Claude's usage page said my free limit reset "Expires Oct 22", no time, no time zone. So I planned to use it before midnight. On both my Max 20x accounts it vanished hours earlier, while it was still Oct 22 in UTC and PT. Fin won't escalate. Please show the time! @ClaudeDevs

@migueldeicaza a certificate authority trusted by basically every computer on the planet issued intermediate certificates with 1-byte private keys. anyone can trivially forge a cert for any domain that unpatched apps will see as valid.

New Outlook: Ctrl+S on a calendar event saves AND closes it – and appointments don't autosave. Editing long entries = save, reopen, repeat. One crash and your work is gone.

Classic Outlook got this right. Upvote if it bugs you too:

Worth watching: llama.cpp just added its own GPU cache for MoE experts, and multi-token prediction for Flash-Next is in the works. The gap should shrink—no extra engine needed. #llamacpp #LocalLLM

Qwen3.8-Flash-Next (125B MoE) on a laptop? Community benchmarks show Strata at ~50 tok/s on an RTX 4090 Laptop—my Qwen3.8-27B manages ~20. One caveat: the Windows .exe is hand-built and unsigned, with no CI, so you can’t verify it matches the source. Build it yourself. #LocalLLM

when I was a kid this was science fiction. i've watched AI type for years, but hearing it and seeing what it made is a whole different level.

i asked @claudeai opus 5.5 to introduce itself, however it wanted without any token usage restrictions and access to any api it wanted. it decided to write a song, make a video, visualize itself and give an interview behind the music.

it also wrote this thread 🧵

@vineerpasam Fable 5.1. Almost daily. Today it told me that we don't yet have a dynamic grid and one would have to be build... I just told it to look again. Other stories in my https://t.co/qZOwGKO7gx

Used Claude Code to add metadata from Google Takeout (date photo taken, GPS ...) to image files and move them to OneDrive. Mass deletion in https://t.co/kQsP7EOke3 was a nightmare. Browser refresh after every delete helped. Friend happy!

@AmazonHelp Nein, Marketplace war NICHT involviert und mein Verständnis daher eher gering...

LG Gram 17 17Z90TL-G Notebook direkt bei @amazonde für 1.489 € bestellt; geliefert 16Z90TS-G mit nur 16 GB RAM, 1 TB Storage. Rücksendung beantragt; angeblich keine Ersatzlieferung möglich. Amazon bietet 17Z90TL-G für 2.214,88 € an (kein Marketplace). Go figure ...

Update zum WISO MeinBüro EÜR-Bug: Buhl bestätigt die Ursache – Konto 470 hat im 2025er-Modul keine EÜR-Zuordnung mehr, Anlagegüter fallen lautlos raus. 2024 war noch korrekt → Regression. 470 bleibt trotzdem ohne Warnung wählbar. Workaround: Art 490. https://t.co/JPfi1DRrTL

⚠️ WISO MeinBüro Desktop: Der ELSTER-Export der EÜR 2025 verschluckt Anlagegüter der Art 470 (Computeranlagen) samt AfA – lautlos, Gewinn zu hoch. Prüft Zeile 33 gegen Konto 4830! Workaround: Art auf 490. Ticket 2527174. Details: https://t.co/M4pvvKRlDN

Why does an AI lose the thread mid-conversation? Why does it sound confident when it’s guessing?

That’s what https://t.co/qZOwGKO7gx is for: hands-on labs, a plain-language glossary and a real, tiny GPT in slow motion. AI, in context. In English and German.

[Harald Mühlhoff @HaraldMuehlhoff]

Warum verliert eine KI mitten im Gespräch den Faden? Warum klingt sie überzeugend, wenn sie rät?

Dafür gibt es jetzt https://t.co/qZOwGKO7gx: Labore zum Anfassen, ein Glossar in Klartext und ein echtes, winziges GPT in Zeitlupe. KI – mit Kontext. Deutsch und Englisch.

I want you to meet https://t.co/BOOQXoLUBF. It's been in my mind since I went to @TonyRobbins Mastery University over 30 years ago. Using @claudeai it finally became reality and I'm thankful for that. It doesn't use cookies, tracking ... Your data stays with you. Enjoy!

How to say you don't care without saying you don't care, @MicrosoftEdge ...

My icon for https://t.co/BOOQXoLUBF is fine everywhere; just not in the Edge dialog if you want to open the app from the browser version.

@JorgeBriones101 Went from Opus 4.8 (1M) to Opus 4.8 (256K) after update; BUT I can select Opus 4.8 - and it has 1M token.

[Harald Mühlhoff @HaraldMuehlhoff]

@JorgeBriones101 Yes. With the last update. Gladly I'd just finished my work for today. Let's see where this takes us...

@emreyz_ Went from Opus 4.8 (1M) to Opus 4.8 (256K) after update; BUT I can select Opus 4.8 - and it has 1M token.

[Harald Mühlhoff @HaraldMuehlhoff]

@emreyz_ Yes. Same here.
