• Dual LAN Printing

  - by Christopher

  I want to use Ubuntu 10.10 Server in a classroom, a computer lab whose bandwidth is provided by a local cable ISP. That's no problem, though the school network has an IP printer that I want to use. I cannot reach the printer through the cable Internet. But, I have two network cards. How is it possible to use both networks at once? eth0 (static 192.168.1.254) is plugged into a four-port router, 192.168.1.1. On the public side of the four-port router is Internet provided by the cable company. I also have the classroom workstations plugged into a switch. The switch is plugged into the four-port router. The whole classroom is wired into the cable Internet. The other NIC, eth1, could it be plugged into an Ethernet jack in the wall? It uses the school network, and I might receive by DHCP an IP address like 10.140.10.100, with the printer on maybe 10.120.50.10. I was thinking about installing the printer on the server so that it could be shared with the workstations. But how does this work? Can I just plug eth1 into the school network and access both LANs? Thanks for any insight, Chris

• Laptop drains of quickly with battery

  - by Shyam

  I am a user since years in ubuntu and I have not come across this problem with ubuntu till date. My battery drains off immediately after I unplug my AC power. The options I tried: 1) checked the battery state with : cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: charged present rate: 0 mA remaining capacity: 392 mAh present voltage: 12476 mV Initially it was showing charging state: charging after 5mins it started displaying as charged. ! Based on that if I remove my AC Power it shows low battery notification. 2) When I run acpi : acpi -b Battery 0: Unknown, 9% The battery state shows as unknown. But initially when we plug-in to AC adapter acpi -b Battery 0: Charging, 9%, 13:04:00 until charged 3) When the check the same with : upower -i /org/freedesktop/UPower/devices/battery_BAT0 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:02/PNP0C09:00/PNP0C0A:00/power_supply/BAT0 vendor: HP power supply: yes updated: Thu Nov 1 16:06:40 2012 (20 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging energy: 4.2336 Wh energy-empty: 0 Wh energy-full: 33.1128 Wh energy-full-design: 33.1128 Wh energy-rate: 5.6052 W voltage: 12.474 V time to full: 5.2 hours percentage: 12.7854% capacity: 100% technology: lithium-ion Is the power stats output, It says 5hrs to charge completely, If I charge it even more than 5hrs and unplug the AC power, It again cribs stating LOW BATTERY !! The same thing does not happen with Windows7. Any suggestions/ help will be greatly appreciated.

• Record 8 separate Line IN Channels from M-Audio Delta 1010 Card

  - by Peter Hoffmann

  I want to record the 8 separate Line IN Channels from my M-Audio Delta 1010 Card. The card is recogniced nicely and a can record a single channel via arecord -d 10 -f cd -t wav -D channel1 out2.wav. I've set up the different channels in ~/.asoundrc. Now if I want to record a second channel in parallel (arecord -d 10 -f cd -t wav -D channel2 out2.wav) I get the error arecord: main:564: audio open error: Device or resource busy As I understand the delta 1010 is a single Access Card, so only one application can access it at a time. Is this correct? The next step was to configure a dual channel input in .asoundrc # envy24 channel 1+2 only pcm.test { type plug ttable.0.0 1 ttable.0.1 1 slave.pcm ice1712 } Which works ok when I do a arecord -d 10 -f cd -t wav -D test -c 2 out.wav (BTW can anyone point me to a tool to split a multi channel wav into a file per channel?) But when I want to record the channels separately with (-I option) arecord -d 10 -f cd -t wav -D test -c 2 -I channel1.wav channel2.wav I get no recordings. Did I miss something with the configuration or what are my options to record all 8 channels via arecord. I've no experience with jackd. Is it an option to install jackd and record the line ins via jackd?

• How to talk a client out of a Flash website?

