This seems like an intentional misunderstanding for press attention. How do you get from "shipments of lithium-ion and lithium batteries on cargo aircraft" to banning laptops?

Use monkey patching in tests, never in production. Monkey patching is fragile, but in tests, who cares? If it breaks, you see why and you fix it. Tests don't have to be held to the same level of reliability as production code.

I would never use swizzling (the Objective-C equivalent) in production code, but I use it regularly in tests. I think that's the relevant distinction.

Amen. Same goes for Objective-C: dependency injection simply isn't needed when you can swizzle out any method (including +alloc) in tests.

It is illegal for taxi drivers to refuse your fare depending on your destination. If their "Off Duty" light is not lit, just get in, then say your destination. If they protest, say you'll call 311 (and start taking a picture of their licens

That didn't work out too well for the newspapers, did it? Newspapers got away with it for so long because they held a monopoly on information distribution.

Many third-world countries already have this—usually fleets of young men on motorcycles that will deliver whatever you need.

Brilliant. I've longed for something like this.

They control their cash and assets. This indicates that investors believe Zynga will use up their assets without producing any profit from them—that is, their RoE is negative.

Why would I bother investing money at all then? You can expect an annual return of around 7% on the stock market, subtract 4% wealth tax and 2% inflation and you're left with nothing in real terms. Everyone (even the super-wealthy) would sp

$50 is equal to about 20 minutes-60 minutes of your time. Chocolat has easily saved me that much frustration and time. So it's worth it for me.

Apple will never allow a JIT Javascript engine on any app except their own, for security reasons. (App Store apps can't allocate pages with the executable bit set, which is a good idea really.)

Who has a "best friend" who is a fitness trainer at age 17? He doesn't seem to be US-based (mentions IB, and English is his second language) so not paying (as much) tax must help things. It sounds like SEO linkbait/blogspam type stuff to me

Address Book has always been a C API, not an Objective-C API, for legacy reasons. I suspect that had a lot to do with it.

Palo Alto has plenty of trees—and not coincidentally, I believe its per capita income is even higher than Mountain View's.

It'll be interesting to see what happens when Apple's TV is released. I suspect the resale value of all other televisions will crater as everyone tries to sell their old TV (and potential used purchasers instead purchase new Apple TVs).

Too late. Single-family homeowners now control the zoning boards in Silicon Valley, and they're generally opposed to building new apartments or mass transit. New infrastructure is far too expensive these days anyway. I suspect this is one f

I too thought of a forward braking light. When self-driving cars become common enough, people would learn to interpret it.

All this VC money comes from pension funds, university endowments, and other large institutional investors that are looking for a return on investment that is higher than regular public equities. When the crash comes, pensions and endowment

Theft is a real problem for these stores. And theft makes me angry. I'm willing to trade being recorded in public for a low-crime society.

Try LinkShare, which will let you create arbitrary tracking code URLs that track sales. It's a bit messy since they're affiliate URLs, but you can figure it out.

OK, so let's say you spend $10k of developer time (about 1 month at current salary rates) to optimize your code to save the environment. You must be saving less than $10k in electricity over the next couple years (otherwise you would have d

Security cameras are everywhere. And soon every car will have a cell radio. What would be neat is a cross-linked solution: when a window is broken, instead of a noisy useless car alarm, inform the police immediately with a geographic locati

Wow, the vehicle theft rate is almost 5 times higher in SF than NY: http://newyork.areaconnect.com/crime/compare.htm?c1=san+fran... Of course this was burglary or theft, not vehicle theft. But I wonder what makes for such an extreme diffe
