Netscape’s Constellation

Rank: 1-3

Netscape devotees all over the place await the looks of the paranormal Constellation with all of the fervor of Hale-Bopp comet followers, with its fable of an enormous UFO mothership hidden in its tail, arriving from the Galactic Federation to rescue true believers from the apocalypse.

Constellation, so the opposite fable goes, is Netscape’s secret weapon within the cosmic battle for the hearts
and minds of the intranet/Web person.

It is Netscape Constellation/Communicator vs. Microsoft Web Explorer 4.0 Lively Desktop/Home windows 97: which one will The Drive be with?

I needed to know. So I went on a pilgrimage to Mountain View for an viewers with Constellation’s guru/inventor, Mike McCue. McCue was CEO of Paper Software program, which developed Netscape’s Live3D and was acquired final yr by Netscape.

Constellation “NUI” integrates
push media and desktop

“Microsoft is placing the Web into the desktop; we’re placing the desktop into the Web,” McCue stated fervently, firing up his laptop computer. “Microsoft Lively Desktop is tied to the Home windows tree construction, so content material suppliers’ interfaces all look the identical and the platform is
restricted to Home windows 97.”

McCue calls Constellation a NUI — Community Person Interface — which is able to substitute GUIs (graphical person interfaces), he believes. The thought: put the person in direct contact with Web content material and a personalised person interface as an alternative of entry by means of menus, instruments bars, home windows, timber of information and folders, and different operating-system instruments.

He first demo’d (not an actual demo, only a presentation) how Constellation will permit a developer to take away “chrome” (menus and toolbars, and many others.) and take over your entire display. “Constellation is the following evolutionary step up from conventional Internet pages. Now you can create content material that runs full-screen, completely immersive!”

I felt like I used to be speaking to Steve Jobs within the early Apple days.

As an alternative of a scroll bar, McCue continued, with Constellation, you may transfer across the display by grabbing objects with the mouse and flinging them. Need to return the working system? Simply bump the highest of the display (the trick: a brand new window.moveto JavaScript object within the newest JavaScript API).

However he confirmed me why you could not need to: Selector, a pop-up exhibiting your energetic data: cellphone ebook, tasks, paperwork you are engaged on, spreadsheets, and many others. The design idea: a single person interface that transparently retrieves paperwork in your pc in addition to the Internet.

McCue subsequent confirmed me layering: a number of layers of pictures and textual content that pop up when a mouse passes over them, because of Netscape’s new LAYER tag. Layers might be clear and animated. “Think about a 3D VRML mannequin that floats over a web page and acts as an imagemap,” McCue steered.

Constellation’s method is clearly object- and content-oriented as an alternative of file- and application-oriented, one thing Jobs would perceive instantly.

Netcasting: built-in push media

However past the snazzy new person interface, McCue layed out Netscape’s grand plan for delivering content material to the desktop, which he calls”Netcasting.” Constellation, he stated, will assist 4 netcasting schemes:

  • E-mail for sending pages, utilizing Inbox Direct expertise for information headlines, and many others.
  • Offline searching (much like Freeloader: ballot a web page and obtain content material at intervals).
  • Notification (much like BackWeb and Intermind Communicator).
  • Channels, based mostly on Marimba broadcast expertise, for automated background supply and updating of content material and apppications.

Netcast content material will likely be delivered by way of personalised InfoBlocks — much like BackWeb however interactive and usually on the backside of the display. These will allow you to entry instruments (reminiscent of search engine types), notification messages, favourite websites, information tickers, channels and different content material. The InfoStream will replace InfoBlocks within the background or throughout off hours.

You will create your personal customized InfoStream profile. And your server will mechanically obtain custom-made info to your desktop by way of e mail, Internet web page polling, or by way of a channel from a Marimba transmitter.

That certain beats the half dozen push media and notification apps hovering on my desktop battling each other for dominance. Plus you are not constrained to simply these websites {that a} specific push media service provides, and you do not have to undergo their particular weirdo person interface and a centralized service. You determine which websites you need to subscribe to and go there instantly.

I requested McCue if netcasting replaces all these complicated push media choices. “Not utterly,” he stated. “There are some issues they do this we do not. We took the components that have been simple to make use of and didn’t require main infrastructure modifications and mixed them into one easy person interface that eliminates the center man.”

