VMware Horizon Suite brings virtual desktop into post-PC era

New offering addresses BYOD headaches by giving users secure, consistent access to apps and data from any device

At VMworld today, VMware offered a peek at its forthcoming VMware Horizon Suite, a technology bundle designed to provide mobile users secure, consistent, 24/7 access to their desktop, applications, and data from any device. Complementing the announcement, company execs talked up the fruits of the Wanova Mirage acquisition, which VMware said extends the VMware View VDI platform to cloud applications.

The Horizon Suite represents the second comprehensive bundle VMware has rolled out at VMworld; the first was the all-encompassing vCloud Suite 5.1 unveiled yesterday. VMware's Horizon vision is ambitious and a seeming panacea to BYOD-induced headaches. To the company's credit, it has been baking the components into the suite for some time now, and the company knows its way around a virtualized desktop.

Currently an alpha release, the VMware Horizon Suite aims to equip IT with the tools to customize a service catalog for all company data and applications. The suite can recognize user attributes and environment, such as what device type, location, and connectivity, and enforce appropriate policies across applications, data, and desktops, according to VMware, which posted a video of the suite in action.

"The dramatic influx of mobile devices and applications is quickly subverting existing IT policy and management," said Brett Waldman, a senior research analyst at IDC. "Modern solutions will need to have an integrated approach that holistically manages users, applications, and devices to satisfy radically changing requirements to be well accepted by today's IT organizations."

The suite unites five VMware-branded tools into an integrated management platform: Project Octopus, Project AppBlast, ThinApp, VMware Horizon Application Manager, and VMware Horizon Mobile.

Released in beta last May, Project Octopus lets end-users securely connect, share data, and collaborate with one another regardless of device. IT administrators, meanwhile, have the ability to govern usage and set policies for data access and sharing, both within the organization and with external contributors.

Project AppBlast, announced in September 2011, provides fully interactive, remote access to desktop apps such as Microsoft Office view a Web browser.

ThinApp (formerly known as Thinstall) lets organizations package applications into single executables that run in isolation of one another and from the OS. Application packages can be deployed to different Windows platforms for easy migration.

VMware Horizon Application Manager, first unveiled at last year's VMworld, is a cross-platform management solution designed to unify, secure, and control access to SaaS, Web, and Windows applications from end-user devices. The software provides a central location for applying application policies, including how, when, and to whom end-user apps are provided. It also provides a cloud identity service layer for securing managed access to Windows, SaaS, and Web-based applications.

Application Manager also includes an IAM (identity-and-access-management) technology that helps IT extend user profiles securely into the cloud.

Finally, VMware Horizon Mobile is based on the VMware MVP (Mobile Virtualization Platform), and it enables organizations to establish and securely manage an employee's connected mobile workspace in isolation from their personal mobile environment.

As for Wanova Mirage, the software is capable of cloning endpoint images in the data center and running them locally on physical devices. The goal here is to provide users with a consistent PC experience, regardless of device, while giving admins a centralized location to manage it all. VMworld execs demonstrated how a user's desktop OS could be upgraded within moments from Windows XP to Windows 7 while retaining the same desktop appearance and files. They went on to show how that desktop image could be quickly accessed from a MacBook.

Low power server packs 64 Xeon processors

SeaMicro says it has packed 64 Intel Xeon processors into a device it says "uses half the power, takes one-third the space, and delivers twelve times the bandwidth of today's best-in-class servers." The SM10000-XE has up to 2 terabytes of DDR3 memory, up to 64 SATA hard disks or solid state drives (SSDs), and up to 16 10 gigabit Ethernet (10GbE) or 64 1GbE ports, the company says.
We last looked at "power-saving" servers last November, when Calxeda announced its ARM-based ECX-1000 "server-on-a-chip" and HP said it would use the processor in "Redstone Server Development Platform" products during the first half of 2012. Given that there's no ARM-ready version of Windows Server software, the HP devices will run Linux -- most likely Canonical's Ubuntu, it was reported at the time.

