I am hiring a Chief Information Security Officer.

See https://t.co/7p3Gj9PN4m for details.

DM me for questions.

This is an exceptionally cool job in an exceptionally cool market (large-scale battery systems), with moats that make those of most SW/HW startups and scaleups pale by comparison.

Note to recruiters: do not contact us in any shape or form about this role. A company-wide ban on your email domain follows if you still do.

Once you see it as a salary then costs are actually low

[Taylor Otwell @taylorotwell]

If my personal AI subscription was like $4,000 a month I would be like “yeah makes sense I guess” and just keep paying it… honestly incredible what we get for $200 / month

@BryanOnel86 Plus these screenshots must often contain your name in the menubar/taskbar 😅 and show the date/time as well. Bizar

@tommithetechie We featured the 1541 prominently in https://t.co/Js1LC1S07m (1986!)

Been running Opus 5.5 agents over the notebooks of Gauss, Riemann, Hilbert and Grothendieck. around 12,000 pages so far. Heres the best finding so far:

Riemann's 1860 shock wave paper is famous for getting the energy part wrong however his unpublished sheets at Göttingen have it right the Rankine Hugoniot conditions a decade or two before Rankine and Hugoniot plus results usually dated 19061937, all in his own notation. A second sheet in another folder has the same physics.

There are probably thousands of potential undiscovered stuff in the research papers of the smartest ever to live imo all of them should be made public and reviewed by ai years of work can probably be transcribed by agents in days

@mnwsth Yeah right 😅

1. Understand the "11:00 PM Freedom Window"
All day long, an ADHD adult spends their energy answering to bosses, schedules, chores, and household demands.
At 10:30 PM when the house finally goes quiet, it is the very first minute all day that nobody expects anything from them—so going straight to sleep feels like fast-forwarding straight to tomorrow's work alarm without getting a single minute of personal life. 2/6

@ladyxtel Thank you! Will be watching your endeavors too 🚀

Very proud to announce that https://t.co/XCDGsSNhpV has secured €835 million in portfolio financing, underwritten by Deutsche Bank and Rabobank. We'll use the money to build a fleet of large-scale batteries in Germany, which will act as one virtual battery.

[Erik van Eykelen @hackteck]

@drhingram I can scientifically attest to the fact that they do

[Erik van Eykelen @hackteck]

@ashiqdey Full stack: seldom, it's backend mostly (Go, Python, Ruby). + candidates must be based in Europe for regulatory reasons. Positions will be announced on https://t.co/uDzaMokTCL

@damnang2 By doing it this way Elon and his engineering team now understand the problem much better than before. That is the power of removing dumb requirements (or not dumb, as in this case)

[Erik van Eykelen @hackteck]

@jacobandreou Indeed, not going to believe

[Erik van Eykelen @hackteck]

Great foundation for a company-specific hardended OS 🤔💡

Omarchy 4.5 is finally here! Traditional desktop mode, M1/M2/M3/Neo compatibility, 50 languages, 7-second installs, and a million other features, fixes, and improvements. https://t.co/lYxY1zFxAM

A hop-by-hop view of @Cloudflare network engineer @tstrickx crossing the Atlantic on Starlink Wi-Fi.

Over 8 hours and 7,000 km, Starlink handed off satellites every 15 seconds and carried traffic through 7 Cloudflare deployments. Each plane appears to keep its own IPv6 /56.

Over the ocean, inter-satellite lasers carried traffic to the nearest available ground station. Cloudflare’s anycast routing followed it, keeping traffic local as the plane moved at 40,000 feet and 500 knots.

- Ocean crossings use inter-satellite laser links until traffic can reach a ground station.
- Those laser routes appeared slower than fiber in this single test.
- Latency showed two distinct bands, possibly from first-packet dataplane setup.
- Ground-station selection changed during the flight, including a Canada-to-US switch near the border.
- Cloudflare’s anycast routing followed the ground station, not the plane’s source address. That kept traffic local without DNS-based steering.
