Yes, but the towers are broadcasting signals that are orders of magnitude more powerful to ground receivers than the gps satellites. If Lightspeed was a satellite phone system (so if it was another satellite system producing the crosstalk), it would not interfere even if the frequencies were directly adjacent.

In 1989 the Loma Prieta quake took out the upper deck of the Bay Bridge, but left BART's Transbay Tube undamaged. No one died on any of BART's elevated tracks either (I don't recall any stories of major damage either). The structures needed for HSR are not much different.

If we actually had $100B to spend on California transportation infrastructure we should

1) Improve the 7(!) airports between the Bay Area and LA.
2) Improve commuter rail as the previous poster suggested. Grade separated BART down the Caltrain tracks, BART to San Jose, Geary Ave Subway (and those are just the Bay Area projects).

The flights are quite fast at roughly an hour in the air, and there are few weather delays. The local rail projects would vastly improve the commutes of many and make it enjoyable to be car-free in may parts of the Bay Area.

Agreed - where are the brownouts in CA? I live here, read the newspaper, and I don't hear about them.

We've had rolling blackouts
1) in 2001 due to Enron
and
2) when it gets > 100 F in the summer across the entire state - so one or two afternoons every 3-5 years or so.

Agreed, writing himself into his own novel was *weak*. I also thought he borrowed far too heavily from Harry Potter in the last one.
The first 3 were great, I really liked the 5th as well (4th was good, could have been its own novel). Way downhill on the 6th and 7th.

Really? I have not. I have the latest/greatest Mac Book Pro with i7, etc. I've gotten a *lot* of the "there may be a performance problem" message and finally turned my settings way down. I've been hugely disappointed considering this was supposed to be a badass laptop playing a "not quite hardcore" game. I remember playing the original Starcraft on a Pentium Pro running NT4 (ah DirectX 2, is there any OS you weren't on?)

Data Storage

"Limited Edition" SSD Has Fastest Storage Speed 122

Vigile writes "The idea of having a 'Limited Edition' solid state drive might seem counter-intuitive, but regardless of the naming, the new OCZ Vertex LE is based on the new Sandforce SSD controller that promises significant increases in performance, along with improved ability to detect and correct errors in the data stored in flash. While the initial Sandforce drive was called the 'Vertex 2 Pro' and included a super-capacitor for data integrity, the Vertex LE drops that feature to improve cost efficiency. In PC Perspectives's performance tests, the drive was able to best the Intel X25-M line in file creation and copying duties, had minimal fragmentation or slow-down effects, and was very competitive in IOs per second as well. It seems that current SSD manufacturers are all targeting Intel and the new Sandforce controller is likely the first to be up to the challenge."

I think you'll be surprised and that it will.

I upgrated my old steel hardtail mountain bike into an ebike becuase I have a ~400 vertical foot climb from the train station to work.

I bought the Phoenix motor kit by Crystalyte (http://www.electricrider.com/crystalyte/phoenix.htm) and swapped out the acid batteries for a Lithium Ferrous Polymer at a very reasonable price (thank you Lau Chen of Hong Kong).

The result is a bike with almost 2000 watts max power (48V x 40A = 1920W) with 10Ahr of total juice. The practical range is about 10 miles at a speed of 30 MPH (I have a motor wound for slightly more torque).

My time up the hill basically beats driving (surface streets, not freeway). An interesting thing happens when you go as fast as cars - they see you better, you can get out of the way better and you take fewer stupid risks. For example, you are less likely to run a stop sign if you can re-accelerate easily. Also, if you're not pedaling hard you have more energy to focus on what's around you. It becomes more like riding a motorcycle.

I love my e-bike - once people see
1) How versatile they are (go anywhere a car can go and slightly more)
2) How cheap they are (fuel cost approaches zero even charging at home)
3) How normal you look on them (it's just a bike)
and most importantly
4) How lazy you can be on them (you don't sweat at all)

You will see much better adoption in the short range commute, even in the US.

Facebook Master Password Was "Chuck Norris" 319

I Don't Believe in Imaginary Property writes "A Facebook employee has given a tell-all interview with some very interesting things about Facebook's internals. Especially interesting are all the things relating to Facebook privacy. Basically, you don't have any. Nearly everything you've ever done on the site is recorded into a database. While they fire employees for snooping, more than a few have done it. There's an internal system to let them log into anyone's profile, though they have to be able to defend their reason for doing so. And they used to have a master password that could log into any Facebook profile: 'Chuck Norris.' Bruce Schneier might be jealous of that one."
