Calendar (Wiki) History (2004-2016)

Boston Perl Mongers

from old wiki entries of Ronald J Kimball & Bill Ricker


Boston Perl Mongers history is divided into three parts, like Gaul.

Key Highlights (annals)

(Note. This file is in reverse chronological order, most recent at the top. the others are chronological, recent at bottom. All start with a table of contents by year.)

Tech Meetings have traditionally held on the 2nd Tuesday of every month, most recently at MIT.

The MIT Era 2005-08-09 - 2020-03-09

For 15 years, MIT IT and Facilities provided user group meeting space on campus for the convenience of MIT staff and other community members who wished to attend.

The facilities were very nice MBA case rooms in the Business & Humanities building E51.

MIT Era spans the file break between Mid History and Recent history.


December 13th - Christmas Lights Tour - Bill & Greek Chorus

A mutually-guided tour of the first half of several Perl-ish Advent Calendars XmasLights33.png

Around this time of year there is a tradition in the programming communities to share our favorite libraries, tools, and tips we’ve gathered over the past year. These prizes are dolled out once per day in classic Advent Calendar style. In the next meeting we’ll take a look at the highlights from several in-progress Perl-related calendars, including:

and maybe more from the master list via Advent Planetwhich has other languages and sysadmin, perf, …, and a code based puzzles.

(Audience participation: As usual, our Greek chorus answers each other’s questions about the modules seen.)



2nd Tuesday in November in a Leap year is Election Day - I presume most people will be watching a different channel that night.

We often do social in December.

Tues Oct 11th, room E51-376 Bill Ricker, Perl 5.22 & Abe Lincoln’s War Cipher

Last month, I did my usual Cryptographic History talk before’s GPG/PGP key-signing. The title was “Transposition Cyphers in Historic Context”, looking at a theory and two specific uses, President Lincoln and German Army Corps WW1. As usual, there was a bit of Perl code used for demonstration - for Lincoln’s.

This time, I used the 5.020 experimental features, postderef and signatures, that we’ve discussed in new release feature reviews (both promoted to stable in 5.024, so safe to use in real code).

BLU saw the history, but this month, gets to see the code.

Tues Sept 13th, room E51-376 - Brendan Gregg’s FlameGraphs (Bill Ricker, moderator)

FlameGraph of cpu of mysql

I stumbled on a link to a set of posts and hand-drawn ‘zines’ about Linux debugging and ‘doing’ software at . The Linux Debugging zine includes several ‘old friend’ tools (which gives me confidence in this person’s opinions) and also included new or new to me options and tools, and specifically enthused over Brendan Gregg’s invention: FlameGraphs.

Brendan Gregg invented these to make sense of profile stack samples of MySQL, which produced so much data that he had to invent a new way to visualize … with Perl, naturally. Tim Bunce has bundled and enhanced FlameGraphs into CPAN NYTProf, but it’s usable with any profiler giving full stack traces with symbols (Dtrace, perf, SystemTrap, OS X Instruments, Xperf.exe, NYTProf for Perl). -Bill Ricker

We will watch a video by the author and play with the source code.

March 8th - Rakudo Perl 6 and MoarVM Performance Advances - J. Worthington

(By the magic of video - Yapc::EU)

“Performance has long been one of the blockers to greater adoption of Perl 6. The language is designed in expectation of a sufficiently smart optimizer, knowing that such things are possible - but setting quite a challenge for those of us working on Perl 6 implementation. Following the”make it work, then make it fast” approach, we’ve done a lot of work over the years on getting many language features to work well in Rakudo. … In this session I’ll discuss how we’ve been improving Perl 6 performance by working at all levels of the implementation: optimizing built-ins, improving the Perl 6 optimizer’s ability to simplify code, and building a powerful dynamic optimizer for MoarVM that uses run-time information about a program’s typical behavior to cheapen attribute accesses, resolve dispatches, eliminate type checks, perform inlining, and much more. I’ll also take a look at the MoarVM JIT project, and how that is helping.


