• How to define AUTHPARAMS in Amazon EC2 API call

  - by The Joker

  I am trying to make an API call to EC2. I want to add my IP address to the security group. https://ec2.amazonaws.com/ ?Action=AuthorizeSecurityGroupIngress &GroupName=grppp20 &GroupId=sg-b2z982mq &IpPermissions.1.IpProtocol=tcp &IpPermissions.1.FromPort=3389 &IpPermissions.1.ToPort=3389 &IpPermissions.1.IpRanges.1.CidrIp=22.951.17.728/32 &&AWSAccessKeyId=AOPLDRACULALK6U7A And i get the following error. AWS was not able to validate the provided access credentials I have a secret access key & a username. I searched internet & found that we have to make a signature of the secret key & use it in the request instead of adding it directly. Can anyone tell me how to make a signature of my AWS secret key & how to use them with my API call? Let my secret key be: 2WwRiQzBs7RTFG4545PIOJ7812CXZ Username: thejoker

• End user query syntax?

  - by weberc2

  I'm making a command line tool that allows end users to query a statically-schemed database; however, I want users to be able to specify boolean matchers in their query (effectively things like "get rows where (field1=abcd && field2=efgh) || field3=1234"). I did Googling a solution, but I couldn't find anything suitable for end users--still, this seems like it would be a very common problem so I suspect there is a standard solution. So: What (if any) standard query "languages" are there that might be appropriate for end users? What (if any) de facto standards are there (for example, Unix tools that solve similar problems). Failing the previous two options, can you suggest a syntax that would be simple, concise, and easy to validate?

• Ruby but not Rails on my Resume

  - by Ken Bloom

  I have listed Ruby as a skill on my resume becuase I've been programming in Ruby for 5 years while I work on my Ph.D. thesis. I've mostly been using it to implement natural language processing algorithms. I'm starting to look for a job, and I posted my resume to a few sites (as an extra bonus when applying to certain on-target jobs). Now I get recruiters calling me to offer me Ruby on Rails jobs. The problem is that I've never learned Rails. It was never relevant to what I'm doing for my Ph.D. How do you recommend handling this situation to avoid wasting my time and theirs? (And learning Rails probably isn't an option until I finish my thesis.) Can my resume be adjusted to make this clearer? Should it be adjusted? Should I just politely tell them on the phone that I don't know Rails? By the way, the relevant part of my resume simply says: Skills: Programming Languages: C, C++, Java, Scala, Ruby, LaTeX Databases: MySQL, XML, XPath and lists a few other skill areas that couldn't possibly be confused with a Rails developer.

• Token based Authentication for WCF HTTP/REST Services: Authentication

  - by Your DisplayName here!

