While digital books have made purchasing easier than ever, the medium has complications!
One Alabama library is demanding jail time for late books. How is this happening in a nation that's reading less and less?

Wow! (No me esperaba la de los barcos.)
Not what it seems despite the title!
And this is why we must never trust just one source, or first impressions. I remember this photo well, and I have to admit I too fell for the original opinion...
It is a failing of human nature to detest anything that young people do just because older people are not used to it or have trouble…

A great report from John Oliver on scientific studies, and how they are reported in the mainstream media. He is in fine form with everything from open science and replication studies to TED talks and morning shows

Richard Feynman's method for understanding science can also be used for detecting pseudoscience.

Fake "Real TV shows".

From the paranormal like: GHOST ADVENTURES
To the prosocial like: 8 MINUTES IN HELL
Even Bear Grylls or the PAWN STARS were a set up.
In many cases, reality TV is even more fake than you think. ?>
oh loco... hyper WTF?
Jump for joy

Dolphins do this.  Why?   Maybe just for fun.  If you've ever seen the amazing games they play with air bubbles, you'll know what I mean.  If you haven't, check this out:

It was one of my most popular posts!

But people actually debate this question.  Here's what they say at Dolphins-World :

Why do dolphins jump out of the water?

There is an ongoing debate about why dolphins jump out of the water.  Scientists think about different reasons for this behavior.

Among them, some think that dolphins jump while traveling to save energy as going through the air consume less energy than going through the water.

Some other think that jumping is to get a better view of distant things, mainly food. So, in this way, dolphins jump to locate food or food related activity like seagulls eating or pelicans hunting.

Other explanation suggest that dolphins use jumping to communicate either with a mate or with another pod.

Some people even think that dolphins jump for cleaning, trying to get rid of parasites while jumping.

Finally some scientists think that they are only having good fun, as playing helps to keep senses at their best.

The idea that this double flip "saves energy" is idiotic.   The other ideas are possible.  But I think it's likely that all sufficiently intelligent life forms do stuff "just for fun".  There are plenty of good biological reasons for this, I think.

For an average linux user, is it recommendable to install an antivirus and a firewall?

If affirmative which one do you use and why?

There is no reason NOT to run an AV. What can I say.. it's not IF but WHEN will somebody make a successful attack on Linux platforms. All platforms can be breached so too Linux.
The payload on your system is minimal, for the added security.
I use Sophos AV

There's nothing worse than wanting to expand your knowledge, satisfy your curiosity, or just confirm some weird historical fact, and getting blocked by a paywall or the sad reality that what you need is tucked away inside a book that you have to go...
