I'm trying to cut down on the number of computers in my house. Here's
the first one I'm offering free to anyone who wants it:
Compaq Evo N410c laptop with docking bay and a D-Link DWL-G630 PC-card
WiFi adapter
1.2GHz Pentium III-M, 1GB RAM, 63GB HDD, 1024x768 LCD with ATI Radeon
Mobility M6 LY chipset
Ports: VGA, audio, 2xUSB, IRDA, internal modem, Ethernet, PC-card slot,
serial, parallel and composite video out (!)
The docking bay has stereo speakers, 2x drive bays with a DVD drive and
a 3.5" floppy drive and the following ports: VGA, audio, 2xUSB,
Ethernet, PS/2 keyboard and mouse, serial and parallel.
I can bring it to the LUV meeting on Tuesday night, or you can pick it
up from my office in North Richmond during office hours next week.
Cheers,
Andrew

Machine Type: x86_64-pc-linux-gnu
Bash Version: 4.3
Patch Level: 42
Release Status: release
Description:
The return code from ((i++)) operation is different when i has an
initial value of 0.
This problem was discovered when running run a bash script with "set
-ue" and having "((i++))" as the last command in a loop.
Repeat-By:
The following script will quit with an error after the first iteration
due to the return code errantly being 1.
#!/bin/bash
set -eu
i=0
for a in a b c
do
echo "${a}"
((i++))
done
NB: If i starts as 1, the script works as expected.
Also, using ((i+=1)) works fine, but I prefer the ((i++)) format.
Proof outside a loop:
$ c=0;((c++));echo $?
1
$ c=1;((c++));echo $?
0
Only the above was reported, but this also yeilds more proof:
$ for c in {-3..3};do ((c++));echo $? "${c}";done
0 -2
0 -1
0 0
1 1
0 2
0 3
0 4

Is there a smaller version of pavucontrol that can access all the mixers
and give a quick visual indication of current volume levels, but still fit
on the screen when you have more than 5 or 6 audio applications open at
once?

Hello All,
Having a Telstra supplied Netgear Mobile modem, nominally a Telstra4GA
device, I am not happy with the way that Network Manager connects, or
fails, silently.
What software and procedures do you use to connect to Wi-Fi networks?
I am looking for something I can largely script, but also adapt to
coping with connecting to other devices elsewhere now and then. I am
also wanting something a little more informative and verbose, I may
not initially understand all the returned information, but I can work
on that.
Regards,
Mark Trickett
Hello,
What is the easiest way of monitor SNMP data from a small number of VMs,
servers, routers, switches and UPS?
Previously I used zenoss for this. It is good in that I can tell it to
monitor a switch, and I automatically get statistics recorded for every
port on the switch (without having to configure each port manually).
On the downside zenoss seems to be bulky and complicated at times. Or at
least my legacy version (3.2.1-0) - I doubt this has changed although I
might be mistaken.
However I noticed that I am on a legacy version, and the latest version
only seems to support RHEL/Centos based systems (my current install is
on Debian). So considering that I might need to do a complete reinstall
anyway, I thought I might us well check to seem what other options there
are.

Thanks.

Hi All,
An interesting resource, there are other policies and if you go up the
chain, there are other github projects too.
This is from Linux Foundation (fwiw), enjoy!

Hi,
The laptop fell apart, I've been told that it was common with that model...
Anyway, the laptop has been disposed of, but I kept the battery just in
case someone had a use for it.
I can't really vouch for the health of the battery because it hasn't
been used for a long time now.
Other details:
+7.2V 8700mAH 62Wh
Let me know off list if you like.

Given that the third Saturday this month is actually Easter Saturday
when many members will not be able to attend, the committee is
considering rescheduling the beginners meeting for the following
Saturday, 22 April. If this is a problem for anyone, please let us know!
Once again, please do suggest any topics you'd like us to cover.
Thanks,
Andrew

Edited excerpt from the auto-generated transcript
"it turns out the instruction set and the core of the CPU is not very
important
and and it's one of those big differentiating factors that people kind
of fixate on but it really doesn't matter very much in the end.
What matters is all the infrastructure around that instruction set
and an x86 right now has all that infrastructure and it has it at a lot of
different levels. ...
I tend to look for is making if you want to make big progress in a specific
area you need to figure out how to make lots of people care about that
specific area and and that's the problem with small devices right now is
it's really hard to find lots of people to care when most of the
small devices you can buy tend to be very locked down for example and and
I'd
love to say that there's millions and millions of IOT devices that there
should be tons of people caring about them but if all these IOT devices are
actually hard to play with the only people who end up caring about these are
inside companies and it's really hard to get a personal interest in
small hardware when none of the small hardware really tends to encourage
that kind of loving"
