The Power of Multithreaded

Applications, Handheld-style"> So why are you continuing to develop and support Palm OS 5 [now called Garnet]? Slotnick: We have a big installed base of Palm OS 5 users now, and they love the platform. Theyve taken it in many different directions, everything from wearable devices to factory floor automation to telephones. The licensees have been very creative with what they can do with the foundation of OS 5.
With Palm OS 5, everyone knows how to work with it. There is a little bit of a learning curve to take advantage of the ARM-native development on OS 6. But now you can write an entire application native in OS 6.
OS 6 is designed to make much more sophisticated and diverse devices of the future. OS 5 is preferred for devices for today. We expect the transition to take a few years. Cook: And look at all the award winning products on OS 5! What about application compatibility from OS 5 to OS 6? Slotnick: We provide forward compatibility with OS 5 applications; we continue to support older programs. We developed a thing called PACE, Palm Application Compatibility Environment, when we moved from OS 4 to OS 5. The move from 4 to 5 was from [Motorola] 64K to ARM. Pace was an emulator, and it enabled 64K applications to run on ARM. As part of Sahara, we brought forward PACE, and we continue to support 64K apps [on OS 6, a k a Cobalt]. On top of that we have a multiprocessing, multithreaded operating system with true ARM-based memory protection and hardware assist. We have frameworks for security and multimedia. It has a stream-based, socket API so developers can use standard APIs. Because its multiprocessing and multithreaded you can run multiple network applications simultaneously. [Slotnick then began to describe what he demonstrated in the morning keynote session.] We have a new media player thats part of the product. We had a DAT-based movie running, it was hooked to the device, and a simulator running on a PC, using a standard reference platform with radio hardware and software. I called up the simulator, started the movie, and called a guy in front of the PC. He picked up the phone, while the movie ran in the background. While we were talking, we popped up a stock ticker in front of the application. So we had three things running in parallel. Next Page: New Devices, New Applications

With more than 20 years experience in consulting, technology, computers and media, Jim Louderback has pioneered many significant new innovations.

While building computer systems for Fortune 100 companies in the '80s, Jim developed innovative client-server computing models, implementing some of the first successful LAN-based client-server systems. He also created a highly successful iterative development methodology uniquely suited to this new systems architecture.

As Lab Director at PC Week, Jim developed and refined the product review as an essential news story. He expanded the lab to California, and created significant competitive advantage for the leading IT weekly.

When he became editor-in-chief of Windows Sources in 1995, he inherited a magazine teetering on the brink of failure. In six short months, he turned the publication into a money-maker, by refocusing it entirely on the new Windows 95. Newsstand sales tripled, and his magazine won industry awards for excellence of design and content.

In 1997, Jim launched TechTV's content, creating and nurturing a highly successful mix of help, product information, news and entertainment. He appeared in numerous segments on the network, and hosted the enormously popular Fresh Gear show for three years.

In 1999, he developed the 'Best of CES' awards program in partnership with CEA, the parent company of the CES trade show. This innovative program, where new products were judged directly on the trade show floor, was a resounding success, and continues today.

In 2000, Jim began developing, a daily, live, 8 hour TechTV news program called TechLive. Called 'the CNBC of Technology,' TechLive delivered a daily day-long dose of market news, product information, technology reporting and CEO interviews. After its highly successful launch in April of 2001, Jim managed the entire organization, along with setting editorial direction for the balance of TechTV.

In the summer or 2002, Jim joined Ziff Davis Media to be Editor-In-Chief and Vice President of Media Properties, including, Microsoft Watch, and the websites for PC Magazine, eWeek and ZDM's gaming publications.
