When I switched to drupal, I lost the “type in my first name” code to stop comment spam that I had written for Movable Type. I used drupal’s systems for spam spotting and comment moderation, but in fact those are not very good yet, so I re-coded the system so that anonymous commenters can comment directly if they answer a simple question on the comment form. The question, in this case the trivial one of entering my first name, is easy to answer and can be handled by the blind (which is not true of captchas.) If spammers should write programs to fill in that field, I can quickly change the question or make it more complex as needed. If spammers start to automate answering trivial questions faster than we can think them up, then perhaps we can consider captchas and other more advanced turing tests.
Note that you won’t see the question if you are a registered user of this site (you can also log in with your idea from most other drupal sites too) so registration is encouraged but not required.
Comment spam is a nasty scourage. I think Movable Type as the most popular software gets the most but all systems that get popular will get hit. In addition I modified drupal to use the rel=nofollow tag on homepage links — it already does it on other links in comments — so spammers gain no search engine credit for their spam. Sorry, that also applies to honest commenters.

I am told an interview I did a few months ago on USENET and elements of its history will air today on the American Public Media show “Marketplace.” The audio can be played from the Marketplace web site in realplayer format. It airs on most NPR stations at times ranging from early afternoon to about 6:30pm.
I did my interview mostly on history, but the story ended up mostly being about Google with just a few quotes from me (with other quotes from friends of mine like Marissa Meyer and Lauren Weinstein, who got to play the privacy advocate though it’s normally my job.)
When I did this interview, I did it by phone but put on a headset mic and recorded my audio locally. Then I uploaded an MP3 of my end to Marketplace. I also did this with an All Things Considered interview in 2003. Worked out pretty well.
If you’re curious about what the original interview (about USENET) sounded like before being turned into quotes for a Google story, you can hear my side (but not the questions, but you don’t need them) by downloading it from this 5 megabyte Speex File. You will need a Speex decoder (it is a free codec meant just for good quality speech, you’re getting 5 minutes of audio per megabyte!) If you can’t do Speex, try the 15MB mp3

I’ve switched the blog from Movable Type to drupal. Drupal is a PHP based, open source blog and community system that will allow me in the future to support all sorts of fancy things, such as discussion forums, polls, multi-user blogging and a lot of other stuff. Drupal is entirely another class of application beyond MT, though I won’t be using all of what it has at first.
For now, you will of course see a different look for the blog. Categories can be expanded from the navigation menu and you can do more things with them. You can also create a userid and password to log in. If you do this, comments appear under your name and they appear immediately without need for me to approve them. You also can configure how the site looks for you and turn on other features. I can even give users a blog in the future if you like, when the permission system improves. If you have a login at many other drupal sites you can use it here, by using the userid username@thedrupalsite. (Or use email@example.com on other drupal sites.)
Let me know if there are any problems.

I've disabled the trackback feature that allows other blogs to tell this blog they have pointed to it. It's being abused by spammers. Unlike comments, which can have a little turing test on them, trackback needs to be automatic to work, so it's a lot harder to protect against spam except through complex blacklists etc.
I'll see people who link to me in my weekly referer logs. I wrote a nice script that keeps track of all referers, and figures out which ones are new, and which ones suddenly brought in a lot of traffic, and I have it generating a summary once a week. I should release it some day...

Dan Gilmor notes that he is concerned about a new program called the “Silicon Valley 100” in which a marketing company identified 100 influentical silicon valley folks with plans to give us stuff in the hope of generating buzz. Dan worries whether people will disclose they got the stuff for free as part of this venture.
I certainly never had any thought of keeping it secret, and having my name in Newsweek certainly wouldn’t make it easy to do so. Slashdot called it an “elitist club” but in fact, all it amounted to for me was getting an E-mail from Auren Hoffman asking if I could be put on the list and if I would mind being sent free stuff with no strings attached.
I actually at first wondered if it was a particularly clever phishing attempt. My brain is trained to be wary at notes from strangers saying, “We’ll send you lots of free suff, just give us your address.” :-) Back at the dawn of the internet, my e-mail address got put in a book called “E-mail addresses of the rich and famous.” I was flattered for about 10 seconds until I saw all the bizarre spam I ended up getting because of it.
But I couldn’t see any reason not to let them send me the stuff. My opinion certainly can’t be bought so easily, and most of the people on the list are well off enough that the same applies.
So while I was planning on disclosing the background — I am naturally skeptical and assume the people I talk to should be as well — I don’t even really have Dan’s reservations about those who don’t go out of their way to disclose this. As he says, the press get most of the stuff they review for free and it’s just assumed. (To the credit of his arguments, this is not true of Consumer Reports, which is indeed very high integrity.)
Will this program get us to talk about products we would not have gone out and bought on our own, or talked about if we did buy them? Quite possibly. I just don’t see it as so sinister, or novel. So, once I figured it wasn’t a phishing scheme, I said I would give it a whorl.
And oh yeah, I’m taking the toilet seat for a second bathroom, because I already have a different brand in my master bathroom, and think in general they’re cool. No idea about the one they’re sending yet. Now whether Hoffman will get people to blog about their hemorrhoid problems is a different question.

