    Yeah, but they require somewhere in the neighborhood of a thousand pounds of batteries to do so. Some of the more egregious ones need multiple thousands, e.g. the electric hummer whose battery alone is heavier than an ICE Honda Civic. Whereas a dozen gallons of gasoline (roughly 72lbs at 6lb/gal) can power that same ICE Civic for a nearly equivalent range, while causing much less wear & tear on the roads, and likely releasing less tire particulates due to the reduced weight. Of course it still releases CO2 and other nasties…

    But yeah, the energy density of EVs is still super bad. It’s just “good enough” that we’re making it work.

    As I understand it, the big issue is energy density? A tank of gasoline takes you quite far compared to an equivalent tank of hydrogen.

    And don’t get me wrong, lithium batteries are super bad at this too, but I do think that has been a limiting factor for H cars.

    And then there’s the whole tire dust issue which is definitely a conversation worth having.




  • It was fine. A total of maybe 8 minutes of interesting content. I enjoyed the segment with Tawny Newsome and Eugene Cordero watching silly clips. And the interviews on the street were cute.

    Jerry O’Connell did have a slight “blink twice if you need help” vibe going on, but I’m not sure how much of that is me projecting it onto him given that the strikes are going on (but I assume this content was prepared in advance?). And honestly, I couldn’t do half as well “hosting” a show with no guests in front of a green screen!

    The segment about Discovery was a bit…

    And I’m actually a discovery fan! But wow that Paramount Plus narrator was so proud of their achievements, lol



  • People aren’t misunderstanding the issue. Third party cookie support is being dropped by all browsers. Chrome is also dropping them, but replacing them with topics. Sure, topics is less invasive than third party cookies, but it is still more invasive than the obvious user friendly approach of not having an invasive tracker built into your browser. No other major browser vendor is considering supporting topics. So they’re doing an objectively user unfriendly thing here. This is the shit that happens when the world’s largest internet advertising company also controls the browser.


  • A classic use for them is spam filtering.

    Suppose you have a set of spam detection systems/rules which are somewhat expensive to execute, eg a ML model or keyword blocklist. Spam tends to come in waves, and frequently it can be as simple as reposting the same message dozens of times.

    Once your systems determine a piece of content is spam (or you manually flag content), it’s a good idea to insert the content into a bloom filter. This means that future posts of the identical content will be flagged without needing to execute the expensive checks, especially if there’s a surge of content stressing your systems.

    Since it’s probabilistic, you can’t use this unless you have some sort of manual reviewing queue or system, as it’s possible for false positives to be flagged. However, you can also run more intensive checks once you’ve flagged content, to detect false positives.

    The false positives can also be a feature, not a bug: with careful choice of hash functions, your bloom filter can actually detect slightly modified content, since most of the hashes may still be the same.

    I’ve worked at companies which use this strategy so it’s very real world.







  • I know reviews are pretty mixed, but I enjoyed listening on and off as I watched Voyager! But I will say that their episodes were pretty long winded for my tastes. In particular, while I understand why they had a section describing all the guest actors, writer, and director, they spent a bit too much time on it for my taste. Especially the actors, where they covered each actor’s first role and usually had a bit of a IMDB review. I personally only really care for the stories about the production of each episode, and also their general reception/opinion of each episode is fun since they’re deeply a part of the trek world.

    For me, a briefer version would have been a home run. As is, it’s worth a listen, but you should feel free to skip around.
