Not really. Any solar system proves a kind of stability. And so does the famous KAM theorem. It states that a periodic solution is indeed quasi-stable under small pertubations. And yes, small sometimes is extremely small. But still stable. Imagine a sharp point with a tiny dent.

We used GitHub/Azure markdown plus Mermaid plus MathJax for financial model documentation. Beyond a certain complexity this really hurts.

Now we use typst, both playground (which does not call home, so no document exfiltration) or the compiler. The compiler is super easy to install, as we already have the Rust build chain installed. Compared to Tex, the 40 odd years newer design of typst makes all the difference.


How did you integrate Mermaid in the new Typst workflow?


FYI - Typst will sell you a self-hostable version of the webapp.


With any new DateTime object in any language I usually look at its persistent fields to judge what the memory and access characteristics are.

In case of Temporal it looks like that Chrome goes the JavaScript Date way as it only holds the timestamp:

extern class JSTemporalInstant extends JSObject { nanoseconds: BigInt; }

And then calendrical fields are computed on the fly. Is this correct?


Dropped into Gulf of Mexico. Response: Finding downstream path from Unknown Territory


I believe we call that the Gulf of Authority now.


The Gulf between the Two Ears.


It does that for all ocean.


You mean Danish Gulf?


Now we need a tutorial how to take the pedals off the bike. So you do not damage the crank because of the opposite threading left vs right.


My mom bent a lug wrench trying to change a flat on my grandmother's car; apparently the nuts were reverse threaded on one side of the car.


That is definitely something to watch out for with cars from the 50s to early 70s. Often the studs will just snap and not bend the wrench though, which is fine since it is better to just replace them with right hand threaded studs.

I believe the idea back in the day was so lug nuts would want to screw themselves tighter if they were loose whenever you braked as a safety feature so the wheels don't fall off. In practice it isn't really effective at unless you are doing some crazy hard braking like in a race but they should never be anywhere near loose enough to start with for such a minor force to screw or unscrew them. Your wheels aren't really suppose to be holding you up through the shear force across the studs, but held by the clamping force friction between the wheel and the wheel hub.


Back off

Tutorial complete. You just have to keep those two words in mind.


That terminology might not be clear to a non-expert.

If your wrench/spanner is pointed straight up to the sky like a clock hand at 12, rotate towards the back wheel to loosen, and towards the front wheel to tighten. Important! When you put the pedals back on and rotating toward the front wheel isn't working, you've grabbed the wrong pedal. Use the other one.


Surely, your claim would only apply to contracts or court decisions, but not to laws.


> has fallen by more than 97% per kilowatt-hour

So how much did it fall per MWh?


You're not going to believe this, but they have also fallen by 97% per MWh.


Unbelievably, it was also 97% by GWh!


Yes and no. On a spherical cow, units convert without cost. In the real world, someone ordering GW-hours of batteries is buying differently from someone buying W-hours. The prices of batteries at various scales have moved differently, with small batteries having become cheaper faster than big ones.


Even more: in the old days, any buyer slurping up production by the MWh would have noticeably tipped the balance of supply and demand.


By the pound, they’re 99.1% cheaper.


How much cheaper by the dollar, then?


Power is king for commercial batteries. On whole sale energy markets you often see high prices in one 1/4 hour, and much lower prices 1 hour later. You can than nicely make an arbitrage profit if you completely cycle the battery. Also many such batteries have similar Max energy and power limits, e.g. 1.5MWh energy vs 1MW power.
