• How do I roll back to the shipped version of Thunderbird?

  - by kallakafar

  I was using thunderbird v15.0 on ubuntu 12.04 LTS till now, and have the lightning extension installed to manage calendar within thunderbird application. everything was working fine until i decided to update thunderbird to the latest version 16.0 from ubuntu repository. installation was successful, and the profile everything was taken care of perfectly, except that now lightning is not working - it is disabled as lightning v1.7 is NOT compatible with latest thunderbird v16 yet. As a result i am at loss with all my scheduling. now, i would like to go back to thunderbird v15 so that i can use lightning. ubuntu repository only gives TB v16 now. on mozilla site, they are still giving v15 for linux, so i downloaded the tarball and uncompressed using command line. now i have a folder called thunderbird. there are no readme/ configuration files. there are following 'executable files' inside this folder: crashreporter, mozilla-remote-client, plugin-container, thunderbird and thunderbird-bin. i tried invoking thunderbird and thunderbird-bin from command line using sudo, still nothing is opening up. i have execute permissions for this folder contents. i m quite new to linux. please let me know why i m not able to launch thunderbird. did i install it incorrectly? please let me know if i can get a .deb package for TB v15.

• Illegal characters for SharePoint 2010 Content Type name

  - by Kelly Jones

  Quick tip: you can’t include a backslash in the name of the SharePoint 2010 Content Type.  In fact, there are several illegal characters:  \  / : * ? " # % < > { } | ~ & , two consecutive periods (..), or special characters such as a tab. What, you didn’t know that after entering one of these characters in the name?  Is it because you saw this screen: Oh, that’s right….you need to turn off custom errors in the layouts folder…See this blog post for details and you’ll also need to turn off for the web application. Once you do that, you’ll see this: I wonder why the SharePoint team just doesn’t let the user know that the content type name contains illegal characters before the user hits the create button. Here’s a copy of the complete error (for the search engines): Server Error in '/' Application. -------------------------------------------------------------------------------- The content type name 'asdfadsf\asdfasf' cannot contain: \  / : * ?

• Oracle Social Network -The Social Glue for Enterprise Applications

  - by kellsey.ruppel

  by Peter Reiser  - Social Business Evangelist, Oracle WebCenter  Tom Petrocelli of Enterprise Strategy Group published a report recently, “Oracle Social Network: The Social Glue for Enterprise Applications”, on Oracle Social Network (OSN) and how traditional social products create social silos whereas OSN is the “social glue” for enterprise applications.  This report supports the point of Oracle’s Social Business Strategy to seamless integrate social capabilities into the main business processes. Quote from report: “Oracle has adopted the correct approach to creating a social layer and socially enabled applications. Oracle Social Network is not simply another enterprise social network product; it is a complete social layer for the enterprise application stack. This approach will serve Oracle users well in the future.” OSN allow to capture the related Conversations of a business process right where it’s happens – within the respective Business application.  Fusion CRM is an excellent example for this approach. Quote from report: “Oracle’s new software, Oracle Social Network, is an example of a solution to the silo problem. While Oracle fields a typical enterprise social network application with microblogging, file sharing, shared documents or wikis, and activity streams, the front-end application is only a small part of what Oracle Social Network does. Instead, Oracle Social Network is a platform that provides social features as a service to other enterprise applications. In effect, Oracle Social Network socially enables all of Oracle’s enterprise applications—all enterprise applications really—with not only the same features, but also the same conversations. As a result, the social conversations act as a conduit for inter-application communication and collaboration.” Source: ESG Research Report, Oracle Social Network: The Social Glue for Enterprise Applications, August 2012.

• SYS2 Scripts Updated – Scripts to monitor database backup, database space usage and memory grants now available

  - by Davide Mauri

  I’ve just released three new scripts of my “sys2” script collection that can be found on CodePlex: Project Page: http://sys2dmvs.codeplex.com/ Source Code Download: http://sys2dmvs.codeplex.com/SourceControl/changeset/view/57732 The three new scripts are the following sys2.database_backup_info.sql sys2.query_memory_grants.sql sys2.stp_get_databases_space_used_info.sql Here’s some more details: database_backup_info This script has been made to quickly check if and when backup was done. It will report the last full, differential and log backup date and time for each database. Along with these information you’ll also get some additional metadata that shows if a database is a read-only database and its recovery model: By default it will check only the last seven days, but you can change this value just specifying how many days back you want to check. To analyze the last seven days, and list only the database with FULL recovery model without a log backup select * from sys2.databases_backup_info(default) where recovery_model = 3 and log_backup = 0 To analyze the last fifteen days, and list only the database with FULL recovery model with a differential backup select * from sys2.databases_backup_info(15) where recovery_model = 3 and diff_backup = 1 I just love this script, I use it every time I need to check that backups are not too old and that t-log backup are correctly scheduled. query_memory_grants This is just a wrapper around sys.dm_exec_query_memory_grants that enriches the default result set with the text of the query for which memory has been granted or is waiting for a memory grant and, optionally, its execution plan stp_get_databases_space_used_info This is a stored procedure that list all the available databases and for each one the overall size, the used space within that size, the maximum size it may reach and the auto grow options. This is another script I use every day in order to be able to monitor, track and forecast database space usage. As usual feedbacks and suggestions are more than welcome!

