Other Enhancements Under Consideration Some of the other things under consideration by the Expert Group include the following: Access to the unfetched state of detached entities. Solaris has a different kernel and a different implementation of the system libraries, but it implements most of the same interfaces as Linux. The Fine Print Most of these features are still very much in development, and they are thus apt to change scope or be removed from the release if the team's goals for them are not reachable. For example, most developers work within a single domain and machine, and they would choose the developer profile to improve performance and expend the least administrative effort. Another limitation is that Java Persistence Query Language queries are always polymorphic. Installer Improvements The installation process for a new JRE should be simpler and more user-friendly. This is not to shrug off a difficult problem but to indicate that the Java platform is facing some basic physical constraints at the OS and hardware level that the team must work within. Could they be better? The platform cannot magically preload the pages just prior to launching. A standard message format ensures that all components understand one another. The reason that warm start is so much faster is that once some data has been read off the disk, the OS places it in the disk cache. us, Yahoo UI Widgets, Spry, DHTML Goodies, and Google. Java Persistence has had a great start, with strong acceptance by the Java community. Swing applications both simple and complex should benefit from much better runtime performance on Windows as a result. In the GlassFish server, WSIT is used to provide advanced web services features such as bootstrapping, optimizing communication, reliable messaging, atomic transactions, security, and trust. This feature should finally be enabled by default, exposing Swing to extremely fast hardware acceleration through the graphics processor. Solaris has a different kernel and a different implementation of the system libraries, but it implements most of the same interfaces as Linux. The main goal of Project GlassFish has been to produce an application server that implements the Java EE standard. Graphics performance on Microsoft Windows. It's pushing Rails further than it's ever gone before, he explained. Within the cluster, the replication framework makes sure that the responding member is provided the state information that it needs to provide service. Dynamic attributes and property changes are allowed without requiring a server restart.-- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Re: [SLUG] USB to serial
i bought one from dick smiths (whilst in new zealand), just happened to be on special so i thought it might come in handy. it really has! the linux kernel has a stable driver that picks it up automagically in debian. windows XP doesnt know what it is until you install a driver then it works fine. if you look in the linux-usb (or is it usb-linux) website, there is considerable discussion on usb to serial. they will come up as /dev/ttyUSB(X) devices. from what i have read and from my own experiences with it, use software flow control (or none) not hardware. hardware flow control tends to end badly. but yeah, for anyone who is poking with switches and routers a lot a usb serial device is really handy. especially given its (mine at least) very long cable - making up for the lack of length with many supplied serial leads. you can also extend it with one of those usb cables you get with every usb stick.
