• Canon MX870 printer only shows "Processing" on the status LCD

  - by Nick

  I had my Canon MX870 installed perfectly fine in 11.10, but since upgrading to 12.04, it no longer works. The printer is recognized in print settings and when I attempt to print a test page, the printer LCD displays a "Processing" message, but then it disappears and nothing happens. Here are my logs (note that printing did not succeed despite the access logs showing success): # /var/log/cups/access_log localhost - - [22/May/2012:12:29:35 -0400] "POST /printers/Canon-MX870 HTTP/1.1" 200 412 Print-Job successful-ok - # /var/log/cups/error_log W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-Gray..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-RGB..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateDevice: org.freedesktop.ColorManager.AlreadyExists:device id 'cups-Canon-MX870' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-Gray..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-RGB..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateDevice: org.freedesktop.ColorManager.AlreadyExists:device id 'cups-Canon-MX870' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-Gray..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-RGB..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateDevice: org.freedesktop.ColorManager.AlreadyExists:device id 'cups-Canon-MX870' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-Gray..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-RGB..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateDevice: org.freedesktop.ColorManager.AlreadyExists:device id 'cups-Canon-MX870' already exists

• SharePoint 2010 BDC Model Deployment Issue: “The default web application could not be determined.”

  - by Jan Tielens

  Yesterday I tried to deploy a Business Data Connectivity Model project created in Visual Studio 2010 to my SharePoint 2010 test server (all RTM versions), but during the deployment of the solution, SharePoint threw my following error: Add Solution:  Adding solution 'BCSDemo2.wsp'...  Deploying solution 'BCSDemo2.wsp'...Error occurred in deployment step 'Add Solution': The default web application could not be determined. Set the SiteUrl property in feature BCSDemo2_Feature1 to the URL of the desired site and retry activation.Parameter name: properties A little bit of searching on the internet taught me that I was not the only one having this issue, actually Paul Andrew describes how to solve it in this post. Although Paul describes what to do, his explanation is not, let’s say, very elaborate. :-) So let’s describe the steps a little bit more in detail: Create a new Business Data Connectivity Model project in Visual Studio 2010 and (optionally) implement all your code, change the model etc. When you try to deploy you get the error mentioned above. To fix it, in the Solution Explorer, navigate to and open the Feature1.Template.xml file (the name could be different if you decided to give your feature a different name of course). Add the following XML in the Feature element that’s already there (replace the Value with the URL of your site of course):  <Properties>    <Property Key='SiteUrl' Value='http://spf.u2ucourse.com'/>  </Properties>The resulting XML should look like:<?xml version="1.0" encoding="utf-8" ?><Feature xmlns="http://schemas.microsoft.com/sharepoint/">  <Properties>    <Property Key='SiteUrl' Value='http://spf.u2ucourse.com'/>  </Properties></Feature> Deploy the solution, now without any issues. :-) What happens now, is that when Visual Studio creates the SharePoint Solution (the WSP file), it will use the Feature template XML to generate the Feature manifest, which will now include the missing property.

• Authenticating Mountain Lion over Ubuntu 12 LDAP [closed]

  - by Sam Hammamy

  Possible Duplicate: Ubuntu OpenLDAP and Mac OS X Roaming Profiles I've installed slapd on Ubuntu 12 after a long long day of trial and error. I've added the apple.ldif schema, and the samba.ldif schema, plus a test user. Last week, I had installed slapd on Ubuntu 11, and was able to authenticate against it from OS X Lion after finding the following blog post: Fixing OpenLDAP Authentication on OS X Lion This suggests running the following commands to fix the authentication problem /usr/libexec/PlistBuddy -c "add ':module options:ldap:Denied SASL Methods:' string CRAM-MD5" /Library/Preferences/OpenDirectory/Configurations/LDAPv3/yourldapserver.plist /usr/libexec/PlistBuddy -c "add ':module options:ldap:Denied SASL Methods:' string NTLM" /Library/Preferences/OpenDirectory/Configurations/LDAPv3/yourldapserver.plist /usr/libexec/PlistBuddy -c "add ':module options:ldap:Denied SASL Methods:' string GSSAPI" /Library/Preferences/OpenDirectory/Configurations/LDAPv3/yourldapserver.plist However, I ran these commands on OS X Mountain Lion, and I am still unable to authenticate. I can't even use the Directory Editor app to examine the AD. I am however able to bind to the server via python-ldap's ldap.simple_bind_s('cn=admin,dc=foo,dc=net,'secret'). The error I am getting when trying to use Director Editor is Error Code (5000)

