As if the current proliferation of social networks was not enough, Plaxo has recently launched its own offering called Pulse, in the best tradition of branding-via-metonymy. First of all, “Pulse”? I am generally not in the habit of checking my friends’ vital signs several times a day, so that kind of got lost on me. Maybe they could have done better with Spasm, Borborygm, or ultimately, Omphaloskepsis, since that’s basically what social networks are.

Anyway, what I really wanted to say is that Plaxo Pulse fails. Out of the gate. Dead on arrival. Why? Well, ever since it launched I’ve been receiving notices that such-and-such has added me as friend or wants to add me as a business contact. These notices provide a link to go to Pulse site and confirm the connection. Not recognizing one of the names, I decided to clicke on the link to check it out, but all I saw was a page that said, “Not a member yet? Sign up!” Are you freaking kidding me? You expect me to sign up just to see who wanted to add me as a contact? No thanks, Pulse. You lost me at “click here”.

Now that Yahoo! Photos is closing down, Flickr is going to experience another surge in membership. It is already the most popular photo sharing service that matters (forget about Photobucket and such), and it has an unparalleled API. So with that in mind here’s the first of Andrei’s Web 2.0 Laws.

Law #1: As the number of mashups increases, the probability of a new mashup not using Flickr approaches 0.

Proof, what proof? This is not math or physics here, this is Web 2.0. But do go and take a look for yourself; Flickr infiltration is everywhere. And if you find a mashup that doesn’t use Flickr API, then there are only two explanations: a) the authors have thought or are thinking about using Flickr in one way or another; b) they are Amish.

I, for one, welcome our new megapixel overlords.

That is indeed the title of the article on Ohloh, a site that collects information on open source projects and gathers statistics by analyzing the source code of those projects. So far they’ve indexed over 3,000 projects and their conclusion seems to be that among Web scripting languages, PHP is the undisputed champion (as measured by the LOC count).

Measured purely by the number of new lines of code, PHP leaves all other web-scripting languages in the dust, and continues to grow. Quite simply, one-fifth of all open source code being written today is written in PHP.

This, combined with their observation that the relative number of developers working in PHP is not increasing and that the number of new projects being started has actually decreased, leads to an interesting premise: the trend for for PHP-based projects points towards mature code bases. Meaning that the developers prefer to work with existing applications or frameworks and increase their output through updating these applications rather than starting new ones. In general, that seems to be a good trend, if one can rely on the data gathered by Ohloh. I have not done an exhaustive examination, but there are some puzzling things in the data on PHP project itself. For example, how do they calculate “man-years” for each developer? My number is 5.5, which puts me fourth on the list behind Rasmus, Derick, and Frank. I know I’ve been working on PHP longer than that. And then, Andi and Zeev are actually below me with 5.3 and 5.2 man-years respectively. The account with the most man-years seems to be our automatic changelog committer script, even though it committed a total 0 lines of usable code.

Even without Ohloh’s data, one could venture to say that the code base of projects using PHP is larger than those of Ruby or Python. A lot of that is due to the accessibility of PHP, I think, but does pure lines-of-code count give indication to the quality of said code? Of course not. I think Ohloh is providing a useful service by tracking this kind of information, but I would take its results with a few grains of salt.

Thought I’d throw a couple of fun links your way. First one is a project that almost won $5,000 prize at the last Mashup Camp. It presents, shall we say, an innovative approach to user validation combining so-called business with so-called pleasure. HotCaptcha gets thumbs-up from me any day of the week.

The other is a supremely strong candidate for the title of the Worst Music Video Ever. It is an inspired effort that immediately induces cringing expression on your face and fails to release you from its grip until (in my case) 3 hours later. Have fun.

Last week was the first time I had to do a hard shutdown on my Powerbook. It was a strange feeling. There I was, doing something that used to be a regular occurrence in the Windows world, and now it really bothered me that I had to hold down the Power button for 5 seconds and wait for my Mac to commit temporary suicide. And I was apprehensive for a good reason.

After powering back up, I discovered that my desktop (lowercase) was gone. No icons, and I could not drag anything to the background at all. I still had ~/Desktop folder but it seemed to be disconnected from the actual display. No one I asked about this has encountered the problem before, but I had a hunch it had to do with a corrupted preference file or something similar.