Finally, I’ll take stock of where we’re at so far using latest benchmark results: what we can do about as well as Perl 5, where Perl 5 comes out faster, and where Rakudo Perl 6 comes out ahead.”

Feb 9th, - Parallelism, Concurrency, and Asynchrony in Perl 6. - Jonathan Worthington

Lead Dev of Rakudo Perl 6 and founder&architect of MoarVM (appearing via tape delay)

“Parallelism and concurrency are different, though often confused. Asynchrony adds yet another concept into the mix. And there are dozens of different approaches to working with these concepts. How do we identify what kind of problem we’re dealing with, and pick an approach to solving it?”In this session, I’ll look at a range of different problems - some parallel, some concurrent - and show the approaches that may be taken to solve them. And, since I’ve been working on the Perl 6 parallelism and concurrency features, I’ll show how these solutions look in Perl 6.”

October 13, 2015 “Perl 6 - A Dynamic Language for Mere Mortals” (Perl 6 is almost here: Part 1) - Ovid

This month presents a recorded talk by Ovid (Curtis Poe) with live code examples prepared and demonstrated by Bill Ricker. Ovid describes his talk as, “Perl 6 is a great language, but sometimes the enthusiasts talk about the crazy, scary things you can do with it. In this talk, I discuss how easy it is to really use.”

We’ll have working examples in live Perl6 (Rakudo Perl 6), both copied from the main presentation to play with immediately on our screen, for kibitzing and tinkering, plus some other examples to try.

March 10, 2015 - Net::AMQP::RabbitMQ and RabbitMQ - Mike Stemle, Jr.

Video(youtube) [[file/view/Net__AMQP__RabbitMQ Presentation/543820114/Net__AMQP__RabbitMQ Presentation|Slides]] (pdf)

Mike Stemle, Jr. discusses his experiences at ThinkGeek working on and using Net::AMQP::RabbitMQ, an interface library to RabbitMQ , an open source message broker that implements the Advanced Message Queuing Protocol (AMQP).

Being a Perl Shop is hard sometimes, and as a result you sometimes miss out on some of the super-awesome third party support that other - some would say, weaker (but of course we wouldn’t say that, we’re classy) - languages enjoy. So I had to get my hands dirty. As such, I contributed to the development of the Net::AMQP::RabbitMQ module so that we at ThinkGeek could properly integrate our Perl applications with this MQ server.

RabbitMQ example routing

I will walk you through a very high level of the integration itself, some of the challenges we faced, and how we overcame them. I’ll also go through some of the improvements I’ve made as part of the team of people maintaining the Net::AMQP::RabbitMQ module. BEWARE, however, this talk is not for the squeamish. There will be guts. perlguts, and they’ll be everywhere.

December 9, 2014 - “Stirring the Hive with a Perl Stick : Hadoop and Perl” - Charles Hardin

LOCATION: EIG, 10 Corporate Dr #300, Burlington, MA 01803

Hadoop Hive Logo

Hive provides a SQL-like interface to Hadoop. Perl can interoperate with Hive in a variety of ways, including Hive queries through a Thrift API and the direct incorporation of Perl into map-reduce jobs. The author has taken a few baby steps on this journey and chooses to share the results with his peers.

KEYWORDS: Perl, Hadoop, Hive, Big Data, Thrift, Map-Reduce.

This meeting is being hosted by EIG, Sean and Charles’s employer. (A carpool from MIT and/or Red Line will be available for Car-Free commuters, talk to Bill.)

(If you can’t attend in person, this talk will be broadcast live via Hangouts / YouTube and you can submit questions via IRC or Hangouts Q&A.)

November - Mojo, Moo, DBIC - providing a service bridge to Google Apps API - Sean Quinlan


Talk it will cover using Mojolicious (web framework), Moo (object framework), DBIC (DBIx::Class, most popular ORM for Perl) to implement a service bridge between the Google Apps API at Endurance International, a leading web and email hosting provider.