• Five Bucks says you’ll Bookmark this Site: jsFiddle.net

  - by SGWellens

  In my never-ending wandering of technical web sites, I've been encountering links to jsFiddle.net more and more. Why? Because it is an incredibly useful site: It is a great 'sandbox' to play in. You can test, modify and retest HTML, CSS, and JavaScript code. It is a great way to communicate technical issues and share code samples. There are four screen areas: Three inputs* and one output: The three inputs are: HTML CSS JavaScript The output is: The rendered result Here's a cropped screen shot: What am I thinking? Here's the actual page: Demo *There are other inputs. You can select the level of HTML you want to run against (HTM5, HTML4.01 Strict, etc). You can add various versions of JavaScript libraries (jQuery, MooTools, YUI, etc.). Many other options are available. If I wanted to share this code with someone manually, they would have to copy and paste three separate code chunks into their development environment. And maybe load some external libraries. Not many people are willing to make such an effort. Instead, with jsFiddler, they can just go to the link and click Run. Awesome. I hope someone finds this useful (and I was kidding about the five bucks). Steve Wellens CodeProject

• AspNetCompatibility in WCF Services &ndash; easy to trip up

  - by Rick Strahl

  This isn’t the first time I’ve hit this particular wall: I’m creating a WCF REST service for AJAX callbacks and using the WebScriptServiceHostFactory host factory in the service: <%@ ServiceHost Language="C#" Service="WcfAjax.BasicWcfService" CodeBehind="BasicWcfService.cs" Factory="System.ServiceModel.Activation.WebScriptServiceHostFactory" %>   to avoid all configuration. Because of the Factory that creates the ASP.NET Ajax compatible format via the custom factory implementation I can then remove all of the configuration settings that typically get dumped into the web.config file. However, I do want ASP.NET compatibility so I still leave in: <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> </system.serviceModel> in the web.config file. This option allows you access to the HttpContext.Current object to effectively give you access to most of the standard ASP.NET request and response features. This is not recommended as a primary practice but it can be useful in some scenarios and in backwards compatibility scenerios with ASP.NET AJAX Web Services. Now, here’s where things get funky. Assuming you have the setting in web.config, If you now declare a service like this: [ServiceContract(Namespace = "DevConnections")] #if DEBUG [ServiceBehavior(IncludeExceptionDetailInFaults = true)] #endif public class BasicWcfService (or by using an interface that defines the service contract) you’ll find that the service will not work when an AJAX call is made against it. You’ll get a 500 error and a System.ServiceModel.ServiceActivationException System error. Worse even with the IncludeExceptionDetailInFaults enabled you get absolutely no indication from WCF what the problem is. So what’s the problem?  The issue is that once you specify aspNetCompatibilityEnabled=”true” in the configuration you *have to* specify the AspNetCompatibilityRequirements attribute and one of the modes that enables or at least allows for it. You need either Required or Allow: [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)] without it the service will simply fail without further warning. It will also fail if you set the attribute value to NotAllowed. The following also causes the service to fail as above: [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.NotAllowed)] This is not totally unreasonable but it’s a difficult issue to debug especially since the configuration setting is global – if you have more than one service and one requires traditional ASP.NET access and one doesn’t then both must have the attribute specified. This is one reason why you’d want to avoid using this functionality unless absolutely necessary. WCF REST provides some basic access to some of the HTTP features after all, although what’s there is severely limited. I also wish that ServiceActivation errors would provide more error information. Getting an Activation error without further info on what actually is wrong is pretty worthless especially when it is a technicality like a mismatched configuration/attribute setting like this.© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET  WCF  AJAX

• Initially Unselected DropDownList

  - by Ricardo Peres

  One of the most (IMHO) things with DropDownList is its inability to show an unselected value at load time, which is something that HTML does permit. I decided to change the DropDownList to add this behavior. All was needed was some JavaScript and reflection. See the result for yourself: public class CustomDropDownList : DropDownList { public CustomDropDownList() { this.InitiallyUnselected = true; } [DefaultValue(true)] public Boolean InitiallyUnselected { get; set; } protected override void OnInit(EventArgs e) { this.Page.RegisterRequiresControlState(this); this.Page.PreRenderComplete += this.OnPreRenderComplete; base.OnInit(e); } protected virtual void OnPreRenderComplete(Object sender, EventArgs args) { FieldInfo cachedSelectedValue = typeof(ListControl).GetField("cachedSelectedValue", BindingFlags.NonPublic | BindingFlags.Instance); if (String.IsNullOrEmpty(cachedSelectedValue.GetValue(this) as String) == true) { if (this.InitiallyUnselected == true) { if ((ScriptManager.GetCurrent(this.Page) != null) && (ScriptManager.GetCurrent(this.Page).IsInAsyncPostBack == true)) { ScriptManager.RegisterStartupScript(this, this.GetType(), "unselect" + this.ClientID, "$get('" + this.ClientID + "').selectedIndex = -1;", true); } else { this.Page.ClientScript.RegisterStartupScript(this.GetType(), "unselect" + this.ClientID, "$get('" + this.ClientID + "').selectedIndex = -1;", true); } } } } } SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/2.0.320/scripts/clipboard.swf'; SyntaxHighlighter.brushes.CSharp.aliases = ['c#', 'c-sharp', 'csharp']; SyntaxHighlighter.all();

• VNC client not working -- Not able to see the changes happening on the other side

  - by javanoob

  Here is the Problem: I have two computers connected in the same LAN. I am trying to access one computer from another using Remote Desktop Viewer, I am able to see the remote desktop. But when i click on any thing or perform any action, I dont see the result but the action is performed on the remote desktop..But it is not refreshed on the remote desktop screen.. For Ex: 1) Opened Remote Desktop viewer 2) Connected to the other computer which has yahoo home page opened 3) Clicked on the close button of the web page 4) Action is performed on the other computer (Yahoo page is closed). 5) On Remote Desktop screen i still see the Yahoo home page 6) Whatever action i perform on remote desktop screen i see the same screen(In this case yahoo home page) Bottom line: Whatever screen i see on the start up of Remote Desktop viewer that is not getting refreshed. So the thing is though i am able to perform actions on remote desktop, the screen is not refreshing.. How do i solve this? I hope i made my point clear.. NOTE: I am connecting to Ubuntu 9.04 machine from Ubuntu 10.04LTS.. I am really not sure if that makes any difference.

