From madcityzen at gmail.com Fri May 5 21:44:11 2017 From: madcityzen at gmail.com (Doug Bell) Date: Fri, 5 May 2017 23:44:11 -0500 Subject: [Chicago-talk] Meeting May 25 - MySQL Database Performance For Developers Message-ID: This month's talk will be about database performance: Let's face it, when it comes to databases, developers and DBAs don't often see eye-to-eye. This talk will help bridge the gap using a common goal, "Database Performance". If you're a developer, you've probably used a query that was performing poorly. Many times the solution is seeking help from a DBA. The DBA performs some magic behind a curtain, and all the sudden the query is running fast. Wouldn't it be nice to take a peek behind the curtain to see the magic being performed? During this talk, we'll discuss several aspects of the database that can affect performance. This includes schema design, indexes, and queries. We'll also look at some real life examples of slow performance and performance solutions. Jeremy Glick is a MySQL Database Engineer at ZipRecruiter. Before that, he worked as a consultant for various technology companies with systems ranging from dozens to hundreds of database servers. Jeremy is also the organizer of the Chicago MySQL Meetup. He holds multiple MySQL certifications and is a RedHat RHCE. RSVP on the Chicago.PM Meetup: https://www.meetup.com/ChicagoPM/events/239773480/ Due to Joel and Doug being at the Perl Toolchain Summit, we have to cancel the Office Hours this month. We'll have Office Hours again next month. Doug Bell madcityzen at gmail.com -------------- next part -------------- An HTML attachment was scrubbed... URL: From andy at petdance.com Fri May 26 08:02:24 2017 From: andy at petdance.com (Andy Lester) Date: Fri, 26 May 2017 10:02:24 -0500 Subject: [Chicago-talk] First new Perl::Critic release in 21 months Message-ID: <36178806-BA2D-471A-83FC-E63069D2C17D@petdance.com> I?ve just released a new developer release of Perl::Critic , the static code analysis tool for Perl, as we work toward its first new release in 21 months. This version of Perl::Critic fixes a few bugs and relies on a new release of the underlying Perl parsing library PPI, which also has had its first new release in a while. This version of Perl::Critic is also ready for the impending release of Perl 5.26, which will no longer include . in @INC by default. I?ve been spending some time working through the issues in the GitHub project , cleaning up what I can and clarifying others. If you?ve never used Perl::Critic to analyze your code base for potential bugs and stylistic improvements, mostly based on Damian Conway?s Perl Best Practices, try it out. [Bug Fixes] * PPI misparsing a module caused an incorrect "Must end with a recognizable true value." This is fixed by upgrading to PPI 1.224. (GH #696, GH #607) * A test would fail under the upcoming Perl 5.26 that omits the current directory from @INC. Thanks, Kent Fredric. * Fixed an invalid test in the RequireBarewordsIncludes test. Thanks, Christian Walde. (GH #751) * If an element contained blank lines then the source "%r" displayed for a violation was wrong. Thanks, Sawyer X. (GH #702, #734) [Dependencies] Perl::Critic now requires PPI 1.224. PPI is the underlying Perl parser on which Perl::Critic is built, and 1.224 introduces many parsing fixes such as: * Fixes for dot-in- at INC. * Parse left side of => as bareword even if it looks like a keyword or op. * $::x now works. * Higher accuracy when deciding whether certain characters are operators or variable type casts (*&% etc.). * Subroutine attributes parsed correctly. [Performance Enhancements] * Sped up BuiltinFunctions::ProhibitUselessTopic ~7%. Thanks, James Raspass. (GH #656) [Documentation] * Fixed incorrect explanation of capture variables in ProhibitCaptureWithoutTest. Thanks, Felipe Gasper. * Fixed incorrect links. Thanks, Glenn Fowler. * Fixed incorrect example for returning a sorted list. Thanks, @daviding58. * Fixed invalid POD. Thanks, Jakub Wilk. (GH #735) * Updated docs on ProhibitYadaOperator. Thanks, Stuart A Johnston. (GH #662) * Removed all the references to the old mailing list and code repository at tigris.org.
