4 different ways to build a USB

4 different ways to build a USB

USB sticks are known and used by all, allow us to store large amounts of data, are easy to transport and they are getting smaller and economic. But with the growing popularity of services cloud storage many we have left in oblivion, however, these small devices are so versatile that we can give them different uses beyond simple storage.

1. Lock your computer

We use an old USB memory as “lock” to prevent unauthorized access to your computer through an interesting application called Predator , whose operation is incredibly simple.

  • You turn on your computer and insert the USB memory.
  • You start the application Predator. Although it is best to start automatically when you start the operating system
  • You begin to work normally.
  • If you’ll be away from your PC for a while, simply remove the memory port. This will lock the keyboard, mouse and screen.
  • To unlock the computer you just have to re-insert the device into the respective port.

The application has a totally free personal version you can download from their website .

2. Save profiles of Wi-Fi

Windows offers an option to save the profiles containing the settings of our Wi-Fi networks in a USB memory supported either for them or to facilitate the process of sharing access when a new computer joins the network.

When you copy the profile to a USB connection and share it, the other user need only insert the device into your computer and run the file that Windows has created. This will make the new profile appears in our list of available networks without the need for a search, since the profile includes the SSID of the network, such as your password. This method also works to quickly configure a connection on an Xbox 360 that we want to include in the network, for this we must select the “Windows Connect Now” in the options of Wi-Fi console.

To add a Wi-Fi in a USB memory simply right click on the icon of the connection you want to share (by selecting it from the list of connections in the Windows taskbar), and then click “Properties” . In the new window that opens go to the tab “Connection” and in this, click on the “Copy this network profile to a USB flash drive.”

Personally I find this method useful to connect to networks that are configured to not broadcast its SSID through broadcast.

3. Speed up computer

The latest versions of Windows include an interesting feature called ReadyBoost, which allows us to increase the speed of your computer by simply connecting a USB memory. Enabling this feature Windows uses the available space on the flash drive as a cache for the applications that are running. This, thanks to which, in some cases, Windows can read USB memory much faster than the hard drive itself.

The increase in speed is amazing, especially if the hard drive of your computer is running at 5400 rpm or less. The change is not noticeable whether your hard drive is 7200 rpm. On the other hand, if you’re lucky and you have a SSD, ReadyBoost forget, because Windows will not even show the option, of course, because these drives are much faster.

If you have a USB memory quickly enough and with at least 256 MB of free space, simply insert it into your computer, right click on its icon in the device list and choose the option to activate ReadyBoost, respective tab within the properties.

4. Set up a portable web server

Days ago, our colleague Barbara shared with us a list of useful and interesting portable applications , but beyond these I would like to share with you one that will be especially useful for web developers.

The application in question has the name Server2Go . This small utility allows us to carry with us a complete fully functional WAMP server for free, so we can carry our projects and demonstrate everywhere even if we do not have Internet access or need to work on a computer that does not have WAMP server installed.
