0 is the identity element for addition. You can't really define the concept of "-1" without the concept of zero. Of course, it's also nice to have multiplication, with its identity element 1. Now you have some basics for building an algebra, and you can eventually construct fields like rational, real and complex numbers, and beyond.

That's a decade or two out of date. Maybe more. Here's this weekend's list of sex and fetish events in SF. There's a nostalgia tour for tourists of SF's sex history, and a screening of porn films from a Berlin festival. Yawn.

Flickr does pretty much all of this. You can use a Yahoo account, a Facebook account, or a Google account to sign in.

Then make a Flickr group (it can be private or unlisted). Everybody can contribute photos to the shared group and geotag them. Then everyone else can see them on a map. You can also search for tags by keyword.

Done.

And yet you bought and use Windows 8 rather than abstaining and hitting MS in the pocket book where it counts. They really learned a lesson there.

Yep. Dumped all my tech stocks today. This is going to be real ugly. It'll be 10 years before the dust settles.

I'm not seeing this. It's a dull period for San Francisco. The first dot-com boom was more fun. Connecting up everybody and everything was important. This boom is all from ad-based companies, and most of what they're doing is rather banal. So are many of the people doing it.

Almost all the artists who need more than a desk and a laptop moved out years ago. SF used to have lots of big empty warehouse and factory spaces that were used for art projects and wild parties. That's what SOMA was. Those are gone, replaced with "live/work lofts" or giant bullpen workspaces.

I do not get why tech people want to live in the Mission. I've had friends there for years, and it's tolerable, but not a place to live in by choice. Wednesday I went to a stand up comedy improv thing in the Mission where people tried to put together presentions from random PowerPoint slides. Heavy bouncer presence outside because it was right next to a service center for homeless people. The comedy sucked, too. That's what the tech crowd is bringing into the area.

Here's a typical Mission location, one which also happens to be a Google bus stop. "Cafe la Boheme" has crappy food, and it's had crappy food for years. The place with the graffiti is an upstairs dance studio which is hanging on. "Chinese Food and Donuts" isn't very good at either. That corner has looked the same for many years. There are some decent restaurants a few blocks over on Valencia, but not at this corner. There are cool places to live in SF, but this isn't one of them.

The next Vesuvius is about to erupt under corporate headquarters.

KEEP CALM

and

DO NOTHING

So... the emails warning of the threat were treated as spam? That's kinda funny.

Honestly, how hard can be be to look after the source of executive pay?

and pissed in a number of esoteric theories cheerios

I'm not inclined to think this is the case. I think their result was many orders of magnitude over the previous measurement because there was only one other measurement made in this frequency range. The previous experiment was a torsion bar experiment done in a modest-sized lab. According to the LISA folks:

In general, a ground-based interferometer is limited to frequencies above about 10 Hz because of seismic noise

I didn't read the torsion bar paper to see what they did to eliminate noise sources.

The two used much different frequency regimes. The Stanford paper looked for waves with periods of 30 minutes to 24 hours. The one in the article looked for waves with periods of 1 to 20 seconds.

They'll make you an offer you can't refuse.

Chris Christy isn't the only one with machinations.
