9/19    What's the easiest way to replace text strings in a binary file?
        I have a feeling that sed can't be used with binary files...
        \- uh you can try emacs. anymore is probably beyond the scope of wall.
        \_ perl -pi -e 's/foo/bar/g' is probably pretty safe;
           add in a -0777 first if you want to be paranoid
        \_ If you're replacing same-size strings, any hex editor will do.  If
           you're shrinking them, then fill with spaces.  If you're growing,
           you might break something if it's an executable or some self
           referenced data file like a zip.
           \_ spaces?  Why not null chars?
              \_ because code accessing those strings may run into trouble
                 with nulls/

9/16    Related to the evaluation question below, how do you answer the
        interview question "what are your weaknesses"? I've gotten that
        from two different guys at the same company before and it was kinda
        painful because they really, really pushed deep on that question.
        \_ Do like they did on The Simpsons. "I'm a workaholic."
        \_ "My weakness is I refuse to work with doofuses who ask
           lame-ass questions like 'what are your weaknesses'?"
        \_ "I survived UC Berkeley where we kill the weak and eat their still
            beating hearts!  I have no weaknesses, little man!  What pathetic
            'school' did *you* go to?"  It doesn't really matter what you say.
            You're dealing with some doofus and every answer can be turned
            into the wrong answer.  You can say something like, "well my
            girlfriend sometimes gets upset that I'm such a take-charge
            gung-ho kinda guy when we make plans but she always has fun!"
            All answers are stupid, just try to avoid giving an axe-murderer
            answer.
            \_ These were the two highest-ranking tech godfathers at this co.
               If you had said that "take charge" answer they'd scoff and
               make you give a *real* weakness. Oh well, fuck 'em I guess.
               One of them spent about half the interview on that question,
               and the rest questioning my "passion for engineering" and why
               I'm an engineer etc... unfortunately rather close to home tho.
               \_ I'm 28 and a software engineer, and I want to work with
                  "good" people more than get a salary.  The fact that they're
                  asking these meta-questions might suggest that they're
                  concerned with what your life goals and attitudes are,
                  have you figured it out.  It's just a job, but you
                  spend half your life at work, so I can see why.
                  \_ No, it means the interviewers are lazy and/or
                     inexperienced.  However, your answer is correct.  -John
               \_ I've had the exact same thing happen to me when I gave some
                  clever variation on the 'work too hard' line.  So I told him
                  I'm smart and have low tolerance for people who are
                  intentionally stupid.  Not stupid people, but people who
                  play dumb for political or other reasons.  I got an offer,
                  but I don't think that had anything to do with it.  I think
                  he was just filling time and feeling self important.
                  \_ yeah. btw i needed *3* weaknesses. well, it actually
                     taught me how to be better prepared for interviews.
                     it's all about attitude.
                     \_ 3?  That's fucking crazy.  "Gee, I'm not that flawed".
                     \_ a more specific question would have been
                        "tell me 3 things your co-workers hate about you"
        \_ the standard answer is: "I work too hard...". not inspiring or
           original, but it works. if yer just outta skewl, mention that
           you spent all yer time in the computer lab. don't mention the
           B.O. problem.
        \_ a good manager (read, the kind of manageryou want to work with)
           knows that different people are happier doing different things.
           Questions like this aren't ment to be ducked.  What they are trying
           to get at is "What sort of stuff do you do poorly?  What sort of
           stuff do you just not enjoy doing?"  Yeah saying something like
           "I goof off half the day and get everything done late" is stupid
           but a real answer like "when I'm working on a project with a bad
           debugging environment my productivity drops really bad" would,
           say let them know you might do better at being a server coding
           person that working with some proprierty scripting system that
           doesn't have real tools.  They want people, not pretend workaholics
           who will leave in disgust six months later because they treated
           management as roadblocks to be worked around, and somehow, gee,
           that made work a nightmare.
           \_ This is probably true but I've never had the pleasure of working
              with a "good" manager. Then again, I'm in civil engineering, not
              coding. The consensus among those I've talked to is that the
              weakness question is the interviewer getting in an early stab at
              establishing pecking order. They, after all, will never have to
              answer such a ridiculous question of themselves from you. If you
              want the job, have your canned answer ready and don't be worried
              that it's not exactly honest. They're not looking for honesty.
              They're looking for you to subvert your ego for the "team". You
              may, however, want to consider whether this is the sort of
              situation where you'd like to work, if you have a choice in the
              matter. In the current times, nobody in my business really has
              much choice.
              \_ I had a good manager once.  I can barely remember what it was
                 like....  Maybe we had the same one since I think there's only
                 about 3 out there.

