HBASE INDEXING LIBRARY : Copied From http://www.lilyproject.org/

WHAT?

This library aids in building and querying indexes on top of HBase, in Google App Engine datastore-style. This basically means querying by range-scanning on specifically constructed index tables.

The goal of this library is to hide the details of playing with HBase's byte[] row keys to construct indexes. Actually pushing data towards the index is not handled by this package.

This library is complementary to the tableindexed contrib module of HBase, which does not do much regarding row key construction, though at this time it was not specifically designed to work together.

Some background on the indexing approach in this package can be found in this blog post.

FEATURES

• define indexes consisting of one or more fields
• fields can be high-level datatypes like strings, integers, floats, decimals, date(time)s
• strings can be indexed as plain UTF8, ASCII-folded (= accents removed), or by collator key
• the entries in the index can be in ascending or descending order
• perform equals and range queries on all or a subset of the fields in the index (fields should be used left-to-right, only for the last used field a range can be used)
• results from multiple indexes can be streamingly merge-joined
• unrestricted scalability due to the automatic sharding (and replication) offered by HBase

Access data from a WITSML server

     import java.net.MalformedURLException;
     import java.net.URL;
     import java.util.List;

     import org.jwitsml.Capabilities;
     import org.jwitsml.WitsmlQuery;
     import org.jwitsml.WitsmlServer;
     import org.jwitsml.WitsmlServerException;
     import org.jwitsml.WitsmlVersion;
     import org.jwitsml.WitsmlWell;

     public class BasicExample {
       public static void main(String[] arguments) {
         try {
           // Identify ourself and our capabilities as WITSML client

Getting WITSML data from the server

All data is retrieved through a WitsmlServer instance which represents the WITSML server in the client program.

There are three different ways to get data:

1. Get multiple children of a given type from a specific parent

     
     // Get all wellbores from a given well instance
     List<WitsmlWellbore> wellbores = witsmlServer.get(WitsmlWellbore.class,
                                                       new WitsmlQuery(),
                                                       well);

     
     // Get all rigs from a given wellbore instance
     List<WitsmlRig> rigs = witsmlServer.get(WitsmlRig.class,
                                             new WitsmlQuery(),
                                             wellbore);

     
     // ... or through the wellbore ID
     List<WitsmlRig> rigs = witsmlServer.get(WitsmlRig.class,
                                             new WitsmlQuery(),
                                             "ID-wellbore");

     
     // Both parent and grandparent may be specified
     List<WitsmlMudLog> mudLogs = witsmlServer.get(WitsmlMudLog.class,
                                                   new WitsmlQuery(),
                                                   "ID-wellbore",
                                                   "ID-well");

     
     // Wells doesn't have parents so we can skip the parent argument
     List<WitsmlWell> wells = witsmlServer.get(WitsmlWell.class,
                                               new WitsmlQuery());

     
     // Attempt to get all rigs! Some servers will accept this approach
     // while others will require a valid wellbore parent.
     // The WITSML standard is unclear on this issue.
     List<WitsmlRig> rigs = witsmlServer.get(WitsmlRig.class,
                                             new WitsmlQuery());

HBase Schema Design - Things you need to know

 

When designing schemas for HBase, be it from scratch or porting an existing application over from a relational database for example, there are a set of architectural constraints that a user should be aware of to avoid common pitfalls. This session discusses the basic underlying concepts of the storage

Content Types

Content types are a fundamental concept of SharePoint foundation. Any data that you put inside
SharePoint gets associated with some content type. Any content type gives you a number of reusable
settings. The reusable settings consist of the structure of information, associated workflows, information management policies, field rendering templates, and in the case of documents—document information panels and document formats and templates.
As an example in your organization, you may produce proposals for clients or software defect bug
reports. It is possible that both of these are Word documents, but their meanings are quite different. The workflows that they need to be routed through are quite different and the associated collected metadata on each of these can also be quite different. Therefore, it makes sense to differentiate between them as their own content types.

