7/11 who offers classes on PHP in the east bay area? work is paying.
\_ take the money and go get some cheap whores... why would you
want to take a PHP class?
\_ d00d! "cheap"?! do you realize how much a "PHP class" is likely
to cost? this'd cover an all-night orgy with half a dozen
top-notch professionals...
\_ Don't bother. If you know perl, you can learn PHP. It's
simpler, albeit with uglier syntax, and, IMHO, inferior. If
you don't know perl, learn it. If you can't learn perl, you
obviously have issues with functional programming languages,
and won't be able to learn PHP.
\_ Dude. If Perl is a functional programming language then the
Moon is made of green cheese. Lambdas do not a functional
language make. Perl is about as procedural as they come.
It's proud of it in fact. Perl is evil. Look at Ocaml if
you want to know what Perl could have been if it was a good
little language.
\_ Hah! Shows what *you* know! You can do ANYTHING with perl!
even get yourself fired!!1! err....hold on a second....
that came out wrong.... |

7/2 How do I change the path perl checks when I do a "require"?
\_ Ocaml >> perl.
\_ use lib "/my/module/directory";
See "perldoc perlfaq8" for details.
\_ This probably still works:
BEGIN { push (@INC,"/my/dir/with/modules") ; }
\_ It does; see "perldoc lib" for the differences.
\_ lib is a perl module (.pm) right? I generally
avoid those since they are not compatible with
perl4 (yes people still use this).
\_ If it's a script, I find it easier to just change the #! line to:
#!/path/to/perl -I/my/module/directory |

6/22 Is there a utility that helps you decode a hex dump? I want a tool
that lets you enter each field and the size of each field. Then it
takes in an ASCII hex dump and then decodes it according to the
field information. I'm getting a headache reading all these hex
dumps. Thanks.
\_ perl is your friend.
\_ Perl is the jism of satan.
\_ is that a bad thing?
\_ I didn't know Saddam Hussein had a csua account.
\_ Get off my dick.
\_ I'm the hot gay dragon.
\_ What kind of a Marine are you???
\_ indeed. try "perldoc -f pack"
\_ scanf("%x", ...)?
\_ listen guys, I do not want to write any code to do this. I'm
looking for an application already written. Free or shareware
would be nice. thanks.
\_ An application to do this would require you to specify the
format of your particular dump in some kind of detailed
manner. Jeez, just write the 5 or 10 lines of code it will
take.
\- possibly emacs hexl-mode --psb
\_ what platform? if Windows, frhed will let you do something like
this, although it's a bit limited (byte/short/int/long/float/double
fields only; can't specify bit-fields, can't specify arrays, etc.)
\_ exactly. you could specify a text file with type/size
information with each field, etc. ok, making a custom program
to do it wouldn't be hard, but an already-existing, general
program would be still be easier. |

4/26 I'm looking for software that can do the following. Anybody know
of such a package for a small business?
1. Track customers' data and their order history. Plus I need to
enter customized data fields that can be searched. E.g, "list
all customers who ordered XYZ".
2. A way to combine information from a arbitrary number of customers.
E.g., "list all order from all customers from such date to such
date".
3. Some minimum accounting functionality. Accounts payable, accounts
receivable. Simple stuff.
I'm doing all this stuff in Excel. And it's getting hard to manage.
I need like a small database with a customizable front-end. But with
a lot of small-business functions preconfigured. Thanks.
\_ /usr/bin/perl or /usr/local/bin/perl on some systems.
\_ Used to do this in Access. It is Easy(tm) but not worth the effort
compared to either PeachTree or QuickBooks Pro. Both do full
accounting, rudimentary customer management, and full order mgmt.
\_ I was also going to reccommend peachtree, just as long as you don't
ever intend to become a big (or even medium) sized company, 'cause
peachtree is definitely a small business only system (or was 6 yrs
ago when i last used it. Things might have changed.
\_ How about UNIX based systems? Anyone? Ones that will work with
a postgress backend database maybe? or should i not hold my breath?
\_ I'm looking at PeachTree and QuickBook web sites. They are also
offering online version of the products. Like QuickBase. It keeps
customer information in their database and you use a web browser
to access it. Anybody used it? Comments?
\_ QuickBooks easily does this for you. It isn't the most
sophisticated piece of software, but it works. From what you
describe, you do not need QuickBooks Pro. And you could perhaps
use QuickBooks for the Web, although it only works on Windoze and
only works with Internet Explorer (yes, they are lame... don't even
get me started). And if you want QuickBooks for cheap ($50), I can
get it to you. -phale |

