The Senate Appropriations Subcommittee on Defense has restored $821M of the $900M House cut in university research. (The final budget will likely be a compromise.) Chairman Daniel Inouye (D-HI) received more letters about the cut than any other item in the $243B defense budget. However, AP reports that ranking minority member Ted Stevens (R-AK) said it is "ludicrous and arrogant" for universities to feel they are entitled to Pentagon money every year.

Bill Park.] (If you can't attend, there are plenty of books and magazine articles on marketing your inventions. Try your library or the above sponsors.)

NIST has issued a broad-area announcement (BAA) soliciting $10K-$50K proposals on multiuser shared environments (MUSEs) as text-based user interfaces for distributed manufacturing. "The general problem is to present the relevant information, at the appropriate level of detail, to remote decision-makers at many levels in such a way as to allow them to interactively examine remote situations, and to cooperatively control the remote environment in real-time." Graphics and virtual reality techniques are also being studied, primarily for the control of equipment. Program contact is Dr. Ernest W. Kent, (301) 975-3460; contractual info from Diane Loeb, (301) 975-6399, NIST Acquisition and Assistance Div., Building 301, Room Bll7, Gaithersburg, MD 20899. [SOL/BAA 52SBNB4C8231, 6/13/94. Tim Finin.] (Proposals were due 7/29/94, but may be accepted through 6/9/95. Anyone know how I can get these BAAs earlier?)

The Clinton Administration has decided to limit its Clipper push to voice communications (and only after additional months of study), and that future encryption standards will be voluntary, unclassified, and exportable. Private key escrow may also be permitted. [Stanton McCandlish (mech@eff.org), alt.privacy, 7/21/94. Chuck Morefield.]

Silicon Graphics CEO Ed McCracken says that entertainment projects now drive graphics technology. Five years ago it was military, intelligence, and perhaps space applications. [Upside, 8/94, p. 32. EDUPAGE.]

Consumers are unhappy with half the CD ROMs they buy, returning as many as 20% as slow, boring, or buggy. [WSJ, 7/6/94, B1. EDUPAGE.] (Several caching and indexing programs are available to greatly speed up CD ROM sessions. Mac users can buy CD AllCache, CD-ROM ToolKit, or Rapid CD for about $46-60.)

Rocket Science Games Inc. found a way to speed up CD-ROM interaction. Now Times Mirror is buying a $5M stake in the technology, for its non-fiction CD ROM products. [WSJ, 7/27/94, B5. EDUPAGE.] (Want to be rich? Solve problems that need solving.)

Britannica Online is in beta test as a WWW service, with commercial availability planned for 9/94. Check http://www.eb.com/about.html for info; comments to editor@eb.com or help@eb.com. [Gleason Sackman (sackman@plains.nodak.edu), net-hap, 7/5/94.] (Britannica and World Book are also producing CD ROM versions, chiefly for purchasers of printed sets. Neither company wants to undercut its extensive sales force. Britannica's CD ROM sells for $1,595, World Book's for $395. CD ROM street prices for Encarta (best for kids), Compton's (families), and Grollier (adults) are $89-99, from $250 list. Sometimes these discs are bundled free with CD ROM drives, or are available in remaindered OEM versions for $35-$45. Apple is shipping Compton's and three other CD ROM choices with its double-speed Multimedia CD Kit, now just over $400. Toshiba and NEC drives are also good, and are offered in bundles by Tiger, EduCorp, and others. MacUser was disappointed by NEC's triple-speed design, but perhaps the caching has improved. Soon everyone will be buying quadruple- speed drives, but no available software really exploits the higher transfer rate.)

AT&T is shutting down its EO portable communicator subsidiary, as only 10K units have been sold since 4/93. [Atlanta Journal- Constitution, 7/28/94, D2. EDUPAGE.]

Thinking Machines is looking for a buyer, having neared bankruptcy due to military spending cuts. [NYT, 7/28/94, C1. EDUPAGE.] Cray has had similar problems, due partly to IBM's entry into the commercial HPC market. [WSJ, 7/29/94 B3. EDUPAGE.]

Franz Inc. (Berkeley) is acquiring the technology assets of Lucid, Inc. (Menlo Park). Franz makes Allegro CLOS/CLIM development tools and databases for Unix and MS Windows; Lucid sells Lucid Common Lisp, Lucid C, Lucid C++, and the Energize C/C++ development environment for Unix workstations. Fritz Kunze is president of Franz Inc.; Dr. Richard Gabriel is/was founder and chairman of Lucid. For more details, contact Hanoch Eiron, (510) 548-3600, or Patrick Corman, (415) 326-9648. [Press release. Bill Wilkinson (wmw@netcom.com), 7/28/94.] (Although portrayed as a merger to better serve customers, I get the impression that Lucid has disbanded and only their software remains intact. I have no word yet on whether Franz will be hiring Lucid staff. Let me know if your own organization wants to hire some Lisp-literate professionals.)

