• Wrong notification on GNOME Shell?

  - by audrianore

  I just installed GNOME Shell on my 12.04 a couple hours ago. The notifications are just cool, and I installed shell extensions, and it works smoothly in 1 hour. Then I restarted my computer for some reason, start back in to GNOME. And I was surprised with the default notification showed up. It replaced the GNOME notifications! I tried to: Reinstall gnome-shell. (autoremove and install) Reset desktop configuration. But it didn't work at all. Is there anything I can do to fix it? Plus: I got a double notification (osd + gnome notification showed up) when someone chatted me.

• Moving ordered elements and adding arbitrary text in Deliverance

  - by Jon Hadley

  Using the following XPath derived rule, I am able to select a list of events from a Plone site (similar to Plone Community events) and display them in my Deliverance themed site: <replace content="//*[@id='parent-fieldname-title' or @class='explain' or @id='parent-fieldname-location' or @id='parent-fieldname-text']" theme="#center-content-to-replace-one" /> However, two separate, but related, problems now rear their heads. I can't work out how to: Re-order elements within the replaced theme, such as moving images originally held within #parent-fieldname-text to before #parent-fieldname-title Put arbitrary text before elements. Such as 'Page Title:' before #parent-fieldname-title I could do both if I was just dealing with one record, as place holders(1) or text before place holders(2) could be specified in the template - but I can't see a away for that template behaviour to repeat across multiple items in one page. (if that is indeed the solution) Is this a job for pyQuery?

• How to manage multiple versions of the same record

  - by Darvis Lombardo

  I am doing short-term contract work for a company that is trying to implement a check-in/check-out type of workflow for their database records. Here's how it should work... 1) A user creates a new entity within the application. There are about 20 related tables that will be populated in addition to the main entity table. 2) Once the entity is created the user will mark it as the master. 3) Another user can make changes to the master only by "checking out" the entity. Multiple users can checkout the entity at the same time. 4) Once the user has made all the necessary changes to the entity, they put it in a "needs approval" status. 5) After an authorized user reviews the entity, they can promote it to master which will put the original record in a tombstoned status. The way they are currently accomplishing the "check out" is by duplicating the entity records in all the tables. The primary keys include EntityID + EntityDate, so they duplicate the entity records in all related tables with the same EntityID and an updated EntityDate and give it a status of "checked out". When the record is put into the next state (needs approval), the duplication occurs again. Eventually it will be promoted to master at which time the final record is marked as master and the original master is marked as dead. This design seems hideous to me, but I understand why they've done it. When someone looks up an entity from within the application, they need to see all current versions of that entity. This was a very straightforward way for making that happen. But the fact that they are representing the same entity multiple times within the same table(s) doesn't sit well with me, nor does the fact that they are duplicating EVERY piece of data rather than only storing deltas. I would be interested in hearing your reaction to the design, whether positive or negative. I would also be grateful for any resoures you can point me to that might be useful for seeing how someone else has implemented such a mechanism. Thanks! Darvis

• What's happened to my directory on GitHub?

  - by Greg K

  I added a new subdir within my git respository: git add feeds Then commited this and pushed it up to GitHub but it seems as though I've commited a symlink / shortcut but not the actual directory and files within. See here: http://github.com/G4EGK/RSS-Reader Any idea what 'feeds' is? I'd like to remove that and correctly add my files. I tried the following but git status said nothing had changed: git rm feeds git add feeds/\*.php To remove feeds do I run the following? git filter-branch --tree-filter 'rm -f feeds' HEAD

• Control an embedded flash movie's playback in HTML/php

  - by lostInTransit

  Hi I am using an embedded flash movie in my web page. I would like to show some alerts on the page when the movie has played for x seconds, pause the movie while the user views and dismisses the alert and start playing the movie again after that (or the user can press the play button, not important) The important parts being - the app being able to find out if x secs worth of movie has played, pausing the movie then and showing an alert. Is this possible using a php/javascript code within the web page? Or will I have to do this within the flash movie itself? Thanks.

