I just learned (*ahem* the Hard Way) that CPython 2.7.3 namedtuple is buggy when combined with pickling and older Python versions.

If you pickle a namedtuple using CPython 2.7.3, you won’t be able to successfully unpickle it using 2.7.2 (nor, presumably, using even earlier versions).

Here’s a short example. First, run this with Python 2.7.3:

# Pickle a namedtuple with python 2.7.3

import pickle
from collections import namedtuple
Point = namedtuple('Point', ('x', 'y'))

a = Point(4, 9)

with open('foo', 'w') as f:
    pickle.dump(a, f, -1)

Then, run this with 2.7.2:

I’ve been using Cygwin on my Windows partition to run a particular job every minute. Cron (Vixie’s cron) works perfectly, except that messages like this one were appearing (every minute!) in my Windows event log: …read the rest →

It’s funny. I’ve recently been told—by more than one person—that Sara and I are “brave” for planning to deliver our baby at home. This from people who are educated, intelligent and have my respect. And yet, they couldn’t have picked a worse way to characterize the decision. What’s going on here?

Read on, and then you tell me: isn’t it actually more courageous for a low risk mother-to-be to voluntarily walk into a hospital to give birth?

We’re back home. (Boo.)

We’ll post our photos as soon as we sort through [all 1500 of] them.

Heading to Phuket airport now. A mere 32 hours after we board our plane (Phuket -> Bangkok -> Tokyo -> JFK), we’ll be back in snowy New York.

For this final travelblog entry, I wish I could write something witty or amusing. But ending our trip has me so bummed that all I have to say is: it’s been a magnificent month.

Today’s plan is to:

1. have breakfast on our private veranda
2. beachcomb
3. bask by the pool
4. eat as much coconut ice cream as possible
5. get a beachside Thai massage
6. order fruit drinks by the coconut-full
7. lament that this is our last day here

We snorkeled the Similan Islands today. Remarkably, the breathtaking underwater landscape we saw (heaps of beautifully colored fish and coral) really did resemble the glossy posters in the tour company’s sales office!

Traveler’s Tip of the Day: When getting your hair cut in Thailand, don’t ask for it to be cut “short.”

After a few more hours of kayaking this morning (had some great wildlife sightings), we headed to Khao Lak for the final leg of our trip. We’re now at a 5-star resort just north of town, on a sparsely populated tract of white-sand beach. The contrast from last night is stark–we no longer need a flashlight to get to the bathroom. And instead of last night’s rudimentary, cold-water shower, we’ve got a teak-and-slate-appointed bathroom with a 2-person tub and 2 shower heads.

Besides kayaking, we’ve been doing some trekking here. Today’s hike was through a deep limestone cave, through which two different streams run. Thousands of bats, dozens of cave crickets, several large spiders, a few cave toads, and water deeper than our heads. At some points, I had to swim with one hand, trying to keep my other hand above the water (in that hand were: my [non-waterproof] flashlight, and our drybag, which held our [non-waterproof] camera.)

Definitely one of our trip highlights.

Today we arrived at our quaint “floating bungalow” in the remotest corner of Khao Sok national park. This is the third bamboo bungalow we’re staying at on this trip–and not the only one that hasn’t been on solid ground.
