I was at Bletchley Park a couple of months ago and by chance the National Museum of Computing was open that day. They've got some interesting displays of old computers, and their goal is to get them all running again. They cover everything between EDSAC and modern computers. Their oldest computer is a Harwell WITCH from 1951 (a decimal computer), this is being restored at the moment. Other fun stuff includes a collection of calculators, and a BBC micro with a working BBC Domesday Project laserdisc installation.
It's a separate museum on the Bletchley Park grounds, and its opening times are a bit limited (esp. in winter), so check before you go.
When volume is ramped up, these could easily become less expensive than bifocals; after all, there's only one grinding operation per lens instead of two.
Switching manually is a pain, but so is moving your head to get the correct lens in view.
Sure, runways are numbered according to their compass heading, but the omission of the last digit tells me that it doesn't need to be all that accurate. That makes it unlikely that this number is used in navigation.
I'm no pilot, but the only actual function of the runway number I can think of is the visual identification (to make sure the pilot is lining up on the correct runway). What would go wrong if Tampa just kept using the number 18R/36L?
You liked that it was possible at all, probably saving you lengthy roadtrips to administer a remote server. But when comparing to working on a local machine, GP is entirely correct. I occasionally use a remote Windows computer. Even on our 100 Mbps company network the mouse lag is annoyingly noticeable, let alone when I'm logging in from home via an SDSL line (6 Mbps?).
Not really. As companies like SpaceX have shown, these days it's more rocket engineering than science. The basic principles are well known, the biggest hurdle seems to be quality control on a huge number of parts.
Also, the Kriegsmarine did not use Enigma machines for military communications.

Everything I've read suggests that the Kriegsmarine did use Enigma for military communications. They did have their own upgraded design (4-rotor) which was designed to be backwards compatible with army and government Enigma systems. This introduced a couple of weaknesses into the design (the fourth rotor didn't rotate, for example).
Not that old saw again. This program would allow countries to run nuclear power plants without having to develop a hugely expensive supporting industry. The same way African countries currently import cars rather than having to develop a car industry from scratch. It's just another way of bootstrapping the economy.
TFA implies that nuclear fuel costs ~ $2 million/ton. And that 80 tons is needed 'to refuel one reactor'. Both seem awfully high to me. I always thought a reactor contained a few tons of Uranium at most.
They did this before: the Napier Deltic was a two-stroke opposed-piston diesel. The Deltic was meant for use in small, fast ships and trains, and it had three sets of cylinders in a triangle shape, with a crankshaft at each apex. Thanks to its construction it had a high power-to-weight ratio. I haven't been able to find fuel consumption figures for this engine, though.
Still, there was a massive cost to the German reunification, see e.g. this article. The Bundesrepublik spent DM 1 trillion on this over the first 10 years. 20 years after reunification, eastern Germany is still struggling.
And that's with a society that was functioning reasonably before. North Korea won't be a market worth operating in for years because nobody can afford anything. There aren't many assets worth selling or investing in either.
What about novice or occasional programmers? I've done a few things in Python over the years, and I've found that even with this fairly simple language, my knowledge of the syntax etc. leaks away with disuse. I recently had to write a program after about 1 year of not using Python, and I spent half the time relearning the language. Terse, non-English languages like C have a higher barrier to entry than Python because of this.
The original announcement says nothing about DRM. Nor do I recall reading anywhere else about Apple requiring DRM be included in products sold via the App Store. To me this looks like the FSF is hijacking the issue of GPL vs. Apple license.
According to this, fast charging increases the rate at which dendrites are formed. A 6-min charge cycle would severely limit battery lifetime. I'm not looking forward to replacing 300 kg of batteries every year.
According to this, the faster you charge a li-ion battery, the more dendrite growth you get. So you're looking at replacing the battery rather soon with these 6-minute recharge cycles.
Which morons decided to pull this crap again, mere months after the last debacle? I, for one will NOT buy into wireless video until one of these technologies is safely in the grave.
There are cases where you would downsample. Eg when displaying a nice high-res photo.
Your idea has merit for drawing the UI, fonts and other vector data, but I just can't see it working with high-res pixel originals.
Also, I doubt vectorizing a pixel image will result in usably less data. If vectorization were a useful compression algorithm, we'd see it used in photo and video compression schemes.
What happens when the temperature increase melts the permafrost? ISTR reading that in region where this happens, solid ground turns into an impenetrable bog, so you may end up with a warmer climate but less usable ground.
(the silver lining here would be that hovercraft would become very popular).
If you can come up with an algorithm to select which processes should have the highest and lowest priority, you can write-up a tiny program that will automatically do the nice/ionice thing for you.
How about this: whatever I'm working on at that moment (i.e. the program in the foreground) must have the highest priority. I'll leave writing the tiny program as an exercise for the reader.
I'd also like to point out that Linux does it as well as any other OS out there
Does it? I have noticed IO-related slowdowns in Windows (often related to overzealous antivirus programs), but I can't remember the last time this was an issue on Mac OS. I recently had 5 copy actions totaling 25 GB running at the same time, and was able to continue working normally the entire time. I've no experience with Linux, though, so I can't compare directly.
Yup. That's because diesels lack a throttle valve. In a gas engine, the throttle valve increases the resistance in the intake system at partial throttle openings.
Some modern gas engines, e.g. BMW do without a throttle valve to mitigate these losses. Still, they vary the intake valve opening to modulate engine power, so there still are losses at lower throttle settings.

3D CAD. My colleagues regularly run into RAM limits with 4 GB.
It is Rocket Science.

Reversing changes to the body is all well and good, but will the newly-unaged mice still yell at the youngsters to get off their lawn?
The study looked at the 55+ age group only. I suspect people with serious health issues and no insurance will have died before reaching 55.
Eric: "Gee, Sergey, what do you want to do tonight?"
Sergey: "The same thing we do every night, Eric--try to take over the world!"

Using your figure of 1.3 kW/m2 for insolation, I get 1.3 GW/km2, ie insolation is 1/100 of your proposed 100 GW/km2.

So you would downsample high-res pixel images and send one vector per block? That would defeat the whole point of having a high-res display.
