This is probably beyond the author's control, but they shouldn't host it somewhere that can inject scripts outside their control (like Cloudflare) and then claim "privacy".

JonathonW··on Non-Euclidean Doom: what happens to a game when pi is not 3.14159 (2022) [video]
That'd pretty much be Portal; the technique he's using to render there is basically the same as the one Portal uses (the Portal engine can do "invisible" portals like this too, but there's only one point across both games where they're used in the finished game).

I suppose something around non-Euclidean levels without user-created portals could be interesting, but I think it'd be hard to flesh that out to a point where there's enough there for a whole game without coming up with some other gimmick.

JonathonW··on A ‘double brood’ of periodical cicadas will emerge in 2024
I was in Nashville for the last Brood XIX emergence (2011)-- where they actually emerge is pretty patchy, but they were pretty dense around my office building, to the point where you couldn't walk down the sidewalk without stepping on cicadas or cicada shells with almost every step. Went to an area renaissance fair that same month, and they were just about deafening in the forest around the site (thankfully weren't swarming too badly where people were, at least).

I'm not looking forward to this May. Not sure what to expect at home this time around (still in Nashville, but a different part of town)-- hopefully they're not too bad, but I suspect my noise-cancelling headphones will be getting a workout while they're out.

JonathonW··on Lead in gasoline blunted IQ of half the U.S. population, study says
Jet fuel does not use lead. I'm also pretty sure jet fuel never used lead; it has no reason to (jet engines are not particularly picky about what they burn-- jet fuel is basically kerosene).

Aviation gasoline does use lead-- it's used there to prevent predetonation (engine knock), which is bad for a car engine but really bad in something that's supposed to be keeping you in the air. Replacing it is an ongoing effort, but it's taking a while-- largely because of certification requirements, because it's pretty important to make sure that your new gasoline formulation isn't going to, again, make that thing that's keeping you in the air fail. And there are a lot of older GA airplanes out there that would need recertification for a new fuel.

JonathonW··on Boeing 777 loses tire while taking off from SF, crushing cars on the ground
The same companies that manufacture car tires-- Goodyear, Bridgestone, Michelin, and probably most of the other major manufacturers (but those three definitely all have aircraft tire businesses).

They're probably not cheap.

JonathonW··on I made a bad camera lens from some old glasses [video]
First project in my high school photography class (before we even touched anything having to do with a film camera) was to make and use a pinhole camera— body made of cardboard and tape, “lens” a piece of foil with a hole in it, and “film” a 4x5 bit of photo paper.

It’s a great way both to explain the whole premise behind photography (your fancy camera and lens is just an elaborate way to project an image onto a bit of light-sensitive stuff that you otherwise keep in the dark) and to give students some early hands-on experience developing prints without all the intervening steps involved in making a print from film.

JonathonW··on Hetzner switches to new billing model
Hetzner's US cloud zones are colocated in someone else's facility (AFAICT they don't specify where): https://docs.hetzner.com/cloud/general/locations/#are-the-se...
JonathonW··on Let Everybody Sing (2016)
Churches of Christ frequently use shape notes in hymnals as a sight-reading aid, and they almost all sing a capella, but the style and arrangements are usually very different than what you'll hear with Sacred Harp-- more melody-focused, like a conventional choral style.

(I grew up in the Church of Christ and what I've heard of Sacred Harp sounds pretty chaotic to my ear, even arrangements of hymns I know well. But it's an interesting sound, and it's probably fun to participate in.)

JonathonW··on The Fed is behind the Capital One/Discover merger
In the US, merchants spent years actually being forbidden (by the networks' merchant agreements, and even by law in some states) from adding a surcharge onto credit card transactions.

That's mostly gone now (although I think there are still a couple states that forbid them, Visa and MC at least allow a credit card surcharge or cash discount in their merchant agreements), but it's so normalized at this point that customers are unlikely to care that CC and cash transactions are the same price. So, if you're a merchant, you set your pricing to include your merchant fees and just take the extra profit on cash transactions.

JonathonW··on F-Zero courses from a dead Nintendo satellite service restored using VHS and AI
This was the Nintendo Gateway System, and it looks like there really was SNES hardware at each seat (actually physically combined for each group of two or three seats, but installed at the seats, not some central location): http://videogamekraken.com/nintendo-gateway-system

Also related to the LodgeNet system that showed up on hotels around the same time, although that did use a centralized set of SNES cards rather than SNES hardware for each room.