October - ShellShock CGI and Perl DoS bugs - Bill Ricker

Shellshock bug logo

We will examine the implications for the ShellShock BASH bug for Perl – it’s much wider than just about BASH CGI or even Perl CGI scripts – and also a recently discovered/fixed but comparably long-lurking Perl DoS bug in a core module (Data::Dumper stack smash CVE-2014-4330) and how is it possibly remotely triggerable.

The good news is ShellShocker was slightly over-hyped; unlike Heartbleed, this one does NOT generally affect the Internet of Things. Your Internet-enabled toaster is likely immune. But Windows and Mac are not entirely immune to this Linux bug.

September - Creating And Managing a Private CPAN with Pinto & Stratopan Jeffrey Thalhammer

If you use Perl, then you have probably wrestled with CPAN. Shifting dependencies, incompatible interfaces, and test failures in CPAN modules can suddenly break your application, leaving your team to chase bugs they didn’t create. But managing CPAN modules doesn’t have to be painful. A private CPAN repository gives you a stable platform for making consistent builds and managing upgrades for all your Perl modules.

In this session, you’ll learn how to use Pinto to create a private CPAN and build your applications with the right modules, every time. You’ll learn about the dangers of the public CPAN and how a private CPAN can help mitigate those risks. Finally, we’ll cover some of the newest features of Pinto and show you a few power-user tricks to get your private CPAN up and running quickly.

Stratopan is a startup founded by the speaker that provides “Private CPAN repositories securely hosted in the cloud.” So Pinto is the tool that facilitates creating a private repository, and Stratopan lets you outsource the hosting of that repository.

Jeffrey Ryan Thalhammer is a respected software developer, prolific open source contributor, and tech community leader. Author of Perl::Critic and Pinto, used by thousands of developers. Co-founder of Stratopan and Co-organizer of the San Francisco Perl Mongers. He consults under the brand Imaginative Software Systems.

June - Selenium; Perl 5.20

Two short talks:

Ricky Morse - presents automation of web browsers with Selenium::Remote::Driver.


Selenium “is a test tool that allows you to write automated web application UI tests in any programming language against any HTTP website using any mainstream JavaScript-enabled browser. This module is an implementation of the client for the Remote driver that Selenium provides.” - pod

Bill Ricker demonstrates new features in the recently released Perl 5.20, including List::Util updates.

May - Ricardo Signes’ 1.21 Gigawatts

Ricardo Signes (pre-recorded in NY, with live Q&A via Hangouts)

A collection of the speaker’s lightening talks, in the spirit of a highlight reel. We replayed a recording of Ricardo’s talk to, after which Ricardo joined us by tele-presense for live Q&A .)

Some talks carefully guide the listeners through the entirety of a topic, starting with the basics and ending with the fine details. That’s… not the plan for this talk. Instead, we’re going to see the highlight reel of a bunch of topics that caught my interest over the course of the year: a review of cool (and uncool) changes in Perl, the best modules you’re not using, stupid optimization tricks, tools for handling catastrophic program failure, git scripts you’ll become dependent on, numbers stations, Zork, productivity tools, and who knows what else.

I will stand in place and let lightning talks strike over and over, until I am reduced to cinders.

You get to witness the ordeal, and you might just learn a thing or two.

We had a partially successful experiment with a “Hangout On Air” to broadcast the Q&A portion of this presentation: youtube

And the bio:

Ricardo Signes is the current project manager for Perl 5, a maintainer of the CPAN toolchain, part of the Moose development team, and a frequent contributor of other free code to the CPAN. He likes to talk about code almost as much as he likes to write it. He lives in Bethlehem, Pennsylvania, and works at, where he spends his days trying to cope with the horrors of email.

“at my new job i have created a parser for a very clunky fixed record size format. it took longer than anticipated for various reasons. i have a parser module, some db tables to help in real world stuff, a bunch of one off scripts that did useful stuff. could be interesting to see how such a project is done.

well, it was interesting to me as i was paid for it! a chance to code review my stuff and show some nice slicing (perl slicing) and dicing of data.”