9/13    I'm trying to download legal mp3s using
        wget -nc -r -l3 -A"*.mp3*" \
'http://www.subpop.com/scripts/main/multimedia.php?key=format&value=mp3
        but it doesn't work. I haven't used wget much; what am I doing wrong?
        \_ maybe you can set your refererr value to something innocuous like
           'Netscape 4', read the wget manpage.
           \_ you have "referer" and "user-agent" mixed up.  But setting the
              user-agent value in addition to the referer one is a good idea.
        \_ Your ISP probably blocked all mp3 files because they have the evil
           bit set.
        \_ the host probably disallows direct linking to files.  If so, you
           need to specify a referer.
        \_ It wasn't referrer or user-agent, but rather something about
           the option I think.  At any rate, I parsed the page manually
           and came up with a list of hrefs to d/l, and that worked fine.
           Thanks for the help.

9/12    I can't FTP into OCF from behind firewall/router.  Can anyone tell
        me what's wrong? -stupid newb
        \_ block ephemeral port and doesnt understand ftp PORT cmd? --psb
        \_ use FTP in passive mode.   ftp -p
        \_ As the above says, use passive mode.  Ftp's normal mode is to
           have the server try to connect back to the client so the client
           becomes a server of sorts.  This attempted connection smacks into
           your firewall and thus ftp in it's normal mode fails.  Passive
           mode doesn't do that so you can ftp from behind firewalls.

           more compatible client. anyway, miranda probably doesn't work

              the same when you guys are in the similiar situation.
              In any case, I am leaning toward installing Centericq
              on my shell account instead of dealing with this problem
              directly.  For those who actually knows what I am talking
              let me know how  you guys deal with this. Thanks

8/27    This is a question for Imaging gurus.  I have a few JPEG
        files which I'm not able to view on my PC.  However, I am
        able to view the thumbnail of the pic in Windows Explorer
        in XP.  When I try to load it in 'xv' on unix I get the
        following errors.  The image is located at /csua/tmp/photo18.jpg.
        Is there any way to fix these JPEG errors?  Thanks for any
        help. -  madhav

           \_ Thanks.  I tried on my work PC (W2K) and it seems to open the

        \_ Where did the image come from?  If it is from a digital camera,
           it is likely that they did a "smaller+regular" image trick.
           Basically they stored a smaller version of the image at
           the front to allow faster preview inside the camera.  Maybe
           "xv" just does not handle this case?  (Sounds like John's
           assumption of having "two Start Of Image" may back this up.)
           \_ The image came from my Sony Mavica CD-200 digital camera.

              1 in 25-30. -madhav
           \_ I did a bit of digging, and apparently some jpeg file formats
              like SPIFF use SOI markers to indicate that the following
              information is format-specific.  Some decoders don't understand
              the tags which follow the additional markers, and just look
              at the SOI bits themselves.  Page for SPIFF is at

                    and then pipe that to sh or to a file and then edit and
                    runthe file. obviously be as careful as you need to be.

        (readonly) files, such as the mirror of some web sites, in one file.

        tar, any other way to achieve this?