• In SASL authentication, are the messages between a particular client and server the same every time

  - by karenc

  I wrote a test client and server using the Cyrus SASL library, and I'm manually forcing it to select GSSAPI as the mechanism. While debugging, I printed the md5sum of each message as it was passed between the two. I noticed that the sequence seems to be the same every time I connect. That is, if the message sequence on the first negotiation was clientMessage1, serverResponse1, clientMessage2, etc... to successful authentication, if I then restart my client, the same clientMessage1, serverResponse2, clientMessage2,etc... sequence is repeated. It seems to me like it would be a security concern. Is this the correct behavior and if so, should I be wrapping these communications in TLS or something?

• High CPU usage compared to WinXP. Common aps and actions use 100% CPU cycles

  - by Jopower

  I'm running Lubunto 14.04.1 LTS. PC is a 2004 HP ze4200 laptop: 1.8 ghz Celeron M with 1 gb RAM and 80 gb drive. Was running fine on WinXP SP3 and I cleaned the drive off to test Lubuntu 14 LTS. No anti-virus is installed yet. I enabled the CPU resource monitor to see how various programs drag the OS. Using Firefox 31 online right now, I see doing basic functions like openning a new tab and scrolling down a page are using 100% CPU time, ocassionally for 10-30 seconds. In fact some pretty basic aps like Leafnote hit 100% for a second. Wordpad never did that. Lubuntu Software Center locks things up at 100% for 10 seconds. Just typing here shows a 60-80% spike every character. Running the mouse around the screen for 10 seconds results in a sustained 100% load during that time. Right now, if I let the PC rest just idling Firefox and not doing anything with it, CPU use bounces from 20-40% all by itself. WinXP idles at 2-10% and it's considered not good for it to be above 20%... something odd must be happening. Sure, XP will give similar higher CPU cycles with program use, but it's not locking and slogging like this. Lubuntu is supposed to be a light OS and by memory usage it is and I'm happy since this is an old PC maxed for memory upgrades. However, being used to doing some tuning and wary of abnormalities going on in the background, the CPU use indicates things going on that I want to know about and perhaps apply a tweek or two. Recommendations are appreciated. And this 300 point "new tags" restriction bites!

• Testing for Auto Save and Load Game

  - by David Dimalanta

  I'm trying to make a simple app that will test the save and load state. Is it a good idea to make an app that has an auto save and load game every time the newbies open the first app then continues it on the other day? I'm trying to make a simple app with a simple moving block sprite, starting at the center coordinate. Once I moved the sprite to the top by touch n' drag, I touch the back key to close the app. I expected that once I re-open the app and the block sprite is still at the top. But instead, it goes back to the center instead. Where can I find more ways to use the preferences or manipulating by telling the dispose method to dispose only specific wastes but not the important records (fastest time, last time where the sprite is located via coordinates, etc.). Is there really an easy way or it has no shortcuts but most effective way? I need help to expand more ideas. Thank you. Here are the following links that I'm trying to figure it out how to use them: http://www.youtube.com/watch?v=gER5GGQYzGc http://www.badlogicgames.com/wordpress/?p=1585 http://www.youtube.com/watch?v=t0PtLexfBCA&feature=relmfu Take note that these links above are codes. But I'm not looking answers for code but to look how to start or figure it out how to use them. Tell me if I'm wrong.

