  • a chewing gum made from lablab beans, Lablab purpureus—that naturally contain an antiviral trap protein (FRIL)—to neutralize two herpes simplex viruses (HSV-1 and HSV-2) and two influenza A strains (H1N1 and H3N2). The chewing gum formulation allowed for effective and consistent release of FRIL at sites of viral infection.

    They demonstrated that 40 milligrams of a two-gram bean gum tablet was adequate to reduce viral loads by more than 95%, a reduction similar to what they saw in their SARS-CoV-2 study.

  • This plus good other images are amazing, thank you!

    For me, in this one, the receding reeds capture the show... The way Japanese prints use negative space is unequalled, even in contemporary art!

    Photography was available during his time, and he seems to be mixing traditional with a much more modern look. It's fantastic:

  • Ok, so Two-Tone-Beard-Man is Marx, Slightly-Darker-Beard-Man is Engels, but who are Long-Beard-Man and Auntie-Glasses-Lady? I ask because Long-Beard-Man appears to be the winner of the heated exchange at the end...

  • "could help solve" was the quote.

    Physics is like that joke about halving the distance to a woman at a bar*. I don't expect it will ever be entirely solved, but whatever stands as the "for all practical purposes" of the era might. I'm taking "help solve" as just another halving of the distance in this analogy.

    A mathematician and an engineer are sitting at a table drinking when a very beautiful woman walks in and sits down at the bar.

    The mathematician sighs. "I'd like to talk to her, but first I have to cover half the distance between where we are and where she is, then half of the distance that remains, then half of that distance, and so on. The series is infinite. There'll always be some finite distance between us."

    The engineer gets up and starts walking. "Ah, well, I figure I can get close enough for all practical purposes."

    TL;DR

    If you're short on time, here's the key engineering story:

    • McIlroy's first innovation was a clever linguistics-based stemming algorithm that reduced the dictionary to just 25,000 words while improving accuracy.
    • For fast lookups, he initially used a Bloom filter—perhaps one of its first production uses. Interestingly, Dennis Ritchie provided the implementation. They tuned it to have such a low false positive rate that they could skip actual dictionary lookups.
    • When the dictionary grew to 30,000 words, the Bloom filter approach became impractical, leading to innovative hash compression techniques.
    • They computed that 27-bit hash codes would keep collision probability acceptably low, but needed compression.
    • McIlroy's solution was to store differences between sorted hash codes, after discovering these differences followed a geometric distribution.
    • Using Golomb's code, a compression scheme designed for geometric distributions, he achieved 13.60 bits per word—remarkably close to the theoretical minimum of 13.57 bits.
    • Finally, he partitioned the compressed data to speed up lookups, trading a small memory increase (final size ~14 bits per word) for significantly faster performance.
  • No, never did find it... But I'm pretty sure now that pen really was his. It was just a mildly unlikely coincidence that he had one just like mine.

    I felt at the time that I'd been conned out of some things in the past, and that had me set a bit too hard on "not being fooled again", so I overdid it.

    One particular case I remember is exchanging toy cars with someone, and them claiming later that day that they lost the car i just gave them. So I spent a good few minutes looking for it with them. I even insisted "no, let's look again" when they suggested we give up. I felt bad that they'd lost out on our exchange, so I gave them back the car they'd given me, just to ease their misfortune. Only to hear the next day how they'd been bragging about fooling me. Gah.

  • I had a similar thing with a pen, the very same year I think... I had a mildly special pen which one day I lost. Went looking for it and found it sitting on a (slightly older) classmate's desk, so i grabbed it and said "hey, that's mine". He tried to pretend that no, it was his, and he sounded very convincing about it, and even got the teacher involved. They both looked at me with infuriatingly condescending expressions as I explained how it was mine.

    The teacher suggested "just let him have it" to the classmate, who conceded.

    I went back to my desk fuming and scratched my initials into it before returning to show them, "look, see, it was mine! The classmate immediately pointed out "you scratched those in just now" and I think I mumbled something incoherent before going back to my desk, to the teacher's mortification with the whole situation.

    It had already begun dawning on me at this point that the classmate was right... That wasn't my pen. It was his and just looked like mine. But it was too late at this point and I didn't know how to handle it other than to keep quiet and try to forget about it.

    Tesla Cybertruck appears to be facing significant sales challenges. After initial hype faded, and over a million reservations turned out to be as real as unicorns, Tesla is now enabling leasing options and free upgrades to move its inventory of the futuristic pickup truck. The company's recent silence on the Cybertruck, even omitting it from their earnings call, speaks volumes about the situation.

    Tesla initially projected sales of 500,000 Cybertrucks annually and established production capacity at the Giga Texas for 250,000 units per year. After working through the initial reservation backlog with fewer than 40,000 deliveries, the automaker is now struggling to sell the remaining vehicles.

    What Russia wants from Ukraine is not territory, but submission (Anders Puck Nielsen)

    I thought this was a very insightful video. Anders is often able to discern stark simple truths and their implications without falling into the trap of common misconceptions.

    The prediction about what Russia will do on January 20th seems very likely to me.

    Anders was one of the very few analysts that predicted Russia was going to invade in the months/weeks before their actual invasion.

    What's the most significant thing you could do as an ant, if you kept your current mind?

    Imagine you were reborn as a female queen ant with an expected lifespan of about 15 years (worker ants live about half a queen's timespan), and had the ambition to make the most of your tiny new life. And you got to keep your current intellectual capacity and knowledge.

    How much could you achieve as an ant?

    The unpleasantness of mosquito bites is not something useful for mosquitoes, but it is useful for the ones who suffer it

    The way our bodies react to mosquito saliva motivates us to avoid being bitten. Which must have had evolutionary benefits, keeping us away from diseases.

    I.e. all those people that didn't mind them and never got itchy from mosquito bites appear to have died out. And mosquitoes really wish that wasn't true.
