Here’s a weird one. it turns out that ROFLCon, dedicated to all those Internet fads, was held at MIT this past weekend. Found via the Mozilla blog: Firefox Spotted at ROFLCon (look there for a picture of a life-size Firefox mascot with Tronguy).

Scientists have built a computer model of the Neanderthal vocal tract based on fossils, and have simulated the kinds of sounds they could have produced. Ever since I read Robert J. Sawyer’s Neanderthal Parallax novels, I’ve been fascinated by the idea that there were two distinct human species, living side by side, for perhaps thousands of years. What happened to them? Did our ancestors kill them off, or interbreed with them? Did they fail to adapt to a changing climate? (via Slashdot)
On a related note, it seems that Expelled, the anti-science propaganda film that actually invokes Godwin’s Law by claiming that “believing” evolution leads to Nazis, opens this weekend. I’m curious to see how badly they misrepresent things (it’s always best to look for yourself, instead of just taking other people at their word—that’s the whole idea behind science, after all), but I can’t bring myself to support them by actually giving them money. Meanwhile, Expelled Exposed is interesting reading.
In software, dria.org explains why the AwesomeBar is awesome. That’s the nickname given to the new address bar in Firefox 3, which lets you search your browser history as you type. It’s the reason I never went back to Firefox 2 after trying out one of the later FX3 betas, and why I’ve installed Fx3b5 on two more machines. The Opera 9.5 previews have a similar feature, but Firefox’s implementation is better visually. It’s easier to spot the page you want, and over time, it learns which pages you visit more often. It’s so much faster to type a word or two than to hunt through the bookmarks menu. (via Asa Dotzler)
IEEE has an article on how copyright law applies to websites, What Can You (Legally) Take From the Web?
Finally, ***Dave relates an incredibly cool story of going to see Avenue Q and what happened after the show. I had no idea that (at least in New York), the “Give Me Your Money” segment was actually collecting for a charity.
Apple Updates Software Update, Addresses Criticism
In conjunction with the Safari 3.1.1 security release, Apple has also released a new version of Apple Software Update for Windows. With version 2.1, they’ve taken the opportunity to fix one of the problems that caused so much criticism last month.
It now shows two lists: one for updates, and one for new software. This takes care of one of the three easy steps that I culled from discussions back in March:
- Separate updates from new software and label them clearly. Done.
- Leave the new stuff unchecked by default. Bzzzt! Try again!
- When run automatically, don’t pop up a notice more than once for each piece of not-installed software. [Edit:] Done.
Unfortunately the new software is still checked by default, but one hopes that the separate list would be enough to make people stop, look, and make a conscious choice as to whether or not to install it.
I don’t know yet how it handles new software when run automatically, or whether they’ve made the ignore option apply to an entire piece of software rather than a specific installer. I’ve taken iTunes off the ignore list and set it to check daily so that I can find out. [Edit:] I haven’t seen it pop up in the last 24 hours, and according to eWeek, “Apple will now only prompt the user if there are critical security updates available.”
Avatars!
Since Gravatar was bought by Automattic, the service has been a lot more stable. I had already re-enabled them on this blog before WordPress 2.5 came out with built-in Gravatar* support.
Not everyone has a Gravatar, though, so many comment threads just show the default icon, over and over. Not only does this look boring, but it misses out on the whole point of using an avatar: providing an easy at-a-glance visual distinction between each author.
When I first used Gravatars on this site, I set it up to use a giant first initial as a fallback. Now, I’ve been trying out two plugins that will automatically generate avatars for people who don’t have their own:
- Wavatars builds up cartoony faces using geometric shapes. Interestingly, it’s by Shamus Young, author of the screencap-based webcomic DM of the Rings and writer of Chainmail Bikini.
- WP_Identicon sounds like a Transformers faction, but produces a geometric pattern as inspired by Don Park’s Identicon, which built a similar image based on a visitor’s IP address. The same author also has one that generates cartoon monsters, which appears to be one of the earliest implementations of this concept.
These plugins will use a Gravatar if available, or else generate an image based on the commenter’s email address (if supplied). That means each comment by the same person should use the same image. Other blogs using the same plugins at default settings will come up with the same avatar for each commenter, as well. The images are stored in a cache, so each only has to be generated once.
Once I made sure both plugins worked, I showed the results to Katie. We ended up settling on Wavatars, since faces are easier to recognize than patterns. (Though the patterns are really cool!)
You can try out the automatic avatar by leaving a (relevant, please!) comment on any post. Or you can run over to Gravatar and set up an icon of your choice!
