Aussie Toilets app v1.2

Thursday, 21 April 2011

'Aussie Toilets' version 1.2 is now available in the Windows Phone marketplace. This is my Windows Phone 7 app that shows the nearest public toilets to your current location.

The latest release includes the April 2011 dataset, and significant performance improvements. Specifically, toilet locations should load almost instantly. So now if you're in a hurry to find the nearest public toilet, you'll be relieved (ha ha) to know you won't be kept waiting any longer than necessary.
I'm quite chuffed that 'Aussie Toilets' is currently sitting at no. 3 in the top selling apps of the 'Navigation' category in Zune. Not sure if this is just for Australia or global. So far I've had over 1,200 downloads, which isn't too bad at all.
PS. I have received a bug report from an Austrian user of Aussie Toilets – turns out I hadn't tested the app outside Australia! This may explain an issue I had with getting 1.2 passing the Marketplace requirements (as I assume the testing would be taking place in North America). So expect v1.3 very soon!

Update 24th April, 3.30pm
Version 1.3 is now available in the marketplace

The big Four Zero

Monday, 18 April 2011

Today I am 40 years old!

I know this because as you can see the in the photo below, I'm wearing a badge (made by my daughter) that says "40 years old" Smile

Yesterday I celebrated the occasion with family and friends at a picnic lunch in Belair National Park. The weather couldn't have been better and I think everyone really enjoyed themselves (I know I did).

Extra special thanks to my lovely wife Narelle who worked very hard to make it a fantastic day, Narelle's Mum & Dad for decorations, barbecue knowledge and other help, my Mum and Dad for having me in the first place Smile, my sister Fiona for putting together a wonderful birthday scrapbook, and my kids for helping with the games.

Renaming date-named folders using PowerShell

Saturday, 9 April 2011

Since I've been using the Windows 7 Import Pictures and Videos wizard to upload photos from our digital camera, we've used the directory naming scheme of YYYY-MM-DD. Prior to this, I'd written my own custom photo importer in C++ as I didn't like the naming schemes that Windows XP offered. Unfortunately I'd chosen YYYYMMDD instead.

I'm now consolidating all our digital photos onto our Windows Home Server. This makes them easier to browse on the big screen using Windows Media Center, and has the added benefit that they also get backed up to the cloud via a subscription to CrashPlan.

I discovered the downside to having the different naming schemes when you go to view the photos in Media Center – it displays the folders out of order because they don't all follow the same format.

PowerShell to the rescue:

cd \\homeserver\photos
dir | Where-Object {$_.Name -match "^\d{8}$" } | Rename-Item -NewName { $_.Name -replace "^(\d{4})(\d{2})(\d{2})(.*)", "`$1-`$2-`$3`$4" }

This finds directories matching the old naming scheme and renames them to conform to the new one.

My C++ importer imported all photos into a single folder, so to avoid overwriting the same folder if you imported twice on the same day, I would add a .0 (or .1 etc) to the end of the folder to ensure it was unique. There weren't too many of these though, so I dealt with them manually.

Free licenses for WP7 EQATEC Profiler

Friday, 8 April 2011

If you're a Windows Phone 7 developer, you may have come across Eqatec's Profiler. As far as I know, it's currently the only performance profiler that supports WP7 applications (Red Gate have indicated that they will support WP7 in 2011 Q4).

I've made use of Eqatec Profiler already, as there is a free version available, but with some restrictions (such as only profiling a single assembly).

Now in exchange for trialling their analytics product, they're offering upgrades to give you free licenses to the less-restricted versions.

As well as WP7, the product also support profiling regular .NET, Silverlight, Services, ASP.NET and even .NET CF.

I participated in the analytics evaluation and got 21 points which entitled me to a 'Professional' profiler license (normally $US399).

So what did I think of the analytics product? Well it seems quite solid, and didn't have any noticeable impact on my test apps. If you were selling software commercially then it might be of interest, but the price is prohibitive for those of us who have only released free software so far.

Windows 7 Boot to VHD

Monday, 4 April 2011

For my own reference, some useful resources about boot to VHD:

Following instructions from http://technet.microsoft.com/en-us/library/dd979534%28WS.10%29.aspx

Diskpart

create vdisk file=C:\VHD\test.vhd maximum=25000 type=expandable      select vdisk file=C:\VHD\test.vhd      attach vdisk      create partition primary      assign letter=v      format quick FS=NTFS label=VHD
exit

 

PowerShell:

PS C:\VHDs> .\Install-WindowsImage.ps1 -WIM D:\sources\install.wim

Index   Image Name
[1]     Windows 7 Home Basic
[2]     Windows 7 Home Premium
[3]     Windows 7 Professional
[4]     Windows 7 Ultimate

Done.

PS C:\VHDs> .\Install-WindowsImage.ps1 -WIM D:\sources\install.wim -Apply -Index 4 -Destination v:
Applying "Windows 7 Ultimate" to v:...