           Write some scripts then GPL and share them so we can all enjoy the
           fruits of your labors.  You stand on the shoulders of giants!
                \_ tar can save a small amount of space by packing the files
                   in and not wasting as much unused space at the end of each
                   file
                   \_ Huh. I'm no cs guy, but I've generally found uncompressed
                      tar files to be larger than the directories they
                      reproduced - particularly when a large number of small
                      files were in the directory. I had to do a lot of this

6/3     I want to have apache run fault-tolerantly across two web servers.
        I've found http://eddie.sourceforge.net but nothing else that seems to
        be appropriate and free. I don't run Linux (Solaris 9, actually). Any
        suggestions? ok tnx
        \_ store the content on a central system and serve it out using
           nfs to the to systems. Then use dns round-robin or an l4 switch
           (load-balancer) so that if either one of the systems goes down
           you auto fall over to the other one. If nfs is two slow, ssh-rsync
           the content to the two systems periodically.
           \_ isn't the NFS server the weakest link here? also, i'm not
              currently running NFS and would rather avoid it for
              security and complexity reasons. but if this is the easiest/
              most stable way, then i'll look into it.
              \_ NFS is the weak link. Do an ssh-rsync from a third machine
                 or barring that, have one rsync to the other.
              \_ roundrobinDNS is only an answer if the goal is load-balancing
                 if the goal is 100% uptime, round-robin DNS is an anti-answer
                 \_ what is the answer for 100% uptime?
                 \_ dns round robin with small ttls will work pretty well
                    for a small-ish site.
        \_ Did you want just the webserver fault-tolerant or the whole system?
           What are your resources like and what factors are most important
           to you?
        \_ NFS isn't a weak link if it is a NetApp. The real question here
           is what the budget is. There are even appliances to do this. As
           the above poster says, what are the factors here? Does
           performance matter and so on.
           \_ Budgets are largely frozen. The alternative is downtime (which
              is what has been going on the past 10 years). Performance isn't
              an issue, I'd just rather not get calls if a machine dies.
              I have 3 E250's to work with. They also do mail and DNS... I
              figured I'd start w/ balancing http and move on from there.
              \_ Look into load balancing with Apache mod_proxy.  Simple
                 to set up, and you can do more interesting things for
                 heartbeat.
        \_ Take a look at putting a web-cache in front of your http servers.
           With squid you can set it up so that it fetches pages from your
           http server when it doesn't have them and then serve them out to
           clients.

        Freelancer is from the Elite/Wing Commander genre.  It attempts to
        capture the Elite be-anything-you-want (trader, miner, bounty hunter,
        etc) feeling but you're mostly stuck on the single player main mission
        path to the end.  You can diverge and ignore it relatively early if you
        want but unless you already know what you're doing you're better off
        following the pre-chosen path.  Space combat is lacking.  All enemy
        ships appear to use the same AI routine.  There's no radar, only a
        bunch of red arrows around the outside of the HUD showing you the
        general direction of targets but not distance.  The UI has numerous
        annoyances like this.  Play time of main mission: 17 hours, 33 minutes.

           \_ Emin, were you a part of Kubi's group?
                    \_ OceanStore is a great project but it has different
                       goals.  DIBS is designed to provide a way for people
                       to exchange files for backups in a secure, robust
                       way without requiring a central authority. -emin
                 \_ DIBS stores an MD5 hash for each file and does a full
                    backup of any file which changes.  Rsync is not used
                    because DIBS uses encryption and erasure correction
                    coding and that is difficult to combine with rsync.
                    Also, DIBS is peer-to-peer while rsync requires you
                    to have accounts on both ends.  -emin
                    \- yeah i have some limited familiarity with oceanstor
                       but again for something lightweight i am curious
                       about this dibs thing. we hacked up something we
                       call the "storagelocker" with ssh keys and some
                       other access control technology and a big perl
                       script ... it works ok as a palce to write and
                       recover a bitstream but it would be nice to have
                       some smarts to reduce the traffic volume.
                       BTW, does anyone know if the hummingbird fs
                       was ever released and what performance stats
                       look like? --psb

                          is what you are looking for.  The way I use DIBS
                          is to put links to everything I want backed up in
                          a special directory and DIBS automatically and
                          incrementally makes backups to other machines. -emin
                                \- ok i will analyze it and let you know
                                   if i incorporate it into a front end

                 DSP group at MIT.  I work on DIBS because I think it's
                 cool; the stuff I do for "research" is much different. -emin
        \_ Haven't companies been storing backup tapes or disks at separate

