5/1     What's the difference between CS and Computer Engineering?
        \_ One is science and the other is engineering.
        \_ From
           'A folkloric quotation ... states that "computer science is no more
           about computers than astronomy is about telescopes."  The design
           and deployment of computers and computer systems is generally
           considered the province of disciplines other than computer science.
           For example, the study of computer hardware is usually considered
           part of computer engineering'
           Here in Cal, though, I think an EECS major is free to take a whole
           bunch of CS16x and even CS17x theory courses (maybe that's why it's
           called EECS rather than CE) while a CS major can take EE courses.
           As if it's not confusing enough already, check this out:
           BTW, another set of seeming confusing majors in Cal:
           BA Chemistry, BS Chemistry, BS Chemical Engineering.

4/02    We use Perforce at work for revision control. It seems to work okay.
        Lately, a lot of the newer developers are saying that Perforce
        sucks and we should switch to Mercurial or Git. I have done some
        searching on the Internet and some others have this opinion. Added
        advantage is that Mercurial and Git are free. However, there would
        be some work to switch for the sysadmins and the developers.
        Is it worth it or do people just like what's shiny?
        \_ I *love* git but there are good reasons to use Perforce. Do they hold
           for you?
        \_ I *love* git but there are good reasons to use Perforce. Do they
           hold for you?
           \_ That post pretty much describes my experiences with git and p4.
              Unlike the author, I do use the distributed stuff in git (it's
              nice to have a local repository when you're working from home),
              but everything else is right on.
           \_ We're moving from Perforce to Git. Too many branches and pushing
              code around is painful. Idea is to properly componentize the platform
              and apps, and have 1 repo per jar, stored our GitHub-FI. Let maven
              download the dependencies and do the build locally. We'll see...

        \_ These "new" developers want the latest and greatest. Hint. It's
           not about the language or the revision control system. It's how
           you use them. There are 10000s of ways to use Git. What is the
           convention you guys agreed on? That is more important that anything
           else. What happens if architect A wants to use convention A and
           another architect insists on using convention B and they're
           incompatible and you end up with a massively distributed unmergeable
           monster and end up bifurcating the code base? You're FUCKED!!!
           Another thing: having a code-review system is much more important
           than the revision control system. If you don't know what that is
           or understand why that is more important than language/system/platform
           then you should not be in a position to make this type of decision.
           What is your position in the company and are you in the position
           to make this type of decision?

        \_ Are any of these not born to millionaire parents?

              to find that information on Wolfram Alpha
           \_ Was Tiger Woods' dad a millionaire? Also, Sergey Brin's bio
              said his parents were a professor and a scientist while Larry
              Page's parents are both CS professors.
              \_ rising stars usually get much more help from a nice family
                 than those that came from the slums. Do you think Bill Gates
                 was born in the slums? Hell no, his family was pretty well
                 off already and that gave him a lot of freedom to do what
                 he loved doing instead of trying to work at a stinky
                 $120k/year job that can barely support a family in
                 Silicon Valley.
                 \_ Bill Gates was a trust fund kiddie. So was Donald Trump.
                    I would argue that Larry&Sergey and Tiger (certainly)
                    were not. If you hate your job and your salary then
                    do something about it. Go to medical school or go get
                    an MBA and work for Goldman Sachs or get good at golf.
                    Things could be a lot worse than making $120K before
                    age 40. That's in the top 10% of incomes. $160K puts
                    you in the top 5%.

                       kids who were raised in upper middle class families
                       and went to Stanfurd are underprivileged? You have
                       a very distorted view of the real world.
                       \_ Did I say underprivileged? More like middle
                          class, which is a far cry from being born to
                          millionaire parents.

                             or really bad with their money. I am sure they

                             most millionaires, but they are clearly quite
                             privileged. The best way to be succesful
                             in America is to be born to money.

        Ruby sucks.
        \_ Looks no different than python/perl/etc.  It's a scripting language
           that needs a virtual machine if it is ever going to be fast.  The
           scary thing is how much modern computing doesn't need stuff to
           be fast, especially when dealing with web applications.  There's
           also a big problem with that shootout; there's no concept of
           how your average coder will do in language x.  Some languages
           are amazingly powerful, and if you know what you are doing you
           can write good, terse, fast code, but if you put an average
           engineer down and teach them the language they will write
           unmaintainable garbage that noone can read (even after years
           of experiance).  That's what dependability really means.
        \_ As above, if Ruby sucks here then so do Python and Perl.

5/12    Anyone here use THE JIRA for issue tracking? How much does it suck?
        \_ Don't really use it.  Our team evaluated it and decided in
           favor of Bugzilla.  Bugzilla doesn't cost $2k--though cost
           is negligible.  The real deciding factor was that in my
           environment it can take 6 months to deply software not
           already on an 'approved' list, and Bugzilla was already
           on that list and JIRA was not.  At the time of evaluation,
           JIRA had no support for SVN interoperation, but that
           has since changed.  I realize this answer is mostly useless,
           but hey, at least someone cared.
        \_ I'm spearheading an effort to install it into our process.
           It has a lot more features than Bugzilla.  The SVN integration
           you buy with a different product, Fisheye.  The downside:
           JIRA is written in Java, and sometimes throws stack traces.
           We have yet to lose any data though.
        \_ I worked at a place that went from Bugzilla and wiki to JIRA
           and Confluence and while the transition was quite a bit of work,
           the end result justified it. Out of the box, it is as good and
           has a bunch of cool work flow stuff you can put in there to make
           you and your managers life a lot easier. Setting up the work flow
           is a big job though, so if you just want a ticket tracking system,
           I don't know why you would switch.

