This week at UniForum, AT&T’s Unix Software Operation will unveil a new Open Look release that promises to shrink the amount of memory needed to run it. Release 2 – for System V.3.2 and above – has been squeezed into 6Mb, down from the previous 8Mb. That’s reportedly enough to run the operating system, Open Look interface and its clients: the file manager, window manager and workspace manager plus two applications. Sources say the Software Operation’s development team over at Bell Laboratories improved on Massachusetts Institute of Technology’s Widgets to achieve the memory reduction and have dubbed their approach Flattened Widgets. The Operation is also expected to announce the controlled availability of its OSI Communications Platform, its Streams-based implementation of the mid and upper levels of the seven-layer Open Systems Interconnection protocol stack. This implementation of Levels 4 through 7 is not yet ready for general availability and will be offered initially only to developers such as Pyramid Technology Corp. First products could follow in May. In addition, Unix Software Operation is said to be coming out with the Graphics Service Revision 2 for Unix System V.4, a new iteration of its graphics extension including the new Open Look release, X/Win and X.11 News, with provision for Postscript output. Current customers will be given free upgrades. Bell Labs has tinkered with X/Win’s saveunder feature and have reportedly achieved 20% performance improvement.
