Types of VFabric-GemFire Configurations

This post is to talk about types of configurations.
How to configure distributed system and cache properties for your vFabric GemFire installation.
For your applications, it provides guidance for writing code to manage your cache and distributed system connection, data regions, and data entries, including custom classes.

• Distributed System and Cache Configuration
  To work with your vFabric GemFire applications, you use a combination of configuration files and application code.

1. Distributed System Members
   Distributed system members are programs that connect to a vFabric GemFire distributed system. You configure members to belong to a single distributed system, and you can optionally configure them to be clients or servers to members in other distributed systems, and to communicate with other distributed systems.
2. Options for Configuring the Distributed System
   GemFire provides a default distributed system configuration, for out-of-the-box systems. To use non-default configurations and to fine-tune your member communication, you will customize your system configuration. You can use a mix of various options for customizing your distributed system configuration.
3. Options for Configuring the Cache and Data Regions
   To populate your vFabric GemFire cache and fine-tune its storage and distribution behavior, you need to define cached data regions and provide custom configuration for the cache and regions.
4. Local and Remote Membership and Caching
   For many vFabric GemFire discussions, you need to understand the difference between local and remote membership and caching.

• Cache Management
  The vFabric GemFire cache is the entry point to GemFire caching management. GemFire provides different APIs and XML configuration models to support the behaviors of different members.

1. Introduction to Cache Management
   The cache provides in-memory storage and management for your data.
2. Managing a Peer or Server Cache
   You start your peer or server cache using a combination of XML declarations and API calls. Close the cache when you are done.
3. Managing a Client Cache
   You have several options for client cache configuration. Start your client cache using a combination of XML declarations and API calls. Close the client cache when you are done.
4. Managing a Cache in a Secure System
   When you create your cache in a secure system, you provide credentials to the connection process for authentication by already-running, secure members. Clients connect to secure servers. Peers are authenticated by secure locators or peer members.
5. Managing Region Services for Multiple Secure Users
   In a secure system, you can create clients with multiple, secure connections to the servers from each client. The most common use case is a GemFire client embedded in an application server that supports data requests from many users. Each user may be authorized to access a subset of data on the servers. For example, customer users may be allowed to see and update only their own orders and shipments.
6. Launching an Application after Initializing the Cache
   You can specify a callback application that is launched after the cache initialization.

• Data Regions
  The region is the core building block of the vFabric GemFire distributed system. All cached data is organized into data regions and you do all of your data puts, gets, and querying activities against them.

1. Data Region Management
   GemFire provides different APIs and XML configuration models to support configuration and management of your data regions.
2. Creating a Region with gfsh
   A simple and fast way to create a data region in the vFabric GemFire cache is to use the gfsh command-line tool.
3. Creating a Region Through the cache.xml File
   A common way to create a data region in the vFabric GemFire cache is through cache.xml declarations.
4. Creating a Region Through the API
   You can use the GemFire caching API to create regions in your cache after startup. For run-time region creation, you need to use the API.
5. Region Naming
   To get the full range of vFabric GemFire capabilities for your cached data regions, follow Gem Fire's region naming guidelines.
6. Region Shortcuts and Custom Named Region Attributes
   GemFire provides region shortcut settings, with preset region configurations for the most common region types. For the easiest configuration, start with a shortcut setting and customize as needed. You can also store your own custom configurations in the cache for use by multiple regions.
7. Storing and Retrieving Region Shortcuts and Custom Named Region Attributes
   Use these examples to get started with GemFire region shortcuts.
8. Managing Region Attributes
   Use region attributes to fine-tune the region configuration provided by the region shortcut settings.
9. Creating Custom Attributes for Regions and Entries
   Use custom attributes to store information related to your region or its entries in your cache. These attributes are only visible to the local application and are not distributed.
• Data Entries
  The data entry is the key/value pair where you store your data. You can manage your entries individually and in batches. To use domain objects for your entry values and keys, you need to follow vFabric GemFire requirements for data storage and distribution.
  
  1. Managing Data Entries
     Program your applications to create, modify, and manage your cached data entries.
  2. Requirements for Using Custom Classes in Data Caching
     Follow these guidelines to use custom domain classes for your cached entry keys and values.

