Sun offers potpourri of open-source plans

Updates on OpenSolaris, Java, and GlassFish app server given at summit event

Sun offered informational updates Monday on several ongoing efforts in the open-source arena, including product plans for the OpenSolaris version of the Solaris OS, Java, and the GlassFish application server.

Cited were improvements like a binary release of OpenSolaris and plans for dynamic scripting support in Sun's Java Virtual Machine. Executives from throughout the company met with the media at Sun's headquarters campus for an open-source "summit" briefing.

"We have so many people who work on open source inside Sun," that they must be brought together for an annual conference, said Simon Phipps, chief open-source officer at the company.

Open source, Phipps said, features community developers who share source code licensed in a particular way and use that to create things that enrich them.

Contributions are given back to the community to enrich everyone, like the craft guilds of the Middle Ages, he said. "This has been called communism by some speakers. It's been called a cancer on society by others. I would suggest to you that this is more like capitalism, it is more like a connected capitalism where people synchronize their self interests so that they are collaborating together," said Phipps.

Sun has extensive product plans in open source, As part of Project Indiana, which is an effort to make Solaris more like Linux in areas like packaging, Sun will offer a developer preview of the OpenSolaris version of Solaris featuring a binary distribution this month. The general release version is planned for March 2008.

With the open-sourcing of Solaris two years ago, Solaris began to appear on the radar screen of open-source developers and deployers, said Ian Murdock, chief operating systems platform strategist at Sun and founder of the Debian Linux distribution.

"What we're trying to do is make it easier for people to get into the OpenSolaris community, and we do that by delivering [the OS] in binary form," said Murdock.

A packaging system in OpenSolaris, which will be featured in the preview and is called Image Package System, will take a snapshot of a system prior to an upgrade. Users can roll back to what the system looked like before the upgrade if necessary.

An analyst in attendance welcomed Sun's update on Project Indiana.

"I think there's still some ambiguity on what is the future of Solaris in a Linux world," said Raven Zachary, research director for open source at The 451 group. But there is an opportunity for Sun to engage Linux and take advantage of Linux technology the same way Linux has leveraged Solaris technology like the DTrace tracing framework, Zachary said.

Plans also call for Solaris to be offered in a more modular fashion, so it could be used in different systems ranging from servers and desktops to appliances. A port of Solaris to the PowerPC plan also is being developed.

Sun officials talk OpenJDK, GlassFish, and iPhone

Sun officials also discussed progress of OpenJDK, which is the open-source Java development kit for Java Platform, Standard Edition. About 96 percent of Java code has been cleared for use in the open-sourcing of Java, said Mark Reinhold, Sun chief engineer for Java Platform Standard Edition.

Afoot is a "kitchen sink" language project to explore new language features that could wind up in Java. Another effort project is intended to improve performance of languages other than Java, such as Ruby and Python, to run on the HotSpot Virtual Machine.

OpenJDK is switching to the Mercurial version control system, enabling contributions from the community at large. Meanwhile, an OpenJDK governance board has been formed to oversee OpenJDK.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.
