What a completely brilliant performance by Julia R! She practically wipes the floor of the other weird person with the bodily spams. And what in earth was the meaning with "we don't need any harmonization"? What's the point of the common market to begin with if we don't harmonize the laws that exists in the common market?

Don't drink coffee and sleep. This is probably true if all that counts is to efficiently form longterm memory. However, I have a strong feeling the ability to enter a "flow" in your work and mind really matters too.
 
Why All Nighters Don't Work

Want to ace that test tomorrow? Here’s a tip: Put down the coffee and hit the sack.

The research is in eLife. (full open access paywall)

Research: "A single pair of neurons links sleep to memory consolidation in Drosophila melanogaster" by Paula R Haynes, Bethany L Christmann, and Leslie C Griffith in eLife doi:10.7554/eLife.03868 (http://elifesciences.org/content/elife/early/2015/01/07/eLife.03868.full.pdf)

Image: Memory consolidators inhibit wakefulness as they start converting short to long term memory. This takes place in the mushroom body. This image is for illustrative purposes only and the caption reads "Mushroom bodies visible in a Drosophila brain as two stalks". Image credit Jenett A, Schindelin JE, Heisenberg M/BioMed Central.

I think the immaterial pirate issue is a fascinating topic! A living, thriving culture encourage sharing and copying. It's through copying we learn new stuff. Society should embrace copying. At the same time we should embrace the idea that sharing your resources enables other people to do good things. For example, if you enjoy some good entertainment - share your resources and (for example) /pay/ for the experience! Otherwise you might not get a new experience unless you make a movie yourself.
Of course it goes deeper than just entertainment. If you can't prevent people from having private conversations, how can you  protect yourself against people copying your ideas and content? Forbidding /private/ file sharing, on the other hand, is ultimately a totalitarian idea.
Sharing computer code (as oppose to just sharing the data) has caused an explosion in out ability to automate workflows and produce new interesting content. For example, the Android OS is a Linux derivative which is all open source. Most of the algorithms controlling the Internet routers and protocols are open source. The potential in sharing ideas has been proven to be very, very powerful.

To get further in understanding the challenges (because the copyright- and patent wars are far from over) we need to introduce some nomenclature and differentiate between the (1) private spheres, which isn't regulated and where the strong rule, (2) the common market, which is where capital rule and economical transactions are heavily regulated and (3) the public space, which is work funded by the tax money and violence monopoly.

We can easily agree that on the /common market/, we should abide to a certain level of transparency and then of course, content control might even be important. It should apply to all transactions not only movies, but drugs, medical equipment, food we eat etc. (Enron, GMO, sex and guns). In the private sphere's we should only allow for the government to interfere if it can prevent violence or death.
 
"How should the artists get paid if we allow for private file sharing"? The answer is that enough people will pay for things they crave. There's a different side to this though just recently is starting to grow on us: "How is anyone getting paid in the near future when computers can do almost anything better than humans?" For sure, the question has been echoed every time we've seen technological change, but this time it isn't our muscles which are being replaced but our brains and this is different. So while some pirates might laugh at some content makers feeling ripped off, the real issue that working for money is going out of fashion. Real welfare and enablement comes from the access to cheap energy and the ability to process that energy into efficient automation by eliminating unnecessary work (which ultimately might be all work). What's left is to find a new system for distributing the wealth of the world. Understanding the nature of sharing what you care for to they people you care for might become really important then. In a sense, it has already begun, and when politicians are asked to "create jobs" this is what they attempt to do although they might be tricking themselves to believe otherwise.

Knowing what challenges the future hold and what will be required for building a better world is really hard. Copying and sharing really helps in finding the answers (even machinima ETC is making a better more communicative world, more true to itself, others and consequent in its intentions by sharing this show)

Copy and share.

I don't quite understand this clip.

How about: "Oracle is helping your economy by providing means to efficiently increase the availability to data, and eliminating unnecessary jobs. We call this help 'cloud computing', but its really a set of highly intelligent components which come together just as an orchestra.
The data is either structured measurements like log files, traffic graphs, social graphs and physical product attributes. Or it can be unstructured data yet to be understood or classified, found in blogs texts, user comments, emails, social or product interaction.
Every talented orchestra needs a conductor. Oracle brings your enterprise together and makes you the conductor with the control over harmony and intensity.
Imagine how your hiring program harmonize with the data from Facebook, LinkedIn or other social media sites. How leads are collected from search engines, and how form and inspiration from your designers automatically shape your production lines. This is the future we're offering now.
"
Let's hope the clip was cut in an unfavorable way. Oracle's a great company with a vast amount of talent and ambition. Why doesn't it show in this presentation? :-(

+8sl2k1 Maybe drugs would be cheaper if competitors more easily could copy previous discoveries and processes. The demand for drugs won't go away regardless on how quickly we develop them. The patent argument is only there to create resistance for government regulation on how a drug can enter the market. Possibly the process is too rigid or the cost should be shared by the governments.

A self-driving car using a Jetson TK1 dev board, Ubuntu Linux and just a single stereo camera!

PS:  Trust me that no company is going to ever sell driver-less cars for normal roads that only have a single camera to drive it, because for normal roads you need lots more sensors to look for pedestrians & bicycles & other cars around you! So a single camera is only useful for driving on empty roads when you know there's no risk of killing someone on the road. For normal roads, you need lots of other sensors (usually very expensive radars & ultrasonic sensors). eg: "http://www.vortez.net/news_file/4486_nvidia%20ces%202014%20press%20event%20tegra%20for%20adas.jpg". But atleast this car is able to do the actual driving with just one camera, even if it would need more cameras or sensors to look for obstacles & signs. Additional cameras around the car will potentially start providing much cheaper alternatives to these other expensive sensors.
