They don't have nearly as much to offer if they can't do launches quickly. I'm sure they would make that a feature of their offering.

They can carry about 110kg to LEO, compared to the Falcon 9's 13150kg. That's 0.84% of the payload capacity. A launch is estimated to cost $4 900 000, compared to the Falcon 9's $61 200 000. That's 8.01%. That means cost per mass to orbit is nearly an order of magnitude worse.
Yes, this is a really small rocket. If you are a government or some other entity that needs to put something small in orbit right away, the USD$5 Million price might not deter you, even though you could potentially launch a lot of small satellites on a Falcon 9 for less.
And it's a missile affordable by most small countries, if your payload can handle the re-entry on its own. Uh-oh.
John Gruber On Third-party Apple Watch Apps: They Suck and Are Really Slow 138
An anonymous reader writes During this week's episode of John Gruber's podcast, The Talk Show, Gruber sat down with Joanna Stern of the Wall Street Journal to talk all things Apple Watch. About two hours and 9 minutes into the podcast, both Gruber and Stern began lamenting the poor performance they saw with third-party Apple Watch apps. 'It makes me question whether there should be third party apps for it at all yet,' Gruber noted. The pair also took umbrage with what they perceived to be a poor design choice for the Apple Watch app screen, with both noting that the app icons were far too small to be practical.
Gyrocopter Pilot Appears In Court; Judge Bans Him From D.C. 271
mpicpp writes The Florida mail carrier accused of landing a gyrocopter outside the U.S. Capitol on Wednesday was charged in federal court Thursday and has been barred from returning to the District of Columbia or flying any aircraft, officials said. Douglas Hughes, 61, was charged with violating aircraft registration requirements, a felony, and violating national defense airspace, a misdemeanor. If convicted, he could be sentenced to up to three years in prison for the felony and one year in prison for the airspace violation. U.S. Magistrate Judge Deborah A. Robinson also barred Hughes from the District of Columbia, except for court appearances, and said he must stay away from the Capitol, White House and nearby areas while he is there. He will also have to hand over his passport.
Microsoft's Role As Accuser In the Antitrust Suit Against Google 192
HughPickens.com writes Danny Hakim reports at the NYT that as European antitrust regulators formally accuse Google of abusing its dominance, Microsoft is relishing playing a behind-the-scenes role of scold instead of victim. Microsoft has founded or funded a cottage industry of splinter groups to go after Google. The most prominent, the Initiative for a Competitive Online Marketplace, or Icomp, has waged a relentless public relations campaign promoting grievances against Google. It conducted a study that suggested changes made by Google to appease regulators were largely window dressing. "Microsoft is doing its best to create problems for Google," says Manfred Weber, the chairman of the European People's Party, the center-right party that is the largest voting bloc in the European Parliament. "It's interesting. Ten years ago Microsoft was a big and strong company. Now they are the underdog."
According to Hakim, Microsoft and Google are the Cain and Abel of American technology, locked in the kind of struggle that often takes place when a new giant threatens an older one. Microsoft was frustrated after American regulators at the Federal Trade Commission didn't act on a similar antitrust investigation against Google in 2013, calling it a "missed opportunity." It has taken the fight to the state level, along with a number of other opponents of Google. Microsoft alleges that Google's anti-competitive practices include stopping Bing from indexing content on Google-owned YouTube; blocking Microsoft Windows smartphones from "operating properly" with YouTube; blocking access to content owned by book publishers; and limiting the flow of ad campaign information back to advertisers, making it more expensive to run ads with rivals. "Over the past year, a growing number of advertisers, publishers, and consumers have expressed to us their concerns about the search market in Europe," says Brad Smith, Microsoft's general counsel. "They've urged us to share our knowledge of the search market with competition officials."

Microminiature accelerometers are really cheap and very very light, and you don't have to wait for them to spin up or deal with their mechanical issues. I doubt you will see a gyro used as a sensor any longer.
Similarly, computers make good active stabilization possible and steering your engine to stabilize is a lot lighter than having to add a big rotating mass.

When you last flew a jet somewhere, why wasn't it a seaplane? Surely such things would be an easier problem to solve than building airports.
Short of giving you the starter course in rocket engineering, I can only say no, it's not easier.

The booster can indeed make it back uprange to Kennedy Space Center, and they've leased a landing pad for it there. Besides the turn-around burn, they tilt the booster against the airstream and let aerodynamics push it back uprange during that 78 mile descent.

If there's one thing they should work on, it's not thrusters but having the capability to throttle to hover. That would potentially change the entire low approach. It is complicated by the fact that engine performance goes nonlinear in the low range.

A video from the barge is now online here. If you step through the final frames, you can see that the camera mount ends up knocked over and pointing at the ocean, but the lens and its cover are unbroken and all we see flying appear to be small debris. So not a really high-pressure event.

While encrypted psuedo random is a more complex function, it is still PSUEDO random not real random. Future output is a function (now a more complex function) of past output.
Not only the secret key must be kept secret, but the seed (either current or original) must be kept secret.
If the attacker knows the algorithm, which they might, then they may be able to analyze the output. If they know the seed, then the problem becomes one of a known-plaintext attack upon the encryption algorithm. If they know the encryption key, it becomes a matter of finding a seed that generates some known pre-encryption output of the psuedo random algorithm.
We could go back and forth about the practicality and difficulty of such attacks. But switching from psuedo to true random eliminates that entire discussion.
Your $10 webcam + lens cap is a good idea BTW. Or other similar ideas of using various sensors to capture random noise. Just hope the noise really is random. Also, a $10 webcam without a lens cap, pointed at something, like a busy street, might also be a source of randomness in the pixel data.
