The Windows Phone Developer Tools January 2011 Update includes:

• Windows Phone Emulator Update – Exposes copy/paste functionality in the Windows Phone 7 emulator. For more information, see How to: Test Copy and Paste in Windows Phone Emulator. End users can use the copy and paste functionality only after receiving the corresponding update to the Windows Phone 7 operating system.

• Windows Phone Developer Resources Update – Fixes a text selection bug in pivot and panorama controls. In applications that have pivot or panorama controls that contain text boxes, users can unintentionally change panes when trying to copy text. To prevent this problem, open your application, recompile it, and then resubmit it to the Windows Phone Marketplace.

• Windows Phone Capability Detection Tool – Detects the phone capabilities used by your application. When you submit your application to Windows Phone Marketplace , Microsoft performs a code analysis to detect the phone capabilities required by your application and then replaces the list of capabilities in the application manifest with the result of this detection process. This tool performs the same detection process and allows you to test your application using the same list of phone capabilities generated during the certification process. For more information, see How to: Use the Capability Detection Tool.
• Windows Phone Connect Tool – Allows you to connect your phone to a PC when Zune® software is not running and debug applications that use media APIs. For more information, see How to: Use the Connect Tool.
• Updated Bing Maps Silverlight Control – Includes improvements to gesture performance when using Bing™ Maps Silverlight® Control.

WPDT Fix includes:

• Windows Phone Developer Tools Fix allowing deployment of XAP files over 64 MB in size to physical phone devices for testing and debugging.

The BingMap updates were quite welcome too! There are two bits to this update, first grab the Windows Phone 7 January Patch, then install the Visual Studio 2010 tooling update.

Today also marked the release of Internet Explorer 9 Release Candidate which brings a nice bunch of (much needed) updates to IE9 and standards in general with a cool smooth UI.  Ars has a great write up on IE9 RC too which will be far better than what I can write up.

Amongst the changes from the changelog:

This version is a major update. The following major new features were added:

• Following the acquisition of Sun Microsystems by Oracle Corporation, the product is now called Oracle VM VirtualBox and all references were changed without impacting compatibility
• Experimental support for Mac OS X guests (see the manual for more information)
• Memory ballooning to dynamically in- or decrease the amount of RAM used by a VM (64-bit hosts only) (see the manual for more information)
• Page Fusion automatically de-duplicates RAM when running similar VMs thereby increasing capacity. Currently supported for Windows guests on 64-bit hosts (see the manual for more information)
• CPU hot-plugging for Linux (hot-add and hot-remove) and certain Windows guests (hot-add only) (see the manual for more information)
• New Hypervisor features: with both VT-x/AMD-V on 64-bit hosts, using large pages can improve performance (see the manual for more information); also, on VT-x, unrestricted guest execution is now supported (if nested paging is enabled with VT-x, real mode and protected mode without paging code runs faster, which mainly speeds up guest OS booting)
• Support for deleting snapshots while the VM is running
• Support for multi-monitor guest setups in the GUI for Windows guests (see the manual for more information)
• USB tablet/keyboard emulation for improved user experience if no Guest Additions are available (see the manual for more information).
• LsiLogic SAS controller emulation (see the manual for more information)
• RDP video acceleration (see the manual for more information)
• NAT engine configuration via API and VBoxManage
• Use of host I/O cache is now configurable (see the manual for more information)
• Guest Additions: added support for executing guest applications from the host system (replaces the automatic system presimparation feature; see the manual for more information)

Download from VirtualBox or get the Windows build. I’m really hoping the good Oracle keeps VirtualBox open, this is one kickass bit of kit.

So what is WebM?

WebM includes:

• VP8, a high-quality video codec we are releasing today under a BSD-style, royalty-free license
• Vorbis, an already open source and broadly implemented audio codec
• a container format based on a subset of the Matroska media container

Wonder what MSFT and Apple are going to do? In either case, interesting times ahead for video.

Oh hai, I almost forgot, from their FAQ, some interesting points – besides the Licensing bits.

If I have a video card that accelerates video playback, will it accelerate VP8?

The performance of VP8 is very good in software, and we’re working closely with many video card and silicon vendors to add VP8 hardware acceleration to their chips.

Will WebM files play on my TV, set-top box, PVR, etc.?

Stay tuned! The WebM community is working with hardware manufacturers to bring WebM support to a wide range of devices.

When will other Google products support WebM and VP8?

WebM support in Android is expected in the Gingerbread release (currently planned for Q4, 2010). We expect many other Google products to adopt WebM and VP8 as they prioritize it with their other product requirements. Keep an eye on the WebM blog for announcements.

