Advanced file systems
by John Lange 04 Jan '05

04 Jan '05

Hello List. Does anyone know of a file system that supports dynamic meta-data and file versioning? By meta-data, I mean information about the file. Typically this would be things like created/modified date, etc. but I would like to be able to store other meta-data, perhaps things like "customer id" etc. By versioning, I mean, when a file is modified or deleted the previous version is automatically saved. I would like this to be a file system available under Linux but I am curious to hear of any file systems that are like this. Regards, -- John Lange

[Posted to man.unix.general and other news groups] ------ Forwarded Article <crerkb$6pd$1(a)canopus.cc.umanitoba.ca> ------ From gedetil(a)cs.umanitoba.ca (Gilbert E. Detillieux) The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, January 11. The meeting topic for this month is as follows: RAID on a Budget We've all heard people talk about disaster recovery and business continuity plans. One of the steps to building a strong IT environment is using redundancy to reduce the downtime a business could face at the worst possible time. John Schulz will be presenting a overview of various RAID (redundant array of independent disks or redundant array of inexpensive disks) solutions he has worked with. The focus will be on low to mid end OEM or "build your own" solutions where cost per GB is an important factor. The group holds its general meetings at 7:30 PM on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ********************************************************************** Please note our new meeting location: The IBM offices, at 400 Ellice Ave. (between Edmonton and Kennedy). When you arrive, you will have to sign in at the reception desk, and then wait for someone to take you (in groups) to the meeting room. Please try to arrive by about 7:15 PM, so the meeting can start promptly at 7:30 PM. Don't be late, or you may not get in. Limited parking is available for free on the street, or in a lot across Ellice from IBM, for $1.00 for the evening. Indoor parking is also available nearby, at Portage Place, for $2.00 for the evening. ********************************************************************** For more information about MUUG, and its monthly meetings, check out their Web server: http://www.muug.mb.ca/ Also note that MUUG maintains two mailing lists, called "muug-announce" and "roundtable".

Print Accounting Software
by Scott Wellman 09 Dec '04

09 Dec '04

Hello Everyone, I would really appreciate any advice or recommendations regarding a printing issue I am dealing with. The situation is this; I work at the University of Manitoba and every year we have a huge number of new and repeat students. Additionally, the demands for our printing resources are high. What I am looking for is a print accounting package that would run preferably on either OpenBSD or Fedora. Some of the features that would be helpful are: 1. Support for Linux, Mac OSX, and windows workstations 2. Some type of charging system for each page the student prints. For example, 10 cents a page 3. Web interface for management purposes Once again, any recommendations would be greatly appreciated. Thanks in advance Happy holidays Scott Wellman University of Manitoba

The meeting topic for this month is as follows: Migrating from Red Hat to Debian Linux Red Hat/Fedora has much to recommend it, but if you're looking to try and expand your horizons a bit, Debian's a good candidate to try! Scott Balneaves, from Legal Aid Manitoba, will give a quick overview of installing Debian, the different "flavours" (i.e. stable, testing and unstable), and an overview of the commands and files you're used to on Red Hat, and where to find them on Debian, so you can get yourself kickstarted with a little less reading.

Re: [RndTbl] Convert time in seconds to date in bash?
by Kevin McGregor 07 Dec '04

07 Dec '04

Gosh, I don't think I've ever been compelling before! I perhaps could have provided some context around my question. I have several log and data files (e.g. Squid's access.log; arp.dat) which store the timestamp as the usual seconds since the epoch. I was looking for something quick and dirty which would let me list the files with the timestamp converted to something readable for a quick look as to what happened on which day. I ended up doing this for the Squid log: perl -nale 'print scalar localtime @F[0], substr($_,14)' <access.log Thanks to Sean W. for the perl pointer and everyone who contributed!

