Looking for a good time series data storage and analysis service. Maybe it’s bamboo: OEmbed Link rot on URL: https://twitter.com/pypi/status/282975117741527040

bamboo is an application that systematizes realtime data analysis. bamboo provides an interface for merging, aggregating and adding algebraic calculations to dynamic datasets. Clients can interact with bamboo through a a REST web interface and through Python.

bamboo supports a simple querying language to build calculations (e.g. student teacher ratio) and aggregations (e.g. average number of students per district) from datasets. These are updated as new data is received.

Wow! I didn’t realize how easy it was to run a Spark/Mesos cluster on Amazon EC2:

The spark-ec2 script, located in Spark’s ec2 directory, allows you to launch, manage and shut down Spark clusters on Amazon EC2. It automatically sets up Mesos, Spark and HDFS on the cluster for you. This guide describes how to use spark-ec2 to launch clusters, how to run jobs on them, and how to shut them down. It assumes you’ve already signed up for an EC2 account on the Amazon Web Services site.

Might be fun to just spin one up and run against some Common Crawl data.

Jean-Louis Fuchs has collected some essential IPython videos:

These are videos you have to see, if you don’t know ipython yet! I’ve worked as a programmer for more than 15 years and I thought I’ve seen it by now, but ipython got me as excited as I was when I dialed into a BBS first time… it bursts your horizon.

Parkin’ this in case it helps someone else, including me in the future. Oddly difficult to find documentation on the feature, the closest being an aside on distutils config files.

When building a Python package that has a C extension you can build the extension separately, using the build_ext command. This allows you to control the include directories, link directories, and link libraries. Handy for those ornery libraries that you just can’t install in /usr/lib or thereabouts. I recently needed it for geos and Shapely.

I don’t know if the games are any good, but I’ll give Michael Cook a +1 for a moby hack. Growing games is sort of cool.

But +11 for a tail-recursive acronym:

On Friday, however, Cook released a game called A Puzzling Present which shows off the much of the hard work Cook’s put into Angelina (a tail-recursive acronym for “A Novel Game-Evolving Labrat I’ve Named ANGELINA”). Instead of a simple platformer with maps and obstacles, the latest games by Angelina now include new mechanics for the player (in this particular seasonal game, the character is Santa Claus) at each level.

The call for papers for ICWSM, the International Conference on Weblogs and Social Media, 2013 is out. I’ve been a reviewer and attendee in the past and may actually be able to submit something this year. Yeah!!

But, according to Danah Boyd there might have been a bit of a botch:

In the end, I found that there was such extensive miscommunication that the gulf between what I had stated upfront as being key to me running the conference was miles away from what AAAI would find acceptable. Both of us felt as though we were contorting ourselves to make this work and it left both of us very bitter and unable to work with one another. I decided that I could not run a conference that wasn’t accessible to many of the core parts of my research community just to please other parts of the research community. I felt trapped and realized that it would be better to walk away than to let go of my principles.

Boooo!!

Victory!! Your’s truly ends the season on a five game winning streak and takes the regular season title on point differential. Onwards to the Fantasy Playoffs!!

The matchup was unnecessarily tense in that I started RGIII (17.47 points) over Cam Newton (39.17 points). Given the weather, rainy, and opponent, Ravens, I was seriously leaning towards benching Griffin. Instead I went with the “don’t get cute” mantra. Similarly, I went with an oversold Greg Jennings instead of reliable Randall Cobb.

Thankfully, I made a great waiver wire pickup in Knowshon Moreno for 24 points. And no one else underperformed. Thankfully Arian Foster collected just enough garbage time points to get me over the hump. A five point squeaker that had me sweating into the second half of Monday Night Football.

Feeling good about my playoff chances although my opponent has some scary explosive players in Josh Freeman (hot, good matchup), Torrey Smith (overdue), Calvin Johnson (he’s Megatron), and Adrian Peterson (’nuff said). I’m guessing I’ll need someone to go way over projection to pull this one out.