• How to perform feature upgrade in SharePoint2010 part2

  - by ybbest

  In my last post, I showed you how to perform feature upgrade and upgrade my feature from 0.0.0.0 to 1.0.0.1. In this post, I’d like to continue on this topic and upgrade the feature again. For the first version of my solution, I deploy a document library with a custom document set content type and then upgrade the solution so I index the application number column. Now , I will create a new version of the solution so that it will remove the threshold of the list. You can download the solution here. Once you extract your solution, the first version is in the original folder. In order to deploy the original solution, you need to run the sitecreation.ps1 in the script folder. The version 1.1 will be in the Upgrade folder and version 1.2 will be in the Upgrade2 folder. You need to make the following changes to the existing solution. 1. Modify the ApplicationLibrary.Template.xml as highlighted below: 2. Adding the following code into the feature event receiver. </pre> public override void FeatureUpgrading(SPFeatureReceiverProperties properties, string upgradeActionName, System.Collections.Generic.IDictionary<string, string> parameters) { base.FeatureUpgrading(properties, upgradeActionName, parameters); SPWeb web = GetFeatureWeb(properties); SPList applicationLibrary = web.Lists.TryGetList(ApplicationLibraryNamesConstant.ApplicationLibraryName); switch (upgradeActionName) { case "IndexApplicationNumber": if (applicationLibrary != null) { SPField queueField = applicationLibrary.Fields["ApplicationNumber"]; queueField.Indexed = true; queueField.Update(); } break; case "RemoveListThreshold": applicationLibrary.EnableThrottling = false; applicationLibrary.Update(); break; } } <pre> 3. Package your solution and run the feature upgrade PowerShell script. $wspFolder ="v1.2" $scriptPath=Split-Path $myInvocation.MyCommand.Path $siteUrl = "http://ybbest" $featureToCheckGuid="1b9d84cd-227d-45f1-92d4-a43008aa8fe7" $requiredFeatureVersion="1.0.0.1" $siteUrlOfFeatureToBeChecked="http://ybbest" AppendLog "Starting Solution UpgradeSolutionAndFeatures.ps1" Magenta & "$scriptPath\UpgradeSolutionAndFeatures.ps1" $siteUrl $wspFolder $featureToCheckGuid $requiredFeatureVersion $siteUrlOfFeatureToBeChecked Write-Host AppendLog "All features updated" "Green" References: Feature upgrade.

• The Minimalist Approach to Content Governance - Retire Phase

  - by Kellsey Ruppel

   Originally posted by John Brunswick. Good news - the Retire Phase is actually more fun than the Manage Phase. During the Retire Phase our content management team should not have to track down content creators if the Request Phase of this process was completed successfully. The ownership meta data, success criteria and time stamp that was applied to the original content submission will help to manage content at the end of the content life cycle. The Retire Phase will provide the opportunity for us to prune irrelevant content items through archiving or deletion, keeping the content system clear of irrelevant information, streamlining users ability to browse and search for content.   1. Act on Metrics Established during the Request Phase Why - Some information is only relevant for a given amount of time. In Content Platform Migration Strategy - Artifacts vs Perishable Content we examined two content types - Artifacts and Perishable content. Understanding the differences between Artifacts and Perishable content will allow us to explicitly respect their various lifespans. Additionally, some content may have been part of a project that failed to meet the success criteria outlined in the Request Phase. Any content that did not meet the metrics outlined in the Request Phase should be considered for deletion. How - Thankfully by adhering to to The Minimalist Approach to Content Governance our content should have some level of meta data associated with it that will allow us to quickly sort and understand how to deal with it. Content Management Systems like Oracle's Universal Content Management (UCM) natively allow you to create and save advanced searches that can use content meta data like folders, author, expiration date, security settings and custom meta data to pull back listings of content for examination. Additionally, analytics are available for all content items that allow us to determine if the usage is meeting success criteria that may have been previously outlined during the request phase. The lists that are produced from these approaches can be quickly reviewed for each project with the content owners and based on the nature of the content and success criteria undergo archiving or deletion. Impact - Retiring content that is no longer relevant will allow end users to have fast and relevant access to information across your enterprise. As we mentioned in our first post in this series - it is easy to quickly start producing content, but the challenge is ensuring that the environment is easy to navigate and use on the third week and during the third year. The light level of effort that was placed into the Request Phase of this process will set us up to keep content clean and relevant for a long time to come. With an up-to-date content repository users will be able to quickly find access to the information that is critical to their work processes. You might not get a holiday named in your honor managing the content system, but will appreciate their quick access to quality information.

• What happens when the USB key or SD card I've installed VMware ESXi on fails?

  - by ewwhite

  An SD (SDHC) card installed in an HP ProLiant DL380p Gen8 server running VMware ESXi just failed. I encountered some rather ominous looking messages on the vCenter console and in the HP ProLiant ILO event log... Lost connectivity to the device ... backing the boot filesystem. As a result, host configuration changes will not be saved to persistent storage. Embedded Flash/SD-CARD: Error writing media 0, physical block 848880: Stack Exception. VMware advocates the use of USB and SD (SDHC) boot devices for ESXi. It was one of the main reasons the smaller footprint ESXi was developed (versus the older ESX). I've spent much time highlighting the differences between ESXi's installable and embedded modes to coworkers and clients. However, these failures do seem to happen. In this case, this is my third instance. Luckily, this is a vSphere cluster with SAN storage. What steps should be taken to remediate this failure?

