11/7    If I don't need to print for a few months, do I need to keep adding
        new ink to inkjet printers to prevent them from drying and clogging
        heads? Or will it just magically work once I add in new ink
        in a few months?
        \_ The nozzles will clog. Print a test sheet every couple weeks.
           Or remove the cartridges and put cellophane tape over the nozzles,
           like they were out of the box.

6/9     I have a pair of Levi's jeans newly purchased (gift) and they are
        so damn thin I am afraid they might rip just going into the drier.
        WTF has happened to Jeans in the last few decades and which brand
        has the highest thickness to cost ratio?
        \_ I've been wearing Kirkland jeans from Costco for a few years.
           Quality-wise, including thickness to cost ratio, has been very
           good.  Style-wise, I can't tell.

           but you'll have to spend $$ on em. Totally worth it though
           as they look great. Get the made in Italy ones. I've worn some
           for about 2-3 years straight so amortized cost is low.
           \_ If you majored in computer science at Berkeley, and have to
              worry about the amortized cost of your pants, then somewhere
              along the line something has gone horribly, horribly wrong.

8/28    Hi, anybody printed a photo image to a big plotter?  Something like
        36"x36"?  I'm wondering how many megapixels the image need to
        have in order for the print to "look good".  There is a rule of
        thumb?  Like 6 megapixel is good for X size print.  10 megapixel
        is good for Y size print.  Thanks.
        \_ You don't need that many more megapixels for much bigger prints,
           because people tend to view bigger prints from farther away.
           \_ exactly. Pixel peepers are stupid. Anything beyond 20MP,
              is mostly a waste anyways.
        \_ Try thinking of it in terms of dpi on the final print.  Is 150dpi
           good enough?  If so, then you need a 29 megapixel image for 36"x36"
           (36 * 150)^2 = 29,160,000.  The resolution of the printer can also
           limit the quality of the printed image, so make sure the plotter
           can handle your target resolution.  If you're doing this with a
           plotter, presumably you're not trying to produce a photorealistic
           image anyway.

4/5     Tuesday at 10:00PM I will be taking down Soda temporarily to migrate
        disk arrays.  This is an expected part of our move to the new server.
        The downtime should be minimal - I'll be remounting /home read-only
        for an hour or so while I run a final mirror over to the new array
        and then will reboot Soda onto the new array. The final migration
        will come at a slightly later time - this is in preparation for
        moving mail handling.

2/20    Does anyone else think that the new web site sucks?
        Did they _really_ have to redesign the old one, which seemed just fine?
        \_ Be boring like me and use this instead:
  - danh
        \_ I hate this facet of the WWW. People redesign just to look like
           they are doing something and be 'fresh'.
           \_ you think that's limited to the WWW?
              \_ No, but it's more annoying than when, say, the grocery
                 store decides to move the aisles around.
                 \_ The problem is that in the grocery store, the person who
                    is moving the aisles around is a grocer who knows his
                    customers.  On the Web, redesigns are often controlled
                    by people who have no clue what web customers need.
                    Particularly when the web site has a print publication
                    side; print design and web design are two completely
                    different things.  It's like having the grocery aisles
                    laid out by someone whose only experience is in
                    warehousing.  -tom
                    \- often when groceries move stuff around they are
                       doing it to sell more stuff, not for customer
                       convenience. lots of research on the path people
                       take thro stores, effect of placement, getting
                       paid for placement etc.
                    \_ On the other hand, sometimes there is value when a web
                       site bears some resemblence to the print publication
                       side.  Old-fashioned print subscribers will feel more
                       comfortable using the web site.
                       \_ Having the web site bear resemblance to the print
                          edition, and having the web site be usable, are
                          not mutually exclusive goals.  But you need to
                          have a real web designer in charge of the project
                          if you want to reconcile them.  -tom
                          \_ Good luck finding a 'real web designer'.