Criminy, I know it’s the Verizon Center, but there’s no need to jam the AT&T cells!!

Or at least that’s what it feels like whenever I come to a Wizards game. All I want is to check some stats, lookup random trivia, and pen the occasional blog post. Is that too much to ask? #firstworldproblems

IPython dev is funded, starting in January. We won’t have to relegate contributions to nights and weekends. 2013 will be an exciting year.

Cool! Hoping the IPython notebook get’s even more useful and interesting.

I like Python. I like PostgreSQL. I like PyCon. I should like PyPgDay.

In coordination with the Postgres community and PyCon US 2013, PyPgDay is occurring in Santa Clara on March 13 from 9am-6pm.

PyPgDay will be a full-day event with seven talks about PostgreSQL and Python, including talks by contributors to PostgreSQL, Django, PostGIS, and Python. Half the talks will help PostgreSQL DBAs, and the other half will focus on developing Python applications using Postgres features.

Link parkin’: Crawley Project

Crawley is Pythonic Crawling / Scraping framework intented to change the way you think about extracting data from the internet

It’s never actually materialized, but I’m still hoping that user grade, commodity cost, focused crawlers become a reality. Seems like the tech has caught up with the concept. Maybe something like Crawley plus Python’s copious machine learning and data mining toolkits could provide the foundation.

I believe not actually telling folks you’re exploiting focused crawling is one of the key tricks.

I’m not in the “everybody should code” cargo cult, but a bit of knowledgeable advocacy for one’s discipline is always welcome. Looks like Douglas Rushkoff is getting a chance to do some stumping for Computer Science education:

This week is Computer Science Education Week, which is being observed around the United States with events aimed at highlighting the promise — and paucity — of digital education. The climax of the festivities, for me anyway, will be the opportunity to address members of Congress and their staffers on Wednesday in Washington about the value of digital literacy. I’ve been an advocate of digital culture for the past 20 years, and this feels like the culmination of a lifetime of arguing.

Knock ’em dead!

Memo to self, read Program or Be Programmed over the holidays.

Link parkin’: graph-tool

graph-tool is an efficient python module for manipulation and statistical analysis of graphs (a.k.a. networks). Contrary to most other python modules with similar functionality, the core data structures and algorithms are implemented in C++, making extensive use of template metaprogramming, based heavily on the Boost Graph Library. This confers a level of performance which is comparable (both in memory usage and computation time) to that of a pure C/C++ library.

The Boost Graph Library gives me the willies though. I’ve never had much luck building or using it embedded within Python. Weird linking or dynamic library loading issues got me. At a 2.x release though, this module might be worth a test drive.

This nugget from Jacob Kaplan-Moss is a bit old, and from a Django-centric perspective, but captures what’s been tripping me up with Python web app frameworks and building RESTful APIs:

Conflating models and resources

In the REST world, the resource is key, and it’s really tempting to simply look at a Django model and make a direct link between resources and models — one model, one resource. This fails, though, as soon as you need to provide any sort of aggregated resource, and it really fails with highly denormalized models. Think about a Superhero model: a single GET /heros/superman/ought to return all his vital stats along with a list of related Power objects, a list of his related Friend objects, etc. So the data associated with a resource might actually come out of a bunch of models. Think select_related(), except arbitrary.

Victory! A satisfying win over the league leader avenging an earlier loss this fantasy season. That makes for four wins in a row. RG III closed the door on Monday Night Football, but if I’d have started Cam Newton, the deal would have been done Sunday night.

On my side, it was mostly pedestrian performances with RG III scoring 18, Arian Foster and Stevan Ridley for 13 apiece, and Tony Gonzalez (Go Bears!!) for 17. I will pat myself on the back though for grabbing Cecil Shorts off of the waiver wire and getting 17 points out of him.