  - by bunglestink

  I have recently been doing a bunch of web side projects through word of mouth recommendations only. Although I am much more a of a programmer than a designer by any means, my design skills are not terrible, and do not hate dealing with UI like many programmers. As a result, I find myself lured into a bunch of side projects where aside from a minimal back end for content administration, most of the programming is on front end interfaces (read javascript/css). By far the biggest frustration I have had is convincing clients that they do not want Flash. Aside the fact that I really do not enjoy Flash "development", there are many practical reasons why Flash is not desirable (lack of compatibility across devices, decreased client accessibility, plug-in requirements, increased development time, etc.). Instead of just flat out telling the clients "I will not build you a flash website", I would much rather use tactics to convince/explain to them that this is not what they actually want, ie: meet their requirements any better than standard html/css/js and distract users from their content. What kind of first hand experience do others have with this? How do you explain to someone that javascript/css/AJAX is usually a better option for most websites? Why do people want to use Flash so bad to begin with? This question pertains to clients who do not have any technical reasons for wanting flash, but just want it because they think it makes pretty websites.

• How can I hard reset a USB device?

  - by Cory

  I have a USB device (a modem) that is really finicky. Sometimes it works fine, but other times it refuses to connect. The only solution I have found to fix it once it gets into a bad state is to physically unplug the device and plug it back in. However, I don't always have physical access to the machine it is plugged in on, so I'm looking for a way to do this through the command line. This post suggests running: sudo modprobe -w -r usb_storage; sudo modprobe usb_storage However I get an "unknown option -w" output. This slightly modified command: sudo modprobe -r usb_storage Fails with the message FATAL: Module usb_storage is in use. If I try to kill -9 the processes marked [usb-storage] before running they refuse to die (I think because they are deeply tied to the kernel). Anyone know of a way to do this? NOTE: I cross-posted this on superuser.com as I didn't know which was more appropriate. I will delete and/or link whichever one is answered first.

• Netbook performs hard shutdown without warning on low battery power

  - by Steve Kroon

  My Asus EEE netbook performs a hard shutdown when it reaches low battery power, without giving any warning - i.e. the power just goes off, without any shutdown process. I can't find anything in the syslog, and no error messages are printed before it happens. I've had this problem on previous (K)Ubuntu versions, and hoped updating to Ubuntu Precise would help resolve the issue, but it hasn't. The option in the Power application for "when power is critically low" is currently blank - the only options are a (grayed-out) hibernate and "Power off". I have re-installed indicator-power to no effect. The time remaining reported by acpi is unstable, as is the time remaining reported by gnome-power-statistics. (For example, running acpi twice in succession, I got 2h16min, and then 3h21min remaining. These sorts of jumps in the remaining time are also in the gnome-power-statistics graphs.) It might be possible to write a script to give me advance warning (as per @RanRag's comment below), but I would prefer to isolate why I don't get a critical battery notification from the system before this happens, so that I can take action as appropriate (suspend/shutdown/plug in power) when I get a notification.

• Ubuntu 12.10 boots to purple or black screen but intermittently boots fine

  - by Nic

  I have a fresh install of Ubuntu 12.10 64bit dual booting with Win7 64bit. Windows boots fine every time. When I choose Ubuntu from Grub2 menu it will sometimes boot just fine. Most of the times though it gets stuck at a purple screen with nothing happening and no keys or key combinations working. Other times instead of the purple screen I get a black screen with a flashing cursor at the top. Nothing happens. I need to hold down the power button to restart and after a couple times of trying it will eventually boot into Ubuntu. Once that happens everything runs without any problems. I have tried different approaches to fix the problem but to no avail. I tried removing "quiet splash", used no splash, and nomodeset What I got from this was seeing all the text of the boot process but more often than not the process gets stuck right after recognizing all the USB ports and devices. If it gets stuck nothing happens (except when i plug in a usb device: it still recognizes it with a new line of text) In the case when the boot process works, after it lists the usb devices it tells me something like: recovery of read-only filesystem necessary. (its the filesystem that ubuntu runs on) then it does the recovery and i get: recovery complete. after that Ubuntu will boot properly and I get to see the login screen. I have no idea what to do to fix that problem. I have to reboot 3 to 5 times everytime I want to get into Ubuntu and I feel like I'm breaking my new Laptop. (its a lenovo ideapad z580 btw. i5 processor and nvidia gtx640 graphics card) I hope someone can help me. Thanks. Edit: i just got a "failed to enable AA error" message when waking it up from suspend. I don't know if that helps or has anything to do with the boot probs.

