For many systems administrators, choosing and managing a VPN system is often quite a headache. Inflexible clients, servers, and protocols often prevent VPN's from being smoothly integrated into an already functioning network. The fact that many VPN clients are installed on users' home computers, well out of the reach of the systems administration team, often means that troubleshooting and upgrading VPN systems is time consuming and a struggle for both admins and users.

Steve Jobs says analysts should stop worrying about market share and focus on profits. And moving the company beyond Macs could boost both. Yet Apple's market share has slipped inexorably. It dropped from 9.4% in 1993 to just 3% in 1997, the year Jobs was rehired to run the company. According to Gartner's preliminary market-share data, Apple held just 1.8% of the worldwide PC market in the fourth quarter of 2003. And some think Apple's share will fall further, if it can't keep pace with surging overall PC demand. In the meantime, the Street yawned when Jobs & Co. recently reported strong results, citing slack sales of the new G5 and ignoring plenty of good news.

This paper by veteran real-time instructor David Kalinsky provides an introduction to the subject of task scheduling, from the perspective of novice embedded systems software developers. It begins with a survey of simple "home-made" task schedulers. Then it introduces the concept of preemption and priority-based preemptive schedulers, as used in off-the-shelf real-time operating systems. It ends with a glimpse into deadline scheduling for hard real-time systems.

Daniel Stone writes over at Slashdot: "A short time ago, freedesktop.org xlibs 1.0 was released. Simply put, this is the collection of libX11, libXext, and other little-used libraries that kind of power your whole desktop. The xlibs team at fd.o are now maintaining all these libraries, and more, and we're going to be making releases as part of the fd.o platform, which is far more wide-ranging, but it still forms an important part of the platform. Share and enjoy!"

This study is going to be significant from the standpoint of OS development and the inability of governments to 'stem the flow of information'. Most, if not all, of the people in this survey want only a "turn key" solution for their computer activities.

Jayacard is the open source smart card operating system focused on contactless products. Some of the supported norms include ISO 7816-3/4/8, ISO 14443, ISO 15693 and x509. Current version is a cleanroom development that has been ported to some secure microprocessor under NDA ; but opensource roadmap is to have this software also freely available for flashable microprocessor like the ATmega161 from Atmel.
