1/10    I don't understand why everyone's getting worked up about North
        Korea pulling out of the non-proliferation treaty.  They have poor
        engineering skills so there's really no chance of them developing
        nukes anyway.
        \_ that black dude said they already have nukes.
           \_ yeah, whatever.
           \_ Right, I heard months ago that they had nukes, but was think-
              ing "How the hell did they manage that? They don't build any-
        \_ the new "cuba"
        \_ Pakistan, a country with a much smaller defence budget,
           managed to create it's own nukes.
           \_ with the help of South Africa

        \_ that rules.
             \_ but how often does it update?

                \_ ha ha.
                \_ You probably put something in right as someone deleted
                   the original.  Seems to work OK now.

1/11    Can someone point me to the requirements for a system user on
        RH linux (e.g. "can't start with a number").  I would have
        thought this easy to find on google, but i failed.
        \_ FreeBSD's pattern is [^[a-z0-9_][a-z0-9_-]*$]
           you can probably do a bit of testing with that and see
           what happens.
           \_ sorry i'm not great with RegEx; does that say the the
              first character CAN be a number in bsd? 'cause it can't
              in RH linux.  (and i've never seen it in bsd-land).
              Also, that doesn't specify a max length.
              \_ RTFM man useradd or equivalent on RH
           \_ I don't even think that's a valid regex.
              \_ Seek greater regex fu, grasshoppa.
              \_ It isn't. the ^ means invert the pattern, which isn't what
                 the guy is going for.
                 \_ If you read it as /.../ instead of [...], it makes sense,
                    but could more easily be done as a perl re:

1/11    Just got notice from AT&T that they're sending me a new cable
        modem (for free) - was wondering if anyone else got this, and
        why?  What has changed in the technology that makes them want
        to do this???
        \_ DOCSIS Data over Cable Service Interface Specification.
           They can do diagnistics on new modems that they can't do on
           older ones.  do you lease your modem from ATT? What is it
           $10/month? You can now buy modems everywhere for about $100.
           Oh, if you use for email, get ready to change
           to I sure do appreciate the CSUA..
           \) Cox bastards were charging me $15/mo. So I go out and buy a
              linksys for $50 (ROI <4months), and it works, except I lose
              my csua connection whenever I leave for >10 minutes.
        \_ They changed mine a long time ago.  As far as buying vs. renting,
           I rent because if you own your own and there's a problem the first
           thing they do is tell you your equipment is the problem and hang
           up on you.  Also if it breaks or there's upgrades or whatever, they
           replace it.  I just want my net to work and I'm willing to pay a
           few extra bucks a year for it.
           \_ I bought mine because it was $10/mo. Then they actually reduce
              it to $5/mo rental. Bastards.
        \_ You know why they can arbitrarily change your email address
           and charge you modem-rent? Because in Japan, they get 100Mbit
           connections to the HOME. And 12Mbps DSL costs $20/month.
                \_ yeah but you have to pay in soiled underwear
           \_ Never heard that before. urlP.

