mjs··on Smallest particulate matter air quality sensor for ultra-compact IoT devices
Might need to wait a few generations. It costs ~30€ for a single unit (maybe half that at volume?). And not waterproof.
mjs··on MIT Aluminum Bicycle Project 1974 (2016)
> She did spend another year in France, but not until 1988/1989 with her husband, Sheldon Brown…

It's his wife! Harriet is Sheldon's wife!

mjs··on Useful built-in macOS command-line utilities
Does `open` give focus? It used to, but since a few releases ago the app opens in the background, which is pretty annoying.

My poor workaround is to use osascript: `tell application "System Events" to set frontmost of process "Finder" to true`

mjs··on FIDO Alliance publishes new spec to let users move passkeys across providers
The Yubico FAQ explains some of the history fairly well: https://www.yubico.com/blog/a-yubico-faq-about-passkeys/

In particular, they distinguish between "copyable" and "hardware-bound" passkeys. They're both passkeys, and can be used wherever passkeys are supported, but only the "hardware-bound" passkeys support attestation.

The FAQ on that site is useful too: https://gpsjam.org/faq/
mjs··on Airbus: A year with no fatal accidents
At least one hull loss will be in the 2024 report (but amazing it didn't lead to (commercial) fatalities):

mjs··on Monopoly Board Game
"This has led to the canonization of a number of house rules that make the game more palatable to children (and sore losers) …"
mjs··on GraphCast: AI model for weather forecasting
Looks like https://sites.research.google/weatherbench/ attempts to "benchmark" different forecast models/systems.

They're very cautious about naming a "best" model though!

> Weather forecasting is a multi-faceted problem with a variety of use cases. No single metric fits all those use cases. Therefore,it is important to look at a number of different metrics and consider how the forecast will be applied.

mjs··on Apple TV, now with more Tailscale
It … kind of does, but if you filter the reviews by "TV" you'll see there's quite a few issues with it: https://play.google.com/store/apps/details?id=com.tailscale..... Not sure why the back button issue hasn't been fixed, that makes it very inconvenient to set up. (Also: are you sure it can be used as an exit node? That wasn't supported a few months ago.)
mjs··on Hollywood movie aside, just how good a physicist was Oppenheimer?
A lot of these discoveries were also published in the same year (1905):

(General relativity was 1915.)

mjs··on Gravity Probe B
Gravity Probe B is my favourite example of scientists spending a lot of money and effort to verify something almost everyone believed to be true, because science.
mjs··on Switching from pyenv, rbenv, goenv and nvm to asdf
I also prefer `direnv`. I am not entirely sure how `asdf` actually works; `direnv` is pretty straightforward: it hooks into the shell and modifies environment variables. (`PATH`, but also tool-specific variables if required.) So it's pretty easy to debug or replicate by hand if necessary.

It can't actually install different versions though (looks like `asdf` can?), which is somewhat inconvenient.

mjs··on Meta might consider leaving Europe?
For a global company, Facebook has a surprising uneven distribution of data centers:

  - Continental US: 14 operating or under construction
  - Europe: 3 (all operating)
  - Everywhere else: 1 (Singapore, under construction)

Do you have a source for this?
mjs··on Apple Announces App Store Small Business Program
The way the rules are now seems like there's a very big incentive to avoid earning a little bit more than $1m. This could have … unintended consequences.

(e.g. if it looks like you're going to earn a little bit over $1m, increase prices by a lot (to discourage purchases), but tell people the app will be "cheap" again in January. Or even make the app free for a while.)

mjs··on Apple Announces App Store Small Business Program
There's no discontinuity in the first year you exceed $1m: that extra dollar is "taxed" at 30%, but the first $1m is at 15% ("the standard commission rate will apply for the remainder of the year").

Looks like the next year (after exceeding $1m) the first dollar will be taxed at 30%, though.

They should just make this work like income tax: the first $1m is taxed at 15%, and everything above that is at 30%. (Same rules every year, no flip-flop.)

mjs··on Which of these Amazon Prime purchases are real?
The more crucial difference is that the products were sold by third party sellers. I'm assuming counterfeit goods are almost never a problem if the seller is Amazon.
mjs··on Spamnesty – A Bot to waste spammers' time
Many of the replies seem like they involved at least some human effort, although it would be nice to be sure--I wonder if there's some way to introduce some spammer-appropriate text captcha into the exchanges?
mjs··on IBM Type
Given the comments here, you might want to call out more clearly that this is not the stable/final release of either the font or website to set expectations, etc.
mjs··on HTTP Immutable Responses
Chrome is not going to get this:

https://bugs.chromium.org/p/chromium/issues/detail?id=611416...

Instead, when the user attempts a full-page reload, Chrome will revalidate the resource in the URL bar, but not subresources (they will come from the browser cache, if the cache-control header checks out):

mjs··on Dismantled Tesla Model S found in truck
Can you get a Tesla serviced anywhere other than a Tesla dealership? Does anyone do this? Seems like it's going to be difficult to consistently sell $100k of Tesla parts for even 10% of their value.
mjs··on Stop using 'short' for line and allocation sizes (2013)
So has Linus learnt another editor, as threatened??
mjs··on Building a Bank with Kubernetes [slides]

Parent poster is Head of Engineering at the bank (not CTO?), and author of the slides.

mjs··on Visual Studio Code 1.5
Interesting, just received a 1.5.1 update. I wonder what happened to result in such a quick release. (Nothing in the release notes.)
mjs··on Servo Nightly Builds Available
The OS X binary isn't signed, and the download URL is HTTP. Is there a version available on a more secure distribution channel anywhere?