4/23 Anyone know of a pretty print util for Windows 2000? (I had a2ps for
so, where can I get it? (Please, no suggestions to change OS.)
\_ print utility to do what?
\_ Sorry, meant "pretty print" for source code (c++ perl, etc.)
\_ You meant something like enscript? If your printer driver
supports two pages per sheet, you can simply open your source
file as plain text and print with that feature. Otherwise,
You can create a template in M$ Word to use landscape
orientation, two columns, and a small mono font. Then open
a new document with that template and paste in your source
code. Then print it. (The latter was how I printed enscript-
like output on my 9-pin printer years ago.) Either way, don't
forget to also utilize any two-sided printing feature to save
even more paper. -- yuen

\_ http://gnuwin32.sourceforge.net/enscript.htm
\_ Enscript is similar to a2ps--I was under the impression that
enscript had been absorbed into a2ps.
\_ emacs
\_ Wow, emacs sends to the printer? And formats the code like a2ps?
Are you sure about this?

Perl: Active-X, VBScript, J[ava]Script, PHP,
ASP, JSP, C#, Pascal, Lisp (and derivatives).
\_ Young troll, you will become more effective
if your arguments are plausible. Now what

a slow useless POS.
The list is practically endless. About the
only decent languages in existence are C/C++,
Perl and Java (and even that is debateable).
\_ Without starting a Perl flamewar--why did you
list Active-X as a language?
\_ LOL, I think he meant COM.

4/11 If I add in mod_perl, is there anything extra I have to do on the

\_ Yes. There is a guide with the mod_perl documentation that
tells you what to do. Mod_perl is MUCH pickier than most Perl
programmers. That is to say, your scripts may require a lot of
reworking. --sowings
\_ I think the most common catch'em (for me) is that my CGIs
operated on the assumption that variables == 0 or empty string.
Alas, when run under mod_perl, variables tend to have the value
from the last time they ran (can't depend on this though),
so you need to make sure you always reinitialize things.
\_ 1) Good thing you don't write in C (or perhaps you don't
write your C this way).
2) This is because mod_perl caches scripts. If the script
hasn't changed on disk, the server doesn't have to
recompile it. This is what buys you performance.

"use strict;" in the code, you'll get a good idea of

\_ Sun did. It's called "Java".
\_ this is a stupid answer. POSIX api *is* supposed to be
the multiplatform solution. opendir/readdir/closedir
are very much multiplatform and are definitely not UNIX
only. if your OS doesn't support it, looking for YET
another "standard" library is asking for lack of
portability. -ali.
\_ Java is better than POSIX. POSIX
compliance is limited mostly to UNIX
systems (and WinNT) while Java is
usable on Mac,Win*,*nix and others.

Perl is faster for simple form processing
and basic text output. But how many cgi's
do that anymore. Most are wrappers for
accessing services like a db or ldap or
corba or a tib. Perl loses here.
Benchmark a java servlet that does jdbc
odbc access using a connection pool
against a perl cgi that needs to open
a db connection every time it is invoked.
Java beats the pants off of perl for
most transactions. Same for LDAP. I
know that Java is better since I worked
to convert a large perl cgi based product
(worked on the perl cgi's in the original
version) to java servlets for Cisco and
we got ~ 1.5 to 2x improvement on the
server side performance. Setting up JRun
or Appache JServe isn't that hard. If you

