DerekL··on uxn: a portable 8-bit virtual computer
By the way, portability was only a side effect of the Z-machine. The main purpose was code size. A text adventure compiled down to the Z-machine would take up less space than the same program compiled to machine code. They were written in the Zork Implementation Language (ZIL), which is similar to Lisp.
DerekL··on IBM creates 2nm chip
> I think it's important to remember that for instance Zelda: Link's Awakening was less than 512KiB in size and ran on a primitive 1MHz CPU.

The Game Boy CPU ran at 4.19 MHz.

DerekL··on Your Brain on Tetris
(1994)
DerekL··on Tetris-OS: An operating system that only plays Tetris
The Atari 2600 has no BIOS or any other built-in ROM. Maybe you're thinking of the 5200 or 7800?
DerekL··on Technologies I thought my son would never use
> Both are digital, of course.

By the way, it annoys me that the word digital is used to mean “downloaded over a network”.

DerekL··on The Computational Expressiveness of a Model Train Set: A Paperlet
Yes. In fact, Dr. Nim uses the same mechanism as Digi-Comp II, which is also mentioned in the blog post.
DerekL··on Arm says latest Huawei chip not subject to US export controls
Explained in the article:

> Cambridge-based Arm uses intellectual property originating from both the US and of non-US origin, a staff member told Yicai Global at the Arm Vision Day.

DerekL··on Neo-Geo Assembly Programming for the Absolute Beginner (2016)
The Atari 7800 used the same idea of making everything a sprite and having no dedicated tilemap layer.
DerekL··on The FBI Should Stop Attacking Encryption
It was 66%. Most adults, but less than “almost every”.

DerekL··on 1991's PC technology was unbelievable (2011)
An Amiga outputs either NTSC or PAL, depending on the region it was made for. So with the right cable, you can just plug it in to a TV made before the mid-2000's. Later models also supported VGA.

DerekL··on 1991's PC technology was unbelievable (2011)
> if I recall correctly, while it had standard 3.5" diskettes, it couldn't read/write DOS disks.

The Amiga floppy drives took standard 3.5" media, and they could read MS-DOS disks, but the software for this wasn't included with the OS until 1992.

Section 9.7 in http://www.faqs.org/faqs/amiga/introduction/part4/ says you could do this with Workbench 2.1, which was released at the end of 1992 (http://www.gregdonner.org/workbench/wb_21.html).

DerekL··on The decline of computers as a general-purpose technology
I'm confused. What does this comment have to do with the article?
DerekL··on Modern Slavery from Arise VS
The title on HN uses the word slavery. The actual tweets do not.
DerekL··on C++ Anti-Patterns
There's a new formatting library in C++20. Unlike printf, it's type-safe, and it's extensible to new types.
DerekL··on A recording-studio mishap shaped '80s music“
The title should have “(2017)”.
DerekL··on A review of endianness bugs in Qt, and how they were fixed
> It's the same kind of thing as computers and calculators switching from decimal hardware to binary hardware 100 years ago.

Not quite. ENIAC, for example, did calculations in decimal, and it was finished in 1945. There may be more recent examples.

If you include binary-coded decimal, that still includes machines made in 1970 or later, like the IBM 1401.

DerekL··on Uber will charge significantly more per trip as new Seattle law goes into effect
Title should be “Uber will charge 25% more …”
DerekL··on Homebrew: AVX instructions in Big Sur bottles crash when run in Rosetta 2
The Apple Neural Engine is separate from the CPU; it's not additional registers and instructions for the CPU, like a vector unit. You go through the Core ML framework to use it, just like you go through Metal or OpenGL to use the GPU.
DerekL··on ATT services down due to bombing in Nashville
The title is misspelled. It's “AT&T”, not “ATT”.

Also, that's not the title of the article, though it is factually correct.

DerekL··on Ask HN: What Lived Up to the Hype?
Even though their early work sounded like everyone else at the time, it was brilliant. It wasn't just hype.
DerekL··on Mile-Long Wooden Xylophone Plays Bach in Japanese Forest
You're comparing one of the best, most-influential games on the NES with a rush-produced cash grab on the Atari 2600. There were many better games on the 2600. Also, the NES came out six years later than the 2600, so it's way easier to make more detailed and more interesting games for it.
DerekL··on Why FSF Endorsing PureOS Matters
But expansion packs are usually sold inside the game. The term in-app purchase is imprecise.
DerekL··on Jet Powered Volkswagen Beetle – $550k (sunnyvale)
This was the subject of the first episode of MythBusters.

DerekL··on Windows for Arm on M1 Mac Successfully Virtualized
> Nintendo consoles have never had powerful hardware though.

Not quite. Their last three consoles (Wii, Wii U, and Switch) were about a generation behind their competition, but the first four (NES, SNES, Nintendo 64, and GameCube) were comparable to their rivals.

DerekL··on To do politics or not do politics? Tech startups are divided
Of course, it's not just San Francisco, it's practically all cities in the Bay Area that strictly limit housing development but allow office construction.
DerekL··on Emojis paved the way for UTF-8 everywhere
I don't think that die faces are emojis. They range from U+2680 to U+2685.

Let's see if they work here:

Edit: No, they were filtered out.

DerekL··on Treat artificial light like other forms of pollution, say scientists
Yes. Normally, motorcycles aren't that loud, compared to cars. The owners specifically modify them for that.
DerekL··on No, C++ still isn't cutting it

DerekL··on I reverse engineered McDonalds’ internal API
Yeah! Whatever you do, never eat pretzels! They dip them in oven cleaner before baking, then they sprinkle them with those crystals they use for removing ice from roads!
DerekL··on Letter to 20 Years Ago
By the way, the abbreviation of advertisement is ad, not add.