• Unity Search Not Working

  - by greggory.hz

  When I attempt a search after hitting Super, the spinner spins, but no results come up once the spinning stops. I'm not sure what changed that caused this. I had a newer kernel installed, but I have since reverted back to the default kernel. I also followed this guide: http://www.webupd8.org/2011/04/how-to-reset-unity-launcher-icons-or.html Alt+F2 does not work. The packages unity-place-applications and unity-place-files are installed. But search still doesn't function correctly.

• Can't set 1280x1024 with Nvidia Geforce 8400 GS

  - by torbengb

  I've just installed 10.04 LTS using the Windows installer. The system hangs during boot; the splash screen is frozen and it accepts neither Ctrl+Alt+F2 nor Ctrl+Alt+Del, only a hard reset. (I'm a linux noob.) When I edit the default Grub boot option to omit quiet splash, it gets to the point saying * setting sensors limit [OK] _ and there it stays. I can only get to the desktop using the Grub recovery boot option, of course with a lower resolution (800x600) but everything else seems to work fine. As I said, this is a new install. The only thing I've done is to use the Update Manager to get everything up to date, and activate the newest Nvidia driver using the "Hardware drivers" window. I had a similar problem when I installed 9.04 a year ago, and at that time posted this question with an answer that worked - this doesn't work with 10.04. Running nvidia-xconfig to create a new xorg.conf didn't fix it either (while in Recovery boot).

• Arabic disappeared after 12.04 upgrade!

  - by Aboubakr

  Well, I was amongst the 12.04 Beta upgraders, and since then I've lost the ability to write in Arabic, and I've been using Ubuntu since 2008 as an only OS without any issues, and been upgrading since then as well, except on this machine, which received one upgrade from 11.10 to 12.04 and it got messed up. I've added Arabic like usual, but it doesn't change with the keyboard's short-cut, and when I do it manually with the Mouse, then it just doesn't work, and it keeps writing in English instead. I've tried to install some iBus things, and added Arabic-kbd (m17n) but it still remains messy, let alone not having the same layout, and all I want is to get to NORMAL. So, please, is there any way to reset or initialize these keyboard related settings, so I can get back to normal and stop using the Mac just to type in Arabic, or so often using XP over Vbox? And please, no Re-install option! I just can't backup all my work right now, and there are a lot of tasks waiting for me to get them done. Thanks for any kind of support :)

• New Office 2010 theme added for creating current UIs

  - by Webgui

  Visual WebGui offers its developers a set of out-of-the-box themes which they can easily apply to their applications. This allows developers to focus on the development and business logic rather than dealing with UI design missions. However, design tools and customization freedom are available for those who need to customize current themes or create their own custom theme. As part of the constant updates and enhancements to Visual WebGui and its developer CompanionKit a new available theme was added last week. The new theme applies the latest Microsoft UI - Office 2010 to Visual WebGui and allows developers and/or end users (of 6.4.0 and above) to switch their Web applications UI to the successful design of Office 2010. After the latest update the new theme is integrated into the Visual WebGui Developers CompanionKit which now matches Visual WebGui 6.4.0 Release version's infrastructure. The update also includes several enhancements to existing controls and features and the addition of some new ones. Go to the CompanionKit

• How to Power Cycle Your Gadgets To Fix Freezes and Other Problems

  - by Chris Hoffman

  Have you ever had a smartphone, laptop, tablet, or any other electronic gadget become unresponsive? The surefire way to recover from the freeze – assuming it’s not a hardware problem – is by power-cycling the gadget. Most geeks know that pulling and reinserting a device’s battery will force it to recover from a freeze and boot right back up, but what if the device doesn’t have a removable battery?

