Almost all router bandwidth management is shit.
Bandwidth management schemes currently used by everything you mention are all base on rate limiting packet delivery based on some mythical QoS value, and they ignore the actual problem that the people who are using these things are attempting (and failing) to address.
The problem is that the point of a border routers is to hook a slower border uplink to a faster interior connection; on the other end of the slower uplink, you have a faster ISP data rate. In other words, you have a gigabit network in your house, and the ISP has a gigabit network at their DSLAM, but your DSL line sure as hell is *NOT* a gigabit link.
What that means is that software that attempts to "shape" packets ignores an upstream-downloads or a downstream-uploads ability to overwhelm the available packet buffers on the high speed side of the link when communicating to the low speed side of the link.
So you can start streaming a video down, and then start an FTP transfer, and your upstream router at the ISP is going to have its buffers full of untransmitted FTP download packets worth of data, instead of your streaming video data, and it doesn't matter how bitchy you are about letting those upstream FTP packets through your router on your downstream side of the link, it's not going to matter to the video stream, since all of the upstream router buffers that you want used for your video are already full of FTP data that you don't want to receive yet.
The correct thing to do is to have your border router lie about available TCP window size to the router on the other end, so that all intermediate routers between that router and the system transmitting the FTP packets in the first place also lie about how full the window is, and the intermediate routers don't end up with full input packet buffers with nowhere to send them in the first place.
Does your border router do this? No? Then your QoS software and AltQ and other "packet shaping" software is shit. Your upstream routers high speed input buffers are going to end up packed full of packets you want less, and you will be receiver live-locked and the packets that you *do* want won't get through to you because of that.
You can either believe this, or you can get a shitty router and not get the performance you expect as the QoS software fails to work.
Then you can read the Jeffrey Mogul paper from DEC Western Research Labs from 1997 here: http://citeseerx.ist.psu.edu/v...
BTW: I also highly recommend the Peter Druschel/Guarav Banga paper from Rice University in 1996 on Lazy Receiver Processing, since most servers are still screwed by data buss bandwidth when it comes to getting more packets than they can deal with, either as a DOS technique against the server, or because they are simply overloaded. Most ethernet firmware is also shit unless it's been written to not transfer data unless you tell it it's OK, separately from the actual interrupt acknowledgement. If you're interested, that paper's here: http://citeseerx.ist.psu.edu/v... and I expect that we will be discussing that problem in 2024 when someone decides it's actually a problem for them.
Nothing you say says that Mr Saverin has gotten away from his US tax liability. Only by renouncing citizenship can one end the tax liability, and even that continues for some years (10 I think) after the renouncement.
He did renounce it. And he renounced it before the IPO. So his liability is for what he owed before he renounced it, which is
How many homeless volunteers took off with the camera and sold it to buy booze?
I think there's a more important question... how many mountain lions, gazelles, and other animals took off with the Harmless Radio Collars(tm) that Marlon Perkins had Jim Fowler attach to them while filming Mutual of Omaha's "Wild Kingdom"?

Once thing they should look at is a city within a single mega-structure.
Why should they build an Arcology, when there are already two in progress:
Masdar City in Abu Dhabi: http://en.wikipedia.org/wiki/M...
Arcosanti North of Phoenix Arizona: http://en.wikipedia.org/wiki/A...
Yes, it is quite large, in relative terms. The city of Pittsburgh is only about 30,000 people, meaning the % of the population in those 2 centers alone accounts for roughly 1% of the population.
Off by a factor of over 10; as of 2012: population of 306,211. That's 0.08%, not 1%.
If those San Francisco residents who are "entrenched" had to pay for their taxes like new residents do, they would be paying 1.25% per year property taxes on the current value rather than the basis of when they bought the property.
That's a great reason to do what rental property owners do, and own a company that owns the property, instead of owning it themselves. Then if they ever want to sell it, they can sell if for a heck of a lot more money by selling the company, rather than selling the property, so the taxes don't go up any more than if you'd bought under prop 13 and never sold.
