T he humble 404 has been with us since the tubes that make up the internet were first plumbed in. Websites can actually return a whole smorgasboard of different error codes, but 404 is the most common and generally referred to as “ not found “. Unfortunately, the default message is pretty much as unhelpful as you can get, so today I’m going to show you how to tweak your  WordPress 404 error page  to be a whole lot more useful. DIY or Friendly 404 Messages You may have noticed we have our own  custom error page at MakeUseOf  which is somewhat more welcoming than the default message. To make your own custom error page, simply create a template called  404.php  in your theme folder – if you don’t already have one that is. Duplicate the single page template if you like, and cut out the main content area. You can then either hand code an image like we have, or write your own simple message.

  S ometimes it may seem safer to go back to the days of the Pony Express rather than deal with the multitude of online threats, but there are some simple steps you can take to minimize the risks you face.

Go with one that gets good ratings and that you trust, and make sure that you let it update and scan regularly.

But third-party managers allow you more options, such as mobile device support, that I find essential. LastPass (download) and RoboForm (download) are among the best cross-platform tools out there that will work on both Windows and Mac and have smartphone support. Third, use two browsers. Do your mission-critical browsing, such as financial transactions, in a separate browser from your...

Until recently, creating your own Chrome theme meant you either had to know some code, or you had to rely on a Web app . Google recently released a Chrome app called My Chrome Theme , that makes creating and sharing themes extremely easy and a lot of fun. The app breaks down the theme creation process into three steps: Import your image: Upload an image or take a photo with your webcam. Add some color: Select colors for the toolbar, background, background tab, and frame. Install & share: Install the new theme and share the unique URL with others. The next time you launch My Chrome Theme, thumbnails for your themes will appear in a list at the bottom of your browser. Clicking on them will allow you to install, delete, or share them. That's it. Keep in mind that the size limit for photos is 5MB and that you should only upload photos you have rights to use. Images from completed themes are stored on Google's servers. source: Here
