[clug] problem with 'lame'?

I wonder if anyone can explain the problem I had. I now do not use this method (I do ffmpeg) but still
want to understand why it was failing.

I was transcoding podcasts (music programs) for many years with a simple script.
This was the way of converting everything to pcm upfront (mplayer) then encode as mp3 (lame).

This worked fine until some time ago (first short one was Aug a year ago) when it started truncating files.
This was consistent, with exactly the same truncation every time. Below is an example.

(1) Note the original length 2:05:04.0
(2) Then note how lame *starts* with a length of 1:41:21
(3) The result says 1:41:27.0
(4) Finally note that capturing the pcm shows it is not truncated.

===== test.sh
prog="my_program"
pipe="$HOME/tmp/xxx"
mknod "$pipe" p
mplayer -really-quiet -nolirc -nojoystick -vo null -vc null -ao pcm:fast:waveheader:file="$pipe"
$prog.m4a &
lame "$pipe" $prog.mp3
rm "$pipe"
=====

===== (1) play the original
$ mplayer my_program.m4a

[clug] Splitting a file using bash

I want to turn stdout into  multiple files. I have markers where I
would like this to happen.

stdout:
data
data
data
this_is_a_marker
data2
data2
data2
data2

only it's very large

I have this function which works, but is slow.
Better ideas would include:
1) re-write everything in another language eg python
2) re-write split reports in C
3) ask CLUG if anyone has a faster way of doing this using standard
bash 4.1.2 or older on a redhat enterprise/centos system.

Yeah I just asked about optimising a shell script, I already feel bad
and you don't have to point out that I should. ;-)

function split_reports()
{
    local input_file="$1"
    local first_report="$2"
    local second_report="$3"

Re: [clug] [OT] NBN migration & ISPs

I'm only running a TP-Link wireless router (n) to the NTD via internal cabling.

We're up and running now, but there were some initial glitches. A
Thiess tech installed the kit & allegedly tested the connection. I
spent some time stuffing about that evening, unable to get online -
even when directly connecting some laptops to the NTD.

iiNet's specialist fibre team were pretty useless when I called them
(ie. "is the LED green?"). Apparently they could see my system
connected, but I wasn't getting assigned an IP addr (for either the
router, or the laptops). One of the laptops randomly made a
connection, then the router managed to connect when I plugged that in.
It seems to have been working since then.

I'd still prefer to move to a better ISP :-)

[clug] [OT] NBN migration & ISPs

Hi all,

I figured I'd consult the local linux list hive mind for some NBN ISP
opinions. The existing linux list archives didn't turn up anything,
although there were some threads on whirlpool.

Given the migration was from the Transact FTTH monopoly, by default we
were signed up with iinet. Their rates are not particularly
competitive & technical support was pretty bad. eg. on a call I
mentioned using Linux, which got the stunned response "oh", followed
by instructions to type Windoof commands...

A more technically savvy ISP would be nice :-)

For those on the NBN, has anyone got any recommendations/experiences
with other ISPs?

If it helps, our 2P household are only light-moderate users: mostly
mail or web browsing, no gaming, occasional streaming of iview & Skype
calls.

cheers,

Ben

PS. if anyone is interested, I can post some details of the migration
installation. This was another area where NBN Co / iiNet were lacking
in info, resulting in more hoops to jump through.

[clug] authenticated RPC

Are there any RPC protocols out there that have
authentication/aothorisation built in? It seem to have been over looked
in every one I've looked at. I'm using python to write some middle ware
to sit between a django front end on one server and a privileged service
on another, exposing a limited set of functionality. While I'll be
locking it down to only one or two IP addresses I'd still prefer to have
the extra level of protection of authentication. Not just as a mean of
defence in depth, but also to stop other things on the front end server
from having access or to change what functionality is available
depending on the user.

Jeff.

A quick google search for "LPI training materials" showed a lot, including:
http://en.wikibooks.org/wiki/LPI_Linux_Certification

Each link shows the relevant LPI training requirement, some explanation to get 
you started, and a set of exercises that reinforce the training point(s).

You could always search or ask here if you have questions about a specific 
issue.

[clug] Anyone managed to get Epson PrintCD working in Wine?

Hi Guys,

I have spent the past 3 or 4 nights trying to get Epson PrintCD 2.2.4 
working under Wine 1.7.22 without luck. It installs fine, and the 
program does everything it should, so that's a win, but it won't see the 
CUPS printer driver. I've tried loading the Windows Printer driver 
within Wine, but I can't get past the error message "This software is 
not suitable for your system" (or similar to that).

I've hit up the Wine forums and found mixed results there, but nothing 
really helpful. I've tried a few different versions of Wine too via Play 
On Linux. I've also tried a few versions of the program as well.

Has anyone had any luck getting it to work? Those who are unfamiliar to 
the app, it's a program for design layouts for printable CDs, which you 
print out using the special feeder on the Epson Artisan 730 printer.

I have setup gLabels, which is working reasonably well, but I can't 
force a change to the printer margins, so the printing is 3mm off from 
the left and top of the disc.

I also have an issue with the print quality to the disc, even though the 
print dialogs are all set to CD, the printer seems to be using plain 
paper ink levels.

I was reading about Gutenprint tonight, but I haven't tried it at this 
stage.

Thanks in advance
