If Tailscale is on, I can't concurrently run a DNS-blocking local VPN, so I see ads in mobile Chrome.

Gemini's built-in song generator seems to have better prompt adherence, higher audio quality, and better diction.

Maybe `ArrowLeft`/`ArrowRight` or `j`/`k` to flip through all of card pairs? Or just allow us to scroll through all the pairs. In either case, both old and new should be visible.

This happened to me a couple of times when I tried to sign up on their website: instantly banned before I could even enter the onboarding flow.

I then had more success signing up with the mobile app, despite using the same phone number; I guess they don't trust their website for account creation.

A framework designed to blur the line between code running on the client and code running on the server — forgot the distinction between code running on the client and code running on the server. I don't know what they expected.

(The same confusion comes up regularly whenever you touch Next.js apps.)

If you just want to be able to control the ACs remotely, without remote sensing, you can buy some cheap IoT IR blasters (around $15–30 for Zigbee or WiFi versions). They'll often have control schemes you can download for your specific equipment (cloning the IR remote control that came with the AC).

New comment by kpozin in "Journey to Optimize Cloudflare D1 Database Queries"

Another fun limitation is that a transaction cannot span multiple D1 requests, so you can't select from the database, execute application logic, and then write to the database in an atomic way. At most, you can combine multiple statements into a single batch request that is executed atomically.

When I needed to ensure atomicity in such a multi-part "transaction", I ended up making a batch request, where the first statement in the batch checks a precondition and forces a JSON parsing error if the precondition is not met, aborting the rest of the batch statements.

  SELECT
    IIF(, 1, json_extract("inconsistent", "$")) AS consistent
  FROM ...

I was lucky here. For anything more complex, one would probably need to create tables to store temporary values, and translate a lot of application logic into SQL statements to achieve atomicity.

This is a clever bit of folk etymology [1], but aberrate is derived from the Latin verb aberro, meaning to wander or stray [2].

Note:

> biocide-exposed spores were spiked onto surgical scrubs and patient gowns and recovery was determined by a plate transfer assay

The article says nothing about washing scrubs and gowns. They put bleach-treated spores onto fabric, did not treat the fabric, and then collected samples from the fabric.

kpozin — Thu, 05 Oct 2023 13:57:29 +0000

My data is anecdotal, but I've observed that Panasonic inverter ovens that I've used interfered in the 2.4GHz range, while models of other brands (e.g. GE) have not.

(This is unfortunate because Panasonic seems to be the only brand that can actually adjust power output, whereas the others simulate lower power levels by cycling on and off.)

If you have the entire move history, then you probably don't need to store partial board positions.
