cbr··on A 2:15 Alarm, 2 Trains and a Bus Get Her to Work by 7 A.M
Building codes aren't the problem, it's zoning. If a developer had an empty acre in SF or Palo Alto, or permission to replace low rise housing with skyscrapers, they'd build.

The cost of building probably does have an effect on the margin, but it is so much less of a factor than restrictions on what can be built.

cbr··on 83 percent of Bay Area renters plan to leave, says survey
One way to handle this would be with a reverse mortgage. Effectively, the $30k/y of taxes are counted against the value of the home when it's sold. Since the home has gotten enormously more valuable (which is why the taxes would be higher) the homeowner still comes out very much ahead.
cbr··on Hard Lessons in Living Off the Grid

     He wanted to be a pioneer, a leader of some sort.
     This was more important to him than "saving the
     planet." His goal of going off grid was to position
     himself as a hero, a frontrunner. Instead of being
     happy that the island is converting to solar at a
     pace that exceeds its stated goals, he just feels
     cheated of his goal of being a role model.
That's harsh. If you put hundreds of hours into doing something you thought was really valuable, and it turned out that it wasn't actually valuable, I think you'd be sad too.

cbr··on Outraged about the Google diversity memo?
Given "men typically giving themselves credit for work done in teams while women typically talk about the teams they were part of", then if you see a female CV it's more likely to be understated than if you see a male one. Which predicts two things:

* People aware of this will prefer otherwise identical CVs with female names (expectation is the underlying candidate is stronger, just more modest)

* Blind hiring will get you more men (because hiring managers can't correct for the male/female difference in self promotion anymore)

cbr··on Google Fires Employee Behind Controversial Diversity Memo

    ALL the people interviewed are qualified, they can ALL do the job
I've interviewed ~100 people at a top tech company, and I really don't think this is the case: the best candidates are much better than the worst ones, even in on-site interviews. The signal isn't perfect, but it's pretty strong.
cbr··on Why We Can’t Have the Male Contraceptive Pill
I was also curious about this. A male contraceptive that is incompatible with drinking would be a good fit for many people who don't ever drink, including me. There would definitely be people it was a poor fit for, but it still seems like there's a teetotalers market. The main question to me is whether it's compatible with the small amounts of alcohol that are in many foods.
cbr··on Update on Bitcoin Cash
You can withdraw to a paper wallet without opening an account. You generate a new keypair, initiate a withdrawal from coinbase to your public key, and then can get both XBT and BCC from the private key later.
cbr··on Update on Bitcoin Cash
Before the fork they wrote:

    Q: Do I need to withdraw my BTC from Coinbase?

    ... If you wish to access your coins on the UAHF
    chain ... you should withdraw your BTC from Coinbase
    to an external wallet address under your control by
    July 31.

cbr··on Bitcoin Cash and a Critical Alert for Bitcoin Margin Traders

    Q: Will Coinbase keep UAHF coins for itself?

    A: No.

    Coinbase does not intend to support or interact
    with the UAHF chain. If this were to change,
    Coinbase would make those coins available for
    customers to withdraw, not keep them.

cbr··on Microsoft Paint to be killed off after 32 years
I remember dithered fills being in Paintbrush itself, using Windows 3.1. My memory is you had 16 colors to work with, and to get more than that it supported dithered colors. You could have, say, a red/yellow checkerboard. The UI let you treat these like other colors: you could save them, and draw with them. When you did that, each pixel in your BMP would be set to of the 16 allowed, but the overall impression would be of more than 16 colors.

To see this, go to https://classicreload.com/windows-31.html and then open Accessories > Paintbrush.

cbr··on The Myth of Drug Expiration Dates
$765B is their estimate for all waste, not just wasted pills:

    ProPublica has been researching why the U.S. health care
    system is the most expensive in the world. One answer,
    broadly, is waste — some of it buried in practices that
    the medical establishment and the rest of us take for
    granted.  We’ve documented how hospitals often discard
    pricey new supplies, how nursing homes trash valuable
    medications after patients pass away or move out, and how
    drug companies create expensive combinations of cheap
    drugs. Experts estimate such squandering eats up about
    $765 billion a year — as much as a quarter of all the
    country’s health care spending.
Later on they say:

    Tossing such drugs when they expire is doubly hard. One
    pharmacist at Newton-Wellesley Hospital outside Boston
    says the 240-bed facility is able to return some expired
    drugs for credit, but had to destroy about $200,000 worth
    last year. A commentary in the journal Mayo Clinic
    Proceedings cited similar losses at the nearby Tufts
    Medical Center. Play that out at hospitals across the
    country and the tab is significant: about $800 million
    per year. And that doesn’t include the costs of expired
    drugs at long-term care pharmacies, retail pharmacies
    and in consumer medicine cabinets.
This isn't estimating the same thing as the GP's $330M (hospital waste instead of consumer waste) but $800M is on the same scale, suggesting to me that the marginal cost of drugs might matter some.

(I do agree with your point that most of the cost, and especially the most egregious examples like the wasted epi-pens, don't represent real costs because of monopolies.)

It compresses and optimizes png, gif, and jpeg, creates webp for browsers that support it, inlines small images into your html, longcaches images, and even creates srcsets.

cbr··on Unicode is hard

    In order to maintain backwards compatibility with existing
    documents, the first 256 characters of Unicode are identical to
    ISO 8859-1 (Latin 1).
This isn't true in a useful sense. It does look like it's true in Unicode codepoint space [1] but in any specific encoding of Unicode it can't be the case because latin1 uses all 0-255 byte values. For example, in utf8 it's only an exact overlap for bytes 0-127 (7 bit ascii).

(Though maybe this means you could convert latin1 to utf-16 by interleaving null bytes with the latin1 bytes?)

Regardless of preferences, what I'd expect to happen is that this would end up pretty balanced. Are a substantial fraction of high status women deciding not to get married? Much more than the fraction of high status men?
