## Main Loops and listeners in live coding systems

My question is about the construction of main loops running in the background listening to commands and signals and how are they constructed to be efficient. For instance in live music synthesis programming languages like SuperCollider or PureData, you have somewhere a sound server waiting for changes in your source code and applying changes immediately to your program. Are these things like simple `while` loops running for ever, waiting for updates in the environments. Running a simple `while` loop in python will consume more than half of the CPU, so this can surely be not done. Can any one give me some hints?

## How much time should be dedicated to learn coding as a beginner?

Java and HTML are the two codes im willing to learn, but as well as get myself familiar with them as well. Is there a certain amount of time to understand the fundamentals well enough to have dedicated time for practice?

## Coding practices related to logic within function calls and conditional statements

I recently started working as a programmer and I am currently going through some codes (in C#) written by my colleagues. I have noticed that they tend to include logic within function calls within some conditional statements. For example:

``if (MoveSpace(currentPos, distance * time)) { doSomething } ``

They would also include logic when determining array positions. For example:

``Space currentSpace = array[a*b, x*y] ``

Is this a good/bad practice? Would it be better if I create a new variable for these logic results and pass in the variable instead? Thank you.

## How do I construct a NTM that accepts the language consisting of the coding of turing machines that halt on one input?

I currently have a problem with the following question:

L is a language consisting of the coding of turing machines , that each have an input w they halt on in at least |w|^3 steps. I need to construct a NTM (Non-deterministic turing machine) that decides L.

My idea was to simulate every possible input <= |w|^3 on a given turing machine M, by using a separate band in my NTM for every single input word. If there is one band where M halts, then the NTM accepts.

Is this the right way to go about it? My problem is, that I don’t see why I would need a NTM to decide L, a standard turing machine would be able to do the same thing.

## Create a URL to post data to google sheets WITHOUT WEB CODING

I am totally new to coding and web and Java, HTML, and everything so if the answer exists please redirect me, otherwise pleas help!

I am using a digital signage software with Google Form and spreadsheets and it used to work just fine. But Google is updating and now some features are not working anymore so I need something new that does work and keeps working.

I need a URL that when i click a button in my digital signage (it is a touchscreen (windows OS)) that it sends data to a Google Spreadsheet (there is an option in the software where I can input a URL). But I have no access to any website so I cannot use any coding. I have watched hundreds of video’s and read a thousand forms but nothing comes close to what I need.

The data that needs to be sent: A row with the time that the button was pressed,a preset name and a preset number and a text box (where they can write names and stuff).

To answer a few question I can imagine you have:

• No I do not have access to a website and I never will. (the company won’t give away login codes or pay me for a second website only for coding)
• No I have absolutely no coding experience so any pre-written code would be greatly appreciated!
• The DS software is http://www.digitalsignage.com
• The only tools i have available is google. You can do a lot with app script and google API, but still totally new so a video or pre-written step by step, or pre-written code highly recommended!

Any questions more than welcome as well as answers!

## Cyber security and coding [on hold]

I started to play around with Kali Linux, nmap , metasploit, lately and although it is interesting it so far it was much about applying scripts. So my question is, is there a field in cyber security where you really have to code our own stuff (exploits, etc) or is it mostly about applying scripts?

## Should I be using the numpy library or should I be coding the algorithm from scratch without using numpy?

Im currently trying to learn how k means clustering works. And there is a numpy function `numpy.linalg.norm(x-y)` that is used to find the Euclidean distance between two points. I was wondering if i should be using that or should i be writing a function to calculate the Euclidean distance myself?

## How do I use more coding techniques to shorten my text game code

I recently started coding and after learning a bit about functions and basics I tried to make a simple text escape room game. My code is working and the game functions as intended but I now there are probably neat ways to reduce the long amount of code using techniques I haven’t yet heard about. I would really appreciate it if anyone could offer some improvements I could make.
