The Future Is Here: Engineering Students Discover How To Use Wi-Fi to Charge Cell Phones | Tech-Picks | Scoop.it
In the future, cell phones will charge on air. We're almost there, thanks to the genius engineering students who figured out how to charge cell phones with a Wi-Fi signal.

Camilo Rivera's insight:

I can only guess that the next step would be to recover some of the energy spent by 3G/4G networks. It remains to be seen how efficient this material is. It will probably face some of the same challenges of solar panels, but still quite an accomplishment.

"In-memory Mnesia database using about 2TB of RAM sharded across 16 partitions to store about 18 billion records."

"Erlang love. Great language to support so many users with so few engineers"

"Asynchronicity to minimize impact of latency on throughput"

"Nodes are run in pairs. One is primary and the other secondary. If one or the other goes down they they will be handling primary and secondary traffic"

"Added a write-back cache so messages could be delivered before they had to be written to the filesystem. 98% cache hit rate"

This is a great article to introduce you to the Unicorn of Death. The UoD gets attention.


The UoD has nothing to do with the "Top 15 Most Used Cliche Images in Web Design", but if I used any of the images highlighted in the article you'd skip right past this post.


In good design there has to be something of value to put your attention in a chokehold, otherwise it's cheap decoration. Design cliché's are just that.


You can thank the folks who set the standards at microstock sites like iStock, Dreamstime et,al.


From experience, I've had images rejected because they were deemed "..not stock-worthy..." Considering the images that are stock-worthy, that's not such a bad thing.

Lectures Didn't Work in 1350—and They Still Don't Work Today

Lectures Didn't Work in 1350—and They Still Don't Work Today | Tech-Picks | Scoop.it

It’s all about engagement. I’ve heard things like a child’s attention span, in minutes, is equal to their age in years. That’s so not true. If children are engaged in something, they’ll spend hours on it. We have a 6-year-old grandchild who will spend hours working on Legos or Tinkertoys because she’s got something in her mind that she wants to build, and she’ll do it. If children aren’t paying attention, it’s not because of a decreased attention span—it’s because they aren’t given tasks that honor their dominant ways of learning.
