  • 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






  • Yes, and people do do it. It’s just incredibly difficult to do it even for relatively simple programs, and the more complex the program is, the more exponentially hard the reverse engineering will be.

    The problem is not necessarily turning it into code, since many decompilers do it already for you nowadays. The issue is understanding what in the world the code is supposed to do. Normally, open source code would be commented and there would be documentation, so it’s easy to edit or build on the code. Decompiled code comes with no documentation or comments, and all the variable names are virtually illegible.

    It’s sometimes easier to build something new than to fix what’s broken, and this would be one of those cases where it’s true



  • Not gaslighting, and from what you seem to describe, doesn’t appear to be manipulative either. She just seems to be angry. Not to say that you can’t be both angry and manipulative, but I don’t see clear intent for her to try to guilt trip or gaslight you.

    Gaslighting would be if she lied and said that she sent you a message when in fact she didn’t. i.e., lying with the intent to make you question your judgment and perception

    Guilt tripping would be if she pressured you into giving her a gift as compensation for ignoring her message. i.e., taking advantage of someone’s feelings of guilt to get them to do something for you.

    I don’t see any lie, and I don’t see hee trying to extract anything out of you. Worst case interpretation, she’s being a bit petty. Best case interpretation, she’s scared of being alone outside.

    I noticed your final paragraph, and I would be cautious in general about saying that someone who’s trying to convince you that their anger is justified is automatically manipulative. That’s kind of just how anger works. People think that their anger is justified. Otherwise they wouldn’t be angry. Manipulation occurs when you start to feel like you are being used for their own motives.

    Either way, you should probably talk to her about it. It seems like she thinks the issue is more severe than you appear to think, and that is something that should be discussed with her



  • Not a paleontologist, but I think it’s a mix of both wrong information being spread back then and also new info being discovered.

    I’m pretty sure people knew that birds were dinosaurs for a while, but people just liked the idea that dinosaurs were monstrous lizards. Giant monsters just capture the imagination in a way that giant birds can’t.

    And then paleontologists started finding fossils that had imprints of feathers still on the body, and it became really hard to ignore that dinosaurs were a lot more bird-like than people would like to believe.

    My impression has generally been that once dinosaurs started to be viewed as bird-like, people started to see them as animals rather than as monsters, and that just kinda snowballed into dinosaurs becoming more and more bird-like


  • Linux is really a superfamily of loosely-related OS’s (called distributions). Arch and Debian are 2 of the more common ones. Arch in particular has a reputation of being really beginner un-friendly, particularly in that, to my understanding, you have to build the OS yourself.

    There’s also the caveat that many Linux distributions end up sharing/copying code from each other, so you end up with a kind of “OS lineage.” The most common distribution, Ubuntu, is copied from Debian. And then the most beginner-friendly distribution, Linux Mint, is copied from Ubuntu. Arch, to my knowledge, doesn’t copy code from elsewhere, so much of the advice given from users of other distributions won’t apply to Arch (hence the meme, “I use Arch btw”)

    Anyways, the real advice for a Linux beginner is to stick with a beginner-friendly distribution: either Ubuntu or Linux Mint or Pop!_OS. Most or all distributions have various “flavors,” which are basically like how the OS looks. I think the real difficulty is picking a flavor that you like. I personally like the look of KDE Plasma (IMO resembles Windows 10 the most), so my personal recommendation is Kubuntu, which is the KDE Plasma flavor of Ubuntu

    Windows comes with a secret option to turn off updates with group policies, so you don’t need to modify anything or use a script. It works just fine for me. No updates (unless I manually click update).

    The option for automatic updates is several layers deep in a nested menu tree, and I don’t fully recall what the path to get there is. But you should be able to find it online.






  • Isn’t that just a government job with extra steps? I thought the point of UBI is that it’s meant to be, you know, universal.

    As a side note, people have this tendency to think that government programs must be means-tested. That is, there must be a criteria that is met before someone is eligible for the program. Same with your assumption in the post - you assume that it must be better to add a stipulation. There seems to be this natural skepticism that if there is no criteria, people will take advantage of the program. I want to challenge that skepticism.

    Adding criteria for eligibility inherently means the government must establish a bureaucracy for checking that the criteria is met. This has two notable downsides that people tend to not consider. First, it causes an applicant to wait longer before they can hear back from the program. With existing programs, it sometimes takes months before someone hears back. This ends up discouraging anyone from applying, even if they meet all the criteria. After all, what’s the point of receiving aid in 3 months if you need the aid now?

    Second, it causes the cost of the program to increase. A bureaucracy is difficult to maintain. The more money that is spent on checking for eligibility, the less money that people in need will get. And what is the work that such a bureaucracy will do anyways? How does it benefit society to hire someone to say that people’s needs aren’t “real enough” to get government aid?

    Which leads me to a third, additional point - it’s morally questionable to require people to meet a certain criteria before they can receive aid. To put it in another way, why do you feel like you need to gatekeep other people’s needs? If a person says they’re struggling, why should anyone say that they’re not struggling enough?
