classic





Herbie Hancock - Takin' Off



Personnel:

Herbie Hancock - piano
Freddie Hubbard - trumpet
Dexter Gordon - tenor saxophone
Butch Warren - double bass
Billy Higgins - drums





 This was Herbie Hancock's debut album, released in 1962. The first cut, "Watermelon Man", went on to become a jazz standard, but the entire album is a classic.

listing files and directories

Good article about the ls command in Linux: "16 Practical Examples of Linux LS command for Beginners"

It kinda bugs me that the author used capital letters in the title for the command. But I'm over it. The article contains some great tips. The ls command is one of the first commands most users learn about when they're new to Linux, and even after using Linux for many years, I'm still finding it to be a very useful tool.

Here's one I like to use that wasn't mentioned in the article:

$ ls -dl $PWD/*

I like to use it mainly because it outputs the full pathnames of all of the files and directories in the present working directory (except for hidden ones). Here's an example, from one of my Arch installations:


That listing shows only directories. Here's another example, from within another directory, and this one contains only files:


That's convenient sometimes when I want to copy and paste the full pathname of a file/directory. But most of the time, I'm keeping things simple and using one of these four commands:

$ ls
$ ls -a
$ ls -l
$ ls -al

For more info about the ls command, check out man ls.

on books

Here's a link to an article about one of my favorite authors: "In Praise of Samuel R. Delany"

I've read his books Dhalgren and Stars in My Pockets Like Grains of Sand a couple of times now.

And, here's a very good book that I just finished: Eastward to Tartary: Travels in the Balkans, the Middle East, and the Caucasus by Robert D. Kaplan, first published in November, 2000. More info here: https://www.goodreads.com/book/show/33687.Eastward_to_Tartary

A recent shot of Jupiter:


"This new Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet's trademark Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter's turbulent atmosphere than seen in previous years. The colors, and their changes, provide important clues to ongoing processes in Jupiter's atmosphere. The new image was taken in visible light as part of the Outer Planets Atmospheres Legacy program, or OPAL. The program provides yearly Hubble global views of the outer planets to look for changes in their storms, winds and clouds. Hubble's Wide Field Camera 3 observed Jupiter when the planet was 400 million miles from Earth, when Jupiter was near "opposition" or almost directly opposite the Sun in the sky."

Screengrab, a light-weight screenshot app:


Users can choose to edit the screenshot in another app:


The settings options are simple, yet sensible:


I like that the app stays open between screenshots (xfce4-screenshooter needs to do that!).
