3/5 For the "First Class" stamps which I bought for $0.33 but which don't
have "33 cents" printed on them, does it mean I can still use them now
34-cent stamps? Thanks.
\_ If you post a letter with 33c instead of 34c, the post office
will probably still deliever it, but they are under no obligation
to do so. I wouldn't send any bills that need to arrive in a
timely fashion with just a 33c stamp on it.
If you want to be on the safe side, buy some 1c stamps and add
them to your letters.
\_ I have sent exactly 1 under-posted letter out and got exactly
1 under-posted letter returned for more postage.
\_ No; they were first class stamps when they were printed, but their
first-classness has been superseded now that there's a newer series
of non-denominated first-class stamps. They're worth whatever the
first class rate was at the time they were printed (part of the
reason they started printing the year on stamps a while back).
\_ I just bought some first-class stamps (no value printed) from
the post office a few days ago for $0.34 each, but there are
"2000" printed on them. Does that mean I got cheated and they
are only good for the first-class rate last year?
\_ why does the PO make stamps that don't have the value printed on
them? it's silly. is it just so that they can print the stamps
before they decide on new rates? |

2/18 I have this Java program that uses ICEsoft's free version of the
browser inside a java.awt.Container object. The problem is,
the ICEsoft's free browser doesn't run JavaScript and the
full version costs way too much. Is there any cheaper
alternative? The browser needs to support JavaScript (preferrably
ECMAScript) and rich-media contents through Java Media Framework.
No, I cannot use IE or Navigator. I need to run a browser inside
my Java application, not running an applet inside a browser.

a thing?
\_ Get them to pay for a java certification. -John
\_ Like John says. If they want certified engineers and they don't
pay for it are they expecting their entire staff to go get trained
on their own dime and time? I think not. Put them on the defensive
and ask what the details of the company sponsored cert program are. |

1/9 Alright, so why does Java have both "abstract" and "interface"?
Isn't that redundant?
\_ Java is doomed. Don't get too into it.
\_ no. interfaces can't contain implementation. train harder.
\_ you too must train harder. abstract methods also don't
contain implementation. train even harder.
\_ if you think the q refers to the method qualifier, you suck.
\_ you also must train harder. you can have 1 method abstract and
implement other methods still making the entire class abstract
which means you can't instantiate it. Interfaces require
all methods abstract and thus no implementation at all.
\_ abstract modifies classes. it's useful if you want to
extend a superclass that does have some methods predefined,
in addition to some undefined/abstract methods.
whereas, interfaces cannot have any methods predefined.
Or, you only partially implement an interface, leaving some
methods undefined.
\_ And now, finally, the right answer: in Java, you can not have
multiple superclasses (abstract or not), but you can have
several superinterfaces. Interfaces are Java's way of doing
multiple inheritance while avoiding the virtual base class
mess of C++. There are problems with Java's approach, but
it works most of the time.
\_ this is factually correct but is not the right answer because
it does not address the question. the other reponses do. dork.
\_ Well... How do the previous responses address the difference
between abstract class foo { abstract int bar(); } and
interface foo { int bar(); } ? Multiple inheritance
is the *only* thing that you can do with interfaces and
can't do with abstract classes -- therefore the only reason
"interface" is not redundant. So either you have no clue or
you are a dork -- pick at least one.
\_ Who cares? It's a still-born language.
\_right, with hundred of millions of dollars of engineering
efforts using it. by comparison, you're stillborn.
\_ "Everyone else is using Win95 so it must be good!"
\_it's an argument proving it's not stillborn,
not that it's a good language. (which it is,
for some purposes)
\_ why can't motd posters use intelligent, logical rhetoric instead of
meaningless personal attacks? dumb fucks.
\_ shut up, ilya. |

1/8 http://www.salon.com/tech/col/garf/2001/01/08/bad_java/index.html \_ most of his complaints are not Java-specific. He's a bigot. \_ I'm confused. How did Salon end up with a good article online? \_ it's not so good. The author is a M$ bigot and doesn't address the large Linux solution space that uses Java on the server side. See also apache/tomcat. \_ Do you have any clue who the author is? Ever see a copy of O'Reilley's Unix Security Handbook? Try doing a search for him on Amazon before labeling him an ignorant M$ bigot. \_ I would believe the "compiled vs. interpreted" argument more if everyone agreed Perl was slow. \_ Perl is *dog* slow. No one uses Perl for speed of execution. People use Perl for speed of development and _usually_ easily \_ What is TTM? modified code. -Paid to Perl \_ Perl is painfully slow for any of the many complex tasks it wasn't designed for. For string manipultion and the like, yes it is pretty damn blazing, but for, for instance, general math it sucks crustry ass. \_ Using perl will help you learn regex a lot easier. But once you know how regex works, it's easy to start using regex package in c. \_ of course that would be missing the point. If what you want to do is string manipulation use perl. It will be fast, the code will be quick to write and relativly bug free in a much shorter time frame. Regexp package or not C is not a language thatm akes strings easy to muck with. \_ Java sucks for clients. A large percentage of Java programmers already accept this (it sucks for so many reasons), but Java is the de-facto standard for eCommerce sites and many other server software companies because you gain in TTM and OO-ness. Also, it's good for things like build scripts that need to be cross platform (which is one of many uses of Java at Oracle). \_ What is TTM? Never heard of it. Is it important? \_ time to market. \_ Bullshit. OO-ness is and of itself has no value. Stop the hype! TTM? Again, bullshit. You want TTM? Hire competent coders, not Java coders. I'll take five experienced C coders over your five Java-is-OO-TTM-kewl-but-never-did-C kids for my project anyday. Out here in the world, we want things to work and hit milestones, we don't care that BH thinks OO is "way kewl!". \_ java as a language is GREAT for clients. The problem is that the runtimes are rather lacking. eg: no-one told these VM writers how to optimize for RAM usage. \_ maybe if there was more money in writing these VM's they'd give a fuck. \_ They should do it for the love of java. Hey are these VM's written in Java? |

1/5 What's the JDK equivalent of chdir() ?
\_ You can use JNDI, which has support for directory structures.
May or may not be relevant.
\_ None, not cross-platform. There are workarounds mostly app hacking
or shell script hacking.
\_ JNI call to a script that does chdir()?
\_ Current directory is process specific, so if you spawn
another process with the script it won't help you at all.
You can call chdir() in JNI method -- it might work (dunno
if some Java libraries cache the value of the current
directory though). Why do you need it, anyway?
\_ Use java.io.File. File.isDirectory () tells you if the file is
a directory. From there, you can do things like File.listFiles (),
but make sure you do things like File.canRead () and so forth in
advance. |

\_ Possible? May be. Should you do it? No.

Berkeley. Note how the prof must spend 5 slides on talking about
"academic honesty". Great learning environment at UCLA I see.
Go ahead and try it, half the students drop within a couple weeks.

12/21 Turns out that I got a lower grade than I expected. If enough people
in the class ask for a recount (all the grades), will it help? Has it
ever happened before?
\_ This doesn't fall under the jurisdiction of the Florida Supreme
Court, but then again, that never stopped them before. Go for it!
Every grade must count! Count all the grades! Even the smudge you
made on the paper in the place where the correct answer might have
been implies you had "student-intent" to fill in the correct answer.
\_ i had a teacher in hs who used to drink wine while he was grading
and get really wasted. sometimes he would only grade half the
exam and you would get a 20 out of 100 or something, and demand
a recount and get a 90. suprisingly, he was a really good
teacher otherwise.

consistently gives too many bad grades, he will get in trouble

90's.)

really awful in math.