  This post shows some of the implementation techniques for adding token and claims based security to HTTP/REST services written with WCF. For the theoretical background, see my previous post. Disclaimer The framework I am using/building here is not the only possible approach to tackle the problem. Based on customer feedback and requirements the code has gone through several iterations to a point where we think it is ready to handle most of the situations. Goals and requirements The framework should be able to handle typical scenarios like username/password based authentication, as well as token based authentication The framework should allow adding new supported token types Should work with WCF web programming model either self-host or IIS hosted Service code can rely on an IClaimsPrincipal on Thread.CurrentPrincipal that describes the client using claims-based identity Implementation overview In WCF the main extensibility point for this kind of security work is the ServiceAuthorizationManager. It gets invoked early enough in the pipeline, has access to the HTTP protocol details of the incoming request and can set Thread.CurrentPrincipal. The job of the SAM is simple: Check the Authorization header of the incoming HTTP request Check if a “registered” token (more on that later) is present If yes, validate the token using a security token handler, create the claims principal (including claims transformation) and set Thread.CurrentPrincipal If no, set an anonymous principal on Thread.CurrentPrincipal. By default, anonymous principals are denied access – so the request ends here with a 401 (more on that later). To wire up the custom authorization manager you need a custom service host – which in turn needs a custom service host factory. The full object model looks like this: Token handling A nice piece of existing WIF infrastructure are security token handlers. Their job is to serialize a received security token into a CLR representation, validate the token and turn the token into claims. The way this works with WS-Security based services is that WIF passes the name/namespace of the incoming token to WIF’s security token handler collection. This in turn finds out which token handler can deal with the token and returns the right instances. For HTTP based services we can do something very similar. The scheme on the Authorization header gives the service a hint how to deal with an incoming token. So the only missing link is a way to associate a token handler (or multiple token handlers) with a scheme and we are (almost) done. WIF already includes token handler for a variety of tokens like username/password or SAML 1.1/2.0. The accompanying sample has a implementation for a Simple Web Token (SWT) token handler, and as soon as JSON Web Token are ready, simply adding a corresponding token handler will add support for this token type, too. All supported schemes/token types are organized in a WebSecurityTokenHandlerCollectionManager and passed into the host factory/host/authorization manager. Adding support for basic authentication against a membership provider would e.g. look like this (in global.asax): var manager = new WebSecurityTokenHandlerCollectionManager(); manager.AddBasicAuthenticationHandler((username, password) => Membership.ValidateUser(username, password));   Adding support for Simple Web Tokens with a scheme of Bearer (the current OAuth2 scheme) requires passing in a issuer, audience and signature verification key: manager.AddSimpleWebTokenHandler(     "Bearer",     "http://identityserver.thinktecture.com/trust/initial",     "https://roadie/webservicesecurity/rest/",     "WFD7i8XRHsrUPEdwSisdHoHy08W3lM16Bk6SCT8ht6A="); In some situations, SAML token may be used as well. The following configures SAML support for a token coming from ADFS2: var registry = new ConfigurationBasedIssuerNameRegistry(); registry.AddTrustedIssuer( "d1 c5 b1 25 97 d0 36 94 65 1c e2 64 fe 48 06 01 35 f7 bd db", "ADFS"); var adfsConfig = new SecurityTokenHandlerConfiguration(); adfsConfig.AudienceRestriction.AllowedAudienceUris.Add( new Uri("https://roadie/webservicesecurity/rest/")); adfsConfig.IssuerNameRegistry = registry; adfsConfig.CertificateValidator = X509CertificateValidator.None; // token decryption (read from config) adfsConfig.ServiceTokenResolver = IdentityModelConfiguration.ServiceConfiguration.CreateAggregateTokenResolver();             manager.AddSaml11SecurityTokenHandler("SAML", adfsConfig);   Transformation The custom authorization manager will also try to invoke a configured claims authentication manager. This means that the standard WIF claims transformation logic can be used here as well. And even better, can be also shared with e.g. a “surrounding” web application. Error handling A WCF error handler takes care of turning “access denied” faults into 401 status codes and a message inspector adds the registered authentication schemes to the outgoing WWW-Authenticate header when a 401 occurs. The next post will conclude with authorization as well as the source code download.   (Wanna learn more about federation, WIF, claims, tokens etc.? Click here.)