Cutting the cable: Wireless charging becomes a reality

Qi standard, emerging technology bringing wireless mobile device charging capabilities to PCs, furniture and cars

Imagine sitting down at work, plopping a mobile device on the desk and having it wirelessly charge itself while, at the same time, synchronizing new data to your PC.

In that world, one could also wirelessly charge a phone set on a car's dashboard or armrest while it plays music through the speakers, and never have to search for the one open electrical outlet at the coffee shop or airport.

That world may not be too far off for the masses of smartphone, tablet and other mobile device users.

With the launch of the Windows Phone 8-based Lumia 920 smartphone last week, embedded wireless charging is hitting the U.S. mainstream.

The built-in wireless charging capabilities offered in the Nokia 920 doesn't require that widgets be plugged into the USB port of a smartphone in order to charge it from a magnetic induction power pad. That's the typical wireless charging process today.

The Lumia 920 only has to be laid on a power pad to be charged.

Charging Pads

William Stofega, an IDC mobile device analyst, said wireless charging pad business is currently dominated by Duracell's Powermat technology, which is based on magnetic induction technology, one of two forms of wireless charging.

Duracell's Powermat wireless phone charger

But that choice is likely to change soon, thanks in part to the Wireless Power Consortium's Qi (pronounced "chee") open wireless charging standard, Stofega said.

Already, some products from 120 companies are certified as compliant with the Qi standard.

The certified products run the gamut, from the LG Optimus LTE2 andPanasonic Eluga smartphones, to charging pads, gaming controllers, Blu-ray Disc recorders, smartphone docking speakers, automobile phone chargers, alarm clocks, battery packs and charging modules that can be installed in tabletops and furniture.

Magnetic induction vs. resonance charging

Analysts note, though, that there are some slight differences in the Qi-compliant wireless charging products being developed today.

Some use magnetic induction charging techniques, which require that the mobile device be in contact with a charging device. Others use resonance charging, which allows a mobile device to be placed near the power source for charging.

Magnetic induction charging uses two coils: a transmitter coil and a receiver coil. Alternating current in the transmitter coil generates a magnetic field, which induces a voltage in the receiver coil.

In contrast, resonance charging offers wireless AC transmission to a device at a distance ranging from 5mm to 40 millimeters (about 1.5-in) from the power source.

Resonance charging is based on the same transmitter/receiver coil technology as magnetic induction, but it transmits the power at a greater distance. So, for example, a mobile device could be charged when laid next to a laptop with resonance charging capability.

To date, there are no resonance-charging devices available, according to Stofega. But that may soon change as Intel ramps up its wireless chip development.

Intel Labs first demonstrated in 2008 technology that could wirelessly charge mobile devices. Intel's Wireless Charging Technology (WCT) would let a user charge a smartphone wirelessly from a notebook PC. Intel late last monthannounced a partnership with Integrated Device Technology Corp. (IDT) to develop chipsets for WCT products.

Products using the chipsets are expected to come out in 2013, Intel said.

Some reports have said the next Apple MacBook laptop will have wireless charging capability based on the Intel-IDT technology.

"[The jointly developed] product is important and new because it leads to a solution that isn't limited to inductive charging and 'smartphone on a charging mat' usage," Intel spokesman Dan Snyder wrote in a blog post.

"Although we are not yet giving out timeframes for consumer products with WCT enabled, IDT has stated they will be delivering their full chipset solution for reference design work in early 2013," Snyder added. "The ecosystem is already excited about this technology so we assume there will be a race to the finish line for sure."

Currently, wireless chargers can supply up to 5 watts of power, the equivalent of most USB-style chargers available today. By comparison, a USB port on a laptop, which shares it's bandwidth with data I/O, offers only 2.5 watts of power.

Some of the latest USB chargers, however, offer fast charging with 10 watts of power.

The Wireless Power Consortium is already working to extend its Qi specification to allow 10 watt power charging, said Menno Treffers, chairman of WPC.

"In the U.S., you're seeing smartphones [with wireless charging] taking off this quarter," Treffers said. "Europe will be a little later than the U.S."

