[SLUG] FW: Sydney to host FOSS4G in 2009
-Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Cameron Shorter Sent: Monday, 18 February 2008 6:36 AM To: OSGeo Discussions; Aust-NZ OSGeo Subject: [Aust-NZ] Sydney to host FOSS4G in 2009 http://wiki.osgeo.org/index.php/FOSS4G_2009_Press_Release_1 Sydney to host FOSS4G conference in 2009 /User Driven FOSS4G/ *Sydney (Australia) selected to host the 2009 international conference for Free Open Source Software for GeoSpatial (FOSS4G).* The Australian/New Zealand chapter of OSGeo is pleased to announce that we have been selected to host the FOSS4G 2009 international conference. The conference is planned for Sydney in November 2009, and is expected to attract the leading users and developers in the open source geospatial community. Holding this conference in the Asia-Pacific will bring enormous benefit to the region and provide the geospatial community with the opportunity to discover cutting edge spatial tools through to state of the art enterprise deployment. Jeff McKenna, chairman of the OSGeo conference board summed up Sydney's bid. The conference committee was overwhelmingly in support of Sydney's bid. Sydney's professional proposal, breadth of support from Government, Spatial and Tourist Industry, Enthusiasts and Academia demonstrated a passion that we have come to expect from OSGeo Conferences. Sydney's attractiveness and reputation as the gateway into Asia is an added bonus. Cameron Shorter, System Architect at LISAsoft explained his motivations for leading Sydney's bid were not entirely altruistic, For years I've wanted to attend FOSS4G's quality of presentations and meet attendees, but I've been held back by family commitments. So if I can't travel to FOSS4G, then why not bring it to me? The Oceania region has a reputation as being early adopters of Open Source as Steve Lime, founder of the mature Mapserver project notes, Its about time FOSS4G came to Australia. Australians have been long time supporters of Open Source, including being the first users of Mapserver outside the University of Minnesota. Oceania also stands out as the region with highest usage of Firefox, the Open Source browser[1]. *About OSGeo* The Open Source Geospatial Foundation has been created to support and build the highest-quality open source geospatial software. The foundation's goal is to encourage the use and collaborative development of community-led projects, data development and education.[2] *About OSGeo - Australia/New Zealand* The Australia/New Zealand chapter of OSGeo apply OSGeo principles locally. In particular, we focus on promotion and outreach. *About FOSS4G* FOSS4G is the international gathering of open source, geospatial tribes. The 2009 theme of User Driven reflects the migrating focus on users and integration of geospatial components into systems. The spatial industry is undergoing rapid innovations and the open source spatial community is one of the forces driving the change. From its beginnings the FOSS4G conference has been the gathering of the spatial tribes and has a reputation of being a melting pot for great ideas in the spatial industry and a catalyst for many successful geospatial products, standards and protocols. The 2007 conference was held in Victoria, BC, Canada and was a huge success[3]. 2008 conference will be held in Cape Town, South Africa[4]. FOSS4G 2009 Sydney will be the seventh formal gathering of the open source geospatial community and is expected to focus on the increasing importance of FOSS4G in the public and private enterprise.

As an international member you'd join as an associate rather than a full member, and I believe the fees are correspondingly less.

For visa information and the like you might want to start here: http://www.immi.gov.au/skilled/index.htm I have no idea whether Australia is particularly short of junior system administrators, although we are short of system administrators in general. For a company to sponsor you, they need to show evidence that they could not fill the role from within the country. Junior roles are probably easier to fill than senior roles, so the more experience you can get before you come over, the easier it will be for you and your future employer.

Re: [SLUG] perl - setting output field separator and output record separator?
Rick Welykochy wrote:
Try this:
dirs -v | perl -wnla -e 'BEGIN {$\= ; $,=:} print @F;'; echo
That works perfectly, but not quite for the reasons you explained.
$\ is Perl's Output Record Separator, and is printed at the end of every print
statement. $/ is Perl's Input Record Separator. When using -a (autosplit) we
split on spaces by default. -l enables automatic end of line processing (ie it
changes $\). Thus:
dirs -v | perl -wnla -e 'print @F;'
yields:
0/etc
1/tmp
2/home/jarich
(including the final newline).
$, is Perl's Output Field Separator as you expected. The begin block isn't
necessary so we can write:
dirs -v | perl -wnla -e '$,=:; print @F;'
to get the desired:
0:/etc
1:/tmp
2:/home/jarich
Since we're using -l anyway, we could use it to set $\ for us:
dirs -v | perl -wna -l040 -e '$,=:; print @F;'
0:/etc 1:/tmp 2:/home/jarich
or we can do it ourselves:
dirs -v | perl -wna -e '$,=:; $\= ; print @F;'

