Did you check if Hyper V is supported by your hardware ? you can read this to get an idea about how to check, that might be the cause

i used advance recovery companion automatic and manual detecting. No feedback from this SW. If i try to reset hololens in a device manager there isnt a hololens recovery device
For this one, best advice is to open a direct support ticket with Microsoft for hardware support:
aka.ms/HLSupport
The Microsoft support team can validate the hardware and assist further.
Thanks,

How to get started (Build) Presto on Windows

I see clear requirements that for building presto you need Mac OS/Linux.
https://github.com/prestodb/presto
I also see there are issues which are being discussed on getting windows support for Presto's build
https://github.com/prestodb/presto/issues/2351
What I don't see is a proper documentation of how to get started or a way around to get started with windows.
I found this link http://wheresthedocs.blogspot.com/
but I am not sure is it going to help me in getting started with presto.
If anyone has done it please provide with some basic instructions that would be very helpful!
Presto does not currently support building or running on Windows. There is a community member slowly working on getting this to work, but it is not something Facebook is working on.
In the mean time, I suggest you use Vagrant or VirtualBox to run virtualized Linux on your Windows machine.
Someone at Microsoft got this working on Azure last year with a few tweaks. http://blogs.msdn.com/b/mostlytrue/archive/2014/08/12/more-blue-coffee-presto-on-azure.aspx

ExpanderView port to Windows Store Universal App

As the title indicate, i'm trying to port ExpanderView from windows phone toolkit and use it with windows store universal app ie. WinRT. After re-writing all the necessary classes from Phone:Toolkit into my app, I just founded that the Header of the ExapnderView is neither showing in design mode or in debug mode.
Can't find out what is the problem with this. Is there anyone who tried the same thing and have a solution? I attached the the classes so you can take a look on it, if you can.
Expander RT codeplex
Just found out what the problem was. I missed the style xaml that targets the ExpanderView. If anyone is intresseted in this control for WinRT, both windows 8.1 or windows phone 8.1, please pm me and I will send you the files.
EDIT***
You can find the full Project in codeplex using this link ExpanderRT

Android emulator constantly rebooting on Ubuntu Maverick

and thank you for your time.
I am using Titanium Appcelerator to write an app for Android, and as compared to Windows, where the emulator was quite stable, in Linux I get the following symptoms:
emulator restart with no reason, sometimes after a runtime error, sometimes right after launching my app, and sometimes just right after booting completely after being launched
emulator informs that "process $1 is not responding", where $1 is generally the system process, but sometimes may be acore, or the calendar. This may happen while installing my app on the emulator, right after loading it, or right after unlocking the screen.
As it is easy to imagine, testing code like this can be quite difficult, so I was wondering, has anyone else stumbled upon this problem, and/or know how it could be solved?
Thank you very much in advance, and pls let me know of any info I should provide.
Leo
You should verify that the emulator is working fine without Appcelerator first. Definitely update to the latest SDK (r8) and create a new emulator AVD and see if the problem is there without Appcelerator.
I think I found a solution, but I don't claim it is universally valid: I just erased the virtual device created under Titanium, changed the project file for it to use SDK 1.4.2, and had it launched again under 1.4.2. It certainly didn't build my app, but at least it created a new virtual device, which I use now to build against 1.5.0, working like a charm so far.
Thanks again Manfred for pointing me in the right direction!