Government of Canada getting into OpenSource and collaborative development
by John Lange 07 Dec '04

07 Dec '04

When I read this posting on canopener.ca mailing list I almost fell over! In brief; there is a coordinated effort between the biggest parts of the Canadian government (Treasury board, Public works, and others) to setup a "Source Forge" like repository for software "of interest to" the Government of Canada. Apparently the government already has some OpenSource projects on SourceForge and the need for a more "trusted" distribution method was at least partly responsible for them starting this project. No official announcements have been made yet and none are expected until some time in late 2005. Read the rest of the posting for more details. -----Forwarded Message----- > From: Joseph Potvin <Joseph.Potvin(a)pwgsc.gc.ca> > To: discuss(a)canopener.ca, mit(a)mitayai.org > Cc: tadelste(a)charter.net > Subject: [discuss] Re: Canadian Mirror for FreeBSD etc. [Was: "Grants"] > Date: Tue, 07 Dec 2004 12:12:45 -0500 > > Hi Dru, Mit, et.al. I've re'titled the subject line for this thread, since it's the mirroring service you're after. I have an answer for you that you might be happy to hear, with the caveat that "were not up and running quite yet". > > Please don't interpret the following as a formal announcement since we're still in the planning stages, but I am happy to share information about, and request some open feedback on, an initiative that we're working towards to help operationalize Canadian Government Official Open Source Engagement (Canada GOOSE). This spans across acquisition, use, production and distribution. > > First, the policy context: In April 2004 the CIO Branch of Treasury Board Secretariat (TBS) requested that PWGSC "develop, manage and operate a GoC software pooling and distribution service". http://www.cio-dpi.gc.ca/fap-paf/oss-ll/oss-ll/page17_e.asp The Policy on Alternative Service Delivery (ASD) http://www.tbs-sct.gc.ca/asd-dmps/soa_e.asp#pa encourages partnerships and collaborative arrangements that bring together organizations from across government, between levels of government, or across sectors through partnerships and collaborative arrangements (e.g., single windows, co-locations, or clustering of services) where such arrangements can result in innovative, cost-effective and efficient ways to deliver government programs and services. > > With those as a foundation, Public Works and Government Services Canada (PWGSC) is currently working with TBS and several other departments and agencies in planning a Canadian Government "shared service" similar to www.sourceforge.net, www.tigris.org or www.gnu.savannah.org. Our's is (tentatively) called the "Collaborative Software Engineering (CoSE) Worksite". We're currently piloting internally with www.gforge.org) Once CoSE Worksite is in operation, it certainly could, among other things, serve as a mirror for FreeBSD and other open source solutions produced external to the Government of Canada, in which GoC has an interest. The versions we would host might be somewhat behind the latest available, as we are thinking to run a set of reviews. I say that with some hesitation, because an efficient process needs to be defined, or our reviews will be nothing but a bottleneck. Maybe certain structured communities themselves could be certified, such as FreeBSD, which has an excellent review reputation already. Again, suggestions for establishing a "highly trusted mirror service" are welcome. Generally we think GoC needs this to provide civil servants a trusted location from which to download any software (under any license type). > > Our service more broadly would include: > > 1. Development, Maintenance & Repair Management Support Systems > > - Structured, collaborative version and configuration management; > - Structured, collaborative issues and options management; > - Structured code, architecture, intellectual asset management; > - Documentation management of technical architecture and developer/user training content (integrated with RDIMS); and, > - Unified security & access management for all project participants, inside and outside GoC. > > 2. Project Team Management and Reporting Systems > > - Collaborative project management; > - Teamware for communication and coordination; > - Structured information for reporting & auditing (financial, management, intellectual, security, quality); > - Referrals to subject matter experts, communities of practice, and service brokers. > > CoSE Worksite would be available at no charge to individual software project teams working on solutions "of interest to" the Government of Canada. This language is specifically intended to mean it is not restricted to software projects initiated and managed by Canadian Government departments and agencies. Certainly, GoC