The Portland Linux/Unix Group Advanced Topics meeting

Recoupling Computer Science and Computing

A talk and roundtable discussion

There is no question that hybrid telecommunication/computing appliances like those running iOS and Android have put more open source software into the hands of users than any other effort to date but vendors and carriers consistently choose user control over user freedom. While many users and vendors will argue that "people want their systems to 'just work'", intentional and unintentional decoupling of the user computing experiences from the underlying computer science is the norm, despite the fact that developers and systems administrators are equally lazy and "want their systems to 'just work'".

Because no technical barrier exists between these two experiences of a given system, this talk will explore the historic and modern systems that provide the best balance of user and developer experience and open up to a roundtable discussion of other such systems and how to bridge these two experiences and foster computer science in society.

Please be prepared to talk about your experiences, particularly on platforms like Android and web frameworks which can offer full-stack access to sources yet deliver a competitive user experience.

See you there!

Many will break for the Lucky Lab on Hawthorne afterwards.

SQL change management is hard. Most “migration”-style implementations require opaque naming conventions, prefer DSLs that cover a fraction of SQL, and require duplication of code for simple changes to existing functions. Such does not have to be. And now it’s not

Introducing Sqitch, simple SQL change management that doesn’t suck. Sqitch doesn’t care what programming language your app is written in. It has no opinions as to what database to use or what its schema should look like. And it doesn’t require sequentially-named migration scripts or the use of any DSL other than SQL. Sqitch lets you to write SQL migration scripts that target your database, and provides a simple, unintrusive interface for specifying dependencies, so that it can run things in the proper order.

So come to this talk to learn all about Sqitch: How it works, where to get it, and how to get the most out of managing database deployments.

Embedded GNU/Linux and GPL compliance. How not to make a mess of things by Beth Flanagan of Intel

As GNU/Linux becomes more and more common in the consumer device market, the number of GPL violations found by various compliance organizations have increased dramatically. We'll discuss how violations occur, what to do if you find yourself in violation and how the Yocto Project and OpenEmbedded-Core helps you to avoid a costly GPL violation action.

Beth 'pidge' Flanagan is the maintainer of the licensing infrastructure for the Yocto Project and OpenEmbedded-Core, maintainer of the yocto-autobuilder and build and release engineer for the Yocto Project. She has spoken on a wide range of topics over the years, from GPL compliance in the embedded world to open source firearms.

Ian...

➜ will cover what it's like for n00bs learning how to create a new Perl module, including:

• Where rookies look for "Getting Started" information
• Which tools we can readily find for the job
• What kinds of questions we have about namespaces

What Ian would like to do to help:

• Listen to your answers
• Format them into some kind of guide (or supplement an existing one)
• Hand it to a Perl expert to post in the right place
• Commit to checking in a couple of times a year to keep the information current

You will be vastly enlightened, or horrified.

Joshua...

➜ will continue down the Dist::Zilla path of Automated Enlightenment and speak on Pod::Weaver.

In July, Duke Leto gave Portland an introduction to Dist::Zilla, demonstrating how it can help write, package, test, and release your modules; automating the boring stuff like figuring out prerequisites, automatically inserting and updating $VERSION's, getting rid of all those meta files and generating them automatically; all good ways to focus on the important stuff: the code.

This month, Joshua will show how Pod::Weaver can help automate the boring parts of writing documentation so you can avoid getting bogged down by boilerplate and focus on the important stuff there: the docs.

As always, the meeting will be followed by social hour at the Lucky Lab.

Linux has been used for network routing for many years, but the interface is different than the standard network appliances. Vyatta is a Debian based distribution that provides an open command line interface that looks like Cisco or Juniper. The command line is built on top of standard bash shell with extensible template language.

This talk will go into the history of Vyatta, where it came from and how it is used today. For those who want to contribute or modify, it will also cover the internals of how this implemented.

Stephen Hemminger is a software engineer working remotely in Portland for Vyatta. He has been involved with Linux networking for 8 years and currently maintains bridging and routing utilities. Steve regularly presents at Linux conferences.

The Linux Clinic meets once a month on the third Sunday from 1 - 5 pm at Free Geek, 1731 SE 10th Avenue, Portland, 97214.

Bring you Linux computer that is being a brat and we'll teach it some manners. Or bring your computer that has some evil operating system on it and we'll send it home with a shiny, clean Linux distro. Or just come and look over shoulders to see what Linux is all about.

If you already know Linux well, the Clinic is also a good place to learn how to help users troubleshoot problems. It's excellent training for tech support work in Linux.

We have monitors, mice, keyboards, and miscellanous other perifpherals, so generally all you need to bring is the box.

There is also coffee and people usually bring munchies as well. After all, you can't computer on an empty tummy.

speakers: Eric Wilhelm + Jonathan "Duke" Leto

(Rumored cameo / lightning talk by Florian "rafl" Ragwitz.)

Programming in the Future - a preview of the upcoming OSCON presentation covering the last and next 25 years of programming technology using Perl as our time machine. We'll look at the evolution of tools, syntax, modules, and standard practices, the gooey innards, and some "hot new things" which are still being discovered again.

Introduction to Dist::Zilla for Newbies - eliminates your excuses for not learning more about Dist::Zilla and using it on a regular basis. By the end of this talk, you will know how and why to use dzil as your favorite Perl package developer tool, and you might even need to publish more code on the CPAN just to have an excuse to use it more.

As usual, the meeting will be followed by social hour at the Lucky Lab Brew Pub.

