General :: Where Are The Paste Buffers Managed

Jun 19, 2011

On standard Linux setups you have two general paste buffers, the main copy(^C)/paste(^V) one and the select-text/middle-click one. For both of these buffers:

At what level in the environment are these buffers stored/managed; the kernel, the X server, KDE/Gnome, or some other service somewhere? Can they be programmatically accessed somehow using some standard library?

General :: Synchronous Sync Of Buffers In File System

Jan 11, 2010

As per the documentation of sync [URL] , it schedules the writes but does not necessarily complete the write upon return.

Is there any other way to make sure we sync and it returns after it has written all the buffers to disk?

General :: Emacs - Search And Replace Regex In Multiple Buffers?

Apr 7, 2009

I'm fairly comfortable with emacs but I can't seem to find how to do this. I deal with a lot of text files and find myself performing a lot of regular expression replacements to correct the formatting of the text -- or to extract certain tidbits of data from large ugly-looking files.

I know how to perform a regular expression replacement in one buffer at a time. But how do you perform a regular expression search and replace across all open buffers? I have found a method to perform a regex search and replace across a directory by marking files but I need to do it in the open buffers.

Is there any tool or sort of shell script we set via crontab every minute to check that?

Ubuntu :: Twitter Status / Update Pidgin Status In Lucid

Jul 5, 2010

I have just upgraded to Lucid on Ubuntu. I am a long time Pidgin user. I tried using Empathy with Gwibber, but I can't get Gwibber to update my IM status(es) in Empathy, so I want to go back to using Pidgin. (Additionally, I can't get Skype to work with Empathy.)I installed pidgin-microblog and pidgin-mbpurple, and they allow me to view my Twitter feed in Pidgin and update my Twitter status in Pidgin. However, in Karmic, I was also able to specify certain "status availabilities" (one named "Twitter-Available" and one named "Twitter-Away", for instance) to have the IM status message for these statuses become populated with my Twitter feed. This capability seems missing in pidgin-mbpurple in Lucid (and it seems to be the only thing missing from Karmic).

Is there a way to have pidgin-mbpurple update certain "status availabilities" in Lucid (and I'm just missing something) or is this no longer possible?Equivalently, is it possible to have Gwibber update my status message in Empathy? (I just want to be able to update my status once on one of my three computers - and have it propagate to all my other accounts (IM and social networking) and computers).

OpenSUSE :: 11.2 - Macros Opening Separate Buffers / Windows

Feb 8, 2010

I switched from 11.1 to 11.2 last month. I'm now having a smoother experience with openSUSE, with some exceptions.

One is Emacs.
A rather annoying "feature" that has appeared is the following: When editing a LaTeX file, compiling it (C-c C-c, using AucTeX macros) makes the Emacs window become shorter by one line. The same happens if I switch to some other buffer. It does not happen if I switch back to the LaTeX buffer. So, after just a few editing/compiling/checking errors sequences I find the original window half of its initial size...

A similar problem occurs when editing IDLWAVE scripts (it's a proprietary scientific data analysis language widely used in my field, but still has its Emacs macros), but only if I open an interactive IDL-shell to run the script.

So, I imagine it's not a problem related to AucTeX, although it might be related to the macros opening separate buffers/windows (e.g.: error messages) associated with the current buffer. Also, the problem does not go away if I remove my own .emacs customization files. Checking the Emacs bug lists, it seems that there are some bugs related to window resizing, although I have not been able to find exactly the same problem I am having. But, before reporting this one, I'd like to hear from fellow Emacs/openSUSE users. Just in case I'm messing things up somehow.

Currently using: Emacs v 23.1.1
Some more info: Dell Precision M65 portable workstation, NVIDIA Quadro FX1500 using the binary NVIDIA driver). Using OpenSuse 11.2 + KDE 4.3.1

Ubuntu :: Is Alt+SysRq+o Shutdown 'clean' With Regard To Disk Buffers?

May 3, 2010

I've been having a bad problem with X freezing up (but not the whole system), and I hate continually performing unclean shutdowns with the power button.Will an Alt+SysRq+o shut down the system in a way that doesn't cause the loss of disk buffers? Obviously, whatever hasn't been saved to the buffer will be lost, but my concern extends to the buffers themselves.ext4 and autofsck make this less of an issue, but I hate the thought of unnecessary silent corruption until the freezing stops.

General :: Network Stop Working After Heavy Load Of Packets Received

My LAN has 2 PCs installed, Ubuntu 10.04 and Windows XP. I run the server on Ubuntu, and client on Windows XP. Because I am doing stress test, so the client will keep sending tons of packets to server.

The strange thing is: After few seconds, the client program crash because of insufficient network buffer, the server is still ok. But after that I cant connect Ubuntu PC anymore until I restart it. And I check the router, the led for the Ubuntu PC is always ON (not blinking), look like it is jam already.

Ubuntu :: Remove Gwibber Status Indicator / Gwibber Status In The Panel While Keeping The Shutdown Button?

Mar 16, 2011

After a fresh installation of Ubuntu 10.10 I uninstalled empathy (im using skype). The empathy menu in the evolution indicator was gone after that.I also uninstalled gwibber. But the gwibber status indicator remains within the about-me panel... Uninstalling the gwibber package also removes the me-menu which I want to keep actually. Especially the shutdown/restart... part of it. See attachment.I know there is a shutdown panel-app...but its butt-ugly and it doesnt allow to logon/off.

In another thread I read that the gwibber status shouldnt be there if no account for it is configured... which it is not... I do use ubuntu-one though which is in the same menu... I saw that this issue was addressed at some bug report before, but not fixed yet...

Does anybody know a good workaround to get rid of the gwibber status in the panel while keeping the about me and the shutdown button?

Programming :: Displaying The Contents Of Buffers In A Protected And Non-protected Critical Section?

Nov 19, 2010

I have this project for my operating systems class and I have put together the basic flow chart to aid me in writing the program. I know how to use pipes as a buffer to hold info. I know how to create a binary semaphore. But what I dont know is this:

How to "use a delay adjustment parameter K in the critical section to adjust the speed of the display process to show that without semaphore protection the displayed contents of the buffer are randomly interleaved."

First off, I am definitely not asking anyone to give me the solution. But I do need some guidance. So I figure there will be an if statement with two options:

1. If true, use semaphore protection to enter/exit critical section

2. If false, no semaphore protection -- this is where the contents of the buffer should be interleaved.

Now does that mean that as each child process enters the non-protected critical section, it should "sleep" for a randomized time? I mean, will this allow my output to be interleaved?

So lets say my command line looks like this:

what happens to the 100? Is it randomized using rand and srand and passed as a parameter to sleep() inside the critcal section?
