Guilty as charged, m'lud...  First computer I programmed was a PDP-8 i.e. 
octal, but that would've been in FOCAL or BASIC.  My first hex was the 
mighty IBM-360/50 (and I loathed EBCDIC ever since).

Ah, memories.  One of the biggest challenges we faced in porting Unix to
the Interdata 8/32 was starting to do everything in hex.  I can truly say
that I learned it by single-stepping through bootstrap code and reading
the panel lights...

As a friend of mine once said to a young programmer "I've written boot
loaders with fewer bytes than you use for variable names!"

Clearly a reference to Dave H's PDP-8 with its 16 word (24 byte) RIM
loader.

The RK8E bootstrap for OS/8 was even shorter: just two instructions.
The first loaded a block from the disk (you forced it to be block 0 loaded
at address 0 of field 0 by using the CLEAR key on the front panel first),
and the second was jump-to-self, which executed until the disk overwrote
it with code that waited until the block had been loaded and then continued
executing the newly loaded code.

Still further off topic, but it reminds me of a Y2K incident circa 1960.
Our IBM 7090 had been fitted with a homegrown time-of-day clock (no, big
blue did not build such into their machines back then). The most significant
bits of the clock registered the day of the year. On day 0x100 the clock
went negative and the system went wild.

Today is The Day of the Programmer, being the 0x100'th day of the year.  
Take a bow, all programmers...

Did you know that it's an official professional holiday in Russia?
