World Photo Day is an international photography event on August 19th that celebrates the passion for photography in our communities.
In a world where millions of pictures are uploaded every minute, World Photo Day is inspiring thousands of photographers across the planet to share a single photo with a simple purpose: to share their world with the world.

From everyday life to incredible landscapes, our global gallery is an evolving mosaic of images captured by photographers of all skills levels living in a diverse range of countries and cultures.

No matter who you are, where you are or what equipment and skills you have, World Photo Day can help open your eyes to the possibilities of photography, and enable you show us the world as you see it.

How did we decide when we should host World Photo Day?
The date behind World Photo Day originates from the invention of the Daguerreotype, a photographic processes developed by Joseph Nicèphore Nièpce and Louis Daguerre in 1837. On January 9, 1839, The French Academy of Sciences announced the daguerreotype process. A few months later, on August 19, 1839, the French government purchased the patent and announced the invention as a gift "Free to the World".

It should be noted that the Daguerreotype wasn't the first permanent photographic image. In 1826, Nicèphore Nièpce captured the earliest known permanent photograph known as 'View from the Window at Le Gras' using a process called Heliography.

August 19th, 1839 was chosen as the date behind World Photo Day based on the following historical merits:

- The Daguerreotype as the first practical photographic process.
- The purchase and release of the patent by the French government.

Turning an idea into a globally celebrated photography event

Every big project starts with an idea. Turning that idea into reality is almost always harder than it looks. The World Photo Day project started in 2009 and it was celebrated for the first time on August 19th, 2010. We've come along a long way since those early days and we're always working on new opportunities and ideas.

We started with a very amateur and simple first website. Our user registration system didn't work very well and we didn't have a password reset feature for our first 2 years. With help from good friends, World Photo Day Founder, Korske Ara spent hours of his spare time learning the skills needed to build a website that could support a global gallery.

Today, millions of people around the world are reached by our efforts to celebrate photography and thousands of photographers are getting involved through independent community events, competitions and promotions.

Become part of the World Photo Day story and share your world in our official World Photo Day gallery.

Facebook's solar-powered internet drone takes flight

Facebook Inc said on Thursday it had completed a successful test flight of a solar-powered drone that it hopes will help it extend internet connectivity to every corner of the planet.
Aquila, Facebook's lightweight, high-altitude aircraft, flew at a few thousand feet for 96 minutes in Yuma, Arizona, Chief Executive Mark Zuckerberg wrote in a post on his Facebook page. The company ultimately hopes to have a fleet of Aquilas that can fly for at least three months at a time at 60,000 feet (18,290 meters) and communicate with each other to deliver internet access.
Google parent Alphabet Inc has also poured money into delivering internet access to under served areas through Project Loon, which aims to use a network of high-altitude balloons to made the internet available to remote parts of the world.
Yael Maguire, Facebook's engineering director and head of its Connectivity Lab, said in an interview that the company initially hoped Aquila would fly for 30 minutes.
"We're thrilled about what happened with our first flight," Maguire said. "There are still a lot of technical challenges that need to be addressed for us to achieve the whole mission." He said he hoped the system might be brought into service "in the near future."
Zuckerberg laid out the company's biggest challenges in flying a fleet of Aquilas, including making the plane lighter so it can fly for longer periods, getting it to fly at 60,000 feet and creating communications networks that allow it to rapidly transfer data and accurately beam down lasers to provide internet connections.
Maguire said Aquila will go through several more test flights and hopes it will soon break the world record for the longest solar-powered unmanned aircraft flight, which currently stands at two weeks.
Facebook, which has more than 1.6 billion users, has invested billions of dollars in getting more people online, both through an initiative called - which offers a pared-down version of the internet to poor areas - and by building drones.