• SQL SERVER – Question to You – When to use Function and When to use Stored Procedure

  - by pinaldave

  This week has been very interesting week. I have asked few questions to users and have received remarkable participation on the subject. Q1) SQL SERVER – Puzzle – SELECT * vs SELECT COUNT(*) Q2) SQL SERVER – Puzzle – Statistics are not Updated but are Created Once Keeping the same spirit up, I am asking the third question over here. Q3) When to use User Defined Function and when to use Stored Procedure in your development? Personally, I believe that they are both different things - they cannot be compared. I can say, it will be like comparing apples and oranges. Each has its own unique use. However, they can be used interchangeably at many times and in real life (i.e., production environment). I have personally seen both of these being used interchangeably many times. This is the precise reason for asking this question. When do you use Function and when do you use Stored Procedure? What are Pros and Cons of each of them when used instead of each other? If you are going to answer that ‘To avoid repeating code, you use Function’ - please think harder! Stored procedure can do the same. In SQL Server Denali, even the stored procedure can return the result just like Function in SELECT statement; so if you are going to answer with ‘Function can be used in SELECT, whereas Stored Procedure cannot be used’ - again think harder! (link). Now, what do you say? I will post the answers of all the three questions with due credit next week.

• Ingredient Substitutes while Baking

  - by Rekha

  In our normal cooking, we substitute the vegetables for the gravies we prepare. When we start baking, we look for a good recipe. At least one or two ingredient will be missing. We do not know where to substitute what to bring same output. So we finally drop the plan of baking. Again after a month, we get the interest in baking. Again one or two lack of ingredient and that’s it. We keep on doing this for months. When I was going through the cooking blogs, I came across a site with the Ingredient Substitutes for Baking: (*) is to indicate that this substitution is ideal from personal experience. Flour Substitutes ( For 1 cup of Flour) All Purpose Flour 1/2 cup white cake flour plus 1/2 cup whole wheat flour 1 cup self-rising flour (omit using salt and baking powder if the recipe calls for it since self raising flour has it already) 1 cup plus 2 tablespoons cake flour 1/2 cup (75 grams) whole wheat flour 7/8 cup (130 grams) rice flour (starch) (do not replace all of the flour with the rice flour) 7/8 cup whole wheat Bread Flour 1 cup all purpose flour 1 cup all purpose flour plus 1 teaspoon wheat gluten (*) Cake Flour Place 2 tbsp cornstarch in 1 cup and fill the rest up with All Purpose flour (*) 1 cup all purpose flour minus 2 tablespoons Pastry flour Place 2 tbsp cornstarch in 1 cup and fill the rest up with All Purpose flour Equal parts of All purpose flour plus cake flour (*) Self-rising Flour 1½ teaspoons of baking powder plus ½ teaspoon of salt plus 1 cup of all-purpose flour. Cornstarch (1 tbsp) 2 tablespoons all-purpose flour 1 tablespoon arrowroot 4 teaspoons quick-cooking tapioca 1 tablespoon potato starch or rice starch or flour Tapioca (1 tbsp) 1 – 1/2 tablespoons all-purpose flour Cornmeal (stone ground) polenta OR corn flour (gives baked goods a lighter texture) if using cornmeal for breading,crush corn chips in a blender until they have the consistency of cornmeal. maize meal Corn grits Sweeteners ( for Every 1 cup ) * * (HV) denotes Healthy Version for low fat or fat free substitution in Baking Light Brown Sugar 2 tablespoons molasses plus 1 cup of white sugar Dark Brown Sugar 3 tablespoons molasses plus 1 cup of white sugar Confectioner’s/Powdered Sugar Process 1 cup sugar plus 1 tablespoon cornstarch Corn Syrup 1 cup sugar plus 1/4 cup water 1 cup Golden Syrup 1 cup honey (may be little sweeter) 1 cup molasses Golden Syrup Combine two parts light corn syrup plus one part molasses 1/2 cup honey plus 1/2 cup corn syrup 1 cup maple syrup 1 cup corn syrup Honey 1- 1/4 cups sugar plus 1/4 cup water 3/4 cup maple syrup plus 1/2 cup granulated sugar 3/4 cup corn syrup plus 1/2 cup granulated sugar 3/4 cup light molasses plus 1/2 cup granulated white sugar 1 1/4 cups granulated white or brown sugar plus 1/4 cup additional liquid in recipe plus 1/2 teaspoon cream of tartar Maple Syrup 1 cup honey,thinned with water or fruit juice like apple 3/4 cup corn syrup plus 1/4 cup butter 1 cup Brown Rice Syrup 1 cup Brown sugar (in case of cereals) 1 cup light molasses (on pancakes, cereals etc) 1 cup granulated sugar for every 3/4 cup of maple syrup and increase liquid in the recipe by 3 tbsp for every cup of sugar.If baking soda is used, decrease the amount by 1/4 teaspoon per cup of sugar substituted, since sugar is less acidic than maple syrup Molasses 1 cup honey 1 cup dark corn syrup 1 cup maple syrup 3/4 cup brown sugar warmed and dissolved in 1/4 cup of liquid ( use this if taste of molasses is important in the baked good) Cocoa Powder (Natural, Unsweetened) 3 tablespoons (20 grams) Dutch-processed cocoa plus 1/8 teaspoon cream of tartar, lemon juice or white vinegar 1 ounce (30 grams) unsweetened chocolate (reduce fat in recipe by 1 tablespoon) 3 tablespoons (20 grams) carob powder Semisweet baking chocolate (1 oz) 1 oz unsweetened baking chocolate plus 1 Tbsp sugar Unsweetened baking chocolate (1 oz ) 3 Tbsp baking cocoa plus 1 Tbsp vegetable oil or melted shortening or margarine Semisweet chocolate chips (1 cup) 6 oz semisweet baking chocolate, chopped (Alternatively) For 1 cup of Semi sweet chocolate chips you can use : 6 tablespoons unsweetened cocoa powder, 7 tablespoons sugar ,1/4 cup fat (butter or oil) Leaveners and Diary * * (HV) denotes Healthy Version for low fat or fat free substitution in Baking Compressed Yeast (1 cake) 1 envelope or 2 teaspoons active dry yeast 1 packet (1/4 ounce) Active Dry yeast 1 cake fresh compressed yeast 1 tablespoon fast-rising active yeast Baking Powder (1 tsp) 1/3 teaspoon baking soda plus 1/2 teaspoon cream of tartar 1/2 teaspoon baking soda plus 1/2 cup buttermilk or plain yogurt 1/4 teaspoon baking soda plus 1/3 cup molasses. When using the substitutions that include liquid, reduce other liquid in recipe accordingly Baking Soda(1 tsp) 3 tsp Baking Powder ( and reduce the acidic ingredients in the recipe.