After much muckying around (creating a new user, making sure its desktop was operational, running Preferential Treatment over all .plist files, doing a binary sieve on the .plists to find the offending one) I narrowed it down to com.apple.finder.plist. A bit more yahoo’ing revealed that the culprit was a “secret” preference called CreateDesktop. If set to false, it tells Finder not to display the desktop. Brilliant. Somehow this got turned off during the hard shutdown and my desktop got lost at sea. Anyways, if you ever get sick of your Desktop (or want to restore it, like I did), you can change the setting via:

defaults write com.apple.finder CreateDesktop -bool <false or true>

Until later. I am going to go click on all the icons.

UPDATE: Fixed the HTML escaping of the command (the bool arguments were hidden).

Inspired by the latest entry at Yahoo! Music Blog, I registered at Last.fm and started feeding my playlist information to them via the AudioScrobbler iTunes plugin. My profile there is slowly building and I am looking forward to checking out what their customized radio station will start playing for me once they know enough of my tastes. Their recommendations so far seem to be decent, but I need to listen to about 300 tracks before the music “neighbors” become available. As a side benefit, I also put the RSS feed of the last 10 tracks played on frontpage of this site in the right hand column.

I also explored Pandora, the other service mentioned in the blog. From what little time I spent with Pandora, it seems fascinating. Created by the Music Genome Project, it allows you to specify an artist or a song and create a “radio station” that plays songs that are musically similar to the specified one. What does “similar” mean? Well, the folks at Music Genome Project analyzed over 10,000 songs of different artists and broke them down into traits, such as harmony, rhythm, instrumentation, orchestration, arrangement, lyrics, singing and vocal harmony. Given a song, for example “Volcano” by Damien Rice, Pandora will create a station that features songs with mellow rock instrumentation, folk influences, mild rhythmic syncopation, acoustic sonority, repetitive melodic phrasing, and other similarities to the original, picking things like “Smile” by Mia and Jonah and “Igloo Glass” by Holopaw. You can add more songs or artists to the station and Pandora will try to pick tracks that cover the whole gamut of what you are looking for. You can also thumbs up or down the individual songs to fine tune your preferences and build up a favorites list. I would say its recommendations range from good to very good and I definitely intend to use it as a tool for discovering new music.

Face recognition technology is getting really good. Yesterday I saw a link to Intel’s OpenCV library float through the mailing list at work and a note that someone wrote a PHP extension for it. “Interesting”, I thought. I hacked up a simple PHP script that would take an image and process it slightly to make detected regions more obvious. Here’s an example of the output. Not bad, huh? Then Jeremy tried another image, with some spooky results. Note that aside from the person, there are a couple more regions that the library thought was a face. If you look closer, the larger rectangle on the carpet encloses something that does have vague face-like features. Nice job, Intel.

Here’s another Mozilla/Firefox tip: if you copy a URL wrapped over multiple lines from somewhere and try to paste it into the address bar, you will end up only with the first line of it. To fix it, go to about:config and change editor.singleLine.pasteNewlines setting to 3 or add:

user_pref(”editor.singleLine.pasteNewlines”, 3);

to your user.js file. Now all the line breaks will be removed upon pasting.

I didn’t know that SatireWire was back until Jeremy mention it on his blog. Anyways, this interview with Ask Jeeves is one of the funniest things I have laid my eyes on lately. <wiping tears> Thanks, guys.

P.S. Maybe it’s not really back. Oh, how easily dreams are crushed.

After trying to figure out how to keep my bookmarks shareable between computers (del.icio.us, various FireFox extensions and such come to mind) I was pleasantly surprised to see the unveiling of Yahoo!’s MyWeb2 - a hybrid of bookmarking, tagging, and sharing your pages within the community of your friends from Yahoo! 360. So, all it takes now for me to bookmark something is click on the little Save link in the search results or in my browser toolbar, put in a couple of tags, maybe a note, and set the access level. But the best thing is that when I do a search on Yahoo!, its MyRank algorithm rates the pages saved within my community higher, and also brings up a list of my bookmarks at the top of the page. And it’s dead easy to import your del.icio.us bookmarks or any other RSS feed into MyWeb2. Salvation at last.
