Andrew Tridgell developed the first version of Samba Unix in December 1991 and January 1992, as a PhD student at the Australian National University, using a packet sniffer to do network analysis of the protocol used by DEC Pathworks server software. It did not have a formal name at the time of the first releases, versions 0.1, 0.5, and 1.0, all fro...
Version 3.0.0, released on 23 September 2003, was a major upgrade. Samba gained the ability to join Active Directory as a member, though not as a domain controller. Subsequent point-releases to 3.0 have added minor new features. Currently, the latest release in this series is 3.0.37, released 1 October 2009, and shipped on a voluntary basis.The 3.0...
Some versions of Samba 3.6.3 and lower suffer serious security issues which can allow anonymous users to gain root access to a system from an anonymous connection, through the exploitation of an error in Samba's remote procedure call. On 12 April 2016, Badlock,a crucial security bug in Windows and Samba, was disclosed. Badlock for Samba is referenc...
Samba allows file and print sharing between computers running Microsoft Windows and computers running Unix. It is an implementation of dozens of servicesand a dozen protocols, including: 1. NetBIOS over TCP/IP (NBT) 2. SMB (known as CIFS in some versions) 2.1. Samba supports POSIX extensions for CIFS/SMB. The initial extension was CIFS VFS (CAP_UNI...
Samba TNG (The Next Generation) was forked in late 1999, after disagreements between the Samba Team leaders and Luke Leighton about the directions of the Samba project. They failed to come to an agreement on a development transition path which allowed the research version of Samba he was developing (known at the time as Samba-NTDOM) to slowly be in...

Jan 1, 2002 · There are two main categories of information in the ATSC PSIP Standard: system information and program data. System information allows navigation and access of the channels within the DTV transport stream, and program data provide the information necessary for efficient browsing and event selection.
ATSC 3.0 is a non-backwards-compatible version of ATSC being developed (as of May 18, 2016) that uses OFDM instead of 8VSB and a much newer video codec (instead of ATSC 1 and 2's MPEG-2). On March 28, 2016, the Bootstrap component of ATSC 3.0 (System Discovery and Signalling) was upgraded from candidate standard to finalized standard.
The ATSC Program and System Information Protocol (PSIP) is specified in standards document A/65, and provides extension to MPEG 2 for the identification of streams associated with a program and time of day information. It provides sufficient data for a program guide function, and is structured such that a broadcaster may provide data ...