• Calling Web Services using ADF 11g

  - by James Taylor

  One of the benefits of ADF is that fact that it can use multiple data sources. With SOA playing a big part in today’s IT landscape, applications need to be able to utilise this SOA framework to leverage functionality from multiple systems to provide a composite application. ADF provides functionality to expose web services via the ADF Business Component so if you know how to use Business Components for a database. Configuring ADF for web services is much the same. In this example I use an OSB web service that gets a customer. Create a new Fusion Web Application (ADF) Application and click OK    Provide an Application Name, GetCustomerADF and click Next    From the Project Technologies move Web Services into the Selected box. Accept the defaults and click Finish. Right-click the Model project and select New In the Gallery select Web Services –> Web Service Data Control then click OK. Provide a name GetCustomerDC and give the URL endpoint for the Web Service, then click Next Select the web service operation you want to use for the ADF application. In my example my web service only has one operation. Click Finish Save your work, File –> Save The data control has now been created, the next steps create the UI components. In your application created in step 1 find the ViewController project, right-click and choose New In the Gallery select JSF –> JSF Page Provide a name for the jsp page, GetCustomer, Also ensure that the ‘Create as XML Document (*.jsp) check box is checked. I have selected the page template, Oracle Three Column Layout but you can create a layout of your choice. I only want 2 columns so I delete the last column but right-clicking the right had panel and selecting Delete Drag the fields you require from the web service data control to the left pannel. In my example I only require the Customer ID. When you drag to the panel select Texts –>ADF Input Text w/Label In this example I want to search on a customer based on the ID. So Once I select the ID I want to execute the request. To do this I need a button. Drag the operation object under the fields created in step 15. Select Methods –> ADF Button. You now need to provide the mappings, Choose the ‘Show EI Expression Builder’ Navigate to the bindings, ADFBindings –> bindings –> parametersIterator –> currentRow Click OK Drag and drop the return information I just want the results shown in a form. I want to show all fields Now it is time to test, Right-click the jspx page created in steps 11 – 21 and select Run A browser should start, enter valid values and test

• SQL SERVER – Weekly Series – Memory Lane – #006

  - by pinaldave

  Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2006 This was my very first year of blogging so I was every day learning something new. As I have said many times, that blogging was never an intention. I had really not understood what exactly I am working on or beginning when I was beginning blogging in 2006. I had never knew that my life was going to change forever, once I started blogging. When I look back all of this year, I am happy that we are here together. 2007 IT Outsourcing to India – Top 10 Reasons Companies Outsource Outsourcing is about trust, collaboration and success. Helping other countries in need has been always the course of mankind, outsourcing is nothing different then that. With information technology and process improvements increasing the complexity, costs and skills required to accomplish routine tasks as well as challenging complex tasks, companies are outsourcing such tasks to providers who have the expertise to perform them at lower costs , with greater value and quality outcome. UDF – Remove Duplicate Chars From String This was a very interesting function I wrote in my early career. I am still using this function when I have to remove duplicate chars from strings. I have yet to come across a scenario where it does not work so I keep on using it till today. Please leave a comment if there is any better solution to this problem. FIX : Error : 3702 Cannot drop database because it is currently in use This is a very generic error when DROP Database is command is executed and the database is not dropped. The common mistake user is kept the connection open with this database and trying to drop the database. The database cannot be dropped if there is any other connection open along with it. It is always a good idea to take database in single user mode before dropping it. Here is the quick tutorial regarding how to bring the database in single user mode: Using T-SQL | Using SSMS. 2008 Install SQL Server 2008 – How to Upgrade to SQL Server 2008 – Installation Tutorial This was indeed one of the most popular articles in SQL Server 2008. Lots of people wanted to learn how to install SQL SErver 2008 but they were facing various issues while installation. I build this tutorial which becomes reference points for many. Default Collation of SQL Server 2008 What is the collation of SQL Server 2008 default installations? I often see this question confusing many experienced developers as well. Well the answer is in following image. Ahmedabad SQL Server User Group Meeting – November 2008 User group meetings are fun, now a days I am going to User Group meetings every week but there was a case when I have been just a beginner on this subject. The bug of the community was caught on me years ago when I started to present in Ahmedabad and Gandhinagar SQ LServer User Groups. 2009 Validate an XML document in TSQL using XSD My friend Jacob Sebastian wrote an excellent article on the subject XML and XSD. Because of the ‘eXtensible’ nature of XML (eXtensible Markup Language), often there is a requirement to restrict and validate the content of an XML document to a pre-defined structure and values. XSD (XML Schema Definition Language) is the W3C recommended language for describing and validating XML documents. SQL Server implements XSD as XML Schema Collections. Star Join Query Optimization At present, when queries are sent to very large databases, millions of rows are returned. Also the users have to go through extended query response times when joining multiple tables are involved with such queries. ‘Star Join Query Optimization’ is a new feature of SQL Server 2008 Enterprise Edition. This mechanism uses bitmap filtering for improving the performance of some types of queries by the effective retrieval of rows from fact tables. 2010 These puzzles are very interesting and intriguing – there was lots of interest on this subject. If you have free time this weekend. You may want to try them out. SQL SERVER – Challenge – Puzzle – Usage of FAST Hint (Solution)  SQL SERVER – Puzzle – Challenge – Error While Converting Money to Decimal (Solution)  SQL SERVER – Challenge – Puzzle – Why does RIGHT JOIN Exists (Open)  Additionally, I had great fun presenting SQL Server Performance Tuning seminar at fantastic locations in Hyderabad. Installing AdventeWorks Database This has been the most popular request I have received on my blog. Here is the quick video about how one can install AdventureWorks. 2011 Effect of SET NOCOUNT on @@ROWCOUNT There was an interesting incident once while I was presenting a session. I wrote a code and suddenly 10 hands went up in the air.  This was a bit surprise to me as I do not know why they all got alerted. I assumed that there should be something wrong with either project, screen or my display. However the real reason was very interesting – I suggest you read the complete blog post to understand this interesting scenario. Error: Deleting Offline Database and Creating the Same Name This is very interesting because once a user deletes the offline database the MDF and LDF file still exists and if the user attempts to create a new database with the same name it will give error. I found this very interesting and the blog explains the concept very quickly. Have you ever faced a similar situation?

