Unifix Linux was the first Linux distribution to be certified, back in the Linux 2.0 days.
"Certified" as in "passed the Open Group test suite and was thus certified as being able to be described as a Unix system"? ("The vendor claims it's POSIX-compliant" doesn't count as "certified".)
On the other hand, we do think that the laws of the universe should be based on the same principles at all levels, so the fact that General Relativity and Quantum Mechanics do not mesh well is a problem we need to solve. If some physics people want to look for other ways to solve the problem fine
Likewise, general relativity is only now getting empirical evidence that supports it as the most likely out of competing theories. We must recall that the impetus of general relativity was a lack of symmetry in the mathematics of Maxwell laws, having to do with identical magnets moving with respect to one another.
You gave a list of problems that don't fall under the umbrella of General Relativity, or do, but are problems that require more computational power than we have right now. General Relativity, is, by and large, understood at this point.
So when you say "general physics" you mean "general relativity"?
Is that toothbrush on the internet of silly things?
Depending on the definition of "internet", this toothbrush might be. (It might not use the Internet Protocol running atop Bluetooth, but it does connect to a machine that probably is connected to the Internet.)
I like the idea of hacking someone's toothbrush.
That might be difficult if, as per the All About Circuits posting I referred to in a followup, there's a "code protection feature" in the microcontroller that makes it difficult if not impossible to overwrite the code. You might still be able to overflow a buffer and cause a return to code you supply, for example - if the microcontroller isn't a Harvard-architecture processor only capable of running code from code memory.
So don't assume all the code in your toothbrush was written in assembler language; some of it may have been written in C, although some of the low-level library routines might be written in assembler (or an asm in the C code).
Hell is a place of eternal torment, in which there is no hope of peace or salvation...

Integrated circuits weren't invented until the late 1960's
That's not really true, the AGC was using IC gates around 1962 already.
Perhaps they're thinking of MSI, which first showed up in the late 1960's; SSI predated that.
Although this video doesn't mention it the Megaprocessor is actually a clone of the 6502, based on the reverse engineering of that chip which was done by the visual6502 people. Actual discrete transistor designs were a bit more streamlined to reduce the discrete component count.
Which is peculiar because the 6502 should have not nearly as many as 40k transistors.
And, in fact, the 6502 had more like 3.5k transistors; the MOnSter 6502, which is what the "clome of the 6502" person was actually thinking of, has about 4300 transistors.
Although this video doesn't mention it the Megaprocessor is actually a clone of the 6502, based on the reverse engineering of that chip which was done by the visual6502 people.
No, you're thinking of the MOnSter 6502. The Megaprocessor has its own instruction set, with 4 (semi-)general purpose registers (some load and store instructions can only use R0 or R1 as the register source/destination and R2 or R3 as an index register).
You could always use OSX. However I don't trust that one day Apple won't start verifying the hardware is genuine and your install stops working.
Yes, there's no guarantee that any version of Mac OS X^W^W^WOS X^W^WmacOS will run, or that it will continue to run, or that the next release after it will run, on a Hackintosh.

