Twitter https://twitter.com/#!/BALUG_org ------------------------------ For our 2014-03-18 BALUG meeting, at least presently we don't have a specific speaker/presentation lined up for this meeting, but that doesn't prevent us from having interesting and exciting meetings. Sometimes we also manage to secure/confirm a speaker too late for us to announce or fully publicize the speaker (that's happened at least twice in the past six or so years). Got questions, answers, and/or opinions? We typically have some expert(s) and/or relative expert(s) present to cover Linux and related topic areas. Want to hear some interesting discussions on LINUX and other topics? Show up at the meeting, and feel free to bring an agenda if you wish. Want to help ensure BALUG has speakers/presentations lined up for future meetings? Help refer speakers to us and/or volunteer to be one of the speaker coordinators. Good food, good people, and interesting conversations to be had. So, if you'd like to join us please RSVP to: rsvp at balug.org **Why RSVP??** Well, don't worry we won't turn you away, but the RSVPs really help BALUG and the Four Seas Restaurant plan the meal and meeting, and with sufficient attendance, they also help ensure that we'll be able to eat upstairs in the private banquet room.

See the above URL for details (and the inventory (qty.) of what we specifically have "burned" and available on-hand does also frequently change). ------------------------------ volunteering to help BALUG (and add to your resume/experience) Not only can you do useful and cool stuff volunteering to help BALUG, but it can also be a way to gain useful and practical experience, and could also be something to add to or round out one's resume. There a quite a variety of opportunities to help BALUG. Come talk to us at a meeting and/or drop us a note at: balug-contact at balug.org These opportunities may include, among other possibilities: o assist on speaker coordination/procurement, etc. o assist on publicity o chief/assistant cat herder o Linux Systems Administration (e.g. do/assist/learn, with/under some quite experienced and skilled Linux systems administrators). o webmaster, assistant webmaster, designer, graphic artist o archivist/history/retrieval/etc. o and other various/miscellaneous tasks BALUG "ought" to be doing or would be good to do (feel free to suggest ideas!) ------------------------------ Twitter - you can also follow BALUG on Twitter: https://twitter.com/#!/BALUG_org ------------------------------ Feedback on our publicity/announcements (e.g. contacts or lists where we should get our information out that we're not presently reaching, or things we should do differently): publicity-feedback at balug.org ------------------------------ From Michael.Paoli at cal.berkeley.edu Thu Mar 20 07:55:52 2014 From: Michael.Paoli at cal.berkeley.edu (Michael Paoli) Date: Thu, 20 Mar 2014 07:55:52 -0700 Subject: [buug] big/huge directories, standards, Ubuntu, pi, oh my! ... Message-ID: <20140320075552.18951i1cd69abs68@webmail.rawbw.com> So, a small sampling of interesting discussions, etc. from recent BUUG meetings - and yes, BUUG meets again this evening, per usual. :-) 2014-02-20 meeting, among other things, we discussed big/huge directories on Unix/Linux filesytems, that for most filesystems directories only grow, and never shrink, and other interesting bits. 2014-03-06 meeting, among other things, we discussed standards, including POSIX, LSB, Single Unix Specification, some bits of related history, etc. 2014-03-20 meeting - yes, today. Dear knows who will show up (well, other than me) and what we'll discuss, but it's generally interesting. Agenda, what agenda, I thought you brought it? Yes, BUUG is general (Unix, Linux, BSD, ...) discussion, we don't lock ourselves in to particular discussions or presentations or the like in advance. And sometimes quite interesting folks just drop in on us, often very unexpectedly. Oh, and today, also we have Ubuntu Hour Berkeley with us at BUUG from 7:30pm-8:30pm: https://wiki.ubuntu.com/CaliforniaTeam/Projects/UbuntuHours http://loco.ubuntu.com/teams/ubuntu-california/events/ And still have some books/publications to give away: http://buug.org/pipermail/buug/2014-February/004035.html though at present down to one print (Ubuntu) book left, and electronic editions. And I might talk today a bit about Raspberry Pi. Wee bit more details. Big/huge directories - don't try this at hom^Wwork. I should eventually get it more fully written up, but did a bit more testing/experimenting. Biggest directory I've ever encountered ... yet. Took a friggin' long time to create it, and I intentionally targeted slightly larger than the largest I'd ever encountered prior. Just a sneak preview - and this was only part of the run to create it (did it in several stages): $ (cd ext2/d && time perl -e 'my $n=3148166; my $f=$n; my $fh; while ( (stat(q(.)))[7] < 111738880 ){link($f,++$n)||(($f=$n) && open($fh,q(>),$f) && close($fh))||die;};print("$n\n");') 6986086 real 12054m54.306s user 1m26.261s sys 11982m29.116s $ And how big?: $ ls -dls ext?/d 109550 drwx------ 2 michael users 111738880 Mar 20 05:42 ext2/d $ Anyway, more on that later. Oh, and standards, standards: "POSIX" / Single Unix Specification / The Open Group Base Specifications Issue 7 / IEEE Std 1003.1, 2013 Edition: http://pubs.opengroup.org/onlinepubs/9699919799/ LSB: http://www.linuxfoundation.org/collaborate/workgroups/lsb/ From itz at buug.org Thu Mar 20 09:15:22 2014 From: itz at buug.org (Ian Zimmerman) Date: Thu, 20 Mar 2014 09:15:22 -0700 Subject: [buug] big/huge directories, standards, Ubuntu, pi, oh my! ...

Would be nice to do something so it could be done with very easy interface - like nothin' but some LED indicator(s). Insert USB - have some file or the like that tells it what image to put on it, LED(s) give status on progress and such. No keyboard, don't even need text display, don't need network, SD can hold quite a number of ISOs and the like easily enough, could even write up to two usb flash drives at same time without need for external hub. Could even have one LED and just flash in Morse Code. Hmmmm... maybe small simple LCD display (one line of text or so) would be more human-friendly, yet very low power. Anyway, I'm still thinking about the interface designs - something to show status, and simple yet goof-resistant ways to put stuff on USB to tell it what to do (e.g. "magic" string and some indication of what to write to the USB). Doesn't need any "input" other than USB sticks and the SD it boots and runs from. > From: "Ian Zimmerman" > Subject: Re: [buug] big/huge directories, standards, Ubuntu, pi, oh my! ... > Date: Thu, 20 Mar 2014 09:15:22 -0700 > On Thu, 20 Mar 2014 07:55:52 -0700 > "Michael Paoli" wrote: > >> And I might talk today a bit about Raspberry Pi. > > Interesting, I just thought about it yesterday.
