• Oracle GoldenGate 12c - Leading Enterprise Replication

  - by Doug Reid

  Oracle GoldenGate 12c released  on October 17th and includes several new cutting edge features that firmly establishes GoldenGate's leader position in the data replication space.   In fact, this release more than doubles the performance of data delivery, supports Oracle's new multitenant database feature,  it's more secure, has more options for high availability, and has made great strides to simplify the configuration and deployment of the product.     Read through the press release if you haven't already and do not miss the quote from Cern's Eva Dafonte Perez, regarding Oracle GoldenGate 12c "….performs five times faster compared to previous GoldenGate versions and simplifies the management of a multi-tier environment" There are a variety of new and improved features in the Oracle GoldenGate 12c.  Here are the highlights: Optimized for Oracle Database 12c -  GoldenGate 12c is custom tailored to the unique capabilities of Oracle database 12c and out of the box GoldenGate 12c supports multitenant (pluggable database (PDB)) and non-consolidated deployments of Oracle Database 12c.   The naming convention used by database 12c is now in three parts (PDB-name, schema-name, and object name).  We have made changes to the GoldenGate capture process to support the new naming convention and streamlined the whole process so a single GoldenGate capture process is being used at the container level rather than at each individual PDB.  By having the capture process at the container level resource usage and the number of processes are reduced. To view a conceptual architecture diagram click here. Integrated Delivery for the Oracle Database - Leveraging a lightweight streaming API built exclusively for Oracle GoldenGate 12c, this process distributes load, auto tunes the degree of parallelism, scales better, and delivers blinding rates of changed data delivery to the Oracle database.  One of the goals for Oracle GoldenGate 12c was to reduce IT costs by simplifying the configuration and reduce the time to manage complex infrastructures.  In previous versions of Oracle GoldenGate, customers would split transaction loads by grouping tables into multiple different delivery processes (click here to view the previous method). Each delivery process executed independently and without any interaction or knowledge of other delivery processes.  This setup was complicated to configure and time consuming as the developer needed in-depth knowledge of the source and target schemas and the transaction profile. With GoldenGate 12c and Integrated Delivery we have made it easier to configure and faster to deploy.  To view a conceptual architecture diagram of integrated delivery click here Coordinated Delivery for Non-Oracle Databases - Coordinated Delivery orchestrates high-speed apply processes and simplifies the configuration of GoldenGate for non-Oracle targets. In Oracle GoldenGate 12c a single delivery process is used with multiple threads (click here) and key events, such as primary key updates, event markers, DDL, etc, are coordinated between the various threads to insure that the transactions are applied in the same sequence as they were captured, all while delivery improved performance.  Replication Between On-Premises and Cloud-Based systems. - The trend for business to utilize both on-premises and cloud-based systems is rising and businesses need to replicate data back and forth.   GoldenGate 12c can be configured in a variety of ways to provide real-time replication when unrestricted or restricted (limited ports or HTTP tunneling) networks are between on-premises and cloud-based systems.    Expanded Heterogeneity - It wouldn't be a GoldenGate release without new and improved platform support.   Release 1 includes support for MySQL 5.6 and Sybase 15.7.   Upcoming in the next release GoldenGate, support will be expanded for MS SQL Server, DB2, and Teradata. Tighter Security - Oracle GoldenGate 12c is integrated with the Oracle wallet to shield usernames and passwords using strong encryption and aliases.   Customers accustomed to using the Oracle Wallet with other Oracle products will instantly be familiar with how to use this great new feature Expanded Oracle Application and Technology Support -   GoldenGate can be used along with Oracle Coherence to enable real-time changed data feeds to the Coherence cache using Toplink and the Oracle GoldenGate JMS adapter.     Plus,  Oracle Advanced Customer Services (ACS) now offers a low downtime E-Business Suite platform and database migrations using GoldenGate as the enabling technology.  Keep tuned for more blogs on the new features and the upcoming launch webcast where we will go into these new features in more detail.   In the mean time make sure to read through our white paper "Oracle GoldenGate 12c Release 1 New Features Overview"