Computer Associates recently acquired ASK, and has refused to continue benefits to unmarried domestic partners (of any sexual orientation). About 100 employees have resigned, mostly from ASK's Ingres subsidiary. [NYT, 7/1/94, C3. EDUPAGE.]

NRL's HCI Lab has closed due to budget cuts, expected to be permanent. NRL is closing 41 positions in DC, 19 in Orlando, and 49 at Stennis AFB. DoD is trying to open slots for Reduction in Force (RIF) casualties by voluntary early retirement (VERA) and separation pay incentive (SPI) offers of up to $25K maximum, but finding equivalent positions for scientists is difficult (especially when the government is not hiring above GS 12 level). Anyone accepting retirement incentives is ineligible for government employment for five years. [NRL Labstracts, 7/4/94. Helen Gigley (gigley@itd.nrl.navy.mil).]

Internet traffic nearly ground to a halt on 7/19/94 as people downloaded pictures of the comet hitting Jupiter. [Information Week, 8/1/94, p. 8. EDUPAGE.]

MIT and CERN are forming an alliance with US and European companies to develop international WWW standards. [WSJ, 7/8/94, B3. EDUPAGE.]

Stanford is selling BARRNet to BBN (Cambridge, MA), to be merged with NEARNET. BBN is better able to provide commercial- quality service upgrades and consulting/training support. BARRNet serves the CommerceNet project and many companies in Silicon Valley and San Francisco. [Rebecca Wetzel (rwetzel@nic.near.net), com-priv, 6/22/94. net-hap.] (IBM has just joined CommerceNet. [SJM, 8/2/94, D2.])

NMTC will be a 9/94 workshop on entrepreneurial uses of "new media" technologies: desktop publishing, video editing, multimedia presentations, interactive media, BBS services, etc. The focus is on actually using this stuff to make money. For details, send an "NMTC '94" subject line and your name in the message body to ilabs@eandc.win.net. [Evan C. Williams (ilabs@eandc.win.net), VPIEJ-L, 7/28/94.]

38% of all publicly traded companies with sales above $400M have some form of Internet presence. The figure is 46% for the 490 companies above $1.5B. [InterNet Info (top_2000 @internetinfo.com). Mike Walsh (p00426@psilink.com), net-hap, 7/31/94.] (The companies not yet on the net form an immense market for telecommunications services. Those just barely on the net may be even easier to work for.)

The USPTO has suspended action on all applications for trademarks using the word Internet. Banks registered the term (or Inter-Net) for their ATM networks in 1975 and 1990, blocking applications from others. [Jayne Levin (helen@access.digex.net), The Internet Letter, 7/5/94. net-hap.]

The "artificial life" community has a new Usenet newsgroup, comp.ai.alife. (They'd rather be a superset of AI or a parallel domain, but there was no better fit in the newsgroup hierarchy.) A FAQ is being developed. [Peter M. Weiss, 8/1/94.]

Cellular automata (CA) in CA machines (CAMs) can be evolved rapidly using genetic algorithms. Toffoli's group at MIT has a CAM8 machine that can update 200M cells/second, with prospects of 10^22 by the end of the decade. (However, the MIT group is being terminated -- against Minsky's objections.) Hugo de Garis at ATR is working (with NTT) toward brain models with thousands of neural modules in two years, then millions. 2D versions with 11,000 rules have worked well so far. [degaris@hip.atr.co.jp, sci.nanotech, 6/17/94.]

Carver Mead's laboratory has announced reliable analog on-chip learning "that will make possible adaptive mechanisms and learning at all levels of processing, as occurs in biological systems." The NSF-sponsored 1st Annual Telluride Workshop on Neuromorphic Engineering studied this and other steps toward artificial brains. Low-power analog VLSI chips already exist for low-level visual and auditory processing. Sensorimotor integration is being studied by Dana Ballard and Richard Andersen, and Rodney Douglas and Misha Mahowald are working on cortical chips. Workshop results will be made available soon via FTP. [Terry Sejnowski (terry@salk.edu), connectionists, 7/22/94.]

On the other hand, jbower@smaug.bbb.caltech.edu notes that few connectionists attend neuroscience meetings. Connectionists have little understanding of, or interest in, neurobiology -- and we are still far from modeling the brain of a bee. For those who want to know more, Dave Beeman is organizing a new discussion list for computational neurobiology. Contact comp-neuro @smaug.bbb.caltech.edu to sign up. [connectionists, 7/28/94.]

