    It depends what they want to do. They can fork and take on the burden of maintaining the whole tree in which case good luck with that, linux is too much of a fire hose to enable a 3rd party to assemble something similar making different choices about what they merge. Otherwise they can maintain a re-based fork that tracks the Torvalds tree and then congratulations you’ve just invented a feature tree that can do contribution with extra steps.




  • Absolutely - modern pirates are extracting the digital streams with the DRM removed. However they closely guard the methods of operation because once the exploits or compromised keys are known they can be revoked and they have to start cracking again. They likely have hardware with reverse engineered firmware which won’t honour key revocation but still needs to be kept upto date with recent-ish keys.

    For example the Blu-Ray encryption protocols are well enough known you can get things working if you have the volume keys. However getting hold of them is tricky and you have to be careful your Blu-Ray doesn’t read a disk that revokes the old keys.

    For streaming things are a little easier because if you get the right side of the DRM you can simply copy the stream. However things like HDCP and moving DRM into secure enclaves are trying to ensure that the decryption process cannot be watched from the outside. I’m sure their are compromised HDCP devices but again once their keys get leaked they will no longer be able to accept a digital stream of data (or may negotiate down to a sub-HD rate).




  • They are pretty focused on reducing the cost of launches by aggressively re-using components that would normally crash into the sea. Previous launches landed on floating sea platforms but yesterday’s heavy was so big it needed a more stable landing zone. So after boosting the Star Liner the rocket returned down the trajectory it had followed up and then hovered briefly before being caught by two pincers on the very launch pad it had left five minutes before. That’s pretty cool.





  • What do people expect? Those servers aren’t free to run and they’re is only so much VC money to burn. That said I wouldn’t pay the various subscription levels that are currently being asked for. I pay for API use which is basically pay as you go. It also makes you think “does this task really need the non-free tier to complete?”.







  • QEMU is always going to focus on emulation fidelity first and there are few shortcuts. With floating point the differences aren’t generally in the numbers but in how the NaNs and other edge cases are handled. If you want to execute FP heavy code you should be cross compiling anyway.