JonathonW··on Proposed top-level domain string for private use: ".internal"
Yes, the classic not-interoperable approach of publishing the protocol as Standards Track RFCs with the IETF.
JonathonW··on Tart: VMs on macOS using Apple's native Virtualization.Framework
How recently have you tried it? The current best-performance option for bind mounts in Docker Desktop on macOS (VirtioFS, using Hypervisor.framework) didn't become the default until June (for new installs) or September (for existing installs), and wasn't available at all prior to December 2022.
JonathonW··on Modern iOS Navigation Patterns
"Save", "Discard" (or "Don't save"), and "Cancel", where "Cancel" does not dismiss the editor.

(This is the three-button close prompt that's been the standard in desktop operating systems since at least the Windows 3.1 era, but I guess we have to rediscover these things when the same problems come up on mobile.)

JonathonW··on Secrets of the Fn Key
A handful of these have been present for years (they weren't new in Monterey)-- specifically the ones replicating keys that are not present on Apple's laptop keyboards (Fn+Delete for forward delete, Fn+Up for page up, Fn+Right for Home, etc.).

The ones that map to OS functionality (rather than to other keyboard keys) are definitely new-ish, though-- like Fn+H to show desktop, or Fn+M for the Apple menu.

JonathonW··on Who makes the most reliable new cars?
Everything on the 12V system essentially is powered from the traction battery (the big one that can power the motors), once the car is turned on.

In Toyota, at least, the traction battery is completely disconnected (via a relay) when the car is off. The 12V battery is needed to power anything on the 12V system up until the car starts-- that includes the car's computer, which is what (after doing all its self-checks and whatnot) activates that relay and connects the traction battery to everything else in the car.

The traction battery isn't always connected probably mostly for safety reasons (having 400-someodd volts energized across the whole car even when it doesn't need it isn't great), but that also keeps it from getting excessively drained if something in the car malfunctions. It's pretty cheap to replace a 12V lead-acid battery if it's overdischarged after you left the lights on... the big hybrid battery, not so much.

JonathonW··on In 1903, NY Times predicted airplanes would take 10M years to develop
The article says nine weeks before.

The NYT article mentioned is in their archives [1], dated October 9, 1903, which would be 9 weeks and 6 days. Close enough, although I'd probably round up to 10 weeks.

JonathonW··on CIA: All Foreign Governments
> immigrants make up about 87.9% of the total population

The makeup of the native population probably isn't unbalanced-- rather, women aren't coming to the UAE to work.

JonathonW··on Right turn on red? With pedestrian deaths rising, US cities are considering bans
What? Right turns being generally permitted on red (after stopping, while yielding to traffic that has the right of way) does not mean you "cannot prohibit right turns under any circumstances"-- there just needs to be a sign prohibiting them (or a red right arrow means the same-- you may not turn right while it's lit, although around here you'll usually see that paired with a sign because people are stupid).

Cases where it's prohibited are plentiful, usually in cases where a right on red can't be executed safely (like if there's poor visibility around a corner) or if right on red would be disruptive to traffic flow.

JonathonW··on Asahi Linux goes from Apple Silicon port project to macOS bug hunters
There is no EFI on Apple Silicon. It's a more iOS-ish pre-boot environment (based around iBoot and some other Apple-y things).

There's also not exactly a boot picker in firmware-- that lives in the recovery OS. Which will also be unbootable if you're impacted by this issue because it's a minimal macOS environment; if your only OS is 13.6/13.6.1, that recovery partition will also be 13.6/13.6.1, and, if you have upgraded to 14.0/14.1, that installer can fail to update the recovery partition and leave it at 13.x (whatever you were on when you upgraded).

JonathonW··on Use YouTube to improve your English pronunciation
Don't worry; English pronunciation can be mastered simply through tough, thorough thought.

(English "o" is tons of fun-- of the 22 vowel sounds listed on the English orthography page on Wikipedia, only two can't generally have the letter "o" involved.)