1/21    If I have a linked list of structs and many of those structs have
        members that are structs then what is the best way to free() the
        memory when I am done with them? I thought I would walk the list
        and do a free() on each member of each struct, but that generates
        errors like free(): invalid pointer, presumably because I don't
        always allocate memory in each struct. No, I never took a class in
        memory management (obviously). In a Java World I don't worry
        about all this! ;)
        \_ Why don't you just check the pointer before calling free? i.e.
           if (p) { free(p); }
           \_ This was my first inclination and it doesn't change anything.
           \_ This should have no effect in this case.  The if only checks if
              p is null, and if p is null, most versions of free will ignore
              p is NULL, and if p is NULL, most versions of free will ignore
              it anyway.
                   \_ All versions.  It's a requirement in the standard.
                      \_ Hah, you assume all libc implementations are
                         compliant. Well, okay, things are better these days.
              That said, if you aren't allocating the memory for the pointer,
              you NEED to set the pointer to NULL.  Preferably at the point
              that the enclosing struct is allocated.  Otherwise that pointer
              may just be nonsense, which the if won't catch.
        \_ Well, do the structs contain other structs, or pointers to other
           structs?  If struct A contains struct B, struct B is allocated
           and free'd as part of struct A.
           If struct A contains a pointer to struct B, you need to make sure
           you're allowed to free the pointer before you do, perhaps there
           are multiple pointers to B, and B shouldn't be free'd until all
           the pointers are done.
           If you are supposed to free pointer to B, but you think you might
           be accidentally freeing it twice, you're going to have to be more
           careful and figure out where exactly you should free it.  There's
           no easy way out of that.
        \_ You need to define the difference between and owning an object and
           referring to one.  It's a logical difference -- the owners are
           responsible for lifetime, referring pointers just are assigned.
        \_ You're not doing something like the following, right???

        desperation to cut costs and survive as an independent company. Sun's

        \_ As a ex-Sun employee I am not surprised. Sun has been mismanaged
           for 10+ years, and is full of deadwood and useless middle managers.
           Even this job cut won't be enough for the company to survive. Pony
           tail boy needs to reduce the work force down to about 10K and put
           an end to the java religion w/in the company is to survive in the
           long run.
        \_ As a ex-Sun employee, I think there are many reasons for Sun's
           problems.  Linux is one reason, at least in the workstation /
           low-end server market.  Intel is another reason. Sparc is just
           not all that important anymore.
           But the two biggest reasons I think are: (1) extremely poor
           management; and (2) java.  Management at the upper levels was
           always unwilling to see reality and did not make the cuts that
           were needed in the early part of this decade.  If Sun had cut
           its staff to 10K-15K in 2002-2003, they would be reasonably well
           positioned today.
           Also, Sun has way too many middle managers and upper level
           technical deadwood (architects, sr. staff eng., &c.).  This was
           a problem that management was also unwilling to correct.  These
           people are the ones that foster the java-religion w/in the
           company.  It doesn't matter how lousy a java project is, it will
           always be selected for funding over a non-java project.  In fact,
           I saw profitable non-java projects cancelled in favor of
           incomplete and unreleasable java projects.  The only reason for
           these cancellations was that the profitable projects weren't using
           \_ Religion? You mean cult.                  -I hate Java
              Cash on hand is 2B, market cap is 3B, so your first premise
              is incorrect. Also, what you should really be looking at is
              real tangable assets minus liabilities and that is even less,
              more like $1B. But JAVA really is cheap.
              \_ I disagree. Take a look at:
                 Maybe I am not reading this right, but it looks like Sun
                 has lost about $1.3 billion to date this year, and lost
                 $864 million in 2006.  This trend is not new and reflects
                 the unwillingness of Sun management to face the reality
                 that fewer and fewer customers need sparc, java, zfs, &c.
                 and that too many people are employed in developing things

                    negative hit is on sale purchase of stock, which
                    probably means they spent some cash to do a share

7/28    Python question:  I have a Python helper script/class that I want
        to use interactively.  The class needs a few path variables defined
        so that it runs on the correct files.  I may want to use different
        files, so I certainly don't want to hard code them.  There are also
        enough files that I don't want to pass them in as arguments.  I thought
        I might be able to have a file that defines them and import it.
        so, file defines "foo_path = 'blah'"
        >>> import test_config as foo_config
        >>> print foo_config.foo_path
        >>> foo_run()
        in the script file I have: print foo_config.foo_path
        I get: 'NameError: global name 'foo_config' is not defined'
        Why does my script file not get the 'global name' foo_config?
        \_ Is foo_run in a different module? Did you do something like
           'import foo_run from foo_run_module'? I'm guessing it would
           work if you imported foo_config from within foo_run_module.
           \_ Yes, that works, but I would prefer to be able to interactively
              load different modules as foo_config.

         \_ The above is pretty good.  In this case the primary difference
            is that SA is working for me and the Operations job is working
            for the Director of Operations.  The operations part requires
            more job requests from the few non-technical people we have.

5/2     I'm out of school. What's the best link to self learn stuff like
        k-means, clustering with gaussian mixtures, gaussian bayes,
        EXPECTATION MAXIMALIZATION, EM convergence, inference engine,
        classifier, desnity estimator, regressor, etc?
        \_ Start with wikipedia, follow links.
           \_ Uh, no. This is not the kind of stuff you can learn
              from wikipedia.
              \_ Take the first item.  K-means.  It described the basics
                 and had pretty informative links to outside sites.  Some
                 of those links have references to books to read/other places
                 to look.  Wikipedia is not a place to learn, but it's a
                 damn good place to start, esepecially for computer stuff.
                 The real answer is "find a highly recommended textbook,
                 buy it and read it." but you were clear about wanting
                 an online resource.
        \_ Go back to school and take a course or two. If you are going
           to put in the work you may as well get credit for it. Also,
           the structure and ability to ask for help are plusses.
           \_ What good is a course credit or two to someone who already has
              a long and successful career?  He wants to learn a few specific
              topics.  He should buy a book or find an online tutorial and
              read the parts that matter to him.  He may (or may not) stumble
              into other interesting things that would've been covered in a
              class and without the hassle of class.
              \_ Many Master's programs are only about 8 classes so 2
                 classes and you are already 25% of the way there. I know
                 lots of people with PhDs even who went back for an MS or
                 even more than one MS. Like I said, if you're going to
                 put in the work you may as well get the credit. Put
                 another way: Why *not* take classes? What's the advantage
                 to avoiding class other than cost, which may not be an
                 issue if work pays for it?
                 \_ Because learning a few specifics from a book/article is
                    a hell of a lot less effort than taking a class, doing
                    homework, being there at specific hours several days a
                    week, kissing some instructor's ass for the "A", paying
                    fees (poss. covered by work as you noted), having your
                    learning slowed down by the inevitable time wasting
                    morons in class, etc, etc.  If he wants to learn entirely
                    new branches of knowledge then sure take a class, but that
                    isn't what OP appears to be looking for.  I wouldn't
                    suggest someone take all of Math 1B if they only wanted
                    to learn Taylor's Series which can be learned in a few
                    hours at worst.  Some people are addicted to school, that's
                    fine, gather up all the dgrees on the planet if that's
                    your thing, other people just want to get work done.
           \_ I've learnt a hell of a lot post school without going back.
              Having a degree means you should know how to learn.  (Unless
              your problem is a lack of discipline.)
              \_ I didn't say you couldn't learn that way. I just don't
                 think it's the best way. Who do you ask for help when you
                 get stuck? Without exams how do you know that you really
                 "get it" or just think you do? Who helps you separate the
                 wheat from the chaff? I think every engineer or
                 programmer does a lot of self-learning. That's almost a
                 requirement. However, "knowing how to learn" isn't really
                 the issue here.

