excellent post

I'm finishing up an android app, and I've reached the point where everytime I want to publish it, I decide I want to add one more feature. I think I'm just worried if the first release is missing "feature x" then people will pass over it or rate it bad

Does anything in university ever actually get seriously difficult?
I just got into algo/data struct and we've already built simulated multi-level caches and round-robin CPU schedulers, which I'm sure would be much more difficult to implement on the OS level but as an exercise were...not hard, at all.
I keep expecting "the next class" to be where it gets real and interesting, but class after class is just "oh so that's how you do that" followed by no critical thinking for two weeks.

Is there a language like C that doesn't require me to spend hours trying to get libraries from 20 years ago to work?

inheritance was a mistake

>>61295761

>>61296028
You're making a mistake if you're in a situation where you can choose what you can use and you chose 20 year old obscure libraries with compatibility that you can only download off geocities backups on archive.org

It's not C's fault that you're straying into the woods and getting cuts on your legs. You can do that with any language.

>>61296113
Enjoy your single threaded pile of garbage

You should go back to Python, C is not meant to be used with your import addictions.

I can taste how upset you are from here.
C is not a language where you run around and import 30 libraries to do what you want. If you're working in C you're almost guaranteed going to have to write most of it yourself.
I know that's not the answer you want to hear because boo hoo, now you have to work! But that's the reality of the language.

Shit programmer here.

So I'm extremely unfamiliar with android studio and I haven't touched Java in forever.

I'm trying to create a color changing like stop light button that takes in a click, then pauses, before turning to the next color.

Basically how I have it is

//Stop is the Button from my MainActivity.xml file
Stop = (Button) findViewById(R.id.stopButton);
//(onclick class)
Stop.setBackgroundTintList(getResources().getColorStateList(R.color.Red));
try{
Thread.sleep(5000);
//Pausing the thread for 5 seconds
Stop.setBackgroundTintList(getResources().getColorStateList(R.color.Yellow));
Thread.sleep(5000);
Stop.setBackgroundTintList(getResources().getColorStateList(R.color.Green));
} catch (InterruptedException e) {
e.printStackTrace();
}

But this basically ends up with Thread.sleep for the time, but the actual Tint change never happens. It's just sleeps for 10 seconds. Is there (obviously) a better way to do this, or some method more specific to AS for handling Activity pauses/breaks? How do I pause the activity for 5 seconds, do a tint change to the button, then continue on?

Of course the fag being so hostile to an anon working with assembly is a jscuck. I bet you're also the fag who can't comprehend "apt-get install libxxx-dev" and "./configure; make; make install"

This is a program written for a university assignment. INb4 "not doing your home work for you", I've already completed it. Could I get some meaningful feedback? The TA who grades these "doesn't like to type" and just gives out 100's or 0's.

I know there are a multitude of things that could be done better, but I'll never be able to fix them if I don't know what/where they are.

I'd bitch to the professor AND administration anyway for only giving 100s or 0s on essentially an essay assignment.

It's really minmal. you have 2 regs (one Accum, one GP), a stack and basic arithmetic ops.
SW swaps the contents of the two regs.

>>61296528
No It is. It is self reliant. It has access to real mode and is written in a language that can use constructs of Machine language necessary for an OS.

Do you live in some sort of alternate universe where people care? The administration doesn't care. The professor doesn't care.

The TA "Just took the class semester" and "doesn't like typing".

When do you realize that you got comfy with your language? Is it when you start using it to automate your personal tasks?

C is for systems programming and things that require super high efficiency. if you want numerous easy to use libraries that just werk and which you can copy-paste together, C isn't the language for you. if you're making a desktop application use java or something. no one hardly even uses C anymore so why are you even using it?

What you are paying for is the diploma certifying that you know this. If you just needed to learn something for the sake of learning, you could reasonably learn a lot more for cheaper with a couple of textbooks and the Internet... although you would not have the environment of having an actual professor to talk to and bounce ideas off of.

As for why it costs so much... the reason is that because the government is guaranteeing everyone's loans, and because everyone feels that education is a must regardless of the cost, tuition costs are allowed to balloon with no end. If you can raise the price of a good, and the number of customers does not decrease proportionally so that profits drop, then it is always a smart move to raise the price. Basic supply and demand.