Meet Ultimate Boot CD, a tool every computer owner must have
Problems with a computer -- laptop or desktop -- are the worst kind of problems. At a time when they are in the middle of our digital lives, these issues can be even crippling and although modern computers are fairly hard to break, there are occasions when they fail. When you run into problems, here is what that can happen:
-- The computer won't switch on.
-- The computer will switch on but won't boot.
-- The computer will have BSOD (blue screen of death) and shutdown. Again and again.
These problem is on most occasions hardware related. If the computer won't even turn on, you have no option but go to a service centre. Or, if it is an assembled desktop and you are comfortable with computer hardware, you can open the box and look into the power supply issues.
But if the machine is facing the other two problems, you can troubleshoot it. And while trouble-shooting, one indispensable tool you need to have is the Ultimate Boot CD.
Here is a personal example. Recently, my computer, which was assembled around four years ago, started having BSODs. It just switched off and when I tried rebooting, most of the time the effort resulted in more BSODs. Even on occasions when I managed to log into the safe mode in Windows, it suffered BSOD within minutes.
There was clearly something wrong with the hardware of the computer because it wouldn't even let me go to the Windows recovery options.
So, how do you fix something like this? You need Ultimate Boot CD.
What is Ultimate Boot CD?
Ultimate Boot CD is a collection of tens of widely-used software tools. All these tools are free and are available as standalone programs. But Ultimate Boot CD brings them in one place. These tools can diagnose and benchmark computer hardware. They can even help you save your data when things go wrong.
Although the name says it's a CD, it is actually a file. It is an ISO file, the kind of files that CDs have. You can put this file onto a CD or (better) you can put it in a pen drive.
What it can do?
Ultimate Boot CD can help you diagnose problems with computer's hardware, including problems with RAM, CPU, hard disk and graphics card. The most serious kind of problems, which often result in BSODs, usually happen with these components. The Ultimate Boot CD can also help you access data in various hard drives in your computer, and if required, move them whenever possible. This means even if your computer is not booting, you can most likely save your precious data.
How to create Ultimate Boot CD?
As the name suggests, to diagnose problems with a computer you need to boot using the Ultimate Boot CD. Here is how to do it:
-- Download Ultimate Boot CD from here
-- Download Universal USB Installer from here…/
-- Once the two files have been downloaded, plug in a pen drive with at least 1GB capacity into the computer.
-- Open Universal USB Installer. Select Ultimate Boot CD from the list. Tell the program where the Ultimate Boot CD is located on your computer (navigate to path) and then follow instruction to create a bootable pen drive.
-- The pen drive with Ultimate Boot CD into it should be ready for use in a few minutes.
How to fix problems using Ultimate Boot CD
Once you have created the bootable pen drive, you can use it to fix issues. Ideally, you should keep one such pen drive handy. You never know when your computer has a problem. Also, once your machine has a problem and you don't have the Ultimate Boot CD pen drive, you will have to seek another computer on which you can create such pen drive.
To use the Ultimate Boot CD pen drive, plug it in the computer that has a problem before you turn it on. After turning it on, press the required key to get into the BIOS. Different laptops and computers use different key for BIOS. For example on my computer this key is DELETE key. This key has to be pressed before you see animated Windows logo.
Once you are successfully into the BIOS, look for the boot order and set the computer to boot from pen drive.
Once you have booted from the pen drive, here is what you will see:
You can navigate within this menu using ENTER, ARROW keys and ESC key. There are lots of tools here. Depending on the issue you are facing on your computer, you can use various tools. But in general two tools are important.
1- Most of the problems in computer happen because of failing RAM or dying hard disk.
2- To check RAM, use the Memtest86. If there are errors, the RAM in your computer is faulty. Even one error here is bad.
3- To check hard disk, use SeaTools. If there are errors with the hard disk, that is faulty.
In my case, the problem was with the RAM which showed errors at its specified speed of 1866MHz. But the same RAM passed the Memtest86 at a reduced speed of 1333MHz so I reduced the RAM speed in BIOS and managed to access all the data in the computer. It will probably fail again in future, even at reduced settings, but for now the computer is fine so I can live with it.
While troubleshooting is one aspect of the Ultimate Boot CD, you can also use it to check and stress test a new computer. There are lots of benchmarks built into the CD, which can be used to find faults, if any, in the hardware of a newly bought or assembled computer.