        \_ If you got less than $10 in interest, you don't get a 1099-INT.
           But since PayPal is a money market fund, it's probably a
           1099-DIV. I'm not sure what the rules are on that.

10/3    My manager and the project manager refuses to have a project plan
        (i.e., schedule).  Instead, they opted to track progress via bugzilla.
        Now my manager wants to know when we can release the product.  I
        told him that we really need a schedule to know that.  He then placed
        the blame on me for not having a schedule.  How would you respond to
        this? -abused employee
            \_ Let me counter with something more useful:
        \_ It sounds like you are the technical lead.  The PM is the PM, and
           your manager is just a middle manager.  As the technical lead, you
           should obtain whatever data you can from above on what the
           schedule requirements are (this can even be just a "complete by"
           date), and create an implementation plan according to any dates.
        \_ Just do your own project management. I have often had to do this
           at various points in my career when my bosses were idiots. This
           also helps make you ready for the jump to the next level, if
           are so interested. -ausman
        \_ This is a pretty standard problem.  Check out the author
           Steve McConnell, and browse through his books Code Complete,
           Software Estimation and Rapid Development.  Trust me, you are

        \_ You made a mistake on day 1 when you knew you needed a schedule
           and didn't make one.  Next time just make a schedule.  Print it
           and email it to your manager.  At that point it becomes his
           problem if he doesn't like it or it doesn't fit business needs.
           For your current situation, you can either flip him off and get
           another job, or you can take the mature approach, tell him it isn't
           about finger pointing but team success, blah blah, and sit his
           dumb ass down to write a real schedule from the point you're at now.
           \_ He was adamant about not having a schedule.  He made it clear
              that he did not believe in it.  He has tried it and it has
              failed every time.  I don't mind working on a schedule now,
              but knowing him, I know he will then turn around and say
              that's something I should have done at the beginning.  So
              instead of being praised for taking the initiative, I will
              get blamed for starting it late.
              \_ Yeah, a lot of incompetent and/or inexperienced software
                 managers behave like this.  I would suggest browsing through
                 those books, or similar ones, that I mentioned.  If your
                 manager is unwilling to make changes and continues to blame
                 you even after you discuss professional engineering standards
                 with him, then you'll probably have to transfer, quit, or
                 bring it up with his bosses.  Feel free to email me if you
                 want to talk about this further.  --peterl
              \_ In this case, if he didn't want a schedule, you should have
                 showed him an implementation plan, but one without dates.
              \_ Wow, that sucks.  What I have learned (the hard way) to do
                 with shitty managers who refuse to follow common good
                 practice or make bad calls is to send them an email spelling
                 out what they told me to do and ask them to confirm.
                 "So, Bob, just wanted to make sure we're on the same page and
                  you don't want a formal schedule for this project."  The
                 smart ones get the message.  The dumb ones will fail and
                 blame you no matter what.  If your manager really is that
                 dumb then sometimes quitting (or finding a new job in the
                 same company if the place is big enough) is the only answer.
                 It still sounds like your situation might be salvagable but
                 I'd have my resume up to date just in case.  BTW, according

8/25    Why are iterators "superior" or more recently popular over the
        traditional method of using  for loops and indexing?
        \_ I guess it's because you can change an array to some other data
           structure (linked-list, tree, ...) without changing the loop code.
           \_ This is a limitation of your language, not the concept of looping
        \_ They handle multithreaded use cases better.
           They hide implementation details.
           You can pass iterators around between functions and they do
           what you want witout much hassle.
        \_ Traditionally doing pointer comparisons is faster than
           dereferencing by index. (Good compilers probably will
           transform the latter for you for simple data structures like
           arrays, though.) Also, they're simply an abstraction that
           better describe what you're trying to accomplish
           (reverse_iterator) or what your needs are (const_iterator).

            src = src << 8;
            src += buffer[1];