4/8     What defines upper class, middle class, and lower class? Income?
        Post tax income? Post tax deduction income? How about asset and
        liabilities? I mean, don't most homeowners with mortgages have
        LIABILITIES since they OWE money? If we count mortgage and
        credit card debts, wouldn't most Americans be lower class?
        \- YMWTR: PFUSSEL: Class. I personally think that is a crappy
           book, but YMMV. You cannot use income alone because of the
           "well known" "graduate student problem" ... i.e. the wealthy
           harvard/bennington classic major with no income but a lot
           of wealth. I think the Robert Nozick "life chances" approach
           is not a bad one, but ultimately these kinds of definitions
           depend on what kinds of questions you are trying to answer.
        \_ Hey dumbass, it's 4/9 not 4/8

           dollars, but my property is worth more than I owe by a long shot.

              it and make profit. Until then, you're just a theoretical
              paper millionaire.
              \_ Spoken by someone who doesn't have the first clue about
                 investing. Do you think that the wealthy keep their

                 \_ Have you been keeping track of this housing bubble
                    \_ All investing involves risk, that is why you get
                       a premium for it.
                       \_ Homes are not investments.  They are shelters.
                          \_ "My property" is a multi-unit investment. How much

        \_ Upper Class - People whose daddy paid for them to go to an Ivy
                         league school and get a non-technical education
                         and/or people whose daddy was a "Lord," a "Sir,"
                         a "Duke," blue-blood from Massachusetts, &c.
           Middle Class - People who went to public school and got a
                          technical education and in all likelihood ended
                          up working for someone whose daddy paid for them
                          to go an Ivy league school for a non-technical
           Lower Class - People who went to state school for a non-technical
                         education which qualified them to make overpriced
           Under Class - Everyone else.
           \_ Interesting that you define it by education level.  What about
              someone who worked through a good college?
              \_ Upper Middle Class - Worked his/her way to a technical degree
                                      at a good school or a professional
                                      degree (jd, md, cpa) at a decent (above
                                      3d tier) school
                 Note: This does not include those who worked at daddy's law
                       firm, daddy's IB, daddy's congressional staff
                 \_ Those who funnel a constant supply of fresh interns for
                    daddy's consumption.
           \_ What is "public school" vs. "state school"?  Are you using UK
              terminology here?
              \_ I am using ther terms interchangably. My perspective is that
                 someone who went a public (state run/funded) school for a
                 technical education is most likely middle class, i.e. your
                 average engineer, scientist, &c. If you went to a top public
                 school (e.g. Cal), you are probably upper middle class, as
                 I think that someone who worked their way through a technical
                 degree at a good school (public or private, i.e. Cal, MIT,
                 CMU, &c.) or worked their way through a professional degree
                 at any decent school is likely upper middle class. Basically,
                 if you are upper class, why would you have to work your way
                 through school? And if you worked your way through school, it
                 probably means you need to keep working to keep your life,
                 family, &c. going. If you are upper class, you don't need to
                 work to keep things going.  Well, unless you are one of the
                 impoverished aristocracy. But, I've already covered that.
                 \_ What if you work your way through school, get a job at
                    Google pre-ipo and are suddenly worth $40M and retire
                    at 30? Are you upper class or middle class or what?
                    \_ I think such people fall into the "lucky bastard"
                       class. But if they let the money go to their head,
                       I think they end up in the "pompous ass" class,
                       which has some essential similarities with the upper
        \_ Family background, education, wealth, manners.
           \- i think the appropriateness of this "quintile" model depends
              on what question you are trying to answer or what phenomena
              you are interested in. for example i suspect there isnt
              a lot of competition or rank consciousness between the students
              ranked 80-90th in a graduating class and the students ranked
              60-70th out of 300 ... compared to the people in #1-5. the
              wealth axis is the interesting of there w.r.t. to sloda people.
              \_ It should actually be the manners axis that sodans should
                 be concerning themselves with.
                 be concerning themselves with. But some people wouldn't have
                 any class, even if they made millions.
              \_ Most amusing is that in order of prestige, they have doctor,
                 lawyer, DBA, system administrator as 1, 2, 3 and 4 (out of
                 hundreds). I never knew that system administration was so
                 well respected.
                 \_ Oh, it is very well respected to people who are not
                    in tech. They think that sys adms have "root" and thus
                    are the almighty ones who rule the tech world.
                     \_ Are we not?  I'm surprised that DBA was ranked
                        higher.  DBA is even more blue collar than Sys Admin
                        in my experience.
                        \_ Wall Street DBAs are very very well respected.
                           \_ No, not really. They are well compensated, but

6/28    People say good things about servlets-- shared connection pool,
        shared resources, not having to fork new proc, not having to
        interpret, etc. However, the chart below says otherwise. Is
        this consistent with what you guys have experienced? It appears
        that Servlet is the big loser here:
        \_ Well, "servlets" is a pretty big category.  Tomcat is pretty sucky
           yes (it's 100% java, what do you expect?) but there are other
           servlet engines out there.  Also from looking that their
           methedology, it doesn't look like they increased the number of
           concurrent worker threads for tomcat.  My memory is tomcat is
           set to use some piddling number of threads in the default
           configuration, which would totally make those results make sense.
           \_ Yeah, tomcat is the reference implementation and is not
              taken seriously by businesses that have clue.

