Re: chromium error: Error initializing NSS without a persistent database: NSS error code: -8023
Yuwen, ] I'm using Wheezy and chromium. Chromium has been working well until ] today. When I ran chromium from the shell, I saw this message: ] ] [31:31:1029/204029:ERROR:nss_util.cc(211)] Error initializing NSS \ ] without a persistent database: NSS error code: -8023 ] ] and chromium can't open any page.

Re: Entropy (was Re: how to generate random negative numbers)
Ron,
John Hasler:
] echo $(( $(( $RANDOM - $RANDOM )) % 3 ))
Ron Johnson:
] Does this burn through entropy faster than other methods?
Yes. Twice as fast. And, more importantly, it's mathematically
incorrect. It does not have the same probability density function as:
echo $(( $(($RANDOM % 5)) - 2))
To illustrate, assuming that each $RANDOM value is uniform over {0,1,2}
mod 3, here is the table of the function b-a:
b
+-
| | 0 1 2
+-+---
|0| 0 1 2
a|1| -1 0 1
|2| -2 -1 0
5 (the number of values in {-2,-1,0,1,2}) simply doesn't divide 9 (the
number of values in {0,1,2}x{0,1,2})
(Also, remember that when one adds multiple random deviates, as the
number of deviates approaches infinity, the distribution approaches
Gaussian. Here, with two deviates, one ends up with a triangle
distribution.)
Programmatic cleverness sometimes works, but it's a sharp knife. One
must be careful not to accidentally cut oneself.
Regards,
Eric

It's simple, and simple is good. Another problem with a ps(1)-monitoring solution, besides the one Douglas points out above, is that it doesn't scale; a script that uses ps(1) can't be run concurrently in multiple directories, should your requirements eventually expand to include that in future. Your solution, Kamaraju, can. Nota bene: Just as in recursion one tests for the stopping condition first, at the top of the function, I presume you're remembering to test for the existence of these semaphore files before launching proga and progb, and doing the right thing (however you define that, e.g. not proceeding at all, or alternatively just removing them and proceeding) if they're already there.

screen grab of scrolling window?
Hello, I have an on-screen image that, unfortunately, is not all on the screen; it's too big to fit on screen and there are scrollbars for me to scroll to view this and that portion of the image. Question: Is there a program that can perform a screen dump or a screen grab of a scrolling window, to convert the entire contents (i.e. not just the on-screen contents) of that window to e.g. a png file? In this instance, the image in question is that of an emailed PDF document created under Mac OS X; I want to be able to grab/snap exactly how the document looks under Linux here and send that grab back to the creator. It turns out that ImageMagick's convert(1) program almost but doesn't quite do the trick; what it does is shrink the image down to my screen height first.
