VirtualBox 3.2.0 Beta 1 Released!

May 3rd, 2010 No comments

Finally downloaded the latest 3.2.0 release of VirtualBox today and gave it ago!

From the forum post for this pre-release.

VirtualBox Version 3.2.0 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
  • 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)
  • 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 (see the manual for more information)
  • USB tablet/keyboard emulation for improved user experience if no Guest Additions are available
  • LsiLogic SAS controller emulation
  • RDP video acceleration
  • NAT engine configuration via API and VBoxManage
  • Guest Additions: added support for executing guest applications from the host system
  • OVF: enhanced OVF support with custom namespace to preserve settings that are not part of the base OVF standard

In addition, the following items were fixed and/or added:

  • VMM: fixed crash with the OpenSUSE 11.3 milestone kernel during early boot (software virtualization only)
  • VMM: fixed OS/2 guest crash with nested paging enabled
  • VMM: fixed Windows 2000 guest crash when configured with a large amount of RAM (bug 5800)
  • VMM: fixed massive display performance loss (AMD-V with nested paging only)
  • Linux/Solaris guests: PAM module for automatic logons added
  • GUI: guess the OS type from the OS name when creating a new VM
  • GUI: added VM setting for passing the time in UTC instead of passing the local host time to the guest (bug 1310)
  • GUI: fixed seamless mode on secondary monitors (bugs 1322 and 1669)
  • GUI: added –seamless and –fullscreen command line switches (bug 4220)
  • Settings: be more robust when saving the XML settings files
  • Mac OS X: rewrite of the CoreAudio driver and added support for audio input (bug 5869)
  • Mac OS X: external VRDP authentication module support (bug 3106)
  • Mac OS X: Moved the realtime dock preview settings to the VM settings (no global option anymore). Use the dock menu to configure it.
  • Mac OS X: added the VM menu to the dock menu
  • 3D support: fixed corrupted surface rendering (bug 5695)
  • 3D support: fixed VM crashes when using ARB_IMAGING (bug 6014)
  • 3D support: fixed assertion when guest applications uses several windows with single OpenGL context (bug 4598)
  • 3D support: added GL_ARB_pixel_buffer_object support
  • 3D support: added OpenGL 2.1 support
  • 3D support: fixed Final frame of Compiz animation not updated to the screen (Mac OS X only) (bug 4653)
  • Added support for virtual high precision event timer (HPET)
  • LsiLogic: Fixed detection of hard disks attached to port 0 when using the drivers from LSI
  • NAT: fixed ICMP latency (non-Windows hosts only; bug 6427)
  • Keyboard/Mouse emulation: fixed handling of simultaneous mouse/keyboard events under certain circumstances (bug 5375)
  • Shared folders: fixed issue with copying read-only files (Linux guests only; bug 4890)
  • OVF: fixed mapping between two IDE channels in OVF and the one IDE controller in VirtualBox

Bootilicious! Download links are on the site (updated for BETA2).

Some changes in .NET BCL 4.0

November 21st, 2009 1 comment

I’ve been porting a few products to .NET 4.0 and came across some cool new additions in .NET 4.0 which will be quite useful for developers.

Strings

Streams

Remember writing this before to copy one stream to another?

public static void CopyTo(this Stream input, Stream output)
{
byte[] buffer = new byte[2048];
while (true)
{
int read = input.Read (buffer, 0, buffer.Length);
if (read <= 0)
return;
output.Write (buffer, 0, read);
}
}

Now you don’t need to, just use the Stream.CopyTo() method.

inputStream.CopyTo(output);

Checking for 64bit-ness

Previously to detect a 64bit operating system you would either P/Invoke out and call the IsWow64Process in Kernel32, looked at the “PROCESSOR_ARCHITECTURE” environment variable or even easier (and completely managed code) way of checking the size of a Pointer.

public static bool IsWin64
{
return (IntPtr.Size == 8);
}
public static bool IsWin32
{
return (IntPtr.Size == 4);
}

Now you can simply use the Environment class that comes with two new properties.

