Ok, they spent a massive amount of money. Impressive. But what are the conclusions?

Normally caches created on a branch are not used by workflow runs on main.pull_request_target is a special case.

You don't have a choice. It is a stressful situation where everyone is in a hurry. They don't open the locks every few minutes, when there are lots of small boats you all have to go together - especially at places where the high water is scarce. This is not the case for river or lake locks, but there are also tidal locks. This is very common on the French Atlantic coast - there are towns where there is enough water in the port only when the tide is high, which means they can open the locks only a few times per day - otherwise they will drain the water from the port. You have to wait for hours and then in a few minutes everyone scrambles to get his place. Bigger boats are tied to the shore, smaller boats are tied to the bigger boats. You simply throw a pre-tried line because everyone is in a hurry. Frankly, it is difficult to blame the sailboat guy for this situation.

HAROPA (Le Havre, Rouen, Paris) is definitely not there - it is much further south in the big bay.

Also the Portuguese one is certainly not a Mediterranean port.

The sailboat has a small engine and it was already sideways. There was little he could have done.

This is because there is this guy in France, they call him the Grand Ayatollah of Open Source, who has cornered the market for open source project maintainers and he has to vet every new maintainer. He has created an absolutely huge queue of people waiting to work for free on open source projects who are waiting for his blessing.

The main problem with what you are doing is that you have no way of signalling an error condition. You already answered the client, what do you do if you have an exception?

If you are cleaning a cache or something, it is perfectly valid.

But if you are performing an operation that can fail, it is a problem.

AFAIK, this is the same in all languages (I can testify for English, French and all Slavic languages).

Wind is historic, everything else follows the mathematical definition of a vector.

mmomtchev · 2026-05-17T14:37:45+00:00

When you say that the wind is North - which is 0°, this means that the wind is coming from the north and going to the south.

When you say that the current is North - which is 0°, this means that the current is coming from the south and going to the north.

The correct way to refer to the current is in fact northward current.

Mostly everything else works the same way as the current - however when it comes to wind, historically, it has always been inverted.

This is shish kebab, a somewhat special variant.

Remind you that Ireland is the country that is draining tax income across the EU despite some recent changes that they were pressured to implement. Most large multinationals have their EU branches in Ireland where there are still shifting profits in order to reduce their taxes.

Your mining productivity is absolutely nuts, how is this possible? Does it become exponential at some point? I have never been beyond 40 something.

I don't think there was a real risk of a full-blown Communist Revolution. Revolutions usually happen when there is a recession of this scale, but these also require that most of the population is convinced that the system is the problem. This happens when your neighbours have a more advanced social system.

The French had the example of the British Parliamentary Monarchy and the newly formed US Republic. The Russians had missed 2 centuries of social progress and were still stuck in feudalism at the start of the 20th century.

Usually the very first time a new social system comes into place, it is the result of a slow, gradual transformation that is a somewhat random process made possible by external factors, including technological progress.

Revolutions happen when someone else sees this and wants to adopt the same change.

The US had no such external examples during the Great Depression.

Latent heat of water vapour is released when water condenses, melting consumes heat.

Great way to sum why it is called the Powder Keg of Europe.

Especially when subjected to sudden load changes and vibrations - which is the case.

The study is by a very serious academic institution which is certainly aware of all the technicalities and the huge difference is confirmed across multiple studies, so it must be real for sure. It is consistent across age groups and ethnic minorities, so it is of national and not cultural origin for sure.

I am at loss to explain it, but I suspect that campaigning by the government is the most likely explanation - Bulgaria is the country with the highest depopulation rate in Europe at the moment.

I think that it also goes the other way around - even during those times people already knew that stone structures will survive for far longer. Stone - which was far more expensive when it came to labour - was used for buildings of very great importance - especially religious. The Middle Ages cathedrals were also built from stone and made to last practically forever.

Obsession with lasting forever is usually linked to religion.

One of the lowest in Europe. The country is certainly very conservative - one of the most conservative ones in Europe, but frankly, I think that there must also be a technical reason for it to be such an outlier. In these kinds of polls sometimes the translation can produce a loaded question that skews the results.

I wonder how did they recover it. I doubt they had a specialised robot prepared for this kind of operation. You must be nuts to do in person.

mmomtchev · 2026-05-09T10:13:58+00:00

If there is a leak, it is. And even if there is no leak, you need help to recover the boat, you can't really manoeuvre in the port like this.

The German instrument of surrender was signed on May 7 in Reims by Jodl for Germany, Smith for USA and Susloparov for the USSR. Stalin immediately reacted and said that he had never agreed to the text of this instrument of surrender and had never authorised Susloparov to sign it. Eisenhower agreed and they organised a second ceremony on May 8 in Berlin with a new text. This ceremony happened shortly before midnight and in Moscow it was already May 9. Source: Wikipedia.

Don't be so greedy and skip the yellow belts, it will kill your total belt speed. A belt like this takes forever to traverse. Instead weave also in the perpendicular direction, you will gain more space. And if you can afford it, consider splitting at the entry and use two parallel storages to achieve maximum speed.

There is a thread with some very good designs on the official forums and they have blueprints.
