  • Science is like going down a Wikipedia rabbit hole. There’s always more things to do and more things to check out. At some point you just have to draw the line and say that enough is enough. Other scientists are likely to ask why you stopped where you stopped, and so saying that “it’s outside the scope of the paper” is basically the nice way of saying that you stopped because you felt like it







  • Because the ones that we hear about are the ones that are good enough to have even made it out of Japan. If a game was bad, it wouldn’t be localized to an English-speaking audience, and we wouldn’t even know it exists.

    It’s the same sort of thinking as asking why (insert media here) was better in the past. The answer is simple - good songs, games, movies, etc. tend to be more memorable, and so we remember the good ones and forget the bad ones. To put it briefly, there’s survivorship bias.




  • It seems to be a per-school kind of thing. I am late millennial/early Gen Z, and my school had computer classes where we learned how to use Windows and Microsoft office, how to touch type, the meaning of computer terminology, and what the functionalities are of basic computer parts (eg, “CPU is the brain of the computer”). And later on we started learning how to use Photoshop and Illustrator.

    I’m always surprised when I hear that other people don’t have that sort of in depth tech learning in their schools, and worse so, that some people don’t even have computer class. It just always felt like what we learned in computer class was an essential skill





  • You can’t outright, but you can at least try to minimize your exposure. Easiest way is to avoid buying products that use plastic packaging, especially if the product that you’re planning to buy is food. Don’t microwave plastics, even the supposedly “food safe” one - that releases a ton of microplastics into your food. Don’t order takeout - again, lots of plastic in the containers. Even paper food containers contain a plastic coating.

    Don’t touch receipts, especially with wet hands. Or at minimum, wash your hands thoroughly after touching it



  • I find that it’s best to use 65C for the bed temperature for the first couple of layers, and then drop the temperature to 50C. If you’re using Cura, there should be an option to do that, but you’ll need to dig through the advanced settings to find it. Doing this has completely solved warping for me (Ender 3 Pro v1 with PLA filament). My understanding is that it works because the temperature differential between the top and bottom layers causes a pulling force that causes the warping that you see. I think it’s something about the expansion of the plastic due to heat - as the plastic cools down, it shrinks, which pulls the layer below it upward. The wider the base, the stronger the pulling force. And the more layers you add, the more the pulling force compounds, until eventually the print warps.

    The solution is simple - minimize the temperature differential. You really only need it to be hot on the initial layer, for the print to stick properly. And afterward you only need to maintain a temp that’s just hot enough that the print doesn’t pop off. Hence, 65C initial, 50C for everything else afterward

    Probably less relevant, but I also find that adhesion improves if you have the printer go at half speed for the first couple of layers. Again, there should be a setting in Cura, but it’s in the advanced settings

    I find that I can just use these 2 modifications and everything just works. No need for glue. I just dust off the bed when it gets dusty but beyond that, I don’t mess with it. Actually, the adhesion is quite strong. Even after the bed has cooled to room temperature, I have to exert a bit of force to pull the print off the bed

    Scientists can get really petty in peer review. They won’t be able to catch if the data was manipulated or faked, but they’ll be able to catch everything else. Things such as inconclusive or unconvincing data, wrongful assumptions, missing data that would complement and further prove the conclusion, or even trivial things such as a sentence being unclear.

    It generally works as long as you can trust that the author isn’t dishonest
