On leaving the Guardian: dreams of digital journalism https://t.co/CH92FlbxiH

@simpsoka I agree, and we're working on it!

[Sébastien Cevey @theefer]

@thameswater Thanks, it looks like it was finally fixed overnight.

[Sébastien Cevey @theefer]

@thameswater Any plans to address this huge water leak on Church Road (Leyton) which has been pouring tons of clean water out since at least Sunday?

@timzaman @demishassabis @GoogleAIStudio Theme Park was the first game I ever bought as a child. 6 floppy disks!

Funny journey to end up working for DeepMind and enabling to recreate this classic!

Extraditing people who fled their ancestral home to seek a better life for their family seems like a sure way to encourage humane morale values, stop the growing latent racism in this country and heal its soul.

I just got violently physically assaulted on the train today by a white British man, but happy to hear that Labour has identified the source of all the country’s ills to be “illegal migrants” and “asylum seekers” (conveniently conflated).

@benln Cool! Is there a booking process and any more details?

[Sébastien Cevey @theefer]

Profoundly shameful.

I really enjoyed Vercel but will now work on finding alternatives.

Enjoyed my discussion with PM Netanyahu on how AI education and literacy will keep our free societies ahead.

We spoke about AI empowering everyone to build software and the importance of ensuring it serves quality and progress.

Optimistic for peace, safety, and greatness for Israel and its neighbors.

Anthropic Image Gen → Claude Monet
Anthropic Music → Claude François

[Alex Albert @alexalbert__]

We’re unifying all of our developer offerings under the Claude brand.

- Anthropic Platform → Claude Developer Platform
- Anthropic API → Claude API
- Anthropic Docs → Claude Docs (available at https://t.co/JwXzp3JDHb)
- Anthropic Help Center → Claude Help Center (available at https://t.co/URCoNtH0Ns)
- Anthropic Console → Claude Console (available https://t.co/90Mwykct4F and at https://t.co/oSRdcFZBAc until 12/16/25)

You'll see updated naming across our sites and documentation, but your technical implementation stays the same.

@__apf__ Exciting news, welcome to GDM!

[Sébastien Cevey @theefer]

@simonw @bunnypixel8 I often explain this by saying that we have increasingly good AIs for coding, but not yet for engineering.

[Sébastien Cevey @theefer]

@auchenberg I'm pretty sure we have a couple more.

Gemini CLI is here! Our most powerful open-source CLI that brings Google's Gemini 2.5 models directly into your terminal! With unique features like hierarchical memory (context), self-correcting file edits, and secure sandboxed tool execution.

💡 Hierarchical Memory and instructions from GEMINI md files.
🛠️ Bulit-in tools for filesystem, shell, MCP servers, and new shareable custom extensions.
📄 Multi-modal context, understands images, PDFs, and live web search results.
🔒 Supports secure tools via container sandboxes (Docker, Podman, or macOS sandbox-exec)
📈 Switches models automatically (e.g., pro to flash) to bypass API rate limits.
📊 Built-in Observability with OTEL traces, metrics, and logs.
💾 Save and resume conversations: persistent history across sessions, isolated per project.
💡 Git-Aware Context, the @ command respects .gitignore, --yolo flag to auto-approve
🤗 Native Windows support, no WSL required and Open Source under Apache 2.0!

Get started `npm install -g @gemini-cli/cli`

@ntaylormullen Amazing work, congrats on shipping it! 🚢🎉

people are using veo3 to bring history to life in the form of vlogs 🤣

@GergelyOrosz I know there are but I'm not sure if they are willing to publicly advertise it

[Sébastien Cevey @theefer]

@scottdwitt @mbleigh My point was that in my experience, fast & iterative development with a tight validating feedback loop is a safer and more efficient way to make progress towards goals than designing larger solutions in the abstract prior to implementation.

[Sébastien Cevey @theefer]

@scottdwitt @mbleigh Of course you always need clear goals and strategy, but design docs are not about those, they are more about defining the implementation of a particular solution?

[Sébastien Cevey @theefer]

@steren @tsaha As long as you're not in a hurry…

Betting on @timzaman though 😅