Re: [SLUG] is Perl really needed ?
Voytek Eymont wrote: sure, what I'm suggesting will not stop a serious attempt to exploit a hole, but, it should deflect such a script This is probably correct, renaming Perl may deflect scripts which rely on perl being easily found. However, patching the hole and securing your system is likely to have a greater return on investment. You mention that the script uses multiple paths to attempt to download the exploit. It may be possible that it also uses multiple execution paths: Perl, then Python, shell and maybe a few other things. Renaming all of these may not be feasible. as it was, when I realized the server was infiltrated, the 'solution' was: remove downloaders, remove perl, reboot server, problem removed; next day the problem was located, 'faulty' CMSs were deleted, and, Perl re-instated I'm not certain about your confidence here about problem removed. I understand that you haven't seen different exploits occurring, but without a full re-install it's difficult to be certain that root kits haven't been installed on your system and are now lying in wait. Most systems administrators will therefore encourage you to do a complete re-install, or restore from a known good state after any compromise. so, until the CMSs were removed, someone could've run different exploits, but it didn't happen. Depending on how much access to your machines they got, I'm not sure you can say this with confidence. Logs can be faked, important entries removed etc. lastly, now that '/tmp' is mounted as /tmp type ext3 (rw,noexec,nosuid,nodev,noatime,nodiratime) that should hopefully prevent execution of such expolits It should reduce them, but it probably won't prevent all (or even possibly most) of them. If the CMS has a directory to which it can write, then the exploit can edit that instead of /tmp/ The best solution is to wall off the CMS, or get a better CMS to start with. You may find something like TripWire a useful tool as well.

Very cool. Although probably not going to help the OP learn how to program.
Your sed program is missing it's final /. Also you're missing the double
newline between Questions. Adding this gives:

Excellent work Sonia. Here's the same program in Perl.

4: push @ARGV, 'questions.txt'; # optional

To make this work over any question file, we can remove the push on the fourth
line, and call the program with the file as an argument:
program questions.txt
The first line says to use Perl for the script and to turn on warnings. The
second line says to use the strict pragma which will help identify
typographical errors (eg $qmunber instead of $qnumber) and a few other common
mistakes.
The fourth line tells Perl that we want to add the questions.txt file to our
argument list (or we can just pass the filename in on the command line). The
sixth line tells Perl to open the files passed in on the command line and to
loop through them line by line. The seventh line splits the current line on ':'
and assigns the parts to variables. The 9th line prints it all out.
The output and calling conventions are the same.

