominated by Indians and SEA Asians who already have arguably sturdy portfolios. As someone with literally 0 portfolio and coming out of the woodwork, should I charge 5-8 USD per billable hour to get started? Keep in mind I have a steady full-time employment that leaves me a lot of free time to tinker around.
And thank you.
>>54063772
thank you
should I learn C++ or python?
>>54063873
Neither
>>54063828
snek is Python
Whether you want to do a portfolio of paid projects, or your own personal free projects, you should work on constantly working and building a variety of interesting, possibly tough projects. If you can't get in paid due to indians and SEA asians, consider investing your time in just doing free work. For reference, I made that chip-8 emulator in C with python comiler+assembler, esoteric language interpreters, and synacor-challenge.com virtual machine in python, and that helped a ton getting a Python/Django job with 0 experience in webdev/django
>>54063845
No problem m8
>>54063873
C++ if you're interested in finance, games, or have a degree
Python if you're interested in scientific/mathematic research, webdev, or don't have a degree
Reason I mention degree is because if you have one, it's easier to get into C++, which will pay you more if you don't like webdev. If you don't have one, Python is still relatively easy to get into with a decent portfolio
>>54063887
when you say 'have a degree', do you mean a degree in CS? or any degree.
>>54063992

>>54063887
First of all, I would like to thank you very much for all the relevant information you are throwing my way.
Secondly, I understand you don't have a STEM degree as well, but was wondering if it was even a technical associate that you hold.
Secondly, I have been using java and javascript for backend database management and I would like to believe it has given me the absolute basics (loops, stacks, classes, etc).
I don't mind working on projects even full-time to jump start my career, but what exactly do I make? I'm someone who had to use scripts and programming maybe 15-20% of the time for "work" related stuff. I've googled around for beginner projects, but I feel that I would just grok a tutorial and produce a clone.
What would you recommend for someone with rudimentary Java to undertake, or should I just jump onto Python, learn that, and then focus on a project? I also have some basic on the job training for Spring Frameworks.

If you've used java/js for backend, you're pretty much set for getting backend job right now anyway if you can find one using Java.
>what do I make
What things interest you? What things bother you that you can do better? Alternatively, you may find inspiration doing coding challenges. synacor-challenge.com, microcorruption.com, hacker.org, codingame.com, and even hackerrank.com are all useful for teaching new things and providing ideas for unique challenges
If you're really into Java, learn Spring
If you want to try Python, that is also invaluable as Django is probably more popular than Spring

I guess I should have brought up that point sooner, but I am hoping to break into software engineering. Software engineering (if I'm not mistaken), seem to be much more hacking heavy than the other fields. I just feel stuck in a hole because at this point on my careerpath the only thing I can really aim for is to become a senior database administrator, since I lack the credentials to become a director unless my networking pulls a hail mary.
It seems that most people nowadays have 4-5 languages under their belt, and I was hoping to pick up snek as everyone is going on and on about how simplistic it is, even for those who have no background in code.
I guess the whole issue with me is, I want to become a codemonkey, but I have no idea what the hell I want to code.
I understand that my problem is more abstract personal issue rather than a technical issue, but any input from yourself would be appreciated regardless.

They're both the same, just that the latter is either dependent on company, or only after a certain time in some companies.

It just hides all the complexity from the user because everything is already made for you.

I did look into webdev slightly as per your suggestion, some job posting and youtube vids entailing the job duties, and it seems a little graphically inclined.
I guess I'm asking to see if a position actually exists where a manager/pm comes to your desk, throws down the project manuscripts, says "code all of this by x o clock on y date."
I apologize if I'm being super difficult to work with, but until 3 days ago I didn't even know my current job was considered in the computer science field.
>>54064288
No but it isn't terrible either. If you want a programming language that "werks" use it.
>>54064441
C++ gives you the tools, the complexity is as big as you want it to be.
C is harder only because the standard library is smaller and there is no STL (among other things like raw pointers, no exceptions, etc.)
>>54064399
Once you use operator overloading, it's not even nearly as useful as C since you can't wrap it in extern C for portability with other systems/languages
>>54064433
No problem
>>54064444
>and it seems a little graphically inclined.
It's not at all. My work, as graphics go, just involve the displaying of numbers or text. Excepting graphics, most of my work revolves around the back-end logic: changing models/objects, form validation, processing imported/exported files, etc

That was me you were replying to, and I'm just so bored of the monotony of entering fucking data into SQL servers.

The frustrations of fucking up a tiny bit of code and scrounging on stackoverflow for hours looking for the answers and then that huge feeling of relief when you don't have to rebuild messed up legacy code.
The other 75% of the time I'm plugging in info from PuTTY or Salesforce depending on what department is up my ass that particular day.