Man, Google rocks!

I’ve also fixed a long standing bug with my particular configuration of WordPress that runs on IIS which causes the “Older posts” link at the bottom does not function for the second page. The WordPress generated URL for this is

Which is a bit problematic, this ofcourse can be reproduced only on IIS from my musings (serves me right eh?). There are a couple of suggestions by people on the forums already, but I wasn’t too keen on them as they seemed too high-level fixes.

I’ve enabled Permalinks with this format:

So I looked through the sources to see why this was happening. After a bit of snooping about I got to the get_pagenum_link function in wp-includes/link-template.php file.

Heres a bit of source for reference – this is with WordPress 2.9.2:

function get_pagenum_link($pagenum = 1) {
	global $wp_rewrite;

	$pagenum = (int) $pagenum;

	$request = remove_query_arg( 'paged' );

	$home_root = parse_url(get_option('home'));
	$home_root = ( isset($home_root['path']) ) ? $home_root['path'] : '';
	$home_root = preg_quote( trailingslashit( $home_root ), '|' );

	$request = preg_replace('|^'. $home_root . '|', '', $request);
	$request = preg_replace('|^/+|', '', $request);

	if ( !$wp_rewrite->using_permalinks() || is_admin() ) {
		$base = trailingslashit( get_bloginfo( 'home' ) );

		if ( $pagenum > 1 ) {
			$result = add_query_arg( 'paged', $pagenum, $base . $request );
		} else {
			$result = $base . $request;
		}
	} else {
		$qs_regex = '|\?.*?$|';
		preg_match( $qs_regex, $request, $qs_match );

		if ( !empty( $qs_match[0] ) ) {
			$query_string = $qs_match[0];
			$request = preg_replace( $qs_regex, '', $request );
		} else {
			$query_string = '';
		}

		$request = preg_replace( '|page/\d+/?$|', '', $request);
		$request = preg_replace( '|^index\.php|', '', $request);
		$request = ltrim($request, '/');

		$base = trailingslashit( get_bloginfo( 'url' ) );

	if ( $wp_rewrite->using_index_permalinks() && ( $pagenum > 1 || '' != $request ) )
		$base .= 'index.php/';

		if ( $pagenum > 1 ) {
			$request = ( ( !empty( $request ) ) ? trailingslashit( $request ) : $request ) . user_trailingslashit( 'page/' . $pagenum, 'paged' );
		}

		$result = $base . $request . $query_string;
	}

	$result = apply_filters('get_pagenum_link', $result);

	return $result;
}

This function (from reading through) essentially generates the links for the page numbers & page navigation taking into account Permalinks if configured. This is all fine and dandy for Unix hosts but for Windows, unfortunately this bit of code fails us.

...
$request = preg_replace( '|page/\d+/?$|', '', $request);
$request = preg_replace( '|^index\.php|', '', $request);
$request = ltrim($request, '/');
...

As the preg_replace is case sensitive, it will not replace the invalid Index.php that is seen on IIS. So the easiest fix is to tweak the regex pattern a little bit and tell it be case insensitive.

...
$request = preg_replace( '|page/\d+/?$|', '', $request);
$request = preg_replace( '/|^index\.php|/i', '', $request);
$request = ltrim($request, '/');
...

This will then generate the (invalid) urls and the preg_replace will remove any additional Index.php’s from the request URL as its already mentioned in the $base variable a few lines below:

...
if ( $wp_rewrite->using_index_permalinks() && ( $pagenum > 1 || '' != $request ) )
$base .= 'index.php/';
...

Once you make the change and upload the files, your “Older posts” will start working again. I’ll submit a patch to WordPress I’ve submitted a patch to WordPress Trac, now its just a wait and see what they say, in the meantime here’s a patch file if you don’t want to modify sources manually. If there any issues, post a comment

2. Microsoft releases IE8 Beta 1 and ASP.NET MVC RC1
3. Getting a Windows 7 Beta 1 Product Key

Windows Mobile was never touch friendly – and rightfully so, as the operating system was written for stylus usage as a primary goal,  then later HTC (via TouchFlo3D) bolted on a new UI to bring touch friendly UI candy for Windows Mobile. Though Windows Phone 7 brings this to the table (with touch being a primary design goal), I’m ashamed to say they’ve taken what WinMo was good for – being easy to customise and cook ROMs for and turned it to the Apple-esque closed ecosystem and Jobs likes being in control of his herd.

