The Dark Energy Survey Collaboration has completed construction of the Dark Energy Camera (DECam), a 3 square degree, 570 Megapixel CCD camera which will be mounted on the Blanco 4-meter telescope at CTIO. DECam will be used to perform the 5000 sq. deg. Dark Energy Survey with 30% of the telescope time over a 5 year period. During the remainder of the time, and after the survey, DECam will be available as a community instrument. All components of DECam have been shipped to Chile and post-shipping checkout finished in Jan. 2012. Installation is in progress. A summary of lessons learned and an update of the performance of DECam and the status of the DECam installation and commissioning will be presented.

The Dark Energy Survey (DES) is a 5000 square degree survey of the southern galactic cap set to take place on the Blanco 4-m telescope at Cerra Tololo Inter-American Observatory. A new 500 MP camera and control system are being developed for this survey. To facilitate the data acquisition and control, a new user interface is being designed that utilizes the massive improvements in web based technologies in the past year. The work being done on DES shows that these new technologies provide the functionality and performance required to provide a productive and enjoyable user experience in the browser.