• Where is the SQL Azure Development Environment

  - by BuckWoody

  Recently I posted an entry explaining that you can develop in Windows Azure without having to connect to the main service on the Internet, using the Software Development Kit (SDK) which installs two emulators - one for compute and the other for storage. That brought up the question of the same kind of thing for SQL Azure. The short answer is that there isn’t one. While we’ll make the development experience for all versions of SQL Server, including SQL Azure more easy to write against, you can simply treat it as another edition of SQL Server. For instance, many of us use the SQL Server Developer Edition - which in versions up to 2008 is actually the Enterprise Edition - to develop our code. We might write that code against all kinds of environments, from SQL Express through Enterprise Edition. We know which features work on a certain edition, what T-SQL it supports and so on, and develop accordingly. We then test on the actual platform to ensure the code runs as expected. You can simply fold SQL Azure into that same development process. When you’re ready to deploy, if you’re using SQL Server Management Studio 2008 R2 or higher, you can script out the database when you’re done as a SQL Azure script (with change notifications where needed) by selecting the right “Engine Type” on the scripting panel: (Thanks to David Robinson for pointing this out and my co-worker Rick Shahid for the screen-shot - saved me firing up a VM this morning!) Will all this change? Will SSMS, “Data Dude” and other tools change to include SQL Azure? Well, I don’t have a specific roadmap for those tools, but we’re making big investments on Windows Azure and SQL Azure, so I can say that as time goes on, it will get easier. For now, make sure you know what features are and are not included in SQL Azure, and what T-SQL is supported. Here are a couple of references to help: General Guidelines and Limitations: http://msdn.microsoft.com/en-us/library/ee336245.aspx Transact-SQL Supported by SQL Azure: http://msdn.microsoft.com/en-us/library/ee336250.aspx SQL Azure Learning Plan: http://blogs.msdn.com/b/buckwoody/archive/2010/12/13/windows-azure-learning-plan-sql-azure.aspx

• Improving the performance of a db import process

  - by mmr

  I have a program in Microsoft Access that processes text and also inserts data in MySQL database. This operation takes 30 mins or less to finished. I translated it into VB.NET and it takes 2 hours to finish. The program goes like this: A text file contains individual swipe from a corresponding person, it contains their id, time and date of swipe in the machine, and an indicator if it is a time-in or a time-out. I process this text, segregate the information and insert the time-in and time-out per row. I also check if there are double occurrences in the database. After checking, I simply merge the time-in and time-out of the corresponding person into one row only. This process takes 2 hours to finished in VB.NET considering I have a table to compare which contains 600,000+ rows. Now, I read in the internet that python is best in text processing, i already have a test but i doubt in database operation. What do you think is the best programming language for this kind of problem? How can I speed up the process? My first idea was using python instead of VB.NET, but since people here telling me here on SO that this most probably won't help I am searching for different solutions.

• Use external speakers with laptop hooked to separate monitor?

  - by lhan16

  I have a laptop with a set of external speakers hooked up to it on my computer desk. The speakers use the standard 3.5mm audio (headphones) jack. The speakers work fine, but I've recently added a separate monitor to my laptop via HDMI. With the monitor hooked up to my laptop and the speakers still hooked up to the laptop, sound will only come out of the built-in monitor speakers. When I look at my audio settings, there are three different "audio playback devices" showing up, but only the built-in monitor speakers make noise when I click "test" (and I hear nothing when I set any of the other devices as the default. Does anyone know how I can still use my external speakers when using a separate monitor with my laptop? I'm hoping there is a solution that doesn't require the laptop to be open or closed, because I use both scenarios. I came across this post, but it doesn't look like they had much luck.

  I have added a cert to my application cacerts file. The new cert is issued to one DNS(abc.com) and they have added few other DNS(XYZ.com, TEST.com) to the SAN attribute while creating. I tried accessing one of the DNS(XYZ.com) given in SAN attribute, it throws me the below mentioned error. <Certificate chain received from XYZ.com failed hostname verification check. Certificate contained abc.com but check expected XYZ.com> If we have more DNS for an application, Do we need to generate cert for every single DNS?

• Glassfish with Webservices on non default port

  - by Rick

  I have a simple web service that I created that deploys perfectly on a default Glassfish V2.1 install on both a windows and a linux system. HOWEVER, In the production environment, Glassfish has the default port for the domain changed from port 8080 to port 80. Now when I try to deploy the web service it will not deploy to the server. The production server is brand new and only was a few webpages on it. Other than the port everything else seems to be the same. I cannot change the port on the production server. In fact I tried to change the port on the linux test server tfrom 8080 to port 80 and I get the same result as the production server. Any ideas - other than don't use glassfish? :)

• What changes can be made to a Microsoft Account using net user on Windows 8?

