This posting will describe how to change your default system browser on Windows XP to a portable version of Mozilla Firefox using a free program called DefaultBrowser, doing so reversibly and without installing the non portable version. The same process described here could be used to change your default browser to any portable (or non portable) browser.

There are many ways to check RSS feeds. Two of the most popular are using a local RSS client (such as RSSOwl) and using a web-based reader (such as Google Reader). This posting will present nine interesting (and at times unusual) free ways to check RSS feeds, including using dekstop widgets (KlipFolio), RSS feeds as tabs on the side of your screen (Stick), RSS feeds within a dockable desktop area (SideSlide), as desktop sticky notes (Note Mania), embedded in your desktop wallpaper (Chaos Wallpaper), as news-tickers scrolling across your screen (EasyDeskTicker), and delivered as emails in your inbox (FeedMyInbox).

This posting will describe how to split a very large CSV or Text file into a number of smaller parts by specifying the number of desired lines within each of the resulting pieces (for example, by 65536 lines for use with Excel 2003 or 1,048,576 for Excel 2007). The method described will use free software to do this and will work for very large files (even files larger that 4 gigs in size), will avoid loading the entire file into memory when processing, will maintain the format/extension of the original file, and will not add any additional information to the resulting files.

If you’ve ever encountered a blocked startup app in Vista and would like a work-around that can bypass it then read on. This posting will describe how to launch an app on startup as a scheduled task, which will circumvent the startup apps list altogether. Ultimately you will be able to get your app to launch without seeing the notice in the screenshot and without having to shut down Vista’s User Account Control security infrastructure.

Finally, a new theme. Although I liked the old Lightbreaker theme, I’d been wanting to move away from it for some time. After researching Wordpress themes for quite a long time (free and paid) I finally decided to go with the this one, Arthemia Premium (there is an excellent free version as well, which can be found here).

You might have noticed that I’ve not been able to post for a few days. The company I work for flew everyone in the office from Seattle to NYC for a company function on Thursday, and it was an opportunity to take my wife and kids along for a long weekend in the big city.
