> From swimming lessons to recreational use and high-level competitions, the Aquatics Centre will be multifunctional. From July 2025, the Aquatics Centre will become a vast multi-sports facility open to all, including two pools (50m and 25m), a fitness area, bouldering area, paddle tennis section and pitches for team sports. It will also have an adjustable floor to serve a variety of purposes (swimming lessons for babies and children, etc.). The Aquatics Centre will also be the state-of-the-art facility that the French swimming community has been looking forward to for decades. The French Swimming Federation will be able to host national and international competitions in its four indoor disciplines. The Centre will also provide a best-in-class federal training facility for leading French athletes and will notably be home to the country’s diving centre


You don't need a 150 million Euro facility to teach swim lessons and recreational uses. As far as high level competitions...

>This capacity, which may be overlooked by many, is not for World Aquatics, which requires a minimum of 15,000 for top-level swimming events, so France will not be able to host a World Championships


Here's the full preliminary incident report if anyone wants to read it:

https://publicapps.caa.co.uk/docs/33/NERL%20Major%20Incident...

Obviously concerning that a single (perfectly valid) flight plan can take down both the primary and backup. Reject the flight plan that the system can't understand, you've got 4 hours for someone on front-line support to be able to work out the correct path and enter it manually? Meanwhile it'd be good if the system continued to operate.

Futher concerns about first and second line support being unable to find in the logs the cause or even the flight plan being processed when the systems failed. Had to bring in the 3rd party developers to look at "lower-level" logs to find out what happened. If your monitoring/logging isn't good enough that the first responder can't work out at least what the system was doing when it failed, that's a significant problem.


Most of the system did continue to operate - but it couldn't accept new flightplans automatically; the flight plans were given 4 hours in advance, so they only put in the restrictions after a couple of hours. Still I agree it would have been better if it had continued - but yes the most important bit is how long it took to find the bad plan.


Yep. From the report: At 0832 both systems failed and the controllers started to empty the four-hour buffer. At 1100, systems still weren't back and so to avoid the hard cutover that looked to be coming at at 1230, they began the switch to manual mode. It took them until 1336 to restore the automatic systems, and until 1803 to fully switch out of manual mode.

Given those operational constraints, it sounds like the support teams basically have two hours to resolve a critical system failure.


For more context on how big a deal this is, the A220 is quite widely seen as the future of short-haul aviation. Airlines are moving towards a point-to-point model instead of hub & spoke (especially in Europe), using smaller planes with lower capacity, but flying more frequently, together with best in class fuel efficiency (with the price of jet fuel only really going to go in one direction in the next decades) means the 220 is very, very popular. Airbus is expecting to sell 7,000 of them in the next 20 years. That's coming close to the incredibly successful A320 family (including A318, A319, A320 and A321 models) which has sold just over 10,000 planes since 1986.


Archive.org was knocked offline the other day due to some AI startup scraping it to death. It’s not a good thing.


Source, they don’t rate limit



True - and their lack of rate limiting ended up letting someone overwhelm their servers, knocking them offline.


They put out a blog asking people not to scrape afterwards. A simple google will be much fast than asking for sources.


It claims it will use rotating detonation engines, which are currently at a NASA tech demo stage. At best. They're super complex, currently not very stable. It's long, long way from becoming stable & reliable enough to be used as plane engines or being commercially available. The current record is 10 minutes firing.

My favourite thing about the Emailer is it was often stylised E-m@iler, which is the most incredibly 2000s branding.


Restless Leg Syndrome is absolute hell. Combined with insomnia it's nearly killed me a few times. I think a lot of people (including many doctors I've dealt with) underestimate it due to it's rather benign sounding name.


Did you ever share that paper publicly? I'd be interested in reading it


"Musk has reportedly told engineers to have the project completed by November 7 or else they'll be fired"

Wow.


Strongly agree with what you're saying. I think they've brought out a good game with a solid foundation for turning it into a great game with tweaks and expansions. I've put 26 hours into it since Tuesday and I'm loving it, so they've definitely done something right.

Agree with the tech tree, it's too short and you likely won't vary in the techs you get if you're playing a country with reasonable research points. I'd love some more country-specific flavour and actions; I understand folks don't want to be railroaded (having options to play a country any way you want is great), but it feels a little empty at the moment. Of course this can be modded in and filled out with DLC down the road.

If you enjoy this era of history or enjoy other Paradox games, I'd strongly recommend giving it a go.
