Free Software Stammtisch job networking event this Tuesday at 18:00.

We encourage engineers from groups that are hiring and hiring managers to attend. The goal is for prospective candidates to learn about the company and the actual job while giving the team a chance to meet prospective candidates. Interviews are bi-directional, so are job searches.

We have several confirmed employers this month:

* Early Warning/Zelle - hiring in the dozens
* Recruit Bit Security
* Shutterfly
* Red Hat - always hiring lots of Free Software people
* PayPal

We might also have a couple of companies hiring hundreds of people, USAA and State Farm, and possibly some off-planet work.

If you're looking for a job, this month would be a good time to show up. If you have friends looking, same for them :)

Tuesday, 2018Oct16 @ 18:00
Boulders on Southern
1010 W Southern Ave, Mesa, AZ

You can RSVP via GetTogether.

The next jobs event will be a resume review night in January.

We'll have 3 presentations at this month's meeting, starting off which what we hope to be an infrastructure series, and what is more basic to our infrastructure than the power itself, so Barbara Cenalmor of SRP will be telling us about the nitty gritty of how SRP makes sure that you have all the power you need at the moment you need it. Then der.hans will tell us about better protecting ourselves on the web with uMatrix. Last, but not least Aaron Jones will show us how to better manage our digital fingerprints and to live safer in this world filled with social media .

Barbara Cenalmor: SRP Resource Planning

It’s really easy to take electricity for granted. You hit the ON button, and the computers instantly turn on. However, there are a lot of things that go on behind the scenes to get that electricity to you, the main user.

To keep up with the demand and makes sure everybody can turn on their computers, lights and appliances, utilities use resource plans.

This presentation explains what resource plans are, why they are important and needed, what resource options are available to utilities, what the trade-offs are between different resources and what considerations are taken into account in the resource strategy.

About Barbara:
Barbara has 15+ years of experience working for regulatory agencies around Arizona in Air Quality issues. A few years ago she started working at Salt River Project (SRP), working to ensure that the company and its power plants were in compliance with all air quality regulations, and that the company's goals focused on reducing emissions. To get a better insight on how a large utility plans for future generation and more customers, she slightly changed careers and went to work for SRP's Resource Planning group where she participates in siting or acquiring new generation (all types).
In her spare time Barbara likes to hang out with her family, listen to her husband ramble about all Linux things (most of which she doesn't understand), reading, and traveling.

The Meeting on 3/8 is Canceled

For the first time ever, we will need to cancel the PLUG meeting due to every single person that makes the meeting happen being out of town for the Southern California Linux Expo (SCaLE).
We encourage everyone to join us there if you can. There is still room to carpool with people and possibly share rooms to lower the cost of the trip.

If you would will like to get together with some PLUGgers, we encourage you to go and BJs, where we normally go to eat after the meetings, to hang out and talk.

Sorry for any inconvenience... We'll have more great presentations coming your way starting with the security meeting next week.
