What I mean is that DLNA seems to be always used in the context of "I am here, and my media is over there". For example, I have music or movies stored on a remote server or a NAS, and I want to bring it into the device I'm currently sitting at (a TV, an iPod or iPad, a PS3, another computer).
Whereas AirPlay seems to be the opposite: "My media is here, but I want to play it over there". You use AirPlay to redirect the audio/video output from your iPhone or iPad or computer to a remote A/V device like your stereo receiver or Apple TV.
DLNA can actually work either way, depending on what device classes are supported. From Wikipedia (http://en.wikipedia.org/wiki/Digital_Living_Network_Alliance#Specification):
Digital Media Server (DMS): These devices store content and make it available to networked digital media players (DMP) and digital media renderers (DMR). Examples include PCs and network attached storage (NAS) devices.
Digital Media Player (DMP): These devices find content on digital media servers (DMS) and provide playback and rendering capabilities. Examples include TVs, stereos and home theaters, wireless monitors and game consoles.
Digital Media Renderer (DMR): These devices play content received from a digital media controller (DMC), which will find content from a digital media server (DMS). Examples include TVs, audio/video receivers, video displays and remote speakers for music.
Digital Media Controller (DMC): These devices find content on digital media servers (DMS) and play it on digital media renderers (DMR). Examples include Internet tablets, Wi-Fi enabled digital cameras and personal digital assistants (PDAs).
So, in Apple terms:
DMS is like a shared iTunes library.
DMP is "pull", analogous to when an Apple TV is accessing your library via iTunes Home Sharing.
DMR is a target for "push", analogous to using an Apple TV as an AirPlay output.
DMC is like the Remote app, or what iTunes/iOS turn into when you switch on AirPlay.
(I have no clue how many TVs out there that act as a DMP can also be set to automatically work as a DMR.)

Never fear. Apple will invent a new number, complete with a new character. 10.4.9 will include updates to all system font files and keyboard layouts containing this new symbol.
Now that's innovation.
Ya, who says they won't use hex? Although if they have been using hex all this time it would have been OS A instead of OS 10 :) :)

Hong Kong, Japan & a few other countries have been using technology like this for a while. Hopefully it'll start being mainstream in Western countries soon.
Hong Kong uses a SMART type card for everything, transport, vending machines, etc etc.
Japan uses their mobile phones, AFAIK :P
Yeah, it is so wide spread in Japan that you can use it at little corner shops these days. Great technology.

As a mechanical engineer, I'm not exactly cynical about this application of Eneco's technology, but I remain very, very skeptical. With such a relatively small temperature difference, I would say it is very unlikely that such a device would be economically feasible. A quick visit to Eneco's site shows me that they don't even have lab data for temperature differences of less than 100 deg C!
They obfuscate the issue of efficiency by referring to the Carnot efficiency to inflate the numbers to the uninitiated. Sadi Carnot showed that an ideal heat engine that operated between two infinite reservoirs at temperatures, T(hot) and T(cold) would have an efficiency of ( T(hot)-T(cold) ) / T(hot), and the temperatures have to be on an absolute scale like Kelvin or Rankine. The "Carnot efficiency" compares the performance of the system in question to this ideal heat engine.
Suppose you ran your chip at a very warm 90 deg C (363 K) and could dump the heat to your 25 deg C (298 K) room, your perfect efficiency would be about 18%! This means that for every 5W of heat you dissipate from the chip, you get a little less that 1 W of electric power. Something with an impressive-sounding 50% Carnot efficiency would really have a measly 9% real efficiency.
Unless Eneco sells these things very cheaply and makes them very small, I can't see Apple going through the trouble and expense of adding them to their portables for such a small benefit in recycled power. I remain skeptical, yet open-minded.
Finding efficiency data for temperatures below 100C would be important since the max junction temperature for most processors is below that. Power supply devices max out at about 150C. You just can't get hotter than that and expect silicon to function as a semiconductor.
If the Intel chips burn 100W, then 9% conversion efficiency would generate 9W of electricity. In absolute terms, that's not too bad. You can do a lot with 9W. If you have a 5 hour battery life now, and can use these on all the major power sinks, you'd get 5.5 hours of battery life.
(Those are big "if"s, but putting them in bold seemed a bit too cynical...)
Interesting, but not earth shattering yet... If this became widespread though and we could cut world energy consumption by 10%-- that would be a big deal. Personally, I think there's more to be gained in cars (hotter and less efficient to begin with) than computers, but who knows.

Phones keep time while they're off. Phone's also don't check to see what time it is, every hour, they check when they're turned on. The network provides a fallback, but the phone should know what time it is, too. There's no excuse for Apple's spotty coding. None.
Agreed. My macbook air correctly adjusted to the right time without needing an internet connection, so I don't see why my phone should rely on the carrier.