If it calls for baking soda and cream of tarter, just use baking powder.Normally, when cream of tartar is used in a cookie, it is used together with baking soda. The two of them combined work like double-acting baking powder. When substituting for cream of tartar, you must also substitute for the baking soda. If your recipe calls for baking soda and cream of tarter, just use baking powder. One teaspoon baking powder is equivalent to 1/4 teaspoon baking soda plus 5/8 teaspoon cream of tartar.

• ISA 2006 refuses VPN DHCP requests as spoofing

  - by Daniel

  I'm running ISA 2006 with PPTP VPN for my AD-controlled network. DHCP is located on the ISA server itself and authentication is done by RADIUS (NPS) located on the DC. Right now my VPN clients can connect, access local DNS, and can ping ISA, the DC, and other clients. Here's where it gets weird. I noticed that despite all this, ipconfig shows the following: PPP adapter North Horizon VPN: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : North Horizon VPN Physical Address. . . . . . . . . : DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 10.42.4.7(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : 0.0.0.0 DNS Servers . . . . . . . . . . . : 10.42.1.10 NetBIOS over Tcpip. . . . . . . . : Enabled So I went over and checked my ISA logs for both DHCP requests and replies, only to find out that my VPN clients are being denied because ISA thinks its a spoof. Here's some relevant information from the log (the VPN subnet is 10.42.4.0/24): Client IP: 10.42.4.6 Destination: 255.255.255.255:67 Client Username: (blank) Protocol: DHCP (request) Action: Denied Connection Rule: (blank) Source Network: VPN Clients Destination Network: Local Host Result Code: 0xc0040014 FWX_E_FWE_SPOOFING_PACKET_DROPPED Network Interface: 10.42.4.11 --------------------------------------------------------- Original Client IP: 10.42.4.6 Destination: 10.42.1.1 Client Username: (valid user) Protocol: PING Action: Initiated Connection Rule: Allow PING to ISA Source Network: VPN Clients Destination Network: Local Host Result Code: 0x0 ERROR_SUCCESS Network Interface: (blank) I wasn't sure what this 10.42.4.11 network interface was - it certainly wasn't something I had setup - untill I saw it in Routing and Remote Access under IP Routing General as an interface called "Internal" bound to the same IP address. I also noticed that since ISA takes blocks of 10 IP addresses from DHCP for VPN, it had reserved 10.42.4.2-11. I'm not sure if it means anything, though. Thanks for your help.

• How to check a digital certificate?

  - by StackedCrooked

  I have extracted a certificate from a cable modem. Now I want to verify if this certificate is valid. If I understand correctly, the verification process consists of having the issuer sign the subject's public key and then comparing the result with the subject's signature. This signing process is done using the issuer's private key, which nobody but the issuer has access to. So even if I have both certificates on my PC, there is no way for me to verify the subject's validity. From this I can only conclude that the verification must be implemented as a remote service. The problem is that I don't know what remote service I need to access to verify this certificate. The issuer is "AVM GmbH Cable Modem Root Certificate Authority". How can I find the webservice for verification? Is there standard lookup mechanism for this?

• Modify Build Failure Work Item in TFS 2010 Build

  - by Jakob Ehn

  The default behaviour in TFS Team Build (all versions) is to create a bug work item when a build fails. This main benefit of this is that you get a work item for something that needs to be done, namely to fix the build!. When the developer responsible for the build failure has fixed the problem, he/she can associated that check-in with the work item that was created from the previous build failure. In TFS 2005/2008 you could modify the information in the created work item by changing some predefined properties in the TFSBuild.proj file:   <!-- WorkItemType The type of the work item created on a build failure. --> <WorkItemType>Bug</WorkItemType> <!-- WorkItemFieldValues Fields and values of the work item created on a build failure. Note: Use reference names for fields if you want the build to be resistant to field name changes. Reference names are language independent while friendly names are changed depending on the installed language. For example, "System.Reason" is the reference name for the "Reason" field. --> <WorkItemFieldValues>System.Reason=Build Failure;System.Description=Start the build using Team Build</WorkItemFieldValues> <!-- WorkItemTitle Title of the work item created on build failure. --> <WorkItemTitle>Build failure in build:</WorkItemTitle> <!-- DescriptionText History comment of the work item created on a build failure. --> <DescriptionText>This work item was created by Team Build on a build failure.</DescriptionText> <!-- BuildLogText Additional comment text for the work item created on a build failure. --> <BuildlogText>The build log file is at:</BuildlogText> <!-- ErrorWarningLogText Additional comment text for the work item created on a build failure. This text will only be added if there were errors or warnings. --> <ErrorWarningLogText>The errors/warnings log file is at:</ErrorWarningLogText>   In TFS 2010, with Windows Workflow, you change this by modifying the properties on the OpenWorkItem activity. The hardest part of this is to actually find where this activity is located in the build process workflow. If you open the build definition in XAML you can just search for OpenWorkItem. If you use the designer you need to click your way down to the Catch section of the Try to Compile the Project sequence: To change the default values of the created work item, select the Created Work Item activity and look at the Properties window: Note the CustomFields property which is a dictionary with key (work item field name) and value. If you add custom fields to your work item you can add a value for it here by adding a new entry in the dictionary.

