The key thing to remember though is that in a traditional shutdown, we close all of the user sessions, and in the kernel session we close services and devices to prepare for a complete shutdown.
Now here’s the key difference for Windows 8: as in Windows 7, we close the user sessions, but instead of closing the kernel session, we hibernate it. Compared to a full hibernate, which includes a lot of memory pages in use by apps, session 0 hibernation data is much smaller, which takes substantially less time to write to disk. If you’re not familiar with hibernation, we’re effectively saving the system state and memory contents to a file on disk (hiberfil.sys) and then reading that back in on resume and restoring contents back to memory. Using this technique with boot gives us a significant advantage for boot times, since reading the hiberfile in and reinitializing drivers is much faster on most systems (30-70% faster on most systems we’ve tested).
Microsoft also offers up some data showing how much faster this mode is compared to a normal cold boot:
Microsoft is pulling this trick off by dumping the BIOS and instead going with UEFI (Unified Extensible Firmware Interface):
One thing you’ll notice in the video was how fast the POST handoff to Windows occurred. Systems that are built using Unified Extensible Firmware Interface (UEFI) are more likely to achieve very fast pre-boot times when compared to those with traditional BIOS. This isn’t because UEFI is inherently faster, but because UEFI writers starting from scratch are more able to optimize their implementation rather than building upon a BIOS implementation that may be many years old. The good news is that most system and motherboard manufacturers have begun to implement UEFI, so these kinds of fast startup times will be more prevalent for new systems.
Here it is in action ... it's very fast:
The notebook used in that video is an EliteBook 8640p (Intel Core i7-2620M, 8GB, 160GB SSD).
Do you have problems with dust buildup in your graphics cards? Then MSI's N580GTX featuring ’Dust Removal Tech’ might be just what you're looking for.
How does it work? It's actually pretty simple:
When the system is turned on, the graphics card fan will rotate in the opposite direction for 30 seconds. By running in reverse, the fan helps to remove dust from the heatsink fins to ensure optimal cooling every time.
The new fan blades are suppose to offer 20% better airflow.
Here's a game I suggest you pick up if you like the zombie/survival genre - Killing Floor.
It's not a new game (2009) and the the graphics aren't Crysis 2 (You know why? Because only Crysis 2 is like Crysis 2!), but I guarantee you that if you like blasting the zombies, then you're gonna love this!
It's mostly a co-op survival game, but there is a very nice solo mode for those not into the group gaming thing.
I've only had this game a few days but it's not an instant favorite. If you've played Left 4 Dead or Left 4 Dead 2 then this game will feel familiar (because you're shooting zombies ... durr!) but in my opinion this game is better on all levels - there's no over the top stereotype characters, the maps are a good size, the gameplay is freer and more open, the guns are good and there's a nice selection, the sounds are meaty and visceral.
All in all a really nice game!
Pick it up from somewhere like Amazon.com or Steam ... it'll set you back less than $20. You won't regret it!
Could you live a day without technology? Could you put the cellphone, computer, iPod, TV, Twitter and Facebook (yes, abandoning your farm for a day!) away for a day?
A survey carried out by Intersperience suggests that giving up technology is like kicking an addiction.
The project also involved qualitative research, including challenging participants to get through one full day without using technology. Giving up technology was considered by some to be as hard as quitting smoking or drinking, while one survey participant described it as “like having my hand chopped off” and another called it “My biggest nightmare.”
