  • How to make my proxy settings change depending on the network I connect to?

    - by Little Jawa
    My company's corporate network requires me to set a network proxy to access the net, but when I am anywhere else, I don't need it. The proxy settings in Ubuntu (System - Preferences - Proxy server) allowed me to create "locations" that I can manually select. Then I have a "default" location (with no proxy) and a "work" location (with my company's proxy in it). Is there a way to make Ubuntu automatically select the "work" location based on the connection I'm using? I thought I could use the IP subnet (very specific) to detect where I am, but I have no idea how to set it up... Edit: I really need to have the proxy settings set at the system level. All my network connections (IMAP, SMTP, chat, etc) need to go through the proxy. Not only the web browser.

  • Do you use a grid system when designing a web page?

    - by johnny
    I'm trying to figure out why I would use a grid system. I have read some but I just don't get it. I'm used to just putting stuff in html on a page and beind done with it but I have a new project and would like to use a grid because apparently it is a best practice. I read in one article referenced in another SO question and it said that grid design was in all sorts of development, even application form design. That made me think of things like snap to grid, etc. and I didn't know if the grid in the web design sphere was the same. I was hoping someone could give me a brief but not overly complicated view and not a link to Google which I have used already. Thank you for any help.

  • google analytics statistics

    - by colmcq
    I am compiling a report for a client using google analytics. I have observed that the client has unusually good page view times (5 mins) and excellent bounce rates (<25%). I need to reference research data that validates my assertion that these figures are excellent compared to an industry standard (the industry is ecommerce and gaming). Can you direct me to any published research data that specifies normal bounce rates and page view times for this industry?

  • System.Data.Sqlclient.Sqlexception: Line1 incorrect syntax ...

    - by marocanu2001
    Given a SqlConnection, a SqlCommand if you need to execute a stored procedure it is enough to specify the stored procedure name as the CommandText and it will work. Now the surprise is that if you also add parametres, you get this creepy error: SqlException: Line 1 incorrect syntax near [storedProcedureName]. The quick fix is to specify the CommandType to be StoredProcedure.

  • Why is Wine not installable on my system?

    - by RawX
    So I upgraded on a fresh install to Ubuntu 12.10, not beta, and I've tried installing wine many many times now many different ways but the jist of it is this: This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time. The following packages have unmet dependencies: wine: Any ideas? It won't let me install the dependencies either it says it needs another set of dependencies to install them -_- im on asus kj50 64bit os dual boot with windows 7 sudo apt-get install wine1.5 Reading package lists...

  • RPG Equipped Item System

    - by Jimmt
    I'm making a 2d rpg with libgdx and java. I have an Inventory class with an Array of Items, and now I want to be able to equip items onto the player. Would it be more managable to do have every item have an "equipped" boolean flag have an "equipped" array in the player class have individual equipped fields in player class, e.g. private Item equippedWeapon; private Item equippedArmor; public void equipWeapon(Item weapon){ equippedWeapon = weapon; } Or just another way completely? Thanks.

  • Why not System.Void?

    - by Stewart
    I have no practical reason for knowing this answer, but I'm curious anyway... In C#, trying to use System.Void will produce a compilation error: error CS0673: System.Void cannot be used from C# -- use typeof(void) to get the void type object As I understood it, void is simply an alias of System.Void. So, I don't understand why 'System.Void' can't be used directly as you might with 'string' for 'System.String' for example. I would love to read an explanation for this! Incidentally, System.Void can be successfully used with the Mono compiler, instead of Microsoft's .Net, and there it appears equivalent to using the void keyword. This must therefore be a compiler-enforced restriction rather than a CLR restriction, right?

  • Pointers to implementing a taxonomy system?

    - by petsagouris
    I am taking part in the development of a PHP CMS (yeah I know you are like, meeh). It is currently using simple tags for tagging content. What I want to do is push the whole thing to using Taxonomy but I am not sure on what to pay attention to, or how to go about structuring the whole vocabularies/terms. I'd love to be able to keep the user interaction close to that of the current simple tags and at the same time allow for more advanced usage by power users. The Drupal and the Wordpress taxonomy systems are being reviewed at the moment and they provide valuable resources. Nevertheless, it could be that someone has some simpler and more appropriate thoughts on this matter.

  • How to add ONLY system tray icon to application?

    - by badpanda
    I am developing an application that will be running behind the scenes in Windows and would like to put an icon in the system tray for troubleshooting purposes (simple way for users to tell if the app is running). There is no other UI for the application, and the icon does not need to have any functionality as of right now. All of the solutions I have found as of yet involve creating a form. I am wondering if there is a way to simply add a class to my current C# code that allows me to control the icon, rather than doing the whole 'make a form, set it to be invisible....' nonsense that seems to be the popular suggestion on the forums. Something along the lines of the way that UI control is done in say, Swing for Java. I would really appreciate any ideas! (Sorry if this is a n00b question...I haven't used C# before...) Thanks! badPanda

  • Ubuntu 14.04 Fatal Exception

    - by user286534
    I use Ubuntu 14.04, 64-bit. I installed Virtualbox and was testing another Linux OS (Deepin). My system froze and I could not get to a TTY session to reboot. I had to do a hard restart and when Ubuntu restarted I got various error codes one of which was "kernel panic - fatal exception in interrupt" Booting to Advance mode and attempting repairs did not work (fsck, grub repair, etc) I reinstalled Ubuntu and chose the option to keep my files intact. I can now access my system but many programs I have installed do not work. My question is; I have a Deja-Dup backup (but only of my Home directory), is it better to restore my backup files or do I have to reinstall all of my programs? The weird thing is, the programs I verified using the Software Center to see if they were installed are checked as installed, but won't appear in Dash.

  • Adding icon to the system tray (notification area)

    - by Moma Antero
    Hello, I have a small audio recording application programmed with GTK/GDK. (see picture). And I would like to add a tray-icon for it so users can control the application window and recording from it. Adding a tray icon: I have planned to use the GtkStatusIcon class for this task. Ref: http://library.gnome.org/devel/gtk/2.11/GtkStatusIcon.html Is GtkStatusIcon the recommended solution that also works in Ubuntu's Unity and in the GNOME 3.0 desktop? I already googled a bit and found a good example on GtkStatusIcon. Could I also use Libindicator for this task? Ref: https://launchpad.net/libindicator

  • Implementing cache system in Java Web Application

    - by TGM
    I worked with JPA (Eclipselink implementation) and Hibernate. As I understand these two have great caching systems. I am interested in caching in a Web application and in order to better understand the process I'm trying to implement something on my own. Sadly, I cannot find any in depth documentation about this subject. I'm interested in things like high scalability, sharing memory on different machines and other important theoretical matters. Is there any tutorial or open project I could check out? Thank you! *LE: * I want to cache DB information in POJOs just like JPA or Eclipselink