mod_perl does not need to open new
database connections every time;
that's what Apache::DBI is all about.
And saying you got a performance
improvment over "perl cgi" is idiotic.
Of course you did, the compile/exec
penalty on non-mod_perl is lethal.
\_ We were using mod_perl, but Apache::DBI
wasn't stable enough for our needs.
\_ POSIX API exists for most OS's.
\_ Tcl/Tk also has platform independant APIs for this kind
of thing. I've used Tcl/Tk and I highly recommend it. -emin
\_ Tcl/Tk is pretty junky compared to Perl. If you need
to use a scripting language use Perl or Bourne Shell.
\_ there really is no point in doing Tcl in my opinion.
Instead you should use python. It's easier to learn,
it's easier to write wrappers for your C code in it,
it runs faster (actually, i don't know about tcl8.0),
and it's got builtin support for OO. -ali

\_ Certain variables cannot be my'd. Basically, think of

1/26 Some friends of mine are having problems with memory
management in Java. Is there a way you can force
garbage collection in Java? Alternatively, is their
a way you can do memory allocation similiar to C/C++
where you can explictly allocate and deallocate stuff
so that you aren't at the mercy of the garbage collector?
\_ java 1.1: System.gc(); System.runFinalization;
in that order, to force garbage collection and
call all object finalize() methods.
\_ Does that actually FORCE garbage collection, or does
the system just treat it as a suggestion? Thanks.
\_ depends on the java VM. The ones I've worked with
actaully do a GC when you ask for one, but this
is not required by the language spec. - seidl
\_ Are you sure the problems are caused because the VM isn't
doing a gc? You could have objects which you think are dead,
but are still referenced and therefore not up for GC. You'll
need to use some tools to figure out.
Also, the VM you are using is important. Some Java VMs out there
use conservative gc, in fact I think all the Sun VMs before
HotSpot (which has an exact garbage collector) used conservative
gc. With conservative gc's, it's possible to have objects which
are collectable, but the garbage collector isn't *sure* they are
collectable, so to be safe it doesn't collect them (this can not
happen with an exact collector).
\_ Dude, if garbage collection is so complicated and delicate,
what the heck is the point? If I'm going to worry about
memory management with GC, why not just use new and delete?
New and delete are nice and simple and you don't have to
worry about all this weirdness; you just clean up after
after yourself.
\_ Implementation of GC is complicated and delicate, but
the use of a GC'd runtime system isn't. Or at least,
it shouldn't be -- the problem here is that the people
who originally designed an implemented Java are morons
(if you need any more proof, look at java.util.Date).
When using any reasonable garbage collector (like one
in any Smalltalk or the Java HotSpot), you just make new
objects and the garbage collector will reclaim when they
can no longer be used.
Now, you could make a programming error where something
you think should no longer be useable still is, but
if you have good programming habits, that shouldn't happen
very often. Far less often than memory leaks with malloc,
free.
\_ Also, if you set the variables' value to null I believe it will
be marked for garbage collection. Of course, this won't _force_
gc.
\_ This is a myth -- nulling vars does not help gc. Either
you need
the objects in those vars, in which case they should not be
up for gc and they should not be null (of course); or you
don't need them and you don't need the class holding on to
those variables, so the root class should be up for gc and
its ivars should be up for gc also.
I guess the above is not true if you have a class that is
long lived but puts objects that it only needs for a short
time into an variables, but that *probably* is a bad design.
\_ Perl has great GC mechanism, is easier to program (little error

\_ 40$ if you're not very good, but still call your self a sys admin

\_ Entry level sysadmins do not get $80k a year. You must be
talking $40k a year, not $40 an hour.
\_ Entry level contracting coudl easily be 40/hr if you're not a twit
and you go to a pass through agency (ie, not taos). But it doesn't
have benefits, so might translate close to $65k on annual basis.
\_ I thought the rule of thumb was $10/hr ~= $10k/yr for contractors.
\_ No. Normal rule is yearly salary = 2000 * hourly rate.
\_ That's just the raw pre-tax, pre-everything amount, though.
Just keep in mind that you don't pocket that much each year.
\_ Also, full timers tend to get much better non-cash benefits
than contractors. You'll have to weigh the value of these
benefits vs. more cash as it pertains to your life. Also,
some benefits are never worth it when you can buy them with
the higher salary you might make elsewhere.