• Using the OAM Mobile & Social SDK to secure native mobile apps - Part 2 : OAM Mobile & Social Server configuration

  - by kanishkmahajan

  Objective  In the second part of this blog post I'll now cover configuration of OAM to secure our sample native apps developed using the iOS SDK. First, here are some key server side concepts: Application Profiles: An application profile is a logical representation of your application within OAM server. It could be a web (html/javascript) or native (iOS or Android) application. Applications may have different requirements for AuthN/AuthZ, and therefore each application that interacts with OAM Mobile & Social REST services must be uniquely defined. Service Providers: Service providers represent the back end services that are accessed by applications. With OAM Mobile & Social these services are in the areas of authentication, authorization and user profile access. A Service Provider then defines a type or class of service for authentication, authorization or user profiles. For example, the JWTAuthentication provider performs authentication and returns JWT (JSON Web Tokens) to the application. In contrast, the OAMAuthentication also provides authentication but uses OAM SSO tokens Service Profiles:  A Service Profile is a logical envelope that defines a service endpoint URL for a service provider for the OAM Mobile & Social Service. You can create multiple service profiles for a service provider to define token capabilities and service endpoints. Each service provider instance requires atleast one corresponding service profile.The  OAM Mobile & Social Service includes a pre-configured service profile for each pre-configured service provider. Service Domains: Service domains bind together application profiles and service profiles with an optional security handler. So now let's configure the OAM server. Additional details are in the OAM Documentation and this post simply provides an outline of configuration tasks required to configure OAM for securing native apps.  Configuration  Create The Application Profile Log on to the Oracle Access Management console and from System Configuration -> Mobile and Social -> Mobile Services, select "Create" under Application Profiles. You would do this  step twice - once for each of the native apps - AvitekInventory and AvitekScheduler. Enter the parameters for the new Application profile: Name:  The application name. In this example we use 'InventoryApp' for the AvitekInventory app and 'SchedulerApp' for the AvitekScheduler app. The application name configured here must match the application name in the settings for the deployed iOS application. BaseSecret: Enter a password here. This does not need to match any existing password. It is used as an encryption key between the client and the OAM server.  Mobile Configuration: Enable this checkbox for any mobile applications. This enables the SDK to collect and send Mobile specific attributes to the OAM server.  Webview: Controls the type of browser that the iOS application will use. The embedded browser (default) will render the browser within the application. External will use the system standalone browser. External can sometimes be preferable for debugging URLScheme: The URL scheme associated with the iOS apps that is also used as a custom URL scheme to register O/S handlers that will take control when OAM transfers control to device. For the AvitekInventory and the AvitekScheduler apps I used osa:// and client:// respectively. You set this scheme in Xcode while developing your iOS Apps under Info->URL Types.  Bundle Identifier : The fully qualified name of your iOS application. You typically set this when you create a new Xcode project or under General->Identity in Xcode. For the AvitekInventory and AvitekScheduler apps these were com.us.oracle.AvitekInventory and com.us.oracle.AvitekScheduler respectively.  Create The Service Domain Select create under Service domains. Create a name for your domain (AvitekDomain is what I've used). The name configured must match the service domain set in the iOS application settings. Under "Application Profile Selection" click the browse button. Choose the application profiles that you created in the previous step one by one. Set the InventoryApp as the SSO agent (with an automatic priority of 1) and the SchedulerApp as the SSO client. This associates these applications with this service domain and configures them in a 'circle of trust'.  Advance to the next page of the wizard to configure the services for this domain. For this example we will use the following services:  Authentication:   This will use the JWT (JSON Web Token) format authentication provider. The iOS application upon successful authentication will receive a signed JWT token from OAM Mobile & Social service. This token will be used in subsequent calls to OAM. Use 'MobileOAMAuthentication' here. Authorization:  The authorization provider. The SDK makes calls to this provider endpoint to obtain authorization decisions on resource requests. Use 'OAMAuthorization' here. User Profile Service:  This is the service that provides user profile services (attribute lookup, attribute modification). It can be any directory configured as a data source in OAM.  