• Is it possible to have my desktop loaded before login?

  - by Dims

  I am connecting to the system with Putty (this is Windows SSH client) then running some service in interactive personal mode. For example this is a script to run freeswitch: dims@nebulla:~$ cat freeswitch.sh #!/bin/sh cd ~/bin/freeswitch/bin gnome-terminal -e ./freeswitch & I.e. it is installed in user directory. Also DISPLAY is set to :0 The problem is that I can't use this script until login once. Script responds with dims@nebulla:~$ ./freeswitch.sh dims@nebulla:~$ No protocol specified Failed to parse arguments: Cannot open display: After login, I can do "Switch user" and see login screen but script will be able to run since desktop exists. My question is: is it possible to "preload" my desktop, so that initial situation was as if I loogged in and the went to switch user?

• How to completely uninstall LXDE (12.04)?

  - by Jeremy Lunsford

  I'm trying to remove LXDE from my 12.04 system. I've tried running the following commands (as root from a terminal): apt-get remove lxde apt-get purge lxde apt-get autoremove I've also tried a rather lengthy command that was linked to from another question. However, when I log in, LXDE is still presented as an environment choice, and it still functions perfectly well, as if I've done nothing. I ran the above commands again, but got the following message: package . . . is not installed, so not removed. So, where do I go from here, short of re-installing Ubuntu and all my programs?

• Should I create an Enum mapping to my database table

  - by CrazyHorse

  I have a database table containing a list of systems relevant to the tool I am building, mostly in-house applications, or third-party systems we receive data from. This table is added to infrequently, approx every 2 months. One of these systems is Windows itself, which is where we store our users' LANs, and I now need to explicitly reference the ID relating to Windows to query for user name, team etc. I know it would be bad practice to embed the ID itself into the code, so my question is what would be the best way to avoid this? I'm assuming my options are: create a global constant representing this ID create a global enum containing all systems now create a global enum and add systems to it as & when they are required in the code retrieve the ID from the database based on system name I appreciate this may seem a trivial question, but I am going to have many situations like this during the course of this build, and although we are in complete control of the database I would like to conform to best practice as far as possible. Many thanks!

• How to enable home directory encryption for a particular user?

  - by Ivan

  I prefer to have a dedicated "administrator" user for technical purposes and that was one I've set up during installation. I've also refused to encrypt the home folder of the user. Now, as I've added a user account for my actual work usage I want my (but not the "administrator") home folder to be encrypted. How to turn this on? If it is not possible then how to enable encryption for all users home directories on a system already installed? I've found questions and answers about how to disable it but am not sure how to enable it.

• Assemble static site from templates? (don't want to reinvent the wheel)

  - by raindog308

  I have a site that is 100% static content (no php, just some javascript). There's several "blocks" like the header, menu, footer, etc. that are the same on each page. Rather than do a lot of copy/pasting, I was thinking of some kind of template system where I could run a CLI command (in php, perl, python, shell, whatever) and have it replace all the block tags with the actual block text. I did see some answers in this question, but those seem oriented towards "we provide the style and layout, you provide the text". In my case, I have everything as far as layout, css, etc. - just want to do a glorified sed. Before I invent the wheel, I was wondering if there was a tool out there already.

• Black screen in kernel 3.8 (not 3.5, 3.11, 3.13)

  - by TheDeeno

  I need to use kernel 3.8 to address some docker compatibility issues. However, after installing this kernel when I attempt to boot my machine I get a black screen. The system appears to boot to the login screen (I hear the drum sounds), but the screen remains black. If I boot into recovery mode the video works, but is buggy/slow. In recover mode it looks like it's using the vesa driver. It'd be great if I can force this in normal mode. My machine has an ivy bridge intel processor with integrated graphics What should I do next to troubleshoot this?

• How do I avoid the complexity concerns of frameworks while keeping my team marketable?

  - by Desolate Planet

  When deciding upon how to design a software project with my colleagues, most suggestions tend to be for using specific frameworks "because it's popular in the job market" or "that's the framework that gets recruiters on the phone," and never what I'm looking for which is, "because it's a good fit for the project as it makes the system more adaptive to future changes and makes life easier for developers." I didn't start looking at projects in this way until I started reading up on domain-driven design. I've found that the actual domain is hidden deep under the frameworks used and it's hard to learn the business processes that have been implemented by the software product. Is there a way to marry the two competing goals: getting exposure as a development team while still being able to avoid complexity? Are frameworks that compromise, or are there other solutions out there?

• Disable mobile page redirection for SharePoint 2013

  - by Sahil Malik

  SharePoint, WCF and Azure Trainings: more information SharePoint 2013 (foundation too), detects requests from mobile devices and automatically changes the uRL of the requested non mobile page to its mobile substitute. This logic is now built into SPRequestModule. The mobile view is pretty damned amazing. Even though the set of pages for mobile access is completely different, SharePoint has an entirely separate set of controls for the mobile pages. These are in the Microsoft.SharePoint.MobileControls namespace which inherit from Microsoft ASP.NET controls in the System.Web.UI.MobileControls namespace. These Mobile pages can even use mobile Web Part adapters to mimic the behavior of webparts on mobile webpart pages. Read full article ....

• When I have 6 GB of RAM installed, why is just 3 GB available on Ubuntu?

  - by user842225

  I'm using a laptop with 32-bit Ubuntu 10.04. I used to have only 2 GB of RAM. Today, our IT-support upgraded my laptop to a total of 6 GB of RAM. They told me "Though you do now have 6 GB, when you use your current Ubuntu, you'll only have 3 GB available. You have to install the latest version of 64-bit Ubuntu to enable all of the 6 GB." He was in a hurry to leave without explaining more. I turned on my laptop, used gnome-system-monitor to check, and as he said, it shows I only have 3 GB of RAM. Could someone explain me why? Why do I have just 3 GB available, and why installing a 64-bit version makes all of the 6 GB available?

