Bingo. I had a very similar problem on my train journey tonight, but related to packet loss instead of latency. Both the WiFi on the train and my 3G cut out at various points, often diverging in coverage as the journey progressed. If such a solution, which sounds a lot like channel bonding (as mentioned by another poster) is available, it would seem to cover this scenario as well. Imagine the implications for mesh networking as well - or is this something already dealt with in MN?

I have experienced the same sloth, albeit on fairly full buses. 1 hour to get 8 miles. Why? Because the bus stopped every 5 minutes to drop people off. It wound round nearly every single estate in town. Even though the volume of traffic on shared routes would support many more alternate services with fewer stops, if everyone were to abandon their personal vehicle.

Of course, that's a big if.

I suppose I should have qualified my statement. I was referring to a situation where a significant fraction of people taking a journey actually choose to use mass transit to do so. From the same page:

"A commuter service in Santa Barbara, California, USA, found average diesel bus efficiency of 6.0 mpg-US (39 L/100 km; 7.2 mpg-imp) (using MCI 102DL3 buses). With all 55 seats filled this equates to 330 passenger mpg; with 70% filled, 231 passenger mpg.[60] "

Additionally, it need not be combustion-powered mass transit, but rather shuttle-or-train type transport, similar to the Chinese concept mentioned above. Again from Wikipedia:

"Considering only the energy spent to move the train, and taking as example the urban area of Lisbon, train seems to be on average 20 times more efficient than automobile for transportation of passengers, if we consider energy spent per passenger-km.[57] Considering an automobile which has a consumptions of around 6 l/100 km (47 mpg-imp; 39 mpg-US) of gasoline, the fact the on average cars in Europe have an occupation ratio of around 1.2 passengers per automobile and that one litre of gasoline amounts for about 8826 Wh, one gets on average 441 Wh (1,590 kJ) per passenger-km. On the other hand, a modern urban train with an average occupation of 20% of total capacity, which has a consumption of about 8.5 kWh/km (31 MJ/km; 13.7 kWh/mi), one gets 21.5 Wh per passenger-km, 20 times less than the automobile."

Think about all the traffic jams that exist in busy cities, and how much less congestion there would be with an organised public transport system where each passenger takes a fraction of the space.

This - so much this. For popular journeys, mass transit is going to be considerably more efficient.

But keep the bubblecars for trips to rural/remote locations, and the elderly and disabled who need door to door service.

Perhaps a shuttle-type tram/train with 'pod docks' would be the ideal combination, maximising takeup, reducing stop frequency and offering end-to-end service for those who needed it.

Well, I lived there six years, and for the first four I couldn't wait to leave, but grew very fond of it in the last two. Not the architecture or the public transport hostile, spread out grid system, but the cultural side of Milton Keynes appeared to be flourishing in that time, and appears to continue to do so.

Numerous art centres, live music venues and leisure facilities, an active centre of business of commerce, and engulfing and adjoining various very pretty, but relatively affordable towns such as Stony Stratford, Woburn Sands and Newport Pagnell. But perhaps that's a grass-is-greener view now that I'm stuck in a sleepy town in South Bucks. If nothing else, you could get the hell out of the place really quickly using the express train on the Euston line.

I think part of the cultural expansion is the financial vortex effect of London, pushing prices up throughout the home counties. It's about the first place outside the London ring of property inflation that the unsavoury artistic classes can afford. But I guess I shouldn't say any more, lest it becomes the next Hoxton...

Not seen any evidence of this, other than the lack of security updates for browser-plugin based vulnerabilities on Oracle's part. Out of curiosity, if you mean server side Java as well as client-side java, could you cite references? This is not to doubt there are big issues with the JVM, and the seeming sloth of response of Oracle to some of them - I'm just wondering what the vast amount of server-side infrastructure would do if the JVM were to be EOLed. In terms of relatively high performance, managed platforms, given Microsoft's flight from CLR, what are the alternatives? And why does Oracle seem so indifferent?

He was referring to liberals as the hissy-fit throwers, and actually casting Christians in a beneficent light. As a liberal I could report the former, but I believe too much in free speech. As an atheist with qualms about organised religion I do object to them taking over the role of the state, but I'm glad that someone is providing people with the means for self-education. As long as there is no interference on the subject matter (evolutionary biology for example) and no attempt to proselytize this is a good thing.

Seems an interesting idea for long recordings needed in a hurry, but the transcriber will be losing possibly important contextual cues by reducing the length of the utterance. Also, there is a great overhead per-person in terms of manual labour (waiting for audio to buffer, HCI interaction, etc). On the upside, it might be less dull to listen to shorter, more varied recordings than one long one. But it would suck to transcribe half a murder-mystery.

He who has but four and spends five has no need for a wallet.