• Process Centric Banking: Loan Origination Solution

  - by Manish Palaparthy

  There is an old proverb that goes, "The difference between theory and practice is greater in practice than in theory". So, we keep doing numerous "Proof of Concepts" with our own products on various business cases to analyze them deeply, understand and explain to our customers. We then present our learnings as they happened. The awareness of each PoC should help readers increase the trustworthiness of the results coming out of these PoCs. I present one such PoC where we invested a lot of time&effort.  Process Centric Banking : Loan Origination Solution Loan Origination is a process by which a borrower applies for a new loan and the lender processes that application. Loan origination includes the series of steps taken by the bank from the point the customer shows interest in a loan product all the way to disbursal of funds. The Loan Origination process is relevant for many kind of lenders in Financial services: Banks, Credit Unions, NBFCs(Non Banking Financial Companies) and so on. For simplicity sake, I will use "Bank" as the lending institution in the rest of my article.  Loan Origination is one of the core processes for Banks as it is the process by which the it creates assets against which the Institution earns most of its profits from. A well tuned loan origination process can affect the Bank in many positive ways. Banks have always shown great interest in automating the loan origination process for the above reason. However, due the constant changes in customer environment, market dynamics, prevailing economic conditions, cost pressures & regulatory environment they run into lot of challenges. Let me categorize some of these challenges for you Customer Environment Multiple Channels: Customer can use any of the available channels (Internet Banking, Email, Fax, Branch, Phone Banking, ATM, Broker, Mobile, Snail Mail) to perform all or some of the activities related to her Visibility into the origination process: Expect immediate update on the status of loan processing & alert messages Reduced Turn Around Time: Expect loans to be processed with least turn around time Reduced loan processing fees: Partly due to market dynamics the customer expects the loan processing fee to be negligible Market Dynamics Competitive environment:  The competition keeps creating many variants of loan products to attract customers, the bank needs to create similar product variants with better offers to attract customers or keep existing ones Ability to migrate loans from one vendor to another: It has become really easy for retail customers to move from one bank to the other given the low fee of loan processing and highly attractive offers. How does the bank protect it's customer base while actively engaging with potential customers banking with competitor banks Flexibility to react to market developments: Market development greatly influence loan processing, underwriting, asset valuation, risk mitigation rules. Can the bank modify rules and policies, the idea is not just to react to market developments but to pro-actively manage new developments Economic conditions Constant change in various rates and their implications on the rates and rules applied when on-boarding a loan: How quickly can the bank apply changes to rates offered to customers when the central bank changes various rates Requirements of Audit by the central banker: Tough economic conditions have demanded much more stringent audit rules and tests. The banks needs to produce ready reports(historic & operational) for audit compliance Risk Mitigation: While risk mitigation has always been a key concern for the bank, this is the area where the bank's underwriters & risk analysts spend the maximum time when processing a loan application. In order to reduce TAT the bank cannot compromise on its risk mitigation strategies Cost pressures Reduce Cost of processing per application: To deliver a reduced loan processing fee to the customer, the bank needs to keep its cost per processing loan application low. Meet customer TAT expectations while reducing the queues and the systems being used to process the loan application: The loan application could potentially be spending a lot of time waiting in the queue for further processing. Different volumes & patterns of applications demand different queuing algorithms. The bank needs to have real-time visibility into these queues and have the flexibility to change queuing algorithms at runtime  Increase the use of electronic communication and reduce the branch channel usage: Lesser automation leads not only leads to Increased turn around time, it also impacts more costs to reach out to customers The objective of our PoC was to implement a Loan Origination Solution whose ownership lies with the bank and effectively meet the challenges listed above. We built a simple story board for the solution We then went about implementing our storyboard using Oracle BPM Suite, Webcenter Content : Imaging. The web UI has been built on ADF technolgies, while the integration with core-services has been implemented using the underlying SOA infrastructure. The BPM process model is quite exhaustive can meet all the challenges listed above to reasonable degree. A bank intending to implement an end-to-end Loan Origination Solution has multiple options at it's disposal. It can Develop a customer Loan Origination Application from scratch: Gives maximum opportunity to build what you want but inflexible to upgrade and maintain. Higher TCO in long term Buy a Packaged application & customize it: Customizing a generic loan application can be tedious and prove as difficult as above. Build it using many disparate & un-integrated tools: Initially seems easier than developing from scratch. But, without integrated tool sets this is not a viable approach either or A solution based on a Framework: Independent Services and Business Process Modeling provide decoupled architecture that is flexible. We built this framework end-to-end with processes the core process of loan origination & several sub-processes such as Analyse and define customer needs, customer credit verification, identity check processes, legal review process, New customer registration & risk assessment.

