how do you build up stamina? I worked for the past couple of days on my project and now I'm exhausted (despite 10 hours of sleep, modafinil, coffee) and don't want to do anything but shitpost on 4channel

You're addicted to caffeine and you probably have depression on top of that.
You can't build up motivation when you have depression.
For now, just lay off the caffeine and drugs for a week or two and see how well you do.

>10 hours of sleep
10 hours of sleep means something is wrong
> modafinil, coffee
great way to crash after

Work around 4-6 hours a day tops.
Socialize, exercise and go on walks.

last night; couple of days ago I had only 5 the night before and somehow managed to push for 12-13 hours of work, didn't feel tired at all, just worked
today I maybe wrote 20 lines in about an hour

There should be two - one for the whole app (it's in the gradle scripts directory) where you will be adding application level libraries/dependencies (like kotlin) and the other one (in the app directory) for the main module where you will be adding libraries and other shit. The third one is probably just a copy of the seconds one.

how to into making code generation tools
tired of the C++ committee being slow as fuck and would also just like to automate some shit

i've fiddled around with using clang/LLVM as a library but its documentation leaves much to be desired
it's not that everything isn't documented to an acceptable standard - it is (frankly it's rather well done) - it's that clang/LLVM's architecture is extremely complicated and interconnected
the documentation is almost useless without a structural overview of what does what when and how
which sucks because it was made to be used as a library and it appears very well designed

does anyone know if there's some kind of detailed architectural information on clang/LLVM
or if not, are there any easier alternatives to clang/LLVM for creating code generation tools

You need to take frequent breaks. Set at least 20 minutes aside each day for stretches and light aerobics.
Before you go to bed, do something mindless and fun, like a video game or a funny anime.

What kind of a shit university has girls?

>I can't with conditionals...
Just think what Jesus would do, given some input.

State universities

Having girls is important for the work/study space. They can provide eye candy and emotional relief, like cats or ping pong tables; plus, they can boost morale by making the real workers feel smart/useful when helping (or simply talking to) them, to counterweight the real discussions with professionals they have to go through throughout the day

That's a bit selfish way to think of it. What of the girls themselves? What if their brains overheat?

Yeah but I mean real university-level programs.

You can't expect of them to be able to make that judgement, so it's unfair to cast the blame on them. The husband should be held accountable in case of any misfortune for mismanaging his woman.

My university is full of roasties, but only the ugly ones come to the CS classes

i know i don't exactly need to be touching llvm a whole lot right now, i just figured clang/LLVM was more semantically correct

my issue is i don't really know how to go from traversing, matching, and visiting the ast to actually generating code
I've had a look at the clang based implementation of qt's meta-object compiler, as that's closest to what I'd like to make, but it left me confused.
the individual pieces of how it works are pretty easy to understand, but I don't know how they all fit together

My web development course had about 200 students, ~50 % of them females. My compilers course had 20 students, all of them men with big bushy linux beards.

lol fucking no
100% male work environment or it's terrible
Women make everything worse

Your compiler course wasn't mandatory?
>tfw I didn't have a single webdev class

Post on 4channel less.

After a while of really getting into your work/projects, you come back here and realize how low-content and time-wasting this place is. You will check 4channel, realize how insubstantial arguing with idiots is and you'll want to go back to being productive right away

Even /dpt/ is just language wars nowadays, sadly.

Also take adderall instead of modafinil. Smoke weed to take the edge off of the stims at night.

Not for my major. I studied machine learning. It probably was mandatory for software development majors, though.

POO lovers praise it as a pinnacle of POO, I want to know what's that about

Start with a small/simple AST, like one that only supports a print statement and literal operands, and then gradually add features until you're comfortable with the concept
You might need to throw out your work at some point if your architecture doesn't let you support more advanced features (closures, coroutines, whatever) but the point is to practice and get over the hurdle of "I don't know where to begin"

One of my classes had a Chinese girl who looked 12

Damn right. I can descend gradients you wouldn't even believe.

You make a recursive descent parser that produces an ast. You then translate the ast into Assembly. You then have a working compiler. Next you write an optimizer to modify the ast. If you get good enough and want to make a compiler for a very specific use case language very quickly you can tokenize with regex and parse straight into Assembly and have a working programming language in a few hundred lines of code. But if you want a monster that’s gcc/clang tier you need an ast and optimizer.

>no Java POOP
Shit taste

Not everyone is into regression. Some prefer classification.

My cousin is going to a bootcamp or something to learn coding, he wants to become an ethical hacker. He was over at my house, needed to use my internet but I have automatic ip assignment turned off, and he had no idea what I meant when I told him what ip and gateway to use. He's 29 btw.

Classification is just regression interpreted as probabilities.

have you tried ethically hacking his boy pussy?

Hopefully the Xilinx 7 series bitstream is fully reverse engineered soon so that I can make my own HDL for it.

willing to do someone's programming homework

I need a program that can take the description of an arbitary Turing machine and tells me if it'll halt for some input.

could you simplify this for me? I feel really stupid right now.

if Position == 1:
TextString = 'Example Text'

if Position == 2:
TextString = 'More Example Text'

if Position == 3:
TextString = 'Even More Example Text'

put them in an array

change the ifs to else if
otherwise perfect

Woke up at 2pm due to being up all night with back pain. Didn't go to work. Popped some drugs and now I'm on my seat. Pretty much just writing some logic to write to a database and scoping out requirements for other teams.

it would cost me less time if some people weren't on my team
and by some people I mean one person
fucking global variables everywhere
5 layers if if and elses

>taking up more memory
why user?

Don't really see a way to "simplify" it further, but you can change its form by using a switch, or else loading it into an array.

Help a retard out, trying to do a shitty calculator junit test, but can't figure out the test.

@Test
@DisplayName("negsqr")
public void testSqrtNegative() {
calc.squirt(-4);
assertEquals(???????);
}

Should it be assertThrows, since the calc throws:
if (n

in something like C or C++ that wouldn't take up more memory

I don't know C# but you're not closing the connection after the send, so your receive is just sitting there waiting for more data. You have the broadcast in the bytes buffer but you're still waiting for receive to return.

You could do something like this, but I don't really see any problems with your solution.
pos_to_text = {
1: "example text",
2: "more...",
3: "even more...",
}
text = pos_to_text[Position]

Wait never mind, the documentation seems to imply receive returns after it gets a datagram.

I think it's because you're not specifying the port in your client. You have to send the datagram to the same port that the server is listening on.

Does that work?

What a shame, I always wanted to be a webdev. Actually I'd rather kill myself, thanks though.

You could use a switch statement but it would likely compile to the same thing here.