• Why did Google remove the search box in developer tool from Chrome 22 stable release?

  - by Bruce

  In previous version of Chrome, there's the search box in developer tool, on the right top when I open it, just as shown below. (Sorry I can't upload image cuz' I don't have enough reputation for now.) http://i.minus.com/iklSx2vi0uzFB.JPG But, after I upgraded to the first release of Chrome 22 yesterday, that search box was gone, as shown below. http://i.minus.com/ibxXt9wnBekR7E.JPG It is such a useful search box that I rely on all the time, to search for something, or to validate an xpath. So does Google just 'hide' it somewhere else? Or do they really remove it? Anyone know why they made such changes?

• Eclipse Helios on OS X Snow Leopard crashes frequently when editing certain PHP files

  - by William

  I use Eclipse Helios (Eclipse Platform: 3.6.0.I20100608-0911, Eclipse IDE for PHP Developers: 1.3.0.20100617-0520) all the time on OS X (Snow Leopard), and it seems I only run into trouble whenever I'm editing a PHP file that's part of the WordPress blogging framework. When I move my cursor to a variable or function name, that often triggers the beach ball of death. I suspect Eclipse is trying to look up that variable/function and for some reason that causes an endless loop. Sometimes it's not just variables or functions. Just today I was trying to replace all occurrences of a quoted string. Every time I clicked "Replace All", the program would freeze immediately after the string was replaced and the text cursor was moved to the replaced position. I think the moving of the text cursor is important, because I got the same result when I searched for the string (thus moving the cursor), but NOT when I searched for a nonexistent string. I tried disabling everything in my preferences related to marked occurrences, hovering, code assistance, etc. Nothing helps. I use Eclipse for all my projects, and I find that it's only WordPress projects where this happens. Here's my eclipse.ini file: -startup ../../../plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library ../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx_1.1.0.v20100503 -product org.eclipse.epp.package.php.product --launcher.defaultAction openFile -showsplash org.eclipse.platform --launcher.XXMaxPermSize 512m --launcher.defaultAction openFile -vmargs -Dosgi.requiredJavaVersion=1.5 -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -XX:PermSize=128m -XX:MaxPermSize=128m -XX:MaxGCPauseMillis=10 -XX:MaxHeapFreeRatio=70 -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing -XX:CompileThreshold=5 -Xms128m -Xmx512m -Xss2m -Xdock:icon=../Resources/Eclipse.icns -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -framework ../../../plugins/org.eclipse.osgi.services_3.2.100.v20100503.jar I have 4GB of RAM, so I don't know if the problem is I'm underutilizing my resources.

