Looking into Linux user logins with lslogins

15.January
One convenient way to list details about user logins on a Linux system is to use the lslogins command. You'll get a very useful and nicely formatted display that includes quite a few important details. On my system and likely most others, user accounts will start with UID 1000. To list just these accounts rather than include all of the service accounts like daemon, mail and syslog, add the -u option as shown in the example below. $ sudo lslogins -u UID USER PROC PWD-LOCK PWD-DENY LAST-LOGIN G...

14.January
Pat Gelsinger’s return to Intel after a 12-year absence has been greeted positively, with the stock jumping 8% on the news Wednesday, analysts lauding it, and apparently even Intel staff approving, indicating he remained popular there despite leaving the firm in 2009.

Here's the bash script: #!/bin/bash echo "How are you doing?" read ans Here's the expect script that provides the response to the query: #!/usr/bin/expect set timeout -1 spawn ./ask # ask is name o...

You’re not imagining things, there is a serious chip shortage

11.January
If you’ve noticed components are hard to get these days, you are not alone. The supply of computing components can get a little tight around the end of the year but this year is especially bad, much of it due to Covid-19-related issues. Intel spent much of 2020 struggling with CPU shortages. In the latter half of the year it was hit with chipset shortages, with the B460 and H410 chipsets reportedly out of stock through the end of last year, and availability of the Z590 chipset is also constra...
