Hi all,
I have a TV which has a built in USB record feature (which basically
dumps DVB-T MPEG TS in 2GB chunks). I'd like to pull the audio track
out of something I recorded. VLC happily plays the file and identifies
the video, audio and EPG info in the transport stream, but if, for
example, I run:
avconv -i ... -acodec copy audio.mp3
... I end up with about 2 seconds of silence.
It seems there's a couple of dummy streams and also that the overall
file is prefixed with what looks like null garbage. I know that if vlc
can play it, there's gotta be a way of extracting it, but must admit
that I haven't had any luck thus far.
Any ideas on recommended tools for stubborn MPEG TS demuxing?

Hello All,
I am making some efforts, in association with others, to set up a
bootable USB stick with Knoppix for the Adrienne audio desktop for a
blind user. Since they are a diabetic, and have regular finger pricking
for a blood sample for the sugar levels, setting up a braille output
device is not an option.
I am cooperating with another person by email (and snail mail, to the
US) in this endeavour. I would appreciate comments about which browsers
are better with various audio environments, and to remember that the
established system will require to be run solely by the audio, including
confirming all typed keys for input. In this regard, it may even need to
report the actual keys typed when providing the password. Yes, that is
quite insecure, but will be necessary for the targeted user to be able
to log in.

The only time I've received systems from Grays which differed from the specs
was when I bought a batch of PCs and got one with half the described RAM and
another with a defective motherboard. I moved a DIMM from the broken system
to the system that lacked RAM and reported the problem of a defective system
with missing RAM. They arranged to have the system collected and refunded my
money with no questions asked.
The only time I had a problem with Grays was when I bought some Compaq desktop
systems which have external PSUs which were shipped without the PSUs. Grays
said that the description didn't say that a PSU was included so they
considered that to be OK. The moral is that you have to make sure that any
extra bits which are necessary are included in the description.

If you want an Australian auction site with a reasonable amount of computer
gear then the options are eBay and Grays. As being more reliable than eBay
isn't a challenge that makes Grays the best option.

Hi,
I'd like to get a new desktop computer system; I'm currently using a 1.8
GHz C2D with 2 GB of memory with debian squeeze. It doesn't seem up to
the job any more; HD movies are choppy; iceweasel is sluggish.
I use my computer system for typical desktop reasons:
Gnome
Internet browsing
Evolution mail client
amarok
Watching movies
Basic image processing with gimp.
I'm thinking of getting something along the lines of:
i7 3.4 GHz
4GB DDR3
2 TB HD
Graphics card.
I'll probably stick with debian but I might try out ubuntu and linux
mint distros.
Does this sound reasonable?
Any suggestions or recommendations?
Hello,
Open Source Industry Australia, OSIA, would like to invite you to
participate in an online survey relating to the Open Source software
industry in Australia. Any one who has an interest in the Open Source
software sector is welcome to complete this survey. This includes but
is not limited to OSIA present and past Members, Open Source Software
service providers, other IT service providers, users of Open Source
software.
This survey serves 2 main purposes:
1. To provide a better understanding of the sentiments of its Members
and other Open Source practitioners in regard to OSIA's activities.
2. To provide a better understanding of the general state of the Open
Source Software sector in Australia and enable baseline data to be
established which will facilitate the evolution and progress of Open
Source software to be traced in future surveys. The available capacity
in Australia to deliver Open Source services and products, and human
resource issues are of particular interest in this survey.
This survey should take about 10 to 15 mins to complete.
To access the survey please follow the link below.
http://osia.com.au/surveys/index.php/288243?lang=en
Or visit the OSIA website (http://www.osia.com.au) and follow the link.
This survey is open until the 8 May 2013.
If you have any query or which to provide further comment about this
survey, please email: survey(a)osia.com.au.
We hope that your contribution will help OSIA better support the Open
Source Business Community in Australia.

OSIA Board
About to rebuild the network here after moving house. One issue I'm
contemplating is performance and redundancy. One part of the network
can't (easily) be reached by Cat 5/6, running cables t that part of the
house would be too messy at best. I have two ways I can bridge this gap
- Powerline Ethernet adapters, which have worked extremely well in the
past, or WiFi, using an access point in client bridge mode.
Now the powerline adapters do work extremely well, with a rated speed of
85 Mbps. I've never had an issue, except for the switchmode supply of
one laptop, which trashed the link (took a bit of detective work that
one!). The biggest weakness of these devices is that they can't be
battery backed up. If the mains goes down, so do they.
WiFi can be backed up, especially since a lot of the gear I have will
happily run off a 12V battery, and some of the systems on the far end
will be running off a battery backed DC supply. However, performance
with the WiFi solution isn't as good.
Is there a way I can (easily and cheaply) arrange to run on the
powerline devices by default and fail over to WiFi, if the power goes down?

Hey folks,
Anyone use an Android remote control solution?
Not using Android to remote control something else, but another device
to control Android? Preferably over WiFi..
I've used Airdroid and SSHDroid to do file, SMS etc. access, but
looking for something that'll provide remote GUI access. There are a
few things about that I found, but some seem to be rather old and
unmaintained, of dubious background (not many reviews etc.). One even
suggested "chmod 777" on one of the Android system areas... Uh.. NO..
How do you folks go about remote control of Android devices?

Many thanks I'll check out the URL;
I seem to have a fascination with durability.
There was an interesting program on the deserted city of Chernabyl on SBS;
it made the point that little in the modern world will last more than a
100 years.
Also amongst those materials which do last : stone obviously;
there seem to be others which are peculiarly durable for no obvious
reason;
I seem to recall mention of Chinese cement containing rice powder !
