vxref provides integration of the xref tool into vim. The xref tool is a cross referencing and refactoring tool with a free version available that parses C and Java code, and a paid version that parses C++. vxref brings solid auto-completion (as opposed to all sorts of flakey varieties such as omni-complete) and accurate code browsing with scope information to vim.
Google Map GPS Cell Phone Tracker allows you to track Android, iOS, Windows Phone, and Java ME cellphones using Google Maps. It has two parts, a server and phone clients. You have a choice of two servers, using asp.net and SQL server or PHP and MySQL. The server software allows you to view cellphone locations in realtime using Google Maps and store routes and view them later. The client applications send their locations to the website periodically. All four applications work properly in the background and are written natively on each platform.
