    The Architecture of Analytics: Big Time Big Data and Business Intelligence This four-session track, part of the free OTN Virtual Technology Summit on July 9, will present a solution architect's perspective on how business intelligence products in Oracle's Fusion Middleware family and beyond fit into an effective big data architecture, offering insight and expertise from Oracle ACE Directors and product team experts specializing in business Intelligence to help you meet your big data business intelligence challenges. Register now! Sessions Oracle Big Data Appliance Case Study: Using Big Data to Analyze Cancer-Genome Relationships Tom Plunkett, Lead Author of the Oracle Big Data Handbook What does it take to build an award winning Big Data solution? This presentation takes a deep technical dive into the use of the Oracle Big Data Appliance in a project for the National Cancer Institute's Frederick National Laboratory for Cancer Research. The Frederick National Laboratory and the Oracle team won several awards for analyzing relationships between genomes and cancer subtypes with big data, including the 2012 Government Big Data Solutions Award, the 2013 Excellence.Gov Finalist for Innovation, and the 2013 ComputerWorld Honors Laureate for Innovation. [30 mins] Getting Value from Big Data Variety Richard Tomlinson, Director, Product Management, Oracle Big data variety implies big data complexity. Performing analytics on diverse data typically involves mashing up structured, semi-structured and unstructured content. So how can we do this effectively to get real value? How do we relate diverse content so we can start to analyze it? This session looks at how we approach this tricky problem using Endeca Information Discovery. [30 mins] How To Leverage Your Investment In Oracle Business Intelligence Enterprise Edition Within a Big Data Architecture Oracle ACE Director Kevin McGinley More and more organizations are realizing the value Big Data technologies contribute to the return on investment in Analytics. But as an increasing variety of data types reside in different data stores, organizations are finding that a unified Analytics layer can help bridge the divide in modern data architectures. This session will examine how you can enable Oracle Business Intelligence Enterprise Edition (OBIEE) to play a role in a unified Analytics layer and the benefits and use cases for doing so. [30 mins] Oracle Data Integrator 12c As Your Big Data Data Integration Hub Oracle ACE Director Mark Rittman Oracle Data Integrator 12c (ODI12c), as well as being able to integrate and transform data from application and database data sources, also has the ability to load, transform and orchestrate data loads to and from Big Data sources. In this session, we'll look at ODI12c's ability to load data from Hadoop, Hive, NoSQL and file sources, transform that data using Hive and MapReduce processing across the Hadoop cluster, and then bulk-load that data into an Oracle Data Warehouse using Oracle Big Data Connectors. We will also look at how ODI12c enables ETL-offloading to a Hadoop cluster, with some tips and techniques on real-time capture into a Hadoop data reservoir and techniques and limitations when performing ETL on big data sources.

  • My Dog Ate My Surface

    - by Richard Jones
    Working for a Microsoft partner I was very fortunate enough to be given clearance to order a Microsoft Surface RT tablet. Justification, show new device to a customer event this Thursday. All good, time to develop an App. Surface arrived last Wednesday. Overnight, Coco our much loved one year old puppy Larba-Doodle pulled the power chord out of my bag and bit right through the cable (at the power-brick end). A quick re-order to Microsoft saved the day. Demo went great. Surface is fab, Coco; much loved too Laptop bag now placed a bit higher up in our house.

  • Grid based collision - How many cells?

    - by Fibericon
    The game I'm creating is a bullet hell game, so there can be quite a few objects on the screen at any given time. It probably maxes out at about 40 enemies and 200 or so bullets. That being said, I'm splitting up the playing field into a grid for my collision checking. Right now, it's only 8 cells. How many would be optimal? I'm worried that if I use too many, I'll be wasting CPU power. My main concern is processing power, to make the game run smoothly. RAM is not a big concern for me.

  • How do you deal with the details when reading code?

    - by upton
    After reading some projects, I find that it is not the architecture of the software that is really hard to know. It is not hard to figure out the architecture immediately if the project is clearly designed and implemented, if it's hard and never seen before, some day later I can find out some pattern similar to the one I read in the same domain. The difficulty is that the concepts and mechanism defined by the author are really hard to guess, and these concepts may spread in the whole project which makes it hard to grasp. The situation is normal and universal and you can ask questions to your colleague when in a company. However, it gets worse if nobody around you knows these details. How do you handle these details which block your reading?

  • How to fix slow wireless with Intel 4965 AGN? [closed]

    - by mikewhatever
    Possible Duplicate: Slow wireless with an Intel 4965 We run Ubuntu 12.04, 32bit, with the current kernel 3.2.27-generic on an MSI EX700. I've already added the 11n_disable=1 tweek, without whcih, wireless has been unusable. Now, it works OK, but speedtest shows: Windows XP - down 11.68mbps, up 2.07mbps Ubuntu 12.04 - down 2.06mbps up 2.0mbps We've disabled ipv6, tried static and dinamic IPs, tried both swcrypto=0 and swcrypto=1 options, none of whcih made any difference. The problem may be the symptom of high packet loss. For example, here's the output of iwconfig after booting and testing the speeds: wlan0 IEEE 802.11abg ESSID:"amu" Mode:Managed Frequency:2.462 GHz Access Point: 00:78:9E:FA:32:C8 Bit Rate=54 Mb/s Tx-Power=15 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=58/70 Signal level=-52 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:11 Invalid misc:3627 Missed beacon:0 I've posted a help request before with lots of technical info and outputs.