Important variables: (1) my technical knowledge of Linux is limited though I love the philosophy of openness and (2) I am 80 years old, so at my age 'simple' also implies 'soon'. Not being pessimistic about my life span, but a race is on. The answer really is it depends. Mostly it depends on what you want to do with it. Are you learning a language to join a particular open source project? If so, then you should probably pick whatever language they're using. Likewise if you're planning to write your own code but expect to interface with existing software, it might help to pick that language too. If you're planning on working on your own, then you have more options, but there are more considerations. For example, is there an active user group for that language in your area? Sydney is pretty lucky in this regard, it has active Perl, Python and PHP user groups. It has a Ruby group, but I'm not certain of their status at this time. I suggest you join the mailing lists of all the languages you start considering. This will help you get an idea of how the communities interoperate and should also help you decide whether you feel comfortable working with them. These groups are important, as you'll need somewhere that you can ask questions. What is the best way to do X? Which is the better library for this task: X or Y? It's also important to just listen and be involved; you might learn things that aren't immediately useful now, but make your life easier later. Or just see better ways of solving common problems. People who have to teach themselves everything, every step of the way, often miss finding out about really cool short-cuts and improvements. Another big consideration is your prior experience. Learning new programming languages isn't easy. If it was, I wouldn't have such a successful business. :) If you have experience in using grep, sed and awk under Unix, then theoretically you'll have a bit of a head start in Perl. On the other hand, most of our students haven't even heard of grep, sed or awk; so experience here isn't essential. Perl, Ruby and PHP have a lot of similarities. Some of these are shared with C and thus with Javascript and Java; but these are fairly superficial. I don't know of any languages I would say are similar to Python, it's a beautiful mix of functional programming and imperative constructs, with meaningful whitespace and thus no braces (which makes it unlike all the other languages I've mentioned) - if you're starting from a clean slate as far as programming goes; this is unlikely to be significant. Regardless of your choice of programming language you may still have access to the huge repository that is CPAN, but even better you could have access to the libraries of the other languages as well. It just depends on how much effort you want to go to. For example, if you write in Perl you can access Python via Inline::Python, and PHP via PHP::Interpreter. From Python you may be able to access Perl via PyInline and so on. The biggest choosing point between the languages is what you intend to use it for. If you want to write one-liners to process lists of files, or do character substitutions; then you probably want to be using Perl. If you anticipate doing a lot of text processing (log parsing); you probably want to be using Perl. For more general purposes (medium to large scripts of any complexity), well written programs in Perl, Python, Ruby and PHP will probably both look very similar and be equally easy to maintain. The catch is of course in the phrase well written. Even with my previous paragraph in mind, it's good to pick a language which has good support for what you anticipate will be common tasks. If you expect to be doing a lot of socket programming or other low-level machine tasks; check that the language supports it without too much grief. If you're going to be doing a lot of web or report work, look at the available templating systems so you can separate layout from data generation. If you anticipate writing systems where the underlying database could change from time to time; look for a language which provides one API regardless of the database used. A final consideration is learning support. There are a huge number of very good books (and a huge number of very bad books) for each of these languages. There are also web based tutorials (of varying quality). If you're happy to self-learn then there's no issue. If you are considering getting training, your options are somewhat limited; I haven't heard of any general enrollment Python or PHP courses going on for some time now. (If you know any different please tell me.) All the best, Jacinta PS: All things equal, if you want an actual recommendation that doesn't take in to account your personal needs and requirements; I'd be happy to recommend Perl.

[SLUG] TV cloning in Ubuntu Dapper
G'day everyone, Can anyone point to a good howto for how I might clone my display to my TV through Ubuntu Dapper? I've got an ATI Mobility Radeon 9600. I've installed the ati drivers via easyubuntu and appear to have up to date versions of the linux-restricted-modules installed. I'm running gnome. I'm using the default (possibly auto-updated) version of xorg and have the xorg-driver-fglrx installed. I installed atitvout and it happily told me that it could see both my laptop display and my TV (through composite) but I couldn't get it to do anything else for me. I've attempted to follow the following HOWTOs with no significant success: * http://ubuntuforums.org/showthread.php?t=221174 The xinerama didn't seem to make any difference The ati howto made the TV flash but that's about it. * http://ubuntuforums.org/showthread.php?t=23628 Resulted in my login screen showing half off screen, no effect on the tv Also the xorg.conf suggested by Klin'Targ (no result) * http://www.ubuntuforums.org/showthread.php?t=141031 It's not a HOWTO, but I tried the ideas there, nothing useful I read the xorg.conf logs and it said that dual head displays were broken and I should use MergedFB. I don't have much of an idea of what that is, but I searched and found this: http://mg.pov.lt/xorg.conf Unfortunately even after using that as a template, all I've achieved is a lower resolution on my primary display. I've played with aticonfig: sudo aticonfig --initial --tvf=PAL-B --dtop=clone sudo aticonfig --dtop=horizontal which both worked in that I my display was mirrored in the TV but the framerate was abysmal. Attempting to play a DVD resulted in me seeing two or three seconds of movie then skipping forward by about the same amount repeating. Xine eventually complained that the framerate was too low and suggested I improved my hardware. Somewhere along the way something suggested that I installed GATOS, but the GATOS page suggests that it's already incorporated into my version of xorg. I've got a mini-HOWTO for patching GATOS to allow TV out, so that's the next step, but I thought I'd ask here just in case there's an easier way. Any suggestions?

