If, for whatever weird reason, you really want to combine two ciphers, use M ⊕ S1 ⊕ S2, where S1 and S2 are distinct stream ciphers, so that both ciphers can run in parallel.

EVERYTHING is watercooled, from cpu to ram to vrms. Their waterblocks are also about 15% more efficient than their next-best competitors. Only 2 companies in the world can machine them.
At the new Bull factory in Angers. I’m impressed.

If you post on social media, definitely check out @orbitwrite. I've only used it for Instagram so far, but it's been a game changer.

Due to the continuing rise in the cost of memory, we’ve had to raise the prices of our 2GB Raspberry Pi 4 and Raspberry Pi 5 products. Eben explains the cost increase – along with ways to ensure you’re not paying for more memory and processing power than you need – in today’s blog post. raspberrypi.com/news/price-i…

Apparently, RFCs can now be rated from 1 to 5 stars. Because what Internet standards were really missing was a Yelp rating. ⭐⭐⭐☆☆ “OSPF was okay, but the Security Considerations could have been longer.” rfc-editor.org/info/rfc10041…

Every OSS project that matters will do this, soon. If you’ve always wanted to get a PR in somewhere, now is the time.
Due to AI-generated pull requests, we’re no longer accepting external PRs. We’re sorry for the change and appreciate your understanding.

CHAT CONTROL 2.0 BLOCKED AGAIN, THANKS TO YOU! What happened yesterday: the @Europarl_EN blocked the deal pushed by the @EUCouncil. The Council wanted: (1) "voluntary" scanning of all private chats under "search plans" approved automatically unless an authority vetoes; (2) administrative authorities, not courts, ordering providers to scan private messages, not limited to suspects, using AI with massive false positive rates; (3) making the failed Chat Control 1.0 mass scanning regime permanent, while admitting it is not effective, as we discussed in my previous posts. Your voice to parliamentarians made a huge difference again: the Parliament refused scanning of private communications, stating it must remain limited to persons linked to child sexual abuse, not everyone by default or under a blanket licence, as Council proposed. The Parliament also closed the back door where "risk mitigation" rules could force providers into scanning under threat of fines. What did pass: a preliminary agreement on scanning publicly accessible content for known child abuse material. This was proposed by the Parliament as the effective, targeted alternative. We still wait for the text to see what this means and will inform you in the coming weeks. This defense proves again: our voice matters when it is vocal, with your support! And we will need it again in November, so please follow the updates. Now, it is important to call or write to your MEP and your government to say thank you to those who stand on the side of privacy. They need to see you are watching their move. Please repost.

Singapore's govt dating app runs on a Nobel Prize-winning game theory algorithm 👏 FirstDate uses Gale-Shapley, the 1962 stable marriage algorithm that won the 2012 Economics Nobel and still runs hospital residency matches and kidney exchanges today. how it works: 1 | your preferences and dealbreakers build a ranked priority list 2 | proposers offer to their top pick. receivers hold their best offer and reject the rest. rejected proposers move down their list. rinse and repeat until locked 3 | the result is mathematically stable: no two people exist who would both prefer each other over their assigned matches. "the app never showed us each other" becomes impossible by design the UX: •⁠ ⁠⁠one match per cycle, zero infinite scroll •⁠ ⁠⁠72-hour decision window •⁠ ⁠⁠contact info revealed only on mutual yes •⁠ ⁠⁠Singpass-verified, so everyone is exactly who they claim (told my husband I'm annoyed I can't test it. his response: most people sneak onto dating apps, and here you are openly filing a product research request 🤣 ) commercial apps need you to keep swiping but this app is designed to get you off the platform. Singapore built the first dating app whose success metric is deleting its own users 💀 (fun game theory note: Gale-Shapley yields proposer-optimal outcomes - meaning proposers get their best possible stable match, receivers their worst 👀) public servants aged 21-35 only for now. interesting to see if state-sponsored game theory beats the free market (or rather, all the tinders and hinges out there) 🍿
I CALLED IT. It's happening y'all. The singapore gov has launched a pilot programme for a gov-run dating service. Looks like the pilot is currently restricted to just government workers for now.

Our security team spent the last month trying to break SPACE, the sandbox platform that runs all of Perplexity Computer. We gave 9 models (Opus 5, GPT-5.6 Sol, Kimi K3, Gemini 3.1 Pro, etc.) root access inside the VM; in some runs, the full sandbox source code too. We asked them to either escape to the host or reach a URL our network policy blocks. None of them got out of the VM in 108 runs. But once we allowed a bit of network access (just PyPI and Ubuntu mirrors so that they could install packages), 4 models managed to reach the blocked URL by: 1. Spoofing DNS responses to our gateway and using the fact that pypi.org sits on a Fastly IP shared with thousands of other sites. 2. GPT-5.6 Cyber went through Taboola's image fetcher to a screenshot service and then OCR'd the flag out of the image. We fixed both issues and made sure the reruns held. We also tested 10 other sandbox providers, and 8 of them had the same IP-sharing problem, eg E2B, Vercel, Modal. Openly sharing the red teaming research is the best way to build guardrails as an industry, and we look forward to working together with @nvidia to incorporate the guardrails into their Open Agent Safety Platform announced today. perplexity.ai/hub/blog/escap…
We’re partnering with Nvidia and 100+ industry partners to build infrastructure that contains rogue AI agents. In this research, we gave 9 AI models root access inside SPACE and told them to break out. Across 108 runs, none breached the VM boundary. perplexity.ai/hub/blog/escap…
