Does anyone else find that each successive release of Mac OS X gets worse, more Windows-like in its obscurity, its tendency to hide affordances that were once a joy to the advanced user, more buggy, more user-hostile, with more attempts to lock you into Apple's own apps. I'm starting to hate Mac OS X, and thinking there's starting to be an opportunity for a new, simple, clean OS to come along.

Right now, since I've switched to Gmail, I'm trying to back up and remove from my machine years of accumulated mail storage from First obstacle: a user's library files are now hidden. Finally find them (thanks Matt Silver), back up the files to an external disk, and then delete them. But then when I empty the trash, an ungodly number of files--going back years--claim they are "in use" and can't be deleted. So here I am having to click "continue" every few thousand files (if I'm lucky) as I page through more than 400,00 files to be deleted. I know this is actually an old mis-feature - but why the devil wouldn't they give you an "ignore" checkbox or a "delete whatever you can checkbox"? This has been a problem for years, but never fixed, while they add new gloss all the time.

But that's just the latest frustration. There are so many things that are worse in Lion than in Snow Leopard, just as there were many things worse in Snow Leopard than in Leopard, and on back.

Time to start over, guys.

I was warmly surprised to see how many people responded to my Google+ post about Dennis Ritchie's untimely passing. His influence on the technical community was vast, and it's gratifying to see it recognized. When Steve Jobs died there was a wide lament - and well-deserved it was - but it's worth noting that the resurgence of Apple depended a great deal on Dennis's work with C and Unix.

The C programming language is quite old now, but still active and still very much in use. The Unix and Linux (and Mac OS X and I think even Windows) kernels are all C programs. The web browsers and major web servers are all in C or C++, and almost all of the rest of the Internet ecosystem is in C or a C-derived language (C++, Java), or a language whose implementation is in C or a C-derived language (Python, Ruby, etc.). C is also a common implementation language for network firmware. And on and on.

And that's just C.

Dennis was also half of the team that created Unix (the other half being Ken Thompson), which in some form or other (I include Linux) runs all the machines at Google's data centers and probably at most other server farms. Most web servers run above Unix kernels; most non-Microsoft web browsers run above Unix kernels in some form, even in many phones.

And speaking of phones, the software that runs the phone network is largely written in C.

But wait, there's more.

In the late 1970s, Dennis joined with Steve Johnson to port Unix to the Interdata. From this remove it's hard to see how radical the idea of a portable operating system was; back then OSes were mostly written in assembly language and were tightly coupled, both technically and by marketing, to specific computer brands. Unix, in the unusual (although not unique) position of being written in a "high-level language", could be made to run on a machine other than the PDP-11. Dennis and Steve seized the opportunity, and by the early 1980s, Unix had been ported by the not-yet-so-called open source community to essentially every mini-computer out there. That meant that if I wrote my program in C, it could run on almost every mini-computer out there. All of a sudden, the coupling between hardware and operating system was broken. Unix was the great equalizer, the driving force of the Nerd Spring that liberated programming from the grip of hardware manufacturers.

The hardware didn't matter any more, since it all ran Unix. And since it didn't matter, hardware fought with other hardware for dominance; the software was a given. Windows obviously played a role in the rise of the x86, but the Unix folks just capitalized on that. Cheap hardware meant cheap Unix installations; we all won. All that network development that started in the mid-80s happened on Unix, because that was the environment where the stuff that really mattered was done. If Unix hadn't been ported to the Interdata, the Internet, if it even existed, would be a very different place today.

I read in an obituary of Steve Jobs that Tim Berners-Lee did the first WWW development on a NeXT box, created by Jobs's company at the time. Well, you know what operating system ran on NeXTs, and what language.

Even in his modest way, I believe Dennis was very proud of his legacy. And rightfully so: few achieve a fraction as much.

So long, Dennis, and thanks for all the magic.

The keynote talk at Desktop Summit 2011. What an amazing talk! Check it out. Hats off to Thomas Thwaites.

"Dial An Auto" in Pune! Number to call : 9922 90 4000. Share and spread the word far and wide. Mumbai, Panvel and Bangalore - you need such a thing.

If I got one $1 for everyone who typed QT instead of Qt in various Qt mailinglists and $2 for each time someone says Q-T instead of "cute", I could have bought an island near Baba Ramdev's island.

I have no clue how this thing works. Circles? Add? Invites?

So now we have more instruments to kill time.
