What’s coming in Delphi RAD Studio XE2: more details of 64-bit and Mac announced, introducing FireMonkey

10 Comments

Embarcadero’s David Intersimone has posted more details of what is coming in the new version of Delphi and RAD Studio XE2, to tie in with an international publicity tour.

One intriguing comment is a reference to FireMonkey:

with FireMonkey, the GPU-powered next-generation application platform, you’ll be able to create visually stunning HD and 3D business applications

Here is the teaser list of features:

  • Create GPU-powered FireMonkey applications
  • Build 64-bit Delphi applications
  • Create a single application and target both Windows and OS X
  • Extend your multi-tier DataSnap applications with new mobile and cloud connectivity in RAD Cloud
  • Connect any visual element to any type of data using LiveBindings™
  • Modernize the look and feel of your Windows applications with VCL styles
  • Create mobile-optimized web applications and standalone apps for iOS and Android devices using RadPHP

Hmm, so RAD Studio XE2 is targeting iOS and Android not with Delphi, but with RadPHP. That suggests some sort of HTML and JavaScript approach rather than a true native executable.

I was not greatly impressed with Delphi for PHP when I first looked at it. That was four years ago though, and since then Embarcadero has acquired Qadram, the third-party developer behind Delphi for PHP, so I would expect something more worthwhile in the forthcoming new version.

Update: Embarcadero’s Andreano Lanusse has posted more details about FireMonkey.

Android only 23% open says report; Linux, Eclipse win praise

Vision Mobile has published a report on what it calls the Open Governance Index. The theory is that if you want to measure the extent to which an open source project is really open, you should look at its governance, rather than focusing on the license under which code is released:

The governance model used by an open source project encapsulates all the hard questions about a project. Who decides on the project roadmap? How transparent are the decision-making processes? Can anyone follow the discussions and meetings taking place in the community? Can anyone create derivatives based on the project? What compliance requirements are there for creating derivative handsets or applications, and how are these requirements enforced? Governance determines who has influence and control over the project or platform – beyond what is legally required in the open source license.

The 45-page report is free to download, and part-funded by the European Union Seventh Framework Program. It is a good read, covering 8 open source projects, including the now-abandoned Symbian Foundation. Here is the result:

Open Governance Index (%open)
Eclipse 84%
Linux 71%
WebKit 68%
Mozilla 65%
MeeGo 61%
Symbian 58%
Qt 58%
Android 23%

The percentages are derived by analysing four aspects of each project.

  • Access covers availability of source code and transparency of decisions.
  • Development refers to the transparency of contributions and acceptance processes.
  • Derivatives covers constraints on use of the project, such as trademarks and distribution channels.
  • Community structure looks at project membership and its hierarchy.

What is wrong with Android? I am not sure how the researchers get to 23%, but it scores badly in all four categories. The report observes that the code to the latest “Honeycomb” version of Android has not been published. It also has this to say about the Open Handset Alliance:

When launched, the Open Handset Alliance served the purpose of a public industry endorsement for
Android. Today, however, the OHA serves little purpose besides a stamp of approval for OHA
members; there is no formal legal entity, no communication processes for members nor frequent
member meetings.

By contrast, Eclipse and Linux are shining lights. MeeGo and Mozilla are also praised, thought the report does mention Mozilla’s “Benevolent dictators”:

In the case of conflicts and disputes, these are judged by one of two Mozilla “benevolent dictators” – Brendan Eich for technical disputes and Mitchell Baker for non-technical disputes.

Qt comes out OK but has a lower score because of Nokia’s control over decision making, though it sounds like this was written before Nokia’s Windows Mobile revolution.

WebKit scores well though the report notes that most developers work for Apple or Google and that there is:

Little transparency regarding how decisions are made, and no public information provided on this

Bearing that in mind, it seems odd to me that WebKit comes above Mozilla, but I doubt the percentages should be taken too seriously.

It is good to see a report that looks carefully at what it really means to be open, and the focus on governance makes sense.

