#OTD in 1887.

L. L. Zamenhof published Unua Libro, the first publication to describe Esperanto, a constructed international language.

First published in Russian on July 26 [O.S. July 14] 1887, the publication of Unua Libro marks the formal beginning of the Esperanto movement.

Okay, so this took me down a weird path where somebody asked why I don't just use the command line for a quick timer and I thought "sleep && beep && beep", so I tested and discovered a series of weird things:

- The unix `beep` tool does not work in Windows Services for Linux (WSL1)
- However, the act of `beep` *failing to work and printing an error message* causes Windows Terminal to play a beep
- Therefore, the unix `beep` tool works in Windows Services for Linux (WSL1)

to be a successful community led open source project maintainer you need to:
- write code (i guess)
- be good at 1-1 communication
- be good at mass communication
- be good at writing
- know your limits
- know when to stop and learn
- know how to delegate
- know how to establish and keep good interpersonal relationships
- know how to recruit people
- know how to teach people
- be *really* efficient at teaching people, since most will drop out
- track concerns faced by both novices and experts

She analysed brand new ENZO simulations to predict the integrated background of γ-ray and neutrinos from shocks, AGN and star formation , from z=0 to z=3.

Here is the evolution of hadronic γ-ray emissions in the simulated volume, for a few snapshot.

Switzerland now requires all government software to be open source https://www.zdnet.com/article/switzerland-now-requires-all-government-software-to-be-open-source/ by @sjvn

Switzerland is one of the world's leading #opensource countries; now, if only the United States could follow its lead!

Today is World Emoji Day, so here's a reminder that we have 🚳 and 🚷 but not

Well, it looks like Matilda Jones, aged 7, is the new ruler of Britain, sorry I don't make the rules.

So Esquire put my 31-year old (!!) AMMONITE on it's 75 Best Sci-Fi Books of All Time list: "Gripping and gutsy, rich in layers of feminist and queer thought, Ammonite gleefully throws a stick of dynamite into the sci-fi firmament."

We've got this cheap egg cooker that plays the loudest, most terrifying alarm you've ever heard when it's done cooking. My wife requested that I make it "less aggressive" so I hacked it into the most gentle egg cooker of ALL TIME

(warning: probably loud)

computers used to scream when you connected them to the internet. this was correct

For a long time people thought noble gases were too snobbish to form compounds, but in 1962 Neil Bartlett produced xenon hexafluoride.

Most xenon compounds involve fluorine, chlorine and oxygen - elements so aggressive they ignore the standoffishness of this noble gas, slap it right on the back and say "hey, pal! I'm moving in!" But as a result, some of these compounds are dangerous. Xenon trioxide and xenon tetroxide are explosive. Xenon oxytetrafluoride, shown here, is extremely reactive, and it forms hazardous and corrosive byproducts when mixed with water.

A much more mellow chemical is tetraxenonogold - the first discovered compound involving a noble gas and a noble metal! But to make it, you use fluorine.

As far as I can tell, all these xenon compounds are created by chemists just to provide interesting Wikipedia articles for me to read while sipping coffee in bed:
