May 11, 2011im building a small wallboard machine, using ubuntu 10.10 as 11.4 refuses to load correctly on any of my spare machines.but, anyway, thats not the issue, ive installed chromium-browser, and added it to the startup applications with
Code:
chromium-browser -kiosk http://wallboard
where http://wallboard is the wallboard info thats being displayed.
that works, BUT the browser is opening BEHIND the top 'menu' bar, and the bottom 'task' bar, which obviously, is not what i want. how do i set it to either hide these 'bars' or open the browser in front of them like it does if i manually run the command from a terminal?
General :: Evolution Task List Reminder (sync With Phone And Online Task List)
May 19, 2011I have my task list in evolution (mainly so it can sync with my phone and online task list) but I always forget to look at the task list. Is there an application or plugin which periodically displays the contents of the tasklist or even better, it briefly displays the most urgent/important tasks when I login? Or anything else which automatically displays the most important tasks. Currently I have to open the task list and look at them (which I usually forget). I do not mean some kind of alarm when the task is due but more a daily reminder of what to do.
View 3 Replies View RelatedServer :: Samba Shares And The Notion Of Group Of Groups
Feb 9, 2011this is really a brainstorming thread seeking advise on how to setup some samba shares within a small office network. For the quick judgers:
-no I'm not an IT expect and I'm not even the IT at the office, I just fill in this gap too.
-I have looked into several samba 'by example' tutorials - none seems to fit my needs or answer some of my Qs.
So I seek advise from your experience: What do I know:
-the functionality of the setgid to have subfolders inherit the group owner of the parent folder
-the fact that I don't want samba in 'share' level in order to register the owners of files
-the functionality of acls that enables inheritance of rwx permissions to subfoldrs of a parent folder.
- the groupmod -o option but that doesn't help apparently.
So this is a 25ppl civil engineer consulting office. The physical groups of ppl working here are: engineers, drafters (those who generate the drawings , i'm not sure if thats the correct term), and secretaries. The job usually is done in the following way, once a project commences a project folder gets generated and everything is done in there. incoming mail arrives there (secretaries put it there), engineers do they calculations on speadsheets, write reports and do draft drawings and, finally, drafters take the draft drawings and finalize them. So pretty much everyone of these 3 groups needs write access to the main project folder.
How do I accomplish that? as which group should I create the project folders? It came to mind the notion of group of groups. Now that the actual owner of the file is not so important anymore (several engineers will need to have write access to the folder) and group becomes important, it would be nice to have the ability to add... groups (instead of users) to groups! so that the permissions to a group are inherited by its children groups... Does such functionality exist of can it be implemented somehow?
How do I go about giving access to everyone and at the same time, NOT giving up on the 'user' secutiry level of samba (and NOT just giving rwx permission to 'others'? Is it possible? or Should I instead forget about individuals and match the 'physical groups' to 'linux users' and 'groups of groups' to 'linux groups'? ( This means I should give on ownership of files by individuals )? Since its a small office some work is mixed - engineers might pickup incoming email, a secretary might do abit of drafting work etcetc.
Ubuntu :: Disable "opening Application X" Notification In Gnome Task Panel?

View 1 Replies View RelatedGeneral :: Run Same Script In Parallel From On Session?
Mar 17, 2010I have a shell script to refresh some databases. Currently I open 5 sessions and to execute the five scripts.
Today, as test, I tried to see if I could run two refreshes simultaneously from one session using the '&':
. /refresh.ksh db1 &
. /refresh.ksh db2
The first one ran and the second one started only after the first one was finished. Could it be that the script refresh.ksh contains many commands and those are not pushed to the background? If so, what's the best approach to getting 5 db's refresh simultanously from on session?
General :: Parallel Processing Slower Than Sequential?
Jul 28, 2011While converting some images using ImageMagick, I noticed a somewhat strange effect. Using xargs was significantly slower than a standard for loop. Since xargs limited to a single process should act like a for loop, I tested that, and found it to be about the same.
Thus, we have this demonstration.
Quad core (AMD Athalon X4, 2.6GHz)
Working entirely on a tempfs (16g ram total; no swap)

General :: How To Identify Current CPU In A Parallel Machine
Sep 1, 2010I do not know much about parallel computing, but I do have access to a few cpus.I am trying to write a program compatible for multiple cpus, but to do it, I need to ensure unique directories. I have figured out that the time of creation, process id, and cpu id form a unique combination I can use to name files (up to the degree of accuracy of the internal timer).Anyway, I am using perl. I know how to find the process id and I know I can get the time pretty easily, but as I said, I do not know much about hardware or parallel computing. All I need is a way to identify each cpu in the system and I am set for half of my program (the other half is significantly more straightforward and is mainly about text parsing.)
So anyway using terminal, perl, etc., I could access this identification? Or could someone at least tell me the name of what I am looking for? I have seen the words "ip" "MAC" "hostid" and a bunch of other "id" things come up in my googling, but I really cannot figure out which is the one relevent to me