And that's it! We're done configuring our native apps. In the next section, let's look at some additional features that were mentioned in the earlier post that are automated by the SDK for the app developer i.e. these are areas that require no additional coding by the app developer when developing with the SDK as they only require server side configuration: Additional Configuration  Offline Authentication Select this option in the service domain configuration to allow users to log in and authenticate to the application locally. Clear the box to block users from authenticating locally. Strong Authentication By simply selecting the OAAMSecurityHandlerPlugin while configuring mobile related Service Domains, the OAM Mobile&Social service allows sophisticated device and client application registration logic as well as the advanced risk and fraud analysis logic found in OAAM to be applied to mobile authentication. Let's look at some scenarios where the OAAMSecurityHandlerPlugin gets used. First, when we configure OAM and OAAM to integrate together using the TAP scheme, then that integration kicks off by selecting the OAAMSecurityHandlerPlugin in the mobile service domain. This is how the mobile device is now prompted for KBA,OTP etc depending on the TAP scheme integration and the OAM users registered in the OAAM database. Second, when we configured the service domain, there were claim attributes there that are already pre-configured in OAM Mobile&Social service and we simply accepted the default values- these are the set of attributes that will be fetched from the device and passed to the server during registration/authentication as device profile attributes. When a mobile application requests a token through the Mobile Client SDK, the SDK logic will send the Device Profile attributes as a part of an HTTP request. This set of Device Profile attributes enhances security by creating an audit trail for devices that assists device identification. When the OAAM Security Plug-in is used, a particular combination of Device Profile attribute values is treated as a device finger print, known as the Digital Finger Print in the OAAM Administration Console. Each finger print is assigned a unique fingerprint number. Each OAAM session is associated with a finger print and the finger print makes it possible to log (and audit) the devices that are performing authentication and token acquisition. Finally, if the jail broken option is selected while configuring an application profile, the SDK detects a device is jail broken based on configured policy and if the OAAM handler is configured the plug-in can allow or block access to client device depending on the OAAM policy as well as detect blacklisted, lost or stolen devices and send a wipeout command that deletes all the mobile &social relevant data and blocks the device from future access. 1024x768 Social Logins Finally, let's complete this post by adding configuration to configure social logins for mobile applications. Although the Avitek sample apps do not demonstrate social logins this would be an ideal exercise for you based on the sample code provided in the earlier post. I'll cover the server side configuration here (with Facebook as an example) and you can retrofit the code to accommodate social logins by following the steps outlined in "Invoking Authentication Services" and add code in LoginViewController and maybe create a new delegate - AvitekRPDelegate based on the description in the previous post. So, here all you will need to do is configure an application profile for social login, configure a new service domain that uses the social login application profile, register the app on Facebook and finally configure the Facebook OAuth provider in OAM with those settings. Navigate to Mobile and Social, click on "Internet Identity Services" and create a new application profile. Here are the relevant parameters for the new application profile (-also we're not registering the social user in OAM with this configuration below, however that is a key feature as well): Name:  The application name. This must match the name of the of mobile application profile created for your application under Mobile Services. We used InventoryApp for this example. SharedSecret: Enter a password here. This does not need to match any existing password. It is used as an encryption key between the client and the OAM Mobile and Social service.  Mobile Application Return URL: After the Relying Party (social) login, the OAM Mobile & Social service will redirect to the iOS application using this URI. This is defined under Info->URL type and we used 'osa', so we define this here as 'osa://' Login Type: Choose to allow only internet identity authentication for this exercise. Authentication Service Endpoint : Make sure that /internetidentityauthentication is selected. Login to http://developers.facebook.com using your Facebook account and click on Apps and register the app as InventoryApp. Note that the consumer key and API secret gets generated automatically by the Facebook OAuth server. Navigate back to OAM and under Mobile and Social, click on "Internet Identity Services" and edit the Facebook OAuth Provider. Add the consumer key and API secret from the Facebook developers site to the Facebook OAuth Provider: Navigate to Mobile Services. Click on New to create a new service domain. In this example we call the domain "AvitekDomainRP". The type should be 'Mobile Application' and the application credential type 'User Token'. Add the application "InventoryApp" to the domain. Advance the next page of the wizard. Select the  default service profiles but ensure that the Authentication Service is set to 'InternetIdentityAuthentication'. Finish the creation of the service domain.

