False. They are not "reconditioned". They are essentially rebuilt from scratch by the Aerojet with the major participation of Ukrainian "Yuzhnoe" design bureau. The mere fact that the entire fuel supply system ifs prvided by Ukrainians immediately requires a full rebuild. And, of course, the fact that the engine failed today is already a direct factual indication that this was not a Russian engine.

You are confused. Russian rockets are not designs from the 60s. By the average standards of the modern space technology, Russian space hardware ranks as 2040 design. I know that sounds strange, but USA and everyone else is so far behind Russia in that department that we have no chice but to consider Russian deisgns way ahead of the current time just to balance things right.

These people are not inventors of the blue LED. This specific kind of blue LED was invented in Soviet Union in the 1960's by the team of Zhores I. Alferov (the winner of 2000 Nobel Prize in Physics). Nobody disputes the priority on the invention itself.

After that the issue was to develop the manufacturing process that would make the mass-production of such blue LEDs feasible. The Japanese team did exactly that: they came up with the technology that allows one to mass-manufacture the Alferov's device cheaply.

There's no dedicated feature in C language that makes specifically `if (a = b)` possible. Your `if (a = b)` example is just a side effect of the fact that `=` operator in C behaves just like any other operator: it has a result and it can have side-effects. This is perfectly logical and useful way to design an operator.

You decided to make an `if` that depends on the result of `=` operator? Yeah, you can do that in C, but if you don't like it - it is your fault. Don't like it? Don't do it! Blaming it on the language is like hitting your thumb with a hammer and then blaming it on hammers.

`sizeof(string)` never "returns the length of a single byte".

`sizeof(string)` evaluates to the byte-size of `string` object. E.g. it evaluates to the full size of the character array, if `string` is a character array. Or it evaluates to the byte-size of a pointer, if `string` is a pointer.

It should not be too difficult to find a Russian-speaking person, who can read the Putin's speech in the original language and confirm that nothing like that was ever said by Putin. This is not even a "loose and creative" interpretation, this is a total and complete hoax. Propaganda writers of the US regime were working in DDoS mode for the last few months, pumping out copious amounts of uninspired garbage-quality nonsense. This specific piece of nonsense does not stand out in any way. Why is it suddenly here?

Imagine that you drew an Euclidean triangle on a piece of paper, measured its internal angles and calculated their sum. And suddenly you obtained 185 degrees as the result! What do you do in such case?

A) Assume that your measurements and/or calculations contain an error
B) Declare to the world that you found an triangle that tops the list of all Euclidean triangles known to man in therms of the internal angle sum.

I hope you have enough scientific literacy to realize that A is the correct answer.

The authors of the above research apparently belong to that peculiar group of people who chose B in cases like that. Sorry, geniuses, when you end up in situations when Canada tops your "list of most science-literate countries", you go back, review your research and find where you screwed up.

The most science-literate countries in the world are Russia and Belarus. Every time you obtain a different result, you just throw your "research methodology" into the garbage can and start over. Yes, it is a s simple as that. Class dismissed.

P.S. LOL! Canada...

No, you don't have "a Ford with adaptive steering". No Ford was ever made with the feature in question. Ford is just thinking about introducing it. You have a Ford with variable amount of steering boost. This has been around forever, even in hydraulic systems. But this is not adaptive steering discussed here. Adaptive steering requires variable steering ratio. Your Ford does not have variable steering ratio.

Despite the fact that such systems break the sold mechanical link between the steering wheel and the steering rack, they are normally rather well protected from mechanical failures. At least Honda's and BMW's systems will normally "fuse" steering shaft in case of any mechanical component disintegration, restoring the classic solid steering link. However, such systems are very susceptible to software failures and simple electrical failures (like water getting into electronics), when the systems "gets a mind of its own" and begins to steer the car overriding driver's input. There is an epic thread on e90post (now sanitized) about consequences of such failure in a E92 car http://www.e90post.com/forums/...

False. Electric boosters ("power steering") systems have been quite widely used for a while already. However, in this case they are talking about something totally different: ratio-changing and self-steering systems. So far only Honda used it in Japanese market and BMW used exactly the same system (as an optional feature) everywhere. Lexus also has its own a ratio-changing system, implemented differently. Overall, such systems are rather rare and typically offered as an option. It is not correct to say that anyone "switched" to anything like that.

This system was first introduced by Honda in the their JDM S2000. It was later copied by BMW as their "Active Steering" system and offered in USA in 5-series and 3-series cars. Note that such systems effectively break the solid link between the steering wheel and the steering rack. There were a number of reports of Active Steering failures in 3-series BMW E9x cars. BMW abandoned the system for in new 3-series, replacing of with ordinary electric booster without ratio-changing ability.
