First time git config
The first thing you should do when you install Git is to set your user name and email address. This is important because every Git commit uses this information, and it’s immutably baked into the commits you start creating:
$git config --global user.name"Pascal E Fares"$git config --global user.email forgit@cofares.net
You need to do this only once if you pass the
--global option, because then Git will always use that information for anything you do on that system. If you want to override this with a different name or email address for specific projects, you can run the command without the --global option when you’re in that project.mercredi 30 mars 2016
Testing to Start for Computer With Chips Inspired by the Human Brain
The Wall Street Journal (03/28/16) Robert McMillan
The Lawrence Livermore National Laboratory (LLNL) on Thursday will begin testing a $1-million computer packed with 16 IBM TrueNorth microprocessors designed to mimic the functions of the human brain. Bundled into each TrueNorth chip are 5.4 billion transistors comprising a network of 1 million simulated neurons connected by a massive web of synapses. "TrueNorth is useful for deep-learning applications and for a broader class of machine-learning applications as well," says LLNL researcher Brian Van Essen. TrueNorth emulates the brain's low power consumption, with the 16 chips using only 2.5 watts together versus a typical server chip's power requirements of up to 150 watts. Van Essen's team will test TrueNorth by uploading some supercomputing tasks to it. Van Essen expects the system to help the lab filter out potential glitches in simulations of phenomena such as subatomic particle interactions and identify patterns in cybersecurity and video surveillance. "It's great that they're [testing TrueNorth]," says University of Washington professor Luis Ceze. "It's very efficient, but they have to show that the accuracy of the models that they implement [is] good enough."

Object-Oriented Meets Functional (SCALA)
Have the best of both worlds. Construct elegant class hierarchies for maximum code reuse and extensibility, implement their behavior using higher-order functions. Or anything in-between.