           1. Do you really mean to use 1-based array indices?
           2. You're always storing the most-significant-byte in the
              position of the least-significant-byte. (Note that this is
              irrelevant to whether your host is big- or little-endian.)
              Simply writing src = buffer[0] << 8 | buffer[1] should be
              \_ I thought network order was LSB first?  So it should be:
                 src = buffer[1] << 8 | buffer[0]
                 \_ You thought wrong.  Do some homework.
           \_ If you are overlaying a buffer onto the short, that is
              inherently endian-dependent. Use htons, duh.
              \_ He's not overlaying a buffer onto a short.  He's reading it
                 into a buffer first.  When he reads it out of the buffer
                 with shift and bitwise operators, the endianness of the host
                 is irrelevant. (And I'm not suggesting not to use htos, I'm

              the bank record has a mistake, the bank will most likely go by

              does a printout from a web page as good a proof as the fancy
              paper statement from the bank?
              \_ I think you'll find neither of them can prove a balance.
                 the record of transactions is useful so you can ask for
                 details on any transactions that occured which are not

                              Anyway, Cal's fine. I doubt you can get a
                              much better education somewhere else. In
                              terms of price/education ratio it's the
                              best deal on the market.
                                \_ No, I agree with you about the humor and
                                   all. It's only that the anti-Cal sentiments
                                   on this motd are pretty strong and frequent
                                   so I just wanted to comment. Sure I don't
                                   think Cal was perfect, but I still do believe
                                   it is an outstanding university.
                              \_ How do you measure the quality of education
                                 a school provides?  As someone in the business
                                 of hiring the product of schools, I tend to
                                 measure the quality of a school by the quality
                                 of the graduates (which is of course unfair,
                                 since I do not take into account the quality
                                 of the incoming students, but just the
                                 graduates).  However, just measuring by the
                                 the quality of the graduates, Cal is far from
                                 the head of the pack.
                                 \_ You have a self-selecting sample. You
                                    remind me of the recruiter at BofA who
                                    said that I must be bad at math because I
                                    had average grades in math. Nevermind
                                    that the people with a 3.8 in math are
                                    trying to get tenure at Princeton instead
                                    of applying to work at BofA. Cal grads
                                    compete very well overall.
                                    \_ Well, I don't think I self-select in
                                       the sense you mean.  It's somewhat
                                       unlikely that I would see nth quartile
                                       students from other schools and (n-1)th
                                       quartile students from Berkeley.  Cal
                                       new grads just aren't that competitive
                                       compared to new grads from other "good"
                                       schools (mit, the farm, caltech, or
                                       even utaustin (just 1 interview trip
                                       there, but I was impressed)).  If it's
                                       a sop to your school loyalty, I found
                                       CMU students were even worse for what
                                       I was hiring for (EE, not CS, with some
                                       knowledge of circuits and transmission
                                       \_ *YOU* don't self-select. The students
                                          do. Maybe your project did not
                                          attract the best, because it was not
                                          interesting. Perhaps Cal students
                                          are not strong at that one particular
                                          field and you are over-generalizing.
                                          I *do* know that Cal turns out an
                                          awful lot of graduate students who
                                          do top notch work, as well as the
                                          standard doctors/lawyers/businessmen.
                                          At my work, I don't come across a lot
                                          of good Cal grads either, but that's
                                          because I am in aerospace and Cal
                                          has no department. Schools like
                                          Purdue, UT, and MIT dominate there.
                                          What it says about the average Cal
                                          student is absolutely nothing.
                                          \_ So you're claiming that some
                                             difference in Cal students cause
                                             them to be somehow uniquely less
                                             interested in the companies I'm
                                             hiring for.  I find this claim
                                             incredible.  Perhaps you would
                                             explain what is so different with
                                             Cal grads (vs. MIT, Caltech,
                                             'fraud, UTAustin etc.)?  I've
                                             already specified what I look for
                                             in new grads (EE, some circuits
                                             and transmission line).  Could
                                             any EE program that doesn't cover
                                             some circuits and transmission
                                             line be considered a "good"
                                             \_ Completely possible, for
                                                example, if the jobs you
                                                are hiring for are in
                                                another state from CA. However,
                                                what I am saying is that you
                                                are probably not evaluating
                                                the *best* students from *any*
                                                of the schools. After that,
                                                it's not given you are comparing
                                                second quartile to second
                                                quartile or, if you are, what
                                                exactly that means.
                                       \_ Of course the average MIT student
                                          is better. Their incoming scores are
                                          higher on average (as you state).
                                          However, for same level of
                                          achievement I find Cal students
                                          better than those from, say,
                                          Stanford. Also, I hired a guy from
                                          Caltech as smart as all hell but who
                                          is a terrible employee who has to
                                          be told what to do all of the time.
                                          He's been close to fired several
                                          times now for incompetence. There
                                          are other ingredients to success than
                                          being book smart.
                                          \_ I found Caltech grads to be
                                             impractical (in the sense that
                                             they spend too much time arguing
                                             over and working on the optimal
                                             thing rather than the good enough
                                             thing).  They are very good once
                                             you've slapped them around enough
                                             to break them.  Small sample size
                                             of only 2 though, so definitely
                  \_ I guess it depends what you mean by "better school".
                     I think Cal was a lot of work for minimal reward. By
                     that I mean not that the rewards are small, but that
                     the work was large. It would have been easier to go
                     to "lesser schools", learn less, and do less work.
                     Heck, the main appeal behind Stanford is not that it
                     is "better" but that you can do less and still get
                     a 3.2+ GPA while also having a name on your resume
                     that people care about (and fewer alums from that
                     school in the workforce because of the size).
                     However, you pay $100K+ for that honor.