You don't NEED to "pick up the values" when it comes to Celsius.
So it's intuitively obvious, to somebody unfamiliar with Celsius, Fahrenheit, or any other temperature scale, other than knowing the values of the freezing and boiling points of water, that 20 to 25 Celsius is a reasonably comfortable temperature, that 30 Celsius is getting a bit warm (as in "you probably don't want to wear anything long-sleeved"), and 35 Celsius is in the "hot enough for you?" range? (Note: my choice of multiples of 5 is somewhat arbitrary.)
Especially when it comes to something like coffee, where 100 is boiling and 0 is frozen. Especially if you know that water cannot usually be heated past boiling point. You know, 100.
And that tells me what 65C is like, other than "in the range of 2/3 of the way from the freezing point to the boiling point"? I know drinking boiling water would not be good, but I don't know what 65C/149F water is like. (This whole discussion does mean I'd like to do some measurements so that I know what, for example, the temperature of my tea is once poured, and what it is when I find it comfortably drinkable. But the numerical values would be completely arbitrary, so either scale would work equally well for me.)
I don't know where they got 149F from, the report says 70C, which is 158F
What The Fine Report - or, rather, The Fine Press Release - says is both
Studies in places such as China, the Islamic Republic of Iran, Turkey, and South America, where tea or maté is traditionally drunk very hot (at about 70 C), found that the risk of oesophageal cancer increased with the temperature at which the beverage was drunk.
and
“Very hot” refers to any beverages consumed at a temperature above 65 C. See the Q&A for more details.
Experimental studies with animals suggest that carcinogenic effects probably occur with drinking temperatures of 65 C or above. In cancer epidemiological studies, people have been asked to describe the usual temperature of beverages they drink. In addition, surveys from regions with a high incidence of cancers of the oesophagus have found that the temperature of very hot drinks was more than 65 C. Therefore, the definition of very hot beverages as temperatures of 65 C or above comes from studies in animals and is also supported by real-world measurements of drinking temperatures of beverages. In contrast, the typical drinking temperature for tea and coffee in most parts of the world is below 65 C.
The unit widely used in most scientific contexts - as well as most parts of the world?
I also stumbled over not having a clue how hot 149F would actually feel - and had to take a look at the original paper if the WHO actually published it in a nonsensical unit...;-)
I have no clue how 149F would actually feel either, and I'm a Yank living in Yankland. "Probably somewhere between uncomfortable and painful" would be my guess, but, then, that would have been my guess had they said "65C" as well. I don't think I've experienced personal exposure to temperatures outside the range [-18,38]C/[0,100]F, so all I'd say about temperatures outside that range is "somewhere between uncomfortable and painful".
But now I'm curious enough that I might actually see if I can measure the temperature of our tea.
I do find it hard to believe that the WORLD Health Organisation gave their numbers primarily in Fahrenheit.
And, as you're probably implying here, they didn't.
The only place where, as a Yank, I might currently find Fahrenheit more familiar than Celsius are 1) "how hot/cold is it in here/out there?" and 2) "do I have a fever?", just because I'm used to the ranges; living outside Yankland I'd probably pick up the "yow it's {hot,cold} out there!" and "better take it easy and stay in bed today" values pretty quickly.
65C and 149F are both "OK, how hot is that in real-world terms?" values for me; 65C is no more "so what does that mean in real life?" than is 149F. I know the water was 100C/212F at one point (when the teakettle was whistling), but I don't know how hot it was when 1) I took the first "a bit hot, I'll let it cool down" sip, 2) when I actually started drinking it, and 3) right now (although it's probably well below 35C, and perhaps even below 30C, now).
While I'm not exactly a fan of Gawker, nor do I think Hulk Hogan's lawsuit was unfounded - the problem I have is that a very rich person basically paid lawyers to find problems and subsequently destroy a media entity that he didn't like. This is somewhat dangerous precedent - don't piss off the rich.
Translation: Rich people should have fewer rights than I do.
"And 70 per cent of patients saw a complete stop to the progression of the disease, while 40 per cent saw a reversal in symptoms such as vision loss, muscle weakness and balance loss."
Also, 70 + 40 = 110, WTF?
An article in the Toronto Star about this indicates that, of the 24 patients, "seven saw their symptoms deteriorate even after the transplant", although "this progression levelled off after about two years, Freedman said." (24-7/24)*100 ~= 70, so 70 percent apparently had no progression of symptoms after the treatment.
As for the 40%, presumably 30% saw a stop in the progression of the disease but no reversal of symptoms, 40% saw a reversal, and 30% saw no immediate stop although it appears that the progression at least leveled off after 2 years.

Yes, and one of the people in question has done precisely that ("loop quantum gravity").

We must recall that the impetus of general relativity was a lack of symmetry in the mathematics of Maxwell laws, having to do with identical magnets moving with respect to one another.
General relativity, or special relativity?
You gave a list of problems that don't fall under the umbrella of General Relativity, or do, but are problems that require more computational power than we have right now. General Relativity, is, by and large, understood at this point.

And, yes, there are people who want to hack their toothbrushes.
(For more fun, try a Web search for "toothbrush microcontroller" - that's how I found all those links.)
Here's a electric toothbrush reference design from Texas Instruments.
Here's the MSP430G22x0 microcontroller used in the design.
Here's a list of software tools for that microcontroller. The list includes something called "GCC", which they say is an "Open Source Compiler for MSP Microcontrollers".
Here's a page from Renesas about electric toothbrush designs.
Here's a list of software tools for Renesas processors; they list C compilers for the R8C and RL78 microcontrollers, as mentioned in the previous page.
So don't assume all the code in your toothbrush was written in assembler language; some of it may have been written in C, although some of the low-level library routines might be written in assembler (or an asm in the C code).

Somebody else built a discrete-transistor 6502 processor.
And, of course, there's the non-integrated-circuit TTL 8008, although that was probably SSI or MSI, not discrete transistors.
