Step By Step - Siri Ported To iPhone 4/3GS, iPad [iOS 5 & iOS 5.0.1]

Posted by Ahsan Tasneem | 10:26 AM | , , , , | 0 comments »

Siri has been ported to older iOS devices, including iPhone 4 and 3GS by well known hacker chpwn and stroughtonsmith.
Since Siri was launched along with iPhone 4S as an exclusive feature to Apple’s very latest smartphone, it has scarcely been away from the headlines. Developers have been plugging away to see what the software can really do when unleashed, and if the progress thus far is anything to go by, Siri will be singing songs whilst flipping eggs for your breakfast in no time!
Jokes aside, though, the latest inroads only further increase the suspicion that the fruit company kept Siri as an iPhone 4S-only feature in order to increase sales. It was said that Apple’s first dual-core smartphone was the only device capable of handling the new, exciting technology; but the work of chpwn and friends has certainly made that claim appear as a simple, sensible marketing ploy.
Here is a step by step guide to port Siri on iPhone 4, iPhone 3GS or iPad on iOS 5 or iOS 5.0.1:

Apple's Siri May Pose Threat To Google Search

Posted by Ahsan Tasneem | 11:06 PM | , , , | 0 comments »

Is Siri poaching Internet searchers from Google? That's what The Arora Report's Nigam Arora suggested Monday, citing a "small study" he conducted to "validate the hypothesis that users of Apple's Siri are reducing Google searches."
When Arora says "small," he means it. The unscientific survey of 40 Siri users is anything but conclusive, but there's certainly a lot to chew on—not the least of which is the notion that with Siri on the new iPhone 4S, Apple may just have inserted itself into the search game with an end-around that few people saw coming.
Twenty-seven of the Siri users Arora polled said they hadn't done a single Google search since buying their iPhone 4S. The remaining 13 had conducted two Google searches on average since welcoming Siri into their lives. And "[a]ll 40 users of Siri report that they see no need to go to Google if Siri can answer their question."
Arora's informal study offers some perspective for Google chairman Eric Schmidt's recent claim before Congress that his company is not "overwhelmingly dominant" in search. Schmidt contended that Google faces a number of serious search competitors and even singled out Siri as a "significant development" in the search arena.

The new Apple iPhone 4S can do more than just check e-mail and make phone calls. It's also turning into a new — sometimes sassy, often entertaining — digital friend for millions of consumers.
The most touted new feature, the Siri personal digital assistant, has, hidden in the software, dozens of humorous responses to silly questions.
Consumers are asking Siri for dates, marriage, advice, math equations and even crazy stuff like where to hide a dead body.
To their surprise: Siri usually has an answer.

iPhone 4S - Battery Drain Problem & Solution

Posted by Ahsan Tasneem | 10:48 AM | , | 1 comments »

Apple said Friday that it was still trying to resolve battery drainage issues in the iPhone 4S, despite a patch released earlier this week that was supposed to fix the problem, according to AllThingsD.
"The recent iOS software update addressed many of the battery issues that some customers experienced on their iOS 5 devices," Apple said in a statement to the tech journal. "We continue to investigate a few remaining issues."
As PCMag reported earlier on Friday, many iPhone 4S users have been complained that the iOS 5.0.1 update released Thursday didn't actually resolve the smartphone's battery problems. One user said the update did not make a lick of difference, another said it actually drained his battery even more. PCWorld reported more issues apparently resulting from the patch, like microphone failures, Wi-Fi signal loss, and cellular reception issues.
Days after Apple released the iPhone 4S and iOS 5 last month, users began complaining of plummeting battery life. One user told the Guardian that he experienced a 10 percent drop every hour, and Apple engineers reportedly started contacting iPhone 4S owners about the "known issue" with its battery.
Apple confirmed the bug last week.
"A small number of customers have reported lower than expected battery life on iOS 5 devices," the company said in a statement. "We have found a few bugs that are affecting battery life and we will release a software update to address those in a few weeks."

Note:  The steps posted below was found on a forum and a number of people had already tried & acknowledged that their battery drain issue is resolved by following it

XenDesktop 5.5 VS VMware View 5

Posted by Ahsan Tasneem | 2:10 AM | , , , , | 11 comments »

Below you will find a compilation of features and pricing points for both XenDesktop 5.5 and VMware View 5.0. The prices below are the suggested retail prices, without any discounts.
I noticed that Citrix like to expose every component of their solution as a feature that can be added as part of different editions of the product. VMware on the other hand don’t market all the features as if they were individual components for each edition. None of the vendors is right or wrong, but I would like to align these features.
Despite terminology, technology and marketing differences both products have comparable features. The exceptions are Citrix EdgeSight for Virtual Desktops and Password Manager included in the XenDesktop Platinum version, and VMware vShield Endpoint included in VMware View Premier.

  • ·         Desktop Delivery Controller and Provisioning Services are similar to View Manager and View Composer. Technologies are different but end-result is similar.
  • ·         Citrix HDX 3D for Professional Graphics extends desktop virtualization to advanced users of CAD/CAM and engineering applications. This is not required in VMware View as PCoIP already include the enhancements.
  • ·         Citrix Access Gateway provides secure remote access. VMware View Security Serverprovide similar solution.
  • ·         Repeater accelerate, control and optimize service traffic delivery to branch and mobile users. VMware View PCoIP protocol acceleration is done via a Riberbed appliance. For most use cases acceleration is not required, only WAN links with very low bandwidth.
  • ·         XenDesktop and VMware ThinApp are technically different but both provide similar end-result  in the VDI context. VMware’s Appblast technology should close the gap allowing HTML5 application remoting.
  • ·         Citrix Profile Management and VMware Persona Management also have similar end-result.
  • ·         VMware View 5.0 Media Services provide similar functionality to XenDesktop EasyCall.
  • ·         XenDesktop StorageLink is comparable to the VMware vCenter suite included with VMware View.
  • ·         VMware View Local mode is different than XenClient but both try to achieve similar end-result.
  • ·         VMware View ships with vSphere and XenDesktop ships with XenServer.
  • ·         Citrix EdgeSight Continuous and comprehensive visibility into application performance at the desktop.
  • ·         VMware vShield Endpoint  strengthens security improving performance for endpoint protection by orders of magnitude. vShield Endpoint offloads antivirus and anti-malware agent processing to a dedicated secure virtual appliance delivered by VMware partners. vShield also include RSA DLP (Data Loss Prevention) that helps to classify and block data with 80+ policies for data classification.

How To: Adding Netscreen to NSRP Cluster & Interface Monitoring

Posted by Ahsan Tasneem | 2:45 AM | , , | 2 comments »


NSRP is the protocol that redundant NetScreen devices use to talk to each other when running in various HA configurations. It is the language that allows them to exchange state information and make decisions. Before we detail the specifics of what type of information is exchanged over NSRP, we need to cover a bit more theory.

One of the main goals of HA is to have multiple redundant systems, where a second system can take over in case the first one fails. This is commonly achieved by duplicating the hardware. As with the NetScreen firewalls, any HA setup that is using NSRP implies that there are at least two firewalls of the same model working together. This group of firewalls is called an NSRP cluster, or simply, a cluster (see Figure below).

Note:  The sample configuration shown below is of SSG 520, for any issues related to this post please let me know @ahsantasneem