Best comptia A+ Training, Comptia A+ Certification at Certkingdom.com

Intel and Sunnyvale, Calif.-based SeaMicro counter that it's possible to trim the power diet of Windows-ready x86 servers too, thanks to newly designed processors and architectures. Last March, the chipmaker announced four new CPUs intended for the "micro server" market, including the Xeon E3-1260L (four cores, 2.4GHz basic clock speed, 3.3GHz clock speed, 8MB L3 cache, 45-Watt TDP).

Also in 2011, SeaMicro unveiled a pair of servers that are 10U high (17.5 inches), 19 inches wide, and 30 inches deep -- each containing 64 separate processor cards. The cards are said to be linked by a backplane known as the "Freedom Supercomputer Fabric," with a claimed capacity of 1.28Tb/sec.

Sea Micro's new SM10000-XE looks externally identical to its Atom-powered siblings
(Click to enlarge)

The original SM10000-64 offered four dual-core Atom N570 (dual-core, 1.66GHz) chips per processor card, for a total of 256 CPUs. The SM10000-64 HD, announced in July, increased the density to six N570s per card, for a total of 384.

Now, with the new SM10000-XE, SeaMicro has upgraded the processor cards yet again, placing a single Xeon E3-1260L on each in place of the multiple Atoms. Though the total number of threads becomes eight instead of the twelve that a SM10000-64 HD card provide, overall computing power is better, the company says.

The SM10000-XE contains 64 of these Xeon-based CPU cards

According to SeaMicro, the overall power consumption of the SM10000-XE is comparable to the SM10000-64 HD, at 3500 Watts. Each card accepts up to 32GB of error-correcting DDR3 memory, for a total capacity of as much as 2 TB; meanwhile, it's possible to jam as many as 64 2.5-inch hard disks or SSDs into the system, adds the company.

Like its Atom-powered siblings, the SM100000-XE includes redundant power supplies, multiple fans, integrated load balancing, and a terminal server. The server supports up to eight Ethernet cards in all, SeaMicro says: either 1GbE cards with eight interfaces apiece, or 10GbE cards with two interfaces each.

Andrew Feldman, CEO of SeaMicro, stated, "The addition of the SM10000-XE to the SM10000 family allows one architecture to support big and small processors -- enabling customers to match their workload to the processor best suited for that work. The SeaMicro SM10000 family delivers a single architecture capable of supporting different processor types, each optimized for a different type of work."

Microsoft: Windows 8 beta should be compelling for enterprises

When Windows 8's beta version becomes available for download on Wednesday, Microsoft expects many enterprises to jump at the chance to give the new operating system a test drive, but some industry analysts doubt that there will be much interest among corporate IT officials.

Best comptia A+ Training, Comptia A+ Certification at examkingdom.com

Most organizations are focused on Windows 7, whether they have already implemented it, are in the midst of rolling it out, or are still planning its adoption, so it's unlikely that IT departments will give Windows 8 a serious look at this point, analysts said.

However, Microsoft is betting otherwise, confident that Windows 8 packs enough enterprise IT features and functionality that IT officials will find attractive and compelling.

"The important thing when we think about Windows 8 in a business environment is how we've thought about reimagining Windows and the value it can bring to our end users," said Erwin Visser, a Senior Director for Windows at Microsoft. "The context here is that the world of work has changed dramatically over the last years."

Microsoft will officially announce and release the Windows 8 beta at an event in Barcelona, Spain, where the mammoth Mobile World Congress conference is taking place. The Windows 8 beta available on Wednesday will run on machines with x86/64 chips from Intel and AMD.

Earlier this month, Microsoft said that around this time it will also distribute to hand-picked developers and hardware partners a test version of Windows 8 for devices with ARM chips, called WOA, loaded on test PCs.

In recent months, Microsoft has been meeting with enterprise customers to discuss Windows 8, and has found them very interested in the operating system's features for tablet devices in particular, he said. Unfortunately, Microsoft wasn't able to provide any of those customers as references for press interviews at this point.

