mbrubeck··on The technology to eradicate mosquito-borne disease exists
Aedes aegypti is a non-native invasive species introduced by humans in the places where these efforts are taking place (including the entire Western hemisphere). They are not essential to native food chains here.
mbrubeck··on A forecast of the fair market value of SpaceX's businesses
But why should the fairest price be equal to exactly 12 months of earnings? Why not 1 month, or 100 months?

Is there something special about the length of Earth's orbit that makes it the correct ratio for converting flows to values? If a business were incorporated on Mars, would the fair price be one Earth year of earnings, or one Mars year of earnings? (The latter price would be 88% higher.)

mbrubeck··on An Introduction to Writing Systems and Unicode
Thanks, I missed that 将 was shinjitai. I wonder what caused the weird mixture of glyphs in that example image.
mbrubeck··on An Introduction to Writing Systems and Unicode
Can you clarify which characters you're talking about? I don't see any examples of Japanese-specific kanji in the simplified Chinese examples.

For example, the first image uses 沟 and 时 forms that are found only in simplified Chinese. In both Japanese and traditional Chinese, these are written 溝 and 時.

The images also correctly use the Chinese forms of 統/统. The Japanese form [0] differs from both and does not appear in these images.

请 as shown in the image is similarly used only in simplified Chinese, not Japanese. In Japanese, the traditional Chinese form is normally used in handwriting, and an alternate form of the 訁 radical (different from either of the Chinese forms) is often used in printed text.

mbrubeck··on Ode to the AA Battery
The comment above is about non-rechargable lithium-metal batteries. You are thinking of rechargeable lithium-ion batteries.
mbrubeck··on Rust's Block Pattern
There's some active work recently on fixing blocking issues, e.g.:

mbrubeck··on 'A full-blown crisis': Americans brace for a surge in healthcare costs
So first you say it has always cost this much, but in the next breath you say that its cost has outpaced a high rate of inflation. Mathematically, these can't both be true.
mbrubeck··on NaN, the not-a-number number that isn't NaN
We're commenting on an article about IEEE 754 floating point values. Following the IEEE 754 standard, we have:

    >> isNaN(Infinity)
    false
    >> Infinity == Infinity
    true
    >> Infinity / Infinity == 1
    false

    >> isNaN(0)
    false
    >> 0 == 0
    true
    >> 0 / 0 == 1
    false
Also, you say NaN ("not a number") is "defined as a number" but Infinity is not. I would think every IEEE 754 value is either "a number" or "not a number". But apparently you believe NaN is both and Infinity is neither?

And you say 0 / 0 is "undefined" but the standard requires it to be NaN, which you say is "defined".

mbrubeck··on NaN, the not-a-number number that isn't NaN
> two equal numbers divided by themselves equal 1

That's not true. For example: 0 == 0, but 0/0 != 1.

(See also +Infinity, -Infinity, and -0.)

mbrubeck··on Websites are tracking you via browser fingerprinting
From over a decade ago, a paper on then-commercially-available browser fingerprinting tech, including a study of its deployment in the wild:

mbrubeck··on Rust compiler performance
Oops, thanks for the correction.
mbrubeck··on Rust compiler performance
In versions earlier than 1.88, garbage collection required the unstable -Zgc flag (and a nightly toolchain). But in 1.88 and later, automatic garbage collection is enabled by default.

Automatic garbage collection of old build artifacts* is coming in Rust 1.88 (currently on the beta channel, will become the new stable release in two weeks):

*EDIT: For now this only deletes old cached downloads, not build artifacts. Thanks epage for the correction below.

mbrubeck··on U.S. sanctions cloud provider 'Funnull' as top source of 'pig butchering' scams
In both of those cases the designated entity was incorporated in the US (KindHearts in Ohio, AHIF-Oregon in Oregon).
mbrubeck··on Icônes
In words like icône in French, ô is typically used where the original Greek uses ω (omega).

mbrubeck··on Frink
units.txt defines `water` like this:

    water := gram / cm^3     // Standard density of water (defined)
1 g/cm^3 is the maximum density of water at standard pressure (1 atm), which it reaches at 3.98°C.

(Or at least, that used to be true by definition. Using the current definition of the kilogram, and the latest measurements of water density, the maximum density is actually closer to 0.99997 g/cm^3.)

mbrubeck··on Tech unemployment in the US drops to lowest level in more than two years
You keep posting this, but the official US inflation numbers do not claim 0.3% year-over-year food inflation (and have never claimed that at any point in the past several years):

This has been pointed out to you more than once, so at this point I assume you are deliberately lying and not just badly confused:

mbrubeck··on Mercator: Extreme
"Lines of constant bearing" (or "rhumb lines") depend on the choice of poles.

A rhumb line relative to true north looks straight on a standard Mercator projection, but can look like a spiral on another Mercator-style projection where the pole and center-point have been swapped.

mbrubeck··on TCL's bet on screens that look like paper
It sounds like it is dual-mode / transflective, based on the description of the button that “turns the display into an e-ink format” with ”a huge increase in battery life, up to 7 days of reading.”

It’s about as old now as the original Mac 128k was during the G4 era.

mbrubeck··on Engineer eats efficiently for $2.50 a day (2016)
No, the Consumer Price Index for November 2024 showed inflation of 0.3% over the last month. CPI inflation for food over the last year is 2.4%.
mbrubeck··on Engineer eats efficiently for $2.50 a day (2016)
No, the Consumer Price Index shows (seasonally-adjusted) inflation of 0.3% over the last month. The increase for the food category over the past year is 8× higher than that.

mbrubeck··on Starlink Direct to Cell
You can initiate a conversation with anyone while you are connected via satellite. But you do need to set up an emergency contact and/or Family Sharing Group if you want to connect via satellite and receive messages that were sent to you while you were offline.

(I’m referring to the "Messages via Satellite" feature that launched two months ago in iOS 18. This is different from the "Emergency SOS via Satellite" feature that has been around since 2022.)
