Here Ext is taken in the abelian category of sheaves of abelian groups on X, and is the sheaf of locally constant-valued functions. For a commutative Noetherian local ring R with residue field k , Ext R ∗ ( k , k ) {\displaystyle \operatorname {Ext} _{R}^{*}(k,k)} is the universal enveloping algebra of a graded Lie algebra π*( R ) over k ...
ext was the first in the series of extended file systems. In 1993, it was superseded by both ext2 and Xiafs , which competed for a time, but ext2 won because of its long-term viability: ext2 remedied issues with ext, such as the immutability of inodes and fragmentation .
Ext JS version 2.0 was released on 4 December 2007. This version was promoted as providing an interface and features more similar to those traditionally associated with desktop applications. Also promoted were the new user documentation, API documentation, and samples. [12] Ext JS 2.0 did not provide a backward compatibility with version 1.1.
Ext, ext or EXT may refer to: Ext functor, used in the mathematical field of homological algebra; Ext (JavaScript library), a programming library used to build ...
ext4 (fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3.. ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance improvements.

The ext file system solved the two major problems in the Minix file system (maximum partition size and filename length limitation to 14 characters), and allowed 2 gigabytes of data and filenames of up to 255 characters.

The exact definition, giving the criteria for deciding what part of the file name is its extension, belongs to the rules of the specific file system used; usually the extension is the substring which follows the last occurrence, if any, of the dot character (example: txt is the extension of the filename readme.txt, and html the extension of ...
