• Window Focus in Scale (Compiz)

  - by Göran

  This is a follow-up question to Expose (OSX Style) Functionality in Unity. I'm having issues with focus. With the help of Compiz Config I have succesfully activated a window picker similar to the one named exposé in Mac OS X (but with more options!). However when I use this function the window I click on/choose is not automatically focused. How can I fix this or is this a bug within Compiz/Scale?

• Sortable & Filterable PrimeFaces DataTable

  - by Geertjan

  <h:form> <p:dataTable value="#{resultManagedBean.customers}" var="customer"> <p:column id="nameHeader" filterBy="#{customer.name}" sortBy="#{customer.name}"> <f:facet name="header"> <h:outputText value="Name" /> </f:facet> <h:outputText value="#{customer.name}" /> </p:column> <p:column id="cityHeader" filterBy="#{customer.city}" sortBy="#{customer.city}"> <f:facet name="header"> <h:outputText value="City" /> </f:facet> <h:outputText value="#{customer.city}" /> </p:column> </p:dataTable> </h:form> That gives me this: And here's the filter in action: Behind this, I have: import com.mycompany.mavenproject3.entities.Customer; import java.io.Serializable; import java.util.List; import javax.annotation.PostConstruct; import javax.ejb.EJB; import javax.faces.bean.RequestScoped; import javax.inject.Named; @Named(value = "resultManagedBean") @RequestScoped public class ResultManagedBean implements Serializable { @EJB private CustomerSessionBean customerSessionBean; public ResultManagedBean() { } private List<Customer> customers; @PostConstruct public void init(){ customers = customerSessionBean.getCustomers(); } public List<Customer> getCustomers() { return customers; } public void setCustomers(List<Customer> customers) { this.customers = customers; } } And the above refers to the EJB below, which is a standard EJB that I create in all my Java EE 6 demos: import com.mycompany.mavenproject3.entities.Customer; import java.io.Serializable; import java.util.List; import javax.ejb.Stateless; import javax.persistence.EntityManager; import javax.persistence.PersistenceContext; @Stateless public class CustomerSessionBean implements Serializable{ @PersistenceContext EntityManager em; public List getCustomers() { return em.createNamedQuery("Customer.findAll").getResultList(); } } Only problem is that the columns are only sortable after the first time I use the filter.

• How do I commit changes to a text file on button press?

  - by boywithaxe

  I've written a small app that creates a GUI for setting up uShare. Currently it depends heavily on the 'w' (write) and 'a' (append) functions to generate/edit ushare.conf file. But I've been trying to find a way for the app to store all the changes until a save button is pressed, and only then committing them to the actual file. I think that would be the best way of getting around having the user press enter every time they change any field (and indeed allow for GtkCheckButton).

• How to automatically switch monitors with my laptop dock

  - by Cas

  I have a Dell Precision M4300 with a Dell Dock PRO1X running Ubuntu Natty. When I have the laptop docked the lcd display is off and I use two external monitors however when I undock the laptop it does not switch to the laptop screen. The same happens when I dock the laptop, it does not switch to the external monitors. If I reboot the laptop it will choose the correct setup but it will not automatically change monitors with Ubuntu running. My Xorg.conf

• CUPS - Configuring default printer options

  - by user193661

  I'm using a CUPS printer and trying to set the default options for the printer using /etc/cups/ppd and /etc/cups/printers.conf but I don't see a complete list of available options. Currently I'm trying Option page-top 2 Option page-bottom 2 Option scaling 95 My end goal is getting the printer to stop cutting off the top and bottom page content. I would like to automatically scale the content to fit on the page size being used (default "letter") if possible and if not, resume printing on another page without removing any of the content.

• Dynamic Bind9 + DHCP

  - by AcidRod75

  i have been working on setup a server for my internal network, so far i have a working isc-dhcp-server that can upgrade a chrooted BIND9 (on the same machine), i need to add some static entries on the DNS, so users can resolve the websites that resides in our DMZ. What i had tryed all ready was to modify the /etc/bind/named.conf.local with this info: // // Do any local configuration here // // Consider adding the 1918 zones here, if they are not used in your // organization //include "/etc/bind/zones.rfc1918"; key DHCP_UPDATER { algorithm HMAC-MD5.SIG-ALG.REG.INT; secret "MySuperSecretHash"; (this is not the real value BTW) }; zone "quality.internal" IN { type master; file "/var/lib/bind/quality.internal.db"; allow-update { key DHCP_UPDATER; }; }; zone "0.10.10.in-addr.arpa" { type master; file "/var/lib/bind/rev.10.10.0.in-addr.arpa"; allow-update { key DHCP_UPDATER; }; }; logging { channel query.log { file "/var/log/named/query.log"; severity debug 3; }; category queries { query.log; }; }; --- EOF ---- then i added this 2 entries: zone "ourserver.internal" IN { type master; file "/var/lib/bind/ourserver.internal.db"; }; zone "0.16.172.in-addr.arpa" { type master; file "/var/lib/bind/rev.172.16.0.in-addr.arpa"; }; ---- EOF ---- So.. i created the files ourserver.internal.db and rev.172.16.0.in-addr.arpa placed them BOTH in /var/lib/bind/ and changed the permisions so the bind user can access them, restated the service... when i do a NSLOOKUP www.ourserver.internal i get: Server: 127.0.0.1 Address: 127.0.0.1#53 ** server can't find www.ourserver.internal: NXDOMAIN BUT when i do a reverse lookup.... Server: 127.0.0.1 Address: 127.0.0.1#53 5.0.16.172.in-addr.arpa name = www.ourserver.internal I do not understand what's wrong. Some help with this will save me from installing a new DNS server at the DMZ JUST to host internal site names- TY in advance BTW: the server i'm using has Ubuntu Server 11.10 fully patched.

