@Lamborghotti @erlangen_de Und die Schulstraße ist leider auch nur eingerichtet worden, weil letztes Jahr ein Kindergartenkind übersehen wurde und samt Laufrad unter dem Auto eingeklemmt wurde (siehe nn.de/erlangen/samt-…)

@Lamborghotti @erlangen_de Dafür gibt es eine Hol- und Bringzone eine Kreuzung weiter, wo man kurz parken kann und die Kinder entweder begleiten oder (für die Schulkinder) den Rest alleine laufen lassen kann...

Mit dem neuen Schuljahr startet mit der Liegnitzer Str. ein wegweisendes Projekt: Als Schulstraße mit geregelten Durchfahrtszeiten wird für eine erhöhte Sicherheit für Kinder im Umfeld der Schulen und des Kindergartens gesorgt: erlangen.de/aktuelles/schu…

Just. Wow. As we went over Mexico and the U.S. this morning, I caught this sprite. Sprites are TLEs or Transient Luminous Events, that happen above the clouds and are triggered by intense electrical activity in the thunderstorms below. We have a great view above the clouds, so scientists can use these types of pictures to better understand the formation, characteristics, and relationship of TLEs to thunderstorms.

BREAKING: An incredible "gigantic jet" – an extremely-rare type of upper-atmospheric lightning – was photographed from the International Space Station on Friday morning. This is the clearest photo we have EVER seen of a gigantic jet from above. Nichole Rhea Ayers is a major in the U.S. Air Force and a NASA astronaut. She launched to the International Space Station as a pilot of the SpaceX Crew-10 mission on March 14, and will be returning to Earth soon. On Thursday morning, July3, she captured an unbelievable photo of an ultra-rare GIANT JET. The International Space Station was over Mexico and the southern U.S. at the time. It looks like the instigating thunderstorm was happening somewhere near Sabinas in Coahuila, Mexico around 1:30 a.m. Central time Thursday. Gigantic jets are a subset of “blue jets,” which themselves are a type of TLE — or transient luminous event, often referred to as “upper-atmospheric lightning.” There are different types of TLEs, including red “sprites,” green “elves” and blue jets. Blue jets are the rarest. Elves and sprites occur high above thunderstorms, but jets bridge a key gap between a thunderstorm and the stratosphere high above. Sometimes they even reach up to the base of the mesosphere — the height at which meteors burn up! They begin as a cloud-to-air discharge that emanates out the top of thunderstorms, but immediately grow to MASSIVE sizes — up to 30 miles tall! They shoot upwards at speeds of 6 to 90 miles PER SECOND, but only last two or three tenths of a second. They are bright blue (almost like a neon sign, since they are plasma after all). The blue color is believed to stem from “excited” nitrogen. It’s believed that blue jets start as an ordinary lightning strike in the top of thunderclouds, where abundant positive charge is present. Sometimes there’s a negative charge in the clear air above. Instead of the negative charge flowing down to balance out the positive, sometimes the positive shoots upwards into the clear negative skies above. The result? A positive discharge that propagates upwards. Gigantic jets are even more spectacular. Emerging research suggests they begin as a discharge between negative charge in the mid-levels of the cloud and the positive tops of clouds. That leads to a *negative* “leader” of electricity that shoots upwards and escapes the cloud before it can actually discharge and “balance out” charge within the cloud. You can tell this one was a “gigantic jet” because of the reddish tops that resembles the stem of a carrot. That’s a sign the gigantic jet reached even higher altitudes — perhaps 50 to 60 miles above the ground. Atmospheric electrodynamicists (the fancy term for folks who study lightning) are learning about all sorts of never before-discovered lightning discharges. Most of what we know comes from photos like this! In recent years, scientists have coined new terms for curious, fleeting discharges — “trolls”, “pixies”, “ghosts” and “gnomes”. The existence of upper-atmospheric wasn’t known until July 6, 1989, when a researcher named R.C. Franz left a camera running overnight to capture the night sky. For decades, pilots had reported seeing strange red and blue flashes above thunderstorms, but it wasn’t until Franz obtained photographic evidence that scientists were able to delve deeper into the mystery. Nowadays, most of what we know comes from photographers who happen to get lucky — especially since the flashes usually last only a couple milliseconds. Ayers’ photo is truly a one-of-a-kind capture that will hopefully shed more light on how TLEs behave.

