• Double entries in the gnome 3 task bar

  - by Mark

  I am running Ubuntu 12.04 with Gnome 3. All was working well except that graphics were slow and even moving a window on the screen seemed slow. I installed the fglrx ati driver. Which seems to have improved matters. But on first login I had all gnome items duplicated. That is my task bar has the ubuntu sign, then says Applications, then places then the ubuntu sign then Aplications and then places. Any application I run produces two icons at the bottom of the screen. This was after a reboot. I rebooted again. Now I have 3!! On the right each set of icons such as printer is also trippled!! See screenshot at http://jetmark.co.uk/Screenshot.png See Dmesg at http://jetmark.co.uk/dmesg.txt Any suggestions welcome. Reboot - now I have 4!! So one set gets added on each reboot. Help!! I am going to be task barred out before long!!

• make mongrel_rails (localhost:3000) visible to a virtual machine

  - by Max Williams

  I develop rails in ubuntu and i just set up a virtualbox windows xp virtual machine for IE testing. I'd like to be able to run mongrel_rails in ubuntu and then jump into the vm to check it out, so i can jump back, make a change, jump into the vm again, reload the page and test it, etc. Is this possible? In this sort of situation in the past i've had to set up an apache server on my dev machine and run mongrel under that, in order to get an externally visible (ie visible to my local network) ip address that i then paste into the address bar of IE in the vm. Is this really necessary? Is there a simpler way? Can i do something with my /etc/hosts or sites-available files to just make up some arbitrary network address which points to localhost:3000 in ubuntu? Or something? thanks, max

• handling activity destruction in multithreaded android app

  - by Jayesh

  Hi, I have a multithreded app where background threads are used to load data over network or from disk/db. Every once in a while user will perform some action e.g. fetch news over network, which will spawn a background AsyncTask, but for some reason user will quit the app (press back button so that activity gets destroyed). In most such scenarios, I make appropriate checks in the background thread after it returns from n/w i/o, so that it won't crash by accessing members of the activity that is destroyed by now. However some corner cases are left where crashes happen, because the background thread would access some member of activity that is now null. Do other Android developers have some generic/recommended framework to handle such scenarios? These are the times when I wish android would have guaranteed termination of all threads when activity destroys (in the same way that regular linux process cleans up when it's quit)... but I guess Android devs had good reasons for not exposing process lifetimes through the api.

• How to write a jUnit test for this class?

  - by flash

  Hi, I would like to know what's the best approach to test the method "pushEvent()" in the following class with a jUnit test. My problem is, that the private method "callWebsite()" always requires a connection to the network. How can I avoid this requirement or refactor my class that I can test it without a connection to the network? class MyClass { public String pushEvent (Event event) { //do something here String url = constructURL (event); //construct the website url String response = callWebsite (url); return response; } private String callWebsite (String url) { try { URL requestURL = new URL (url); HttpURLConnection connection = null; connection = (HttpURLConnection) requestURL.openConnection (); String responseMessage = responseParser.getResponseMessage (connection); return responseMessage; } catch (MalformedURLException e) { e.printStackTrace (); return e.getMessage (); } catch (IOException e) { e.printStackTrace (); return e.getMessage (); } } }

• help in security assignment

  - by scatman

  i have to write a program that sniffs network packets (part1-the simple part). and i have to update the program (part2) so that it will be able to terminate connections. the specific requirements are: construct raw packets by specifying data link layer and network layer information including appropriate source and destination MAC and IP addresses. These packets are intended to terminate the connection. To do so, you should used SOCK_RAW as the socket type to be able to set the header information by yourself. can anybody give me some ideas on the second part? should i hijack the session,apply a dos attack on one of the users?? all i need is some tips of how to terminate the connection. i am using c programming language. and this is a course assignment for the security course.

• Representing xml through a single class

  - by Charles

  I am trying to abstract away the difficulties of configuring an application that we use. This application takes a xml configuration file and it can be a bit bothersome to manually edit this file, especially when we are trying to setup some automatic testing scenarios. I am finding that reading xml is nice, pretty easy, you get a network of element nodes that you can just go through and build your structures quite nicely. However I am slowly finding that the reverse is not quite so nice. I want to be able to build a xml configuration file through a single easy to use interface and because xml is composed of a system of nodes I am having a lot of struggle trying to maintain the 'easy' part. Does anyone know of any examples or samples that easily and intuitively build xml files without declaring a bunch of element type classes and expect the user to build the network themselves? For example if my desired xml output is like so <cook version="1.1"> <recipe name="chocolate chip cookie"> <ingredients> <ingredient name="flour" amount="2" units="cups"/> <ingredient name="eggs" amount="2" units="" /> <ingredient name="cooking chocolate" amount="5" units="cups" /> </ingredients> <directions> <direction name="step 1">Preheat oven</direction> <direction name="step 2">Mix flour, egg, and chocolate</direction> <direction name="step 2">bake</direction> </directions> </recipe> <recipe name="hot dog"> ... How would I go about designing a class to build that network of elements and make one easy to use interface for creating recipes? Right now I have a recipe object, an ingredient object, and a direction object. The user must make each one, set the attributes in the class and attach them to the root object which assembles the xml elements and outputs the formatted xml. Its not very pretty and I just know there has to be a better way. I am using python so bonus points for pythonic solutions