\_ As I recall, he was still allowed to teach but was no longer
allowed to have any part in the grading process including
setting the standards, creating the curve, grade appeals,
etc. That was all given to his head TA. Me? I was there
for 10 minutes of lecture 1 and walked out. I knew what I

12/7 How many people cheated in 162 and got caught?
\_ A little worried about our 162 grade, eh?
\_ Man, people who get caught cheating just haven't gotten the art
of it down. Should've been practicing and perfecting it in high
school (not that you needed to cheat in HS)
\_ I'm not sure how one would beat a histogram-cheat-detection
scheme. Anyone have any ideas? Other than rearranging
lots of code. And if you do that, why not just do the
project? --PeterM
\_ how does a histogram-cheat-detection scheme work?
\_ I'm not sure, exactly. This is how I imagine it works:
do "wordcount" on all the symbols in the program.
Then you sort the symbols in order of number of
occurrences. Plot a graph of this. Programs
which have just had one symbol substituted for
another will have identical graphs. --PeterM
\_ Hmm, that's easy to break. Just introduce a lot
of redundant local variables with different names
in many routines. Also, rename your local vars
"i" in all routines to "n" for some routine and
"x" for other routines.
\_ Uh huh. What if I look at keywords too?
A histogram of those. Now you have to
rearrange all the control structures too.
This is beginning to sound like a lot of
work: you'd have to do all this rearranging
and substituting and test the result.
--PeterM
\_ just make sure you send the code through
a preprocessor first, to make sure the
keywords aren't being substituted with
#defines
\_ This only breaks one histogram method. There
are probably multiple ones used.
\_ Call graph topology comparison
\_ I suspect that any kind of polynomial time
code comparison program could be defeated
without much trouble. I say this because of various
results in complexity theory about determining
equivalence. For example, determining equivalence of
Turning Machines or Context Free Grammers is
undecidable. Determining equivalence of regular
expressions (or finite automata) is PSPACE-complete.
(Recall that PSPACE is a harder class than NP).
Since programs running on regular computers
(not Turing Machines) are actually finite automata,
if you come up with an algorithm to efficiently compare
programs then you can solve a hell of a lot of other
more important problems. In practice, you can probably
defeat most program comparison tools by writing an
obfuscator program. One possible obfuscation
technique would be to merge and expand functions in a
random manner, and then randomly rename all symbols
including the function names. Of course, cheating
is unethical, but the comparison problem is an
interesting thing to think about. -emin
\_ as mentioned below, one would probably focus
on heuristics that work on typical undergrad-
LOT of results out there, and even if you CAN cheat
a finite-dimensional analysis of infinite-dimensional
spectra, it's extremely difficult to do so if you
don't know which dimensions they are looking at.
While MOSS may not be all that great, it's
presumably non-trivial. Listen to peterm above, he's
basically right. Oh, and another thing -- the class
of all poly-time code comparisons is way too huge and
it should be relatively trivial to prove that not
only is it not "easy" to defeat a random sample of N
poly-time tests if you don't know which ones they are

generated, human-readable code. further, it is
likely one would need to convert to an abstract
normal-form that is easily compared to check
the N-way cheating problem efficiently.
\_ What 172 fails to mention is the practical
inapplicability of most of these results. There are a
LOT of heuristics out there, and even if you CAN
cheat a finite-dimensional analysis of
infinite-dimensional spectra, it's extremely
difficult to do so if you don't know which dimensions
they are looking at. While MOSS may not be all that
great, it's presumably non-trivial. Listen to peterm

\_ What emin means to say is, "The cheat program is a
crock of shit. It's just a slightly improved
version of 'diff' so don't let it bug-a-boo you."
They've been talking about their mythical anti-cheat
program for years but I've turned in tons of out
right stolen code with no changes and got good
grades.
\_ you are a hollow man. You also are lucky:
the methods described above are capable of
catching THAT. Your empty mind will betray
you when you meet real challenges, and
your luck will fail.
\_ Luck? I grabeed shit off the printer and out
the trash, retyped, turned in. A. Did it
plenty of times. I could do the work, I just
didn't feel like wasting my time on it. I
went drinking and got laid. What were you
doing in the lab all night?
\_ Uh huh, and if you'd been caught, you'd
be expelled and getting your
degree from DeVry. Luck. And lazy-ass
readers/Profs.
\_ Unfortunately, the way the
work structure operates, you
can cheat your way through
the cs program at Berkeley
and yet get by in the real
world with at least a $50K
salary or even better. I opted
to get out rather than live
the lie. Some people don't
have those compunctions, but
who knows? Maybe they'll get
what's coming to them, and maybe
they won't.
\_ People have gotten caught cheating
but they didnt get expelled. it's
usually a big empty threat.
\_ depends on what they're caught
cheating on, and how many past
offenses they've had.
\_ Yes, of course the worst
offenders get booted. I did
not say nobody gets expelled
but usually it's a big
empty threat. MOST cheaters
do not even get an F for
it.
the course. This is far
different from being exiled
to DeVry for being caught.
\_ and would this obfuscator be able to produce
human-readable code? if a person spent even a
small amount of time looking at it, wouldn't it be
pretty apparent that the variable and function
names make no sense? (I guess the obfuscator
could use a thesaurus and randomly pick synonyms,
but I doubt that'd produce reasonably
intelligible results either.)
\_ This requires that someone actually look at
the code. Lazy readers and profs permitted the
cheater above to get by. No cheat-detection
method has a chance of working if it is not
applied, the common case, I imagine. -PeterM
\_ obviously, but I meant that machine-obfuscated
code should be pretty easy to recognize, even
if a reader only spends a minute looking at
it. Is a minute too much to ask for?

"yes".) |

11/30 In java, if int a=10 and:
a) a = a + a++;
b) a = a++ + a;
The result of a and b SHOULD be the same, but are not. What's up?
\_ Think about it, its not always going to be the same. Mostly
likely it will be similar to the following:
a) 1. fetch value from addr of a and store in reg 1
2. fetch value from addr of a and store in reg 2
3. increment value stored at addr of a
4. add reg1 and reg2 and store at addr of a
-> a is 20 (10 + 10)
b) 1. fetch value from addr of a and store in reg 1
2. increment value stored at addr of a
3. fetch value from addr of a and store in reg 2
4. add reg1 and re2 and store at addr of a
-> a is 21 (10 + 11)
\_ The ++ is executed immediately after its original value is used?
a) a = 10 + 10 (a now = 11, but very temporarily)
b) a = 10 + 11
\_ This is correct: Java (unlike C or C++) specifies that the
increment happens immediately after its value is used.
\_ Whoever writes code like this that relies on the implementation
of execution order should be shot.
\_ Um, there is only one possible execution order for the code
given above according to the rules of precedence.
\_ Oh yeah? Just for "a = a + a++" alone I can get two
different results:
\_ Those results (and more) are both valid in C++, but
in Java only the second can happen.
1) Fetch value of "a" on the left of '+', 10.
Fetch value of "a++" on the right of '+', 10.
Do increment for "a++". "a" becomes 11.
Write result of addition to "a". "a" becomes 20.
2) Fetch value of "a" on the right of '+', 10.
Do increment for "a++". "a" becomes 11.
Fetch value of "a" on the left of '+', 11.
Write results of addition to "a". "a" becomes 21.
\_ I did not say that a and b are equivalent. I
said that there is only one possible order of
execution based on the rules of precedence.
\_ I guess this falls under the part of the ANSI C spec.
that says that the order of execution of subexpressions
in an expression is implementation defined. I suppose
the following would be possible as well:
incr a, fetch a, fetch a, store a -> a = 22
\_ Oh, you can write code that is independent of execution order?
You rule.
\_ No, but I can write code that only relies on execution order
that is implementation-indepedent. E.g. I can write C code
like "if (foo() || bar()) {......}" and rely on the fact
that foo() is executed before bar(). But I won't write code
like "baz(bar(), foo());" and assume that foo() is always
executed before bar().
\_ Wanna really have fun? Run this in C, using native compiler,
gcc, and others and you'll get a DIFFERENT result. TRY IT!!!
\_ Okay, I don't see how a and b can ever be the same. You
are asking for two different actions to be performed.
\_ Ok, I just tried it on a sun box with gcc. the answer is 11 in
both cases. How can this be? |

\_ Sorry to say but its your fault for taking it with him and
not with Hilfinger and Java... that's what I did and the

\_ Frankly, "wrote a java compiler" looks infinitely better on
a resume than "wrote a COOL compiler".