In Japan, where the wireless charging market is more mature, several companies have put out combination products, where a single system can be used to charge a device while transferring data.

For example, TDK this week released a Bluetooth enabled speaker that also uses magnetic induction to power mobile phones while also playing music stored on them.

TDK's wireless charging speaker

Treffers said automobile manufacturers can be expected to add wireless charging technology to cars.

"The automobile industry needs to start now because there's a long [development] lead time," Treffers said. "If you want wireless charging in your car this year, you would have had to have started production last year."

The Qi standard

The Qi symbol that will appear on products

The Wireless Power Consortium published the version 1.1 of the Qi open wireless charging standard in March, 2012.

 

Laptops and charging devices supporting the standard can charge mobile devices that are placed on, or near them using either magnetic induction or resonance charging.

According to WPC, there are 8.5 million Qi capable devices sold worldwide. The largest market for wireless charging is Japan, where it's almost impossible to purchase a mobile phone without the capability embedded in it, Treffers said.

Gartner analyst Ken Dulaney called the Qi standard "a strong, and sorely needed means for wireless charging."

Though several key vendors, including Apple and Samsung, have yet to announce support for the Qi Standard, Dulaney believes it already has the necessary backing to move forward.

According to Intel, an Ultrabook user could soon simply use WCT detection software on a PC to charge a nearby smartphone. Coupling takes place between the two devices and energy begins to seamlessly and wirelessly flow from the Ultrabook to the smartphone.

"Within an hour, you have recharged your smartphone sufficiently to make it through the afternoon. No more wires or chargers," Intel said.

The Qi specification is also aimed at technology used automotive systems to avoid interference with wireless systems like Bluetooth. The Qi standard also is expected to be adopted by wireless payment systems, combining powering and data transfer.

"The technology has improved to the point where it takes just about as long to charge your device wirelessly as it does with a cable," Dulaney said. "And combined with Bluetooth you really could see a day where you could give up the cables in your bag."

Remove Windows 8 from a dual-boot configuration

 

Thanks to Greg Shultz.

In the last couple of blog posts, I’ve shown you how to set up Windows 7 and Windows 8 Release Preview in a dual-boot configuration. In Dual-boot Windows 7 and Windows 8, I showed you how to set up a dual-boot configuration by repartitioning your hard disk. In Dual-boot Windows 7 and Windows 8 using a VHD, I showed you how to set up a dual-boot configuration by using a VHD (Virtual Hard Disk), which can only be done in Windows 7 Ultimate or Windows 7 Enterprise.

At some point in time before October 26, 2012, you’ll need to stop using the Windows 8 Release Preview as it will stop working. Not exactly sure what will happen, but if it is like most of Microsoft’s free evaluations, one or all of the following will occur: the desktop background will turn black and you will see a notification indicating that the system is not genuine, or the PC will automatically shut down every hour without allowing you to save any work in progress. As such, you’re going to want to remove Windows 8 Release Preview from your system.

In this article, I’ll show you how to remove Windows 8 from a dual-boot configuration. As I do, I’ll show you how to remove it from both the partition and the VHD methods.

This blog post is also available in the slideshow format in a TechRepublic Photo Gallery.

Be safe

Removing Windows 8 from a dual-boot configuration should be a relatively straightforward operation; however, just to be on the safe side, I strongly recommend that you back up your data files before you proceed. If you followed my instructions in the earlier dual-boot articles, you should already a complete image of your hard disk via the System Image tool. Even so, having a current backup of any data files will ensure that nothing will be lost if anything out of the ordinary were to occur as you follow the steps for removing Windows 8 from a dual-boot configuration.

Removing Windows 8 from the boot loader

You’ll remove Windows 8 from the boot loader from within Windows 7. So the first thing you will do is boot into Windows 7.

