I thought I felt a disturbance in the Force this morning. The source: Google. The search giant dropped an enormous bomb on me today: Sidewiki.

Sidewiki is a browser tool — it plugs in to Firefox or Internet Explorer (no Google Chrome support for a Google tool? How odd!). It allows you to write and read annotations to any Web site. Let me say that again: you can add content (or read content added by other people) to any site on the Web using this tool.

The additional information appears in a sidebar to the left of the body of the Web site (the tool shifts the rest of the site over to the right in a squished view). The data can include thoughts, comments and even active links to other Web sites. More on that later.

The only way you can read added material is to download the tool and activate it yourself while viewing a Web page. User-generated content won’t just pop up on the site on its own. But this tool could conceivably make a huge impact on the Web.

You use explosion welding to join dissimilar metals into a single sheet at 2,000,000 PSI, as demonstrated here:

My lovely co-host Sarah sent me a link to a cool National Geographic story about animals in prehistoric Egypt, in the city of Hierakonpolis. (I didn’t know anything about Hierakonpolis before I started researching it this morning. That’s the thing I love best about doing the history podcast and blog: learning new stuff. Plus, then you get to talk about things like koro in the elevator and have people from the radio station in the penthouse stare at you.)

The City of the Hawk came before all the things I learned about during that middle-school King Tut phase — it’s a Predynastic site, and what archaeologists have found there gave us our understanding of how the ancient world of Egypt came to be. If the name Hierakonpolis sounds familiar, it might be because of the Narmer Palette, which is known as the first political document in history. (It’s a flat plate that may or may not depict the unification of Egypt — pick a side and fight with an Egyptologist about it.)

One of the many, many events I missed during Dragon*Con ’09 was an attempt to break the Guinness world record for the most people doing the dance from Michael Jackson’s “Thriller” video. I had both practice sessions and the record-breaking attempt marked on my calendar, and I made it to none of them. I consoled myself by thinking that when the results came back — and with 903 participants, surely they’d win! — I’d write about the achievement. I didn’t know that a group of 13,597 dancers had just tried to break the record in Mexico, and I learned yesterday that the record now lies with them.

The Atlanta Journal-Constitution’s Inside Access blog noted that the Dragon*Con organizers had contacted a lawyer because the Mexico team hadn’t followed the rules. Wondering just what was up with that, I e-mailed organizer Lauren Leasure, and early this morning, I got a response that was considerably perkier than what I’d expect from someone who’d just come out on the wrong side of an adjudicating panel. Find out what she said after the jump.

As cold season approaches, the chances of catching a cold go way up. “Winter” and “colds” go hand in hand for most people. In fact, it is possible to catch a cold several times in one winter. Each time you are succumbing to a different strain of cold virus. Is there anything that you can [...]

While politicians and economists debate whether or not the recession is truly over in the United States, many average Americans are still struggling with making ends meet. Rounds of layoffs and an increasingly competitive job market create challenges for job seekers. For some, months may pass without any leads. I think most people would become discouraged in such a situation. I also think most people would jump at a seemingly legitimate job offer in a heartbeat.

That’s a big problem. There are many scam artists who target job seekers. For one thing, people looking for a job are vulnerable — they are looking for a way to improve their lives. For another, it’s natural for humans to feel excited and happy when an opportunity arises. It’s not necessarily natural for us to step back and examine the opportunity critically. But that’s exactly what we need to do before responding to a job opportunity.

Last night, I received a tweet about a supposed work-from-home program headed by Google. I was immediately skeptical — I follow Google pretty closely as part of my job and I hadn’t heard of any plans to create such a program. What’s more, the tweet claimed that the program had been covered in major news outlets. Again, that seemed odd to me; surely I would have heard about such a thing! I decided to investigate.

On Tuesday afternoon, the Huffington Post revealed it had learned that Libyan leader Muammar Gaddafi would be pitching his tent on Donald Trump’s New York estate when he comes to the U.S. for the United Nations General Assembly. The town is trying to bar the tent due to permitting issues, and the estate in question isn’t even Trump’s primary residence, but I couldn’t help imagining how their hypothetical time together would go. Would Trump carry fresh towels out to his houseguest’s tent? Would Gadaffi anger Trump by playing loud music at all hours of the night? Who would throw the first hissy fit about length of time spent in the bathroom?

The delicate dance between host and houseguest can be a complicated one, even when real estate moguls and Libyan dictators aren’t involved.

We all know that if something looks too good to be true it probably isn’t, and the mouth-watering imagery used to sell food never is. But sometimes the yawning chasm between what’s in the ad or on the packet and what you see on the plate in front of you exceeds the usual artistic licence [...]