An ARL directory lists 50 electronic journals on the Internet, half of them refereed. (In 1991, the numbers were just 27 and 7.) University Libraries' "Report of the Scholarly Communications Task Force" on electronic librarianship is available on http://scholar.lib.vt.edu/reports/SCTF-1994.html, or in PostScript and Acrobat formats from /pub/SCP/reports on scholar.lib.vt.edu. [James Powell (jpowell@vtvm1.cc.vt.edu), VPIEJ-L, 7/25/94.]

Stevan Harnad has been suggesting that learned societies archive and index their members' papers. (Pointers to FTPable papers are also needed, but the academic community moves around quite a bit.) The Physics preprint/e-print archives at http://xxx.lanl.gov/ have over 20K users of 30K articles, with over 35K transactions per day -- I'm not sure what constitutes a transaction -- yet the system is unfunded and unstaffed. Submissions are processed, archived, and indexed automatically, and subscribers are sent digests of abstracts. These primitive systems "have entirely supplanted recognized journals as the primary disseminators of research information in certain fields." Send a "help" or "get blurb" subject line to hep-th@xxx.lanl.gov for more information. [Paul Ginsparg (ginsparg@qfwfq.lanl.gov). serialst and VPIEJ-L, 7/5/94.]

On the other hand, Peter Graham points out that preservation of important literature is what libraries do really well. Other institutions have less experience in long-term archiving subject to short-term budgets and technology changes. [psgraham@gandalf.rutgers.edu, serialst, 7/7/94.]

Are the papers archived by university libraries actually used? "The average article in Science Citation Index is cited by no one and read by not many more." [Stevan Harnad (harnad@princeton.edu), serialst, 7/19/94.]

"With technical advance, one electronic copy of a journal could satisfy the world, and delay would be minimal or nil. So far, the way of paying for such a development has not emerged. Indeed, plenty of people are not sure it needs to be paid for. They believe 'the age of the free lunch' has really arrived." -- Bernard Naylor (b.naylor@soton.ac.uk), LIBER, 7/7/94. [Stevan Harnad, serialst, 7/19/94.]

Scholars are seldom aware of the costs for the publications they use. Andrew Odlyzko notes that the average researcher in mathematics publishes 2-3 papers per year. If $50K/year of salary and benefits is the research component, the cost to students, university donors, and US taxpayers is $20K/paper. A typical math journal accepts half of submissions, and editors and referees appear to donate about 1-2 weeks' time ($4K) per accepted paper. Two reviewing journals (Math. Rev. and Zbl.) each use another $500/paper in unpaid reviewer time. (Paid reviewers could manage it for a much lower salary cost, but subscription prices would be higher.) Publishing costs for a 50KB article vary from $900 to $8,700/paper for different journals, with a median of about $4K/paper -- plus $100/paper for each review journal. (An editorial assistant handling all journal correspondence costs about $100-400 per published paper. Typesetting of mathematical text costs $10-20/page in the US, or $200-400/paper If the author were to do this work separate from original composition, the salary cost might be $1K-3K.) Ignoring the $20K research cost and $5K editing and review costs, a typical scholarly article still costs over $4K to publish. Amer. J. Math. has a paid circulation of 1458 (including libraries), and a typical scholar may skim only a couple of articles. If 20 scholars read each paper in detail, the cost is $200/reading. Even if 200 scholars skim it, the cost is $20 each. "This high cost is likely to doom any pay-per-view efforts in scholarly publications," as scholars object even to copyright fees of even $5-$10. Most of the publishing cost is for the first copy, with additional copies of a whole journal -- Physical Review Letters, in this case -- printed and delivered for about $140/year. This is similar to the cost of photocopying, stapling, and mailing. Electronic delivery eliminates only this small expense, perhaps 15-30% of the publishing cost. However, electronic publishing in the broad sense can trim costs throughout the process. Email reduces correspondence cost, and editing is less expensive when authors provide the typesetting and basic quality control. "Most of the high cost of traditional publishing is caused by the need for communication and cooperation among the many experts involved in the process. With modern technology, doing something is becoming easier than explaining to somebody else what to do." If standards are lowered just a bit, production costs can be kept under $1K/paper -- probably under $500. Uniformity of appearance and style might suffer, but uniformity of papers within one journal volume is of little importance to researchers. Even reference style will be less important when citations are hyperlinks to other documents. Pay-per-view will still be impractical, but site licenses can cover the $500/article production costs. Even lower subscription costs are possible with all-volunteer labor. Quality of peer review is a separate issue from paper vs. electronic publishing. Peers are already handling the review process and are contributing as much work as the publishers. Editing and electronic distribution are very little extra work. [amo@research.att.com, serialst, 7/6/94.]