12/9    How do I make the output of "tar cvfz some-directory" deterministic?
        My guess is that tar is putting some kind of header in the tar file
        which contains the date.  I ask because I don't want to send a tar
        archive to be backed up if it hasn't changed since the last time I
        tar'red up 'some-directory'.  Thanks
        \- i dont think you can do that, but you can use "find | tar".

              get $ to be treated as a regexp character. leave the parts
              where you want the shell vars to be expanded be unquoted.
              This may/will break if you have $ or spaces in the contents of
              the shell var [in which case you may be doomed with csh].

                 although a speed check would be interesting.
                 more generally sed -n 'X,Yp' will print out the inclusive
                 range from [X-Y]. On a big file this may be slightly better
                 although perhaps not a real big deal on mondern machines:
                 sed 'Xq;d' ... you do get more "sed intimidation points"

10/21   Just an idea-- what do you think of a sort of "follow" command
        for tcsh or bash.  Idea being
        % mv foo.bar /some/really/long/dir/path
        % follow        # cd to /some/really/long/dir/path
        \_ try replacing "follow" with
           % cd !$
        \_ cd !$
           \_ Thanks, I knew I wasn't that creative.
              \- more interesting in a global and directory-specific
                 history stacks. ok tnx --psb
              \_ pushd !$
        \_ There are also times when I do something with a file, and
           then want to go to its directory, e.g.
                % mv oldname /new/directory/newname
                % cd /new/directory
           So in t?csh, I have 'there' aliased:
                there:   aliased to cd `dirname !-1$`
           -geordan
           \_ naughty geordan.  'cd !$:h', or in this case 'cd !-1$:h'
              --scotsman
              \_ Not necessarily -- the reason brg and I chose this method
                 was for the case that /new/directory/newname might be a
                 directory itself.  So you'd use 'there' for the general "I
                 want to go to the last directory I specified." -geordan

           adds to (rather than clobbers) file descriptor 1.
           \_ maybe because you can sorta kinda think of & as somehow like

              completely random. > and < existed pre-UNIX, I think, and in any
              case are the most arrow-looking characters in 0x20-0x7F ascii.

        the average unix user takes for granted.
        \_ Unix for the Impatient

           that would help.  Or take a class on web page thingy
           (make sure it's shell script + CGI  instead of Frontpage + IIS).
           That will get him started. The rest of it is just force

           not afrad of asking questions without be flamed.  Unix crowd

10/17   Is there a really easy way to forward all port 80 packets to another
        machine? I want to migrate my web (but not mail/smtp/etc) packets to
        a new machine. I don't want any sort of HTTP redirects because I want
        the transition to be "seemless". Does my question even make sense?
                              \_ seamless
        \_ Any firewall software can do this.  Or you can point the DNS
           name at your new web server and use MX'es to keep the mail on
           the existing server.  Or use mod_rewrite.  -tom
           \- writing a generic "port forwarder" to listen on localhost:tcp/###
           and fwd that to A.B.C.D:### is pretty straght forward programming
           exercise. in fact it is possible ssh can do it for you. i have a
           tool i suppose i can send you which forwarded the pop protocol
           but it should work for WEEB by just changing the port number.
           [all WEEB is tcp, right?]. i seem to remember after looking at a
           breakin there was some crackerware to do this too. --psb
                                  \ are you calling nc "crackerware"?
           \_ This is what I was going to do. Either this or just use ssh to
              do the forwarding until I complete the migration.
              do the forwarding until I complete the migration. But I was
              hoping that someone had already written something (or gotten
              netcat to work as such) so that I don't reinvent the wheel...
              and don't have to worry about implementing error handling and
              so forth.
        \_ DNS!  Why does no one use DNS for this stuff?  The world wasn't
           meant to be hard coded IPs.  They made DNS for a reason.  You don't
           need clunky firewall kludges if you made proper use of DNS.  You
           wannabe sysadmins are getting more dangerous by the day.  Please
           tell me this isn't a commercial site.
           \_ because dns wont forward port 80 packets.  DNS will send all
              packets to that hostname elsewhere.  This is why a smart admin
              will point several names at the same host, each name for each
              service on the host, and then they can move the ip in the name
              for that service without affecting the other services.  I.e.
              csua www service is 'www.csua',  not 'soda.csua' (even those two
              names point to the same IP), so we can move www service if
              necessary without screwing other services.
              If you weren't so smart, firewall-NAT /packet forwarding/
              is your only option. -ERic
              \_ Thank you for the description of "proper use of DNS" as
                 mentioned above.  Anyone who doesn't know that DNS doesn't
                 forward packets needs to give up the root shell.
           \_ DNS switches are not "seemless".  Even if you have your TTL set
              properly, there is a whole world of improperly set up DNS servers
              (and microsoft DNS clients that mad-cache) that will not get up-
              dated the instant you want them to.  (Of course, just leaving the
              service up at site 1 for a while is probably better than port
              forwarding everything with good ol' nc  -The SysAdmin.
              \_ Gosh, you mean you actually figured out how to do a seamless
                 service migration with DNS?  Wow.  That was hard, huh?
           \_ 1) You are a dumbass, as everyone else already pointed.
              2) Even if what you said were correct (which it isn't), have you
                 considered the possibility that some people might be hard-
                 coding the IP's?
              \_ 1) No one said any such thing.  Learn to read.
                 2) It's correct and anyone who hard coded the IP's is a total
                    moron at step zero and shouldn't have root which was
                    already addressed earlier.  If you could read, you'd have
                    read that, too.