"One big point of feedback from our customers is how we can help them make their end users more mobile, and give them access to corporate resources from home, from mobile scenarios like a coffee shop, on the road," Visser said.

Indeed, Windows 8 has been designed from scratch for "touch centric" devices, namely tablets, which, thanks to the popularity of Apple's iPad, have not only taken the consumer market by storm but have also invaded workplaces as part of the "bring your own device to work" trend.

Analysts agree that Windows 8 will be very compelling for enterprises eager to roll out properly configured tablets to their employees, to cut down on the often chaotic and unsafe practice of having them use their personal tablets at work. However, it's unlikely that Windows 8 will be broadly deployed across corporate desktops any time soon, they said.

"Is Windows 8 going to be attractive to enterprises? The answer in the short term is: probably not," said Al Gillen, an IDC analyst. "Enterprises tend to be conservative about their deployments and a new Microsoft product coming out the door that has a lot of improvements and changes represents a source of potential problems."

"When this product launches, enterprises that are currently deploying Windows 7 are unlikely to stop and begin deploying Windows 8," he added.

Gartner estimates that in developed countries Windows 7, which began shipping in October 2009, has been fully implemented in about 10 percent of enterprises, while 55 percent are in the process of deploying it and 25 percent are just starting, said Michael Silver, a Gartner analyst. The remaining 10 percent have barely looked at it.

Except for those planning to roll out tablets, most organizations will skip Windows 8 entirely, Silver predicts. "Most organizations haven't yet migrated from Windows XP. They're in the midst of their Windows 7 deployments and they need to stay the course and maybe even accelerate their Windows 7 deployments," he said.

"We don't see that many organizations that are just finished with their Windows 7 deployments will look at Windows 8 and say: 'Yes, lets do it again,'" Silver added.

As of Dec. 31 of last year, more than 525 million Windows 7 licenses had been sold since its launch, and it had been installed in about one-third of enterprise desktops worldwide.

According to Visser, the last thing Microsoft would want is for any enterprise engaged in deploying Windows 7 to stop on its tracks after testing Windows 8. "Our message to enterprises is that it's important for them to continue their Windows 7 deployments because those investments will carry forward to Windows 8," he said.

Microsoft hasn't said when it plans to ship Windows 8, but IDC's Gillen believes that the company will try hard to have it ready in time for this year's holiday season, loaded in new consumer PCs and tablets. "There's a fair amount of pressure on Microsoft not to miss the holiday shopping season," Gillen said.

Indeed, during Microsoft's second fiscal quarter, ended Dec. 31, revenue at the Windows & Windows Live division shrank 6 percent to $4.74 billion, hurt in particular by a slowdown in consumer PC sales.

The success of Windows 8 has serious implications for Microsoft. "Windows 8 is perhaps the most critical release of Windows we've had probably back to as far as Windows 2000 Professional or even Windows 95," Gillen said. "I see this as being so fundamentally important."

While Windows is entrenched and dominant in PCs, it is a minor player in tablets, a critical market in which Microsoft has to solidify its position. "Whether Windows 8 is great or not doesn't necessarily change Microsoft's position in the PC space. But if Windows doesn't become competitive in tablets, it leaves Microsoft in a very vulnerable position," he said. "It's absolutely critical for Windows 8 to be successful in tablets."

Gartner's Silver expects Windows 8 to do much better commercially right out of the gate in the consumer market, which welcomes, and even encourages, more frequent operating system releases than the enterprise.

Still, Visser makes a case for strong interest in Windows 8 by IT departments as well, listing features like Windows To Go, which lets users boot and run Windows 8 from USB devices like flash drives, and the new, much trumpeted Metro UI, designed with touch screens in mind.

IT officials will also be interested in Windows 8's new features which simplify the way end users manage their connections to Wi-Fi and mobile broadband networks, as well as in its virtual desktop infrastructure (VDI) improvements, he said. In addition, Windows 8 also features security enhancements, such as a new secure boot process.

