Is there “0b” or something similar to represent a binary number in Javascript
...gned a number that looks like it's in binary, but is actually being parsed base 10. The parseInt function expects a string as the first arg, so it turns it into "1111" (base 10 representation), then re-parses it as if it were base 2.

Do you use NULL or 0 (zero) for pointers in C++?

cerr << sizeof(void*) << endl;

On a 64-bit gcc RHEL platform you get:

The moral of the story. You should use NULL when you're dealing with pointers.

Divide a number by 3 without using *, /, +, -, % operators
...3 + a/1000*3 + (..). In binary it's almost the same: 1 / 3 = 0.0101010101 (base 2), which leads to a / 3 = a/4 + a/16 + a/64 + (..). Dividing by 4 is where the bit shift comes from. The last check on num==3 is needed because we've only got integers to work with.

...d with /LARGEADDRESSAWARE and can allocate 4 GB RAM when run under Windows 64 bit, unlike R.exe (we're talking about 32 bit R running under 64 bit Windows). Why would the R people do this only for Rterm.exe and not for R.exe, if Rterm.exe is obsolete?
