There's demuxing and there's decoding. Demuxing can easily be done in software where it can fail gracefully. Decoding is computationally expensive and can't be done in software. On many devices, software decoders are too slow

When given the option to either abort the process or put hardware into an unrecoverable state and requiring a reboot, you leave the assert in for production.

> On top of that, the hw decoders don't even give the profile and level they support, so you have to guess them. We actually put together a codec tester that runs right before the first time a user plays a video precisely because of

"Since your average Android application does not have sufficient permission to access /dev/* entries on your system, you must use a proxy called the mediaserver in order to communicate with HW codecs." This is incorrect.

My favorite is "5KB". The prefix for kilo- is a lowercase 'k'. Uppercase 'K' is Kelvin. I don't even know how to conceptualize a Kelvin-Byte.

I think just like alecdibble, you're missing the point. sudonim isn't commenting on the ethics or legality of Uber's strategy, but putting him/herself in the Uber CEO's shoes and imagining the stress associated with executing on a strategy

You're absolutely right. Like I said, it's a good exercise. A business plan that works on paper is, roughly speaking, a necessary but insufficient condition for success. So as such, you shouldn't bring it to a meeting with an investor or

Color was pictures plus location, that's true. Instagram is also just pictures and filters, which is equally dumb but turned out pretty well from an investor's point of view. However, you make a good point. Neither Color nor Instagram wer

I mean, I'm not defending Color. It was a terrible app and an even more terrible business. Sequoia invested in the team because they liked them. They gave a bag of money to people they thought could make good use of it, and it didn't pan

Backbone is one of those libraries/frameworks/whatever that avoids magic. It's just a pile of reusable parts that make building big javascript applications easier. One can't say the same about, say, Rails. There's a lot of magic in Rails

Do people really use the "11 days" thing in defense of javascript? I get that it was rushed into production, and all things considered, that was probably the appropriate thing to do given its intended use at the time. But it doesn't matte

I second this. Javascript is a dumpster-fire of a language, as is PHP. If I could use anything other than javascript for scripting in the browser, I would, but I can't. So I use it. I can use things other than php on the server, so I do
