jimworm··on Missing businesswoman urges ex-husband not to publish book critical of China
> I don't think the CCP would be so petty to come after you abroad for something like this.

Maybe you don't know about LIHKG posters being attacked in the UK [1]. The CCP has teams of operatives working overseas specifically for this purpose [2]. If they will physically attack you for writing a few posts on a forum, you should certainly expect to be murdered by "car accident" while raising funds for a $100 million film.

Short term weaknesses can make long term advantages irrelevant. Actually it's the primary force that shapes history.
jimworm··on Security Threat Model Review of the Apple Child Safety Features [pdf]
But in that case they would eventually be caught red-handed and won't get to do the "for the children" spiel and get it swept under the rug like it's about to be.
jimworm··on Climate change: IPCC report is 'code red for humanity'
This looks a lot like what I was thinking of. They don't provide much information about their extracting filter, but after the CO2 is extracted it is compressed into water creating carbonic acid, then injected it into a suitable basalt formation with an impermeable cap so that carbonate salts could form[1]. They claim all the injected CO2 could become carbonates in under 10 years[2].

If this works like they say, then it's cause for hope.

jimworm··on Climate change: IPCC report is 'code red for humanity'
Trees with their own conversion capacity are indeed a good interim solution, but in the long term this form of carbon storage isn't as permanent as rocks, especially given how prone trees are to dying and decaying in the biosphere of today. The Devonian didn't have that problem. For example, parts of the Amazon have become greenhouse gas emitters even when human-caused deforestation is discounted.

There's also the very real possibility of forest fires releasing huge amounts of carbon at once. Even dead trees preserved in peat bogs could burn and release carbon in this manner.

Rocks have their own weaknesses such as ocean acidification, but relatively speaking they're much more stable.

jimworm··on Climate change: IPCC report is 'code red for humanity'
For all the carbon capture that the Devonian/Carboniferous period did over 100 million years, humanity undid a large part of it in 150 or so years. And now to preserve human civilisation in some form, the most direct way is probably to rebuild that carbon sink within a much shorter time. Much shorter than 150 years, not 100 million.

Current carbon emissions are over 10 billion tonnes per year, so the capture speed will have to exceed that by however much required, probably something like 10x as much. If a process could be scaled to capture 100 billions tonnes of carbon per year, it could be a viable way out of the mess.

Is it even possible with current technology given unlimited funding and political will? For example, if insoluble carbonates could be synthesised from atmospheric carbon dioxide, that could be a form of long-term carbon storage.

jimworm··on 'Do Not Split': A Hong Kong protest film [video]
The whole point of "not splitting" is a lesson learned in 2014, to continue showing support for the goals no matter the methods seen in protest. Nobody knew whether another in the group is an agent provocateur or a genuine radical. Nobody knew who were throwing the molotovs. Nobody even thought that the protest was likely achieve any its goals. The only thing that could not be faked is the sheer volume of people showing up; nobody could pay that many people to show up at a protest.

Therefore the only thing they could do is to keep showing up in support of the demands for as long as they could personally afford to do so, and try not to pay attention to the methods of others when they already knew that all methods were probably going to fail.

jimworm··on The GameStop Mess Exposes the Naked Short Selling Scam – The American Prospect
As a layman, it looks like failures to deliver have very little consequence, so I'll ask some stupid questions here.

If one of these activist investors happened to have lent a stock out, which then failed to deliver, what is the worst consequence they could inflict on the borrower? If no consequences are available, then how do short squeezes happen?

jimworm··on Element (Matrix chat app) suspended from the Google Play Store
They have to be happy on average. It's like being in a race where all the competitors started running in different directions, but eventually finding that the others have turned around to follow your target, effectively giving you a head start.

To spell it out more clearly, here is a great place for one's opponents/competitors to be stuck in - authoritarian enough to eliminate any advantages of liberty, but not authoritarian enough to be efficiently coordinated.

jimworm··on World’s biggest iceberg heads for disaster
The iceberg is very large, so even if it doesn't envelop the island it could create a detour of up to 140km between a penguin and its feeding waters, a 280km addition to every trip - and that's only if it has access to satellite images to plan its route. On the surface, that penguin would only see a huge wall of ice with no indication which way would be shorter.
jimworm··on China blocks Wikimedia Foundation’s accreditation to WIPO
My view is rather different. Written Chinese does not "belong" to Mandarin or any other spoken Chinese language, but is its own entity.