These and other enterprise IT features represent a compelling case for IT professionals to start looking at Windows 8 and try out the beta, to see how the finished operating system eventually will offer their organizations business value, Visser said.

Gartner's Silver, however, thinks Windows 8 may share the fate of Windows Vista, which enterprises largely bypassed.

"Some of those Windows 8 features will be compelling for organizations, but the question is: Will they be compelling enough for organizations to go back into that project and re-do a bunch of desktops again? For most organizations we think the answer will be: no," Silver said.

"It's possible some organizations may decide to deploy Windows 8 on new machines that come in but I wouldn't really expect that to happen much before the beginning of 2015 and by then we'll probably be looking at Windows 9 around the corner," he added.

Using VXML Tools to Design Software

Most people think that interactive dialogue between human and computer is impossible, but by using voice recognition and VXML applications, this becomes possible, and the results are amazing. VoiceXML applications are used extensively in numerous call centres throughout the world, and specific VXML tools are used to personalise each application to suit the need of each client. The automated phone systems that use this have numerous roles, including, but not limited to, package information, order information, notifications and alarms. IVR technology is used alongside it, to provide interactive voice responses to the requests of users.
It may sound extremely complicated, but it is not, and using such systems properly can truly save a lot of time and manpower. To cater to the needs of different customers, different companies have developed their own software and VXML tools. Most offer graphical interfaces that make them extremely easy to use, and most also offer top level maintenance to go along.

Microsoft Commptia A+ Training , Comptia A+ Certification and over 2000+
Exams with Life Time Access Membership at http://www.actualkey.com

However, some companies go even further, and they offer the tools needed for each company to develop their very own VXML tools and applications. The good part is that no programming skills are required for this, as these also have a graphical interface and use a simple drag and drop method. Companies can use this to create applications tailored to their specific needs, without needing to hire a programmer.
It is well known that developing any application takes considerable financial effort, not to mention the extended period of time that developing a good application requires. By having a graphical interface and clear instructions on how to use the software, companies can save a lot of resources and can have their application ready much faster than expected.
Some may think that applications developed using this will lack the capabilities of professional applications, and that they are nothing more than cheap versions of the professional ones, but that is wrong. In fact, some of the applications created using such tools, and the backend capabilities added to them, are much better than many professional applications that cost several times more. This also includes applications that could be created by professional programmers not using the tools provided, as besides the time needed for development, testing, and tweaking, there is also the matter of price, and that is much higher that what it would cost to purchase the tools needed to create the software.

More than one application is usually used in large companies, and managing them is not a problem, because there is usually a management console available that can be used to monitor all the applications that are running in the system. This allows managers to keep an eye out on what is happening and what their workers are doing, from their own workstations, without having to move around and check up on everyone.
Time is saved this way as well, and it is easy to see why such solutions are increasing in popularity. Managers are free to handle other issues and problems, as they no longer have to worry about keeping an eye on their workers. They have a complete data log that can be checked at all times to see what was going on, and they are notified immediately of any problems that arise in the system.
Workers also gain several benefits from using such applications, as they make their job easier. The applications created using the VXML tools can handle calls from users and provide the required information without any management. Using IVR technology, user responses are analysed and the software determines what the best course of action is. In case there are any errors in detecting what the user is saying, the software can alert a live consultant who can jump into the call directly. All automated phone systems allow consultants to interrupt a call to provide information on promotional deals, emergency alerts, or other things of similar nature. Offering an extremely reduced development time for applications, without costing a fortune, the tools offered can play a major part in the success of any company. Without any disadvantages and without having to worry about maintenance later on, there is no better solution for the creation of VXML applications designed for a specific purpose.

Follow the Simple Steps to develop the iPhone App and Submit it to App Store

It is not as hard or as simple to develop an iPhone App that one might think. As many people have misconception that iPhone Application development is really very hard, I want to remove this conception and motivate them to go for it by following the steps mentioned in the article below.
“Cooking” up an iPhone application also involves a process similar to Cooking. You can find here the steps which should be followed from head to the bottom i.e. from an app idea to its upload on the iTunes.
It must be clear to you that creating an iPhone app or the iPhone application development is not entirely free; also you will need a Mac at some point and so need to use specific Mac-happy code to develop the application.

