Random Palo Alto stuff - wheelchair bandit, chickens, Comcast

April 7th, 2008 5:21pm

It’s the time of spring when all the flowering trees bloom. There are a lot of cherry and wisteria trees in our neighborhood, it looks nice and as the petals start falling in a few weeks off later it will look like every home held a wedding recently. Good weather for being out and about. Speaking of which…

The Wachovia Bank (formerly World Savings) branch over at the Stanford Shopping Center was robbed last Thursday. This is already a little unusual, but what caught my attention was that they were robbed by an elderly man in an electric wheelchair. And he got away! He apparently stopped by The Sharper Image and asked for a shopping bag on his way over to the bank.

Hacked by keymachine.de

April 2nd, 2008 6:15pm

I just noticed that my Wordpress installation got hacked by a search engine spam injection attack sometime in the past few weeks. This particular one inserts invisible text with lots of keywords in footer.php. The changes to the file were made using the built-in theme editor, originating from ns.km20725.keymachine.de, which is currently at 84.19.188.144. The spam campaign automatically updates the spam payload every day or so. The links point to a variety of servers that have also been hacked to host the spam content. Here is a sample: http://www.nanosolar.com/feb3/talk.php?28/82138131762.html
I’ve sent an e-mail to Nanosolar, so they’ll probably have that content cleaned up before long. But the automated SEO spam campaign updates the keyword and link payload regularly, so any affected Wordpress sites will be updated to point at the new hosting victims.

Hey, it’s an earthquake

October 30th, 2007 7:19pm



We had a noticeable earthquake a few minutes ago this evening. Nothing too severe, but the hanging lamps were swinging back and forth a few inches, and the house was shaking for 15-20 seconds. Apparently it was magnitude 5.6, somewhere near Alum Rock.

Volvo’s pointlessly paranoid heartbeat sensor

March 25th, 2007 7:10pm


A few days ago, the first time I saw the television ad for the new Volvo S80’s heartbeat sensor alarm, I thought it was a parody. It shows a woman walking up to her car in a dark parking lot, then turning away after the heartbeat detector shows that someone is hiding in her car. I’m sure they test marketed this before including the feature, but I totally don’t get it.

Here’s what the Volvo site says about the feature:

The Personal Car Communicator (PCC) is your car key’s smart connection with your Volvo S80 applying the latest in two-way radio technology. When in range, you’ll always know the status of your car. Locked or unlocked. Alarm activated or not. If the alarm has been activated, the heart beat sensor will also tell you if there is someone inside the car. The PCC also includes keyless entry and keyless drive.

Hello stealthy readers

February 19th, 2007 10:49pm

Hello, dear readers. I had lunch with some friends the other day and they mentioned that I hadn’t posted in a while. Sorry I haven’t been paying much attention to this site lately, other than knocking back comment and link spam. I recently saw that Google Reader is starting to report subscription statistics, which prompted me to take a look. It’s been a while since I looked over the server logs, and I was surprised at the number of RSS subscriptions that have accumulated (i.e. it’s more than I can account for by friends, family, and random acquaintances). I didn’t know you were out there, but now that you’re decloaked and I can see you, I wanted to say hello.

Back to school 2006

Back to School 2006
Today is the first day of school in Palo Alto. It feels like we just started summer vacation, but it’s fun seeing everyone after the break. I’m always surprised by how much the kids grow in just a few weeks.

Amazon aStore - custom storefronts for Amazon affiliates

August 20th, 2006 8:48am

Amidst the speculation about the Amazon Unbox video download service, Amazon has quietly launched aStores, a service providing custom online storefronts for Amazon affiliates. (You may not be able to view the link unless you’re an Amazon affiliate.)

aStore by Amazon is a new Associates product that gives you the power to create a professional online store, in minutes and without the need for programming skills, that can be embedded within or linked to from your website.

Here’s a link to their demo store.

You get to pick up to nine “featured items” to put on the home page of the store, choose product categories, and add reviews and editorial content. The shopping cart and fulfillment are handled by Amazon, with standard referral fees going back to the affiliate. There’s a browser based interface for building a store on the Amazon Affiliates site. The resulting store can be hosted by Amazon or on your own site.

More on the America Online search query data

August 7th, 2006 7:58pm

The search query data that America Online posted over the weekend has been removed from their site following a blizzard of posts regarding the privacy issues. AOL officially regards this as “a screw up”, according to spokesperson Andrew Weinstein, who responded in comments on several sites:

All –

This was a screw up, and we’re angry and upset about it. It was an innocent enough attempt to reach out to the academic community with new research tools, but it was obviously not appropriately vetted, and if it had been, it would have been stopped in an instant.

