Step aside, Facebook.

Step aside, Facebook. There’s a new social network in town. Scholarly versions of Facebook, designed specially for researchers, have taken off to a degree that no one expected. But what are researcher using these networks for? Do they offer anything that Facebook and Twitter don’t? And what does the trend mean for science? We surveyed thousands of academics to find out go.nature.com/fjvxxt

Stay beautiful!use sunscreen!

Videographer Thomas Leveritt asked people on the street to take a look at themselves under ultraviolet light, exposing sun damage beneath the skin that hasn’t revealed itself yet. But it’s when Leveritt offers his subjects sunscreen that we see the true effectiveness of that greasy stuff.

There is a book coming out about Joss Whedon. This is a good chapter about the beginnings of Firefly. Hopefully this hasn’t already been posted here.

Can we have distributed communications systems or not?

Originally shared by Will Hill

Can we have distributed communications systems or not?  A conversation on Diaspora has gone so wrong, that I suspect impersonation.  Edward Morbius continues to tell me that port blocks and other technical measures against people running mail servers are justified by the high volume of spam that large mail ops receive.  I think that leads to unacceptable spying and censorship and that the same reasoning will be used to dismantle any effective, distributed communications method.   If I can’t be trusted to run a mail server, why should I be trusted to run a Friendica pod?   Is this really Ed that I’m talking to?  

If anything the cost of spam to large providers proves that email and other services are better done small.  Small servers don’t have enough readers to be worth while.  Damage to one server impacts fewer people.  An abundance of choices gives everyone redundancy, and so on and so forth.  There is an analogous security argument for an abundance of free software distributions. Freedom leads to cooperation, abundance, diversity and security.  Centralization leads to monopoly, censorship and neutralization of dissidence.  I thought these were bedrock concepts of free computing and networking.  

Is there something I’ve missed here?

The Morse Code Virtual Radio is our new educational resource that lets you simulate the main form of radio communication that was used during World War I, using your Raspberry Pi.

You’ll learn how to send and decode Morse Code messages, and gain experience in Python programming and using the Raspberry Pi GPIO pins.
