The conjecture assumes durable goods, so it doesn't apply to medicine. Also no resale, so that narrows the scope even more.

The gist of the conjecture is that if the customers can wait out for price drops and the monopolist wants to sell their thing, then after a few rounds of "he knows that we know that..." the price ends up to be the marginal cost.

Now, real world disagrees with the model, so next steps are to examine why this happens and maybe discover some new economic interaction.

That's a bit unfair, since one of the achievements of Gustavus Adolphus was establishing governing institutions and professional bureucracy.

The bigger issue with that plan was be that the king was off fighting a war in Poland.

EU has Aisler but what you win in shipping times you lose in production lead time (unless you pay for faster service).

And there are probably others but with even less visibility / willingness to interact with private customers. Hell, I used to live next door to a sales office for a local PCB fab, but they never bothered to answer my inquiry about prototypes.

(That's another thing the proto-friendly companies do right: instant quotes without log-in requirement)

My personal experience is like getting eye glasses for your appetite. Easier to eat reasonably sized portions and they're nutritionally well-balanced.

Also the late night cravings are more specific: instead of vague "need to eat something", it's "I'd love a tomato" or "mmm yogurt" or "actually a load of carbs would hit the spot".

Got knee surgery with an epidural that leaked. The surgery itself went fine but the headache and nausea afterwards were absolutely brutal.

55 C might be enough to heat buildings but it's right on the edge where domestic hot water needs to be to kill Legionella. So traditional DH systems need to run hotter.

There low-temp/cold DH systems out there that rely on heatpumps in the buildings to extract the heat. Less losses in the network and you can even use them for cooling, but needs heat pumps everywhere.

In comparison, a traditional heat exhanger is pretty simple technology; just a hunk of metal with a valve.

Not yet, the Microsoft center is still in planning/construction.

But up north there's at least one city (Kajaani) on data center heat; details in another comment.

Nice!

Apparently the local supercomputer cluster in Kajaani has also been hooked up in 2021 and is responsible for a fifth of heating.

Microsoft's already building data centers hooked up to district heating (Espoo and Kirkkonummi, Finland). Heatpumps are amazing.

(Seasonal heat storage is also a thing, Espoo's neighbours have tens of GWh of storage, with a new 90 GWh cavern in the works. Not sure if the systems are interlinked.)

And then there are us engineers. I don't care much either way whether Maxwell's equations are ∇F = J or some other form, as long as it makes the problem easier to solve.

If I were in the GA Marketing Committee I'd publish a paper with suitably hand-picked worked examples where the vector approach is long and tedious, and GA version is short and sweet.

The electricity can flow both ways in a cable, and for example right now Denmark is exporting to most of its neighbours.

https://www.svk.se/om-kraftsystemet/kontrollrummet/ is a wonderful resource

They're not great for anything that might produce heat. Seeing a MOSFET slowly starting to imitate the Tower of Pisa after dissipating a measly 1 W for a few moments was a sight to behold.

For about two seconds before I cut the power.

Perhaps more inspired by the INTERCAL's PLEASE.

One of these years I'm going to make a Finnish programming language that enforces the correct case in arguments. And I don't mean silly arguments like camelCase vs kebab-case, I mean grammar.

Some examples to illustrate:

  tiedosto on "foo.txt" avattuna
  tulostin on PRN1
  kirjoita(tiedostoon, "a")
  kirjoita(tulostimelle, "b")

This is the kind of quality response that makes HN great.

Nah, it's pine.

Tar. Specifically wood tar,

If there were one. The closest thing is the Treaty of Lisbon, which in turn was an update on the Treaties of Maastricht and Rome.

However, the matter has been heard in the European Court of Justice in 2002, and the short version is "Community law does not preclude compulsory military service being reserved to men."

For more details, feel free to study the legal opinion behind the ruling: https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CEL...

Humbug. Defence policy, especially how the EU member states choose to organize their military forces, is very much in the hands of the individual countries. A majority of the member states don't even have conscription anymore.

Yes, there is the common security and defence policy, and the Article 42 of Lisbon and all that, but it all still relies on national systems.

Most of economics is educated guessing, and having more data (hopefully) leads to better guesses.

With this study there's plenty of leads to follow. Does the ABV have an impact? What about the base price? France vs Italy?

Goldman speaks of the current tariff regime; the study here looked at 2019-21 wine tariffs.

Also the tax burden will fall on different places depending on the markets and the good in question.

I couldn't let this be, so I went through the commits and as far as I can tell, that's the case. The committer/author names and timestamps are consistent with using --author on a commit (... or in a few cases, --amend --author).

Except one: commit 3d1fdddf9 has Jia Tan as both author and committer but the author timestamp is in +0300 while the commit timestamp is +0800.

UTC+2 isn't very convincing as an argument for Russia. Only the Kaliningrad exclave uses that timezone, and if I were in a state-backed group, I'd live in one of the big cities.

Also quick search suggested UTC+3 was seen during the summer, and Russia doesn't do DST either.

Edit: some of the UTC+2/3 times are attributable to being differences in git committer and author dates (e.g. email patches)

Way more than a foot, but that's the general idea.

There's a soil remediation project near my workplace (former railway depot). They've dug up several meters deep by now.

For most of Great Britain, the grid north differs from true north because the grid cells are fixed size, so they "fan out" compared to longitude lines. The exception is the 2°W meridian where the grid lines up.

The magnetic north wanders around, and it now happens to match along the 2° meridian.

But really the article is a year early, as the alignment point should make a brief landfall in Scotland late next year (which the article acknowledges later on). Or perhaps they expect Scotland to secede before that.

It's Juice (Jupiter Icy Moons Explorer) and it's not yet anywhere near Jupiter. Its trajectory has a few slingshot loops around Venus and Earth, and it's just coming off the Venus encounter.

It's about 0.43 AU from the comet at its nearest, whereas Earth will be pretty much on the opposite side of the Sun, making observations difficult from here.

Edit: Earth, Mars and Jupiter are in roughly 120 degrees from each other as seen from the Sun, with the Earth-Sun-Jupiter angle closing up fast and the E-S-M angle growing slightly slower. In about two months the E-S-M angle will be 180.

Wikipedia lists both "cat" and the Finnish "mäki" under æ: https://en.m.wikipedia.org/wiki/Near-open_front_unrounded_vo...

Do you have some example words that would show the difference?

Do you have any examples? As a Finnish speaker the Swedish "a" sounds the same. "Pappa", "framtiden" etc.

It's "ä" and "e" which have swapped uses, but it's not exactly consistent (e.g. "Järnvägstorget" where first ä is close to the Finnish ä, second ä is closer to e but so is the e at the end)

I took the electricity spot prices for the first three months of this year (so that it covers the cold period), and ran a simple simulation on it.

The simulation model assumes we're charging during the 12 cheapest hours, and discharging during the most expensive 12 h, and then calculated the average price differential per day. This is of course suboptimal, since the day-ahead prices are available.

The mean differential in the data is 56.5 €/MWh, and on 64% of the days the differential is over 22.8 €/MWh. 10%, 50% and 90% percentiles are 3, 54 and 119.

So at least during the winter time (when consumption is greatest) you'd expect to hit the price goal more often than not.

Adding the rest of the year up to now drops the mean to 52 €/MWh and the median down to 38 €/MWh. Still pretty good.

(As for cherry-picking the data: this year was easily available and didn't dig too hard for older data, but it was one of the mildest winters in recent years.)
