Submission + - With TensorFlow, Google open sources its machine learning resources (networkworld.com)

smaxp writes: Deep learning, machine learning, and artificial intelligence are all some of Google's core competencies, where the company leads Apple and Microsoft. If successful, Google's strategy is to maintain this lead by putting its technology out in the open to improve it based on large-scale adoption and code contributions from the community at large.

Festo's Drone Dragonfly Takes To the Air 45

yyzmcleod writes "Building on the work of last year's bionic creation, the Smart Bird, Festo announced that it will literally launch its latest creation, the BionicOpter, at Hannover Messe in April. With a wingspan of 63 cm and weighing in at 175 grams, the robotic dragonfly mimics all forms of flight as its natural counterpart, including hover, glide and maneuvering in all directions. This is made possible, the company says, by the BionicOpter's ability to move each of its four wings independently, as well as control their amplitude, frequency and angle of attack. Including its actuated head and body, the robot exhibits 13 degrees of freedom, which allows it to rapidly accelerate, decelerate, turn and fly backwards."

Emscripten and New Javascript Engine Bring Unreal Engine To Firefox 124

MojoKid writes "There's no doubt that gaming on the Web has improved dramatically in recent years, but Mozilla believes it has developed new technology that will deliver a big leap in what browser-based gaming can become. The company developed a highly-optimized version of Javascript that's designed to 'supercharge' a game's code to deliver near-native performance. And now that innovation has enabled Mozilla to bring Epic's Unreal Engine 3 to the browser. As a sort of proof of concept, Mozilla debuted this BananaBread game demo that was built using WebGL, Emscripten, and the new JavaScript version called 'asm.js.' Mozilla says that it's working with the likes of EA, Disney, and ZeptoLab to optimize games for the mobile Web, as well." Emscripten was previously used to port Doom to the browser.

Google took its biggest leap yet onto Facebook’s turf on Tuesday, introducing a social networking service called the Google+ project — which happens to look very much like Facebook.

Do people really use Google and Facebook for the same things?

Submission + - Homemade iSCSI SAN (geeks-4-jesus.org)

bamed writes: "There's been so much talk about SAN's lately, and I knew my budget would never allow me to purchase one, so this week I built my very own iSCSI SAN.

I put together a system with an AMD Athlon64 X2 AM2 3800+ with 2GB DDR2 800 RAM, a 20GB IDE HDD for the OS and 4 250GB HDD I had lying around. Three of the 250GB HDD's are IDE and the fourth is SATA. When my budget allows I intent to replace the IDE's for SATA's. I installed Ubuntu Server 7.04 on the 20GB HDD. Then installed iscsi-target, configured my LUN's and all was done. For the moment I'm just using one of the 250GB HDD's as a backup for our server, but now that I know how easy it was to setup, I'm going to think of some more creative ways to use my homemade SAN.

For those of you interested, here's how I setup the software.

First download and install Ubuntu. It was pretty straightforward so I won't get into that part of it. Once Ubuntu is installed get all the updates, including any kernel updates:

# sudo apt-get update
# sudo apt-get dist-upgrade
# sudo apt-get upgrade
Once all the updates are installed reboot. Now you need to install a few more packages:

# sudo apt-get install make
# sudo apt-get install libssl-dev
# sudo apt-get install linux-headers-`uname -r`
# sudo apt-get install gcc
Now make a symlink to your kernel source:

# sudo ln -s /usr/src/linux-headers-`uname -r` /usr/src/linux

This way make can find your kernel source files when you compile scsi-target without any other configuration from you.

Now download iscsi-target from http://sourceforge.net/project/showfiles.php?group _id=108475. Unzip and untar the file, the cd into the directory you extracted it to. Now:

# make
# sudo make install

If you don't get any errors iscsi-target is installed. I did find one compatibility problem with the startup script with Ubuntu. To fix it edit /etc/init.d/iscsi-target by changing the first line from

#!/bin/sh

to

#!/bin/bash

No copy the ietd.conf file from the etc/ directory under the directory where you compiled iscsi-target to the systems /etc directory. You should read the man files and all associated documentation, but the only things you need to worry about to get up and running are the 'Target', 'Lun 0 Path=', and 'Alias' options. Configure these according to your system, then start up iscsi-target:

# sudo /etc/init.d/iscsi-target start

Now you just need to configure your iscsi initiators on whatever your want to use the iscsi drives on. I tested it in Windows and in Linux and it works beautifully. So far I've only tested it by making one HDD = one LUN, but it should be able to support different types of configurations such as RAID or file LUN's, and there's failover support as well. I'll look into these some more and get the details back to you.

I'm just excited to have a 1TB homemade SAN to play with now."

Submission + - Bringing Back Geography to the U.S.

An anonymous reader writes: Here is are 2 articles on history of geography and the state of geography education in the U.S. From the article: "Soon after World War II, however, geography was purged in the United States, and the impact continues today. From 1948 to 1988, the discipline was expunged at the University of Chicago, Columbia, Harvard, the University of Michigan, Northwestern, Stanford, Yale, and other esteemed American universities, oddly even during periods when universities were expanding faster than at any other time before or since. In truth, nobody knows why geography was targeted on such a broad scale." See also related stories below.
