Should I Run a Second Operating System in a Virtual Machine or Dual Boot? Dear Lifehacker, I've seen you talk about running Windows on a Mac by dual booting, as well as dual booting Windows 8 alongside Windows 7. But you've also talked about how to run Windows 8 in a virtual machine. If I want to run a second operating system, which is better? Sincerely, Double TroubleP Dear Double,P It's not quite a matter of which is "best", but—as is often the case—which is better for your particular needs. Dual Booting Is Great for Games and Other Long Stints in an Operating SystemP Dual booting, which involves separating your drive into two sections called partitions, essentially lets you run two operating systems on one computer completely separate from one another. As such, you're getting the most out of your hardware by dual booting, since neither OS will slow down the other in any way. Virtualization Is Great for Running That One Program, or Testing Out a New OSP SExpand The big downside of virtualization is that it's quite a bit slower than dual booting. P.S.
Why Is Wi-Fi Coverage So Bad in My House, and How Can I Fix It? If you and your router are on different floors - and it has removable antenna(s), you want as low a DBi antenna as you can get. DBi is antenna boost, and it's not magic - for a dipole (that's what you have, probably) DBi is increased horizontally by sacrificing vertical. Try an external wifi adapter on your laptop. More useful if the issue's distance, but a useful gizmo when you're traveling, and find yourself somewhere where someone's kind enough to leave their router open but it's just a tad too far. Stick to channels 1, 6, or 11. Try an N router. DD-WRT plus an inexpensive router's the cheapest way to get a repeater. TightVNC: VNC-Compatible Free Remote Control / Remote Desktop Software
Hotspot (Wi-Fi) A diagram showing a Wi-Fi network Hotspots may be found in coffee shops and various other public establishments in many developed urban areas throughout the world. Public park in Brooklyn, NY has free Wi-Fi from a local corporation Public access wireless local area networks (LANs) were first proposed by Henrik Sjödin at the NetWorld+Interop conference in The Moscone Center in San Francisco in August 1993. Sjödin did not use the term hotspot but referred to publicly accessible wireless LANs. The first commercial venture to attempt to create a public local area access network was a firm founded in Richardson, Texas known as PLANCOM (Public Local Area Network Communications). The founders of that venture, Mark Goode, Greg Jackson, and Brett Stewart dissolved the firm in 1998, while Goode and Jackson created MobileStar Networks. The public can use a laptop or other suitable portable device to access the wireless connection (usually Wi-Fi) provided. Free hotspots operate in two ways:

Power on Computer from Internet Now that we live in the broadband era, working in an Internet enabled environment has become a daily routine. It seems that our computers breathe though the Internet connection. Need a new software? The required ingredients involved were: a PC, an Internet connection (preferably broadband) and another remote computer which should have acted as client. the effort would have been in vain. Wishing to provide you with as many useful tricks as I can, I have decided that a helping hand is needed for the situation mentioned above. This hardware feature permits the computer to be switched on through the network. How does the process work? In order to remotely power on your computer you need to send a "magic packet". Do it yourself Before attempting to do the awakening you need to prepare your computer to be responsive to the "wake up" command. Now you just need an application to help you send the magic packet.

Turning on computers remotely Posted by Steve on Wed 20 Apr 2005 at 08:42 To save power it's often useful to turn systems off, but of course when you do that you cannot use them! This is especially frustrating when you turn off a machine which is physically remote from you, but it doesn't need to be. "WakeOnLan" is the term which is used for remotely powering on machines, as this is done by sending "magic network packets" to switch on machines. To use wakeonlan you'll need either: A network card which supports WakeOnLan, which usually has a jumper which connects to your system's motherboard.An on-board network interface which supports this functionality. Many modern systems with on-board NICs support wakeonlan, but it must be enabled in the BIOS. If you have the requisite hardware support can see if it's enabled by your system by running the ethtool command, this shows whether the wakeonlan option is supported by your card, and whether it is enabled. If you don't have this installed run: apt-get install ethtool
Setting a static IP address on the Playstation 3 It is very important to setup a static ip address, if you are going to use port forwarding. When you have port forwarding setup, your router forwards ports to an ip address that you specify. Without setting up a static ip address port forwarding will probably work when you initially set it up, but after restarting your PS3 it may get a different ip address. When this happens the ports will no longer be forwarded to your PS3's ip address. So the port forwarding configuration will not work. What is an ip address? Dynamic vs Static IPs Most routers assign dynamic IP addresses by default. Setting up a static ip for your PS3. Step 1: Turn on your PS3, and then navigate to the Settings option on the main menu. Step 2: Move down this list to Network Settings. Step 3: After you have selected Network Setting, move to the right and select Settings and Connection Status List in the list that comes up. Step 4: Write down the IP Address, Subnet Mask, and Default Router displayed here.
Wake on LAN: Quick Way to Power Up Computer Remotely Custom Search Wake on Lan (WOL) is the implementation to power up your computer remotely from other computer within your home network or over the Internet by using special packet, called magic packet. On this article, I will show you how to power up your computer (remote computer) in your home network by using WOL implementation. Is there any requirement? You can only do this if that remote computer’s motherboard and Ethernet network card support the WOL feature! Let say in your home network, you have computer A and computer B that are connected to network by using network cables. Remote Computer – Need to Enable Wake on LAN feature 1) Let’s talk about WOL support on computer motherboard first, you can usually locate and enable it under Power Management section on motherboard’s BIOS setup page. If you fail to locate this setting and your computer is pretty new, then most probably this setting is supported by default. Here are some WOL examples on motherboard’s BIOS settings: 2) Ok..
Know Your Network, Lesson 1: Router Hardware 101 Home networking is something we all have to deal with, but it can be confusing as heck. This week, we're going to turn you into a networking wizard, starting with getting to know the most important device on your network: the router. P Router BasicsP Your router is the glue that holds your home network together. Devices that connect to your router—that is, the computers, tablets, smartphones, DVRs, game systems, and so on—are called clients. Routers have a number of different features, so we'll go through some of the most common router specs and how they affect your home network.P Wired vs WirelessP SExpand You'll want to hardwire any computer that doesn't need to move around, like a desktop, since wired connections are fast, reliable, and cheap. Most people have a mix of wired and wireless devices on their network, so most of our discussion today will be focused on wireless routers. Wireless ThroughputP Throughput is the speed at which a router can transfer data. Wired ThroughputP RangeP
PC Backup: The backup system seems like magic. How does it work? Unlike most backup products that operate at the file level, the Windows Home Server computer backup solution works on "clusters". Clusters are the lower level constructs of the file system. They are usually 4k bytes in size on most NTFS disks. The "magic" you are seeing is a result of the fact that Windows Home Server makes sure that any particular cluster is stored only once on the server...even if that cluster is found on multiple disks and within multiple files. Here's some more detail on how this works: The server side of the solution is a database (not some off the shelf database, but one developed specifically for this application). And this is how 220GB of data spread out across 4 computers can be stored in 98GB of space on your home server.