• How to I set up nfs using the Drobo Unfsd app?

  - by Jan Aagaard

  How do I set up my nfs on my Drobo FS so that I can connect to it from my Mac using the NFS protocol? I have downloaded and installed Unfsd program from the DroboApps page. My exports file looks like this: /mnt/DroboFS/Shares 192.168.1.0/255.255.255.0(rw,no_root_squash) I try to connect to the share by hitting Ctrl+K in Finder and the using nfs://drobo-fs.local/Shares as server address. But when I click Connect all that happens is that the Connect to Server window flashes shortly, and well, that's all. I have tried removing the /Shares part, using /Public and casing drobo-fs.local as Drobo-FS.local, but it's all with the same result. I have also tried using /mnt/DroboFS/Shares *(rw,no_root_squash) in the exports file. I restart the service using the command ./service.sh restart.

• Ask the Readers: Do You Prefer Computers, Game Consoles, or Other Devices for Your Gaming Needs?

  - by Asian Angel

  Nearly everyone who has access to a computer will play games on it at some point, but many people also use a separate game platform as well. What we would like to know this week is if you prefer using a computer, game consoles, or other devices for your gaming needs. Photo of Faith and Kate Connors from Mirror’s Edge by Tamahikari Tammas. Video games are a perfect way to relax and have fun at home (or at work if you can sneak in some game time!). The increasing variety of devices available with each passing year are making it easier to have access to a gaming platform to suit your needs or “darkest gaming desires”. For many people their computers are the perfect platform…they can play Flash-based games in their browsers, use the default set of games that come with their system, and install any extras that catch their eyes. The added benefit is that when game time is over they can drop right into their browsing, e-mail, personal projects, or work without having to switch hardware. The convenience of the “all-in-one” platform is certainly appealing! Perhaps you prefer to use your computer for other activities outside of gaming and own one or more separate game consoles. You might have chosen an Xbox, Playstation, or Nintendo for example. Maybe a hand-held is preferable for its’ size and portability. Then there are mobile phones and the iPad… With so many options it may feel hard to choose the right platform(s) without a good bit of research regarding display, availability of games for a particular platform, how long before the platform starts to become “obsolete”, etc. What we would like to know this week is which gaming platform you prefer. Is there only one that you choose to use or do you use multiple platforms for gaming? Is there a particular reason such as convenience for your choices? You may even be keeping an older platform around just for a certain game (or games) made for it. Are there any recommendations or advice that you would like to share with your fellow readers?

• How to internally rewrite a page when requested from specific HTTP_HOST

  - by Andy

  Hi all, I have a Drupal site, site.com, and our client has a campaign that they're promoting for which they've bought a new domain name, campaign.com. I'd like it so that a request for campaign.com internally rewrites to a particular page of the Drupal site. Note Drupal uses an .htaccess file in the document root. The normal Drupal rewrite is # Rewrite URLs of the form 'x' to the form 'index.php?q=x'. RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !=/favicon.ico RewriteRule ^(.*)$ index.php?q=$1 [L,QSA] I added the following before the normal rewrite. # Custom URLS (eg. microsites) go here RewriteCond %{HTTP_HOST} =campaign.com RewriteCond %{REQUEST_URI} =/ RewriteRule ^ index.php?q=node/22 [L] Unfortunately it doesn't work, it just shows the homepage. Turning on the rewrite log I get this. 1. [rid#2da8ea8/initial] (3) [perdir D:/wamp/www/] strip per-dir prefix: D:/wamp/www/ - 2. [rid#2da8ea8/initial] (3) [perdir D:/wamp/www/] applying pattern '^' to uri '' 3. [rid#2da8ea8/initial] (2) [perdir D:/wamp/www/] rewrite '' - 'index.php?q=node/22' 4. [rid#2da8ea8/initial] (3) split uri=index.php?q=node/22 - uri=index.php, args=q=node/22 5. [rid#2da8ea8/initial] (3) [perdir D:/wamp/www/] add per-dir prefix: index.php - D:/wamp/www/index.php 6. [rid#2da8ea8/initial] (2) [perdir D:/wamp/www/] strip document_root prefix: D:/wamp/www/index.php - /index.php 7. [rid#2da8ea8/initial] (1) [perdir D:/wamp/www/] internal redirect with /index.php [INTERNAL REDIRECT] 8. [rid#2da7770/initial/redir#1] (3) [perdir D:/wamp/www/] strip per-dir prefix: D:/wamp/www/index.php - index.php 9.

Specifically uri and args on line 4 seem correct, the internal redirect on line 7 seems right, and the pass through on line 12 seems right (because the file index.php exists). But for some reason it seems the query string's been discarded/ignored around the time of the internal redirect. I'm completely stumped. Also, if anyone could provide a reference on understanding the rewrite log, that might help. It'd be great if there's a way to track the query string through the internal redirect. FWIW I'm using WampServer 2.1 with Apache 2.2.17.