Aber wie war das noch, Hitler-Vergleiche werden langsam alt? 🤷

I don't know why so many Americans have this idea that Germans all feel guilty about WWII. I don't know anyone my generation or even my parents' generation who feels this way. I think this is a story that Americans are telling themselves. What is true is that at least the Germans I know feel a responsibility to make sure what happened in Nazi Germany doesn't happen again, not here, and not anywhere else. I certainly do. This is why we are scared by what we see happening in the United States. The concentration of power, the streamlining of opinions, the normalization of evil, and the populism to excuse it. These are all warning signs we were taught to recognize. Americans have this idea that the Holocaust happened in Germany because something is especially wrong with Germans. We're just somehow especially evil. This is why the bad guys in Hollywood movies are always Germans. This is why they make jokes about our supposedly military sounding language. I strongly disagree. What happened in Germany could have happened anywhere. It's just that Hitler was the first to exploit this weakness. He was a master of mass manipulation (probably strongly influenced by Le Bon's "The Crowd" -- worth a read if you don't know it). Now we have new masters of mass manipulation. And of course Germans worry about it. Don't confuse what we feel is our responsibility with guilt. Yes, ugh, "responsibility". That sounds terribly German, doesn't it. I'm sure you read this wiz a Schermen eksent. No, I'm not proud to be German. Why would I? I didn't do anything for it, I just happen to have been born to two Germans. But I am glad I am German because all things considered it's a good country. But if it was possible to just identify as Earthling and not belong to any country, that's what I'd want to be.

@angealbertini The knowledge about this eventually made it into my research about cutting portions out of ELF files on disk without needing to patch the code (github.com/rupran/shrinke…)

@angealbertini I was quite surprised to learn that ELF files have two views - the linking view and the loading view - and that those can differ. First encounter with this was a CTF challenge where all static debugging and disassembly tools showed a 'printf()' but the loader made it 'system()'.

What's your favorite file format challenge / trick / bug / surprise / work / art ? Bonus point if it's underrated or obscure!

Hmmm...

Booster starts in top right corner. Watch to the end. Sound on

Mechazilla has caught the Super Heavy booster!

BREAKING: SpaceX just successfully caught its Super Heavy rocket booster in mid-air on its first try! This is the first time anyone has accomplished such a feat, marking one of the most significant engineering achievements in human history. Congrats @SpaceX team! 🚀

Nächsten Samstag ist #csd in Erlangen und die FAU ist auch mit einem eigenen Stand am Start.🌈 Wir freuen uns auf alle, die uns vor Ort besuchen kommen. ⏰14.9., 13-17 Uhr 📍Besiktas-Platz Mehr Infos zum CSD in Erlangen: makeyourtownqueer.de/csd-erlangen/

@splcconf @chrdietrich Wrong Christian, the right one is @stettberger 😉

#SPLC2024 Session Variability Implementation II Should I Bother? Fast Patch Filtering for Statically-Configured Software Variants (Research Track) by Tobias Landsberg, @chrdietrich and Daniel Lohmann

WLAN mit Öffnungszeiten... Das ist mal wieder #Bayern in Höchstform 😑

I don’t think it’s too early to call it: this will be the largest IT outage in history

Something super weird happening right now: just been called by several totally different media outlets in the last few minutes, all with Windows machines suddenly BSoD’ing (Blue Screen of Death). Anyone else seen this? Seems to be entering recovery mode:

👀

@halvarflake Awesome, congrats and thanks once again for building this!

Yaaaay!!! #issuecomment-2150480058" target="_blank" rel="nofollow noopener">github.com/open-telemetry…
