ffmpeg screen recording X11
Tuesday, December 3, 2013, 09:15 AMSo, after much looking around, testing, compiling and upgrading,
I finally found an excellent solution that seems to work better than
any other: ffmpeg. The latest version (2.1) has support for x11grab,
and hence can record directly from the X11 screen. Needless to say,
it produces excellent quality video without frameloss or compression,
and supports virtually any format I could ever need. The best part is
that audio is properly recorded alongside with the video and multiplexed
with the video on the fly for perfect synchronization for my voice-over
needs. Oh, and ffmpeg is multithreaded in case a single core is not
fast enough. Here is an example commandline that works just fine:
ffmpeg -video_size 800x600 -framerate 25 -f x11grab -i :0.0 -f alsa -ac 2 -i hw:0,0 output.mkv
The KDE 4 plasma desktop supports a mouse cursor for magnification in
the vicinity of the mouse cursor, this way I can scale the video down
and the important part is still perfectly readable.
All set now to make my instructional videos :-)

SCUBA at South Baker
Wednesday, October 23, 2013, 08:28 AMI came across this picture of me when I worked summers on a dive boat with Jim Moss & Jim Mills. We were about 50 miles out in the Gulf of Mexico diving down to about 120 feet on the oil rigs at South Baker.

Break in Service
Wednesday, October 2, 2013, 08:12 AM
We dropped offline yesterday afternoon about 3:15. After checking our routers & switches and touching base with staff at ESC2 I placed a trouble ticket with CenturyLink #14604157. They said they'd have a technician here by 12 midnight. Circuit came back up around 4 and was fully stable shortly after 8 PM.

Monday, September 30, 2013, 08:01 AMChanging and reusing passwords
Over time, passwords may be compromised in many ways, including:
Users may share them with friends or coworkers.
Users may write them down and they may subsequently be exposed.
Passwords may be guessed, either by humans or software.
The servers that store passwords may be compromised and their passwords acquired by an intruder (encrypted, hashed or plaintext).
The networks over which passwords travel, between a user's workstation and the system into which the user signs in may be compromised, again leading to compromise of a password.
Users may be tricked into revealing their passwords (phishing).
The help desk may be tricked into giving an intruder a valid password (social engineering).
To limit the usefulness of passwords that have been compromised, a best practice is to change them regularly. A common rule in many organizations is to force users to change their passwords when they log in, every 60 or 90 days.
In general, users should be required to change their passwords regularly. The password expiry interval should not be longer than 90 days. Hitachi ID Systems Best Practices
For the same reasons, users should not reuse old passwords, as they may already have been compromised. Many systems support this by recording some representation of old passwords and ensuring that users cannot change their password back to a previously used value. Hitachi ID Systems Best Practices
When password history is enforced, users may figure out the number of passwords stored for this purpose. As this number is usually 10 or fewer, a user who would prefer to keep his password the same may make a series of consecutive password changes where the final password value is the same as the first one.
To defeat such "smart" users, some systems also enforce a password rule that limits the number of password changes that a user can make in any given day. By making the process of defeating password history take several days, users are discouraged from trying to reuse old passwords.
A better approach, though not available on all systems, is to simply maintain an unlimited number of entries in each user's password history. Since disk storage is inexpensive, this approach is practical on modern systems. With this approach, users can change their passwords as often as they like -- and still never be able to reuse old ones.
