Raymond P. Burkholder - Things I Do

Learn something, a parameter for dmesg to look for certain types of messages:

root@host02:~# dmesg --level err
[    0.239659] ACPI: SPCR: Unexpected SPCR Access Width.  Defaulting to byte size
[    2.676888] mpt2sas_cm0: overriding NVDATA EEDPTagMode setting

Man page has various level categories:

• subsys - The message sub-system prefix (e.g., "ACPI:").
• time - The message timestamp.
• timebreak - The message timestamp in short ctime format in --reltime or --human output.
• alert - The text of the message with the alert log priority.
• crit - The text of the message with the critical log priority.
• err - The text of the message with the error log priority.
• warn - The text of the message with the warning log priority.
• segfault - The text of the message that inform about segmentation fault.

Hacker News had an entry today on Text Only News WebSites - a fast way to get to the meat of the matter.

I wish it was RSS like, but there are alternatives for summaries (independent of anything yahoo/google/facebook might produce):

• The Brutalist Report - snapshot of of what is happening across various news sources
• skimfeed - snapshot of what is happening across various news sources
• github: awesome console services - meta link to find more console stuff
• Another take on from the seeing impaired, something we can learn: "I’ve been getting a lot mileage out of safari’s and brave’s reader mode"
• markets.sh - meh, summaries might be ok, but can't copy text for stuff I want to keep
• teddit worldnews - kinda like a reddit thingy, but not sure how it works

Now if I could find something that scrolled as stuff changes, .... oh wait, the closest would be irc.libera.chat with ##hntop (hackernews), ##news (world news), ##alerts (earthquakes, electrical, ...)

Obtaining interface list, which can be used to drill down into details:

On Debian Linux, fonts can be downloaded and installed in the user's directory, and do not need to be installed into the protected system directories.

Ensure the local directory is available:

mkdir -p ~/.local/share/fonts

Font files can be unzipped and the .ttf files can be copied over into that directory

Refresh the font cache

fc-cache -f -v

Review the fonts:

fc-list

A number of fonts can be installed with:

apt install ttf-mscorefonts-installer fonts-aenigma

1001 Fonts has a wide range of fonts compatible with Linux.

As a side note, pixabay has a good variety of clipart selections.