1/11    A power outage caused my LINUX computer to crash and fsck can't fix
        the disk because of a bad superblock.  I tried everything in
        the fsck and e2fsck and nothing fixes the bad superblock.  Any
        suggestions for fixing things or partially recovering data?
        \_ superblock is repeated every 5000 blocks or something like that.
           you can use some tool (something like mkfs... ask MOTD for detail)
           to get a list of it.  Chances are, you will have a working
           superblock.  Then, you use fsck manually specify the superblock
           you just found.  I personally has gone though this many times, and
           felt that Linux is a lot more fragile than I would like because
           of this reason.
        \_ Ok, not trying to start another FreeBSD vs Linux flame war but
           somebody has to ask.  Did Linux people wrote they own filesystem
           or did they borrowed heavily from *BSD?
        \_ sometimes, mke2fs creates backup superblocks? did it?
           also, I think the ext3 file system is more durable (next time)
           \_ fsck -b 32 (see man pages) Or use a journalled file system
        \_ Sometimes you can mount bad filesystems read-only and extract
           data.  I was able to do this on a FreeBSD partition with hard
           errors and extract a fair amount of data before the disk
           stopped responding altogether.  YMMV.
        \_ Just wondering, were you using ext3 or any of other journaling
           file systems at the moment?
        \_ Oh dear, another person learns the hard way that linux isn't
           production quality.  Eventually you kids will figure it out and
           move on to real OS's with real file systems or you'll stop putting
           useful data on bad OS's, at least.  No one ever think it'll happen
           to them....  Ext2 is a POS.  Ext3 is a POS+bad journaling.  Do not
           trust any valuable data on these filesystems.  Valuable means
           you wouldn't /bin/rm it yourself.  My cheap ass employer puts many
           many terabytes of very valuable data on ext2 with no backups.  We
           lose data all the time on those systems but not on the real ones.
           \_ My brother-in-law started a new job, sort of night-watchman
              for their computer systems.  A power-outage caused
              crashes (UPS wasn't regularly tested) Only later did they
              find data had been corrupted.  Something to do with the
              type of cheap linux disk and cache flushing or something.
              \_ is there a semi-formal discussion of this anywhere?
                 something you can point the money/management people in
                 company to?
           \_ Please give some examples of better filesystems.
                \_ These people sound like FreeBSD bigots.  I bet they have
                   UFS in mind.  Still, not even UFS will save you from a disk
                   \_ No, but ext2fs at least is by default mounted async b/c
                      of the slow metadata updates (rm -r/tar x taking forever)
                      Async + power outage = major fs problems.  If you mount
                      sync, your performance goes to shit.  Ext3 and FFS +
                      soft updates both solve this problem.
                  \_ No.  I wrote the "Oh dear" comment.  I don't have *any*
                     Freebsd systems.  You sound like a linux zealot defending
                     your beloved POS at all costs with no sense.  Ext3 is a
                     huge joke.  When you take a POS ext2 system which will
                     lose data on an idle system and "bolt on" a crappy wannabe
                     \_ Please give examples of better filesystems
                     pseudo-journaling system like Ext3 you don't get a JFS,
                     you get a crappy ext2 FS with crappy bolted on journaling.
                     His disk was probably bad *before* the disk crash and he
                     didn't know because he hadn't power cycled in months.  He
                     likely didn't have a disk crash from the power outage. He
                     probably had an ext2 barf all over his disk earlier and
                     it didn't show until he needed to get that super block.
                     \_ Ok, I'll bite. What makes ext3 a "pseudo journaling"
                        file system and why its journaling is considered as
                        "crappy bolted on journaling"?
                     \_ Please give examples of filesystems better than etx3
                        \_ reiser?
                        \_ vxfs.  wafl.  xfs (real xfs)
                        \_ if you're talking about Linux file systems, ext3
                           is the safest choice and it is "blessed" by the
                           leading kernel developers. I disagree with the rants
                           about ext2/ext3 here. We used ext2 at work. We had
                           power outages. Did we have to wait for hours for
                           fsck to complete? Yes. Did we lose any data? No.
                           Ok, maybe we were lucky.  Now we're using ext3. We
                           had no problems with it whatsoever. We never had
                           to fsck a file system, never lost any data. And
                           by the way, vxfs is available on Linux too,
                           as a part of Veritas foundation suite, if you'd
                           like to use a "real" file system..
                           \_ Thanks, I like your practical viewpoint.
        \_ If your data is important to you, you will use RAID. Disk failures
           happen under any O/S and there is nothing you can do about it
           but use redundancy. Anyone who tells you otherwise is full of crap.
           \_ I wouldn't stop at RAID.  You need to backup your RAID too.
              A single RAID box could be taken out by a power surge.

1/11    So much for conservatives saying the democrats are the ones
        who are "soft on crime":
        \_ He's a RINO and asshole.  He is under invetigation by the Justice
           Dept.  He's a Daley democrat with an R after his name.  Conservatism
           is about ideas - not politicians.
           htit's own
        \_ Here is a man who has no political future.  In his tenure,
           13 innocent people were nearly killed by the state, but
           exonerated.  He's asked for death penalty reform before,
           but was denied by the legislature.  Regardless of how you
           feel about being "soft on crime", he's obviously doing
           what he thinks is right.
           \_ And trashing the rule of law and will of the voters of the state.
              Investigation in borderline cases might be a good idea, but carte
              blanche commutation is reckless and hurtful--now families of
              people horribly murdered will have to wonder for years if the
              killer of their loved one will somehow get out of jail.  Nice job
              \_ their death sentences were commuted w/o possibility of
                 \_ Again: See the case of Robert Lee Massie here in CA for an
                    example of how this can be a problem.
          \_ several people on Illinois death row were found to
             be innocent and released.  I bet there's at least one
             more innocent guy on DEATH FUCKING ROW.  that sucks.
              \_ As governor he has the right to commute sentences.  How is
                 that trashing the rule of law?  As for the will of voters
                 in the state: a "hard on crime" constituency should not
                 be able to create a system to kill people of dubious guilt.
                 \_ The people of Illinois have decided that they want to have
                    the death penalty applied in their state.  By commuting
                    *all* of the death row convicts, he has ignored their will.
                    If he were that interested in the issue, he should have
                    issued an executive order to have all of the death row cases
              \_ Bummer--they got convicted by a jury of their peers, and then
                 didn't get the conviction turned over in any of the (likely)
                 many appeals.  Color me unimpressed.
