Wiring for data in houses

Hello everyone, This is only loosely related to Linux, but it is certainly related to home networking in Ontario. I'm looking for some of the "offical" information about how to wire data wiring in houses legally. I know, every guide says use plenum-rated wire, and I know there are tricks to prevent interference etc. But what I really want is just the authoritative information about what the requirements are in Ontario. Is it really that simple? I'd hate to wire it up only to have somebody need to rip it out in the future as a fire hazard. I was thinking of cat3 phonewire, 2 sets of cat6 data (material costs are less than the work to install it), and some cable tv coax and speaker wire. I was also thinking of some interesting data jack locations for outside network-enabled cameras, wireless access points and wiring closets. Rumour has it that people are also wiring in fibre these days, even if it is unused. Unused cat6 pairs could also be used for home automation, or who knows what else. Wireless is not going to be a perfect replacement for this stuff for a long time, today it is slow and suffers from privacy issues. Tomorrow it will be faster, but whether or not it will cater to impractical geeks remains to be seen. Besides, it's fun to hack around with this stuff. Another reason I want to do this however is because it is an old house... I'm going to be doing some electrical & plumbing upgrades, and afterwards, I'm going to be using some blow-in insulation for energy efficiency and soundproofing... which will make future wire installations an order of magnitude more difficult. The thought also crossed my mind to use armoured cable and carefully placed pull-locations, so that some nut in the future can wire up their post apocolyptic EMP resistant pneumatic computer networks, or whatever other oddities appear. Most of the work will be done next year. Currently, I'm researching so that I can plan things out reasonably well. I'll probably be doing a couple small runs in the next month or two, if they fit a master-plan, all the better. -Mike -- The Toronto Linux Users Group.

You really have to consult the fire marshall or the building inspector's office on this. AFAIK plenum cable is only necessary if you are breaching a "fire barrier". If you are gutting the interior walls of the house, you may want to string conduits to plan for future use at the same time. We've been stringing cable for a couple years, and have been told the rules but have yet to be referred to any documentation on it. Since there's no electrical load, the consensus has been to use plenum when breaching a fire barriar or going between floors, and outdoor cable if slinging alongside the building for those hard to reach drops. -- Keith Mastin (416)429 9304 -- The Toronto Linux Users Group.

DVD Burning and Viewing

I did try to run Ogle from the command line in an x terminal as >suggested in a goolge search. Ogle is the DVD player software I have tried to use. It was the first one I read about that was supposed to be able to play encrypted discs and was supposed to have support for the menus on the DVD. Whether it can play a given DVD or not seems to be a bit of a coin toss. Some times it will work and sometimes it won't. Depends on which DVD you give it and what features the DVD uses. The program seems to choke at start up (ie. before it gets to displaying the DVD's menu) with some DVDs. I haven't tried Xine for movie or DVD playback yet. The one other observation about Ogle is that its playback seems to need more CPU horsepower than the PowerDVD software I use in Windows. PowerDVD is just able to play DVD's acceptably on my Pentium II 266MHz machine. With Ogle under Linux the video playback starts dropping the odd frames which is just barely noticeable. >In regards to burning. I know K3B is pretty good as is CDrecord from the >command line. Any other suggestions ? When I first got a CD Burner, the burner software made the Windows side of my machine unstable so I tried burning under Linux. I XCDRoast for burning these days and it works fine. The alpha14 version (IIRC) had experimental support for direct support of IDE-ATAPI drives but the latest alpha15 version has dropped that for some reason. If you are using IDE drives, you need to tell the kernel to use the ide-scsi module for the (hdc/hdd) drives. In XCDRoast, you would select the SCSI versions of your drives as the ones to use (it will show you both the IDE and SCSI versions). Also, since you have DVD writers, you can get the ProDVD plug-in for XCDroast which allows you to write to DVD disks. If you check last months Linux Journal they have more information on software to make the image files for a DVD. Cheers! Kevin.

It is the first one I found (I didn't like raw gdb either). It isn't perfect but it sure makes code development a little easier. Depending on what you are doing, there is also the possibility of using something like RHIDE which is an integrated development environment similar to the old Borland IDE. Cheers! Kevin.

My main aim is to understand the workings of the kernel a little bit better. For this reason I would like to verify what is stored in the first few hundred memory locations. e.g in x202 the signature HdrS is supposed to be stored. So to answer your question: Any which way that would get me on the screen the memory content of preselected locations would do. Jing Su has pointed out one way to accomplish this. My C programming is rusty and it will therefore take some time to follow up his lead. Any other suggestion will be very much appreciated. Thanks, John -- The Toronto Linux Users Group.
