Re: [Wlug] Postgres cluster

by Jason Couture

We did a few tests, for our purposes it turns out that postgres was quite a bit faster than MySQL, but its setup is quite a bit more complicated.

Sounds like a good project. I wish I could offer some advice, but I am not familiar with postgres. I hope someone else on this list has some ideas. I've been meaning to do more things with mysql as it seems to be the gateway dbms and since I used it for a project a few years back.

Vintage Computer Festival East 2012

by Evan Koblentz

Hello, I'm writing to user groups and hackerspaces to inform your members of a very unique upcoming event -- the Vintage Computer Festival East 8.0, May 5-6, in Wall, New Jersey. If you're not familiar with the Vintage Computer Festival, then please take a moment to keep reading .... The event is run by a user group called MARCH (Mid-Atlantic Retro Computing Hobbyists) of which I'm president. Each day of the weekend-long show contains lectures/workshops (in the morning) and an exhibit hall (in the afternoon.) This year's keynote speakers include Dartmouth's Dr. Thomas Kurtz, who co-invented BASIC (on Saturday) and Apple's Daniel Kottke (Steve Jobs' college buddy, India travel companion, Apple 1 board builder in Jobs' parent's garage, and Apple II/III/Mac engineer), on Sunday. Both days, in the afternoon, is our hands-on exhibit hall. Imagine an antique car show -- the cars are nice to look at, but you can't touch anything, and you certainly can't drive. Well, that is no fun at all! Our exhibitors are required to have their systems up and running for live demos all weekend! People can see minicomputers, punch card machines, teletypes, homebrew-era computers, 8-bit micros, etc., all live and running. The venue for our event is the InfoAge Science Center, which is a grassroots, all-volunteer, non-profit facility. It contains a computer museum (run by my user group), along with museums for antique radio/TV, shipwrecks, military communications, amateur radio, etc. -- all operated by independent clubs. Best of all, our event is dirt-cheap to get in. Adult tickets are just $10 a day and $15 for the weekend. Kids are admitted for free. Proceeds benefit our museum, which is strictly educational in nature -- we're all volunteers. In fact, we all lament that our jobs and families interfere with our volunteer time. :) Details are frequently updated at http://www.vintage.org/2012/east/ and http://www.facebook.com/vcfeast8. We'd be very grateful if you could share this announcement with your group members. People attend the Vintage Computer Festival East from all around the U.S. and even from other countries and continents. For now, however, we're reaching out to our fellow user groups around the northeast and mid-Atlantic. Thank you, - Evan Koblentz (evan(a)snarc.net, cell: 646-546-9999)

Postgres cluster

by Jason Couture

Could someone walk me through building a 3 machine postgres cluster with automatic fail over? I've searched and searched and I'm just not getting it. I currently have postgres 9.1 installed with 1 database as 9.1/main. I'd like to cluster this to provide ha and faster query times. Writes to the DB can be forced to the master only, so read-only slaves are okay (there are far more reads than writes) Can anyone help me out?

Super Wifi arrives in Hanover County, NC

by Tom Poe

Just read that Hanover County, NC, is moving to the FCC's authorized use of unlicensed broadcast frequency ("white spaces"). So, maybe it's a good time to put a proposal together to get our state counties to do the same. Anyone know the technical specs that would lay out a viable solution our county commissioners can consider? If you're interested, please contact me, or maybe we could discuss this as a topic on the mail list (best). Thanks, Tom

Re: [Wlug] Where to find a software contractor?

by James Gray

I am subscribed to the boston python programming language meetup group and there are a lot of job ads on their email list. The jobs need to be relevant to the python programming language, but python sounds like as good a language as any for the type of project you describe. http://meetup.bostonpython.com/ A friend of my wife used elance.com.