Same price: four eMachine ER1401 or one Apple Mac Mini

2 Comments

This machine at ebuyer.com caught my eye:

For your £130 you get AMD Athlon Dual Core K325, 2GB RAM, 250 GB hard drive, NVIDIA GeForce 9200, HDMI out, and Linpus 9.5 Linux. The ER1401 also include wifi, 2 USB ports, S/P DIF digital out, headphone out, wired ethernet, and VGA for a standard computer display.

I probably would not have noticed it, except that I have just purchased a Mac Mini:

The Mac has plenty to offer over the ER1401 of course. There is not only the slick new OS X Lion OS, but also a Thunderbolt port, Bluetooth, 4 USB ports, twice as much hard drive space, memory upgradeable to 8GB rather than 4GB, FireWire 800 port, and an SDXC card slot.

Linux is free, but if you decided to put Windows 7 on your ER1401 the cost would climb a bit.

Still, it happens that the Mac mini, Apple’s cheapest Mac, is just over four times the price of the ER1401. If you just need a small computer to do some task like playing BBC iPlayer on your TV, or running Squeezebox server, the eMachine model wins the value prize.

Adobe Edge previewed: another step towards HTML 5

Adobe has released a preview of Edge, a new tool for creating animations in HTML 5, JavaScript and CSS3.

Edge is interesting on two levels. First, HTML 5 lacks strong design tools so a new tool from Adobe is welcome. Edge is a timeline-based tool for creating animations. You import elements such as images, or create text and graphic elements in the tool. Using the timeline, you create keyframes and specify effects. Here is the designer:

and you can view the output right here. This is one of Adobe’s samples, created by Sarah Hunt.

Under the covers Edge uses the JQuery JavaScript library. Here are the includes for this example:

and here are the transition effects on offer:

Edge is not complete yet.  A future update will add a JavaScript editor, making this more interesting for application developers. There will be a documented Edge library that will let you customise and I presume interact with the Edge output. One of the possibilities that interests me is data visualisation. Will Edge support this? Adobe is not yet saying, but it would be a natural move.

Adobe already has an HTML design tool, Dreamweaver. Why another one? Or put another way, why is Edge not a new designer for Dreamweaver rather than a new product in its own right?

This is an early preview, and all things are possible. However, Adobe has a tricky positioning task, given that Edge is encroaching on territory that used to belong to Flash, timeline-based animation. In its FAQ [PDF], Adobe distinguishes its products like this:

Product Sample use cases
Adobe Edge Preview 1 Advertising, simple animations and motion design for new compositions or using existing CSS-based page layouts
Adobe Dreamweaver Websites and web applications for desktops, smartphones, and other devices
Adobe Flash Professional Immersive interactive experiences, mobile applications, gaming, premium video, advertising
Adobe Flash Builder Rich Internet Applications (RIAs) and mobile applications

This table fails to mention what must be part of the core rationale for Edge, which is working on Apple iOS, the mobile operating system for iPhone and iPad that does not run Flash content. If you view the demo page above on the iPhone 4 or iPad 2, you will find that it works fine.

Adobe’s distinctions in the table above are not particularly clear. Leaving aside the relative merits of Flash and HTML 5 as technologies, a key question for developers and designers is one of reach. HTML 5 has a reach that extends to iOS and to other devices that do not run Flash in the browser. Flash has a reach that replaces browser-dependency with dependency on Adobe’s runtime, which can be a good thing.

Incidentally, I asked Adobe during a press briefing about mobile support and also browser requirements for Edge content, but there is no official statement on this yet.

Is Adobe moving away from Flash towards standards-based HTML tools? The purpose of a table like the one above is to insist that this is not the case and that Adobe will continue to support both. Nevertheless, Edge is a significant move. A gradual decline in Flash usage in favour of HTML 5 is not necessarily bad for Adobe. Designers will use the same Adobe tools to create content for Edge as they do for Flash.

What about Wallaby, another Adobe experimental project which exports Flash content to HTML, in effect making Flash Professional an HTML 5 authoring tool? Adobe says that Wallaby and Edge are separate projects and there is no plan to have Edge import Wallaby content. Still, you would have thought that, if Wallaby makes it into an official product, some compatibility is inevitable.
