Abgesehen von allem was mit dem "Reformpaket" der BReg falsch ist (so ungefähr das meiste), ist es erstaunlich, wie wenig denen klar ist, was das für ein politisches Todesurteil darstellt. Alle "Missstände", die Merz bisher kritisiert hat (hoher Krankenstand, hohe Arbeitslosenzahlen etc) werden durch diese Maßnahmen garantiert schlechter (sogar messbar). Nach Goodhart's Law werden Target-Kennzahlen normalerweise von obn gesetzt und von der Basis manipuliert. Hier wird die Kennzahl aktiv von oben manipuliert, aber in die Richtung, die dieselbe Partei eigentlich nicht will. Dümmer geht's kaum. Bitte schreibt euren Abgeordneten, dass sie dagegen stimmen sollen, insbesondere wenn sie von der SPD sind. Ich habs getan.

Do you use a software-based password manager (PWM)? Examples for a PWM include: Browser password storage, e.g. in Firefox, Chrome etc. or explicit apps like 1Password, Bitwarden, Keepass,... Pls boost for reach! #research

Gaming on Linux is easy: If the game is not on steam, all you need to do is install five different launchers and play around with about 10 different backends until it works.

Ich finde es immer wieder amüsant wie wir in Deutschland politisch einfach den Solar-Boom bewusst in die Tonne getreten haben und die Politik jetzt versucht, das fossile Autobusiness erfolglos zu retten. Hätten wir A, bräuchten wir B nicht. Jetzt haben wir den Schaden. Jobs gehen verloren, aber ohne Auffangindustrie. Und auf einmal müssen alle "mehr arbeiten" und "mehr Selbstverantwortung wagen".

Ich würde "danke CDU" sagen, wenn sie nicht die gesammelte Scheiße, die sie selbst jahrzehntelang angestaut hat, an der gesamten Bevölkerung auslassen würde.

It's a really sad development for many fedi users that "just google it" can't be used as an excuse for being a lazy piece of shit because you just can't google stuff anymore.

Mastodon ist ein gewinnfreies Franchise-Modell: Jeder kann eine Instanz aufmachen, wenn er die Mittel dafür hat. Die Aufmachung ist dieselbe, das Branding ist dasselbe. Wer sie kostenlos nutzen will, muss sich dem Hausrecht unterwerfen. Und jeder, der will, kann dich boykottieren.

#Dota2 thoughts: Hydra's Breath is a bait item for low-mmr sniper players. They think it's good, ignoring important protective tools like dragon lance in the process of getting it. I've seen so many lose because of this item (Turbo mode only though).

Everyone building things with code is an engineer, very much like a driver of a car, crossing a bridge.

Replying to on wien.rocks
@benchmark@wien.rocks absoluter Quatsch. Deutsche Ingenieursprodukte sind und waren Weltspitze. Chemie/Pharma ist ebenso einer unserer besten Sektoren. In Solar (wie im OP angedeutet) waren wir bis 2010 Weltmarktführer. Das Problem ist die Produktion zu kompetitiven Preisen. Asien unterbietet uns da einfach um Welten.

If I were a (seasoned) porn actor, I'd have great fun travelling to different catholic churches, confess, and chart out what they'd have me do. Script: "Forgive me, for I have sinned" "What have you done?" "I've had sex with 200 women before marriage"

Replying to
@livia@sciences.social in einem Land, in dem der Durchschnittshaushalt noch 50k Leitungen "in Ordnung"/"völlig ausreichend" findet, würde ich als Konzern auch keinen Anlass sehen, für Ottonormies mehr als 1G überhaupt anzubieten. Alles dazu zu aktualisieren, neue Strukturen in der Software etc. einzurichten kostet vermutlich nur, ohne nennenswertes Einkommensplus.

This text by @Koenfucius@mastodon.social is short sighted, and, dare I say, naive. Explaining surge pricing with "getting closer to the real value" is mystifying the whole process in a "invisible hand" kind of way. Yet, in practice, it is pretty easy to explain: 1) Surge pricing is an easy way of extracting more money from the same resource base, it maximises revenue across the demand/supply curve. 2) The reason people hate it is because it is inherently unfair. Access is not determined by supply, but by monetary resources which often are outside one's control to a large degree. 3) The real value of something is often way beyond the price of an object. Think about things you have to buy but hate doing so (clothes for example in my case). If clothes shops would start surge pricing, it would effectively render my personal value of clothes even less than before. Value is a shit construct, especially when including it in weird moderating mechanics into transactional processes. It would be easier to explain such processes with Desirability and Affordability graphs. https://koenfucius.substack.com/p/the-value-of-everything

One of my most disappointing moments in life was when I tried a sandwich recipe from a Donald Duck comic as a kid and it was really boring. I love(d) Donald, but learning about his sub-par taste changed me.

Kleinanzeigen ist einfach Rotz. Wenn man die App auf dem Phone hat und sich dann auf dem Desktop einloggen will, geht es nicht. Loggt man sich auf der App aus und wieder ein, auch nach cache wipe (selbe IP), geht es komischerweise doch, nachdem man nen 2FA Code per SMS (!) auf dasselbe fucking Phone (!) bekommt. Entweder deliberate Design choice, um die Leute auf die App (mit Werbung) zu knechten, oder einfach nur Unfähigkeit. Beides ist absolut unterirdisches Geschäftsgebahren.