As you may know, Windows Vista, 7 and 8 use what is known as the boot loader architecture in order to boot up the operating system. In a nutshell, the boot loader architecture consists of the Boot Configuration Data database and three components:

The Windows Boot Manager (Bootmgr.exe)
The Windows operating system loader (Winload.exe), and
The Windows resume loader (Winresume.exe)

When you set up a dual-boot configuration by installing Windows 8 into an existing Windows 7 configuration, the installation procedure creates the boot menu by adding entries to the Boot Configuration Data database. Now, as the computer boots up, the Windows Boot Manager loads first and reads the Boot Configuration Data and uses the information it finds in the database to display the boot menu. When a selection is made, the Windows Boot Manager retrieves information about how to boot that operating system and then passes the information over to the appropriate Windows operating system loader or Windows resume loader, as the case may be.

As a part of this boot loader architecture, Windows provides you with a command line tool called the Boot Configuration Data Store Editor (BCDEdit.exe), which you can use to view and edit the Boot Configuration Data database. Now, since all we will be doing is removing Windows 8 from the menu, we can just use the System Configuration tool. It’s much easier than using Boot Configuration Data Store Editor to perform the removal operation.

BCDEdit

Even though we will use the System Configuration tool to remove Windows 8 from the boot loader, for educational purposes, let’s take a moment to use Boot Configuration Data Store Editor just to take a peek at the boot menu in the Boot Configuration Data database.

You need to launch BCDEdit.exe from a Command Prompt with Administrator privileges. To do so, click the Start button and type cmd in the Start search box. When you see CMD appear the results pane, right click on it and select the Run as Administrator command. When you do, you will encounter a UAC and will have to work through it. Once the Administrator Command Prompt appears, just type bcdedit and press [Enter]. You’ll then see the commands that make up the boot menu in the Boot Configuration Data database.

In Figure A, you’ll see the boot menu for a Windows 8 VHD. As you can see, the instructions in the Windows 8 section of the menu specify the Windows8RP VHD file as the device to boot from.

Figure A

This is a boot menu for dual-booting Windows 8 from a VHD.

In Figure B, you see the boot menu for a Windows 8 partition. As you can see, the instructions in the Windows 8 section of the menu specify the F: partition as the device to boot from.

Figure B

This is a boot menu for dual-booting Windows 8 from a partition.

At this point, go ahead and close Administrator Command Prompt window.

System Configuration

As I mentioned, the easiest way to remove Windows 8 from the menu is to use the System Configuration tool. To launch the System Configuration tool, click the Start button, and typemsconfig in the Start search box. When you see msconfig appear at the top of the results pane, just press [Enter]. When the System Configuration window appears, select the Boot tab and you’ll see that Windows 8 is listed as the Default OS and that Windows 7 is listed as the Current OS, as shown in Figure C.

Figure C

You can easily remove Windows 8 from the boot loader using the System Configuration tool.

The first thing that you need to do is make Windows 7 the Default OS. To do so, select the Windows 7 entry and click the Set as default button. When you do, you’ll see that Windows 7 is listed as both the Current OS and the Default OS. To continue, select the Windows 8 entry, as shown in Figure D, and then click the Delete button.

Figure D

Once you select the Windows 8 entry, just click the Delete button.

As soon as you do, the Windows 8 entry will be removed. When you click OK, you’ll be prompted to restart your computer, as shown in Figure E. Just click the Restart button.

Figure E

You’ll be prompted to restart your computer after deleting the Windows 8 entry.

When your system restarts, it will boot right into Windows 7 - you will not see a menu. If you wish, you can re-open the Administrator Command Prompt, type bcdedit, press [Enter], and you’ll see that the commands for Windows 8 are no longer on the Boot Configuration Data database’s boot menu, as shown in Figure F.

Figure F

The Windows 8 section will not appear on the Boot Configuration Data database’s boot menu.

Removing the partition

To remove the Windows 8 partition and reallocate the disk space, you’ll use the Disk Management tool. To begin, click the Start button, type Disk Management in the Search box, and press [Enter] when Create and format hard disk partitions appears in the result pane.  When Disk Management launches, right click on the Windows 8 partition and select the Delete Volume command, as shown in Figure G.

Figure G

Right click on the Windows 8 partition and select the Delete Volume command.

When you do, Disk Management will prompt you twice to confirm the Delete Volume operation, as shown in Figure H. At this point, you’ll see that the area is now marked as Free space. If at a later date you want to install the real version of Windows 8, you can leave the space as it is.

