      If you have an external clock that's transmitted exclusively over an analogue channel, then everyone would hear the beats at the same time (barring speed-of-light transmission times, which is really only a factor if the transmission uses geosynchronous satellites). But if there is any digital transmission then you're back to the same problem. Not everyone […]

      RT @lauraritchie @bobjonkman @strangeattractor what if they instead of playing reactively everyone played to a world clock? - people could always record their contributions and video magic can be done with screens in a room and then the one room is streamed.

      The solution would be to have an analogue connection from end-to-end. But today, even analogue phones are connected to digital switching networks, so you can't even use ordinary landline phones and expect to get no delay. You can get "leased lines" from the phone companies that are analogue end-to-end, but leasing a tuned circuit that […]

      Performing music together over an Internet connection is next to impossible if there is *any* lag at all. Typically, the lag is caused by short 10-50 millisecond delays for every router hop, at minimum one hop from you to your ISP, another from ISP to Internet Exchange Point (IXP), IXP to my ISP, and a […]

      RT @lauraritchie More on the livestreaming dilemma...I need to have the option of multiple participants AT THE SAME TIME - like playing in a band.

Ubuntu Activities during September 2013

It’s shaping up to be a busy few weeks for Ubuntoids in the Kitchener-Waterloo region:

Ubuntu Global Jam

Ubuntu Global Jam Kitchener Pictures!

When: Saturday, 14 September 2013 from 10:00am to 5:00pm iCal 1
Where: Computer Recycling
Location: 66 Queen St. S., Kitchener, Ontario, Canada Map 1
Entrance: Use the door on Charles Street
LoCo Event: Ubuntu Global Jam Kitchener | Ubuntu LoCo Team Portal
Info: UbuntuGlobalJam – Ubuntu Wiki
Blog: Charles’ Tech Talk: Ubuntu Global Jam, Saturday, September 14, 2013

Charles McColm (@chaslinux) has arranged to use the workshop at Computer Recycling on Saturday from 10:00am to 5:00pm, where he’s got lots of computers of varying specs that we can use to test the installation of Ubuntu 13.10 Saucy Salamander. We’ll document any problems with the installation procedure, any hardware incompatibilities we find, and maybe build a system or two in the process.

And for those people who don’t want to get grubby with actual hardware, there’s bugs to be triaged, documentation to be written, and code to be coded.

We’ll set up a couple of computers so we can be online with other Jams (it’s a Global Jam, after all), and Computer Recycling has a pretty good sound system so we can listen to the Hacker Freedom Song for inspiration all day long (OK, maybe not that).

Hellooo!

Just wanted to let you know the Guelph Ubuntu will be held this month on Friday, September 27, 2013 at the Pennywhistle Pub from 7 until 8 or whenever you feel like going.

Also, if you’re in the southern Ontario area, I suggest you check out the Ubuntu Guelph oriented mailing list. It’s available from Launchpad at ubuntu-ca-guelph@lists.launchpad.net . We also have an IRC channel set up at #ubuntu-ca-guelph .

Continuing from last month, I plan on sending out an email with a link to the survey I designed for last meeting so that everyone can fill it out once I figure out how to make a Google Apps for free form publicly accessible.

Thanks,
Verdi

OpenDataDay Hackathon at Kwartzlab

Posted by Bob Jonkman on 27th February 2013

Open Data Waterloo Region

 

On International OpenDataDay four teams of hackers from OpenDataWR gathered at Kwartzlab to work on Food Premise Inspection Data, modelling new transit routes and route changes with GTFS data, improving the server for the Catchr transit app, a proof-of-concept pushbutton app for Android, and creating a Get Map button for OpenStreetMap in the Thunderbird Lightning add-in.


Hackers at Kwartzlab OpenDataDay Hackathon at Kwartzlab. Clockwise: Koo (back to camera), Ralph, Michael, Mike, Brett, Jonathan. Missing: Darcy, William, Katherine, Bob.

