Powerline networking

2008-09-26 Thread Jonathan Peterson
I confess that I sort of forgot about the whole 'network over power 
cables' thing until I needed network access in series of buildings with 
metre thick granite walls. And concrete ceilings.

Does anyone know if powerline adaptors (things that turn your socket ring 
into something like a LAN) just work or require multiple faffing 
sessions? The actual requirement is to network the various converted 
outbuildings of an old farm. My guess is that these things turn the copper 
cables into a kind of giant unswitched 10-base-2 type network. My hunch is 
that the network is shared across every building on the same loop from the 
nearest transformer - I don't see how the signal would get through a 
transformer, and I don't see why anything else would stop it. This is 
fine, as the devices appear to have some kind of security layer that 
prevents neighbours reading your network traffic.

Has anyone used this stuff?

Just work. I've used the 85Mbps and 200MBps products from Devolo[0] in a
number of properties and have never had any problems with them. Devolo
provides Linux tools for configuration (if required), while other
manufacturers tend to just do Windows  MacOS.

I use it to get to the basement, where the wifi doesn't reach. It just works.

You just have to make sure that you plug the adaptor straight into the socket, 
or in a plain extension cord. I found that any kind of power surge protection 
will break the transmission.


The model I have seems to allow some kind of password protection for your 
network, as well as defining several networks, but I haven't tried it (the 
software is Windows-only). I used it as a plain ethernet wire.

Check first that the buildings are all on the same electrical phase:
farms can be on 3-phase instead of a single phase. These things will not
normally work across phases. And don't try to bridge phases, unless you
really understand the power engineering involved.

London.pm on Upcoming

2008-09-26 Thread Dave Cross

For probably a year or so now, I (and a couple of other people) have
been sporadically adding london.pm events to Upcoming
(http://upcoming.yahoo.com/). These Perl events usually end up looking
pretty badly attended as few people register their attendance.

In an attempt to make it a bit easier for people to find london.pm
events (and, hopefully, register their attendance) I've created a
London.pm group at http://upcoming.yahoo.com/group/12343/.

Please consider joining the group and marking on the site when you know
you'll be attending one of our events. I think this is an easy way for
us to demonstrate just how vibrant (if slightly hidden) the London Perl
community is.

Cheers,

Dave...

The other day I looked for perl on meetup.com - a group I attend
regularly use as a coordination/advertising site.
Oddly enough, there were already 17 people saying they were interested
in having a Perl meetup. I duly added myself to that list, with a
comment of Possibly those seeking a Perl meeting up should have a
look at London.pm ?

Although the wisdom of this may be questionable - I recognize at least
one name as being for a recruiter.

I used to run the London Perl Meetup group (until, obviously, they
started asking for money) and I always set the meeting dates to be the
same as london.pm. Not sure if it ever brought in any more attendees.

I didn't think I'd have to spell out the bit about let me know which
performances you can make it to, and I'll pick the one that is most
convenient and has tickets available.

perfick.

If you book them, they will come.

http://www.reghardware.co.uk/2007/11/13/solwise_pushes_powerline_sec/

I've four of these, and they mostly work a charm.

I gather it can depend a bit on how good your wiring is.  Peronally,
power-strips (four sockets, with a lead, that expands a wall socket)
really kill it.  Used directly in the wall sockets, they work really
well.

One unit didn't.  Solwise replaced it without much fuss (after I
assured them I can read and following the instructions, and had
actually tested it properly).
