Logging is one of the most important pieces youâll have in any large-scale software system, and in a massively multiplayer game itâs even more critical. Using Ovidâs Veure MMO as an example, Iâll discuss what we are logging and why, how we use fluentd to collect information at all levels in the gameâs stack, and the tools and processes we use to analyze that data.
This month, Doug Bell will be giving two short talks.
One talk is about using Travis-CI, a free continuous integration testing service, for Perl projects, and maximizing Travis's effectiveness. This talk introduces Graham Knop's Perl Travis Helpers, gets you started using Travis-CI, and shows how to configure Travis to cover edge cases like very old Perls and missing optional modules/features (using Devel::Hide).
The other talk is an introduction to Rex, a Perl-based server configuration management system. This talk was given informally at an office hours last year, but now it's a real talk with real slides! This talk introduces Rex, goes through simple configuration and tasks, and touches on some of the more powerful features of Rex such as the CMDB (Configuration Management Database).
EDIT: Slides are now available for both talks on the Chicago.PM talks page:
This month, William Lindley will be giving a talk on Imager, an image manipulation library for Perl. Easier to install than Image::Magick, Imager has grown into a rich set of tools, including some overlooked features that turn it into a robust solution.
This month, Doug Bell will give a talk on Graphite, a scalable time-series database. He'll go over a quick installation and setup, how to add your metrics using Perl, and how to display your metrics using the Grafana charting dashboard.
We've got a couple short talks scheduled for this month, and we've got a new venue, generously provided by ServerCentral.
Joel Berger is going to give a talk on testing any PSGI application with Test::Mojo, Mojolicious's excellent web testing library.
Due to the holidays, our meeting will be on December 10. RSVP on the Chicago.PM Meetup
(EDIT: Slides from the simple WebSocket tricks talk are now available)
This month Doug Bell will be giving a talk on
Git internals, and how they effect how you use Git
rebase. The presentation
will go over some common errors and explain what they mean, and how
resolving them will affect the internal data of your repository.
This month, Eric Johnson (kablamo) will be giving a talk exploring the Perl testing ecosystem, including how to write tests in Perl, using prove to run tests, TAP (the Test-Anything Protocol), and an exploration of CPAN test libraries including:
This month, Doug Bell, Joel Berger, and Eric Johnson will be giving short demonstrations of tools to manage Perl distributions. A distribution is an installable bundle of modules, usually uploaded to CPAN for others to download.
Doug will be presenting Dist::Zilla, the 500-lb gorilla of dist management. Joel will presenting Module::Build and Module::Build::Tiny with App::ModuleBuildTiny. Finally, Eric will be presenting Minilla and Carton.
Each talk with take about 20 minutes, with some extra time for questions.
Doors open at 6:45. Meeting starts at 7:00. RSVP on the Meetup page
This month, Mike Schienle will talk about reading and writing Excel spreadsheets from Perl, with the main focus on writing them. The presentation will discuss writing both data and formulas, multiple sheets, adding comments, etc. Mike uses Excel in both his day job as an ETL geek for Northern Trust and processing weather data.
Doors open at 6:30pm. Meeting starts at 7:00pm. RSVP for Excel Spreadsheets with Perl on the Chicago.PM Meetup.
This month's office hours will be on June 11. RSVP for office hours on the Chicago.PM Meetup