Although there was no personally-identifiable data linked to these accounts, we’re absolutely not defending this. It was a mistake, and we apologize. We’ve launched an internal investigation into what happened, and we are taking steps to ensure that this type of thing never happens again.

Back from the mobile office

August 3rd, 2006 1:50pm
At the mobile office Ocean kayaking at Malibu

Spent most of the past weekend on the beach in Malibu. Emily and I tried a little surfing, ocean kayaking, and also got a good look at some dolphins while we were paddling around.

I brought the Thinkpad, but left the charger at home, the idea being to limit my computer use while on vacation. We decided to stay a couple extra days, so I was effectively offline after running on batteries for 5 hours or so. Next time I’ll bring the charger anyway.

If you’ve been having trouble getting at this site while I’ve been away, Dreamhost posted a narrative of their recent adventures in data hosting, some of which have been power-related, and some not.

Google is having problems this evening?

July 26th, 2006 8:09pm

This evening I’m getting slow response or connection timeouts from Google for the past half hour or so (20:30 - 21:00 PDT). Usually this means that the local network is having problems, but other major sites (Yahoo, CNN) are running as quickly as ever, along with various SSH sessions around the world, so it seems to be specific to Google.

So far I get slow or no response from the main search page, Gmail, Adsense, Adwords, Analytics, and Finance.

Pages that do respond are coming back in 10+ seconds, and some pages are loading without graphics or with templates only and no content.

Anyone else seeing these problems? This is the first time I’ve seen Google unusable for more than a minute or two. (Unlike this site, which has been bouncing up and down due to problems at Dreamhost lately).

Search referrals - July 2006 snapshot

July 24th, 2006 9:07pm


Here’s a quick snapshot of incoming search engine referrals for the past few weeks. Compare this with another post last year on search engine referral share, recently referenced in a post at Alexa noting the discrepancy between the published search engine traffic reports and anecdotal observations by webmasters.

Is it just me, or are these charts a bit goofy? Does Yahoo really still have 23% of the search market? Is Google at less than half the search market?

I don’t believe it. Any webmaster will tell you that Google represents almost ALL of the search engine traffic. Yahoo is nowhere near 23%. Just read the blogs, here, here, here and here and on countless other blogs.

Already at 82% last October, Google has increased to even more of the incoming search traffic (92%) here, largely at the expense of “Other”. In the fall, it looked like those were mostly miscellaneous Chinese search engines, so perhaps my site is not getting indexed or ranked well there anymore, or Google is picking up market share, or both.

Who carries three cell phones?

July 20th, 2006 10:09pm

IMG_6298
I was out for dinner at Fukisushi in Palo Alto this evening, enjoying some excellent spider rolls and giant clam sushi. A few minutes after we were served, a young couple came in, perhaps meeting for a date after work. At first I noticed that the man had the same cell phone (a Nokia 6682) as my wife, as he took it out and set it on the table next to him. Then he took out a Motorola Razr, flipped it open, and set it on the table next to the Nokia. I’m thinking that this is somewhat geeky and he should be paying more attention to his attractive blonde companion, but he looks like an engineering or tech operations kind of guy, and this is Silicon Valley, so maybe he has a work phone for being on call and a personal phone. But then he pulls out yet another phone, flips it open and sets it down next to the other two, creating a sort of mini-console of cell phones on the table next to the sushi plates.

Hello India, we’re still here…

July 18th, 2006 8:58pm

…but other sites are apparently blocked.

There are a fair number of readers here from India, where some ISPs have started blocking many blogs, including all of Typepad, Blogspot, Geocities. So you might have thought this site was also blocked if you came by yesterday, since you would have gotten something like “Connection refused” or a similar error message.

Fortunately / unfortunately, it’s just Dreamhost having some hardware and network problems, which took down many of their clients for several hours yesterday, and is still behaving badly today.

On the care and feeding of online forums

July 18th, 2006 8:36pm

IMG_6402
I’ve had two online forum transition experiences in a week now. It’s interesting to observe how quickly an existing user base can be fragmented or even lost altogether.

The Yahoo Finance message boards uproar continues. Now that I’ve tried it more than once during the past few days, I’m still finding it difficult to scan quickly. More importantly to Yahoo, there are signs of mass migration to other message boards by very active participants looking for a new home. Much of the flock may still settle back at Yahoo, but it looks like there’s been a lot of people checking out the alternatives during the past few days.

