barefoot··on Flying Cars Get OK From Department of Transportation
In order to use the Vehicle as a plane you still need to have at least a sport pilot license - which is kind of like a restricted pilots license. In order to get your sport license you need to learn, and are tested on, the airspace limitations that apply to all pilots. Those rules effectively stipulate* that you can't fly over a large portion of DC, including the White House, and should not fly or loiter anywhere near power plants, prisons, etc...

If you break those rules, even innocently, the FAA can come down hard on you by revoking your license and fining you thousands of dollars. Depending on how sensitive the area is and how suspicious you appear they can send other aircraft to your location and (in the case of the DC FRZ) potentially shoot you down. Once you've been indoctrinated into the system you learn to be extremely aware of where you are, what is nearby, and to stay away from sensitive areas.

*There are ways, at least for private pilots, to legally fly over a lot of restricted areas but it's much easier to just fly around them or not bother.

(pilot) Probably wouldn't be significant. If you go walk around at an airfield you'll notice all types of similar imperfections on airplanes and they still fly perfectly fine and are classified as airworthy.

There are a few exceptions (propeller, cracks, etc...) but planes are a lot more forgiving to surface deformities than you would imagine.

barefoot··on Augmented Reality 3d Video on iPad with Kinect
Looks like you and I have toyed with the same idea (Kinect controlled lighting). I was shocked by how easy it was to put together and how effective it was. Probably not an easy thing to commercialize though ("yeah, just embed these sensors in your walls and replace all of your light switches...").

I put together a very basic Kinect controlled lighting app for fun using ManagedNite:

barefoot··on How To Safely Store A Password
Agreed, but an important part of the article was that even public salted md5 passwords are ineffective.
barefoot··on How To Safely Store A Password
Hashing passwords on the client indicates that the salt is available to the client. In the event of a database compromise it's guaranteed then that the attacker will have the salt and be able to crack your passwords.

If the salt is stored on the server, in a login.php script for example, and there is (just) a database compromise then an attacker will be at a disadvantage because they will need to figure out the salt first before cracking any of the passwords.

In fact, this is something being ignored here quite a bit. A number of potential attacks only lead to the database - or part of it - being exposed. If you have a large enough salt stored in your unaffected code base then an attacker is going to have a hard time.

barefoot··on Volkswagen Shows Off Self-Driving Auto Pilot Technology For Cars
These are the types of steps I'm guessing we'll see over the next few years towards driverless cars. It's not difficult to imagine these incremental changes becoming more and more frequent as companies compete in this space.

One thing that strikes me as interesting is the possibility for software upgrades in your car to enable more (automated driving) features. Once all of the hardware is in place it seems like a natural progression.

Who's to say that the hardware won't plateau well ahead of social norms, legislation, and software and that we won't end up with an awkward period of automated-ready cars?

barefoot··on Being Frugal Makes You A Loser
Which study was that? I've heard the same thing mentioned several times but never seen the actual source.
barefoot··on Being Frugal Makes You A Loser
I think he's (doing a bad job of) saying that you should buy quality items to improve your day to day living and not fall into the trap of buying cheap items and then artificially limiting your earning power accordingly.

barefoot··on Bye Bye Skype, Top 3 Free Replacements
Some companies are certainly less (or more) evil when common societal norms and mores are used as a yardstick. Look at Xe (Blackwater) for example:

http://www.google.com/search?q=blackwater+allegations

Microsoft (and most tech companies) are not very evil in comparison so I think it's very possible to make a quick heuristic determination about how evil two companies are.

Now, take away Xe and compare Microsoft, Google, IBM, and Apple for example. Certainly one is most evil and one is the least evil.

The problem I think you're pointing out is that they are probably very close to each other on the good-evil spectrum. Our moral irises have just opened all the way because we sit in comfortable padded chairs and wiggle our fingers over a plastic box all day to make a nice living.

barefoot··on MySQL Text vs. Varchar Performance
Good advice. "Explain" in this case wouldn't be enough to work out what's going on, however. In both the TEXT and VARCHAR cases he expected the queries to be using temporary tables so the output from mysql explain (both showing the use of temporary tables but not the storage medium such as disk or memory) would not have helped.
barefoot··on Biggest BitTorrent Downloading Case in U.S. History Targets 23,000 Defendants
The "This Week in Law" podcast has touched on this issue a few times:

Although I can't remember the specific episodes.

barefoot··on Hacking The Status Game
Also known as kinesthetic anchoring, the bread and butter of basic NLP. It's pretty controversial like the rest of the material and is probably utterly ineffective.