\_ If you're hiring java engineers, would you rather hire
someone who implemented a "java" compiler or a "COOL"
compiler? Gotta take this class anyway, might as well
get the best buck for it.
\_ Yeah, there were so many cases to cover with semantic
analysis. Ridiculous for a class project.
\_ It was 10x worse with Hilfinger, so shut the fuck up.
\_ But think about how much more you learned! You don't need
a high GPA, just a sense of personal satisfaction!

it wasn't that bad if you put in your 100 hours...
I was just noting that it was way more work than Aiken's

11/23 Ok, we know that to implement OOP methods you have these nifty
virtual function tables which are assigned and thus have supposedly
independent namespaces. How are protected variables implemented in
Java or C+?
\_ same was public members are implemented. protection comes in
the early stages of compilation. by the time you get to code
generation, that information is not relevant.
\_ not strictly true for Java (access control is verified by JVM).
But generally right -- access control is a compile-time issue.
\_ typechecking by the JVM can be subverted by writing your
own classloader in bytecode; i'm just trying to figure out
why the "checks" don't work in java.
\_ Ok, I think I understand now. "protected" in Java is
slightly differrent then protected in C++ -- it also
allows access by the classes from the same package
(like default access). Why? I don't know -- ask th
people who wrote the JLS. But it makes for an annoying
interview question. ;)
\_ One that you'd get wrong. You describe the default
access control, which does not have a keyword.
\_ Default access control in java is the same as that
specified by the 'protected' keyword.
As for runtime control -- it's disabled by default for
local classes, you need to run java -verify to explicitly
enable it. I don't think writing your own classloader
will help subvert verification (otherwise it would be a
huge hole in the security model).
\_ Dude. Neither C++ nor java have true 'security.' In
correctly (use doPrivileged())
C++ you get around it by casting, in java you get around
it by using reflection. At any rate, I haven't seen a
language that enforces variable privacy.
\_ Uh, reflection actually DOES enforce variable
privacy policy in 1.1 and I think in 1.2, which
is actually a royal PITA since you want that
interface to build development tools.
\_ Not in Java 1.2 and higher if you write your code
correctly (use doPrivileged() together with
a security policy) |

11/21 All java class inherites from class *Object*, if I have three classes
A, B, and C all have one same method showErr(). If I want to have a
function that can call showErr() depending on the object that I passed
in, eg.
public void handleErr(Object o) {
o.showErr();

This code won't compile because Object doesn't have method showErr();

don't the object type at compile time. I don't think c/c++ can do th\
It works fine in C++: _/
template<typename T> void handleErr(T *object) {
object->showErr();
}
You don't need to create an interface, and you don't
need to use run-time type checking; it just works.
In Java, there's Object.getClass(), however I don't think it'll help
here...Does anyone know if the above code can be tweaked to work?

you can be more hacker style with instanceof and casting.

it saved my ass b/c without it, I wouldn't have passed

after that for my own good. I have no compunctions about this

D and have to go through the whole debacle again. That was the
one and only time I did and I will forever relieved that I did.
\_ How the hell can you get anything but an A/A+ in the class?
\_ Cheating is so easy. Look over someone's shoulders during an
exam. Sit in a corner where you're least likely to be noticed
reading a cheatsheet under your calculator. Sift thru the
recycle bins for discarded printouts of code. Share.
\_ Actually, I've seen the guys with 48gs just scan the
relavent info into their computers and upload it to

at some odd disadvantage to "those evil white rich guys!"

my lament simply was that if we were all rich we could
have a bunch of toys to play with instead of studying.
I have never envied rich people, in fact I feel sorry
for people who have to rely on wealth to get them
through life, I will always have an advantage over them.
\_ Keep telling yourself that.

to shake you down for a good grade. Don't tell your SO.

offered me anything to improve their grades. Not even the
ugly ones. And I would have gone for the ugly ones.

anti-cheat code-checking program.
\_ um, it doesn't work all that well :) It's a device of
intimidation but nothing else. I got away in 3 of my
upper div classes including his.
\_ It depends on what the definition of 'is' is.
\_ i cheated on some math tests because they didn't allow us cheat
sheets and i thought it was stupid to spend my time memorizing
a list of equations.

\_ If your symbol is the field "numPoints", the the token is an
Identifier and the lexeme is the string "numPoints". For "123"
the token is Integer and the lexeme is the value "123". In
short, token = type, lexeme = value. If you call "if" a token,
then the lexeme is redundant because the lexeme is just the
name of the token. But if you lump if, while, else, etc. into
the Keyword token (or token class, if you prefer), then the
lexeme becomes relevant. |

know that have a love of computer science started with HyperCard.
I've also seen a correlation between having clue now, and using
HyperCard when young. Obviously I'm not implying that HyperCard
bestows clue and a love of CS. More likely, it offers a fun
love of computer science as a discipline
way for people to learn a programming mindset. -dans

