Further quizzing revealed that you can set it to record when those files were opened, saved, closed, and when and where any saved and backup copies were stored.

[SLUG] WordPress sessions [Was: WordPress, PHP]
quote who=justin randell that really got me curious, so i had a poke around the 2.9.2 code base. jeff, i'm wondering what led to a decision to reimplement php session handling in custom code? seems the code that leads to pulling the $user from a permanent store via an encrypted cookie value is exactly what sessions are for? was it a desire to use a non-file based store and an aversion to using custom session handlers? was it a desire to control the strength of the cookie hash? Most likely both... on top of that, consider WordPress's relative age, ease of installation / configuration (particularly on shared hosting platforms where the user has no control over the system), and desire to support older system components. An interesting question though, for which I'm sure there's more historical background (and rationale for not switching to PHP session handling in later versions)...

[SLUG] bash tips (tr, cut, loops, fields, records) Was: shell scripting help
quote who=Daniel Bush
Writing a little utility to help me on something but having trouble.
Why does f stay blank?
Answer (which I think was mentioned in earlier responses): The parent shell
doesn't have access to the subshell's scope. The usual way of doing this is
to provide output from the loop into a variable, like this:
PANTS=$(echo foo|bar | while ... echo -n $F ...)
Solution: Depends on the actual task rather than the example. :-)
d...@lin4:test$ echo foo|bar | awk 'BEGIN{RS=|}{ print $1 }' | while
read s; do echo $s; f=$s; done; echo '$f'
foo
bar
''
A couple of thoughts (note that I always use caps for variables for
clarity)...
echo foo|bar | tr '|' '\n' | while read S
tr is awesome.
Then, assuming the number of fields in each record is consistent (and in a
real example you're probably in a loop of some kind over the records before
you're in a loop over the fields):
echo foo|bar | tr '|' '\n' | while read S; do
echo $S # or otherwise do processing with each field
done
F=$(echo foo|bar | cut -d'|' -f2)
cut is awesome.
Another way of looking at records/fields, if that is the problem you're
actually facing (beyond the simplified example):
while read RECORD; do
echo $RECORD | tr '|' ' ' | while read FIRSTNAME LASTNAME; do
echo Welcome, Mr. $LASTNAME,
done
done records.txt
(Instead of mucking around with tr to muck about with the record separator,
you could just use the bash IFS variable, but there are some little catches
with that, which are not worth going into for now.)

Re: [SLUG] 40 Years of Unix
quote who=Marghanita da Cruz I am trying to figure out where Bash etc fits into Linux. Does Gnome/KDE run in a Bash shell? They are forked from a shell, mostly because startup scripts are all shell scripts. GDM (which in turn starts X) is spawned from a shell script. On pretty much every Linux distro, when you log in or run a terminal, you are typing commands into a bash shell (which you can swap for something else if you're that way inclined, but most folks use bash). The word shell sometimes refers to any kind of parent or launcher process, so that's where you might hear people refer to GNOME, KDE, progman.exe (on Windows) or dosshell.exe (aptly named) as shells. - Jeff -- linux.conf.au 2010: Wellington, NZhttp://www.lca2010.org.nz/ You gotta know when to hold 'em, know when to fold 'em, know when to walk away, and know when to run. - Kenny Rogers, The Gambler -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

In this case, given your requirements (CGI + SSL), Apache is probably the easiest choice (particularly the Debian/Ubuntu packaging, which is nicely set up and very helpful). I've been playing with nginx in front of Apache recently, and aside from the minor problem of nginx not doing keepalive to backends, it has been great. Easy setup, really easy SSL, and for CGI I generally pass back to Apache or boa (which is a lovely little server, particularly for embedded use cases -- but it won't do SSL for you). nginx 0.7.x (which I track in my PPA) does front-end caching too, which is very handy.

