🚨 Europas Behörden gehen offline. Das wird sehr sehr sehr übel enden.
Zwei kritische Lücken in PHP. Codeausführung aus der Ferne, ohne Anmeldung oder Nutzerinteraktion. Betroffen sind laut BSI potenziell alle Versionen ab PHP 5, also zwanzig Jahre Code.
Das BSI stuft die Lage als kritisch. Betroffen sind u.A.:
→ Bundespolizei, Bundesinnenministerium, Zoll
→ Robert-Koch-Institut
→ Charité Berlin, Klinikum Nürnberg
→ Berliner Feuerwehr, Berliner Tafel
→ Universität Potsdam, weitere Universitäten
→ Hessische Landesregierung, Thüringer Landesverwaltung samt Landespolizei
→ Bayerische Behörden, Landratsamt Rhön-Grabfeld, Landkreis Dahme-Spreewald
→ Städte Dresden, Mainz, München und weitere Kommunen
Und am selben Tag patchten Node.js zehn Lücken, vier davon kritisch, sowie Go.
Jetzt der Teil, über den kaum jemand redet.
Die Lücken lagen über ein Jahrzehnt unentdeckt im Code. Gefunden wurden sie von OpenAIs GPT-5.6 Sol (!!!). Wiz nennt sie die schwerwiegendsten Lücken, die je mit dieser Technologie gefunden wurden.
BRISANT IST: Das Weiße Haus wusste seit Freitag, dem 16. Oktober, Bescheid. OpenAI koordinierte die Offenlegung mit CISA und dem Office of the National Cyber Director. Fünf Tage, in denen eine Regierung wusste, dass drei Viertel des Internets offenstehen, und die anderen nicht. Am Ende ging die Sache durch ein Leak vorzeitig raus, deshalb JETZT der Notfallmodus.
Genau hier zeigt sich, was es praktisch bedeutet, keine eigenen Modelle zu haben - Wovor ich nun seit Jahren warne!
Diesmal ging es noch gut aus. Doch jeder der sich in Europa jetzt nicht auf sehr düstere Zeiten vorbereitet, bewegt sich auf Glatteis.

Non si può parlare dell’#Europa senza menzionare il cristianesimo. Robert Schuman ne era ben consapevole quando affermava: «Il cristianesimo ha insegnato l’uguaglianza di natura di tutti gli uomini, figli dello stesso Dio, redenti dallo stesso Cristo, senza distinzione di razza, colore, classe o professione. La legge universale dell’amore e della carità ha fatto di ogni uomo il nostro prossimo, ed è su di essa che da allora si basano le relazioni sociali nel mondo cristiano». #ViaggioApostolico #Francia vatican.va/content/leo-xiv/i…

I watched Once when Netflix was a mail order DVD rental business. Immediately after, I got off my couch, went to the mall, and bought the CD moments before HMV was closing. He was a beautiful poet who spoke directly to my soul, esp in my darkest times.

“The Fields of Athenry” - Glen Hansard with Paddy Reilly of The Dubliners teapaw.org/RBSN_ZHLR/status/20824…

Sometimes I would wonder if Glen Hansard really existed….
Seriously, he was such an angelic presence… not otherworldly…in fact, very present this presence…
A smiling rascal if you needed him to be… this most musical and mischievous archangel of Ballymun… no airs, plenty of graces...
Of course, Glen was the shining star of the Christmas Eve busk… sometimes the only one reminding the rest of us that Christmas began with a refugee born in a manger, which is hardly a step from living on the street.
To be utterly yourself by being more interested in others - a clue for any of us trying out different personas. He really was who you thought he was. He could never walk by a person living rough without checking they were OK… and more than that, he worked very hard so that less people had to live on the streets in the first place.
When the crowds got bigger and for safety’s sake Glen had to agree to move the busk to a stage kindly provided outside The Gaiety Theatre, he would say 'we’ll give it our best but it’s not a busk if we’re not on the street!’ …because that’s who he was - a performer at eye level in any situation. The stage was a separation he wouldn’t recognize. Of all the grand and gigantic venues he and The Frames played, you sensed the street was his most favoured place to perform. And street people, his favourite audience.
Voice of the streets. A choir of angels in one man. The rest of us blessed to stand there beside our very own and very earthed Angel Gabriel… All of us welcome in his choir, whatever shape or form.
….and I’m telling myself this morning that if he never existed, then he can never cease to exist. For me, he will always be everywhere I see a coin spinning into an open guitar case.
May you rest in the peace you gave to so many.

A NOBEL WINNING PHYSICIST ARGUED THAT NO AI, NO MATTER HOW POWERFUL, WILL EVER TRULY UNDERSTAND A SINGLE THING IT SAYS. HIS REASON IS NOT COMPUTE OR DATA -- IT IS A MATH THEOREM FROM THE 1930s THAT SAYS SOME TRUTHS CAN BE SEEN BUT NEVER COMPUTED
81 minutes with Roger Penrose -- the Oxford physicist who won a Nobel for his work on black holes and general relativity.
-> His claim: whatever consciousness is, it is not a computation. A machine following rules can imitate understanding, but never actually have it.
He builds it on Gödel: a human can just "see" that certain statements are true, even though no algorithm can ever prove them. That seeing, he argues, is non-computational.
If he is right, understanding is not something you scale into. You can stack a trillion parameters and still have zero awareness underneath.
Which cuts straight through the AI moment. Everyone assumes bigger models will eventually "wake up". Penrose says that is a category error -- more computation is still just computation.
You thought intelligence and understanding were the same thing. This is the conversation that pulls them apart.
Save this. It is the sharpest case against the hype ↓
A DEVELOPER STOOD UP AT A CONFERENCE AND APOLOGIZED TO THE ENTIRE INDUSTRY FOR ONE LINE OF CODE HE WROTE IN 1965. THAT SINGLE DECISION HAS SINCE CAUSED CRASHES, BREACHES AND ROUGHLY A BILLION DOLLARS OF DAMAGE AND YOU HIT IT EVERY SINGLE DAY
61 minutes from Tony Hoare -- the man who invented quicksort, won the Turing Award, and passed away in early 2026, leaving this as one of his most honest talks.
-> His confession: he added the null reference, letting any variable secretly mean "nothing", simply because it was easy to implement.
That one shortcut became the null pointer, the undefined, the None -- the crash waiting inside almost every program ever written.
He calls it his billion-dollar mistake, and he is not exaggerating. Whole classes of bugs and security holes trace straight back to it.
And this is the deeper lesson under the AI rush: the easy shortcut you ship today becomes the landmine everyone steps on for the next 40 years.
You thought null was just part of how code works. This is the talk where the man who made it tells you it never had to be.
Bookmark & Watch this one. You'll never type null the same way ↓

I'm from Central Italy.
The Italians I know rarely spend their weekends in the hotspot cities.
Not Florence. Not Rome. Not Siena. They drive an hour east, or south, to towns no foreign list ever mentions.
Central Italy is the most concentrated cluster of beauty in the world.
9 underrated towns where the piazza is yours, the trattoria is real, and the Renaissance still feels personal.

Goosebumps! People often ask, is Shakespeare still relevant? Here is a great example, from the Steven Colbert Show, in which Sir Ian McKellen delivers an extraordinary speech. Shakespeare’s words are timeless, urgent and important.

"My algorithm has always been: You put smart people together, you give them a lot of freedom, create an atmosphere where everyone talks to everyone else. They're not hiding in the corner with their own little thing. They talk to everybody else. And you provide the best infrastructure. The best computers and so on that people can work with and make everyone partners." Jim Simons
