Audio tech upstart DTS takes on Wi-Fi speaker juggernaut Sonos

Dave Stevenson

Don't need a Bridge.

Sonos Bridge required? Really? I don't have one as I have ethernet run to a ZP100 or ZP80. Almost all of the products have at least one ethernet port and thereby remove the need for a bridge. The baby units (Play:1 and the like) may not have them though, but supposedly only one node needs the connection.

Then again the mesh network performs so badly at my place that I've ended up with ethernet to 4 of my 5 zones and a switch that supports spanning tree. Perhaps the updated mesh in the ZP90 and ZP120 would perform better, but upgrading costs too much for limited gain.

EE still has fastest, fattest 4G pipe in London's M25 ring

Re: Not a Ring

You beat me to it! It's one of those useless pub quiz bits of trivia.

Not just bicycles, but any vehicle that is prohibited from motorways (eg tractors).

BBC boffins ponder abstruse Ikea-style way of transmitting telly

Re: Justification

Memory says that The Matrix DVD has multi-angle stuff on the behind the scenes bit about the shooting of bullet-time or the like. Also Men In Black had a deconstruction of the tunnel scene (where they drive on the roof of the tunnel), and you could switch between the layers that were composed into the final sequence.

My memory could be failing me though, and they weren't great uses of the technology at that.

UK malls use Google in desperate stab at luring shoppers off the web

Re: Oxford vs Cambridge

Not so sure I agree with you on the Cambridge P&R. By the time you have a couple people in the car you can get almost half a day of parking at say Queen Anne or Park St car parks for the same price, and you've saved up to an hour each way (ask my other half!) on the bus.

And the Longstanton P&R is just confusing as it depends which bus operator you use as to the cost of a ticket into town, and they're not transferable between the two.

Grand Arcade - OK, enough said there!

The Hardware Hacker's Guide to Home Automation

Re: Question?

I'm looking at doing almost the same thing but via openenergymonitor.org hardware rather than RPi. OEM can monitor the power being generated by the PV, and that being consumed by the rest of the house, and (with a little extra code) turn on the immersion heater if there is sufficient surplus.

RPi will need some interfacing to be able to monitor power (unless your inverter already has Bluetooth or similar for remote monitoring). It does have onboard GPIO so that it could drive a relay directly (no USB interface required), although a Gertboard (search the RPi blog) may make life easier.

As a further trick, drive your immersion heater via a high powered dimmer circuit (triac), and you can make use of all the surplus power from your PV, even if it doesn't exceed the threshold to turn your immersion on at full power. Read the OEM forums for various discussions on that.

AdBlock Plus man disputes Mozilla add-on tests

Happy

@heyrick Re:Yup

You want to try BarTab (https://addons.mozilla.org/en-US/firefox/addon/bartab/) instead of toggling Wifi off when restarting Firefox. It stops Firefox reloading all but the active tab on restart, and then automatically loads those tabs when you select them. It's made a big difference to me.

Sonos ZonePlayer S5

Dave Stevenson
Unhappy

Half the price of a BU250 bundle...

.. but also under half the functionality. The BU250 includes a CR200 controller and two ZonePlayers (one with amplifier, one without), but an S5 and ZoneBridge for £429 is only one zone and no controller. Makes the price comparison a bit daft.

I should add that I'm a very happy Sonos user, but I'm unlikely to add one of these as an extra zone.

Aussie censors implement six degrees of separation policy

How about tinyurl.com?

So if an Australian web site wished to link to a "banned" web site, why not just create a tinyurl.com shortcut to that particular site and publish that link? Same end result for the surfer, but the website isn't publishing a direct link to "banned" content, so (potentially) no problem.

If links to links aren't permitted, then go through 2 tinyurl.com URLs (although I've never tried that to find out if it works).

I think the idea is to make themselves look foolish and waste a lot of taxpayers money - they're succeeding.

Brussels: Old-school lightbulbs to be gone by 2012

Dave Stevenson
Thumb Down

And what about those with reflector bulbs and/or dimmers?

Great, so anyone with reflector bulbs is now expected to pay over £10 per bulb, compared to about 50p. They better be incredibly efficient if I'm to save £9.50 in electricity over the life time of the bulb (I guess it may be a bit less as the bulb life is meant to be longer).

And so few of the low energy bulbs can be dimmed, so anyone with dimmers is forced to buy the more expensive versions.

Cheers Brussels - I'm off to stock up on spare bulbs.
