bewaretheirs··on CT scan shows there's still lots of toner left in an “empty” cartridge
It was reusable. You would turn it back to the start to reset it when you'd pull it off the top of the old filter and stick it on top of the new one.

I don't recall whether it came with the pitcher or as a bonus item included in a filter-multipack. It just counted one "tick" on a ratchet per fill/empty cycle, no attempt to measure volume or fractional fills.

At one point Brita distributed a spring-driven mechanical ratchet counter that would sit on top of the filter cartridge; it had some sort of diaphragm arrangement that would sense the water level and "tick" once per refill cycle and tell you when it was time to swap in a new filter.
bewaretheirs··on Huawei phones automatically deleting videos of the protests?
Always-on is qualitatively different from "only on for 10 minutes".
bewaretheirs··on Huawei phones automatically deleting videos of the protests?
I don't think anyone's claimed that was the case.

Apple isn't removing the only way to coordinate, but they are removing a mechanism which has reportedly been used by Chinese dissidents.

Just hope they never link up with the Emus after their decisive victory in 1932.
bewaretheirs··on Crypto’s Final Price Could Be Zero
Gold bugs.

But even without them its value would not go to zero; ignoring the purely aesthetic uses (jewelry, decorations, etc.,) elemental gold has a wide variety of uses including corrosion-resistant electrical contacts, dental fillings, etc.; the James Webb Space Telescope mirrors have a gold coating as it is a good reflector of infrared radiation.

bewaretheirs··on The erasure of women from online pregnancy literature
My understanding is that "differences in sex development" or "disorders of sex development" is now the preferred terminology. See for instance:

"Disorders of sex development, or DSD (previously called intersex), includes a range of conditions that lead to abnormal development of the sex organs and atypical genitalia ..."

bewaretheirs··on The leap second’s time is up: world votes to stop pausing clocks
My understanding is that clocks in Greenwich are set to utc+1 from the last Sunday of March until the last Sunday of October. (They call it British Summer Time).
bewaretheirs··on The leap second’s time is up: world votes to stop pausing clocks
That's a feature, not a bug. UTC adjustments require world-wide coordination.

Timezone adjustments do not. They are fundamentally a local matter, and just need to be communicated to the tireless maintainers of tzdata, and can happen incrementally any time an area feels local time is too far off solar time.

bewaretheirs··on The leap second’s time is up: world votes to stop pausing clocks
We actually live with about +/- 15 minutes of drift (of local solar noon vs. 12:00 local mean time) over the course of a year. See https://en.wikipedia.org/wiki/Equation_of_time

And timezones one hour wide impose about a +/- 30 minute fixed error (and sometimes larger) on top of that - the difference between local mean time and local civil time.

bewaretheirs··on The leap second’s time is up: world votes to stop pausing clocks
it's really just a tzdata update for the vast majority of computer systems. That package updates several times a year. Get the revised rule in there a decade in advance and you're golden.
bewaretheirs··on The leap second’s time is up: world votes to stop pausing clocks
The drift is sufficiently slow that you can fix it with a "leap hour" when needed -- perhaps once every five thousand years. This could be handled for civil/local time via an adjustment in the timezone definitions (something which happens a few times a year today), leaving the underlying UTC timebase unchanged.
bewaretheirs··on FTX’s balance sheet was bad
Unfortunately nobody has distilled accounting into a series of six-paragraph blog posts.

(see https://lithub.com/crypto-nerd-sam-bankman-fried-who-just-lo...)

“I’m very skeptical of books. I don’t want to say no book is ever worth reading, but I actually do believe something pretty close to that,” explains SBF. “I think, if you wrote a book, you fucked up, and it should have been a six-paragraph blog post.”

bewaretheirs··on Fossil species found living off southern California; notes on the genus Cymatioa
The linked paper refers to shells in "deposits" dated to between 28,000 and 36,000 years ago rather than fossils, so the species was known to have lived comparatively recently in geologic terms.
bewaretheirs··on The most unethical thing I was asked to build while working at Twitter in 2015
I would have thought that a mobile telco could generate this data already just from what they need to route data (and voice calls) to each phone, at least to a somewhat coarse level, without needing to have apps upload this.
bewaretheirs··on In defense of linked lists
Set two pointers to the head of the list.

