He mentioned in spots GCC 9.1 was used, albeit still missing parameters. This is odd to test considering how old it is and how the .1 release is not the last bugfix release for the 9 series. Edit: I see the 9.1 reference is itself referenci

There are a number of RTOS’s out there now, both proprietary (e.g. VxWorks) and OSS (Zephyr) that support A-series chips with an MMU, and can operate with a single (kernel) context. They still provide bounded latencies compared to full-fat

That philosophy extends to the kernel only - there are multiple other dependencies for running programs that may not have a stable API/ABI, or the same compatibility approach. Shared libraries like glibc may be updated, graphical inter

I’m going to bet the opposite - no school is so flush with cash they can pay a 3x premium per laptop for students thet offers the same functionality. This seems like a misguided approach to obtain mass market appeal.

How new is this project? It was really surprising to see something published in 2022 that still attempts to offer Python2 support, and all the baggage that will carry.

1. There’s extra danger every time nuclear material is launched on a satellite, be it for a thermal generator like on the Curiosity rover, or some failed tests the USA did on Pacific islands in the 60s as part of Operation Fishbowl that res

Purely analog circuits, including those with digital functions as an ancillary feature, are never on the latest process node. Analog functions don’t scale down well, high drive currents or voltage support require minimum feature sizes. The

Not anymore for all practical purposes, but it once did for the very old 10Base-2 standard for Ethernet over coaxial cable. This is practically why the old MII Ethernet PHY interface protocol had the collision-sense lines to indicate to the

Can you list which ARM cores you know of that include an IOMMU? I’m personally unaware of any, as that is typically bundled as a separate IP package that must be integrated separately into the system, and is usually customized based on the

No GPS sat's are in GEO - they're all in MEO, which is about half as high, though comparative in terms of dV requirement.

Two things: 1. A GPS satellite is in a very high orbit compared to LEO, and so all stages were requested to burn to completion, to ensure the satellite has enough margin to reach that orbit. 2. The second stage ends at a ~800 km orbit, whil

Those (Anandtech) benchmarks were performed on Windows. All threadripper benchmarks on Linux show that it is nowhere near as awful a performer as on Windows and most compute workloads do scale okay. Seen multiple ideas thrown around like Wi