I also lucked into my opponent’s QB, Drew Brees, having an uncharacteristically bad game, delivering 1.37 points. Brees is usually good for 20+. Hey, whatever it takes.

Now I’m locked into the first or second seed for our fantasy playoffs with one regular season game to go. Need a little help, but I already like how week 14 is working out.

— Wiz Win Last Night? (@DidTheWizWin) December 5, 2012

Somehow I lucked out and had a ticket for the second Washington Wizards victory of the season. Against reigning NBA champs, the Miami Heat, no less.

Have to say I was fairly subdued until the final minute, when I realized the Wiz could actually win. Otherwise, I was anticipating collapse, but the Heat never really turned on the defense.

I’m not rooting for Windows 8, but I hope it spurs Apple to do something interesting with the well nigh useless (for me) iPhone lockscreen. Brent Caswell takes a crack at a redesign:

What isn’t very straightforward is the lockscreen. I set out to make the lockscreen flexible and open to the apps on your device, without throwing everything that works really well out the window. But before I get to my ideas, how does the lockscreen work now?

Seems like a missed opportunity for both high utility and magnificent delight.

P.S. Without having to jailbreak the device.

On the drive in to work today I was listening to the local guy talk, faux sports talk, AM show. They opened a segment with a freestyle rap which I could immediately ID as Q-Tip but couldn’t place the track name.

DJ finally announced it as Excursions from The Low End Theory. Hit the parking garage, got outside of the building, and had it downloaded in 5 minutes through the modern miracle of LTE.

Life’s good, but why the hell have I been sleepin’ on The Low End Theory? Gotta’ get that on my Jesusphone 5 post haste.

The list of PyCon 2013 talks was announced:

As you may already know, this was an incredibly hard decision for the Program Commitee: we had over 450 submissions for only 114 slots on the program. Further, the quality of submissions was very high; the committee debated each and every talk very closely. I want to sincerely thank everyone who submitted a talk: the quality of PyCon comes from our speakers, and this year you all blew it out of the water.

Sounds like the potential for a great program. Unfortunately, I can’t be as excited as I was last year since I’m not as confident that I can get away. Still, I’m quite interested in the more hardcore groupings like “Big Data” (yeah I know buzzword compliant) and even more so in the tutorials lineup.

Following the Python PyPi Twitter stream reveals a number of toolkits that help you build RESTful APIs. These modules usually get you most of the way mapping models from an ORM into an API. However, where they’ve always fallen short for me is in easing the generation of search end points. Maybe I’m doing something wrong, but I need more help in 1) handling incoming query args, 2) turning them into searches against the model(s), and 3) generating a RESTful response, especially the resource URLs.

LazyWeb, make it so!

Torque is a (relatively) recently announced toolkit built on top of CartoDB 2.0 for performant browser rendering of large geospatially oriented time series data:

Torque allows you to create beautiful visualizations with big temporal datasets by bundling HTML5 browser rendering technologies with a generic and efficient temporal data transfer format created using the CartoDB SQL API. Torque visualisations work on desktop and ipads, and work well on temporal datasets with hundreds of thousands or even millions of datapoints. In anticipation of the Strata Conference starting this week in London, we have prepared some examples to share. Simon Tokumine will be there, so ping us for a private demo there.

Previously, I had found CartoDB a bit daunting for a hosted self-installation, but looking at the requirements now it doesn’t seem that bad. Feels like one of those tools where if you absorb the pain and get in on the ground floor, one can build a distinct competitive advantage. Working on tablets and desktops is a nice tease.

Finally got a chance to put supervisord into action at work. It’s very handy for organizing, launching, and managing a bunch of server processes. I’m especially liking the interactive command shell provided by supervisorctl. Plus I think it’s easily launchable from a cron @reboot action which is great for this non-root user.

