I've commited code changes to a remote git repo from one machine, while another machine has some local uncommited changes.
How do I pull in the commited changes and keep the uncommited ones? (except for creating a diff file and applying it after pulling)
>>53985855
Figured it out: stash, pull, stash pop. Not the most ideal solution, but it worked.
Here's a nice blog senpai
I've ordered two books about C and C++ and back in school we were taught very basics of programming. But I don't really know what I'm doing yet. Also, 5 years ago or so when I was a kid, I programmed some OpenGL renderer without knowing what I was doing, but it seemed fairly simple so I think I can do it if I try
I want to do graphics related programming (3D), do you have any tips on getting started at a nice pace? I'm planning on programming a simple game ''engine'' for iOS so from what I understand, I should achieve it with Swift and Metal or am I retarded? It's true that I don't even understand how this really works
>>53985632
but that's valid...
>>53986018
C++ and opengl would be more versatile (less platform-specific) than swift and metal, and swift isn't very fast or good from what i've heard about it, and you can transpile from glsl to metal

>>53986041
All of them are valid, but none of them are good:if x:
return True
>>53986057
return x
you idiot
Why isn't my code working?
int arr[) = new int[100]
for(int z = 0; g <= arr.length-5;i++)
{
arr[z] = z;
}
int moo = 0;
while(true)
{
System.out.println(arr[moo]);
moo- -;
if(moo == 1)
{
destroy(moo);
}
}
}
>>53986041

oh but that's not the language you autists like

>what is an early return
FUCKING RETARDS
>>53986122
>if(x) return x;
is fucking retarded stupid shitkid, it should be return true
>>53986122
Why? I mean, if that code is the whole thing, then sure, usereturn xjust to save a few bytes.
But if you add some more code, then returning a bool instead of a variable is easier to figure out at a glance.
>>53986018
you will give up once you realize how difficult it is to make an engine and how much work it requires to make a fully functioning good one
>>53985981
iirc, that is actually the ideal solution. It's why stash was made.
>>53986093
>>53986103
You're a fucking retard, the code implies he doesn't want to return from the function if x isn't true.
Kill yourself, pajeet.

He's right, though.
Making a basic engine is pretty hard.
Making an advanced engine that does what you want it to is suffering. You need some sort of autism and tons of free time to accomplish this.
>>53986235
It's true making an engine is something only a professional experienced programmer with many years of experience can make not a guy just getting two books on it you pleb

He's right though. 3D graphics programming is a pain in the ass all on it's own, and programming an engine can be complicated as hell. Then doing it all for a mobile phone with limited resources? WHILE learning a new language and framework for graphics? Come on, man. It's a recipe for disaster or severe burnout. One step at a time. If he actually did want to just program a game for mobile, he probably should just use something like unity.

Depends on the program. If you need to squeeze a lot of performance out of the hardware, you need to think about that stuff a bit. Otherwise not much.

Pretty much never.
The main form of optimization you'll be doing in any modern, high-level language is just sanity things.
Simple example: rather than opening the same text file on each iteration of a loop, just open it before you go into the loop.
Basically doing expensive things a minimum amount of times.

hello i recently moved to linux and i'm having trouble finding a text sorter. i used a program called CLADIRON on windows but it's freeware and will likely never be linux. i asked in /sqt/ and they said a bash script could do what i wanted
basically i have a text file with stuff likeandrew,hello100,bye
mark,hello200,bye
lauren,hello300,bye
bob,hello150,bye
and cladiron would let me sort the lines based on the number in the second part, but i can't figure out how to do that with just bash. specifically i dont know how to iterate through the first part since it's not always the same length.

I am pretty much pulling these numbers out of my ass.
>>53990582
That's better than half of the beginners in /dpt/.

>What's written in the console is misrepresented (>>53990404).
only slightly. What she did write is equally bad. Don't get bent out of shape because it's not a character per character representation.
>It is when the console is not the point of the image
It's the entire point of the image. The fact that she's using and IDE isn't even important. She using this photo to advertise her "girls coding club" program, and she's filled the console with retarded shit. Does that fill you with confidence that she is either a good programmer or should be running a coding club?

why does a beginner have millions of followers on her koding twitter account?

I leave 4chan for a few weeks and always come back surprised to find so much shitposting.
Do these people even notice the water they're shitting in?

I came up with the idea and started writing an automated tool at work that basically converts stuff from database into code. I'm only on my first year there, and an older employee who's been there long time who I told my idea took it, did it during the weekend and took all the credit when he showed it the next week.
Didn't even mention me.
Fuck my life. What do.
Never ever do anything extra at work, only do the bare minimum?

