Eleven is Louder writes about the unix philosophy and linux today. Well, hes right and wrong, but mostly he misses the point!
As a programmer, atleast for me, the Unix philosophy is more about making the programmers life simple by making the tools "ortagonal" and standardizing the interfaces on read/write semantics, then it is about the command line interface.
Of course we can have a modern system based on those ideas! For example:
Sound: Instead of this horrible buggy complex mess that is alsa+pulseaudio, we can archieve the same thing, today, with OSS4¹ and NFS, SSH or Samba. And we get portability, higher quality mixing, lower latency and an easier programming interface for free.
KIO-slaves: Whats the point of of the KIO subsystem when FUSE exists? NIH in all its glory. Fortunatly KIO-FUSE exists, so you can access a textfile inside a tarfile on a remote webdav share with any program, not just KDE centric ones.
X: Lets drop the whole mess! The only thing it does nice is forwarding, but even that is botched compared to what it could be! Try using it without a hacky NX server over anything but a local link and you know what im talking about! Wayland seems like a clean codebase to replace it with, and it can even run X within itself!
But even Wayland dosn't adhere to the Unix philosophy: the way to do X unixy would be to make every application window a bitmap, toolkits into generators of bitmaps, all manipulated by unix tools like imagemagick, which in turn can be accelerated by opengl/cl. All shared over NFS, Samba or SSH.
Check out plan9 from bell labs, its in many ways the successor to Unix.
We can have a modern system, based on the spirit of the Unix philosophy!
¹ Not the OSS of the 90s. Yeah, it sucked, get over it.
Very late edit: I have since learned that my own experience of sound networking only worked by dumb luck, and wouldnt in reality. Still, the P9P networkprocol for device sharing could be ported.