2/9     Looking for a Javascript slider bar example. The first example

        global variables, method conventions suck, etc. Thanks!
        \_ I don't have an answer for you, but what do you think of this
           \_ From the article:
              "Although it's gotten significantly better with ECMAScript
               standardization, I would still rather program with Java than
               JavaScript, the main reason being inconsistency. Maybe in
               eight years the current version of ECMAScript will be standard
               across almost all browsers. But the current version of
               JavaScript, despite the random implementations, is already
               available, and there are zero installation issues. I think
               that's a fairly good proof that the reason Java hasn't taken
               over as the RIA language of choice is the installation
              This doesn't lend much credence to the author's argumentation or
              critical reading skills.  That said, I think it's an
              interesting read, particularly some of the resources it links
              to. -dans
              \_ Whoa, didn't realize the author was Bruce Eckel.  I'll chalk
                 the bad quote up to a goof as opposed to overarching
                 incompetence. -dans
                 \_ Christ dans, you're an asshole.
                    \_ Yeah, but I stand behind my words. :) Though, it does
                       beg the question, why does pointing out a flaw in
                       someone's argument make me an asshole?  Or is it
                       because I believe flawed arguments are a sign of
                       incompetence?  Or is it because I excuse Bruce Eckel
                       the occasional goof in light of a long history of
                       insightful commentary? -dans
              \_ I think he's saying that Java is a better language but
                 Javascript is easy to install.  Since Javascript is where so
                 much RIA action is, that suggests the installation difficulty
                 as being very important.
                 \_ Yes, I get what he's saying.  He's just saying it badly.
                    Also, having read the entire article, I think it would be
                    more accurate to say he's saying that the available
                    implementation(s) of the Java language are better than the
                    available implementations of Javascript.  Having written a
                    fair amount of both, I feel that Javascript is a *far*
                    better language. -dans

                       \_ The short version: JavaScript is Lisp with Algol
                          (for the non-language nerds reading this, C) syntax.
                          A bit of elaboration on the short version: Lisp
                          (and functional languages in general) have a lot of
                          powerful tools (e.g. lambda/anonymous functions,
                          closures) built in that many procedural languages
                          lack out of the box.
                          On top of that, Javascript is a *really small*
                          language.  There's something counterintuitive there,
                          which is that, in my opinion, JavaScript, which is a
                          much smaller language than Java (I mean the core
                          language, not the libraries) somehow has line for
                          line/operator for operator more expressive power.
                          Note that I'm not bagging on Java because it's
                          procedural; I love C.  In general, I've come to the
                          opinion that a small (but complete) language is a
                          sign of good language design.

           that is not contractually guaranteed.  You could get two different

           happen.  If you need to force some finalization code to be called

           If you do so, remember that you may still have other references to

                       the blind. Also, CS/engineering/science is so
                       demanding that there's little time to socialize
                       outside of class. The bus admin folks tend to party
                       more because they have the time to do so.
                       \_ I'm doubtful that, if one is a poorly socialized
                          geek when one enters university, one is likely to
                          learn better social skills from class discussions in
                          any discipline.  You probably had to take at least
                          one English class with a discussion component.  Do
                          you feel that your social skills improved as a
                          result?  I agree that CS/engineering/science are
                          demanding, but I had a rich social life while
                          pursuing a CS major.  I think it's more a question
                          of priorities.  Having a life was important to me so
                          I made it a priority.  I guess I'm just doubtful of
                          your assertion that BizAd classes teach social
                          skills, or that BizAd majors are somehow more
                          socially gifted than CS majors, and, even if that is
                          the case, that this would rub off on a typical geek.
                          Also, I should note that almost all the people I
                          know who are throwing parties (i.e. raves, club
                          nights, etc.) post-college are geeks. -dans
                          \_ Geeks throw parties, too, of course. That's
                             beside the point. Who is learning more about
                             social interactions? An EE at home with his
                             breadboard at night and a class full of nerdy
                             guys during the day or a Spanish or Theater
                             major? My roommate majored in Spanish and
                             French and knew a lot of people from the
                             in-class interaction. It's not quite the same
                             as being in a Chem Lab with someone. As to
                             whether it would 'rub off' on a geek, I think
                             it does to some extent. Imagine being shy and
                             being surrounded by introverts. Now imagine being
                             surrounded by friendly, outgoing people. Which
                             one is going to do more to help you get out of
                             your shell?
                             \_ True to an extent, but I dispute that:
                                a) The majority of engineers are introverts
                                b) Even if I grant that the majority of BizAd
                                   majors are extroverts, I doubt they are
                                   necessarily friendly-- the business
                                   disciplines tend to be highly cutthroat.
                                c) I know many introverts who completely close
                                   off in a room full of extroverts.

2/21    What is the best way to get the current method name in Java?  So far
        I have seen 3 approaches:
        1. Create new Exception, grab the first frame off its stack trace.
           Inelegant, requires creating a stack trace (expensive).
           \_ Yeah it sucks.  Yeah it does much more work than you need.
              Yeah it is really fragile and may break when you switch java
              implementations because some moron changed how stack traces
              are printed.  Still, the few times I've seen libraries
              that generate method names this is how they did it.
        2. Generate new stack trace, grab the first frame.  Same problems as
           above but slightly better.
        3. For each method, define a static final String containing its name.
           Very fast, but makes the code 'brittle' in terms of refactoring and
           makes classes needlessly cluttered.
        Anyone know a better way?
        \_ A little more information about what you are trying to do would
           be helpful. The obvious answer is you wrote the method, you
           should know what name you gave it, but I assume this is not
           tenable in your context. Have you looked at com.sun.jdi?

                    keeping me away.
                    \_ AspectJ generates vanilla java bytecodes. Any

1/17    Java compiler help please.  I have some code like this:
        import com.foocorp.foolibrary;
        class myClass {
          private static final boolean useFooLib=false;
        And the problem is that if I turn off useFooLib and try to compile
        with out foolibrary.jar the compile fails.  Is there any way I can make
        this work without distributing foolibrary.jar with every build?
        \_ I haven't had to think about this for a while, but maybe you
           can use a custom class loader?  What about reflection?
           \_ Yeah, I went with that, starting with Class.forName() as
              suggested below.  Between reflection and commenting out multiple
              blocks it seemed like the lesser of two evils. Thanks.  -OP
              \_ Interesting I was not aware that javac allows you to delay
                 type checking, to see whether method doStuff() exists or not.
                 Thanks for pointing this out. Motd is great!
                 \_ Um, that's not what I said.  I used Class.forName() to
                    dynamically load the class, then I used reflection to
                    get the methods I want, then invoke those methods on
                    the class object (thet are static methods).
              \_ I think the cleaner way to do this is to create an
                 interface -- FooClassInterface. Include that in your
                 normal code path, but you don't need to provide an
                 implementation. Make FooClass implement that interface
                 then you can do:
                   if (useFooLib)
                        FooClassInterface foo =
                          (FooClassInterface) Class.forName(...).newInstance();
                 I think that's preferable. - guy who made below suggestion.
                 \_ Won't work.  FooClass is a partially-obfuscated JAR
                    licensed from another company.
        \_ Java is not C. If this were C, the statement "if ..." would be seen
           as dead code due to constant propagation. However javac does flow
           analysis before optimizations so requires method/var resolution
           first and you can't possibly compile with safety without foolibrary.
           If you must include such a dead code, manually comment out the dead
           code or just include the foolibrary.class|java with the distro.

