Cool. pprint is also really useful

Thank you. Added the link to your gist to the post.

Ah, cool, thanks for sharing the stack overflow discussion. So set is equal to frozenset speed?

The apparent benefit to frozen sets, we determined over on Stack Overflow, is actually an accident caused by the order in which the set and frozenset get to run in your code — probably, I think, because they share most of the same code and the one that gets to run first in your loop gets the penalty of bringing that code back into the L1 processor cache. Your post got mentioned several times: http://stackoverflow.com/quest...

Hi! I just wanted to let you know that the tests you're running are not totally valid. `frozenset` and `set` instances actually seem to do lookups at about, or maybe exactly, the same speed. I modified your test code a bit, so that it just does the `set` and `frozenset` tests, alternating between them, and found that the first test or two that runs is quite a bit slower than the subsequent ones, probably due to having stuff pre-loaded in the processor cache.

The modified tests are at https://gist.github.com/629781...

regarding your last bullet about getting into development: in case your don't already know, you can also do scripting stuff on android with python and some other languages.

that is pretty awesome. I can see that really coming in handy during travel, I have issues every time I fly because I hate to pay for airport wi-fi when it's not offered for free.

I'm also interested in hearing your big-picture thoughts, given your pretty extensive recent experience with the three prevalent smartphone platforms.

Yubnub is def pretty cool. I used to use it when I had firefox.

What are you up to these days? Still in school?

Hey Kortina, have you seen http://yubnub.org/ ? I've been using keywords in firefox for years now.

you could have just asked me ... but i forgot this command too. this is quite useful. my hack of away of doing this was do an undo then a redo and be on the last edited line (added benefit, knowing what you edited). i used to be nasty with this stuff. had to use ":set invlist" to work on a cross platform issue in a textfile. i need to setup a good .exrc file. i'm sure i can find my old one somewhere. shoot me yours if you think it's pretty good.

Re: Optimize for Flow, a Response to Lessin’s Over Value Your Time Suggestion

But the flow concept also applies to other aspects of life, not just work time. Like I stayed till late at that NYTM after party. I went with the flow.

Re: Optimize for Flow, a Response to Lessin’s Over Value Your Time Suggestion

paramendra — Thu, 04 Mar 2010 03:45:23 -0000

The key concept here is Flow! :-)

I am a big fan of freehand exercise. You can do them anywhere, any time.

It was good to meet you at the NYTM after party. Thanks for the 40 cents. I feel richer! :-)

Re: Optimize for Flow, a Response to Lessin’s Over Value Your Time Suggestion

kortina — Tue, 23 Feb 2010 09:41:33 -0000

Excellent counter argument. I suppose this is why I more often than not opt
to go walk to a coffeeshop instead of brewing at home. Maybe the difference
is this: for me, coffee is "break mode" so I want the random interactions /
fresh air, but when I workout I don't want to be social, I want to exercise.

I also think your argument makes a lot of sense when walking is transit mode
(I prefer walking to work then taking the subway, which usually takes less
time), because it is a good time to think and get fresh air. So for me,
there is some benefit to transit time because the mode is walking. For most
people in our country, however, I think the default mode of transportation
is car, and the ancillary benefits of fresh air and sunlight are lost
(unless you're driving a convertible).

Good point, though, and I agree with you, especially if the decision to walk
is a conscious choice.

Re: Optimize for Flow, a Response to Lessin’s Over Value Your Time Suggestion

aweissman — Tue, 23 Feb 2010 08:30:26 -0000

But here you are not factoring into the equation the cost to yourself of not getting outside, not getting fresh air, not seeing random people doing random everyday things, someone smiling at you on the way into the gym, the cup of coffee you buy on the way out etc.

I'm not saying all that is better - just that in doing a value of time equation that is a cost part of the numerator to figure out.

Re: Optimize for Flow, a Response to Lessin’s Over Value Your Time Suggestion

EricFriedman — Mon, 22 Feb 2010 22:48:10 -0000

Definitely want to get to the same point - until then I schedule time for the gym and pay a premium to go around the corner from my house. Its not as good as your system, but works.

Hmm, that is a great question, Allison, I'm going to ask my friend Vishal
who may have a better idea about this.

Re: Ayurveda, Digestion, and City Spontaneity

Allison Bojarski — Sun, 21 Feb 2010 15:48:44 -0000

Any thoughts on how drinking ice-cold water might affect someone mid-workout if it's an intense crossfit-style workout where one (sometimes) already feels kind of nauseous?

Perhaps room-temp water would be better and less disruptive even to an empty stomach?

Re: The Distributed Marketplace for Secondhand Goods

kortina — Fri, 19 Feb 2010 07:42:54 -0000

I'm selling at cost. I bet you could get more, but I'm not trying to make
money, just recover my cost.