software development projects would be hosted here. But other communities may also use the CoSE Worksite for any software project that meets the CoSE Project Acceptance Criteria (still being composed). In some cases, software projects that meet the criteria may already be well supported on other repositories, and the CoSE Worksite may host a referral page. We hope to avoid the limitations that the Government Open Code Collaborative is criticized for: http://www.linuxjournal.com/article/7932 (i.e. "a Cathedral trying to say it's a Bazaar"). Hopefully ours is more like "Public" Works through Government Services Canada, in which "works" are understood as "works of joint authorship" and "collective works" as defined in the Copyright Act http://laws.justice.gc.ca/en/c-42/text.html. > > For those of you who might be suspicious of the claim of a free service, please let me explain how we are trying to position the CoSE Worksite Initiative to meet the usual Treasury Board financial management requirement of full cost recovery. We're not sure if we'll be able to do things this way yet. The main idea is that we are arranging to sell the valuable "results" or "outcomes" of greater software collaboration and re-use to a few major stakeholder clients, those organizations that use it the most, and will want a place on the CoSE Steering Committee. That's to say, CoSE "services" are not the "results". The marketable value of the strategic results that are for sale under contract to the major stakeholders, will be increased, the more the online collaborative engineering facility is used. Therefore the basic CoSE Worksite web service is being positioned as a "pure public good". Like sourceforce, tigris and gnu.savannah, all the core services will be available for free. > > What's the status? The plan was discussed yesterday at the Open Source Sub-Committee of the Interdepartmental CIO Council chaired by TBS, and also a week earlier with CIO Branch within TBS. It's getting a great reception, and there are several detailed business design matters to work out as we move forward. We plan to start simply. Our team at PWGSC is currently running www.gforge.org internally for one of our open source applications called ArchNAV (as a result we haven't been updating that app at its http://sourceforge.net/projects/archnav/ location as often). We hope to have our pilot publicly-usable CoSE Worksite server running by February or March, if the main business considerations are worked out. Then, through to next autumn, we plan to learn our way forward. We should be able to advance from "pilot" to "official" by the end of 2005, running on an environment selected via a competition, which may or may not be gforge. > > All that to say: It would be great to host FreeBSD early during our pilot stage, so you'll be hearing back from me as soon as we can do something about it. > > Questions or suggestions about the CoSE Worksite Initiative are welcome. > > Joseph (José) Potvin > Management Team Member, Enterprise Architecture, Standards and Security Unit > Standards, Engineering and Project Management Sector > Information Technology Services Branch (ITSB) > Public Works and Government Services Canada (PWGSC) > Government of Canada > 11 Rue Laurier, Place du Portage, Phase III, 4th Floor (4A1) > Gatineau (Hull), Quebec K1A 0S5 > (819) 956-8617 Voice > (819) 956-8621 Fax > joseph.potvin(a)pwgsc.gc.ca > > ---------------------------------------- > > Date: Sun, 5 Dec 2004 21:29:20 -0500 (EST) > From: Dru <dlavigne6(a)sympatico.ca> > Subject: [discuss] Grants (fwd) > To: discuss(a)canopener.ca > Message-ID: <20041205212822.F586(a)dru.domain.org> > Content-Type: text/plain; charset="utf-8" > > > Anyone have any suggestions for this fellow? > > Dru > > ---------- Forwarded message ---------- > Date: Sun, 05 Dec 2004 21:12:44 -0500 > From: Mit Rowe <mit(a)mitayai.org> > To: advocacy(a)freebsd.org > Subject: Grants > > Hi, folks! > > I'm Mit, and i've been your ca.FreeBSD.Org hostmaster for many years.

According to the date(1) man page under Red Hat Linux (any version): %s seconds since 00:00:00, Jan 1, 1970 (a GNU extension) So, as long as you have the GNU "date" command, "date +%s" ought to do what you want there. > According to Sean A.

It's not a one-liner, like the above, but it does simple argument handling, calling the perl ctime() function for each numeric argument (or for the current time in the case of no arguments). It also accepts hex strings in addition to decimal numbers as arguements, and converts them as required. The following shows the (slight) difference in output format between the GNU date command and the perl ctime script, and also shows that `date +%s` does provide a compatible numeric date format... % date ; ctime `date +%s` Tue Dec 7 11:35:08 CST 2004 Tue Dec 7 11:35:08 2004 % -- Gilbert E.