Microsoft Commptia A+ Training , Comptia A+ Certification and over 2000+
Exams with Life Time Access Membership at http://www.actualkey.com

Are you excited now? Follow these exhilarating steps:
1. Design a Smart and Unique Idea

Think of a unique idea and craft the design in a way that one want to use your app. Develop the app in a way that people can pay you for that as they will get more in return of their money.

Please cross check about your idea in the app store that there is no app having the same idea. If you found one, go for a better app which already exists.

2. Get a Mac and Register on Apple as an Developer
As the iPhone development tools are available only for Mac Users, so it is necessary to get a Mac to have your app in the App Store. Mac mini will also serve the purpose.

After having a Mac, go for the free registration to become an official Apple Developer by providing them with your details and agreeing to their terms. Only once the registration is needed. After registration, you can develop iPhone apps for any of the Mac products.

3. Download iPhone Software Development Kit (SDK) and XCODE

Now you are an Official Apple Developer, you are allowed to download iPhone SDK. As SDK comes with all types of documents, sample codes and all the other things you might need later. So, the download is HUGE, and so will take a few hours. Do take care of its version, as it depends on the OS you are using.

As per Apple, “XCode is a complete, full-featured IDE built around a smooth workflow that integrates the editing of source code, with the build and compile steps, through to a graphical debugging experience – all without leaving the view of your source code.” So, go for this and download it.

4. Use the Templates in SDK for iPhone Application development
Start designing the app with the templates available in the SDK. In the SDK, you can find lot of templates to choose one from and also have great You tube clip tutorials to tell you how to use these templates effectively.
5. Program your App using Objective-C

Understand the basics of Objective-C and program your app. You can take screenshots as you precede that helps you remember what you tried. Time required by the apps totally depends on the app features and the details you want in it.

6. Test the application

Make the full use of the huge download of SDK you have done. SDK comes with a lovely iPhone simulator, load your app in it and test it on the simulator. Use the app in all the possible ways one can use and try to work out as many bugs as you can. Test it completely.

7. Upload the iPhone application on iTunes for Approval

Loading an app into iTunes costs a one time member fee of $99 (USD), and it is must to be paid. There is no way to get away of this amount. But, if your app is worthy, you can earn it back in many folds.

Test your App completely and work on all the issues and then submit for approval. Apple takes few days to approve it so be patient and wait for the response.

Major Symantec breach highlights risks of running old software

Symantec says it has fewer than 50,000 users of pcAnywhere, a remote-access program that has been around for decades. It now says, for safety’s sake, those users should pull the plug. Immediately.

Best comptia A+ Training, Comptia A+ Certification at Certkingdom.com

PCAnywhere was ancient in June 1996, when Symantec shipped pcAnywhere 7.5 for Windows 95 and Windows NT Workstation 4.0. That’s the oldest press release I can find online, and it’s introducing version 7.5. The product already had seven releases at the dawn of the Windows era. And the software industry didn’t run at Internet speed back then.

People are still using versions even older than that. I am pretty sure the MS-DOS version of the remote-access program goes back to the late 1980s. And yet I found a support request on Symantec’s forums from May 2010—less than two years ago—from someone who needed to connect to a computer running MS-DOS 6.22 and PC Anywhere 5.0 for DOS.

This was well into the 21st Century.

pcAnywhere version 12.0 shipped in 2006. It’s had incremental releases since then, but Symantec hasn’t found any of those events important enough to issue a press release.

Let’s paint this picture in stark black and white: This is a six-year-old software program, built on decades of legacy code written in pre-Internet days, that is now in maintenance mode. Or, if you prefer, on life support.

