Message-ID: <20141106174852.34691279lbneh3b4@webmail.rawbw.com> And yes, BUUG meetings do go on*, even if you don't see much activity on the web page or email list. Just last month we had one of our meetings where our attendance was 60% BSD developers! Yes, never know who's going to show up (well, I'm almost always there), but various interesting folks and discussions typically take place. *per usual, 1st & 3rd Thursdays Oh, and if one wants to know more about Unix/Linux, and time and timezones on Unix/Linux, and how that's handled, and history thereof, might want to peek back at these: http://buug.org/pipermail/buug/2007-November/002960.html http://buug.org/pipermail/buug/2007-March/002887.html http://www.buug.org/ From Michael.Paoli at cal.berkeley.edu Sat Nov 8 01:37:07 2014 From: Michael.Paoli at cal.berkeley.edu (Michael Paoli) Date: Sat, 08 Nov 2014 01:37:07 -0800 Subject: [buug] No trust path to Linux Mint Message-ID: <20141108013707.21444yxw0ko64q8s@webmail.rawbw.com> No trust path to Linux Mint One of the things from this past Thursday's meeting, someone mentioned interest in Linux Mint. I still find no trust path to Mint, specifically any of the ISO images. I mentioned this earlier to Mint Linux on their release blog comments, and thus far I still don't see a satisfactory answer to that shortcoming. Situation appears still quite the same for Linux Mint. I thus find it hard to take such a distribution all that seriously if they can't be bothered to sign or provide other secure means of authenticating their ISO images. references/excerpts: Michael Paoli Says: May 19th, 2013 at 1:18 am Where/how does one find trusted path to the ISO image? I'm not easily finding any GPG/GnuPG/PGP signature(s) for the ISO file or for secure hashes of the ISO file, nor am I finding https/SSL/TLS CA certified path to linuxmint.com release page giving claimed secure hash(es) of the ISO. http://blog.linuxmint.com/?p=2361#comment-93804 From Michael.Paoli at cal.berkeley.edu Fri Nov 14 12:07:42 2014 From: Michael.Paoli at cal.berkeley.edu (Michael Paoli) Date: Fri, 14 Nov 2014 12:07:42 -0800 Subject: [buug] BALUG: Tu 2014-11-18: Michael Paoli on Rockbox @ Henry's Hunan - 110 Natoma St. Message-ID: <20141114120742.175434adpakv330g@webmail.rawbw.com> BALUG: Tu 2014-11-18: Michael Paoli on Rockbox @ Henry's Hunan - 110 Natoma St. ------------------------------ items, details further below: BALUG meeting 2014-11-18: Michael Paoli on Rockbox @ Henry's Hunan - 110 Natoma St. giveaways (CDs/DVDs, ...)

Meeting Details... Cost/Dining: The meetings are always free, but dinner is not (unless you are our guest speaker, in which case we also treat you to dinner). For Henry's Hunan Restaurant, if folks are agreeable, we'll share and dine "family" style, and split up the costs, and typical cost per person including tax and tip (but not including beverages beyond complementary tea) would be in the $13.00 to $17.50 range, and commonly around $15.00 to $16.50. Cash may be preferred to ease splitting up the check. One can also specifically order the dish(es) one needs/prefers (e.g. for dietary considerations) - and we also commonly order some dish(es) that may meet various dietary considerations) (e.g. vegetarian, non-pork, ...). Please arrive by 7:00 P.M., we expect to order entrees at that time, and may order appetizer(s) and/or soup(s) anytime after 6:30 P.M. ------------------------------ We typically have various giveaway items at BALUG meetings. We'll likely have at least the below plus additional items. CDs/DVDs/ISOs, etc. - have a peek here: http://www.wiki.balug.org/wiki/doku.php?id=balug:cds_and_images_etc We may also be able to "burn" images per request or copy to USB flash, etc. Donations of blank or +-RW media, USB flash, or funding thereof, also appreciated. See the above URL for details (and the inventory (qty.) of what we specifically have "burned" and available on-hand does also frequently change). ------------------------------ Last meeting this year, & 2015 meeting dates 2014-11-18 is our last meeting for 2014 (we'll skip December, as we typically do). For 2015, please note our meeting dates (almost always 3rd Tuesday): 2014-11-18 2014-12-16 2015-01-20 2015-02-17 2015-03-17 2015-04-21 2015-05-19 2015-06-16 2015-07-21 2015-08-18 2015-09-15 2015-10-20 2015-11-17 ... Be sure to check http://www.balug.org/ and/or watch our announcements for updates, location and details, etc. ------------------------------ Got venue? We can use your help on leads (and follow-up) for venue! Certainly feel free to discus on our "talk[1]" list. See also the earlier item[2] on our admin list that gives fair overview of what we're hopefully looking to find as for venue. We could certainly use a venue that works well for speakers/presenters (e.g. projector & screen), can handle fair sized crowds (to 30 or more, ideally to over 100 as we sometimes have), is reasonably economical and consistent across varying attendance sizes (e.g. same location or very close in part of same facility), and where dinner/food/beverages are either available at such a presentation facility, or very close by. IF YOU HAVE LEADS ON SPECIFIC VENUE(s) BE SURE TO DROP US A NOTE!: balug-contact at balug.org - and can of course also mention/discuss it on our "talk[1]" list. And much thanks for leads/contacts, useful ideas, follow-up on that, etc. that will get us to our future venue(s)! Henry's Hunan Restaurant - 110 Natoma St. can handle us well in most regards for dining and up to fair size crowd, but we have no screen/projector nor PA capabilities there, so for talks/presentations, only the less formal, smaller, and without projected "slides" would work there. (But in the meantime, the food there is really yummy!) We also expect to announce any and all venue changes reasonably well in advance (week(s) to month or more), so folks have reasonable time to prepare/adjust and aren't (too) "surprised" and so folks don't have last minute changes sprung on them. 1. http://lists.balug.org/listinfo.cgi/balug-talk-balug.org 2. http://lists.balug.org/pipermail/balug-admin-balug.org/2014-July/001504.html ------------------------------ 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 Nov 20 13:41:13 2014 From: Michael.Paoli at cal.berkeley.edu (Michael Paoli) Date: Thu, 20 Nov 2014 13:41:13 -0800 Subject: [buug] Debian(/Ubuntu/...) reverse dependencies? Message-ID: <20141120134113.20392kdxdducdukg@webmail.rawbw.com> Question came up at 2014-11-06 BUUG meeting, essentially, why for a given Debian (or Debian-based) distribution, has a particular package installed? What depends upon it? I did mention: apt-cache rdepends That's a fair start. Checking a bit further, seems: apt-cache --installed rdepends or: apt-cache --installed --no-recommends --no-suggests rdepends would work very well, but alas, doesn't seem to work as well as one might like. Checking a wee bit further, there's also: apt-cache also has command arguments: dotty xvcg that could be quite useful. There's also package: apt-rdepends Not standard/default part of the basic apt stuff itself, but available package and quite handy. So, with that, something like: apt-rdepends --reverse --state-follow=Installed --state-show=Installed appears quite useful ... but apt-rdepends also has some limitations, etc. Also, aptitude can be qutie handy, notably: aptitude why E.g. for a host that has a wiki (dokuwiki) which depends upon the (apache2) web server, we have: $ aptitude why apache2 i wwwconfig-common Suggests apache2 $ aptitude why wwwconfig-common i javascript-common Depends wwwconfig-common $ aptitude why javascript-common i dokuwiki Depends javascript-common $ There's also debtree - somewhat similar to the dotty capability of apt-cache. Using debtree can produce nice pretty pictures 'n graphs, e.g.: $ debtree --show-installed --show-rdeps --max-depth=0 --no-recommends \ > apache2 | dot -Tpng | display - &