This value will be overwritten using the values from the preferences I did some experimenting with the particular script that's giving me trouble. It's a hybrid of HTML and PHP, so Eclipse has to do both HTML and PHP validation. I wondered if the HTML validation had something to do with it, so I created a new file, copied the contents over, and messed with the doctype element. I found that if I replaced the well-formed XHTML 1.0 Strict doctype element with a generic doctype (as such: <!DOCTYPE html>), then I did not crash the program just by moving the cursor around. I set all HTML validation rules to "Ignore", but it still didn't solve my problems. For now, I'm just going to echo the doctype using PHP instead of entering it literally. That seems to prevent crashes. I notice that when I move the cursor around the document, Eclipse displays the "xpath" to my current location at the bottom of the screen. Sometimes there's a delay while it figures out my current path. Perhaps when it's validating against the Strict doctype, it has problems quickly calculating the xpath as I move the cursor around? Maybe it has a stack overflow that causes it to crash.

• Can't specify window's class in CCSM's Place Windows

  - by Anto

  Following this method, I wanted to "place" some of my windows on specific viewports. For instance, I want Xchat to always start on my top right viewport (x=2, y=1). But after I have set everything up and clicked the "Close" button to validate it (I don't have any other action button, like "OK" or "Apply"), the only thing that get saved up are the viewport X and Y coordinates. The window class (in my case class=Xchat) remains empty. This bug only occurs in the "Windows with fixed viewport" section; it works well in the "Windows with fixed placement mode", for instance. How can I solve or circumvent this issue ?

• Is data integrity possible without normalization?

  - by shuniar

  I am working on an application that requires the storage of location information such as city, state, zip code, latitude, and longitude. I would like to ensure: Location data is accurate Detroit, CA Detroit IS NOT in California Detroit, MI Detroit IS in Michigan Cities and states are spelled correctly California not Calefornia Detroit not Detriot Cities and states are named consistently Valid: CA Detroit Invalid: Cali california DET d-town The D Also, since city/zip data is not guaranteed to be static, updating this data in a normalized fashion could be difficult, whereas it could be implemented as a de facto location if it is denormalized. A couple thoughts that come to mind: A collection of reference tables that store a list of all states and the most common cities and zip codes that can grow over time. It would search the database for an exact or similar match and recommend corrections. Use some sort of service to validate the location data before it is stored in the database. Is it possible to fulfill these requirements without normalization, and if so, should I denormalize this data?

• OpenWorld Day 1

  - by Antony Reynolds

  A Day in the Life of an OpenWorld Attendee Part I Lots of people are blogging insightfully about OpenWorld so I thought I would provide some non-insightful remarks to buck the trend! With 50,000 attendees I didn’t expect to bump into too many people I knew, boy was I wrong!  I walked into the registration area and immediately was hailed by a couple of customers I had worked with a few months ago.  Moving to the employee registration area in a different hall I bumped into a colleague from the UK who was also registering.  As soon as I got my badge I bumped into a friend from Ireland!  So maybe OpenWorld isn’t so big after all! First port of call was Larrys Keynote.  As always Larry was provocative and thought provoking.  His key points were announcing the Oracle cloud offering in IaaS, PaaS and SaaS, pointing out that Fusion Apps are cloud enabled and finally announcing the 12c Database, making a big play of its new multi-tenancy features.  His contention was that multi-tenancy will simplify cloud development and provide better security by providing DB level isolation for applications and customers. Next day, Monday, was my first full day at OpenWorld.  The first session I attended was on monitoring of OSB, very interesting presentation on the benefits achieved by an Illinois area telco – US Cellular.  Great discussion of why they bought the SOA Management Packs and the benefits they are already seeing from their investment in terms of improved provisioning and time to market, as well as better performance insight and assistance with capacity planning. Craig Blitz provided a nice walkthrough of where Coherence has been and where it is going. Last night I attended the BOF on Managed File Transfer where Dave Berry replayed Oracles thoughts on providing dedicated Managed File Transfer as part of the 12c SOA release.  Dave laid out the perceived requirements and solicited feedback from the audience on what if anything was missing.  He also demoed an early version of the functionality that would simplify setting up MFT in SOA Suite and make tracking activity much easier. So much for Day 1.  I also ran into scores of old friends and colleagues and had a pleasant dinner with my friend from Ireland where I caught up on the latest news from Oracle UK.  Not bad for Day 1!

