* Made, verified and distributed backups and took a snapshot of the system disk. [[User:Jukeboksi|Jukeboksi]] ([[User talk:Jukeboksi|talk]]) 19:44, 26 December 2018 (UTC) | |||

* Snapshotting complete with a downtime of 4 minutes. [[User:Jukeboksi|Jukeboksi]] ([[User talk:Jukeboksi|talk]]) 16:35, 16 November 2018 (UTC) | |||
* Machine rebooted to new kernel. Going to take a snapshot of the system disk. This is going to cause a freeze, usually only for 3-4 minutes, but today the snapshotting of the other machine caused a freeze of 24 minutes, so the site may be unavailable for a while.

* Rebooting the machine to take kernel version 4.9.0-8-amd64 into use. [[User:Jukeboksi|Jukeboksi]] ([[User talk:Jukeboksi|talk]]) 15:39, 16 November 2018 (UTC) | |||
* Made, verified and distributed backups. Updated software with apt. There is a new kernel version. Going to reboot an almost identical server with less important sites on it first to see that all goes ok with the new kernel version. After that going to reboot this server for the new kernel version. Expected downtime will be 1-2 minutes.

* Moved the little info on countries that [[Consumerium list of lists]] had to [[Countries of the world]] and am aiming to use that as a central place to add pieces of info on countries. [[User:Jukeboksi|Jukeboksi]] ([[User talk:Jukeboksi|talk]]) 14:34, 27 October 2018 (UTC) | |||

* Today I did a small test to find out how much CPU load affects the power consumption of a laptop. I did this because I have recently resumed contributing my computational resources to the [[w:Berkeley Open Infrastructure for Network Computing]] or BOINC for short and am considering whether to add running BOINC to the things suggested to consumers who stumble upon the development wiki [[Main Page]]. | |||
:When, a Lenovo ThinkPad X230, was being '''mostly idle''' at 20-30% CPU utilization it consumed on average '''30W''' or slightly under and when I put all cores into full labour with the [[w:hardware stress test]] program for Linux aptly named just 'stress' with the parameter '--cpu 4' (the CPU has 4 cores), which causes CPU utilization going to 100%. '''Under full workload''' on the CPU cores the computer used an average of '''40W''' so '''cranking all CPU cores to the max''' causes an approximate '''+35% electricity consumption'''. | |||
:Also tested an another computer, a Dell Inpiron E6220 that had a very low power consumption of around '''17W''' when idle with 10% of CPU in use and the stressing of the CPU to the max caused a much bigger rise in its electricity consumption: It went to '''52W''' so that is a rise of '''+206% electricity consumption''' or '''+35W''' in terms of absolute consumption. | |||
:It is hard to draw a conclusion from a sample of only 2 computers, but it is clear that CPU utilization does play a major role in how much power the computer consumes. [[User:Jukeboksi|Jukeboksi]] ([[User talk:Jukeboksi|talk]]) 13:41, 23 October 2018 (UTC) | |||
