Look at the bright side. You now know one more company where you DON'T want to interview.

comment dealing with a very large state machine in a class
Is there any chance you can get your employer to junk the protocol specification and START OVER??? Alternatively, out of morbid curiosity, what protocol is this, and where can I find the protocol specification?

comment Ambiguous If-else nested block in C without braces
Because this is how C is defined to work. There was (and still is) a REASON why Ada required all control structures to be fully bracketed. Ichbiah et al. KNEW that the "dangling else" problem was Bad, and they Fixed It.

comment Testing multi-threaded race conditions
@PeterK., this is one of those few cases in software development, along with monitors, RAM, and disk drives, where bigger IS better.

comment What is the ideal length of a method?
so am I. The correlation study looked at LOTS of code, and LOTS of routines. (It was one of the big public repositories.)

comment When do you use float and when do you use double
"Modern computers" meaning Intel x86 processors. Some of the machines the Ancients used provided perfectly adequate precision with the basic float type. (The CDC 6600 used a 60-bit word, 48 bits of normalized floating-point mantissa, 12 bits of exponent. That's ALMOST what the x86 gives you for double precision.)

comment What is the ideal length of a method?
Cyclomatic complexity has been shown, on large quantities of real production code, to be VERY strongly correlated with raw SLOC, making the computation of cyclomatic complexity a total waste of time, energy, and clock cycles.

comment What is the ideal length of a method?
It isn't so much "get off my lawn" as an observation that I have seen a LOT of crap code over the years, and it seems to be getting WORSE.

comment Has there really not been one thing in the past 20 years that provided huge software development gains?
There seems to be an assumption underlying the question, that programmers would actually choose to use something that offered significant demonstrable benefits. Whether that assumption is justified seems to me to be very much in question.

comment Optimizing code by using registers, but what if they are not enough in number?
@randomA, the value may or may not reside in memory, depending on the target architecture, the compiler, the optimization level chosen, other code, and the phases of the moon, Mars, and Uranus. If the target machine has enough registers, and the compiler recognizes that there is no need to store the temporary in memory, it will just leave it in a register. NB: If you are on an x86 processor, the compiler essentially has no registers to play with, and everything must live in memory.

comment Optimizing code by using registers, but what if they are not enough in number?
@delnan The compiler is required to obey the semantic roadblocks. The programmer may know that the roadblock does not apply in this case, but there is no way, other than explicitly assigning a temporary, for the programmer to convey that knowledge to the compiler.

comment Why was the first compiler written before the first interpreter?
McCarthy did not write the LISP interpreter. McCarthy invented a mathematical formalism. Steve Russell, one of the students in the MIT AI Lab at the time, realized he could write an interpreter to execute McCarthy's flights of fancy, and the rest is history.

That's one way to do it. You really only need two, EQUALS and one of the unequal cases.

comment Why does C dominate in the embedded software market?
Correctness is always #1 on the list of requirements for a production program. Performance is #2. Far too often, programmers are not only willing but downright foaming-at-the-mouth eager to abandon enforcement of correctness in the name of performance.

comment Why are floats called “real numbers” in some languages?
I think you have the question backwards. At a time when most of the existing languages were using "real" to mean floating-point (as opposed to integer), C chose to use "float" instead of "real". Your question could just as easily, and more correctly IMHO, be stated as "Why does C (and its derivatives) use "float" instead of "real" to denote (machine-approximate, i.e., floating-point) real numbers?".