*What’s a Gravatar? The intent is to be a Globally Recognized Avatar. You upload an image to Gravatar and associate it with your email address. Then any site with Gravatar support will be able to display your image next to your posts. Right now it’s mostly used in blog comments, but it could easily be worked into forums, wikis, etc. The Gravatar Blog mentions other uses they’ve seen people apply it to, such as plugins for Thunderbird and the Mac OS X Address Book
Note: I did notice one important drawback to the WP_Identicon plugin: it’s very inefficient at generating the images. When I first visited posts with long comment threads, like Another One Bites the Dust (174 comments) and Songs Not to Play at a Wedding (87 comments), WP_Identicon took over a minute to generate all the icons and maxed out the server’s CPU. Sure, the images are cached, so it’s only really an issue when you first install the plugin (unless you get a lot more people commenting at once than we do here), but to compare, Wavatar on an empty cache finished the same posts in just 4 seconds and 2 seconds, respectively.
Linking the Real and the Virtual
The WaSP Buzz’ article on a new mobile web browser test made mention of phones that can read QR Codes—one of several types of 2-D bar codes that you see on things like shipping labels. In this case, the idea is that you can point your phone’s camera at the QR code and it’ll decode it and send you to the appropriate URL.
My first thought was that this was just like the CueCat, which was a bar code scanner that you could plug into your computer’s USB port, then scan bar codes in magazines, or on cans of soda, or whatever, and it would tell your computer to bring up relevant information. It was marketed in the late 1990s, during the tech boom… and it was a total flop. No one wanted them. The company went under and had millions of the little scanners sitting around unsold.
But now there are multiple schemes in use for object hyperlinking. In addition to graphical codes, there are RFID tags, GPS coordinates, and short text codes that you can easily type into an SMS message or a web portal.
So why is this sort of thing working now, 10 years later? Is it a societal change? Was the CueCat ahead of its time?
I think there are two reasons:
- CueCat was a single-purpose device. All the applications listed involve smartphones or other multi-purpose handheld devices. No one wanted a device that would only scan bar codes, but a phone/camera/browser/MP3 Player/bicycle that also scans bar codes? Sure, why not?
- CueCat was tied to the desktop. Sure, you could plug it into a laptop computer, but you’d still have to take the object over to your computer to scan the bar code. Unless you’re a lousy typist, swiping the CueCat across your can of Coke isn’t that much easier than typing in www.coke.com. As a home user, you’re not likely to be scanning a dozen objects in a row (unless you’re cataloging all of your books for LibraryThing).
All the applications listed on that page are mobile. A tagging scheme does give you an advantage when you’re out walking down the street and see something interesting. It’s much easier to punch in a short number than to try to type a URL on most phones, easier still to point your camera at a graphic, and dead simple to pick up an RFID tag or pull in GPS coordinates.
Update 2024: It’s funny: in the early 2010s I remember jokes about how no one outside of a marketing department had ever scanned a QR code, but now they’re all over the place, both for linking objects (a sign on a fast food door to go to their online ordering service, a code on an instruction manual to open a site with changes since printing) and for sending data between devices (communications apps, 2FA apps, starting a download on a mobile device using a QR code shown on a desktop display).

Apple Software Update: a Simple Solution
I appreciate the fact that Apple provides a single updater for all their Windows software. It’s nice to consolidate things a bit with the profusion of updaters for what seems like each and every application (sort of like how every mobile device seems to need its own charger). But it has its flaws. I’ve mentioned some broken UI design, but the most annoying thing is that it tries to install new software instead of just updating what you have.
At work, I have QuickTime and Safari for development purposes. I don’t have iTunes. I don’t need it. I don’t even have speakers hooked up to the computer. But every time a new version gets released, it shows up in the Apple Software Update list, and I have to tell it to ignore it until the next time they update iTunes.
Now that Safari for Windows is out of beta, it’s doing the same with Safari*. And people are complaining. People like John Lilly, CEO of Mozilla, who sees it as an anti-competitive measure that dilutes users’ trust in software updaters.
Personally, I think there is a problem, but I hardly expected it to turn into the firestorm it has, with Asa Dotzler, c|net, digg, Techmeme, [edit] and now Slashdot, [edit 2] Daring Fireball and Wired (it just keeps going!), and dozens hundreds of commenters entering the fray.
There’s a simple solution, and it’s one of those rare cases where Microsoft gets something right in their software that Apple gets wrong.
- Create a separate section for software that isn’t already installed, and label it clearly. It can be in the same list, as long as there’s a separation and a heading.
- Leave the new stuff unchecked by default.
- Added: If set to check automatically, don’t pop up a notice more than once for each piece of not-installed software.
That’s it. Done. Apple still gets to leverage their installer to make people aware of their other apps, but there’s no chance of someone accidentally installing Safari (or iTunes) by accident because they didn’t read the list too closely. Take a look at Microsoft Update and how they (currently) offer Silverlight. It’s in a list of optional software, and it’s not checked until you choose it.
That’s all this really comes down to: sensible defaults and proper labeling.
Update: Well, two out of three ain’t bad.
*I have to admit getting a kick out of the title, “Apple pushes Safari on Windows via iTunes updater,” because my problem is that they’re pushing iTunes on Windows via their Safari updater. It’s a matter of perspective.