• SQL Server mirroring connection doesnt work

  - by StNickolas

  I have 2 servers srv-erp1 and srv-erp3. I made them mirror on each other. All setup is done by lots of tutorials and examples. But when I call ALTER DATABASE MIRROR_TEST SET PARTNER = 'TCP://srv-erp3:5022' It`s response is: The server network address "TCP://srv-erp3:5022" can not be reached or does not exist. Check the network address name and that the ports for the local and remote endpoints are operational. I go to cmd on srv-erp3 and use netstat -an... this port is listening. I go to cmd on srv-erp1 and use telnet srv-erp3 5022...and its ok to connect. All firewalls are turned off. The only difference in config of srvrs is that srv-erp1 is on Windows Server 2003 R2 x64, and srv-erp3 is on Windows 2008 R2 x64 What can be the reason of this problem? Regards, Dmitry.

• IO.Directory.Exists always returns true

  - by roygbiv

  I am executing a IO.Directory.Exists on a network share from an ASP.NET application running under a specific Application Pool with a specific user account. The call always returns true. I have tried several variations: \\server\share$\directory \\192.168.0.1\share$\directory H:\directory I have checked that directory and share permissions are available to the account. The path does have spaces in it \\server\share$\directory\name name\test test, which should make no difference, however I have read otherwise. I will continue to check permissions, as it does work from my local machine (with the built in VS web-server and I am an administrator on the network), but when deployed to the IIS 6.0 virtual directory, and run under the Application Pool, it does not work.

• How to test a .net application against a proxy?

  - by Pierre-Alain Vigeant

  I need to support the use of proxy on our application that is using WCF connections. We do not have any proxy server on our network and I don't want to disrupt our corporate network by requesting a proxy installation. I was thinking of installing a proxy server on a local virtual machine and configurating Internet Explorer so that it will challenge that proxy. I don't know what proxy software to use (I don't want to install ISA server) and I don't know how to configure one. Does someone have any suggestion for a easy to use software that will require an authentication for any WCF services and do you have any guideline that would be helpful to know when testing a software against a proxy?

Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) I've created a SQL compact database, included it in my application, and can connect to the database fine from other database editors, but within my application im trying using (SqlConnection con = new SqlConnection(Properties.Settings.Default.DatabaseConnection)) { con.Open(); } the connection string is Data Source=|DataDirectory|\Database.sdf I'm stumped, any insight?

• Discovering the default gateway without DHCP

  - by JavaRocky

  A crazy question, but is there anyway to discover the default gateway without DHCP? This would be for a device on a network which does not use DHCP which does not have an IP address as yet. I was thinking if I could discover the default gateway, then i could try to guess an unused ip address then broadcast on the network to see if it's being used. I may be asking for trouble i understand. E.g. if there is already a computer which has a static IP and is shutdown.

• weird access denied issue with WMI

  - by stackunderflow1

  I'm seeing a weird access denied issue with WMI. we're trying to create a diff disk based on a parent vhd in a windows service app that runs under network service (machine account is an admin). everything works fine when we create the diff disk on other machine using wmi - we use an admin user account. however, we cannot do this on a local machine as wmi doesn't take user cred for the local machine. so thought network service account already should have access for this, it seems like it doesn't and even if we run the service under an admin service account, it fails. any pointers???

• C# Threading and Sql Connections

  - by Jonathan M

  I have a method that attempts to update a sql server database in an ASP.NET application. If the update fails, it catches the exception and then queues the update in MSMQ, and then spins up a new thread that will later de-queue the pending update and try again. When the thread starts, it fails to open a database connection because it is attempting to connect using Network Service as the login. The sql connection is using Windows Authentication, and will work outside of the thread. If I put a breakpoint in the code that executes inside the new thread and check the Thread.CurrentPrincipal, it shows the Identity as being the correct user. Why is the sql connection attempting to be opened by the Network Service account? I can elaborate further is necessary. Thanks.

• How do I change careers to become a programmer without spending a lot of money

  - by bgc83

  I'm currently a network engineer, but find myself wanting to get into the world of development. I took a little bit of Java in college, am 27 years old and have been network engineering for 4 years now. I have a mortgage and student loans so going back to school would be difficult. I'm willing to put in however much hardwork is needed around my full time job to learn, but part of me feels I may need actuall schooling to get down some of the advanced concepts. Just looking for a little advice and direction. I have purchased a bunch of the Head First programming books and have begun reading through some of them as I figure out my way into this transition.