I'll be speaking at three conferences in the near future, and can offer discounts to blog readers for two of them.
Coming up October 19, I will be speaking on the future of SIP, and whether IAX2 or Skype might kill it, at the Pulver Voice on the Net conference in Boston.
Nanotech and Privacy
Later that week, I will chair day 2 (Sat, Oct 23) of the Foresight Conference on Advanced Molecular Technology in Washington, DC. Friday is about technology, Saturday is about Applications, Sunday is Policy. On Saturday I will deliver a talk on the merits of privacy which will lead into a debate about privacy and surveillance in the nanotech world.
Blog readers who wish to attend this conference can get a 30% discount by using registration code BRAD30-CP.
Debating David Brin on Privacy
Then, on November 6, I will do a similar debate at Accelerating Change 2004, this time with noted Science Fiction author David Brin (who also wrote "The Transparent Society.) Blog readers can get a $50 discount before Oct 20 by using the code AC2004-BRAD.
After that it's off to the Vintage Computer Festival, and Hackers.
Burning Man Decompression
Plus, before all that, this Sunday I will be at the Burning Man Decompression party, a small taste of Burning Man on the city streets. I will display my latest giant photographs, plus my Star Map and with luck we will have the phone booth in operation, though it won't be as out of place on a city street.
EFF Salon on E-Voting
And finally, though I won't be speaking at it, the EFF has restarted our BayFF series of talks and salons on major issues. The next is Tuesday, October 12, 7pm at the 111 Minna Gallery in San Francisco on the subject of e-voting and the upcoming election. Free, but how much would it hurt you to donate?

I regret to get in anybody's way, but the volume of comment spam I have been getting has been driving me nuts, and Movable Type makes it a royal pain to delete. There is no point in them spamming, I turned off putting links on URLs they include in the spams, but they do it anyway.
Anyway, to stop them, I added a box to the comment form where you have to enter a word I describe. No, I don't put the word in an image -- that popular technique is shutting the blind off from a growing part of the web -- I just describe it in English. Just a warning for those wanting to comment. And hope no spammers decide to automate it (if they do I change the question.)

I have accepted an invitation to join the Board of Directors for the Foresight Institute for Nanotechnology.
Foresight was created by Chris Peterson and Eric Drexler, author of "Engines of Creation" to act as advocate and watchdog in the field of molecular nanotechnology, of which Eric can claim to be the modern father. I've been a senior associate of the institute for some years and spoken at their conference. I will MC the conference coming up next weekend.
While I put most of my focus right now into issues of computer technology, software, civil rights and the internet, if you ask me what the true "next big thing" is, it's in nanotech, so I'm very pleased to be part of Foresight.
I should also note that Foresight is seeking a new executive director to manage the operations of the institute and take a leadership role in the future of nanotechnology. Contact me if this could be the job for you -- but please, plain-text ASCII resumes only, no word processor files.

The weekend of May 14th, I will be attending (and MCing for part of) the Foresight Senior Associates Conference. This conference is always a lot of fun, with many at the edge (and beyond) ideas about nanotech, AI, anti-aging and other related topics. It's run by my friends Chris Peterson and Eric Drexler and their Foresight Institute. You may have read Eric's book "Engines of Creation."
They are offering readers of my blog a $200 discount on attending. To attend, you must be a senior associate, which requires a $250 annual donation, so the discount just about compensates for that. If you're into futurism, this is a fun place to be.
