VSHN.timer #123: How Does Stuff Work?

10. Jan 2022

Welcome to another VSHN.timer! Every Monday, 5 links related to Kubernetes, OpenShift, CI / CD, and DevOps; all stuff coming out of our own chat system, making us think, laugh, or simply work better.

This week we’re going to learn lots of new things, and how to remember them.

1. Network Time Protocol (NTP) is probably the oldest distributed application in the Internet (from 1979!), but how do computers coordinate their clocks with it? Well, now you know.


2. WHOIS dates back to 1982 and is another relic from the beginnings of the Internet, back when it was known as the ARPANET. How can you use it, and why? Well, now you know.


3. The JPEG format (and the Web) exploded in popularity after Mosaic introduced the <IMG> tag in 1993. High-resolution photos over a 28 kbps modem? Of course! But how do they work? Well, now you know.


4. Git messages are one of the cornerstones of software team communication, but how to write better ones? Well, now you know.


5. Your brain has only limited capacity, but you have subscribed to VSHN.timer. How to remember all the things you have learnt this week? Well, build a second brain and presto!


Do you know how other things work? Do you have a second brain? Would you like to share your knowledge about how stuff works with the community? Get in touch with us, and see you next week for another edition of VSHN.timer.
