• Which logs will tell me about the Touchpad and Keyboard locking up?

  - by Sepero

  I have an Asus N53SM laptop that I leave running for several weeks at a time. I never put it in hibernate or suspend, I only close the lid when I'm not using it. After a few days or weeks of running, the touchpad and keyboard will Both lock up (at the same time) for no apparent reason. I could be just surfing the internet when it happens. The touchpad and keyboard seem to only lock up when I'm actively using the laptop (not when idle), which may mean it's related to something I press, but I'm not sure? The touchpad never locks or unlocks when Pressing FN and the designated touchpad lock key (it does not seem to work on Linux). While the touchpad and keyboard are locked, I am able to plug in my USB mouse and successfully use it to control the screen cursor. I can also remotely get into the system with vnc and ssh, everything seems to run fine there as well. No processes appear out of control. It's just the laptops physical touchpad and keyboard that are locking up. How might I go about diagnosing this problem? What system logs to look at? (anything specific to look for in them?) Perhaps I should try reloading some modules? Any thing else I should inspect?

• How to re-add a missing font

  - by WEFX

  I recently upgraded from Office 2007 to 2010, and that went fairly smoothly. However, afterwards, my Calibri font was gone, so my Word and Outlook started using the next available font in the list... Comic Sans! I browsed to Control Panel Fonts, and saw that there was no longer a Calibri listing. I know that one way to recover a missing font is to just copy the missing font files from another computer. In my case, the four files I needed were: calibri.ttf, //regular calibrib.ttf, //bold calibrii.ttf, //italics calibriz.ttf, //bold and italics However, once I attempted to copy-and-paste these files to my computer, I realized these files were already on my problem computer; they never really got erased. I don't know why they aren't working in Office, and they aren't listed in Control Panel Fonts.

• Why did Embarcadero make me sign a waiver?

  - by Peter Turner

  Just signed in to the Embarcadero Developer Network and got this: EXPORT CONTROLS ON EMBARCADERO SOFTWARE Your EDN membership and access to Embarcadero Software is subject to your agreement to and compliance with the following terms: -You agree that U.S. export control laws govern your use of the Embarcadero Software. -You are not a citizen, national, or resident of, and are not under control of, the government of Cuba, Iran, Sudan, North Korea, Syria, nor any country to which the United States has embargoed or prohibited export. -You will not provide or export Embarcadero Software, directly or indirectly, to the above mentioned countries nor to citizens, nationals or residents of those countries. -You are not listed on the United States Department of Treasury lists of Specially Designated Nationals, Specially Designated Terrorists, and Specially Designated Narcotic Traffickers, nor are you listed on the United States Department of Commerce Table of Denial Orders. -You will not provide or export the Embarcadero Software, directly or indirectly, to persons on the above mentioned lists. -You will not use the Embarcadero Software for, and will not allow the Embarcadero Software to be used for, any purposes prohibited by United States law, including for the development, design, manufacture or production of nuclear, chemical or biological weapons of mass destruction. I think it's BS, but what craziness is forcing companies like Embarcadero to hold developers to these very high standards? Also, what is "Embarcadero Software"? Does that mean I can't put a benign videogame on a website that may have a runtime that might be downloaded by a Iranian who love scrabble. Or does "Embarcadero Software" refer to anything I develop using Delphi.

• What have you learnt that has a steep learning curve?

  - by Jonathan Khoo

  Recently, I've invested time in learning the intricacies of Git and it has got me thinking about time and learning. (My previous experience with version control systems was only limited use of CVS and SVN.) It took me a whole day's worth of reading to be able to understand the concepts and differences of Git. There are an infinite number of things available for us to learn. Some, more useful than others. I don't know Fortran - I'm relatively young. But looking back at the preceding years of my life, I notice that I'm busier and busier as time goes on. The amount of things I have to get through in a day is increasingly out of my control. It doesn't take a genius to extrapolate that information and realise I'll have even less time in the future - unless I get fired, but I have no strong plans relating to that idea for now. So, given that I have much more time and energy now than I will have in the future: what have you learnt, that has a steep learning curve, that you would possibly recommend to a fellow programmer? Edit: I've stumbled upon the excellent question What programming skills have provided you the best return on investment? and hav realised that my way of approaching how to spend learning time was naive - it doesn't matter if ten useful concepts can be learnt in the time of one if they're worth it.