  - by nhinkle

  In Windows 8, you can log on with a local account or with a Microsoft Account. Both types show up in the Users control panel, but there are different options that you can change for each type. An administrator can change basically any aspect of a local user - name, password, access level, etc. For a Microsoft Account, you can only change the access level (admin/standard) or remove the account. From the command line though, there don't appear to be any restrictions on what you can do a Microsoft Account. Using the net user tool or the Local Users and Groups MMC snap-in, it looks like an administrator would be able to change the password, display name, profile path, etc. of Microsoft Accounts (as well as local accounts of course). Will these commands actually work when applied to a Microsoft Account? Will using them in some way break the link to the Microsoft Account, or will nothing happen at all? I'm hesitant to test since I don't want to mess up my account permanently.

• BizTalk 2009 - The Community ODBC Adapter: Installation

  - by Stuart Brierley

  I have previsouly detailed the installation of MySQL, the configuration of MySQL and the installation of the ODBC Data Connector for MySQL.  The reason I needed to install and configure these servers was to provide a test environment for a BizTalk Server 2009 solution I am working on where BizTalk will be querying and populating a MySQL database. To do this I then needed to install and add the Community ODBC adapter from Two Connect: "The Community BizTalk Adapter for ODBC is based on the code that was first made available on GotDotNet a few years ago. TwoConnect has refreshed this code, added an installer, and tested it against the latest BizTalk editions. We are releasing the updates back to the BizTalk developer, user and partner community as part of our ongoing community intitiatives. This is the second adapter package that TwoConnect makes available to the community after the very succesful release of the BizTalk WSE 3 adapter a couple of years ago. This adapter is useful in all ODBC based integration scenarios. The following are the new features added and fixes made to the old code base on GotDotNet." Detailed below are the installation instructions for this adapter.  Downloading and running the installer will load up the splash screen. Next you need to select the installation location for the adapter. You then need to confirm the installation following which you will be shown the installation progress. Assuming all has gone well you should see the installation complete screen. Once the installation has completed successfully you will then need to add the adapter to your BizTalk Server.  To do this open the BizTalk Administration console, expand the Platform Settings and right click on Adapters then select New\Adapter. You should then be able to select the ODBC adapter and choose the display name for the adapter. This adapter will then be shown in the BizTalk Administration console. Next I will be looking at using the ODBC Adapter when: Generating schemas Creating a receive port Creating a send port

• Warning: E-Business Suite Issues with Sun JRE 1.6.0_18

  - by Steven Chan

  Users need a Java client to run the Forms-based content in Oracle E-Business Suite.  With Oracle JInitiator 1.3 out of Premier Support as of July 2009, Apps users must run the native Sun Java Runtime Engine (JRE) to access this content.In early 2008 we relaxed our certification and support policy for the use of the native Sun JRE clients with the E-Business Suite. The policy reflected a switch from certifying specific JRE versions for the E-Business Suite to specifying minimum versions, instead. This permits E-Business Suite users to run any JRE release above following minimum certified levels, even later ones that Oracle hasn't explicitly tested with the E-Business Suite: JRE 1.5.0_13 and higherJRE 1.6.0_03 and higherUnder our current policy, Oracle E-Business Suite end-users can upgrade their JRE clients whenever Sun releases a new JRE release on either the 1.5 or 1.6 versions. EBS users do not need to wait for Oracle to certify new JRE 1.5 or 1.6 plug-in updates with the E-Business Suite.Known E-Business Suite Issues with JRE 1.6.0_18We test every new JRE release with both E-Business Suite 11i and 12.  We have identified a number of issues with JRE 1.6.0_18.  If you haven't already upgraded your end-users to JRE 1.6.0_18, we recommend that you to keep them on a prior JRE release such as 1.6.0_17 (6u17).

