May 27, 2010 GMTThe Déjà Dup backup utility may not be the most powerful or flexible backup tool out there, but it does have its advantages. Its straightforward interface makes it dead-easy to configure backups, while the support for the Amazon S3 storage back-end is a boon for users looking for unlimited backup storage on the cheap. In addition to that, Déjà Dup supports incremental backups, and it can encrypt and compress data during the backup operation. Besides Amazon S3, Déjà Dup supports other types of remote storage, including FTP, Windows shares, WebDAV, and SSH. And you can use Déjà Dup to perform scheduled backups.To install Déjà Dup on Ubuntu, you have to add the project's repository...
May 21, 2010 GMTChecking whether a specific Web server is up and running is as easy as issuing the ping command in the terminal, but if you are looking for a more versatile tool that you can use while on the move, try httpmon for Android. For starters, this nifty tool lets you set up multiple monitoring profiles, which can come in handy when you want to keep an eye on several servers. Besides ping, httpmon supports other monitoring options, such as response time, response code, and specific header and content strings. Better yet, you can specify multiple criteria; for example, you can configure httpmon to ping a specific server and check its response time in one go. Creating a monitoring profile is as...
May 20, 2010 GMTAmazon S3 provides unlimited storage at low prices, which makes it an ideal solution for storing backups. But to make use of it, you need a piece of software that can actually interact with Amazon S3: create buckets, list the contents of a bucket, upload and download files, etc. And aws, a simple command-line utility written in Perl, is the perfect tool for the job. You might wonder why not use a GUI-based application like Jungle Disk? For two simple reasons: as a CLI-based tool, aws is light on resources and it can be easily scripted.Before you proceed, you should install the curl utility. On Ubuntu, you can do this using the sudo apt-get install curl command. Next, grab the latest...
May 14, 2010 GMTGoogle Reader is a mighty good feed aggregator with a boatload of useful features, but its traditional two-pane interface has some room for improvement. And the FeedSquares extension for the Google Chrome browser represents a bold attempt to rethink the way you read and manage RSS feeds. The basic idea is pretty simple: the extension displays all feeds from your Google Reader account as colored tiles on a wall. Each tile (or square) shows the name of the RSS feed and an unread count. Click on the square, and all articles in the feed pop up at the bottom of the window. Click on the article you like, and it opens in a preview window. You can then read the article's excerpt as well as share...

May 07, 2010 GMTWhile it is possible to upgrade Ubuntu 9.10 to the latest 10.04 Lucid Lynx release, a clean install is the best way to go if you want to avoid update headaches.

May 05, 2010 GMTWhether you want it or not, your Web activities are tracked and analyzed in many different ways. But you don't have to put up with this, especially if you are using Firefox as your primary browser. There are a few handy Firefox extensions that can beef up your favorite browser's privacy features. Here are my three personal favorites.Besides regular cookies planted in your browser by many Web sites, some services add so-called Flash cookies or Local Shared Objects (LSO). Similar to conventional cookies, LSOs collect and share information about your Web usage. But unlike good old cookies, LSOs are particularly difficult to purge from your browser.