Yahoo Finance Message Boards upgrade - ugh

July 16th, 2006 9:55pm

Dropped by the Yahoo Finance message boards this evening to scan through comments. The Yahoo Message Boards have been around in the same form for nearly as long as Yahoo, and for the past several weeks Yahoo has been testing a new format, which I find hard to read. Fortunately, there was a link to return to the original version, and I think it’s been popular.

Sometime over the weekend, all Yahoo Finance message boards have been upgraded to the new version, with no way to get to the old version.

This post captures the sentiment of many members:

IMPORTANT MESSAGE FROM YAHOO!
Hi, I am the Project Manager for the new Yahoo Message Boards. I just wanted to let you all know that we will be adding even more new features to the stunning new boards next week:

What was Zidane thinking?

July 9th, 2006 3:28pm


France lost the final match of the World Cup to Italy, on a 5-3 penalty kick shootout after a 1-1 tie through regular time and two 15-minute overtime periods. Penalty shootouts can be a bit random, so either team could have won, and it was a fun game to watch since I’m not partial to either side.

More interesting to me than the actual outcome of the game is Zinedine Zidane, captain of the French side, who headbutted Marco Materazzi from the Italian team, which got him red carded and thrown out of the game during the second overtime. Not in the middle of play action, mind you, but while walking back down field between plays, so it was completely pointless in terms of advancing the game for his side.

How to find out who watches Rocketboom

July 5th, 2006 8:49pm


I’m amazed by the volume of discussion about Amanda Congdon, Andrew Baron, and the history and future (or not) of Rocketboom. I’m looking forward to seeing what either or both of them do going forward, like everyone else, but have nothing to add to the discussion other than best wishes.

However…the flap is also having the side effect of showing that just about everyone I “know” online has been watching Rocketboom. Check out the Technorati search for pointers to Amanda’s departure post and see how many names you recognize. Who knew?

Update 07-06-2006 16:20 PDT: Rocketboom the comic
Update 07-12-2006 21:42 PDT: Rocketboom is back on the air with new host Joanne Colan, here’s her debut.

Bell Labs Holmdel to be demolished for new office parks

July 5th, 2006 8:15pm

I’m surprised to read in Engadget that the old Bell Labs Holmdel research facility is slated to be demolished and turned into three office parks. I recently tossed out some old project papers from the days when AT&T still ran Bell Labs, and I had occasion to visit the site from time to time.

Aside from the long history of really cool projects there (radar, sonar, cosmic background radiation, cell phones, networking, etc), the building (designed by Eero Saarinen), is huge (six stories, two million square feet), and visually striking. Externally, it sits on a large parcel of land by itself, making it hard to get a sense of scale as you approach. Internally, the lobby atrium is vast, open to the ceiling, and surrounded by chrome, gray, and fluorescent-lit mezzanine floors. Stepping inside felt a bit like landing in the Death Star.

As interesting and historic as the building is, what I really miss is the broad scope and scale of activity at the pre-divestiture AT&T Bell Labs. The closest thing to it today is probably at Google, funding a lot of motivated smart people with its massive stream of ad revenues, trying out a lot of interesting but not always commercially viable ideas. I always thought Microsoft could have done more along these lines with revenues from Windows and Office. You pretty much need monopoly-level profits to fund big private research for any length of time.

Gnomedex 2006

July 2nd, 2006 10:57pm
IMG_6465 seattle-alaska-way-twilight

Returned this afternoon from Gnomedex. There was a lot of external interest in John Edwards’ session, which made the front page of the Seattle Post-Intelligencer on Saturday.

For myself, I enjoyed getting away for a few days to think about blogs, social media, and also enjoying Seattle. It was interesting to meet various bloggers in person. Mostly good, although from time to time I wished for the super remote from “Click”, to turn down the volume or fast forward.

watching the world cup at gnomedex

There wasn’t a World Cup video feed on the first day of the conference, so Jeff Clavier and Halley Suitt offered to sponsor a big screen television at the conference center, which was running on the second day for the England-Portugal and France-Brazil matches. Conveniently, the dramatic penalty shootout ending the England-Portugal match started just after a session break, allowing many fans of the English side to be disappointed in real time. Jeff was pleased with France’s win, however. No conference feed in the World Cup TV room, but the IRC backchannel was busy.
