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).
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.
Recently, I have been able to purchase an SSD from Micron, the 5200 ECO with a 3840GB capacity. The purchased item is branded by HPE (Hewlett Packard Enterprise, model VK003840GWSXL). In order to update the device's firmware, I encountered problems, the solution of which I would like to share. You are welcome.
Xiaomi Wireless power bank (model PLM11ZM) – with 10,000mAh battery capacity is the first Xiaomi device used as a backup power bank with wireless charging function. I recently purchased this product and would like to share my first thoughts.
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).