• CodeGolf : Find the Unique Paths

  - by st0le

  Here's a pretty simple idea, in this pastebin I've posted some pair of numbers. These represent Nodes of a unidirected connected graph. The input to stdin will be of the form, (they'll be numbers, i'll be using an example here) c d q r a b d e p q so x y means x is connected to y (not viceversa) There are 2 paths in that example. a->b->c->d->e and p->q->r. You need to print all the unique paths from that graph The output should be of the format a->b->c->d->e p->q->r Notes You can assume the numbers are chosen such that one path doesn't intersect the other (one node belongs to one path) The pairs are in random order. They are more than 1 paths, they can be of different lengths. All numbers are less than 1000. If you need more details, please leave a comment. I'll amend as required. Shameless-Plug For those who enjoy Codegolf, please Commit at Area51 for its very own site:) (for those who don't enjoy it, please support it as well, so we'll stay out of your way...)

  Agile software development relies heavily on a work item type called user stories. For example, you have a backlog full of user stories and you can select a few of them to work on during the next sprint. But where and how do you find user stories to put into the backlog? There is a popular technique for doing that called story mapping. Jeff Patton invented it and here is the definitive guide on how to do it. The question is, what electronic tools are out there that support Patton's story-mapping technique? I've done a bit of research, found Pivotal and Rally plug-ins (but I'm not a customer of either) and I'm currently experimenting with SilverStories. What other tools are out there? What have you used? What do you (not) recommend? Why? UPDATE: Some people who wrote comments seem to lean towards an answer that applying this technique is simply impossible with an electronic tool and we should just accept that. Can't someone write it up as an answer?

• External monitor is blank if I boot with the monitor plugged in

  - by Ronald

  Ubuntu 12.04 has problem with Intel GM45 Chipset, featuring the the Mobile Intel® Graphics Media Accelerator (GMA) 4500MHD I have a COMPAQ Presario CQ70 laptop with an Intel GM45 chipset that features the Mobile Intel® Graphics Media Accelerator (GMA) 4500MHD. I was using the second HDMI video port to drive both a projector or a second monitor. Everything was working fine under Ubuntu 8.04, 9.04, 10.04 and 11.04, however, when I upgraded to 12.04 the second monitor stopped working. What I mean when I say stopped working is: boot with monitor plugged in. Blank screen! Power off, unplug monitor and power on everything works. Plug in monitor (only mode that works in Mirror mode) two monitors that look same. Close laptop lid. screen goes blank only option for useful system is power off and unplug monitor. If I attempt to Adjust the monitor to maximum resolution that the monitor will handle and turn off mirror mode nothing can be moved onto that screen. This all worked fine with earlier versions of Ubuntu, is there a notes about the changes to the graphics management system in 12.04, like there is for the resolver change?

• Booting sequence. Ubuntu 12.04 installation and cohabitation with former OSes

  - by Stephane Rolland

  I am on the brink of installing Ubuntu 12.04 Precise Pengolin on the first primary partition of my hard-drive. (A day in History for me since I had always kept a MS windows at this first place). But I have some fears: This is my last computer available (In the past I used to have 2 or even 3 machines so I could always un/plug HDs for recovery operations and rescue) The current booting sequence is not straight forard. So as to explain the boot sequence let me briefly sum-up the history of this laptop computer. It was a dedicated Windows Vista computer. 1st and only Primary partition. Then I added Windows 7 (on the 2nd primary partition) letting the Windows Vista Boot Loader manage the boot sequence. Then I added Ubuntu 10.04 Lucid Lynx on the 1st sub-partition of the Extended Partitionm asking Grub to be the boot loader. But when I ask Grub to launch windows it launches the Vista BootLoader that manages the choice betzeen Vista and 7. So in theory Grub is on the MasterBootRecord - though I understand where the Vista BootLoader remains. Now, I will no longer use the Ubuntu 10.04 ( on extended partition) and also the Windows vista (on the first primary partition). I will install Ubuntu 12.04 on the First Primary, asking it to install a new bootloader. I want to keep the Windows 7 that is already on the Second Primary partition. And I want it to be loaded by the Ubuntu Boot loader(I don4t knoz zhich is included in this version)... And I am afraid the last point will not work.

• how do I make my Dualshock 3 gamepad work in Ubuntu 14.04?

  - by user290527

  When my desktop computer was running Ubuntu 12.04, my PS3 controllers would work with USB. I didn't need to do any special setup. I could just plug it in before I start SuperTuxKart and it would recognize it. I can also do this on my laptop (still running 12.04). Since I gave my desktop a fresh install of Ubuntu 14.04, the controller would never work. I have played with some installed software that I found when looking for information. Here is what I get with xboxdrv: liam@Liam-CustomDesktop:~$ sudo xboxdrv --detach-kernel-driver xboxdrv 0.8.5 - http://pingus.seul.org/~grumbel/xboxdrv/ Copyright © 2008-2011 Ingo Ruhnke <[email protected]> Licensed under GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> This program comes with ABSOLUTELY NO WARRANTY.