ADO.NET Data Services and REST

ADO.NET Data Services is yet another way for you to access your SharePoint data at client side. Under
this technology you would use patterns and libraries that make data accessible over simple HTTP-based
technologies. This means that you can access the data over simple HTTP-based URIs and use of
standard HTTP verbs such as GET, PUT, POST, and DELETE. Data is fetched in JSON or ATOM formats,  so it is portable across all platforms.

How to Register DLL Control Panel Items

Control Panel items that are implemented in a DLL that exports the CPlApplet function have different registration requirements than .exe files. For Windows XP and later systems, new Control Panel item DLLs should be installed in the associated application's folder under the Program Files folder. Items that are stored in the System32 directory with a .cpl extension do not need to be registered; they are automatically shown in the Control Panel. All other Control Panel items usingCPlApplet must be registered in one of two ways:

• If the Control Panel item is to be available to all users, register the path on a per-computer basis by adding a REG_EXPAND_SZ value to theHKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Control Panel\Cpls subkey, set to the DLL path.
• If the Control Panel item is to be available on a per-user basis, use HKEY_CURRENT_USER as the root key instead of HKEY_LOCAL_MACHINE.

The following two examples register the MyCplApp Control Panel item. The DLL is named MyCpl.cpl and is located in the MyCorp\MyApp application directory. This first example illustrates per-computer registration.

Instructions

Step 1:

Add this information to the registry to register the existence of the .cpl file.

HKEY_LOCAL_MACHINE    Software       Microsoft          Windows             CurrentVersion                Control Panel                   Cpls                      MyCpl = [REG_EXPAND_SZ] %ProgramFiles%\MyCorp\MyApp\MyCpl.cpl

How to Register Executable Control Panel Items

 

For Control Panel items that are implemented as .exe files, no special exports or message handling is required. Any .exe file can be registered as a command object to appear with an entry point in the Control Panel folder.
An example is used here to demonstrate the registration requirements. The example shows how to register a Control Panel item called My Settings as a command object so that it appears in the Control Panel window. The My Settings window also appears when the command MyApp.exe /settings is run.

Instructions

Step 1:

Generate a GUID for the Control Panel item. The GUID uniquely identifies the Control Panel item. In this example, {0052D9FC-6764-4D29-A66F-2F3BD9E2BB40} is the GUID of the Control Panel item.

Step 2:

Using the GUID as a name, add a subkey to the registry as follows.

HKEY_LOCAL_MACHINE    

SOFTWARE       

Microsoft         

 Windows              

CurrentVersion                

Explorer                   

ControlPanel                       

NameSpace                          

{0052D9FC-6764-4D29-A66F-2F3BD9E2BB40}                            

(Default) = My Settings

The data for the Default entry is simply the REG_SZ name of the Control Panel item. The Default entry can be useful to identify the GUID entry, but it is optional.

Step 3:

Using the GUID as a name, add a subkey and its entries to the registry as follows.

HKEY_CLASSES_ROOT    CLSID       {0052D9FC-6764-4D29-A66F-2F3BD9E2BB40}          (Default) = My Settings          LocalizedString = @%ProgramFiles%\MyCorp\MyApp.exe,-9          InfoTip = @%ProgramFiles%\MyCorp\MyApp.exe,-5          System.ApplicationName = MyCorporation.MySettings          System.ControlPanel.Category = 1,8          System.Software.TasksFileUrl = %ProgramFiles%\MyCorp\MyApp\MyTaskLinks.xml

• Default. REG_SZ. The display name for the Control Panel item.
• LocalizedString. Optional. REG_SZ or REG_EXPAND_SZ. The module name and string table ID of the localized name of the Control Panel item. The format is an "at" sign (@) followed by the name of the .exe or .dll that contains the Multilingual User Interface (MUI) string table. Environment variables can be used as a substitute for a part of the path. The path and file name is followed by a comma (,) and a hyphen (-), followed by the ID in the string table.
  If the module does not have a string table, then this entry can simply be the display name string. If you use only the display name string rather than a string table, the name does not adjust to the current display language.
  
