  • Quick counter: lower kelvin lights are terrible for color reproduction. Pure sunlight is around 5000K, and has a CRI (color rendering index) of 100. Switching to warmer (lower kelvin) lights is going to also alter your CRI, and will change the way that you perceive colors. If you need high color discrimination, that’s going to be bad.

    For outdoor lights, in most cases that’s not a problem.

    Usually. In most cases, you aren’t going to notice just how much the colors have shifted, because your brain automatically adjusts. Youre perception of color is usually how colors appear relative to other things; you will see a red as red because your brain is comparing it to other objects with a known color. OTOH, if you’re taking photos under poor lighting conditions, you’ll see a significant shift in color. If you’ve ever taken film photos under fluorescent lights, you’d see that everything looked sharply green, when you don’t perceive them as being green at that moment. (Digital cameras often make color adjustments, and the sensors are often not as sensitive as film can be.)

    Going to an extreme, if you use a red filter on a light source, all colors are going to end up looking brown and grey; switching to red lights does the best at minimizing light pollution and loss of night vision, but at the cost of most color information. That’s not bad, just a thing to consider.




  • I used to be a member of the NRA too, but I’m not willing to pay for some dude’s $15,000 suits while he’s kissing the asses of people that want to overturn every part of the constitution that isn’t 2A rights. I’m slightly more okay with SAF and GOA, but they still often shill for Republicans.

    The fact that a gun has a ‘purpose’ of killing is reductive and not useful. Killing is, by itself, neither good nor bad. Killing can be justified and moral, or it can be deeply immoral.

    So, as I asked originally, if you could reduce the number of illegal and immoral uses of firearms without reducing the ability of people to exercise their civil rights, would you be open to that?

    Fewer guns doesn’t, by itself, mean less violence. We can see that in Australia and in England, where the combined rates of all violent crimes (battery, robbery, forcible rape, murder) are comparable to the US, and possibly higher, but the lethality is reduced. On the other hand, reducing the amount of violence in society, through programs that attack root causes in the most affected communities (which, notably, is not harsher policing and sentencing, but more like community improvement and poverty reduction), reduces both rates of violence and the homicide rates. Chicago actually had a pretty good violence intervention program going for a number of years before it was senselessly defunded.



  • Love that people just ignore that violence doesn’t happen in a vacuum, and since violence must happen in a vacuum without any causes at all the only solution is to remove the tools.

    Guns are tools. A knife is a tool. A car is a tool. Even high explosives are tools.

    BTW, I do have a kitchen gun, because that’s where I need it when there’s a problem bear outside. (Yes, bear - one of those 300+ pound animals with teeth and claws that are sometimes extremely aggressive.)

    I assume that you want safe communities; would you be open to solutions that increase safety if they didn’t involve removing firearms, or is that the only solution that you’d accept?


  • Obviously the problem is that there are too many knives in China, and it’s too easy for civilians to get knives! No one needs a knife; the only purpose of a knife is to cut and stab. The only solution is to completely ban all knives in China.

    …Or they could seriously address the social issues that lead to certain segments of their population committing this kind of atrocity.

    Hmmm. I wonder where else that could be applied…?



  • Depending on how you generate power, you could use LED grow lights in vertical farms. You also have the luxury of working in an environment that you can tightly control; that means you may not need to use pesticides or herbicide at all. If you aren’t working in large fields, you can get away from using heavy diesel farm equipment.

    Fundamentally, we need to use less land for farming, we need to use far fewer pesticides and herbicides, and need to reduce the emissions associated with farming. Vertical farming has the potential to help with all of those.
