Apple Mafia wants 30% Cut of App Subscriptions

February 16, 2011

Apple plans to take a 30% cut of all subscriptions on the iPhone & iPad. According to Techcrunch, Steve Jobs explained:
“Our philosophy is simple—when Apple brings a new subscriber to the app, Apple earns a 30 percent share; when the publisher brings an existing or new subscriber to the app, the publisher keeps 100 percent and Apple earns nothing. All we require is that, if a publisher is making a subscription offer outside of the app, the same (or better) offer be made inside the app, so that customers can easily subscribe with one-click right in the app. We believe that this innovative subscription service will provide publishers with a brand new opportunity to expand digital access to their content onto the iPad, iPod touch and iPhone, delighting both new and existing subscribers.”
This is a game changer! Will taking a 30% cut of 3rd party subscriptions cause a mass exodus of developers to Google Android?

SPIRIT DSP Lands Another Win - Huawei

February 16, 2011

SPIRIT DSP announced today the second big news of the week. Yesterday, they announced Viber, a VoIP app for the iPhone was powered by SPIRIT DSP and now today they are announcing that Huawei Technologies has extended its license with SPIRIT DSP for HD voice and video to carriers. Interesting that I never hear from SPIRIT DSP's competitor Global IP Sound (GIPS) any more -- who at one time powered Skype.

Anyway, under terms of the agreement, Huawei, an existing SPIRIT customer since 2007, will use SPIRIT's TeamSpirit Voice&Video Engine PC in its IMS (IP Multimedia Subsystem), Unified Communications (UC) and Fixed Mobile Convergence (FMC) solutions to carriers from the Huawei core network, delivering a PC video softphone to Huawei's carrier customers.

Why Spirit DSP Powers Viber's Popular HD Mobile VoIP App

February 15, 2011

SPIRIT DSP, a voice and video over IP Engines provider, today announced that its TeamSpirit Voice Engine Mobile is powering the new Viber application that offers free HD Voice over IP (VoIP) calls from the iPhone.  

"Within three days of launching Viber on the iPhone late last year, we received one million downloads, and seven million within the first month, quickly becoming the No. 1 free app in the Netherlands, Spain, Singapore, Taiwan, Israel and several other countries, validating the enormous demand for quality, free mobile VoIP calling," said Viber Media's CEO Talmon Marco.  "We're incredibly pleased with this massive uptake and can credit SPIRIT's Voice Engine Mobile for the quality of the Viber voice experience."

Asterisk + OpenBTS = Be Your Own Wireless Carrier

February 14, 2011

OpenBTS (Open Base Transceiver Station) is a free softare implementation of the GSP protocol allowing the creation of software-based GSM access points that enable standard GSM mobile phones to make phone calls without using traditional wireless providers' networks. In other words, create your own homebrew cellular network!

According to the OpenBTS Project, OpenBTS is an open-source Unix application that uses the Universal Software Radio Peripheral (USRP) to present a GSM air interface ("Um") to standard GSM handset and uses Asterisk software to connect calls leveraging SIP and VoIP.

The goal of the project is to reduce the cost of GSM service provision in rural areas and the developing world. They explain, "In plain language, we are working on a new kind of cellular network that can be installed and operated at about 1/10 the cost of current technologies, but that will still be compatible with most of the handsets that are already in the market. This technology can also be used in private network applications (wireless PBX, rapid deployment, etc.) at much lower cost and complexity than conventional cellular."

During the past few Burning Man festivals, OpenBTS has performed a week-long live field test under special temporary WE9XJN authorization to use certain wireless frequencies.

Cisco Responds to Polycom's Adoption of TIP and Interoperability

February 10, 2011

A Cisco representative saw my article about Polycom's announcement to support Telepresence Interoperability Protocol (TIP) and she thought I'd be interested in hearing Cisco's take. David Hsieh, vice president, emerging technologies, Cisco responded to this news announcement as follows:

"We are pleased to hear that Polycom is joining other companies in adopting the Telepresence Interoperability Protocol (TIP), the only open, multi-screen Telepresence interoperability protocol available today. TIP, originally developed by Cisco to enable multi-screen telepresence interoperability, was turned over to the IMTC (International Multimedia Teleconferencing Consortium) to be managed as an industry standard.  It is not a Cisco proprietary protocol — it’s an open protocol available to anyone in the industry. Wins SMS Voting Contest at StartupCamp3 at ITEXPO

February 9, 2011

I was at ITEXPO East in Miami and got to see some cool companies demoing their products on stage in front of hundreds of people. At the end we got to vote using our cell phones and SMS. Competition was tight, but in the end pulled out the win with their tutoring/study application that directly integrates with Facebook. You can invite friends to work on calculus problems for instance - including calculus symbols like the differential and integral signs.

Polycom UC Intelligent Core Platform Supports TIP Standard - Interoperable with Cisco

February 9, 2011

June of last year I wrote about how Cisco had to adopt the open source TIP protocol before the EU would approve Cisco's acquisition of Tandberg:
An interesting back story behind the Cisco acquisition of Tandberg is that Cisco had to make sure Cisco's open source and free TIP (Telepresence Interoperability Protocol) protocol was used. The EU wouldn't approve the acquisition of Tandberg without Cisco agreeing to use this protocol. There have been obvious concerns (including my own) that Cisco/Tandberg could create a proprietary telepresence platform that locked out third-party competitors. Cisco and Tandberg just made an announcement stating advanced multiscreen telepresence interoperability with each other as well as other third-party systems, by integrating the Telepresence Interoperability Protocol (TIP) on Cisco's newly acquired Tandberg TelePresence Server.
The fruits of that effort are now realized with today's announcement from Polycom.

Flash 10.2 Adds Full Screen on Separate Monitors

February 9, 2011

Flash 10.2 finally adds the ability to watch full screen video on a separate monitor while you continue to work on your primary monitor. Guess this makes the popular Flash full screen hack called FlashHacker obsolete. Now everyone can happily watch Hulu, YouTube, Liveleak, and all other Flash video in full screen on a second monitor while simultaneously checking email and surfing the web.  In theory, any Flash-based video conferencing product (i.e.

Snow Blower Revenge: Man Buries Car of Woman who Stole his Shovel

February 7, 2011

A Chicago man who works for a security company was none to pleased to discover his snow shovel was stolen. But as Warner Wolf would say "Let's go to the videotape!". David Welles checked out his security footage from the many surveillance cameras around his house, according to the Chicago Tribune and discovered a woman swiping his shovel from his front steps.

A 2nd camera saw the woman go around the corner and then use his snow shovel to dig out her car. His 2 year old daughter cried and was upset that her dad couldn't finish making a snow igloo.
