Programming :: Numdisplay Won't Display Anything In Debian
Apr 20, 2009
There is no package for numdisplay python module (at least I haven't found one), so I've downloaded it from it's home page and successfully installed. I can import it, but I cannot open an image with it. For example I have this simple code (doesn't matter whether is it a standalone file or whether I run it from ipython):
Code:
It fails with the following error (taken from ipython as it's more specific than if I run the file, but it basically says the same):
Code:

I'm testing HTML5 for the first time, using Firefox (beta) 4.0b8 and SeaMonkey (beta) 2.1b1, and its ignoring some CSS. Specifically, I have problems with the <details> tag. (It is nested in a paragraph...I am using it to provide an in-paragraph definition in hopes it can be toggled.)
Firefox only partly supports <details>. It's not supposed to show anything except the content of <summary>, unless you click on <summary>'s content. Instead, it puts a line break before the content of <details>, splitting the paragraph in two peices (which looks silly), without the "closed/open" functionality.
So I tried using "display:inline" in my CSS, but that gets ignored. Just for fun, I also tried "display:hidden" (also ignored) and "display:none" (obeyed).
SeaMonkey doesn't doesn't do anything special with the content of <display>...but it also ignores the same CSS as Firefox.
The only thing I can do to support semantic design is apply "font-style:italic" to all <details> elements.
Granted, you might ask, "why bother using <details> at all. then?" Well, I would like to have <details> for the browsers that support it, with the "font-style:italic" to degrade the page nicely for those that don't (such as for SeaMonkey).
Does anyone know why "display:inline" and "display:hidden" get ignored?

I am struggling a little on how to best approach this problem. I have wrote a server program that runs via xinetd, that obviously spits out data at the client end. Fairly straightforward stuff?There is a point in my server code where I need to display an image/gui i.e something that runs on X11 that prompts a user to perform a task on the display connected at the the server side.So far I have written a test program that displays some text at the client end and then launches the browser at the server end. I have also set the following export. Code: export DISPLAY=:0 and then goes on to launch my web browser. Works great when ran locally on the server and when I remotely telnet in to the server and run the code.
However when I try to run the same piece of code as a xinetd service the export seems to have zero affect and the client terminal window displays errors associated with there not being a X11 server running.The code launches fine when I create a socket to serverip:6556 it just the ability to display gui programs to another display that does not seem to be working.

I am having trouble writing an Xlib application that displays a window. The most frustrating thing is that I've written applications like this before, and never had any problems. For some reason I cannot get this program to work properly. I'm running KDE and when I launch the program, a "button" for the application will appear on the application panel, however, no window will display. It is possible to right click on the panel button and select the Close item which will successfully close the window.
The following is source code that when built will exhibit the behaviour described above code...

I have hundreds of thumbnail images and I need to display on the client side one name only for each when the visitor passes the mouse over them. The only way I know (using frames in this case) is to use a script similar to the following:
<a href="" target="" onMouseOver='top.nav3.location="not/notecome.htm"' onMouseOut='top.nav3.location="nav.htm"'>
But this involves creating a full and w3c correct HTML document which looks like an over-kill of the problem.
Is there a simpler way to solve the problem? If not, is it acceptable to use a truncated HTML document comprising only the necessary tags to make it work on the test machine (<html><body><.....onMouseOver.....></body><?html>
Or a way to display the content of the "alt" tag (I can put that name there)?
In the worst case, I could use the javascript "Alert" but it does not fit esthetically and it needs one mouse click from the visitor. Is it possible to make one's own "Alert" picture and how?

I have a file, and I have to display all the lines from the beginning of the file till a matching string is found.
I know grep with "-a", "-b" as option does exist, but it needs the number of lines to be printed in advance. eg grep -b 10 "search_string" file so it will print 10 lines before a match is found.

I am trying to write a small gtk+-2 program to display whatever image it is given and I was wondering if anyone out there has done something similar. I am not too familiar with writing programs for gtk and its been a while since I've fiddled with C. I went over the tutorial for gtk and it seams pretty easy to get a window to display, but I do not see anything that refers to loading an image or displaying it in the window. I am wondering if this can be done purely with gtk or will I need to use some type of image library like imlib2?

