  • I was trying to add a column of numbers in LibreOffice Calc the other day, and I ran out of fingers. Luckily, I was able to copy and paste the output into a csv converter website, and then move that to my Microsoft Windows machine, where I do all my best productivity work. Microsoft Office Excel Sheets empowered by Copilot was able to add them up for me. (17 was the total, in case you wondered)


  • My dorm building in college had exit doors that were undersized for the fire codes. They fixed this by moving the exit/entrance door to one side of the hallway, and adding an emergency exit door on the other side. The emergency exit door had a single red sticker on the push bar that said “Emergency exit - Alarm will sound”, and it really would. It happened at least 75 times in the first month after everyone moving in.

    They fixed this by sending everyone 75 angry emails about it. The same thing happened the next year, and also every year since then. I heard (but could never confirm) that putting double doors for the entry/exit doors would have cost a total of $3,000 more, for the multiple exits.



  • Oh boy… So, they took off from a test facility adjacent to Plattsburgh International Airport. I don’t see it stated, but I give it 98% they landed where they took off. Plattsburgh has some of the lowest residential and commercial electricity costs in the country, so that $5 nets them about 110kWh of juice.

    They also reached a maximum altitude of 1,100 feet with a plane that weighs in excess of 25,000 pounds. Lifting 25,000 pounds up to 1,100 feet takes 37 million joules of added potential energy, or a bit above 10 kWh.

    The entire remaining 100kWh of energy budget is the equivalent of accelerating the 25,000 pound aircraft up to 252 meters/second at perfect efficiency in a vacuum. This flight was not going very high, and it was not going very fast.

    If the economics of their hybrid idea work out, it’ll be fantastic, but the attempt at marketing over transparency here doesn’t fill me with optimism.


  • If Apple made a phone that could move around and take pictures of things, and the user asked it to take a picture of the trees outside, and it went to the trees outside and took peeping Tom photos of their neighbor, does the fact that the user asked it to take a picture of some kind make them responsible for whatever irrational and vaguely related thing it does based on the way Apple made the phone?

    Should Toyota be held responsible if they make a car where turning the wheel left makes the car turn left 99.99% of the time, and the remaining 0.01% it locks the accelerator, and steers towards the nearest orphan? They put a sticker on the dashboard to warn that sometimes it does that, and you need to be alert to turn off the engine, just in case. They also sell a version with no windows and no driver’s seat.

    If a gun explodes in someone’s hands, and injures them, is the manufacturer responsible?



  • There are plenty of kinds of surprise that can be wonderful in the right context. Perhaps easiest is when someone tells you they want/would like something, you keep an eye out for opportunities, and surprise them when it comes around. (My wife wanted to see a comedian. I subscribed to their newsletter, and then got (refundable) tickets when they were performing near us, years later.) There can also be things that you are confident someone else will like, which they don’t know exist. (I bought a friend a battery operated pruner after seeing him struggle to keep up with bushes.) Or small things that someone likes (flowers, chocolate, breakfast in bed, depends a lot on what they are into).

    The guitar repair was the worst kind of surprise: something irreversible, which the surprisee clearly knew about, and has chosen not to do at every single opportunity - while the surpriser doesn’t know why they are choosing not to. That’s not respectful, which is the absolute minimum requirement for a surprise to work.





  • No one knows why some CEOs succeed so much, and others fail so hard. Rather than admit that they are guessing, executive suites and boards of directors both engage in mystical thinking, and then shed as much blame/yank as much credit as they can get away with. CEOs are where they are because of a social club, and not because they have any specific demonstrable skills, high intelligence, overwhelming empathy, insight into the future of business, unmatched creativity, etc.

    Hallucinating that CEOs know what they should be doing, and the “more hours worked means more things got done” thinking are the largest and most damaging mental viruses of the corporate world.



  • It depends. It looks like the orange portal is being moved by a hydraulic cylinder (aka laminar flow), which means the relative positions and velocities of things moving through the orange portal are conserved, and A is correct.

    If instead that’s (yuck) an air fired cylinder… Then it’s going to be B.

    If the movement is handled by a threaded rod, then the box will emerge from the blue portal spinning, and (perhaps contrary to expectations) if the orange portal is moving because of gravity, then the bouyant force of the box progressing through the portal will stop it from falling further, and the box will end up just less than halfway (because of the angle) through the blue portal.





  • Disclaimer: I have only seen the trailers. Multiple things were from substantially incorrect regions or time periods. They could have at least tried.

    Also, I bought a Nolan movie to watch at home once, and the sound balancing was complete garbage. It was disappointing that he let his pretentiousness make his movie unwatchable. Maybe someday he’ll understand what art is for.

    Unless the people in my life that watch more movies than I do say it’s really good, I won’t see it, but also won’t be reviewing it for Rotten Tomatoes.