you can use "wget" or other executables compiled for

6/23 Here's a question. I'm trying to send and receive a large file from one
machine to another. To do this I've used a SOCK_STREAM with TCP
protocol. It works fine normally as I read away from the socket.
However when I get transfer-encoding:chunked, for large files. I get
a portion of the file, but soon the sysread returns 0 bytes read.
However its not done with the file yet, it never finishes, the socket
stays open but it never sends the rest of the data. I'm doing
this all in Perl but C solutions will work too.
\_ for large amounts of data you can end up reading only a portion
of the data you want in one read call, and need to wait for more
data to arrive (the sysread of 0 means no data currently in the
buffer, but you might get some more in a few hundred milliseconds)
\_ I thought of that. So I looped the read until I got the chunked
exit value. No luuck I get an infinite loop. Nothing ever
comes in on the socket again.
\_ Could be a problem on the send-side (not sending
subsequent chunks). Could be you're not properly
recognizing the 'chunked exit value' on the
receiving side (the bunches of bytes you read
won't necessarily be grouped as they were sent).
Could be a lot of things -- are you writing

the first line of the script to show it where perl 5 is installed

\_ Stop whining. You can always create sym links
in your bin directory and put your bin in front of
your path setting.

was "why," which regrettably assumed there was
a valid reason (which apparantly there is).

3/17 Hi, I'm looking for a mail filter that strips everything except the
flat ASCII text. All that mime type thing, HTML tags, jpg attachments,
etc, are all not worth having. I want to pipe a piece of mail through
it, so it should know the mail header as opposed to just get rid of
everything in between '<' and '>'. Thanks!
\-if you are tall enough, mailagent. --psb
\_ awk is your friend
\_ Would sed be actually easier for this case, or no?
Something like 's/<.*>//g'? (not exactly correct, but close)
\_ no. tags can span multiple lines.
\_ I pipe everything through a perl script, but not for the same
reason you do. You could easily write something that did
everything you want and more but you'd probably end up with your
own version of something that already exists anyway. I've never
looked at mailagent as suggested by psb. procmail and perl do it
for me for now. I read and reply with mh if it matters to you.
\_ That's exactly my point. I can spend the time writing a
customized filter or searching for one already written
by someone else. Ugh... It's looking more like I'll need
to write one myself. HTML mail is just annoying and evil.
But I have a feeling that the days of 100% pure flat ASCII
email are gone. -too old to change
\-mailagent has a perl escape and does some of the harder
parsing fo ryou. --psb
\_ I figured it was something like that. I just pipe all the
html-ized crap through lynx and if lynx can't deal with it,
then I just skip it and go on. Got a URL for mailagent?
\_ Ok, found it. The docs say it stops at the first match
which will break some of my filtering. Does mailagent
do anything that procmail doesn't? |

would "work" as in general I believe ya gotta pay your dues to get
the clues.. Anyone have any advice on this? --jnat
\_ yes. learn perl and make him depend on you for all his perl needs.
\_ Ho ho ho! But that's the current situation.. I guess the
only option is to teach him myself?
\_ No, don't be stupid. The above was a perfectly good
answer. Why would you want your boss to be able to do the
things you're currently doing? Are you getting paid extra
to train people at your company? Is that part of your job?
Does it enhance your career in any way to teach your boss
anything more than how to kiss your ass to get done what he

has zero coding experience. So anything he writes is going
to be crap. Your best course of action may be
1. teach him some basics
2. say why don't you try to do something now?
[give him huge project, and say "I could do this in about
a day"]
3. Either he gives up, or makes a total mess ofit.

