Just learned how to save about a bazillion keystrokes over the remainder of my file-editing & programming life.This is because I just learned that C-M-l (or Control-Meta-l, where "Meta" is the "Diamond" key on a Sun keyboard) is the (X)Emacs key sequence for "switch-to-other-buffer".I have been doing this via Control-x, "b", Enter, or in other words, switch-buffer, then pressing Enter to accept the default, which has the same definition as "other-buffer". And I do it all the...

I regularly do a full install of a Solaris Development release onto mylaptop. Why full? Well, that is another story for another day, butit is not because the Solaris Upgrade software; including Live Upgrade;is lacking.I decided I no longer see the sense of burning a DVD to do this; and Iknow that Solaris can boot from a USB device.I used James C. Liu's blog as aninspiration, but the following is what I have found worked well toboot an install image located on a USB disk. You...

I'm the kind of guy who likes to tinker. To see under the bonnet. Iused to have a go at "fixing" TV's by taking the back off and seeingwhat could be adjusted (which is kind-of anathema to one of thephilosophies of ZFS).So, when I have been presenting and demonstrating ZFS to customers,the thing I really like to show is what ZFS does when I inject "silentdata corruption" into one device in a mirrored storage pool.This is cool, because ZFS does a couple of things that are not...

These things are true, but I hope thisentry will be of interest anyway.I am still a habitual user of the "man" command in Solaris (and otherUnixes). It has pretty good response time, and the format isfamiliar. I did notice a number of years ago that the format could bebetter. All sorts of terminals are able to display...