How have I not heard of Pydoop until now?! OEmbed Link rot on URL: https://twitter.com/pypi/status/274179982736121856

Welcome to Pydoop. Pydoop is a package that provides a Python API for Hadoop MapReduce and HDFS. Pydoop has several advantages 1 over Hadoop’s built-in solutions for Python programming, i.e., Hadoop Streaming and Jython: being a CPython package, it allows you to access all standard library and third party modules, some of which may not be available for other Python implementations – e.g., NumPy; in addition, Pydoop provides a Python HDFS API which, to the best of our knowledge, is not available in other solutions.

Rafe Colburn’s reference to Christy Wampole’s How to Live Without Irony finally pushed me over the edge and I had to read her opinion piece. A good screed but before one gets all self-congratulatory about not falling for hipsterism, please check out David Foster Wallace’s “E Unibus Pluram: Television and U.S. Fiction”.

Admittedly Wampole is probably quite aware of the essay, but I’m not sure how many in the target audience are. This was the most impactful of the essays I read from DFW’s collection “A Supposedly Fun Thing I’ll Never Do Again” and has stuck with me for a very long time. Pretty much convinced me of the corrosiveness of television beyond the silliness of much of the content. Mule Variations has a good look at the importance of “E Unibus Pluram”, but it’s not a bad way to “ease” into DFW, if there is such a thing.

Hipsters are one thing but good luck assailing irony within mass media.

374 days of uptime, a bit over one year, is tricky with any machine and limited sysadmin attention. Pattin’ myself on the back, and a thumbs up for Linode. Now I can get get around to doing a distribution upgrade.

Victory!! A week ago, I said there wasn’t much sweeter than going into the Sunday night game, knowing you had a win in hand. Well that feeling is topped by going into Sunday period, fairly comfortable you’re going to win and clinch a playoff spot.

I didn’t really plan it this way, but I had two fantasy players in each of Thanksgiving Day’s three NFL games:

• Robert Griffin III lit up Dallas, and delivered 35 fantasy points.
• Miles Austin, thanks for nothing
• Arian Foster, got his usual 20+, 26 in fact, befitting the #1 overall pick
• Shayne Graham, got the benefit of overtime for 11 points out of the kicker position
• Stevan Ridley, picked up some garbage points in New England’s shellacking of the Jets, delivering 15.7 fantasy points
• I learned my lesson last week about the New England DEF and they rewarded me this week with 25 in the bank

Rolled into Sunday with 113 points on the board, and 2 players left. Going into Sunday night, Aaron Rodgers would have needed a historic fantasy performance without giving up much to Randall Cobb, who I was starting. Neither did particular well, which was fine by me.

That’s three wins in a row. And if my math’s correct, I’m back in the fantasy playoffs.

Wondering how hard it would be to build a good set of autodidact materials for learning probability and statistics similar to Think Stats and Baseball Hacks. The twist would be to use sports repositories ala Retrosheet, cleanly integrated into pandas for analysis (bonus points for iPython HTML notebook usage), and then have a follow up course on building data oriented, interactive web sites.

Might be a market for that.

Completely unscientific, coming from my mother-in-law’s basement in Palos Heights, Illinois, using speedtest.net:

• iPhone 5, AT&T LTE, 8.5 Mbps down, 0.9 up
• iPad 3gen, Verizon LTE, 24.2 Mbps down, 15.8 up
• iPhone 5, Comcast XFinity Wi-Fi, 0.5 Mbps down, 2.5 up

The XFinity pipe might be carrying the burden of IPTV on the cable box, but doesn’t seem like it’s living up to its billing. Upside is there’s no explicit bandwidth cap.

Verizon Wow!!

I’ve been a long time fan of Greg Linden, going back to the Findory launch. I don’t have a direct interest in his current projects other than they might open doors to computing for folks who hadn’t considered the potential:

Code Maven lets teens learn a little about how to program, starting with basic concepts such as loops then rapidly getting into fractals, animation, physics, and games. In every lesson, all the code is there — in some cases, a complete physics engine with gravity, frame rate, friction, and other code you can modify — and it is all live Javascript, so the impact of any change is immediate. It’s a fun way to explore what programming can do.

