I’m 40 and forcing students to do handwritten essays during tests has always been stupid. Typing is much faster, why bottleneck ideas by forcing handwriting?

Haven’t seen danluu stuff here for a while!

One way to reduce income may be to buy a bunch of stocks with high variance - for any that is in the red during the year, sell and rebuy them. Any that has a gain, leave them be.

There’s so many annoying bugs in Mac OS (like the screwed up window management and alt-tab not working properly), that the notch seems like an odd complaint at this point. The OS is fighting the user constantly, and there’s not much we can do…

It is true cost-benefit for public works projects include the public benefit. But it is often not magnitudes more. Often projects basically scrape by on cost benefits larger than 1.0, after some creative accounting.

And yes, the timescales are larger, but they are still tied to interest rates. A benefit on the scale in 100 years can not be measured over that timescale.

The share went up in as part of the streaming frenzy during Covid, crashed in 2022 like everything else, and has been flat ever since. Basically got a bump for Disney+ for a while, but didn’t create “shareholder value” besides that.

I thought it’s candid because the subjects’ reactions are honest, unrehearsed.

I bet the cost-benefit is actually negative. But it is kind of cool, I guess.

This is a strong argument for a broken status quo. It’s essentially dismissing many possible, tangible, in other places implemented approaches to improve representation, by essentially declaring that fixing the system cannot be done, or must first involve some completely new solution.

Looks like 256 color style imagery. It’s not perfect, but clearly based on that VGA style.

Arguably more of an optimization, rather than a fix. Looks like un-unrolling a loop, or better, rolling a loop. Or rolling straight line code?

The linked video seems to provide a much deeper story: https://m.youtube.com/watch?v=SZcrPM-jDqY&ra=m

Interesting. So if there's a merger of SpaceX and Tesla, he gets back more Tesla.

Well thanks to the 60 minute game play and no saves, you only ever see the first four/five levels or so. It’s a great game, but that particular mechanic is …kind of annoying.

Thank you for all the interesting references. I had almost forgotten about the BSP-SNES port.

I think they main concern when doing sectors + portals for a wolf3d-type 3d engine is how much word is done when 'stepping into' portals. basically it requires changing the clipping range [x0, x] of the portal, and quickly finding the next visible wall segment. the clipping could actually be done in 'angle space', not even using vectors. That is, wall edges/"vertices" should be represented as [angle,distance]. I have also been thinking about how much of that math pipeline could be done using specialized 8-bit values and LUTs.

I have been thinking about trying to get something running on very slow hardware, although at some point the problem is more drawing on the screen quickly, not the renderer.

WBGT != WBB

It really doesn't. I would argue that convex sectors with portals could be quicker than casting rays across a grid for every pixel column, except for some degenerate cases. This is because for any pixel column in-between the boundaries of wall segments, there's virtually no work to be done (O(1)), compared to the work of casting a ray along the grid O(n).

Btw, 286 played wolfenstein rather poorly. The 386 is rather more appropriate.

Wolfenstein was built in a couple of months by a then 21-year-old Carmack. He didn't focus on optimizing levels until Doom.

I personally am not a big fan of the banding effect due to small number of light levels. One way to reduce that would be to introduce a 2x2 dithering matrix grid across the whole screen that introduces small “luxel” deltas like 0.5, -0,5; 0.5, -0.5. Some pixels will be brighter, some darker, reducing the banding. Could also try different matrices.

The funny thing is that looking backwards, I would never use a grid of squares for a raycaster like wolfenstein3d did.

If I were to do a raycaster today, I would use convex sectors with portals, basically like duke nukem, but constant wall heights. You can do drawing very simply by just doing a linear pass across the sector, recursively stepping into other sectors.

Then you can at least do arbitrary level geometries.

Yeah, it’s more like a saturated blue giant circle.

Can't he just list his own shares but just keep holding them without selling.

I don't make any sort of claim of 'just fine'. I am saying there will be places and times where people cannot regulate their body temperature via evaporation, so they will die outside without AC within hours. And in Singapore that point hasn't been reached yet.

The point isn't that it's "just fine" right now, it's that it will get way worse.

Singapore is not mentioned in the wiki article on wet bulb temperature.

And given that the maximum ever temperature in Singapore is 35-36 for most months, I doubt that a wet bulb temperature of 35+ is common.

I was also going to mention wet bulb temperatures as well. As horrible as the conditions described in the article is, it describes a very dry heat. Which means sweating and water can still help.

The really scary thing will be when the wet bulb temperature goes above 35 degrees, and humans can only survive with AC.

Dav3d?

There's a 64MB game boy advance cartridge with shrek on it [1]. Looks pretty horrible [2]. But the GBA only has 16KB fast / 256KB slow RAM, and a 16MHz CPU.

I thought Prusa only has a five color print head switcher.

A statement that is obviously false cannot reasonably be “misleading”.

Because it’s a corporation doing the crime to an old man trying to pay for cancer treatment.

"All almonds are grown in the U.S. state of California." implies "No almonds are grown outside the U.S. state of California."

You find one almond tree outside of California that grows almonds, where such almonds are grown intentionally, and the claim is false.
