    Yeah, I think the argument is that you shouldn’t need the cars to get people where they need to go. This can be addressed two ways: either we don’t use cars or we don’t need to go (as far).

    People should be able to travel with other modes that require less salt to deice, and cities could be built to not require cars for most trips. Salting sidewalks and bus lanes is better than salting those things plus roads and highways.

    It’s also worth considering that yes, people should be able to just stay home. People shouldn’t be at risk of losing their job/home because they couldn’t safely make it into work. Parents shouldn’t have to rely on school as daycare.

    I’d be curious to see if urban heat Island affects salt use. Maybe if we build dense enough, we don’t even really need salt to cover 99% of the population.





  • 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.


  • 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.




  • Sampson Boat Co. - British man and friends rebuild wooden sailing boat. If you have any interest in boats or craftsmanship you’ll enjoy. Watch from the very beginning to see their incredible progress.

    Beau Miles - Charming and slightly rough Australian man has strange adventures and philosophizes along the way. He gets excited about particularly useful/edible bits of trash along the highway.

    Primitive Technology - Silent man with blue shorts exists alone in the jungle and has been working his way up to iron tools. He is freakishly fast at making fire with only two sticks. Watch in order to see his progression and turn on captions to see his commentary.

    Spirit Of The Law - Extremely thorough Age of Empires II science and analysis. If you thought this 24 year old video game was dead, think again.

    Settled - Old School RuneScape player plays the game with extra restrictions that create surprisingly compelling storytelling. “Swampletics”, his Morytania-locked Ultimate Iron Man is legendary.

    DIY Perks - British guy makes mostly brass/wooden PCs and other tech. His creations aren’t always the most practical but they are always interesting. His slim PlayStation 5 was neat.

    There’s a handful of sustainable farming channels that I like: No-Till Growers, Richard Perkins, and Josh Sattin Farming. If your interests include food or growing stuff then these are for you.