• Capistrano deploying to different servers with different authentication methods

  - by marimaf

  I need to deploy to 2 different server and these 2 servers have different authentication methods (one is my university's server and the other is an amazon web server AWS) I already have running capistrano for my university's server, but I don't know how to add the deployment to AWS since for this one I need to add ssh options for example to user the .pem file, like this: ssh_options[:keys] = [File.join(ENV["HOME"], ".ssh", "test.pem")] ssh_options[:forward_agent] = true I have browsed starckoverflow and no post mention about how to deal with different authentication methods this and this I found a post that talks about 2 different keys, but this one refers to a server and a git, both usings different pem files. This is not the case. I got to this tutorial, but couldn't find what I need. I don't know if this is relevant for what I am asking: I am working on a rails app with ruby 1.9.2p290 and rails 3.0.10 and I am using an svn repository Please any help os welcome. Thanks a lot

• Why "object reference not set to an instance of an object" doesn't tell us which object?

  - by Saeed Neamati

  We're launching a system, and we sometimes get the famous exception NullReferenceException with the message Object reference not set to an instance of an object. However, in a method where we have almost 20 objects, having a log which says an object is null, is really of no use at all. It's like telling you, when you are the security agent of a seminar, that a man among 100 attendees is a terrorist. That's really of no use to you at all. You should get more information, if you want to detect which man is the threatening man. Likewise, if we want to remove the bug, we do need to know which object is null. Now, something has obsessed my mind for several months, and that is: Why .NET doesn't give us the name, or at least the type of the object reference, which is null?. Can't it understand the type from reflection or any other source? Also, what are the best practices to understand which object is null? Should we always test nullability of objects in these contexts manually and log the result? Is there a better way?

• How to separate Hyper-V Private network from the External network

  - by Ron Ratzlaff

  I am setting up a virtual test lab and I configured a domain controller VM running Windows 2008 R2 on my Hyper-V 2008 R2 server. I needed to download and install updates on it so I added an External NIC adapter and got that done. However, systems on my actual real physical domain were pulling IPs from this server and that was a big oopsy on my part so I immediately removed the External NIC adapter until I could find out how to go about keeping the Private and the External separate. If someone from the Server Fault community can help with this since I am pretty new to this, I would be very grateful. Thanks everyone.

• Modular programming is the method of programming small task or programs

  Modular programming is the method of programming small task or sub-programs that can be arranged in multiple variations to perform desired results. This methodology is great for preventing errors due to the fact that each task executes a specific process and can be debugged individually or within a larger program when combined with other tasks or sub programs. C# is a great example of how to implement modular programming because it allows for functions, methods, classes and objects to be use to create smaller sub programs. A program can be built from smaller pieces of code which saves development time and reduces the chance of errors because it is easier to test a small class or function for a simple solutions compared to testing a full program which has layers and layers of small programs working together.Yes, it is possible to write the same program using modular and non modular programming, but it is not recommend it. When you deal with non modular programs, they tend to contain a lot of spaghetti code which can be a pain to develop and not to mention debug especially if you did not write the code. In addition, in my experience they seem to have a lot more hidden bugs which waste debugging and development time. Modular programming methodology in comparision to non-mondular should be used when ever possible due to the use of small components. These small components allow business logic to be reused and is easier to maintain. From the user’s view point, they cannot really tell if the code is modular or not with today’s computers.

• release management system - architectural question

  - by Sonic Soul

  Every place i've worked created their own release process, and all of them worked pretty well, however it took pretty good effort (and often a dedicated team) to manage releases. I am currently at a new place, and about to design such a system, however this time the team is very lean and we won't have dedicated resources to releasing. It will be up to development manager until the system is proofed enough for other developers to use. we're using Subversion as code repository, Team City as the build server, Jira issue tracker, Oracle db. I was thinking about writing a basic workflow app, that will let developers create a new manifest which will specify the following items. release details (who, jira issues etc) workflow step (dev, test, uat, prod approved, prod released) source files that last item is where it can get hairy. especially with database scripts. Figured I'd ask if there is a good pattern, or off the shelf product that could help with the database part, or perhaps the whole process. I briefly tested Red Gate Oracle deployment tool, but it didn't work out as well as I had hoped (from 1 day of testing at least) Questions: I think I could get around releasing of our code with something like Octopus Deploy straight from Team City. I am not clear however, how I could create a simple database deployment part, that will track which version of which script (from subversion) has been deployed where. Is there already some utility I could utilize for navigating subversion to choose which scripts should be released, instead of writing one from scratch. I'd just need it to produce some manifest of paths + versions.