love of computer science as a discipline [motd formatting god]
\_ Python or pascal.
\_ Lemme explain about python: python is scripting
(immediate feedback, no compile) very clean of syntax,
and very powerful. Its only annoyance is that it requires
proper whitespacing, but it's good to learn proper indenting in
a first language anyway. If you don't know python, learn it
THEN teach it to your cousin.
\_ Python is Perl's poor cousin. Python is still longing
to be what Perl was back in version 3.0
\_ But it does *look* nicer on a printed page. :-)
\_ korn shell
I'm NOT KIDDING!!! It's simple to start, but has a LOT of
features. Functions, vars, lots of optional odd tricks.
\_ David Korn is a prick, I refuse to use his shell. Either
Bourne shell or BASH.
\_ so is RMS. So do you refuse to use gcc, emacs, or any
other of his stuff?
\_ RMS isn't as much of a prick as DK. DK's great
contribution was /bin/ksh and he goes around
like he invented computing (just like Al Bore
invented the internet). Without K&R,SRB,KT,BJ
DK wouldn't have amounted to a hill of beans.
The other thing is that he's also in bed with
M$.
\_ So what? If the technology is good, use it. Do
you not surf websites backed by Oracle because Larry
Ellison is a prick too? You're being an idiot.
\_ I don't use ksh mostly because there are just
so many other better alternatives. The fact
that DK is a prick doesn't make me want to
use it either.
\_ name 3, "so many others".
Perl is great if you want to
access a database or do network stuff,
but otherwise it's mostly overkill.
\_ Bourne Shell, BASH, Perl, Awk, Sed,
C, C++, TCL/TK, Java, Fortran, PL/1,
ALGOL, Basic, even DOSHELL! Ksh is
just a copy of SRB and BJ's work.
\_ Java is probably better; LISP may be best for a CS student to start
from, but it doesn't yield "pretty" results immediately. OOP has
a more tangible link to the real world (ie "objects and their
interaction"). More than one language at a time should be absolutely
out of the question. You will confuse the fuck out him/her.
\_ LISP is object oriented, and in fact had objects before Java.
At any rate, most modern languages provide a way to program with
objects or object like entities (with the only 2 notable
exceptions being C, which is too low level to have objects as
anything else but gobs of memory, and prolog, which can be
used to implement any object system of your choice trivially).
\_ Don't confuse what's "formally" there with what the language
was built for. If you think the CLOS is intuitive to the
average 10-year-old (relative to Java, that is), you need
serious help. All alternatives to CLOS that I've seen are
no better. Think Intuitiveness.
\_ C-like syntax isn't intuitive. In actuality, scheme's
syntax is far cleaner, and CLOS is a far better object
system than java's if for no other reason than because
classes are first class objects themselves. Want to teach
java's alternative (reflection) to a newbie? And drop this
lecturing tone, you haven't gotten enough clue to assume it
yet.
\_ Listen buddy. I've probably taught Java to more
10-year-olds than you've met in your life. And I've
tried the alternatives. If you don't believe what I am
saying, go find a sample of a few 10-year-olds and see
how you fare with your lisp fantasies. I have the utmost
respect for {lisp,scheme,yermom}, but none of them are
suitable for 10-year-olds.
\_ Which alternatives have you tried? See, friend,
you are something people in the know like to call
'Java-drone.' Would you like to guess why?
\_ Read first before spewing garbage. I don't
endorse Java as The Best And Last Real Programming
Language. As a matter of fact, I think little to
none commercial-grade code should be in Java.
Getting 10-year-olds interested is an entirely
different story. As for the alternatives --
I've tried Scheme, C, BASIC several times, and
perl, lisp, linkway (bad hypercard clone),
turing, and some obscure ancient shit you've
never heard of a couple of times
\_ What about my favorite language, assembly? *ducks*
\_ i learned to program in 6502 assembler when i was 10.
\_ m68k assembler @ age 12.
\_ 4004 at age 17.
\_ eniac circuit codes at age 5
\_ babbage gears @ age 4
\_ trained the wet-nurse @ age 6 mos.
\_ I think alot of people in our CS dept (well... at least Harvey
and Clancy) would say to teach Logo with the intention of quickly
transitioning to something more practical. I think Java would be
a good start in that it is really powerful with all the hard stuff
abstracted away... and thus can yield some rewarding results for
a 10-year-old failry quickly.
\_ If you want to hook someone on programming, you really cant
beat "Hey, I make make funny colored shapes in 30 seconds".
Logo rules for bringing them in.
(then when they're hooked, we move them up to the heavier
stuff. And THEN we start ch... Ummmm.. forget that last bit)
\_ I'd suggest teaching Smalltalk. That's what it was made for,
after all.
\_ So what? Doesn't mean it's any good for that.
\_ But it actually was a good teaching language. Supposedly
they were getting 9-12 year olds programming things like
paint programs pretty quickly with Smalltalk.
\_ The first language I learned to program in was BASIC. Even
though I liked programming, BASIC was annoying because there
were lots of strange syntax rules you had to remember. Based
on this experience I would recommend starting with a language
that has a simple, clean, and consistent syntax. LISP and Tcl
are 2 good examples. I've never used python, but I suspect that
the idea of using white space to indicate scope is the kind of
thing that would scar a young programmer for life. As for C, C++
and Java, all I can say is that if decent programmers find things
like x <<= y ^ *x++ && 0x32 hard to undrstand, think how a kid
would feel. Good luck, and let us know how things go. -emin

lighter one.
\_ Wrong. Please try again.
\_ No you are wrong. Assuming it isn't #13 when you weigh

defining a ClassA with a member variable that is a pointer to an
object of ClassB, and also defining ClassB with a member variable that
is pointer to an object of ClassA. If it is allowed, how do I go
about with the #include, #ifndef, etc.
\_ not to forget to mention that many data-structs use this
circular pointer of classes of different types (red-black trees)
so it wouldn't make sense to design one of the most versatile
languages without this feature.
\_ Yes, it's allowed. You need to do a forward declaration for the
classes that haven't been defined at the point where you're using
them. For example:
// A.h
class ClassB;
No preprocessor pain is necessary. This works for reference members
as well. And they don't have to be in separate files.... This works
too:
class ClassA { ClassB *pB; };
// B.h
class ClassA;
Good luck... -mogul
class ClassB { ClassA *pA; };
No preprocessor pain is necessary. This works for reference
members as well. And they don't have to be in separate files....
This works too:
class ClassB;
class ClassA { ClassB *pB; };
class ClassB { ClassA *pA; };
Good luck... and sign your frickin' name, punk! -mogul
\_ Hehehe! Thanks for the answer! It's kind of embarassing
to put my name when it's such a dumb question. I know
there is function declaration, but didn't know about
class declaration, having always used the #include, #ifndef
stuff.
\_ real men use "typename" for forward decls. or something. -ali
\_ Whatever. Real men know when to use typename. And that's in
template functions and classes when the type name might not be
easily derived as such.
\_ real men use real languages that don't have this sort of BS. |

do which profs use? thanks.
\_ I took cs188 from Stuart Russell, and enjoyed it. It was a
reasonably easy course, as far as upper division CS courses go.
As always, the truly interesting stuff is only covered in
graduate classes. Russell had people programming in lisp, but I
heard he is moving to Java now. Malik (who is a vision guy)
has people using Matlab. I recommend Russell. -- ilyas

most people do their projects in Java. 170 - demmel didn't like
java and told people not to use it. solutions in Standard ML were
provided. our project was written in C. 172 - no programming req'd
but I sometimes hacked together programs to do my HW in scheme
and perl. 174 - none 182 - java and (maybe?) CL 184 - c/c++/Tcl(?)

