WiFi enabled my Roomba

A month ago I purchased my Roomba 780. At home we have a dog (German Sheppard) and we had to vacuum at least once a day (ok my wife did that :)) I thought; let me help a little in our household so I bought this device. At nights it automatically cleans the floor and when we leave the house we can manually start it as well by hitting the clean button or using the remote.

Nerd tracert

Ok I know I am a nerd but this is just funny 🙂 open a command prompt and run this command: tracert –h 100 obiwan.scrye.net it will result in this:

Where are all the Windows 8 apps?

We get a lot of questions from people they see less apps in the Windows 8 store than their friends and are wondering what’s going on. It’s pretty simple. By default the Windows 8 store only shows the apps which support your Windows Language preferences. So if you install a Dutch version of Windows the store only displays apps which support the Dutch language. There are 2 ways you can show more apps.

How to play a WAV sound file with DirectX in C# for Windows 8

Many people use the Mediaelement to play soundfiles in their apps. For my liitle app this wasn’t good enough. I build an app where I want to be able to press a button very fast and everytime a sound should be played. Mediaelement didn’t handle the soundplaying fast enough for me. On Windows Phone I could use XNA but that’s not available on Windows 8. The alternative is DirectX, since I don’t want to write any C++ code anymore I needed to find something else.

How to increase your Windows 8 app ratings

Today I described a trick for Windows Phone how to increase the numbers but also the average rating of your app. It worked very well for the my rubber duck app I wrote. A little over 11000 downloads with over 1000 reviews is a ratio of 1:11 which is very good. The trick is to ask people to review your app (and provide them a very simple way to do it) after they start your app 5 times.

How to increase your Windows Phone app ratings

UPDATED (18-1-2012): Jason mentioned in the comments this doesn’t work for Windows Phone 8. He is absolutely right. If you check the documentation on MSDN http://msdn.microsoft.com/en-us/library/windowsphone/develop/ms598674(v=vs.105) it tells you for Windows Phone 8 you can’t use the MessageBox.Show in the Application_Launching event. So you should place your code in the OnNavigatedTo event of your first page. I changed the code below to reflect that. One of the really important things people look for when looking for an app is good rated apps.

Making a backup of my HP EX470 Homeserver disk

Update: make sure you follow this post when finished cloning your drive otherwise WHS won’t run as you would expect. One of my colleagues Homeserver crashed and he doesn’t have the restore DVD anymore. I happen to have an EX470 homeserver from HP as well. My colleague asked to copy the C drive (that’s the only drive HomeServer doesn’t create a duplicate for). Lars Stolwijk recommended using EaseUS ToDo backup to clone a disk on twitter.

Little fun with NFC and Windows Phone 8

Since Windows Phone 8 supports NFC I wanted to see what I could do with it. I ordered a bunch of NFC stickers online from Special Line. You can use your own app to program the stickers but there are also a few in the store already. NFC Interactor or NFC Launchit. NFC Interactor is the most flexible but you need to do most of the configuration yourself. NFC Launchit has a lot of predefined action you can write to your tag (but only app launches) for example go to your wifi settings or Kid’s corner.

Youless and Bidgely in the house

Around the end of the year we will get the final calculations from our energy supplier and you will know if your monthly bill was too high or too low the last year. My energy bill is quite expensive I think and that has mostly to do with me using a lot of energy (and all the taxes of course). When I log in to the website of Eneco I can see what the average usage of houses in my neighborhood is.

About this blog, it’s wordpress running on Microsoft Azure

Why not describe how I installed this blog? Perhaps you are surprised I run this blog on WordPress while I am working at Microsoft 🙂 that’s ok but I like to play around with other stuff than just Microsoft technology. It helps me being informed about what people are also using (and yes I know not the entire world is using Microsoft technology) and WordPress actually runs perfectly fine on Microsoft Azure.
