Scale is so hard to comprehend but visuals make it easier!

This clip from YouTube channel morn1415, shows the mass of RBS 2043, the supermassive black hole laying at the galactical centeer of the Phoenix Cluster (=20 billion solar mass) [full video: buff.ly/2zMRH2S]



For anyone who has studied algorithims and has pressed the "I believe button" when thinking about recursion. Watch this video. Really good explanation of the mechanics of what's happening behind the scenes. youtube.com/watch?v=i56B0x…

Did you know that existing tools for measuring collision probability in orbit are insufficient? 🛰️💥🛰️ The Astroscale ATREIDES tool in this @SpaceNews_Inc op-ed offers an improved ability to measure catastrophic collision probability. spacenews.com/op-ed-herding-…

Python metaclasses today while playing single dad. Two of my favorite things.


Russia may be reaching what military theorists call its “culminating point” where it can no longer sustain the attack. If that’s true, it’s a great time to think about a Ukrainian counterattack. wsj.com/articles/russi…

My name is Will McGugan. 👋 I am the creator of Rich and Textual, and the founder and CEO of Textualize. At the end of last year I took a year off to work on my Open-source projects and develop an idea that I believe will allow the terminal to eat some of the browser’s lunch.


First open source contribution to @IPythonDev . Here’s to many more!

Some Starlink terminals near conflict areas were being jammed for several hours at a time. Our latest software update bypasses the jamming. Am curious to see what’s next!

Citing Starlink jamming “near conflict areas,” @elonmusk says prioritizing cyber and jamming defense will delay @SpaceX Starlink v2 and Starship progress.
