Intro to bash shell programming II

Hello everyone,

Below you will find the details of LAMPsig's February presentation. Sitting might be limited, please RSVP at http://www.meetup.com/LAMPsig/events/48519902/

One of the most popular UNIX shells is bash. At the February meeting of LAMPSIG, we are going to sharpen our bash programming skills, and you are invited. It promises to be a bash you won't want to miss.

Dallas Legan is giving his first presentation for LAMPSIG, an intro to bash shell programming II. This tutorial is recommended for all, with the emphasis on borderline transition from command line to scripting, with plenty of scripting tricks provided for even the diehard bash gurus. Dallas will also point out some differences between bash and ksh. So, bring your pencils and notepads and get ready to learn something.

Kind regards,

Topic:
An Introduction to BASH Scripting

Date & Time:
Saturday, November 19, 2011
1:00 PM - 3:00 PM

Location:
Tom Bradley Youth and Family Center
5213 West Pico Blvd.
Los Angeles, CA 90019

Details:

So you've learned a few Linux commands to get around the system, and unless you explicitly said otherwise during the installation process, you are most likely using the Bourne Again Shell (BASH). BASH offers much more than just typing commands to navigate around the Operating System - almost anything you can do in other basic scripting languages, you can do in BASH. This talk will cover:
- The structure of a BASH script
- Setting and reading variables and arguments
- Loops
- Branches and comparisons
- Piping
- Background Processes
- Output literals
- Commenting out code

This talk will include plenty of examples of useful BASH scripts to automate common database administration tasks. However, these concepts will be applicable to any aspect of system administration as well.

About the speaker:

Solomon Chang is MySQL certified, and works as a senior DBA for Ooyala. He is the former president of LAMPSIG and an evangelist of Open Source.

Intro to SendGrid - Learn how to build out a scalable email infrastructure

Intro to SendGrid - Learn how to avoid the pain of building out a reliable and scalable email infrastructure.

Summary:

Email delivery is a complex and difficult problem, SendGrid makes sure developers never have to deal with that type of pain.
Come learn how easy it is to replace your email sending infrastructure with SendGrid and all of the benefits to you and your customers.
Then, this question becomes less important: What does it cost you if an email does not get delivered to one of your customers?

About Presenter:

Elmer Thomas is a Developer Evangelist at SendGrid.com with experience as a developer and manager. His goal is to take the pain and suffering related to implementing email solutions away from developers so they can focus on realizing their passions through code.

Lambdas in PHP 5.3

What: Lambdas in PHP 5.3
When: Saturday, August 20, 2011 1:00 PM

Where: Tom Bradley Youth and Family Center
5213 West Pico Blvd.
Los Angeles, CA 90019
213-915-4402

This is a Joint meetup between LAPHP and LAMPsig.

PRESENTATION DESCRIPTION

One of PHP5.3's terrific features is the ability to use lambdas. But, wait, didn't we already have that with PHP5? What was create_function() about after all? What is the difference between a lambda and a closure or is there any in PHP? Come and explore with me these and other questions in an adventure to discover the truth about lambdas in PHP. The presentation touches on the origins of the lambda and its implementation in PHP5.3. Far greater emphasis is on live code demonstrations of lambdas (and closures, too!) as well as in-depth discussion about the code.

By Solomon Chang

Python is an interpreted (as opposed to compiled) language created by Guido Van Rossum. Unlike most modern scripting languages, which can trace their heritage to C, Python has a number of unorthodox syntax idiosyncrasies, such as lines of code being terminated by newline characters (most of us are used to semicolons) and discrete blocks of code defined by indentation (most of us are used to putting them in curly braces). Despite these odd-seeming rules, Python is remarkably easy to learn, and flexible enough to accommodate anything between a quick and dirty service script to full blown object oriented projects.

This tutorial will focus on getting started with Python, with all the basics of any scripting language: I/O, loops, control structures. Any remaining time after that will be used for showing you how to do those things most people use a scripting language for: connecting to databases, sending out emails, requesting webpages, and other network operations.
Solomon is a fully certified MySQL DBA and former president of LAMPSIG. He uses Python in building a scalable storage engine for his current company. He spends too much time chasing after the latest geek toys.
