I’m going to talk about some of the people who I think were important in setting the shape of things to come. My criteria isn’t really who is most worthy but rather, who did really important things, is interesting, and some early figures have a local Boston connection as you will see.

VP and Dean of Engineering at MIT from 1932
One of his students was Claude Shannon, who went on to write “The Mathematical Theory of Communication” an important foundational work in information theory
Headed National Research Defense Council 1938 (later Office of Scientific Research and Development). As such he initiated the Manhatten Project which developed the first atomic bombs.
1938 appointed vice-chair to the National Advisory Committee for Aeronautics which he soon ended up chairing. This was the forerunner of NASA.
Declined to fund Norburt Weiner’s digital computer project, but the Army did. This became ENIAC, one of the first all-purpose general programmable digital computers.
Later instrumental in setting up the National Science Foundation.

As We May Think:

“The camera hound of the future wears on his forehead a lump a little larger than a walnut. It takes pictures 3 millimeters square, later to be projected or enlarged, which after all involves only a factor of 10 beyond present practice…

The Encyclopoedia Britannica could be reduced to the volume of a matchbox. A library of a million volumes could be compressed into one end of a desk. If the human race has produced since the invention of movable type a total record, in the form of magazines, newspapers, books, tracts, advertising blurbs, correspondence, having a volume corresponding to a billion books, the whole affair, assembled and compressed, could be lugged off in a moving van. Mere compression, of course, is not enough; one needs not only to make and store a record but also to be able to consult it, and this aspect of the matter comes later. Even the modern great library is not generally consulted; it is nibbled by a few…

All this is conventional, except for the projection forward of present-day mechanisms and gadgetry. It affords an immediate step, however, to associative indexing, the basic idea of which is a provision whereby any item may be caused at will to select immediately and automatically another. This is the essential feature of the memex. The process of tying two items together is the important thing…

Wholly new forms of encyclopedias will appear, ready-made with a mesh of associative trails running through them, ready to be dropped into the memex and there amplified. The lawyer has at his touch the associated opinions and decisions of his whole experience, and of the experience of friends and authorities. The patent attorney has on call the millions of issued patents, with familiar trails to every point of his client’s interest. The physician, puzzled by its patient’s reactions, strikes the trail established in studying an earlier similar case, and runs rapidly through analogous case histories, with side references to the classics for the pertinent anatomy and histology. The chemist, struggling with the synthesis of an organic compound, has all the chemical literature before him in his laboratory, with trails following the analogies of compounds, and side trails to their physical and chemical behavior…

The historian, with a vast chronological account of a people, parallels it with a skip trail which stops only at the salient items, and can follow at any time contemporary trails which lead him all over civilization at a particular epoch. There is a new profession of trail blazers, those who find delight in the task of establishing useful trails through the enormous mass of the common record. The inheritance from the master becomes, not only his additions to the world’s record, but for his disciples the entire scaffolding by which they were erected…

The impulses which flow in the arm nerves of a typist convey to her fingers the translated information which reaches her eye or ear, in order that the fingers may be caused to strike the proper keys. Might not these currents be intercepted, either in the original form in which information is conveyed to the brain, or in the marvelously metamorphosed form in which they then proceed to the hand?

In the outside world, all forms of intelligence, whether of sound or sight, have been reduced to the form of varying currents in an electric circuit in order that they may be transmitted. Inside the human frame exactly the same sort of process occurs. Must we always transform to mechanical movements in order to proceed from one electrical phenomenon to another? It is a suggestive thought, but it hardly warrants prediction without losing touch with reality and immediateness…”

“In the foregoing, I must have exercised several network features. I engaged in information retrieval through some kind of system that looked for programs to meet certain requirements I had in mind. Presumably, this was a system based upon descriptors, or reasonable facsimiles thereof, and not in the near future, upon computer appreciation of natural language. However, it would be pleasant to use some of the capabilities of avant-garde linguistics. In using the borrowed programs, I effected some linkages between my programs and the borrowed ones. Hopefully, I did this without much effort–hopefully, the linkages were set up–or the basis for making them was set up–when the programs were brought into the part of the stytem [sic.] that I was using. I did not borrow any data, but that was only because I was working on experimental data of my own. If I had been trying to test some kind of a theory, I would have wanted to borrow data as well as programs.