• How can we stop GitHub from emailing too many people too much? [migrated]

  - by Michael Bishop

  I recently joined a research team that uses R and Git/GitHub. The team includes 4 full-time R programmers and 10 social scientists who only run simple analyses. I was told by one of the more experienced programmers on the project that they haven't found a way to use many of GitHub's tools for collaboration (bug reports, to-do lists, code comments, etc.) because they generate emails to everyone who is a contributor to the repo every time. This is incredibly puzzling to me, so I'd love to hear from someone that there are ways to adjust the email settings. I'd expect there would be multiple ways, so that individuals could opt-in or opt-out of certain emails, and also so contributors could explicitly choose whether certain people get certain emails or not. Is it possible to adjust these settings?

• Firefox profile issue

  - by vooda gopal

  Is there any limit in the number of firefox profiles that can be created? My issue is I am currently doing selenium webdriver automation in linux for a device. There are 50 devices of same kind and framework will pickup a device depending on availability. I need to by pass unsigned ssl pages. I am using firefox 14. I have implemented following but it is not consistent. everytime a device is chosen adds cer of device to the cert file in firefox profile but I am getting sec_error_bad_signature very frequently. So I started recreating cert [delete and create if by opening firefox] file for every run. Now this is posing a problem if multiple devices are run at the same time. Hence I want to create separate firefox profile

• My events don't show up in the goal funnels or conversion funnels

  - by Amit Bens

  I have an event set up on a website and I'd like to track the effect this event has on conversion rate. The event seems to be working fine - I can see it on Top Events with all the labels, etc. But when going into Goal Flow and selecting 'Event Category' these events don't show up. I have this running for about a week. And I have made multiple checks to verify that I have events that triggered the conversion goal. Any clue about what I'm doing wrong?

• How do multi-platform games usually store save data?

  - by PixelPerfect3

  I realize this is a bit of a broad question, but I was wondering if there is a "standard" in the industry when it comes to storing save data for games (and is it different across platforms - Xbox/PS/PC/Mac/Android/iOS?) For example for a game like Assassin's Creed or The Walking Dead: They are on multiple platforms and they usually have to save enough information about the player and their actions. Do they use something like XML files, databases, or just straight binary dumps? How much does it differ from platform to platform? I would appreciate it if someone with experience in the game industry would answer this.

• How do I inject test objects when the real objects are created dynamically?

  - by JW01

  I want to make a class testable using dependency injection. But the class creates multiple objects at runtime, and passes different values to their constructor. Here's a simplified example: public abstract class Validator { private ErrorList errors; public abstract void validate(); public void addError(String text) { errors.add( new ValidationError(text)); } public int getNumErrors() { return errors.count() } } public class AgeValidator extends Validator { public void validate() { addError("first name invalid"); addError("last name invalid"); } } (There are many other subclasses of Validator.) What's the best way to change this, so I can inject a fake object instead of ValidationError? I can create an AbstractValidationErrorFactory, and inject the factory instead. This would work, but it seems like I'll end up creating tons of little factories and factory interfaces, for every dependency of this sort. Is there a better way?