Followup discussion in mailinglist

January, 2014 - Deduplication and some modules

Ricky Morse - a short look at Data::Section and XML::XSLT


A recap panel re the DFW Perl Mongers Deduplication Hackathon

SPEAKERS: Joel Berger, Tommy Butler, Yanick Champoux, Bruce Gray, Tim King


How fast can Perl find duplicate files on a 100 GB file system? That’s the question the Dallas/Fort Worth Perl Monger’s Winter 2013 Deduplication Hackathon set out to answer. There were a diverse range of contest entries, from the expected procedural Perl 5 code to ones that used Moose, MOP, and even one Perl 6 entry.

Tom Metro will moderate a collection of prerecorded and live lightning talks by the contestants. After a brief intro, we’ll hear from Bruce on his 6-line Perl 6 entry, from Tim (live in person) with his comprehensive MOP based solution, from Joel with a classic Perl 5 procedural solution, from Yanick with the officially winning solution built with Moose (yes, the fastest used Moose!), and lastly from the leader and contest organizer Tommy (live via Google Hangout) with his unofficial Moose based solution, that post-contest, was further tuned to beat everyone. Lastly, we’d like to hear from the audience what you’d like to see as the topic of a future hackathon.

If you couldn’t make it to the meeting, you can find most of the materials online.

The original meeting recording.

You’ll find Bruce Gray’s Perl 6 entry discussed at time range 17:29 - 35:30. Joel Berger, who won for lowest memory, fewest lines of code, and best Perl::Critic score, introduces himself at 10:54 - 12:48, and then discusses his code at 1:06:10 - 1:21:01.

Tim, who won for best documentation, most features, and best effort, discusses his code after Bruce, but I don’t have the time index.

In a separate video, Yanick Champoux, the winner for fastest run time, discusses his code.

Tommy Butler, the contest organizer, discussed his unofficial entry towards the end of the first video above. (At the meeting he elaborated on some of the optimizations he added post-contest, leading to a design that beats Yanick by 40 seconds.)

December 10, 2013 - Tim King - Benchmarking Perl6 vs Perl5


November 12 - A new object system for the Perl 5 core. - Stevan Little

In 2011 I started working on a project to improve the object system in Perl 5. I wanted to take elements from Moose, as well as bring in some more elements of the Perl 6 object system. The first version of this work ended up suffocating under its own complexity, but after this year’s YAPC::NA I decided to come back to the project with a fresh perspective and so far work is progressing very well.

In this talk I will walk through several examples of the proposed syntax and feature set as well as discuss some of the underlying implementation details. This will be an interactive talk and audience members are encouraged to ask questions, poke holes in the design and help improve the proposal.

If you missed this talk, you can watch an earlier (and shorter) version courtesy of NY Perl Mongers.

July 9 Inline::Java (Perl and Java, together at last ?)

William Cox and David Larochelle on Using Inline::Java with Perl

This talk is a report on inquiry begun on the mailing list slides @G or slides @H PPTx Blog

Q “There is a question that the slides don’t address which I am curious about – why didn’t you just use Java & Java-based languages?

A. “each had major existing workflow in needed to fetch data only available with java api, other needed algorithm only with java api.”

A. “Exactly. Our ORM is in Perl. :Also, I did in 1 file of Perl what Java would require in 10s. The need to maintain simplicity was important for my group. You have to follow the business requirements laid before you. A lot of my group writes Perl. The rest of engineering writing the customer facing stuff writes in Java. We mainly communicate over a database (read: not realtime). But there is the occasional bleed over from Java land that we have to implement the exact same code on our end as which ships in the product. But our framework is (largely) Perl. So we glue the 2 together. And as engineers,”good enough” is perfect.

Some data points for “good enough:”

  1. I can scan a Maven repo for updates in under an hour

  2. I can apply a in-house algorithm to a directory structure in sub-second time”

You expect your developers to continue working when things go slightly wrong; you should expect your code to continue working when things go slightly wrong. The core message is language neutral. The real-world lessons that contributed to the creation of this presentation come from GSN where we use both Perl and PHP on a daily basis. The presentation itself (see below) has some PHP code snippets in it, but swapping those out for Perl is easy and won’t change the subject matter. Feel free to flip through (using left and right arrow keys). If you think this is something the group can benefit from, let me know and I will start rewriting the code blocks.”

