China Launches World's First Pulsar Navigation Satellite (ibtimes.com)

hackingbear writes: After launching the world's first quantum communication satellite this year, China today successfully launched the world's first pulsar-based navigation satellite (Warning: may be paywalled, alternate source), which will conduct in-orbit experiments using pulsar detectors to demonstrate new technologies. The X-ray pulsar navigation satellite XPNAV-1 was sent skyward at 7:42 AM (local time) atop a Long March 11 solid-fueled rocket from the Jiuquan Satellite Launch Center in China's northwest. China's new system is expected to be a significant improvement over the earth-based systems currently used by spacecraft as it would eliminate the time delay with sending signals back to Earth and processing.

Project 'MAT' Seeks New 'Leadership' (2016-11-11)

[Anonymous Coward]

MAT, "composed of a GUI application, a CLI application and a library, to anonymize/remove metadata," is a very useful tool[1] found in Tails[2] Linux and in the Debian Packages.[3]

MAT leader, 'julien voisin'[4], said on the MAT mailing list[5], "If someone wants to take over the maintenance/leadership, I'll be happy to do my very best to help him/her."[6]

MAT has been under scrutiny recently, including a web page which says, "We took a closer look at the Metadata Anonymisation Toolkit and found a security problem."[7], in Debian Bug reports "mat doesn't remove metadata in embedded images in PDFs"[8],[9],[10], lists,[11] and a recent Debian Security Advisory[12]:

"Hartmut Goebel discovered that MAT, a toolkit to anonymise/remove metadata from files did not remove metadata from images embededed in PDF documents. For the stable distribution (jessie), this problem has been fixed in version 0.5.2-3+deb8u1. This update disables PDF support in MAT entirely. We recommend that you upgrade your mat packages."

On jvoisin's blog, "The current version has bugs, and doesn't work on Python3, I wouldn't advise anyone to use it"[13], "developers: if you want to maintain MAT, I'll be happy to do my very best to help you, but I don't feel like reviewing and merging patches, sorry."

Please say a kind word to jvoisin and if you have the skills and ability, arrange with jvoisin for a clean transition of leadership so MAT doesn't end here.