When the computer operated the programs for me, I suppose that the activity took place in the computer at SDC, which is where we have been assuming I was. However, I would just as soon leave that on the level of inference. With a sophisticated network-control system, I would not decide whether to send the data and have them worked on by programs somewhere else, or bring in programs and have them work on my data. I have no great objection to making that decision, for a while at any rate, but, in principle, it seems better for the computer, or the network, somehow, to do that. At the end of my work, I filed some things away, and tried to do it in such a way that they would be useful to others. That called into play, presumably, some kind of a convention-monitoring system that, in its early stages, must almost surely involve a human criterian as well as maching [sic.] processing.”

“The earliest ideas for a computer network intended to allow general communications among computer users were formulated by computer scientist J. C. R. Licklider of Bolt, Beranek and Newman (BBN), in April 1963, in memoranda discussing his concept for an “Intergalactic Computer Network”. Those ideas contained almost everything that composes the contemporary Internet. In October 1963, Licklider was appointed head of the Behavioral Sciences and Command and Control programs at the Defense Department’s Advanced Research Projects Agency — ARPA (the initial ARPANET acronym). He then convinced Ivan Sutherland and Bob Taylor that this computer network concept was very important and merited development, although Licklider left ARPA before any contracts were let that worked on this concept.[5]

Ivan Sutherland and Bob Taylor continued their interest in creating such a computer communications network, in part, to allow ARPA-sponsored researchers at various corporate and academic locales to put to use the computers ARPA was providing them, and, in part, to make new software and other computer science results quickly and widely available.[6] In his office, Taylor had three computer terminals, each connected to separate computers, which ARPA was funding: the first, for the System Development Corporation (SDC) Q-32, in Santa Monica; the second, for Project Genie, at the University of California, Berkeley; and the third, for Multics, at MIT. Taylor recalls the circumstance: “For each of these three terminals, I had three different sets of user commands. So, if I was talking online with someone at S.D.C., and I wanted to talk to someone I knew at Berkeley, or M.I.T., about this, I had to get up from the S.D.C. terminal, go over and log into the other terminal and get in touch with them. I said, “Oh Man!”, it’s obvious what to do: If you have these three terminals, there ought to be one terminal that goes anywhere you want to go. That idea is the ARPANET”.[7] Somewhat contemporaneously, several other people had (mostly independently) worked out the aspects of “packet switching”, with the first public demonstration presented by the National Physical Laboratory (NPL), on 5 August 1968, in the United Kingdom.[8]”

“The initial ARPANET consisted of four IMPs:[15]

University of California, Los Angeles (UCLA), where Leonard Kleinrock had established a Network Measurement Center, with an SDS Sigma 7 being the first computer attached to it;
The Stanford Research Institute’s Augmentation Research Center, where Douglas Engelbart had created the ground-breaking NLS system, a very important early hypertext system (with the SDS 940 that ran NLS, named “Genie”, being the first host attached);
University of California, Santa Barbara (UCSB), with the Culler-Fried Interactive Mathematics Center’s IBM 360/75, running OS/MVT being the machine attached;
The University of Utah’s Computer Science Department, where Ivan Sutherland had moved, running a DEC PDP-10 operating on TENEX.

The first message on the ARPANET was sent by UCLA student programmer Charley Kline, at 10:30 pm on 29 October 1969, from Boelter Hall 3420.[16] Kline transmitted from the university’s SDS Sigma 7 Host computer to the Stanford Research Institute’s SDS 940 Host computer. The message text was the word login; the l and the o letters were transmitted, but the system then crashed. Hence, the literal first message over the ARPANET was lo. About an hour later, having recovered from the crash, the SDS Sigma 7 computer effected a full login. The first permanent ARPANET link was established on 21 November 1969, between the IMP at UCLA and the IMP at the Stanford Research Institute. By 5 December 1969, the entire four-node network was established.[17]”

Did Government build the Internet?

