That could very well be the case. I can't be certain. However, it's also a well-known problem in engine design. High flow rate fluid lines like propellant lines are often protected against fluid hammers. That may come in the form of a gas reservoir to absorb the pressure spike (sort of like surge suppression capacitors in electronic circuits) or as a check valve connected to a re-circulation path (like snubber/flyback diodes in electronic circuits).
The reason why I said it sounds counterintuitive is that I suspect that the flame extinction inside the combustion chamber also causes strong mechanical shocks. However, I don't know how that works and I could be mistaken.
There will be a concert for 750th anniversary of Amsterdam in June (held on the highway ring around the town which will be closed). Tickets were free, sold out in 5 mins, immediately available from scalpers for 200 euros.
Well yes, the concert is funded by city, and they wanted everyone to have a chance at attending, no matter what their income was. Not everything needs to be sold.
The problem there was not having enough security - it's like store giving out free popcorn, and someone comes and steals the whole cart. In the physical world, there would be someone standing next to the cart watching that people take reasonable amounts. In the digital world, nothing was done, so thieves stole a lot.
Not sure what the best solution was to be there... I like the idea of giving people few days to sign up, then randomly choosing who gets to go. Of course this has its own problems - for example you want to allow groups, but this can be abused. Identity verification helps with that, but this makes ticket checking much slower....
It's NL and the everyone has a personal id. There is a national service to validate that, too.
One week accepting of requests - a person can submit multiple id (incl. children). At the end of the period a random lottery with some bias to people registered in the city (in the end the event is paid by them)
I once trained for a mountain hike by walking up down the stairs in our 14 floor apartment building with 25kg backpack. I had no idea it has a name! I also walked 15km to work a few times, but I admit it affected my productivity...
The data I can find doesn't support the assertion.
> In the period between 2019 and 2022, 1,199 cyclists were killed in traffic accidents, with 42 percent of these accidents being caused by collisions with a passenger car or van.
Here is says that indeed cbs doesn't track it and that there were 21 deaths per year caused by trams, buses and trains, with 57% of those pedestrian or cyclist
this ad-article "Jaarlijks worden er om en nabij 150 personen behandeld in een ziekenhuis na een aanrijding met een tram en komen er zelfs 40 personen te overlijden na een tramongeval." - I think what they mean is 40 people in a decade?
Really nice article, thanks for sharing. With digital pathology ai startups going bust left and right it's quite an accurate analysis. One thing it's missing in the "product" path is preanalytical differences - same tissue processed in different labs can produce wildly different pixels.
I think in normal colonization the king just funded the army from the taxes you paid. So, the more goods you sold him the bigger the army. If you traded with the natives instead it wouldn't grow as fast.
