The last mile for the Level3 is coming on Telus (after a punch to the face and gut for build out fee) so I'd like someone else. Shaw does not offer service without what I suspect is another punch to the face for a build out. Bell didn't return any of my inquiries via email of voice message.

no no no.. it's simply, since the OP posited a math solution, md5. ship the size of file + hash, compute file on the other side. All files can be moved anywhere regardless of the size of the file in a single packet. MD5 compression is lossy in this context. Given big enough files you're

s...@cs.columbia.edu: I am seriously suggesting that a redirect mechanism -- perhaps the email equivalent of HTPP's 301/302 -- would be worth considering. We already have SMTP's 221 and 521 response codes for this. But because the response text is free-form there's no way to reliably parse out

I have a client in Edmonton who's looking for a network drop to their office, something in the 2-10 MB/s range. The location is at 46 Ave. and 99 St. The core requirement is for a bare unfiltered *symmetric* pipe (no ADSL). Traffic volume will be low: 2-4 laptop VPNs plus some light web server

Barry's right, for at least some scenarios. If I have an unauthorized somebody walking down the row with a wand in their pocket, the fact they have a wand in their pocket is the least of my problems. Encrypt the data?

RFID tags are generic, you don't put data into them unique to your application. Field programmable RFID-like tags do exist. They aren't common, but they're out there.

Rogers says they don't do that, and lots of other people seem to be able to use port 587 on Rogers (and other ISPs) without problems. I'm in Calgary right now so I can't check the current behaviour, but as of June 1st it was still broken. Broken in the sense that any connection to port 587

Re: ISP port blocking practice

2009-10-22 Thread Lyndon Nerenberg (VE6BBM/VE7TFX)
Few companies use the MSP port (tcp/587). Can you elaborate. Is this based on analysis you've conducted on your own network? And if so, is the data (anonymized) available for the rest of us to look at? My experience is that port 587 isn't used because ISPs block it out-of-hand. Or in the
