Dalesa - 1.1

We were able to release version 1.1 of Dalesa roughly after eight months from the first release of Dalesa (version 1.0.0-rc1). Version 1.1 is now available for download at From 1.0 to 1.1 Dalesa greatly improved it's usability. The major change visible to the user in 1.1 is new standalone user interface provided for GNOME and KDE interfaces coupled with the Dlaesa cache (Dcache) with D-Bus. By using the interface users can now setup Dalesa with few clicks and skim through networked caching statistics effortlessly using temporal graphs displayed on the main window.

New Dalesa UI displaying networked caching statistics.

Major changes in version 1.1 includes
  1. Shifting from MySQL to embedded - MySQL database environment.
  2. Providing an API for external applications to communicate with the configuration component/statistics reporting component of Dalesa cache through D-Bus.
  3. Implementation of a dynamic URL elimination list that avoids useless cache lookups initiated by recurrent AJAX calls (ie:- GMail web chat application periodically makes HTTP requests to the origin server which produce responses which are not cache-able, Dalesa can now dynamically identify such URLs and avoid execution of P2P lookup algorithm on those).
  4. Removal of web based UI (version 1.0).
Previously Dalesa was released as a source package only (1.0). From this release (1.1) on Dalesa will be released in binary packages as well. Version 1.1 can be downloaded as Debian packages for Ubuntu 9.10 and 10.04. KDE user interface which is dubbed as KDalesa will be released as a separate binary package in few days for KDE users.

@Asith, thank you for encouraging us. I recommend you to install version 1.1.1 instead of 1.1.0 which will be released in few hours due to reasons given below.

1.) The version 1.1.0 cannot be configured in Linux systems with ReiserFS (no issue with BtrFS, EXT2/EXT3/EXT4). Truck has already been fixed and we will be releasing version 1.1.1 in few hours with this fix.
2.) If you are a KDE users then version 1.1.1 is much better as it comes with a separate KDE interface (packaged in a separate binary package).

Security: Privacy is guaranteed (middle man wont be able to know what sites you are accessing), but cache poisoning is possible.
