"Drafting" by XKCD comic (Fediverse mirrors @xkcd @xkcdbot ) - Drafting works for measly subsonic vehicles (and birds) in close formation. But for rockets, it doesn't help much, especially when all the rockets shut off for stage separation/ignition and set themselves up for practically 100% collision risk. "What were you doing there?! I had to drop my first stage and keep going!" xkcd.com/3093/ #space #rocketry #physics #oops #WTF #humor

XKCD comic #3093 "Drafting" https://xkcd.com/3093/

transcript & explanation from ExplainXKCD https://www.explainxkcd.com/wiki/index.php/3093:_Drafting

transcript:

    [A rocket with two boosters is launching. A smaller rocket is following the first rocket very close, inside its exhaust plume. The first rocket has a tow-stage core, and two boosters. It produces 3 big flames. The second rocket does not have boosters. It produces 3 small flames.]

    [Caption below the panel:]
    Aerospace tip: Although the technique reduces atmospheric drag for many types of vehicles, you should never try to improve rocket launch efficiency through drafting.

title/mouseover text:
A 5% efficiency gain at the cost of a 99% efficiency loss

explanation:
Drafting is an aerodynamic technique where one moving object follows another one closely to reduce drag by using the first objects splitstream. It is used in various sports, most prominently cycling.

The comic explores the idea of using drafting for rockets and states that while it theoretically works, it isn't really recommended. The title text gives more details on this, claiming that there is an efficiency gain of 5% through drafting via the general mechanism, it also comes with a 99% loss (which isn't explained in detail).

Not sure if this is the funniest thing ever or the most frightening thing ever....

I still have like Clippy PTSD from my high-school/College days

But someone went ahead and made an AI chatbot, with a Clippy front-end.

Sat in Selco Builder Merchant cafe and holy fook. Someone played the most inflammatory and racist "podcast" on their phones speaker.
Some well spoken English lady on about "the immigrants" dismantling the police, "taking our big dogs we have to defend ourselves" (the XL Bully ban)and building an army to attack "us". When they attack they will "go for the women and children" and "they are angry and will be savages".

Wtf is this. Why does someone listen to that, let alone post it.

#racists #wtf

Elon dumped $300M lobbying for a bill that kills clean energy, slashes EV credits, & will force Tesla into losses + mass layoffs by 2026. It directly hurts the company he built. $TSLA is somehow up 2.5%. I still love Tesla cars—but seriously, what the actual f***. 🤡📉 #Tesla #Musk #CleanEnergy #WTF

Tesla (TSLA) is badly affected...

Bin gerade raus aus dem deutschen Pavillon der #expo2025 in #Osaka und muss sagen, der war sehr enttäuschend.

Präsentiert wird eine grüne Vision unseres Lebens mit Flugtaxis vom Pleite-Startup volocopter, einer Mercedes e-Auto Vision die bei #BYD längst Realität ist und Züge die mit Wasserstoff fahren sollen, obwohl der Strom dort schon anliegt.

Dann schaue ich Nachrichten und wir wollen Gaskraftwerke bauen weil #Klimaschutz überbewertet ist.

#WTF

😑

OF COURSE it does NOT support WSL2, this was so clear 👏

Are these companies ignorant, lazy? I don´t get it.

They release one of the best LLMs on the planet but still ignore the fact that most people on earth use #Windows —NOT Linux, NOT Apple.

They do pretty well by ignoring this tiny little fact..... unbelievable......🙄

github.com/anthropics/claude-c

and with "they", I mean: also #jetbrains itself ignored WSL2 as they released junie.... crazy.... just crazy..... 😒

Unfall in Duisburg: E-Bike-Fahrer stößt mit Lieferfahrzeug zusammen und verletzt sich schwer

Wie dämlich.
Die Überschrift muss heißen:

Lieferant nimmt Radfahrer die Vorfahrt und verletzt ihn schwer