Step through the list by one element per iteration with one of them, and with the other, step every other iteration.

If the two pointers are ever again equal you've found a cycle.

If you hit end of list, no cycle.

This is part of his "Legal Systems Very Different From Ours" which was originally a college-level course and is also available as a book.

bewaretheirs··on Flying the Unflyable Plane: The near crash of Air Astana flight 1388
The 2013 Proton crash was more similar to the Embraer incident than you might think. Human pilots can sometimes step outside the box and re-learn how to fly but automated guidance systems aren't that flexible.

The Proton crash involved angular velocity sensors -- rotational accelerometers -- installed upside down. It's not that it wanted to fly into the ground, it was that it couldn't fly straight because (from the guidance computer's perspective) it was responding backwards to the behavior commanded by the guidance system. And rockets just don't fly sideways very well.

Watch the direction of thrust from the engines (the Proton, like most rockets, steers by thrust vectoring) in this slowed-down video of the incident:

Well, you need both GWh and GW ratings for storage - how much fits in storage, and how fast can you add and remove stored energy.

Moreover there are increasingly strict restrictions on where it is permissible to smoke. To mirror rhetoric elsewhere in the thread: in many areas the state and local government is successfully cracking down on "open nicotine scenes".
bewaretheirs··on Gas Leak in the Baltic Sea
Methane is a significant greenhouse gas and I just don't see an attack that results in a large methane release being approved by the current administration. If they wanted to permanently shut the pipeline they'd do it differently.

bewaretheirs··on Ask HN: Discord banned me with no recourse
For many services, I think the right model would be analogous to how landlord-tenant relationships are regulated -- with significant constraints on how and when services can be terminated once they've started.

This should be the case even if the tenant isn't paying cash for services.

bewaretheirs··on Oscar Niemeyer’s French communist party headquarters
"inner party" is a term from the world of Orwell's "1984", but something similar existed in the Nomenklatura of the Soviet Union - an upper class of people in leadership positions who had extensive privileges not available to the average person or even the average party member.

It all looks as if, regardless of the ideology of the people involved, once it actually gets power, as-built communism in a one-party state ends up structured an awful lot like feudalism...

SpaceX is developing a version of its Starship intended to land astronauts on the moon as part of the Artemis program: https://en.wikipedia.org/wiki/Starship_HLS

Blue Origin worked on a "Blue Moon" lander and later teamed up with LockMart, Northrop-Grumman, and Draper on the ILV lander proposal.

bewaretheirs··on Ranking the 25 Most Painful Lego to Step On
1960's and 1970's lego wheels had a small embedded metal axle. Depending on orientation these could cause a significant puncture wound:

Never had any of these but I suspect this variant would be even worse due to the smaller area at the tip of the axle:

bewaretheirs··on Why are D-sharp and E-flat considered to be two different notes?
Related in a distant way:

https://news.ycombinator.com/item?id=31476078

my TL;DR, as a western classically-trained amateur musician largely unfamiliar with Indian music: Harmonium (a small reed organ) is widely used in Indian classical music but its use is controversial because it doesn't allow for the fine adjustments in pitch (roughly analogous to the D#/Eb distinction discussed here) that is seen as central to most/all Indian styles.

bewaretheirs··on Why are D-sharp and E-flat considered to be two different notes?
Yep. And - where musically appropriate - if you know which note of the chord you're playing, you can tweak the pitch towards the Pythagorean tuning and get the harmony to "ring" as the harmonics of each note reinforce each other.

This sort of hybrid tuning is common in barbershop quartet singing as well.

bewaretheirs··on Why are D-sharp and E-flat considered to be two different notes?
What I've seen is a thumb lever for the 1st valve, finger ring for the 3rd valve.
