walskion Dolosse – a South African invention used over the world

Ok I stand corrected these are NOT tetrapods. Sorry for the confusion

walskion Dolosse – a South African invention used over the world

In Germany (on the island Sylt) they recently removed all of these structures again after decades of them being a staple on Sylt's beaches. They were found to have no positive effect on protecting their shores.

I'm having a hard time to find a good source to quote but look for: "sylt tetrapoden" if you want to dive deeper.

walskion TLA+ Modeling Tips

> TLA+ is a formal specification language developed by Leslie Lamport. It is used for designing, modelling, documentation, and verification of programs, especially concurrent systems and distributed systems. TLA+ is considered to be exhaustively-testable pseudocode, and its use likened to drawing blueprints for software systems;

walskion Penpot: The Open-Source Figma

Does it really matter if in real-world-use 99% of the users never hit any limit? And I cannot blame anyone to use "unlimited" instead of "fair use, with reasonably large limits so that you will (probably) never see any restrictions in your use of the product"

This is so cool! High five to you Armaan :) I will show the game and the backis stories to my 7 year old tomorrow. There is a decent chance you'll become his new hero. Hope you continue to put out more cool stuff into this world. It definitively needs it! Greetings from Germany

walskion A pretty visualisation of the European power grid (2022)

Form their website:

> The math behind it is real, and it uses the same calculations that real grid operators use to keep the lights on. However, the amount of power that each power plant actually produces depends on the price they offer. This price varies wildly from hour to hour, and neither the price nor the power amount is publicly available.

> Instead, pypsa-eur makes assumptions on prices for solar, wind, coal, nuclear, etc. based on historical averages, and then runs an optimisation algorithm to cover all consumption for the least cost of production.

walskion Relatively cheap vservers (GER hoster, now with DC in VA)

We've been using their products in Germany for a while now and they do their job just fine. I've been on the lookput for a similarly priced hoster in the US a while back and couldn't find one. Today netcup announced they are opening a data center in Virgina, so thought it might be worth sharing. I've no affiliation with netcup in any way (other than being a customer for years now).

walskion Rsh: Ruby SHell

:D Great! What are you up to nowadays?

walskion Rsh: Ruby SHell

(slight ot, sorry!) This brings back great memories of one of the best assignment from my college time: We had an "Agile web development" course (~2007) with a precursory Ruby 101 workshop as well as a pre-course assignment to "create a shell in Ruby". It was such a joy to hack on this and learn that way. It was clearly wayyy too vast of a task to ever _complete_ it, but I learned so much Ruby there and couldn't stop working on the project. Thanks Carsten Bormann for being a great teacher!

And thanks op for reminding me of this :)

walskion First flight of the Airbus A321XLR with up to 4700 NM range

Yes, but a 747 wide-body is a lot larger and hence needs a hub-and-spoke route network to fill these giant planes at a hub to make the flight viable economically. The narrow-body A321 can be filled with ~200 passengers (compared to almost 500 pax capacity for a 747-800) at many smaller airports, making long-distance point-to-point routes from these airports viable.

The concept of "Readme Driven Development" [1] seems similar, but smaller in scope. I've actually found it very pragmatic/productive to, especially for smaller libraries, start with writing the Readme.
