Games "MineAssemble is a tiny bootable Minecraft clone written partly in x86 assembly. I made it first and foremost because a university assignment required me to implement a game in assembly for a computer systems course. Because I had never implemented anything more complex than a 'Hello World' bootloader before, I decided I wanted to learn about writing my own kernel code at the same time. Note that the goal of this project was not to write highly efficient hand-optimized assembly code, but rather to have fun and write code that balances readability and speed. This is primarily accomplished by proper commenting and consistent code structuring." Just cool.

kwan_e,

"Whereas on the desktop and consoles gross inefficiency doesn't cost too much, in server farms, a little bit of inefficiency multiplies hardware costs."

I guess in an enormous R&D server cluster it make more sense to pay engineers to optimize the software.

Even when I was employed to work on a large corporate website distributed across multiple oracle-RAC nodes, they still seemed to prefer the hardware route over software optimization. The fix for shoddy performance was investing in faster hardware. It wasn't really my preferred way of doing things, but it seems to be the norm at all of my former employers and clients. I'd love to hear more specific counter examples though because I'd be curious to understand how they manage to buck the trend.

Now it is even worse, thanks to virtualization.

If you need a few more machines, just right mouse click on your snapshot image and select clone or similar operation, in a few minutes you have a new machine serving requests.

This beats the salary of any engineer worth his/her salt in optimization.

However, I am aware that one of the reasons for the whole going native discussion started by Microsoft is the electricity cost of using VM implementations for programming languages.

FB started the efforts for the PHP compiler, now JIT, because of that. Andrei Alexandrescu mentioned in a C++ conference, that FB measures requests per Watt on their compute center.