• Upgrade to 11.10 caused rt2800usb module to be blacklisted

  - by Shevek

  I just upgraded from Kubuntu 11.04 to 11.10, and I noticed that after the upgrade my USB wireless card was no longer recognized. It turns out that the rt2800usb module had been added (automatically, I assume, unless previously the module had been loading despite being blacklisted) to /etc/modprobe.d/blacklist.conf. I re-enabled the wireless card by commenting out the blacklist line and adding rt2800usb to /etc/modules, but I was wondering if there was a reason for rt2800usb being added to the blacklist.

• Why are trees shining in background?

  - by Kinected

  Currently I am creating a forest scene in the dark, and the trees are shining far away, but when I get close they are fine. I have the shaders set to "Nature/Tree Soft Occlusion [bark/leaves]", but they are still rendering strange far away, but close they are fine. I tried placing the trees in a folder named "Ambient-Occlusion" like said here, but no luck. Also fog is turned off. Thanks in advance.

• twin view on gnome when monitor is unplugged

  - by james t

  i have a macbook pro which is often connected to a monitor, twin view on gnome works pretty well, but a problem arises when i disconnect the monitor, any window that resided on that workspace is no longer available. another issue is when i start my computer when a monitor is not present, because xorg.conf file has the monitor configuration in it, my mouse pointer often disappears in the other monitor's virtual space, as if it is currently plugged, osx deals with this issue elegantly by refreshing the display every time a plug in/out occurs, is there anything similar that can be done in linux ?

• Uninstall Caribou?

  - by Icedrake

  I just installed the Gnome Tweak Tool in order to change my icon theme to Faenza, but it seems to have installed some other program named Caribou, which I think is an onscreen keyboard program, with it. This is absolutely useless for me, and frankly, I hate the fact that it was installed silently and without my permission. When I go to uninstall it, it says that it's part of gnome-shell and requires the un-installation of that as well. What do I do?

• 403 Forbidden for /home/my-username/Dropbox/Hemsidor as directory root

  - by Erik Edgren

  I'm trying setup Apache to point the directory root to /home/my-username/Dropbox/Hemsidor but when I go to localhost I got 403 Forbidden. I don't have any .htaccess file in the home directory (Hemsidor) so I don't know what the problem is. I have tested to add Options +FollowSymLinks -SymLinksIfOwnerMatch in my httpd.conf file and then restarted Apache but with no luck. What's wrong? Thanks in advance.

• Temporary Object Caching Explained

  - by Paul White

  SQL Server 2005 onward caches temporary tables and table variables referenced in stored procedures for reuse, reducing contention on tempdb allocation structures and catalogue tables.  A number of things can prevent this caching (none of which are allowed when working with table variables): Named constraints (bad idea anyway, since concurrent executions can cause a name collision) DDL after creation (though what is considered DDL is interesting) Creation using dynamic SQL Table created in a...(read more)

• What is the architectural name for the set of data that enables UI choices?

  - by Richard Collette

  I have separate service methods that fetch business object data and the data for UI selection input such as radio buttons, check-boxes, combo-boxes, etc. I want to name my service methods that fetch the selection data appropriately. I am assuming that Model and ViewModel would not be part of the name because the selection data is but a portion of the Model or ViewModel. What might this set of data be named such that I can name my service method?

• How do I create a Unicode databases in PostgreSQL 8.4?

  - by wildpeaks

  I installed the postgresql-8.4 package with default options. Everything worked fine, however I can't seem to manage to create unicode databases: -- This doesn't work createdb test1 --encoding UNICODE -- This works createdb test2 The error message, createdb: database creation failed: ERROR: new encoding (UTF8) is incompatible with the encoding of the template database (SQL_ASCII) is a bit puzzling because (afaik) I don't use a template for creating the new db, or is it implicitely referring to the default "postgres" database for some reason ? Or maybe I'm missing a setting in a .conf file ?

  - by Romeo

  I am trying to move a group of files with in a group of folders named recup_dir.1 through recup_dir.535 into a single folder so that all the files will be out of the folders and just in the single folder.

I just want it to automate the copying and moving of the files rather than do it manually.