Code Maven is a curious blend of a game and a tutorial. Like a tutorial, it’s step-by-step, and there’s not-too-big, not-too-small challenges at each step. Like a game, it’s fun, addictive, and experimentation can yield exciting (and often very cool) results. I hope you and your friends like it. Please try Code Maven, tell your friends about it, and, if you have suggestions or feedback, please e-mail me at maven@crunchzilla.com

A diversity of hackers makes the world a better place. And who knows? Maybe My Little Guy (TM) will pick up Code Monster or Code Maven someday.

Good luck Greg!

Implementing Machine Learning. Now there’s a title I’d pay for, especially if it focused on modern graphical models. Programming Collective Intelligence goes part of the way on some of the basic approaches, but filling in the details on the stuff coming out of academic papers would be really helpful.

I wrote a pretty darn good “giving thanks” post last year. It’s still mostly in effect, so go read it again.

I’ll add two things for this year.

1. Health and Auto Insurance. You don’t need ’em til’ you need ’em, but I needed both this year. And I’ve been paying into Cadillac plans, which have now paid me back.

2. Our Veterans and Servicemembers. Working for a defense contractor you get an appreciation, but I’ve noticed a national uptick in public recognition as our wars wind down. I also got the rest of the story on why my did didn’t make it to the hospital for my birth. Drafted into the Army, he was escorting a casualty home.

Thanks to one and all who have, or do, help defend our country.

— Wiz Win Last Night? (@DidTheWizWin) November 20, 2012

I attended last night’s game against the Indiana Pacers. As the contest started, I noted that no one on the starting five could actually shoot. Washington promptly went down by 17 points. Despite a spirited rally, the Wiz of course fell short, unable to stop David West, and unable to get a good offensive possession down the stretch.

The scary thought is that the team probably won’t be all that much better when John Wall and Nene come back. Lottery here we come!

Victory!! In fantasy football there’s not much sweeter than going into the Sunday night game (much less Monday night) knowing you already have a victory in hand. That’s the situation I found myself in and I did it basically with a QB, a WR, and a kicker.

• QB: Robert Griffin III, 39.7 points
• WR: Randall Cobb, 19.8 points
• K: Shayne Graham, 14 points

No one else scored in double figures, including fantasy #1 Arian Foster, and his team scored 43 points! Not to mention some unfortunate early morning lineup changes. First, playing Denarius Moore instead of Eric Decker or Miles Austin. The latter two only score 8 points but that was 8more than Moore. Second, pulling the Patriots DST for the Rams. -20 on the GM.

New rule. Never play Raiders.

Have to admit I was feeling a little nervous in the fourth quarter of the 4 PM matchups. I was only ahead by about 4 points, and my opponent still had Willis McGahee in his lineup in a close game. Little did I know that McGahee was out with a knee injury or that Stevan Ridley would seal the deal with a cheap garbage time touchdown.

— Joe Hellerstein (@joe_hellerstein) November 14, 2012

As a longtime Sade fan, all I can say is nicely played Professor Hellerstein (Go Bears!!), nicely played.

Victory!! Back in the win column. My team did it despite a craptaculous performance from my wide receivers. Eric Decker and Miles Austin combined for a whopping 6.7 points.

Thankfully, Tony Gonzalez (Go Bears!!) was in my starting lineup for approximately 30 fantasy points. Running backs Arian Foster and Stevan Ridley showed up as well. Basically half of my team carried the load.

Frankly though, it’s pretty sad when you’re sweating it out on Monday night, hoping the kicker does just enough to keep the spread. Especially since my opponent had the Pittsburgh defense against Kansas City, a situation ripe for defensive scores.

A comfortable 17 point win all told and the league’s second position firmly in hand with four games to go.
