How to Replace a System Program without Modifying System Files or Permissions
See this post. This can be used to replace notepad with other program, for example.
Basically,
Under the registry key
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
create a subkey with the name of the exe you want replaced.
Add a string value called Debugger.
Modify Debugger with the command you want run.
When any user tries to run any executable with the name of the subkey, Windows executes the Debugger command with path\name of the original exe and all command line parameters appended. (Did that make sense?)
Solution: Vuze (azureus) seeds getting ‘queued’ status
Wonder why your seed get queued even if you want them to be seeded?
The problem is vuze’s quite poor default values. To understand the problem let me explain a bit more how vuze determines whether to queue an item.
Vuze determines the queue status on few things (in this order):
- First Priority rules (Options/Queue/Seeding/First Priority). Items matching the first priority rules go to the top of the queue. Please note that first priority have ignore rules which override the “matching rules”
- Ignore rules (Options/Queue/Seeding/Ignore rules). Items matching the ignore rules go to the bottom of the seeding queue and probably they will never seed.
Most forum posts mention “correct” rules for ignore rules but fail to mention that First priority rules have their own ignore rules too.
I have attached my working settings but feel free to tune them for your connection and needs.
Powershell script, executing commands to lots of files
Following powershell script goes recursively the folder “J:\pictures” and converts all avi file to mp4 files. It uses ffmpeg (remember to download newest binary)
I couldn’t get invoke-expression to work (it gave some error about “-” operator), so I just sticked all the commands to a text file d:\commands.txt and run it as a normal batch script.
I used this script to convert lots of videos shot with my camera to more compatible format.
"" > d:\commands.txt
foreach ($file in get-childitem "j:\pictures" -recurse -include "*.avi"){
$ffmpegprog = "`"C:\Program Files (x86)\WinFF\ffmpeg.exe`"";
$ffmpegparams = " -threads 2 -f mp4 -vcodec libx264 -b 1500k -flags +loop -cmp +chroma -deblockalpha 0 -deblockbeta 0 -b 1500k -maxrate 2000k -bufsize 4M -bt 256k -refs 1 -bf 3 -coder 1 -me_method umh -me_range 16 -subq 7 -partitions +parti4x4+parti8x8+partp8x8+partb8x8 -g 250 -keyint_min 25 -level 30 -qmin 10 -qmax 51 -qcomp 0.6 -trellis 2 -sc_threshold 40 -i_qfactor 0.71 -acodec aac -ab 256k -ac 2 -ar 44100";
$command = ($ffmpegprog + " -i `"" + $file.FullName + "`"" + $ffmpegparams + " `"" + [System.IO.Path]::ChangeExtension($file.FullName, ".mp4") + "`"");
$("$command") >> D:\commands.txt
}
You can just copy-paste the file to a powershell window.
For some reason direct execution of the commands.txt batch file didn’t work so you can just run it throught type
type d:\commands.txt > d:\commands.bat

Ubuntu: Trash can support on NTFS volumes
As Wyatt Smith said on https://answers.launchpad.net/ubuntu/+question/52985 :
To enable a trash can on a NTFS partition you will have to make an entry in your /etc/fstab file. You must specify the drive by UUID and assign a userid.
To discovery the UUID of the external drive. Please plug the drive in and then type
sudo blkidTo edit your fstab file with root permission
gksu gedit /etc/fstabHere is an example of how the entry should look. Please replace the UUID and mountpoint with the appropriate values from your system
# NTFS Partitions
UUID=19031A6158945892 /media/DATA ntfs-3g defaults,uid=1000,locale=en_US.UTF-8 0 0Save and exit.
To remount (unmount then mount) all drives listed in /etc/fstab
sudo umount -a
sudo mount -aYou should then see a hidden trash folder on your ntfs drive.
After this deletes are not permanent and they should be visible in the trash.
Annoying nonbreakable space character by accident
Have you noticed that when you press alt gr + space in terminal window, a non-breakable space character is outputted? It looks just like normal space but it prevents commands from working.
From example ‘[alt gr + space] ls’ cannot be interpreted but ‘[space] ls’.
Solution is to change keyboard behaviour:
From here
This feature can be configured in:
System
->Preferences
->Keyboard
->Layouts
->Layout options…
->Using space key to input non-breakable…
Change the setting to ‘usual space at any level’ setting.
Please note that this problem may not occur in some keyboard layouts.