 

William and I worked on the Get Map button. Although we had hoped to create some working code, we got only as far as making a mock-up of Lightning’s Edit Event screen:

Screenshot of Thunderbird Lightning Edit Event screen
Lightning “Edit Event” screen, showing the new “Get Map” button

 

The first hurdle we ran into is that Lightning source code is kept in a Mercurial repository. Although William was familiar with Perforce (another code revision system), I haven’t used Mercurial until now. And the repository contained all of Thunderbird, Firefox, SeaMonkey, and the Mozilla addins. We certainly didn’t want to clone the entire Mozilla code base! So William found the Lightning tarball, which I unpacked in a new folder. This let us poke around the source files to find where our new code should go.

Then we found that Lightning isn’t straight Javascript, it’s mostly XUL. XUL is close enough to XHTML, CSS and DTD files that we could figure out what needed to be done. But we had a limited amount of time, and I didn’t want to spend it waiting for source code to build. So I created a new profile in Thunderbird, installed a fresh copy of the Lightning add-in, and we hacked at the installed files directly. This gave us instant feedback on the changes we made, just by restarting Thunderbird and running Lightning. Some of the changes were in plain text files, but others needed to be made to files in JAR format. One of those was the localized language file. We weren’t sure which language file we were using, en-GB or en-US. Of course, we picked the wrong one to start with, and spend maybe two hours trying to debug a misleading error message about a missing entity definition while we were working on the wrong file.

But it all turned out OK in the end. Now we need to take the work we did on the installed files and replicate it on the source files from the Mercurial repository, properly build Lightning from source, and offer our changes to the Mozilla Calendar project. And, once we’ve got it working, we’ll make the changes available on this site too.

–Bob and William.

More GNU/Linux Resources

People have asked me about GNU/Linux resources in K-W, so here are some of them, gathered in one convenient place. This is by no means an exhaustive list (yet). If you know of others, please let me know in the comments.

KW Linux Users Group — http://kwlug.org
The KWLUG mailing list for general discussion is where all the action is, along with a “Help” list for specific questions. Microblogging as @kwlug and !kwlug on Identi.ca and also @kwlug on Twitter.
Ubuntu Canada KW chapter — https://wiki.ubuntu.com/CanadianTeam/KitchenerWaterloo
There’s a low traffic Ubuntu-CA-KW mailing list. Microblogging on Twitter as @ubuntuwaterloo and on Identi.ca as @ubuntuwaterloo too, with a group at !ubuntucakw. Some members can also be found on the IRC channel #ubuntu-ca-kw on Freenode.net.

Ubuntu-CA-KW has regular Ubuntu Hours in Kitchener (first Friday of the month) and Waterloo (third Wednesday of the month) announced on Identi.ca, Twitter, and sometimes the mailing list.

Ubuntu Canada — https://wiki.ubuntu.com/CanadianTeam
Again, the Ubuntu Canada mailing list is where the action is, but there is also a web forum and the Ubuntu-ca.org website. Check out the Ubuntu Canada events listing. There’s an !ubuntuca group on Identi.ca, and many people can be found on the IRC channel #ubuntu-ca on Freenode.net.
Computer Recycling — http://theworkingcentre.org/at/comp_recycling/comp_recycling.html
Computer Recycling at The Working Centre sells refurbished computers pre-installed with GNU/Linux, and offers a repair shop with staff and volunteers who are enthusiastic and knowledgeable about GNU/Linux. Every Saturday is Ubuntu Day: 10:00am to 4:00pm, Hours are Tuesday to Friday, 10:00am to 5:00pm, at 66 Queen St. S. in Kitchener (use the entrance on Charles St).
Kwartzlab — http://kwartzlab.ca
You’ll also want to keep an eye on Kwartzlab, the local makerspace where many of the Ubuntu events are held. There’s a discussion mailing list for members and non-members alike. Visit the workshop on Tuesday Open Night, 7:00pm to 10:00pm at 283 Duke St. W., Kitchener.
Watcamp Calendar — http://watcamp.com

Also check the Watcamp calendar for other GNU/Linux and many other tech events happening in the Waterloo area.

That should keep you going…
