Problem viewing available pacman updates with conky

Hi. I'm having problems with showing available package updates in my conky layout. I tried to follow instructions from archwiki https://wiki.archlinux.org/index.php/Co … nformation but none of the scripts seemed to work correctly, but instead they always show 'System is up to date' even though 'pacman -Qu' shows multiple packages available for update.
Following https://bbs.archlinux.org/viewtopic.php?id=37284 my conky has (I changed 'python' -> 'python2' so script compiles):
${texeci 10800 python2 /home/laite/.config/awesome/conky/packages_python.py}
Actually, I just noticed that last post in that topic seems to have the same problem than me (https://bbs.archlinux.org/viewtopic.php … 74#p863474)
Does anybody know how to get this working or maybe some other way to show updates in conky? I already tried all the scripts from wiki with no luck.

Thanks
If somebody wants to know, here is my (very slightly) edited bash script:
#!/bin/bash
_pacPackages=$(pacman -Qu | wc -l)
if [ $_pacPackages -eq 0 ];
then
echo "\${color #ffffff}Your system is up to date.";
elif [ $_pacPackages -eq 1 ];
then
echo "\${color #ffaa00}1 new package";
else
echo "\${color #ffaa00}$_pacPackages new packages";
fi
exit 0
and conky:
${execpi 7200 sh /home/laite/.config/awesome/conky/package.sh}
Also, I have script updating packages in cron/hourly:
#!/bin/sh
pacman -Sy

Problem view TIFF multipage images with ECL Viewer 5.1.3

Dear All,
using the SAPGUI 710 and CV04N, I cannot view the same TIFF multipage image twice in ECL Viewer, the second time, the first time every thing is ok, but the second time the SAPGUI display the error : "File C:Docume1dupondLOCALS1TempZEP_0457895 cannot be created"
To view again the TIFF mulitpage image, I need to kill the sapLogon.exe process and relaunch it again.
It seams the TIFF image file is locked by the the saplogon.exe process the first time and on the second time, SAP cannot rewrite the temporay TIFF image file.
Notes:
- I use CV04N or CV03N to view the documents.
- This problem doesn't happends with non multipage TIFF image.
- Tested on more than 20 computers.
- Computers are with Windows XP SP2 + SAP GUI 7.10 Compilation 2 + SP9 + SP12 + - ECL Viewer 5.1.3 (integrated with Comp 2)
How can I fix this problem ?
Thank you for your help
I think this is not the correct forum to post this king of problem, i create the same post on

Can you upgrade the ECL viewer to version 6.0 and check whether the same problem still exists? you can download from service.sap.com

Conky - Display available pacman updates

This is a python script I found and modified to display package update info with conky.
The original was written by Majkhii and Sabooky which I found here via the wiki entry for conky:
https://bbs.archlinux.org/viewtopic.php?id=37284
This one is much simpler than it's predecessor. It will simply display a list of package names and their sizes. I couldn't figure how to keep the rating system from the original which allowed for highlighting "important" packages. Anyway here it is. I'm pretty new to programming so if something doesn't seem to make sense, it's probably because it doesn't.
#!/usr/bin/env python2
~/.conky/notify.py
-Description: Python script for displaying archlinux updates.
-Usage: create shell script with the contents:
#!/bin/bash
# ~/pacsync.sh
# This syncs pacman and creates a file to store
# info for each package. This is so the python
# portion doesn't constantly use your network
# connection every 20 seconds to get package info
# when it refreshes itself. Better to have the
# shell script update once every several minutes
# and have python use that info instead. Don't
# forget to make executeable with chmod +x
destfile=~/.pacsync.info
sudo pacman -Sy
if [ -f $destfile ]
then
rm $destfile
fi
list=`pacman -Qu | cut -d ' ' -f 1`
for x in $list
do
echo $x >> $destfile
echo `pacman -Si $x | egrep -w 'Version|Download'` >> $destfile
done
-Create the following crontab with 'crontab -e'
to have pacsync.sh run every 30 minutes:
*/30 * * * * /path/to/shellscript
-Conky: Add the line '${texeci 20 python path/to/this/file.py}'
where 20 is the update interval in seconds
-Also, if part of the output is not showing in conky
increase text_buffer_size value in conky config
I use 'text_buffer_size 1024'

