comment Windows 7 boot process is completely dead
The 'bottrec' command completely wrecks things, didn't you know? Or maybe this is what happens when you do something like replace Linux with Windows. The interesting question: is it Windows 7 refusing to have anything to do with a machine that's had Linux on it, or Linux wrecking things so that Windows 7 has no idea what to do with it?

comment linux: how to run a command in a given directory
And the other reason for running a shell script from the crontab file is to ensure that the environment is set correctly. The environment given to a cron job is normally barely even minimal, so you usually need to reset it to something more usable.

I have a feeling that a lobotomy performed with a 0.44" calibre firearm would be both quicker and less painful.

comment Safely get rid of “You have new mail in /var/mail” on a Mac?
I checked - I had 210 messages waiting, the latest from January 2006, which is before I bought this computer! The data transfer service was thorough. I used d 1-210 quite successfully. I didn't have anything reminding me, though.

comment ~/.profile does not run on startup
@Dennis: AFAICT (and certainly as I intended), I said nothing about the alias being exported or exportable. You are right that not every variable needs to be exported; again, I did not say that they should all be exported. It depends on whether @pocoa has any use for the variable other than in the alias. My suspicion is that it might be generally useful as an exported variable, but that is not inevitably the case.

comment Linux Directory Access Problem: Permission Denied “”“In Root”“”
That's an unusual permission string; the dashes should be missing. Also, NEVER have public write permission on the root directory.

comment CPU I/O communication
@b-gen-jack-o-neill: for an IN or OUT instruction, the memory would (normally) ignore the request because the I/O pin is asserted. With memory mapped I/O, there is no RAM at the address - the I/O device is mapped there. So, the net result is "no, what is written goes to the I/O device". If someone misdesigned the memory system, I suppose you might have memory paying attention to the I/O request, but chaos will ensue -- does the I/O device or the memory win on an IN instruction where the memory tries to provide an answer as well as the I/O device. It won't work, and hence you won't see it.
