  • I was raised catholic and went to a catholic primary school. At one point we had a class where we would visit the local catholic church once a week and the priest would explain things about how things worked in church.

    On one such occasion he pointed out a red light near the altar and said that the light indicated that god was present in church. (Apparently it’s called a ‘sanctuary light’ in English). I spent an entire week trying to figure out how this god-detector worked. I had several designs worked out in my head, like it having an unreachable switch that could only be pressed by god himself.

    The next week we arrived at church a little early and I caught the priest putting a candle in it and lighting it himself. That’s when I started to realize the whole thing was one big scam.





  • It’s a bit of a PITA to be honest. Having to pre-heat the brew chamber is annoying and makes the whole process slow. They just released the Pro 3 which uses a different brew chamber that has a lower heat capacity and doesn’t need preheating (according to Flair). It’s compatible with the 2 so I’m probably going to get the pro 3 brew chamber once available.

    I’d skip the pro 2 and either get a 3 or the 58 with the electric heater.






  • Cycling through fresh snow is fine, it’s the snow that has been driven over and compacted that’s really slippery.

    When you ride over the slippery icy stuff, don’t brake hard, don’t make any sudden turns. Better to just stop pedaling and let your bike roll. Watch out for hard frozen ridges of snow.

    Usually the cycle paths are salted early, it’s the part from the busy cycle paths to your front door and the last bit to your destination where you have to watch out.

    Snow dampens sound so be careful around cars, you might not hear them coming. If you wear a coat with a hood it might be more difficult and annoying turn your head, resist urge to not look when crossing roads.





  • Lights using a 18650 seem to be the rage these days, at crazy cheap prices, but they all use some UI with clicks, holds, etc.

    I have an Olight Seeker Pro 4 and it’s pretty simple to use. The on/off button rotates and controls the intensity. You do have to either hold it for a few seconds to turn it on or rotate the button 90º and then click but that’s unavoidable with these kinds of flashlights.

    These lights are very small and yet very powerful. That means you can easily pocket them, but because they are so powerful they also get very hot. You don’t want a flashlight like this to accidentally turn on while in your pocket. If you look at these lights, the head is almost always ribbed, it’s basically a heatsink. Even then when you run them at full strength they usually throttle themselves down after a few minutes to prevent overheating.


  • They are also very different organizations with very different goals.

    NASA is focussed on science, they are trying to learn as much as possible about our solar system and the universe.

    SpaceX by contrast is focussed on engineering. They aren’t trying to find life on Mars, they are trying to build the ferry service to it.

    When NASA built rockets back in the 60’s, space flight was a science problem. We needed to figure out if it was even possible to do so. Can we even get a capsule into space? Can humans survive in zero gravity? Nowadays space flight is an engineering problem. We know it’s possible, we know the math, but can we actually build those things?



  • I’ve never been to a grocery store where the self checkout doesn’t weigh everything. That’s why people keep getting the “unexpected item in bagging area” error that requires an employee to come over to check and clear the error each time.

    Sounds like a stupid system.

    What stores in what country are you referring to?

    Pretty much every supermarket in the Netherlands.

    Here is a video of it in action

    The anti-theft equipment for a system like this that would prevent someone stealing by simply not scanning something is probably a lot more expensive than the usual self checkouts.

    There is no anti theft system other than randomized bag checks where they check up to 10 items from your bag to see if you scanned them. Takes about 1 minute and with daily supermarket visits this happens maybe once a month or so. (I think there is some kind of reputation system linked to your store loyalty card).

    Do you exit the store through a specific gate that scans stuff or what?

    You scan your receipt af the exit gate (you can also scan a barcode from the store’s app or choose a tiny receipt that only contains the exit barcode). You have to go through one or these gates regardless of wether you go through self checkout or not.

    If the store is busy I never try to self checkout since there are lines at all of them

    There are almost never lines at self checkout. There are 16 self checkout stations vs only one regular cashier. Self checkout is super fast and even if they are all occupied one usually frees up in less than a minute.