\_ If Berkeley is really serious about hard core computer
science, it would be teaching pseudo academia language that has
absolutely no revelance in the real world (just look at Stanfurd
and MIT). On the other hand, if Berkeley is really serious about
kewl language, it would be teaching Java and nothing else
(just look at community college). IMHO, Berkeley is in between
the useless theoretical academia (Stanfurd) and the ludicrous
industry (community college).
\_ Because Berkeley and MIT are so academically oriented makes
it a very good school for people who want to go out into
the real world. That's why so many good companies that make
leading edge products seek students from universities like
Berkeley. All this theory that you consider so bullshit is
probably more applicable to the real world than anything you
get out of a piece of shit trade school like ITT. I bet you
haven't realized it by now but some of the "bad-ass" chips
sitting in your computer and cell phones wouldn't be there
were it not for masters and PhD students. They don't hire
weenie ass B.S. students like yourself to do something
that important.
\_ Just to name a few:
Kahan (current Berkeley prof) - responsible for IEEE 754
standard and all FP arithmetic on Intels before Pentium
D Patterson (also Cal prof) - RISC, RAID, NOW, IRAM
D Ditzel (Cal masters, auth famous RISC paper w/ Patterson)
responsible for 20 successful chip designs. Now CEO of
Transmeta
Douglas W Clark (prof at Princeton) - lead VAX engineer
that important. Next time you go to a job interview tell
your job interviewer that you think that all professors
from Berkeley are full of shit because they're "theoretical"
and don't use Java and see how far you'll get.
\_ No C++ in 61c, mainly MIPS assembly and a little C
\_ when I was TA'ing last summer, we allowed C++ whenever we
didn't care about their being able to compile-by-hand; C
otherwise. -brg
\_ Sigh... More of the "let's use the kewlest new fad language" from
Cal profs trying to be compu-hip.
\_ clueP? Do you know what you're talking about?
\_ Do you? More code continues to be written in C than JAVA
and this will remain true for years to come.
\_ Good, that's a sensible reason to teach C over Java.
However, this sense is not evident in the initial
comment which presumes idiot profs.
\_ No. Not idiot. Compu-hip kewl profs tagging along
on the latest bandwagon so they won't look like the
dinosaurs they are.
\_ There you go again -- your point is made
\_ And how much code is written in scheme? Why does 61a
use scheme, then? I think it's because it's a good
language to teach concepts of computer science, not
because it's a good language for engineers to use in
a business environment. What do you think?
\_ Yes, true. Fine for a first class. What the hell
is the point of Java other than "We be hip! We be
kewl! We be da with-it Cal Profs!"?
\_ The move to java has let instructors focus less on learning
language specifics and more on theory. There are projects
in 61b that would have never been attempted were it still taught
using c++. That being said, it is true that students tend to
not to pick up c/c++ on their own well enough for upper division
coursework.
\_ In other words, the lower div java crap isn't preparing kids
for what they really need to know to get through the upper
div work? Kewl >> Value in Berkeley CS. Java should be a
9 series course for those interested in fads and nothing
more.
\_ I seriously doubt that the lower division work in any
form ever really prepared students for the amount of
work and "experience" required for upper division work.
The current situation merely stops making pretenses at
trying to say that these courses are "all a CS student
will need" to make it through upper division work, stop
wasting time teaching students something they should
pick up on their own, and use the time to teach them
something they won't pick up on their own. No 61x class
can teach a student the language/programming skills
they need to finish CS1xx work here.
\_ I agree strongly. In addition to providing a strong
theoretical background, I think the most important
thing Berkeley "teaches" is the ability to pick up
new languages and skills. The way this skill is
"taught" is by NOT teaching languages, and expecting
that students learn languages and some other
specifics without being spoonfed them in a class.
I will grant, however, that there are probably more
"in it for the money" lamers today than there were
five or ten years ago. The lamers don't grasp the
value of learning this stuff on their own, and want
to be spoonfed. I think the number of clued folks
has probably stayed pretty much constant over the
years, even though the number of lamers has probably
grown due to the recent tech boom. I think that the
important thing is not to lose sight of the clued
folks even though they're surrounded by a sea of
lamers. I think you'll find that they're every bit
as good as the folks of yesteryear. -dans
\_ There was a time when they knew the difference
between their, they're, and there. Looking good on

of homonyms at 3 in the morning. And for the
record: their - used for plural possession
they're - contraction, they are
there - useful little bugger, can
serve (among other things) as
a pronoun and an adverb

P.S. If that's what they teach in English 1A,
it's no wonder so many Berkeley students are
incapable of composing a coherent sentence.
\_ I was going to say Subject A but I don't

decidable by a linear-bounded turing machine, but not by a PDA.
Universal: a rule maps a string of terminals and non-terminals

Universal Rewrite Rules), decidable by a TM, but not always by

Screw this loser, read the reply after my friend:
\_ Go into it for the money. The cock suckers talking about doing it
for the love of it exist in every field. Do it for the money for
a few years so you can afford to do whatever you want for the love
of it for the rest of your life without worrying about the rent,
mortgage payments, car payments, children's educations, or how to
pay the electric bill and put food on the table. The idealists
are fools throwing away their youth. These are the same people
who will be voting every year for a socialist government to take
care of them in their old age because they "lived life for the
pure pleasure of it". They think of themselves as some sort of
counter culture heros. I think of them as leeches. Go for the
money, sonny.
\_ Hrm. I disagree with you on several points. Starving to death
so you can do something that you love is just plain silly and
as far as I can see, you're the only one suggesting such a thing.
The most common thread here is that you'll be very unhappy doing
something that you hate -- been there, done that, and it ain't
worth it. Second of all, you seem to be implying that by doing
CS for the money you will deterministically become rich and THEN
be able to go on and do something that you love. That's just
absurd. Thirdly, associating someone that enjoys their
work with a political philosophy or moral standpoint is, at
best, illogical (I myself tend to be pro-gun, pro-death
penalty -- pretty far from what most people would think of as
liberal or left-wing). You can think of them as leeches, but
if you were really *reading* anything anyone was saying, you'd
have noted that we were all talking about being *employed* and
enjoying our work. Of course, this could just be an idiotic
troll and I'm wasting my breath taking you seriously. -mice

2/11 Are most upper division courses in CS in Java? Do they teach C++/C
anymore?
\_ Computer science isn't the business of teaching C/C++ or Java
or Perl or any other programming language. Nor is it about
"how to program either". But from what I've been through
many upper div CS courses still use C/C++ including 162, 164
184 and EE 122 (yeah, it's not classified under CS but oh well).
Some like 170 let you have the option of using Java or whatever
you prefer. And 152 uses VHDL. Again, the point of the course
isn't how to program. That can easily be learned in a few weeks
and are what the CS 9x service courses are for.
\_ CS170 almost never allows Java. When did it??!? CS164 is taught
in Java once in a while. Wang let you do your 186 project in
Java if you prefer. A lot of students use Java for 169 and 160
(classes where you have a choice). 162, 170, and 184 are the
most C++ oriented. Oh ya, EE122 usually prohibits Java... at
least it has for the past 4 semesters.
\_ Java is allowed since "C is too hard... waaaah... I always
get segfaults and core dumps and don't know what it means!!"
\_ That would be a good point except for the fact that it
it isn't true. Java usually isn't allowed in CS170.
\_ Wrong. At least for the past 3 semesters, there were
no official restrictions on what language to use for
the projects.
\_ Agree.
Nuclear physics, academia = quantum mech, hardcore equations
Nuclear physics, industry = cleaning up nuclear waste
By the same token,
Computer science, academia = hardcore algorithm
Computer science, industry = debug other people's code
As usual, academia=no money=:(, industry=money=:)

undergraduate curriculum to teach people languages or how
to program, as matter of neccesity, students must learn
how to, even if they have to do it on their own.

not apply. In return you are allowed to use my software on one
computer until such time as I feel otherwise and you have no
recourse if I break your computer or the software does nothing
because the CD is a blank. You agreed to all this upon opening
the shrinkwrap. Now that you understand how a M$ EULA works,
you think it'll protect them from any lawsuits?
\_ heh it would seem that YOU don't understand much about the

\_ Well, gee, let me get out M$Calc. Do you math, idiot. And the

\_ What's the average hr per unit? # of weeks in a semester?
Should lab hours be counted?
\_ Where have you been? It's supposed to be 1 unit of
credit = 15 hours of class over 15 weeks. So a 4
unit class is 4 hours/week * 15 weeks = 60 hours.
Labs tend to fuck this up but I don't take any lab
classes so I don't care. 15 units/semester is the
standard. Where are you people getting this 14 and
16 and other crap from?
ED! ED! ED is the standard! number of units per semester _/

you end up paying about $9 per hour. Conclusion: You can

med school is a totally different story.
\_ w0w, Publik sk00l is cheap!!

including 2wks for tests) and about 6.5hrs class/day.
Therefore it is ~$7.7 per hour of lecture/lab. Include
tests, and rotations at infinite hours per week and that

