Just write all code next to each other?

Hi

Totally new here but thought I would join the programmer master race.

Here is a converter that takes any US measurement (like feet or miles) and converts it into inches, feet, yards, and miles and displays them all to the user. Its really useful to do quick and easy conversions. It could easily be adapted to metric also.

I could not help my self into making that unit converter smaller.

Spoiler

import java.util.InputMismatchException;
import java.util.Scanner;
public class UnitConverter {
	public static double inches, feet, yards, miles;
	public static void main(String[] args) {
		Scanner Keyboard=new Scanner(System.in);
		String again = null;
		do {
			try {
				System.out.println("Enter a number: ");
				int num=Keyboard.nextInt();
				System.out.println("Select the units. 1=miles, 2=yards, 3=feet, 4=inches");
				int unit=Keyboard.nextInt();
				miles = (unit==2) ? num/1760 : (unit==3) ? num/5280 : (unit==4) ? num/63360 : num;
				yards = (unit==1) ? 1760*num : (unit==3) ? num/3 : (unit==4) ? num/36 : num;
				feet = (unit==1) ? 5280*num : (unit==2) ? 3*num : (unit==4) ? num/12 : num;
				inches = (unit==1) ? 63360*num : (unit==2) ? 36*num : (unit==3) ? 12*num : num;
				System.out.printf("Miles: %f \nYards: %f \nFeet: %f \nInches: %f", miles, yards, feet, inches);
			} catch (Exception e) {
				if (e instanceof InputMismatchException) {
					System.out.println("Please enter a valid integer number!!!");
				}else{
					System.out.println("Unsuspected error occurred contact R2D2!!!");
				}
			}finally{
				System.out.println("Again? (y/n): ");
				again = Keyboard.next();
			}
		} while (again!= null && again.toLowerCase().equals("y"));

Opens a random file of a type specified on line 12 (I have mine set to video formats)

99 lines with a lot of trimming, but nothing too egregious.

 

There is one nested ternary return statement in line 77 that is less than beautiful.

 

Usage: Put it somewhere you want to keep it, run it from there. Give it admin rights to create the context menu item in the registry.

Right click a folder with some video files, "Play Random File", and it will open it your default media player.

Does a program count as useful if it crashes the hard drive and makes it unbootable? If so I have an idea using bitwise operators to basically flip all the bits on somebody's hard drive.

I've just started programming in Python properly in the past 2-3 weeks (I started looking at Python 2 years ago) and I've created this...

Gold Box is a text based game where you have to locate a hidden box full of gold.

[marten.aap2.0]

I made this script a while ago. it rewrites number to the scientific notation (like 5,43*10^5).

The language is AutoIt3

 

$in1 = InputBox("Input","Enter a number you want to rewrite","Enter number")
$out1 = $in1
$out2 = 0
$repeat = True

While $repeat
    $repeat = False
   If $out1==0 Then
       MsgBox(0,"error","can't be 0")
   Elseif $out1>=10 Then
       $out1 = $out1/10
       $out2 = $out2+1
       $repeat = True
   Elseif $out1<=1 Then
       $out1 = $out1*10
       $out2 = $out2-1
       $repeat = True
    Else
       MsgBox(0, "New number", $out1 & "*10^" & $out2)

Good morning,

If you use a language like Java, you could just type out the program on one line, the compiler would understand it, but it would not be readable.

Wrote a shell script for doing a dropbox-style SSH-based RSync on a specific directory. Manual invocation, but when it runs it does an incremental diff on the files on both sides and moves the ones that were created/modified.

#!/bin/bash
#Server parameters
server="10.0.0.1" #Change this to your server's IP address
username="jim"
portnumber="20" #Your SSH server's port number.


#Excluded files
#I added an example excludes file based on files I've had problems with in the past.
path_to_excludes="...../rsyncexcludes.txt" #Change this to the path to the excludes file

#source and destination
#Please note that due to the nature of rsync, these MUST be absolute paths. They also
#must match on the source and destination, so if you mirror /home/joey/SyncMe on one
#machine, you'll get /home/joey/SyncMe on the other.
source_path="/..../SyncMe" #Path to what you're syncing plus the folder name itself
dest_path="/..../" #Path to what you're syncing without the folder itself

#Tools
excludes="--exclude-from $path_to_excludes" #if you prefer to hard-code exludes, use this variable instead of the excludes file
sshcommand="ssh -p $portnumber" #This is the SSH command. If you need extra params to login, place them here

#From here down is the code to sync stuff itself. Most of the params should be above.
rsync -avucr $excludes -e "$sshcommand" $username@$server:$source_path $dest_path
if [ $? == 0 ]; then
	echo -e "\e[1;32mPull complete. Beginning push...\e[m"
else
	echo -e "\033[1;31mFailed to fetch updates. Please diagnose and rerun the script.\033[m"
	exit;
fi
rsync -avucr $excludes -e "$sshcommand" $source_path $username@$server:$dest_path
if [ $? == 0 ]; then
	echo -e "\e[1;32mPush complete. Script is successful.\e[m"
else
	echo -e "\e[1;31mPush failed. Please diagnose and rerun the script.\e[m"
	exit;
fi

It is written in Bash, and relies on RSync being installed on both systems. If this counts, then including the readme and excludes example file, the entire project comes in at under 100 lines.