• How can I get six Xbox controllers to provide input to an HTML5 game?

  - by Daniel X Moore

  I'm creating a six player HTML 5 game designed to be played locally (Red Ice). I've previous set up handling 7 Wiimotes using something along the lines of Joy2Key to map each input for each player to a separate keyboard key, but Wiimotes are pretty hard on the hands for these types of games and not very ergonomic so I thought I'd try and get Xbox controller support. I don't believe that any simple key mapping solution will work due to the nature of the directional stick. My inclination is that this will require a browser plugin and if so I'd prefer to write the plugin for Google Chrome. How do I create a Chrome browser plugin to handle multiple Xbox controllers or is there some other way? Please do not answer this question saying it can't be done, because it absolutely can. EDIT: I don't believe any keymapping/mouse simulating solution will work unless it can reliably distinguish six axis of inputs, one per player.

• GameState management hierarchical FSM vs stack based FSM

  - by user8363

  I'm reading a bit on Finite State Machines to handle game states (or screens). I would like to build a rather decent FSM that can handle multiple screens. e.g. while the game is running I want to be able to pop-up an ingame menu and when that happens the main screen must stop updating (the game is paused) but must still be visible in the background. However when I open an inventory pop-up the main screen must be visible and continue updating etc. I'm a bit confused about the difference in implementation and functionality between hierarchical FSM's and FSM's that handle a stack of states instead. Are they basically the same? Or are there important differences?

• How to import in BIDS more than one SSIS package in one shot!

  - by Luca Zavarella

  Have you ever wanted to add more than one Integration Services existing package (e.g. 20 packages) in a SSIS project? Well, you may suppose that an Open Dialog supports multiple files selection to import more than one file at a time ... BIDS Open Dialog doesn’t allow this, you can just select a single file! Hence the loss of valuable time spent to import the packages one at a time. Few days ago I learned a trick that solves the problem, thanks to this post by Matt Masson. Just copy all the packages to import from Windows Explorer (Ctrl + C): Then just right click on the SSIS Packages folder of the Integration Services project and make a simple Past (CTRL + V): So “auto-magically” you’ll have all those packages imported in your Integration Services project!! What can I say... this feature was well hidden!

• Understanding the problem when things break in production

  - by bitcycle

  Scenario: You push to production The push broke multiple things That same build did not break qa or dev As a developer, you don't have prod access. There is lots of pressure from above to get things working agian. Specifics: PHP/MVC application that is API-driven in Zend. Deployed to a few servers. My question: While investigating, lets say I have a hunch that something is wrong. But, I don't know for sure. And, of course, I can't test things in production. If I have a suggested fix based on that hunch, would it be wise to try and apply it and see if it works, before understanding what the problem is?

• How can I fix TTF fonts' ligatures (tt, ti, fi, ff, etc) in Firefox?

  - by Oli

  With certain Windows fonts there is a display issue where ligature-kerning seems to flip out and make the two letters bold. Here's a screenshot of an email using Helvetica in Firefox: As you can see, it seems to be something about the way crossed characters (t and f) connect to each other and letters like i. I've had this problem for a very long time (over multiple systems) and wondered if anybody has ever seen similar issues popping up and found a way to fix them. Note: I think this does just affect Firefox. Chrome and LibreOffice are both fine.

• Transparency in XNA-4 primitives

  - by Shashwat

  I'm using XNA 4 with Visual Studio 2010. I'm trying to create a simple 3D world with walls and doors in which the user to free to roam around. A wall is just a rectangle which is currently being rendered with four vertices using triangle strips. But to create a door, I'd have to split it into three rectangles as shown in the figure. Four quadrilaterals if I want to have the following door-style It will become more complex to have multiple doors on the same wall or if I have windows. Is there any shorter way to handle this? I am looking for something that will just make the wall transparent wherever I want. I found a solution but facing a problem here

