If you make a new firefox profile, it will erase all your bookmarks,
history, saved passwords, etc. I don't use these much (and I don't do
this very often) so it's not a big deal for me, but your usage may vary.

It's also worth seeing really what is making is slow. Perhaps run 'top'
in a terminal and see if something is using more CPU than it should be a
lot of the time. Also, is it things other than firefox, or is it perhaps
your internet connection and so it just looks like your computer?

Robin.

Browser malware, warning from Wikimedia Foundation

Anyone struck this?

"Readers who are seeing ads on Wikipedia articles are likely to be
using a web browser that is infected with malware, the Wikimedia
Foundation has warned.
The warning points to an apparent resurgence in adware and spyware
delivered via cleverly disguised browser extensions designed to run
across multiple web browsers and operating systems.....'

Kiosk distribution.

Hi,
           I was talking with someone last night at the LUG meeting 
about a kiosk distribution.  I have a reference to one.
http://webconverger.com/
and it is Debian based.

Phil.

Meeting Wednesday night at the Duke of Wellington


I was just going to update the wiki with the new location of the Duke of 
Wellington (as was discussed at the last meeting) but someone beat me to it!

(Also, according to the calendar this meeting hasn't been confirmed yet)

I won't be there this week so you can talk about me behind my back if 
you feel the need

Sysadmin job at the medical school for someone with python skills

-------- Original Message -------- Subject: Date: From: To:

Job ad for Dunlug?

Sun, 20 May 2012 22:43:08 +0000

Nick Phillips <nick.phillips <at> otago.ac.nz>

alex <at> king.net.nz <alex <at> king.net.nz>

I seem to have dropped off the dunlug list as my old email addresses have gradually died off - I wonder if you could possibly forward this on if you think it's likely anyone would be interested :-)

We have a job ad out for a combined sysadmin/developer role. New development is predominantly python/django, but there's a variety of other stuff to support that uses PHP/Perl/Ruby, some of which (mostly Moodle I guess) also needs some development done. The job description gives a bit more detail (although I'd rather anyone interested contact me for more information), and should be findable from the ad - which is at https://otago.taleo.net/careersection/2/jobdetail.ftl?lang=en&job=1200493 Cheers, Nick -- -- Nick Phillips / +64 3 479 4195 / nick.phillips <at> otago.ac.nz # these statements are my own, not those of the University of Otago

Making deb packages

Hi all

How hard is it to make deb packages? Is there anyone interested in perhaps showing us the basics at a meeting sometime?

Thanks
Monica

Proper way to prepare and submit a patchset containing implementation of a feature to the Linux kernel project

Hi everyone,

There is a Japanese student who participated in the GSoc2011 project on the implementation of the journal support of hfsplus filesystem:

https://github.com/naota/hfsplus

The implementation is nearly there, but due to his personal circumstances, never completed.

Then his GSoC mentor Hin-Tak Leung finished the implementation last year, which targeted Linux 3.0, but he did not have time to test or maintain:

http://comments.gmane.org/gmane.linux.file-systems/56609

http://htl10.users.sourceforge.net/patchsets/hfsplus_3.0_rfc/hfsplus_standalone_20110815.tar.gz

And based on that tarball, I have fixed the code and got it compiled under the Ubuntu 12.10 Linux 3.4 kernel:

https://github.com/kcleung/hfsplus

there are only 17 lines changed from Hin-Tak's hfsplus_standalone_20110815.tar.gz

So what is the proper way to prepare a patchset containing the journal implementation for submission?

This project started with Linux 3.0, or before by Naota, and therefore the first patch would have applied in that kernel, which would be substantively different from the current Linux 3.4-rc5.

Would it be a good idea to rebase the entire patchset (contains ~25 patches) that contains the implementation of the journaling to Linux 3.4-rc5?

Or is it okay if I just diff my current fs/hfsplus/ code against Linux 3.4-rc5 and make a single patch that contains the journal implementation?

I would like to see hfsplus journaling support added into the kernel..........

Thanks!

Special unix commands for admins

http://www.brendangregg.com/specials.html

Here are a few commands from the list;

baud Run commands safely at their native baud, eg 2400, 9600. Commands are often run over high speed ssh or telnet sessions, causing Command Fault Heat State Exception (CFHSE) errors due to overbauding. This program helps prevent such faults.

ishadm Information Super Highway Administration. This checks and enables network routes to the Information Super Highway to ensure maximum Internet performance.

cdrewind Rewind CDROMs before ejection. This should be performed before every ejection, otherwise discs can remain positioned incorrectly or can leave tracks behind in the drives.

Comp Maths Talk

Thank you to those who listened to my talk last night, I hope you
enjoy your free copies of the International Journal of Offshore and
Polar Engineering (199x). More where those came from, rush to get in
first.

Three things :

______HOWTO : 5 minute Comp. Maths. with FEniCS_______

 1) Install FEniCS from the repos of your choice - ideally Ubuntu, but
I compiled it on Fedora (may also be available through yum)
http://fenicsproject.org/documentation/tutorial/misc.html#tut-app-install

 2) Try something short that you can copy-paste,
http://fenicsproject.org/documentation/dolfin/1.0.0/python/demo/pde/biharmonic/python/documentation.html#complete-code
or something a little longer but prettier:
Hyperelasticity :
http://fenicsproject.org/documentation/dolfin/1.0.0/python/demo/pde/hyperelasticity/python/documentation.html
Water flow around a corner :
http://fenicsproject.org/documentation/dolfin/1.0.0/python/demo/pde/navier-stokes/python/documentation.html

 3) Tutorial, so you can work out what you just did :
http://fenicsproject.org/documentation/tutorial/index.html

______Partial Software Recap_______
* TeXmacs (texmacs.org) - GNU TeXmacs is a free wysiwyw (what you see
is what you want) editing platform with special features for
scientists
* Inkscape (inkscape.org) - An Open Source vector graphics editor,
with capabilities similar to Illustrator, CorelDraw, or Xara X, using
the W3C standard Scalable Vector Graphics (SVG) file format

Slightly more technical bits,
* Gerris (gerris.org) - new fluids software developed by Stéphane
Popinet at NIWA with rising international uptake
* Paraview (paraview.org) - ParaView is an open-source, multi-platform
data analysis and visualization application
* Scipy (scipy.org) - family of fundamental maths, science and general
plotting Python libraries

Qichang also mentioned Scilab, a potential Matlab replacement, which I
haven't used, but looks interesting,
* Scilab (scilab.org) - free open source software for numerical
computation providing a powerful computing environment for engineering
and scientific applications

______Erratum_____
Spot the "deliberate" mistake,
* F=ma is Newton's second law, not third. Yep, fantastic slip for an
applied mathematician.

And, for anyone who is interested, the BA Flight 9 quote I mentioned :
http://en.wikipedia.org/wiki/British_Airways_Flight_9#cite_ref-Air_Disaster_2-3
They were plummeting without engines for 13 minutes.