Autocorrect on iOS, sorry.
barefoot··on FBI seized PokerStars.com, FullTiltPoker.com, UB.com,... domain names
They are using a TLD (top level domain name) operated by a US company (Verizon).

The government hasn't gone out of it's jurisdiction, technically speaking.

barefoot··on Where can I get large datasets open to the public?
How many of these allow me to create for-profit websites with them?
barefoot··on How to find startup ideas that make money
This is a very subtle distinction.

You say "...it's suggesting that rather than searching for a need you want solved and framing it in terms of a realistic goal and whittling it down to a compelling product, you should be identifying someone else's need and building that product."

But "framing it in terms of a realistic goal" and "whittling it down to a compelling product" both sound like code to me for "making something that other people want / need".

One key part of customer development is that creating a new market (for something that you exclusively need) is extremely expensive. You have to educate your customers on why they need your product and push against a massive amount of resistance.

I think it's pragmatic then to accept that working with an existing market in some shape or form is inevitable. So, why not embrace it? I think that's the market-driven approach.

You can still come up with novel and fun ideas that you own, but ground them in an existing market that you've researched.

barefoot··on Massive SQL injection attack making the rounds—694K URLs so far
It sounds more like cross site scripting to me than SQL injection. In SQL injection you try to coax a database engine into performing a previously unintended action by carefully crafting content that is part of a query.

If this attack works by storing the data in the original (intended) field and just happens to bypass the JavaScript filters then it's XSS and not injection.

barefoot··on How to damage your brand in one smooth shot - Way to GoDaddy
Right, I find it difficult to believe that any of this was uncalculated (does that make me a high-mach?)

They appear to target the bottom 90% who needs a domain name. And, they very wisely get name recognition with non tech savvy business owners who often have the ultimate decision in which registrar to use.

Look at it from the vantage of a typical conservative small business owner here in America. Slaughtering a beautiful and rare animal is not deaf-ear branding - it's shrewd marketing. GoDaddy is not afraid to kill to solve problems. The association is powerful and on target.

barefoot··on Apple’s boring hardware updates
How about a display on the back? That way there would be (nearly) no wrong way to hold your phone.
barefoot··on Apple’s boring hardware updates
I know a few people who have the money to buy an iPhone 4 that will not simply because of the "consumer reports" iPhone antenna review. It's nonsensical for sure but I wouldn't be surprised if it would help apple to put the issue to bed for good.
barefoot··on What life lessons are unintuitive or go against common sense or wisdom?
I agree completely.

It's very frustrating to deal with people who apply NLP or lay-CBT on a regular basis. Especially when you are trying to have a rational conversation and they are wasting time trying to "learn about sub-modalities" or apply auditory anchors to things like acceptance or rejectance.

One person I work with occasionally very clearly thinks of himself as talented in mind control by applying these things. However, from the outside it's very apparent that they have simply poisoned his perspective to make him believe he is being successful.

In short, I wish people would stop wasting time propagating pseudoscience.

barefoot··on Color
Exactly: provided that $350,000 was a decent price (which doesn't seem too unreasonable) and the fair value does not decline they now have a $350,000 intangible asset on their balance sheet that will not likely decline in value.

You can't say the same for a similar amount of put into high end office furniture, for example.

barefoot··on Neil Gaiman: Why defend freedom of icky speech?
Agreed. I'm a fairly strong minded atheist and I find creationism offensive. At the same time I would defend to the death the right for creationists to have free speech.
barefoot··on Show HN: We made a web-based cash register
My only reservation after looking at this. You could imagine the "POS" acronym changing meaning very quickly in the event of connection failure.

That said, maybe they could eventually integrate gears or some other type of offline storage.

barefoot··on Make something people need
"if they want it they need it"

Disagree. I want a new 2G iPad, but my 1G iPad works well enough and I don't need it. I would like one but I'm not going to express that desire with cash.

I see where you're going but I think it's an important distinction to make, especially with consumers. It's easy to take a sharp rational mindset and project it onto the fish in the stream... but that may not be the best model for predicting how they think about your products.