And now Symantec is urging its users to pull the plug, at least temporarily. The company revealed the gory details this morning not in a press release, but in a 10-page white paper (PDF):

Upon investigation of the claims made by Anonymous regarding source code disclosure, Symantec believes that the disclosure was the result of a theft of source code that occurred in 2006. We believe that source code for the 2006-era versions of the following products was exposed: Norton Antivirus Corporate Edition; Norton Internet Security; Norton SystemWorks (Norton Utilities and Norton GoBack); and pcAnywhere.

I wouldn’t be worried about those antivirus and security programs. They have been regularly updated and heavily rearchitected since 2006, with significant upgrades every year. But pcAnywhere has been in maintenance mode, a forgotten product.

Symantec says fewer than 50,000 people are still using pcAnywhere. And now the company says, in no uncertain terms, they should stop:

With this incident pcAnywhere customers have increased risk. Malicious users with access to the source code have an increased ability to identify vulnerabilities and build new exploits. Additionally, customers that are not following general security best practices are susceptible to man-in-the-middle attacks which can reveal authentication and session information. General security best practices include endpoint, network, remote access, and physical security, as well as configuring pcAnywhere in a way that minimizes potential risks.

At this time, Symantec recommends disabling the product until Symantec releases a final set of software updates that resolve currently known vulnerability risks. For customers that require pcAnywhere for business critical purposes, it is recommended that customers understand the current risks, ensure pcAnywhere 12.5 is installed, apply all relevant patches as they are released, and follow the general security best practices discussed herein. [emphasis added]

I am not sure I have ever heard of a company advising its customers to stop using a product completely because it was too dangerous. But apparently the risk with pcAnywhere is so great that this is the only sane option.

There are many, many modern alternatives to allow secure external access to your business network or your home PC. If you’ve been hanging on to pcAnywhere, you’re now officially out of excuses to switch.

Update: Reached for comment, a Symantec spokesperson replied vie e-mail with a statement that repeated, almost word for word, the advice contained in the white-paper advisory. The spokesperson also referred customers to a Symantec site that hosts information on the breach:

Hibernate mode is a power saving feature for computers. In hibernate mode, the current state of a
computer is saved to the hard disk, and the computer shuts down. A user will have to power on
the computer to restore the previous settings. When a computer resumes from hibernate mode, it
reads the saved settings from the disk and restores the system state as it was before it entered
hibernate mode. By default, hibernate mode is disabled. If a computer is not ACPI-enabled or
APM-enabled, users will have to enter hibernate mode manually. Users cannot set the computer
to automatically hibernate after a certain time. With ACPI-enabled and APM-enabled computers,
users are able to set hibernate mode automatically.
The standby mode is a power saving feature for computers. In this mode, a computer does not
shut down completely. The computer goes to low power state and, as a result, it consumes less
power.
When the computer resumes from the standby mode, full power is restored to its devices. During
the standby mode, if the power supply is disconnected or interrupted, data might be lost. The
standby mode is available automatically on ACPI-enabled or APM-enabled computers. Users do
not need to enable this mode manually. This mode is not available in non-ACPI and non-APM
based computers.
Answer option A is incorrect. Hot plugging is a feature in which a device can be installed or
removed while the computer is running.

technology for video transmission. Using this technology, the video is transmitted into two
separate signals. One is used for color, and the other for brightness. Sometimes S-Video signals
are considered as a type of component video signal. However, its quality is inferior to other
complex component video schemes such as RGB. This technology produces sharper images than
those produced by composite video, which carries the entire set of signals in a single line. For
using SVideo, the device sending the signal must support S-Video output and the device receiving
the signal needs to have an S-Video input jack.
Answer option A is incorrect. DVI stands for Digital Visual Interface. It is a standard for high speed,
high resolution digital display invented by
Digital Display Working Group (DDWG). DVI accommodates analog and digital interfaces with a
single connector. New video cards have DVI as well as VGA ports built into them. Most of LCD
monitors come with a 15-pin VGA connection cable, even if they are capable of handling digital
signals coming from DVI connections. However, some monitors come with both types of cables.
DVI has three main categories of connectors. They are. DVI-A, DVI-D, and DVI-I. DVI-A is an
analog-only connector, DVI-D is a digital-only connector, and DVI-I is an analog/digital connector.
DVI-D and DVI-I connectors are of two types. single link and dual link. DVI supports UXGA and
HDTV with a single set of links.
Higher resolutions such as 1920 x 1080, 2048 x 1536, or more can be supported with dual links.

