Rachel ☛ Let the network tell you where you are: a nerd snipe story
Wouldn't it be cool if you could just grab a box, plug it in a given spot, and it would somehow start displaying the right set of media? That's what I was thinking when I came up with this idea.

Austin Kleon ☛ How do you draw time?
Sometimes a timeline isn’t completely up to the task of explaining: So much was happening in these years so quickly that it’s hard to get real perspective on it visually — that’s what prose is for. It’s also worth pointing out that a timeline without words or captions doesn’t tell you much.

University of Toronto ☛ Brief notes on making Prometheus's SNMP exporter use additional SNMP MIB(s)
Suppose, not entirely hypothetically, that you have a DSL modem that exposes information about the state of your DSL link through SNMP, and you would like to get that information into Prometheus so that you could track it over time (for reasons). You could scrape this information by 'hand' using scripts, but Prometheus has an officially supported SNMP exporter. Unfortunately, in practice the Prometheus SNMP exporter pretty much has a sign on the front door that says "no user serviceable parts, developer access only"; how you do things with it if its stock configuration doesn't meet your needs is what I would call rather underdocumented.

University of Toronto ☛ Resetting the backoff restart delay for a systemd service
Suppose, not hypothetically, that your Linux machine is your DSL PPPoE gateway, and you run the PPPoE software through a simple script to invoke pppd that's run as a systemd .service unit. Pppd itself will exit if the link fails for some reason, but generally you want to automatically try to establish it again. One way to do this (the simple way) is to set the systemd unit to 'Restart=always', with a restart delay.

How to explore Linux without fully installing it
Linux is a popular free and open-source alternative to the traditional Windows and macOS operating systems. It’s best known for its customization, security, stability, privacy, large supportive community, and great environment for learning about operating systems and computer science concepts.
Yet installing Linux is not the easiest task anyone can complete. While it doesn't take advanced level knowledge to make the switch to Linux, it does take some precautions and preparation to successfully and fully replace your current operating system with Linux.
