Extracting the icons from an EXE in PHP on Linux

Posted by mrkmg on January 21, 2013 No comments

For a project I am working on I wanted to add the ability to see an EXE’s built in icon file in a web application. I am running a Debian Linux / PHP5 stack and figured out a way to extract a png out of a Windows EXE. To accomplish this I am using icoutils to extract an ico file from the exe, then search for the target size icon I want and extract a png from that ico file. The script is commented and should be pretty easy to understand and edit to fit your needs. Help with icoutils can be found on the wrestool and icotool man pages. The gist is below:

<?php // Code snippet to extract the icon from an exe file on a Linux system -- tested on Debian Wheezy // Install icoutils on your system e.g. sudo apt-get install icoutils // Web process must have write privileges to /tmp ///** Config **/// $input_file = '/path/to/program.exe'; $dest_file = '/path/to/image.png'; $dest_size = 64; // Will get the best quality icon at or below this size. ///** End Config **/// $temp_dir_base = '/tmp/iconextract/'; $tmp_offset = 0; while(file_exists($temp_dir_base.$tmp_offset.'/')){ //Ensure working directory is empty $tmp_offset += 1; } $tmp_dir = $temp_dir_base.$tmp_offset.'/'; mkdir($tmp_dir,0777,true); //Create a temporary folder to work in exec('wrestool -x '.str_replace(' ','\\',$input_file).' -o '.$tmp_dir); //Extract ico files $icon_files = glob($tmp_dir.'*.ico'); //Find all ico files $max = 0; $file = 0; $index = 0; foreach($icon_files as $file_offset=>$ico){ //loop each match exec('icotool -l '.$ico.' --icon',$list); //get each icon inside the file foreach($list as $i){ //Loop through each icon preg_match_all('/--index=(?P<index>\d+) --width=(?P<width>\d+) --height=(?P<height>\d+)/',$i,$a); if($a['width'][0] > $max and $a['width'][0] <= $dest_size){ $max = $a['width'][0]; $index = $a['index'][0]; $file = $file_offset; } } } if($max > 0){ //If we found one, extract it to the destination exec('icotool -x '.$icon_files[$file].' -i '.$index.' -o '.str_replace(' ','\\',$dest_file)); } else{ exec('rm '.$tmp_dir.' -r'); //Clean out tmp files $error = "Could not find a sutiable icon file"; throw new Exception($error); } exec('rm /tmp/iconextract -r'); //Clean out tmp files ?>

jQuery.flipper: A jQuery plugin for retro clock-like animations, and more!

Posted by mrkmg on October 10, 2012 No comments

After a little bit of searching around on the web for a javascript solution to create a flip-down animation for a clock a wanted to build, I decided to build my own. I started from this flip-down clock animation css3 example/test page. I have a github repo here which documents all the options and usages. I also have two examples, one that demonstrates all the options and one that shows off the queueing feature.

Again, Important links:

Please feel free to clone the repo and make your own transitions, or maybe improve upon my current transitions.

TPM: Ticks Per Minute PHP Class

Posted by mrkmg on September 18, 2012 No comments

I have been writing a couple PHP CLI scripts, some that are long running. I wanted a simple way to keep a running average of how many times certain actions were taking place. In comes TPM. A very small and simple class that keep tracks of “ticks” per minute for you.

<?php class TPM { public $useCtime = true; //If true, use current time for tpm calculation. If false, use last tick. public $purgeOlderThan = 15; //Time in minutes to purge old data private $ticks = array(); //Add a tick public function tick(){ $this->ticks[] = time(); } //Get the Ticks per Min public function getTPM(){ $this->clean(); sort($this->ticks,SORT_NUMERIC); $count = count($this->ticks); if($count < 2) return 0; $lowest = $this->ticks[0]; $highest = $this->useCtime?time():$this->ticks[$count-1]; if($lowest == $highest) return 0; $min = ($highest-$lowest)/60; return round($count/$min,2); } private function clean(){ $before = time()-($this->purgeOlderThan*60); $this->ticks = array_filter($this->ticks,create_function('$a','return $a>'.$before.';')); } } ?>

Hope you find it useful!

Perl Script to automatically put emails into a MySQL Database

Posted by mrkmg on September 13, 2012 No comments

I have written/highly modified a perl script to take piped in emails and insert them into a MySQL database. I accomplish this by having my MTA pipe them to this script. You can download the script from this Github Repo, or you can download it directly from here.

This script requires that you have Perl installed with the following Modules:

DBI
Email::MIME
Email::Address
HTML::Strip

To use this script, first replace the following items in the script:

_DATABASE_ The name of the Schema/Database
_SERVER_ The host of the MySQL Server. ex: localhost, 192.168.0.10, etc
_USER_ The user of the MySQL database
_PASSWORD_ The password of the MySQL user

Place the script on your server and make sure it is accessible and executable by your MTA. Set your MTA to pipe incoming emails to this script. That should be all that is needed.

