This page was interresting and demonstrates some problems with CIELabls hue perception: https://raphlinus.github.io/color/2021/01/18/oklab-critique....


No not really. You need an explosion or energetic impact to trigger it, and potentially a fire too. But it might become unstable by heat and more so if it's contaminated by oil.

One early industrial disaster and the biggest explosion of it's time happened because the workers in a production plant in Germany regularly used Dynamite to clear out stuck ammonium nitrate in silos. The last time they tried, the plant was obliterated together with most of the nearby town.


I had to find more details. From https://en.m.wikipedia.org/wiki/Oppau_explosion

> Indeed, nothing extraordinary had happened during an estimated 20,000 firings, until the fateful explosion on September 21 [1921].


Nice.

I enjoyed this:

Maybe not as nice visuals, but it emulates the Original Spectrum port but transplants it in a VR capable renderer and adds David Whittakers Amiga soundtrack.

Interestingly, the game mechanics is as if it was made for VR.


The mechanics are basic enough that it's even suitable for Google Cardboard - VR via a smartphone!

No linux version though.

This one works perfectly on linux.


My only problem with this (and every other) game on Linux is that it always, always wants to start on my portrait screen, which invariably screws things up. It never starts on my landscape screen, even if that's set as primary.

I don't know how to make games start on a specific screen by default, I wish games had more options for this.


That sounds more like a window manager problem than anything else.

This is even less complicated than an adaptive cruise control system. If you point it to in the general direction of a mountain, it very much depends on luck if the descent is possible or not.


Terrain-following is significantly more complex than the most basic forms of adaptive cruse control. Radar works much better for tracking discrete objects moving at different speeds than mapping 3d terrain. This is why adaptive cruse control will often hit stationary objects and generally disengage at low speeds.

Remember, the aircraft needs to avoid everything in a line in front of it. But, they also want to stay as low as possible to avoid enemy radar, so it also wants steer steer around hills and even trees vs simply going up.


That's bullshit. What could we do? No political party were seriously against it, and it's not a huge question to form a new political party around.

They did a 'trial run' after the investment which I guess was to make it look more democratic, and there was a public referendum which I actually believe was not in favor, but ignored. (Or was it in favor by only the 20% living inside the toll gates where allowed to vote, and the surrounding 14 regions arranged their own ignored referendums.

They spent a bizarre amount on implementing this, basically paying IBM the complete development cost for a plate reading system but gained no ownership rights into the product, simultaneously implemented a radio based system that was later ditched, hired hundreds if not thousands of people working with the billing and help desks (so how automatic was it), and campaigning on how good this is for the society.

The cost for adding 20 something camera based toll gates were almost half of the cost of building a 5 km long tunnel that was finished a few years before and constitutes about a quarter of an incomplete ring road. 3 billion SEK compared to 6 billion SEK. ($340m vs 680m)

The incomes did not cover the running costs the first years and I can't find any facts on if it's actually covering it's amortized costs now.

Coincidentally, a similarly unloved project in Gothenburg to build a relatively unnecessary train tunnel to huge costs DID actually spawn a new political party that gained 20% of the votes. Maybe there's hope.


They don't move that fast, so saving space is more important. Not perhaps at the stations but at rail yards and transfers that might be underground.


In the UK most trains are fairly flat faced, however trains travel relatively slowly (compared to Europe) at a typical maximum of 100mph.

https://en.m.wikipedia.org/wiki/British_Rail_Class_450


That's essentially a local or regional train. Attaching multiple trains together and still allowing people to walk through is important.

Many local trains in Europe have a similar design, and a similar top speed.

The long distance trains in the UK do go faster and have an angled front.

It's presumable a trade off between aerodynamics and walk-through ability when connecting trains.


This specific configuration is for a commuter train, but similar trains (which can be coupled to other sets) are used on long distance routes in the UK.

As I said, the UK isn't really high speed compared to Europe. Other than the Eurostar line/HS1, all other lines throughout the UK are limited to 140mph (225km/h) or less.


I think an escape path in tight tunnels is the main concern for this design in the UK...


The procedure is to slam the emergency brake, then run as hell, as far back as you can get.


There's no limit that I know of.


No, you are correct, there's no limit.


Russian trolls and their "useful idiots" agree. That's about it.


Saudi Arabia is the ISIS that made it so I don't see your point? The beheaded even less so.