While the mainland-China version of simplified Chinese is based around Mandarin, written Chinese is most definitely not Mandarin. 裏 is not 里. 只 is not 隻. 后 is not 後. They might sound the same in modern Mandarin but that is where the similarity ends. Those are characters with entirely different meanings and often different pronunciations in various forms of Chinese.

I believe that alone makes the assertion that traditional Chinese is "just another character set" as controversial as calling English "just another Newspeak".

jimworm··on Japan confirms coronavirus infections without symptoms
Depends whether the targeted antigen has changed. Best case (for humans) is if it couldn't escape the targeting without deactivating the virus.

RNA viruses do change quickly, but influenza's probably on a different level with its multi-segment, randomly assorted genome.

jimworm··on Hong Kong Protestors Take over Universities and Financial District
Attempted to enter the dorms to arrest nobody in particular, without a warrant. After seeing the past few months' video evidence of police brutality, fear and resistance seem somewhat justified.

Personally I haven't yet imagined a way out that satisfies all sides. The fear of police seems deeply ingrained in the population and no current or former protester believes they would be treated fairly if the movement abandons any of the demands. The government, fearful of reprisal from the ruthless Beijing elite, are unwilling to grant any concessions to the protest demands. The police are also deeply fearful of an independent judicial investigation into their activities, and must maintain a state of disorder, increasing the government's dependence on police so that they will not launch an investigation. It seems like the situation has reached a Nash equilibrium and the whole ship is doomed to continue sinking.

jimworm··on Reddit, where chaos thrives, tries to clean up to attract ads from big brands
What are those "big brands" willing to accept? If their ads appear on a different sub to those they consider objectionable content, would that be considered sufficiently "clean"? Is there a value placed on moderation, and if so, how much value is captured by individual moderators and how will it be allocated?

Perhaps the most important factor in these communities is that most content is junk anyway, requiring mental effort from the reader to remove and avoid. That's what the whole voting thing is for. An advert would be "superjunk" - unwanted content that also has editorial control. It might be an illusion that a community is full of value to be skimmed off, when reality is that the junk is at barely maintainable levels and a little more might push it over the brink.

jimworm··on GM fungus can rapidly kill mosquitoes that spread malaria, study suggests
I was justifying my preference for the gene drive compared with the fungus. The fungus has potential to evolve independently to do different things, the gene drive does not. QED.
jimworm··on GM fungus can rapidly kill mosquitoes that spread malaria, study suggests
I'd much prefer the (theoretical) gene drive.

Bad outcomes for gene drive are either that it doesn't work, or the mosquitoes go extinct in nature and cause more ecological issues by their absence. The worst problem is fixable by keeping live specimens for reintroduction. In fact, since malaria is the target and not the mosquitoes, reintroduction might be a good idea after malaria becomes extinct.

Bad outcomes for the fungus is it becoming uncontrollable and starts killing other insects. Reintroduction becomes impossible without engineering a new, immune mosquito. Or that evolution backfires on the spider and causes them to go extinct. Or all of those happening together.

Comparing the two, the fungus has all the downsides and more, with zero upside.

For me, the more shocking discovery in that article is that there are actually organisations that consider genetic screening for Down's Syndrome to be eugenic discrimination.

Although people with Down's syndrome have a high likelihood of passing on Down's syndrome if they do have children, inherited cases are extremely rare.

jimworm··on International System of Units overhauled in historic vote
The NIST explanation of Kibble balance calibration includes this:

> Everything on the right side of that equation can be determined to extraordinary precision: The current and voltage by using quantum-electrical effects that are measurable on laboratory instruments; the local gravitational field by using an ultra-sensitive, on-site device called an absolute gravimeter; and the velocity by tracking the coil's motion with laser interferometry, which operates at the scale of the wavelength of the laser light.

Current is measured in amperes, derived from the charge (in coulombs, defined from the charge of a proton) and time (in seconds, defined from the vibration of a Cs atom). Gravitational acceleration is measured in ms^-2, derived from length (in metres, defined from the distance travelled by light in a vacuum in a second) and time. Velocity is also derived from length and time.

With these new defined constants (including the Planck constant), all of the instruments could now be calibrated by observing natural phenomena and a whole lot of counting.

jimworm··on Why Did China’s Biggest Movie Star, and the Interpol Chief, Vanish?

jimworm··on Women's Pockets are Inferior
Pockets cost money to make, and therefore could be removed to cut costs if buyers do not value them. Do men value pockets more than women?

Speaking as an owner of very few items of clothing, just one item with inadequate pockets causes a lot of inconvenience, so my tolerance for them is zero. Manufacturers of inadequate pockets can wipe this segment right out of their market - although I only have evidence to confirm segment size of 1.