1/16    Okay, I have a technical question here. I administer a cluster
        of java webservers running jetty (not resin, sorry). They are behind
        a load balancer. They used to start up fine under "load" i.e. in
        the load balancer configuration. The latest code release
        broke this somehow and now they crash upon startup unless
        I remove them from the load balancer first. The programmers
        promised to fix this, but of course they did not and now
        they claim this is "industry standard." It is burdensome
        to me to have to remove them and then re-insert them every
        time I need to do a restart. Does anyone else run a java
        webserver cluster? Do you have to remove them from your
        load balancer everytime to start them up or restart them?
        I already STFW and could not find anything on the topic. -ausman
        \_ What I would do (I've been in similar situations):
           1) Escalate to CTO so he knows #2 is coming:
           2) "No, I can't bless this release because your P1 bug isn't
               fixed.  You'll have to explain to the CTO why this bug hasn't
               been foxed."  This will trigger a meeting where you can say:
           3) "This is an industry standard?  The code wasn't broken until
               release X.Y.Z on date MMDDYY which you said was going to be
               fixed.  Find me the IEEE, IETF or other industry standards
               body doc that says this is standard."
           If you don't push back hard on this you're only setting yourself
           up for even worse hassle down the road.  I've 'worked' with code
           monkeys like that before.  They're classic bullies.  Hit back hard
           immediately and be rude about it unless you want to be their ops

              code here that I am trying to change. Fortunately, we have
              a new CTO who supports my general philosophy on this.
        \_ Yes, and no. Since you didn't supply more information on how
           you're accomplishing load balancing, I have no idea how to
           fix your "problem".

                 a debug trace out of it?
                 \_ Yeah, 9000. All kinds of errors, untimately leading
                    to a server crash and restart which then crashes and
                    then tries to restart...
                    then tries to restart... I am trying to dig up the
                    exact error for you now. Actually, email me for details,
                    I don't want to post it on the motd.
        \_ That proves it isn't "industry standard".  Escalate and get the
           programmers whipped into shape.
        \_ They promised to fix it?  Do you have that in writing or in a bug
           tracking database?
           \_ No, but they promised in the code release meeting, where I
              have to sign off on code releases. I only agreed to let this
              code go live on the condition that they would fix it later.
              The CTO, who is in charge of both my group and programming,
              was there. So I definitely can push back if I want to, but
              I need evidence to make my case. It is probably true that it
              is less overall time to do the laborous restart than it is
              to fix the bug, at least in the short term.
              \_ Unless it's an architectural problem that will compound as
                 they continue to build on the existing architecture.
        \_ Sounds like an excellent opportunity to set up a script to handle
           updates.  Take node out of load balancing, restart it, test that it
           started cleanly, and then put back into balancing.   Been there,
           done that.

7/15    Is it possible through JNI to write a function which takes a float[]
        array and through the magic of c casts it to an int array and then
        returns the int array to Java, not modifying the actual data?
        If not, is there a good Java way to do the C equivalent of:
        int* i = (int*) f; ?
        Don't ask whether I really need to be doing this because there is a
        good (performance) reason.
        \_ You can modify your implementation of VMFloat, or create a new
           class similar to it, to provide an additional method that works
           on arrays of ints and floats, rather than just on individual 32
           bit values.  This will entail creating a new shared library, etc.
           This is probably the cleanest and most efficient way, but obviously
           will not be portable.  I am assuming you know how to write the
           C necessary to convert the array type while leaving the bit
           representation unchanged. -- ilyas

              \_ I do not know of such a way.  I think when you are starting to
                 care about performance to the extent where you don't want to
                 just call floatToIntBits on each element of the array, you
                 should either forget platform independence, or use a better
                 language.  By the way, the previous poster is wrong, there
                 is no reason Java shouldn't provide this functionality in
                 VMFloat (it provides a function for individual 32 bit values).
                 It just doesn't because it sucks. -- ilyas
              \_ Sure:
         for(int i = 0; i < float_array.length; i++){
                int_array[i] = java.lang.Float.floatToIntBits(float_array[i]);
                If you want to avoid the overhead of a loop, or aren't
                willing to write your own shared library + class wrapper to
                do what this loop does in one swipe, or aren't willing to
                abandon Java, then you lose. -- ilyas

                   O(n) step, and am too lazy to write another JNI wrapper.
                   I guess I do lose.  I also saw ByteBuffer has methods for
                   providing IntBuffer and FloatBuffer views, but I can't find
                   a low overhead way to go FloatBuffer->ByteBuffer or
                   \_ For reference, consider how a well-implemented strongly
                      typed language (ocaml) handles this:
                      let float_array = [| 1.0; 2.0; 3.0 |] in
                      let int_array : Int32.t = Obj.magic float_array in

