2) A better engineered device is capable of doing a better job. It costs me pennies to get a low-power sensor with precision of 1/16 C. That's bags of headroom.

Could you point me to one? Last time I was looking for them, they all seemed terribly inaccurate (errors of 1 - 2 degrees Celsius IIRC).

I wouldn't even call Java object oriented, rather class oriented. It forces you to put everything in a class. Most of the time when I see Java code, there's a whole bunch of classes with nothing but static functions in them.

Python is in a sense much more object oriented than Java: everything is an object. Modules are objects, functions are objects, classes are objects.

40 mph is not exactly easy.

Even professional road bicycle racers reach such speeds only on downhills or in sprints; see e.g. "Individual riders can approach speeds of 110 km/h (68 mph) while descending winding mountain roads and may reach 60â"80 km/h (37â"50 mph) level speeds during the final sprint to the finish line."

40 mph is *fast* on a non-recumbent bicycle. The fastest I personally can do on level road without other traffic is about 50 kph, for maybe ten seconds. That's only 31 mph. With a not-too-bad racing bicycle and a reasonable fitness level. 40 mph (about 64 kph!) is for most people totally out of the question.

But the system should make an exception when it senses that there is someone in the passenger seat.

My previous car dissallowed control of the navigation system while driving, even when there was someone in the passenger seat who was perfectly able to safely control the navigation system. Very frustrating at times.

There is no unit 'degree Celsius'. Just like with Kelvin the official unit is without 'degree'!

Do you have a citation for that? Wikipedia [] seems to disagree.

I agree that much of this is academic and not relevant in everyday speech. But I think even there you are wrong: according to your previous post the "degree" part is optional, but in everyday speech it's the "Celsius" part that's left out (to which I have no objection whatsoever).

The unit is "Kelvin" or "degrees Celsius". Sometimes people add "degrees" to Kelvin, but that's incorrect and I've only ever heard non-sciency people do that. People often do omit Celsius or Fahrenheit, and I think there's nothing wrong with that when talking about the weather or other everyday temperatures.

You're saying the unit is "Celsius" and you can optionally prefix it with "degrees"? I've never heard it explain that way. Seems very weird.

If people google for "java download" they get this page: . On that page there is a big red button called "Free Java Download". That's the most straightforward way to download Java, and it gives you an installer with the toolbar (at least on Windows; I don't know on other platformst).

Not only that: even if you install Java from a non-toolbar installer, the automatic updates (if they even work) use the toolbar-version of the installer AFAIK.

That's why people say there's a toolbar in the Java installer.

Asimov was on a TV show where the host asked him about his earlier prediction that the world would only have five computers. Asimov asked that the question be cut, where the confused newscaster pointed out it was a live show. So Asimov walked out of the interview.

Citation needed.

AFAIK Asimov never said that; it was an IBM executive, IIRC.
