Comparison of rar, bzip2, lbzip2 compression

Recently, I've been busy preparing various directories for additional archiving in Linux (it's about files from the /var/log/ location) containing archives of reports of performed operations in the system and running programs (services such as www etc.). Since I often use archiving to RAR format, I decided to see if it would work in this case as well.

New script – Nextcloud installer for Linux Debian 11

I wrote a script that installs Nextcloud package (an alternative to other disk services in the so-called cloud), in Debian 11 (Linux). To work it requires only a clean system, everything will install and configure itself (so that it works on the local network, the operation outside must be configured by the user).

Today I had the opportunity to update the firmware of the Mellanox ConnectX-3 card, and I thought I'd give a closer look at the process (it should work for previous ConnectX series card models as well).

Corel error on startup – solution

Some time ago I came up with an idea to move some folders on a Windows computer to another (bigger) drive. From that moment Corel (CorelDraw or Corel PHOTO-PAINT) welcomed me with a message:

Please reconnect the device that has the file is location, or choose a new folder. In the meantime, content will be saved in the Corel default location. You can move the content after the file location is restored.

Short review of Marshall Kilburn II

Some time ago I bought a small portable speaker (i.e. one with a battery), which is used to play sound from my laptop or phone, and occasionally a TV set. I was looking for good middle and low frequencies. Before the purchase, I compared in one of the stores several devices of this type: Marshall Kilburn II, JBL Charger 4 and Xtreme 2, Sony XB43 and XB41. The test consisted in playing music from two phones connected via Bluetooth to two different devices at once. The same song was played, more or less in half, and subjectively Marshall did the best job for me. An additional advantage is the fact that it does not shine on the front, and the construction seems to be very good quality.