• Game software design

  - by L. De Leo

  I have been working on a simple implementation of a card game in object oriented Python/HTML/Javascript and building on the top of Django. At this point the game is in its final stage of development but, while spotting a big issue about how I was keeping the application state (basically using a global variable), I reached the point that I'm stuck. The thing is that ignoring the design flaw, in a single-threaded environment such as under the Django development server, the game works perfectly. While I tried to design classes cleanly and keep methods short I now have in front of me an issue that has been keeping me busy for the last 2 days and that countless print statements and visual debugging hasn't helped me spot. The reason I think has to do with some side-effects of functions and to solve it I've been wondering if maybe refactoring the code entirely with static classes that keep no state and just passing the state around might be a good option to keep side-effects under control. Or maybe trying to program it in a functional programming style (although I'm not sure Python allows for a purely functional style). I feel that now there's already too many layers that the software (which I plan to make incredibly more complex by adding non trivial features) has already become unmanageable. How would you suggest I re-take control of my code-base that (despite being still only at < 1000 LOC) seems to have taken a life of its own?

• HTTP Range request rejected

  I am trying to understand why my production environment might be disallowing HTTP RANGE requests. I have a pool of W2K8x64/IIS7 servers behind a pair of Netscaler 9000s. I compose the following request in Fiddler: http://myorigin.example.com/file.flv User-Agent: Fiddler Host: myorigin.example.com Range: bytes=40000-60000 The response looks like: HTTP/1.1 200 OK Cache-Control: public Content-Type: video/x-flv Expires: Thu, 24 Jun 2010 18:23:53 GMT Last-Modified: Sat, 11 Apr 2009 00:16:14 GMT Accept-Ranges: none ETag: f9d5c718-e148-4225-9ca6-d1f91a2a3c08-_633749805744270000 Server: Microsoft-IIS/7.0 Edge-Control: max-age=2592000 X-Powered-By: ASP.NET Date: Tue, 25 May 2010 18:23:53 GMT Content-Length: 443668 "Accept-Ranges: none" tells me that the range request was rejected, but I am not sure where/why as IIS7 accepts Range by default. Could the 'scalers be shooting it down? Thanks, Dan

