=== ALL USERS PLEASE NOTE ======================== Compiler optimizations have been made to macro expand LET into a WITHOUT- INTERRUPTS special form so that it can PUSH things into a stack in the LET-OPTIMIZATION area, SETQ the variables and then POP them back when it's done. Don't worry about this unless you use multiprocessing. Note that LET could have been defined by: (LET ((LET '`(LET ((LET ',LET)) ,LET))) `(LET ((LET ',LET)) ,LET)) This is believed to speed up execution by as much as a factor of 1.01 or 3.50 depending on whether you believe our friendly marketing representatives. This code was written by a new programmer here (we snatched him away from Itty Bitti Machines where he was writing COUGHBOL code) so to give him confidence we trusted his vows of "it works pretty well" and installed it.
HOLY MACRO!
Speaking as someone who has delved into the intricacies of PL/I, I am sure that only Real Men could have written such a machine-hogging, cycle-grabbing, all-encompassing monster. Allocate an array and free the middle third? Sure! Why not? Multiply a character string times a bit string and assign the result to a float decimal? Go ahead! Free a controlled variable procedure parameter and reallocate it before passing it back? Overlay three different types of variable on the same memory location? Anything you say! Write a recursive macro? Well, no, but Real Men use rescan. How could a language so obviously designed and written by Real Men not be intended for Real Man use?
There has also been some work to allow the interesting use of macro names. For example, if you wanted all of your "creat()" calls to include read permissions for everyone, you could say #define creat(file, mode) creat(file, mode \| 0444) I would recommend against this kind of thing in general, since it hides the changed semantics of "creat()" in a macro, potentially far away from its uses. To allow this use of macros, the preprocessor uses a process that is worth describing, if for no other reason than that we get to use one of the more amusing terms introduced into the C lexicon. While a macro is being expanded, it is temporarily undefined, and any recurrence of the macro name is "painted blue" -- I kid you not, this is the official terminology -- so that in future scans of the text the macro will not be expanded recursively. (I do not know why the color blue was chosen; I'm sure it was the result of a long debate, spread over several meetings.) -- From Ken Arnold's "C Advisor" column in Unix Review
Most bacteria have the decency to be microscopic. Epulopiscium fishelsoni is not among them. The newly identified one-celled macro-microorganism is a full .5 mm long, large enough to be seen with the naked eye. Described in the current Nature, "It is a million times as massive as a typical bacterium."-Time, page 25, March 29, 1993
The War Against Linux A significant obstacle on the path to Linux World Domination has emerged. A reactionary grass-roots movement has formed to fight, as they call it, "The War Against Linux". This movement, code-named "LinSux", is composed of people (mostly Microsoft stockholders and commercial software developers) who want to maintain the status quo. They are fighting back against the rise of Linux and free software which they see as a threat to their financial independence. The most damaging attack the LinSux folks have launched is "Three Mile Island", a Windows macro virus designed to inflict damage on computers that contain a partition devoted to a non-Microsoft OS. When the victim computer is booted into Windows, the virus activates and deletes any non-Microsoft partitions. Ironically, the many security flaws in Windows allow the virus to damage alternative operating systems but leave Windows unscathed. "The War Against Linux" has also been fought in more subtle ways. Time-tested methods of Linux advocacy have been turned into subtle forms of anti-Linux advocacy by the LinSux crowd. MSCEs are smuggling NT boxes into companies that predominantly use Linux or Unix. LinSux "freedom fighters" are rearranging books and software boxes on store shelves so that Microsoft offerings are displayed more prominently.
Class-Action Lawsuit Filed Against Linus Torvalds SILLYCON VALLEY -- Nearly 130 former system administrators have filed suit against Linus Torvalds in which they claim Linux cost them their jobs. Recently several companies migrated from Windows to Linux, increasing their productivity but decreasing the need for a large staff of tech workers, prompting a wave of layoffs. "The good old days when it required five full-time system administrators to maintain a Microsoft Exchange server are history, all because of that cancer known as Linux," explained the lead litigant in the lawsuit. "It all started two years ago when some pimply-faced idiot down in Accounting decided to smuggle in a Linux box to automate some of his work. Before long every tech-savvy person in Accounting, Billing, and Sales was secretly using Linux." "That's when the troubles started. Productivity soared. Downtime was limited to an average of three milliseconds per day. Macro viruses ceased to spread. It was horrible! The entire IT staff was replaced by one part-time bearded wonder, who was able to administrate the entire Linux network! Due to the layoffs, I'm now sitting in a homeless shelter with little hope to find work. Nobody wants to hire an MCSE anymore!"
