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).

UNMS / UISP on EL8 Linux
I published a script that executes the installation of UNMS (Ubiquiti Network Management System) on CentOS 8 Linux / RHEL 8, despite the lack of support for those distribution by the manufacturer.
Installation manual and download link can be found in projects – "UNMS / UISP for CentOS 8 Linux installation script".
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.
iVCam – smartphone instead of webcam
Chinese software development company – e2esoft is publisher of iVCam application. Software website link: https://www.e2esoft.com/ivcam/
It is made of smartphone app (Android or iOS) and for computer (Windows 7/8/10). It is allow you to use smartphone connected to WiFi network (the same that computer is connected) as webcam device.
Some time ago i sent Polish translation, but instead they put own translation (that isn't bad). If you would like to use the one i prepared, you may download this file: strings.xml.
To make it work just put it inside "resource" directory, where software is installed (default C:\Program Files\e2eSoft\iVCam\resource) overwriting file that is already there with the same filename.
This file is prepared for version 5.3.5 of iVCam.

Since I often solve computer problems using my own hardware, I decided to buy the cheapest and smallest size USB devices to connect computers to LAN and WiFi networks. In this entry I will present what I bought and how it works (iperf3).