• How to create Adhoc workflow in UCM

  - by vijaykumar.yenne

  UCM has an inbuilt workflow engine that can handle document centric workflow approval/rejection process to ensure the right set of assets go into the repository. Anybody who has gone through the documentation is aware that there are two types of work flows that can be defined using the Workflow Admin applet in UCM namely Criteria and Basic While criteria is an Automatic workflow  process based on certain metadata attributes (Security Group and One of the Metadata Fields) , basic workflow is a manual workflow that need to be initiated by the admin. Any workflow  that can be put on the white board can be translated into the UCM wokflow process and there are concepts like sub workflows, tokens, events. idoc scripting that be introduced to handle any kind of complex workflows. There is a specific Workflow Implementation guide that explains the concepts in detail. One of the standard queries i come across is how to handle adhoc workflows where at the time of contributing the content, the contributors would like to decide on the workflow to be initiated and the users to be picked for approval in each step, hence this post.This is what i want to acheive, i would like to display on my Checkin Screen on the kind of workflows that a contributor could choose from:Based on the Workflow the contributor chooses, the other metadata fields (Step One, Step Two and Step Three)  need to be filled in and these fields decide who the approvers are going to be.1. Create a criteria workflow called One_Step_Review2.create two tokens StepOne <$wfAddUser(xWorkflowStepOne, "user")$>,  OrginalAuthor  <$wfAddUser(wfGet("OriginalAuthor"), "user")$>View image3.create two steps in the work flow created (One_Step_Review)View image4. Edit Step1 of the Workflow and add the Step One token and select the review permissionView image5. In the exit conditions tab have atleast One reveiwerView image6. In the events tab add an entry event <$wfSet("OriginalAuthor",dDocAuthor)$> to capture the contributor who shall be notified in the second step of the workflowView image7. Add the second step Notify_Author to the workflow8. Add the original author token to the above step9.  Enable the workflow10. Open the configration manager applet and create a Metadata field Workflow with option list enabled and add the list of values as show hereView image11. Create another metadata field WorkflowStepOne with option list configured to the Users View. This shall display all the users registered with UCM, which when selected shall be associated with the tokens associated with the workflow. Refer the above token.View imageAs indicated in the above steps you could create multiple work flows and associate the custom metadata field values to the tokens so that the contributors can decide who can approve their  content.

