|  | Conference Activities & Services Student Stipends Available The USENIX student stipend program covers travel, living expenses, and registration fees to enable full-time students to attend USENIX meetings. Detailed information about applying for a stipend is available at http://www.usenix.org/students/, by reading comp.org.usenix or sending email to students@usenix.org. Conference Proceedings One copy of the proceedings is included with your Technical Sessions registration fee. To order additional copies, contact the USENIX Association at 510.528.8649, or sending email to: office@usenix.org. Tutorial Notes Some tutorial notes may be available for sale after 3:00 pm on-site each day. Check with the registration desk staff. Poster Sessions & Demos Thursday, September 17, 5:00 - 7:00 pm Posters, which describe small projects or preliminary results, will be displayed during a special session on the second day of the technical program. During that session, attendees will have a chance to view the posters and talk with the authors about their work. Since some projects are better explained by running informal demos on a live machine, during the poster session space will be made available for informal demos. If you have a commercial product or a project that you'd like to show off, bring your laptop and sign up for demo space. Slots are available on a first-come, first-served basis starting in August 1998. Send poster submissions to tcl98papers@usenix.org. Sign up for informal demonstrations at http://www.tclconsortium.org/tcl98/demos.html. Birds-of-a-Feather Sessions (BoFs) Wednesday, September 16, 9:00 pm - 11:00 pm Thursday, September 17, 8:00 pm - 11:00 pm Do you have a topic that you'd like to discuss with others? Our Birds-of-a-Feather Sessions may be perfect for you. BoFs are very interactive and informal gatherings for attendees interested in a particular topic. Schedule your BoF in advance by telephoning the USENIX Conference Office at 714.588.8649, or email to: conference@usenix.org. ### SCHEDULED BOFs #### Wednesday, September 16 9:00 pm - 10:00 pm [incr Tcl] - Object-Oriented Programming Michael McLennan, Bell Labs Innovations for Lucent Technologies [incr Tcl] adds object-oriented support to Tcl in much the same way that C++ augments C. The new itcl3.0 release is a dynamically loadable extension that will plug-and-play with the Tcl/Tk 8.0.3 core. It supports Tcl namespaces and the Tcl byte code compiler. In this session, we'll talk about the features of this new release, and attendees will be able to ask questions and provide feedback. #### XML, DOM, and Tcl Steve Ball, Zveno Pty Ltd. The "XML, DOM, and Tcl" BoF will cover all developments of tools for handling XML documents using Tcl, including TclXML, TclExpat, TclDOM, and CoST. The current status of tools, applications using them and potential applications will be discussed. Future development of XML support for Tcl is an important aspect for attendees, especially coordination of development effort. #### Thursday, September 17 8:00 pm - 9:00 pm Dview - A Fast Scripting 3D Graphics Language Patti Koenig, Jet Propulsion Laboratory Dview is a text string 3D graphics language whose syntax enables rapid construction of articulated models, real-time control, key-framed control, import and export of geometry information from VRML 2.0 file format, export of animations to VRML 2.0 animations, and sequenced image export to Gif and Iris format enabling creation of images, QuickTime or MPEG movies. Dview is currently available on all OpenGL platforms with a second compliant Java3D implementation already under development. TCL programmers who need a scriptable, real-time 3D graphics engine layered on top of OpenGL or Java3D with VRML compatibility should love this TCL extension, scriptable 3D graphics language. The graphics engine can be downloaded via a free clickwrap license on the Dview Web site - http://dview.jpl.nasa.gov. #### Threads and Tcl Colin McLeod, Intrasoft SA This BoF is for anyone interested in the use of Tcl with multi-threaded programs. We can discuss: experience, successes, failures, problems implementations, Tcl81.a2, PtTcl, others? advocacy, does threading belong in Tcl at all? full/lightweight support? scripts level access? future development. #### 9:00pm - 10:00pm The TclHttpd Web Server Brent Welch, Scriptics Corporation TclHttpd is a pure-Tcl implementation of a web server with many interesting features. You can embed the server into your Tcl application to create URLs that map into direct calls into your application. Another feature of the server is HTML+Tcl templates for sophisticated server side generation of pages. This provides a nice way to do standard page structures, as well as a framework for sophisticated forms processing. TclHttpd is cropping up in many diverse applications. Join us to share your experiences. #### MacIntosh Tcl/Tk Underdogs Mark Roseman, TeamWave Software Ltd. This BoF provides a chance for enthusiasts fo Tcl/Tk on the MacIntosh platform to gather and share their experiences, woes, hopes, and dreams regarding Tcl/Tk on the Mac. We'll talk about how to move the Mac port forward, identify critical issues, share solutions, works in progress, and plot further strategies. Join us immediately afterward for drinks to thank Jim and other heroic MacTcl volunteers. Work-in-Progress (WIPs) Thursday, September 17, 4:00 pm - 5:00 pm The Work-in-Progress session will consist of five minute presentations. Speakers should submit their contact information and a one or two paragraph abstract to the WIPs registration web site: http://www.tclconsortium.org/tcl98/wips.html. Slots will be allocated on a first-come, first served basis; a few slots will be held open for on-site reservation at the conference. A schedule of presentations will be posted at the conference by Noon on September 17. Experience at other conferences has shown that most submissions are usually accepted, provided that time is available. The five minute time limit will be strictly enforced.