Re: [SLUG] Graphics card problem with Ubuntu
G'day Ashley, Have a look in your xorg.conf ( /etc/X11/xorg.conf ) to see what driver your machine is using for your card. You'll need to skip down until you see a section starting with: Section Device If it's not using the ati driver: Driver ati then try changing that and see if that improves matters. If that doesn't help, then try installing xorg-driver-fglrx and changing the Driver part to: Driver fglrx A good test to see whether you're getting any difference is to run glxgears. $ glxgears They should run smoothly and at a reasonable speed.

Re: [SLUG] Contracting stuff: wrap it into a company or PAYE through agency?
Dazza has raised some good points, but also a few on which my experience
differs. Be aware that I'm based in Victoria, so it's possible that the laws
are sufficiently different between these two states to account for the
difference.
DaZZa wrote:
Maintaining a pty ltd {I.E. acn} company is expensive. You're up for a
minimum of around $2000 a year in accountant fees, fees maintain the
company name, annual returns etc. You don't HAVE to do it this way -
but a lot fo contracting agencies still insist on it.
I don't deal with contracting agencies, but there's no way that Perl Training
Australia pays that much in accountant fees, company name and annual returns.
We pay ASIC their yearly fee (about $216 if I remember correctly) and whoever
manages business names their fee every 2 or 3 years (about $50).
We do our own tax returns (they're easier to do than the personal returns once
you've read through the handbook a few times) and our own BAS. We tried the
accountant thing, but found we wanted to be more in control of our business, and
they weren't earning their money.
If you choose to run as a company I do suggest getting an accountant to set up
the business for you though. It'll probably cost you $2500, and they'll quote
you $2000 a year for the above stuff; but be aware that if you're happy to keep
accurate financial records (record your receipts etc) then you should be able to
do everything else yourself.
For what it's worth we probably spend about 3 hours a month (maximum) entering
invoices and receipts into our accounting package, about 2 minutes a quarter
doing our BAS and maybe 1 hour a year doing the tax return.
You've also got to consider that you have to run your own
superannuation if you decide to go down the company route - and you do
NOT want to fall behind or neglect it - APRA/Tax are ruthless about
chasing super input - more so than chasing tax.
At least in Victoria this isn't quite so. We use the super funds that our
employees were already signed up with, and just deposit the money every quarter.
If you're keeping good records of the salaries paid out then it's not too hard
to make sure that the super goes out when it needs to. Running your own super
fund (if you have to/choose to go down that route definitely requires an
accountant however.
The best advice I can give is find a damn good accountant - because
you're going to need one.
I agree with this entirely. Whether you use the services of an accountant for
all of your business needs, or whether you do some things yourself; you should
definitely be friends with an accountant so that you can get them to sanity
check anything if you're concerned. They're also really good at helping you
decide if a company or trust or sole trader is the best option for you. Talk to
an accountant.
Perl Training Australia ran as a sole trader for several years and we had no
troubles whatsoever with either our consulting or training offerings. Getting a
business name isn't hard; so make sure you get one if you do go down the sole
trader route (it's easier, cheaper and easily converts into a company later).
All the best,
Jacinta

Our conference is nothing without speakers, so I encourage you all to get your proposals in as soon as possible! http://www.osdc.com.au/papers/cfp06.html For those who've never submitted a proposal before, or spoken at at conference: fear not! A proposal is just a couple of paragraphs about what you think you might like to say. If your talk's direction changes somewhat when you start writing it, that's okay! Further, we encourage you to give your talk(s) to your local user groups (for example OSDClub) before the conference. This will give you some great practice time and give us the chance to give you some feedback. If you have any friends or family members who might also want to present, please feel free to pass this invitation on. Likewise if you know of any related user groups who haven't heard from us, please invite them to participate. Our goal is to make this conference truly representative of Australia's amazing Open Source development community! We look forward to seeing your paper submission.

Re: [SLUG] Greylisting on Postfix
Howard Lowndes wrote: Would anyone like to share their views on any of these solutions, or on greylisting itself. We implemented grey listing about 2 years ago. As I get most of our contact@ mail and since that address is all over the web, you can probably guess what a difference this made. I went from about 300 SPAMs every day (mostly caught by Spam assassin and my mail reader) to around 20. At the beginning, the grey listing was a bit of a pest; some mailers *don't* resend, even for legitimate mail. For example, someone I knew had a dodo.net.au email address. I consistently didn't get her emails, and didn't white-list her because she didn't tell me of the problem. She's since set up her own mail server, so that solves that. This is a problem for businesses though. I can't say whether we've lost bookings or business due to people trying to send us email and us not receiving it. I can hope that such people would call us, but they may not. If most of your new contacts are made from people emailing you; then grey listing could lose you some of those people. On the other hand, I can say that grey listing has saved me hours of looking over my spam folder, to fish out the occasional false-positive. I've been able to use this information to write more courses, do more advertising and even relax a little more. Of course, once we got our SPAM down I got subscribed to a mailing list which I had to be on, and which acted as an open relay... but that was another story.

