DerekL··on Two conspiracy theories about cola
Who's Buffet?
DerekL··on Software for Math Research
That's probably because they wanted to use juxtaposition for multiplication. Otherwise, “f(x)” could mean either f applied to x or f times x in parentheses.
DerekL··on Captain Kirk: Bezos' Blue Origin to Send William Shatner into Space
No, Blue Origin really does go into space. But it's good to point out the huge difference between going to space and staying there.
DerekL··on Google developing own CPUs for Chromebook laptops
Google is doing this for Chromebooks. If they want to lock out other vendors from making Chromebooks, they don't have to make a custom CPU, they'd just have to fork Chrome OS and Android. But they don't want to corner the Chromebook market, they want wide adoption.

> And because they are not OEMing this hardware, they really have no incentive to be cooperative with the others. Similar to older gaming console that had custom and experimental architectures.

What exactly is this referring to? Are you saying that game consoles should only use chips that are available to other manufacturers, or that every game console should be an IBM-PC compatible, like the first Xbox.

DerekL··on Why Are Fast Food Workers Signing Noncompetes?
How is this relevant? The article does not mention McDonald's. Jimmy John's used to use noncompete agreements (not just no-poach), until they got sued.
DerekL··on Stephen Hawking Warns: Humanity May Have Less Than 600 Years to Leave Earth
Wow, how did he do that!?

Oh, it's an article from 2017.

DerekL··on Ask HN: Why Did Pascal Fail?
They're called “Pascal” and “Ada”. Not all caps, because they aren't acronyms.
DerekL··on Pumpkin OS: x64 port/re-implementation of PalmOS
That was the Newton, not Palm.
DerekL··on Commodore 64 Ads from the 1980s
Commodore should have been updating their custom chips at a much faster rate. The AGA should have been ready in 1988 or 1989, and the blitter should have been four times faster instead of twice as fast. I don't know if the problem was lack of investment, or what.
DerekL··on Pong Circuit-Level Simulation
Blip, made by Tomy.

DerekL··on Banach-Tarski and the Paradox of Infinite Cloning
> Until recently I never questioned the idea that, say, the positive integers and the odd positive integers are equivalent because they can be paired, but this cloning thing seems like something that falls out of that.

They really aren’t connected. The first statement (the positive integers can be partitioned into two sets, each of which has the same size as the original set) follows from the usual axioms of set theory (ZF), while the Banach–Tarski paradox cannot be proven to work without the Axiom of Choice or a similar axiom.

DerekL··on The CEO Trying to Build a Christian Secessionist Tech Industry
> There was no link this video in this article.

The Rand Paul was linked to in the first paragraph, “in a new video making the rounds on social media”.

DerekL··on One does not simply calculate the absolute value
Yes, using an existing implementation is a good idea, but why not just use std::abs?
DerekL··on C++20 Modules with GCC11
That joke doesn't even make sense. C++ modules aren't a package manager. They can't fetch code from a central repository.
DerekL··on Close you were to never happening (right to repair)
Actual title is “Here's how close you were to never happening.” Why remove “here's how”?
DerekL··on Abandoned Motorola Headquarters (2020)
Well, part of it is now. Google sold Motorola Mobility to Lenovo.
DerekL··on Abandoned Motorola Headquarters (2020)
It's not relevant to the article, which is about real estate. Also, the article mentions the split into two companies. Google bought Motorola Mobility, but the headquarters went to Motorola Solutions.
DerekL··on Amiga 500 replica is coming in 2022 for $140
It does include a mouse.
DerekL··on $28.50 Beer at LaGuardia Sparks Audit of New York Airport Concession Prices
Technically correct is the best kind of correct.
DerekL··on What Happened to the Democrats Who Never Accepted Bush's Reelection (2020)
That was the 2000 election. The article is about the 2004 election.
DerekL··on Private student loans can now be discharged in bankruptcy
Yes, it's an ad, but not clearly marked. The byline says “Sponsored by Credible”.
DerekL··on Ask HN: Which vintage computers do you find interesting?
After watching a video (https://www.youtube.com/watch?v=smStEPSRKBs), I starting thinking about writing for Atari’s “Quadrascan” vector graphics arcade machines. I wondered if they could play a primitive first-person shooter. You’d need to clip the drawing of partially-occluded objects, either by designing them in some clever way, or by adding clipping support to the hardware.

The easiest way to get started would be an emulator.

DerekL··on Ask HN: Which vintage computers do you find interesting?
I have the urge to write an Atari 2600 program to solve some of the recent Project Euler problems. I’ve already found that it’s feasible. The hardest part is input and output.

DerekL··on Rhode island makes financial literacy classes required for high school students
> An real home economics class - with personal finance as a primary focus

Home economics has always included a variety of household skills, and was never limited to just personal finance.

DerekL··on Some Americans are breaking out of political echo chambers
> Santa (Coke's version)

“The image of Santa Claus as a jolly large man in a red-and-white suit was the standard long before Coca-Cola co-opted it for their advertising.”

DerekL··on GNU Coding Standards: Writing Robust Programs
> Heaven help you if you wanted to develop in C++ on OS X, since Apple's packaging of GCC was a total disaster.

If you were developing Mac programs in C++ back then, you were probably using Metrowerks CodeWarrior.

DerekL··on Amazing documentary about taking the first picture of a black hole
In what way is it not a picture?
DerekL··on Steve Jobs on his “glide slope” theory of tech (1988)
In 1992 (just over 10 years after the IBM-PC was introduced), with version 3.1, Windows started becoming much more popular than MS-DOS.
DerekL··on There's a Hole at the Bottom of Math
Dupe: https://news.ycombinator.com/item?id=27248170
DerekL··on Google Says Everything at Stadia Is Fine, as the Water Reaches Their Noses
It's “Jaron Lanier”.
