cbr··on Google Memory Loss
Hmm. I just tried to reproduce this with old posts of my own and couldn't. I picked random phrases from five early 2006 blog posts that get basically no traffic and searched for them:

    "I had been playing the accordion Davy lent to
    Rosie during winter break"

    "The language they're using is not that different
    from the one I wrote PlayGUI to use"

    "I've been playing a decent amount of music lately,
     mostly guitar and piano."

    "warm dry socks was the most important aspect of the
    festival"

    "This wouldn't be that bad, if it was not exactly what
    happened a year and a half ago."
Google found all three. For each one there were either 2 or 3 results: first my old post, then one or two from rssing.com which seems to do something with my rss feed.

Trying them with Bing, it also found all five of my posts, and ranked them first in four cases. In the fifth case ("This wouldn't be that bad, if it was not exactly what happened a year and a half ago.") it ranked a goodhousekeeping.com post higher, which had all the individual words but none of the phrases.

(Disclosure: I work for Google, though not in search.)

cbr··on Google Memory Loss
Sites allow search engines to index them (instead of telling them to go away with robots.txt) because the search traffic is worth it to them.

Search engines don't allow people to scrape them (resorting to blocking after scrapers ignore robots.txt) because they don't get anything similarly valuable in return.

cbr··on What It Felt Like in Hawaii When Warning of an In-Bound Missile Arrived
If the alarm is as easy to trigger as pushing a single button, then issuing an update that it was a mistake should be designed for. Ideally just a couple presses, something that can be done in under a minute.

    I'm not a member of the church
I'm atheist, but if things were going horribly wrong LDS would be high on my list of people to be around.
cbr··on Birth Order Effects Exist and Are Strong
The survey asked for numbers of older brothers, younger brothers, older sisters, and younger sisters. The main analysis on the post is for people with one sibling, and there are exactly as many people with one sibling whose sibling is older as there are whose is younger.
cbr··on Monitoring Home Power Consumption for less than $25

    I am bombarded with ads on Facebook for the Sense. This
    device allows you to monitor whole-home power
    consumption. ... I realized it would be extremely simple
    to do something similar without any wires or hassle.
Sense monitors two things:

* instantaneous current

* instantaneous voltage

Different devices have different electrical signatures, and this allows it to learn what devices you have in your house. RTL-SDR is much too low-resolution for this.

RTL-SDR monitoring would actually be awesome to add to Sense: the method it uses for measuring current is designed for microsecond-level accuracy, not long-term accuracy like your meter. So over time they won't keep perfectly in sync. If Sense could automatically read your meter it could calibrate itself.

cbr··on NY lawsuit asks: Is graffiti art protected under federal law?
The quote "These individual artists may be compensated, but what is going to be the long-term effect [is] buildings don’t allow public art because they don’t want to face damages" looks right to me.
cbr··on A friend of mine died and I didn't know because of algorithms
> Families would call all the close contacts and relatives to make sure that they knew.

I think people generally still do this? When my mother died a few years ago we took turns calling her relatives and close friends. We wanted them to hear the news verbally.

cbr··on A tale of two bubbles, the dot-coms and Bitcoin
Generating a private key for a given public key is computationally infeasible with current approaches: right now you'd just have to brute force it. But if someone finds a vulnerability they might be able to cut that time down to where it's commercially viable to get the private keys. At which point there's no way for anyone to prove they're the true owner of an address.
cbr··on A tale of two bubbles, the dot-coms and Bitcoin
If a sha-256 exploit came out relatively suddenly, such that anyone could generate private keys for a given account key, bitcoin's value really would go to $0. I don't think this is likely, but I think maybe 1% over the next 10y is reasonable.

    this is the currently-accepted way of doing accounting
Cash basis is also accepted, and generally used by very small businesses where accrual accounting is too complicated.
cbr··on How do you move out of a smarthome?
Or just remove the thermostat from the wall, and turn the heating on by shorting the signal wires together.
cbr··on Don’t Tax Options and RSUs Upon Vesting

    if a company receives a bill for something they bought
    in 2016, but don't technically pay it until 2017, the
    bill would still show up in their 2016 reports.
Yes if you're using accrual basis, but not if you're using cash basis: https://en.wikipedia.org/wiki/Basis_of_accounting

(Any big company will be using accrual basis, though.)

cbr··on Flatiron School settles for operating without license, employment/salary claims
I've worked with bootcamp grads who have been pretty good, and hadn't already learned how to code. I also have friends who started out as non-coders, went through bootcamps, and are now doing really well.

cbr··on Disqus comments adding third-party ad-tracking
The feedback I was getting when I explicitly invited people to send me email wasn't generally that good, plus was a lot more hassle to respond to for less benefit. People can still find my email on my contact page, but pushing people to comment publicly has definitely been better.
cbr··on Three Paths in the Tech Industry: Founder, Executive, or Employee
It sounds like rent control isn't making this a fair comparison? We'd want to compare going out and renting a new studio vs 1/N of an Nbr.
cbr··on Three Paths in the Tech Industry: Founder, Executive, or Employee

    Not everyone is a student anymore.
I'm 31, married with two kids, and we have housemates. It's nice having more people around, in addition to being cheaper.

(We've lived in four places since getting married, one without housemates and the other three with. We've definitely preferred the latter.)

cbr··on Three Paths in the Tech Industry: Founder, Executive, or Employee

    what's cheaper than a studio?
Splitting a several-bedroom apartment several ways.

For example, where I live [1] a studio is $1,700 but one room in a 3br is $1,100.

cbr··on Disqus comments adding third-party ad-tracking
I deal with this in a weird way: people comment on fb/g+/hn/reddit and then I pull the comments onto my blog via a server-side script. For example, comments on my most recent post: http://www.jefftk.com/p/paypal-giving-fund

The (terrible) server-side code is https://github.com/jeffkaufman/webscripts/blob/master/commen...

cbr··on Disqus comments adding third-party ad-tracking

    there's no reason that a) needs to happen in a public
    comment and b) that you cannot provide an email for
    people to reach you at
I blog a decent amount, and I don't like getting emails about my posts. I'd much rather have the discussion publicly. When we talk in the open other people can contribute to and learn from the discussion. Putting lots of effort in a careful back and forth conversation with a reader is much less worth it if it's a private 1:1.

(If I wanted to talk about things where people couldn't be honest in public it would be different)

Color comes from the initial neural network step. Since skin color is relatively predictable from facial features (ex: nose width), it should be able to do reasonably well.

    big power hungry fan motor
Fans don't use much power. 50W would be fine for a swamp cooler for a tent. Are you thinking of on air conditioning compressor?
cbr··on How the GDPR Will Disrupt Google and Facebook

    If you follow GDPR strictly you would need to be
    able to purge the data from your backups.
    Now most backups are considered immutable, so
   you aren't going to do that
Encrypt with a user-specific key, and destroy that key to drop all backups concerning that user.
cbr··on Doomsday planning for less crazy folk
A "hundred year storm" doesn't mean we expect one per hundred years globally, but one per hundred years locally.
cbr··on Doomsday planning for less crazy folk

    its sewer connection was just the house pipe inset
    into the city pipe
That connection isn't too bad, but I'm curious how they dealt with water supply and (if they have it) natural gas? Those are much harder to make flexible.
