Generally, when you try to open a web directory in your browser, the browser will either return you an “index” page – an HTML page (or PHP or ASP etc.) that’s in the root of the directory, or if the index file is absent, it will deny access to the directory. But if the index file is missing and the webmaster forgot to password protect the folder, the server will return a listing of the files that are within the directory. An unprotected web directory is like a publicly accessible open computer. You can navigate within the folders, view files or even download them. Many webmasters routinely forget to configure their webservers to deny directory access, thereby exposing their content on the internet for anybody to see.

There are thousands of book stores on the internet that will sell you used books for cheap. If their business is in the same country as yours, you can even avail free shipping, or at least, a reasonable shipping rate. Book lovers from the United States and the United Kingdom are typically at advantage here because a large of number of publishing houses and book stores operate from these countries. But for international addresses, the cost of shipping is usually high enough to prohibit buyers from taking advantage of their services.

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.

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.

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.

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.”

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.

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.

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.
