Need some Advice
by v20177＠vax1.cc.uakron.edu 03 May '93

Hello All My question is what is the diff. between a Software Eng. & Computer Sci. degree. Some of my profs say that they don't know of any schools offer a BS in Software Eng. If that is the case then why do people use that term? Or is it a Masters degree or something like that? I also would like to thank Eric Hughes for replying to my early question on Q&A a dos database problem. His basic steps solved the problem in less 30 min. By the way the algorithm used very lame. abs(ascii character - 255) I would like a little more info on the debugger method. Has anyone the address to MircoSystems Management magazine, I need the April 93 issue, but unable to find it local. Thanks in advance.

Interesting mail (fwd)
by Al Billings 03 May '93

03 May '93

I received this on the Leri list and thought a little amusement might be appreciated here given the current conversations. ---------- Forwarded message ---------- Date: Sat, 01 May 1993 20:57:34 From: David L Racette <dlr(a)medical.win.net> To: Leri <Leri(a)pyramid.com> Subject: Interesting mail Opening Statement to the House Subcommittee on Telecommunications and Finance, Washington DC, April 29, 1993 Hello everyone and thanks for inviting me here. My name is Bruce Sterling and I'm a science fiction writer and sometime science journalist. Since writing my nonfiction book HACKER CRACKDOWN: LAW AND DISORDER ON THE ELECTRONIC FRONTIER, I have returned to writing science fiction. And I've returned to that with some relief, frankly, since the world of science fiction is in most ways rather less strange and less bizarre than the contemporary world of telecommunications policy. I hope therefore that you will forgive me if I testify today as a science fiction writer. It's one of the perks of my profesion to write about the future, or attempt to, and I thought you might like to meet someone from the telecommunications future that you are so busy creating. With your kind indulgence for my novelist's whimsy then, the rest of my brief presentation today will be given by a Mr. Bob Smith, with is an NREN network administrator from the year 2015. I present Mr. Smith. "Thank you, Mr. Sterling. It's a remarkable privilege to talk to the legislators who historically created my working environment. As a laborer in the fields of 21st Century cyberspace I of course would have no job without NREN and my wife and small son and I are all properly grateful for your foresight in establishing the Information Superhighway. "Your actions in this regard have affected American society every bit as strongly as did the telegraph, the railroads, the telephone, the highway system, and television. In fact, it's impossible for me to imagine contemporary life in 2015 without the Global Net; living without the Net would be like trying to live without electricity. "However, it's a truism in technological development that no silver lining comes without its cloud. Today I'd like to mention two or three trifling problems that have come up that were not entirely obvious from the perspective of the early 1990s. "First of all, this 'Research and Education' aspect. Since communications *is* power in an Information Society, giving fantastically advanced communications to the Research and Education communities did in fact empower those communities quite drastically by comparison with interest-groups lacking that advantage. Today, one of the most feared political organizations in the world is the multi-national anarchist libertarian group called the Students for an Utterly Free Society. "Of course, there have always been campus radicals, but thanks to their relative lack of financial clout, and lack of even a steady home address, these young fanatics once found it very difficult to organize politically. Therefore, they were easy for the powers-that-be to ignore, except during occasional spasms of violent campus unrest. "Thanks to NREN, however, spasms of student unrest can now spread like lightning across entire continents. Advanced AI translation programs installed on the Net only made matters worse, since in 2015 the global leaders of the student movements are not only extremely radical, but French. "Attempts by campus authorities to control this unrest have failed miserably. In 2015, NREN sites are always the first buildings occupied during a campus strike. Campus chancellors and faculty are themselves so utterly dependent on NREN that they become quite helpless off-line. "A second major problem has been the growth of unlicenced encryption, which has proved quite unstoppable. Today some seventy-five percent of NREN archives are material that no one in authority can read. Countries that attempted to control and monitor network traffic have lost market share and service revenue as data processing simply moves offshore. "The United States has profited by this phenomenon to a great extent as people worldwide have flocked to the relative liberty of our networks. Unfortunately many of these electronic virtual immigrants are not simply dissidents looking for free expression but in fact are organized criminals. "Take for instance a recent FBI raid on an enormous archive of encrypted Iranian files, illicitly stored in an obscure NREN node in North Dakota. Luckily the FBI was able to decrypt these files thanks to an inside informant. Deciphering these archives revealed the following contraband: "Eighty percent graphic image files of attractive young women without veils on, or, in fact, much clothing of any kind. "Fifteen percent digitally stored pirated copies of Western pop music and Western videos, still illegal to possess in Teheran. "And, five percent text files in the Farsi language describing how to guild, deliver and park truck-bombs in major urban areas. "I can't conclude my brief remarks today without a mention of a particularly odd development having to do with *wireless* computer telecommunications. Since it is now possible to transact business entirely in cyberspace, including financial transactions, many information entrepreneurs in 2015 have simply given up any physical home. Basically, they have become stateless people, 21st Century gypsies. "A recent tragic example of this occurred in the small town of North Zulch, Texas. There some rural law enforcement officers apprehended a scruffy vagabond on a motorcycle in a high-speed chase. Unfortunately he was killed. A search of his backpack revealed a device the size of a cigarette pack. In searching the dead man's effects, the police officers, who were not computer literate, accidentally broke the device. This tiny device was actually a privately owned computer bulletin board system with some 15,000 registered users. "Many of the users were wealthy celebrities, and the apparent outlaw biker was actually an extremely popular and nationally known system operator. These 15,000 users were enraged by what they considered the wanton destruction of their electronic community. They pooled their resources and took a terrible vengeance on the small town of North Zulch, which, by contrast, had only 2,000 residents, none of them wealthy or technologically sophisticated. Through a combination of harassing lawsuits and sharp real-estate deals, the vengeful board users bankrupted the town. Eventually the entire township was bulldozed flat and purchased for parkland by the Nature Conservancy. "Thanks in part to the advances that you yourselves set in motion, violent conflicts between virtual and actual communities have become a permanent feature of the cultural landscape in 2015." Thank you for your patience in entertaining my speculations. I'll be happy to take any questions -- though only in my real-life persona. Thank you very much.