        of the array B during this pass as well.  Pass 2: starting at the

           the max after the min.  The sequence will occur between the min

12/8    When people say null string or empty string in C, does it mean a char
        pointer that's NULL, or a char array whose first char is '\0'?  Thanks.
        \_ Both, because it's essentially the same. However, I think they
           probably mean the latter. I assume you mean a pointer pointing
           to NULL, and not a pointer which is NULL, which makes no real
           \_ What's I'm thinking is that for "char *str", it can be either
              "str == NULL" or "str[0] == '\0'".  So you're saying that for the
              former, there is no string; and for the latter, there is a string
              but it's a null/empty string.  Correct?
              \_ Possibly, but if you were to malloc a string and assign
                 its lvalue to *str's rvalue then str==null means that
                 you are checking to see if you lost the rvalue for the
                 str. So theoretically the string could still exist if
                 it hadn't been probably freed and you'd have a
                 memory leak. For the latter if you created an automatic
                 character array the memory stays assigned to str regardless
                 of terminating it at the beginning. There is no way to
                 release the memory for an automatic variable unless you
                 do something really wonky. So neither really checks for
                 a lack of a string. The former checks to see if the pointer
                 is pointing to a string, the second checks to see if the
                 first char of a string is the terminator.
        \_ The latter.  "Empty string" is a better term to use than "null
           \_ I always assumed that an empty string is a string that exists
              but is empty, ie "", and that NULL string refers to the case
              where the string pointer is NULL.  /me shrugs
              \_ Typically you see this as char* p = NULL.
                 p is a char pointer.  p points to NULL.
        \_ If the term uses "string", that means it's NUL-terminated.
           Therefore it means "".  A char* that's NULL is a null pointer.
           But probably prefer "empty string" for clarity.
           \_ You mean a char* that points to NULL. a char* that is NULL,
              well, that doesn't exist. Since an array is passed like
              a char* in C, a string which is "" is essentially the
              same a char* pointing to NULL.
              \_ Err, yeah.  I think you might want to rethink that position.
              \_ What?  The previous poster's explanation and terminology
                 was correct.
              \_ char* cptr = NULL; // null pointer
                 char* cptr = ""; // empty string (== "null string" (?))
                                  // "" is \0 in memory.
                 Those aren't the same. You can deference the empty string.

