several other equally useless keys could be removed just as easily. Caps Lock, Num Lock, PrtScr/SysRq, Scroll Lock, Insert, and the entire keypad that activates with num-lock.
With so many keys reduced, maybe we could get keyboards to be a buck or two cheaper and less intimidating to new users...
Quite interesting... Uranus' moon is part of the ring - the particles are hitting it - and the moon is slowly disintegrating. Wonder how long it will take for the moon to completely dissolve into the ring.
I work at a lab where we use Sun SPARC hardware running solaris for most of our simulations etc. Recently we bought two windows boxes from dell - for variety, compatibility etc.
One fine day, I was doing some experiments inside the lab. I came to my sun machine to check email - the screen was frozen. The mouse would not move, the keyboard would not type. I tried ssh'ing in from outside and killing rogue processes, but that would not work. There was absolutely no response from the machine. Finally I decided that it was time to reboot. I switched off the machine - it never turned on after that. I ended up wasting days - doing power-on-self-tests etc and finally found out that the CPU was bad. The machine was two years old - out of warranty. A refurbished cpu would cost about $550.
So my boss said that I should install linux on one of the new pc's that we bought - and get back to work.
Well, the new pc happened to have a SATA hard drive. SATA hard drives are supported only in the most recent kernel versions. After a couple of weeks of going through all kinds of forums, google searches, buying a new IDE hard drive, recompiling kernels, tweaking things - I have gotten the box to work.
Nett result - I wasted about three weeks of time, invested way too much of anxiety and effort.
The linux box works, though. It has been pretty stable so far - and hopefully I won't have to do computer repairing for many months to come.
My iBook has treated me surprisingly well, though. Two years - and very few hiccups.
The OS is not the issue at all. Here we are talking about the logic circuits. One can always keep a clock to feed the OS. In an asynchronous circuit, the latches will not be clocked with that clock. That saves on a lot of power issues. On the other hand, in a synchronous circuit, all the parts of the circuit will be clocked by the same clock - which goes through an immensely complicated clock distribution network.