\_ Well, someone keeps deleting this, but again:

\_ Because someone like you didn't take the time to rewrite
it to do so. What's up with everyone expecting everything
to be pre-written to do exactly what they need? Do it
yourself, sheesh.
\_ Because chances are someone has written something to
do what you want. Why reinvent the wheel? And why
suppose the person has the time or knowledge to
accomplish the task?
\_ To ask if someone else has done it is differant than
asking why they haven't. One is a query, the latter
is a whine. I don't suppose they have the time or
skill. I object to the whining not the desire to have
a feature.
\_ Well, since it knows to look into the file content to
find out if a file with no ".jpg" extension is a
JPEG file, I would think it also knows to look into the
JPEG file content to get the width and height. -- yuen

the output of a program, but the programs you want to run in the

1/11 Is there any reason Perl couldn't/shouldn't replace scheme & java
as the languages of choice for 61x? Yes, it can be damn ugly, but
the iteration/recursion difference is a lot clearer, the CPAN
provides many excellent examples of abstraction & component use,
and it's a lot easier to get perl to work on home computers (unix, mac,
or winblows) than scm/Dr. Scheme. Everything scheme & java can do
perl can too. (Well, java does win at threads for now, but that's
not taught in the 61-series is it?)
\_ does Perl support closures and upward funargs? -nick
\_ It has both static & dynamic scoping, and you can close over
statically-scoped vars.
\_ Perl is kinda messy. It also assumes you have a brain and know
something about systems as well. There's lots of niggly little
historical things in PERL that a freshy wouldn't get. Scheme,
although useless in the RW is much cleaner (as taught in freshy
courses) and there's already tons of experience at Cal teaching
it the right way. I love PERL, but I don't think it's a good
choice for a first language. Java? Which Java? heh.
\_ Perl can be learned the wrong way, and is much easier to cheat
solutions that do the "task", but in the wrong way.
\_ basically, if the 61 series is a place people can get excited
about programming and get tools they can use to actually create
useful programs themselves, perl is a good choice. If it's a
weeder series, where you're trying to knock out people who aren't
really interested by making them use a crappy language with
no practical purpose and no redeeming features, scheme is a good
choice. In a typically Berkeley manner, the department has
decided to go for the latter option. -tom
\_ um, scheme is not being used with those goals in mind at all.
scheme is used b/c that's what the book that bh likes uses,
and b/c it's a nice simple elegant language that is easy for
first-time programmers to work with. it may not be practical,
but it certainly has redeeming features. see response below.

nothing about computers (but hopefully knowing at least
"induction" which is the math version of recursion) and as they
work their way through the series the levels of abstraction
choices of syntax to use. Probably not the best choice for a
gradually go away and you end up in assembly. Remember, the goal
is not to learn an interesting language, it is to learn *about*
computer languages, about how we use computers. In languages like
Perl, a lot of other "junk" gets in the way of doing that. Also,
the Abelson & Sussman text really is a good text. Chances are if
it used Perl, Berkeley would be using Perl.
\_ Scheme is pretty much a pure functional language. It's a
good environment to learn about how to structure programs,
break problems into components, etc. It also has a rigid,
well-defined syntax. Perl is powerful, but not only are
there 100+ ways to get any task done, there are several
choices of syntax to use.
\_ and most of them disgusting.
Probably not the best choice for a
first course in functional programming.
\_ "In English Composition 61, we force everyone to write in iambic
pentameter, because the rigid, well-defined syntax makes people
broaden their vocabulary and appreciate Shakespeare more." What
a crock of shit. No amount of time spent working around the
klunkiness of a language is more valuable than time spent actually
solving problems through programming. The fact that there are
lots of ways to get stuff done in Perl is a *good* thing, if
what you want to teach is how to get stuff done. You're fooling
yourself if you think the 61 series is supposed to do anything but
weed out English majors (as English 61, above, would be designed
to weed out CS majors). -tom
\_ when i took cs61a i found it to be a very good introduction
to the concepts of programming (for a person who had never
done any before that class except a couple of lines of basic
in some lame hs computer tools class), and also friendly and
not intimidating. it didn't seem like a weeder course at all.
i'm sure the class itself has much more of a weeder feel now,
since cs is so overloaded, but i still think that scheme is a
nice language within which to teach the basic concepts. if
61a had used perl i probably would have freaked. -lila
\_ And since we all know English and CS are the same
thing....
\_ this reminds me that I switched from an english major to CS
because of 60a (SICP w/ Wilensky).. --karlcz |