• Setting Up TFS Server outside of a domain

  - by Ben

  Hi Im trying to set up TFS 2010 on a machine that is connected to a network, but not on the domain. I am trying to connect this to a SQL Server that is also connected to the network and also not on the domain. When I run through the TFS configuration Wizard and try to connect to the SQL Server, it fails with a message "A connection can not be made...." which looks like it cant see the Server. However when i connect through SQL Management Studio it works when i use SQL Authentication (not Windows Auth). I beleive its failing because TFS needs to connect using Windows Authetication (please correct me if im wrong). I can not add the Windows Authentication for my TFS machine onto the SQL machine becuase they are on different domains (again, pleas correct me if I'm wrong). Does anyone have any suggestions? Thanks.

• I'm getting reports that my app is draining the battery, but only on HTC Incredible.

  - by BenTobin

  Has anyone else noticed behavior specific to the HTC Incredible that might result in an app keeping the device awake and busy? I've received reports that my app is responsible for keeping the device awake and draining the battery, but only from HTC Incredible users. My app responds to a number of Intents that might be related. It has a service that starts on boot, and it also responds to changes in network connectivity. I do use a WakeLock, but I'm careful to release it when I'm done processing, and the WakeLock times out after a couple minutes whether I'm done or not. I've heard that the Incredible may have some connectivity problems, or that some of them do. Could it be that the network is going up and down frequently, triggering my app? Any other ideas? I've asked a user to send me their logs with aLogCat. If they're willing, that may help narrow down the cause.

• OpenSocial and its usages

  - by Paul Knopf

  I have looked for some explanation on the exact usages for the set of standards known as OpenSocial. I need some clarification if I can use OpenSocial like the following. I would like to create one library used to community with an OpenSocial api for use in my website that will not 'behave' like an application described by common sites like facebook and myspace. I'm not making a myspace of facebook application, I'm creating my own website and I want users to be able to find friends. I would like to allow users to store usernames and passwords for various OpenSocial-supported social networks. I would also like to use the api to sync events from my web site to their specified social network. I would also like to allow my users to view a list of friends and invite them. Is it possible to create one library that supports OpenSocial and simple "point" to and social network that supports it to get a list of friends and etc?

• DataGridView live display of datatable using virtual mode

  - by Chris

  I have a DataGridView that will display records (log entries) from a database. The amount of records that can exist at a time is very large. I would like to use the virtual mode feature of the DataGridView to display a page of data, and to minimize the amount of data that has to be transferred across a network at a given time. Polling for data is out of the question. There will be several clients running at a time, all of which are on the same network and viewing the records. If they all poll for data, the network will run very slowly. The data is read-only to the user; they won't be able to edit any of it, just view it. I need to know when updates occur in the database, and I need to update the screen with those updates accordingly using virtual mode. If a page of data a user is viewing contains data that has change, he/she will see those updates on that page. If updates were made to data in the database, but not in the data the user is viewing, then not much really changes on the user screen (Maybe just the scroll bar if records were added or removed). My current approach is using SQL server change tracking with the sync framework. Each client has a local SQL Server CE instance and database file that is kept in sync with the main database server. I use the information from the synchronization event to see if any changes were made to the main database and were sync'ed to the client. I need to use the DataGridView virtual mode here because I can't have thousands of records loaded into the DataGridView at once, otherwise memory usage goes through the roof. The main challenge right now is knowing how to use virtual mode to provide a seamless experience to the user by allowing them to scroll up and down through the records, and also have records update on the fly without interfering with the user inappropriately. Has anybody dealt with this issue before, and if so, where I can see how they did it? I've gone through some of the MSDN documentation and examples on virtual mode. So far, I haven't found documentation and/or examples on their site that explains how to do what I am trying to accomplish.

• ASP.NET - remote screenshot

  - by ufoq

  Hi All, I made a very very simple small app to take screenshot of the desktop and send to network share. About 10 PC's would have this app installed. My idea is, that there will be one dashboard in ASP.NET, which simply shows those screenshots on the webpage. So far, easy stuff. But, because I don't want to clog the network and send the screenshot every 1 minute, I would like to launch the .exe on the remote PC's by demand of ASP.NET user. Unfortunately I haven't found any information (and I'm a complete ASP.NET n00b), how to launch remote executable IN the context of the remote PC (so I won't see screenshots of ASP server :) ) If there is no such possibility, please advise about other way to solve this.

• Where are Wireless Profiles stored in Ubuntu [closed]

  - by LonnieBest

  Where does Ubuntu store profiles that allow it to remember the credentials to private wireless networks that it has previously authenticate to and used? I just replaced my Uncle's hard drive with a new one and installed Ubuntu 10.04 on it (he had Ubuntu 9.10 on his old hard drive. He is at my house right now, and I want him to be able to access his private wireless network when he gets home. Usually, when I upgrade Ubuntu, I have his /home directory on another partition, so his wireless profile to his own network persists. However, right now, I'm trying to figure out which .folder I need to copy from his /home/user folder on the old hard drive, to the new hard drive, so that he will be able to have wireless Internet when he gets home. Does anyone know with certainty, exactly which folder I need to copy to the new hard drive to achieve this?