Re: [SLUG] HD ( 1920 x 1080) monitor and Linux - advice pls.
quote who=bill I have decided to upgrade to a 24 inch monitor and after looking aroiund I se that Oz has finally caught up with overseas and that HD 1080 monitors are now available. Most wide screen computer monitors have a pixel ratio of 16:10, unlike TVs which are 16:9... thus, the usual HD resolution for computer monitors is 1920x1200, not 1920x1080. HD monitors have been available in Australia for ages, so I'm wondering if you mean something else. My problem is that such a monitor can not be run with 3 of my PCs all of which have NVidea cards which dont have high enough or the default 1920 x 1080 res available. My newest PC which has an Intel mini-itx 1.6 Atom CPU mobo only has 1 slot and that is PCI ( not PCI-E) and the onboard Intel CPU has a max res of 1600 x 1200.

Re: [SLUG] bugzilla setup
quote who=Ken Foskey I am trying to get bugzilla3 working on my ubuntu server and it looks awful. Is there a CSS that needs to be installed to make it look nice? GNOME has one of the prettiest and most useful Bugzilla setups around; you might want to check out what they've done to it. Pretty sure it's still on Bugzilla 2.x though. Is there a better very simple web based bug tracking that I should be using? Well, pretty much anything else is simpler and easier than Bugzilla. It was really designed for very big projects with well-understood processes (such as Mozilla, where it was born, and GNOME, where it continues to thrive).

Re: [SLUG] upgrading Ubuntu with CDs to save bandwidth?
quote who=Sonia Hamilton Last night I was trying to upgrade some Ubuntu machines using the Ubuntu CDs (rather than downloading all the packages), in order to save bandwidth.

Re: [SLUG] network manager over writes resolv.conf
quote who=david Just upgraded to Ubuntu 8.10 (from 8.04) and now I'm losing my search domain on reboot. I'm using a static address. If I edit resolv.conf everything is good until I reboot, then resolv.conf is re-created without the search domain. Where should the search domain be stored? I thought it was in /etc/network/interfaces but apparently not according to man interfaces. Previously there was a line: dns-search kenpro.com.au I was expecting something like .gconf/system/networking but that doesn't exist and I can't find anything similar. Never edit the GConf database directly [1], use the tools. In this case, you want the Network Manager connections editor which you can find by context clicking on the Network Manager panel icon (then Edit Connections...) or System Preferences Network Configuration. Choose the wired or wireless connection you want to set a search domain for, and click Edit. To set the search domain you want the IPv4 Settings tab, static addresses, etc. Sure, some people don't like Network Manager because it pulls you out of the comfy configuration files you might be used to, but it does a whole lot of stuff for you if you don't want to bother with them anymore (or never found them easy or comfy in the first place -- ie. my Mum). Also, if you set stuff up in /etc/network/interfaces, Network Manager will ignore it... at which point the resolvconf package will be a handy way to manage your resolv.conf settings via /etc/network/interfaces. :-) - Jeff [1] Not because it's impossible to do so, but because it's almost never the easiest way to achieve your goals. -- linux.conf.au 2009: Hobart, Tasmania http://marchsouth.org/ I tried to make money ass signing, but the bottom fell out of the market. - Liam Quin -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

From my original post: System/Preferences/Network Configuration GUI tool fails with the following message: Updating connection failed: nm-ifupdown-connection.c.82 - connection update not supported (read only) So now that the lovely clever gui tool doesn't work, what do I do next? go back to the old fashioned config files that I was comfortable with? I can't because they are now mysteriously over-written or silently ignored! Well, a) that's not the GUI tool I directed you to (it's no longer relevant in Ubuntu 8.10, so you should uninstall it) and b) I did mention in my mail about how you can go back to the config files and NM will very happily let you do it (by ignoring the interfaces you've configured). We are being dumbed down. I'm quite happy to have simple tools for my Mum, but surely in a perfect world the simple tools would advise us what's going on under the hood. At the moment it seems to be as secret as Windows. The tools would advise you? Like Hi David's Mum, you don't care about this, and it's more than likely to confuse the fuck out of you, but I'm now editing BLAH BLAH BLINGDEE BBZZZT WIDGET. Have a nice day! As a technical user, there are certainly methods for you to better understand what is going on underneath the covers, but there's no reason to expose that machinery to users who don't give a shit. (And it's not quite as simple as generated from ...) Due to advances driven by NM, I haven't edited /e/n/i on a desktop or laptop system for years. I switch between VPNs, wired and wifi, and most recently plugged in a 3G card... and it all just works. I happen to grok what's going on under the hood, but I don't have to care about it, so I can spend more of my synapses on stuff that actually matters.

