I was going to say, ATM/PPPoE encapsulation is approximately 15% of total traffic. Bell Canada and all providers do that up here. I thought everyone knew this, or were able to google it especially if they are able to upload something like DDWRT to their router. Perhaps I had too much faith.

We're using this. BES5 server for the old devices. BES10 BDS (BlackBerry Device Server) for a couple Q10s and a couple Playbooks, then UDS (Universal Device Server) for a bunch of ipads. All three servers are managed by one interface, Mobile Fusion. For us, it's not about "hey, apple has this" or "hey android already has this" it's about "hey, I can manage these all from one console". Saves a tonne of time, and a tonne of hassle. I am not super happy that with BDS/UDS they moved to Active Sync, but our AS Server is behind a firewall and we have the UDS devices set to VPN in automatically to get to it. The BDS devices are "in the network" like the old BES stuff and don't need a VPN. Hell, I had a case open with BlackBerry as I needed RRAS and the UDS/BDS working on one server, long story short, it looks like a KB article will be made based on that support case.

Yeah, I'm going to have to call complete utter bullshit on that one. There isn't a UGLE recognized jurisdiction in this world that does any sacrificing of animals or humans, dead or alive. And I doubt any of the clandestine lodges (not real Freemasonry lodges, but ones that purport themselves to be) do either.

Actually. CB Radio is outlawed as well. I know, I have one and I feel like a rebel using it HAH!

In seriousness, the ONLY exemption to CB radio is (and I am paraphrasing here): Truckers and delivery vehicles *performing* their duties while on the clock, other highway maintenance agencies *performing* their duties while on the clock, and HAMS. As a normal person, unless I have an *valid* Amatuer Radio License, I cannot use my CB. (I don't have a valid HAM license).

No way! I was on the board at Friendship's installation last month of the new WM. I'm the WT go-to guy it would seem ;) Actually, having said that, there's a Friendship up in Sudbury, ON too. Could be either one I suppose. Crazy if it's the one in Pickering/Toronto... that would be a small world.

Instead of saying "District 3" I should have said "East District" - they redrew the boundaries a few years ago. I always forget. My bad.

Ok, here's my take as a Canadian trying to pickup American stations and Canadian ones as well (who just spent the better part of last night up on the frigging ladder in -20C weather trying to get his damn preamp going)...

Bowtie is the way to go. Channel Master 4221 for suburban/urban areas and 4228 if you're out farther. The latter is more directional and doesn't pickup the side lobes as well. I'm 35Km from downtown toronto (20 miles or so), and much farther from buffalo and rochester NY. With a 4221 I can aim just west of Buffalo and pickup nbc/abc/cbs in full HD glory. My side lobes pickup downtown toronto and rochester.

The poster who pointed out a silver sensor... no good for anyone outside say 15 miles or so. I got one as a freebie when I picked up my samsung hd converter (I only have an hd ready crt projection tv)... he gets... nothing on his brand new 6th generation atsc chipset tv. Well, not nothing, but very little. He gets some of the toronto stations and can barely pull in NBC from buffalo. I ended up gifting him my old 4221 clone for the superbowl, and now he gets most of the stations I get, but is still missing out on some toronto stations.

So, I can say from experience, that the bowtie is the way to go. Which one depends on how far you're trying to "reach" out into the ether.

I can pull in Fox, CBC and CTV with a frigging paper clip attached to my antenna port. The rest, need a better antenna and sometimes even a preamp like in my case. I even tried building a gray-hoverman, and while it was OK, it was far too rickety to put outside. I tried those RCA loop/rabbit ear antennas amped and not... no good whatsoever unless you live right near the transmitter.

Up here we don't need to worry about VHF HI, so the bowtie works fine. But those old huge antennas still work... as long as they are rated for UHF and not VHF (or also VHF if you need VHF HI).

A yagi is great, but is far too directional for most applications... even on a rotor... most of the new boxes and tv's need to be rescanned every time you move it... annoying and takes 2 minutes or so. Good luck using that as a selling feature ;)

My other neighbour has one of those big antennas on a rotor, and his reception is piss poor and it's rated for UHF. The problem is... UHF goes less distance, but is better at getting around objects blocking your path. In his case, we;ve upgraded all the cabling, but it's proably his 4th gen converter box... the newer 5th and 6th gen chipsets have much better mutipath interference rejection which is essential for uhf, and can also work with weaker signals.

Long story short - people WILL need new antennas depending on where they live, and yes, going up a pole requires some scary freezing cold cojones in the winter. I've been doing it for the past few days tweaking my setup and let me tell you... it's not fun. As much as I am not affected by the american switch (aside from reception hopefully getting better once the analog stuff stops interfering - I hope) - this switch will let those in colder climates hopefully NOT have to get up on the roof in this weather.

And, I don't have cable nor satellite. Been free of those expenses for a year or so now.

That distinction belongs to the Motorola Marco, an early licenser of the Newton platform. Another, less ambitious product to merge wireless and an Apple-OS was the PowerBop network in France.

A 3D Printer On Every Desktop? 426

holy_calamity writes "Two Cornell researchers have designed an open source 3D printer that costs just $2,400. The self-assembly kit is part of what they call the Fab@Home project — they hope it will spark development of rapid prototyping for the consumer market in the same way the Altair 8800 did for personal computing in seventies." Here is a video showing a completed machine constructing a silicone bulb (16-MB WMV).

Interestingly, this all happened before the Eagle Nebula was discovered by Jean-Philippe de Cheseaux in 1746...and we won't actually see it happen here on Earth for another thousand years or so. From the article: "Humans living 1,000 to 2,000 years ago might have noticed the supernova event that destroyed the pillars as an unusually bright star in the sky. We have checked with historical records, and there might be some candidates.""

A Fully Programmable Mobile Robot 86

paxmaniac writes "iRobot has announced Create: a new fully programmable mobile robot based on the Roomba robotic vacuum cleaner. People have been hacking the Roomba since the day it came out. Well, hacking just got a whole lot easier. A command module for the Create provides a programmable 8-bit Atmel micro controller, four DB-9 ports for your own sensors, and a number of sample programs that can be compiled and uploaded to the command module via USB. Botmag has more details and some cool applications. This looks like the perfect robotics platform for hobbyists, schools, and universities alike."