Re: OSDC (Re: [SLUG] Snakes and Rubies?)
As the main person who organises and runs the Open Source Developers' Club in Melbourne, I'm very happy to lend you my full support in getting something like this off the ground. It may even be possible to provide hosting under the http://www.osdc.com.au/ domain if that would be of interest ( I don't run the server though, so we'd have to check first ). OSDClub meetings run every two months in Melbourne, being hosted alternately by Melbourne PHP Users Group and Melbourne Perl Mongers instead of their regular monthly meeting (this means that each group is only inconvenienced 3 times each year). We invite attendance from LUV and LUV's programmer SIG, from the Perl, PHP and Python mailing lists, and also from from related parties such as Melbourne LinuxChix, SAGE-Vic the MySQL meetup, OSIA and past OSD-Conference attendees. Of course, we also invite attendees to bring along others too. We've had no shortage of talks to suit such a wide set of interests. You can see our previous topics at: http://www.osdc.com.au/osdclub/ Some of you have probably even seen some of these presented in Sydney. Of course it helps to know that we always have a location in which to hold such meetings, and that may be your biggest challenge. A few months ago Stennie, from Sydney Perl Mongers, collected a list of various technology user groups in Sydney. This list can be found here: http://perl.net.au/wiki/Sydney If any that you know about are missing, please feel free to add them. I hope that this list will be of help when you start inviting people to your first meeting. In fact, you may even find that one or more of these groups are willing to provide hosting for the meeting in the same way that we do in Melbourne.

[SLUG] website and mailing list issues
G'day everyone, I'm really glad to see that SLUG is up and running again. Around about the 11th of January the SLUG mailing list and website went off line for a few days before returning. It appears to have happened again and only now recovered. Is this a hosting issue? Machine failure? Some failure somewhere between me and there? I've heard on the grapevine that the issue was related to servers dying, home ADSL links and general relocation, but I was wondering whether more information was available. In particular whether everything is better now, or whether more downtime is expected in the near future. All the best, J -- (`-''-/).___..--''`-._ | Jacinta Richardson | `6_ 6 ) `-.

G'day Erik,
I'm struggling to imagine any cases this would be useful excepting do-while
loops (which exist anyway). I'm also not entirely convinced the loss of
readability (if the first hunk of code was really big, I wouldn't know to look
for a butfirst block and might therefore misunderstand the code) would make it
practical.
Can you give some pared down examples of what kinds of things you'd put in each
block and in particular why you wouldn't just do the butfirst stuff before the
first block?
All the best,
Jainta

Re: [SLUG] gzip from perl script
G'day Voytek,
In a spirit of defensive programming, I have an important question for you.
What happens if the mysqldump fails? Perhaps the database goes offline part way
through, perhaps the disk fills up... since you've just deleted your old backup,
what are you going to do?
I suggest the following changes to your code:
* Take the backup first
* Check that it didn't fail
* Then do compression
* Check that it didn't fail (find out the possible failure modes,
can it corrupt your file? What happens if all the disk space vanishes
half way through?
* Then, when you're fairly certain that things will be okay, delete the
old version.
while( my ($ignored, $database) = $sth-fetchrow() ) {
print $database\n;
# Make the backup
system(mysqldump --opt $database -u $DB_User --password=$DB_Password .
$backuppath/$database-$year$month$day.sql);
# Handle any errors
if($?) {
# something went wrong... try to guess what.
die some error as appropriate;
}
# Do the compression
system(gzip, $backuppath/$database-$year$month$day.sql);
# Handle any errors
if($?) {
# something went wrong... try to guess what.
die some error as appropriate;
}
# Now that you're fairly certain that the new backup has worked...
unless( unlink($backuppath/$database-$oldyear$oldmonth$oldday.sql.gz);
# something went wrong... try to guess what.
# This could just be that the file doesn't exist.
die if you think it's appropriate;
}
}
It might also be worth using chdir to change into $backuppath so that you don't
need to keep prepending that:
chdir $backuppath or die Failed to chdir to $backuppath $!;
You probably also want to wonder why you're pulling out a column from the
database and then ignoring it.
Whether or not it's better to use system or a module to do your compression
depends on a few things, like how easy it is to get modules installed, how easy
it is to use the module you select. If you do use a module you're more likely
to have intuitive error handling rather than having to check one of Perl's very
super extra special variables.
All the best,
Jacinta

