I politely disagree - they are funny, in a wink-wink, nudge-nudge sort of way (if you've read your Lovecraft), but pale compared to his 'harder' SF (like Accelrando, Singularity Sky, Glasshouse). That said, I do much prefer the Laundry Files stories to The Merchant Princes, but I have a low tolerance for Urban Fantasy...
`make menuconfig` still works fine, I use it to configure kernels for use on Android. Since I build those on a server somewhere on the 'net - actually it sits under the stairs but for all intents and purposes it could have been on the other side of the world - it is handy to be able to use a console-based method.
I do prefer `menuconfig` (combined with `oldconfig`) in any case, possibly out of habit but also because this type of text-based user interface often is much faster to use than its graphical equivalent.
Not really. I just don't bother building my own kernel any more - the distro I use (Ubuntu Studio) comes with one that works great out of the box. Nice to know I still could, though .. ;)
How quickly can one build and how quickly can it scale ? - Speed is the name of the game - is it not this rule which holds true when building things on internet.
Or else, most of top internet apps are just going to be php,rails,node web-apps