• New Big Data Appliance Security Features

  - by mgubar

  The Oracle Big Data Appliance (BDA) is an engineered system for big data processing.  It greatly simplifies the deployment of an optimized Hadoop Cluster – whether that cluster is used for batch or real-time processing.  The vast majority of BDA customers are integrating the appliance with their Oracle Databases and they have certain expectations – especially around security.  Oracle Database customers have benefited from a rich set of security features:  encryption, redaction, data masking, database firewall, label based access control – and much, much more.  They want similar capabilities with their Hadoop cluster.    Unfortunately, Hadoop wasn’t developed with security in mind.  By default, a Hadoop cluster is insecure – the antithesis of an Oracle Database.  Some critical security features have been implemented – but even those capabilities are arduous to setup and configure.  Oracle believes that a key element of an optimized appliance is that its data should be secure.  Therefore, by default the BDA delivers the “AAA of security”: authentication, authorization and auditing. Security Starts at Authentication A successful security strategy is predicated on strong authentication – for both users and software services.  Consider the default configuration for a newly installed Oracle Database; it’s been a long time since you had a legitimate chance at accessing the database using the credentials “system/manager” or “scott/tiger”.  The default Oracle Database policy is to lock accounts thereby restricting access; administrators must consciously grant access to users. Default Authentication in Hadoop By default, a Hadoop cluster fails the authentication test. For example, it is easy for a malicious user to masquerade as any other user on the system.  Consider the following scenario that illustrates how a user can access any data on a Hadoop cluster by masquerading as a more privileged user.  In our scenario, the Hadoop cluster contains sensitive salary information in the file /user/hrdata/salaries.txt.  When logged in as the hr user, you can see the following files.  Notice, we’re using the Hadoop command line utilities for accessing the data: $ hadoop fs -ls /user/hrdataFound 1 items-rw-r--r--   1 oracle supergroup         70 2013-10-31 10:38 /user/hrdata/salaries.txt$ hadoop fs -cat /user/hrdata/salaries.txtTom Brady,11000000Tom Hanks,5000000Bob Smith,250000Oprah,300000000 User DrEvil has access to the cluster – and can see that there is an interesting folder called “hrdata”.  $ hadoop fs -ls /user Found 1 items drwx------   - hr supergroup          0 2013-10-31 10:38 /user/hrdata However, DrEvil cannot view the contents of the folder due to lack of access privileges: $ hadoop fs -ls /user/hrdata ls: Permission denied: user=drevil, access=READ_EXECUTE, inode="/user/hrdata":oracle:supergroup:drwx------ Accessing this data will not be a problem for DrEvil. He knows that the hr user owns the data by looking at the folder’s ACLs. To overcome this challenge, he will simply masquerade as the hr user. On his local machine, he adds the hr user, assigns that user a password, and then accesses the data on the Hadoop cluster: $ sudo useradd hr $ sudo passwd $ su hr $ hadoop fs -cat /user/hrdata/salaries.txt Tom Brady,11000000 Tom Hanks,5000000 Bob Smith,250000 Oprah,300000000 Hadoop has not authenticated the user; it trusts that the identity that has been presented is indeed the hr user. Therefore, sensitive data has been easily compromised. Clearly, the default security policy is inappropriate and dangerous to many organizations storing critical data in HDFS. Big Data Appliance Provides Secure Authentication The BDA provides secure authentication to the Hadoop cluster by default – preventing the type of masquerading described above. It accomplishes this thru Kerberos integration. Figure 1: Kerberos Integration The Key Distribution Center (KDC) is a server that has two components: an authentication server and a ticket granting service. The authentication server validates the identity of the user and service. Once authenticated, a client must request a ticket from the ticket granting service – allowing it to access the BDA’s NameNode, JobTracker, etc. At installation, you simply point the BDA to an external KDC or automatically install a highly available KDC on the BDA itself. Kerberos will then provide strong authentication for not just the end user – but also for important Hadoop services running on the appliance. You can now guarantee that users are who they claim to be – and rogue services (like fake data nodes) are not added to the system. It is common for organizations to want to leverage existing LDAP servers for common user and group management. Kerberos integrates with LDAP servers – allowing the principals and encryption keys to be stored in the common repository. This simplifies the deployment and administration of the secure environment. Authorize Access to Sensitive Data Kerberos-based authentication ensures secure access to the system and the establishment of a trusted identity – a prerequisite for any authorization scheme. Once this identity is established, you need to authorize access to the data. HDFS will authorize access to files using ACLs with the authorization specification applied using classic Linux-style commands like chmod and chown (e.g. hadoop fs -chown oracle:oracle /user/hrdata changes the ownership of the /user/hrdata folder to oracle). Authorization is applied at the user or group level – utilizing group membership found in the Linux environment (i.e. /etc/group) or in the LDAP server. For SQL-based data stores – like Hive and Impala – finer grained access control is required. Access to databases, tables, columns, etc. must be controlled. And, you want to leverage roles to facilitate administration. Apache Sentry is a new project that delivers fine grained access control; both Cloudera and Oracle are the project’s founding members. Sentry satisfies the following three authorization requirements: Secure Authorization:  the ability to control access to data and/or privileges on data for authenticated users. Fine-Grained Authorization:  the ability to give users access to a subset of the data (e.g. column) in a database Role-Based Authorization:  the ability to create/apply template-based privileges based on functional roles. With Sentry, “all”, “select” or “insert” privileges are granted to an object. The descendants of that object automatically inherit that privilege. A collection of privileges across many objects may be aggregated into a role – and users/groups are then assigned that role. This leads to simplified administration of security across the system. Figure 2: Object Hierarchy – granting a privilege on the database object will be inherited by its tables and views. Sentry is currently used by both Hive and Impala – but it is a framework that other data sources can leverage when offering fine-grained authorization. For example, one can expect Sentry to deliver authorization capabilities to Cloudera Search in the near future. Audit Hadoop Cluster Activity Auditing is a critical component to a secure system and is oftentimes required for SOX, PCI and other regulations. The BDA integrates with Oracle Audit Vault and Database Firewall – tracking different types of activity taking place on the cluster: Figure 3: Monitored Hadoop services. At the lowest level, every operation that accesses data in HDFS is captured. The HDFS audit log identifies the user who accessed the file, the time that file was accessed, the type of access (read, write, delete, list, etc.) and whether or not that file access was successful. The other auditing features include: MapReduce:  correlate the MapReduce job that accessed the file Oozie:  describes who ran what as part of a workflow Hive:  captures changes were made to the Hive metadata The audit data is captured in the Audit Vault Server – which integrates audit activity from a variety of sources, adding databases (Oracle, DB2, SQL Server) and operating systems to activity from the BDA. Figure 4: Consolidated audit data across the enterprise.  Once the data is in the Audit Vault server, you can leverage a rich set of prebuilt and custom reports to monitor all the activity in the enterprise. In addition, alerts may be defined to trigger violations of audit policies. Conclusion Security cannot be considered an afterthought in big data deployments. Across most organizations, Hadoop is managing sensitive data that must be protected; it is not simply crunching publicly available information used for search applications. The BDA provides a strong security foundation – ensuring users are only allowed to view authorized data and that data access is audited in a consolidated framework.