My apologies. Although I do find that it's usually better to to assume that

Ah. Remove the trailing ; and replace with a ) {

}

my $sth = Query $dbh SELECT * FROM db or die $Mysql::db_errstr;
You probably don't need to to select *. But it doesn't hurt.
while( my ($ignored, $database) = $sth-fetchrow() ) {
print $database\n;
# Make the backup
system(mysqldump --opt $database -u $DB_User --password=$DB_Password .
$backuppath/$database-$year$month$day.sql);
# Handle any errors
if($?) {
# something went wrong... try to guess what.
die some error as appropriate;
}
You might want to make the above error somewhat more useful. Perhaps:
die Mysqldump failed for some reason.;
just so that you know... I've reindented. Hopefully you just lost the
indentation in your cut and paste.
# Do the compression
system(gzip, $backuppath/$database-$year$month$day.sql);
# Handle any errors
if($?) {
# something went wrong... try to guess what.
die some error as appropriate;
}
You probably want to change this error message as well.
die Failed to gzip file.;
# Now that you're fairly certain that the new backup has worked...
unless( unlink($backuppath/$database-$oldyear$oldmonth$oldday.sql.gz);
This should be:
unless( unlink($backuppath/$database-$oldyear$oldmonth$oldday.sql.gz)) {
# something went wrong... try to guess what.
# This could just be that the file doesn't exist.
die if you think it's appropriate;
}
On further thought you proably want to change this die to the following:
warn Failed to remove $database-$oldyear$oldmonth$oldday.sql.gz: $!;
as failing to delete might not be important enough to stop doing all the
backups.
All the best,
Jacinta

Re: [SLUG] Presentation Mind Control - 21st September 2005
QuantumG wrote: Ok, I'll bite. WTF. If you have something worthwhile to say, geeks will listen to you. We don't need this motivational speaking crap. Or is this about making presentations to the mindless masses? In this case you're a perfect example of where better communication would help. You're asking a question about the need for this talk, but you'd normally hit my not worth responding to filter. The focus of this talk is about conference, user group and other similar presentations. Most of us have been to presentations which cover very interesting topics but do so in such a way that it's a struggle to stay awake and pay attention. It's very easy to create a bad presentation and it's even easier to take a reasonable presentation and present it poorly. Jiggling the mouse pointer over the slide detracts from your message as we are instinctively drawn to watch movement. Shaking coins or keys in your pocket is annoying. Speaking in a monotone or just repeating the words on your slides is a great way to bore people. When you're presenting to a group, you want them to stay awake, pay attention and hopefully retain some of the information you give them. This talk isn't motivational speaking crap - it won't tell you how to motivate people, or even cover the tips I've suggested above. There are too many better resources for that kind of thing. It isn't about making presentations to the masses either, these tips should help with both technical and non-technical talks. It's about making *your* presentation stand out in the minds of your audience as the best that was presented. It's about keeping your audience awake and interested (even if you don't have much to say). It's about making your audience remember at least some of the content of your talk. And above all that it's entertainment. If you're unlikely to ever present at a conference, user group or work meeting then the content of this talk isn't aimed at you. Hopefully you'll still find the talk amusing. All the best, Jacinta -- (`-''-/).___..--''`-._ | Jacinta Richardson | `6_ 6 ) `-.

Presenting is a rewarding, and often prestigious activity, but some speakers seem to do it better than others. Paul Fenwick shares his experiences of almost a decade of teaching and public speaking. Discover how to keep your audience's attention, how to improve your presentation techniques, and how to use mind control to get others to do your bidding. Details === When: 6:30pm, 21st September 2005 Where: James Squires Brewhouse 2 The Promenade, King St Wharf Sydney Fee: $0.00 This event is hosted by the Sydney Perl Mongers. Also presenting will be Andrew Savige discussion Damian Conway's newest book: Perl Best Practices. Everyone is welcome.

