Das erste Grazer Fedicamp

Am Samstag hat in Graz zum ersten Mal ein Fedicamp stattgefunden – ein Barcamp zum Theme Fediverse. Marc und ich haben es organisiert.

Am Abend waren, glaube ich, alle zufrieden – auch wenn das Event ganz anders abgelaufen ist, als es geplant war. Wir wollten vor allem Menschen ansprechen, die das Fediverse noch nicht kennen. Tatsächlich sind nur Leute gekommen, die sich sehr dafür interessieren, darunter André Menrath und Alex Kirk, die Komponenten des Fediverse weiterentwickeln […]

Ein mutiges Video von #Telekom und Miniatur #Wunderland zur #Klimakatastrophe sorgt aktuell für Furore.

In dem ganzen, beeindruckenden Clip wird nur ein Satz gesagt bzw. von einem Mädchen gerufen: "Warum schaut denn niemand hin?".

Es ist die Schlüsselfrage der #Erkenntnistheorie, der Frage nach #Wissenschaft und #Wahrheit gegenüber der menschlichen #Psychologie. Eine Chance, auch über den #Fossilismus und die #Karbonblase nachzudenken!

Recharge: "French city drops order for 51 hydrogen buses after realising electric ones six times cheaper to run." In the French city of Montpellier and its environs, a two-yr-old project to operate a fleet of hydrogen buses has just been canceled. The "€29m...Montpellier Horizon Hydrogen project—which included the construction of a small solar-powered green-hydrogen plant—had been announced by EDF subsidiary Hynamics in December 2019." Funding of €18m was sourced from regional, national + European funds, plus another €8.9m from the French sovereign fund Caisse des Dépôts. In US dollars, this totaled over $29 million at current exchange rates. "But Michaël Delafosse, the mayor of the Montpellier Méditerranée Métropole (an administrative region centred on the city of Montpellier)...elected in June 2020, last week decided to cancel the project on the grounds of cost." The problem was that all that funding supported only the initial investment, not the ongoing operations. "Green hydrogen is an inherently inefficient and expensive solution for road transport as it requires renewable electricity for electrolysis to create the H2, more power to compress the gas, which needs to be stored in large tanks, an expensive filling station is required to pump the stored hydrogen into a vehicle, where a fuel cell converts the H2 back into electricity." Simply put, it is 'much more efficient and cheaper to pump the renewable electricity directly into a vehicle battery.' For road transport at most scales, I have decided that my infatuation with hydrogen was only a passing fancy. As an aside, "China is currently the world leader in electric buses, with more than 500,000 on the country's roads." And I salute the electric buses we have in our fair city of Bellingham.

The image is a meme highlighting a perspective on mathematical simplification. The top part of the meme displays a complex mathematical expression: (a-x)(b-x)(c-x)...(z-x), labeled as "Simplify." Beneath this, there are two parts labeled "Before you realize it" and "After you realize it." The first part depicts an image of a distressed Pikachu with its tongue sticking out, likely representing feelings of confusion or difficulty when first encountering the complex expression. The second part shows a more relaxed and comforting Pikachu, signifying relief or understanding after simplifying the problem. This meme vividly illustrates the emotional journey one might experience while dealing with complex mathematical expressions.

I've been seeing hate on NASA lately, being bought into by leftists even, and I just want to point out something very important:

Musk has hated NASA for a *long* time. There is a reason it is being attacked, and a reason public opinion is being swayed against NASA: It *keeps SpaceX in line* more than anything else.

NASA is being seen as "competition" to SpaceX, as the obstacle in his way. It has been like this for quite some time, and now, with DOGE and other things, he can do something about it.

I would like to point out a few things:

1. SPACEX IS NOT CHEAPER
They boast they can "do what NASA does for 10% the cost!" Sure, it's easy when you did none of the R&D.
SpaceX saved on:
Landing tech: DC-X project in 1991-1996
Tank structure: Shuttle SLWT tank, 1998-2011
Merlin Engines: direct descendant of the Fastrac Engine, 1997-2001.