That's 100% dickwaving and isn't really worth much for others to know, so the "silly things" like language semantics and algorithms discussions are actually the only "relevant" content here

Just because you say something doesn't make it fair.
>>53990767
also talking about actual projects on dpt isn't easy. If you're working on something more meaningful that a college project, it's not something you can really talk about easily. Also if it's anything big, it's something you work on for weeks and months and there's not a whole lot to say about it.
I'm working on a big personal project in F#. Hoping to make some decent cash on it. But i've mentioned it a few times in months gone by. No point bringing it up often.

>What she did write is equally bad

>It's the entire point of the image.
No it's not. She posted to show that she's working on code. Ignoring the code and nitpicking over the console (while misrepresenting it) is being autistic and missing the point and trying to create drama.
>Does that fill you with confidence
She's not an instructor. She just motivates people to get interested in the topic.

Exactly. In conclusion, /dpt/ really isn't for project discussion. I'm starting to write a compiler for my language (I hope) but I'm not gonna talk about it outside of this post ever
>>53990806
But it is fair.
>>53990825
Tell me. I'm interested in hearing about bigger projects. What are you making?
In C if I have an array of structures that each contain a char pointer set to a string, how can I access an individual element of the string with pointer notation?
keytab[0].word[2] works to access, say, the 3rd letter but keytab[0].word+2 and keytab[0].*word+3 don't work.
>>53990831
>It's literally something everyone has done.
yes, but not something we expect our teachers to be doing and then posting pictures of them doing that on their social media because they don't even realise how bad it looks.
If she was just learning (which she obviously is) fine. But the whole point is she's marketing her KodeWithKarlie program. That's why it's depressing.
>She just motivates people to get interested in the topic.
>Motivates other women to code. Can hardly do the very basics herself.
And this is exactly why people find this depressing. The whole thing is called "KodeWithKarlie".
>>53990846
>What are you making?
It's a desktop tool. Already used by a lot of people. Trying to add more features and commercial it.

Beginners start at the beginner level. This isn't some kind of radical discovery. Normally people don't care at all and go about their lives. Autists shit their diapers because she's not doing recursive algorithms and fixed-point theory from day one.
new thread?
>>53990902
Come on, I got genuinely interested, atleast tell what it's meant to do. Also can you share it since other people use it too, I'd like to try?
>>53990644
There's a picture of her with a ruby hello world example code copied line for line but I can't find it. It's the one with all the fruit in it.
>>53990964
Not going in to detail. I don't want people looking it up and learning it was written by a 4chan shitposter. I can talk about stuff that won't help identify it. Ask away.
>>53990964
Also, as I'm interested in commercialicing one of my bigger projects I'm really curious how you got the initial traction of users. Did you market it already somehow?
>>53989001
>>53989021
Okay, guess I didn't think of that.
I imagine that would hurt performance considerably in some situations though.
>>53990915*(keytab[1].word + 2)works.*(&keytab[0].word + 3)gives me a letter that's not even in the word.

>Beginners start at the beginner level.
That's fine. But she's meant to be motivating other women to learn to program, she's the head of the entire program, and it's not something she ever bothered to learn herself.
What if you saw some guy who was trying to motivate more people to code, who was saying shit like "yeah, it's really fun and creative and motivating. Yeah, it's empowering. Yeah, believe in yourself, you can do it!" and he had never done any programming in his life. Either because he couldn't give a shit, or he found it too hard or both. Would you find him a very compelling person to listen to?
>>53990955
Either you just skipped over everything that guy said, or you're fucking retarded.

It was free initially. And a lot of people use it now. It gets about 6k downloads a week. So now I'm adding more features and working on a way to charge for those new features.

>Implying gamedevs need low-level programming
I know asm and stuff but if I want to make a game I will use Unity because I value my time. Also you can use C++ and asm in unity if you know what you are doing.

>>53991079
>She's obviously in the process of doing so.
yes, which implies she didn't know anything before she started this program. Are you understanding it yet? You also ignored everything else I said. I presume you know I have a point but find it too painful to accept.
The reality is women in general make shit programmers. A reality made even worse by some of the highest profile women trying to get girls to program can't even bother to learn even the basics themselves on their own time, and are only doing it because it's topical right now.

anyone got a good project for someone beginning with x86 assembly? I just did a square root program, so something roughly that size
