Software Engineer & Architect & Evangelist & Pundit & Skeptic

Started with Unix in 1984. I have no recollection of what version but was labeled IBM, maybe a Unix-style shell on mainframe?, then to Apple ][ (who didn't?), Windows, Linux and AIX in 1993, OS/400 in 1997. Back on Windows now as a client only to my Linux boxen in the "cloud."

comment What are the Windows A: and B: drives used for?
@Joe, the difference is due to constant angular velocity on the drives vs. some who slowed the speed at the outer edge to achieve marginal increase in capacity.

No, D was not the CDROM. D: existed way before CDs were commonplace.

comment Which is the fastest Linux hypervisor?
@quickly_now, what are the utilization #s on the instances? My guess is they're far from being daily 80%+.

comment Which is the fastest Linux hypervisor?
@Jason404, data was on SAN, not sure of your question. BUT: compare DASD v. SAN IO, SAN isn't the bag of chips it is made out to be.

comment Which is the fastest Linux hypervisor?
I've deployed countless instances of our classical software stack on various VMware instances (each >5k concurrent users). I have never seen them perform even close to bare metal or LPARs. It is fine software, just IMO far from being capable to support what is needed from IO spin locking.

comment Control-Backspace (unix-kill-rubout) for readline?
Hi, .inputrc actually says unix-kill-rubout, I don't know why I kept thinking it was unix-kill-word. Regardless, it still just asks like regular backspace.

comment Linux: obtain current # of jiffies since reboot
Appears as though any given time delta is not consistent with a sum across the /proc/stat!

comment Linux: obtain current # of jiffies since reboot
How does one activate the timer_stats? Correct, the 'jiffies' is an arbitrary increment in this case as long as the various /proc/PID/stat files report a metric that is equivalent to some total I can use to calculate relative %s. OK, so there is a "jiffies" line in /proc/timer_list, I'll update original post.

comment Linux: obtain current # of jiffies since reboot
Right, but to find the total # of jiffies since start, would one not do something like awk '/^cpu/{print $2+$3+$4+$5}' /proc/stat?

Is this not only for user time for which the cpu was scheduled? The others being nice, system & idle?

comment Why can't Unix users renice downwards?
Should we not consider nice values [-20,-1] to be system priorities vs. the user 'space' [0,19] I get what you're saying but I'm of the recent persuasion that user processes should be able to re-prioritize themselves or their children...at least from a base priority set by root?

comment Why can't Unix users renice downwards?
Not necessarily. For instance, user renice could not drop below 0.

Kermit appears to be working the best over here.

comment Windows registry entry for swapping tilde/backtick and escape keys?
I like that it isn't a service or program, but just sets the registry. Let me take a look.

Locks up everytime when running under XP (although it said it might when it started).

You have a good point about the power draw. That ps/2 brings back so many memories of programming :)