An Introduction to Verilog Synthesis by Galen Seitz

This talk will introduce you to the joys and pitfalls of programmable logic design using Verilog. The focus will be on small designs that could conceivably be undertaken by hobbyists. While we could easily spend weeks on the subject, we will try to cram the following into an hour and a half or so:

• Overview of PALs, CPLDs, and FPGAs
• Why use programmable logic
• Verilog constructs for synthesis
• Synthesis workflow
• Simulation
• Guidelines for synthesis
• A demonstration

If your digital logic skills are a bit rusty, you may want to brush up on your understanding of logic gates and D flip-flops ahead of time. There are many sources of info on the net. Here are couple that may be useful:

This informal panel / round-table discussion will review and demonstrate what has changed over the last few years since Plack has become the leading deployment/glue technology for Perl web applications.

While Plack/PSGI is a vastly more flexible, maintainable, deployable, and scalable model than CGI, in many ways it is a back-to-basics simplification of the ways in which code and servers interact. It has also led to new web frameworks which allow you to forget about all of those fundamental details. We'll try to look at the overall picture, plus specific examples and discuss use cases and migration experiences.

Panel members:

• Ben: Dancer demo
• Joshua: a second person to answer Dancer questions
• Clay: CGI to Plack conversion
• Eric: server options for testing and deployment

The new CPAN module named Voting::VoteFairRanking yields higher levels of voting fairness. You do voting when you click on Google results, and you use voting results when you view the star rating of an Amazon product.

Now learn how voting really works, how it is usually miscalculated – intentionally in the case of elections – and how it can be done to fully extract the wisdom in a group. Learn the math behind the puppet strings that connect politicians (of both parties) to the biggest campaign contributors. (Partial spoiler: The biggest unfairness is hidden in primary elections.) Also learn the math that eventually will cut those puppet strings. Along the way you will learn that there are different kinds of popularity.

As usual, the meeting will be followed by social hour at the Lucky Lab.

The Ubuntu Global Jam is an incredible opportunity for the Ubuntu community to unite together around the weekend of 2nd - 4th March 2012 to work together to improve Ubuntu. Everyone is able to contribute to the Jam, and everyone is welcome and encouraged to get involved. Curious about how to make a real difference to Ubuntu? This is a great chance to make that difference.

Hands-on FreeNAS 64-bit by Michael Dexter

Last month we discussed the history of FreeNAS as a BSD project and the issues related to running FreeNAS on 32-bit repurposed hardware. We toured its user interface and explored its status information from a system administrator's perspective.

This month we will look at this issues relating to building your own 64-bit new hardware system and explore ZFS resource usage.

As before, you are welcome to bring various client machines to interrogate and hopefully pound on FreeNAS with.

Bring your own food and drink.

See you there!

Refactoring is something many developers approach with a great deal of fear. Sometimes you may need to refactor code that you do not understand. Sometimes there are no unit tests. Sometimes things can be scary.

Chad will be showing techniques for cleaning/refactoring code that will help avoid errors, and make things less scary. Ideally people will bring small/medium code samples or modules as examples. If nobody brings anything we may pull something off of cpan.

As usual, the meeting will be followed by social hour at the Lucky Lab.

Acmeism (http://acmeism.org) is the ability to think about and express one's creative ideas, beyond language borders. In programming, this means creating things that benefit multiple languages and communities. Perl is effectively one great community with 2 great languages (Perl 5 and Perl 6). Acmeism is essential to mongers, but kindly extends to pythonistas, brigadiers and nodelings as well.

Pegex is an Acmeist parsing language. Think of it as Perl 6 Rules and Regexp::Grammars for all programmers. Write One Grammar, Parse Everywhere. This makes Pegex the quintessential tool in the Acmeist's belt. Pegex.pm is fully functional in Perl 5, and working it's way across the Acmeist landscape. Come see Ingy döt Net (an inventor of YAML and the father of Acmeism) talk about Pegex and the exciting future of Acmeism.

speaker: Chad 'Exodist' Granum

The DCI concept was created by Trygve Reenskaug, (inventor of MVC) and James Coplien.

DCI Stands for Data, Context, Interactions. It was created to solve the problem of unpredictable emergent behavior in networks of interacting objects. This problem shows itself in complex OOP projects, most commonly in projects with deep polymorphism. This is a problem that Procedural/Imperative Programming does not have.

DCI does not replace OOP, instead it augments it with lessons learned from looking back at Procedural Programming. It defines a way to encapsulate use cases into a single place. This provides an advantage to the programmer by reducing the number of interactions that need to be tracked. Another advantage is the reduction of side-effects between contexts.

Another way to look at it is that a DCI implementation is much more maintainable as a project matures. Changes to requirements and additional features cause clean OOP project to degrade into spaghetti. DCI on the other hand maintains code clarity under changing requirements.

You will Learn:

• How to think in DCI
• How the DCI cpan package helps you write DCI
• That you may already write things in a form of DCI
• How a DCI implementation compares to an OOP implementation (in a generic task)

As usual, the meeting will be followed by social hour at the Lucky Lab.

Shebangml is a markup language which saves programmers from gouging their eyes out on pointy angle brackets.

Most pointy ML data (SGML/XML/XHTML/HTML) can be translated to and from this human-readable, bacony syntax. This allows modern programmers to interface with legacy software such as WWW browsers and other relics like "Enterprise Java Software". But the true power of shebangml lies in the '#!' (hash-bang/shebang) and its programmable templating features. Unlike most "don't make me write HTML" generators and markup replacements, hbml preserves the good parts of the quoting constructs and attributes+content nature of XML. This makes it not only a fine replacement for obsolete markup languages, but also an ideal foundation for new dialects and applications. The pluggable syntax and interpreter allow you to define static or dynamically loadable constructs, which allows your application to balance convenience features with security issues using clear separations.