Installation:
As the comments state, create a shell script with the following:
#!/bin/bash
# ~/pacsync.sh
# This syncs pacman and creates a file to store
# info for each package. This is so the python
# portion doesn't constantly use your network
# connection every 20 seconds to get package info

# and have python use that info instead. Don't
# forget to make executeable with chmod +x
destfile=~/.pacsync.info
sudo pacman -Sy
if [ -f $destfile ]
then
rm $destfile
fi
list=`pacman -Qu | cut -d ' ' -f 1`
for x in $list
do
echo $x >> $destfile
echo `pacman -Si $x | egrep -w 'Version|Download'` >> $destfile
done
Make it executable:
chmod +x /path/to/shellscript
Then create the following crontab with 'crontab -e':
*/30 * * * * /path/to/shellscript
This will cause pacman to check for updates every 30 minutes.
Finally, place this line in your conky config:
${texeci 20 python path/to/notify.py}
Where 20 is the update interval in seconds.
Note: If conky doesn't display all of the output correctly, increase the text_buffer_size in your conky config. I use:
text_buffer_size 1024
Make sure to check out the basic settings like output width, format, or one line summary. All credit goes to Majkhii and Sabooky as they did all the heavy lifting and I merely butchered their work to suit my system.
That's it. I've been running this for 3 days with no issues so far. Questions/comments/concerns welcome. I'll try to work on this if need be, but I may have conflicts with school as I'm currently a student.
*EDIT* Fixed screenshots

1. No need for 'cut', we already have a pacman switch for that:
$ pacman -Qu | cut -d ' ' -f 1
wine
wine_gecko
$ pacman -Quq
wine
wine_gecko
2. You can use 'expac' to get version, size etc.
3. Doing 'pacman -Sy' is not necessarily a good idea. http://www.andreascarpino.it/blog/posts … s-part-ii/

Problem viewing videos I recorded with the phone

When trying to view videos I recorded with the phone, It gives me a message saying it is impossible to view this multimedia file format!
It has been recorded with the phone and it can't watch it on the phone!? It doesn't recognize its own recording format
Help please

If the format is in 3GP you can view it with a player called VLC (http://www.videolan.org/vlc/), or can try a video conversion program to convert it into a format your computer can read. Once such program can be found here http://www.avs4you.com/AVS-Video-Converter.aspx

Problems Viewing .pdf Template Created with Adobe

I created a .pdf template using Adobe LiveCycle Designer. After I upload this template, I can not view the report. Can I only create templates using the BI Publisher plugin for MS Word?

That is hardly a solution, the whole purpose of upgrading to Adobe Reader X is to avoid potential threats. There is obviously a problem with Adobe Reader X and veiwing certain documents that needs to be addressed and the way to address it should not reside with "Use Adobe 9 and Adobe 10 and pick whatever version works for your document"

Problems after flash player update with firefox

I have problems with video streaming on firefox after the flash player updated to 11.7. The video plays but the audio suddenly stops while the video continues to play but will also stop after a few seconds. Does anyone know what may cause this problem?

Hello,
Flash Player installs to the Windows directory that standard user accounts do not have access to, therefore, Admin access is required for installation.

