This appendix provides technical background on how the Unix operating
system manages processes. This information is important to understand
if you are concerned with the details of system administration or are
simply interested in Unix internals, but we felt that it was too
technical to present in the body of this book.
is a multitasking operating system. Every task that the computer is
performing at any momentevery user running a word processor
program, for examplehas a process. The
process is the operating systems fundamental tool
for controlling the computer.
Nearly everything that Unix does is done with a process. One process
displays the characters login: on the
users terminal and reads the characters that the
user types to log into the system. Another process spools PostScript
to the laser printer. (If you dont have a
PostScript-based printer, yet another process translates PostScript
into whatever language your printer happens to usefor example,
PCL.) On a workstation, a special process called the
window server displays text in windows on the
screen. (Another process called the window
manager lets the user move those windows around.)

Certainly, the prospect of nuclear war, or even of an isolated nuclear explosion in a populated area, is a terrifying one. So far, humanity has managed to show considerable restraint in its application of nuclear weapons, but an estimated 20,000 nuclear warheads still exist in the world’s military arsenals. Ridding ourselves of this menace remains one of the most important outstanding issues in international politics. Hopefully, access to the kind of information offered by the HYDESim site will bring home to people how tragic the possibilities are, and just how imperative it is that the menace never becomes a reality.
• The Nuclear Weapons FAQ (http://nuclearweaponarchive.org/Nwfaq/
Nfaq0.html) answers a lot of common questions about nuclear weapons.
• The Atomic Archive’s New York example (http://www.atomicarchive.com/
Example/Example1.shtml) illustrates a situation much like the one shown in
Figure 3-12, only in much more detail.

‘Something whose absence would render the universe futile’. With this superb formula Lacan places his verbal seal on a concept never even traced by Freud’s pen. Enjoyment [jouissance] makes its entry to psychoanalysis, where it had, in the end, always been expected (so much so that one was not even surprised not to find it there, so convinced was one that it must surely be there already). In the period of Anglo-Saxon hegemony this absence was noticed even less due to the fact that there is no exact translation for jouissance in English (or American). ‘Enjoyment’, which is usually made to serve, does not, in the view of the Anglo-Saxons themselves, suit the task. What is lacking is the tissue of meanings which French condenses into this word.
Jouissance encapsulates, in fact, different ideas: a full and complete satisfaction, especially regarding sensual matters; and the possibility of extracting from an object the pleasures or the advantages it might offer, and—sometimes—of having acquired the right to do so.20 These diverse situations show clearly that, in the end, jouissance is the attainment of an absolute satisfaction, a pleasure with no limits—this is the aim sought. Jouissance is the acme of unchecked pleasure where the subject loses itself in ecstasy, the orgiastic pinnacle which implies that any obstacle preventing one’s access to the desired pleasure has been removed. It implies a position of mastery, the object supplying exclusively the demands of the Master, or else due authorisation in the name of the Law. Thus, jouissance is, seemingly, the privilege of whoever dominates by force or by right, or by both together.
Horseshoer’s clothes are not particularly distinguished, but there are some peculiarities. Steel-toed boots are usually a good idea for protecting the farrier’s foot from getting smashed, but there are always stories about some horseshoer or another getting his steel-toed boot stomped on by a heavy horse and having the steel plate trap his squashed toes in the boot. It would take a jaws-of-life (or jaws-of-foot) to get these squashed toes free from the boot. You would have to cut off the bottom of the boot to get them out. As gruesomely dangerous as this sounds, I’ve still always worn steeltoed boots. I haven’t had my foot stepped on much, but I suspect I would if I even thought about going out in tennis shoes. And horseshoers being what they are, there’s always someone who does wear tennis shoes. It’s so they can get away fast, they’ll say.
I never wear a ring while working with horses. I take off my wedding ring and put it somewhere safe in the truck, a long ways from the horse. I also put in the truck my wallet and everything else I don’t want lost in the dirt. My fear about my ring, more like a nightmare, is that a horse will step
