Comment Re:Is this how they can do wifi location detection (Score 1) 237

There's a ton of misunderstanding here about what's going on. The quick answer is that yes, you degrade it if you're the only BSSID in the area (or the majority, eg bringing two BSSIDs into an area with only one).

First off, Google is trying to build out its own WiFi augmented location services so they don't rely on SkyHook's (currently larger and more robust) offering. Keep in mind, the iPhone/iPad/iPod Touch OSes are the major SkyHook clients, and recently Motorola announced they were ditching Google's smalller/less reliable location service for this very reason on their own Android devices.

Both implementations are dynamic and self-repairing. That means that if a client reports back that one BSSID isn't in the locale as two other BSSIDs it knows -are-, SkyHook/Google will immediately know that something has changed. If the majority of BSSIDs match a given location, but another has changed or appeared, it'll eventually be incorporated with time and if clients continue to report consensus. If a client comes in with GPS and WiFi is turned on, it's given priority and reports back to SkyHook the current visible BSSIDs for updating their database with the GPS data as well. Obviously, because the client has a GPS fix, it'll be given a higher weight and update that database pretty quickly.
The cool part here is that mobile devices are building out the location services data each time they use it - it's in fact evolving, healing, and getting better. Fire up Maps on any of the major platforms, and you're helping Google and SkyHook both.

I recently experimented with this myself. I moved from one location to another across town, and brought along my two wireless APs (one of them dual band N, so a total of 3 BSSIDs) and fired up location services in my new location. On the iPhone and Android clients, the initial quick fix showed me in the old location. Trying with locate me on google maps also showed me at the old location. Then cellular data came in and showed me roughly across town where I was. Then GPS got a fix, and put me very close to my real location indoors. This is how it's supposed to work. At this point, the device reports back the BSSIDs visible with the GPS fix to whatever service is in use.

I tested over the course of a few days and noticed that the iPhone client had updated the SkyHook database within a day and was now identifying - from WiFi - that I was in the right place. You can test that with an iPad (no 3G, just WiFi) or iPod Touch with location services. The Android client has taken about a week which is more surprising. You can immediately see where (based on WiFi) the google database puts you by going to maps.google.com and clicking the location button.

Both SkyHook and Google likely use a similar architecture - it's essentially two big companies wardriving and finally doing some math armed with signal strength and GPSes. Except now *everyone* is wardriving on their smartphones, and they don't really realize it.

Wow, the amount of FUD in your post brings me right back to iPhone 2G launch. In fact, you sound just like I did. Is this 2010?
1. True. But it isn't like you can't load any MP3/other file without DRM and play it back. What library draconian sync restrictions are you speaking of?

2. True, more or less. They're pretty snobby.

3. Huh? How so? Go look up how much the Nexus One unsubsidized is. $530 bucks? That's just about in line with the $600 for the iPhone non-commit. Face the reality that all phones are expensive without subsidy.

4. This is something that I initially thought, being a hardcore hardware keyboard addict. That said, when OS 3.0 came out, I went into an apple store, cleared my mind, and tried using the SMS app in landscape. Surprisingly, I founding myself texting just as fast with the landscape virtual keyboard on the iPhone as I did on my HTC Touch Pro and Mogul. Perhaps even faster because it didn't have the annoying lag due to all the strange T9 hooks integrated on HTC's WinMo build. Just because everyone else has failed seriously hard at making an on-screen virtual keyboard doesn't mean that someone can't actually do it *right* for once.

5. Just straight up wrong. iPhone OS has had full stereo A2DP since OS 3.0. Another major complaint tackled. Oh, and I discovered that this actually works without tweaking, unlike on my Touch Pro. 6. Jailbreak, then Unlock, and go to T-Mobile. Sucks to not have 3G, but then again, on AT&T you can't have 3G with the Nexus One. I blame T-Mobile for their non-standard, after-the-fact 3G band addition.

LyX is my de facto lazy LaTeX crutch, for when I don't feel like really writing straight LaTeX, but need the same feel and ease of use. Plus, seeing formulas actually semi-typeset is marvelous. That said, I'm amazed that anyone would honestly use it to take notes. First of all, you're not exactly creating something that's immediately accessible or lends itself to organization in any fashion. How are/how do people organize this? I've tried everything and I eventually just settled on a tablet. Freshman year I took all my notes on a Samsung Q1 ultra; admittedly this was great since battery life was upwards of 7 hours, but having a passive digitizer killed me. Now, I do all my notes on a Latitude XT in OneNote. I honestly wish there was a *nix equivalent that worked half as well, because I'd use it, but OneNote is just about the biggest killer app ever for notes and tablets. It's an amazing end-all note taking solution that not only recognizes and searches, but makes it easy to organize and backup. I can now access any of my notes going back many years, on the fly, and access them from multiple computers (tablet and desktop). I routinely get wows from professors and other students that are amazed they can't do the same. I honestly wonder some days why people run around scrawling notes on dead trees with what amounts to a rock that leaves marks. Why drop 2k on a macbook you admittedly can't take notes on when you could buy a tablet?
