You can get decent photos out of a standard, consumer-grade digital camera, but a little post-processing can turn them into fantastic wide-angle landscapes. You don't need to be one of those people who can explain the concept of lateral chromatic aberration to get truly eye-catching digital pictures. With a few shutter clicks and some free, cross-platform software, you can easily mesh standard digi-cam shots into true landscapes, fix one photo's deficiencies with another, and create layered photo collages. Let's take a look at how to use the free, open source application Hugin to make two basic kinds of panoramas.

The Digital Inspiration blog has a timely step-by-step tutorial on creating a "slipstreamed" Vista installation DVD that has all the fixes and tweaks from Service Pack 1 included. The guide utilises the previously mentioned vLite tool, and requires a Vista installation CD—but you create the new DVD from inside your existing Vista install, so don't get too format-happy before reading through. For a similar method of creating an updated XP installation CD, check out RyanVM's Update Pack.

Windows Vista only: Shadow Copies, an automated file version saver built into all copies of Windows Vista (and enabled by default), isn't a complete backup solution, but it could be a life-saver in certain situations. As The How-To Geek blog points out, however, it's pretty hard to find, let alone extract files from. Luckily, a forum member at the Geek's site has posted a complete tutorial on accessing and recovering previous file versions using the free utility ShadowExplorer. Using ShadowExplorer requires a good deal more clicking and searching than Apple's Time Machine, but it's a good solution for those "Oops, I forgot to back up ..." moments. Hit the link below for instructions and screenshots.

We've shown you how to disable Windows Vista's secure-but-really-annoying User Account Controls feature (a.k.a. the "A program needs your permission ..." pop-up) using Vista's settings and tweaking apps, but reader Kel points us to a way of disabling that prompt for specific applications. The trick involves downloading a Microsoft utility and clicking through about a dozen prompts, but it really does work, and you can keep your security settings just where they are while removing a major annoyance. Here's hoping Microsoft includes this kind of app-by-app disabling in their upcoming Service Pack 1.

As you might have seen in our comments, our readers love them some Pivot Tables, an aggregation tool that can show your spreadsheet data any way you tell it to. If you've felt left off of the data-wrangling bandwagon, the Productivity Portfolio blog has a guide walkthrough explaining the benefits and features of the tables and setting up a simple voting analysis table for an example. Better yet, the post includes a printable PDF for your do-this-when-I-get-home convenience. For more Excel 2007 knowledge, try out PP's equally helpful guide to AutoFilter.

Now that Leopard's long since dropped and the masses have seen the simple power of Time Machine, it might be a good time to take another look at similar solutions for other systems. Luckily, the Howto Forge has posted a helpful step-by-step through installing and configuring TimeVault, an integrated backup solution for Ubuntu and Debian-based Linux distributions. The tutorial walks through the process on an Ubuntu system, but would likely help other GNOME-based systems get most of the way there. If you're more the DIY, terminal-hacking type, you can always use cross-platform solution rsync to get the job done.
