rpearl··on Tech elites leaving San Francisco threaten Silicon Valley's supremacy
The rest of that paragraph says: > beyond a select few, similarly expensive places.

Nobody's putting Boston and NYC on the list of cheap places to live, any more than SF.

That said, someone in a different part of this thread brought up Chicago, which seems plausible! Though I haven't been there enough to know if that's true! (Though when I visited, their transit definitely was very good).

rpearl··on Tech elites leaving San Francisco threaten Silicon Valley's supremacy
Nobody really brings up that the bay area is one of few places in the US where you can live without a car. Really, even compared to other "walkable" cities beyond a select few, similarly expensive places.

Nobody really brings up that the bay area has better LGBT and other minority protections than anywhere in the US, either. Every time someone mentions cheap midwest cities I have to pull up https://crossingenres.com/out-in-the-united-states-where-can... and see if anything's changed since I last checked.

Nobody really brings up the general art and culture scene in SF and Oakland. Or access to extremely high quality produce and food.

Generally nobody brings up the possibility that some people _want to be here_ outside of their jobs. It's weird.

I guess most of those that want to be here don't really comment on articles like this.

rpearl··on Ruth Bader Ginsburg has died
cool.

where's Justice Merrick Garland, then?

rpearl··on The Three Bay Areas (2017)
Alameda (East Bay) went 78.7% to Clinton plus another 6.6% to third parties

Santa Clara (South Bay) went 72.2% to Clinton plus another 7.2% to third parties

San Francisco went 85.0% to Clinton, with another 5.7% to third parties

So yeah, painting a picture of three people of different economic backgrounds, it would not be illustrative to make even one of them a supporter of the current regime.

rpearl··on We thought it was just a respiratory virus
they're not _independently_ reaching similar conclusions months apart, they're strengthening (and writing about) the same conclusion from the same and more data.
rpearl··on We thought it was just a respiratory virus
The article is a summary of research findings over the course of the pandemic. What makes you think the research is happening in a silo? it's not. Medical researchers, just like, uh, that guy you saw on YouTube, are quite capable of reading the research on nih.gov and capable of discussing and sharing findings with each other.

The article even says "By June, clinicians were swapping journal papers, news stories, and tweets describing more than three dozen ways that COVID-19, the disease the coronavirus causes, appears to manifest itself."

rpearl··on WHO Director: "Covid-19 does not transmit as efficiently as influenza"
Not quite... You'd need to catch a bit over half of all cases _before they passed on the virus to anyone else at all_ to bring R0 below 1 in this fashion.

the results of the test indicate whether quarantine and contact tracing are useful.
rpearl··on Twitter – “we are strongly encouraging all employees globally to work from home”
You wouldn't go to ER, even as a positive test, unless you needed intensive care. Most cases could be isolated at home.
rpearl··on Twitter – “we are strongly encouraging all employees globally to work from home”
if we knew the identities of all or most of the current cases, we could isolate them, trace their contacts, and thus slow the spread giving our systems more time to prepare by letting us allocate resources more effectively instead of reacting to critical cases only.

here is an analysis of the percentage of contacts we would have to trace (paramerized on R0), to stop the spread entirely. https://www.thelancet.com/journals/langlo/article/PIIS2214-1...

(We're probably past that point now, though)

rpearl··on Twitter – “we are strongly encouraging all employees globally to work from home”
the current federal administration does not operate with the well-being of the general public in mind.
rpearl··on Google employee diagnosed with coronavirus
On the other side of it, there's selection bias--most identified cases have visible and notable symptoms, some very severe.

If you have a mild cough or a bit of a cold, you might not think anything of it beyond staying home from work, but that could be COVID-19 (and we might _never_ know that it was).

We've been cyborgs much longer than that! Writing is a very old auxiliary memory mechanism.

current SSDs are page/block oriented, but that's likely to change. (See intel's relatively recent Optane).

rpearl··on IPv6 xmas display uses 75 Internet's worth of addresses
No, it's not, it is many, many times larger than 'usable v4 space'. Like, if each of the hypothetical 10^27 displays was given a single IPv4 address we'd run out and still need to assign billions of billions of displays.
rpearl··on Tetris
Nowadays, usually tetris random is actually done by "randomly shuffle the bag of 7 pieces, then deal them out", which isn't the same as randomly selecting a piece.

With that, and the hold functionality (also not around in this article, or at least not discussed) you can play indefinitely without any random chance, modulo reaction time.

rpearl··on My Parents Give Me $28k a Year
that's a simplistic analysis that doesn't really capture the whole effect a universal basic income might have. For one, with a livable basic income, the value of housing shifts somewhat--since there's not essentially a requirement to have a job, the demand for housing-near-jobs changes. It is hard to predict exactly what direction that might shift in.

The competitive environment around an artistic endeavor changes too--you have the ability to experiment and fail and not be forced out entirely, since you can fall back and change things up without having to worry about finding a job. And it might not be the case that everyone looking for a creative outlet is looking to make it into a living.

rpearl··on How can Bitcoin stabilize if it's a Keynesian Beauty Contest?
some amount of inflation is a desired property to have in a currency, and this result is for the most part the intended result
rpearl··on Commuting by Bicycle is down?
My commute is down market st, 4th to Castro, which is particularly bad. I bike. What happens is that at _every_ major market st crossing, cars will run their red (actual red, not yellow), and then stop just before the crosswalk due to pedestrians beginning to cross. They'll remain stopped in the middle of cross lane traffic for essentially the entirety of the light (Hey, if they didn't get to go why should anyone get to?!) , though sometimes they'll try to wedge themselves through pedestrian traffic, because driving a car turns people into assholes and necessitates neglecting the safety of others. It is possible that pedestrians might not notice this nearly as often, due to being much less impacted by it. It's also a significantly worse problem during typical commute hours.

Due to the number of aggressively awful drivers in the city, I've ordered a dashcam for my bike, so I'll likely have some footage to demonstrate this soon. (Well, I hope not, but.)

rpearl··on Commuting by Bicycle is down?
On Friday I decided to count the number of drivers running reds, since everyone gives cyclists a hard for doing so.

My commute in San Francisco involves crossing 16 streets. It's not very far, about 2.5 miles.

On Friday I observed 35 cars run red lights--not even "it's yellow and time to speed up because drivers don't give a single flying crap about safety" but literally the cross traffic lane is green.

Cars are a terrible unsustainable mess, ruining the environment and ruining city livability. It's not surprising that the risks they impose on the rest of the world are resulting in less people willing to bike

rpearl··on Google Scientist Resigns Over “Forfeiture of Our Values” in China
That's a super, super weird formulation here. First from the abstract standpoint, the math here is not right. Discussion: https://pastebin.com/qqQ3KGS5 because I don't want to divert from the more important point.

More importantly, you've failed to account for the externalities, entirely. It's not just a bet ("pay for a chance"). Trying the bet--in this case, allowing government censorship to control search results--has complicated to quantify, but significantly negative human rights cost.

So to summarize: I wouldn't think twice about taking your bet--I absolutely would, because the chances are absurdly in my favor (see the pastebin). But I--and generally, the people protesting this--would decline a bet that actually has the right stakes, even if there is a payout.

Okay, go for it then. Good luck!
rpearl··on Power Worth Less Than Zero Spreads as Green Energy Floods the Grid
the point is that "just consuming" the electricity is nontrivial. Suppose you've been paid to take some number of megawatt hours of energy. Okay: What do you do with it? At the least useful, you have to safely convert it into heat it without damaging something. More useful would be storing it. If you know how to solve that, yeah, you will make money.
