You're welcome. Hope you like your SSD upgrade. You may wish to take a look at http://forums.macrumors.com/showthread.php?t=1125400
Some older Mac Minis can have the CPU upgraded, but on both 09 Minis (they are very, very similar) the CPUs are definitely soldered on. This kind of info would be shown in a teardown of a Mac (these tend to be done fairly quickly after a new model is released)

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.

Yup, 5:52:11.2 per unit. I ran it in screensaver mode, watching the display for the first 1/2 hour (I couldn't help it - the flashing lights hypnotized me!) and then letting it turn off the display after that. I have yet to try command-line mode (no GUI), which would presumably tweak the speed still further.

I don't buy it; Apple offers the Apple TV for $99 which provides AirPlay.
...and does a lot more than stream airplay. but not everybody is going to buy yet another set-top box. but everybody buys a tv sooner or later -- if apple can get $4+ per set sold, from all the major manus, why not? more TVs sell than ATVs...

no you don't, exchange 2003 and later supports push email like blackberries and no need for pop/imap. and it's probably more supported than using zimbra on the iphone.
Are you doing this on purpose ? You have failed to address all the points I've brought up, including the fact that Push based e-mail is not a Exchange only feature.
Look, if you want to debate this, at least give us a good-faith performance. None of this bad-faith arguing that just's going to go on and on for pages, where you ignore most points and just re-hash and imply your older debunked points.
it's relative cost. almost everyone uses exchange. if zimbra wants the market they need to price themselves very low or offer killer features MS doesn't. how do you even back up zimbra since exchange has agents available from every major backup application allowing you to do online backups
Zimbra was simply an example. And yes, it does support the same Full/Incremental backups that Exchange does. In fact, Exchange doesn't even support anything but full EDB backups out of the box, the per-mailbox backups/restores the many different 3rd party solution offers are based around hacks.
Microsoft doesn't officially support mailbox-level backups/restores (I'll admit my knowledge stops at around Exchange 2003 thank god), without first restoring the whole storage group to a "recovery" storage group/server and then using Exmerge.exe all things to restore to the production storage group :
http://support.microsoft.com/kb/823176
Thank god Veritas/HP/CA created those agents...
I think I'll move you to ignore now. It's quite apparent to me that you're simply going to try to shove Microsoft stuff down our throats without even knowing about the competition (as is obvious by your constant bashing of Zimbra based on assumptions which have proven false, simply because it was brought up as an example of one of dozens of collaboration suites out there).

They do have different EFFECTIVE focal lengths, dependent on the camera sensor size being used, as your quote agrees.
They don't and it doesn't. It says you apply the 1.6 crop to EF-s lenses, just like with EF.

I apologize if this has been covered before but as a new switcher to the Mac I was wondering if simply dragging a folder from Applications and deleting the preferences are enough for a complete uninstall. From years of working with Windows I've come to expect that programs cannot completely be removed even with uninstallers unless a manual search and destroy is initiated or a cleaner is used. Either the program would leave .dll files in the /system directory or there would be long-lived entries in the windows registry. Do any of these situations exist on the mac or have my years as a Windows user corrupted my thinking? Is there something akin to the registry on OS X? If the program comes with an un-installer, use it. If not Just drag it to the trash. It is done.