It extends perl’s syntax and includes fully vectorized, multidimensional array handling, plus several paths for device-independent graphics output.”PDL is fast, comparable and often outperforming IDL and MATLAB in real world applications. PDL allows large N-dimensional data sets such as large images, spectra, etc to be stored efficiently and manipulated quickly.”

April 10 - Revisiting the Dread CGI – The Uri

CGI refactored before and after

As many of you have known and seen, Uri Guttman will do code review on the fly with anyone’s code on display at pm meetings. This may seem frivolous or whatever but it is can be useful in many cases. He has a client for his Perl support/training services which entails lots of code and design review and it has proven very valuable to this shop. He has obtained permission to show one CGI script in its before any review state and after much review and refactoring. The author of the script did almost all of the editing and rewriting but for one sub rewrite that Uri did because it was more complex than the author could handle. The script went through 14 revisions and it still isn’t where it should be (that means using a proper template module like Template::Simple) but it is light years from where it was. This talk is being called before/after. You will see some of the worst coding and template practices ever unleashed at a gathering. You will be in shock at the use of globals, the lack of subs, and the redundant everything everywhere. Then the tranquility of the after version will calm your senses, sooth your jangled nerves and show you there really can be order in this chaotic universe. Be prepared for coding hell and heaven! Fun is guaranteed for all!

Tuesday March 3/13 (day before Pi Day )

Scripting Ubuntu in LandscapeFederico Lucifredi

Canonical’s systems management and monitoring tool, Landscape ( has multiple facilities for scripting to the system administrator’ content – facilities that can be used with any of the usual array of scripting language choices. We will take a quick look at scripting the managed clients, then we delve into programming the Landscape API to script automation tasks from the shell, in effect, scripting the server, and how this allows custom integration of multiple tools.

January 11, 2011 - Solving a real cryptogram with Perl - Bill R

Bill Ricker presented Using Perl 5.10 and Perl6 aka Rakudo on a cryptogram.

The cryptogram solved was an actual Civil War military message from the Siege of Vicksburg (arguably the more important victory on July 4, 1863) recently re-discovered in a museum.

The Perl 5.10 and P6/Rakudo demos were previews of September 2011’s BLU Crypotology History vignette.

September 14th, “Rakudo Star - a useful, usable, ’early adopter’s distribution of Perl 6”

“Rumors of my death are greatly exaggerated” – Mark Twain

Curious what the Perl community has been up to lately? Come see Perl 6’s recent preview release.

Since July, Perl Mongers groups around the world are doing demo nights to build and exercise Rakudo Star. Boston.PM’s turn is September 14th, MIT E51-376 7:30pm (refreshments in hallway at 7). {This is the night before BLU’s PGP night, second Tuesday is as late as it gets this month.} We’ll install it and show what it can do. We may discuss what more the final release candidate will do, and if enough non-regulars turn up, we can discuss what’s in 5.12 that’s not in the 5.8.4 or older that’s still on many commercial Unix systems

Announce: Rakudo Star - a useful, usable, “early adopter” distribution of Perl 6
Submitted by pmichaud on Thu, 07/29/2010 - 05:18

On behalf of the Rakudo and Perl 6 development teams, I’m happy to announce the July 2010 release of “Rakudo Star”, a useful and usable distribution of Perl 6.

Rakudo Star is aimed at “early adopters” of Perl 6. We know that it still has some bugs, it is far slower than it ought to be, and there are some advanced pieces of the Perl 6 language specification that aren’t implemented yet. But Rakudo Perl 6 in its current form is also proving to be viable (and fun) for developing applications and exploring a great new language. These “Star” releases are intended to make Perl 6 more widely available to programmers, grow the Perl 6 codebase, and gain additional end-user feedback about the Perl 6 language and Rakudo’s implementation of it.

