Next Meeting

May 6 6pm

Note: due to Vassar campus response to covid-19, there will be no April meeting. We’ll tenatively hold this meeting in May. Check back for future updates.

When creating modern software, we often are lured into the latest and greatest new trends in software development. However, very often our old and reliable tools can provide us just as successful a path to success. And one of the most old and reliable tools is the humble SQL database.

This talk will look at the rebuilding of the scheduler / queue system for the IBM Quantum Experience, moving all the data from noSQL systems to PostgreSQL to get much better reliability, performance, and enable new features. It will look at a whole series of performance cliffs we hit as we grew the system, and how we got past them.

You’ll walk away learning things that PostgreSQL can do that you probably didn’t realize, and how you can take advantage of those to build high performance applications.

Speaker

Sean Dague is the founder of HV Open, and has a 20 year history working in open source communities. He’s currently leading the cloud services effort in the IBM Quantum Computing team. When not doing tech, he’s volunteering working on climate policy with Citizens’ Climate Lobby

Mad Science Fair's 8th year promises Robotic Fun

Makers of all sorts will be showing off their projects in this year’s Mad Science Fair coming up on Wednesday July 11th - 6pm at Lourdes High School.

The Mad Science Fair was thought up almost 10 years ago at the Palace Diner in Poughkeepsie by Joe Apuzzo, long time member of the HV Open Technology Meetup. Members of HV Open were discussing all kinds of projects they were working on over dinner. These ranged from simple blinking of LED lights, building radio equipment, to custom designing and manufacturing circuit boards overseas. “You know what would be great, if we had an old time Science Fair, but showing off all these projects to each other,” said Joe Apuzzo. “It would be like the Mad Science version of a Science Fair, a Mad Science Fair.”

And ever since then HV Open has dedicated it’s July meetup to the Mad Science Fair. Sophi Kravitz, notable local maker who works for Hack-a-day, once brought an interactive art project that pulsed light and sound based on your heartbeat. By using a pulse ox sensor, those typically used during a doctor visit, the art reacted to your own body, and made for a different experience every time a different wearer put it on.

Among the many projects this year will include robots, green screens, a learn to solder station, geothermal heating, and much more. Matthias Johnson, IT Director for Lourdes High School, is also the mentor for the Lourdes robotics team. Every year they compete in a statewide challenge to build and program robots to navigate a complex obstacle course. He’ll have some of the robots and parts of the course on display.

“It’s always a wonderful night. You find yourself learning so much, and talking with folks about incredible projects they’ve made.” said Sean Dague, founder of HV Open. “I always walk away inspired to create something new.”

The Mad Science Fair runs from 6 - 8pm on Wednesday July 11th in the Cafeteria at Our Lady of Lourdes High School in Poughkeepsie NY. For more information check out the HV Open website - http://hvopen.org.

The New HV Open Website

As part of the rebranding to HV Open it was time to simplify the platform for the website at the same time. I had a few requirements going into this.

  • There had to be a way to sync to meetup. I hate double data entry.
  • It should be mobile friendly / responsive.
  • The server costs to maintain should be low. That’s both hardware resources, but also the time it takes to do regular security maintenance of the software stack.
  • All the old meeting urls had to be maintained (even if through redirects). People put these in their resumes showing that they have public speaking experience.

MHVLUG becomes HV Open

HV Open Logo

15 years ago MHVLUG was formed around the nascent Linux operating system. Linux was just transitioning from the hobbyist and ISP realms into every day work in non technology businesses. What Linux needed was human networks where people could get together and help each other with what they were learning. MHVLUG was created to be that kind of place. We started a monthly lecture series to share our expertise. We held regular weekend install fests to help people install and configure Linux on their computers.
