Hmm, replying to my own post with a correction I noticed when I re-read after posting, before some uber-network-guru calls me an idiot...
I can download from Hayes, Iowa, at 15 Mbps.
Your maximum speed has nothing to do with latency, which is what the ping time is measuring. Most protocols adjust for increased latency, so even on a satellite connection with a 1s ping time due to physical distance, you can still get many Mbps on a large transfer. Response time for anything interactive is a completely different story.
6ms until I hit savvis then its 80+.
All of the physical distance is probably on savvis' network then... Why does that make them suck?
I tested three different connections at the same location here in Calgary since I have all three available here in the mini-NOC for troubleshooting when parts of the internet melt, a 25 Mbps business-class Shaw cable, a 6 Mbps Telus ADSL2+ and one on our own in-house DSL equipment running at 3 Mbps backhauled via fiber that eventually peers upstream with both Telus and Shaw... Local IPs have been hidden...
These were each tested directly from a FreeBSD router to the appropriate modem.
*** SHAW
As I expected, despite having the fastest rated "speed", the Shaw connection's LATENCY (which is what we're measuring) was the worst (don't read too much into hop count on today's backbones, ie. here we happen see many of the hops inside level3, including several which did not increment the hopcount, but many backbones will not show (m)any depending on their transport, design, etc.):
Ping times vary, usually 90-100ms but as usual on cable, sometimes they spike WAY up, even on this "business class" network version:

Here, I happened to catch some suckiness for a few seconds (ie. why cable generally is bad):

(Actually at least 20 hops on visible, responding routers , though it shows only 15)
*** TELUS
The Telus was second and has the shortest number of SHOWN hops, but there are many pieces of equipment between here and slashdot, they just don't show up:

***SATURN
Our network adds a couple extra hops and the test link is 3 Mbps vs 6 for the Telus but since it ends up routing these packets through the Telus backbone upstream, performance is similar but ends up being a TINY bit faster despite the extra latency on the DSL line because our internal network is less loaded and very carefully controlled:

YMMV
I was dismayed to see this article in the paper today:
I didn't think we'd (Canada) be stupid enough to actually go through with this new copyright bill, but it seems that it has.
My favorite was the Dataproducts B-300/600 band printer... We had one of the 300s at the office until the early 90s but it had an uppercase-only band and PROM in it so it did the 600 lines per minute like the LBP-600 could do with the upper/lower case band... Man, did that thing ever have a fast paper feed on it... I think the 600 LPM rating was for full 15" wide printout, full character lines because it sure spit out the average page of text much faster than 10 pages per minute (Unlike today where you'll rarely see the "up to X ppm" in most usage)... Made the neatest cha-buzz cha-buzz noise when printing, too... What a beast! I can only imagine the 2000 LPM and faster models... I miss that thing
Actually, flatbed plotters were quite nifty little units back in the day... The big roll-types are still used today for large-format schematics, drawings (floorplans, etc.), or really anything vector/wireframe works very nicely on a plotter... SUPER slow, but you're not usually doing a lot of copies...
You could also mount a spindle and motor in your 3D and engrave everything onto the material of your choice... That's always fun....
Where can you find a 27X cartridge for $20? Around here they are about $200 for the HP original, and about $150 for a re-manufactured/refilled... Certainly not $20...
I'm surprised more people here don't still use a dot matrix... Very low cost per page for general output compared to laser or especially ink-jet... I have lasers and ink-jets too but my go-to printer for most stuff is still my trusty old Okidata 393C color 24-pin dot matrix... (Actually I have 3 x 393Cs and a B&W 393... Spares I've aquired each time I ran across someone else was retiring one, but my original one's never had a problem and I think we got that one in 1988... LOL) That and the LaserJet III are probably my favorite printers of all time... Indestructable. I have a LJ3 here with almost a million pages on the engine... Still works when I can get decent toner cartridges for it...
Your stupid conception of the world is shared by many people, so I won't blame you for repeating BS.
I will however laugh at you for being Canadian.
Ditto.
We all know the USA is far and away the best country in the world, by all metrics in all categories.

In the only episode of that "Are you smarter than a fifth grader?" show that I ever watched, the contestant honestly didn't know what country was located to the north of the United States. (To be fair, all the 5th graders did...
Yes, thank you... I was meaning "we" when I said North America; my point being it's not just the USA that seemingly doesn't manufacture as much, and yes I'm fully aware that "we" still manufacture many, many things, but it at least seems to me that we've outsourced many types of production to the point that we almost don't remember how to make them... Consumer products, etc. especially... How many "regular" consumer items that you buy lately have a made in Canada/USA/Mexico label on them? My T-shirt was made in Bangladesh, my shoes in Vietnam, my Dodge truck which was assembled in Detroit has a Nippon-Denso alternator and starter, not the USA/Canada made Mopar parts like my trusty old maxivan, etc. etc. etc. ad infinitum... My 20 year old 4800W garage space heater was made in Canada, and it still works perfectly after thousands and thousands and thousands of hours of use... The company still exists, making large ventilation fans and such, but doesn't make things like $50 heaters you buy at Home Depot / whatever anymore... I've repaired a friend's "made in China" similar model thrice already and it's only 2 years old.... Regardless of how much we "still manufacture" it SEEMS to ME that some things have really been lost. YMMV
North America has generally seemed to have forgotten how to actually build things. I'm located in Canada, and on those few items my tiny company makes, I'm proud to put the stamp and seal of where it's made on my products...
isn't it?
Actually, I believe it started earlier than that. Harper may have started the "privacy" stuff
It wasn't the Harper government... The Liberals tabled far wider reaching anti-privacy and oversight legislation!! It was the conservatives that avoided that only to now bring their own only-slightly-less-ridiculous bills...
And web developers won't care. I think this is an important note. Old IE users (6/7/8) make up a large enough chunk of the web that legacy support for them is considered a higher priority for most, but FF 3.6 users are very much a minority, so you can't expect any support going forward.
Web developers are a huge part of the problem (as was/is IE in general). The whole idea of HTML in the first place was that the browser shouldn't matter... You should be able to render a reasonable version of a page with any browser! That hasn't worked for a long time and the content is mostly to blame. It should never return different data depending on what browser you use. It shouldn't have to by design... but it's broken!
