Not to be confused with the 1600 meter or "1 mile" race which is commonly run in US track and field events (i.e. 4 times around a 400 meter track). At least that's within 1% of an actual mile.

"pigeon" and "dove" are both words for the same family of birds. The bird most people think of with the word "pigeon" is the rock dove (https://en.wikipedia.org/wiki/Rock_dove) or domesticated / feral variants of it.

Yep, but importantly "pigeon" and "dove" are not exactly interchangeable words, there is just no consensus for which is which.

Toads and frogs are another pair like this, where there is no clear distinction

True. But I did not ask about "pigeon" and "dove." I asked it about "pigeon" and "mourning dove" which are unambiguously different species. Different genuses, even. Zenaida macroura v. Columba livia.

Matrix exists and really isn't too bad to self-host if you just want a small number of people. (If you federate with other servers, then you have more things to worry about -- increased attack surface, more visibility leading to more potential attackers, and the risk of unintentionally storing illegal content (e.g. CSAM) sent by people from other servers.)

The UI of Element (the most popular Matrix client) is more or less in line with any other chat app, but I guess it depends what you mean by "on par to whatsapp". Biggest downside I've found is that you can't search your messages on the mobile clients.


My favorite weather map for SF is PurpleAir: https://map.purpleair.com/environment-estimated-temerature-f...

There are thousands of sensors around the city. You can get a sense of shade-vs-sun temperatures by the spread of numbers you see (on cloudy days, the reported temperatures will be much closer together, while on sunny days, sensors in the sun will report elevated temperatures.)

You do need to make sure to disable indoor sensors, and keep in mind that some sensors are faulty. (I've seen some that have been reporting a constant temperature for years.)


This one is neat, I might actually use it.

I don't understand why it includes indoor sensors at all let alone by default. Why would I want to know the temperature inside some random building?


> I don't understand why it includes indoor sensors at all let alone by default.

Add location_type=0 to only get outdoor sensors


or just click the buttons that accomplish the same thing. The point is someone at PurpleAir is asleep at the wheel if such an obvious default configuration isn't being set. If they can't get such a basic thing right, why do we trust anything else from them? "Anything else" specifically including "running their software on a raspberry pi inside my home network".

Because PurpleAir is not a weather service, they’re a sensor company.

The project is using PurpleAir data.

Footer should say "Data from PurpleAir API" instead of "Data from SF Microclimates API"...


I use that and Mr. Chilly.

Mr. Chilly is one of those niche apps that sparks joy and reminds me of the early app days.


This was directly inspired by Mr Chilly which was designed by my friend Anna Bleker.

It's an excellent iOS app: https://mr-chilly.com/

My goal was to do something similar as a Claude Code skill


I use Mr Chilly to demonstrate to non-SF folks how many microclimates SF (and the Bay Area has).

Only suggestion: separate Inner and Outer Sunset since there can be a massive difference between near Ocean Beach and near Irving/9th Ave in autumn (ie. SF's hottest season).

Edit: nevermind, just saw both inner_sunset and outer_sunset in /neighborhoods. I'd assumed it was merged based on the human readable list on the landing page. Thanks for the fun API!


thanks I will update the homepage to reflect this.

You call it passive aggressive, I call it "acknowledging that you might know something I don't".

I agree, and why I hate that this has become a thing. I encountered the same thing as the GP which is from where my experience comes. I'd ask "Why did you choose X over Y" as I'm genuinely curious to know what tradeoffs were considered that led them to choose X. Perhaps there's something I don't know. But I also see it get used all the time to mean "you should have done Y".

The "we" stuff is similar. There was a movement several years ago to try to remove blame/harshness from the tone of code reviews, and this is what we got out of it.

How does the Bedtime Bulb compare to Philips' "warm glow" bulbs, which also adjust their color temperature as they dim?


The Philips bulbs are more general purpose bulbs that would replace your "soft white" 2700K bulbs. I think they dim down to around 2200K. Otherwise, the specs are pretty typical for LED bulbs in terms of color quality, flicker, and dimmability.

Bedtime Bulb v2 starts at 2100K, much warmer, and dims down to 1700K. BBv2 has infrared. The flicker is very low: under 1% at 120 Hz; the best I have seen in any dimmable bulb. It is also designed to dim perfectly with all TRIAC and ELV dimmers (basically, any standard dimmer), which no other LED bulb can claim to do.

Side note: the term "flicker-free" is a total lie, so we stopped using it. I have seen lighting with up to 50% claiming to be flicker-free. Pretty much all lighting has some flicker. The term is just not true.


Sometimes it's about matching the fashion of the group you aspire to be part of, sometimes it's about having that fashion imposed on you so you look "professional".

Security guards at tech company offices are the only ones who wear suits, presumably because it's a mandated uniform, not by choice.


Apocryphal, but someone once told me history of male grooming is an example of this: When only rich people could afford to shave, the fashion among the noble was to have a clean-shaved face to signal status, and poor people had beards. Once safety razors appeared, then the trend reverted.


> On 23 October 2005, Finnix 86.0 was released. Earlier unreleased versions (84, and 85.0 through 85.3) were "Knoppix remasters", with support for Linux LVM and dm-crypt being the main reason for creation. However, 86.0 was a departure from Knoppix, and was derived directly from the Debian "testing" tree.[7]

My reading of this is that early versions of Finnix were based on Knoppix. However, according to the wikipedia sidebars, the initial release of Knoppix was 30 September 2000, while the initial release of Finnix was March 22, 2000. Something something beta/pre-release versions?


From the Wikipedia article:

> Finnix 0.01 was based on Red Hat Linux 6.0, and was created to help with administration and recovery of other Linux workstations around Finnie's office.[citation needed] The first public release of Finnix was 0.03, and was released in early 2000, based on an updated Red Hat Linux 6.1.

So it seems that it was based on Knoppix later


This is for a similar incident that happened in 2008, not the Jetblue incident from October of this year.


Oh my god, you are correct. I read the technical details and did not bother to check it's the same issue. I am mortified. Apologies.