12/15 How would I count the number of occurances of a pattern in Perl?
\_ the easy but incorrect way to do it is grep pattern file | wc -l
\_ In a single line? In a file? In what?
\_ Find pattern. $count++;
\_ Yeah, this would work if I'm feeding a for loop line by
line. But what if you have say $foo = "aaabbbaaacccaaa"
and you want to count the number of times 'aaa' appears?
\_ Use the same algorithm. Implement "find pattern" differently.
Twink. Try while ($foo =~ m/pat/g) { $count++ } or
$count = length($foo =~ m/pat/g);
\_ Thanx, but can anyone ask anything on this motd without
being branded a twink? I guarantee you there is not
one question here that someone won't think is trivial
or self-evident or just plain dumb.
\_ you then have to decide if "aaaaaa" matches with "aaa"
once, twice, or 5 times.

\_ tr/// it into its identical string/pattern and catch the returned

you can download only message headers under IMAP and selectively
download only certain message bodies but it seems that you can
do the same with POP.

4/15 Let me clarify on the Perl question. I have two commands need
to be spawned from a Perl script, $cmd1, $cmd2. $cmd2 depends on
$cmd1. However, $cmd1 and $cmd2 are called millions (no, not an
exaggeration) of times in a foreach loop now with different
arguements each time, so performace suffers. Now the question is,
how to run each set of $cmd1 and $cmd2 in parallel while still
keeping $cmd1 and $cmd2 to run in serial? I tried system but
failed. Each set of $cmd1 and $cmd2 waits for the previous set
to finish...
\_ run fork, and have each child system $cmd1 then $cmd2, then
exit. The parent process just forks a million times,
then exits. Now, make sure to run this on a big box, or
million perls will bring you to your knees. - seidl
\_ Is there an alternative? fork-ing a million times
is expensive even on a big box. (I just ran a simple
script that forks 10,000 times and it increased the system
load by 10-fold, and it also forbids more processes to be
spawned). Can we execute each set in parallel w/o fork?
Thanks. Or maybe it wasn't pratical to try to run these
millions of set of commands in parallel in the first place?
\_ depending on the speed needed, spacing out the forkings
might be a good idea (just sleep 0.1 secs between each
pair or something like that)
\_ So thats 100k seconds per million iterations roughly
equals 27 hours per run? 3 million = 81 hours. I think
not. That 27 hours is only the added delay between runs
and does not include actual runtime for the binaries.
\_ doh. well again, it depends on the binaries'
runtime. 27 hours might be acceptable if it means
not killing an overloaded server. Adjust the figure as
as appropriate for a faster box
\_ Uh, how do you plan on running different commands without
forking separate processes?
\_ errrr...good point. So fork is the only option when
you want to run things in parallel? How does UNIX
shell execute two background commands? By forking
twice?
\_ Yep. Thats how you get a new process. fork.
Now, you might be able to avoid the extra perl
processes with creative use of system("$cmd1 ; $cmd2");
but a million jobs in parallel is a lot. - seidl
\_ Instead, sh was spawned. Is that necessarily
faster than spawning perl itself?
\_ Fork isn't the only way to run tasks in parallel --
you can thread things too. But unix command-line
programs can't be run in threads.
\_ you cna also call system("$cmd1;$cmd2 &");
\_ buy a clue. system forks implicitly
\_ if forks but it also waits till completetion you dumbass.
try the following in perl
system("echo foo; sleep 10");
system ("echo bar");
note that it prints foo, then waits for 10 seconds, and then
prints bar. -aspolito
\_ Ok... can you rewrite the unix binaries so that you're only doing
a single system call from perl and the binary does the looping
without forking? Are the command line parameters known before
or non-deterministic based on user input, the time, or grains of
sand on the beach? I agree with the previous person that doing
millions of calls to a binary from perl is a bad way to go.
Rewrite the C, if possible, to relieve PERL and the system of this
forking burden. |

