Thought 1: Hey, yeah, cool.

Thought 2: Wait, do they use more electricity than the rendering the same scene without a lamp? Is it just the background effort of the having the computer on, not the lamp itself? Hmm.

Thought 3: Calculating real-time lighting is one of the computationally expensive parts of modern video games, and power draw goes up with computational load, so adding a lamp to a scene plausibly does make rendering that scene use more electricity. So, yeah, cool.

Even with the cheapest simplest light model: A lighter room draws a white, rather than black, screen – achieved with more electricity.

eggman-is-fat-mkay:

Only if you’re using an OLED or one of those fancy multizone LCD panels that are actually more trouble than they’re worth. OLED screens work by starting from black and adding light you do want. LCD screens work by starting out with a bright white screen and filtering out all the light you don’t. They’re not perfect at this which is why OLED screens get deeper blacks. Fun fact! This is also how those cool “snowblind” PC cases work – they’re just LCD screens without a backlight.

Your average run-of-the-mill LCD will use exactly as much power displaying a plain white screen as a black one.

Also, barely tangentially related, but I just want to share a fun fact. You know those blinking nametag keychains they sell in gift shops?

6303e63f4502d81f1c959e5bcd4bfd7b5b30be9e

these?

they’re actually LCD screens with a single massive segment! the name is actually a printed page behind the LCD panel, which applies power to turn the LCD cell opaque and make it black. that’s why if you cover the solar cell on the top with your finger, the name stays showing and gets dimmer, and doesn’t completely disappear unless it has power.

If your desktop’s LCD screen works the way these do (some draw power on white, some on black), a plain black screen may in fact draw infinitesimally more power.

Very funny. This is clearly just someone’s cat–

Wait. Zoom in. Enhance. Ahhh, I see now.

AK-47 Type 1 (based on Avtomat Kalashnikova pattern, chambered in 7.62x39mm)

You can tell it’s a Type 1 (one of the original production models of the classic AK-47) by the following traits:

b7b6caa8e1bf45a643e7fee627fab80303c27d36

Some people believe that the AK-47’s loose tolerances make it more resilient to malfunction if it gets dirty, which isn’t really all that true. It is, however, a firearm that functions fairly well on very little maintenance.

Which, that’s impossible for a cat, of course. So definitely a gun and not a cat.

absolute-immunities:

ever since I learned about the “turned comma,” the rotated comma type that typographers once used as a superscript “c,” Michael G. Collins, M‘Culloch and the Turned Comma12 Green Bag 2d 265 (2009), I can’t help but notice when people get it wrong

Justice Kagan, for example, got it wrong in Kahler v. Kansas, No. 18-6135, slip op. at 2 (U.S. March 23, 2020):

0df86f5e02c2aa2beccaa0321fe02b20c15c0ec4
5b7f1aa59997b2852399e92bd18ff24dc0fc20ec

but it’s actually M‘Naghten’s Case (1843) 10 Cl. & Fin. 200, 8 Eng. Rep. 718 (HL), as the report reveals:

179bcd9baa196089956d4675d7c7228f7d9d7d9a

word processors can’t rotate type, but we could approximate the “turned comma” much better if we used a single open quotation mark (‘) instead of an apostrophe (’), as Justice Kagan does here

or we could just use “c,” as we do for McCulloch v. Maryland17 U.S. (4 Wheat.) 316 (1819), even though the report reads:

i insist that the loud noise is the one thing that separated vacuuming from being best sensory experience possible to the worst sensory experience possible. imagine vacuuming if it’s completely silent. it would be so much fun it feels like a beast on a leash swallowing up everything in its way indiscriminately it’s so awesome

it works without any batteries or electricity; it’s just a little flippy cylinder wheel that pushes dust and garbage into the little side containers, but for that it works remarkably well; I was pretty surprised at how big some of the stuff it picked up was

we use them to sweep the carpeted dining hall at work and they’re pretty fantastic for that although they don’t work well on tile and you’ve got to empty the traps decently often for maximum effectiveness; I don’t know how well it works for house floorjunk as opposed to dining hall floorjunk