\_ You can try reading the lecture notes at
http://www-inst.eecs.berkeley.edu/~ee122
but Kevin Fall was the worst professor (if that's what you call
him) I've ever had at Berkeley so I don't know how much you'll
learn from that. Maybe you should buy the 122 book.
\_ Yes, he was the worst prof ever. But he didn't give any grade
below a C-, even if you didn't take the final.
\_ Worse than Alan Smith?
\_ I know this 4.0gpa, 17 A-pluses guy who thinks Alan
Smith's class is great.
\_ You can't???
\_ Well, if your primary interest is continuing your string
of A-pluses, rather than learning something, Smith *is*
\_ Learning is worthless if you can't show it off with
good grades. If you're not getting good grades,
you're wasting your time in school. There's very
little you can learn in school that can't be learned
out of school. The only difference is good grades
are evidence of having learned something. A big
"yeah whatever, go fuck yourself" for anyone who
brings up the old line about not wanting to work
for anyone who would dare be stupid enough to ask
your gpa. That's just sour grapes.
\_ Not true. By example, I have two friends in
CS. One has a 3.8 and the other has a 3.1.
\_ I took that ee122 w/ kfall. I rather liked the project.
It wasn't a standard Berkeley CS "Fill in your code here"
project. It was: read the rfc, write code according to
SPEC. This made me actually feel like I was doing something
useful. I still use and am developing my webserver today.
My only gripe was that the lecture notes were in a format
(converted .ppt -> .ps) which took too long to print - paolo
\_ And then there are those idiots who think they can print
PDF files straight to a postscript printer.
\_ You can't???
It's pretty amazing how someone with a 3.8
can ask some of the stupidest questions in
the world but I personally wouldn't trust
my life to him. He once asked me if you
could cast an Integer in Java to a string by
Integer i = new Integer(5);
System.out.println((String)i);
How pathetic, yet he still has a 3.8.
The guy with the 3.1, on the other hand, is
a hell of a lot more trustworthy as he
doesn't do idiotic things like cast Integer's
to String's
great for 162 . . . just memorize his lectures so that
you can regurgitate them back at exam time, and you'll do
fine. Not to mention that you didn't have to spend too
much time on those pesky NACHOS projects, because they
were worth practically nothing.
\_ He buys Smith's argument that for cs162 class
projects, simulation is more useful than synthesis
(ie. NACHOS) in the "real world".
\_ "Real world" arguments concerning Smith would have
been convincing if he didn't spend his lectures
reminiscing about paging out to drum memory on his
IBM 1401 . . . for him, the real world stopped
somewhere around 1972.
\_ Dude, you could've taken 122 from Jean Walrand. Count your
blessings.
\_ http://www.cisco.com
\_ Cisco has a CD set they give out at their courses. It's pretty
good if you ignore the marketing garbage and product info on it.
Mine's marked "Sales Order Number DOC-CONDOCCD" if that's any
help. -John
\_ Still think that kfall wasn't that bad, even if you selectively
edit this file. the webserver project was good, it wasn't an
"insert code here" type of project, it had to be written from
scratch to the rfc 1945 spec. If you want a good book, DO NOT
BUY Peterson & Davie, kfall himself recommended a book by Keshav.
- paolo
\_ i think the only good criticism of the class was not that kfall
assigned real programming projects but that he wasnt upfront
about it at the beginning of the semester. The class had
not previously had as involved a programming project as when he
taught it and such could not be expected from the catalog.
Really, though, there should be an ee122 and cs122, with some
common ground between the two. ee122 should talk about the
the hardware implications of a network protocol and how that
affects protocol stack design and cs122, the design of a
protocol stack and use in applications. But as ee122 talks
about both aspects, yes, students should be prepared to
implement a real network protocol. And for the original
question, TCP Illustrated. RIP WR Stevens.
\_ NO!. I will explain: if the Networking class was a CS
class, I could not have taken it last semester. Same with
_EE_ 150. CS Classes are restricted, thus ensuring
high wages for those who can graduate with the major.
(not necessarily high clue.) - paolo
\_ paolo, that is a selfish attitude. just because you
might not have been able to get into the class doesnt
mean that it should be taught in an ineffective manner.
If separating ee122 into hw and sw classes would teach
the material better then so be it.
\_ Dreamer. It's all about self. School has nothing to
do with The Right Thing or they would make sure they
didn't have to restrict classes in the first place.
Check out the forest, not the trees.
\_ right, and so you can have upper div cs classes

THE SIGNIFICANCE OF TUPAC SHAKUR
Ethnic Studies 98, 2 units, MW 12-1, 155 Kroeber
Tupac Shakur made a significant impact on current and
future generations.
This class will explore the nature of Tupac's significance. Class
discussions, analysis of poetry and songs, guest speakers, films, and
literature will be utilized to accomplish this exploration.
Course Coordinator(s): Felipe Macay, lipo24@excite.com, 636-1995
\_ This isn't real. You can't earn credits for this. Please tell me
this is a joke you made up and not from the class catalog.
\_ This should satisfy the L&S philosophy & values requirement
since all of those classes are detached from reality.
\_ this _is_ a class, and I am taking it - for the units of course.
and the large reader is _quite_ humourous.
\_ If you do take this class tell us what the makeup of the
class is. I bet you there's a bunch of whore chicks
dressed in nasty clothes and guys who shave the sides of
their heads but let their tops grow out really long,
wear their visors upside down and backwards, Tommy
Hilfiger shirts and stupid frat jackets, and baggy pants so
baggy that you need rubber bands, and drive stupid suped up
Honda Civics that don't do anything but scrape the ground
and vibrate
\_ I once saw an MTV "News Report" saying that Tupac Shakur's
death is the most important event in the 1990's. Now, if
that isn't intelligent journalism then I don't know what
is. I once associated myself with the MTV generation.
Now I'm just ashamed to even know about it. Unfortunately,
half the dumbshits in this school think that the entire
world revolves around (c)rap.
\_ I'm not the world's biggest rap music fan, but how do
you get off saying something like this? it is the most
powerful influence in youth culture in America, with
the possible exception of religion. So what do you
think the world revolves around? c++? Britney Spears?
William Faulkner?
\_ I didn't say it revolved around anything. But in
a decade when we've seen Yitsak Rabin, Mark
McGuire, John Glenn, and many world leaders make
history, and massive world events like the Balkan
conflict how can you say the Tupac's death is
"the major historical turning point in the 1990's"?
\_ Mark McGuire? this is a joke, right? and what
kind of history has Glenn made this decade?
being an old man in the middle of a public
relations stunt?
\_ Oh yeah, and Tupac is something I want my
kids to remember about the 1990's. In our
US History books twenty years later we'll
have "Tupac Shakur's death throws America
into turmoil" instead of "Mark McGuire makes
history". I hate baseball more than anyone
else but I know what's historically
significant
\_ How could you have missed the nationwide
riots that occurred as a result of Tupac
being shot?
\_ Riots because one black drug dealer was
shot by another black drug dealer?
\_ Take it or leave it, hiphop is an interesting social and
artistic phenomenon. I personally find it fascinating
that it provokes the extreme reactions in people that it
obviously does. You don't see people going out and
speaking out against the evils of broadcasting bubblegum
oldies or classical music, and the fact that gangsta rap
is both widely popular and widely reviled points out that
there are two widely-held and diametrically opposed
viewpoints on it; add in a flashy celebrity personality
such as Tupac, and you get something which could be the
makings of an excellent opportunity for bringing people who
were merely passive listeners or passively disgusted
together to talk. (I can't help but imagine that the above
poster, for one, will be in attendance in order to set
everyone straight. And of course I'm being wildly idealistic,
but if there's going to be any intellectual discussion of
ideas on this campus, it's not going to be in the stagnant
code farms of the EECS dep't.)
\_ Pfft. As if there's going to be any serious intellectual
discussion of ideas within Ethnic Studies . . . I quickly
learned that the way to an A in my Ethnic Studies class
was to *never* debate the statements of my (communist-
lesbian-of-color) TA, but to merely absorb her spouting
and regurgitate it in my next essay or exam. I sure
hope this ES98 is a DECal class . . .
\_ it's pretty sad but I think this is about the only
thing that I learned in my years at Cal -- just give
them what they want and nothing more
\_ Artistic? Yeah right. You want art and culture, try
listening to the Beatles, Simon & Garfunkel, Van
Morrison, Bob Dylan, Bob Marley, Dave Matthes, Barry
White, Mozart, swing, jazz, blues, whatever. I admit,
even I listen to bubble gum shit too but at least I admit
that the crap I listen to on the radio is bubble gum.
Rap is exactly that - bubble gum, but with minorities
dressed in flashy clothing and singing to a variation
of the same tune. It's bubble gum and it's not
something worth studying for artistic and cultural
reasons in an academic institution.
\_ we can't have a "colored" storming these ivory

