How to Prevent Someone From Looking at Your Phone’s Other Pictures When You Show Them One

This has happened to all of us –  you hand your smartphone to someone else to show them a picture, and they will eventually start swiping left and right through the gallery. There is really no way to prevent this. Once you hand over your phone, unlocked, to someone else, they can do pretty much anything they want.

8 Things I Found on The Internet This Week Vol. 2

1. You’re Getting Old! is a fascinating website that offers a long list of facts and statistics relating to a person’s lifetime once they enter their date of birth. You get stats like the total number of times the person’s heart has beaten and the number of breathes they have taken in their lifetime, as well as how old they were when some important events occurred. The website also includes a pie chart featuring an approximation of how many people born on that date are currently alive versus dead as well as many more features. The older you are, the more fascinating the stats become.

How to Increase the Audio Volume of a Video File

Ever downloaded a video from the internet that is barely audible? Fixing the audio volume is a simple matter of demuxing the video file into its constituting video and audio channels, adding a constant gain to the audio channel and then packing both together into a video container. This tutorial will show you how to do that.

Years ago, I wrote a similar tutorial showing readers how to increase the volume of the audio channel of a video file using a software called VirtualDub. The method described worked only with AVI files. The new method that I’m going to describe in this tutorial works with common video formats such as MP4, MKV and AVI.

8 Things I Found on The Internet This Week Vol.1

1. Drowning Simulator: This is an interactive life jacket-awareness website that lets you “experience” drowning. The French website puts you in the shoes of a dude who gets knocked out of the yacht and into the sea. Once you’re in the water, you have to use your mouse to scroll without stopping in order to stay afloat. Eventually, when your finger starts to ache and your scrolling slows down or stops, you sink and die. The game ends with a simple message: “At sea, you tire faster than you think. Whenever you go out to sea, wear your life jacket.”

How to Combine Multiple Internet Connections to Increase Download Speed

Most people have access to more than one internet connection. There may be a cable Ethernet connection at home, a community Wi-Fi, and multiple 3G/4G connections via as many cell phones. Despite having so many different connection possibilities, you can only connect through one at a time on your computer.

Dispatch-proxy is a free and open source tool that essentially combines multiple internet connections into one single pipe. You can combine as many Wi-Fi networks, wired Ethernet connection, 3G or 4G connections you have access to, to one big load balanced connection.

Use Google Streetview to See What Cities Around The World Look Like Flooded

As global weather changes and the earth’s ice cap melts, the rising sea level is going to dramatically change the planet’s geography in the coming century. In order to raise awareness among the public about the disastrous consequences of climate change, a crowdfunded organization called CarbonStory, who focuses on various environmental projects, has teamed up with two marketing agencies to come up with an interactive website called World Under Water, ahead of the upcoming World Environment Day on June 5. Powered by Google Maps, the site lets you pick any Street View location and see what it will look like after sea levels have risen.

PDF Eraser: Edit, Remove or Add Text and Images to PDF Files

Most PDF editing tools are commercial, but PDF Eraser is not. While not exactly a software to edit PDF files in the traditional sense, the freeware program PDF Eraser does contain tools that allow you to remove objects and text from a PDF document, and add your own. Additionally, PDF Eraser allows you to rotate and delete pages from a PDF document.

GifCam: Record Screen, Edit, Annotate and Convert Into Animated GIF

Sometimes it’s more convenient to record the screen and share it in the form of animated GIF files rather than as videos. I do this when I want to show an action or the result of an action which cannot be properly conveyed through static pictures. On the other hand, videos are a hassle because they need to be uploaded to YouTube or a similar platform and require Flash to playback in the browser. Besides, GIF is more practical for screen recording that contains large areas that doesn’t change between frames. Additionally, GIF is better optimized for images that contain flat blocks of colors such as text, logos and illustrations (which is usually the case when recording a screen).

How to Make Gmail Show More Than 20 Results Per Page When Searching

By default, Gmail displays only 20 results per page when you perform a search. This figure is not configurable by any means through Gmail’s settings page. If you would like to increase the number of results returned, all you have to do is change a simple parameter in the URL. There is even a bookmarklet to help you do that.
