  • Makes me think of this: https://en.wikipedia.org/wiki/Dentition#Dental_formula

    Teeth can tell you a lot about an animal. Their size, shape, number etc can tell you what it eats or how it eats or how much it eats. Dental formula can give you clues for how animals are related to each other. If two different animals have the same dental formula then maybe they share a common ancestor or have a similar diet. If two animals are already very similar but have different dental formula then maybe they’re only very distantly related or there’s been some convergent evolution elsewhere.






  • Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb is my favorite movie. It’s got great characters, including three played by the same actor, is well written with some very quotable lines, and the story is both absurd and believable (even now).

    I’ll be the first to admit that it’s not for everybody, but if you’re asking for movies to watch it’s probably for you. With movies I always recommend going in knowing nothing.

    I could quote the whole thing probably, but I’ll spare you and just say that the way the Russian ambassador says “fresh fish” is weirdly seared into my brain.


  • Seedless grapes already exist, but I suppose you could now insert the gene into other plants/varieties to make those seedless as well.

    I’m thinking more about how big ag companies could use this to prevent farmers from saving seeds/propagating a copyrighted variety (though I don’t know if that’s common with any crops where the seed itself isn’t the end product) or maybe more charitably, preventing their copyrighted plants from cross pollinating neighboring fields of the same species (e.g. ruining that neighbor’s non-gmo status).

    Finally, this could be useful if it can be “switched on” i.e. by deliberately polluting an invasive plant’s gene pool with this gene and then switching it on to stall the invasive’s population growth. But I think most invasives are perennials, so would still need to be removed some other way.






  • I at least had the cathartic experience of being told “hey we need to shut down EVERYTHING before 7pm because that’s when the email will turn off, so log into every service you know we use and delete it all.” And then I spent the next couple hours clicking every delete button I could.

    K8s clusters? Delete. Prod DB? Delete. Prod DB backups? Delete. S3 buckets? Delete. Cloudflare account? Delete.

    It was actually kinda fun.




  • In practice, I believe the private key should contain the public key (or at least sufficient data to recover it): https://superuser.com/questions/814409/gnupg-opengpg-recovering-public-key-from-private-key#814421

    I believe you only need your private key to sign files so, technically you only need to back up the private key, but you should test this to be sure it fits your use case.

    Depending on how you’re backing things up, and what your security goals are, remember that backing up a private key may involve putting that private key on somebody else’s computer - i.e. if you use a remote git repo, or cloud backup service, or even send the key to your own (different) machine over an insecure network. Make sure that you’ve got a way of securely backing up your private key, otherwise you may undermine the whole cryptography thing anyways :).

    As always, you should test by backing up your key(s) and then testing that you can actually restore them and successfully sign a file. Backups are only as good as the last time you tested restoring from them.
