We've seen countless attempts to build a better lithium-ion battery, but there's been far fewer research efforts devoted solely to figuring out why lithium-ion batteries don't last longer. A team of scientists at the Pacific Northwest National Laboratory have been doing just that, however, and they're now sharing some of their findings.

Gary Marshall: Chrome OS: what's the point?

<img src="http://cdn.mos.techradar.com//classifications/computing/software/operating-systems/images/Chrome_OS/chrome-cr48_crop-200-200.jpg"> There's an old saying in marketing: sell the sizzle, not the sausage. Google's <a href="">Chrome OS presentation</A> reminded me of that. We spent ages watching Google grind up some testicles, bits of bone, chopped sawdust and the odd factory worker's finger before shoving them into a big machine, but nobody spoke about how tasty sausages are or fried up a few tasty links. We saw the sausage. Where's the sizzle? There was a telling bit in the post-launch Q&A, where the Google team were asked why someone should use a New York Times web app in Chrome when they could just go to the New York Times website. There was humming. There was hawing. I was half-expecting someone to say "Damn, we hadn't thought of that. Cancel the project!" with security goons rushing in to bring the session to a premature halt. That didn't happen, but it really was a good question. Chrome OS is undoubtedly clever and Google's giveaway of lots and lots of Chrome notebooks is very nice, but what exactly is it the answer to? It's here. Now what? I suspect the problem is the iPad and the rise of the tablets. Most questions to which the answer could be "Chrome notebook" can also be answered "iPad" or "Android tablet". What boots faster than a traditional PC (the answer to that one also includes "MacBook Air" and "Anything with solid state storage")? What runs web apps from an App Store? What sleeps and wakes instantly? What's very secure and very unlikely to get viruses? What's really portable? What has great battery life? What can access the enterprise systems from a secure yet friendly interface? Who lives in a pineapple under the sea? You get the idea. Even the Web Store looks like a very slightly tweaked iTunes. It's easy to make predictions that blow up in your face - remember "No wireless. Less space than a Nomad. Lame" about the iPod? - but while there are obvious benefits to enterprise customers, I'm struggling to see how this is going to appeal to consumers. Mobile phone subsidies will make it as cheap as chips if you look beyond the pricey data contract, I'm sure, but the networks subsidise netbooks, normal laptops and iPads, too. I really can't see why you'd want a Chrome OS notebook when you could buy a normal notebook and run the Chrome browser on it - or skip notebooks altogether and go with a tablet instead. Maybe it was just an underwhelming presentation and Google's got a marketing plan that's going to blow everyone's socks off. I do hope so, because more tech, more competition is always good. But I can't help thinking that Google's reinventing the netbook just as everybody who wants a netbook has bought one, and just as everyone who might have thought about buying one has either bought or started saving for a tablet. If I'm right, Google isn't shutting the stable door after the horse has bolted; it's erecting a precision tooled, state of the art stable door in an empty field.

Check Point Software Technologies

You must have heard about the TCP/IP protocol. In all kind of transactions the internet is the key product. You will definitely be able to find out that at each layer there is some protocol working. Let me also tell you that you will definitely find out that there is some sort of protocol working at each level. You will be quite thrilled to know that each layer has its own importance and you will not be able to install one layer without installing the previous layer. Now as far as the checkpoint is concerned it is definitely related to security measures.The electronic checks use the ACH channel which is supposed to be quite safe. But, would you like to know that how this software become so powerful? This is because of the firewall, gateway as well as the routers which are being used at the check points like data link layer or network layer.1. FirewallIt is a device which is used to filter out the information which is being accessed from the network. You can deny any information which you find out to be malicious. I really feel that you will definitely have come across the firewall. There are several kinds of firewall techniques like packet filter, application gateway, circuit level gateway, proxy server etc. you should also know that the firewalls are being installed at the network layer.2. GatewayIt is a computer or network that allows the controlled access to another computer or network.3. BridgeBridge reduces online traffic on the LAN by dividing it into two half. The bridge works at the data link layer of the OSI model. It checks the incoming traffic and decides whether to discard it or not. The bridge offers four or more hardware ports.4. SwitchesThe switches are generally called the multiport bridges. They offer more than four hardware ports. They are used in the creation of LAN.These are some of the hardware that is used to give the network the security which it requires. As far as the check producing software is concerned, it is definitely in need of security. The main reason why it has become so popular is the safety which it provides. It is all done with the help of the ACH channels. However the ACH channel uses the hardware which I have discussed above. All of them are being used for the purpose of security as well an implementation of network.Once a secure network is established then you can always go for the check printing software. Believe me that it will definitely be very comfortable for you.	 	 		 			 				 					 						Looking for how to accept <a href="http://www.q-check.com/" target="_new">Checks by Phone</a>?
