Ice cream social and kite flying!

12:30 pm

Location: That park by Steve Fox's house, officially known as Pine Ridge Estates Park, on Redwood Lane SW.

This park has a nice playground for the littles, picnic tables, and room to fly kites, as well as usually being unpopulated. The lack of trees and being on top of a hill mean it's pretty bug free even when there's not enough breeze to fly the kites.

Please bring your family and friends who might want to hang out. Bring your own kites. If you don't want to sit at the picnic tables or on the playground equipment, bring your own folding chair. And bring your own beverage. Tina will bring the ice cream.


Social: Tuesday July 18th 2017

CANCELLED DUE TO RAIN

6 pm

Disc golf! Just up the road outside the RCTC field house. Meet at the parking lot edge / field house doors, 6:30 pm.



Technical Meeting: July 13th, 2017

Dennis DeLorme, giving a talk about Arduino programming. He has provided the following summary:

---

I use Arduino based boards for various monitor and control projects. The Arduino has a variety of I/O functions (digital, analog, serial, spi, etc) but reasonable user interfaces are limited. Permanent storage options are also limited.

The Android has a nice graphical user interface and built in permanent storage. The external I/O is limited to USB, audio or wireless. There are on board sensors but they are limited, particularly on low end devices.

My thought was to combine the rich Arduino I/O with the Android GUI and storage. The use of the Android I/O is complex which can limit its use. I have found working examples for USB to serial and Blue Tooth interfaces. (I felt like I was back on the farm with a pitchfork sorting through the Internet sites to find a few pieces of usable code!) I will present a simple demonstration of connecting an Arduino and Android to control an LED and sense temperature. (Note: even low end Androids have a "temperature sensor" but it measures the CPU temperature.)

If you have an Android device with Blue Tooth, and are adventurous download Blue Serial by Plasty Grove from Google Play and bring it along. You can then do a demo of controlling my Arduino via Blue Tooth. This is the code I used as a base for my Blue Tooth interface. He (she?) has abandoned the project but gives the link to the source code in the "READ MORE" section. The source is for Eclipse but can be imported to Android Studio relatively painlessly.

RochesterFest lunch: Thursday June 22nd

June downtown lunch at RochesterFest (Soldier's Field track oval), Thursday June 23rd, 11:30 am, weather permitting (rain date TBD). For those of you downtown who aren't up to walking that far (or your schedule doesn't permit the extra time), they are doing free trolley rides again 11-2 from in front of the Marriott Hotel; and new this year they're adding a trolley run from St. Mary's (Monday and Thursday only, we got lucky). Hopefully they will publish some coupons for food vendors again this year, if so I'll add a link later. Here's a map of the vendors and a listing of items to be for sale.


Social: Saturday June 10th 10am - 2pm

Socializing at the Voldal's. We will have options for outdoor weather and indoor weather. Bring your favorite outdoor or indoor games. We do have an old beagle, but she will either be upstairs or on a leash (so that she doesn't eat your food). Here's a signup table so everyone can be aware of who's bringing what.

People Providing Food Other
Dee & Erik Voldal Light lunch of "make your own sandwich", and fruit, and a basic beverage selection of milk, juice, and water. Backyard games (bean bag, kubb, bocce, a single disc golf hole, kid pop-up tunnels, etc). Indoor activities (board games, table tennis, foosball, darts, kid toys).
Tina family of 4 Vegetable pasta salad Something if outdoors. If indoors weather, non-reading required board games.
Ed & Sylvia Fishel Potato salad
Will family of 3 Not sure. possibly potato chip assortment.
DeLorme empty nesters of 2 Fresh Strawberries clean in a bowl Testicle toss (Connie made me say this) aka ladder golf

Technical Meeting: June 8th, 2017

Vi Grey, on attacks used against 2-factor authentication, and why people should still be using 2-factor authentication wherever they can.

--

With account data breaches occurring at companies, a password alone isn't enough to protect our accounts. Two-Factor Authentication has been introduced in more services, but it isn't perfect. In this presentation, I explain the importance of Two-Factor Authentication and attacks against different forms of Two-Factor Authentication. I will also be debuting my proof-of-concept Man-in-the-Middle attack on FIDO Universal Second Factor (U2F) USB hardware authentication.