• /usr/share/apport/apport-gpu-error-intel.py Error

  - by gopherballs

  I was on Ubuntu 12.10 and ran the system updates and after the re-install, the system became unstable and kept prompting me with the message "System Issue" and this as the error per Ubuntu "/usr/share/apport/apport-gpu-error-intel.py". After I tried re-starting, the issue is still appearing and the system ultimately freezes (requiring a hard reset). I tried a clean install of 12.10 and the system works fine until the newest updates are applied...it then returns to the same messages. I then tried a clean install of 12.04 LTS and just like 12.10 it works until the latest updates are applied. On 12.04, I tried to use the previous kernel - going from 3.5.0-26 to 3.5.0-23 and the issue is still there. Currently, I'm sitting on 12.04 LTS clean install without doing the updates and the system is working. Does anyone have an idea how to fix this? Thanks.

• Redirecting user from an old web to another in Sharepoint

  - by BeraCim

  Hi all: I want to add the ability to redirect users when they visit certain old sites. The URL of the old sites are unknown, but the server name is the same, e.g. Old site url: http://sharepoint/mySite/default.aspx New site url: http://sharepoint/myNewSite/... There are a lot of other pages within mySite, most of which must be redirected to the new site, but there are exceptions (e.g. user can still view the documents within the site). I thought I have to do this programmatically by somehow capturing the http request and read the url myself. Being no sharepoint guru, I had a quick google, and found that writing a web part is prehaps the best alternative for my situation. But I'm just wondering, given my situation and needs, is writing a web part, or something programmatically, really the ideal solution? Or is there a faster and quicker way to achieve what I want using Sharepoint? Thanks.

• How do I make my volume indicator operate in decibels instead of percentage?

  - by ethana2

  When I want to adjust the volume of anything I'm doing, I find that using the volume controls built into Ubuntu is little but confusion. When the volume is around 100%, dropping it several increments has almost no effect on apparent volume, but when it's around 0%, the effect of one click of my mouse wheel is probably a good 3 decibels. I have observed this behavior on tens of different UC's, since I convert about one Ubuntu user a month (NE team contact). This has proven so frustrating to me that I tend to use the volume knob on my guitar amp ( mono audio :| ) instead of the volume indicator. What can I do to make my volume indicator behave properly until this is fixed? I want each volume increment to be one half or one third decibel. Is there a different piece of software I should use for system volume configuration perhaps?

• Disc Drives: An Endangered Species

  - by Jason Fitzpatrick

  More and more computers are shipping sans-disc drive leading many industry watchers to proclaim the optical disc an endangered species on its way out. Do you still use your drive or are you letting the disc go? CNN Tech reports on the trend: Apple’s new iMac, its flagship desktop computer, was released Friday. For the first time, it has no disc drive. This marks a trend that has already begun on some laptops, like Apple’s MacBook Airs, and of course with mobile devices like smartphones and tablets. “Over time, an optical disc will be as much of an historical curiosity as a floppy disk,” said Michael Gartenberg, a tech-industry analyst with research firm Gartner Inc. According to Apple, where sleeker, thinner designs are always en vogue, dumping the disc drive was a no-brainer.

• Use hotplug and turn on/off PCI device for replacing NIC

• Prevent shutdown when rsnapshot is running

  - by highsciguy

  Since shutdowns during rsnapshot operation will lead to inconsistent/partial backups, I wonder how to delay the system shutdown while rsnapshot is active. The task is complicated by the fact that I need a solution which is compatible with non-expert users. I.e. I need to tell reliably to the user that he needs to wait until the process is finished and not to do a hard reset. Once this is the case shutdown should continue. A possible solution could be to replace the action of the window managers (mostly KDE) shutdown/restart/hibernate buttons by a script which first checks if rsync is active and shows a message if this is the case. But I do not know if this is possible in KDE.