government free reign on RSA -- from whence?
by ld231782＠longs.lance.colostate.edu 03 May '93

03 May '93

This is driving me crazy. I have asked many people that refer to the U.S. government's free reign on the use of patents in general and RSA technology in particular. There are a lot of very respectable and reputable specialists on this list and I hope they can answer my question. What *specifically* gives the government the *right* to use patents developed `with public money' without licensing, or the RSA patent in particular (if the two are not the same)? Court precedents? A specific law? `congressional hearings'? A condition of agreement to receive NSF funds? >what< ? This little tidbit of information has gotten tossed around so frequently and haphazardly (a bit like an Urban Legend) and it really deserves some sharp scrutiny, at least a bit more than I have ever seen, I suspect it might have some interesting implications to consider.

Re: Voice Privacy
by Sy Verpunc 03 May '93

03 May '93

From: Jason Asbahr <Asbahr(a)uh.edu> I don't remember hearing this exact use of privacy-enhanced voice communication discussed on the list before, but I might not have been paying attention. :-) I started asking about this recently and discovered that a lot of people are interested in it and some of them are even doing something about it. The most promising group is an Internet Engineering Task Force working on a project called 'nevot' (network voice terminal) - I'll include the readme after this post. It's only drawback is that it doesn't handle completely-software low baud rates that'll work over the internet *on top of* v32bis modems running slip or ppp. I'm working with some folks to hack up a really low bandwidth scheme and when our experiments are successful (if...) we'll feed them back to these folks so that everyone can use it. If anyone here is working on low bandwidth digital voice, there's a mailing list on netphone{-request}(a)moink.nmsu.edu - its a low-volume list and really only for reporting what people are working on; chatty discussions would probably be better on comp.speech or sci.crypt. Remember that before we get crypto voice, we need non-crypto voice, so there's no real reason to discuss the basics in a crypto group. What do you think about encrypting voice communication in a non-real-time sense? Say I record a message (8-bit CODEC) on my NeXT or on a friend's PC Soundblaster and then encrypt/scramble the file in such a way that the resultant file is still audible. I can then leave that message on the recipient's answering machine or voice mail box for him to later record and decrypt on his computer. This method would make private voice communication more accessable, as it doesn't require real-time levels of performance. This is baically what the multi-media extentions to email are about - check up on MIME if you don't know about it. Email mechanisms are fine - the concept of a 'software answering machine' is seductive, but we don't need anything special when you can say 'mail -voice fred' and pick up a mike and talk into it... Graham. --------------- See also gaia.cs.umass.edu:~ftp/pub/nevot/* NEVOT - A network voice terminal (BETA RELEASE 1.3 03/25/93) (c) Henning Schulzrinne ============================================================= NOTE: The .nevotinit files from versions prior to 1.3 are incompatible with the current command language and should be deleted. DESCRIPTION: The network voice terminal (NEVOT) allows audio-capable workstations to participate in audio conferences across local and wide area networks. Features: - real-time protocols: - NVP (network voice protocol), as used by 'vat' (LBL) and VT (isi) - 'vat' native packet format and session protocol - RTP draft - versions for: - Sun SPARCstation (SunOS 4.1.x and Solaris 5.x) - SGI Indigo (4D Series) and - Personal DECstations [as soon as we can get the DEC audio library to work] - GUIs: - XView - Tk [in progress] - curses - dumb terminal - fully controllable by Tcl-based command language - can serve as gateway for protocol and encoding translation - network transport protocols: - TCP - unicast/multicast UDP - ST-II [currently inoperative] - several independent concurrent conferences, each with different encoding and compression - DES-based voice encryption (U.S. only) - audio encodings: - 64 kb/s (mu-law PCM) - 32 kb/s G.721 ADPCM (Sun only) - 32 kb/s Intel DVI - 24 kb/s G.723 APDCM (Sun only) - 13 kb/s GSM - 4.8 kb/s LPC codec - each site can use different audio encodings - playback and recording of AIFC and .snd audio files - extensive statistics and tracing facilities - arbitrary voice packet length, which may differ for each site - lost packet and silence substitution - setable audio buffer occupancy - configurable adjustment mechanisms for playout delay, VU meter, silence detector and automatic gain control - redefinable session identifier string with variable substitution DOCUMENTATION: A compressed PostScript file describing Nevot is available for anonymous ftp from gaia.cs.umass.edu, as file ~ftp/pub/nevot.ps.Z. INSTALLATION: The sources are available by anonymous ftp from gaia.cs.umass.edu, as file ~ftp/pub/nevot/nevot.tar.Z (compressed tar file). The platform- specific external libraries are contained in the directory pub/nevot/lib.