You shouldn't install signal handlers in libraries. I think the best approach is to provide a global cleanup function and let the main program invoke it when it terminates.
But you'll want to make sure that main program also masks signals during the initialization, to avoid the possibile race conditions.

Changed it to a runnable, and used postDelayed for the timing method and it seems to work. I got this to work with one Stoplight (or button), so now I want to try and get it to work with multiple buttons. I was thinking interating through an array or list of 3 values to switch between the buttons but I'm unsure how I would get the timing to work for it to delay between each three buttons, since it will just iterate through the list without the pause and all the runnables will start going at the same time.

Can someone settle this for me; does Java have unisgned int's or not? One person says yes, one says yes but they're objects not primatives and someone else says no.

Hey /dpt/, long time no see.

I was wonder what you all might think about my new compression algo. The objective is to minimize transmission length.

The algorithm is very simple:
1. Find the data you with to encode in the digits of pi.
2. First transmit the position where the data begins, then transmit the length of the data.

Here's an example:
The data I wish to transmit is "12345678"
So, I find this sequence in pi, and then transmit the location of that sequence, followed by 8 - the length of the sequence.
Thus, I transmit 186557266, followed by an 8.

What do you guys think?

>>61298698

It's based on an unproven conjecture, so it may or may not halt, and it's average compression ratio assuming the conjecture is true could be conjectured to be 1 over n!

>>61298704
not proven to work

>>61298801
>>61298843
To speed it up, I'll make it lossy, and just find the first sequence that is a 70% match.

>>61298892
also not proven to work
if the start is > than the size of the data you wish to compress, you've not compressed it at all

>>61298892
That really boosts the compression ratio from 1/n! to (0.7n)/n! In some use cases that could be a millionfold or more compression savings!

Reminder that "computers" are an object oriented imperative mutative nonfree bloated slow poo in the loo LIE!!!! Built on the pure functional stateless truth of more general logic circuit design. Electrical components are the perfect physical implementation of lambdas. Unfortunately they aren't first class -- you can't send a component as an electrical signal between other components -- but you can compose them, map them, curry them, fold them, and so on. Processors are a LIE! You do NOT need a CPU, or even an ALU, to do extremely efficient high level functional programming that runs MUCH faster than what passes for a """""computer.""""" Just grab some copper wires and a soldering iron, "write" your program, and hook it up to a battery.

I'm working on homework and I'm stuck, could someone assist me?

 During the tax season, every Friday, J&J accounting firm provides assistance to 
 people who prepare their own tax returns.
 Their charges are as follows.
 
 a. If a person has low income (<= 25,000) and the consulting time is less
 than or equal to 30 minutes, there are no charges; otherwise, the service 
 charges are 40% of the regular hourly rate for the time over 30 minutes.
 b. For others, if the consulting time is less than or equal to 20 minutes, 
 there are no service charges; otherwise, service charges are 70% of the regular 
 hourly rate for the time over 20 minutes.
 
 For example, suppose that a person has low income and spent 1 hour and 15 minutes, 
 and the hourly rate is $70.00. Then the billing amount is 70.00 * 0.40 * (45 / 60) = $21.00.
 
 Write a program that prompts the user to enter the hourly rate, the total consulting time, 
 and whether the person has low income.
 
 The program should output the billing amount. Your program must contain a function that
 takes as input the hourly rate, the total consulting time, and a value indicating whether 
 the person has low income. The function should return the billing amount.
 
 Your program may prompt the user to enter the consulting time in minutes.

What I'm having a problem with it where it says,
>For example, suppose that a person has low income and spent 1 hour and 15 minutes,
and the hourly rate is $70.00. Then the billing amount is 70.00 * 0.40 * (45 / 60) = $21.00.
I'm an idiot, how do I apply this formula to my code? Everytime I enter the hourly rate at 70 and the time at an hour and 15 minutes, it returns either 28.
For one thing, what the hell is the (45 / 60) for? Did they subtract time by 30 for some reason? Please help me out here.

That's a lie. Combinatorial logic is only inferior to a Turing machine insofar as those of its features used to implement one are concerned.
