  • I use to work retail selling (mostly) women clothes. At one point we had the same model of sundress with and without pockets. Every one of them that was watching or trying the one without got like super hyped and excited when we told them we had it with pockets. The pocketless one still sold better. And it wasn’t even a tight fitting dress, it was slack and baggy.




  • ‘Electric bus’ usually means a bus that relays in batteries to supply electricity to the motor(s). When, instead, it uses trolly poles (plural, it needs two) it’s called ‘trolleybus’.

    The third one is weirder. It’s like a tram/trolley, but I don’t see any pole or pantograph to supply the energy. I’ve read about diesel ‘tram-trains’, essentially several trams or light rail vehicles linked together. Do you know something more about this last one?







  • You can have beer in a bigger format in Spain, and if you go to a place to drink beer you would order something from a ‘tercio’ (330ml bottle) to a ‘jarra’ (usually 500ml, some places have 1-1.5l mugs). The tiny beer glasses (caña, ~200ml) have another purposes, for example if the place serve good ‘tapas’, a complimentary small dish served with your drink, since they have the same size whatever you order you get more food with smaller beers; or if you aren’t staying at the place and just want, or need, a quick refreshment before going somewhere else.



  • Don’t know about the glue thing, the smds were put by a machine, but they would move like the one in the picture if you didn’t set the machine right. I can’t say for sure with that resolution but I think those white things are the shiny reflections on the pins/solder. I will look into these smd glues tho, that could come handy.

    And about the tape I have to say that my experience with wave soldering is not very vast, literally just one place, but they used painters tape, of the cheapest kind, and it worked just fine—no melting (it’s paper?), and no burning since the solder doesn’t get that hot (~200°C), the tape might stay a bit wet from the flux also idk.






  • It is not a matter of more or less aggressive, some materials dissolve more easily in one type of solvent than in others. You can try, dissolving a teaspoon of salt in water is much easier than in oil. Have you ever eaten chocolate or drunk water while chewing bubblegum? Here the opposite happens, the fats in the chocolate dissolve the bubblegum rubber and make it softer while water doesn’t, it just chills it which makes it firmer.

    Now plastic, rubber, or paints, finishings… can be many different things. IPA is safe to use on natural rubber while oils will make it swell and degrade, or even melt it. But most rubbers are synthetic, basically rubbery plastic. These plastics and other engineered materials can have all kind of different properties, while looking exactly the same. So the only thing you can do, other than research on that particular material and solvent, is trying it on a safer or hidden part of the thing.

    In my experience: oil isn’t good on most rubbers, IPA is ok. For metals (iron, steel, mechanical parts…), contrary to you I usually advise to clean them with oil/grease, alcohol is appropriate if you don’t want it to be oily, only in rust resistant metals. Consumer/industrial products paints and finishings are usually fine with both ipa and oil if applied swiftly and dried quickly– acetone, kerosene, toluene… will strip them away probably. For wood, almost everything will fuck it up.