JonathonW··on “Inverse vaccine” shows potential to treat MS and other autoimmune diseases
The US and Europe haven't vaccinated for smallpox since the early '70s and routine vaccination wrapped up globally in the mid-'80s, so, for many... absolutely nothing.
JonathonW··on NSO group iPhone zero-click, zero-day exploit captured in the wild
On Apple's end, iMessage also supports email addresses as a user identifier (and it's the only one you get if you don't have an iPhone with an assigned phone number).

It's still not sending emails, though. The iPhone Messages app sends SMS, MMS, and iMessage; email is the responsibility of the Mail app.

JonathonW··on Never Ending September Date
Already does that-- `sdate --covid 19` will keep it perpetually March 2020. It also accepts arbitrary starting points with `--epoch`.

Not sure how you'd do a perpetual 2020 while allowing the month to advance-- pretty simple if you keep the month as a number, I suppose, but problematic for the named months used in the examples (what should the 44th month of a year be named?).

JonathonW··on Replacing the bad flyback transformer in Apple's Studio Display 17"
It'll depend on your usage pattern and local cost of electricity-- if you're running that device that uses 10W more power 24/7, that works out to 87.6 kWh of additional power usage over the course of a year, or about $15 at the current average cost of electricity in the US ($0.17/kWh as of June 2023). If that's a monitor, you'd have to run it for a pretty long time before your break-even point on purchase cost alone (10+ years on a lower-end monitor, and probably not in your lifetime on something from Apple).

If your usage isn't continuous (which it probably isn't), that'll reduce your electricity cost and extend your break-even point even further; if electricity costs more in your region, it'll shorten it (average EU energy prices are around double that of the US IIRC, and some countries are much higher). But it's still going to take a while to break even if the efficiency improvements you're considering are in the 5-10W ballpark; that's not all that much power in the grand scheme of things.

JonathonW··on Visualizing every job in the world
Sex workers are generalized as "escorts", yes: http://data.europa.eu/esco/occupation/db20c08e-819e-4410-91e...

It's not clear to me how a porn actor or stripper would be categorized, unless incorporated in the more general categories of "actor" and "dancer" respectively.

JonathonW··on Zenbleed
The parent commenter seems to have figured this out, but to clarify a bit for posterity: build-essential does not come with nasm on Ubuntu (or upstream Debian, AFAICT). It has to be installed separately for the Zenbleed PoC to compile (if not already installed).
JonathonW··on HDR QR Code
What you're seeing here is Apple's EDR implementation [1], which, on non-local dimming displays (every Mac display except the M1/M2 14" and 16" MacBook Pros and the Pro Display XDR), works by bumping up the whole display brightness (and adjusting brightness of all non-HDR content downwards) to display colors brighter than standard SRGB white.

So, yeah, both QR codes probably are brighter on your old Pro, if its display brightness is set higher. And, if you adjust display brightness on the Air, you'll see them converge to the same brightness there, too (on my M2 Air, it seems that Apple leaves a little headroom for the HDR "white" to appear a bit brighter than UI white at full brightness; not sure if the M1 Air behaves the same or not as it has an older display).

Displays with local dimming (and OLEDs) can display, in small areas, colors that are brighter than the maximum full-screen brightness. That's where HDR content gets really compelling-- if all you can do is dim the whole screen, you're unlikely to see much of anything that you couldn't do just by bumping up the brightness with SDR content.

JonathonW··on Sennheiser HD 555 to HD 595 Mod
Or it might not work at all (as was the case for mine when I tried it).

There definitely was a period where AMD was shipping three-core Phenom IIs with a functional fourth core (demand was higher for the three-core SKUs than their actual defect rate appeared to allow), but I don’t know how plentiful fully-functional one’s actually were. And it was never guaranteed.

JonathonW··on Blink 1.0
Correct-- Blink needs a (reasonably) POSIX-compliant system to compile and run, so it should work on Linux or BSD or macOS, but needs Cygwin on Windows.
JonathonW··on Modern CPUs have a backstage cast
SNES games? You could comfortably run Windows 95 within the L3 cache on many recent Intel processors (the one in my 2019-era MBP has 16 MB of L3 onboard; current generation processors go even bigger and Windows 95 only needs 4 MB).

It's not really clear to me from the limited bits of info that I've read whether or not L3 is guaranteed to be accessible when doing CAR, but, if it is, you've got enough memory available to do a lot of stuff. (And even the L2 cache is starting to get pretty big on the higher-end current-gen chips.)