3/19 Is there a way to use PERL or some other scripting language to
create a windows95/nt shortcut? I want to have something like a
.bat file create a bunch of shortcuts then delete itself. It
can't be GUI based or interactive beyond an initial double-click.
Pointers, URL's, etc, all welcome and appreciated. -stuck
\_ http://www.perl.org/CPAN/ports
\_ I got it and version 0.03 of the Shortcut module worked
perfectly with a recent version of win32perl. Thanks! |

3/18 Has anyone (else) encountered a bug where after using lseek with
a negative offset read stops working on that fd, even though a
valid off_t was returned? In particular, I have a file with two
binary unsigned longs at the end, and when I do an lseek(fd,
-2*sizeof(unsigned long), SEEK_END); the reads then fail. -mel
\_ Use PERL.
\_ Did you try seeking to the beginning to the file, then a forward
seek to where you want to read as a work-around?
\_ The file is full of longs and I had wanted to read the two
longs at the end of it. The workaround I found was:
end_offset = lseek(fd, 0, SEEK_END);
lseek(fd, end_offset-2*sizeof(long), SEEK_SET);
which is ugly but it works. Throw in a few error checks
on the return codes and it should work for you too. -mel
\_ mel you ugly squint, get off the motd
\_ And now, the right answer: You are specifying a seek relative to
SEEK_END... Such a seek is implicitly in the negative direction,
since it's impossible to seek past the end of the file. The minus
sign in front of the 2 is unnecessary. So you should be doing:
lseek(fd, 2*sizeof(unsigned long), SEEK_END);
I tried looking for an example of this in K&R, but in each instance
where SEEK_END is used, they demonstrate with an offset of 0, which
is not too instructive. WHY HAST THOU FORSAKEN ME, K&R? I TOOK
THY WORD AS GOSPEL ONLY TO FIND A HALF-TRUTH LYING IN WAIT TO SNARE
THE UNWARY! -mogul (hey, it's 3:15am, fuck off!)
\_ Not quite. A seek from SEEK_END is not implcitly negative;
just like SEEK_CUR and SEEK_SET, positive offsets go forwards
and negative offsets go backwards (see lseek(2)). The problem
with your code (and it's not really your fault) is that sizeof
returns a size_t, which (on freebsd) is an unsigned int; when
you multiply that by -2, you get another unsigned int (K&R 2.0,
p. 198); and the unsigned int (0xfffffff8) then gets promoted
to a signed long long (0x00000000fffffff8).
This is not what you want. The Right Way to fix it would be
for freebsd to make size_t an unsigned long long, but that
would break a lot of stuff and probably won't happen soon; in
the meantime, you can cast the return value of sizeof to a
signed int and your code will work. --mconst |

3/18 looking at mi professors and tas and manager resumes, these people dont
know how to c0de shit in perl and c/c++ and shell and java, yet they
make/will make more $ than me, what the fuck?
\_ I have actually heard a manager refer to programmers, unflinchinly,
as "unskilled labor", by which I think he meant disposable/inter-
changeable or something. Im not sure
\_ It depends on what kind of application you develop. I would
not call people developing optimized 3d game engine or
financial application "unskilled".
\_ No, people who develop financial applications are unskilled.
Gamers are pretty cool, though.
\_ demand for a raise and see how high you can go
\_ Because coding is for kiddies. You can teach any idiot how to
code. It really isn't that hard. Look how many idiots are doing
it right now. No PhD required. If you wanted to make big bucks
you went into the wrong field and now possess the wrong skills.
Sorry, but you're pretty confused about the world and your career
is already fucked. Time to retrain I guess.
\_ It doesn't matter anyway; when bh and his Communist GNU buddies win,
you'll all be writing code for free. (Hope you like doing
support . . . )
\_ POT STICKER POWER! YEE HAA! Actually I'm glad we have
self appointed victims like the FSF/GNU people but I
wouldn't want to be one.

