jon_hendry··on Ask HN: tips for working with Mac OS X without using the mouse? (RSI)
I had to disable pinch-to-scale with mine. All too often I'd be reading something in the Xcode documentation window, and a slight, inadvertent movement of my fingers would cause the text to get really big or really small.
jon_hendry··on Ask HN: tips for working with Mac OS X without using the mouse? (RSI)
I find myself supporing my fingers over my Magic Trackpad, which is tiring. At the very least I have to raise all my fingers except the ones I want to use in a gesture.

My other preferred device is a thumb-ball trackball. I have a logitech trackman, and the discontinued one from Microsoft. I find those much more comfortable, if a bit problematic for high precision. I just wish I could get a bluetooth one.

jon_hendry··on Ask HN: Is USA that bad when it comes to health insurance, etc?
Yes. But the more important thing is the non-negligible possibility of losing coverage completely due to job loss.
jon_hendry··on Scribd.com Comes to the Dark Side
Except people post whole books to Scribed, while on YouTube, you can't post a whole ripped DVD in one post.
jon_hendry··on 77% of the population have symptoms of personality disorder?
Sigh.

Everyone has one or two symptoms, a little, occasionally. To actually have a personality disorder you have to have lots of symptoms, often, to a severity that it causes problems in your life.

Lots of people have occasional headaches. You could also say those people have symptoms of a brain tumor. But that would be stupid because they lack many other symptoms of a brain tumor.

"I doubt this will do much - people have found out that you can download whatever tv show you want online, why should they pay for it on iTunes?"

Simplicity. No need to deal with format issues, or un-seeded torrents, or corrupt files, or varying quality.

jon_hendry··on Ray Kurzweil Responds to "Ray Kurzweil does not understand the brain"
It basically comes down to this: Kurzweil's paralyzing fear of death demands that the human brain be simulated soon, before he dies, so that his consciousness can be preserved in silicon.

Add in Moore's Law and an underestimate of the complexity of the brain, and stir.

Exponential growth in IT is great, until you run into a problem that is exponentially harder than you originally estimated.

Also, you're born with a lot of neurons that are then pruned off during childhood. Newborns have more neurons than adults. Adults have more glial cells.

"Also, it's a fracking mobile phone you are holding in the palm of your hand and you want it to be as powerful as a desktop experience? Reality check!"

This would be more persuasive if there weren't non-Flash video and non-Flash games for comparison that don't have the same problems.

But how do you connect it to the cup of no tea?
jon_hendry··on Apple’s App Store Director Sells His Own Fart Apps
"How about the fact that the same guy institutes policies that ban huge swaths of apps (including anything not written in Objective-C)?"

I doubt the ObjC/C++/C requirement was his call. He may be in charge of enforcing it, but something like that would have come from higher up.

jon_hendry··on You’re a developer, so why do you work for someone else?
Maybe get checked for sleep apnea? If you have it, you repeatedly stop breathing during the night. It isn't long enough to kill you, but it's long enough to lift you out of deep sleep into shallower sleep, or keep you from entering the deep sleep states.

And they never stopped doing surface application of DDT.

"And when and how did it resurrect itself?"

Immigration and tourism from countries with less vaccination.

Combined with reduced vaccination in the US.

jon_hendry··on You’re a developer, so why do you work for someone else?
"No, seriously, a @#$% goldmine! Never in modern history has it been so easy to create something from scratch, with little or no capital and a marketing model that is limited only by your imagination."

ie, high supply. Lots of competition.

It's getting to be like writing novels. Lots of people do it. The barriers to entry are low. But few can make a living at it.

jon_hendry··on Editorial: Waiter, there's a Nazi theme in my Android Market
"Yes it would be illegal in Germany, but here in the US we do have freedom of speech. From flag burning, to KKK rallys and in this case Nazi insignia are all examples of free speech, and protected by the Constitution."

The 1st amendment is about Congress, not about what retailers allow into their stores for sale.

jon_hendry··on Kindle vs. iPad Displays: Up close and personal
The contrast of e-ink, in my experience, improves with brighter lighting. Outdoors in sunlight it's quite good. Also, I find a bright white CFLs to give better contrast than similarly-bright incandescents.

Your mileage may vary, of course.

jon_hendry··on Let's make a shit JavaScript interpreter Part one.
"The article's goals are noble, but in this one spot, we seem to be flirting with flaunting one's ignorance and thinking it wit."

There are plenty of valid reasons to not be a member of the lisp cult.

"Anyhow, here's a slicker way of doing it."

Which entirely misses the point of the article, which is to DIY, not rely on some tool to generate it for him.

jon_hendry··on The amazing story of illegal arms dealer Viktor Bout (2003)
Check out the archives of the blog Yorkish Ranter. He ran a Bout-tracker, that scanned the air flight databases of places like Sharjah, to track the flights of Bout-connected shady air transport companies.

Very interesting.

jon_hendry··on Ask HN: Why do no other laptop manufacturers get it?
They certainly go out of their way to NOT tell you the resolution of their screens. Nowhere on that page does it tell the resolution. Click to configure one, and it still doesn't say.

At best they say "HD", but that's meaningless, as there are several HD resolutions. They give the screen size, but that's meaningless.

WTF? Why do PC vendors do that? Either they don't say it all, or they use some obscure acronym. Would it kill them to just put in the frigging numbers?

jon_hendry··on Mobile Multitasking
Android also has the MemoryFile class, which can be set "purgeable".

"MemoryFile is a wrapper for the Linux ashmem driver. MemoryFiles are backed by shared memory, which can be optionally set to be purgeable. Purgeable files may have their contents reclaimed by the kernel in low memory conditions (only if allowPurging is set to true). After a file is purged, attempts to read or write the file will cause an IOException to be thrown."
