kpozin··on Updated Google Maps shows destruction of the city of Rafah
For comparison, here's Mosul in Iraq after the defeat of ISIS:

kpozin··on Immich 3.0
If Tailscale is on, I can't concurrently run a DNS-blocking local VPN, so I see ads in mobile Chrome.

kpozin··on Google Flow Music
Gemini's built-in song generator seems to have better prompt adherence, higher audio quality, and better diction.
kpozin··on Java.evolved: Java has evolved. Your code can too
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.
kpozin··on I was banned from Claude for scaffolding a Claude.md file?
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.

kpozin··on Denial of service and source code exposure in React Server Components
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.)

kpozin··on Installing a mini-split AC in a Brooklyn apartment
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).
kpozin··on 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(<precondition>, 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.

kpozin··on Fluorite lenses: Corrective capabilities beyond ordinary optical glass
> creating "aberrated(after Ernst Abbe)" color-shifted image at its focal point

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

kpozin··on Copilot key will eventually be required in new PC keyboards
What about the MS Office key and Emoji key? Those were definitely added after 1994.

kpozin··on C diff spores resist bleach and remain viable on surgical scrubs, fabrics
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··on Ask HN: Does your microwave interfere with Bluetooth? Mine does
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.)

kpozin··on Strong static typing, a hill I'm willing to die on
> read up on some catastrophic bugs. Those that have caused space ships to explode and cars to crash.

One of the most famous type errors in recent history did in fact crash a spaceship.

kpozin··on How to store a chess position in 26 bytes using bit-level magic (2022)
If you have the entire move history, then you probably don't need to store partial board positions.
kpozin··on Johnson and Johnson reaches deal for $8.9B talc settlement
Isn't talc still used in pills and tablets (e.g. magnesium supplements, Tums, etc.)?
kpozin··on Best printer 2023: just buy this Brother laser printer everyone has, it’s fine
The ChatGPT-generated section sounds exactly like the substance-free content farm articles you would find if you searched for "how to choose a laser printer".
kpozin··on So, you’ve been challenged to a duel. What are the rules? (2016)
As illustrated hilariously in the first episode of Norsemen.
kpozin··on Ask HN: Is it just me or is 5G strictly worse than LTE?
I have a Pixel 6A on T-Mobile. I keep 5G turned off because it's usually slower and flakier than LTE, visibly chews through the battery (a percentage point every couple of minutes), and heats up the phone.
kpozin··on A dinosaur with a remarkably preserved face
Some languages besides English have distinct terms for a human face vs. an animal face. Is that what you're referring to?
kpozin··on Stanford hates fun
My understanding is that universities in the U.S. often own much of the real estate around their campuses. (This is particularly true at Stanford; even faculty members who want to live nearby end up renting from Stanford or "buying" land leases.)
kpozin··on MDM: Human Motion Diffusion Model
A related paper by the same lead author:

"MotionCLIP: Exposing Human Motion Generation to CLIP Space"

https://arxiv.org/abs/2203.08063

Would anyone be able to explain how the two techniques are related?

kpozin··on Why does everything on Netflix look like that?
It's not just changes in aspect ratio (i.e. the shape of the frame). In Sandman, they compress the actual image, so everything looks stretched vertically.
kpozin··on Ask HN: Which book would you pick to re-read for the rest of your life?
Note that this concerns the studies cited in just one chapter (of 38 total) in Thinking, Fast and Slow. The chapter is about implicit priming.

kpozin··on Ask HN: Non-violent video games with great stories?
The new King's Quest (2015) is great action/puzzle game, with some fairy tale mischief but no significant violence. It's framed as a narrative by an elderly king and his granddaughter, and clearly intended to be kid-friendly.
kpozin··on Ask HN: Who wants to collaborate?
In a slightly different direction, I'd love to collaborate with someone on writing and producing low-budget short films in NYC. I have some plot ideas bouncing around, as well as some basic equipment and (mostly theoretical) skills in cinematography, sound, and editing.
kpozin··on AI could end foreign-language subtitles
I have a difficult time imagining that Russian speakers prefer the dubbed content they're offered. Most of the Russian dubs I've seen have one male voice actor doing all the characters (or with an additional female voice actor doing all the female characters, if you're lucky) with no attempts at timing, emotion, or intonation. The dub track is played on top of all the other audio, instead of being properly mixed in to replace the original dialogue track.
kpozin··on AI could end foreign-language subtitles
This is actually an improvement over stereo soundtracks, as you can just raise the relative volume of the center channel!