• Customize the Background in Boxee

  - by DigitalGeekery

  Are you a Boxee user who thinks the default background is little boring? Today we’ll take a look at how to freshen up the look of Boxee by changing the background. Boxee Background When you log into Boxee, select the Settings button at the upper left corner of the Home page.   Select General on the Settings screen. When you select or hover your mouse over the Background Image button, you’ll see options to set a background image or set a background image folder. You’ll have the option of settings a single static image as your background, or choosing an images folder.   If you choose a folder, Boxee will rotate through the images in the folder. To set Background images folder, select that option. Browse for your image folder.. And then select OK.   Boxee will rotate through the images in the folder.   Images will change every ten seconds.   If you prefer a single static image, select Set background image   Choose a image and select OK. Now just enjoy you nice new backgrounds.   If you ever wish to revert back to the default Boxee background, simply select Reset Images on the Settings \ General screen. Adding your own backgrounds is a nice way to customize your Boxee experience. Ideally, you’ll want to choose high resolution images and images oriented as landscape rather than portrait. If you are unfamiliar with Boxee, check out our article on getting started with Boxee.  Looking for a Boxee remote? Read how to use your iPhone or iPod Touch as a Boxee remote.

• deleting old unused images

  - by Ayyash

  As we move on with our content-based websites, lots of images get dumped in our images folder, but we rarely come across self-committed monkyes that delete their files once they do not need it, which means, we end up with a huge list of images in one folder, and it is very tricky to clean it up. My question is (and i dont know if this is the right website to ask it), is there a tool that allows me to find out if an image has been requested by web in the last (n) months? my other general question is, how do you do it? how do you take control of your images folders? what policy do you enforce on developers to clean up? what measures do you take in order to decide what goes and what stays if you end up with an out-of-control situation? my suggestion was to rename the images folder, create a new one, copy the basic ones and wait for someone to complain about a broken image! :) i find this to be the most efficient.

• How to make Xbox joypad work with Bastion?

  - by Alistair Buxton

  I have an XBox joypad: Bus 005 Device 004: ID 045e:0289 Microsoft Corp. Xbox Controller S When I start Bastion from the terminal the following is output: Number of joysticks: 1 Number of buttons for joystick: 0 - 10 Number of axes for joystick: 0 - 6 Number of PovHats for joystick: 0 - 1 When I load up the game it displays a message "press any key" and at this point, if I press a button on the joypad it advances to the main menu. However, the up/down/left/right controls do not work and the button will not operate the menu. When I enter the control configuration, the joypad section is disabled and displays a message "joypad not detected." If I enter the control customization and try to reconfigure one of the controls, noises can be heard when pressing joypad buttons, but the input is otherwise ignored. Further information which may or may not be relevant: My controller is an original Xbox controller, not a 360 controller. XNA games on Windows apparently only work with Xbox360 controllers because they use xinput rather than direct input, see eg here. My controller works (almost) properly with MonoGame trunk samples, but Bastion uses a modified MonoGame and crashes when run against trunk, so I can't add debugging to see where the problem is. Bug can also be reproduced with a Xbox 360 wired controller.

• As a programmer, should I know low and high-level programming languages?

  - by job

  I been contacted to do some work remote controlling LEDs displays over TCP/IP, but my experience and preparation is mostly about high-level programming language. I said that to the person who contact me about the work and he told me that: "if you call yourself a programmer you should know all these things" Should a programmer really know the details of low-level programming? Or can I treat it as a black box concept, as theoretical knowledge but not necessarily doing it or implementing low level language solutions, having in mind that low-level programming is not my expertise?

