The first thing I need to say, right off the bat: Chinese users will not buy your software. Period. That does not mean that there is no money to be made, it simply means that they will not pay for your software license.

While injecting the dependency appeared to make the classes more tightly coupled, it simply revealed the coupling that already existed. A was already tightly coupled to B and B to C. When we tried to inject the dependency, we made that coupling more explicit and easier to remove.

Programming is a deceptively damaging field to be in, partly because it doesn't seem like you're doing much, and also because of the attitude many programmers have toward their body. You should care about keeping yourself healthy because, when your body is in good shape, that removes "friction" from your mental capacity so that it can focus on important things rather than annoying little problems with your physical wellness.

The problem isn't that Git is to hard, it's that smart developers are impatient and have exactly zero tolerance for unexpected behavior in their tools.

Apple’s App Store was a constant source of stress in the development process. Every time another story of Apple randomly booting an app from the store came out, the whole team quaked. The idea that we could do all this work and then Apple could deny the app, or even keep it in limbo forever, made us second- or third-guess every design decision. “Will this pixel hurt our chances of getting accepted?”

Well, today computers really only have one kind of storage, and it is usually some sort of disk, the operating system and the virtual memory management hardware has converted the RAM to a cache for the disk storage.

All browsers that support the CSS text-shadow and box-shadow properties also support the new CSS3 RGBa syntax. Which means you can safely combine them today.
