This might sound completely obvious to some, but if you’re upgrading a perfectly functional electronic device, put all the electric adapters and cables in a gallon size Ziploc bag immediately after taking it apart.

For example, you might have a perfectly good 802.11n router that you’ve decided to replace with a brand-new 802.11ac router. Maybe you want faster wireless speeds from 802.11ac, or maybe 802.11ac will provide better range and speed with your home’s construction. Whatever the reason, you still have a router that works, you just want something better. So when you set up the new router, put the old router in a large Ziploc bag along with its power brick and any cable(s).

The reason I mention this is because I’m often amazed by how many people have a big box of adapters and cables, and in most cases have no idea which adapter goes with which device. I suppose they’re used to the “old days”, when companies actually went to the trouble to put their logos on things like power bricks. Nowadays, this is somewhat rare. Of the last two routers I owned, one had the name of the adapter’s manufacturer on it, while the other one had no manufacturer name at all, just the legally-required electrical info. And the power brick for my Dell netbook is actually branded by LiteOn.

There’s another benefit to doing this if you are your family’s “IT Guy”. Having a router or switch ready to go in a plastic bag means you can just “grab it and go” if there’s some kind of IT emergency that needs your help. More than once I’ve had to reach in my closet and get my trusty old Linksys WRT54GL to help a neighbor or family member diagnose a connectivity issue!

Have you ever wanted to convert a video file to an audio file? Like, maybe you wanted a small clip from TV show to use as a ringtone, or maybe your favorite band was on Conan or Kimmel and you wanted an audio version of their performance for your iPod or smartphone?

There are dozens of apps out there that claim to do that, but most of those websites seem scammy, as if the download is malware or the ads might infect your computer with some kind of virus. And even the legit apps often have some kind of toolbar or search engine they want to install.

But did you know that VLC, the malware-free Swiss Army knife of video players, can also convert video to audio?

Just open VLC and choose “Media” > “Convert/Save”:

In the window that appears, click “Add” and choose the video file(s) you want to convert:

Next, click the down arrow on the “Convert/Save” button and choose “Convert”:

On the next window, make sure the “Convert” radio button is selected, then choose the type of audio file you wish to create: OGG, MP3, MP4, FLAC or CD (WAV):

Choose an output destination, then press “Start”. VLC will appear to play the file: the main VLC window will appear, and the progress bar will move as if the video is playing at high speed, but no video will be displayed. When it reaches the end of the video, the conversion will be complete. You can then edit the audio in Adobe Audition (spendy, but awesome) or Audacity (free, but not as good as Audition).

By default, VLC will convert the audio to a 128kbps mp3. This is fine for things like ringtones.

If you’d like to convert at higher quality, select “Audio – MP3” at the previous step and then click the Options icon (the icon with the screwdriver and wrench). Click the “Audio Codec” tab:

Here you can adjust the bitrate as necessary. However, note that increasing the bitrate will not improve the converted file if the new file’s bitrate exceeds the original file. For instance, if the audio in the original file is 192kbps, editing the bitrate to 320kbps won’t make it sound any better; it’ll just make a larger file. You could, however, change VLC’s default bitrate from the 128kbps to 192kbps to get the best quality from the converted file.
