App Cubby Blog – The Sparrow Problem

Given the incredible progress and innovation we’ve seen in mobile apps over the past few years, I’m not sure we’re any worse off at a macro-economic level, but things have definitely changed and Sparrow is the proverbial canary in the coal mine. The age of selling software to users at a fixed, one-time price is coming to an end. It’s just not sustainable at the absurdly low price points users have come to expect. Sure, independent developers may scrap it out one app at a time, and some may even do quite well and be the exception to the rule, but I don’t think Sparrow would have sold-out if the team — and their investors — believed they could build a substantially profitable company on their own. The gold rush is well and truly over.

via App Cubby Blog – The Sparrow Problem. There is a real problem going to occur with regards to the App Store and desktop/mobile software in general if pure software businesses aren’t able to sustain themselves in the long-term. Apple can get away selling software for cheap thanks to hardware profits, what is the option for software only firms?

DataGenetics – The Two Egg Problem

You are given two eggs, and access to a 100-storey building. Both eggs are identical. The aim is to find out the highest floor from which an egg will not break when dropped out of a window from that floor. If an egg is dropped and does not break, it is undamaged and can be dropped again. However, once an egg is broken, that’s it for that egg.

If an egg breaks when dropped from floor n, then it would also have broken from any floor above that. If an egg survives a fall, then it will survive any fall shorter than that.

The question is: What strategy should you adopt to minimize the number egg drops it takes to find the solution?. (And what is the worst case for the number of drops it will take?)

There are no tricks, gotchas or other devious ruses. Don’t rat-hole with issues related to terminal velocity, potential energy or wind resistance. This is a math puzzle plain and simple.

Think about the puzzle for a few minutes, and then read on.

The Word of Notch – On Patents

But there is no way in hell you can convince me that it’s beneficial for society to not share ideas. Ideas are free. They improve on old things, make them better, and this results in all of society being better. Sharing ideas is how we improve.

via The Word of Notch – On Patents. Notch (the guy who started Minecraft) has a really good piece on why patents are a bad idea. My opinion on patents has slowly changed from thinking that just software and business process patents to getting more convinced that patents in general are a bad idea.