This presentation will cover the Shebangml syntax, the basics of the parser/interpreter module, the extensions API, and two real-world applications (the FreeTUIT declarative GUI toolkit and the presentation generator Text::Slidez.)

As usual, the meeting will be followed by social hour at the Lucky Lab.

This month's meeting will be a roundtable discussion about modern web serving.

The CGI.pl/ODBC era gave way to LAMP and we're now onto the next generation:

• node.js and NoSQL make LAMP overkill for many situations

• AJAX/JavaScript are moving much application logic to the browser

• Apache is giving way to lighttpd, node.js, nginx and others

• We've gone from 9" Mac support to 1024 X 768 and now to 4" phones

• URL Shorteners. Who would have thought?

• Users now routinely block ads, scripting and Flash

• Apple has declared war on Flash!

• HTML 5 and CSS 3 are starting to appear in the wild

• Security is finally coming first, not last

How have these factors changed the way you serve web content?

Are the fundamental problems being solved and making your job easier?

Please share your experiences at this roundtable and bring your questions.

So you've solved a common problem in PostgreSQL, a serious pain point that lots of other people could take advantage of. You want to open-source the code, and would like to package it up and distribute it where people can find it, read its docs, and download and install it.

The newest destination for distributing PostgreSQL extensions is PGXN, the PostgreSQL Extension network. PGXN offers a central index of PostgreSQL extensions and their documentation, making it easy for people to find an install extensions.

How do you optimize your extension distribution for maximum PGXN exposure? By careful packaging, thorough documentation, and simple installation. Join me for an overview of how best to achieve that — including how to build extensions compatible with PostgreSQL 9.1's improved extension support.

David Wheeler is an associate at PGExperts, and is responsible for PGXN, the PostgreSQL Extension Network) and pgTAP. He's into testing and extension distribution.

IPv6 Networking with Ted Mittelstaedt: Part 1

The first in a multi-part series on IPv6 networking by Ted Mittelstaedt, the author of The FreeBSD Corporate Networker's Guide.

Part 1: Theory & management & ISP routing, as well as current events in the IPv6 realm. For example, did you know that Nortel just sold Microsoft a huge chunk of IPv4 legacy addresses for something like 7 million dollars? This has really turned the tables on the game. Up until that happened the thought in the community was that the large ISP's would be the biggest pushers of IPv6 deployment. But this is an early indicator of what's going to happen. The large ISPs are going to spend millions in vacuuming every scrap of IPv4 out of all the corners on the Internet before they will start pushing their users to go to IPv6. That is a serious problem for any small ISP that does not have a stock of IPv4 because they will be run out of numbers and new customers will not be interested in their IPv6 offerings as long as the large ISPs still are handing IPv4 out.

Selena Deckelmann will be talking about managing terabyte instances of PostgreSQL.

This will be a preview of her MySQL Users Conference talk:

http://en.oreilly.com/mysql2011/public/schedule/detail/17195

Size can creep up on you. Some day you may wake up to a multi-terabyte Postgres system handling over 3000 tps staring you down. Learn the best ways to manage these systems as they grow, and find out what new features in 9.0 have made life easier for administrators and application developers working with big data.

This talk will lead you through solutions to problems Postgres faces when it gets big: backups, transaction wraparound, bloat, huge catalogs and upgrades. You need to monitor the right things, find the gems in DBA-friendly database functions and catalog tables, and know the right places to look to spot problems early. We’ll also go over monitoring best practices and open source tools to get the job done.

Working with multiple versions of Postgres back to version 8.2 will be included, and as well as tips on making the most out of new features in 9.0. War stories will be taken from real-world work with Emma, an email marketing company with a few large databases.

February PLUG Advanced Topics

BSD (Berkley Software Distribution): Enterprise Open Source From Day One

W&W: Tuesday, February 15th, 7PM at Free Geek, 1731 SE 10th Ave

Synopsis:

You use BSD software every day.

Virtually every packet you send travels through BSD-based routers.

BSD gave us the Internet, which gave us Linux and the FLOSS revolution.

The iPhone contains BSD software. OpenSSH is a BSD project.

Michael Dexter of BSD Fund will give a tour of how BSD is being used and discuss why it happily lurks in the shadows of open source. BSD myths will be addressed along with an open discussion of what the audience is doing with BSD.

The plan is to have a series of Lighting talks around the topic of "Worst Useful Hack".

Though our only scheduled speaker has come down with the sick so it might just end up being social hour... though if you have any ideas you would like to share please feel free to bring them up on the mailing list or on irc.

The monthly meeting of the Portland Perl Mongers

peaker: Chad Granum

Chad will give 2 shorter talks in a row. The first talk will deal with lists, what they are, how to use them. The second talk is a short presentation on several useful tools/utilities that started as part of the Fennec project but have been pulled out for general use.

Practical Lists Chad will define what a list is and how it differs from an array. He will cover tools such as grep and map, as well as some List::Util functions. He will explain how you may start using lists in more places when you understand how they work.

Utilities pulled from Fennec Fennec was a large undertaking, it also required implementing a few new ideas. Many of the new ideas are useful outside of the Fennec project. Chad will cover the following until he runs out of time:

Exporter::Declare Method::Workflow Child Exodist::Util Devel::CallerStack

After the Roots Closure and August Dog Days of Summer, it's time for the Portland Linux/Unix Group to beta test a new location and date: Free Geek on the third TUESDAY of the month as opposed to Wednesday.

Having watched two venues go bankrupt, we will try a new strategy: beverages (including the correct one) and Pizza will be served and a donation requested.

