Recently I saw an article about cloud technology, then I cannot help but exclaiming: yes that’s it, the essence of Internet is sharing, and it has being giving us more and more convenience. Had a quick brainstorm, make a summary about everything I know about sharing of network:

First of all, terminal, can we consider it as a network? Yes, I think so, although it was happened within one console, but it was a network inside, multi-users, sharing information, the console is a data pool, just like the internet, mass information.

And then it’s ARPANET, we could say it’s a real network, because data flows among computers, and also x.25 protocol.

And then comes to WWW, World Wide Web, after that, we have real Internet, based on TCP/IP protocol.

What’s next, of course human beings need to make improvement, but what’s that? It seems like that this problem is beyond my imagination. But I think recently I have an answer. As I mentioned, we know that the essence of Internet is sharing, and currently we can share nearly everything (of course should be legal) through internet, and we see quite a few of websites have being setup for information sharing, facebook, youtube, photobucket, and all that jazz, including nearly every aspects in our life such as how to build a house or how to catch laptops with your butt O_o. Until recently, I guess Cloud technology gives me a new clue.

I don’t know if you guys familiarized with our networks, for the big joint, there are always routers transmitting data so that one client could receive necessary data in a timely manner, routers calculate hops, bandwidth, timing or other elements, so to decide the best path. For Cloud computing, it is not just redirect data, but offers extra functions, calculation. One good example is the completion of DNA model; it has been completed by the scientists all over the world, each scientist is just like a computer, if computer A sends the request, all the related computers could offer the power to make the calculation, then at last computer A could receive the result. So no matter what’s your rig, you could get the result of your needs, only if you’ve got a fast enough night work. Someone says: My computer could do it without others’ assistance: yeah you can do it, but have you ever considered about other devices? For example, a handled computer or cell phone needs to output 3D model which needs to be rendered for million times, mission impossible? Impossibility belongs to the past. How? Let’s wait to see what’s gonna happen…

Recently my friends come to me for giving some suggestions on what to do when testing a second-hand notebook HP nc6000. They said just for surfing online, movie and war3, I asked why not buy a new one, a netbook? “Dothan 1.6G with 2M L2, and an ATI 9600, 14’’ good for War3, enough?” lol so I could not help but accept this old one instead of Netbook . (They really got the point, instead to choose a netbook.) So here I just want to share the experience what I would do when torturing a second-hand item. Next I will boil it down to a few notes.

OK here we go:

1, For appearance,

Of course, you got to check the appearance, scratches or bumps, original screws, screen, max the brightness to check whether the screen was overused, dim or not, to judge whether it is waiting to die, keyboard, pointstick, with normal functionality.

2, For parts.

This is the point. In case of the laptop is made up of poor quality pieces, my second step is for benching each parts. For the all-around information, you could try Everest or Sisoft Sandra to make sure the specifications are concord with what shows on official website.

SuperPi or Prime 95 for CPU http://www.upyou.it/modules/mydownloads/files/super_pi.zip

memtest for memory http://www.hcidesign.com/memtest/MemTest.zip

HD tune for Harddrive http://www.hdtune.com/ (need to pay for full version)

Nero drivespeed (Nero diskspeed) for ODD,

Needless to say, for G card you need to use 3DMark, which version? Depends on your specs.

Someone may say: just an old notebook, is that real necessary to run that software? Here my gist is to test the stability, since computer runs with all parts above for 3Dmark test, so this is teamwork, not just G chip.

And for battery, take Batteryeater, do not rely on what Windows says, that’s absolutely inaccurate.

You may also check it with other softwares which could read how many times the battery has been charged and drained, and there are still good chances that you got a good one, but don’t expect too much on it. For testing a battery, you could also full load the system with the mentioned softwares above and check the status, to see whether it could dramatically drop from 99% to lower than 10%. If so, gotte only say throw it away or change the cells.

Next is for USB ports, good or bad, and for the rest of the work, you could try Bluetooth, wireless NIC, or other part and interfaces.

I guess you could be satisfied with this machine if it could pass step 1 and 2. Don’t forget to bargain, our goal is to get a great deal on a real gem.