Indeed, that is also a plus. Backend web dev is almost like application development anyway since processing requests and outputting responses works almost the same way, except the responses are in html form rather than a window form. So if you really were interested in that, this is definitely at least a stepping stone, since it'll be easier to get into with your current experience

>>54064771
A prvalue of arithmetic, unscoped enumeration, pointer, or pointer to member type can be converted to a prvalue of type bool. A zero value, null pointer value, or null member pointer value is converted to false; any other value is converted to true . A prvalue of type std::nullptr_t can be converted to a prvalue of type bool ; the resulting value is false .
>>54064786
why would you want a null pointer to be an integral type? lmao
>>54064829
Them floating pointers
>>54064795
there is still the ambiguity about whether that false value was a pointer to 0, a null pointer or a null member pointer value, which is why the distinction is necessary. !_Component means what should be a nullptr is actually a pointer to 0
>>54064851
A null pointer will be converted to false, the only change over == nullptr is that on the few systems where it's different, you'll have an extra byte of memory at 0x0..

I've never done 3D programming before, and have barely any clue of the maths behind it.
Basically I have to rotate a 3D model.
However, how would I transform according to the viewpoint?
E.g. the model starts with its axis' aligned to the viewpoint. But when it gets rotated they get out of sync, obviously. Now, when I want to rotate it across the Y axis according to the viewpoint (after a previous rotation), how would I transform this matrix into something applicable to the model? Because rotating it across Y on the model will give completely different results.
I know this should be something really simple, but I never learned anything about it.

does anyone have experience with isolating pointers with scans? I have a variable I can manipulate that is a double or a float that I can't really isolate. There are a bunch of ways you can do pointer scans, right, but I sort of need to streamline this because every time the variable changes none of the values that come up were "it". Obviously integers are much easier, but it'd be really nice if someone knew anything

I've been wary to start learning android dev because it looks like a clusterfuck of complicated shit but now that I've started, I've got to say it's pretty easy.
>>54065490
Which language? C, C++, Java, Python or something else?
>>54065427
>>54065421
well basically to reverse engineer something or whatever you can search for pointers in a running process
you can actually change these around if you'd like, as I did in this image
the pointer I need to find has a value that is either a double or a float and so is very difficult to isolate due the program truncating everything past .01

If I should start programmig with C, why then many people say that C is bad for starting programming.
>>54065734
because they found it complicated themselves and want to meme you into Python and Scala
>>54065734
Probably because they expect everything to hold their hand the whole way.
C is a fine beginner's language. It's very intuitive and teaches you programming in a "bottom-up" sort of way.
Expect to make mistakes when starting with C. Making mistakes is the best way to learn.
>>54065747
>>54065734
languages are just tools
there's a very small set of things you need to do to 'know' a language, and once you know it in one language very well it translates pretty easily
some languages are well suited to different things, like standalone applications vs servers or whatnot but at their core they are all the same so all this shit about how hard a language is is really just confusing to me
programming isn't an art, it's a set of tools you can use to complete a task

don't get me wrong, you should definitely learn java first
it is very specific and for learning it's really great
I as speaking a lot more generally

>>54063094
KILL YOURSELF
>>54065899
Java preaches OOP as the only way to write programs, and beginners will fall into that shitty trap.
I would argue that OOP is actually pretty shitty overall, and is only suited to certain types of problems. It should be taught as a tool, not as gospel.
>>54065916
Did someone disagree with you?
>>54065921
it's literally the only good way to write programs. even in C you end up with a kind of cobbled together OOP.

Just to clarify, "structs and functions that work on those structs" is not OOP.
>>54065938
yes it is, the most basic form of OOP is just a syntactic sugar for structs and functions that work on those structs
>>54065911
you can also write in assembly and use structures everywhere

The entirety of SDL, the standard for gamedev, disagrees with you. Even if you say it's not a game in itself, it is a large C project

That's one of the things I hate about these sorts of arguments. OOP isn't even well-defined. There are all sorts of things that different people tout as OOP, but it's certainly a lot more than just a layer over structs.

Java is absolutely horrible, do not listen to anyone shilling Java. There's probably 1 or 2 guys max. Java could have worse performance, but it's not the end of the world.
Python is not a good language and the arguments for it are completely hollow. Python users will say "good for prototyping", "good for academia", "good for learning". None of these are true and are based on the flimsiest of evidence.

While the whole structs and layers thing does bear some resemblance to OOP, I agree that people should never be taught OOP like that, it just makes for really messy learning.
Just use the fucking concepts, everything is an object with attributes, and objects can be parents or children of other objects, which means they get to share some of the attributes, that's it

I know you'll hate this questions guys, but I'm stuck in a job I really hate and I'm looking to get into programming for that reason.
My question is the following. If, in 2016, you had to pick a language/framework to get from zero to employable as a freelancer, what would it be?
I live in a rather cheap country so even if I made $10k a year would be enough to quit my current job.
(It wouldn't be from zero really, I already understand concepts such as for loops, pointers, what "object oriented" means etc. when I was a kid I learned Pascal and even won some national tournaments for young programmers)
I'm thinking Ruby+Rails would be one option, another is just going full Javascript and node JS
