Arduino is very "light-duty" - this summer's best Arduino board had an 32-bit ARM processor at some 80 MHz, with 512 kB of flash and 96KB of RAM. Meanwhile, the Raspberry PI runs at about 1GHz, has 512 MB of RAM. Meanwhile, an x86 (64 bits) processor runs 4 or more cores at 3+ GHz and can access 16+ GB of RAM.
None of it is "better" than the other, they're just optimal for different tasks - Arduino for easy hardware work, prototyping and very low power, Raspberry PI for more processing power at a low price, and so on. Just like some people need a semi and some need an ultracompact car
"the availability of that process was predicted by Moore's Law"
The Moore's Law apply only retroactively. This being said, while transistor density might not improve according to Moore's Law, usually you have increases in one or more of the main metrics (power density, switching speed, leaked power, works on lower voltage,...) and can compensate for some others in hardware (multiple power planes, wider buses, more execution units, higher speed on the same basic architecture, lower power on the same architecture,...).
And, if you're an important foundry partner, you know about the foundry's plans - and can design something for the manufacturing capabilities of next year. On a two years, it's somewhat of a gamble, as you don't really know which advance will come next - or should I say which will be production-ready by then. If your target is a specific quarter, you might miss your shot due to lower-than-expected yields for example (or higher-than-expected yields coming a quarter or two before your design is fully ready). This yields improvement business is mostly trial-and-error stuff, and sometimes yields decrease until the cause is found and repaired.
There is enough "excess void" in the brake booster to safely use the brake (full depression) twice (maybe more). On an '92 Passat it was about four "halfway brake pedal press" (decent enough braking) until the pedal became very heavy. On a 2000 Astra it's about twice half presses with engine just stopped.
Three times the mass won't help you at all if you hit a concrete bridgepost. And will make only a 5% or so difference if you hit a loaded semi. My '92 Passat was better in many ways than my 2000 Astra G - but safety most certainly wasn't one of those.
If you change wheel sizes, then you should be able to adjust the reading. External circumference of allowed wheel sizes for a certain vehicle can vary quite a bit, if I remember correctly.
I've just checked, and for Opel Astra G legal tire circumference varies beetween 72.5 inches (165/70 R14) and 78.1 inches (205/55R16), a 7% difference. One might want to use a type of tire for summer and another for winter (for example). While lower/higher indicated speed wouldn't be such a problem, maybe the fuel efficiency "hit" shown on the trip monitor might be a different thing.
Just as Elon Musk said, to put a pound of payload into orbit you use about the same fuel as to fly that payload around the globe. The difference is in the costs of the plane versus costs of the rockets.
It goes to space based on the current understanding of the atmosphere highest limit (above that is space). The edge of space is conventionally at 100 km (or 62 miles).
It is true, the velocity of the Space Ship 2 at that altitude is negligible - and it would need some 6+ km/s (I think), or more than four miles a second to stay in orbit.
So, in the end, it's just a novelty thing. Just like the first flights of the Wright brothers (and other pioneers in aviation) were tens of feets (and altitudes reached were in the tens of inches), figuratively landing in the same place where their flight started
Frankly, there was a time when motherboard reviews from Anandtech presented the number of times the board crashed during testing. It then went lower and lower, then they only crashed when using interleaved memory banks, then they didn't crash at all during normal use.
Or maybe the crashes weren't reported any longer.
Not to mention power needed. What use is a human powered airplane that needs the power level of an athlete, while it would expect a small total load? What do you do against a front wind? While winds of 25 km/h are not common, winds of 12 km/h are quite common (and would double your flight time when going against them).
Also, this airplane seems to use more parking space than a couple of cars
Maybe because it was an university project? Plenty less interesting things were done as university projects.
What I don't like is that, while presented as an "flapping wing aircraft", this seems a fixed wing aircraft with a "flapping propeller" instead of a rotating one.
There is the issue of the car in front not braking, but catastrophically stopping (hitting a downed tree, or a stopped truck, or something). That makes you unable to stop if your speed is high enough, even if you're 6 seconds behind him (which, at 60 mph is about 500 feet - or 100 km/h and 160 meters)
Intel has enough money to buy AMD several times over - but buying something like nVidia (or AMD, or VIA for that matter) might be veto-ed by the Federal Trade Comission (for anti competitive reasons)
As for the murder of Nazi soldiers, French partisans were following the orders of the French government in exile. If they would have been captured by the French government of the "non-occupied" France (for as long as it existed as a client state to Germany), they would have been either extradited to Germans or tried (and most probably executed)
The U-Boats (for most of the war) were under orders to report contacts (via Enigma machines). Doubts about broken encryption would have been enough to put them into "communicate only if attack is impossible" - which would have been a huge problem, considering there weren't enough patrols to cover everything.
Also, the magic bar performance is very susceptible to hard drive slow downs (address bar takes forever to suggest history/bookmarks/... when a virus scan is in progress). Time to load might be long, but I only start Firefox once a day, so I don't really care.

Apple's retina at 2880 by 1800 is 1440x900 quad - and 1440x900 is a the resolution for 19" or so widescreen displays

My router has USB port but only for USB storage (for torrents), no printers.
This is not a couple of hours suborbital flight, this would probably take most of one day (or maybe more). And while it might be nice, it isn't space
There are reasons to fly "more than half way" - in air refuelling assets, staying close to airports and so on.
Just as Elon Musk said, to put a pound of payload into orbit you use about the same fuel as to fly that payload around the globe. The difference is in the costs of the plane versus costs of the rockets.

The American Fifth Amendment you say? Why would the UK care about that, when it's an issue between a British citizen living in UK, and the UK police?

Tell that to the first world war, second world war, famines, plagues, mongols and so on.

What happens when someone that attacks a soldier looks just like a civilian? If I'm attacking a military base does that make me a soldier?
This was great, thank you. I haven't tried it with a virus search on, but it certainly seem much faster
Thanks
