    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).





  • I think it’s often used with younger kids because parents don’t understand why their kids are acting up and can’t work out how to “get through” to them. As kids get older they become a lot better at understanding and really words should be the only tool you need.

    The dreaded phrase “I’m not angry just disappointed” should cut deep when (rarely) used because the kids understand their parents have their interests at heart. If they don’t then something has gone wrong building that relationship of trust and respect.

    ETA: forgot to say of course positive reinforcement is also key. Kids need to know when they get things right so they are not walking on eggshells worried about getting things wrong.





  • 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.