8/4 If Java has no pointer, how do I create a data structure of link
list, btree, hash table+links, etc? Thanks.
\_ Because sometimes pointer means more than "reference", and the
posters below are being disingenuous or stupid (or both).
Can I create a dangling reference in java? Can I create a
reference that causes a bus error or segv? No.
\_ You're calling Hilfinger stupid? "Hashtable x;" x is
a memory location to data structure on the heap or a null
memory reference, hence the name "pointer". You can
play the name game all you want but they do the same thing.
What special precations the JVM takes is no matter to the name.
\_ There are two classes of variables in Java: the primitives (like
boolean, int, float, double, long, char,...) and pointers to
objects. It's just that in Java there are no * and & like in C.
All those symbols are implicit. You cannot have data structures
allocated on the procedure stack. All Objects and things that
derive it end up in the heap (dynamically allocated) while
primitives and pointers are on the proc stack. --jeff
\_ Objects.
\_ EVERYTHING IS A POINTER. JAVA HAS POINTERS.
\_ java has refrences you dumbass

6/27 So who is kidding who? Sun withdrew from ISO because
it did not want ISO to control Java
\_ Bottom line: Sun invented Java, Sun owns Java, end of story.
\_ That's fine. They shouldn't try to pretend it's some sort
of standard then. If they want it to be a standard, they
need to play by the rules of the standards bodies.
\_ Idiot. saying "it isn't a standard unless a 'standards body'
owns it", is like saying "It isn't software unless it
is copylefted".
\_ What part of "they own it and can do whatever they
want with it" don't you understand. It's called
intellectual property. They invented it, they own
it, it's theirs. If we didn't have this kind of system
there would be no incentive to create new things.
\_ that's nonsense. "sub-optimal incentive
according to mainstream economic models",
sure. "No incentive", no way. There
are all kinds of reasons to create new
things without exclusive govt-backed
IP rights in them; there's just an
argument that it's more "socially optimal"
to make up stuff like copyright, patents,
etc.
This isn't communism.
\_ ** Insert your bh-GNU-RMS comment here **
\_ At least RMS lives his beliefs.
\_ You didn't actually answer the previous person, who
merely said that Sun "shouldn't try to pretend it's
some sort of standard", which IS an impression that
their marketing has been conveying of late. To be
more specific about what kind of standard we're talking
about: open industry standards developed through
standards bodies or technical working groups with
some kind of open participation, public comment, or
peer review. Sure, Java is a Sun proprietary standard,
and it's cool, but it doesn't have the status of
something like TCP/IP or the SI.
\_ Of course they withdrew. Duh. What point do you think you're
making?
\_ Java to die as fast as other proprietary technology.
\_ You mean like the way all the MS crap has done so
poorly as a proprietary system from top to bottom?
Has MS ever released a single line of code for
*anything*? I want Open Bob. I had some ideas for
MSBob improvements.

6/22 How come in Java, I can do the following:
str = str + "Hello world";
instead of
str = new(str + "Hello world");
\_ Because you are not telling the new keyword
what type of class to create. The + operator
has been overloaded so that you can cat strings
together.
\_ java doesn't support operator overload
\_ It's actually a very simple modification of the parser grammar
and a few additional AST (abstract syntax tree) nodes. The two
turn out identical code anyway and is was done simple because
they can and makes it more convenient to use (though it makes
the grammar syntax less consistent).
\_ See the JLS under the section for java.lang.StringBuffer
(20.13) for how they suggest you compile the string +
operator; it's instructive even if you aren't writing a
compiler. -brg
\_ you mean "as well as", not "instead of".
Why = because programmers are lazy, and sometimes stupid.
\_ better short cut and work than longer and not works, stupid j
\_ #F, programmers, especially those in the INDUSTRY, are
always stupid. They always do short cut that work but
are lousy implementations. Then they leave the company
and the new hires get to debug their code. That is INDUSTRY
\_ shut up kchang.
\_ This is a bit unfair. Industry programmers have this thing
called a 'deadline'. They're not stupid. Apathetic and
under a lot of pressure is more like it. No more stupid
than a 'non-industry' programmer whatever that's supposed
to mean.
\_ yeah, and grad students don't have deadlines
\_ "Professor? I need a few more weeks." "Ok."
"Boss? I need a few more weeks." "Tell me
again how much I pay you?" Hardly the same.
Don't fool yourself into thinking academics
work as hard as industry folks. I've done
both for a few years each and academic work is
like being on vacation in comparison.
\_ Why is this a religious issue in the first place?
Strings are treated in Java more like base types
in the syntax even though they are instances of
the String class because of the prevalence of
Strings. One can think of them as char*. Versions
of C++
String templates offered this as an overloaded operator before
there was Java. Anyway, if you don't like overloaded operators,
don't use them. williamc

professor?

but I didn't really jive with his teaching style. When I
took 264 under Savage Sue, I felt that I was getting a
much much better experience. -blojo
\_ Seconded. Sue Graham rules.
\_ I had Sue Graham for 164 and thought she was really good.
Why do people have horror stories about her?
\_ Because she is boring. And because she generously only
takes away 3% of your grade per hour (as opposed to the
usual 5%) when she finds out cochise died 3 hours before
the project deadline. -- ilyas
\_ She isn't nearly as boring as most profs and though
yes she is though, she is at least fair, which is
yes she is tough, she is at least fair, which is
more than I can say about some others.
\_ You don't want a smart teacher. You want a good teacher. IE:
someone who can teach the material well. There's nothing in any
of those classes any of the profs teaching them shouldn't already
know sufficiently.
\_ I had him for 164 in Sp '92. His lecture wasn't exciting,
although he seemed smart. I think he gave easy grades. -- yuen
\_ Easy grades are important (not being sarcastic).
\_ yah avoid a prof who gives easy grades. His class
will probably teach you nothing.
\_ Yeah you should do what I did and take all the
really smart, hard grading profs, learn a lot, and
see your gpa drop a full point. Good idea. Tell
the corporate recruiter that your 2.8 from Cal is
the same as another Cal student's 3.8 or a Farmer's
4.0 beause you took really hard profs! Yeah right.
\_ "We have a saying at Berkeley: 'If they want
to know your GPA you don't want to work for
them.'" My advice is go to a few interviews
for jobs you don't want sometime when you
aren't obviously hungry to practice being
a bit cocky. Sure some interviewers will
gag and not want you, but you didn't want
that job. In the long run you will find
yourself doing more interesting work for
more pay.
\_ Yup. That's exactly what I did. Why?
Because I didn't have the gpa for grad school.
Thanks for the tip.
\_ I gotta admit under a 3.0 is pretty
sad. (Which is what you need to get
over the grad school cut) Hell even
I managed that.
\_ You didn't take all the harder teachers
like I did and learn as much as me.
As I said before, take easy teachers,
get a good gpa. The rest is bullshit.
Don't fall for the idealism crap about
learning more.
\_ oh i didn't realize you knew
what classes I took. Sorry.
(As a matter of fact I tried to
avoid the easy classes cause I was
here to learn. I'm just saying
a 3.0 really isn't that hard to get,
at least not if you consider yourself
grad student material)
\_ You wouldn't have a 3.0+ gpa if
you took all the harder classes.
Maybe you missed the basic
concept that it *isn't* easy to
get a B or higher in a hard
class. Or maybe Cal has just
watered it down in recent years
to keep the grade inflated
self-esteem raised weeny kids
of the Baby Boomers from going
off the deep end and suiciding
when they get less than a 4.0

more in his class than in any other undergrad class.

