Computer fan motors are brushless DC. But really they are permanent magnet AC motors with a simple VFD (variable frequency drive) in it. I suspect RC planes are the same.
In the industrial world VFDs are very popular. On anything from a 2HP conveyor to a 1000HP+ piece of equipment. They rectify three phase input to DC, then convert it back to AC at the desired speed. Some are setup so you can have one central rectifier, and multiple inverter sections for your different loads.
That's twice the cost of the digital download. There's no cheap option for new Macs.
One can create their own recovery USB or DVD, but based on years of Windows experience, many people won't, and most people complain about having to do it. So it's not like not shipping an install disk is a new revolutionary Mac only feature.
Novices have a LOT of trouble burning non-music CD's.
Novices have a lot of trouble burning music CD's. Not closing the disc is but one of the problems. Frequently the problem is burning it as a data CD. You know, 18 MP3 files in ISO9660 format.
Some can't understand the concept of an MP3-CD, a data CD with 100MP3s on it, and a portable or automotive player that can read it.
Couple things going on here. Sounds like Lion has built in recovery partition is the first thing. The second thing is it sounds like the firmware on new Macs includes sufficient smarts to connect to the internet to restore the OS to a blank hard drive. " Internet Recovery" they call it. Not really a feature of Lion because it's built into the firmware.
Unfortunately it sounds like options are limited to get OS install media, in case, you know, you don't want to wait 5+ hours for it to download.
I've been blown away by McMaster Carr's delivery time as well. I think they ship by teleporter. As far as I know they don't have a Canadian center. I've ordered things at 4PM, and had them delivered by 10AM the next morning to a rural Canadian town
I had a file someone else accidentally deleted off the server. Called the help desk to put in a ticket to restore the data. Push come to shove the sys admin couldn't find the tape for that week (I think it was a diff tape). Didn't give me a lot of confidence in their backup system and I started my own squirreling away backup.
It's ideal in Windows? In Chrome the flash plug in will gradually climb in RAM consumption until it slows down the computer or crashes the plugin (over 1GB)
Flash is unviable even on a PC platform. Watching Youtube videos Flash's RAM consumption can climb over 1GB, and the CPU usage will be 3x what it would be to watch the video in VLC.
The Windows 7 throbbing splash screen is 1024x768 and loads before "proper" video drivers are loaded, so I think it's a VESA mode, and you get a fall back 640x480 splash screen (like vista) when booting an i810 in Windows 7 (even with drivers installed). During Windows 7 installation and before you install proper drivers for your GPU you get 1024x768 but you do get poor performance, from the VESA driver, but with i810 you're limited to 640x480.
Don't get me wrong, I've never thought of i810 as a "good" GPU. i810 is part of a long lineup of crappy GPUs from intel: Intel740 was a crappy standalone version of it. -All sorts of crappy graphics cards marketed "Extreme Graphics" -GMA900 notable for it's lack of WDDM drivers and lack of Aero, but marketed "Vista Capable" -GMA950 that was crappier than comparable ATI and nVidia bargain chips, and represents the worst chip that can run WDDM -GMA500 Decent hardware for the application (netbooks and MID) but terrible Windows and Linux driver support.
The site mentions dropping Intel i810. I still have some PIIIs running with i810 GPUs. Now granted I don't run anything newer than XP on the computers, I have tested, and it will work with Windows 7. Windows 7 will still load XP/2000 drivers for GPU, audio, network. Intel i810 without drivers limits you to 640x480x16 colors.
Wasn't the point to update the computers? So how does this differ from running old computer with old Microsoft software? For example Windows XP and office 2007 (or 2003) will still work fine on a PIII with 256MB RAM.
People talk about how Linux can "breath new life" into old computers, but in my experience new distros get bloated just like new Windows versions.
No, unlike cynyr I have a normal thermostat (similar in appearance to this, though it's dual gauge imperial/metric http://c3.ac-images.myspacecdn.com/images02/64/l_bc1694bf480c462abfab95dbc06f7d2a.jpg ). When I'm done with heat for the season I set it to its lowest setting. When I want heat in the fall I set it to 20C and eventually the apartment will even out to a nice comfort level.
As well I'm on the bottom floor, so most "heat loss" just goes to heat the unit above me, so I don't know if there's even much of an environmental savings.
There are a fair number of people who don't pay for their utilities when they rent apartments. This is especially true in buildings that have minimal individual temp control. I don't need to pay for my utilities. I'm pretty sure that in general I'm less careful about say not leaving windows open than I would be if I had to pay for using heat dumping as a way of cooling my apartment when the heat is too high. I feel guilty about that doing that but hey. In a similar vein, I suspect that lots of people who do control the temperatures would keep them down if the thermostat instead of displaying just the temperature displayed the actual cost accumulating. That's probably a lot technically simpler than trainable AI.
I live in an apt with baseboard hot water that I don't pay for. There's one manual thermostat in my unit and it takes a while for the heat to be even throughout, so I found it best just leaving it set to 20C unless I'm going to be away for weeks. If I were paying for the heat I would probably install a programmable thermostat to try and save, but I'm not as wasteful as some of the other tenants in my building that set it to 25 and leave the windows open.
If I had a programmable thermostat it would be 15 at night and during the day, 20C first thing in the morning and in the evening. Not much learning to go on. It's not like I'm a woman that goes "Brrr" when the temp is 21 and set it to 30.

The current system intentionally encourages exercise! Two or more round trips when you find them occupied.
I assume managed switches and such would prevent that from damaging other clients.
Was Reading The Title really that hard?
What type of transit bus? New look?

So you carry several laptop sized DVD/CD wallets instead?

Your computer storage closet is underneath the kitchenette?
Did it round off fractions of cents from every transaction too?

It's shit on a PC. If a dual core PC struggles to keep up how could anyone ever imagine it being usable on a handheld.

For "high" resolutions like 1024x768x32bit? I ask this seriously because on the windows side it certainly doesn't seem to run such VESA modes.