WPF 4.0 Improvements

There are simply too many to list, see the article on ScottGu‘s blog about WPF4 and VS2010/.NET 4.0.

One very important tweak are the Text Rendering improvements that TextBlock‘s now have a new TextOptions.TextFormattingMode that greatly improves the quality of text rendering.

<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<StackPanel xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'
xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'>
<TextBox TextOptions.TextFormattingMode="Ideal" FontSize="11">ThushanFernando.com - Ideal</TextBox>
<TextBox TextOptions.TextFormattingMode="Display" FontSize="11">ThushanFernando.com - Display</TextBox>
<TextBox TextOptions.TextFormattingMode="Ideal" FontSize="16">ThushanFernando.com - Ideal</TextBox>
<TextBox TextOptions.TextFormattingMode="Display" FontSize="16">ThushanFernando.com - Display</TextBox>
</StackPanel>
</Grid>
</Window>

Here’s a pretty picture showing the difference between using Ideal and Display. The difference is noticable for text sizes below 15.

MainWindowAlternatively you can place it in the Window so all child controls will render nicely.

<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow - Display" Height="350" Width="525"
TextOptions.TextFormattingMode="Display">
<Grid>
<StackPanel xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'
xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'>
<TextBox FontSize="11">ThushanFernando.com</TextBox>
<TextBox FontSize="16">ThushanFernando.com</TextBox>
</StackPanel>
</Grid>
</Window>

There are LOTS more coming in .NET 4.0 that will make anyone doing .NET development today just wet their pants over, just read the article on MSDN by Justin Van Patten about Whats new in the BCL in .NET 4.0 and also posted on the BCL team blog.

Thunderbird 3.0 Beta 4 fixes corrupted summary files!

October 6th, 2009 No comments

Since ditching Outlook after Outlook 2003 (Outlook 2007, 2003 was fine in comparison) came around I’ve been using Mozilla Thunderbird as my ever faithful email client. Its fast, lightweight and not as bloated as Outlook is – couple it with Lightning and you’ll be laughing!

Thunderbird 3 brings some cool features for users with the biggest being tabbed message windows (and calendars etc). If you downloaded the new 3.x betas make sure you get Beta 4, the long standing issue with the Messagebox Summary file being corrupt has been finally addressed. Its been a pet hate for a long time now, sometimes searching a folder can corrupt an MSF (means having to go and remove the MSF so it rebuilds the index!), no more! Thunderbird will now fixup any problematic MSF files in the background, yay!

The search in Thunderbird 3 is a massive improvement over the other clients I’ve used, give it a go!

After you download Thunderbird, make sure you get the latest nightly for Lightning Calendar Addon and Google Provider and use them.

Yesterdays Undies: Microsoft releases Internet Explorer 8!!!

March 20th, 2009 No comments

A quick note that the once mighty beast that is Internet Explorer (affectionatley also dubbed, Internet {Exploder, Exploiter etc}) has released the much awaited version 8.

Internet Explorer 8 About BoxThere’s also a review on eWeek for IE 8 and an Exclusive interview on TechRadar with Microsoft’s John Curran.

Direct download links for your platform:

Grab it while its hot and add it to your list of browsers to test, or just use SuperPreview. UPDATE: we tried it, and our initial thoughts were it was lamey, stick to BrowserShots.

Whilst its downloading, checkout the History of the Internets, everything from the days of Marquees and annoying overdone GIFs, to the days where every fscking site had a flash video, to the brighter days of today, when we all seem to walk to stalk everyone else and see what they’re up to.

I’m running Windows 7 on this lappy so unfortunately you wont be able to install the RTM if your in the same boat.

In terms of security, unfortunately IE8 was defeated at Pwn2Own but not before everyones *favourite* fruit company’s Safari went down… in seconds for the second year in a row! Not even IE8 on Win7 was left out of the carnage.

Mmm I can taste those crApples rotting on teh Safari – they should add that to the list of security features.

Late for work, enjoy.