• Java Plugin - Firefox

  - by Tomassino

  Having trouble getting Java to work with Firefox (22), I have followed the advice in this question and on the official Java site, but nothing seems to work. I have the latest Java (1.7.0_25) in /opt/java and have set a symlink in /usr/libs/mozilla/plugins for the libnpjp2.so file. I can see the file in the terminal and Java runs fine. However Firefox shows nothing in about:plugins. I have also run export JAVA_HOME="/opt/java/jre1.7.0_05/bin/java" to be on the safe side. I know there are multiple plugin directories such as /usr/lib/firefox/plugins and /usr/lib/firefox-addons/plugins, but all my current plugins show they are located in /usr/lib/mozilla/plugins when viewing the about:plugins page. A bit stuck on where to go next?

• The Information Driven Value Chain - Part 1

  - by Paul Homchick

  One hundred years ago, there were places on Earth that no man had ever seen.  Today, a man standing in one of those places can instantaneously communicate with someone who may be strolling down the street on his way to lunch half way around the globe.  Our world is shrinking and becoming virtual. It is a world of incredible bounty and speed where we can get a product delivered to us anywhere on earth within a day or two. However, this world is also one of challenge where volatility, uncertainty, risk and chaos are our daily companions. To prosper amid the realities of this new world, the enterprise needs a business model. Globalization and instant communications demand greater operational flexibility than ever before. Extended supply chains have elevated the management of risk to a central concern, and regulatory demands from multiple governments place an increasing burden of compliance on companies. Finally, the speed of today's business requires continuous innovation to keep from falling behind the global competition.

• How to Save Filters with PNG in Inkscape

  - by Uri Herrera

  I have created a graphic with multiple layers in Inkscape. One of the layers is some text. I have applied a drop shadow filter to the text. When I save the file as PNG, the drop shadow is not saved. I have also tried applying a gaussian blur to the text layer and to the text layer after converting it to an object. The blur is not applied. How can I save the file as PNG with the drop shadow intact?

• Keystore and Credential Store interplay in OWSM - 11g

  - by Prakash Yamuna

  One of the most common problems faced by customer's is the use of the keystore and it's interplay with the credential store.Here is a picture that describes these relationships.(Click on the picture for a larger image). The picture makes some assumptions in describing the relationship. Some of assumptions are: a) the key used for signing and encryption are the same. b) A keystore can have multiple keys and each key can have it's own alias. In the picture I show only a single key with alias "orakey". c) The keystore being described here is a JKS keystore. Things can vary slightly for other type of keystores. I hope to have a detailed How To that provides the larger picture and then shows these relationships in that context and this picture was created in the context of that How-To. However I think people will find this picture useful on a standalone basis as well. The <serviceInstance> is the entry you will find in jps-config.xml

• Does a programmer really need college?

  - by Dfranc3373

  I am currently a junior in college, however I have had multiple jobs programming since high school. Currently I work programming at a company part time using many different languages that I have learned the past few years. I recently sat down with a advisor and discovered with the classes I have left to take, I will learn next to nothing in them, as I already know the concepts and how to apply them for all the classes. My current job has offered me a full time position and I have had other companies email me as well. My question is if I know for a fact that I cannot learn more at college, is there even a point in staying? I know for a fact I could spend my time in more productive ways programming and working then what I am doing in school. Do you think to be looked at seriously as a programmer you need a degree?

• Log oddities: 404s for client-garbled image URLs

  - by Chris Adams

  I've noticed some odd 404s which appear to be broken URL rewriting code: Our deep zoom view generates images URLs like this: /media/204/service/dzi/1/1_files/7/0_0.jpg I see some - well under <1% - requests for slightly altered URLs: /media/204/s/rvice/d/i/1/1_files/7/0_0.jpg These requests come from IP addresses all over the world (US, Canada, China, Russia, India, Israel, etc.), desktop and mobile users with multiple user-agents (Chrome, IE, Firefox, Mobile Safari, etc.), and there is plenty of normal activity in the same session so I'm assuming this is either widespread malware or some broken proxy service. I have not seen them from anything other than images, which suggests that this may be some sort of content filter. Has anyone else seen this? My CDN logs show the first request on June 8th ramping up from several dozen to several hundred per day.