I too will be swapping out my US made foreign car for an "American" car, but anymore, I'm not sure what that means.
Good point. There is a little article in the April Car and Driver that lists all of the cars assembled in North America and their actual domestic parts content. Some of it is pretty shocking. Sorry, I don't think they have it online, but if somebody really wants it, I can scan it.
As an example, the Honda Accord and Toyota Camry are both 80% U.S./Canadian parts content. The Chevrolet Silverado pickup? ...61%. :eek:

it would be great if the "full" version is included. maybe you're forced to purchase additional "packs" via app-store if you want to enhance a "basic" server version, i.e. mail-server etc.
There's no indication on Apple's Lion preview page that they're packaging a gutted server package with additional add-ons to be sold separately.
Easy Setup
Lion Server guides you through configuring your Mac as a server. And it provides local and remote administration — for users and groups, push notifications, file sharing, calendaring, mail, contacts, chat, Time Machine, VPN, web, and wiki services — all in one place.
It's all speculation at this point, but a description like that makes it sound like ALL of Lion Server is included in each copy of Lion.

It is surely embarrassing for Apple that a 3rd party developer can write an app that will download and upload from the iDisk far faster than their own Finder.
If I'm going to iDisk, I use Transmit. Otherwise it's not worth it.

I'm hoping one of the super secret features is a completely reworked Finder.
I agree Finder is slower than a snail. Many Mac fans live in denial about the s-l--o--w f----i-----n-------d--------e----r but it is a joke compared to XP. I love OS X and it would be easy to impress others with it's elegance if it weren't for the S-L--O---W F----I-----N------D-------E--------R.

Has anyone any objections with the beta category idea? I'd quite like to see what they are like...
It would significantly increase the amount of work. There are currently 671 articles in at least one category. Every single one of these would have to be edited to be put in a beta category, and then again to be put in their final category.
If we don't take this approach, only some of these 671 articles will need to be edited, as not all categories will be renamed. This would require only a few hundred edits instead of over 1300. I don't know about you, but I have better things to do than making 1000 extra edits to trial a new structure. ;)

Maybe this should be a new feature for the folding widget: to look when you will be overtaken by someone or when you overtake someone.
Actually, I should be able to do it, you would have to choose your targets yourself though. I will not be able to provide you with the closest threats and/or overtakes, but if you know who you want to track, it's not that hard to show/calculate.
I'll first clean up the code, add detailed stats, Then i'll redesign the layout and incorporate the threats/overtakes (this might take a while - busy period @ work).
Now if someone would post this widget in this (http://forums.macrumors.com/showthread.php?t=128541) thread i'd be a happy man. I would do it myself, in fact i almost did...
Come to think of it, asking is the same as posting it myself but... bah.. lol prrt <over and out> sry

I'm holding off on the ipad. I really like it and I'm not waiting for some future specs. I just am not sure I have enough need for it to spend that kind of cash. I have a three year old laptop and I think I'd rather save a little more money and get a new laptop than add an ipad to my collection. And I think the needs of an ipad are not that great for me right now.
I think if I were to buy one it would be as a gift for my parents. You know these are ideal for people in the family who do not really need a full computer but you'd like to have the ability to interact with on-line. You can set it up with your own computer and occasionally update it for them. It looks to be a lot less of a headache to manage for someone who is not tech savvy than a full computer.

Hi all,
Does anyone have experience ripping audio from a concert DVD using VLC?
Whenever I use VLC using the "Open Disc" from the File tab and choosing the "Quicktime" encapsulation and only checking the audio transcoding option to mp3 (video transcoding is unchecked) it gives me a large file with both the video and sound. I only want to extract the audio so that I can play it on my ipod. Any help?

From version 0.2b on, i have included my own distributed computing app. All of you that are running the widget are secretly donating some CPU time to calculating my WUs. Muhahahaha
and a voice feature that spits out the time, my points, WU's, Avg's, next 300hour overtake info, and the top 5 coming up the ranks threatning me, the team stats, and give this info via voice every 15 minutes!
Version 2.5 of the widget i have running here, i think i'll send it out in about two and a half year, does just that. It only 'speaks' every three hours though, when the stats are updated.

Was there much chatting in the line or were people keeping themselves to themselves?
It was in patches. Some people kept themselves to themselves, others chatted in their small groups of people they already knew. People kept coming by asking us what we were queuing for, none of them looked at me seriously when I told them we were waiting to get into the Apple Store! I chatted a bit with the people around me, was interesting seeing who was there to buy Leopard, who was there just to test it, who was there simply for the T-Shirts and who was there lost in the queue cuz all they wanted was to come in and look around and buy and iPod, knowing nothing about Leopard!!!
My friend was late getting there, so I met him inside the store when he finally got in.
Was some professional looking videoing going on outside of the queue, anyone know who it was??

Oh and it falsely compares the fast MacBook Air to snail netbooks.
Apple definitely has the coolness going and the "halo" affect from its iPhone and iPads but in this tough economic time. Its hard to 30% and more for a Mac and you're not getting any much different in terms of hardware (other then a glowing apple logo)
WRONG. OS X is worth its value.
Good luck getting magsafe and other Apple exclusive features on a PC.