The great thing about the Android is that its got potential and its constant source of updates are very welcome (probably the fastest growth for a platform thus far!), the AppStore has increased exponentially the past few months (which is good and bad – useless app count increases) as users begin to crawl out of the rotting Apples and the stained Windows phones. Another key is that all your Google services are integrated nicely. I’ve given up most of my daily things to Google – email, calendar, contacts… They’re all “in the cloud” and (for now) synchronisable and safe (not that you couldn’t do this with the iPhone or Windows Mobile).

The next release of Android (2.2) is dubbed Froyo and brings some very funky new updates.

JIT Compiler

Probably the biggest addition in this release but first and foremost, the design and architecture of the Android platform is a bit different to others. Forgetting the native development paradigm for Android, you write applications utilising the Java language.

From the Android Developer Guide:

Android applications are written in the Java programming language. The compiled Java code — along with any data and resource files required by the application — is bundled by the aapt tool into an Android package, an archive file marked by an .apk suffix. This file is the vehicle for distributing the application and installing it on mobile devices; it’s the file users download to their devices. All the code in a single .apk file is considered to be one application.

In many ways, each Android application lives in its own world:

• By default, every application runs in its own Linux process. Android starts the process when any of the application’s code needs to be executed, and shuts down the process when it’s no longer needed and system resources are required by other applications.
• Each process has its own virtual machine (VM), so application code runs in isolation from the code of all other applications.
• By default, each application is assigned a unique Linux user ID. Permissions are set so that the application’s files are visible only that user, only to the application itself — although there are ways to export them to other applications as well.

It’s possible to arrange for two applications to share the same user ID, in which case they will be able to see each other’s files. To conserve system resources, applications with the same ID can also arrange to run in the same Linux process, sharing the same VM.

In order to achieve this, the Android platform uses the Dalvik Virtual Machine (which is register based as opposed to the more common stack based machines) suited for embedded devices – low memory footprint, run multiple VMs by offloading the process isolation, memory, threading and IO management to the operating system (Android).

The caveat with the Dalvik VM is that the performance is not ideal (it has no JIT compiler) and (by the looks of it) needs to improve garbage collection process (fragmentation is a concern currently). If you’re keen on understanding more about the Dalvik VM, checkout a talk from 2008′s Google I/O about Davik VM Internals (1:01:34). They also realise the performance implications of the runtime.

However, back in November 2009, Bill Buzbee commited the Dalvik JIT code to the Android platform bringing JIT compilation which (if you’ve been using any of the CyanogenMod’s lately) makes a very noticeable and welcome performance boost to all applications.

The (trace-based JIT) compiler detects frequently executed traces (hot paths & loops) and emits optimised code for the platform as necessary, ensuring that minimal heap memory is utilised without the use of any persistence storage – which is what you want in an mobile device!  Trace based JIT compilers are very common today, the TraceMonkey engine in Firefox is an example where dynamic languages (like Javascript) have had a boost through their use. Take a look at SPUR which is a Microsoft research project to bring trace-based JIT Compiler for CIL.

Whilst included in Android 2 it was never enabled, and by the looks of it, Android 2.2 will see this being enabled and stable

Linux Kernel update 2.6.32

The upgrade from 2.6.29 to 2.6.32 should bring a trimmed memory foot print and some performance tweaks as well as 802.11n support on devices such as the Google Nexus (yay!)

Flash 10.1 Support

There’s lots of hoo-haa about Flash support on iP*’s and other devices, I’m not too concerned about having it on my phone (less annoying ads browsing the interwebs) but it seems Google will bring Adobe Flash 10.1 support to Android. For some, it was a deal breaker when it came for choosing a phone. I guess now its a matter of ooh-ah!

Automatic application updates

Currently, updating Android applications is quite tedious – updating one application at a time, but it seems a newer update will automatically ensure that your applications are up to date – which is good and bad, I’d like to control when and where it decides to eat up my 3G data for updates (Eg. Update when on wireless)

Hopefully a rollback feature will also be implemented in case the newer versions break things.

Other updates

• OpenGL ES 2.0 enhancements which game developers will find enticing.
• The ability to control the color of the trackball (which currently flashes white)
• Enabling of FM Radio
• Fixes for resolution and “crazy screen” woes.

When will we be getting this? No-one knows, but suggestions are around the time for the Google I/O event on May 19th.

Next up, I’ll write about some of the applications that I’ve come to use daily, in the meantime you can see the apps running on my Android by checking my AppBrain account. Later some development articles on Android too