In the Perl 6 world, we make a distinction between the language (“Perl 6”) and specific implementations of the language such as “Rakudo Perl”. “Rakudo Star” is a distribution that includes release #31 of the Rakudo Perl 6 compiler, version 2.6.0 of the Parrot Virtual Machine, and various modules, documentation, and other resources collected from the Perl 6 community. We plan to make Rakudo Star releases on a monthly schedule, with occasional special releases in response to important bugfixes or changes.

Some of the many cool Perl 6 features that are available in this release of Rakudo Star:

* Perl 6 grammars and regexes
* formal parameter lists and signatures
* metaoperators
* gradual typing
* a powerful object model, including roles and classes
* lazy list evaluation
* multiple dispatch
* smart matching
* junctions and autothreading
* operator overloading (limited forms for now)
* introspection
* currying
* a rich library of builtin operators, functions, and types
* an interactive read-evaluation-print loop
* Unicode at the codepoint level
* resumable exceptions

There are some key features of Perl 6 that Rakudo Star does not yet handle appropriately, although they will appear in upcoming releases. Thus, we do not consider Rakudo Star to be a “Perl 6.0.0” or “1.0” release. …

Sept 8th - Open Street Map and Perl - Shankar Viswanathan & Lars Ahlzen

Tuesday is a day early this week, and the 8th is as early as the Boston Perl Mongers can fall. After the as late as possible Labor Day, this is about pessimal. However we do it anyway. We have our usual room for fall.

Our speakers are Shankar Viswanathan and Lars Ahlzen from the Open Street Map project.

April 1 - Git primer and workshop - Steve Scaffidi

MIT E51-376 back in our home room

My idea is pretty simple - I would like to do a tutorial-style workshop where people can follow along on their laptops to use git and see it in action.

I would cover the following:

March 10 - Embedded Perl with Federico Lucifredi

“I am using Perl glue to put together a cheap and small Linux NAS from the Western Digital MyBook II - there are a bunch of hackers doing this, but I wanted mine to have a certain”detail” and so some scripting here and there was required to make it happen - obviously in Perl.

“It may be too optimistic, and certainly smaller in scale, but the WDMBII is starting to spawn a little community movement similar to the Linksys WRT54G.”

February 10 - Parse::Gnaw - Greg London

“I should have a fairly stable version of Parse::Gnaw by (then).”

January 13, 2009 - “Table Driven Testing” - Uri G

room E51-376 one last time

As seen in Uri’s Sort::Maker

“and i keep saying i will also be covering template::simple’s compiled template features. between that and the table driven testing, i can waste^Wfill up plenty of time.” - uri

September 9 - Easy cryptanalysis with tr, s, and /usr/dict/word - Bill Ricker

Using Perl to solve a simple substitution cipher cryptogram.

First, collect simple word-counts - small repeated and long non-repeated words.

word            Count   length
G                 5   1
B                 4   1
U                 2   1
HJZ              11   3
XGHJ              7   4
HJZIZ             4   5
FIGFWDLHU         2   9
HJGH              4   4
UJLKBPY           2   7
HL                6   2
GRKGTU            2   6

Can we guess which of the 3 one-letter words is possessive ‘S and not a ’real’ word?

perl --dump | ack '(?:(?=\S)\W)?\b\w\b'  --passthru

That makes it pretty obvious which one is only as possessive, preceded by an apostrophe. (There’s a reason professionals didn’t include punctuaion unless it was carefully enciphered also!)

Next, check if any long words are obvious from their pattern (pattern’s own pattern is ABCCDEF or 1233456). pattern words

Finally iterate guessing letter translations, with hints for words that dictionary says are uniquely determined already.

Tarball includes a “how” file with sequence for self demo.

May 8, Tuesday, Tech Meeting

Greg London gave a talk based on his book, Bounty Hunters (Metaphors for Fair Intellectual Property Laws).