• Option Trading: Getting the most out of the event session options

  - by extended_events

  You can control different aspects of how an event session behaves by setting the event session options as part of the CREATE EVENT SESSION DDL. The default settings for the event session options are designed to handle most of the common event collection situations so I generally recommend that you just use the defaults. Like everything in the real world though, there are going to be a handful of “special cases” that require something different. This post focuses on identifying the special cases and the correct use of the options to accommodate those cases. There is a reason it’s called Default The default session options specify a total event buffer size of 4 MB with a 30 second latency. Translating this into human terms; this means that our default behavior is that the system will start processing events from the event buffer when we reach about 1.3 MB of events or after 30 seconds, which ever comes first. Aside: What’s up with the 1.3 MB, I thought you said the buffer was 4 MB?The Extended Events engine takes the total buffer size specified by MAX_MEMORY (4MB by default) and divides it into 3 equally sized buffers. This is done so that a session can be publishing events to one buffer while other buffers are being processed. There are always at least three buffers; how to get more than three is covered later. Using this configuration, the Extended Events engine can “keep up” with most event sessions on standard workloads. Why is this? The fact is that most events are small, really small; on the order of a couple hundred bytes. Even when you start considering events that carry dynamically sized data (eg. binary, text, etc.) or adding actions that collect additional data, the total size of the event is still likely to be pretty small. This means that each buffer can likely hold thousands of events before it has to be processed. When the event buffers are finally processed there is an economy of scale achieved since most targets support bulk processing of the events so they are processed at the buffer level rather than the individual event level. When all this is working together it’s more likely that a full buffer will be processed and put back into the ready queue before the remaining buffers (remember, there are at least three) are full. I know what you’re going to say: “My server is exceptional! My workload is so massive it defies categorization!” OK, maybe you weren’t going to say that exactly, but you were probably thinking it. The point is that there are situations that won’t be covered by the Default, but that’s a good place to start and this post assumes you’ve started there so that you have something to look at in order to determine if you do have a special case that needs different settings. So let’s get to the special cases… What event just fired?! How about now?! Now?! If you believe the commercial adage from Heinz Ketchup (Heinz Slow Good Ketchup ad on You Tube), some things are worth the wait. This is not a belief held by most DBAs, particularly DBAs who are looking for an answer to a troubleshooting question fast. If you’re one of these anxious DBAs, or maybe just a Program Manager doing a demo, then 30 seconds might be longer than you’re comfortable waiting. If you find yourself in this situation then consider changing the MAX_DISPATCH_LATENCY option for your event session. This option will force the event buffers to be processed based on your time schedule. This option only makes sense for the asynchronous targets since those are the ones where we allow events to build up in the event buffer – if you’re using one of the synchronous targets this option isn’t relevant. Avoid forgotten events by increasing your memory Have you ever had one of those days where you keep forgetting things? That can happen in Extended Events too; we call it dropped events. In order to optimizes for server performance and help ensure that the Extended Events doesn’t block the server if to drop events that can’t be published to a buffer because the buffer is full. You can determine if events are being dropped from a session by querying the dm_xe_sessions DMV and looking at the dropped_event_count field. Aside: Should you care if you’re dropping events?Maybe not – think about why you’re collecting data in the first place and whether you’re really going to miss a few dropped events. For example, if you’re collecting query duration stats over thousands of executions of a query it won’t make a huge difference to miss a couple executions. Use your best judgment. If you find that your session is dropping events it means that the event buffer is not large enough to handle the volume of events that are being published. There are two ways to address this problem. First, you could collect fewer events – examine you session to see if you are over collecting. Do you need all the actions you’ve specified? Could you apply a predicate to be more specific about when you fire the event? Assuming the session is defined correctly, the next option is to change the MAX_MEMORY option to a larger number. Picking the right event buffer size might take some trial and error, but a good place to start is with the number of dropped events compared to the number you’ve collected. Aside: There are three different behaviors for dropping events that you specify using the EVENT_RETENTION_MODE option. The default is to allow single event loss and you should stick with this setting since it is the best choice for keeping the impact on server performance low.You’ll be tempted to use the setting to not lose any events (NO_EVENT_LOSS) – resist this urge since it can result in blocking on the server. If you’re worried that you’re losing events you should be increasing your event buffer memory as described in this section. Some events are too big to fail A less common reason for dropping an event is when an event is so large that it can’t fit into the event buffer. Even though most events are going to be small, you might find a condition that occasionally generates a very large event. You can determine if your session is dropping large events by looking at the dm_xe_sessions DMV once again, this time check the largest_event_dropped_size. If this value is larger than the size of your event buffer [remember, the size of your event buffer, by default, is max_memory / 3] then you need a large event buffer. To specify a large event buffer you set the MAX_EVENT_SIZE option to a value large enough to fit the largest event dropped based on data from the DMV. When you set this option the Extended Events engine will create two buffers of this size to accommodate these large events. As an added bonus (no extra charge) the large event buffer will also be used to store normal events in the cases where the normal event buffers are all full and waiting to be processed. (Note: This is just a side-effect, not the intended use. If you’re dropping many normal events then you should increase your normal event buffer size.) Partitioning: moving your events to a sub-division Earlier I alluded to the fact that you can configure your event session to use more than the standard three event buffers – this is called partitioning and is controlled by the MEMORY_PARTITION_MODE option. The result of setting this option is fairly easy to explain, but knowing when to use it is a bit more art than science. First the science… You can configure partitioning in three ways: None, Per NUMA Node & Per CPU. This specifies the location where sets of event buffers are created with fairly obvious implication. There are rules we follow for sub-dividing the total memory (specified by MAX_MEMORY) between all the event buffers that are specific to the mode used: None: 3 buffers (fixed)Node: 3 * number_of_nodesCPU: 2.5 * number_of_cpus Here are some examples of what this means for different Node/CPU counts: Configuration None Node CPU 2 CPUs, 1 Node 3 buffers 3 buffers 5 buffers 6 CPUs, 2 Node 3 buffers 6 buffers 15 buffers 40 CPUs, 5 Nodes 3 buffers 15 buffers 100 buffers   Aside: Buffer size on multi-processor computersAs the number of Nodes or CPUs increases, the size of the event buffer gets smaller because the total memory is sub-divided into more pieces. The defaults will hold up to this for a while since each buffer set is holding events only from the Node or CPU that it is associated with, but at some point the buffers will get too small and you’ll either see events being dropped or you’ll get an error when you create your session because you’re below the minimum buffer size. Increase the MAX_MEMORY setting to an appropriate number for the configuration. The most likely reason to start partitioning is going to be related to performance. If you notice that running an event session is impacting the performance of your server beyond a reasonably expected level [Yes, there is a reasonably expected level of work required to collect events.] then partitioning might be an answer. Before you partition you might want to check a few other things: Is your event retention set to NO_EVENT_LOSS and causing blocking? (I told you not to do this.) Consider changing your event loss mode or increasing memory. Are you over collecting and causing more work than necessary? Consider adding predicates to events or removing unnecessary events and actions from your session. Are you writing the file target to the same slow disk that you use for TempDB and your other high activity databases? <kidding> <not really> It’s always worth considering the end to end picture – if you’re writing events to a file you can be impacted by I/O, network; all the usual stuff. Assuming you’ve ruled out the obvious (and not so obvious) issues, there are performance conditions that will be addressed by partitioning. For example, it’s possible to have a successful event session (eg. no dropped events) but still see a performance impact because you have many CPUs all attempting to write to the same free buffer and having to wait in line to finish their work. This is a case where partitioning would relieve the contention between the different CPUs and likely reduce the performance impact cause by the event session. There is no DMV you can check to find these conditions – sorry – that’s where the art comes in. This is  largely a matter of experimentation. On the bright side you probably won’t need to to worry about this level of detail all that often. The performance impact of Extended Events is significantly lower than what you may be used to with SQL Trace. You will likely only care about the impact if you are trying to set up a long running event session that will be part of your everyday workload – sessions used for short term troubleshooting will likely fall into the “reasonably expected impact” category. Hey buddy – I think you forgot something OK, there are two options I didn’t cover: STARTUP_STATE & TRACK_CAUSALITY. If you want your event sessions to start automatically when the server starts, set the STARTUP_STATE option to ON. (Now there is only one option I didn’t cover.) I’m going to leave causality for another post since it’s not really related to session behavior, it’s more about event analysis. - Mike Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• The Making of Arduino [Geek History]

  - by Jason Fitzpatrick

  The open-source Arduino board is the heart of thousands of different DIY projects–it would be easy to think that the Arduino has always been around. The ubiquitous little hobby board, however, is but a scant six years old. At technology blog IEEESpectrum they delve into the history of the Arduino board and its quiet origins in a small Italian town. Here’s an excerpt from their lengthy write up about the the origin and history of the beloved Arduino: Arduino is a low-cost microcontroller board that lets even a novice do really amazing things. You can connect an Arduino to all kinds of sensors, lights, motors, and other devices and use easy-to-learn software to program how your creation will behave. You can build an interactive display or a mobile robot and then share your design with the world by posting it on the Net. Released in 2005 as a modest tool for Banzi’s students at the Interaction Design Institute Ivrea (IDII), Arduino has spawned an international do-it-yourself revolution in electronics. You can buy an Arduino board for just about US $30 or build your own from scratch: All hardware schematics and source code are available for free under public licenses. As a result, Arduino has become the most influential open-source hardware movement of its time. The little board is now the go-to gear for artists, hobbyists, students, and anyone with a gadgetry dream. More than 250 000 Arduino boards have been sold around the world—and that doesn’t include the reams of clones. “It made it possible for people do things they wouldn’t have done otherwise,” says David A. Mellis, who was a student at IDII before pursuing graduate work at the MIT Media Lab and is the lead software developer of Arduino.
