How To Install Memtester on Ubuntu 20.04 | 22.04 LTS
In this guide, we will show you how to install Memtester on Ubuntu systems.
Memtester is an effective userspace tester for stress-testing the memory subsystem. It is very effective at finding intermittent and non-deterministic faults. Note that problems in other hardware areas (overheating CPU, out-of-specification power supply, etc.) can cause intermittent memory faults, so it is still up to you to determine where the fault lies through normal hardware diagnostic procedures; memtester just helps you determine whether a problem exists.
Memtests are memory-testing programs that check for faults in the RAM of your system. Memtest or Memtest86+ reads data, writes the memory address patterns, and checks the errors. It can output a list of bad RAM regions usable by the BadRAM kernel patch so that you can still use your old RAM with one or two bad bits.

Color Formats in CSS
CSS has a whole slew of different color formats: hex codes, rgb(), hsl(), lch(), the list goes on!
Which one should we use? It might seem like an inconsequential decision, but there are some pretty important differences between them. And, honestly, I think most of us are prioritizing the wrong things. 😅
In this tutorial, I'll take you on a tour of the different options. We'll see how they work, how we can decipher them, and how we can use them to our advantage. Later, I'll show you how modern CSS lets us make on-the-fly adjustments, if we pick the right color format.

Generic number compression (zstd)
I have done a lot of work that involves compressing and uncompressing data. Most often, I work on data that has specific characteristics, e.g., sorted integers. In such cases, one can do much better than generic compression routines (e.g., zstd, gzip) both in compression ratios and performance.
