GoTEE opportunistic soft lockstep is pushed and documented in the wiki. github.com/usbarmory/GoTEE/w… Tested to catch faults on bare metal Go and Rust Trusted Applets. The bulk of its implementation is 20 LOCs thanks to the GoTEE abstraction and TamaGo! github.com/usbarmory/GoTEE/b…

Any friends know of projects other than NetPi-IDE which is seemingly unfinished / abandoned?
I really want to make a device I can plug into an IDE host which will emulate a hard drive, pulling data over ethernet from an AoE server or the like. Trying really hard to resist taking on another project >.<

Sounds more like an issue with their training materials if their employees were able to attend two at once and pass whatever questionnaire / exam was associated with it.
These things are getting ridiculous.

This is an amazing achievement. Very excited for Starship’s future and what it will unlock and enable
Video from a different vantage point shows Starship Booster never came even close to hitting the tower. As far as I can tell, this was as perfect of a Mechazilla catch as SpaceX could have hoped for.

FlightAware has a page up tracking the UPS planes loaded with iPhones heading to the US for Friday’s launch. Assuming roughly 300,000 iPhones fit a 747-8F, just one group planes near Alaska was hauling $2,330,200,000 ($2.3 billion) worth of iPhones this morning.

I went on a 17 hour Search and Rescue op in the rain yesterday. 12 hours in, the team was complaining about being "gassed" discussing giving up and I was just like 🤷🏼‍♂️ I'm at like 95% and I've been up since 0230. Could not relate at all. Couple thoughts here... 🧵

It certainly resembles a Clancy plotline in that it is well within the technical and logistical capabilities of many world powers and is compelling enough to make for a good read.

This is the wild story of how I made $1,036,175 during the COVID lockdowns by rapidly creating a new physical product in 7 days. In April 2020, during the lockdowns I created 2 things that changed my life: 1. – I launched Shepherd (eventually renamed Somewhere[dot]com). 4 years later we sold it for $52,000,000. 2. – I created a new physical product that made us $1,036,175 in 60 days. This is the untold story of #2.

These new RP235x chips are a Cortex-M33 / RISCV fever dream. Will be really interesting to see how folks mix and match the cores in actual usage...
Raspberry Pi has two new chips out – RP2350A and RP2350B. Some quick stats: - 2 x ARM M33 cores at 133MHz - 2 x RISCV Hazard 3 cores (up to 2 cores at once, mix and match) - 512K RAM (vs 264K on RP2040) - 3 PIO modules (vs 2 on RP2040) - Hardware floating point unit

Starlink Mini teardown and quick overview. Compactness and integration have their price. Terminal with the lowest repairability rating. All new Catapult SoC with built-in secure core. Single chip 8 Gb RAM. 2 digital beamformers. GNSS receiver with external LNA and patch antenna.

This is what I want to see AI used for, not to create yet another social media auto replier for marketing.