10/11   Stupid unix question.  I have encounter problem like this quite
        often and don't know how to deal with it.  Let say, I am trying
        to rename all the file in a directory, which the new filename
        is actually based upon the old filename except the filename
        extension...  something like
        mv *.aaa *.bbb
        or, in recent case, I am trying to convert whole bunch pdf files
        to text using ps2ascii where i need to supply both input and
        output filename, which is only differ in filename extention.
        So far, i can only do so in 2 steps, using sed/awk and a temporary
        file.  Is there anyway I can do that in one single command?
        I have tried using find with the -exec, but never get it to
        work.  Thanks                   kngharv
        \_ not great, but:
           bash -c 'for i in `ls *.ps*`; do ps2ascii -o $i $i.txt; done'

        \_ in bash:
           for f in *.ps; do ps2ascii $f ${f/.ps/.txt}; done
           -abe

            \_ not working: f: Undefined variable.
        \_  I don't think that was a stupid question. Thanks for asking!
        \_ For all file rename it is good to use shell command like friend
           above say.  Using shell command best way renaming many file at once.

              are various ways to do this using 'dired'.

10/10   I just upgraded to a new version of FreeBSD and I messed up
        when using mergemaster. I now have none of the users from
        my old system (except root), but all of their directories
        still exist. I backed up my old /etc directory, so I have
        all those files...is there a way to get those users back
        without having to formally add users again? Thanks.

           \_ Hey idiot it can be a noun in certain usage.  For instance
              in the sentance "The most popular open source unix available

              Oh and the plural would be unixes.

9/9     Let's say I am writing a multi-threaded email client and I want to

        all elements and if this thing is supposed to scale retrieving all
        messages when changing a sort order will not work. How do real world
        mail clients or applications in general deal with this?
        \_ you only fetch the headers and sort based on that info...

                 i change a sort order..." which makes more sense... all you
                 need to do is before you resort check if there are new
                 message headers, if so then add them, THEN resort. some

                 for new messages, then resort by date or subject. -shac

                           (avoiding) retrieving all messages because there
                                can be a lot of them and if there are many
                                users there goes the neighborhood. I can't

8/26    How do I prevent a particular host or user from having write acess
        to an NFS mounted disk?  There is some rogue process tring to fill
        up my disk, and I haven't been able to block it.  I've tried
        variations on
        \_ what server os?
        \_ you can prevent a certain host from writing to a volume but you
           can't prevent a user from writing if the file system has been
           exported in read-write mode to that host.
           \- actually there is kind of a hairy way to do this with
              some experimental work on nfs filter layers. the work
              involves some extensions to the *_quash routines.
              while it is experimental, the people doing it really know
              what they are doing ... however this is probably one of
              those cases where "if you have to ask, this 'solution' isnt
              for you". if this is you really important you can talk to me.
