I think it's the forth Saturday tomorrow? Knights Templar near Temple Meads.

I look forward to a bit of discussion on a more formal event as proposed earlier this week!

Here is my 2p's worth from our recent experiences!:

A cheap or free venue close to centre needs to be found and funded if
necessary.
One person need to co-ordinate everything.
MOST IMPORTANT, it needs to be advertised widely!

I am not sure if I will be at the KT tomorrow.

It's been suggested before, but never really got off the ground. Basically, the main issues are around organisation - someone needs to work out the dates and arrange the "speakers", and book the room. Also, you need to have a certain minimum number of people agree to turn up - at the moment, the KT meetings are convenient because it doesn't matter whether 2 or 20 people turn up. If you book a meeting room for, say, ?50, then that's not too bad between 20 people, but if only 2 turn up, it's a bit much to ask those two people to cover the room fee between them.

The KT meetings have got a bit more difficult over the years as the KT tends to be busier on Saturdays than it was. When we first started having meetings there, it was ideal because it was typically mostly deserted, so we often had the whole raised area to ourselves.

FWIW, my opinion is the same as it's ever been - if you (and/or someone else) want to organise it, go ahead. BBLUG has never had a formal organisational structure, so things get organised (or don't) when people decide to do them. If I have the time available, I might even come along :)

I also have a DLP projector + screen if it's of any use.

Hello Luggers,

As i've said before , i would love for bblug to meet anywhere else but that
horrible pub.

Bristol hackspace at bv studios could be a possible venue , see
http://bristol.hackspace.org.uk

Possibly even somewhere at the watershed or hamilton house could be found.

An option i've seen work for various groups in london is for a company that
employs one of the
members of the group is persuaded to offer the use of its office on
saturday. (mine is too small)

I would be up for attending monthly or bimonthly tech meets where
lightining talks might be given
or group hacking/installing sessions could occur. I don't have time to
organise it myself tho.

Cheers
Amias

Hi, could anyone on here be able to help me for say a couple or three
hours during this weekend here please, South West Bath, to get a New PC
up and running with an openSUSE install?

Have sort of hit a brick wall with getting this 'beast;
up and running, also am not well which doesn?t help.

PC is an Asus B85 mothrer-board with a quad core Processor, 32Gbb of
RAM, SSD boot drive and then two Server type disk drives, also a dual
monitor display....etc.

Please Email for phone for contact info

many thanks in advance
Mik

I'd like this. I'd expect there'd be a limit on how often we could do
this before running out of willing speakers with things they felt like
talking about, but that's OK. Perhaps that's the best place to start:
encourage lurking-but-willing presenters to say how many potential
presentation-minutes are out there sitting wasted, both one-offs and
regular (but wouldn't they have replied to this already?). Worry about
attendance and venues after we're sure there's something to present.

I suspect structured meetings would be more popular, based on anecdotal
evidence. Another group I go to has ~4--8 people for the social meets
but ~30 for more structured talks. The curious could probably click
around a few technical meetup.com groups to confirm or reject this,
since they expose RSVP numbers which are reasonably accurate.

meetup.com might be worth considering for marketing too, but they start
charging over something like 50 on-paper members (even if none of them
ever turn up to anything).

> I also have a DLP projector + screen if it's of any use.

That could mean we can get away with a cheaper room. Some PFI-enslaved
taxpayer-funded organisations pay per meeting and get charged
substantially more for a room with even a whiteboard, which might be
indicative of venue providers' pricing more generally.

It's not very big --- AIUI Dorkbot (the parent organisation) typically
holds its own meetings at the Watershed instead --- but it's probably
friendlier to organise with than other options.

To be able to meaningfully interact with a device via a web interface
will require a MAC layer, a TCP/IP stack, a web server and some web
application layer (you do want authentication so hostile people can't
change the parameters during use, right?). Even a minimal
implementation of this is a lot of code that you don't want to write
yourself (TCP/IP implementations have some *very* subtle security
requirements).

How much of this do you need for the other functionality of the device?
If the device is basically an embedded Linux box with some custom
hardware that streams things out over an ethernet port then, sure, add a
web interface, it will be little hassle. However if the device is
mostly analog magic with a small embedded microcontroller that takes
analog in and out then a web server is probably massive overkill and
you'd be better off with maybe a USB interface and then just documenting
it so people can write drivers.

In short, can you tell us a bit more about the device -- what I/O does
it have, how many CPUs, what types, etc.

Cheers,
- Martin

Well, you probably want to check your version of "su" can be invoked like
that. I have no idea which of the many "su" binaries your distribution
ships with, but the lowest commn denominator is to invoke as:

su -c 'command args' user

The username MUST be the last argument on hte string and the argument to
-c MUST be a single token if you want to be sure it will definitely work
with whichever su you happen to find yourself lumbered with. The example
given is not guaranteed to work, and certainly won't work on any system I

All
Certainly this is a very interesting Project that Alex has.
I'm also involved in it a bit and have have helped with some of the
hardware side of things; but unfortunately the Firmware/Software side of
it isn't my thing at all :-(

Three different frequency range 'Speakers with three Amplifiers built in
using this Loudspeaker Management System for each of my new HiFi
'Speaker boxes - all pre-set tuned specially for this application to
have everything work to it's best ability is one use for it.
More info if you are interested by Email please, as this is a Software
list after all.

So on Alex's behalf am asking again please for someone who can help with
Firmware/software in getting this very interesting project plus some
'spin-offs' moving forward please

thanks in advance

Hello Alex,

You might find more answers to this type of question on the bristol
hackspace list.

Here is their website
http://bristol.hackspace.org.uk/

FWIW i think you might be able to buy an ethernet interface that would do
most of this for you.
This would also take care of updates as well , which as martin said , will
be important.

Cheers
Amias
