Fluggeschwindigkeiten, IAS, TAS, EAS, CAS, Mach by wabis wabis (Walter Bislin's Blog-De)
Dieser Artikel befasst sich mit den verschiedenen Fluggeschwindigkeiten, deren Berechnung aus im Flug gewonnenen Messdaten und deren Beziehung untereinander.

Das ist so wahnsinnig gut erklärt. Ich komme immer wieder auf http://walter.bislins.ch/blog/index.asp?page=Fluggeschwindigkeiten%2C+IAS%2C+TAS%2C+EAS%2C+CAS%2C+Mach zurück. Und dabei fliege ich nicht mal im echten Leben – und habe es auch nicht vor o0

Indexing in MySQL by yahwho (yahwho.org)
I have been working a lot with JavaFX recently and it’s been a while since doing any SQL work. After loading my project and running a few test commands I was pretty shocked to see that the SELECT statements were taking almost 15 seconds to produce a response! Thankfully I quickly remembered I need...

Indeed. Always worth to take a closer look at indexes when SQL queries are too slow 👍

A Very Silly Workaround to Verify the @scalzi Account on Twitter is Actually Me, John Scalzi by John ScalziJohn Scalzi (whatever.scalzi.com)

This is why especially the IndieWeb people are adamant about that everyone should be their own identity provider on the net and not give that role away to any silo|3rd party. Yes, a domain costs (just like a phone number). Even if it just holds a single page referencing “official” profiles. I’m aware that this isn’t an identity check but it’s enough to tell profile equivalence and this is the more important part.

BTW: Love your books 🤓

Testing my “all-in-one” “IndieWeb” plugin for WordPress with the new 6.1 beta and Twenty Twenty-Three. Seems to work OK, but I’m wondering why my “site doesn’t support the core/post-author-name block.” Like, I knew about the post author block … Of course, you’ve got to install Gu...

This is _very_ exciting @Jan. Would love to give this a try but I’m totally at capacity right now 🙁 Anyway, starred. Keep it up!
