3 Dangers Of Logging On To Public Wi-Fi

3 Dangers Of Logging On To Public Wi-Fi
You’ve heard that you shouldn’t open PayPal, your bank account and possibly even your email while using public WiFi. But what are the actual risks?
Well, your home WiFi is (hopefully) encrypted; the WiFi at the coffee shop isn’t. This means you’re at risk of people monitoring your online activity, or worse – unless you know how to protect yourself. Here are a few dangers, and how to avoid them.

Unencrypted Browsing Is Public

WiFi uses radio waves, and radio waves are anything but direct. They broadcast, and this means that anyone within range can see everything you’re doing online, if they have the right software.
This means that, without protection, anyone who wants to can see:
  • Every site you visit
  • Every bit of text you send out
  • Your login information for various sites
The danger here is clear, so naturally you’re going to want protection. At home, you can encrypt your WiFi network – this prevents snooping by making all of your traffic unreadable with a key. Public WiFi, however, usually isn’t encrypted – you can tell this is the case when you don’t need to type a password in order to connect.
Does this mean you’re defenceless? No.

Your first line of defence is OpenSSL, a kind of encryption offered by many websites: Google, Facebook and most banks, to name a few. This technology encrypts the traffic between you and another site, meaning no one will be able to snoop on that activity. You’ll know OpenSSL is on when you see “HTTPS” in your browser’s address bar, like this:

Build Your Own Awesome Personal 3D Avatar with Avatara

Do you use social networks and want to build your own awesome 3D avatar? Maybe you want to send someone a cute cuddly image of yourself (kind of)? Or maybe you have your own ideas of what you would do with an Avatar… Well look no further than Avatara which I discovered from the MakeUseOf directory . You can create 3d avatars out of pre-set up templates or create your own from scratch. To start, visit Avatara’s homepage . You will see this screen: Click Get Started to umm, get started! That will take you to this screen: You see that you can build your own Avatar using an uploaded head shot like the Obama one above (just an example, guys). Or roll with one of their awesome avatars. I chose to start with a blank avatar by clicking Start with a blank avatar at the bottom of the screen. That takes you to here: I clicked on the filter at the top and told it to filter out everything but male characters and then I saw this: I rolled with Buck and continued. You need to click Select...

MoviePass drops pricing to under $7 per month, if you opt for the annual plan

MoviePass, the subscription service that lets consumers pay a monthly fee to see unlimited movies in theaters across the U.S., is slashing its prices yet again. The company announced today it’s now offering its service for $6.95 per month, down from the current price of $9.95 per month, when customers commit to a one-year subscription plan. That works out to a flat fee of $89.95 annually. The deal is a limited-time promotion, as opposed to a permanent pricing change, but MoviePass didn’t say how long the offer is valid. However, it is open to both new and existing subscribers – the latter who would receive a 25 percent savings on their current subscription if switching over to the annual plan. This is not the first time that MoviePass has dropped its pricing. When the company introduced its $9.95 per month, one-movie-per-day plan this August, down from $15 for 2 movies per month (or more in select markets like L.A. and NYC, and going as high as $50), it saw so many new sign-up...