Topic: Open Discussion about venues and Tim's presentation on the AIDE Tripwire alternative.

Location-based services are all the rage these days, and almost everyone has a latitude and longitude or two stashed away in a numeric column somewhere. But, there is so much more to it than just a point. Once relegated to government and academia, geographic information systems are becoming increasingly visible. With the PostGIS extension, PostgreSQL is a first-class geodatabase and an incredible platform for working with spatial data, but what is PostGIS and why would one use it? And beyond PostGIS there are a dizzying array of tools to load, visualize and interact with the wonderful geospatial information in your database. This talk will cover GIS and PostGIS basics and provide an introduction to geodatabases and spatial queries.

--

Edwin Knuth spent quite some time as a sysadmin and web developer before going back to school to study Environmental Science at the University of Alaska Southeast. He quickly became fascinated with Geographic Information Systems and realized that GIS was just a really neat database application. In Alaska, Edwin worked on several unique projects, including building bat detectors and using PostGIS to manage a wireless sensor network on the Juneau Icefield. He has lived in Portland for the past year and loves it very much.

Then a trip to the Lucky Lab after.

speakers: chromatic and Michael Schwern

This meeting will be two shorter presentations back-to-back. The Modern Perl talk is broadly targetted at beginners and everyday general usage concepts while the Test::Builder 2 talk will delve much deeper into particular details of Perl's testing system.

chromatic on Modern Perl Perl masters talk about strange subjects such as whipupitude, manipulexity, context, lexicals, and linguistic principles. It may seem that you must be a wizard to apply these notions to your code and dexterously wield Perl's essential strengths. In truth, these ideas and idioms are deceptively simple: you use them every day when you read or write plain English. Demystifying the linguistic concepts in Perl opens up the doors of Perl mastery. Come learn the philosophy behind Perl's design in order to understand Perl and how to use its unique isms to improve your code.

Schwern on Test::Builder2 Test::Builder is what most Test modules are written with these days. It lets them quietly coordinate with each other and frees the authors from having to worry about the details. It was written in 2001 and in that decade there's been an explosion of testing modules. A decade later, Test::Builder is starting to show its age and limitations. Its assumptions and biases are restraining the Perl testing community. Perl has moved on, too. When Test::Builder was written, testing was still a "new" thing. Now it's a given. We have a real object system now and a sophisticated community to take advantage. Enter Test::Builder2. A total rewrite of Test::Builder to remove its biases and let test authors do whatever they can dream up while still being the solid iron core of Perl testing and remaining compatible with Test::Builder. It takes advantage of things like Mouse (that's a small Moose), method wrappers and roles. Counter-intuitively, it does less than Test::Builder does while providing more opportunities. Schwern has a grant for Test::Builder2 from the Perl Foundation and if he doesn't release something by October they'll break his legs. So he's hoping to generate some contributors by showing off the design and code!

As always, the meeting will be followed by social hour at the Lucky Lab.

Jonathan Leto will be talking about "PL/Parrot and PL/Perl6 - Parrots and Butterflies in your Database".

Beer afterwards at the SE Lucky Lab.

Panel: Selena Deckelmann, Igal Koshevoy, Jeff Lavallee, David Wheeler

This will be a panel discussion about the ups, downs, ins, and outs of relational, row, key-value, and hierarchical data stores (simplistic buzzwordiness: SQL vs NOSQL aka ACID CRUD.)

The panel will discuss parallelism, scale, data integrity, normalization, business logic, ORMs, and performance. Some of the following might be addressed:

• why do you want a relational DB?
• why do you not want a relational DB?
• Membase, MongoDB, Redis, Cassandra
• Tokyo Tyrant, CouchDB, old school K/V (zodb, bdb)
• distinctions between "relational" and "row store"
• how filesystem settings affect the database
• how important is your data?
• common errors in SQL schemas or usage
• is count(*) supposed to be fast?
• efficiency vs speed vs parallel cleverness
• sharding
• what is "scale" and do you need it?
• massively denormalized, or massively normalized?
• ORMs, materialized views, indexes, and the query planner
• typical performance with small/large, simple/complex data sets

As always, the meeting will be followed by social hour at the Lucky Lab.

Brian Kurle will be giving a talk about his experiences on architecting and developing a middleware system for Decagon Devices that collects data from remote devices via GSM and provides aggregated data via the web to users with PostgreSQL as the central database.

Looking forward to seeing everyone there....and of course, drinks at the Lucky Lab (http://www.luckylab.com/ ) at 915 SE Hawthorne Blvd. afterward.

The Rakudo * release of Perl 6 on Parrot is almost here. Whether you want to get your own feet wet, or help wetten someone else's feet, join us to write some Perl 6 code and share some learning.

We'll begin with introductions, cover some basics, and then work in small groups or pairs for about an hour, followed by a recap, then (of course) beer.

If you can bring a laptop, download and install rakudo ahead of time:

$ git clone git://github.com/rakudo/rakudo.git $ cd rakudo $ perl Configure.pl --gen-parrot $ make $ make install $ PATH=$PWD/parrot_install/bin/:$PATH $ perl6 -e 'say "Hello World"'

Drinks afterward at the SE Lucky Lab.

speaker: Ingy döt Net

Ingy will give a talk about:

• Acmeism - Programming above programming languages
• C'Dent - A portable module programming language
• Stardoc - An Acmeist documentation system
• TestML - An Acmeist unit test language

Imagine writing a Perl module, and then uploading it to RubyGems and PyPi and a dozen other language repositories as a native module for that language. C'Dent compiles modules Perl, Python, Ruby and JavaScript modules to many languages. Stardoc reformats POD to many other formats. TestML lets you write one set of tests that all the compiled modules must pass before shipping.