• Does JAXP natively parse HTML?

  - by ikmac

  So, I whip up a quick test case in Java 7 to grab a couple of elements from random URIs, and see if the built-in parsing stuff will do what I need. Here's the basic setup (with exception handling etc omitted): DocumentBuilderFactory dbfac = DocumentBuilderFactory.newInstance(); DocumentBuilder dbuild = dbfac.newDocumentBuilder(); Document doc = dbuild.parse("uri-goes-here"); With no error handler installed, the parse method throws exceptions on fatal parse errors. When getting the standard Apache 2.2 directory index page from a local server: a SAXParseException with the message White spaces are required between publicId and systemId. The doctype looks ok to me, whitespace and all. When getting a page off a Drupal 7 generated site, it never finishes. The parse method seems to hang. No exceptions thrown, never returns. When getting http://www.oracle.com, a SAXParseException with the message The element type "meta" must be terminated by the matching end-tag "</meta>". So it would appear that the default setup I've used here doesn't handle HTML, only strictly written XML. My question is: can JAXP be used out-of-the-box from openJDK 7 to parse HTML from the wild (without insane gesticulations), or am I better off looking for an HTML 5 parser? PS this is for something I may not open-source, so licensing is also an issue :(

• Huawei b260a gsm modem not forwarding gre for pptp tunnel

  - by Priit

  I have a huawei gsm modem that does not want to let gre through. The goal is to connect into a pptp server thats behind the huawei. In the modems port forwarding settings theres a ready made profile for pptp (1723). After activating that the MS pptp test tools show that connection is being initiated but no gre packets make it to the server. After taking a closer look into the modems iptables rules theres nothing in there about gre. So I tried making gre rules manualy into forward and preroute chains without any success what so ever. As far as I can tell theres no ip_gre module present on the device is that needed for gre forwarding? Thats what I'm afraid of that it doesn't support gre in NAT but how would I turn it into a bridge? The wan interface is ppp0 so bridging it with eth0 would not work right? Is there some iptables rule I could use to make the modem let all the traffic just straight through?

• BDD (Behavior-Driven Development) tools for .Net

  - by tikrimi

  For several years, I use TDD (Test-Driven Development) to produce code. I no longer plans to work without using TDD. The use of TDD significantly increases code quality, but does not guarantee that the code is the code that corresponds to the requirements specifications (write the "right code" with BDD as opposed to the write "code right" with BDD). Dan North has described in an article in published in 2006 the foundations of the BDD (Behavior-Driven Development). In this article, he introduces the formalism "When Given Then". This formalism is used in all tools dedicated to BDD. This is a short list of open source BDD tools that you can use with .Net : SpecFlow: Here you can find an article in MSDN Magazine and 2 webcasts (http://channel9.msdn.com/posts/ASPNET-MVC-With-Community-Tools-Part-2-Spec-Flow-and-WatiN and http://channel9.msdn.com/posts/ASPNET-MVC-With-Community-Tools-Part-3-More-Spec-Flow-and-WatiN) published on Chanel9. NSpec: This is certainly the most used project. There are many examples on the web. StoryQ: This project is hosted on Codeplex. This small project is very simple to implement and very useful.

• Embedded linux Development learning

  - by user1797375

  I come from a windows background and i am proficient with the .net platform. For work, i need to bring up a custom embedded system platform. We have bought the pandaboard ES as the test platform. The application is to stream images over the wifi. If you think about it, we are building something similar to a netgear router - the only difference being when you log into the device it serves images. Because my background is in windows i am not quite sure how to start off with embedded linux development. in reading through various sites i have come to the conclusion that going to linux as development host is the best option. Can some one point to me in the right direction regarding the set up. I have a windows machine that will be used for development purposes. I can either do a virtual box or setup a partition for linux. But the finer details are what throwing me off..what i need to know is 1) once i install linux what other software do I need - Code blocks, 2) what about toolchain 3) How to debug - through serial port ? 4) Is there a way to send the image built directly to the CF card? Thanks
