"We are proud to announce the open source release of J2ObjC, a Google-authored translator that converts Java source code into Objective-C source for iPhone/iPad applications. J2ObjC enables Java code to be part of an iOS application's build, as no editing of the generated files is necessary. The goal is to write an application's non-UI code (such as data access, or application logic) in Java, which can then be shared by Android apps, web apps (using GWT), and iOS." Huh.

"VM alonside each other with lots of marshling between VM, because your .NET application needs to make use of the DalvikVM APIs.
Have you actually used it and run into these supposed performance problems? Ive used it, and I haven't. "
How many devices have you tried it on?
Actually you might find this talk interesting,

Just code the core of your application in C or C++, and make use of the platform native UI for the best user experience.
As for WP7, just let it die, as WP8 also supports C++.

Yeah, no. To do that, you'd still need JNI on Android, and a Cocoa bride on iOS since key APIs are not available as native interfaces.
You're doing the same bridging that Mono does, albeit without the slight double GC perf impact. "
In Android's case JNI is an issue, but not as much as with Mono.
See Andreia's talk, there are some exposed APIs that go multiple times between VMs.
In iOS there is no marshalling happening.
Also, nice little pot shot at WP7, but it has over 100,000 apps, and moving forward, C# will still be the majority language (as it is for Windows 8 apps).
In Germany, the only person I've seen carrying a WP7 mobile outside a store, was a guy I've met that works for a startup that develops WP7 games.
Seriously, I don't get the Mono and C# bashing. Sure, maybe if you felt like hurting your productivity enough, you could use C++, but Mono has been proven to work in the real world.
Don't take it wrongly. Personally my only issue is that Mono/C# is promoted as the only way to achieve portability of native application across mobile platforms, when actually other solutions do exist, depending on what platforms are valuable to target.

At an event earlier today, Microsoft unveiled the next Xbox - the third model, but confusingly named Xbox One. The big focus was TV, integrated Kinect, and all the other stuff we all expected to be forced down our throats. I think it took them 25 minutes to actually come to what should be the core of the story: gaming. Nothing groundbreaking in the gaming department, except for how Microsoft intends to handle the used games market and borrowing games from friends: pay up, buddy!

The day has finally come! Jolla has finally announced the launch device for its Sailfish operating system - and by god this is a looker. It's decidedly different from other phones out there, but it has good specifications and carries a relatively reasonably price tag - EUR 399, and it's up for pre-order today, shipping in the fourth quarter of this year.

Why does Google get so much credit in the technology industry? Why, despite the company's many obvious failings, do many geeks and enthusiasts still hold a somewhat positive view on the all-knowing technology giant? A specific talk at Google I/O this week provides the answer.

"Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is one of those news items that's fun to write, fun to read, fun to comment on, and where no one will be able to say anything unkind. It's all just one big ball of awesome fluffiness. TuneTracker, the BeOS radio automation software, has just released something very special: TuneTracker System 5, the first version designed entirely and specifically for Haiku. In fact, it actually includes Haiku in the software package. Better yet, TuneTracker also unveiled several system-in-a-box products - which have Haiku and TuneTracker pre-installed.

Exactly twenty years ago, a document was published that played a huge role in establishing the web as we know it today. Twenty years later, and this simple and straightforward document is proof of an irrefutable fact: while closed technologies can change markets, open technologies can change the world.

Oh multitasking. That staple of computing that got thrown out the window with many modern smartphones. We got some rudimentary thing in its place - but even as multitasking on phone and tablets improves, its user-visible side remains cumbersome. Windows 8 has a neat implementation, and now it's time Android follows in it footsteps.

They're here! Whether that excites you or not remains to be seen, but the Galaxy S4, which will most likely become the best selling Android smartphone of the year by a huge margin, has been reviewed by all the major sites, and there's lots of interesting conclusions in there - although I think most of you will get the gist.

Nokia has posted its quarterly results for the first quarter of 2013, and just like the quarters that came before, there's not a whole lot of good news in there. The rise in Lumia sales still can't even dream of making up for the sales drop in Symbian phones, and when broken down in versions, the sales figures for Windows Phone 8 Lumias in particular are very disappointing. In North America, Nokia is getting slaughtered.More Features »
