RPM cheat sheet
November 20, 2009
The worst thing about commercial Linux is RPM. I can never remember the command line incantations required for even fairly simple tasks.
While yum eventually takes away the pain of applying software updates–so long as you’re not in a hurry–there are all kinds of other tasks it doesn’t handle. I therefore rely on an RPM [...]

Documentation as an indicator of code quality
September 25, 2009
I often have to shunt around Lotus Domino databases, as well as all kinds of log files and bundles of XML data. I’ve got a cable modem connection to my home office, but still, uploads can take a while. So data compression is still important to me, and the newer LZMA algorithm can make a [...]

OpenSSH flaw: workaround
May 21, 2009
A flaw in the SSH protocol is starting to get more widespread attention.
It appears that a workaround is available: disabling CBC ciphers in favor of CTR. To do so, edit /etc/ssh/sshd_config and add the following:
Ciphers arcfour128,arcfour256,arcfour,aes128-ctr,aes192-ctr,aes256-ctr
That’s the default list of SSH ciphers, minus the CBC ones.

Git
February 20, 2009
Linus Torvalds’ version control hack, git, has become flavor of the month in the open source world. Not everyone is happy.

Server maintenance at home
January 25, 2009
I’ve been upgrading my home media server to Ubuntu 8.10. I’ve taken the opportunity to reformat in ext3.
So, farewell then ReiserFS. You gave me solid service for years, but what with vendor lock-in and lack of ongoing development, it’s time to move on. I’ve had issues with JFS support in Ubuntu, and XFS has some [...]
