For some reason, I didn't get my first post. So, here is again. Note the room change. -- William ----- Forwarded message from Dalibor Dvorski <Ddvorski(a)conestogac.on.ca> ----- Date: Thu, 31 Mar 2016 23:53:58 +0000 From: Dalibor Dvorski <Ddvorski(a)conestogac.on.ca> Subject: (important) notes for this weekend's Software Carpentry event To: Dalibor Dvorski <Ddvorski(a)conestogac.on.ca> Content-Type: multipart/alternative; boundary="_000_14594684397127837conestogaconca_" Dear attendees of the Software Carpentry workshop this weekend, we please ask that you review the following information prior to arriving for the workshop. ** Room Change ** Please note that we will be in room 1E05 (not 2A301 as originally advertised), as it is better equipped to handle our event. Please refer to "The Venue" section below for directions to the college and this room. Software Setup (and assistance) Please prepare the required software on you laptop by following the operating system specific instructions on our event page: http://ppomorsk.github.io/2016-04-02-conestoga/. If you encounter any difficulties in the setup, let me know by replying to this message. Referring to the Saturday schedule on our event page, you will see that we have set aside one hour prior to the start of the first workshop to help attendees through the software setup. If you require this assistance, please shortly before 9:00 on Saturday and we will be most happy to help you install the software required for the weekend. Otherwise, if you can install the software yourself today or tomorrow, then you may arrive shortly before 10:00 for the first session on the Unix shell. The Venue Our workshop is being organized at the 'E' wing of Conestoga's main campus in Kitchener at 299 Doon Valley Drive. For maps, please refer to http://conestogac.on.ca/campuses/doon/ and http://conestogac.on.ca/campuses/doon/siteplan.jsp. The workshop will be organized in room 1E05, which is on the underground level of the 'E' wing. The following two maps will assist you in getting to the room: http://conestogac.on.ca/campuses/doon/e1.jsp and http://conestogac.on.ca/campuses/doon/e2.jsp (level 2 is ground level, level 1 is underground level). Parking We will provide free parking for the event. Referring to the above maps, we ask that you please park on one of the following lots: 13, 13B, 12, 11, or 14. Grand River Transit For those using Grand River Transit for transportation to and from the event, Conestoga's campus is accessible using route 10 from Fairview Park. Please note that routes 16, 61, 110, 111, 116, and 203 are not in service at the college during weekends. For those visiting us from University of Waterloo or Wilfrid Laurier University, you may use iXpress route 200 from Waterloo to Fairview Park and then transfer to route 10. For those unable to attend the early sessions due to the reduced weekend service by GRT, you are still most welcome to attend the later sessions! Lunch Lunch has been scheduled at 1:00 p.m. on both days (please refer to the event Web page for the full schedule). Such that you have an opportunity to interact and network with fellow attendees, we recommend that you bring your own lunch. If you prefer to buy lunch, the on-campus Tim Hortons will be open on Saturday, but not on Sunday. You may also visit McDonald's, Tim Hortons, Mango King, or Pino's Pizza across Homer Watson Boulevard and a five minute walk from the venue of our workshops: https://www.google.com/maps/place/299+Doon+Valley+Dr,+Kitchener,+ON+N2P+2N6…<https://www.google.com/maps/place/299+Doon+Valley+Dr,+Kitchener,+ON+N2P+2N6…> Coffee and Tim Bits We will provide attendees with free Tim Hortons coffee and Tim Bits during both days of the event, starting at the first morning break. Draws for Free Raspberry Pi computers and Gift Cards Since this is a computing event after all, the draws for the two Raspberry Pi computers, two $20 Conestoga Bookstore giftcards, and two $20 Chartwells lunch cards will be done electronically. Please refer to the event schedule on when these draws will be taking place, and keep an eye on your email inbox at these times to see if you have been selected. If selected, you will then pick up your gift in person at the event. All registered to attend the event will be included in the draw, but in order to receive your gift, you must be physically present at the venue if and when your name is chosen. Thank you, everyone. If you have any questions, please let me know. We look forward to seeing you this weekend! Dalibor ----- End forwarded message -----

[GTALUG-Announce] GTALUG Meeting on 12th April at 7:30pm
by Myles Braithwaite 31 Mar '16

