NOVA just released a interesting video on cyber security called Rise of the Hackers. Some part of the video is a little bit dramatic, but overall it is very informative and eye-opening. It did a good job on conveying the idea that the Internet is a very dangerous environment and the cyber security is a tug-o-war between defenders and hackers, and also did an excellent job on explaining how quantum computing works even though it […]
If you woke up tomorrow, and your Internet looked like this, what would you do? Imagine all your favorite websites taking forever to load, while you get annoying notifications from your ISP suggesting you switch to one of their approved “Fast Lane” sites. Think about what we would lose: all the weird, alternative, interesting, and enlightening stuff that makes the Internet so much cooler than mainstream Cable TV. What if the only news sites you […]
When Windows 8 was first introduced, the iconic Start menu was removed. Many users were frustrated by this removal. For instance, you cannot shut down your computer the same way you do in previous versions of Windows: Start->Shut down. You will need to switch to the home screen, then choose shut down from the power icon. Responding to users’ objection of the removal of the Start button, Microsoft sort of brought back the Start button in Windows […]
If you need to capture the home screen (with the live tile) of Windows 8.1 (or Windows 8) in a laptop or desktop computer, how do you do that? Of course, you can always use a camera to take a picture of the home screen, but the quality will not be impressive (give it a try if you don’t believe me). Below are two better yet simple ways to get a quality screen capture of Windows […]
You probably already heard that Sprint’s new CEO Marcelo Claure has three priorities to turn the company back on the right track: cut prices, improve the cellular network, and reduce the operation cost. To me, the first two should be done at the same time. I have been with Sprint since 2011 the then unlimited family plan (it is a grandfather plan now because Sprint has discontinued the plan) because my family is heavy on […]
Have you had the experience that when you were in a grocery store and realized you forgot to bring your shopping list with you? Well I had that experience many times, and that is why I am now using Google Keep to help me out whenever I go shopping. Google Keep is a notepad app developed by Google and it supports notes in audio, video, text format. All notes are stored on Google Drive and […]
Amazon released a new shipping option for Prime members called FREE No-Rush Shipping, which will automatically give the member $1 Amazon Instant Video credit if the member selects this shipping option instead of the FREE Two-Day Shipping. The credit is valid for 30 days after it is added to the member’s account. This is Amazon’s new approach to cover its shipping cost besides the last Prime membership cost increase. If you are a Prime member, […]
Recently I was trying to install an Ubuntu Server in VirtualBox, and I noticed that my host Windows OS is 64-bit, but VirtualBox does not have options for 64-bit guest OS in the Create Virtual Machine interface. My first thought was I need to install 64-bit VirtualBox, but I was wrong. There is only one version of VirtualBox for both 32-bit and 64-bit host PC. After some digging around, I realized that in order for VirtualBox […]
Two months after the initial announcement of shutting down Ubuntu One file syn service by Canonical, the Ubuntu One team sent out the second notice, maybe the last notice, to remind all Ubuntu One users to migrate their valuable data from Ubuntu One server to somewhere else by July 31st, 2014, which is the official last day of the Ubuntu One service. As previously announced, the file services for Ubuntu One have been discontinued. Your data […]
Convenience always comes with a price, and this is also true when you order your pizza online. I am not talking about the price you pay for your pizza; I am talking about the security you may sacrifice when you enjoy the convenience brought by the east online order service from any pizza store. Recently hackers claim that they have grabbed the passwords of about 65k customers from Domino’s Pizza in France and Belgium, and […]