        successful who read maybe .5 - 1 book a year, e.g. my housemate
        has an MBA from MIT/Sloane and is essentially retired at 48.
        I'm not sure he has read 2 books in the 2yrs I've lived here.
        He does watch various news and informational TV programs so he's
        not clueless about the world. This does not include "HowTo" books.
        \_ I generally don't make time for reading, though several times
           a year I go crazy and read all the books I buy in my off periods.
           In general, though, the books I do try to read when I'm not devoting
           most of my time to it are difficult reads that I go through them
           very slowly.
        \_ I am neither bright nor successful, but I don't really read
           very much.  -- ilyas
        \_ I read a lot when commuting on BART.  Since I had to start driving,
           I've pretty much stopped.
           \- I'm not talking about very much. I mean zero. And I'm not
              talking about do you knock off a Shakespeare now and them ...
              I mean people who dont even read The Da Vinci Code or Michael
              Crichton or other "airplane pilp".
              Crichton or other "airplane pulp".
              \_ When I read, I tend to read classics or books of an
                 informational nature. Most newer fiction is not for me.
                 The last book I read was 'Dune' (again) about a year ago.
                 I am not sure that reading books (especially fiction)
                 indicates much of anything at our age. I used to read a
                 lot more when I was younger and had the time. FWIW, I
                 don't watch TV or go to the movies either. I do read the
                 newspapers and magazines like 'The Economist' religiously.
                 BTW, how come your housemate is a 'housemate' when he has a
                 good degree from a good school? Is he lazy?
                 \- I'm not suggesting anything about "our age" ... this was
                    asked on the soda MOTD and I'd think the soda motd has
                    a marginally higher literacy rate than "our age". Of course
                    people here are more likely to have the web suck up their
                    time. And I am not talking about reading but reading
                    books. A lot of these smart-but-non-readers read the
                    newspaper and other practical books like the Idiot's
                    Guide to DVD burning etc.
                    I dont understand the "why is your housemate a housemate"
                    part of the question.
                    \_ What I mean by 'our age' is that a kid who reads a
                       lot is probably bright (not sure about which is the
                       cause and which is the effect). I do not think this
                       is true once you reach adulthood. If someone reads
                       10 bodice rippers a week does that imply anything about
                       his or her intellect or lack thereof? 'Number of
                       books read' by itself is meaningless at this stage of
                       intellectual development. Someone who reads the NYT
                       and Wall Street Journal every day is quite likely
                       doing more for themselves than the bodice ripper
                       person. As for your housemate, I am wondering why
                       he doesn't have his own place when he has a graduate
                       degree from MIT. That sounds rather odd. I'd worry
                       about that more than about how many books he reads.
                       \- I was not the one equating "reads" with
                          intelligence. If anything I was saying that I
                          found it odd a fair number of pretty intelligent
                          people *dont* read ... or if you go to their homes
                          you will not see 10 books. I agree a lot of people
                          who read pulp somehow think that is supirior to
                          wantching TV, when they are essentially the same
                          thing ... and then there are people who watch a
                          HISTORY CHANNEL show on Rome and think that is
                          50% of the way to reading R. SYME: THE ROMAN
                          REVOLUTION when it is closer to like 3%. Re: house-
                          mate: he owns multiple millions of dollars in
                          real estate. I can only assume he lets me live here
                          because of my wit and charm, since he clearly doesnt
                          need my meagre rent.
        \_ I haven't read a book 'for fun' since I graduated several years ago.
           Reading is on my 'todo' list but never rises to the top.  I have
           other things I'd rather be doing or need to be doing.
           \_ Interesting.  I didn't have time to read at college, but now
              that I work I read voraciously.
        \_ Before to law school I was reading about 1 book every 2 weeks
           or so (mostly non-fiction - science/history/&c.). Now I pretty
           much only read my casebooks or related material which amounts
           to around 300 pages a week (or more).
        \_ I had pretty much stopped reading for pleasure by my junior year as
           an undergrad.  Then I married a librarian.  I read like crazy now
           (and keep having to get more bookshelves).  -emarkp
                \_ Why does being related to a librarian always make people
                   read more? Is it because they bring home books, or that
                   they get good recommendations at work, or that they read
                   a lot themselves and pass the book on, or what? I've known
                   several sons/daughters of librarians, and they're all
                   avid readers.
                   \_ If you didn't love books, you wouldn't become a librarian
                   \_ Speaking as the son of a librarian, I think the
                      factors are mostly envionmental.  My mother read to
                      me a lot as a child.  There are always books around
                      the house.  We went to the library (as a family)
                      weekly.  We got books as presents.  Mom was always
                      reading books. etc. -jrleek
                   \_ In my case, she had a lot of great books that I'd never
                      read.  Now we recommend books to each other. -emarkp
        \_ No, we're too busy reading motd. =) But seriously, I read newspaper
           and website for things that used to be available on printed media.
        \_ Sometimes books have a hard time competing for my attention with
           all the other stuff there is to do... I don't read as much as I
           would have liked. I occasionally get into a mode of reading a number
           of books. If I get "stalled" in a book it tends to kill my reading
           habit for a while and I'll go play videogames instead or whatever.
           I stalled out of a few books lately when I tried reading more
           classic literature... I made it halfway through Karamazov before
           giving up. Master and Margarita didn't capture me after a partial
           attempt. For Whom the Bell Tolls I picked up after really enjoying
           The Sun Also Rises, but I kind of trailed off halfway through that
           also. I'm 3/4 through The Iliad translated by Robert Fagles, which
           doesn't seem as poetic as whatever unknown translation I read
           a little bit of in college. And the storyline gets a little bogged
           down with the endless battling and slaughter.
           I hope to just get those two done and then stick with lighter
           stuff for a while. I had fun reading short stories since they
           can be done in one sitting. Hard Boiled detective stories and Fritz
           Leiber's Lankhmar tales were the latest I read.
           Lately I've just been listening to audiobooks while I fall asleep or
           over breakfast... at least I get through stuff that way.
           \- imho, the iliad is not something you can read without "guidance".
              best is to read it in a class with a good teacher, but even
              reading a good introduction may be enough. i say this for two
              reasons: 1. it is a very "alien" work so you are likely to
              arrive at some incorrect interpreations unless you are waved
              off [like say with the metrical rather than descrptive function
              of the ephithets] 2. it is an amazingly complicated work and
              there are some structures/methods that you'll need some
              examples pointed out ... after you know what to look for,
              there are some structures/methods that you'll need some to be
              pointed out ... after you know what to look for,
              then you can look for these on your own [like some details of
              "ring composition", or the way HELEN is described in the
              famous "Teikoskopia"].
              \_ You're probably right... this book does have a relatively
                 long introductory/preface section and appendices etc. and
                 I did have part of the Iliad as class material at Cal (but
                 I really bailed on that class and I think the focus was
                 not on the literature but the mythological ideas). It does
                 describe at least some of what you're talking about. I have
                 describe at least some of what you're talking about. I
                 have to be in the proper mood for it... I also have the
                 Odyssey from the same guy. I did not compare translations
                 beforehand so I kind of wonder if I'm missing out on something
                 But it's hard to say what the "real" approach should be. The
                 guy of course argues his way best captures the feel. Oh well.
                 \_ psb is right.  It's not just a matter of being in the
                    'mood,' you need a lot of background on their society, the
                    way they thought, their entire moral and metaphysical
                    framework was completely different from ours.
                    \_ I meant in the mood to enjoy reading it. This motd
                       stuff got me into it again for now...
                    \- "moral and metaphysical framework" nicely captures
                       what is at issue in my first point about the "alieness"
                       of the "world of odysseus". but the structural elements
                       unique to oral composition [the parry-lord-parry stuff]
                       in general or homeric epic in particular [like the
                       telescoping of the 10 years of the conflict into the
                       short period covered by the iliad] is a different set
                       of issues. in fact there is one more, which is the
                       philological ... like greek language has "aspect"...
                       but that stuff is beyond me. and i think that has
                       \_ I wish schoen@@csua would login and post.  He would
                          know more about this I bet. -- ilyas
                          \- are you a russian? doesnt the russian language
                             have notoriously difficult aspect in addition to
                             tense? then this may be easier for you to follow.
                             the closest i've read to a philology heavy book
                             is G. Nagy: The Best of the Achaeans. very good.
                             \_ I think aspect distinctions exist in English,
                                too.  English just lacks a general mechanism.
                                I don't know how sophisticated greek aspect is
                                compared to russian aspect. -- ilyas
              I didn't know what aspect was, so I found this elucidating: _/
                        \-yes that was sort of my point. some of this stuff
                          is not like "oh yes the clever boy in the english
                          class got more out of reading Ozymandias than i
                          did" ... there is no hope you will get some of this
                          stuff because it just doesnt exist in your brain,
                          it's not a matter of insight and figuruing it out.
                       diminishing returns for a "normal person". i note that
                       even 5th cent BC athens is much less "alien" and
                       easier to understand. with some exceptions like the
                       \-BTW, I like the Lattimore trans the most probably
                         but I think Fitzgerald and Fagles are reasonable.

