The under 100 line challenge!

[OronDF343]

My first Haxe program (learning it for a course)

It's a file shredder - drag files and folders onto it (or specify them in the command line) to shred them

It does 10 passes of pseudo-random data (no renames)

package;
import sys.FileSystem;
import sys.io.File;
import sys.io.FileSeek;

class Main
{
	static function shredFile(s:String):Void
	{
		Sys.println("Shredding x10: " + s);
		var fr = File.read(s);
		fr.seek(0, FileSeek.SeekEnd);
		var l = fr.tell();
		fr.close();
		var fw = File.write(s);
		for (w in 0...10)
		{
			Sys.println("Pass " + (w + 1));
			fw.seek(0, FileSeek.SeekBegin);
			for (i in 0...l)
			{
				var r = Std.int(Math.random() * 256);
				fw.writeByte(r);
			}
		}
		fw.close();
		FileSystem.deleteFile(s);
		Sys.println("Deleted");
	}

	static function main():Void
	{
		Sys.print("Press any key to begin shredding...");
		Sys.getChar(false);
		Sys.println("");
		var q = new List<String>();
		var dq = new List<String>();
		for (s in Sys.args())
			q.add(s);
		while (!q.isEmpty())
		{
			var s = q.pop();
			if (!FileSystem.exists(s))
			{
				Sys.println("Path not found: " + s);
				continue;
			}
			if (FileSystem.isDirectory(s))
			{
				Sys.println("Found directory " + s);
				dq.push(s);
				for (f in FileSystem.readDirectory(s))
					q.add(s + "/" + f);
				continue;
			}
			shredFile(s);
		}
		for (d in dq)
		{
			FileSystem.deleteDirectory(d);
			Sys.println("Removed directory " + d);
		}
		Sys.print("Finished. Press any key to exit...");
		Sys.getChar(false);

Had to calculate SEM and mean for a bio assignment. Since I was given a pdf with the numbers, I decided to quickly write some java code to do it for me instead of trying to enter in all the values into a calculator. It's not pretty but it works and it's under 100 lines! I apologize to anyone that's going to try and read this as I didn't comment it and it's probably terrible since efficiency or appearance came second to getting this done quickly.

It calculates pi by measuring the area and diameter of itself.

Go see in action at Shadertoy. I'm planning on rewriting it in C++ and with global illumination, so I can print it on a business card.

Over the last couple of days, I took it upon myself to learn Python.

I'm used to C# and a little JavaScript, so I thought this would be a nice thing to try out.

 

I created a sinusoidal wave script that allows the user to enter text, choose whether or not they want it rainbow coloured or black and white, alter the wavelength and all of that jazz. And it took a little while, but I managed to suss it out.

I've probably broken a billion conventions just to get this under the 100 line limit, but if it works, it works. And having tried it, it works for me.

I doubt I've ever actually written a useful program under 100 lines of code.  I was thinking about posting a college and friend's code however. Which is a Java application which doesn't use the Google Maps API, and converts an address into coordinates using the harversine formula.   

 

Other than that, I wanted to say that some of these are fantastic and are great ideas in under 100 lines! I think I'm going to try and work on a network monitor or something.  But that's only if I can make one useful enough at under 100 lines.

I'll have to rewrite my prime number sieve and submit it to this. I used some pretty serious optimizations to get it to run actually decently fast.

Why not Eratosthenes' Sieve? In practice it's faster.

So I wouldn't know how to do this but I imagine pygame could be useful, just to detect inputs.

Simple .NET C# Sieve of Eratosthenes. Decent practice. I'll update it later to make use of classes (class for sieve generator, one for counter, one for summing... whatever) The attached file is a .doc file with the correct syntax highlighting.

Hmmm...

#include <bits/stdc++.h>
static const int N=0x989680;
bool v[N];
int main() {

(N is 10'000'000)

I much prefer look up tables.

def is_prime(n):
    data = {'numberInput': str(n)}
    return requests.post('http://compoasso.free.fr/primelistweb/page/prime/liste_online_en.php', data).text.find('>{}<'.format(n)) != -1

N <= 1,000,000,000,000

Someone has to understand how the lookup tables are generated so that there can continue to be lookup tables!

Decided to do some Python for a bit of automation stuff on servers, and I made a library for multi-segmented downloading from FTP servers. I don't really know Python so let me know what I'm doing wrong. https://github.com/MarkPash/pash-ftp/blob/master/pash_ftp.py

Emulates a toggle switch with a momentary switch

 

int buttonPrev = 0;
int state = 0;

 

while(true)
{
    if ((button != buttonPrev) && button != 0)
    {
        state = !state;

Hey,

 

Powershell script i quickly wrote for a client school. Their SMS system does not create students automatically and they use Google directory sync and google password sync to sync users into google apps.

 

The script can be improved greatly and will be when I can be bothered / have time.

 

The script will import an CSV with all the student information, First name, last name, email address and password etc, the default user scripts are currently hard coded in the script. script base config can be changed with a config csv that lists the domain name, creation OU and a few other details.

 

The script does the following

 

1.  Imports all details required for user creation
2. creates all users from csv into the OU listed in the config csv
3. creates the user a home drive for folder redirection
4. gives the user modify rights on said folder
5. syncs google directory sync(runs as another user due to how we have their site setup), waits for sync to complete
6. resets user password to what it was in the csv to force google password sync to sync
7. script outputs to a log file for basic debugging
8. renames the user import csv to the date and moves it into a old folder
