    Updating my computers from Ubuntu 22.04 to 24.04 was a whole day process. It doesn’t help that the upgrade tool requires you to press enter every so often.

    (Yeah yeah I should try other distros. I’ll play with other distros when I’m not spending my time as pictured in the meme.)

    (To be clear this is on a couple computer I personally own. The ones the lab owns are on Ubuntu 20.04 if I’m lucky…)





  • I primarily use Signal because I like my chats end-to-end encrypted. iMessage is not that bad on that front.

    I avoid any Facebook-written code like the plague, including WhatsApp and Messenger. They literally have a track record of putting malware in their products. I don’t understand why Europeans aren’t bothered by this.






  • When it does happen, hackers will be able to decrypt any vulnerably encrypted messages they capture now. We need to switch to post-quantum encryption well before quantum computers that can break encryption actually are built, such that any data they do actually decrypt is old enough it’s worthless.

    But the real reason why Microsoft is doing this now is simply because the decision on which algorithms should be the first official standard for post-quantum encryption have just been finalized. Expect a lot of companies to be adding post-quantum encryption in the next couple years.






  • A vector space is when you can:

    • add two Things
    • multiply a Thing by any real number

    And get another Thing that’s the same Kind of Thing.

    By Thing I mean Vector and by Kind of Thing I mean element of the same Vector Space.

    Examples of vector spaces:

    • real numbers
    • complex numbers
    • sets of N numbers (what most people think of when they hear “vector”)
    • matrices
    • polynomials
    • functions
    • quantum states of a given system
    • quantities of apples sold, classified by type of apple

    Examples of Not Vector Spaces:

    • integers
    • negative numbers
    • nonzero numbers
    • unitary matrices
    • apples

    Yeah a few of these come with asterisks I’m happy to answer questions but don’t want to argue with pedants.
