  • There is around a century’s with of uranium with current mines.

    But right now uranium is very cheap so most of it is “wasted”. There is plenty of way of recycling used nuclear fuel or improving the productivity of uranium enrichment.

    If uranium supply starts to actually be a problem there is a way to “create” more nuclear fuel: breeder reactor.

    With breeder reactor France could fuel their reactor for millennia only with the depleted uranium they have in stock (when enriching uranium you end up with a tiny account of enriched uranium on one side and depleted uranium on the other, France is keeping the depleted uranium in stock specifically for this scenario)

  • SpaceX exists only because of NASA.

    The Merlin engine is based on an engine developed by NASA, they even started by buying the exact same turbopumps directly from NASA’s subcontractor

    The initial funding from Musk ($100 million) allowed SpaceX to develop the Falcon 1, in 2008 they only reached orbit on its 4th attempt. At this point they had no money left, a small rocket with a terrible track record and no customers for it.

    3 months later NASA awarded a $1.6 billion contract to SpaceX for the ISS resupply ! This is what allowed then to continue and develop the Falcon 9.


  • From another article

    The GDM724x is removed for supporting the GCT GDM724x LTE chip based USB modem devices. This driver was merged back in 2013 but is being removed now as the driver isn’t being maintained and yields a maintenance workload, the manufacturer GCT doesn’t respond to any emails/support, there doesn’t appear to be any of the said chips easily available for purchase, there is not any hardware documentation available, and no apparent usage of this driver remaining in the Linux community. Removing the driver clears out 3.6k lines of code and lowers the maintenance burden for other kernel developers.

    There was also a vulnerability discovered in July linked to this driver.

    So yeah I understand that they chose to remove some drivers from the kernel.
