Correction of a small but annoying error
Byetzion 19/04/200719/12/2023

For some reason (probably a typo) I’ve missed an important character in an example I gave here, but I have just recently fixed it. Anyhow, to clarify this, here is the extended description of the correction. The $IFS Bash system variable defines what is the default separator between strings. Changing it can help when dealing…

RHEL4 tends to change network interfaces names
Byetzion 06/07/2007

RHEL4 tends to change the names of network cards when there are more than one. If you had a NIC called eth0 during install time, it doesn’t mean that it will maintain that name after the first reboot. It could switch names with its friend, and be called now eth1, while the previous eth1 name…

Its main disadvantages are in the need to constantly monitor it, and make sure it does what’s expected. Also – in some cases – performance might be affected greatly….

Byetzion 02/03/202227/01/2023

Diving videos tend to be blueish. There are tools to automatically fix it, or at least – enhance the video so that the colours appear more natural. Unfortunately, most of these tools either don’t work well with Linux, or with my phone. After a short investigation, I was able to produce a satisfactory result with…
