Is it possible to show the number of unread Gwibber entries in the me menu? And is it also possible to open Gwibber or Empathy from the me menu? Not just the preferences, but for example for Gwibber the whole window?
View 2 Replies View RelatedIn the last week or so, I've frequently been running out of X server client connection slots and getting "Maximum number of clients reached" errors. For example, I'm getting it right now and I'm running 3 pterms, Chrome, and Thunderbird; I've even killed my panel. 'xwininfo -root -children' produces what seems to be an absurd number of X clients (150-ish, when it's able to make a connection), even immediately after Gnome/Xfce startup.
It doesn't take long. A day at most. I've had this system up and running for months, and this just started happening. I did install some X development libraries (x11proto-core-dev, libmotif-dev, x11proto-print-dev, and x11proto-xext-dev plus their dependencies) about two weeks ago, but this problem has not been happening that long. I've installed other packages, but nothing that would seem to have any relation to this problem. I've logged out and in, rebooted, and changed from Gnome to Xfce, and none of the changes helped.
how many clients (pcs) can be tied to a U1 account?

When i tried to run from terminal, it will give me an error like this:

I checked using
Code:
And i got around 234 which is too much that it takes almost all of the open files allowed. Logging out to text and brings back X will solve the problem, but it's only a temporary solution until X opens more sockets again. I'm running -Current (32 bit)
It seems that there's a hackish solution in here: [url]. Dunno whether it's a nice solution or not, but i'm willing to try it.
# echo "foobar" > /tmp/word
# cat /tmp/word | wc -m

I want to print the number of characters in the file. Why does it output 7? Am I missing something obvious?
manpage:
-m, --chars
print the character counts

View 6 Replies View RelatedI'm trying to find a script that will return me the largest number of repeating characters. Say, I have the following line in a text file: 12345AAAAA6789AAA
I want it to return 5, because "A" is repeated 5 times in this line (more than 3 at the end).
How do I count the number of occurrence characters in a string in an efficeint way ?
How do I reverse the words in a string with out using temp variables if possible . (if not possible use temp variables ?

Ever since upgrading to Fedora 14, my system has been almost unusable. I can only have a few windows of anything open before I start getting messages about:

I am unable to open any new windows then and lots of programs crash.

I'm attempting to search through a rather large assortment of html files created in Word using 'save as html'. what I'm trying to do is find and delete these tags (they're causing browsers to display black diamonds with white question marks):
<span style='mso-spacerun:yes'> </span> Tags contain from 1 to 4 spaces between opening and closing. I get positive results from this:
grep <span style='mso-spacerun:yes'> filename.html but once I attempt to tell it to match any number of characters up until the next '>' symbol, it tells me I'm using an invalid regex: grep <span style='mso-spacerun:yes'>[^>]+> filename.html
I've been nose-deep in regex tutorials for the past day or so, and I'm still not understanding why this doesn't work. If I put the pattern (without backslashes) into a separate file and use `grep -f patternfile filename.html`, I get no error but no matches either. So far as I can figure, the above regex boils down to:
Match the string "<span style='mso-spacerun:yes'>", followed by any number of characters that are not a ">", followed by a ">". If someone could tell me where I'm going wrong with this,
I have a running proxy server that I wish to also turn into a VPN server.The VPN is not used so much that a user can access the network but is used so that they can obtain a geo specific IP address for their applications (the proxy server only does this for HTTP).I would therefore like to block off the VPN from accessing any of my Linux box's ports such as email, web server etc.Clients are given local IPs of 172.16.0.x.What should I take into consideration to block off clients from accessing dangerous stuff on the network?
View 4 Replies View RelatedI got some entries in my auth log that I am puzzled by. What could be the cause? I was not using my machine at the time of the logging.
Code:
Like many (most?) home users, until now I've had my regular userid in sudoers as "ALL = (ALL) ALL". It occurs to me that, even though my machine has no open ports, this is probably not a good idea - just in case my firewall suddenly burns down. So, if my thinking is right on this, I'm wondering if there is a generally approved list of Cmnd_Alias entries? At this point, I've decided to only add entries as I use them, and to try to honestly appraise my need to do the entry as sudo, vs opening a virtual console as root. My root password is non-trivial.

Can we sort the above "data" text, based on "number of characters" instead of "character order"?

When generating WEP Keys the available bits are: 64/128/152/256; however, you need 5/13/16/29 character respectfully for each key if you generate the key manually.Can this formula be applied to passwords and the length of the password? For example: if my password had 29 characters, could I say that my password is 256-bits?
