  • Remove excess noise from a set of mp4 videos.

    Full command: for f in input/*; do BN=$(basename "$f"); ffmpeg -i "$f" -vn "temp/$BN.flac"; sox "temp/$BN.flac" "temp/$BN-cleaned.flac" noisered profile 0.3; ffmpeg -i "$f" -vcodec copy -an "temp/$BN-na.mp4"; ffmpeg -i "temp/$BN-na.mp4" -i "temp/$BN-cleaned.flac" "output/$BN"; done This was over the 255 character limit and I didn't feel like deliberately obfuscating it. 1. Create 'input', 'output' and 'temp' directories. 2. Place the files that you want to remove the hiss/static/general noise from in the input directory. 3. Generate a noise reduction profile with sox using 'sox an_input_file.mp4 -n trim x y noiseprof profile', where x and y indicates a range in seconds that only the sound you want to eliminate is present in. 4. Run the command.

  • Build a Stage 4 cross compiler for x86_64-elf with Gentoo's crossdev

    You may have to disable fortran and openmp using the USE variable too. YMMV.

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Create named LUKS encrypted volume
You need to be root to do this. So check the command before running it. You enter the same password for Enter LUKS passphrase: Verify passphrase: Enter passphrase for /dev/loopn: ___ You can then copy the .img file to somewhere else. Loop it it with losetup -f IMAGENAME.img and then mount it with a file manager (eg nemo) or run mount /dev/loopn /media/mountfolder Acts similar to a mounted flash drive

Destroy all disks on system simultaneously
This command will use the fdisk utility to find all block devices on your system, and overwrite them with data from the /dev/urandom non-blocking random number generator. CAUTION: This will irrevocably erase EVERY SINGLE physical block storage device visible to the fdisk utility, including plugged USB devices, RAID sets, LVM, etc.