Re: [SLUG] How do you start a LUG?
that meetings go ahead. Implore all of your members to think about what they might be able to contribute next time. Try to line up speakers at least 2 weeks in advance. At the start, expect that many of the talks will be done by yourself and maybe 2 other eager people. Keep inviting talents from afar to drop on by and give talks as well. Keep encouraging your members to give talks. Make sure that every meeting has a socialisation period, whether it be at the pub/local restaurant afterwards, or beforehand while everyone else arrives, or both. When you hear someone talking passionately about some interesting (technical) topic, ask them whether they'd give a talk on that. This can work quite well. If you can't have monthly meetings, keep having regularish social events. This helps keep people connected and makes it easier for new people to join in and feel welcome (as long as your social events are inclusive). Only plan big events such as install fests when you know that you've got: * a reliable location * 3-5 reliable members who'll help you I hope that some of this helps.

[SLUG] Last Chance to speak at OSDC
G'day everyone, Put your OSDC proposal in TODAY at: http://osdc2005.cgpublisher.com/cfp.html I'm sorry if you're already sick of the idea but for those who *intend* to submit a paper proposal ... eventually please be aware that TODAY is the last day proposals are being accepted. Are you a developer? If so, then you should seriously consider proposing a talk. What would you talk about? Well, how about that really cool library/module/project that you used recently which saved your hours? How about the project you're working on now? Does your work involve a lot of text processing -- What has that taught you? Do you use your language to develop cool things like cochlear implants or monitor heart rates or predict earthquakes? Do you write documentation for an open-source project? Do you want to tell us about it? About the project, about the documenting, soft skills, hard skills, propose a talk. Are you kind of good at using an open-source tool? Could you stand up and introduce it to the rest of us? Those who already know everything about it won't be there at your talk to belittle you, they'll be at another talk. You'll have an audience of people who want to know about your favourite toy. Is there something you'd like to learn about? Like how to do profiling, or how to use a particular tool? Perhaps proposing a paper and getting it accepted will be a good motivational tool for learning. Do you know things about soft-skills that you feel your peers could learn from such as how to network more effectively, or present at conferences, or write a paper or run a users' group? Propose a talk, soft skills are important too. This conference is being run to foster and grow the open source community. As far as I can tell, this warmly includes you. Please think hard about whether you can contribute something. It's a great opportunity for you to get your name in lights, have fun and be recognised. The conference was lots of fun last year and I'm anticipating it being even better this year. If you can't propose a talk or if it doesn't get accepted I hope you'll come along anyway. I estimate (pure guess work, I'm not on the committee) that the entrance cost will be about $300. Speakers get in for free.

[SLUG] Perl Training Australia - Welcome to Perl Courses
[This email is being sent with the blessings of the SLUG committee] G'day folks, Perl Training Australia is about to run some public courses, and since we're telling everyone else about these, I thought I should let you all know as well. We're offering an additional[1] discount to those people who mention SLUG when making their booking. This discount saves $50 per person on our Introduction to Perl course and $30 per person on our Intermediate course. If you book and pay before the early bird discount dates (see below) you will get a further discount per person. [1] (We're making this offer to a few other user groups as well. This additional discount is applicable once only, so mentioning SLUG and Perl Mongers and the others will still only give you it once. I'm really sorry if you receive this email too many times because you're associated with all of the above groups.) Bookings can be made at http://www.perltraining.com.au/bookings.html Perl Training Australia - Welcome to Perl Courses Perl Training Australia will be running public courses in Sydney on the following dates: Introduction to Perl- Thursday 27 - Friday 28 November 2003 Intermediate Perl - Friday 5th December 2003 Courses start at 9:00am and finish at 5:00pm.

Each course participant will receive the following on the day: * Bound course notes * Floppy disk of exercises and answers for later reference * Certificate of course completion. Course costs are $1100 per person for the Introduction to Perl course and $660 per person for the Intermediate Perl course. A early bird discount of $100 per person for the Introduction to Perl course and $60 per person for the Intermediate course applies if payment is received on or before the following dates: - Introduction to Perl - Friday 31st October. - Intermediate Perl- Friday 7th October.
