Great marketing from Anthropic
Transparency & honesty always wins when marketing to engineers.

[Aakash Gupta @aakashgupta]

Anthropic shipped a launch chart where a competitor's number is bolded and theirs isn't.

Look at the terminal coding row. GPT-5.5 sits at 78.2%, bolded, beating Opus 4.8's 74.6%. On a slide Anthropic made, for a model Anthropic is selling, on the day they're trying to get you to switch.

Every other lab scrubs the losing row. You only ever see the benchmarks where they win, on the eval harness they tuned for. Anthropic left a loss on the board and bolded the winner.

Read the launch copy and it clicks. The headline feature isn't a benchmark at all. It's "more honesty about its own progress." A model that overstates what it accomplished is the single most expensive failure mode in agentic work, because you stop checking it. You hand off a bug sweep, it reports done, and the bug ships.

So the chart is the product demo. The thing they're actually selling is a system you can trust to tell you when it lost. The 74.6% that someone else beat is worth more to that pitch than a fabricated 80% would be.

Same price as 4.7, by the way. The honesty is free. The cost of not having it shows up three weeks later in production.

Scaling observability from a single Nagios box to thousands of VMs requires more than just swapping tools. Here is what we learned building it from scratch three times and the migration patterns that made it smooth. ⚡ 👉 https://t.co/o1dxpxtbmK

Proud of the team who responded to this vulnerability in the most diligent way updating all regions in an afternoon

[Upsun (formerly Platform.sh) @upsundotcom]

Over the weekend, we responded to the critical "DirtyFrag" Linux vulnerability (CVE-2026-43284 and CVE-2026-43500) by deploying an emergency kernel patch across all regions.

While our systems are not affected by the RxRPC vulnerability (CVE-2026-43500) as we don't compile that kernel module, we were affected by the IPsec ESP vulnerability (CVE-2026-43284) and needed to apply patches immediately.

To protect your data and minimize exploitation risk during the rollout, we temporarily restricted SSH and deployment access and performed brief service restarts.

While this vulnerability "only" provided root access within affected systems, we recognize that such exploits are typically used as the first step in a chain of attacks, potentially leading to container escapes and broader infrastructure compromise. Given this risk, we chose to err on the side of caution by implementing temporary access restrictions during our update window.

We understand this disruption was inconvenient, and the decision to disable SSH access was not made lightly. However, we believe these swift and decisive actions were essential to safeguarding your systems and data. Our priority is always to maintain the security and integrity of your infrastructure.

All services have now been fully restored, and you can access your projects and deployments as normal. If you're still experiencing any issues, please don't hesitate to contact our support team. We appreciate your patience and understanding as we work to keep your hosting environment secure.

Exciting!!

[Paco Villetard @pacovilletard]

We're coming out of stealth to announce our cyber defense research lab.

We are exploring data and post-training techniques to build superhuman cyber defenders.

Our mission is to make sure the West always wins.

The last 3 months we've built an automated data pipeline to create training data from 80k CVEs (aka public vulnerabilities).

Our next topic? Post training a model that's better at fixing all the vulnerabilities in your codebase.
Like really fixing them.
Not saying it's secure when there are still ways to exploit them.

Here are the questions that keep us awake at night:

How do you train a model to defend without improving its capabilities to attack? What's the right reward? How to measure the defense capabilities? How do you create synth training data that reproduces real systems? What kind of access do you give an ai cyber defender? How far can you trust it?

If you know insanely good cyber experts (red team, blue team, CTF aficionados) or ML engineers (synth data generation and post-training models), send them my way.

We need to make models far better at defending.

@brivael Intéressant et probablement juste à terme, mais pas en ce moment. En Q1, ce sont Anthropic et OpenAI qui captent toute la valeur software aux US. La somme des new ARR des boîtes de software publiques US représente 58$Bn d’ARR en Q1. Anthropic, à elle toute seule fait $21Bn ! 🤯

Sad! His Tour de France was magnificent

[Alpecin - Premier Tech @AlpecinPT]

We regret to announce that @mathieuvdpoel is forced to abandon the @LeTour prematurely.

Mathieu had been experiencing symptoms of a common cold over the past few days. Yesterday afternoon, his condition began to worsen significantly. The team doctor monitored him closely throughout the day. By the evening, Mathieu developed a fever and was taken to the ‘Centre Hospitalier de Narbonne’ for further examinations.

Medical tests revealed that Mathieu is suffering from pneumonia. In consultation with the medical staff, it was decided that he can no longer continue the race. His health is the top priority, and rest and recovery are now essential.

Mathieu will be required to rest for at least one full week. After this period, he will undergo further medical examinations to assess his recovery and determine the next steps in his rehabilitation.