Lorrin Garson (lrg96@acs.org) of ACS notes that chemical literature is complex, with tables, display math, chemical structures, line art, half-tones, color images, over 500 special characters, and three levels each of subscripts and superscripts. ACS creates journals as an SGML-like database (80-85% of the total cost, for editing, copy-editing, proof-reading, etc.) which is then formatted into print products. Costs for scholarly e-journals must be comparable to those for print journals. ACS has been experimenting with electronic delivery since 1980, including 20K pages per year of supplemental material made available on acsinfo@acs.org. Starting 6/19/94, ACS/CAS made page images of all its chemistry journals available via FTP, FAX, and modem. Journal graphics are being set up as callable objects linked to text, and CD ROMs coming out in 7/94 will have full search and half-tone/gray scale/color printing capabilities. Although ACS is non-profit, its publications arm does make money. Eliminating print publication would have little effect on costs. In fact, costs may increase as the society begins archiving esoteric data collections and the software needed to view them. [harnad@princeton.edu, serialst, 7/5/94.]

The physics community has been publishing equations, graphics, etc., over the networks for nearly a decade. Astrophysicists are even submitting .mpeg animations. Scholarly readers don't particularly want page images -- "photographs of a journal," however presented. They want the information itself. Author-prepared electronic texts often have fewer errors and better graphics than those retypeset by professional publishers. "Those organizations for whom publishing electronic journals will prove more expensive than printing do not have a very bright future." [Paul Ginsparg (ginsparg@qfwfq.lanl.gov), serialst, 7/5/94.]

Stevan Harnad says that authors now provide most of the editing, formatting, and art work, and that their institutions could do much of the copy editing. Adding electronic distribution to a print publication will always cost more, but an ab initio electronic journal can be very cheap. Harnad's PSYCOLOQUY e-journal has a readership of 40K. Costs of production, even with refereeing and quality control, are about $.25/reader/year. He believes that 75% of the costs of traditional journal publication can be saved if scholarly societies take over from commercial publishers. [serialst, 7/5/94.]

(Let each scientist be responsible for his or her own publishing, without mandatory peer review, and publishing costs drop to near zero. Authors, institutions, or societies wanting the imprimatur of peer review can arrange for it themselves. Bibliographic and review publications would become more important, and tracking of revisions would be a problem -- but we could work that out. The mathematics community is not ready for unrefereed (or vanity) publishing, but CS might be. Better one repository for an author's papers than nearly identical versions in seven workshop and conference proceedings, journals, and reprint books. A principal difficulty is that many authors write poorly and need independent copy editing or even substantive editing. Either their institutions or their professional societies should make domain-cognizant editors available, and should perhaps insist on their use.)

David Throop has put together a WWW page on men's issues: male choice (in the matter of abortion), divorce, custody, child support, false abuse/rape allegations, husband battering, and men's movement history, organizations, books, and speeches.

Kumar Vadaparty and his Case Western students have created software for experimenting with sort algorithms and tree structures (binary, red-black, AVL, splay, 2-3, and 2-3+). Also heaps, stacks, lists, graph search, Huffman coding, and tracking of order statistics. Students can rotate a node in a binary search tree, manipulate red-black and AVL trees, and insert data into other animated data structures. Lesson material covers insertion, deletion, and other operations, plus canonical cases, dynamically generated examples, and animations (continuous or step by step). Windows 3.1 format; one floppy. These data structure animations cover two years of course material.

Mark Kantrowitz created the CMU AI Repository in 1993, based on his earlier Lisp Utilities Repository (1990) and his FAQs for the AI, Lisp, Scheme, and Prolog newsgroups. The AI Repository now has more than 1GB of compressed material, including agent architectures and testbeds, artificial life programs, annealing, blackboards, book code, cellular automata, classical AI programs, constraint programming, DAI, data mining, educational tools, expert systems, fuzzy logic, games, genetic algorithms, ICOT software, knowledge representation, machine learning, music, neural networks, NLP, planning, reasoning, robotics, search, speech, vision, and languages such as Common Lisp, Scheme, Prolog, and Smalltalk. The index may be searched with a "keys " (or "help") message to "ai+query"@cs.cmu.edu. (A Mosaic-based search interface is planned.) Files may be FTP'd from /user/ai on ftp.cs.cmu.edu (128.2.206.173), or accessed as http://www.cs.cmu.edu:8001 /Web/Groups/AI/html/repository.html. Be sure to read 0.doc and readme.txt.