• Client Side Form Validation vs. Server Side Form Validation

  In my opinion, it is mandatory to validate data using client side and server side validation as a fail over process. The client side validation allows users to correct any error before they are sent to the web server for processing, and this allows for an immediate response back to the user regarding data that is not correct or in the proper format that is desired. In addition, this prevents unnecessary interaction between the user and the web server and will free up the server over time compared to doing only server side validation. Server validation is the last line of defense when it comes to validation because you can check to ensure the user’s data is correct before it is used in a business process or stored to a database. Honestly, I cannot foresee a scenario where I would only want to use one form of validation over another especially with the current cost of creating and maintaining data. In my opinion, the redundant validation is well worth the overhead.

• How should programmers handle email-username identity theft?

  - by Craige

  Background I recently signed up for an iTunes account, and found that somebody had fraudulently used MY email to register their iTunes account. Why Apple did not validate the email address, I will never know. Now I am told that I cannot use my email address to register a new iTunes account, as this email address is linked to an existing account. This got be thinking... Question How should we as developers handle email/identity theft? Obviously, we should verify that an email address belongs to the person it is said to belong to. Why Apple did not do this in my case, I have no idea. But lets pretend we use email address for login/account identification, and something slipped though the cracks (be it our end, or the users). How should we handle reports of fraudulent accounts?

• Limitations of User-Defined Customer Events (FA Type Profile)

