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? Dual booting or virtualizing? P 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 Sincerely, LifehackerP P.S.
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 public can use a laptop or other suitable portable device to access the wireless connection (usually Wi-Fi) provided. Security is a serious concern in connection with Hotspots. The safest method when accessing the Internet over an Hotspot, with unknown security measures, is end-to-end encryption.
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? Check Internet? New update? 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. Many modern PCs have the ability to be remotely "woken up" and turned on. "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 don't have this installed run: apt-get install ethtool Once it's installed run it with the name of your network interface: root@lappy:~# ethtool -s eth0 wol g
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? 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.. Note: Ensure that this remote computer is power connected after shutting it down. Return to top!!
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. This is known as "single instance storage" in geeky circles. 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.
What is a backup What is a backup?: There are very few computer users who have never had that horrible sinking feeling when they realise they have just lost a document, or worse still a whole computer's worth of information. The sinking feeling is because you know you haven't made a backup of your files for a very long time. The truth is very few of us are disciplined enough to regularly make a copy of all of our important computer files. It is something which many of us don't really know how to do properly, so just hope for the best and ignore taking action. It's actually very easy to make a copy of our work, also known as making a backup. There are various ways to make a backup, and usually the ultimate goal is having a copy of your important files on a medium such as a CD or device such as an external hard disk. The big advantage of external hard drive and Internet backups is that you no longer need to find a blank CD every time you which to make a copy of your files. What is a backup?
What Cool Things Can I Do with All This Free Cloud Storage Space? I have been trying to figure out a way to use a cloud / file syncing service to automate a way to get all of my ebooks on one device. I have a Nook Tablet, but I have ebooks from other services like Amazon. I can easily strip the DRM (calm down, I paid for these) on my books using Libre, which is great, but right now I have to physically connect my device and transfer them. There is a dropbox app for the Nook, but I want to automate everything as much as possible. Any ideas? Not sure if you can do something similar on the Nook, but maybe you can... I think I can automate the DRM removal using some scripts if can find a command line DRM removal tool for OSX. I'm also trying to do as much as possible without rooting the device. I was assuming Dropbox on the Nook would offer an "open with Nook" option. Thanks for the tip, but like I said, I want to avoid installing another ereader app on a device that already provides that functionality natively. Ohhhh, got it.
Circumvent Wi-Fi Time Limits at Coffee Shops by Spoofing Your MAC Address SExpand Not only do free WiFi points kick you now and then, they seem to be getting slower. There is a McDonalds nearby that has only a 1.5 Mbps connection and kicks you off every 2 hours (although you can log on again and continue). While free, fast WiFi would be great, the problem that the institutions (like coffee shops and McDonalds and bookstores) have is one of profitability. Now, most people don't sit for hours (unless you count the laptop loungers at Starbucks), but those that do can cost businesses money. Then you have the fucking morons that roll in complete desktops (like they did at a Starbucks near me - complete with a laser printer that he covered the only handicap accessible table with) and actually LEAVE THE STORE FOR HOURS!! Look, businesses want people to come in, buy stuff and get out. If you want unlimited WiFi (though certainly not free) I would recommend getting a Clear account ($50 a month for unlimited internet the last time I checked).
How Can I Find Out How Much Bandwidth I’m Using at Home? I do illegitimate downloads, Netflix high quality daily, gaming and tons of legit file transfers and haven't come close to hitting Cox's cap of 200gb yet. Can't tell if you're trolling or not, so I'll give you the benefit of the doubt... 1. There are other applications that may be data-intensive that aren't illicit. 2. 3. 4. It's only common sense that you keep track of your usage if you have a plan that will charge you for overages or cut your access off... Use a streaming game service like Onlive and you'll be eating 2-3gb per HOUR. 250gb is nothing for a gamer. Maybe you should use some of that bandwidth to look up how to use their, there, and they're correctly.
Put Together a Home Networking Emergency Kit for When Your Router Kicks the Bucket Related security tip: if your router is failing but not completely dead yet make sure that you don't forget to wipe your old router before you toss it in the bin. This is obviously needed if you, for the sake of convenience, commit the "sin" of re-using your old router's SSID & wifi password... ;) See, if you haven't password protected the admin interface of your old router (way too many users don't bother changing the default admin login) it would be a trivial matter for your average nefarious dumpster diving neighbor to grab the failing router, log in using default admin credentials and retrieve the stored wifi password. Especially since many router admin interfaces will happily display the current WPA/WPA2 key in clear text once you are logged in. (Ugh.) Or you could, of course, choose a new password for your new router... :)
Bandwidth, and how to use it up The first thought that goes through the mind of all right-thinking people when they get a broadband Internet connection is "How can I use all of this bandwidth, all day long?" People who are still stuck with dial-up modem Internet access care deeply about bandwidth, too, for much the same reason that drowning people care deeply about air. So how can broadband users stretch the limits of their high-speed link, and what's meanest to a modem? Read on. Up versus down When someone talks about a communications link with a given bandwidth - say, 128 kilobits per second - they're usually referring to a half duplex connection at that speed. Note, here, that people often confuse bits and bytes when they're talking about connection speeds. There are a thousand bits in a kilobit, and a million bits in a megabit. So a 128 kilobit per second connection moves 16000 bytes per second, but that's only 15.625 kilobytes. And now, back to duplex. A humble modem link is, at least, full duplex. Web browsing Games