I do wish that there was BASH syntax highlighting support, but Perl isn't so far off so if something looks out of place in the highlighting, that's why.

Now you just need to tie it down with some inotify goodness, right?  Or just "cheat" and use incron to trigger it when folder contents change.

If I understood the theory correctly, I made a basic Huffman codec in Python

def bucketize_string(input):
    buckets = {}
    for idx in xrange(0, len(input), 1):
        char = input[idx]
        if char not in buckets:
            buckets[char] = 1
        else:
            buckets[char] += 1
    return buckets

def create_nodes(leaves, freq_idx = 1):
    nodes = []
    if len(leaves) > 1:
        for idx in xrange(0, len(leaves)-1, 2):
            if type(leaves[idx+1]) is tuple:
                nodes.append([leaves[idx], leaves[idx+1], leaves[idx][freq_idx] + leaves[idx+1][1]])
            else:
                nodes.append([leaves[idx], leaves[idx+1], leaves[idx][freq_idx] + leaves[idx+1][freq_idx]])
        if idx < len(leaves) - 2:
            nodes.append(leaves[idx+2])
    else:
        nodes.append(leaves[0])
    return nodes

def build_sym_table(tree):
    sym_table = {}
    map_node(tree, sym_table, '')
    return sym_table

def map_node(node, sym_table, code):
    for x in xrange(0, len(node), 1):
        if type(node[x]) is list:
            map_node(node[x], sym_table, code + str(x))
        elif type(node[x]) is tuple:
            sym_table[node[x][0]] = code + str(x)

def huffman_encode(in_string):
    import operator
    buckets = bucketize_string(foobar)
    tree = create_nodes(sorted(buckets.items(), key=operator.itemgetter(1)))

    while len(tree) > 2:
        tree = create_nodes(tree, 2)
    sym_table = build_sym_table(tree)

    code = ''
    for x in xrange(0, len(in_string), 1):
        code += sym_table[in_string[x]]
    return code, tree
    
def huffman_decode(in_stream, tree):
    message = ''
    node = tree

        node = node[symbol]
        if type(node) is tuple:
            message += node[0]
            node = tree

    return message

This has no practical purpose (for one it expands rather than compresses), but I was bored.

 

EDIT again: I think I finally got it down. It now theoretically compresses :3

a little text based ellipse solver that asks for defining variables and then outputs useful information such as the vertexes, endpoints, foci, and what kind of ellipse has been defined (horizontal, vertical, or a circle)

inspired by my college math class unit on conics and ellipses.

This is a .bat script that temporally sets the APPDATA folder to a different folder to allow minecraft to be run off a flash drive.  It also has a built in version switcher. I used this to play minecraft at school. More to showoff than to actually play. Its value is probably less since minecraft does those things now. However this works with hacked clients that allow you to play offline multiplayer with any username. These hacked clients only work up to release 1.5.2 but it can be fun to go back in time sometimes. It also has an ASCII grass block. I thought it was a nice touch.

Now, you talking about raw code? Or just the user-edited portion of a VS project?

[h3adsh0tzz]

i call this program "SHAForce1".

 

Not quite 100 lines, little bit over but i already had made this a while back and thought it could be kinda cool. 

 

You supply 2 files, a file full of SHA1 hashes and a dictionary, All the hashes will then be testing and if there are any matches then they will be displayed.

 

total: 144 lines (had around 160 on the full project with annotations)

So I needed to come up with a way to clean up some whitespaces in CSV's that I was reading in.  I needed to both trim the ends of the strings, as well as convert multiple whitespaces into a single white space.  Took a stab at doing it with Regular Expressions and came up with

 

^\s*+([^\s])|(\s)\s*+|([^\s])\s*+$

And you would replace it with

\1\2\3

 

So it would take something like this:

Quote

<     Smith,    John                 H                  >

The <> brackets just signify where the string begins and end

 

And it would convert it into

Quote

<Smith, John H>

Yes, that many extra white spaces is unrealistic, but all it takes is one extra space to throw off my parser.

 

Sadly, as beautiful as it is, it does have some slight performance problems, and I ended up instead just first trimming the string, then using the regex:

\s+

And Replaced it with a single space.

This was something I didn't think I needed it until I started building computers for my friends. I wanted something easy for me to create junctions on fresh windows installations that had a boot drive (usually an ssd) and a storage drive (usually an hdd). I wanted to do it only for the Documents, Music, Pictures, Videos, and Downloads folders. So I created a batch file to have the user input the drive letter and the program creates the directories in the secondary hard drive and copies all the files from the boot drive to the storage drive. Then it deletes the folders from %UserProfile% and makes a junction to link the storage drive folders to the %UserProfile%.
