Comment Selection Bias, Safety Net (Score 1) 70

Is this actually true?

I suspect it may be true if you look at the very high profile, top of the pile. However, these are clearly the exceptions and not the rule. How many people went to university only to drop out and found a company that failed or at least did not do anything like as well as Apple, Microsoft etc.? We do not know because nobody has ever heard of these people unless they failed spectacularly like Elizabeth Holmes.

I'd look at university (rather than college) as career insurance. Get a good degree in a useful discipline and you have a safety net that will make it much easier to get a decent job. Once you have that, go and follow any crazy, speculative ideas you may have to see if you can make them work. If you can then that's great and, if not, you have your degree as a safety net to fall back on to get a decent job.

Comment Re:Poor Boeing. (Score 1) 35

Hell, everything about that plane is really fucking nice.

Except for the windows that are entirely under the control of the cabin crew who will decide when you are allowed, or not allowed, to look out of them. If they would replace them with mechanical blinds or remove the ability for the cabin crew to be able to force them to go opaque I'd agree with you.

Yes, but if it were cost effective and reasonable you'd see SpaceX doing both research and lobbying efforts to allow private sector organizations like themselves to do this.

I agree, my point is that the reason it is neither reasonable nor cost effective is because of the huge dangers around launching large amounts of fissionable material to orbit. The technology is actually relatively simple and cheap, at least compared to a chemical rocket, and the cost of the fuel is also not an issue. The problem is getting the fuel to orbit without a risk of causing widespread nuclear contamination.

the entire space industry is now being driven by the private commercial sector, which is incredibly risk and cost adverse

The private sector may be more cost-adverse but it is far less risk-adverse. There is no way a government program would have been allowed to have as many failures as we've seen with Space-X's Spaceship.

The reason nuclear propulsion has not been adopted is because of the huge risks in launching large amounts of fissionable material to orbit. Even far smaller radio-thermal power generators (RTG), such as those used by the Cassini and Galileo missions, lead to significant precautions during launch. A nuclear rocket will require orders of magnitude more fissionable material than an RTG.

Comment Launching Nuclear Material (Score 5, Insightful) 47

Nuclear rockets are nothing new but the reason they have not seen significant use is because first you have to launch them to orbit. Rockets have a not-insignificant chance of exploding or crashing during launch and when you have them loaded with lots of fissionable material the effect is like a dirty bomb that has a good chance of scattering highly toxic, radioactive debris over a large area.

I suspect we will not see nuclear rockets until we develop a fusion-based one because, unlike fission-based designs fusion uses light, non-toxic, stable isotopes as fuel and so is likely to be no more dangerous than current chemical rockets.

Yes, it does not seem to be written in the rules but it is what the driving instructors taught my kids and what they are tested on. I also got told that when I had to do a driver safety course for work! It is also what most people seem to do since, when I first arrived in Alberta I almost got into a few accidents entering roundabouts because someone indicating right actually wanted to turn left and exit! I now basically ignore indicators on Alberta roundabouts because they provide zero information about what the driver is about to do.

Comment Worrying Signs (Score 1) 23

So now we have AI writing a report to allow it to grow and spread further. Isn't that a key sign of life...either that or it's a sign of incredibly lazy civil servants. The irony will be that in a few years they'll be the same people complaining that the government is replacing their jobs with AI.

Comment Nothing New (Score 1) 34

The level of trust that some people place in today's AI systems is just bonkers.

Blindly trusting technology is nothing new. Back when GPS navigation was relatively new there was a place up in the Yorkshire Dales, appropriately called Crackpot, where some devices would suggest cars leave the road and drive down a muddy cart track to the river Swale, drive through the river and up a track on the other side. The number of utter idiots who blindly followed those directions even though they could presumably see exactly where they were going was phenomenal. There was even an article on it in Slashdot.

If people are quite literally willing to drive off a (small) cliff into a river it's hardly surprising that they trust AI.

The difficulty of obtaining a American driver's licensure varies literally from city to city

My experience getting a US driving licence near Chicago was an eye opener in that regard. First they suspected that I'd used their highway code book during the theory test because I got all the questions correct and then I thought I'd failed the driving test because the examiner have be drive around the block meaning that the most challenging part of the test was making a left turn back into the car park making me think that she'd cut the test short because I'd done something to fail it!

The even more amazing thing was that there was some big scandal at the time about people paying to get a licence without having taken the test which had me wondering exactly how bad a driver you had to be if needed to bribe someone because you could not drive around a block!

Comment UK Limits were Higher, Now Comparable (Score 1) 181

Please correct me if I'm wrong here Slashdot Brits with American driving experience but British speed limits are generally lower than ours

US speed limits annoyed the heck out of me when I lived there a few decades ago because they were so much lower than the UK's even when driving through the middle of nowhere without any traffic. The UK has a 70mph limit on motorways and 60mph limit on single carriageways away from towns and villages. Other than Montana, it is only recently that the US seems to have largely increased limits to the UK's or, in the west, even surpassed it slightly. Even when the limits are similar or higher in the US, every time you get near any town or city the limits drop and that's a lot rarer to see on UK motorways.

However, while the UK's speed limits were/are a bit higher than the US's you often can't drive at that speed due to the huge volume of traffic. The slow down that this causes also decreases road deaths which I suspect is a big part of how the UK's roads are safer.

They may save lives

They may save lives in the UK but here in Canada the rules for roundabouts are lethal. Instead of the UK rules where, on approach, you use your indicator as if you were approaching a cross-roads, here in Canada you are always supposed to indicate left when entering the roundabout even when going straight ahead. This means that when you are waiting to enter the roundabout to turn and see a car approaching that it indicating that it is turning left to stay on the roundabout - meaning that it is safe for you to enter - it might actually mean it is intending to turn right and leave across your lane in which case it is unsafe for you to enter.

I do not know which idiot came up with the Canadian rules that have you indicating left just before you turn right to exit but I think they should be sentenced to live in Milton Keynes for an extended period to get some practical training.
