Listening to music over wifi?

Published December 16, 2008

Hey lazyweb! Long time, no write.

I’m wondering what setup people use to deal with the following situation. Upstairs, I have an Ubuntu 8.04 server with 71GB of MP3s. Downstairs, I have a stereo system. In between the two is a wireless network. How can I listen to the music downstairs, without simply copying the lot (or subsets thereof) onto a local disk on some appliance down there?

Currently, I’m using a VNC client on a Nokia 770 to control a JuK window on the server. This works great, believe it or not! KDE 3 can be coaxed into providing a fantastic UI for a small touchscreen. This then uses Pulseaudio to transmit the sound output using the ESD protocol over TCP to the ESD server on the N770, and the N770 plays back the sound.

Until a few months ago, this worked great. However, something (either hardware changes, network topology changes, or an upgrade to Ubuntu 8.04 on the server) has resulted in effective bitrates between the server and the N770 dropping frequently — hence the audio drops out or changes pitch, rendering it unlistenable :(

I’ve tried using UPNP servers (specifically mediatomb, ushare, and Twonkymedia), with the built-in Media Streamer app on the N770. All fail. MP3s cut off near the end, M3U playlists aren’t supported, and sometimes Media Streamer just locks up. In addition it’s pretty messy trying to get the UPNP servers to notice changes to the MP3 collection.

I’ve also tried using Squeezecenter (nee Slimserver), but the MP3 stream playback support on the N770 is pretty atrocious; there are audible decoding artifacts.

So — anyone got a suggestion? Even something involving iTunes might be helpful — as long as it can at least preserve the Linux server. I’m unlikely to host the full MP3 collection on anything else…

Recession Hits The Digital Depot

Published November 26, 2008

The Digital Depot is ‘an innovative, state-of-the-art building specifically designed to meet the needs of fast growing digital media companies […] developed as a joint initiative of Enterprise Ireland, Dublin City Council and The Digital Hub Development Agency.’ Generally, it’s a pretty nice place to work, and a great resource for startups and small tech companies.

However, recently, it looks like they’ve been embarking on some innovative, state-of-the-art cost-cutting exercises.

There’s a little canteen area, for companies to make tea and coffee, wash up their mugs, etc. Check out this snapshot from the canteen this morning, courtesy of JK’s phone cam:

Notice anything odd about that bottle of washing-up liquid?

Yum yum! Nothing nicer than washing your mug with a dash of toilet cleaner.

Dumb eco-questions you were afraid to ask

Published November 19, 2008

New Scientist have a great article up this week entitled ‘Dumb eco-questions you were afraid to ask’, including:

Q: Does switching from bus to bike really have any effect? After all, cycling isn’t completely carbon neutral because I’ve got to eat to fuel my legs.

A: You are much better off cycling. A 12-kilometre round commute on a bus or subway train is reckoned to generate 164 kilograms of carbon per commuter per year. Somebody cycling that distance would burn about 50,000 calories a year – roughly the amount of energy in 22 kilograms of brown bread. A kilo of brown bread has a carbon footprint of about 1.1 kilograms, so switching from public transport to a bike saves about 140 kilograms of carbon emissions per year — although this only really works if enough people cycle to allow public transport providers to reduce the number of buses and trains they run.

Also included: ‘How clean does the pizza box/can/bottle have to be for it to be recyclable?’; ‘Are laminated juice cartons recyclable?’; ‘What’s worse, the CO2 put out by a gas-fuelled car or the environmental effects of hybrid-car batteries?’; ‘Can I put window envelopes in the paper recycling?’ and many more. Check it out…

VisitWicklow.ie: Spammers

Published November 17, 2008

I think I just got my first spam from a government body! Specifically, VisitWicklow.ie spam from Wicklow County Tourism. It says:

Wicklow County Tourism is launching its sparkling 2008 Christmas campaign this month, with an extensive festive section on our website www.visitwicklow.ie/xmas . Here you will find all the information you need about what is happening in the Garden County this season including Christmas parties, seasonal events, carol singing, festive markets, Santa visits, great accommodation packages etc.

It was sent to a spamtrap address, scraped from an old mail archive. This address is a dedicated spamtrap; I’ve never used it for non-spam-trapping purposes, nor has it ever opted-in to receive mail. So there was no question that I granted permission to anyone to mail it.

The address delivers mail to my personal account — that’s what I do with my spamtraps, until their volumes get too high. So it still qualifies as a "personal email address". Here’s the full spam with all headers intact.

It appears the message originated at IP address 87.192.126.62:

Kilpoole Hill appears to be south of Wicklow town, just the right spot for a wireless tower used for Irish Broadband access from The Murrough, Wicklow Town (mentioned as the address for Wicklow County Tourism in the mail).

Suggestions? Did anyone else get this? How do I report spam sent by the Wicklow County Tourism Board?

Update: they also hit the Irish Linux User’s Group submission address. I wouldn’t be surprised if they scraped the addresses of other ILUG subscribers, then…

Déjà Joué

Published November 11, 2008

James Tauber just mentioned on Twitter:

“is it bad that I just saw a photo of Stockholm and immediately recognized a stretch of road from PGR2, rather than when I was actually there?”

This is something I’ve been thinking about recently. As game graphics improve, the realism levels become close enough to fool our brains into creating something like "real-world" memories for the worlds we’re experiencing in gameplay.

For example, when I visited California for the first time, I was stunned by the feelings of familiarity I felt in response to stuff I’d experienced while playing the super-realistic Grand Theft Auto: Vice City; little things like the way traffic lights were mounted above the road, the design of the curbs, etc., the level of detail for which Rockstar received a "Designer of the Year" nomination — because of this, the streetscape of a typical Californian street was instantly familiar to me.

The same thing happened this weekend, watching footage on TV of Arizona’s Monument Valley. Naturally, I’ve driven a dirt bike around Grand Theft Auto: San Andreas‘ version of this. ;)

Update: another one is the Pripyat level of Call of Duty 4, which would be extremely familiar to anyone viewing these photos from a real-life visit.

I think this phenomenon needs its own name. "déjà vu" is similar, but different — that phenomenon occurs when the memory feels erroneously that an experience has previously happened, whereas in this case, the experience has happened — albeit virtually.

I’ve come up with a phrase to describe this: "déjà joué". (In French, that’s "already played", analogous to the "already seen" of "déjà vu".)

What do you reckon? If you like it, feel free to use it ;)