  • HDMI signal interrputs after 10 minutes plugged in a TV

    - by desert_unbound
    Ubuntu 11.10, Dell Inspiron N4050, VLC, Jupiter I'm trying to watch movies through HDMI output on a TV, with VLC, with the notebook unplugged from AC (but with enough battery for 2-3 hours of use), just with TV display (the notebook display stays off) And from 10 to 10 minutes, the TV turns black, and according to the TV, the HDMI cable is unplugged. But using the touchpad makes the screen appear again. In "screen" options, on system settings, i've set the screen to never turn off, and never reduce brightness using battery. In "power" settings, i've set to not suspend when using battery. In Jupiter, i've set (while trying to watch the movie) to work in maximum performance. I'm pretty sure it's not VLC, because i've set it to override power options and screensaver options (and also im not using xscreensaver). Also the movie continues, when the screen is black Maybe there's something that i'm missing? When i plug the HDMI in the notebook, i use jupiter to change the display (using the option "external display only")... maybe is that ?

  • Examples of Android Joystick Controls? [on hold]

    - by KRB
    I can't seem to find any well executed code examples for Android joystick controls. Whatever it may be, algorithms, pseudo code, actual code examples, strategies, or anything to assist with the design and implementation of Android joystick controls; I can't seem to find anything decent on the net. What are some well executed examples? More specifically, Pseudo Code Current Examples Idea/Design Functionality Description Controller Hints Related Directly to Android Architecture What kind of classes will I have making this? Will there be only one? How would this be implemented to the game architecture? All things I am thinking about. Cheers! UPDATE I've found this on the subject Joystick Example1, though I am still looking for different examples/resources. Answered my own question with a link to the code of the above video. It's a fantastic start to Android Joystick Controls.

  • Notable programs/games made in C/C++/Java/Python? [closed]

    - by ThePlan
    What are some famous programs or video games that were written in the following languages? C C++ Java Python I'm asking this particularly so I know how powerful impact did those languages have on our lives. I believe Windows was also written in C/C++ but I'm not sure if fully. Also if you are kind enough you can mention some other language impacts besides programs/video games. These languages are by far the most common so that's why I've picked them. Besides the impact on our lives I'd also like to see the power these languages have. I'm studying programming and I've learned bits of all those languages and I think if I knew some famous examples of programs written in those languages I could understand the power of them, as well as inspire me further in my career.

  • VHDL gate basics

    - by balina
    Hello. I'm learning VHDL and I've come to a halt. I'd like to create a simple gate out of smaller gates (a NAND gate here). Here's the code: library IEEE; use IEEE.STD_LOGIC_1164.all; entity ANDGATE2 is port( x,y : in STD_LOGIC; z : out STD_LOGIC ); end ANDGATE2; architecture ANDGATE2 of ANDGATE2 is begin z <= x AND y; end ANDGATE2; library IEEE; use IEEE.STD_LOGIC_1164.all; entity NOTGATE1 is port( x : in STD_LOGIC; z : out STD_LOGIC ); end NOTGATE1; architecture NOTGATE1 of NOTGATE1 is begin z <= NOT x; end NOTGATE1; library ieee; use ieee.std_logic_1164.all; entity NANDGATE2 is port( x : in STD_LOGIC; y : in STD_LOGIC; z : out STD_LOGIC ); end NANDGATE2; architecture NANDGATE2 of NANDGATE2 is signal c, d: std_logic; component NOTGATE1 port( n_in : in STD_LOGIC; n_out : out STD_LOGIC ); end component; component ANDGATE2 port( a_in1, a_in2 : in STD_LOGIC; a_out : out STD_LOGIC ); end component; begin N0: ANDGATE2 port map(x, y, c); N1: NOTGATE1 port map(c, d); z <= d; end NANDGATE2; Here's the code from some tutorial I've been using as a template; it compiles with no problems. library ieee; use ieee.std_logic_1164.all; -- definition of a full adder entity FULLADDER is port ( a, b, c: in std_logic; sum, carry: out std_logic ); end FULLADDER; architecture fulladder_behav of FULLADDER is begin sum <= (a xor b) xor c ; carry <= (a and b) or (c and (a xor b)); end fulladder_behav; -- 4-bit adder library ieee; use ieee.std_logic_1164.all; entity FOURBITADD is port ( a, b: in std_logic_vector(3 downto 0); Cin : in std_logic; sum: out std_logic_vector (3 downto 0); Cout, V: out std_logic ); end FOURBITADD; architecture fouradder_structure of FOURBITADD is signal c: std_logic_vector (4 downto 0); component FULLADDER port ( a, b, c: in std_logic; sum, carry: out std_logic ); end component; begin FA0: FULLADDER port map (a(0), b(0), Cin, sum(0), c(1)); FA1: FULLADDER port map (a(1), b(1), C(1), sum(1), c(2)); FA2: FULLADDER port map (a(2), b(2), C(2), sum(2), c(3)); FA3: FULLADDER port map (a(3), b(3), C(3), sum(3), c(4)); V <= c(3) xor c(4); Cout <= c(4); end fouradder_structure; My code compiles with no errors, but with two warnings: # Warning: ELAB1_0026: p2.vhd : (85, 0): There is no default binding for component "andgate2".(Port "a_in1" is not on the entity). # Warning: ELAB1_0026: p2.vhd : (87, 0): There is no default binding for component "notgate1".(Port "n_in" is not on the entity).