Yes, it does setup Eps 2-6 very well. I am looking forward

CS264 (Graham's graduate PL class) this semester, especially a
sylabus and what the class is covering? The department web page

\_ I took 264 and 265. They're good classes... about half of
264 dealt with basic compiler mechanics, kind of like 164,
but faster and more intelligently. The rest of 264, and
all about 265, was about optimization and code manipulation.
Very good stuff. (This was with Graham that I took them,
maybe 4-5 years ago... who knows if the classes have
changed though.) -- blojo

my research some, and our ASPLOS paper, but as for the rest,
I'm not sure what to cover. - seidl

conclude this lecture will be lame or you are trying to
show off. And that isn't an exclusive or.

getting a hold of Sue Graham is as easy as sending
her mail of any sort. And Matt Seidl hardly needs

\_ In terms of outside lectures, I remember them being
pretty free-wheeling. Just talk about what interests
you most about your current work. The class is full
of smart people, so they'll get a lot of it, and what
they won't get is still okay, because a lot of the
class is like that. -- blojo

fend off boredom). as said above, talk about your stuff

9/24 http://seanreilly.com/java/moneydance.html Quicken down, 1 less reason to use non-UNIX OSes...how many more to go? \_ Linux is pretty good for java apps because it has native processor support (kaffe) that no othe os's have. \_ what are you talking about, "native processor support"? That would normally mean "the processor natively supports java", which is obviously false. Do you mean "JIT compilation"? kaffe does that on lots of platforms. Do you mean "compiles to actual executables"? The kaffe web pages don't say it can do that, and I don't think it can. \_ there are java->native cpu compilers for other OS'es though linux loses \_ yah. What kaffe wins on will be its new awt implementation. That is, when it actually works. (it will run on DOS, though. wow. http://www.kaffe.org Do you mean "you can type the name of a java class, and it runs"? So WHAT? \_ From the RH linux package description on kaffe: "This is Kaffe, a virtula machine design to execute Java bytecode. This machine can be configured in two modes. In one it operates as a pure bytecode interpreter (not unlike Javasoft's machine); in the second mode it performs "just-in-time" code conversion from the abstract code to the host machine's native code. This will ultimately allow execution of Java code at the same spped as standard compiled code but while maintaining the advantages and flexibility of code independence." -RH linux installation guide \_ Note#1: linux was one of the LAST packages to get a JIT compiler, compared to other major platforms Note #2: THIS DOES NOT "allow execution ... at same speed" because real C code gets better optimization from the compiler. And incidentaly, kaffe supports JIT on linux, solaris, and a few other platforms. This is NOT linux-specific in any way, shape or form. \_short summary: the above linux bigot is an idiot who wouldn't know a java compiler from a hole in his head \_ this looks kinda neat :) |

My high school CS teacher had a bunch of newbie programmers
stuck in her intermediate Java class, and she's at her wit's end
trying to find good materials suitable for beginners. Thx. -anirvan
\_ Arnold & Gosling - The Java Programming Language. I thought it
was pretty good. You can't get much simpler than that. It's
also the official book on java. If they're HS students make
them suffer and teach them scheme.
\_ Just give them the grade they earn.

I asked before - How can I run afterstep on the EECS Instructional
computers, *without* installing the package etc...? I tried every
suggestion in the previous answers, but they didn't work on the
EECS computers, nor on Soda. Any ideas? Thanks, - noah
\_ there is no AS on eecs instructional. There is WindowMaker on
the Solaris machines which comes very close to AS (i actually
think it looks a bit nicer). It's a pain in the ass to install
and it
won't always work on the first try so you have to play around a
little. The install scripts are at /usr/sww/GNUstep/bin/ I
think it's called wmaker.inst but read the README). good luck
-jeff
\_ There is no AS on soda either, but it's in ports, so mail root@soda
and ask them to install it.
\_ /home/tmp is your friend.
\_ that's one of the most unreadable and unhelpful books on the
market. it's OK as a reference, don't try to learn from it.
\_ I concur. While The Red Book and The Gray Book
literally define The Java Platform, it's more useful as
an implementor's
guide than as a teaching aid. I would recommend the
Tiger book (ORA's
Java in a Nutshell). -java stud
\_ Just give them the grade they earn. HS Java is worthless anyway.
HS'ers are too stupid to learn anything anyway, why bother?
\_ I beg to differ. I learned Pascal/C in high school, and it
helped give a good head start in cs60B.
\_ Then you had a worthless 60b class. Who taught?
\_ 60B used to include teaching C, so why is it
so hard to believe learning C in advance was
a head start?
\_ Like a few of my partners who thought they
knew everything until they didn't?
\_ Maybe he just had a good HS teacher. Such things
are rumored to exist (like when BH taught HS).
\_ A myth. I refuse to believe this.
\_ good HS teachers, or BH->HS?
\_ The former. The latter isn't of
any interest but I recall him
saying something about it once.
\_ jove was written by one of
BH's HS students.

\_ Check out the research project known as "Borneo" if you need
Java + IEEE floats. It's run by the master of IEEE floats himself.
\_ Java is believed to not implement fp correctly. I believe the
most recent version has fixed this but I'm not sure. Ask your
61b prof. I think the've eliminated the 2 implicit guard and
round bits because it is a hardware implementation. ?

which is shipped with jdk1.2 beta. But I can't find this file
in my jdk1.2 beta directory...am I missing something? Should
I download the JSDK seperately?
\_ No it doesn't say that at all. You might want to re-read it again
at http://java.apache.org. Basically the mod_servlet requires JSDK but
you have get it either from JDK 1.2, or you down it as a separate
package. Btw, the latest version of JSDK is 2.0 now. -- cm1ee
\_ you can only use servlet with sun's java server or w3's jigsaw
server
\_ Not true anymore. There are now at least a dozen HTTP servers
that supports the Servlet interface. See http://jserv.javasoft.com.-cm1ee
\_ That's not what Sun claims.
http://jserv.javasoft.com/products/java-server/servlets/environments.html
\_ a "servlet" implies that the server has implemented the Servlet API
framework. Now figure the rest out.

5/8 What's the difference between a compiled language and an
interpreted language? Advantages of each?
\_ interpreted programs are executed by yet another program
(usually a compiled one) and compiled programs are completly
executed by the computer hardware (the binary is just a bunch of
machine language instructions that the processor can understand.
Compiled programs tend to be faster because of less overhead while
interpreted programs tend to be more portable. Then there are the
compiled interpeted languages like java that have both the speed
and portability advantage.
\_ What do you mean Java is compiled interpreted?
\_ Java is normally compiled into JVM bytecode, which is
interpreted on machines that don't run on Java processors
(i.e. 99.999% of computers that run Java) - it gives
portability with a speed tradeoff.
\_ Any language can be compiled or interpreted, including java. -tom

\_ programmers write code, software engineers design it
\_ so software engineer never code, and programmers never design?

if you were one of them, sign here, and we'll try to resolve this case"
Class action suits are good.

\_ Not really. It's very difficult to prove especially
on something like earnings data which can be interpreted
in different ways (e.g. a company showing record profits
might see its stock fall if earnings were not as high
as "analysts' forecasts"). Management would get in
trouble though if they purchased shares of stock knowing
that the company was going to be taken over next week and
