My guess: it is a relatively safe compound with the right properties to act as a working fluid for this movement. The text linked below mentions the working fluid and the property that the vapor pressure is highly variable over the range of normal room temperatures.

Here is a document with details and history about these clocks: https://www.physics.rutgers.edu/~matilsky/documents/Atmos/At...

What is a spec but a collection of decisions?

Camping gear, hammocks, bags, any small change or repair. Strap breaks on a backpack, fix it. Pocket rips, fix it.

The fact that it arrives cold and soggy is now an evolutionary pressure on our cuisine.

You can grow them yourself. I had no effort producing more than I can use in only a few years time.

New comment by Cerium in "How fast is N tokens per second really?"

Cerium — Wed, 20 May 2026 18:43:16 +0000

Why is that? It seems the other direction? I want to be sure I can complete a task in a certain amount of wall clock time. If the tokens per second are slow, then I am risking more by running a single approach at a time, and then have an incentive to try to multiplex my attention between separate work-streams. If the generation is fast enough to occupy my attention then there is no more available improvement by having parallel threads.

The main focus of education as a taxpayer supported activity is about the perpetuation of the state. The fact that a healthy state relies on a healthy economy is a constraint that helps shape the aims of public education. Other constraints are about culture, values, and understanding the government to the degree that the government can count on having a future generation of legislature.

One of my favorites on this topic, the 1963 "A Talk to Teachers", by James Baldwin.

Some perspective: I feel that I participate here, yet most days I don't write even a single comment. When I comment I rarely write more than two comments a day.

Agreed - my experience mirrors this.

> "Fix the following compile errors. When done, test your work and continue iterating until build passes without error" -> same cost but it gets the job done.

A good friend of mine holds the belief that "having friends with kids is better than having kids of your own", and I definitely feel the "can't explain" part - there is an unexplainable reality when you have kids of your own.

When you have a hammer as big as an LLM a lot of problems start to look like nails.

The second image in the article clearly shows screw holes in the letters. The H appears to be perfectly symmetric for 180 degree mounting.

Do it! Making a pie might seem unapproachable, but it will all work out. I have never failed to make a pie that brought some happiness into the world.

I don't see the lock in effect (such as learning a language, or a complex software product) with LLMs yet that would drive student based marketing efforts.

It is not really cheap, nor best "value for the dollar", but I am extremely satisfied with UniFi [0]. Nearly instant setup, decent mobile apps, web interface, basically just works as you need.

If you wanted to pay for direct air capture of CO2 to directly "undo" your climate effect of driving, the cost would currently be about $6 per gallon. Price comes from [1], found [2] looking for a second opinion on current direct air capture cost.

I interpreted the effect here not to be on the deck plates but to be the point of impact between the cable and the hook. Sudden bends in cables can wear them fairly quickly in the immediate vicinity. I'm sure you can extend cable life proportionally to the spread of the loading.

Hand tool woodworking. Zero screens needed. All you need is about a 8x8 foot space that you can get messy.

There is also Quadro Toys. I have a couple of the large sets and have built a series of houses, climbing toys, and now a "castle" with a slide for my daughter.
