This month's meeting we will focus on Process Improvement which will include 4 presentations from Alan Dayley, Joseph Sinclair, and Bryan O'Neal.

Alan Dayley
An experience in Lean Development

The ideas of lean manufacturing have surprising application in the production of software. We will review the principles of Lean Software Development and then experience of taste of their use with often surprising results.

The Essential Principles of Kanban

Kanban is not just putting stickies on a wall. Kanban is not a process but is an improvement management technique for any process. Without the principles, your stickies on the wall might not give you more than just interesting decoration.

About Alan:
After more than 25 years as a software engineer, Alan discovered the thrill of the human side of creative endeavors. He has spent the past seven years helping people re-learn to enjoy working and creating. He has helped many teams and companies embrace new ideas for interaction that produce better results. He continues to cheer FOSS creators and users from the sidelines.

Joseph Sinclair
Why everything you're doing probably doesn't matter

Everyone in the business world wants to improve the business results. As software and software engineering become ever more critical across every area of business, much time and effort is being focused on modern software engineering process and software process improvement (both in development and operations). The Theory of Constraints (ToC), however, highlights the core cognitive gap which results in the majority of software process improvement efforts failing to materially improve results. In this very short introduction we'll cover a few basic premises from ToC and one simple step you can take right now to help capture material business results from your current process improvement efforts.

About Joseph:
Joseph has been working with computers for substantially longer than he'd care to admit, but the first computer he wrote software on had a whopping 16K of RAM.
Joseph first used Unix in 1989, and Linux in 1995. He has spent the last 10 years focused on developing software systems supporting Internet-scale solutions using a wide variety of distributed technologies, including Hadoop, Mesos, Spark, Storm, Riak, HAProxy, LXC, and Docker (among many others).
Joseph has also been a champion of software process improvement culture since the late 1990's, and has led or supported several teams and companies in transition to more effective software engineering processes.

Bryan O'Neal
Principles of Agile Development for beginners

Presentation will go over the philosophy of agile development and provide a quick overview of scrum and kanban methodologies

About Bryan:
MySQL DBA, programmer, and general geek.
Currently working on improving the data systems for the worlds largest authoritative DNS representing ~30% of the worlds domains and one of the worlds largest certificate authority representing ~25% of the worlds PKI.

Due to unforeseen circumstances, we've had a last minute cancellation.

Joe Giron will not be able to make the meeting tomorrow so his presentation on MassScan will be postponed till next month. Thankfully Aaron Jones has volunteered to step in so we still have 2 presentations for our meeting on Thursday.

Aaron Jones: CLI way to do things usually done with a GUI

Aaron is a web developer who enjoys using new technologies. He began using Linux while still a kid and is pro- VIM, GIT, CMUS, and NEWSBEUTER. His workflow is command line based and he hope's to help others learn more about computing, linux ,and the tools out there to make them more productive.

der hans: Anatomy of the Command Line

Order matters when the shell executes a command, but isn't strictly left to right. Redirects, functions, sub-shells, {brace,tilde,parameter,variable,arithmetic} expansion, pipes, globbing, regular expressions, command substitution and more.

What order does bash evaluate the different parts of the command line and what effect does that ordering have on the command? Which portions of the command are evaluated by the shell and which aren't?

The presentation will use command line examples to illustrate evaluation order for the various parts of a command.

For example:

grep foo file.txt >file.txt

That command results in file.txt being empty regardless of what the previous contents were ( provided file permissions allow the user to write to file.txt ). The reason is that the shell truncates file.txt before even starting up grep, so grep is actually searching a newly truncated empty file.

echo -n $( echo foo >>file.txt ) >file.txt

Again there is an empty file at the end even though foo is added to the file.txt during the command. In this case, the command subtitution and it's associated output redirection runs and completes before the outer shell and it's redirection. As a result, file.txt gets a line of input, then is truncated.
