This is not a problem on MacOSX macosx knows what is exacutabele and not. Not sure though if this applies to CLI based applications and scripts.
I believe Mac OS X recognizes executable files in much the same was as Linux/Unix does, via the file permissions. Here's the file permissions for the Mail program.
ls -l/Applications/Mail.app/Contents/MacOS/ total 11648 -rwxrwxr-x 1 root admin 5962096 Jun 16 15:18 Mail
The Shuttle uses 5 computers, all based on IBM 32 bit CPUs (see link below). You can rad-harden a general purpose CPU chip though it is an expensive process.
You only need 5 bits to code all the capital letters. Do a search on Baudot, the character set used by teletypes. It was quite innovative for its time and is still in use for TTY access if I'm not mistaken.
By the way, 16 bit machines predate 8 bit memory modules (hardware chips) by quite a bit. The old Honeywell 316/516/716 series were 16 bit computers and used core memory. BBN used them to build the IMPs used for Arpanet.
In order to use a USB device with Win95, you've got to have a driver written specifically for Win95. Not many manufacturers supply such drivers since the Win95 support wasn't terribly robust and even Microsoft recommends against using it.
It's officially known as ITU G.992.2, and most places don't bother to tell you what particular flavor ADSL you're running -- they'll just tell you a bandwidth number. Wheee.... The main point is that it's splitterless at the consumer's end of the line.
Both G.Lite and G.DMT (full rate) can be run splitterless. DSL CPE equipment vendors (and the ILECs) have been trying to sell consumers on user installed equipment. You can overcome noisy POTS equipment in the home with judicious use of microfilters. Newer POTS equipment typically doesn't bleed over into the low end of the DSL range.
In practice, I understand G.lite and full rate DSL are very similar in processing burden, and that the main difference is in how they're tuned. Full rate DSL is tuned for high speed transmission, at the expense of making retraining more expensive (since it doesn't expect to retrain often, as you mention). G.lite runs somewhat slower, but offers fast retrain to handle interruptions on the line, and also to offer lower-power modes that basically "hang up" the modem. The drawback is that you don't get as much bandwidth to play with.
True... since most people live too far away from the CO to get anything greater than the 1.5 Mbps maximum rate which G.lite offers, the computational difference is probably moot. When I stopped working on ADSL modems, it looked like a number of the G.lite features were working their way into the full rate standard. I think eventually the only difference will be maximum data rate.
