Then vs Now Programming WAS: Re: AMD vs Intel memory managemement

[Kevin Brown]

  "Anyone can cook. But not everyone can become a great chef."

As more and more people have gained access to the tools, the level of 
proficiency to use said tools has dropped. One example from this thread.

"Linux used to be rock stable, now it crashes every three months"

More people are trying to make it work with more and disparate hardware. 
That makes it harder and harder for a coder to really optimize the 
performance of any given amount of code. So that optimization comes in 
later... at the compiler generally. This is why Intel spends so much on 
their compiler and performance gains are seen just from changing 
compilers. But that optimization comes at a price. It won't work as well 
on AMD processors. It can't be used at all on Sparc, Power, etc...

The real bloat comes when you find out things like a microsoft developer 
crammed a limited version of their Flight Simulator into Excel... and 
that inclusion made it to release. Or the different ways you access 
functions aren't the same code in the backend... which means they were 
probably made by different developers at different times under different 
conditions. So now you have multiple, similar yet different, copies of a 
function in the compiled code. Same thing with Linux and all the 
different libraries and GUIs and other applications...
