  • For me, everything is a belief unless it satisfies the following criteria:

    1. It is generally accepted as true among experts
    2. There is ample evidence that is both personally convincing and leaves no room for alternate interpretations (not the same as #1, since many fields have “commonly accepted knowledge” that is generally acknowledged as most likely true but has no evidence to back it up)
    3. It is specific enough that it cannot be interpreted in a way that is misleading

    I find that the one that trips up most people is #3, since some people speak in technically true but overly broad statements and the listener ends up filling in the gaps with their own biases. The listener leaves feeling like their biases have been confirmed by data, not realizing that they have been misled.

    In the end, according to my criteria, very little can be categorized as true knowledge. But that’s fine. You can still make judgements from partial or biased data or personal beliefs. You just can’t be resolute about it and say that it’s true.



  • I mainly do work indoors, so the brightness does not really matter that much to me. But as far as I can tell, the brightness is pretty normal for laptops - I don’t think it’s any brighter or dimmer than other laptops I’ve used in the past. According to this website that I found, brightness is 25 to 486 nits. Google search seems to say that average maximum brightness for laptops is somewhere around 300-400 nits.

    My understanding is that the screen is generally what eats up most of the battery on device, so if you plan to have brightness turned up, it might be difficult to find a laptop with a long battery life.




  • Yes, but that’s my point, you see. Because Arm historically has been used for mobile and small devices, there’s been a strong incentive for decades to emphasize power efficiency. Because x86 historically has been used for desktops, there’s been a strong incentive to emphasize power. It’s only been very recently that Arm attempted to have comparable power, and even more recently that x86 attempted to have comparable power efficiency.

    Sure, Arm is currently more efficient, but the general consensus is that there’s no inherent reason for why Arm must be more efficient than x86. In other words, the only reason it is more efficient is just because they’ve been focusing on efficiency for longer.

    Both AMD and Intel’s current gen x86 cpu’s are, from what I can tell, basically spitting distance away from Qualcomm’s Arm cpu’s in terms of battery life, and rumor has it that both x86 companies should be able to match Arm chips in efficiency by next gen.

    So if efficiency is a priority for you, I think it’s worthwhile to wait and see what the cpu companies cook up in the next couple of years, especially as both AMD and Intel seem to be heavily focused on maximizing efficiency right now




  • Kubuntu on Framework 16 AMD 7000 series here. Sleep is horrible - definitely drains your battery. Bag heats up, and I estimate maybe a 1% drain per hour. I’ve enabled hibernate though I rarely use it.

    Battery is alright but not great. I get maybe 2-3 hours of active, light use from full battery.

    No compatibility issues that I’ve noticed, though, of course, Linux has its fair share of minor non-hardware-related bugs.

    Camera is serviceable but not amazing. Not sure about microphone but I assume the same thing. Speakers are somewhat odd in that the speakers are pointed to the side rather than toward the front, but again - serviceable.

    My upbringing was extremely “do what you want, but deal with the consequences.”

    “You can watch an R-rated horror movie, but don’t come to me if you can’t sleep at night”-type of situation.

    My impression has generally been that my freedom to do what I want let me learn a lot about decision making, responsibility, curiosity, and modern survival skills like Googling things. I’m genuinely baffled by how poorly some people my age use the computer and find things on Google, and I somewhat suspect many of them probably simply haven’t had the opportunity to explore technology on their own. And a lot of my hobbies were developed exactly because I allowed to do what I wanted when I was a child.

    As for children doing stupid shit and searching up things that aren’t appropriate for their age, my thought has generally been, why is it the parent’s role to keep that from the child? I strongly believe that a parent’s role is to prepare the child to be a functional adult, not to baby them.

    I acknowledge that all children are different, and perhaps there are some cases in which having parental controls would help. But I think my life would be duller if I were raised with parental controls.

    Edit: having read some of the other comments, I think there’s 2 aspects to the question of parental control. The first is the aspect of children learning about age-inappropriate things, which I’ve mainly been focusing on. The other is the aspect of discipline and management (ie, preventing your children from spending 12 hours on YouTube). I think people have made interesting points about this aspect, and I respect their opinions. I personally agree with BananaKing’s take that parental controls is the wrong tool for the job. Train your children properly and you shouldn’t need to use parental controls to control their screen time.





  • 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