Controller: PLAYSTATION(R)3 Controller Vendor/Product: 054c:0268 USB Path: 003:012 Controller Type: Playstation 3 USB Your Xbox/Xbox360 controller should now be available as: /dev/input/js0 /dev/input/event16 Press Ctrl-c to quit, use '--silent' to suppress the event output So the existence of this controller is acknowledged at on my computer. But it never works for input. In my old installation, I didn't even need to get software like xboxdrv for it to work. I have never tried bluetooth on either computer, but I don't think I even have that on my desktop. So now, how do I make my gamepad work in Ubuntu 14.04?

• SAP or Navision? Career Path

  - by codebased

  This could be tricky to ask; I may or may not ask this question here but I thought to give it a try. I've been in Software Industry since 2002 and now it has been a time that I'm at Senior level where I normally code, lead and define the architect; giving technical solutions to the management is one of my asset that I've earned during my services. Now it is the time to define the road map for the future, $$$. I am not in favor of Project Management roles. I've been thinking of going through the ERP and my current company does provide me an option to go for Navision/ Microsoft Dynamics. They are currently on 4.0 but they are planning to move for 2009 and also to build one of their own plug-in. Indeed the option is good because Microsoft is trying to accomplish the market for Dynamics products. However, they have less success in Australia. Now, Another option is with SAP where person can go with 200 K $ a year. Where as I'd doubt that if the same kind of growth, financial, is available for Microsoft geek. What is your opinion on Navision or SAP? If I try to completely move to SAP it could be bit challenging as market will consider me a fresher. However the return is quite good. Where in case of Microsoft, I think technology changes so fast that there is a less chance to grow in, within, the same experience; in other word, if any new framework comes in .net then market look for that person who knows this new framework and not .net But in case of SAP, where the base remain same and chances are to grab more money from the market. What would you do if you were me? In stackoverflow - Navision questions are 20+ where in SAP 200+///?? :-)

• UEFI Boot Failure - Hang after Printing USB Information

  - by James

  I'm experiencing a really weird boot problem. With both 12.10 and 12.04LTS, the vast majority of kernels (and initrds) that I've tried boot, but hang immediately after printing out information about USB devices. This isn't exactly a full "hang" so to speak, as if I plug in a flash drive, I see information and a /dev/sd* entry printed to the screen. Post/pre-init scripts are not run, there is no handoff, nor busybox or VT prompt. Virtual terminals can't be changed (with Ctrl-Alt-Fx). For what I can see, init may have not been executed yet. With certain kernel and OS combinations however, (specifically 3.2.0-29), I get a full boot and am able to use the OS as if there is no problem. After 3.2.0-29, I've been hard pressed to find a kernel that works. Any idea what's happening or how to fix this? Or even a road to take? I've exhausted the first five pages of Google for every search term I can think of. This is a Lenovo Z580 (i5-3210M) with Phoenix SecureCore Tiano firmware, if that helps any.