The metaphors we use to describe the abstract concept of intellectual works bring along their own set of baggage. The metaphor of “property” automatically invokes the idea of “owner” and “theft” and “pirate”. But some metaphors describe reality better than others. This book introduces the metaphor of authors and inventors as Bounty Hunters. The public offers a bounty to any individual willing to create some as-yet- undiscovered work. Creators provide a “service” in the same vein as a Bounty Hunter provides a service of catching bad guys.

April 10, Tuesday, Tech Meeting

Guillermo Roditi gave talk entitled WebApps using Perl and Reaction: “A showcase of the Reaction MVC system through an example application, Prefab. The Presentation will focus on harnessing emerging technologies (Moose, Catalyst, DBIx::Class) to create a smart framework that allows developers to quickly develop complex, security aware web-based applications. The talk will include no mention of Ajax or Web 2.0 type stuff, instead focusing on the technologies driving the server-side and the methodologies and design decisions behind them.”

Jason McIntosh gave a presentation on Volity: “Volity is an open platform for online multiplayer games. Volity itself is a set of language-independent protocols based on Jabber, but much of its current implementation relies on Perl. There are also libraries on CPAN that let you create new Volity game parlors with Perl.”

Kenneth Graves walked us through his three versions of a Kokuro solver. starting with a simple but inefficient brute force approach and ending with one with optimizations and heuristics to make it nice and speedy.

Bill Ricker showed us his script for solving doublets, aka word ladders.

Making Word ladders or doublets is finding a sequence single letter edits that will transform one word to another where all the intermediate states are also words. E.g., cat=>cot=>dot=>dog and grass=>grabs=>crabs=>cribs=>cries=>cried=>creed=>greed =>green

perl -I. ./ one two

September 25, Monday, Special Tech Meeting

Damian Conway gave his opentalk 2.0 and The DaVinci Codebase talks, (both reprises of his OSCON 2006 and OSCON Europe 2005 keynotes).

opentalk 2.0

In the green pastures of technology trends, Damian Conway leaves no sacred cow un-tipped. This entertaining keynote address, from the 2005 O’Reilly European Open Source Convention, pokes fun at many hot topics for software developers including: software patents, open source, mash ups, online communities, rapid application development, operating system zealotry, and even Joss Whedon’s movies and TV shows.

The DaVinci Codebase

When a dying operating system scrawls his name across its corrupted boot volume, Dr. Damian Conway, an unassuming college professor, is plunged into a deadly race against time to solve a series of impossible riddles. What is the mysterious “Priory of Bios?” And who are their deadly nemeses “Opus Arai?” On the run from the law and stalked by a ghostly pale killer, will he unravel the subtle clues hidden in Leonardo’s most famous source code and reveal to the world the incredible secret encrypted in…the Da Vinci Codebase?

Uri Guttman organized a foil hat contest, so the audience could protect themselves from Damian’s mind-warping influence.

<Damian2006Mementos.html> has more details about this exciting meeting, including a fun video of the judging of the foil hat contest and pictures of the winners.

November 9, Tuesday, Tech Meeting

BU Physics Research Building room 148

Cool Uses for Perl: “Bring a fun script to show.”

Bill Ricker started us off by presenting some scripts he’s written for analyzing and creating cryptograms, interspersed with interesting tidbits from the history of cryptography.

Ronald J Kimball followed with some scripts he’s written for solving cryptograms. We also discussed some of the shortcomings to his brute force approach, particularly the problem of proper nouns. (script)

Tim Kohl then reviewed a short script that finds words whose digital sums add up to 666. (e.g. cat = 3+1+20 = 24) Except it really looks for 111, because it multiplies the digital sum by 6, because that’s what the TV evangelist who inspired this script did. We had fun looking through the words that the script found.

After that people threw out a few questions for discussion. One was a tab-delimited file transposition issue that was then discussed on the list. Another was about recursively copying directories in Perl; the File::NCopy module was suggested.

The pizza and soda were generously sponsored by monger Greg London.
Greg has two books available through his website, <http://www.Greg>: Impatient Perl and Hunger Pangs, a science fiction novel. Greg London also has inevitable options.
