Serial logging: best practice, pitfalls, advice?
by Stewart C. Russell 17 Sep '14

17 Sep '14

Hi, Since there are some really experienced system people here, I'd like to ask some advice on designing logging parameters for a serial device. I'd like to design the output log so it's most obvious to users what's coming out the thing, and so it's easy to stuff readings into a database for later analysis. I have complete freedom to redesign the log coming out of this embedded device. Here's what I get from the device: 1. Approximately twice a minute, I get a cumulative energy reading and the average power for the last 30s or so 2. About once every five minutes, I get a packet which contains an approximate (±1°C or so) ambient temperature I can also report: * a fairly accurate (at least over the short term) elapsed time stamp in milliseconds - but not real time, as there is no RTC. The time stamp rolls over slightly more than once a month. * the received signal strength in dBm This device is decoding the RF packets from the BlueLine Power Cost Meter that the OPA and local utilities give out to hydro consumers in Ontario. It's also the same as the Black & Decker Power Meter. The device would allow you to track real-time energy consumption without fiddling around with Toronto Hydro's time-of-use website (or, gulp, having to mess with Green Button energy files - eek!). As it counts the hydro meter's watt-hour pulses, it's pretty accurate. So - I'm currently logging something like this [105874810] Energy: 63856 Wh, Power: 613 W, Temp: 14 C (Rssi -81 dBm) where the first number's the timestamp. * Would this format cause hiccups in typical logging applications? * Is 9600 baud still the gold standard serial speed? I can use pretty much any speed, and there's never much data to transmit. Any suggestions/questions greatly appreciated. If anyone has one of these OPA Power Cost Meters, and wants to have a play with it, you'll need: * a 3.3 V Arduino (or a standard 5V one and some level converters that can do SPI) * an RFM69 433.92 MHz transceiver board (caution: it uses 2 mm pin spacing, so won't fit a standard breadboard) * this code: https://github.com/CapnBry/Powermon433 The output is rough, but I've successfully tracked several days' power use so far with far higher resolution than is available from smart meter website. cheers, Stewart

Afternoon Tea with LibrePlanet-Ontario, TorontoCrypto and Ubuntu Canada
by Bob Jonkman 11 Sep '14

11 Sep '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Everybodeee! Thanx for welcoming me to the ranks of GTALUG membership last night! As I mentioned at the meeting, there's going to be a get-together of Free/Libre-minded software folks this Saturday afternoon. The whole thing was started when Sergio Durigan, the organizer of LibrePlanet-Brazil moved to Toronto and re-activated the LibrePlanet-Ontario group, and I offered to introduce him other Free Software groups. LibrePlanet-Ontario - http://libreplanet.org/wiki/Group:LibrePlanet_Ontario LibrePlanet exist to promote the use of Free Software in the communities of Ontario and to support individuals who wish to use or create Free Software. The goals are similar to those of the Free Software Foundation. Recently one of LibrePlanet-Brazil's organizers, Sergio Durigan Jr. moved to Toronto and is now helping organize LibrePlanet-Ontario. Let's show him a warm Canadian welcome! TorontoCrypto - https://torontocrypto.org/ CryptoParty is a decentralized, global initiative to introduce the most basic cryptography software and the fundamental concepts of their operation to the general public. TorontoCrypto held a workshop on computer privacy and security software in July; let's practice those new skills by holding a GnuPG/PGP keysigning and extending the Web of Trust to the other organizations. Ubuntu Canada, Toronto chapter - https://wiki.ubuntu.com/CanadianTeam/Toronto/ This weekend is the Ubuntu Global Jam, where the Ubuntu community unites to work together to improve Ubuntu. We've got some Ubuntu DVDs to give away; bring your laptop and try it out. Everyone is welcome to Afternoon Tea, whether or not you're affiliated with LibrePlanet, TorontoCrypto or Ubuntu Canada. *What* : Afternoon Tea *When* : Saturday, 13 September 2014 from 3:00pm to 6:00pm *Where* : Yueh Tung, 126 Elizabeth Street, Toronto, Ontario *Website* : http://yuehtungrestaurant.com/ *Map* : http://osm.org/go/ZX6BtDPG?m= *Register* : http://loco.ubuntu.com/events/ubuntu-ca/2883/detail/ And a week later we're celebrating Software Freedom Day in Kitchener. It's an all-day event with a stream of presentations including one on Open Data and one on Open Access publishing, a hands-on workshop on Scratch programming and one on Privacy and Security with Tor, a film festival, and an all-day installfest. Everything is free, both in the sense of Libre and Gratis. We're even giving away computers at the installfest (monitors are $20). *What* : Software Freedom Day *When* : Saturday, 20 September 2014 from 10:00am to 4:00pm *Where* : Queen Street Commons Cafe and The Working Centre *Location* : 43 and 58 Queen Street South, Kitchener, Ontario, Canada *Map* : http://osm.org/go/ZXnwTzH0?m= *Schedule* : http://wiki.softwarefreedomday.org/2014/Canada/Kitchener/TWC?action=AttachF… *Website* : http://kwlug.org/sfd Hope to see you at either or both events! - --Bob. - -- Bob Jonkman <bjonkman(a)sobac.com> Phone: +1-519-669-0388 SOBAC Microcomputer Services http://sobac.com/sobac/ http://bob.jonkman.ca/blogs/ http://sn.jonkman.ca/bobjonkman/ Software --- Office & Business Automation --- Consulting GnuPG Fngrprnt:04F7 742B 8F54 C40A E115 26C2 B912 89B0 D2CC E5EA -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (GNU/Linux) Comment: Ensure confidentiality, authenticity, non-repudiability iEYEARECAAYFAlQRNQ0ACgkQuRKJsNLM5erPYgCgi8uWhvUiNONkFs5Q2wrLsW7I VNIAoMGXExwC6e0nGFdpS4QkktET7jP1 =xqpg -----END PGP SIGNATURE-----

darktable - a rather good photo workflow for Linux
by Stewart C. Russell 10 Sep '14

10 Sep '14

Hi, Don't know if there are too many photography nerds here, but I've discovered a very nice package for managing raw photo publishing: darktable - http://www.darktable.org/ It's not really a pixel editor like Gimp. You can add a whole variety of transforms and filters to a group of pictures, and then export them all, leaving the original files untouched. It works in 32 bit/pixel floating point, so you don't get quantization issues. darktable's UI is a little odd, and it will take you a few hours to learn how everything works. After you learn, it works just fine. cheers, Stewart

Re: [GTALUG] New GTALUG Mailing List
by D. Hugh Redelmeier 10 Sep '14

I think that this will be MY LAST POST TO tlug(a)ss.org. And it is my first post to talk(a)gtalug.org. | From: Ken Heard <kenslists(a)teksavvy.com> | I will consequently | unsubscribe from the old list and subscribe to the new. I don't know if the "unsubscribe" is necessary or even a good idea. How are the old and new lists connected? I subscribed on Monday evening to the new ones and have not unsubscribed from the old one. I have not received any double-posts. In fact, all messages I've seen seem to be from the old list. I'm sending this message to both old and new lists. Let's see what happens. If there is no automatic cross-posting, one should stay subscribed to both old and new lists.

An essay griping about PGP
by Christopher Browne 27 Aug '14

27 Aug '14

I rather liked the line about "Cryptography that post-dates the Fresh Prince." :-) http://blog.cryptographyengineering.com/2014/08/whats-matter-with-pgp.html It's also definitely onto something with the line: "The TL;DR is that 'trust' means different things to you than it does to me." -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"
