PowerShell Directory Clean Up Script

Just a quick post of a PowerShell script I leveraged to clear out a directory of files older than 7 days. Props to Jeffery Hicks.
powershell.exe -command "Get-ChildItem 'C:\Temp\' -recurse | where {$_.LastWriteTime -le (Get-Date).AddDays(-7)} | remove-item -recurse"
Tack on a -whatif to the end of the script to see what would be affected without actually executing the action. Very powerful. PowerShell. Solid PowerShell cheat sheet here.

Starting a New Blog with my Cousin

On 9/15/2006, my cousin (he's really a 2nd cousin many times removed...I'm not convinced we're actually related ;-) John Ingrisano and I will launch a new blog targeted to the small business owner. He'll provide most of the content and I will provide the technical and marketing expertise. Ok, ok, starting a blog isn't rocket science but we're aiming to [eventually] derive some sort of profit from this venture, so I plan on doing this right. The two blogs I currently maintain live on the free Blogger.com and LiveJournal.com. I'll be covering the adventure here on Effective Thoughts--providing insight as to what worked and what didn't.

Switching the Parents to Ubuntu...?

I spent a half hour or so recently on the phone walking my Mom through a technical issue. Tentatively, I diagnosed her issue as a hard drive failure. She brought it over on her last visit and sure enough, the Dell XPS 450 from circa 1999 sounds like a bad coin-operated laundry at full capacity. I was aghast to discover she's running Windows 98. Ugh. Also, her recovery disk is just that--for recovery. I don't believe I'll be able to re-install Win98 on a new hard drive. That, coupled with the end of Microsoft (and Dell) support for Win98, got me thinking about Linux. (and she's not intense about her computing needs...and she doesn't want to spend much money...) I've been reading good things about switching one's parents to Ubuntu. Any thoughts out there?
