  • According to the FAQ (warning: very wordy):

    The goal of the project is not to slightly improve some aspects of insecure devices and supporting a broad set of devices would be directly counter to the values of the project.

    The expectation is for people to buy a secure device meeting our requirements to run GrapheneOS. Broad device support would imply mainly supporting very badly secured devices unable to support our features. It would also take a substantial amount of resources away from our work on privacy and security, especially since a lot of it is closely tied to the hardware such as the USB-C port control and fixing or working around memory corruption bugs uncovered by our features.




  • I meant basic memorization, not any advanced stuff. If you have to re-derive everything basic from scratch again and again, you will be less effective at advanced stuff.

    This is not to say the basic stuff should just be memorized. Rather, it should first be understood and only then be memorized.

    And definitions must be memorized, otherwise you’re screwed. For instance, try proving something is a group if you forgot the definition of a group. Yes, the definitions have reason for being the way they are (which you will likely learn) but definitions just cannot be derived from your mind during an exam.

    In OP’s example with memorizing multiplication tables instead of doing them on-the-fly: This is a core skill required for so much later on. You don’t want to waste time and energy thinking about how e.g. 7•8 = 7•2•4 = 14•4 = 14•2•2 = 28•2 = 56 because that’s a quick way to lose focus. Especially if you – like me btw – have to invert a 7x7 matrix with two variables x,y put in a bunch of positions (and linear combinations of them) in an exam.

    Edit: substitute unescaped *s with •


  • Strongly disagree that memorization isn’t important. It’s THE foundation to be able to do effectively do more advanced stuff.

    Take the equation (5678 • 9876). Use long multiplication and you only rely on doing a bunch of single digit multiplications and additions. It’s so much faster to be able to instantly know each step instead of having to recalculate these “atomic” steps again and again in your head.

    You generally don’t need to be able to solve multiplications involving double digits in your head. It’s nice-to-have but otherwise useless, as long as you’re able to calculate the ballpark of the result.

    For example, (38•63) is roughly 2400 and I can then calculate it on paper instead of in my head.

    Head calculations are just so much more error-prone than written calculations. Don’t do them if you can avoid them. There’s a reason why math students (at a university) are infamous for being unable to make the simplest calculations in their head. It takes effort that could be spent somewhere else.


  • I think it can apply to the most general workflow with branches as well, where branches are used to develop features and then later merge them.

    After all, any new branch is basically a “remaster” until merged back in, which is when the original master becomes the remaster.

    Sure, the analogy isn’t perfect because in music the original master isn’t supposed to change – but the entire purpose of a version control system is to change the “master record”, i.e. what’s deployed to production.