• Gnome-terminal doesn't close at end of SSH session

  - by Simón

  I have defined in gnome-terminal that it closes at end of shell. When I press Control-D or I execute exit, the terminal closes. But if I open the SSH session with gnome-terminal -x ssh server and I execute reboot in the SSH session (to reboot the remote server), it hangs and it doesn't close. What's happening? This worked to me before but I have to reinstall my Ubuntu (in local) and now gnome-terminal doesn't close itself when SSH session ends.

• Visio 2013 - how to rotate the entire page?

  - by loneboat

  I would like to rotate an entire page, including all of the shapes and text on it. I see here that you can supposedly hold down Control and click-drag the corner of the page to do it: http://office.microsoft.com/en-us/visio-help/rotate-a-page-HP085050946.aspx ... however I can't get this to work. Hovering over the corner does nothing initially, and when I hold Control the cursor becomes a scale/resize icon, rather than a rotate icon (per the MS article I linked to above). I have tried other modifier key combinations while hovering, but nothing seems to produce the rotate icon mentioned.

• New Packt Books: APEX & JRockit

  - by [email protected]

    I have received these 2 ebooks from Packt Publkishing and I am currently reviewing them. Both of them look great so far.   Oracle Application Express 3.2 - The Essentials and More First of all, I have to mention that I am new to APEX. I was interested on this product which is a development tool for Web applications on the Oracle Database. As I support JDeveloper and ADF, which are products that work very closely with the Oracle Database and are a rapid development tool as well, it is always interesting and useful to know complementary tools. APEX looks very useful and the book includes many working examples. A more complete review of this book is coming soon. Further information about this book can be seen at Packt.   Oracle JRockit: The Definitive Guide Many of our Oracle Coherence customers run their caches and clusters using JRockit. This JVM has helped us to solve lots of Service Requests. It is a really reliable, fast and stable JVM. It works great on both development and production environments with big amounts of data, concurrency, multi-threading and many other factors that can make a JVM crash. I must also mention JRockit Mission Control (JRMC), which is a great tool for management and monitoring. I really recommend it. As a matter of fact, some months ago, I created a document entitled "How to Monitor Coherence-Based Applications using JRockit Mission Control" (Doc Id 961617.1) on My Oracle Support. Also, the JRockit Runtime Analyzer (JRA) and it successor of newer versions, the JRockit Flight Recorder (JFR) are deeply reviewed. This book contains very clear and complete information about all this and more. I will post an entry with a more complete review soon (and will probably post an entry about Coherence monitoring with JRMC soon too). Further information about this book can be seen at Packt.

• JRockit R28 "Ropsten" released

  - by tomas.nilsson

  R28 is a major release (as indicated by the careless omissions of "minor" and "revision" numbers. The formal name would be R28.0.0). Our customers expect grand new features and innovation from major releases, and "Ropsten" will not disappoint. One of the biggest challenges for IT systems is after the fact diagnostics. That is - Once something has gone wrong, the act of trying to figure out why it went wrong. Monitoring a system and keeping track of system health once it is running is considered a hard problem (one that we to some extent help our customers solve already with JRockit Mission Control), but doing it after something occurred is close to impossible. The most common solution is to set up heavy logging (and sacrificing system performance to do the logging) and hope that the problem occurs again. No one really thinks that this is a good solution, but it's the best there is. Until now. Inspired by the "Black box" in airplanes, JRockit R28 introduces the Flight Recorder. Flight Recorder can be seen as an extremely detailed log, but one that is always on and that comes without a cost to system performance. With JRockit Flight Recorder the customer will be able to get diagnostics information about what happened _before_ a problem occurred, instead of trying to guess by looking at the fallout. Keywords that are important to the customer are: • Extremely detailed, always on, diagnostics information • No performance overhead • Powerful tooling to visualize the data recorded. • Enables diagnostics of bugs and SLA breaches after the fact. For followers of JRockit, other additions are: • New JMX agent that allows JRMC to be used through firewalls more easily • Option to generate HPROF dumps, compatible with tools like Eclipse MAT • Up to 64 BG compressed references (previously 4) • View memory allocation on a thread level (as an Mbean and in Mission Control) • Native memory tracking (Command line and Mbean) • More robust optimizer. • Dropping support for Java 1.4.2 and Itanium If you have any further questions, please email [email protected]. The release can be downloaded from http://www.oracle.com/technology/software/products/jrockit/index.html

• Character progression through leveling, skills or items?

