Meh. When I was an undergrad, you really needed to understand netmasks if you wanted to set up a network for multiplayer games. Now, it's much easier (although Windows makes it stupidly hard to create an ad-hoc WiFi network. No idea how people think it's ready for the desktop), and you can do a lot without caring. I can't remember the last time I needed to know about them.

The USA built a working molten-salt reactor, which Nixon ordered abandoned because it wasn't useful for plutonium production.

the temperatures, pressures and the levels of radiation that occur in those designs.

It sounds like you're not at all familiar with the design that Sorensen is talking about. It operates at one atmosphere.

The market not IETF process decides which protocols will continue to be used going forward.

The market loves when we have formal documents laid down by the Formal Documents People confirming what we've been telling our bosses for years. I would bet large sums of money that some tech, somewhere, just walked out of a meeting happy because he finally has permission to deprecate a long-broken system.

I live in the middle of nowhere so I can get away with it to some extent but I still am much more attentive and even tend to change my driving position before doing so.

that's why these cars have three or four seating positions, right? One for me, one more for me, and if there's any left then maybe I'll let someone else have one... but I'm going to also need a backup of my primary settings in case someone craps on them

Even the multi-function displays in the middle of the instrument panels on *all* cars made in the last three or four years is too much.

The MFD in the middle of my 1997 Audi A8 (from which all other MFDs today are descended, it seems... esp. in VAG-land) is no more distracting than the MFD which was in the middle of my 1980 280ZX, but it's actually useful because it does more than just show me system status during the POST. It then provides the trip computer. If I had infotainment then it would show me tracks. If I used FM it would show me radio stations. But since I don't do either it only shows me driving-related information; MPG and the like.

I only find the center MFD design to be stupid for sports cars. The tacho belongs there, damn it! But they could still have a MFD off to the side opposite the speedo.

I hate dial meters. I wish they'd die a horrible, gruesome death.

That's because you're not a driver. You're a passenger behind the wheel. If you were a driver, you'd like dials. Maybe not so much for the speedo; you don't need to see how fast you're going faster than you can read a number. But in a driver's car, the front-and-center-mounted tachometer needle is absolutely critical. You can't function without it.

With that said, I like the idea of self-driving cars, and of being able to be a passenger myself. But as long as I'm driving, I like to really drive. Also, note that I have literally never owned a vehicle with a center-mounted tach. I did get a gauge cluster with that for my 240SX, but I never got the cabling to install it and then I sold the car. Still have the cluster, want to use it with my PC for racing sims. Sooner or later I'll figure out how to drive it, I have too many projects already. I've ticked off some minor ones recently, though, so there's hope.

The color bar tachs take up too much space. If you make them big enough to have any resolution worth mentioning, they are massive. That is stupid. One good-sized dial tach and a medium-sized digital speed off to the left of it is my ideal layout, obviously with oil pressure, water temperature, and a real live voltage gauge next to it, plus boost when applicable. That tells me everything I need to know, and right now.

A Nintendo-style controller would suit me fine.

No, no it would not. Nintendo games don't model the road. If you tried it, you would be very sad very quickly.

There is debate with chemical fact?

Facts are useless if you don't comprehend their relevance. While you drive down the road, it's normal for your night vision to be impaired anyway due to reflections, oncoming traffic, stationary light sources...

That is not up for debate; it is simple and pure chemistry.

The world is neither simple nor pure. If you wanted simplicity and purity, you should have become a theoretical mathematician. Applied arts feature complexities.

In the UK, you can be fined huge amounts of money for a small excess of speed, so speed is important.

I like HUD, but I think that GPS-enabled cruise control (with camera backup) is the best way to handle avoiding excessive speed with technology. The hardware for that is in most cars now.

The question is, is it better than people at spotting small children running out from behind stationary buses?

That actually seems like a pretty easy thing for a computer to handle detecting, so the answer is probably yes. A lot of cars will now not only detect that but actually brake for you.

My car has the speedometer right below the windscreen, in the driver's eyeline when looking forwards.

You mean front, top and center? Well, that's just bad design, right there. There should be a tachometer there.

With the police using dodgy equipment and the proliferation of cameras you become obsessed with making sure I'm never even 1MPH over the limit

Blaming your speedometer for bad ticketing practices is like blaming cotton for slaves getting whipped.

Obsession with speed and limits makes the roads less safe.

That doesn't really reflect on the validity of the idea of a HUD, though.

but if they wanted to, they could require reviewers to "check in" at the business (using GPS locating to ensure the customer was actually at the business)


The right way to do it is reputation. Reviews on TripAdvisor are generally ignored if they are not attached to a human with good reputation. Nothing else matters but the web of trust. It's difficult and time-consuming to fake enough content to get a whole bunch of accounts good fake rep in such a system.

My experience is that people who show up for a product or service (or pizza, whatever), get what they ordered and are content ... do NOT generally stop what they're doing to run off and tell the world, "My $10 pizza was satisfactory." Anybody who has ever worked retail (and paid attention) can tell you that a hundred happy customers will simply return for more business when they want, but not take time out to communicate to the business or to anyone else that they're happy customers. Life's too short, they just carry on. People who are truly dismayed about their experience, however, will take to every communication method they can dream up to make sure the world knows of their displeasure. And some of the people who do that are just plain nuts, or have very poor judgement, or are either hobby-level or professional trolls. That's who we all hear from, well out of proportion to the real-world experiences of most people. And the internet echo-chamber tends to greatly amplify that effect.

If you can't learn to do it well, learn to enjoy doing it badly.