                         I think Fitzgerald and Fagles are reasonable.
                         Perhaps the 100s of pages of Fagles cant compare
                         to the "highlights" you remember from college.
                         if you want to really go for the poetic one, look
                         at the pope translation. not user-friendly, tho.
                         FACTOID: T.E. Lawrence (of Arabia) did a prose
                         trans. of the Iliad and Odyssey.
                        \_ That may have been it; I will look into it next time
                           I'm in a book place. There are a couple of passages
                           I will know it by. I found Pope online and this too:
                           That last version has some ridiculous (IMO)
                           Shakespeare dialogue like "wherefore art thou" that
                           seems out of place. The Fagles stuff is certainly
                           very readable; I guess it seems too casual at times.

6/10    I'm trying to write my own Java properties file reader so that I
        can get something similar to C's #include macro, but I'm having
        problems getting the properties back from System.getProperty().
        For example, I'll call System.getProperty("foo") and get null
        back, but printing out all properties (via
        System.getProperties().list(System.out) ) clearly shows "foo=bar"
        in the output.  I've tried loading the file using different
        charset names (ascii, utf8, several other usual suspects) but that
        hasn't helped.  Has anyone seen something like this before?  TIA.

5/2     Could someone offer a tip on how to write thread-safe (Java) code?
        I have a class which performs some work, and I want to allow only one
        thread to be in the do_work function, but allow many threads to enqueue
        work.  How would I do this?
        class Worker {
          private void dowork(Work w) {...}
          public void enqueuework(Work w) { ...}
          private Queue workqueue; // A FIFO queue of Work objects.
        \_ Look into the synchronized keyword. If nowhere else, the Java
           language spec has an acceptable description.
        \_ The above answer isn't quite enough. Here's how you do it
           in general, gross terms, you'll have to do some tweaking and
           look up the Java-specifics yourself:
        \_ The above answer isn't quite enough. This isn't 100% correct,
           but it should point you in the right direction:
                -- The do work thread should start running in a loop
                   which locks a synch variable, process anything
                   in the queue, and then waits on condition variable
                -- The enqueue method should lock the synch variable
                   put stuff into the queue, and signal the condition
           See also: (
           - ciyer
           \_ Shouldn't it be sufficient to use the synchronized keyword on
              the doWork method?  The enqueuework method doesn't need to
              be synchronized, right?
              \_ It does if you're writing unsynchronized data structures
                 in the enqueueing operation.

4/27    Dear Java gurus, say I have the following code, where Visitor()
        has a method called "visit(Node n)...". I see the following code.
        Does it mean I'm temporarily over-writing the visit method?
         root.accept(new Visitor() {
            public void visit(Node n) {
               //Do stuff with n
         \_ for a lot more on the above code, see Erich Gamma's book
             "Design Patterns" (introduction and visitor pattern)
        \_ It's an anonymous class and yup you've got it.  Even more
           useful is the fact that as long as you have final variables
           in the code that calls visit, you can use those variables
           in the redefinition of visit.
           final Long x;

3/19    I'm writing a simple GUI interface for an existing text-only Java

        to entice new clients. Should I write the GUI in Java AWT/Swing which
        I'm more familiar with (advantage:all in Java solution, disadvantage:IE
        users needs to install VM) or should I write it in Flash
        (advantage:more lightweight than VM, more readily available on
        browsers, disadvantage:I'll need to learn Flash, which shouldn't be
        harder than AWT/Swing I hope). What do you guys think?

       I tend to agree with him, as I've seen relatively little gain
       from such languages as C++ and Java in terms of creating better
        \_ I thought it was pretty sophomoric, really.  OOP is a tool that is
           often used poorly.  If used well, his comments are all wrong.  But
           that's the same of any technique.
           \_ Actually, I think you missed the point. If a tool is often used
              poorly, then why do we have the tool in teh first place? i.e.
              if a hammer is poorly designed so that people use it the wrong
              way, get rid of the hammer and find a better one. OO is often
              used poorly because it's been designed poorly. I.e. people
              think it's "cool" to use C++ or Java to program in because
              it's got wonky crap features in it like templates and
              object overloading and container classes. There are so many
              tacked on features in Java nad C++ now that you need tomes
              and tomes of printed material to just document the stuff.
              So programming becomes basically a websearch project, which
              it shouldn't really be. We don't need six layers of abstraction
              to get to pushing bits over TCP/IP. We also don't need
              six layers of abstraction to calculate the cost of a pair of
              shoes being bought online.
              \_ Ok, I'm not pp, and have absolutely *no* opinion on the
                 relative merits of C or C++ or Java or whatever, but I have
                 to say something about your tool comment.  In my observation,
                 the *vast* majority of people do not know how to use a toilet
                 plunger correctly.  Does that mean we don't need toilet
                 plungers?  Can you suggest a superior tool for the job?
                 One other solution is to have a basket full of pointy sticks
                 next to the toilet which users can use to break up their turds
                 with a stabbing motion.  This is certainly a more
                 self-expanatory tool, but it is also inferior.  First of all,
                 it doesn't help you if the offending turd has already passed
                 the U-bend, and second of all, it leaves you with a shit
                 covered stick that you have to dispose of.
              \_ Hehe.  Wonky features like container classes.  I think the
                 fault of C++ is not the amount of features it has (most
                 of them are there for a reason) but the way they fail to
                 come together as a coherent, organic whole.  Stroustrup is
                 a smart guy, but an artist he is not.  It's telling that
                 you think Java is featureful, Java is one of the most
                 featureless languages I know of. -- ilyas
                 \_ Well Strou built it on C so it can't really help being
                    ugly. It feels like it wants to be another language but
                    it lives in C land for practicality. Kind of how Windows
                    lived in MS-DOS for so long.
              \_ In the US of A, we have the FREEDOM to use C++ poorly
              \_ No, I didn't miss the point.  The point is crappy OOP gives
                 crappy results.  OOP used well has huge benefits.  That's the
                 difference between a beginner and an experienced SE.

