Lan will be giving a preview of her SCaLE 16x talk on AWK. Any feedback will be extremely helpful. We'll also be talking about SCaLE, volunteering for SCaLE, and plans for our booth at SCaLE.
Jess will present a brief explanation of the theory behind the Meltdown and Spectre security vulnerabilities that have been in all the news lately.
Dinner begins around 7pm and the presentation will start after most people have received their food or 8pm, whichever comes first. Buying dinner is optional.
Practical AWK - AWKwardly Dealing with Data
AWK is a text processing programming language developed at Bell Labs in the 1970s. It was originally used for data extraction and reporting. It inspired the creation of Perl and can, for the most part, be replaced by Python. It is still incredibly useful on the Linux command-line, both for one-liners or for short, powerful scripts.
Most people have used AWK in one way or another, but they use it without understanding the language. AWK syntax can seem strange. But once you understand that it is a data-driven pattern action language where the data is automatically parsed into predefined variables, it becomes a powerful and intuitive tool.
This talk seeks to take the mystery out of AWK by giving a quick introduction to the language and its features. There will be examples where it provides functionality that a dedicated utility like grep or cut or head might not. There will also be more complex examples where a few lines of AWK result in useful summarization of large amounts of raw data.
AWK is a great Swiss Army knife if you spend a lot of time on the command-line.

About the SGVLUG
SGVLUG is one of the oldest and most active Linux User Groups in the Greater Los Angeles area. In addition to Linux, the group also shares interests in other free and open source software, all forms of technology, and the discussion of issues that arise with the these new tools, such as privacy rights. SGVLUG attracts members from throughout LA County including Pasadena, Glendale, Burbank, and eastward throughout the San Gabriel Valley. Our members include software developers, system administrators, hardware engineers, and software users of all levels of experience. Many work in the technology field as employees, contractors or consultants, and enjoy the learning and networking opportunities available from the group. We also have many members that serve as volunteers of their time and skills at various local events, including the annual Southern California Linux Expo (SCaLE).
