When you use a credit or debit card at an ATM or in a store, a good chunk of those transactions now go through the internet. In 1995, they all dialed up/used leased lines to a packet switched network (DATAPAC, TYMNET, etc.) or a terminal bank. Your hypothetical Sally/Sam the Wallmart Greeter who doesn't use the internet works at a store where ordering, inventory, POS and other essential activities require an Internet connection.
Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
Modems are/were rated in actual bits in decimal with no base-2/base-10 shenanigans. So 56k was actually 56000... Or more then likely you actually got 44000.
Not nearly as bad as the Sunday Times article...
2450DPI on an inkjet printer is almost always a marketing number. Usually, they consider the dyes/inks separately. The paper itself can't deal with points that far either. The purpose of having higher DPIs on a printer is:
(b) Reducing the visibility of the pixel artifacts (i.e.: supersample, blur, spray on the paper).
Specific special case. Basically large 3D matrices of doubles.
3D MRI registration using X-correllation as objective function as implemented by DL Collins et al. It's available as part of the MINC package.
Fink and MacPorts both have the same problems:
1) It's impossible to successfully compile anything complex with 64-bit compiler flags (i.e.: -arch x86_64 -m64) since all libraries will be built without said flags... So you have to manually figure out all the dependencies yourself or backtrack the 32-bit install piecemeal.
2) X11 is/was often broken and needed XFree86 compiled instead of Apple's X11. This might have been dealt with in all cases now.
3) They are hopelessly behind every major O/S release. It took forever to have a 10.5 compatible fink and/or macport that was officially released.
All in all, I had to build a 64-bit application chain for 10.5/Intel and it took me two days to get ~30 packages compiled and linked successfully and fink/macport couldn't be used. I often had to reverse engineer fink mac patches for the packages that it did have, it's silly that I couldn't use fink to build them in 64-bit!
The rationale for a 64-bit build was a 40% performance improvement.
Yes because you calling your grandmother to chit chat using VoIP is far more important than me sending Magnetic Resonance Imaging files to India via FTP.
If you need guaranteed bandwidth, you buy it. We receive hundreds of MRIs per months at work and we don't have a residential DSL. We have an optical fiber link (GigE) with an ultimate "Internet" (for what it's worth in a BGP world) link around 300mbps 95-percentile. Guess what, we get our contracted bandwidth... All the time. It's not exactly cheap though, but then we're not downloading porn torrents...