Mar 25, 2010I've got a fresh install of ubuntu 9.10 on a fresh disk and everything was going perfectly. I bought a Usb=>parallel cable to connect my old parallel port printer.When I try and print, sometimes it works and sometimes it doesn't. Sometimes the job will go to the print queue and then nothing happens, in this case if I unplug and replug the usb cable a couple of times it usually prints the document. Sometimes the job doesn't show up in the print queue at all and sometimes it prints the document with no problems.
Whenever I use lsusb, I never see the printer in the list of attached usb devices (even when the printer is printing!). Apart from root hubs, the only two devices ever listed with lsusb are my mouse and scanner.

General :: Application Called Impact - Paths In Java Application ?
Apr 14, 2010So, I have this application called Impact, it is an explicit time integration Finite Elements code written in Java...
[url]
I untar the pack, and launch the application calling a script, from within the untarred folder,
Code:
This launches a gui which allows me to setup a case, which needs some setup file, tipically some *.in and a mesh file, tipically some *.msh.
Other mode of executuion consists of calling the setup file as argument to Impact.sh script ( CLI execution mode, for g33k5 )
My problem is : I have packed the whole stuff into a Slackware .tgz, that places it in /usr/local/Impact, and placed a calling script in /usr/local/bin,
Code:
Code:
I decided to hack the ImpactGUI_OGL_linux_amd64.sh script from
Code:
Code:
no avail,
Code:
even after adding /usr/local/Impact/bin to PATH... won't go...
I can run this thing from within its directory... but I do not like messing within the directories of my applications, this is why I sent this to /usr/local, and placed a calling script in /usr/local/bin...

General :: Freeze The Clock For A Specific Task?
Dec 27, 2010For example,
# clock-pause
# touch a
# touch b
# convert -draw `date` text_draw.gif

Or, simply
# freeze-exec sh -c 'touch a; touch b; convert -draw `date` text_draw.gif'
The expected result is the timestamps of a and b, and the text drawn to the image, are exactly the same.
General :: Find What Task Is Running On A Particular Cpu Core?
Sep 17, 2010I am using Kernel 2.6.35.4 on an Intel Core2Duo based system.
1) I have to find on which core a particular task is running on .
OR
2) I have to just log whenever my task is scheduled on any of the cores with the cpu core number & timestamp info. I am ready to modify the kernel to do printk or some logging . I guess there used to be 2 fields called 'processor' and 'last_processor' in task_struct in older kernels which probably had this information .
So what do I do to find out on which core a particular task is running on ?
Or ,
Are there any utilities that are simple-to-use and can display the tasks that are running on each of the cores , including the cpu core info ? top , mpstat etc do not tell you on which cpu core a task is running on .

Sep 21, 20101.) I have several versions of ubuntu installed on my computer. Technically, all but one are incomplete installs which I would like to delete if possible?
2.) I would like to access my files from the Windows partition, but it doesn't show up under "system." Is it for some reason impossible to access Windows files?
3.) My computer's performance has dipped substantially in the last two days. I am trying to figure out why this is, if there is a task manager or the like or a performance diagnosis tool. Also, my computer does not have an anti-virus program, that might also be the cause of the poor system performance.
General :: Display Stretched With No Task Bars Showing
May 21, 2011i have a hp laptop with a cracked screen so i'm using and external monitor. It is an HP vs15c. Now it was working fine.. perfect even.. until i was working on a second virus infect pc in bed with the keyboard connection to this pc next to me. What happened next is a bit embarrassing and also why i have no idea what i did or how to fix it. Well i found the virus in the laptop i was repairing (god i hate vista.) when i wiggled in excitement .. only the keyboard slide under my breast and the next thing i know my screen looks stretched and i have no bars. i can move my mouse beyond the right and the bottom edges of the screen and i can't change anything cause i can't get any option.. or least i don't know how to get them without the bars.. i can't even reboot if i wanted to cause my task bar is GONE. the bottom active bar is there.. off screen where i can see it but if i drag my mouse down far enough it is there to click on things. However the top bar that i need is gone. I am NOT good with terminal.. nor do i know how to open it without the top task bar. Right now i'm cursing a storm and being very angry about being a woman.
