RE: Anyone heard about this study?

When I do my 20 minute car commute, I obviously
don't compute. Me, I listen to NPR or the BBC.

When I take the bus, as I did today
(1 hour on bus, + 40 minutes walking, plus wait time)
I use my tablet PC and, mainly, read and delete email,
although occasionally I compose email and/or write code.
Hard too write code on the bus when I am pairing strictly.

Partly so... but the version I have heard (I believe on
NPR pop sci radio) is that it doesn't work out like that. 
You cannot make up for a sleep deficit through the weekend.
Some of the damage is irreversible.

Even if you don't live longer it might feel that way; your net
wakeful life might still be longer: hours awake per day * days
alive.

Y'all are missing a detail: I don't do all-nighters, either, and I don't set
an alarm clock without a reason.

Sleep is SUCH a totally effective debugging and bug-preventing technique!

I have this pattern. The whole Iterator thing is noise. Using the 
same trivial name -- iter is a common choice -- makes it just a 
bit easier to ignore allowing you to focus on what's important.

Hmm, I'm not any familiar with Lisp, but it this something like a list
structure?

Thanks a lot, all!

Sorry, but it looks a bit messy to me.

I hope it does. :)

I like this one better, too.

Java provides the Collection Framework, which I certainly don't want to
re-invent. 
I think this problem is going to turn into "when to introduce a new type".

I hope at least it solved a "drowsy morning" problem. :)

This is nice. I like it.

I guess it was only a Java issue...

And non-sleep such an effective bug-introduction and time-wasting tactic.
The referred-to-book says that one of the effects of sleep deprivation is
loss of judgement (experience says: oh yes) and, drat, forgot the term,
fixing/monomania/locking: you get stuck in a particular pattern and can't
get out (experience says: oh YES).

At home we're making a deliberate effort to take sufficient sleep. This
morning, for the first working day in quite a while, I woke before my
alarm. [Perhaps because Mr Cat didn't wake us at 4am "Purr! Purr! I
love you! Purr! Listen to me scratch the carpet! I'd like to go hunt now!
Purr!"]

No - it's *exactly* like a list structure.

[Everyone should learn one of the Lispy languages. It's not the syntax:
it's the *semantics*.]
