DerekL··on VR porn a no go for Apple Vision Pro users as capability blocked by Apple
This is false. VHS had the advantage of larger cartridges, which allows longer recording time, which is especially important for time shifting TV shows (and not at all important for porn). Also, JVC licensed VHS to other recorder manufactures, which lowered prices and increased the number of available models.

Also, why would porn not be available on Betamax? You never needed a license from the format owner to prerecord tapes.

DerekL··on How Doom didn't kill the Amiga
Apple switched to PowerPC a few years before the NeXT acquisition and Steve Jobs' return.
DerekL··on How Doom didn't kill the Amiga
Yes, if Commodore wanted to compete, the Amiga chips needed to keep up with Moore's Law. Every 18 to 24 months, the processing and display power should double or more. In 1988, the Amiga 500 and 2000 should have had something like AGA.

The article correctly points out that 68k chips fell behind the x86 series. Yes, chunky pixels are useful, and the display hardware should support them. But if the game requires the CPU to draw each pixel one by one, the hardware has already failed. Instead, there should be some specialized processors that do the work. In fact, that's what happened in PCs. Doing all of the drawing with the CPU lasted only about five to seven years, then everyone had GPUs.

Yeah, it might not have saved power, but it did allow the machine to spend time on useful things.

The title is misspelled. Speed limit is two words.
DerekL··on Turning an iPad Pro into the Ultimate Classic Macintosh (2021)
You can't show animations with e-ink, because the refresh rate is very low. How would you even show a mouse pointer?

Note that that function has a sleep parameter. It doesn't return until an event has arrived or the sleep time has elapsed.
DerekL··on Apple hiring compiler developers for improving Swift / C++ interoperability
Yes, it's not a first class language, but the parent explained why it can't be. If you tried to implement a dynamic library with a C++ interface, you can't add virtual functions to later versions of the library without breaking any clients that derive from those classes. You'd have to recompile all apps any time you made a change to the OS.
DerekL··on Late 70s and 80s: forget BASIC, we had Pascal and C
By the way, the original Atari models, the 400 and 800, did not have BASIC built in. (They may have been bundled with the BASIC cart, I don’t know.) Subsequent models had it built in.

Title is misspelled, it should be “Ram”, not “RAM”.
DerekL··on What can you do with an Einstein (aperiodic monotile)?
You can't. First, here's a lemma:

Given three distinct lattice points (points with integer coordinates) A,B,C in the plane, either ⦟ABC is a right angle or tan ⦟ABC is rational.

Proof: Assume that ⦟ABC is not a right angle. If either line AB or BC is vertical, rotate the plane by 90°. Then at least one line is horizontal, and the other can't be vertical, because ⦟ABC is not a right angle.

Let x and y be the angles AB and BC make with a horizontal line. Then ⦟ABC = |x - y|. The tangents of x and y are rational, because the points have integer coordinates. Then |tan ⦟ABC| = |(tan x - tan y) / (1 + tan x tan y)|, which is rational.

The hat has angles of 120°, and tan 120° = -√3, which is irrational, so you can't draw the hat with lattice points, no matter how you scale or rotate it.

You can do that in modern C++, except that you have to create a lambda and assign it to a variable.

DerekL··on The importance of cash in a technological society
The US has a $1 coin, but stores never give it back in change, using $1 bills instead. Some vending machines do give it back in change.

DerekL··on Moonbase Alpha Travel Tube Details
These tubes only connect various locations of a single base, they don't cover the entire moon. The longest trip is probably only a few kilometers.

Rockets are more expensive, require more maintenance, and consume fuel or reaction mass.

DerekL··on Why did the Motorola 68000 processor family fall out of use in PCs?
VHS beat Betamax mainly because the cassettes were larger, allowing for longer recording time.

From the article:

DerekL··on D.C.'s ban on cashless businesses takes effect
It looks like many stores cut down on robbery opportunities by not having a cash register. They don't give change back, they only give store credit if you don't pay in exact change. That way, they can just put each cash payment in an envelope and drop it into a time-locked safe. (I imagine that they would do that, I don't know for sure.)