• Unity Launcher and Menu Bar disappeared in 14.04

  - by Justice2497

  The menu bar and Unity launcher have disappeared in Ubuntu 14.04. Also cannot access the terminal via ctrl + alt + t. I have tried every solution for this issue that I can find, from re-installing untiy and compiz to resetting Unity and everything. I've gone into the compiz manager and reactived Unity. Nothing has worked. When trying to reset Unity, or do anything with it really, I get this message (process:6332): dconf-WARNING **: failed to commit changes to dconf: Could not connect: Connection refused EDIT: Installed 14.04 a day ago. The issue happened after a reboot. After installing virtual Box

• List of IP addresses/hostnames from local network in Python

  - by joshhunt

  How can I get a list of the IP addresses or host names from a local network easily in Python? It would be best if it was multi-platform, but it needs to work on Mac OS X first, then others follow. Edit: By local I mean all active addresses within a local network, such as 192.168.xxx.xxx. So, if the IP address of my computer (within the local network) is 192.168.1.1, and I have three other connected computers, I would want it to return the IP addresses 192.168.1.2, 192.168.1.3, 192.168.1.4, and possibly their hostnames.

• Most Efficient Alternative Method of Storing Settings for iPhone Apps

  - by JPK

  I am not using the Settings bundle to store the settings for my app, as I prefer to allow the user to access the settings within the app (they may be changed fairly often). I do realize that there is the option to do both, but for now, I am trying to find the most optimal place to store the settings within the app. I have a good number of settings (from what I have read, probably too many for NSUserDefaults), and the two main options I am considering are: 1) storing the settings in a dictionary in the plist, loading the settings into a NSDictionary property in the app delegate and accessing them via the sharedDelegate 2) storing the settings in a Core Data entity (1 row on Settings entity), loading the settings into a Settings object in the app delegate and accessing them via the sharedDelegate Of these two, which would be the optimal method, performance wise?

• More strict query yields more results?

  - by Mark

  I've got a query that looks like this affiliates = User.objects.annotate(referral_count=Count('referrals')).filter(referral_count__gt=0) But when I restrict it more by adding referrals__user__date_joined__gt=start_date to the filter, I get even higher referral counts. I'm trying to count the number of people a user has referred within a time period. The relevant model looks like this: class Profile(models.Model): user = models.ForeignKey(User, unique=True, related_name='profile') referred_by = models.ForeignKey(User, null=True, blank=True, related_name='referrals') In contrast, when I try it like this: affiliates = User.objects \ .exclude(referrals__user__date_joined__lte=sd, referrals__user__date_joined__gt=ed) \ .annotate(referral_count=Count('referrals')) \ .filter(referral_count__gt=0) The exclude statement seems to do nothing... the counts don't change (should be 0 if no referred users have joined within that time period, but it isn't).

• MAMP Pro Installed On Mavericks 10.9

  - by cnps

  I have MAMP Pro Installed. I'm well aware with the advanced features of MAMP Pro I can change to different types of Hosts, but I wanted to know why my previous method would not work within mavericks. This was my usual working method in 10.8, but now with 10.9 it's a headache. The previous method would: Write a custom address with the host address: "#Virtual Hosts" 127.0.0.1 nameofsite.local go to /Applications/MAMP/conf/apache and open the httpd.conf file, scroll to the bottom and then add NameVirtualHost * DocumentRoot "/Applications/MAMP/htdocs" ServerName localhost DocumentRoot "/Users/Klimt/Sites/siteoffolder" ServerName clientA.local make sure the ports is set to 80, 443, 3306. reset MAMP PRO and then usually type in the url address and it's gold from there. any help?

• Python namespace in between builtins and global?

  - by Paul

  Hello, As I understand it python has the following outermost namespaces: Builtin - This namespace is global across the entire interpreter and all scripts running within an interpreter instance. Globals - This namespace is global across a module, ie across a single file. I am looking for a namespace in between these two, where I can share a few variables declared within the main script to modules called by it. For example, script.py: import Log from Log import foo from foo log = Log() foo() foo.py: def foo(): log.Log('test') # I want this to refer to the callers log object I want to be able to call script.py multiple times and in each case, expose the module level log object to the foo method. Any ideas if this is possible? It won't be too painful to pass down the log object, but I am working with a large chunk of code that has been ported from Javascript. I also understand that this places constraints on the caller of foo to expose its log object. Thanks, Paul
