MTS DSL Speeds
by John Lange 18 Apr '05

18 Apr '05

I see MTS has 3 different DSL services: Light Speed DSL, DSL High Speed, Lightning Speed DSL. Surprisingly, the web site does not indicate what the speeds are (other than "fast", "faster", "fastest"). I'm curious what the theoretical upload speeds are for each level? If anyone is actually using these services, what is the "real" upload speeds you get? Thanks. John

Toshiba Achieves Breakthrough in Flatbed 3-D Display

Rather timely announcement, after my presentation last Tuesday... http://www.toshiba.co.jp/about/press/2005_04/pr1501.htm Not sure if they licenced the technology from one of the patent holders... If not, we might start to see some legal activity on that front. In any case, it will be interesting to see what sorts of products and applications emerge. -- Gilbert E.

Re: [RndTbl] The early days of Unix

According to Peter C.J. Graham: > 75 pre-dates both Gilbert and myself, I believe but there certainly > was a PDP 11/45 here in the late 70's. I'm not sure what whether the > original 11/45 was around in 75. Might just have been someone who was > interested but didn't have hardware yet. Gilbert, do you know if Doug > was active with Unix at that time? My earliest recollection, and earliest contact with the department of Computer Science, is from the spring of 1978, when I came for an open house. I saw the Norpak graphics system as well as some other demos, which I later learned made use of the PDP 11/45, behind the scenes, running UNIX Sixth Edition. By the time I started working (part-time) for the department, late in my first year of study, in 1980, the PDP 11/45 was still running UNIX 6ed. One of the first tasks that my brother and I undertook, when we were put in charge of administering that machine a year later (summer of 1981), was upgrading to UNIX 7ed, which had been released in 1979, and which had been purchased and was (sadly) sitting on the shelf for almost two years. I have no knowledge of specifics pre-1978, but I'm quite sure the PDP had been around for a few years already, so it's quite possible that UNIX 6th edition (released May 1975*) had been purchased for it, or in anticipation of using it at a later date. According to Bill Reid: > > John, > > > > Thanks for the URL. That list which includes U of M was a 1975 Unix mailing list > > not a list of Internet nodes. The U of M did not become an Internet node until > > 89-90. And one of my first tasks after going to work full-time for the department, in the fall of 1989, was to get our systems Internet-ready. > > Gilbert were you at the U of M in 75? I'm not _that_ old! ;) > > I think Computer Science ran Unix on a PDP in the early days. Yes, they did, but I'm not sure how far back the "early days" go in this case... * History of UNIX / Linux and other variants http://www.computerhope.com/history/unix.htm -- Gilbert E.

The early days of Unix
by John Lange 17 Apr '05

17 Apr '05

There is a nice article on Growklaw which describes the very early days of Unix. Denice Richie, Ken Thompson, etc. http://www.groklaw.net/article.php?story=20050414215646742 One thing caught by eye; about 1/2 way through there is a listing of the original 20 or so nodes of the internet and guess who is there? The U of Manitoba! (along with 3 other Canadian universities). A fascinating read for anyone interested in the birth of the modern Internet and Unix. John Lange

Backing up over the Internet
by Bill Reid 16 Apr '05

16 Apr '05

Rsync works great to back up directories over the Internet. For security I was interested in having the backup copy encrypted and rsync does not really work in this senario. I found two candidates for this: Box Backup http://www.fluffy.co.uk/boxbackup/ duplicity http://www.nongnu.org/duplicity/ I am giving Box Backup a try. Has anyone used either of the these systems? Are there other suggestions? Thanks, Bill

Printing PDFs in Linux
by John Lange 15 Apr '05

15 Apr '05

We have a report server which generates PDF files. These reports are 8-1/2" x 14 (legal). Under windows, Acrobat reader will scale these to print on 8-1/2" x 11". As far as I can tell there is no way to do something similar in Linux. Does anyone have a suggestion on how this could be done? John

You can get a stereo effect by alternating rapidly between the left and right images of a stereo pair. Some examples are at http://ofwonder.com/blink.html. Move your mouse higher or lower on the page to find a blink rate that works for you.

Is it a platform that will be forever relegated to nerd space or does it have a real commercial role to play? And how do you get in on the act? Find out "what's up" with open source right now at the only forum of its kind in Atlantic Canada. CEOS The Conference on Engaging in Open Source May 12 & 13, 2005 Dalhousie University, Halifax, Nova Scotia This special two-day event promises to become an annual gathering of evangelists, recent converts and the open-minded to explore the challenges and the future of the Open Source movement. CEOS is organized by the Dalhousie Student Chapter of the Association for Computing Machinery (Dal-ACM) and aims at: * Showcasing the open-source projects undertaken by universities, government, industry, and the community * Enhancing the knowledge and exposure of open-source software * Promoting stronger relationships between academia, government, and industry in the form of open dialogues and open-source initiatives This year's highlights include: "Exploring this business of Open Source" is the subject of a presentation by Dr. Brian Barry, who is currently CEO of Bedarra Research Labs. Dr. Barry has over 20 years of experience in the design and implementation of component-based and object-oriented systems and led the development of the Eclipse Platform and IBM VisualAge at Object Technology International. Billy Biggs, a Master in Computer Science from Dalhousie and an active developer of the open source Eclipse Project at IBM Canada will address the philosophy and politics behind the open source movement and explore the real, seemingly altruistic motives of developers. The Vice President of Sun Microsystems operating platforms group, Tom Goguen will give a provocative presentation entitled "Open Source, Open Standards". An analysis of the benefits as well as the pitfalls of developing products that incorporate open source software will be explored in depth in a presentation by Dr. Lawrence Rogers who is currently the Chief Technology Officer of Bandalong Incorporated. Dr. Rogers has over 30 years of experience in the software industry from the heavy-hitters to a recent string of successful start-ups. Richard Charpentier, a specialist in infrared imagery and space-based surveillance at Defense R&D Canada - Valcartier and an advocate of open source software within the Department of National Defense will address the reliability and security considerations as well as the strategic value of adopting open source.

Visual Intelligence

Gilbert's very interesting talk last night reminded me of a book I read a few years ago on the rules that our brain uses to create what we see. It was a fascinating read. http://www.cogsci.uci.edu/%7Eddhoff/vi.html He has created a number of Java applets to demonstrate how we create the motions that we see. http://www.cogsci.uci.edu/%7Eddhoff/vi6.html -- Bill
