*snigger*
My ex-boss just wandered over to brag about a neat piece of machine code hackery he'd just worked out (specifically, single ARM instructions that set the N, Z and C flags to any meaningful combination of values).
I promptly flicked over to my editor window, and opened up a text file I wrote within a month of arriving at ARM (i.e. four and a half years ago) containing exactly the same analysis. Then I showed him the timestamp. He was a bit put out >:->
(Somewhat spookily given there are many equivalent instructions for most possibilities, we turned out to have produced exactly the same table. Evidently I absorbed the ARM groupthink excessively fast…)

Smug
Talking about smart, I have just managed to break G's Darkness Bounces. It only took about 3 weeks of very cunning and very _nearly_ right solutions to find one that actually worked. I did Longitudinal Thinking in no time, as I'd seen the solution. Am currently quite stuck on Simply Explosive.
Re: Smug
Shame LT was spoiled for you; I thought it was particularly nice. Good luck with Simply Explosive...
(I did SE a week or so ago, and I've been resting before making a serious attempt on Lack of Substance.)
Re: Smug
In a way I was glad I knew the solution to LT, as otherwise that would have taken me a week or so, rather than the hour or so it actually did. SE is quite quite tricky; that will probably take me a lot of time again.
Obviously I'm doing such a lot of work on my degree. I'm beginning to think I should have done something that required less work.