12/7    Optimization time: gprof shows 310k calls to a certain constructor
        (a very simple, very important object that is often stack-allocated
        into large arrays- eg "MyObject msgs[1000];").  Rather than calling
        the constructor 1000 times, is there a way to have a special array ctor
        that's called (once) and zeroes out the array en masse?  TIA.
        \_ Geezus, why are you constructing 310k objects? Make a static array
           of objects at the beginning of runtime.
           \_ I am, when possible.  It's a realtime system (= no dynamic memory
              allocation) so e.g. several queue objects have to buffer
              about 15k messages statically.  The rest are open to optimization,
              but a specialized array constructor (if it exists) would be nice.
              (nb: by "nice" I mean "not at all critical")
              Oh, and if it helps for those in a similar situation: MyObject
              contains a couple small arrays; it's much faster to zero these out

                 total RAM do you have and what form is it in? And why the hell
                 are you using an OO language for small RTS apps?

                    I'm coming to the conclusion that I can't just define
                    MyObject::MyObject[] ().
                    \_ Yes you can, you can overload new[].
                       \_ Ok, this might be helpful; can you elaborate?  What
                          would the constructor declaration look like?
       \_ If you want the array zeroed out without any object construction
          occuring, there are a few things you can do:
          (1) Create a default constructor which doesn't do anything
          (2) Overload new[] as suggested above to accomplish this
          (3) Allocate the space for the array using malloc or calloc instead
              of new and then use placement new to do the construction.
              Specifically, placement new lets you construct an object into
              a memory location you have allocated yourself.  The benefit of
              this is that your program would only need to spend time
              constructing an object when you want to put it in the array
              instead of when you allocate the whole array.  -emin

            otherwise (see "man setvbuf").  When you pipe foo's output to

            turns on its buffering.  The easiest cure is to create a fake

           transmitting the key is.  Aside from their hard-on for extracting
           (even more) money from consumers by granting themselves new rights
           that don't exist under conventional copyright law, one of the
           reasons content industry execs bought into DRM was that they were
           too technically clueless to recognize that the ``give the user the
           key'' flaw that is inherent to all DRM systems.  The empirical
           evidence of numerous trivially cracked DRM systems (hold down the
           shift key, use a black sharpie on the edge of the CD, etc.), and
           the 20/20 vision of hindsight has made their obvious `Whoopsie'
           clear to them.  The DMCA and the continuing legal onslaught is a
           crass and sorry attempt to use to law to patch over a gaping
           technical hole.
           \_ You sir, are a moron.
              \_ Care to expand on that?  What are the flaws in his argument?
        \_ Use rot26 encryption, anyone who cracks it will be violating
           the DMCA and you can ask the feds to put them in jail!
           \_ Crap!  Merely by reading this sentence I violated the DMCA!

11/11   Simple question I suppose, but this happened to me with an ISP in
        Japan. Have two email accounts set up.  First account has forwarding
        to the second account.  The 2nd account recently set up a vacation
        reply. So mail arrives in first account, is forwarded to 2nd account,
        which in turn generates vacation reply, which the first account gets,
        it forwards that email, another vacation response is generated and
        received, etc, etc.  Pandemonium ensues.  The ISP called it a
        denial-of-service attack and is threatening to cut off service.  But
        this was an honest mistake (2nd account is used by a colleague and he
        set up vacation response on his client without telling me.)  Question:
        would any other ISP (or Soda) have been able to prevent this, or at
        least stop it before it brought down their system?
        \_ a reasonable vacation reply mechanism would implement loop
           detection headers and/or duplicate message-id checks (as should
           any other auto-responder).
           \_ Not to mention keeping track of recipients.  Your first
              ISP should also have some kind of reasonable loop detection.
              Tell them both that the gaijin tech gods have spoken and that
              they should get /<l00 or we'll whip out the black ships. -John
           \- Thanks for the replies.  Should these checks have been
              implemented on server software, client software (maybe there is
              a setting for "reply once"?), or both?
              \_ basic rule of computing: never trust clients, never rely on
                 clients to do the right thing.  your isps are both stupid.
                 \_ Not even a 'trust' question--this is basic mail server
                    config 101.
                    \_ I was making a more general statement about all client/
                       server relationships, not just mail.
           \_ But isn't a vacation responses a separate piece of e-mail
              similar to when the user does a reply, instead of a re-route of
              the original?  How does loop detection help in this case?
              \_ It should not be similar; it should have a Precedence: junk
                 header, among other things.  And as noted above, the vacation
                 program should keep track of recipients.  -tom
              \_ it should notice its own message sent  back to itself and
                 not reply.  this would solve OP's problem.  you are right
                 that this might not help two vacation systems in a volley,
                 but that is caught by not sending vacation notices to the
                 same recipient within some time period, e.g. a week.