Did Government build the Internet?

A DARPA project manager, acoustical psychologist Dr. JCR Licklider of BBN Corporation, or “Lick” as he was called, had an “epiphany” and envisioned an “Intergalactic Network”. Lick’s Intergalactic Network would include email and remote sign-on that would someday bind together the galaxy, Licklider had his epiphany when he saw the first DEC TX-0 computer, originally developed for Project SAGE.

Dr. Licklider went to his managers at DARPA and received about a million dollars in initial funding to create what became the ARPAnet, the lineal forerunner of today’s internet. The ARPAnet was not open to private individuals working in small groups through voluntary cooperation. ARPAnet was open only to the military, large corporations with substantial military contracts, and research universities receiving DARPA funding.

It was government funding which paid for the development of all of the basic internet protocols we use in some form today such as packet switching in the form of NCP, the predecessor to the TCP/IP of today. DARPA started funding research for ARPAnet in 1969. In 1982, the first inter-network gateway was set up, to CSNET. In 1990, government funding for the ARPAnet ended. Government funding continued for a few years under NSFnet, which funded a “backbone” of (for then) high-speed long distance connections for computer data.

Mr. Johnson would be correct in his statements about small voluntary associations of individuals building computer communications systems if he were talking about bulletin board systems, FIDOnet, or USENET. However, those were not the ARPAnet and did not contribute in a significant manner to the eventual structure and topology of the ARPA Internet.

The New York Times erred in publishing this essay, which is based on statements about the history of the Net which are absolutely and provably false.

Comments on ‘Net Neutrality’

I sent the below to some friends when asked to join a letter advocating “Network neutrality”:

I am generally opposed to any federal or state regulation of what internet service providers can do vis a vis routing and BGP, packet prioritization etc. I do think that telcos should continue to function as common carriers, and that all commercial ISP’s should be required to reveal their packet prioritization and bandwidth clamping as part of consumer protection regulation, rather than being allowed to use the “up to 1.5 megabytes per second fast” kind of formulation in advertising.

There is no capital-I “Internet”. And there has not been since the NSF backbone shut down April 30, 1995. There is merely a loose association of networks who have agreed to share traffic over RFC-documented protocols. Each of the networks is entirely autonomous and self-governing.

It is the autonomous, voluntary, and self-governing aspects of the internet which are most important to preserve, not “net neutrality”. Internet freedom means that we allow other people to do things on their network which we personally don’t like (and may not allow on our network).

“We reject: kings, presidents and voting. We believe in: rough consensus and running code”

–Dave Clark, “An Input/Output Architecture for Virtual Memory Computer Systems”, Ph.D. dissertation, Project MAC Technical Report 117, January 1974

Networks belong to the people who own them. There is no reason that I, as a person who owns a network, should have to pay for additional bandwidth charges to say, backhaul traffic for AT&T or Google over my network if they are not clients of mine, or that I should route their packets over my net at all if I don’t want to. Nor should I have to give a non-subscriber equal priority on my network as say, medical imaging facilities for a customer.

“Net neutrality” is a shibboleth; I think we should avoid using the term and talk instead about “common carrier” status for the telcos and large ISP’s and voice carriers.

Riese: A Girl and her Wolf

Riese: A Girl and her Wolf

Riese and Fenrir
Riese and Fenrir

I recently ran across a new web-only action/adventure production called Riese. The eponymous main character, played by Christine Chatelain, is fleeing from a tyrannical regime in the steampunk kingdom of Elysia. I like the Mad Max look of the costumes and the Dr. Horrible like semi-pro abandon with which the series is being edited and shot. The general premise, good kingdom overtaken by evil cult; heir(ess) on the run… is as old as the stories of Theseus and Oedipus. The show has an appealing during/post apocalypse sense which puts one in mind of A Boy and His Dog, Mad Max, especially the third installment, Beyond Thunderdome, V for Vendetta, Children of Men, The Handmaid’s Tale and many others. However it is a nice place from which to explore good versus evil, individual versus society and such tropes. The heroine has at least one supernatural seeming ability: to keep her eyeliner and eyeshadow lipstick and foundation pristine and unsmeared despite being pursued through the woods while wearing goggles and bleeding from a side wound and then engaging in a rather clumsy knife fight with several Mad-Maxian attackers.