  - by Anton

  I'm working on a design for an RPG game, and I'm having some doubts about the skill and level system. I'm going for a more casual, explorative gaming experience and so thought about lowering the game complexity by simplifying character progression. But I'm having trouble deciding between the following: Progression through leveling, no complex skill progression, leveling increases base stats. Progression through skills, no leveling or base stat changes, skills progress through usage. Progression through items, more focus on stat-changing items, items confer skills, no leveling. However, I'm uncertain what the effects on gameplay might be in the end. So, my question is this: What would be the effects of choosing one of the above alternatives over the others? (Particularly with regards to the style and feel of the gameplay) My take on it is that the first sacrifices more frequent rewards and customization in favor of a simpler gameplay; the second sacrifices explicit customization and player control in favor of more frequent rewards and a somewhat simpler gameplay; while the third sacrifices inventory simplicity and a player metric in favor of player control, customization and progression simplicity. Addendum: I'm not really limiting myself to the above three, they are just the ones I liked most and am primarily interested in.

• Compiz not drawing window controls in ubuntu 11.10

  - by Siva Prasad Varma

  I have recently installed driver for my ATI graphic card in my Dell Studio laptop. I have also read this somewhere on the web that Ubuntu enables compiz window manager by default if your hardware can run it. Is it true ? In my case before Installing graphic card driver the window manager was Metacity, but now I have compiz as my Window manager. I found this out uisng Displex Indicator applet also confirmed by wmctrl -m. From the time I have installed graphic card drivers, the window manager(Compiz) is not drawing window control buttons for some of the windows. For example if I open a terminal I have to close it using key board shortcuts or use the File - Quit option in app-menu. Also I am not able to move the window because of this. From then when-ever I find a window without window control buttons I am restarting the window manager using Displex Indicator applet. But this is very annoying and also consumes a lot of time(when I am doing my work). Can any one suggest any solution for this. What are up's and down's of using Compiz Vs Metacity.

• Oracle releases new Java Embedded products

  - by Henrik Stahl

  With less than one week to go to JavaOne 2012, we've spiced things up a little by releasing not one but two net new embedded Java products. This is an important step towards realizing the vision of Java as the standard platform for the Internet of Things that I outlined in a recent blog post. The two new products are: Java ME Embedded 3.2. Based on same code as the widely deployed Oracle Java Wireless Client for feature phones, this new product provides a Java ME implementation optimized for very small microcontroller-based devices and adds - among other things - a new Device Access API that enables interaction with peripherals common in edge devices such as various types of sensors. In addition to the new Java ME Embedded platform, we have also released an update of the Java ME SDK which adds support for the development of small embedded devices. Java Embedded Suite 7.0. This is an integrated middleware stack for embedded devices, incorporating Java SE Embedded and versions of JavaDB, GlassFish and a Web Services stack optimized for remote operation and small footprint. A typical Internet of Things (or M2M) infrastructure contains three types of compute nodes: The edge device which is typically a sensor or control point of some kind. These devices can be connected directly to a backend through a mobile network if they are installed in - for example - a remote vending machine; or, they can be part of a local short-range network and be connected to the backend through a more powerful gateway device. A gateway is the second type of compute node and acts as an aggregator and control point for a local network. A good example of this could be a generalized home Internet access point, or home gateway. Gateways are mostly using normal wall power and are used for multiple applications, deployed by multiple service providers. Finally, the last type of compute node is the normal enterprise or cloud backend. Java ME Embedded and Java Embedded Suite are perfect base software stacks for the edge devices and the gateway respectively, providing the Java promise of a platform independent runtime and a complete set of libraries as well as allowing a programmer to focus on the business logic rather than plumbing. We are very thrilled with these new releases that open up exciting opportunities for Java developers to extend services and enterprise applications in ways that will make organizations more efficient and touch our daily lives. To find out more, come to the JavaOne conference (for technical content) and to the Java Embedded @ JavaOne subconference (for business content). There will be plenty of cool demos showing complete end-to-end applications, provided by Oracle and our partners, as well as keynotes and numerous sessions where you can learn more about the technology and business opportunities.