Topic: An Introduction to Docker

Containers seem to be the current buzzword, and Docker is at the head of the list. Join us for an introduction to the world of Docker containers, and a practical demonstration as well. We’ll look at how to use Docker from the command line, and how it can be managed via a web interface. We’ll also discuss some security aspects which various vendors are trying to address. The presentation will be interactive, with questions welcome.

Speaker: Robert Nix

Bob is a Linux Systems Engineer at Mayo Clinic, and has worked with operating systems for 18 years for Mayo, and another 20 before that at various large companies.

Here are his slides, most of the presentation was a live demo.

Technical Meeting: March 9th, 2017

The March meeting topic - you! Yep, this meeting will be all about you, in a low-preparation way.

--

The topic for mini-presentations: If you knew then what you know now, what if anything would you do differently for:

a) hardware choices

b) programming languages

c) software investments

d) job choice

e) where to invest your computer/tech-related volunteer time

f) anything else computer/tech related that you feel up to passing judgment on (if you have topics to suggest people brainstorm on, please send those to the list)

--

So please attend, and be prepared to offer some opinions. No Powerpoint required.

As extra encouragement to attend, and for those of you who are PCIG members to be present for voting, don't forget that our annual March meeting is also a celebration of Pi day! Courtesy of family support, we have semi-homemade peach pie, and thawed key lime pie, to enjoy.


And PCIG officer nominations and elections.

Technical Meeting Social : February 9th, 2017

We did not get any volunteers for speakers, so we'll go play instead.

We're going to hang out at the Machine Shed. Costs are:

$10 ages 13+

$5 ages 8-12

7 and under are free with paid adult

The Machine Shed website.

They're open from 4-8 pm, and the cost is flat per session, so if you feel like arriving early for longer gaming that's certainly fine. They also sell snacks, drinks, and pizza, so you can come straight after work.

They are located at 11 2nd St NE, Rochester, MN 55906 in the east portion of the Wausau Homes building (look for the two large garage doors and the entry door).


Note that the signage is almost non-existent, they have a plain text-only sign on the appropriate door, but no big sign on the building. The parking lot there IS for customers, or you can park on the street. I won't be attending, you'll have to gather around someone else.


Social: Saturday February 4th

We will go for a sleigh ride at WinterFest for our February social. That's Saturday, February 4th, at 10 am.

Park along the road on Salem Road, the sleigh rides are north of the road behind the History Center.


Social: Tuesday January 24th, 2017, 6 pm

We're going to hang out at the Machine Shed, thanks go to Mark D for the idea. Here is some recent advertising from the local newspapers.

Technical Meeting: January 12th, 2017

Paul Zellweger and Jason Thompson of ArborWay Labs, on their automatic database application Studio. Handout / presentation outline


ArborWay Labs presents a demonstration of its automatic relational technology or ART Studio

ArborWay Labs will present a live demonstration of its automated relational technology system called the ART Studio. It is a proof of concept that generates database applications automatically using context-sensitive interfaces that guide designers through our step-by-step process. In the first half of our presentation, we will explain how and why our technology breaks new ground with the RDBMS on the white board. Next, we will build a small database application from a 5-table database system that will be posted on our server. The audience will be encouraged to browse and explore the “100 Best TV Episodes database” on their own personal computing devices. This part of the demonstration will be limited to smart phones, tablets, and laptops. Stay tuned for the launch of our smart watch database applications in the Summer’17.

ArborWay Labs is a Rochester, MN based start-up that aims to change the way today’s professionals build and distribute database applications. With ArborWay’s ART Studio, database applications are generated by a design activity that automates the production of SQL, object-relational mapping, and all code that was previously crafted by hand.


It is rumored Dennis may be having a birthday (and providing cupcakes), and ArborWay is providing two pizzas.


Also, K-LUG officer elections, and PCIG officer nominations.


6 pm, in or near RCTC Heintz Center's HA107.