I am generally happy with people taking their vision directly to web rather than letting it be ground up and homogenized by the “entertainment” industry.

Whether it be “Star Trek Phase II”, Star Wars Revelations, Dr. Horrible’s Sing-Along Blog, lonelygirl15, or the semi-professional docu-humor of Michael Moore or Morgan Spurlock, such efforts can be good even if writing/acting/scripting/editing are not all that they could be because they are fun and true and come from the heart.

So bon chance to Riese. Here’s hoping it is not too horrible.

Characteristics of internet organizations and corporations

We reject: kings, presidents and voting.
We believe in: rough consensus and running code.

David Clark
Former Chair of the IAB, forerunner of IETF, 1992

Characteristics of internet organizations and corporations include:

  • Very flat organizational structure
  • Lack of respect for traditional models of organization (nation-states,
    for-profit corporations)
  • “Can-do” attitude
  • Social mission
  • Community
  • Respect for internet traditions
  • Computer-mediated communications
  • Innovation
  • Meritocracy

Examples of Internet-related organizations:

  • Sendmail Consortium Administers a widely used internet mail server program called Sendmail. Partnered with for-profit Sendmail Inc., see Sendmail Inc. corporate fact sheet.
  • Open Source Initiative A 501(c)3 tax exempt corp. Certifies open-source software.
  • Internet Engineering Task Force Principle engineering and standards-making body, under the auspices of
  • ISOC, the Internet Society ISOC sponsors the published internet standards, the RFC’s
    (Requests for Comments).
  • ARIN, American Registry for Internet Numbers

    Applying the principles of stewardship, ARIN, a nonprofit corporation, allocates Internet Protocol resources; develops consensus-based policies; and facilitates the advancement of the Internet through information and educational outreach.

    ARIN assigns internet numbers to the US and parts of the rest of the world. Other Regional Internet Registries include AfriNIC,, APNIC,, LACNIC,, and RIPE NCC,

  • Mozilla Foundation
  • We are helping make the Internet a place… where you and your neighbours build the world you want. that generates not only economic value, but also civic and social value. that is optimized for multiple languages and locales. that is trustworthy and has minimal risk for users.

    The Mozilla Foundation is a non-profit organization that sponsors the Mozilla project and devotes its resources to promoting openness, innovation and opportunity on the Internet. We do this by supporting the community of Mozilla contributors and by assisting others who are building technologies that benefit users around the world.

    Sponsors of Firefox, Thunderbird and many other projects.

    Partnered with Mozilla Corporation, a for-profit subsidiary.

  • ICANN, Internet Corporation for Assigned Names and Numbers, a not for profit Corporation which superrvises the Domain Name System under the auspices of US Department of Commerce
  • IANA, the Internet Assigned Numbers Authority,

    The Internet Assigned Numbers Authority (IANA) is responsible for the global coordination of the DNS Root, IP addressing, and other Internet protocol resources.

    IANA is now operated by ICANN.

  • DARPA, the US Defense Advanced Research Projects Agency,

    The Defense Advanced Research Projects Agency (DARPA) is the central research and development organization for the Department of Defense (DoD). It manages and directs selected basic and applied research and development projects for DoD, and pursues research and technology where risk and payoff are both very high and where success may provide dramatic advances for traditional military roles and missions.

    DARPA funded the Arpanet, forerunner of the Internet, and gave rise to much of the Internet’s risk-taking and out-of-the-box-thinking culture. Specializes in technologies leading to “disruptive change”.

The Global Internet is arguably larger than any corporation or nation in history, yet it has a very flat and dispersed implicate order. And it does work, most of the time.