31 Mar '16

<http://gtalug.org/meeting/2016-04/> # Open Source Graphics Suite Panel Join Stewart, Trent, and Myles in discussing their practical experiences using a variety of open source graphics packages and suites. Bring your questions for our panelists! ## Panelists Stewart Russell is a Linux user who should probably be kept away from admin, dev and other sharp objects. He draws mostly geometric patterns and enjoys unusual output devices such as pen plotters. He mostly works in Inkscape, but also finds graphical uses for Gimp, Darktable, QCAD, OpenSCAD, Processing, Perl, PostScript, Python, netpbm and — when all else fails — ink and gouache. Some of his work is here: <https://www.flickr.com/photos/scruss/sets/72157666420609652/> --- Trent Drake is a freelance artist, with two decades experience in drawing anthropomorphic characters. A former qualitative data analyst, he continues to branch out in game design, animation, cartooning. He also directs and produces independent video productions for community organizations and YouTube. He works in Windows, using Inkscape, GIMP, and Blender. Links to content: * The Safety Prance: Lyricist, prop-builder, director: <https://www.youtube.com/watch?v=5dIu8gHkzEs> * Pixel art gallery: <https://www.weasyl.com/submissions/hiker> --- Myles Braithwaite is a web developer who sometimes has to designs user interfaces. He accomplishes this by using Open Source design tools like Inkscape for icons and wireframes, Dia for structure diagrams, and GNUpaint for rough sketching. He enjoys manipulating SVG files and manipulate them with Python and CSS (he was doing it before it was in vogue). On the rare occasion he has to interact with dead trees he uses Scribus to design page layouts. ## Location George Vari Engineering and Computing Centre 245 Church Street, Room 203 Ryerson University <http://goo.gl/maps/16oJ2> <http://www.openstreetmap.org/way/23447525> ## Schedule * 6:00 pm - Please discuss on the general mailing list (i.e. <talk(a)gtalug.org>) where you want to go for dinner. * 7:30 pm - Meeting and presentation. * 9:00 pm - After each meeting a group of GTALUGers move to the The Imperial Pub (54 Dundas St East) for refreshments and more socializing. # Code of Conduct We want a productive happy community that can welcome new ideas, improve every process every year, and foster collaboration between individuals with differing needs, interests and skills. We gain strength from diversity, and actively seek participation from those who enhance it. This code of conduct exists to ensure that diverse groups collaborate to mutual advantage and enjoyment. We will challenge prejudice that could jeopardize the participation of any person in the community. The Code of Conduct governs how we behave in public or in private whenever the Linux community will be judged by our actions. We expect it to be honored by everyone who represents the community officially or informally, claims affiliation, or participates directly. It applies to activities online or offline. We invite anybody to participate. Our community is open. Please read more about the GTALUG Code of Conduct here: <http://gtalug.org/about/code-of-conduct/>. If you have any questions, comments, or concerns about the GTALUG Code of Conduct please contact the GTALUG Board @ <board(a)gtalug.org>. --- GTALUG Announce mailing list announce(a)gtalug.org https://gtalug.org/mailman/listinfo/announce

Multi threaded application fails with error Out of Job Buffers
by Randy Jonasz 30 Mar '16

30 Mar '16

Hey everyone, I'm trying to switch my mysql cluster to use the multi threaded data node. But when I start a node using ndbmtd on ubuntu 14.04 using kernal 3.13.0-79- generic I get an error that the job buffers are exhausted. Is there anything I can do to fix this or should I wait for 16.04 and a newer kernel? Thanks! Randy

Thought some might enjoy this, the older folks. This is BITS AND BYTES from TVO back in about 1983. This is likely for me the first spark that light my fire into the computer field. https://www.youtube.com/channel/UCCEyRso1NoDBilXd0YaPAdg https://www.youtube.com/watch?v=XC_T5mvuguw&list=PL77441A2ED0D0B6A8

Wget under-reports data transfer rate ("bandwidth") by 5%
by Peter Renzland 23 Mar '16

23 Mar '16

Wget can be used to measure download data rate. For example, wget --output-document=/dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip Then observe the progress meter and kill the process. IMHO, wget thinks a MB is 2^20 (== 1MiB), instead of 10^6. This results in a 5% error. (Softlayer seems to have made the same error.) Am I wrong? Have others noticed that? According to wget's definition of "bug", this error does not seem to be a "bug". Or? (It doesn't crash -- just gives a wrong answer, based on a wrong assumption.) -- Peter Renzland(a)gmail.com

Might be of interest to the list: I just finished reading "Turing's Cathedral" by George Dyson about the early days of digital computers (and a very cool account of the first cellular automaton running in 5K memory!) and - looking for more information about Boolean algebra and logic - came across this free online course that builds a virtual machine from first principles ... https://www.coursera.org/learn/build-a-computer http://nand2tetris.org/ Next session starts March 28. -- (o< .: Per curiositas ad astra .: http://www.circuidipity.com (/)_

Linux and Stereo Speaker Cables
by Randy Jonasz 21 Mar '16

21 Mar '16

I know this is a stretch but I do listen to my stereo with my Manjaro laptop connected to a DAC connected to my amplifier. Could any electrical engineers offer advice about the difference stereo speaker cables make to sound? Thanks! Randy

email etiquette.
by Alvin Starr 21 Mar '16

21 Mar '16

Hugh Redelmeier posted a message to the list about my posting replies at the top of messages. We have had a bit of a discussion offline about this but Hugh suggested we take it back to the list and see what the feelings of others are. My position is that posting at the top is most efficient and the easiest for the reader. As for clean up I agree that long email chains can become a pain specially when answers are posted at the bottom. I tend to clean up when the messages get to a couple of screens and replace the removed section with [snip]. Hugh follows the ideas put forward in: <http://www.idallen.com/topposting.html> What do others think? -- Alvin Starr || voice: (905)513-7688 Netvel Inc. || Cell: (416)806-0133 alvin(a)netvel.net ||