This is the future. This is Acmeism.

When: 7pm Thursday, May 20 Where: FreeGeek Who: Melissa Hollingsworth What: Normalization!

Drinks afterward at the SE Lucky Lab.

speaker: Chad 'Exodist' Granum

Chad will demonstrate what he has so far, and request feedback.

From the fennec docs: Fennec - Framework upon which inter-compatible testing solutions can be built.

Fennec provides a solid base that is highly extendable. It allows for the writing of custom nestable workflows (like RSPEC), Custom Asserts (like Test::Exception), Custom output handlers (Alternatives to TAP), Custom file types, and custom result passing (collectors). In Fennec all test files are objects. Fennec also solves the forking problem, that's it, forking just plain works.

This framework is what has come from a discussion around modern testing in Perl. It is an attempt to address, or make addressable the desires and needs expressed therein. It is also an attempt to make glue for all future solutions to current and future problems.

As always, the meeting will be followed by social hour at the Lucky Lab.

Tim Bruce will be speaking at the next PDXPUG meeting at FreeGeek (at 7:00pm - 1731 SE 10th Avenue, Portland, OR).

An Introduction to Managing and Troubleshooting PostgreSQL on Windows

This talk will be for entry-level to mid-level Windows Administrators who have to support PostgreSQL on Windows (Windows Server or Windows Desktops). I'll touch on managing the service(s) and checking the Windows logs, as well as some quick ways to look for performance of the Operating System and PostgreSQL with the built-in tools on Microsoft Windows.

Tim Bruce is a Database Administrator for Fiserv Enterprise Technology. He is spread between Microsoft SQL Server on Windows and PostgreSQL running on SuSE Linux. In his spare time, he supports several Emergency Service organizations including the Washington County Composite Squadron of the Civil Air Patrol.

Looking forward to seeing everyone there....and of course, drinks at the Lucky Lab (http://www.luckylab.com/ ) at 915 SE Hawthorne Blvd. afterward.

speaker: Robert Buels

Rob will give an introduction to and overview of DBIx::Class. It's an object-relational mapping framework, much better than the old Class::DBI, and it will make your life easier if you are currently writing a lot of SQL in your Perl.

As always, the meeting will be followed by social hour at the Lucky Lab.

How to learn to parse huge XML documents by doing it wrong for 5 years speaker: Tyler Riddle

When XML documents can't fit into memory the vast majority of solutions available on CPAN are no longer available to you; when the XML documents are so large they take up to 16 hours to process with the standard tools for handling large documents your hands are tied even more. Tyler will cover his learning experiences creating the Parse::MediaWikiDump and MediaWiki::DumpFile modules which are made to handle the 24 gigabyte English Wikipedia dump files in a reasonable time frame.

1) Real world benchmarks of C and perl libraries used to process huge

XML documents. 

2) The dirty little secret about XS and what it means for you in this

context. 

3) The evolution of the implementation of a nice interface around event

oriented (SAX style) XML parsing. 

4) Why XML::LibXML::Reader and XML::CompactTree are your friends and

how to tame them.

As always, the meeting will be followed by social hour at the Lucky Lab.

Over Normalization from a developers point of view.

Ben Hengst works for Powells.com and has been involved in some in house restructuring, mostly centered around moving to a very vertical structure. This talk will revolve around what works and what doesn't, code and people problems that have been encountered and how to dig your self out.

Looking forward to seeing everyone there....and of course, drinks at the Lucky Lab (http://www.luckylab.com/ ) at 915 SE Hawthorne Blvd. afterwards.

speaker: Jonathan Leto

Come learn the basic things you need to know about Parrot Virtual Machine to start hacking on

1) Parrot VM itself 2) Languages built on top of Parrot, High Level Languages (HLLs) 3) Projects and Libraries that use Parrot

A short, down-to-earth introduction to the current state of Parrot will be followed by examples on how to hack on Parrot projects or how to start your own.

As always, the meeting will be followed by social hour at the Lucky Lab.

The Portland PostgreSQL Users Group (PDXPUG)

John Naylor will be talking about his experience in Florida as a data manager for President Obama's 2008 campaign. He will discuss the role of data in political campaigns, and also refactor some data warehouse queries. Donuts and bacon provided.

Refreshments will be partaken at the Lucky Labrador Pub in SE Portland afterward.

How to Lie Like a Geek speaker: Michael Schwern

Geeks have a special relationship with The Truth. Nothing is more important than correcting a falsehood, no matter how small, and nothing is more odious than not telling The Truth. Unfortunately, in speaking The Whole Truth and Nothing But The Truth, the meaning is often mangled and the end result is the opposite, a lie.

We’ll examine some ways geeks lie while telling The Truth, to themselves and to others, and hopefully achieve better communications, easier to understand interfaces and maybe some personal enlightenment.

Some examples include: Lies by omission, lies by precision, lies by irrelevancy, lies by design, lies with statistics and that most dangerous of words “should” as in “the user should have realized”.

You have an idea for some program that you've always said you would write when you got a round tuit. FreeTUIT gives you that first tuit for free. Now you can write a simple cross-platform desktop application without writing any code. Just declare the widget layout and put a shebang line on it and you have an executable application. From there, it's a simple matter of programming to respond to input events.

FreeTUIT is a syntax and Perl runtime for concisely declaring the layout and configuration of GUI widgets (such as forms, toolbars, buttons, and dialogs). The freetuit interpreter drives a unified object layer which is accessible from event callbacks. The system is currently built on top of the wxWidgets toolkit, and is currently in transition to the Qt widget set.