[solved] Perl script for pacman updates in Conky

Hi
I've been using this script in Perl Conky to check on updates. It works well.
It's not mine - I got it here;
http://bbs.archlinux.org/viewtopic.php?id=57291
#!/usr/bin/perl
## script by Xyne
## http://bbs.archlinux.org/viewtopic.php?id=57291
use strict;
use warnings;
my $n = (`pacman -Qu | wc -l`);
chomp ($n);
if ($n == 0)
print "System up to date"
elsif($n == 1)
print "1 new package"
else
print "$n new packages (inc. IgnorePkg) "
I have some packages listed in IgnorePkg in pacman.conf - is there a way to exclude them from the packages counted in $n?
I thought something like this would help but I don't see how to take only part of a line from IgnorePkg
http://www.perlfect.com/articles/perlfile.shtml
Thanks for any help
EDIT I added a --ignore clause to the pacman query. Seems to have worked. Sorry to waste your time.

Edit: Finally figured it out. My router assigns IP adresses dynamically on each reboot. When my IP adress changed from 192.169.1.2 to 192.168.1.3 the hellaconk script got all confused. Ahh...

Problems viewing HDV .mov file with Intel MacBook

I have a HD QuickTime file exported from FCP HD on G5 PowerPC. I cannot play this file on my intel macbook, I get a white screen.
Any idea why?
Thanks
Brian

You'll need to copy the Apple HDV Codec to your MacBook. Since it won't be Intel native (unless you get FCP 5.1) you'll have to force QuickTime Player to run in Rosetta; it should be a setting in the Get Info window for QT Player. You should then be able to view the video (though I haven't tested this myself).
Hope this helps.

Problem viewing movies in netflix with 32 version

when i got to view a movie, firefox wants to start in 32 bit mode.. i say okay but apparently it no longer reloads in 32 bit mode because it keeps asking me to restart in 32 bit mode. help!!

You can use these steps to start Firefox in 32 bit mode:
#Close Firefox

#Right click or control-click the Firefox.app icon
#Select "Get Info"
#Select or Deselect "Open in 32-bit mode"
#Close the "Firefox Info" window # Restart Firefox

Pacman update failing (openjdk7 and rhino?)

hi,
I am getting the following error when doing pacman -Syu:
:: Starting full system upgrade...
resolving dependencies...
warning: dependency cycle detected:
warning: rhino will be installed before its jre7-openjdk-headless dependency
looking for inter-conflicts...
error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: openjdk6 and jre7-openjdk-headless are in conflict
I had openjdk7 (+ headless) and rhino installed, but I uninstalled them all and installed openjdk6 (cos 7 is incompatible with a lot of programs I use).
Does anyone have an idea how to get rid of this error? I don't even remember what rhino is or what I needed it for.
thanks

eclipse, maven3 for sure
and maybe minecraft.
first time I installed eclipse and maven3 I installed them with openjdk7. after removing opnejdk7 I uninstalled all of them and reinstalled them (with openjdk6). I have no problems besides the pacman update.

Problems viewing videos and trailers after the lastest Flash Player update

I have Windows 7 - 64 bit, I use Firefox 11 (latest version) and Chrome (latest version); however, since I have installed the latest Flash Player update, I cannot view any trailers or some videos. Youtube works fine, but other sites dont (I just get a green screen). Please can someone assist me? I have tried the "Help" section for Flash Player and it hasn't been too helpful.
Thanks in advance!
Ok, I found the problem, my hardware acceleration was set to enabled, once I disabled it, I had no problems viewing any of my sights that used Flash.

You might want to update your driver, particularly if you have an NVidia GPU. Here's a post where we describe this process and ask for additional details so we can resolve this for others.

Keynote document saved in icloud not updating with data from Numbers? is icloud the problem

keynote document saved in icloud not updating with data from Numbers? is icloud the problem.
If both files are held locally on the computer it looks like there is no problem however if you try and do it though icloud (ie your docs are saved on icloud) you dont get the "source" oprion besides the graph etc. Is this a but or a broken function due to the new implementation of icloud.

Hi sebnor31,
This is Visual C# forum, but your question seems not related to Visual C# language itself. It most likely related to the bluetooth message transaction protocal or with the device itself.
I'll move your question to [where is this forum for...] forum where the morderator may direct you to the correct forum.
