I've blogged before about the prospect that the plummeting cost and size of sensors will result in their being embedded into bulk materials during production of those materials. Consumers of items built with the raw materials will have the convenient option of using the sensors or just ignoring them. But manufacturers do not "throw in" extra parts because they are almost zero cost: in competitive mass markets, all costs count. Rather, manufacturers "throw in" optional parts in order to overcome the consumer's hesitation at the point of sale. The point of sale is the sale.

I am a completely hooked news junkie. I watch every talking head on every channel. But something that has been bothering me for years, is that Bill O'Reilly of Fox News uses the slang "Grand" or "Gs" when he means thousands (as in, "25 Grand" or "25 Gs" meaning 25 thousand dollars). I find this eminently cringeworthy. For at least 20 years, people use "K" for "thousand," partly because of the metric system, and partly because of computers (as in "kilobytes"). He sounds like a 1920s antique talking about "Gs". So, I sent the following letter to Mr.

As most of our readers know, I am an avid Ham. One of the most-read newsletters in Amateur Radio is the ARRL Letter. One trend that I have noticed in the Letter, is that the frequency of CubeSat launches has risen so steadily, that nearly every ARRL Letter reports at least one; and some Letters are more than half-filled with space-related articles. The latest Letter was no exception, reporting on the successful launch of the ARTSAT1:INVADER satellite (now officially OSCAR 77).

My friend Kash Badami, one of the original techies at MarkLogic who left several years ago to create his own practice, forwarded me this link to an article about the architecture of healthcare.gov . You can decide for yourself how much you believe the explanations for the site's poor performance. But I will bet that this article contains more specific information about the architecture of the site than you have seen anywhere else.
In a nutshell: 48 MarkLogic nodes and an Exadata.

As I write this, the investigation continues for the missing Malaysian Airlines Flight 370. I have absolutely no theories on this tragic subject. However, I would like to take a moment to praise one of the unsung heroes in the investigation, Inmarsat, whose engineers were the first to discover, by reviewing the history of satellite pings, that the plane changed course and flew for seven hours after its last ACARS contact.

Today, Senator Rockefeller was in the news for objecting (via a letter to ICANN) against the two companies that have applied for ".sucks" domain name registration (see below).
First of all, a reminder of how we came here: originally, under the IPV4 system of domain name registration on the Internet, there was a paucity of domain names. "Cybersquatting" and other shenanigans affecting the relatively small number of meaningful domain names for a given company were a real concern.
However, tempus fugit.

Like a lot of people in my field, I look daily at Amazon Books to see if anything new is coming out that I care about. Of course, I also do Internet searches, and I also rely on professional courtesy and other channels of information, but I always look on Amazon, too.

There are more CubeSats in orbit! WOO-HOO!! CubeSats are the shortcut to the Internet of Things. Satellites inspire people. People are willing to invest a little effort to learn how to talk to a satellite. The feeling of freedom, and of self-sufficiency, that you feel, the first time you talk to a satellite with a 5W hand-held unit and a home-made Yagi antenna, is indescribable!
Set forth below is a direct copy from ARRL. I am copying it on purpose, so that our visitors can get used to Amateur Radio nomenclature and syntax.
