Clothes: What was once the bane of my childish existence was a boon this year. I have become one of those guys who wears whatever he has until it is falling apart, and the end result is a rather shabby-looking fellow staring back in the mirror. My wife, fresh from having pieces of herself removed during surgery last week, decided that it was time to freshen up my look somewhat. A new hoodie, t-shirts, a polo, and a new oxford were welcome sights, as was the gift card she gave me to go pick out more. With luck, I’ll stop looking like a refugee from 2001 this year.

Popcorn: My kids visited my favorite chocolate shop (The Chocolate Emporium) and bought me a bag of their chocolate-covered popcorn. While it’s a small setback for my diet, it is a welcome addition to my lunch this week.

Legos: My four year-old son gave me three small boxes with his Legos in them, saying that he wanted to give me his favorite toys. He also said that he hoped I’d share with him. Which, of course, I shall.

The B-Spot: My in-laws gave me a give card to Michael Symon’s B-Spot restaurant, which is my current favorite place to grab a burger and beer. Highly recommended. I’m saving it for a place to take my wife after she;s fully recovered.

I also received some birthday cash, and with that, I treated myself to some fiction I’ve been waiting to pick up:

- Transmetropolitan, Vol. 2: Lust for Life by Warren Ellis
- The Hidden Family by Charles Stross (Book 2 of The Merchant Princes)
- The Clan Corporate by Charles Stross (Book 3 of The Merchant Princes)

For myself, I picked up the latest MacHeist bundle. I’m using MacJournal from that bundle to write this post, and while I’m not sure that I love it, is does have some good points. I think I like vim better.

Finally, I decided to put my money where my mouth is and bought a monthly subscription to Thomas Gideon’s Commandline Podcast. The man is my tech news aggregator, after all. It’s important to support content creators, and Thomas is one of the best.

• My apologies for missing my TRICKSTERS update for the last two weeks. Between a big event last Thursday and my wife’s operation this week, I’ve just not had the energy to put out a good episode. I’ve written three lousy episodes, but as they are sub-par, I’m going to hold on to them and try to magically turn them into something decent for next week.
• My wife (Cathy) is recovering from he gall bladder surgery nicely…each day is a little better than the last. Thanks to everyone who has sent prayers, luck, and good wishes. She really does appreciate it, as do I.
• Thanks to everyone who is wishing me a happy birthday today.   In case I do not get to thank you personally, know that it is greatly appreciated.
• Want to know what I was up to in Atlanta? My interview about PyCon is now available at The Command Line podcast. 
• My review of Charles Stross’s Halting State is up on The Secret Lair.
• We’ve announced the winner of the Name Overlord Johnson’s Laptop contest.
• I am once again dabbling in Second Life. You can blame Sam Chupp for this.  I am known there as Brand MacIntyre…feel look me up. I am a lonely soul there, knowing no one.

Good night.

• We had three excellent keynotes, but the one that stood out was Mark Shuttleworth’s discussion of Cadence, Quality, and Design, in which he discussed the discipline of development on a timed schedule, and how it has helped the Ubuntu teams.
• David Beazley’s Understanding the Python GIL was as crunchy as I’d hoped. He did a series of tests on how the Global Interpreter Lock acts when dealing with threads on a single or and then on multicore machines. It was outstanding.
• Catherine Devlin gave a talk about how to build command-line interpreters using cmd and cmd2, then as a bonus explained how SQLPython can make your life better. A commandline shell that allows you to interface with Oracle, MySQL, or PostGRes as if you were in a Unix shell?  Yes please!¹
• C. Titus Brown’s discussion of implementing different continuous integration packages was as entertaining as could be, and brought home several good points (mostly, just use Hudson. Really.).
• Finally, Ned Batchelder demystified several layers of confusion during his talk on Tests and Testability.  I’m looking forward to playing around with his ideas at work this week.

I’m beat. There’s one more day of talks, then I’m on my way back home. Not sure when I’ll be able to get my Day Five post up, but I’ll try to do it before I fly out.

Thanks for reading!

1. This talk completely blew me away, and I’m wondering if she accepts sacrifices or tribute.

1. Van Lindberg formally opened the convention.
2. Steve Holden¹ gave an overview of what’s new at the Python Software Foundation, and what’s coming down the pike. THere was a strong emphasis on diversity as a key goal for the next year. These was also discussion about the possible creation of an Associate membership in the PSF wheere people could donate money and become a member. Nothing definitive on the latter yet, but it is under consideration.
3. Finally, Guido van Rossum put the twitterstream of #pycon tweets on the screen behind him and took questions from the stream for about 40 minutes. Of special note was his comment on Django vs. Turbogears (“Django. Sorry, Turbogears guys.”), Django in general (“Django sucks. But they all suck.”) and vim vs. emacs. (“I use emacs. I also use vim. I’m not very good at either.”)  In all fairness, it was hard to delve deeply into any one topic, so discussion was light and all in good fun.

After a short coffee break the various tracks started up. While everyone seemed to be getting something out the talks they attended, my personal experience was that it was rather it and miss. The single outstanding talk was an exploration of the Python Dictionary, explaining how it allocates memory, resizes itself, and assigns addresses in RAM. It sounds dry but Brandon Craig Rhodes did an excellent job, and was easily the best speaker of the my day. A close second was Grig Gheorghiu’s discussion of RESTful web services and how to construct them using restish.

The day finished off with a set of lightning talks, the highlights of which were Greg Wilson’s request for articles for his next book entitled Beautiful Software Architecture, Ned Batchelder’s report on recent changes to coverage.py, and David Huggins-Daines’s demonstration of PocketSphinx, a speech recognition engine which will transcribe .wav formatted audio to text.