Those three things alone saved SpaceX over 90% of the R&D costs. It's easy to "appear" cheap when you're using off the shelf tech someone else (NASA!) developed.

2. NASA IS GREAT FOR THE ECONOMY!
For every $1 spent on NASA, $8 is put into economy. Its stupid to not invest in that kind of ROI! 800%! At times, its ROI Has been 1600%!

Simply put, if you defund NASA, the economy would shrink so much you would actually have to RAISE taxes to make up for the lost revenue, and without its existence we would be 30 years behind in technology and the quality of life for everyone would be much lower. Science and research is GOOD for society, it's the fuel for all progress.

3. WHAT HAS NASA DONE FOR ME?! (Surely you just mean NASA is good for tech & science folk....)

Nope! Good for all!
Ever have an MRI or CAT Scan? They wouldn't exist without the Apollo program! The software that made them possible was originally written to analyze lunar photography.

Low power digital x-Rays was planetary body research.

Heart pumps are modeled after space shuttle turbopumps.

The software that designed your car was originally written to design spacecraft!

Who do you think pioneered all the early research into alternative power like solar panels, hydrogen fuel cells, and durable batteries? NASA!

NASA developed tech and satellites is also what improves agricultural yields while reducing the needs for water, fertilizer, and pesticides.

Do you really think Musk gives two shits? No. He wants the money, he wants to let SpaceX run amok without any oversight for safety, without any "competition".

All fights are important, but do realise that this one is a huge thorn in his side, and one that is keeping a huge problem from ballooning and swallowing us all whole.

Do not be fooled or swayed by lies, of tactics meant to divide, of things being done to make you be angry at NASA. If he can make you hate NASA, he won.

Expect far more space junk to fall, the night sky to be ruined by satellites, and the loss of all things good that proper research and design does for humanity and gives back to the world. Not to mention: enjoy seeing the horrible things he can accomplish fully unchecked.

ETA: Now that you know, call / fax / email your senators and reps, and whatever else too! Boosting gets people thinking, but thinking is not action!

The A1 test stand at Stennis, which on this day did a full burn test of the redesigned RS-25 engine. 

The A1 is a vertical firing single position stand, meaning it holds one rocket engine at a time in an upright position with thrust directed downward. You can see the RS-25 engine in the stand, there is a truck and a large van for some scale. 

The NASA logo (meatball) is proudly displayed on the upper right of the stand.

Kommunikative Probleme der Neuzeit:

"Digitalisierung" sagen, aber "Automatisierung" meinen

"digital" sagen, aber "online" meinen

"online" sagen, aber "cloudbasiert" meinen

"cloud" sagen, aber "im Browser bedienbar" meinen

"KI" sagen, aber "Algorithmus" meinen

"smart" sagen, aber "messbar" meinen

Kein Wunder, dass ständig falsche oder zu kurz gedachte Entscheidungen getroffen werden.

TIL: Mein #CardTAN-Generator schaltet sich relativ rasch nach der Benutzung (TAN-Generierung zum Einloggen bei der Bank) wieder ab. Zumindest das Display ist leer.

Allerdings muss man nicht - so wie ich bislang falsch dachte - zur weiteren Nutzung nicht nochmal die Karte stecken und seinen PIN eingeben.

Stattdessen einfach Karte stecken lassen und zB auf "OK" drücken und schon geht's ohne weiterer Authentifizierung weiter.

Beim Rausziehen der Karte startet man in jedem Fall von vorne.

For the 4th year in a row, my all-sky camera has been taking an image of the sky above the Netherlands every 15 seconds. Combining these images reveal the length of the night changing throughout the year, the passage of clouds and the motion of the Moon and the Sun through the sky. #astrophotography

This image shows the hourglass shape of the nights shortening and lengthening from winter to summer and from summer to winter, passing clouds, the Moon passing through the night sky every month (diagonal bands) and the Sun climbing higher in the sky during summer.
