I just got on Google+, and the Circles concept definitely moves the ball forward, but my heart sinks a little at having yet another disconnected social identity. It’s been said before, but it’s worth saying again – social networking needs to be an open, core internet standard like email. You can live on Facebook, Google, Twitter, wherever but your social graph should be independent of any specific service.

I don’t mean this in any (well, OK, a little) granola crunching open source way. Companies should compete to the death on their social graph implementation and added value. But the actual data on who your friends are should belong to you and should be both portable and interoperable. I should be able to friend someone on Google from within Facebook and share core items in both directions. If I get fed up of Facebook I should be able to move my graph and central identity elsewhere.

We’ve got OpenSocial, strangely not mentioned in the same breath as Google+, and Open Graph which is open for things but not people. Also FOAF, XUP, and other possible foundational standards. Of course the barriers here aren’t technical.

Altly wants to be Pepsi to Facebook’s Coke. I’m waiting to see what it tastes like, but it doesn’t sound like they’re itching to change the game.

Diaspora is an interesting project, but running instances (pods) of a social network is the wrong level of abstraction.

Of course ‘owning’ the graph is tremendously valuable and it’s hard to see Facebook giving this up anytime soon. If Google really don’t want to be evil they should use Google+ to liberate us from the tyranny of walled social gardens. Unless it turns out to be another Buzz or Wave in which case it’s down to us.

Algorithmic trading is getting a little out of hand:

“For high-frequency trading firms that use powerful computers to pop in and out of positions in milliseconds, so-called collocation, or "colo," is a pricey necessity. That's because trade times are approaching the speed of light, and the only way to make light reach its destination quicker is to shorten the trip.” – smartmoney.com

This kind of trading accounts for an estimated 70% of US market volume. It’s completely disconnected from any kind of intrinsic value and only creates a benefit for the HFT firms and the exchanges that pocket the fees and exorbitant server hosting fees.

It’s like installing an ATM skimmer on the capital markets.

I think we need some way to enforce a hold period to discourage this business model. It could be an actual window that forces you to hold stock for a few days before selling (actually a few minutes might help), more likely a tax or fee that is prohibitively high at the millisecond turnover rate but ramps down to nothing after a week.

Three recent Catfood Software updates:

Catfood Earth 3.10 includes rotation to longitude / solar time, volcanoes, a screen saver, time zone updates and more. Catfood Earth uses satellite imagery and a variety of data feeds to render jaw-dropping live desktop wallpaper.

Catfood PdfScan 1.10 saves your selected paper size and feeder choices. There is also an option to keep PdfScan open after saving a scan, something that had been bugging me when slogging through large digitization projects. PdfScan is a free tool for scanning stuff into a PDF file.

Catfood Weather 2.00 includes weather alerts and an updated UI. Catfood Weather provides a free, taskbar based weather forecast for US locations.

I’ve been working on an update to Catfood Earth. Several people have asked me to draw the International Date Line on the time zones layer but I’ve struggled to find a decent source for the coordinates of the line segments. I finally ended up manually digitizing the version of the line that appears on Wikipedia. The original is licensed as Creative Commons Attribution-Share Alike 3.0 Unported so I’m making the coordinates below available under the same license:

This looks great for Catfood Earth. Please take the coordinates with a pinch of salt if you’re designing a cruise missile guidance system or something.

It’s kind of clever because not only do you have to read the ad but you also have to type part of it in so their catch phrase is more likely to stick.

It’s mostly throw up in your mouth, because it takes a while to even figure out that this is a CAPTCHA and because you know that you could be digitizing books instead.

Spotted on boxbe, although some light Googling suggests that this has been around for a few years.

The path around Lake Merritt is a pleasant hour-ish hike in downtown Oakland. In addition to a startling variety of waterfowl (apparently it’s the first official wildlife refuge in the US) Lake Merritt is the home of Fairyland which I fear I may be forced to visit in the not to distant future.

(3.76 miles, 1 hour 2 minutes, average 3.64 mph, view in Google Earth).

Hike starts at: 37.808922, -122.263224.

After decades of ethnographic and quantitative research into the medical skills of Canis lupis familiaris I can finally publish a detailed guide to canine medical lore:

1. Lick it.
2. If, for any reason, step 1 fails to work eat grass until you throw up.