        uint source, char data[1500], uint crc};".  Then in order to
        put stuff into data, I'd do casting as follows:
            tcp_data = (tcp_struct *)&frame_var->data

        \_ No, it's more than that. You're dealing with invoking and calling
           remote objects, not simply serializing them over TCP/IP. It isn't
           as simple as what you propose.
           \_ so let me ask differently. Can RMI be implemented in Java using
              non-JNI stuff, using simple Serialization, book keeping data
              structures, etc? What is it so magical about RMI?
              \_ Technically yes, RMI can definitely be implemented not using
                 JNI. After all, RMI is a published spec, and you could write
                 it in pure Java. The reason JNI is used is because for low
                 level serialization through TCP/IP native method calls to
                 C functions is much faster. After all, OO request brokering
                 is rather CPU intensive (If you didn't know that I would
                 suggest you take an advanced course in OO and do some

        I/O API in JDK 1.5.  Looks great.  Except I can only save an
        Image would I go about coverting my JTextField to an
        image?  Thx - clueless

9/29    Does bittorrent work with Linux? I've been trying to download it but
        it's in a damn RPM and I don't have root access.
        \_ Umm, most bittorrent clients aren't RPM's.. in fact, the first
           one was written entirely in python
        \_ Get the Azureus client off sourceforge.  Nicest one I've seen and
           runs in Java.
                \_ alright I downloaded the jar, how do I friggin use it
                   when they don't have HOwTOs and documentations?
                   \_ "How do I run a Java program?" STFW.
                \_ java -jar Azureus2.1.0.4.jar
        Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/swt/widgets/Display
        So what is this eclipse shit? Man the documentation sucks.
        \_ It sounds like you might have an old version of the JRE.
        \_ You want to do torrent downloads on a machine and you don't have
           root?  Have you checked your user agreement?
        \_ I'm on DSL so I tried using this to limit the transfer
           rate as to not piss off my apartmentmates:
           However, it's still pretty lame as DSL is slow, so I've
           been thinking that I should use Linux at work with a much
           bigger bandwidth. However, I don't have root to install
           the RPMs.                                    -op
           \_ Azureus also does upstream bandwidth limiting, and running a P2P
              app at work is a good way to get your ass fired.

9/23    Do you find a lack of respect for s/w developers and/or sysadmins
        in your workplace? I am in management (former sysadmin) and
        hearing management's opinions firsthand is now shocking and
        depressing. Time to switch careers or are there places that treat
        IT with respect? BTW, my team has members from Caltech, Harvey
        Mudd, USC, Berkeley... so it's not like we're a bunch of idiots
        at a help desk.
        \_ My experience is that people hate IT because they are highly
           dependant on them, they usually get paid manager scale salary
           or higher as staff and most sw dev and/or SA are incompetent
           assholes.  There really truly are enough real fucking losers out
           there that it makes all of us look like shit forever.  When you
           meet these people kindly ask them to find a new field and when
           they don't, it is ok to knee cap them with a bat.
           \_ In my experience, incompetent assholes are much more prevalent
              among management than among software people or sysadmins.
              The higher the position, the more likely the guy is an
              incompetent asshole. -- ilyas
              \_ ilyas, have you ever read Alan Cooper's book "The Inmates
                 Are Running The Asylum?"  I highly recommend it to anyone
                 that thinks software people _aren't_ the problem.
                 \_ I haven't read it.  But isn't that book about problems with
                    software development?  I thought this thread was more
                    about problems in computer industry corporations?  Actually,
                    I think the problem is wider than the computer industry.
                    In my more marxist days, I can't help but think there is
                    a middle management parasite class. -- ilyas
                    \_ You mean you really are a dictionary-definition "neocon"?
                        -- ulysses
                        \_ I don't know what that word means. -- ilyas
                           \_ Do you have a tough time with reading
                              comprehension? Or do you just disagree with
                              the Christian Science Monitor defintion of it?
                              \_ If Cheney and I are both neocons, then that
                                 label is meaningless.  I disagree (or at
                                 least disagreed in 2000) with Cheney on
                                 almost everything. -- ilyas
           \_ I just heard a line from a guy I work with that you might
              appreciate.  "Sure, I'm a minority.  I'm in the minority of
              people who know what the fuck they're doing."
           \_ Well, yeah THAT's true.  You should see some of the crap IT
              people there are out there.  Clueless and unwilling to
              learn.  The worst combo in IT.
        \_ If you fail to understand the hatred of sysadmins/IT types
           by almost all workers of all types(including even blue collar
           workers now) you are probably part of the problem.  As my old
           boss from when I worked in the fishing industry put it "it's
           getting to where you can't take a shit without dealing with one
           of these pointy headed computer fuckers."  Computers are
           loathesome for most people to use, and their major human contact
           with this issue is through IT people.
        \_ my manager said there's no respect because engineering is just
           a disposable resource. I left that company 5 years ago.
           \_ Is that company floundering?  emarkp's company had an
              additude like that and it died fairly quickly.
           \_ hint: *everyone* is a disposable resource.  if you think you're
              not disposable doing whatever it is that you do then you're
              either a truly unique contributor or you're truly naive.
              *everyone* can be replaced at most companies.
        \_ Here at the lab, we get lots of respect.  Work at LLNL! -jrleek
           \_ That's what they have when you are not in listening range.
              \_ Exactly. I thought the same thing until I got promoted.
                 CS types are supposedly trained monkeys that make too
                 much money "but it's what the market will bear".
                 \_ Ummm.. have you worked at the lab, or are you talking
                    about a different place?  My management is almost
                    entriely CS guys, up until you get the the very top,
                    where it becomes Physics PhDs.  Admittedly, the
                    Physics guys don't think much of CS, but they don't
                    think much of ANYONE who isn't a Physics PhD. -jrleek
                    \_ Until they need someone to fix their Blackberry.  :-)
                       \_ Ah, but the Physics guy could fix it in theory!
                          All this implementation stuff is just
                    \_ You are confirming what I said. The CS guys think
                       highly of CS, but not anyone else (physics in this
                       case). I have worked several places in academia as
                       well as industry and for the government.