By then end of the day, most of the folks I was hanging with were beat, so we split up and grabbed dinner. Some of us walked back to my hotel and hacked on code for two or three hours, which was fun. I haven’t been able to hack with a team since I left Mahalo, and I do miss it.

Tomorrow looks to be another full day. Check in late in the evening for a recap of Day 4.

1. Chairman of the Python Software Foundation

1. The talk started 30 minutes late.
2. We spent the first hour configuring our computers, something we could have done before the talk if there had been any notes circulated.
3. Even once we got there, there were no notes. The speaker would add the commands he was running to a notes.txt file, then we would go download it from his computer via HTTP.
4. When asked how to configure Firefox profiles on Windows, the answer was “I don’t know.” The Windows folks banded together to solve the issue, but…I mean…come on. You’re presenting to a multi-OS room. It’s your responsibility to understand the material.

<snip…>

Rather than get all frothy and unkind, I will only say that an ounce of preparation goes a long way. I did learn a few things, but the talk was so much less informative than yesterday’s tutorial that I left feeling that I would have done better just reading the docs on my own.

Now, that being said, this is not a problem with PyCon, just this one tutorial. I still have very high hopes for PyCon in general. Tomorrow is the first day of the formal conference, and I look forward to seeing what it holds.

Stay tuned for Day Three.

You’re not at DragonCon anymore, Mr. Miller.

The Regency is a very different place when not festooned with cosplaying geekazoids¹. That’s not to say there are no geeks, just that colorful superhero and anime costumes have switched to black shirts/hoodies and blue jeans. It’s not full the full-on stereotype, mind you: there are enough hipster-coders in the mix to break up the monotony.

At the time I write this, it’s 8:42 am and I’m waiting to filter in for the first tutorial I signed up for: Faster Python Through Optimization. This is after my first choice, Test Driven Web Development, was canceled due to the speaker’s business life stomping down on his lecturing life.

I’ve just been asked where the registration desk is again. Again, unlike DragonCon, there’s more than one convention in the hotel this weekend. People are confusing one with the other. It’s easy to tell the between the participants: khakis and colored oxford shirt? Manufacturing conference. Black Tee with laptop bag? PyCon.

So far, the wifi is…minimal. This is disappointing, but it’s still very early: I’m willing to bet they just haven’t gotten there yet.² The staff peoples are working hard this morning…I’m watching them lay powerstrips and set up cameras. It looks like there will be an archive of all the talks. This is great: I can use them for review later if my own notes are lacking.

Time to go. More later.

* * *

I must steal a line from my friend Kris Johnson to describe the Optimization talk. It was like a toasted wheat bagel: good for me, but very dry.

The speaker was well prepared: sample code was burned to CDs and a fifty-three page handout that contained all the information for the course. Any worries I had about not having complete notes are now gone.

(This is where the non-programmers can skip to the end. The rest of you, read on.)

The information was excellent. We started off looking at how to use cProfile and Guppy to benchmark and profile code. From there we wrote several tests for comparing operations on various data structures: finding the intersection of two lists vs. two sets, Slicing off pieces of a large list vs. using a deque. From there, looked at how to speed up various math functions with NumPy, using psyco for JIT optimization, then finally moved on to using the multiprocessing module to make the best use of multicore systems.  Finally, we looked at how to combine strategies to get the most bang for your buck.

While I was pleased with the content, the presentation was a little lackluster only for the reason that most programming presentations are challenged: the instructor mostly read from his notes. To be fair, he seemed a little nervous, and the fact that some of his examples failed because of configuration issues did not help the poor guy. I felt for him.  The interesting that happened was that people paired up when things went awry to solve the issues. I worked with a woman named Ada³ to figure out the problem with some of the timing functions in the code. The pair programming enhanced the talk, and I feel like I got more out of it.

(Welcome back, non-programmers.)

All in all, I’m pleased. I’ve already learned some new concepts and they are spawning new ideas that I’ll probably play with over the weekend. Tomorrow I’ll be heading to Testing Websites With Python and Selenium, which looks promising.

See you tomorrow for Day Two.

1. This is a term of endearment. I count some of those cosplayers as friends.
2. This was, in fact, the case. The hardworking staff fired up the internet connection, and everyone logged on at once, flooding it. About 15 minutes into the tutorial, the internet returned, and several gasping programmers logged in to Twitter. Myself included.
3. This flipped my geek bit a little.

The suggestion?  Thumbtacks.

I’ll be at:

• PyCon: Feb 17-21 in Atlanta, GA
• Balticon 44: May 28-30 in Balimore, MD
• GenCon: Aug 6-8 in Indianapolis, IN
• Con on the Cob: Oct 14-17 in Hudson, OH. This one will be something special…Kris and I have a Clever Plan we’ll talk about in coming months.

If you’re going to be at any of these, drop me a line and let’s find some time to meet up.

Also, the latest episode of TRICKSTERS has been posted on The Secret Lair. Remember the girl on the doorstep from last week? Yeah. There’s more to her than meets the eye.

If you head over to The Secret Lair, you will find the first episode of a work of serialized fiction called Tricksters.  It’s based on a writing prompt from two years ago, when Kris and I were meeting each morning at a local coffee shop to write. The ideas implied by the original piece have been lurking around in my head since then, and as one of my big goals for the year is to work on my practice of writing, I decided to jump in with both feet.

I freely admit that this a novice effort: I’ve long talked about writing fiction, and like many people, I’ve gotten caught up in buying books, reading blogs, listening to podcasts…doing anything but the actual work. That ends now.

Please check out the story. I welcome your thoughts.