11/5    Anyone with biology fu happen to know whether there are any theories

        code for mutation robustness? -- ilyas
        \_ google for exons introns error-correct, e.g.,
        \_ human DNAs are persistent because of the redundancies in it. They
           estimate that over 80% of the DNA doesn't actually do anything.
           \_ isn't this thinking actually being overturned now? I seem to
              recall reading an article in Sci Am or Discover that supposed
              "junk DNA" may not be so junk afterall.
              \_ Ah, okay. Found it. Scientific American, Nov. 2003. Article

           \_ Ah, but if you do that to a whole population of mice, what would
              be the effects on their decendants in a few generations?
              \_ They will create a web site called ""

                    LBL] but anythign is this field will be going out of date.

10/30   How do I prevent variable substitution within double quote in tcsh?
        The manual says I can quote it with backslash but the following
        does not work:  echo "\$ "
        \_ There is no way to prevent variable substitution within double
           quotes in tcsh.  Usually it's easiest to use single quotes;
           failing that, the best you can do is echo "foo"\$"bar".  --mconst

10/28   Gah! HOw do I keep spamassassin's files from putting me over
        quota? I have STFW. I spent a couple hours, actually. I lack
        sufficient clue to find the answer.
        \_ Add a 'rm -f LSPAM' line to your .login.
           \_ What does that do? I don't know of an "LSPAM" file.
              \_ Um, if you never see LSPAM files, never mind.
           \_ Does this mean someone else is using ifile?
              \_ Guilty as charged.
                 \_ Wow.

                bayes_seen@ -> /dev/null

           \_ Hmm. Maybe I'm asking too much, but is there a way to stay
              under quota that doesn't involve crippling bayesian filtering?
              I don't get why I'd be the only person whose bayes_* files are
              going over quota. I just haven't heard what people are doing
              about it given sa's populariry.
              \_ You aren't the only one. I asked for a quota increase.
                 It's not like it's a lot of space.

                 following configuration settings:
                \_ Alrighty. The trouble is answers web-wide are good for the
                   quotas on particular systems. I would like some suggested
                   values for these items (which all go into .spamassassin/
                   user_prefs for others trying to learn from this thread) that
                   are good for soda.

10/21   My digital camera (canon powershot) doesn't have the functionality
        of adding date/time at the bottom right hand corner of every picture.
        And I develop the pictures at Costco and their machines do not print
        date/time at the back of the paper.  I really do not want to use
        software and manually open up each file and add the date/time
        into the pictures.  Too time consuming.  Are there other printing
        services that will print the date on the back of the pictures?  Or
        some software that will automatically add the date in.  Like some
        programs will create thumbnails on all jpgs in a directory and name
        them appropriately.  Thanks.
        \_ I suspect ImageMagick could do this if there's some way to extract
           the timestamp from the EXIF data.  ImageMagick is great for scripted
           image manipulation but I don't know how to extract EXIF data with
           it or any other program. -dgies
