@figuerres:I have contradicting experience. With hardware RAID(A brand, P brand and S brand, from low to high-end models) I had experienced 4 RAID fails in 4 years (the harddisks are readable, just the RAID card refuse to read them as RAID group)
On the other hand, the server with Windows built in software RAID never failed once.
The only case that I'd choose hardware RAID over software one is when the CPU will have something more important to do (Say, in the case of a SQL server).
SAS is also nice and reliable, but I guess because of price issue, not much people will have that at home.
I have not much experience with NAS, so no comment on that.

Just with 2 exceptions: password and upload fields.
I remembered 10+ years ago, my boss what me to keep all field values when user press "back"button (on the page, not on browser). When he saw the file selection in upload controls aren't preserved, I have to spend quite some time to explain that this cannot be done because it's explicitly set to behave that way to block the local information exposure vulunability found in the days of IE3.
I do not know how ISP manages the IPs. But, from my stupid lack of knowledge, I expect the IP address are like a home address. They are virtually mapped to the geo location, otherwise I think the routing will be inefficient as you have to keep track of each IP at different physical location. Meaning, IP is still designed like a home address and telephone number, they are geo encoded for routing purposes. So, I guess the first section of your 128 bits have to take care of that. If not, please explain to know how to route an IP address efficiently without geo encoding, because ultimate the servers are physically located somewhere in the world, the cloud is a lie.
Actually after an ISP has bought the IP range, how to use the range is really up to them.
Take China for example, if you use an old IP map, you'll see some people in Shanghai sometimes got IP mapped as HeiLongJiang (somewhere in northeast of China). That's because that ISP just assign the next new range of IP when a new service area is implemented. So with IP address, while it can usually accurately reflect the country it belongs to, if you need more detailed information, you nearly always have to get assistance from ISPs.
And btw, keeping the IP ranges together is important for Router Information Protocol to work effectively. Can you imagine if "1 ABC street" is in one country but "2 ABC street" goes to another?
Linux source code used to be like that.
In the old days there's even more interesting discussions appeared as comments in the source code. (The famous one is the challenge on emitting kernel panic messages through HDD LED in form of Morss Code... and someone actually took the challenge and implemented it later)
Now the old comments are still there, but they tends NOT to use source code as discussion board now. :P
EDIT: I just found that there's someone submitted update for 2.6.29-rc1 that makes it not only just blinking HDD LED, instead blinks ANY LED it can find. Brilliant work!
You give the ISP the name you want, and they give you the IP address (generated using the well known hashing algorithm). As I said, collisions should be very rare, and practically non-existent with 256 bits so I don't think there will be a need for mass suing.
As for which IP across the globe would be the best based on the location, just like today, we can make the country code top-level domain a part of the chosen name. Nothing about what the domain names look like today need to change. Only thing is that once you know the name, you also know the underlying real IP address, removing the requirement for a DNS server.
You're assuming IP addresses are free, when they're not. ISPs paid huge fee to buy their IP ranges that, is hidden cost of your monthly internet fee.
Not seeing the extra 100GB option, but I have 48GB already so I'm already happy.
Not aware that I have to update the WP8 app to OneDrive as the MarketPlace is not prompting me to update, strange...
I DO hope that after they rename the App, I don't have to retype the password again because my Live password is somewhat inconvenient to be inputted on WP8 screen keyboard.
Oh the 16:9 displays...
Last year my 17 inch 4:3 LCD is dead and I went to computer shopping arcades (the arcades that is full of computer shops). To my surprise only 3 out of the 60+ shops still have 4:3 LCDs for sale, and out of the 3, 2 of them is still selling CRT displays.
I don't really understand why people go for 16:9 or 16:10. It's good for TV but if your primary purpose of computer is for document processing, 16:9 or 16:10 display actually offers much smaller screen area than 4:3 versions. And if you play MMORPG games and suddenly have to switch from 4:3 to 16:9, you'll instantly find your vision becomes much much "short sighted" that if you use long range attack, you suddenly found your enemies goes out of screen when you want to use your longest range weapon, that you have to adjust your camera angle to see them. (In these games you'll usually want to have camera set to around 35 degrees downward so you can see the traps/ranged attack indicators on the floor more easily, and you can click on the ground to move easier. In 16:9 displays I have to make it 10-15 degrees less downward so it affects my gameplay experience)
And you know what, the selling price for 4:3 display is actally cheaper than the 16:9 models.
I don't really understand why people ever want to buy a 16:9 / 16:10 display for their computer.
@DeathByVisualStudio:If that's because of profit margins, there would have been small amount of "testing market reaction" models released to the wild, but I didn't see anything like that yet.
There could have been some kind of technical difficulty, but for price? I don't think so. There are always some customers that like the latest shiny things and don't have concern on price. I knew of a few such customers back when I worked in computer shops.
@GoddersUK:If "Touch" is not only accessible from Notebooks/All-in-One PCs, I'd probably like it. It's pretty strange that no major LCD suppliers providing displays with multitouch support yet.
IMO, Microsoft should blame the display manufacturers for failure on Metro.
