On my old web site (in the pre-blog days) I had a page with brief reviews of various books and music. Now that my blog is up and (sort of) working I’ve decided to revive that practice. For my first entry I’ve chosen Petra Haden Sings: The Who Sell Out. I found out about this album from a story in the Washington Post, and was intrigued enough to check it out. As it happens I’d never bought or heard the original version of The Who Sell Out, so except for “I Can See for Miles and Miles” I was hearing every song for the first time. And there are some excellent songs on the album, of which my favorite at the moment is “I Can’t Reach You.” ...

In previous posts I discussed the basics of Clayton Christensen’s disruptive innovation theory and considered whether Firefox is a disruptive innovation. In this post I try to describe the ”value network” for Firefox, using Christensen’s definition: “[a firm’s] upstream suppliers; its downstream customers, retailers, and distributors; and its partners and ancillary industry players” (Seeing What’s Next, p. 63). I also discuss how the Firefox value network overlaps (or not) with the value networks of Microsoft and others. ...

In a previous post I discussed Clayton Christensen’s “disruptive innovation” theory (as popularized in The Innovator’s Dilemma and other books) and how it applied to the rise and fall of Netscape. In this post I turn to more recent events, and attempt to answer at least some of the five questions with which I ended previously: Is Firefox more of a sustaining innovation or a disruptive innovation? In what sense is the Mozilla project pursuing (or could pursue) disruptive strategies, whether based on low cost or competing against nonconsumption? ...

I have just submitted a Mozilla CA certificate policy 1.0 release candidate to the Mozilla Foundation and mozilla.org staff for consideration as an official 1.0 policy. This version of the policy is basically the draft 12 version with two changes: I explicitly marked the policy as a release candidate. I made a minor change to the last sentence in clause 7 to clarify the meaning of the sentence. Here is the message I sent to mozilla.org staff recommending adoption of the policy. Note that I tried to distinguish between points on which there has been reasonable consensus (at least among the people who’ve commented on the policy throughout this process) and points on which no real consensus exists (at least in my opinion); I also tried to fairly characterize the nature of any remaining disagreements and indicate the implications for future policy. ...

I’ve just posted a new draft 12 of the proposed Mozilla CA certificate policy, and absent strong objections plan to submit this to the Mozilla Foundation for approval as a 1.0 policy. The two substantive changes in this draft are as follows: To address some of the concerns expressed about CAs issuing “duff” certificates (defined loosely as certificates that are dubious from a security or technical point of view) I’ve expanded clause 4 to add examples of certificate-related problems that might cause us to reject a CA’s application for inclusion or to consider removing an already-included CA certificate. ...

I’ve previously thought of Jamie Zawinski not just as an excellent hacker but also as a marketing talent, creator of the original mozilla.org “brand.” (Imagined conversation: “You know, these open source and free software types are all radical anarchists or Marxist hippies; they’ll really go for a brand image that reminds them of trashing a WTO meeting” “Well, Jamie, you’re the expert. . . .”) Now based on his “groupware bad” rant it turns out that JWZ is also a leading-edge corporate competitive strategist; maybe the people getting Harvard Business School MBAs could take a break and hang out at the DNA Lounge instead. ...

UPDATE 2023-03-27: This page is obsolete, as it refers to a prior version of this blog. However, it may be of historical interest. I recently experienced a strange problem with the Atom feed on my weblog. My weblog server is running on US Eastern time as the basic time zone, but the story dates in the Atom feed should be expressed in UTC/GMT; the atomfeed plugin has code that supposedly should do any necessary conversions. On my local test blog (running under OS X 10.3 using Perl 5.8.1) this worked fine, but on my real blog (running on Red Hat Enterprise Linux 3 using Perl 5.8.0) the dates in the Atom feed were incorrect; they were five hours earlier than what they should be, suggesting that they didn’t get converted to UTC/GMT. After some investigation this turned out to be due to non-portable code in the atomfeed plugin. ...

I happened to stumble upon a blog post by Jennifer Rice on “Love/Hate brand scores". She did a thoroughly unscientific comparison of common brands based on querying Google for “I love Foo” and “I hate Foo” (similar to Googlefight, but taking the idea a bit further). I’ve recomputed her results and included some brands and products of interest to us. Here’s the original Love/Hate brand score table, with all figures recomputed based on new searches (partly so I can understand exactly how she computed her results, and partly to get a consistent baseline for adding Firefox et.al. ); I’ve left the brands in the same order as in Rice’s table for ease of comparison. ...

I’ve posted a new draft 10 of the proposed Mozilla CA certificate policy. The only substantive changes are as follows: I changed the language on disclosure of financial compensation (i.e., of independent evaluators by CAs) to read “publicly disclose” as opposed to “fully and publicly disclose”; in other words, I dropped the word “fully.” I added a section discussing revision of the policy, and noting that such revision would be done only after public discussions (similar to what we’re doing now). ...

In the course of our discussing the proposed Mozilla CA certificate policy, Ian Grigg happened to ask about the existing Mozilla policy on handling security bugs and how we tried to forge a compromise between people advocating full disclosure of security bugs and people who were opposed to that. (Ian was interested in this because he and Adam Shostack have been blogging on the “economics of disclosure.”) I happened to look back at the Google archives of the discussions we had, and found some material that I thought was worth revising, reprinting, and commenting upon, especially for people who are not aware of how the current Mozilla policy came to be. ...
