To the contributers to this book:
|

|

I have succumbed to the temptation you offered in your preface: I do write you
|
||||
off as envious malcontents and romantic keepers of memories. The systems you
|
||||
remember so fondly (TOPS-20, ITS, Multics, Lisp Machine, Cedar/Mesa, the Dorado)
|
||||
are not just out to pasture, they are fertilizing it from below.
|
||||
|
||||
Your judgments are not keen, they are intoxicated by metaphor. In the Preface
|
||||
you suffer first from heat, lice, and malnourishment, then become prisoners in
|
||||
a Gulag. In Chapter 1 you are in turn infected by a virus, racked by drug
|
||||
addiction, and addled by puffiness of the genome.
|
||||
|
||||
Yet your prison without coherent design continues to imprison you. How can
|
||||
this be, if it has no strong places? The rational prisoner exploits the weak
|
||||
places, creates order from chaos: instead, collectives like the FSF vindicate
|
||||
their jailers by building cells almost compatible with the existing ones, albeit
|
||||
with more features. The journalist with three undergraduate degrees from MIT,
|
||||
the researcher at Microsoft, and the senior scientist at Apple might volunteer a
|
||||
few words about the regulations of the prisons to which they have been
|
||||
transferred.
|
||||
|
||||
Your sense of the possible is in no sense pure: sometimes you want the same
|
||||
thing you have, but wish you had done it yourselves; other times you want
|
||||
something different, but can't seem to get people to use it; sometimes one
|
||||
wonders why you just don't shut up and tell people to buy a PC with Windows or a
|
||||
Mac. No Gulag or lice, just a future whose intellectual tone and interaction
|
||||
style is set by Sonic the Hedgehog. You claim to seek progress, but you succeed
|
||||
mainly in whining.
|
||||
|
||||
Here is my metaphor: your book is a pudding stuffed with apposite
|
||||
observations, many well-conceived. Like excrement, it contains enough undigested
|
||||
nuggets of nutrition to sustain life for some. But it is not a tasty pie: it
|
||||
reeks too much of contempt and of envy.

Creators Admit C, Unix Were Hoax
|
||||
|

FOR IMMEDIATE RELEASE
|
||||
|
||||
In an announcement that has stunned the computer industry, Ken Thompson,
|
||||
Dennis Ritchie, and Brian Kernighan admitted that the Unix operating system and
|
||||
C programming language created by them is an elaborate April Fools prank kept
|
||||
alive for more than 20 years. Speaking at the recent UnixWorld Software
|
||||
Development Forum, Thompson revealed the following:
|
||||
|
||||
"In 1969, AT&T had just terminated their work with the GE/AT&T Multics
|
||||
project. Brian and I had just started working with an early release of Pascal
|
||||
from Professor Nichlaus Wirth's ETH labs in Switzerland, and we were impressed
|
||||
with its elegant simplicity and power. Dennis had just finished reading Bored of
|
||||
the Rings, a hilarious National Lampoon parody of the great Tolkien Lord of the
|
||||
Rings trilogy. As a lark, we decided to do parodies of the Multics environment
|
||||
and Pascal. Dennis and I were responsible for the operating environment. We
|
||||
looked at Multics and designed the new system to be as complex and cryptic as
|
||||
possible to maximize casual users' frustration levels, calling it Unix as a
|
||||
parody of Multics, as well as other more risque allusions.
|
||||
|
||||
"Then Dennis and Brian worked on a truly warped version of Pascal, called "A."
|
||||
When we found others were actually trying to programs with A, we quickly added
|
||||
additional cryptic features and evolved into B, BCPL, and finally C. We stopped
|
||||
when we got a clean compile on the following syntax:
|
||||
```
|
||||
|
||||
``` <!---c-->
|
||||
for(;P("\n"),R=;P("|"))for(e=C;e=P("_"+(*u++/
|
||||
8)%2))P("|"+(*u/4)%2);
|
||||
```
|
||||
|
||||
```
|
||||
"To think that modern programmers would try to use a language that allowed
|
||||
such a statement was beyond our comprehension! We actually thought of selling
|
||||
this to the Soviets to set their computer science progress back 20 or more
|
||||
years. Imagine our surprise when AT&T and other U.S. corporations actually began
|
||||
trying to use Unix and C! It has taken them 20 years to develop enough
|
||||
expertise to generate even marginally useful applications using this 1960s
|
||||
technological parody, but we are impressed with the tenacity (if not common
|
||||
sense) of the general Unix and C programmer.
|
||||
|
||||
"In any event, Brian, Dennis, and I have been working exclusively in Lisp on
|
||||
the Apple Macintosh for the past few years and feel really guilty about the
|
||||
chaos, confusion, and truly bad programming that has resulted from our silly

In an announcement that has stunned the computer industry, Ken Thompson,
|

Dennis Ritchie, and Brian Kernighan admitted that the Unix operating system and

||||
C programming language created by them is an elaborate April Fools prank kept
|
||||
alive for more than 20 years. Speaking at the recent UnixWorld Software

Development Forum, Thompson revealed the following:

"In 1969, AT&T had just terminated their work with the GE/AT&T Multics
|
||||
project. Brian and I had just started working with an early release of Pascal
|
||||
from Professor Nichlaus Wirth's ETH labs in Switzerland, and we were impressed
|
||||
with its elegant simplicity and power. Dennis had just finished reading Bored of
|
||||
the Rings, a hilarious National Lampoon parody of the great Tolkien Lord of the
|

Rings trilogy. As a lark, we decided to do parodies of the Multics environment

and Pascal. Dennis and I were responsible for the operating environment. We

<p>Creators Admit C, Unix Were Hoax</p>
|
||||
<p>FOR IMMEDIATE RELEASE</p>
|
||||
<p>In an announcement that has stunned the computer industry, Ken Thompson,
|
||||
Dennis Ritchie, and Brian Kernighan admitted that the Unix operating system and
|
||||
C programming language created by them is an elaborate April Fools prank kept
|
||||
alive for more than 20 years. Speaking at the recent UnixWorld Software
|
||||
Development Forum, Thompson revealed the following:</p>
|
||||
<p>“In 1969, AT&T had just terminated their work with the GE/AT&T Multics
|
||||
project. Brian and I had just started working with an early release of Pascal
|
||||
from Professor Nichlaus Wirth’s ETH labs in Switzerland, and we were impressed
|
||||
with its elegant simplicity and power. Dennis had just finished reading Bored of
|
||||
the Rings, a hilarious National Lampoon parody of the great Tolkien Lord of the
|
||||
Rings trilogy. As a lark, we decided to do parodies of the Multics environment
|
||||
and Pascal. Dennis and I were responsible for the operating environment. We
|
||||
looked at Multics and designed the new system to be as complex and cryptic as
|
||||
possible to maximize casual users’ frustration levels, calling it Unix as a

parody of Multics, as well as other more risque allusions.</p>