More details from Webb:

If anyone is wondering about specifics, I will describe how I recently created a "crosswalk" table that correlates census tracts in 1980 with census tracts in 2000 in the Portland region (well, Washington, Multnomah, and Clackamas counties), so that we could see poverty trends over the last 25 years.

I used PostGIS, Census naming conventions ("FIPS codes"), and lots of outer joins. So if you like that sort of thing, I would love to hear your comments tomorrow!

by Len Shapiro

Abstract: I'll survey how I teach the introductory database course at PSU. My goal for the talk is to elicit suggestions for how I could do a better job. The theme of the course is "transforming data into Information". I use a 200 Meg database, hosted on PostgreSQL, instead of the one-slide databases used in typical intro courses, to illustrate the principles of the course. The database is Federal Elections Commission data re donations to candidates, so queries often reflect real questions about the real data.

Bio: Len Shapiro has been a professor at PSU for 23 years. His research interests are primarily in query processing.

PDX.pm meetings are on the second Wednesday of each month at 6:53pm, typically at Free Geek. Meetings are free-of-charge for all PortlandPerlMongerMembers. The cost for non-members is $2,000,000,000.00 per person.

What tools and techniques do you use to keep your project shiny and well-oiled? Bring a sample for show-and-tell, or just a few things to say about it.

Please see the kwiki link for the latest details about this meeting. Our panels always lead to interesting and surprising discussion.

Chris May will be speaking.

Looking forward to seeing everyone there...and of course, drinks at the Lucky Lab (http://www.luckylab.com/ ) at 915 SE Hawthorne Blvd. afterwards.

Moose is a postmodern object system for Perl 5.

Moose's recent rise in popularity has led to a surge of declarative class-building and accessor-generating modules, but the real power of Moose comes from its metaclass fundamentals, not from the syntactic sugar of has(). Using Moose as a foundation makes it easier for your code to grow and scale.

I'll cover some of the concepts in Moose that the MOP (Meta-Object Protocol) makes possible, especially roles and type constraints. If we have time, I'll go through a simple Moose extension, focusing on the mechanisms Moose provides to help your code play nicely with others'.

If the first sentence of this description was news to you, you should at least read the SYNOPSIS of Moose, and if you can get through Moose::Manual and Moose::Manual::Concepts, so much the better. I'll expect a lot of questions, but I hope to move past "what is an object" pretty quickly. By the end of the night I hope you'll have a better understanding of the depth of what Moose provides, and why has() is only the tip of the iceberg. I don't expect that everyone will immediately understand every concept provided – my goal is to impress you so much with Moose's awesomeness that you're willing to follow up later on the documentation pointers that I throw out.

Monthly meeting of the Portland PostgreSQL Users' Group.

Kristin Tufte will be speaking about the Portland Transportation Archive Listing (PORTAL) database schema.

Beers after at the Lucky Lab on Hawthorne.

Test::Builder underpins 80% of the tests on CPAN. Its limitations become everyone's limitations. It's done a very good job adapting the last seven years, and testing has become more sophisticated in that time, but age and backwards compatibility holds things back. There are a number of desired features which Test::Builder cannot support, such as end-of-test actions, without radically altering how tests are built.

thus: Test::Builder2.

This will be "something of a talk" followed by some hacking both on Test::Builder2 directly and writing new test modules. It'll give folks an opportunity to work both with Moose (well, Mouse) and git. Pair programming will make life easier, we can pair of experienced folks with inexperienced. Or just huddle together for strength in numbers. I find it easier to pair when each person has their own keyboard, so I'm going to bring along a few spare keyboards and mice. I encourage others to do the same.

Monthly meeting of the Portland PostgreSQL Users' Group.

Ed Borasky will be speaking about Data Visualization.

Free Geek is offering a bash scripting class, and I am teaching it. Six tuesdays, starting February 17, from 5:00 to 6:30.

We will start with source file editing and version control, move on to variables, loops, conditionals, functions, input/output, and sqlite over the course of six weeks.

If you want to register, call/ email Free Geek and they will give you the low down.

Although it is technically free, I am asking that all gainfully employed students donate to FG, with $150.00 for all six classes

I started using Perl just over six years ago, when 5.6.2 was already getting old and 5.8.1 was on the way. By the time I put my first module on the CPAN, over half of the current contributors had already shipped.

I have often read the source of a core module and asked "Why?" only to discover some unknown feature or historical accident. The history lesson continues all the way into the roots of Unix in some cases, but also often leaves me thinking "So?". And now I am quickly approaching my 40th CPAN distribution.

In this talk, I will share my own experiences in developing with Perl and explore the idea of the "Modern" or "Enlightened" Perl. Did I miss the heyday of Perl or are we still making that now? How does today's Perl code look different than it did 5 or 10 years ago? Is there a Perl renaissance coming, and what does it have to do with Perl 6? What modules should you be using for new development? Where is my flying car? Why am I still programming in Perl? And why am I programming at all?

I will try to find answers to some of these questions and invite you to bring questions (or answers!) of your own.

As always, the meeting will be followed by social hour at the LuckyLab.

Perl 6, Perl 5, Python, Ruby, Lua, JavaScript, Java, C#, and many other languages use virtual machines as their execution environments. Instead of compiling directly to machine code, they rely on the presence of an ideal machine built specifically for the language – porting the language to a new architecture often means only porting that virtual machine.

Does that sound complicated? It's not. Some of the details of very efficient and effective virtual machines are, but the general ideas are simple.

