Couple of days ago, there was a blog post about how Gmail team improved the loading sequence, trimmed the 24 http requests down to just 4 requests. A few utilities and tips were covered in the post, but I think the key messages they sent across were “the need for speed” and “the obsession of great performance”.
In the good old days, we measured the greatness of a program by how fast it could run, how small the runtime file was and how smart the logic we coded. It’s the obsession of great programming, you know. Compare this to the generation of developers we have now, the first question they usually ask about a new task of programming is “where can I copy it ?”. What a difference ?!
I can understand the merit of DRY (Don’t repeat yourself), but really, there is no shortcut to be a great developer. The only way is – obsess to your work !!
