- Comment on US military gives Lockheed Martin $33.7 million to develop nuclear spacecraft 1 year ago:
A working nuclear thermal propulsion (NTP) engine was already built in the 60s under NASA’s NERVA project. It is one of the highest technological readiness level solutions we have to the dilemma of high specific impulse versus high thrust present in the current spsce engine technologies. Imo we need something like this to make manned interplanetary missions viable.
- Comment on Plex will be blocking access from at least VPS provider 1 year ago:
Fair, although you’re probably fine for “hosting jellyfin for your family” levels even then. If cloudflare boots you, swap to a free tier Oracle Cloud VPS and set up an nginx proxy.

They removed that clause. Ctrl-f “video” on their ToS page gives 0 results

Example: grapheneos.org/faq#baseband-isolation
Yes, the baseband is isolated on all of the officially supported devices. Memory access is partitioned by the IOMMU and limited to internal memory and memory shared by the driver implementations…Earlier generation devices we used to support prior to Pixels had Wi-Fi + Bluetooth implemented on a separate SoC. This was not properly contained by the stock OS and we put substantial work into addressing that problem.
Baseband modems were not isolated from kernel memory in stock Android, GrapheneOS had to do it themselves using the IOMMU. We do not know for sure due to the proprietary/closed-source nature of baseband modem drivers, but we have no reason to assume any OEM (Samsung, Xiaomi etc) implemented proper isolation of baseband modem and system memory.
