Kagi Summary: The passage discusses whether photons, the quantum particles of light, have a finite or infinite lifetime. It explains that while photons can be created and destroyed through various interactions, they cannot truly be "ki

If something blocks the photon, that was "agreed" upon before the photon was created. A photon travels between an electron that emits it and an electron that absorbs it. These two electrons must agree on the photon transfer before

The trick to left-to-right subtraction is to write down the resulting difference right away, then "slash" through it to borrow from it. When I was designing my custom flashcard program, I played with around with different input me

So on paper: you write down 8 right away, and add an underline each time the next column results in a carry. When doing mental math on-the-fly: the carries may chain all the way back to the least significant digit, but most of the time you

Maybe SignalDB?: https://signaldb.js.org/core-concepts/#signals-and-reactivit... I swear I read that MeteorJS and/or MongoDB implemented signals for the DB layer. While searching for the source, I found SignalDB.

My guess is all the assets are preloaded. They are gradually added to the "stage" and shrunken/faded out based on the zoom level on an item-by-item basis (vs zoom levels.) The background color would be its own "item.&quo

How about going to a medical conference/event to meet doctors in person?

Consider the situation from your prospects' perspective: most likely your outreach is being lost in a sea of SPAM. I am not a doctor, but my university email was somehow put on a list of medical professionals. So now my university emai

Concepts from Functional Programming can be used to reduce the state space. First, do as much work as possible in pure functions. Pure functions can safely be run in parallel, in any order because they do not have side-effects. Then the sid

Supabase also offers data (DB as a service). I wonder if that means Supabase can solve the (separate) user storage problem[1]. [1]: https://threadreaderapp.com/thread/1651434348174778370.html
