TW My sysadmin toolbox

Filed under
OSS

I'm only an amateur systems administrator, but I'm also terribly lazy, so I do have a few good tools in my toolbox.

I work for Mandriva. However, all these tools except Urpmi are available and usable on any distribution. Even Urpmi could potentially work on any distribution, if you set up a correct package source.

An interactive process viewer: htop

My first tool is htop. Most Linux users, when they first wanted to find out what was eating all their CPU time, were taught about top. Top tells you what processes are running and how many resources they're using ... in just about the most unfriendly way possible.

The nano editor

Despite having used Linux for more than four years, I still have no idea how to use vi or Emacs, because I use GNU nano.

Recovering audio from a lost format with open source

Back in the early 2000s, we made a family decision to upgrade the living room stereo. The equipment in place at the time was based on a collection of gear that I had purchased some 20 years earlier when I first had a steady post-university income. That early collection could best be described as "industrial chic," most notably the Hafler amplifiers I had built from kits and the Polk speakers made from some kind of composite wood product and finished with an ugly faux-rosewood vinyl wrap. They produced decent sound, but the dorm-room-style decor just wasn't working out in the living room. Those of you who remember the early 2000s will recall that most of the world was still consuming music on CD. Our family was no exception, and we ended up with a fine CD player that had an interesting feature—it was able to decode regular CDs as well as high-definition-compatible digital (HDCD) discs. According to Wikipedia, HDCD is a proprietary audio encode-decode process that claims to provide increased dynamic range over that of standard Red Book audio CDs, while retaining backward compatibility with existing compact disc players.

Linus Torvalds: "I Hope AVX512 Dies A Painful Death"

Linux creator Linus Torvalds had some choice words today on Advanced Vector Extensions 512 (AVX-512) found on select Intel processors. In a mailing list discussion stemming from the Phoronix article this week on the compiler instructions Intel is enabling for Alder Lake (and Sapphire Rapids), Linus Torvalds chimed in. The Alder Lake instructions being flipped on in GCC right now make no mention of AVX-512 but only AVX2 and others, likely due to Intel pursuing the subset supported by both the small and large cores in this new hybrid design being pursued.