$ARCH. These typically change rarely. ARCH can be either dec, sgi, or sun4. Precompiled binaries are available as well: nevot/bin.$ARCH/nevot.tar.Z For the precompiled binaries, you also need to retrieve the initialization file ~ftp/pub/nevot/nevotinit and rename it to .nevotinit in the directory from which you plan to start Nevot. Unpack the compressed tar files, then execute the shell script compile You may have to adjust parameters within the shell script to your local needs, e.g., the compiler name. You also have to install the tcl library (version 6.7 or later), either the binary version as mentioned above, or from sources to be found in sprite.berkeley.edu:tcl. In order to use the UDP multicast and/or ST-II facilities, you have to install the appropriate kernel modifications. Due to export restrictions, the DES encryption code is available only by e-mail from the author. If you do have the DES code, change the value of the symbol DES in the Makefiles to 1. To enable on-line help for the OpenWindows version, the environment variable HELPPATH should be set to include the source directory where the .info files are located (here, assumed to be /usr/local/nevot/xview): setenv HELPPATH ${HELPPATH}:/usr/local/nevot/xview OPERATION WITH SD: ------------------ sd is a session directory written by Van Jacobson, LBL, available for anonymous ftp at ftp.ee.lbl.gov. The nevot/sd directory contains a replacement for the sd start_audio procedure, which you can insert into your ~/.sd.tcl startup file. Make sure that the directory containing the Nevot binary is in your path. Use at your own risk (i.e., don't blame VJ if it doesn't work...). DIFFICULTIES: ------------- If you experience difficulties, check the problems.tex file in the doc directory. BUG REPORTS: This is a beta release. Please send all bug reports and suggestions to the author at hgschulz(a)cs.umass.edu. New releases will be announced through the rem-conf mailing list (to join the list, send a request to rem-conf-request(a)es.net) I would appreciate if you could let me know how you are using the software.

ANON: hop.mail replacements random number generation in perl
by Stop the Big Brother CHip 03 May '93

03 May '93

#<application/x-pgp -----BEGIN PGP SIGNED MESSAGE----- Hi All, I am currently upgrading Hal's Remailer to work with SVR4(mail lock files as opposed to flock) and encryption of the message body. I am also looking at the implementation of the following design goals: * Definition and implementation of a cryptographic MIX protocol compatible with the present day remailers(or with minor script changes). Another area I am working at present on is a replacement for the present anon.mail and hop.mail in perl. Design goals for that companion script are: * Automatic generation of random hop routes for anonymous encrypted remailer return addressing blocks(function 2 from hop.mail) * Hop.mail mailing of files(Function 1) with auto route selection and generation. Other desirable properties of a automatic remailer route generation script would be: * An encrypted remailer would always be selected as the beginpoint and endpoint in a remailer random route selection. * Non-Encrypted but anonymous remailers can only be used as the linkage remailer between 2 encrypted remailer nodes. * The next remailer number generated must be different than the previous remailer number generated. * route generation scripts should generate n number of nested remailer blocks where n is greater 4 and less than 30. * remailer numbers may be used multiple times in the same route generation subject to the conditions listed above. * a random seed needs to be generated to prime the generator. * A MUCH better function than perl's rand is needed. For the curious I am implementing this on a Stock SVR4 system with MH 6.8(MIME). All scripts are being implemented in PERL (PL36). I am interested in critique, additional desirable design goals etc. - -- Parts of this .sig borrowed with permission from T.C.May.

This method would make private voice communication more accessable, as it doesn't require real-time levels of performance. Perhaps one of the PGP gurus could advise on how this sort of private communications could be accomplished. If PGP is used as the encryption tool, then making the encrypted file audible is not unlike making an encrypted file "readable" by turning it into mailable ASCII. It is probably important to consider that recording an "audio armored" encrypted voice message to an answering machine or voice mail box will introduce various kinds of distortion. Is anyone experienced with error-correction methods for audio transmissions? Jason Asbahr 116 E.
