Pete Brown's Blog (POKE 53280,0)
Pete Brown writes on a variety of topics from XAML with the Windows Runtime (WinRT), .NET programming using C#, WPF, Microcontroller programming with .NET Microframework, .NET Gadgeteer, Windows on Devices, and even plain old C, to raising two children in the suburbs of Maryland, woodworking, CNC and generally "making physical stuff".

I stopped into Best Buy yesterday and picked up something I had
been considering toying with: a LEAP Motion. This is
an interesting little $79 device which turns the airspace at your
computer into a live space for interaction. It recognizes all ten
fingers on your hands, differentiates between left and right hand,
open and closed, and can read the pitch, roll, and yaw of your
hand, pinc...

Like many of you, I spend the majority of my day on a desktop PC.
My PC happens to have two 30" displays, neither of which is touch,
and a Logitech Touch Pad that has some basic gesture recognition.
It's a giant water-cooled, overclocked beast that I built in 2010
(and upgraded video since then) and which still beats many new PCs
sold today. This particular PC has been upgraded from Wind...

In this post, I'll cover the migration of this web site from a
long history of local hosting to Widows Azure Web Sites.
I've had my own personal domains (GroupLynx.com followed by
irritatedvowel.com followed by 10rem.net) since the mid 90s. Early
on, I used regular hosts. I've run my personal website out of a
succession of servers in my basement for at least a decade. It used
to b...

If you're a Windows Phone (or iOS or Android) user and want a
smart watch which you can program using .NET, then get into the AGENT watch kickstarter before it ends in just
4 days.
You may know Secret Labs from their most popular NETMF product,
the Netduino. I've always been a huge fan of their stuff.

Secret labs has always made community a core part of their

I've put up a few videos and music tracks lately. Enjoy (view on
my site to see the videos. They don't usually appear in RSS
readers)
Also
"Pete plays with arpeggiators". Video created in After Effects and
Premiere Pro. The background video is a survey of the lights in my
home office one evening.
Inspired
by a little board called the "Tune in Tokyo". Vi...

Look what just arrived at the door!
The author copies are usually in the first set to be sent out.
For folks who have pre-ordered paper copies, you should see those
really soon. The ebooks typically show up shortly afterwards.
Yes, this is Windows 8 XAML in Action. We renamed the
book to better cover its ongoing focus.

Studio, Electronics, General Maker stuff, and more. If you have

A large number of apps in the Windows Store follow the "bunch of
boxes in a GridView" approach to the hub screen.
This can work in some cases, but I encourage developers and
designers to move beyond that look, and consider either evolutions
of it, or completely different approaches.
Boxes 1.0
For many, the basic box layout is a very workable layout. Here's
one of my essential app...

It seems that each generation is exposed to more mature or
serious situations at earlier ages than the one before it. There
are a lot more ways for kids to get in trouble online than just
running afoul of the creepily mustachioed basement dweller you see
on "that" episode of Special Victims Unit.
tl;dr: A child was banned from Xbox live and that caused me to
investigate some things ...

.NET 4.5 quietly introduced several attributes which are useful
for debugging and error reporting: CallerMemberName, CallerFilePath
and CallerLineNumber, all collectively referred to as "Caller Information". One of those,
CallerMemberName, is also very useful for MVVM apps and other apps
using INotifyPropertyChanged for change notifications.
Getting the calling function name

A common cause of Windows Store app certification failures is a
missing or insufficient privacy policy. Many don't realize that a
network-enabled app must have a policy, or if they do, don't
realize exactly what needs to go into it. In this post, I'll talk
about some of my observations regarding what makes for a good
privacy policy for a Windows Store app.
IMPORTANT: This is neither...

I'm working on a Windows 8 synthesizer app using XAudio2 and a
C++ + DirectX/XAML Windows Store app for Windows 8. As part of
this, I thought it would be fun to add a simple bit
crusher effect with included sample rate reducer. The point of
this effect is to make samples sound like they came from older
machines with lower bitrates and sample depth. To do that, I had to
do two things to ...

I recently did some work on my MikroElektronika ARM development
board. This was the first time I fired up the board on my
Windows 8 system. Everything in the IDE worked fine until I tried
to do some deploying and debugging on the board itself. It was then
that I realized the board's driver wasn't correctly installed. I
looked in the device manager and, sure enough, the board had the
lit...

I have a few pieces of analog gear which either don't support
MIDI, or simply work better with voltage control. This makes
including them in a sequence difficult as timing of arpeggios or
sequences will drift away from the rest of the performance. Not to
mention that synchronizing them by ear is not a simple task in any
case, and impossible to do in real-time if you want to adjust the
t...

I recently upgraded my main desktop PC to Windows 8. When I did
that, the Microsoft LifeCam software stopped working. It was
recognized as incompatible with Windows 8. For most people, this is
not an issue, as it works perfectly fine with the built-in Windows
8 camera app.
For me, however, I need a small camera app sitting on my desktop
so I can see the hallway leading to my office. I...

At Build, the Surfaces used by Jordan Rudess (and later provided
to Jordan and his tech Gianluca Trombetta, just like we did with
other Build attendees) were set up in advance with local accounts
rather than Microsoft accounts. This made it easy for me to have
everything ready for when Jordan took the stage.
One thing both Jordan and Gianluca needed to do to make the
Surfaces their ow...

My WPF talk from Build 2012 is live at
Channel9. Slides are available via that link as well.
I cover a few of the more interesting features in WPF 4.5, as
well as techniques for using Portable Class Libraries (PCL) to
share code with Windows 8 app.

My son is 6 1/2 and my daughter is 4. Today, my wife had some of
my children's homeschool friends over. One of them is a 10 year old
boy.
He saw Windows 8 on my 6yo son's laptop upstairs and said "You
have Windows 8?!?". He was very excited because he didn't have it
yet himself. He started telling my son all about Windows 8 and
what's coming. This is a 10 year old boy, mind you.

Privacy is a huge concern to most customers. Part of the Windows
Store app certification process includes checking for the presence
of a privacy policy if your app declares any capabilities which
could affect privacy.
MSDN has a section (4.1.1) explaining what is expected
from the privacy policy. I won't quote it here, but some important
points jump out (emphasis mine):
Declaring...

At several recent events (VSLive Redmond, thatConference, the
Heartland Developer Conference and more), I've had a neat little
.NET Micro Framework robot with me. The remote control for the
robot is a Windows 8 tablet running a simple Modern UI/Windows
Store app I wrote in C#/XAML. The example shows both how you can
use C# skills to build robots, and also how flexible the new
Windows St...

I've posted a few videos lately on YouTube. Here they are,