Usually the menu bar, and menus, are displayed within the applications main window. With a small screen this obviously wastes space so my idea is to reserve a location, small square space probably on a corner, on the screen that when clicked it will pop out the current selected applications menu, allow selection, and then disappear again. The application itself would look fullscreen, or if windowed will still not have a menu bar but access available via the "square."
Likewise instead of the usual task bar and "applications/places/system" menus (ala, ubuntu) a second square would be reserved which would pop-out and show the running tasks, followed by the menus, and allow selection, then disappear. Is this possible with GTK+ as it stands, as I'm guessing that by default everything must be contained within an applications main window?
Although having said that, gimp allows the tool windows to be external to the edited document, so perhaps it would be possible to make the menu bar into a toolbox? I guess the difficult problem would be how to make the currently selected applications "tool square" be on top when there could be multiple applications running. The "tool square" and "task/menu square" could be transparent (maybe just an outline) so that although always there they wouldn't hide any underlying windows/programs/etc.
Basically the idea is to get rid of wasted screen, in ubuntu (on gtk/gnome) a minimum of 5 "bars" is wasted screen real-estate:- 1, Running aplications: 2, Ubuntu's main menu bar: 3, Applications status bar: 4, Applications menu bar: 5, Applications description (min/max/close) bar. Take all the above and replace it with two clickable, potentially invisible, squares say where the default "hide all windows" and "deleted trashcan" icons currently reside.

I have a large body of code (2000+ lines at this point) with lots of global variables, and a handful of locals. I would like to know is there a way to print out all global variables in use at a particular moment in time either from the debugger (ideally) or in line?
Basically I have something like this for the menu
1. Do thing 1
2. Do thing 2
3. Do thing 3
4. Do thing 1 and 2
5. Do thing 1 and 3
6. Do thing 1, 2 and 3
The problem is, as you select something from the menu again after you finish an option, the globals are still set and I'd like to clear them. If I had a list of all of them, it be easy to copy and paste and set them before the program ran another entry again. Suggestions? I'm aware of reset [a-z], but all of my vars are uppercase, and I would upset INC, and other upper case built-ins.

I have a problem to use echo to display the content of a variable.
This is what I do:
Code:
#!/bin/bash
USAGE="Usage: name [OPTIONS] [DIRECTORIES]"
echo $USAGE
When I run this little script I get the following output:
Usage: name [OPTIONS] R
So I think that [DI might be some sort of escape sequence. But I do not know how to unescape it. Does anyone have a hint for me?

So I'm teaching myself some scripting to try and create a fairly simple photobooth type affair... I've got gphoto2 playing fairly nicely with my canon, and imagemagick taking that output and rearranging it to a vertical format...
EDIT:
*smacks forehead*
Fairly simple to do what I needed initially: Code: feh -FZ -D 1 --cycle-once $COUNTDOWN & sleep 2 &
feh -FZ -D 20 --cycle-once $SMILE This shows a countdown from 5 to 1 in images and $SMILE is big that says 'smile'
So my question is thus... (fairly basic but I can't get my head round the use of & and sleep in this context) what's the best way to call my gphoto instructions (or a script with them in) mid way through the above code?!
'feh code'
sleep 5
'gphoto code'
this kind of thing seems like the way, but the'sleep 5' and 'gphoto code' doesn't start until feh is finished in this case?

I am running a scan via nmap (nmap -sP) and the out put looks similar to this:
Nmap scan report for x.y.z.com (10.x.x.x)
Nmap scan report for 10.x.x.x
If it can resolve the hostname it does, if not it just spits out the IP. I would like to know the best syntax to use with cut, or awk, so that the only output is either the IP or IP - HOSTNAME.

I am attempting to "export" the progress bar from wget display using sed. Basically, we have an app that starts wget to download a large file and we want to show a progress bar. Our application has a dbus interface to receive the download progress.
So we were think of a command like:
wget [] | sed [] | dbus-send[]
The problem at the moment is, how do you get the matched string out of sed and into dbus-send? I can get the progress string by:
sed -u 's/[0-9]*%/&/'
This populated '&' with the correct percentage, but I cannot seem to get this out of sed.

I am not sure if this is possible. I have IP's stored in a mysql database. When I query the database, it returns the IP. I would like to replace the IP with something else prior to displaying the results. Is it possible even though I have not stored it in the database?
I have the following in a while loop (mysql_fetch_array).
Code:
<td align="left">' . $row[IP] . '</td>
Instead of displaying $row[IP] from the database, I would like it to display something else which I define in the PHP code but based on the IP.
ie. aaa.bbb.ccc.ddd = hostnameABC