Re: VoIP adapter configuration was /Re: [SLUG] Thunderbird send problems
quote who=elliott-brennan One last question. How do I fix the MTU setting so I don't have to reset it each time I reboot. For my desktop this is not really a problem - it's on 24/7, but I'd rather just have it sorted. You're using sudo, so I'll assume Ubuntu if that's okay [1]. Just add an mtu parameter to your /etc/network/interfaces stanza, eg. iface eth0 inet static address 192.168.10.110 netmask 255.255.255.0 gateway 192.168.10.1 mtu 1492 - Jeff [1] This only makes sense when you think about it in terms of probability. -- OSDC 2008: Sydney, Australiahttp://www.osdc.com.au/2008/ I don't know whose brain child it was, but it was quite an ugly child. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] Equivalent of Gentoo's python-updater for Debian
quote who=Michael Lake Now a colleague at work tells me that his Gentoo has a thing called python-updater that remerges python packages when upgrading python. This makes all the old packages available for an updated python. Is there such a thing for Debian? python-central (and Debian packaging guidelines for Python) does it all for you as you upgrade. Since those changes were made, and we no longer have version-specific Python library packages, I've never had to do anything manual to get a Python library to work with a particular version of Python. It just works for versions of Python that you have installed. - Jeff -- linux.conf.au 2009: Hobart, Tasmania http://marchsouth.org/ Free software never simply picks up its marbles and goes home. - Jonathan Corbet, LWN -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Re: [SLUG] composite multiple images command in imagemagick
quote who=Rick Welykochy I've always pondered where to draw the line between sys admin and programmer /analyst. Wherever you draw it, draw if very firmly. Sysadmins should not write code, Bollocks. I've yet to meet a sysadmin who does not write code. But I classify it as scripting. Yeah, that's pretty much the distinction I was assuming.

Re: [SLUG] Video card problem?

Unfortunately those log items don't reflect anything about the problem you're seeing. The gdmgreeter bit is just silly GDM bugs that should be fixed and the ALSA bit is normal (and not video-related).

Re: [SLUG] composite multiple images command in imagemagick
quote who=Rick Welykochy I've always pondered where to draw the line between sys admin and programmer /analyst. Wherever you draw it, draw if very firmly. Sysadmins should not write code, coders should not administer systems. Heinous crimes are committed when the streams are crossed! Many sys admins I work with can whip up shell scripts and are whizzes at handling utilities and such in the shell. But often they are not adept at designing software systems and implementing them. No offense, admins, but it is a different discipline. Absolutely. But the inverse is also true. :-) Which raises the question: does it require a programmer to handle and correctly execute complex command-line programs like convert, etc. as found in Imagemagick? Naw, those are pretty straightforward if you have the mind-set for them. I'd venture that ImageMagick is not exactly the most useable suite of command line tools. :-) As an aside, my brain begins weeping when I have to do something novel with iptables (another command-line monster) but I don't consider that a programming job. I get the impression many Linux admins can configure iptables in the dark without a keyboard and both hands preoccupied with beer and pizza. iptables is firewall assembly language. There are other things that provide the equivalent of portable sugary description (equivalent to C in the code ecosystem), concise object-oriented approaches (equivalent to languages such as Python), and even visual approaches (logo for firewall designers!). - Jeff -- GUADEC 2008: Istanbul, Turkey http://www.guadec.org/ GNOME, launched specifically to counter a threat to our freedom, is the free software project par excellence. - Richard Stallman -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