Figure H

You’ll see two prompts before Disk Management will delete the volume.

However, if you want to regain the space, you’ll right-click on the Free space and select the Delete Partition command. When you do, Disk Management will prompt you to confirm the Delete Partition operation, as shown in Figure I.

Figure I

If you want to regain the space, right-click on the Free space and select the Delete Partition command.

Once the partition has been deleted, right-click your Windows 7 partition and select the Extend Volume command, as shown in Figure J. When you do, the Extend Volume Wizard will launch.

Figure J

Use the Extend Volume command to launch the Extend Volume Wizard.

The Extend Volume Wizard consists of three screens, which are shown in Figure K. The second screen will be filled in for you and in most cases you will just go with the default settings.

Figure K

The Extend Volume Wizard consists of three screens and in most cases you will just go with the default settings.

Once the volume has been extended, you’ll see that all of the free space has been reallocated to your primary hard disk, as shown in Figure L.

Figure L

You should be right back where you started.

Deleting the VHD

If you installed Windows 8 to a bootable VHD in either Windows 7 Ultimate or Windows 7 Enterprise, all you have to do is locate the VHD file and delete it as shown in Figure M.

Figure M

You can just delete the VHD file.

How to Get Aadhar Card Anywhere in India/ Information on Aadhar Enrollment/Application Form, Procedure, Checking Status

With the mission of providing each and every resident of India a unique identification the ambitious project of UIDAI (Unique Identification Authority of India) was set in February 2009 with its chairman being former IT czar Nandan Nilekani.

The association of Mr. Nandan is very important in this project as the government wanted to send the right message upfront that they are very serious about the project, and also it required a visionary leader such as him who is well-versed with the overall Information Technology scenario, which is an essential part of collecting and safely storing information of more than a billion citizens.

To be frank, India is far too late in the scene of providing unique ID's to all of its citizen. Countries like Belgium, Bulgaria, and Turkey have made it compulsory for their citizens to get the National Identification numbers at birth. Parents must get their National IDs for their children immediately after their birth.

Whereas in United States to some extent the Social Security Number can be associated with the national identities. SSN is not compulsory but over the years for all banking and taxation purposes SSN's are mandatory. So, in a way it can be dubbed as unique identity in United States.

There are some what 63 other nations in the world where some kind of UID's are already in place and more and more countries through out the world are starting to issue some kind of national identities to their citizens and for India it is a clear case of better late than never.

The closest our government came to provide a unique ID to every citizen is the PAN card number which every citizen can apply for unlike the Voter ID card which can only be applied when one reaches the age of 18. But we all know how much bad is the status of PAN cards; we constantly hear about various scams or where people can easily get more than one PAN number for them.

First of its Kind in the World

It is true that several other countries have some or the other national identity number but no other country in the world has ever started such an operation which with the ambition of enrolling more than a billion individuals. Each and every individual will get a 12-digit unique ID number which will be helpful for any citizen to easily migrate to other places without worrying to get fresh or to renew existing identities.

It will also be a first of its kind in a way because that it will store biometric and demographic data of the applicant, which will involve iris and fingerprint scan and photograph. No other country in the world has sought to collect both the iris and fingerprint of its citizens.

Collection of all this data will be done with top-quality modern tech devices and the data will be stored in an economical way in a centralized location so that agencies from the government as well as private agencies can get the information accessed. But only a "Yes" or "No"; it won't provide each and every information of you to be exploited.

Also, never before any government in the world has ever spent such amount of money or is planning to spent such huge amounts of money. At the time of writing a total of 2000 Crore rupees has been allotted to the agency for its operation. According to various reports the project could cost anywhere between 7 billion to 33 billion rupees.

Aadhar Information From the Official Site

Sr. No.

What Aadhar is?

What Aadhar is not?