This talk explains the important components of a virtual machine and how they fit together. Examples will come from the world of Perl 5, Parrot, and Perl 6, but the concepts apply to many languages and VMs.

You may never need to hack the guts of your favorite language, but understanding how they work can help you become a better programmer.

As always, the meeting will be followed by social hour at the LuckyLab.

This will be a guided "hack session" about getting involved with the development of Rakudo, the first fully-featured Perl 6 implementation, which runs on the Parrot Virtual Machine. There will be a briefing at the beginning of the meeting to bring everyone up to speed and clarify any confusing terminology.

Then we will break into groups and learn-by-hacking on whatever interests the participants. You must be interested in doing something with Perl 6/Rakudo, start now!

The end of the meeting will be a short wrap-up where people voice there experiences working on Rakudo (what needs to be made easier? what rocks? what sucks? what do you want to work on next time?).

PDX.pm normally meets at 7-till-7 (6:53pm) at FreeGeek for roughly an hour or so, then walks a few blocks to the Lucky Labrador Brew Pub for social hour.

While many people may know Randal Schwartz of Stonehenge Consulting (http://www.stonehenge.com/) from his talks and papers on Perl, he is also quite knowledgeable about Smalltalk and will be giving a talk on Smalltalk and Postgres integration.

We will be meeting Thursday, November 20th, at FreeGeek at 7:00pm - 1731 SE 10th Avenue, Portland, OR.

Looking forward to seeing everyone there....and of course, drinks at the Lucky Lab (http://www.luckylab.com/ ) at 915 SE Hawthorne Blvd. afterwards.

Wed. November 12th, 6:53pm at FreeGeek -- 1731 SE 10th Ave.

Speaker: Gabrielle Roth Topic: 600 Simple Strategies for Sanely Summarizing Cisco Syslogs

Syslog is a handy troubleshooting tool, but only if you actually read what's logged. I wrote a Cisco syslog parser & reporter as part of our network fault-management system. We'll go over:

• network management basics
• why we needed this specific tool
• why I created my own tool from scratch (instead of using an off-the-shelf solution)
• how I did it & what the results were, and
• what I'm going to do next.

You don't need to be a Cisco engineer or even know much Perl to get something out of this talk.

As always, the meeting will be followed by social hour at the Lucky Lab.

Even though PG Con West will be going on October 10-12 in sunny (hopefully) Portland, we will still have our monthly meeting on October 16, 2008. This month, Selena Deckelmann will provide a tutorial on setting up Point-in-time recovery for your PostgreSQL installation. This will be hands on, with the ever-dangerous LIVE DEMO.

We will be meeting at FreeGeek - 1731 SE 10th Avenue, Portland, OR.

In November, our own Randal Schwartz of Stonehenge Consulting (http://www.stonehenge.com/) will be giving a talk on Smalltalk and Postgres integration.

Looking forward to seeing everyone there....and of course, drinks at the Lucky Lab (http://www.luckylab.com/ ) at 915 SE Hawthorne Blvd. afterwards.

We're relegated to the classroom at freegeek this month, so I figure we should make the best of it and have a perl 6 class.

Jerry Gay will be visiting from Seattle. Jerry is a key contributor to parrot/rakudo and will be very helpful in understanding what rakudo can do right now and diagnosing any troubles that come up.

We will have a short walk-through at the beginning and if a projector is available we can use it to increase the tutorial bandwidth.

Bring a laptop if you have one, preferably with parrot (or even pugs) already setup. If you do not have a laptop or if you would be able to bring more than one, please let me know.

I would like this to be very hands-on learning and I imagine we'll probably be working in pairs or small groups as well as spending some time reading documentation and sharing what we've learned.

If you have some experience with Perl 6 or have been playing with it recently, please share your useful links or insights by posting them on the list or the wiki.

http://pdx.pm.org/kwiki/index.cgi?October2008Meeting

If you have no experience with Perl 6, this is where you get it! Bring your friends. There's still more than one way to do it in Perl 6 and I'm looking forward to seeing where people's interests are. Working through some of the perl quizzes or porting other illustrative examples might be fun for some while others might be interested in playing with the classes and objects, or mod_perl6, etc.

As always, social hour at the lucky lab afterwards.

Third Sunday of the month, we meet at Free Geek to help each other with Linux problems. Bring your computer or laptop. We have power, desk space, wired and wireless ethernet, keyboards and monitors. We have coffee, cookies, and Penguinos, the premier penguin themed Mexican cupcake.

PostgreSQL Users' Group monthly meeting. Followed by refreshments at the Lucky Lab.

Topic: Visual Planner Presenter: Tom Raney, PSU Where: FreeGeek, 1731 SE 10th Avenue, Portland, OR When: 7pm, September 18, 2008

Tom Raney will be presenting the Visual Planner, a GUI tool written in Java that enables the user to peek inside the PostgreSQL planner's decision making process. The tool shows all plans that were evaluated including the plan that was picked for execution. Tom worked on this during Google Summer of Code, and credits Dr. Len Shapiro, a professor at Portland State University and PDXPUG regular, as a great help.

Tom showed off his tool during OSCON and has gotten some feedback from community members on it. He's working up a test example that should appeal to DBAs, and I'll link directly to the source code once he's got it ready.

This work also involves a patch to PostgreSQL, which should be available soon!

After the meeting, retire to the Lucky Lab for refreshments!

Wed. September 10th, 6:53pm at FreeGeek -- 1731 SE 10th Ave.

Speaker: Jonathan Leto Topic: Scientific Computing with Math::GSL

This talk will be an introduction to doing scientific computing with Perl and Math::GSL. This module provides access to functions from the GNU Scientific Library via Perl code.