ULTRIX cc!) I, for one, am rather thankful to have
cross-platform tools that *work* for a change... -brg

2/10 Perl is a great language. However, how do you pass by reference
a complex data structure? I am able to pass by reference a simple
list when my subroutine refers to $_[$num], but when I have to
pass a hash of hash and hash of list, I don't know how to change
the referenced value anymore! Please help, thanks.
\_ See "perldoc perldsc" for examples and an explanation.
\_ list of hash and list of list are easier to demonstrate:
%h1 = %h2 = %h3 = ();
$loh = (\%h1, \%h2, \%h3);
($h1ref, $h2ref, $h3ref) = @$loh;
similarly:
@l1 = @l2 = @l3 = ();
$lol = (\@l1, \@l2, \@l3);
($l1ref, $l2ref, $l3ref) = @$lol;
get it?
\_ Yes, that I get, but how about hash of list and hash of hash?
perldoc perldsc does not explain any of this. Thanks.
\_ IT"S THE SAME WAY: %obj = ('alphabets' => ['a', 'b', 'c'],
'numbers' => [1, 2, 3],
'subs' => [ &get, &put, &set ]);
\_ elements of hashes and lists must be scalars. This means
that you have to have lists of hash refs and hashes whose
values are refs of whatever thingies you want. Boy this
is confusing, but I hope I answered your question.
\_ oh man, took me a whole week to figure this out. pUrl
sucks!!!!!!!!!!!! Now I have to create a totally separate
class to handle pass by reference a "slightly" more
complicated data structure.
\_ Nothing wrong with the lanauge. You just suck because
you didn't RTFM *before* you spent a week writing
total crap code. "WAAAH! I DIDN'T READ THE MANUAL
SO IT SUKZ!!!!!"

2/3 Perl gurus who think you're all hot:
print scalar localtime(2100000000) = year 2036
print scalar localtime(2200000000) = year 1903
So Perl and most UNIX shit are not year 203X compliant?
\_ The unix universe ends at 2037 or 2038, I forget which. So,
no, unixes in general are not Y38+ compliant. Perl is probably
just passing along whatever the system is telling it.
\_ make that the 32-bit Unix universe - 64-bit Unixes will
last a few billion more years
\_ As I said, "unixes in general".
\_ some commercial vendors are starting to change their
time structs to 64-bit, so this is becoming a reality.
\_ Of course, in 2038, we will all be using 4096-bit architectures,
so this problem will go away :)
\_ This just shows you how stupid designers are, always thinking
of what's best for today, but never what's best for tomorrow.
These dumb ass engineers are dumb asses, and Clinton trying to
get even more incompetent people into high tech is just going to
make the matter worse.
\_ Please tell me this is brilliant flame bait. Because I
was laughing so hard I hurt myself. Then I though it might
be serious. Now im not sure.

coherently, I'd be enlightened. The file is located in
~god/Pub/perl.bugs
\_ 1. The first evaluates the backquote expression in list context
and stores the first element of the result in $result1. The
second evaluates the backquote expression in scalar context
and stores the entire result, as a string, in $result2. It
has nothing to do with your use of "my"; you can (and should)
rewrite the second as
my $result2 = `cp --help 2>&1`;
See "perldoc perlsub" for more information.
2. Both of your examples work fine for me. Could you elaborate
on what goes wrong when you try them?
3. You can't declare $_ with my. This is a special case in perl
which may change sometime; it's mentioned in "perldoc perlsub".
