  • ARDG Bans the Press

    – by

    Comments

    Several groups, including the EFF, Consumers Union, DigitalConsumer, and PublicKnowledge, have sent a letter objecting to the Analog Reconversion Discussion Group (ARDG), objecting to ARDG’s policy of refusing journalists access to its “open” meetings. Despite its confusing name, ARDG is an important process, reflecting the efforts of some to promote, and perhaps eventually to mandate,…

  • We're Back

    Comments

    We’re back on the air after roughly thirty-six hours of downtime. Apparently the server that brings you Freedom to Tinker (along with many unrelated sites hosted by the same web hosting provider) has had its hard drives impounded by the authorities as part of a cyberterrorism investigation. The last week or so of backup tapes…

  • DRM, and the First Rule of Security Analysis

    – by

    Comments

    When I teach Information Security, the first lecture is dedicated to the basics of security analysis. And the first rule of security analysis is this: understand your threat model. Experience teaches that if you don’t have a clear threat model – a clear idea of what you are trying to prevent and what technical capabilities…

  • DRM in Cell Phones?

    Comments

    Elisa Batista at Wired News reports on the Cellular Telecommunications and Internet Association (CTIA) trade show. Rep. Billy Tauzin gave his perspective in a speech: But Tauzin did offer [CTIA CEO Tom] Wheeler some advice in order to avoid more regulation: Have the industry clean up its act. If it doesn’t want to be hit…

  • DRM and the Regulatory Ratchet

    – by

    Comments

    Regular readers know that one of my running themes is the harm caused when policy makers don’t engage with technical realities. One of the most striking examples of this has to do with DRM (or copy-restriction) technologies.

    Comments

    Declan McCullagh reports on yesterday’s House Government Reform Committee hearings on porn and peer-to-peer systems. (I’m sure there is some porn on these systems, as there is in every place where large groups of people gather.) There’s plenty to chew on in the story; Frank Field says it “sounds like a nasty meeting.” But I…

    Julian Bigelow, who was chief engineer on the IAS computer (the architectural forerunner of today’s machines) died about three weeks ago at the age of 89. Today I learned where he had lived. For the last seven years I sat at the breakfast table each morning and looked out at the red house behind mine.…

  • Grimmelmann on the Berkeley DRM Conference

    – by

    Comments

    James Grimmelmann at LawMeme offers a typically insightful and entertaining summary of the recent Berkeley DRM Conference. Here’s my favorite part: And thus, the sixty-four dollar question: Is any of this [DRM technology] really going to work? The question tends to come up about once per panel; most of the panelists do their best to…