• google-chrome without loading libnss3? [closed]

  - by 17763

  Possible Duplicate: How do I install Google Chome on legacy 7.10 computer? I am trying to get google-chrome to work on Ubuntu 7.10. I installed it with --force-depends and got it to install, but now when I try to run it, I get this error: /usr/bin/google-chrome: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory Is there a way to still get google-chrome to load even without this dependency satisfied? This is an old system that needs to keep this old 7.10 Ubuntu version and I would like to have google-chrome if possible installed, even if it means no sound or other features that are not compatible.

• My gnome terminal keep opening new window

  - by evan

  I actually want to change the default window position of gnome-terminal in my Ubuntu 12.04 system. After some search, I found some one else use the command gnome-terminal --geometry=120x80+50+50 to set the default position. And I actually don't know where to paste the command, so I pasted it to 'custome command' field of terminal's profile. Now when I open one terminal, it just keep opening new ones and I have no way to stop it other than ctrl+C. I even removed .gconf/gnome-termial/ folder and it didn't worked. Can someone help me?

• Reasons to disable game save during combat (e.g. Mass Effect 2)

  - by Steve V.

  So I've been playing Mass Effect 2 (PC) and one of the things I've noticed is that you can only save your game when you're not engaged in combat. As soon as the first enemy shows up on your radar, the save button is disabled. Once combat is over, save functionality reappears. It seems reasonable to assume that Mass Effect 2 is a state machine, and therefore, the internal state of the program at any moment can be captured and reloaded later. This is basically a solved problem - games have been designed this way since the Half-Life era. It also seems reasonable to assume that BioWare knew what they were doing when they made the decision not to follow this model - it's a tried and true system; BioWare wouldn't have done it the way they did without some good reason. What reasons are there to disable game save functionality during combat?

• How can I extract a list of Minecraft items and recipes?

  - by Sean

  I'm designing a robust system for resolving item dependencies in Minecraft and to do so, I need to maintain a database of items and recipes. Right now, this database has to be hand-crafted (no pun intended); I would like to know if it is possible to somehow query the Minecraft jars (or perhaps more realistically, grep through them) to extract this data automatically. How can this be done? The project is currently in Python, but it can still be ported to Java without much fuss at this stage. (For the curious.)

• What am I risking if I don't update my SDK/JDK and bundled runtime/JRE every time there's a security update?

  - by rob

  It seems like there's a new major security hole patched in Java every other week, and I would assume the same goes for other development platforms. After years of frustration trying to get customers to install and configure a compatible JRE on their systems, we started bundling one with our software. (By bundling, I mean we extract a copy of the JRE in our installation directory--we don't install the JRE and configure it as the system default.) The problem is, it's a hassle having to keep that JRE up-to-date because first we have to retest everything to make sure the update didn't break anything (it has broken some of our third-party dependencies in the past). How seriously, if at all, are we putting our customers at risk if we don't update our SDK/JDK and the runtime/JRE that we bundle with our product every time there's a security update? Is it reasonable to just update on a periodic schedule--say, once every 6 months or so?

• How to resolve ambiguous key sequence?

  - by Rob Mosher

  Using BasKet, I get the following message: Ambiguous Shortcut Detected The key sequence 'Ctrl+1' is ambiguous. Use 'Configure Shortcuts' from the 'Settings' menu to solve the ambiguity. No action will be triggered. 'Ctrl+1' is shown next to 'To-Do' under the 'Tags' menu. If I look in 'Configure Shortcuts' I don't find Ctrl+1 assigned to anything (the tag shortcuts aren't listed at all, leading me to believe their assignment is hard coded). I looked under 'System Preferences Keyboard Shortcuts' and also searched through CompizConfig, but didn't find anything there that might conflict. How do I resolve this keyboard shortcut issue? I'm guessing the particular program or key sequence isn't too important. It looks like it happens with a number of KDE programs (sadly I haven't seen a solution).

• Managing large downloadable content on mobile devices

  - by larromba

  This is a general question of how to best manage large downloadable content on mobile devices. Lets consider a situation whereby a mobile app needs to download a number of very large content items, like HD videos, that are over 500MB but under 2GB. Now, lets assume this content delivery system should be scalable. Would it be a fair assumption that: A reputable cloud service would be needed - if so, what is a reliable and cost effective cloud service for mobile devices based on anyone's experience? Large content downloads should only be attempted over a wifi connection, so the end user doesn't incur large costs, e.g. when travelling. Downloads should carry on in the background if possible, as the user won't want to wait in an app for long periods. If the downloads don't finish, or the OS quits the app, all downloads should carry on when the app is next activated? Are there any other pitfalls anyone may have experienced when managing large content on mobile devices? Thanks.

• cryptsetup partitions not detected at boot

  I installed a fresh 12.04 and tried to mimic what I had for 10.04. swap should be encrypted with a urandom key and there's another partition that will contain home and other directories. # cat /etc/crypttab | grep -v '^#' | grep -v '^$' cryptswap /dev/sda5 /dev/urandom swap encriptado /dev/sda6 # grep -e 'cryptswap' -e 'encriptado' /etc/fstab /dev/mapper/cryptswap swap swap defaults 0 0 /dev/mapper/encriptado /encriptado ext4 defaults 0 0 I also apt-get install cryptsetup When I boot, the system says (try to translate) that either the partition is not found or is not ready. I should wait, press M for manual or S to jump over. What am I missing here?