Original Script: http://www.blazonry.com/perl/mail2mysql.php

Cronic, fixing excessive cron emails

Posted by mrkmg on May 17, 2012 No comments

Earlier today I found a very very useful program to help cut down in the massive amount of spam system administrators receive from cron emails. I decided to create a simple installer for it. Check out cronic at http://habilis.net/cronic/. To install automatically to your system, just run this command as root.

wget http://mrkmg.com/install_cronic.sh -qO - | sh

There is no error checking in the installer, use at your own risk.

install_cronic.sh for your reference if you do not want to trust running a shell script from the internet.

#!/bin/sh
mkdir /tmp/cronic
echo "Downloading Cronic from habilis.net"
wget http://habilis.net/cronic/cronic -qO - > /tmp/cronic/cronic
echo "Installing Cronic into /var/local/cronic/cronic"
mkdir -p /var/local/cronic/
cp /tmp/cronic/cronic /var/local/cronic/cronic
chmod 755 /var/local/cronic/cronic
echo "Linking Cronic into /usr/bin"
ln -s /var/local/cronic/cronic /usr/bin/cronic
echo "Cronic is installed and ready to be used. Checkout"
echo "http://habilis.net/cronic/ for more information."
echo "Installer created by Kevin Gravier <[email protected]>"

Simple Floating Clock for Linux CLI (tclock)

Posted by mrkmg on May 16, 2012 No comments

I found a very nice and easy to use script to place a floating clock on your CLI in linux.

wget https://gist.github.com/raw/2713194/cb9eb0426dc81f3411c7bb2e592963378bb3b2d7/tclock.sh
chmod 755 tclock.sh
./tclock.sh&

#!/bin/sh ### Floating Clock ###################################################### # Created by Scott Garrett https://github.com/Wintervenom # # Found via https://bbs.archlinux.org/viewtopic.php?pid=557778#p557778 # # Maintained By Kevin Gravier <kevin@mrkmg.com> # ######################################################################### cols=`tput cols` touch /tmp/tclock.run while [ -e /tmp/tclock.run ]; do tput sc tput cup 0 $((cols - 13)) printf " $(date +%r) " tput rc sleep 1 done

I also made a simple installer

wget http://mrkmg.com/install_tclock.sh -qO - | sh

Axel Download Accelerator for Windows – with Graphical Frontend

Posted by mrkmg on February 14, 2012 No comments

So a while back I showed you how to speed up your downloads for free on OSX with Axel and a simple applescript. Well it looks like someone has compiled Axel on Windows (http://st0rage.org/~n2j3/?page_id=225717166) . I went ahead and created a very simple frontend for it. Feel free to download and try it out.

**EDIT 2/15/2012** I updated the frontend to look a little better, added a title and got rid of the the program icon. Also defaults are now set and if you have a valid URL in your clipboard it will automatically paste it into the URL field. I also created a simple installer. Nothing extra in there either, no ads, no bloatware, no spyware, etc.

PHP function to generate a color from a text string

Posted by mrkmg on January 13, 2012 No comments

So I was in need of a way to generate a unique color based on a string input. I wanted to be able to define a minimum brightness and how unique each color should be. After a little googleing, I did not find anything I liked, so I wrote my own real quick. Hopefully someone else can find a use for this function as well

<?php /* * Outputs a color (#000000) based Text input * * @param $text String of text * @param $min_brightness Integer between 0 and 100 * @param $spec Integer between 2-10, determines how unique each color will be */ function genColorCodeFromText($text,$min_brightness=100,$spec=10) { // Check inputs if(!is_int($min_brightness)) throw new Exception("$min_brightness is not an integer"); if(!is_int($spec)) throw new Exception("$spec is not an integer"); if($spec < 2 or $spec > 10) throw new Exception("$spec is out of range"); if($min_brightness < 0 or $min_brightness > 255) throw new Exception("$min_brightness is out of range"); $hash = md5($text); //Gen hash of text $colors = array(); for($i=0;$i<3;$i++) $colors[$i] = max(array(round(((hexdec(substr($hash,$spec*$i,$spec)))/hexdec(str_pad('',$spec,'F')))*255),$min_brightness)); //convert hash into 3 decimal values between 0 and 255 if($min_brightness > 0) //only check brightness requirements if min_brightness is about 100 while( array_sum($colors)/3 < $min_brightness ) //loop until brightness is above or equal to min_brightness for($i=0;$i<3;$i++) $colors[$i] += 10; //increase each color by 10 $output = ''; for($i=0;$i<3;$i++) $output .= str_pad(dechex($colors[$i]),2,0,STR_PAD_LEFT); //convert each color to hex and append to output return '#'.$output; } ?>