That's the McDonald's model (McDonald's happily admits to being a real estate company that happens to sell burgers and rents out properties their franchisees). It's also the same model that the Kaiser Family Trust uses.
The only way to fix the Bay Area housing crisis is to build more fucking housing.
One of the things that isn't talked about is the amount of empty office and residential apartments in the Bay Area. It's actually worth more money to price them out of the range that people are willing to pay, and then take the "market rent you are not getting", and use it as a tax write-off. It's a common practice in China (Google "ghost cities"), and it's becoming more common in the Bay Area.
If you want to take a little trip on 101 between SF and SJ, it's easy to see a lot of empty buildings, and it's easy to see some of the mega-complexes that are going in in Redwood City and elsewhere, which are probably going to remain mostly empty as a tax write-off to balance out other income.
I was talking with a friend(another ex-Pittsburgher) and he reminded me that both Apple and Google have recently opened relatively large campuses in Pittsburgh.
150 employees in an old cookie factory for Google, and 100 employees for Apple retail is hardly "relatively large"...
They Bay Area is one of the few economically active places in the USA, that's why housing is expensive there.
If you want cheap housing, go to an economically dying area, like Detroit; or a place with no regulations such that chemicals leak into your house or explode in your face, like Texas.
Surely San Bruno would be more to one's liking...

Under a 2002 law it was made illegal to change the IMEI unless you're the manufacturer.
It's a Chuck Schumer http://en.wikipedia.org/wiki/C... bill that he introduces every couple of years, it gets thrown to the Judiciary committee, and then it dies in committee. Like clockwork. Here's the text of the current bill, which is presently dying in the Judiciary committee right now: http://thomas.loc.gov/cgi-bin/...:
The people who care about this are the people who traffic in stolen phones, and the people who want to buy a handset and use the same SIM in a different GSM phone, or who want to change the MEID on a new phone so that they don't have to re-up their Verizon contract once they are paying month-to-month for their CDMA phone. And the phone companies, that want you to have to re-up your contract to get a new phone. It's the same reason there's about zero incentive to update the OS in Android phones, since if they never update the OS, in order to get the new +0.0.1 version number bump, you have to get a new phone, and the manufacturer gets to sell another phone, and the phone company gets to lock you into a new 2 year contract every 18 months when the new shiny object becomes available.
Since it's a PITA to get a phone unlocked for international roaming, since it has to be listed by ID with the cell network in the country you are traveling to, and it can take many weeks to get them to actually unlock the thing, and do the registration, most times it's just easier to clone the IMEI to your old phone, and then either destroy the old phone, or do an IMEI swap. This is a common "repair/refurbish" technique, and you'll notice that it's allowed under the Schumer bill.
You might also see both NASDAQ OMX Group and TeleCommunication Systems Inc. campaign contributions, and you'll notice contributions from Facebook in 2012, the year the bill was introduced, when Facebook was going big into the mobile market. http://influenceexplorer.com/p...
Little bit of vested interest there.
Flying cars are technically possible.
Flying cars however are not desirable for everyday drivers: they have a hard enough time managing 2 dimensions, we don't need them to occupy a third. So unless they're fully automatic in flight mode (with manual control disabled), flying cars can only be flown by trained pilot.
Rename them "manned drones" and outsource the piloting to third world countries. Problem solved, since the FAA is OK with drones in U.S. airspace.
The only way for U.S. citizens to avoid this would be to go through a process to renounce their U.S. citizenship, which is not practical or desirable for most people.
Except for Eduardo Luiz Saverin, the Facebook co-founder who was basically paid by California and the federal government about $1.1B to move to Singapore. For him, it's was a pretty desirable and practical decision, given that the bite for short term capitol gains is treated as ordinary income by California for taxation purposes.
Who would have thought someone with a degree in economics from Harvard knew how to do money math? Uh... everybody? Hello?
Especially solar cells and carbon fiber windmills. All that nasty fossil silicon and fossil carbon from previous supernova. It's clearly a limited resource, in any case.