  - by Rajesh Sharma

  CC&B automatically creates field activities when a specific Customer Event takes place. This depends on the way you have setup your Field Activity Type Profiles, the templates within, and associated SP Condition(s) on the template. CC&B uses the service point type, its state and referenced customer event to determine which field activity type to generate.   Customer events available in the base product include: Cut for Non-payment (CNP) Disconnect Warning (DIWA) Reconnect for Payment (REPY) Reread (RERD) Stop Service (STOP) Start Service (STRT) Start/Stop (STSP)   Note the Field values/codes defined for each event.   CC&B comes with a flexibility to define new set of customer events. These can be defined in the Look Up - CUST_EVT_FLG. Values from the Look Up are used on the Field Activity Type Profile Template page.     So what's the use of having user-defined Customer Events? And how will the system detect such events in order to create field activity(s)?   Well, system can only detect such events when you reference a user-defined customer event on a Severance Event Type for an event type Create Field Activities.     This way you can create additional field activities of a specific field activity type for user-defined customer events.   One of our customers adopted this feature and created a user-defined customer event CNPW - Cut for Non-payment for Water Services. This event was then linked on a Field Activity Type Profile and referenced on a Severance Event - CUT FOR NON PAY-W. The associated Severance Process was configured to trigger a reconnection process if it was cancelled (done by defining a Post Cancel Algorithm). Whenever this Severance Event was executed, a specific type of Field Activity was generated for disconnection purposes. The Field Activity type was determined by the system from the Field Activity Type Profile referenced for the SP Type, SP's state and the referenced user-defined customer event. All was working well until the time when they realized that in spite of the Severance Process getting cancelled (when a payment was made); the Post Cancel Algorithm was not executed to start a Reconnection Severance Process for the purpose of generating a reconnection field activity and reconnecting the service.   Basically, the Post Cancel algorithm (if specified on a Severance Process Template) is triggered when a Severance Process gets cancelled because a credit transaction has affected/relieved a Service Agreement's debt.   So what exactly was happening? Now we come to actual question as to what are limitations in having user-defined customer event.   System defined/base customer events are hard-coded across the entire system. There is an impact even if you remove any customer event entry from the Look Up. User-defined customer events are not recognized by the system anywhere else except in the severance process, as described above.   There are few programs which have routines to first validate the completion of disconnection field activities, which were raised as a result of customer event CNP - Cut for Non-payment in order to perform other associated actions. One such program is the Post Cancel Algorithm, referenced on a Severance Process Template, generally used to reconnect services which were disconnected from other Severance Event, specifically CNP - Cut for Non-Payment. Post cancel algorithm provided by the product - SEV POST CAN does the following (below is the algorithm's description):   This algorithm is called after a severance process has been cancelled (typically because the debt was paid and the SA is no longer eligible to be on the severance process). It checks to see if the process has a completed 'disconnect' event and, if so, starts a reconnect process using the Reconnect Severance Process Template defined in the parameter.    Notice the underlined text. This algorithm implicitly checks for Field Activities having completed status, which were generated from Severance Events as a result of CNP - Cut for Non-payment customer event.   Now if we look back to the customer's issue, we can relate that the Post Cancel algorithm was triggered, but was not able to find any 'Completed' CNP - Cut for Non-payment related field activity. And hence was not able to start a reconnection severance process. This was because a field activity was generated and completed for a customer event CNPW - Cut for Non-payment of Water Services instead.   To conclude, if you introduce new customer events, you should be aware that you don't extend or simulate base customer events, the ones that are included in the base product, as they are further used to provide/validate additional business functions.

• What's Your Supply Chain+Manufacturing Strategy for Success

  - by [email protected]

  Forward thinking enterprises look to eliminate their dependence on legacy applications that manage information in batch - replacing them with real-time integrated/modern information managment. With rapid manufacturing and global supply chains much more complex today, with the pace of chance ever increasing, leading organizations need better ways to orchestrate their supply chain synchronization with their partner and customer base. EM magazine Mar/Apr'10 edition, covers this topic in an article "Strategising for Success" pgs 26-27, and discusses the available options to organizations as they drive improvements in the levels of collaboration with their partners, suppliers, shippers, distributors and ultimately their end-users, the customer! I'll past the link to the article here as soon as i validate/confirm it.

• SEO optimisation problems after Google Panda [on hold]

  - by Daniel West

  I am currently trying to improve a website's SEO after it took quite a hit from the Google Panda upgrades. What are the main things I need to look at improving when trying to improve its ranking in Google? I have already made sure that the pages validate to W3C Standards, minimized css and js and done the obvious meta tags and header optimization but this hasn't made any difference yet. It could possibly be a content issue as the pages currently read much like a brochure and there were some pages with just a video and no text content on them which is also an issue. I've added a rel="nofollow" attribute to the links to these pages although i'm told this doesn't really work anymore. If anyone has any ideas let me know. Cheers!

• Salesforce deployment guideline using Sandbox

  - by ybbest

  Create Deployment connection Enable the inbound change set settings on the destination Environment you would like to deploy the solution to. Enable the outbound change set settings on the source Environment where you package your application. The best practice is to Package everything in the changeset and salesforce will only deploy the change into your destination environment. If you only package the change, you could miss some of the changes. You can clone the change set on the source destination however the initial packaging takes some time as you need to go through everything and select the components manually. After the change set is packaged, you need to upload the chagneset so that destination environment can see the change set in its incoming change set list. Click Validate the change set before deployment. References: Development Lifecycle Guide Change Sets Best Practices