Why would you want to do that? Using the Perl interpreter's easy and fast I/O, string processing, and managed memory reduces programming time while GSL's optimized numerical library (compiled C) gives you access to a variety of mathematical routines to do the heavy lifting.

http://www.gnu.org/software/gsl/ http://search.cpan.org/dist/Math-GSL/

You do not need to know Perl or bring a lab coat. You should bring your scientist friends (steal their lab coat?) and it helps if you know how to program in some language (FORTRAN anyone?), or something about math.

As always, social hour at the Lucky Lab after the meeting.

On Saturday, August 23, Free Geek will celebrate eight years of operating the Community Technology Center with a Street Party. Geek Fair! is a free event for all ages. Festivities start at 12pm and go until 6pm. Geek Fair will have live music and delicious food & refreshments. There will be tons of fun stuff to check out and lots of kids' activities. The event will be showcasing great local bands. Geek Fair gives the public many fun ways to contribute to the Free Geek cause. There will be a raffle with lots of great items donated from local businesses, and featuring a really nice Linux computer as the grand prize. Free Geek's computer thrift store will be open with some great specials and bargains for the computer hobbyist, or you can take one of the regular tours of the facility that will be offered every hour throughout the day. Geek Fair is sponsored by some of these following local businesses and organizations, Clever Cycles, Zip Car, Cellar Door Coffee, Bear Recycling, Hasson Realtors, New Seasons and Free Geek. Free Geek is a local non-profit organization that recycles and refurbishes donated computers and other electronic equipment, making it available to individuals and non-profits in the community. Volunteers can participate, learn and earn a free computer system in the process. Volunteer orientation tours are held daily at noon and 6pm. In eight years of operation, Free Geek helped more than 15,000 volunteers get their own computer system or learn how to build the computers that are given away through their various programs. Free Geek's recycling program has salvaged over 1,800 tons of e-scrap, keeping toxins such as lead and mercury from the landfill and recovering valuable materials such as gold and copper for reuse.

Come talk about what you did at or near OSCON. Free-form discussion, followed by beer at the Lucky Lab.

If you are arriving early to OSCON, and you have a Linux problem that needs fixing, or you are a wizard who can help others, escape from the pesky sunshine and join us at the monthly Linux Clinic at Free Geek at 1731 S.E. 10th in Portland, about 20 blocks south of the convention center. The main facility is closed, but we have access to the classroom in the southeast corner.

We will have wireless, ethernet, distros, coffee, cookies, and Penguinos, the premier penguin-themed mexican cupcake. We run until 5 PM, though in honor of OSCON we may move proceedings to the Lucky Labrador Brew Pub or Jax Bar, local open source hangouts that serve food and beer.

Topic: Rescue Your Doomed Project

Any large software project struggles with managing code, managing people, and managing expectations. This is especially true for free software projects developed mostly by volunteers. Your project will run into one or more of them. Here’s what can possibly go wrong, how you can make your problems worse… and how to fix them.

Topics include:

* how not to manage volunteers
* how not to promote your project to potential users
* how to avoid releasing software
* how to let bottlenecks derail your plans
* how to reduce the quality of your code
* how to chase away interested volunteers
* how to chase away core contributors
* how to render beautiful documentation useless
* how to ensure that carefully-devised technical plans will go largely ignored
* how to hide important knowledge in inaccessible silos
* how to promote technical contributions over the polish that really matters
* how to maintain features no one knows anything about

... and most importantly, how to identify stupidly simple ways to make users and developers happy, productive, and successful.

As always, the meeting will be followed by social hour at the LuckyLab.

What am I going to do with this big box of Penguinos, the premier penguin-themed mexican cupcake? I know, I will bring them to the Linux Clinic on Sunday! Perhaps we can boot Ubuntu on them!

The Linux Clinic runs from 1 to 5 PM this (third) Sunday, June 15, at Free Geek 1731 SE 10th in Portland. The main facility and the store are closed; we will be in the room on the southeast corner.

Not only will we have penguinos, cookies, coffee, portland punch, and other savory collations, we will have distros, power, wifi, wired ethernet, keyboards, monitors, and much, much more! We will even have answers to your most pressing Linux questions, and some fraction of those answers may be approximately correct!

So bring yourself, your machine, a notebook to write in, and what Linux knowledge you have to the Linux Clinic! We can use helpers as well as helpees; this is your chance to flaunt your knowledge, or just make stuff up!

Come join us for an evening of Pythoneering with Jason Kirtland, a key force behind the Portland Python Interest Group - http://wiki.python.org/moin/PortlandPythonUserGroup. They are having Lightning Talks tomorrow night at Cubespace.

Our own David Wheeler will give a repeat performance of his talk from PostgreSQL Conference West 2007: Ruby on Rails Essentials for PostgreSQL Enthusiasts Has all the hype got you jazzed to develop Ruby on Rails applications on PostgreSQL? Is virtually everything you find about Rails MySQL- specific? Come to this talk to learn all you need to know to make Rails and PostgreSQL work together harmoniously. Topics will likely include: * The ins and outs of Rails migrations * How to add support for foreign key constraints * Managing partial indexes and other PostgreSQL-specific objects * Working with views * Monkey patching for fun and profit * Supporting multi-column primary keys * The joys and pains of Rails collections * Working with time zones * The antiquity of the Ruby PostgreSQL driver (NOT) * Enforcing constraints in Rails and in the database * Getting Rails to execute your queries instead of its own * Saved queries for "fat models"

We're a user group devoted to PostgreSQL - programming, administration and development. Our meetings are on the Third Thursday of the month.