• InfoTip. REG_SZ or REG_EXPAND_SZ. A description of the Control Panel item. This information is shown in an InfoTip that is displayed when the mouse hovers over the item's icon. The syntax is the same as that used for LocalizedString, including the option of simply providing a string rather than a string table reference.
• System.ApplicationName. REG_SZ. The canonical name of the item. The command of form control.exe /name System.ApplicationName opens the item; for example, control.exe /name MyCorporation.MySettings. See Executing Control Panel Items for more information on the use of Control.exe.
• System.ControlPanel.Category. REG_SZ. A value that declares the Control Panel categories where the item appears. Multiple categories are separated by commas. In the case of the example above, the entry specifies that the My Settings item should appear in both the Appearance and Personalization andPrograms categories. See Assigning Control Panel Categories for possible category values.
• System.Software.TasksFileUrl. REG_SZ or REG_EXPAND_SZ. The path of the XML file that defines task links. This can be a direct file path as shown in the example, or an embedded resource specified as a module name and resource ID such as "%ProgramFiles%\MyCorp\MyApp\MyApp.exe,-31".

Step 4:

Under that same GUID subkey, add the following subkey to the registry to provide the path of the file that contains the icon and the resource ID of the image within that file.

HKEY_CLASSES_ROOT     

CLSID      

 {0052D9FC-6764-4D29-A66F-2F3BD9E2BB40}         

 DefaultIcon           

  (Default) = %ProgramFiles%\MyCorp\MyApp.exe,-2

Note that while the syntax is otherwise similar to the LocalizedString and InfoTip entries discussed earlier, no '@' character is used as a prefix in the REG_SZ or REG_EXPAND_SZ entry that specifies the path.

Step 5:

Add the following information to the registry to provide the command that is called by the system when the user opens the Control Panel.

HKEY_CLASSES_ROOT     

CLSID      

 {0052D9FC-6764-4D29-A66F-2F3BD9E2BB40}        

  Shell           

  Open              

  Command              

     (Default) = [REG_EXPAND_SZ] %ProgramFiles%\MyCorp\MyApp.exe /Settings

How to Make Server Controls Browser Compatible Using ASP.NET

Introduction

In modern web development, we need to check the browser compatibility for our web pages. This can include changing the css styles for design issues. Using ASP.NET we can check the browser compatibility without writing a single line of code for the server controls.

Let's check out some code samples:
If we will define css classes like:
.IEStyle{color:Red;}
.FFStyle{color:Blue;}
.DefaultStyle{color:Black;}

Create a Label control in your page.
Label control:

<asp:Label ID="lblTest" runat="server" ie:CssClass="IEStyle"

mozilla:CssClass="FFStyle" CssClass="DefaultStyle" ie:Text="You are in Internet 

explorer." mozilla:Text="You are in Firefox." Text="You are in other browser." 

/>

Getting started with MongoDB

First download the MongoDB binaries from the following site - http://www.mongodb.org/downloads and unzip the downloaded binaries to a folder of your choice. Now you have to create a folder where MongoDB can store the data. This won't be created automatically.

Execute the following command in your shell:

C:\> mkdir \data

C:\> mkdir \data\db

At the last step, lets run MongoDB. Navigate to your MongoDB folder and execute the mongod.exe:

C:\> cd \my_mongo_dir\bin

C:\my_mongo_dir\bin>mongod

Now we are ready to start. If you want to open the shell admin console, use the following command:

C:\my_mongo_dir\bin>mongo

You can also use the web-based admin console - http://localhost:28017/

A detailed guide can be find on the following site -http://www.mongodb.org/display/DOCS/Quickstart+Windows
