Last week i was working on TFSBuild using TFS Buildserver to build a java project and there was one major challenge managing TFSBuild.proj file created when build definition was done.

<target name=”copyFileToServer”>
<echo>::::::::copyFileToServer Example::::::::::::</echo>

In day to day life we used to download useful stuff from world wide web, sometime requirement to download sequence of files, one way is to do it manually by clicking individual links or automate the download using Curl.
Showing you that next, how we can do it.
grab Curl from : http://curl.haxx.se/download.html
Curl has the ability to set sequences (including with leading zeroes, and alphanumeric sequences) as part of the download command which makes it a lot easier. This is all covered in the man page so I suggest reading it for a complete understanding of the options available.

jQuery mobile is a framework build upload on jQuery and jQuery UI foundation, which is a unified, HTML5-based user interface system for all popular mobile device platforms. Now days jQuery becoming popular among mobile sites. In spite of bugs (couple of explained below) this should not put you off developing with the framework as no framework is 100% complete, it get improvements/enhancements on going with users feedback. One of the major factor why jQuery Mobile becoming popular is easy to learn, early adoption of jQuery mobile by mobile sites and a large range of online support, threads and documentation available. Almost all bugs we encountered are known to development team and they definitely will fix those in future releases.
Many of the bugs are unique to the older Android devices (like 2.2, 2.3), therefore with the recent news that Google Chrome is to become the standard browser on Android 4.0 and above means that, jQuery mobile will be more consistent and will offer gr8 performance across devices. Currently, mobile chrome is available through Android Market in Beta.
One interesting fact, was when I ran CSS3/HTML5 compatibility test on Android default browser I got approx 188 points whereas when ran on Chrome I got approx 300 points which means quite a lot improvement and support for new features introduces with CSS3/HTML5.