• Automatically create bug resolution task using the TFS 2010 API

  - by Bob Hardister

  My customer requires bug resolution to be approved and tracked.  To minimize the overhead for developers I implemented a TFS 2010 server-side plug-in to automatically create a child resolution task for the bug when the “CCB” field is set to approved. The CCB field is a custom field.  I also added the story points field to the bug WIT for sizing purposes. Redundant tasks will not be created unless the bug title is changed or the prior task is closed. The program writes an audit trail to a log file visible in the TFS Admin Console Log view. Here’s the code. BugAutoTask.cs /* SPECIFICATION * When the CCB field on the bug is set to approved, create a child task where the task: * name = Resolve bug [ID] - [Title of bug] * assigned to = same as assigned to field on the bug * same area path * same iteration path * activity = Bug Resolution * original estimate = bug points * * The source code is used to build a dll (Ows.TeamFoundation.BugAutoTaskCreation.PlugIns.dll), * which needs to be copied to * C:\Program Files\Microsoft Team Foundation Server 2010\Application Tier\Web Services\bin\Plugins * on ALL TFS application-tier servers. * * Author: Bob Hardister. */ using System; using System.Collections.Generic; using System.IO; using System.Xml; using System.Text; using System.Diagnostics; using System.Linq; using Microsoft.TeamFoundation.Common; using Microsoft.TeamFoundation.Framework.Server; using Microsoft.TeamFoundation.WorkItemTracking.Client; using Microsoft.TeamFoundation.WorkItemTracking.Server; using Microsoft.TeamFoundation.Client; using System.Collections; namespace BugAutoTaskCreation { public class BugAutoTask : ISubscriber { public EventNotificationStatus ProcessEvent(TeamFoundationRequestContext requestContext, NotificationType notificationType, object notificationEventArgs, out int statusCode, out string statusMessage, out ExceptionPropertyCollection properties) { statusCode = 0; properties = null; statusMessage = String.Empty; // Error message for for tracing last code executed and optional fields string lastStep = "No field values found or set "; try { if ((notificationType == NotificationType.Notification) && (notificationEventArgs.GetType() == typeof(WorkItemChangedEvent))) { WorkItemChangedEvent workItemChange = (WorkItemChangedEvent)notificationEventArgs; // see ConnectToTFS() method below to select which TFS instance/collection // to connect to TfsTeamProjectCollection tfs = ConnectToTFS(); WorkItemStore wiStore = tfs.GetService<WorkItemStore>(); lastStep = lastStep + ": connection to TFS successful "; // Get the work item that was just changed by the user.

• Message Driven Bean JMS integration

  - by Anthony Shorten

  In Oracle Utilities Application Framework V4.1 and above the product introduced the concept of real time JMS integration within the Framework for interfacing. Customer familiar with older versions of the Framework will recall that we used a component called the Multi-purpose Listener (MPL) which was a very light service bus for calling interface channels (including JMS). The MPL is not supplied with all products and customers prefer to use Oracle SOA Suite and native methods rather then MPL. In Oracle Utilities Application Framework V4.1 (and for Oracle Utilities Application Framework V2.2 via Patches 9454971, 9256359, 9672027 and 9838219) we introduced real time JMS integration natively for outbound JMS integration and using Message Driven Beans (MDB) for incoming integration. The outbound integration has not changed a lot between releases where you create an Outbound Message Type to indicate the record types to send out, create a JMS sender (though now you use the Real Time Sender) and then create an External System definition to complete the configuration. When an outbound message appears in the table of the type and external system configured (via a business event such as an algorithm or plug-in script) the Oracle Utilities Application Framework will place the message on the configured Queue linked to the JMS Sender. The inbound integration has changed. In the past you created XAI Receivers and specified configuration about what types of transactions to process. This is now all configuration file driven. The configuration files for the Business Application Server (ejb-jar.xml and weblogic-ejb-jar.xml) define Message Driven Beans and the queues to monitor. When a message appears on the queue, the MDB processes it through our web services interface. Configuration of the MDB can be native (via editing the configuration files) or through the new user exit capabilities (which is aimed at maintaining custom configuration across upgrades). The latter is better as you build fragments of configuration to make it easier to maintain. In the next few weeks a number of new whitepaper will be released to illustrate the features of the Oracle WebLogic JMS and Oracle SOA Suite integration capabilities.

• How to use the Raring/Saucy netboot installer to install Precise?

  - by mikepurvis

  We have a Haswell motherboard with onboard ethernet controllers which are not supported in the Precise (3.2) kernel. However, we're using netboot installation, and we'd really like to stick with the LTS version. Once the Precise install is completed, we can install the linux-generic-lts-saucy package, which gets us the ethernet hardware support which is ultimately required. So, our options are: Plug in a USB-Ethernet (or even wifi) dongle, perform the install that way. Modify the Precise installer to somehow include the required driver (a udeb, or some early_command invocation?) Modify the Raring installer (3.8 kernel, which supports the device) to instead install Precise. If it's possible the third option seems like the simplest and most logical to me. Now, we are already using the precise-updates installer (Aug 2013), as opposed to the original April 2012 installer. However, the precise-updates installer still appears to use the 3.2 kernel. I'm already comfortable with preseeding and modifying the netboot initrd. So my question is, can I somehow modify the Raring/Saucy netboot initrd to instead install Precise? Thanks.