This butts up in opposition to Microsoft’s push-media scheme head-on, in fact, with PointCast expertise constructed into Web Explorer 4.0.

Netscape has yet another intelligent strategic device: HomePort. This can be a private workspace on the server of your alternative that allows you to retailer your energetic paperwork and particular apps. The thought: you’ll be able to entry
your HomePort from no matter pc you might be on by clicking on the HomePort icon. Your presently energetic paperwork and person interface are then mechanically replicated to no matter machine you occur to be on (in a safe cache).

McCue supplied an instance: you may have a gross sales channel that allows you to entry your private spreadsheets and shows plus the corporate’s newest product data, all mechanically downloaded to your laptop computer.

“We’re additionally working with Navio, a Netscape spinoff that’s doing consumer-oriented implementations of Netscape,” he added. “Finally, for instance, you’ll go an airport kiosk and entry your HomePort — and even entry it at an ATM.”

Reside websites substitute Web pages

The Subsequent Massive Factor: a brand new breed of “stay websites” — Web pages designed for the Constellation NUI that combine push media — predicted McCue.

Let’s nail this down with an instance. To illustrate you subscribe to the hypothetical MTV stay website. You specify the music you want and it is mechanically downloaded within the background or in a single day.  Clips for brand spanking new music in your style might be mechanically broadcast to you — no have to click on and wait.

Subsequent, you click on in your Airways InfoBlock and register for notification of flight and worth modifications. When new flights come alongside, the Airways server sends an e mail message to the InfoStream, which opens up the schedule in your desktop (if that is what you have requested it to do). Or your may need a Financial institution channel that sends a notification to Constellation {that a} examine has simply cleared. Your private finance app then makes use of that to mechanically replace your checkbook.

Must examine on a package deal cargo? Click on the Fedex InfoBlock and it zooms out to full display within the Fedex stay website, the place you punch in an airbill quantity and get an on the spot package deal standing. One click on and also you’re again by yourself desktop. Click on on the Selector and your display turns into your present Phrase doc.

What about intranets? “From an IS supervisor perspective, in a big firm you need to assist many platforms and working techniques,” McCue stated. “We’re creating one atmosphere that appears and feels the identical whatever the working sytem. It is not tied to a selected system or onerous drive. And since stay websites serve pure HTML, it will get by means of firewalls.” In contrast to some push-media schemes.

OK, I used to be offered. Now how do I create my very own stay website? I requested Tim Hickman, Constellation Product Supervisor, for some suggestions.

“Reside websites might be simply created with simply HTML and JavaScript,” Hickman stated. “And they are often animated utilizing JavaScript, applets, and plug-ins. We’re additionally altering the cache mannequin to permit applets to work offline to keep away from time-consuming downloading.”

What about servers? “The intelligence is within the shopper,” he stated. “So stay websites work with any regular HTTP server. We’re not requiring content material suppliers to purchase a brand new server or put in a complete new infrastructure. For notifications, the one factor that goes on the server is an easy preferences
file for every person with a URL pointer, the chosen polling mechanism, and the way usually the location is to be polled.” 

Netscape can be offering a shopper pull answer based mostly on Marimba Castanet expertise. “You should utilize a mix of HTML, JavaScript, and Java, relying on the complexity wanted. Every subscriber can have his or her personal customized channel on that website and might arrange an individualized channel in just some minutes,” Hickman stated.

He stated Netscape can be growing APIs for JavaScript, Java, and C++ to permit apps to speak with Constellation. A Channel Builders Information is due out this spring, to be posted on the Netscape Web site.

Consider: Constellation itself isn’t but an introduced product; it is nonetheless a expertise idea. The product, no matter it is known as, is due out mid-year.

One massive concern with stay websites: whereas the content material will likely be based mostly on open JavaScript and HTML requirements, you may want Constellation to entry the complete performance (polling, background downloading, off-line searching, and so forth).

Will Web Explorer 4.0 assist all that? Do not maintain your breath.

In any occasion, Internet surfers utilizing Constellation (or Lively Desktop) will discover two kinds of websites: boring static ones and stay/energetic websites with customized supply of knowledge and wealthy experiences. Static websites
are historical past.

Will the Microsoft empire strike again with Home windows 97 and Lively Desktop? Keep tuned, girls and boys, for the following thrilling episode….