• cross resolution level design advice [on hold]

  - by Mike

  I was looking for some beginner advice regarding level design across multiple resolutions. I believe the answer is likely "it depends", but any input from anyone with real experience is very appreciated. Basically, I am building a 2D Super Metroid type game. If rooms/levels are to be a tiled grid, what are some general best practices for designing rooms when taking into account different resolutions? Since more or less tiles could fit vertically on a single screen depending on the resolution, is it better to design towards possibly having more of the room visible depending on the screen (with a bare minimum needed for gameplay), or should I fix the design at a certain tile height and scale the graphics?

• Magento Checkout options

  - by graham barnes

  Hi I want to add some options to my magento, lets say i print on clothing, a customer buys some t-shirts, shirts and jackets from me, it totals to £60+ VAT on the checkout area where i signup and not before I need to add an option where I can add a text box and upload option, can i do this? I ideally then want to add some pricing options if the user has chosen to add some branding to a product or multiple products e.g. if the branding was on the top right of the shirt it will cost £5.00, if on the back it costs £7.00 etc all if possible to be done via the admincp. I also want an option so when they upload their logo for the first time they are charged a one off charge, like a setup fee but If the customer has allready sent in there logo then no charge applies. thanks Graham

• How do I Fallback to Older DirectX Versions?

  - by smoth190

  I had a feeling that it would be easier to tackle this problem before I got too deep into development (unless, of course if that's a bad idea/the hard way, please inform me...). I'm creating my game to be run ideally on DirectX 11, however, I want to offer it on DirectX 10, and I'm unsure if it is worth offering it for DirectX 9 for XP users. I'm not too sure how this fallback even works, as I can't find many articles on the internet. If someone could give me an in-depth article, that would be great. I've read a little about how since DirectX11 is completely absent on XP, it is hard to even check for support. Someone mentioned having multiple applications for each version, is this a good idea? Thanks to anyone who can point me in the right direction here.

• Batch file to Delete Old Virtual Directories.

  - by Michael Freidgeim

  On some servers we have many old Virtual Directories created for previous versions of our application. IIS user interface allows to delete only one in a time. Fortunately we can use IIS scripts as described in How to manage Web sites and Web virtual directories by using command-line scripts in IIS 6.0 I've created batch file DeleteOldVDirs.cmd rem http://support.microsoft.com/kb/816568 rem syntax: iisvdir /delete WebSite [/Virtual Path]Name [/s Computer [/u [Domain\]User /p Password]] REM list all directories and create batch of deletes iisvdir /query "Default Web Site" echo "Enter Ctrl-C  if you want to stop deleting" Pause iisvdir /delete "Default Web Site/VDirName1" iisvdir /delete "Default Web Site/VDirName2" ...   If the name of WebSite or Virtual directory contain spaces(e.g  "Default Web Site"), don't forget to use double quotes. Note that the batch doesn't delete physical directories from flie system.You need to delete them using Windows Explorer, but it does support multiple selection!

• Using C++11 for cross-platform Game Engine Development

  - by Samaursa

  Note: This is not a 'give your opinion' question about C++03 and C++11. Our game engine, written in C++03, is designed to be compiled on Windows, OSX and iOS. Linux support is planned for the (very) near future. Our experience is limited when it comes to consoles, which is why I am asking this question. Currently, we are debating whether switching to C++11 and using non-compatible features of the C++11 standard could pose a problem in the near future when we need to port our engine to any of the current gen consoles (perhaps the compilers supported by some console(s) do not support C++11 yet? We don't know...). So, game developers who have experience across multiple platforms and consoles, do you think we should stick to C++03 until the new generation of consoles arrive and most everybody has switched to C++11 standard (have they already?). Or are most consoles using/support compilers (VC++, GCC or variants?) that are already supporting C++11 features?
