@business Drones detection systems are working now, that's good news 🤩

@Polymarket Happy and ashamed at the same time that a non European investment bank had to do what nobody in eu was willing to do

@elonmusk @ID_AA_Carmack now they need you to get even closer to bare metal 🤩

@Polymarket "clients are questioning the value" 🤣🤣🤣

[Sergio Giucastro @StudioSG]

@Polymarket my next startup idea: resell the $2 million worth tokens with a 50% discount to other startups in exchange for equity, pay to myself a $1 million salary

Self-hosted sandboxes and MCP tunnels are great news for corporates

[Claude @claudeai]

Live from Code with Claude London: we're launching self-hosted sandboxes (public beta) and MCP tunnels (research preview) in Claude Managed Agents.
Run agents inside your own perimeter, with your security controls applied by default.

Maybe OpenAI too is using a similar approach? They just announced their ChatGPT for personal finance product 😅

How to use Grok to build the next startup, product or service: just ask Grok to Identify the top 5 problems people have been venting about on X (posts + high-engagement comments) in the last 6 months. This is what I got:

5. Real-life ADHD/executive dysfunction struggles (not the “fun” meme version) + daily decision fatigueHigh-engagement posts calling out how ADHD feels like “specific dementia ruining your life at every step,” plus overlapping complaints about outfit/packing decisions, forgetting maintenance/returns, one-sided friendships, and voice-note overload - Product/service opportunity: An adaptive ADHD “life co-pilot” app that uses context-aware AI for executive function (smart reminders that adapt to your energy, auto-generates packing/outfit lists from calendar + weather, transcribes/summarizes voice notes instantly, suggests low-effort social check-ins). Existing tools feel one-size-fits-all; this one would actually understand the brain wiring.

4. Hustle culture burnout and craving slow/peaceful living (time > titles, “I don’t want this life I worked for”) -Product/service opportunity: A “peace-first lifestyle OS” app that enforces digital boundaries, builds slow-morning routines, blocks hustle-porn content, tracks “peace score” instead of productivity porn, and connects users to like-minded slow-living communities/events. It would be the anti-Grindr for your nervous system.

Jailbreaking an F-35 🤔

[Clash Report @clashreport]

BIG: Dutch Defence Minister Gijs Tuinman hints that software independence is possible for F-35 jets.

He literally said you can “jailbreak” an F-35.

When asked if Europe can modify it without US approval:

“That’s not the point… we’ll see whether the Americans will show their true colors.”

And then he dropped this:

“I'm going to say something I should never say, but I'll do it anyway. Just like your iPhone, you can jailbreak an F-35. I won't say more about it.”
