I think the lesson here is that the Uber for X model was predicated on people being so unhappy with the incumbents that they would switch. Pre-Uber taxi services were criminally awful enterprises that deserved to get a beating. Local neighborhood businesses might be a bit low tech, but they know what they are doing (so there isn't much to disrupt).

An issue in SETI is the duty cycle problem. If a transmitter is cycling between targets (an isotropic beacon would require insane amounts of power), the receiver needs to be looking at the transmitter at the right time.

With inflatable structures, artificial G is possible to do with much less mass than you think. Using Bigelow Aerospace's BA330 as a proxy (60kg/cubic meter of habitable space), you would need between 5,000 to 20,000kg to build a 100m long passageway between 1 to 2m across on the interior. Inflatable structures are made from materials that handle tensile loads well (the hoop stress from pressurization in particular).
As an added bonus, the inflatable passageway, besides functioning as a tether, creates usable habitable space, so if one is clever, it is not strictly speaking deadweight mass.
Alex Tolley and I looked at this in detail while working on papers related to our "spacecoach" design pattern, you can find a good intro at https://medium.com/@brianmsf/traveling-to-mars-just-add-wate...

#1 Gawker did not out Peter Thiel. Peter Thiel outed Peter Thiel. Back when Friendster was a thing he had a public profile which featured him shirtless on a boat which clearly advertised his interest in handsome men. So on the scale from Closet Queen to Totes Obvious, he was more on the side of totes obvi. It was also the worst kept secret in San Francisco, particularly if you had any latin friends. So Owen Thomas was right in concluding that Thiel was already out when he ran his "Peter Thiel is totally gay" piece because it wasn't news to anybody.
#2 if Hulk Hogan is claiming injury and embarrassment from a sex tape, why did he make a sex tape? Yes, Gawker is muck raking trash (I just read it for the comments!), but they trade in such material. Unless I am missing something, Gawker didn't trick him into making a sex tape. Common sense would tell you that if you don't want your sex tape on the Internets, don't make a sex tape in the first place.

I enjoyed hours of fun and merriment going through security with it. Frankfurt in particular was a real bitch, as they called in the bomb squad to dismantle and inspect the phone. After they finally cleared me, one of the guards asked me "What is the purpose of this?" I responded "Because it's fun".
At least security in Newark had a sense of humor about it. They took photos of it for a book of all the weird shit that's gone through security there (I really hope they publish that someday).

I personally like to drive, especially on road trips, but I like the idea of a car that has much better reaction time that can correct if I do something stupid, or it sees something I can't (via vehicle to vehicle reporting).
Speaking of which, there will be many many opportunities to reduce impact severity. Example: a vehicle pulls out in front of you unexpectedly. If the car can react instantly where you'd take a fraction of a second, it can shed enough speed to reduce the severity of impact significantly (if not avoid it altogether). Reducing speed by 25%, will reduce the impact energy by almost half, so even small improvements will result in big differences in injuries and fatalities.

brianmcconnell | 10 years ago | on: Handcuffed to Uber
It bothers me that the terms are unnecessarily anti-employee. 90 days simply isn't enough time, especially when critical details related to the cap table and liquidation preferences are obfuscated. If they are not prepared to buy shares back at 409a value, they should allow an extended exercise window.
brianmcconnell | 10 years ago | on: Handcuffed to Uber
The moral of the story is to forward exercise options if you can. Basically what this means is you pay to exercise on your start date. If you quit or get pink slipped before the standard one year cliff, the company does a buyback. Otherwise, the shares vest as per your vesting schedule. You can potentially avoid a lot of the AMT nastiness this way, and start the clock on long-term gains treatment on day one.
That said, companies really should scrap the 90 day exercise window. Uber et al want to avoid employees selling shares on side markets. If they just allow them to hold onto their options for years, most will sit on them rather than feel rushed to sell. I know they want to retain talent, but they should be doing that via rewards versus punitive measures.
In any case, its worth it to spend a couple hundred bucks on a tax expert to figure out in advance how to handle options so you don't get burned by taxes on fictional gains.
brianmcconnell | 10 years ago | on: How the “what’s your current salary?” question hurts the gender pay gap
Treat this the same way you might go over a lease for office space. Let them make the initial offer (they have much better data about market rate and what they are willing to pay, you don't and may box yourself into a lowball position). Then take some time to figure out if it works, and take the comp discussion offline.
Keep the negotiation about compensation in writing. There are a million ways for an experienced negotiator to manipulate you in a live conversation. Break things down (salary, PTO, equity, 401k match, telework, other hard benefits), and figure out where they'll budge. And remember, it's not about being greedy, you'll be locking in your pay for 1-2 years, and you're doing your job of negotiating a good deal for you and your family. If someone doesn't respect that, that's a big red flag right there.

That said, I can see a couple of areas where solar will contribute.
While it will be very difficult to generate all of the power needed for an airliner via solar, there's no reason not to cover the aircraft in high efficiency (triple junction) solar cells. A large airliner will have a usable sky facing surface area of 1,000 square meters or so (rough estimate). Enough to generate a few hundred kilowatts of power. If the aircraft has hybrid gas/electric engines, that power can reduce the fuel burn a bit (even a small reduction is a big deal).
I can also see where a serial hybrid design could be workable (e.g. lots of fuel cells generating electric power that in turn drives electric fans). This would be attractive, especially in smaller planes, due to the potential to reduce the risk of mechanical failure.
If Thiel had really wanted to disrupt presidential elections, he could have thrown some money and social media connections behind Evan McMullin as a way of throwing a malotov cocktail into the race. It's his money, but if it were me I would not want to be associated with someone as vulgar as Trump.
