Figure 2 Spotlight search results with Entourage items returned Double clicking on a returned item in Spotlight works as expected You see the Entourage item open just as if you had clicked on it in Entourage So what s going on under the covers Let s use some command line tools and take a look Query with Command Line Tools There are a number of command line utilities that we can use to query the Spotlight database We can use these tools to see where Entourage is storing the Spotlight metadata that it s creating and we can also see what the metadata files themselves look like The first tool to look at is mdfind mdfind queries the metadata store and returns the results of our query This tool takes three parameters The live parameter will continuously scan the database for results and you ll see items added as they come into Entourage The onlyin parameter allows us to specify a particular folder for the search Finally the query parameter a string representing the information that we re searching for Apple s developer documentation provides more details on the syntax of Spotlight queries Lets see if we can use this tool to find an Entourage item and see where the metadata is being stored Running the command mdfind welcomee microsoft com on my machine returns a result with the path WWW MACTECH COM Users Brianjo Library Caches Metadata Microsoft Entourage 200 4 Main Identity Messages 0T 0B
7. CRYPTO Server is also the first solution we have tested that supports two factor authentication for Apache Web servers via its CRYPTO Web component If you know of others please let us know Using CRYPTO Web we were able to secure a website and then authenticate to it with a configured token CRYPTO Web should make it a simple process for administrators to secure websites by requiring users to authenticate with their token in order to gain access Companies can also leverage out of the box interoperability with network entities that provide native RADIUS support Unlike CRYPTOCard s original OS X offering which only provided client side authentication the latest version of CRYPTO Server for OS X also provides enterprise ready functionality like High Availability which utilizes real time multi master replication functionality to ensure there is no single point of breakdown by switching to a replica server in the event of system failure This is important as it means that the authentication solution can now meet the security needs of any sized organization Another unique feature of CRYPTO Server is that it offers cross platform capability This is important news for the majority of organizations that employ heterogeneous network environments in which any combination of Windows Linux or OS X servers can support any client end user systems running on any of the three platforms Other useful CRYPTO Server features include RSA

83. RFACE IS SIMPLE AND STRAIGHTFORWARD Introduction Modern websites and web applications appear drastically different from sites on the web 5 and 10 years ago Tools like GoogleMail BaseCamp and TiddlyWiki have revolutionized the general concept of what a webpage can do and how users interact with it The days of clicking on a simple hyperlink to be taken to a new page or sitting and waiting for a form submission are rapidly dwindling The technology driving these sites is not really new but their application and use has only recently become widespread and supported by a majority of web browsers Furthermore many web developers feel daunted by the rapid pace of the changing techniques and don t have a clear understanding of how the technologies are implemented and used One of the most revolutionizing of these technologies has been dubbed AJAX or Ajax depending upon whom you ask Ajax is responsible for dynamic page content marking database entries and in line text editing without the need for page reloads or large complex plug ins like Flash or Java The goal of this article is to teach you the basics of Ajax and demonstrate that it is not as difficult a concept as it may first appear In reality Ajax is simple and easy for any web developer to add to their new or already existing site What is Ajax AJAX is an acronym for Asynchronous Javascript and XML The most important concept of AJAX is the asynchronous part Asynch

RdWrPerm does not guarantee exclusive file access on Mac OS X On Mac OS X subsequent Open calls to open a file with write permission may succeed without error Similarly the PBLockRange routines may not actually guarantee byte ranges that cannot be modified by other processes Because these routines may return without error you should check out the availability of exclusive file access 15 SAMPLER 2006 By Paul T Ammann see Checking Availability of Exclusive File Access before making any assumptions about the underlying file access If the supports advisory locks feature is not available your application will not know if the file is already in use by another application AppleShare servers and Personal File Sharing on Mac OS X do enforce exclusive file access and range locking for volumes accessed over the network However this functionality is only available when accessing files over a networked file sharing connection and is not available to applications running on the server itself Guidelines for Working with Non exclusivity You should realize that many applications relied on the behavior of the classic Mac OS File Manager to prevent multiple applications from writing to the same file or to control write access through byte range locking Since that behavior is not implemented in all versions of Mac OS X some common workarounds that you may wish to use in your code are described below BSD was designed w
