Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

May need to use pavucontrol to set sound to correct things, use when ffmpeg is running.

This command won't delete resource forks from an HFS file system, only from file systems that don't natively support resource forks.

Assumes that the files are named in numerical order (ie. 01 Filename.mp3). It will set the track number as tracknumber/totaltracks (ie. 1/14). This will write both ID3v1 and ID3v2 tags.

Note: This only writes the track numbers.

Save as a bash script and run as root to set the ondemand cpu frequency governor for all cpu cores. Name the file ondemand. Change 'ondemand' in the argument to performance or your preferred governor to do the same thing but set all cpu cores to use the performance governor (or your preferred governor)

This command sets the volume for the main PulseAudio "sink" (usually the ALSA output interface) to the maximum, 100% (the 0x10000 in the command). To set it to an arbitrary volume, replace 10000 with the volume you want times 100 (so 75% becomes 7500).

This encodes it in ogg format.

Does on-the-fly encoding of the incoming stream.

Great for radio streams as they're often flv format.

These part of the command:

svn status | grep '^\?' => find new file or directory on working copy

sed -e 's/^\?//g' => remove "^" character on the first character of file name

xargs svn add => add file to subversion repository

You can modify above command to other circumtances, like revert addition files or commit files that have been modified. ^_^

Alternately for those without getent or only want to work on local users it's even easier:

cut -d: -f1 /etc/passwd|xargs -n1 passwd -e

Note that not all implementations of passwd support -e. On RH it would be passwd -x0 (?) and on Solaris it would be passwd -f.

In some case, you need to use remote gui on servers or simple machines and it's boring to see "cannot open display on ..." if you forgot to export your display. Juste add this line in .bashrc on remote machine. Dont forget to allow remote client on your local X server :

It will change the reserve_lock attribute to all AIX EMC disk attached.