1

A 12 Digit Number

Just Another Card

2

It is for Every Individual, Including Infants

One Per Family

3

Enables identification, and is for every resident

Establishes citizenship and is only for Indians

4

Will collect demographic and biometric information to establish uniqueness of individual

Will collect profiling information such as caste, religion, language

5

Voluntary

Mandatory

6

For every resident, irrespective of existing documentation

Only for individuals who posseses identification documents

7

Eah individual will be given a single unique ID number

Indiviual can obtain multiple Aadhar

8

UIDAI will enable a universal identity infrastructure that any ID based application like ration card, passport etc. can use

Aadhar's will replace all other IDs

9

UIDAI will give a "Yes" or "No" response for any identification authentication requires

UIDAI information will be accessible to public and private agencies

Explanation of the Above Table

It is not just another card for a specific purpose. In the larger context it can be used in the future for many purposes.
Aadhar can be applied for every one; even for a new born baby or for a 90 year old person. For children below the age of 5 there won't be collection of any biometric information such as iris or fingerprint scan. Their UID will be linked with their parents UID and once they turn 5 they will have to update their ID's with biometric information. Biometrics will have to be updated once again when they turn 15. As for differently abled people who cannot provide their biometric information their will be other markers that will be used instead of biometric information.
It is not like other cards where the holder of the card is a citizen of India, it is for every resident whether he may be an Indian or foreigner (though for foreigners they have still not started to issue cards).
It won't collect your information related to your caste etc. But it will collect your biometric and demographic data.
UID's are not mandatory and it is not necessary for every individual to have it. But as experts suggest that invariably it will be required by many government and private agencies in the time to come. So, it is better that you get enrolled.
Yes, it is for every individual irrespective of their existing documentation. That is, if a person does not have any previous documentation then he/she can also get their Aadhar. (For more information on this see the 2nd point of "How to Get Aadhar Card Anywhere in India" section on this page).
Each and every individual is allowed to get only one Aadhar card or so as to say that he/she will not be able to get more than one UID. This is particularly true because it records the biometric information of the applicants. So, getting a fake Aadhar card is next to impossible until we come across a big scam.
It is a general misconception that in the times to come UID will replace all other ID's that we use now. It will just make easier for people to get their unique identification anywhere in India. Aadhar cards won't replace your driver's license nor it will render your Voter ID useless.
The information that you will share will not be available to use by government agencies or private agencies to profile you instead it will just provide a cursory yes or no identification. That is your information will not be available for use of others.

How to Get Aadhar Card Anywhere in India

Every resident will have a Aadhar card with a unique number, a 12 digit number which will serve its holder a proof of identity and proof of address all over India.

The 12-digit number displayed on it is your unique ID number which in the system will be a 16-digit number with four digits as a prefix digit. The rest four digit will not be displayed on your card and it is only for the usage of the database and the servers.

1) Any resident can walk in to the nearest enrollment center and get themselves enrolled for an Aadhar card. Nearly every city or town will have an enrollment center or most probably the nearest major town or village will have an enrollment center.

2) Walk-in with your identity proof for address (PoA) and proof of identity (PoI) documents.

Even if you don't have any other identification then also you can get the card by one or the other method mentioned below:

The UIDAI has in place a system called Indroducer System.

If the head of your family has any documentation then he/she can first enroll and then after getting their card he/she can introduce you as a family member.

The second method is where a introducer who is appointed by the registrars or directly by the authority can introduce people who don't have such identification documents. This is specifically helpful for poor people who until now didn't had any such documents. There is a large section of people in remote areas where people don't even can produce a proof of address or proof of identity. This system is primarily helpful for those.

Changing or Correcting Information From Your Aadhar Card

So, you got your Aadhar card and found that there are some changes required. Or another scenario can be that you have changed your address or are planning to relocate somewhere else. Or for some other reasons you want to change some other information, there can be 'n' number of reasons.

As the process is totally done electronically and you yourself (or some other person on your behalf) have to verify the information entered at the time of enrollment, after which the information is only verified centrally and your card may be either be issued or it may get rejected (which is rare if you have correct documents).

So the chances are that your card was issued correctly but now as circumstances have changed and you would like to get your card edited or corrected. Then this may not be a good news for you because there is still not a process in place to get information in your card edited or changed.

The UIDAI is constantly evolving the whole process and there will soon be a process by which you will be able make corrections in your card but also can view your own information in real-time. At this point in time there is no such procedure where you can change or edit your information in the card.
