11n FUD? How interesting. The manufactures of 11n devices make up the majority of the standards committee. They aren't going to add new hardware requirements to the standard. Finalization is simply a matter of bureaucracy. Meanwhile, have you noticed how all the devices interoperate now? Did you spot the Wi-Fi certifications? It's already a working standard.

Do you honestly expect your AP to stop working with your laptop when they file the final papers? Will the backward compatibility with 11g and 11a disappear? No. And FYI, the final standard standard will work with draft 2.0 too. Your concerns were valid with pre-N equipment, but now it's unfounded.

Wouldn't that be overkill? All 11n devices do MIMO currently - if a future device does not, it won't have a > 200Mbps number on the box. Greenfield is insignificant in practice. You just want to look out for 2.4 and 5 GHz support, or dual radio if you need that. I realize that retailers try to fool people by putting just a giant 11N on the box, but if you read closer you'll see if 5 Ghz, or 11a compatibility, is included.

As far as maintaining a website, most of these products come and go too fast to keep up with. The user could write down model XGY-2000T and find a XGY-2001B when they get to the store. Better to just read the small print on the box.

B and G use the same channels, and 11n can use G or A channels. So, 'NA' is open too. Another advantage of the A channels is that there is less channel overlap and a shorter range. In a small house, 11a will still cover it all, but neighboring houses will become weaker interferers. In a condo situation, 11a is ideal.

My second choice if it's a single user, and only for internet browsing, would be 11b (or 11g limited to 11mbs rate - same thing). It really does seem to work better in practice, although I expected rate adaptation algorithms to find the best rate for my 11g connection, it is not so. 5-7 Mbps should be enough for this user anyway.

Sadly, retailers have been selling us b/g-only for a long time to save a couple of bucks, and nobody seems to care.

"i love how intel is touting how (even though wifi has been tech since the late 90's early 2000's) that they finally got around to making it work over "long" distances."

I love that they chose to make a big deal about a Wi-Fi solution when WiMax was supposed to be here already. Wasn't it this time last year when they were talking about WiMax adapters being standard on laptops? ...and over long distances too?! This the kind of tech that Intel should kill, not promote... if WiMax were really on its way, that is.

It's funny.  Laugh.

The Coevolution of Lice & Their Hosts 179

eldavojohn writes "It might be an uncomfortable subject but parasites are an interesting subject when it comes to evolution. Ever wonder if pocket gophers have lice? Well, they do. And most interesting of all is the evolution of these lice mirroring the evolution of gophers. To study the genes of lice may shed just as much light on evolutionary trees as studying the genes of the actual host the lice has evolved to. The most unsettling result from these studies is that human head lice and human pubic lice (crabs) vary so greatly that they are in two separate genera. There were similarities between our pubic lice and the lice found on gorillas. Scientists came to the conclusion, which they published today in BMC Biology, is just as striking as their earlier one about head lice. But it is hardly the same. We did not get pubic lice from other hominids. We got them from the ancestors of gorillas."
