The video below shows twenty-four hours from noon UTC to noon UTC on June 7, 2010 using webcams from the Catfood WebCamSaver database. It proves that I really will do anything to avoid finishing off the new Catfood web site.

The Volume Shadow Copy Service (VSS) takes a snapshot of an NTFS drive at a point in time. The clever thing about VSS is that it doesn't copy anything — it starts with the assumption that nothing has changed and then keeps track of every change to the snapshot so only changes need to be stored.
From Windows Vista on it's possible to mount a shadow copy as a drive letter or share. ShadowTask is a command line tool that creates a VSS copy, mounts it as a drive and then runs a program or batch file. For example:
ShadowTask C V dostuff.bat
Creates a copy of C:, mounts it as V: and then runs dostuff.bat.
Let's say you want to copy a locked file — maybe some outlook personal folders. Dostuff.bat could contain:
copy V:\Users\You\AppData\Local\Microsoft\Outlook.pst C:\Users\You\Desktop\OutlookBackup.pst
Bingo, you have a copy of your PST without shutting down Outlook.
Download: ShadowTask.zip (50.86 kb)
The ZIP contains both 32 and 64 bit versions of the tool. You must use the version that matches your platform. ShadowTask supports Windows Vista and 7. XP doesn't support mounting a shadow copy so ShadowCopy will fail if you try to use it on XP. ShadowCopy must run as admin (elevated).
PdfScan is a simple tool for scanning pages into a PDF file. You can scan single pages from a flatbed scanner or several pages from a document feeder. The page size applies to both the scan and the page(s) added to the PDF.
I wrote PdfScan because I know I'm going to be scanning a lot of documents over the next couple of weeks. Previously I used a tool called ScanToPDF from O Imaging but their licensing pissed me off so much that I'd rather waste time reinventing the wheel than pay them for another copy.

Download PdfScan-0.10.zip (260.77 kb).
This is a beta — it works with my scanner and my documents. There's no installer, so extract the ZIP file and run the EXE to use it. PdfScan requires the .NET 4.0 Framework. If you get an error when you run PdfScan.exe try installing .NET 4 and then run it again.
If enough people use this I'll make it a bit more friendly, add an installer and release it through Catfood. If you like it leave a comment below. If it doesn't work for you leave a comment or email me and I'll try to help.
PdfScan uses PDFsharp from empira Software. Thanks chaps!
Now here's a niche:

I'm occasionally jealous of an iPhone app, in this case a station finder for NPR. I hate hunting on a long drive or in a strange city. Luckily, NPR has an API, so I've whipped up an NPR Station Finder for Windows Mobile.
I've been busy updating a couple of Catfood products.
Catfood Earth updates your desktop wallpaper to show day, night and cloud cover. It can also display earthquakes, time zones, places and US weather radar:

Catfood Follower is a Twitter tool that automatically follows people who follow you and/or removes friends who stop following you. I think it's most useful for business accounts:

With these two out the door my next project is overhauling the Catfood website. I'm kind of dreading it, but the current architecture is over six years old and it's definitely showing its age.
