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).

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.

Wikipedia is a massive time sink. It so captivates you that you never know how long it takes once you start reading. You may look up something as simple as “duck” and hours later find yourself reading about agricultural practices of Ancient Mesopotamia. The chase down the rabbit hole of hyperlinks can be interesting, exhausting and at times really troubling, especially when you have serious work to do. Who knows how many millions of hours are collectively “wasted” each day by readers absorbed in cross referencing?

One of the reasons why people prefer an SLR camera over compact cameras or camera phones, aside from the image quality, is that an SLR camera allows you to take photos with a shallow Depth of Field. Shallow depth of field makes the object of interest "pop" by bringing the foreground into focus and de-emphasizing the background. Achieving this optical effect traditionally requires a big lens and aperture, and therefore hasn’t been possible using the camera on your phone, at least, optically.

Back during the days of Geocities, no website would be complete without a healthy dose of 256-color animated GIF images thrown in wherever possible. Twenty years later, GIF images haven’t aged a bit. Now more mature (and sometimes not), they still rule the internet in one form or the other whether they be providing demonstration of complex machinery, or showcasing something beautiful or posting awful memes.

It has been argued, and quite successfully, that piracy can be fought back by making content readily available to paying customers. Services such as Netflix, Amazon Instant Video and Hulu are based on this very model and appears to be largely successful, both in business and in cutting down piracy so much that BitTorrent traffic has been reduced in North America to only 7.4% from 31% five years ago, while Netflix now accounts for nearly one-third of total internet traffic in the continent. This is all great if you live in the U.S. But what if you don’t?

There are typically three ways to share or post images on blogs, discussion boards and social media sites – 1) embed the full image with or without the image URL, 2) embed a thumbnail sized image with a clickable link to the original image or 3) post only the URL of the image, clickable or not. Each one has its merits and demerits.

Nothing To Hide is an anti-stealth game that carries a not too subtle message. The protagonist is a teenage girl named Poppy, who lives with her father in a world constantly under government surveillance. Poppy must sneak out of the house and across the city but without alerting the government's numerous surveillance tools. While a typical stealth game requires the player to stay out of enemy’s sight and security cameras, Nothing To Hide, being an anti-stealth game, requires Poppy to stay in sight of the cameras at all times. Wandering outside their view for longer than a few seconds gets her killed and she has to start again.
The default Windows calculator is a decent program that, aside from basic math, can perform binary and hexadecimal calculations, Boolean arithmetic, handle trigonometric and logarithmic functions, and perform statistical analysis. It can also convert measurement units, calculate calendar dates, and figure out your mortgage, vehicle lease and fuel economy. It’s an all-round multipurpose calculator that should be enough for most people. You can still pick at it, if you want to. For instance, you can argue that there is no way to save history or a session. After trying out several different calculators, I rounded up three programs that in my opinion, are a tad better than the default Windows calculator.

American space agency NASA in collaboration with non-profit Saylor Foundation is offering a new massive open online course or MOOC on “Space Systems Engineering” starting March 3, 2014. The six-week, general-audience course is available to the public at no cost and provides a unique opportunity to learn from and alongside NASA's engineers. Students who participate will also earn a free certificate.