Mozilla touts Firefox impact in SOPA blackout

Mozilla yesterday extolled the impact of its 12-hour participation in Wednesday's anti-SOPA strike, saying Firefox users and fans generated over a third-of-a-million emails to the U.S. Congress.

Best comptia A+ Training, Comptia A+ Certification at Certkingdom.com

Two days ago, Mozilla blackened Firefox's default home page and redirected its websites to an "action page" asking users to contact their federal representatives and voice their opposition to "Internet blacklist legislation."

Mozilla joined other websites, including Craigslist, Google and Wikipedia, in a one-day "virtual strike" to drum up resistance to the Stop Online Piracy Act (SOPA) and the Protect IP Act (PIPA), bills being considered by the U.S. House of Representatives and the Senate, respectively.

Since Wednesday's blackout, Washington politicians have backpedaled on the legislation. Today, Senate Majority Leader Harry Reid (D-Nev.) postponed next week's vote on PIPA, while Rep. Lamar Smith (R-Texas), chairman of the House Judiciary Committee, said the committee was also postponing action "until there is wider agreement on a solution."

According to Mozilla, Firefox users were instrumental in getting the message to Congress.

"Ultimately, 360,000 emails were sent by Mozillians to members of Congress, contributing a third of all the emails generated by EFF's campaign site," said Mozilla in a blog post Thursday.

Both the revised Firefox home page and the special action page offered users a button that led them to a page hosted by the Electronic Frontier Foundation (EFF), a San Francisco-based Internet rights advocacy group. The EFF page provided a way for visitors to quickly email their House and Senate representatives.

More than half of the people who reached the EFF page from Firefox or Mozilla's websites fired off emails to Congress.

In a separate statement today, the EFF said it had helped users send about 1 million emails.

Mozilla also said approximately 30 million people in the U.S. saw the darkened Firefox home page in their browser, and that 1.8 million visited the open-source organization's own SOPA information and action page.

Mozilla's contribution to the anti-SOPA drive was small potatoes compared to Google's: The search giant, which reportedly signed a deal with Mozilla that guarantees the latter $300 millionannually for sticking with Google on the Firefox home page, collected over 7 million signatures Wednesday on its own online petition.

Avaya SMB collaboration platform gets robust new mobile client

Android and Apple iPhone devices will get a richer conferencing and unified communications experience with Avaya IP Office 8.0.

Microsoft Avaya Exam Training , Avaya Certification and over 2000+
Exams with Life Time Access Membership at http://www.actualkey.com

The latest version of Avaya’s unified communications platform for small and midsize businesses boasts two major changes: a robust mobile application and the ability to integrate communications features into certain key business applications.

The mobile component of Avaya IP Office 8.0 is called one-X Mobile Preferred for IP Office. Initially available for Android devices (Apple iPhone is coming soon), the application allows users to manage who is on a conference call — allowing them to invite, view, mute or drop participants. The mobile application is recognized by the IP Office presence application, so that people can tell when you are available or shouldn’t be disturbed. There also is a “geopresence” feature that broadcasts where someone is located. (Part of me can see the usefulness of this feature, but it also smacks a little bit of employee babysitting.)

one-X Mobile Preferred is an extension of Avaya’s Essential Mobility technology.

The other major enhancement to Avaya’s latest SMB unified communications platform update comes in the form of new plug-ins to widely used business productivity applications. For example, small businesses can use the Avaya platform to make or receive a call from within a Salesforce.com page; they can also go to a single location to view Google Talk and IP Office contact lists.
