  • Serverside memory efficiency and threading for a turn based game

    - by SkeletorFromEterenia
    Im programming on a turn based war-game for some years now (along with the engine) and Im having quite a hard time at figuring out what the games server architecture should look like, since most game server architecture articles I found focus either on FPS oder MMOGs, which doesn't really fit since I want many matches with 1- 16 players on my server, with each match being played in turn based mode. My chief concern is memory usage, since the most basic approach of loading every game that is being played completely into RAM should be quite inefficient, so is there a suitable strategy for selecting only the needed bits and loading them? Another question I got is how to design the threading on the server, since I think using only a single thread could be a problem due to the fact that the game or part of it might have to be loaded from the database. I would be very happy if you could share your knowledge or point me to material on this topic.

  • Cannot Create a connection to Data Source VB 2010 [closed]

    - by CLO_471
    I seem to be having some issues with my Visual Basic 2010. I am trying to create a connection to a data source and it is just not working. Even my old connections in my other projects are not working. When I get into VB I try and create a connection by clicking Add New Data Source Database DataSet New Connection and when I click on New Connection the screen disappears and I am not able to select anything. Does anyone know of a glitch or something? I have checked my ODBC connections and all is good and I have been able to play around with my Access connections (which I am trying to connect) and Queries and everything seems to be working fine. I have rebooted several times, uninstalled and resinstalled VB and have also repaired the entire application. I am not sure what else to try or what else to do. Any help would be much appreciated. My computer specs are XP SP3, Core2 Duo at 2.80 and 3GB RAM

  • How to explain to non-technical person why the task will take much longer then they think?

    - by Mag20
    Almost every developer has to answer questions from business side like: Why is going to take 2 days to add this simple contact form? When developer estimates this task, they may divide it into steps: make some changes to Database optimize DB changes for speed add front end HTML write server side code add validation add client side javascript use unit tests make sure SEO is setup is working implement email confirmation refactor and optimize the code for speed ... These maybe hard to explain to non-technical person, who basically sees the whole task as just putting together some HTML and creating a table to store the data. To them it could be 2 hours MAX. So is there a better way to explain why the estimate is high to non-developer?

  • La ville de Paris rejoint le mouvement OpenData, et publie sous licence libre les données de ses services municipaux

    La ville de Paris rejoint le mouvement OpenData, et publie sous licence libre les données de ses services municipaux Le mouvement OpenData vient de faire une nouvelle adepte : la ville de Paris. La démarche de ce groupe est de pousser le plus de gouvernements et d'organisations possibles à publier en ligne leurs données brutes (bases de données, systèmes d'information cartographiques, registres électroniques, etc.), afin que les scientifiques, analystes, développeurs et entrepreneurs puissent les utiliser pour les étudier, ou pour créer des services innovants. La France ouvre donc le site ParisData, qui, sous licence Open Database, diffuse des informations relatives aux citoyens de la ville, mais aussi à ses transports, sa politiqu...

  • Why is prefixing column names considered bad practice?

    - by P.Brian.Mackey
    According to a popular SO post is it considered a bad practice to prefix table names. At my company every column is prefixed by a table name. This is difficult for me to read. I'm not sure the reason, but this naming is actually the company standard. I can't stand the naming convention, but I have no documentation to back up my reasoning. All I know is that reading AdventureWorks is much simpler. In this our company DB you will see a table, Person and it might have column name: Person_First_Name or maybe even Person_Person_First_Name (don't ask me why you see person 2x) Why is it considered a bad practice to pre-fix column names? Are underscores considered evil in SQL as well? Note: I own Pro SQL Server 2008 - Relation Database design and implementation. References to that book are welcome.

  • Functional or non-functional requirement?

    - by killer_PL
    I'm wondering about functional or non-functional requirements. I have found lot of different definitions for those terms and I can't assign some of my requirement to proper category. I'm wondering about requirements that aren't connected with some action or have some additional conditions, for example: On the list of selected devices, device can be repeated. Database must contain at least 100 items Currency of some value must be in USD dollar. Device must have a name and power consumption value in Watts. are those requirements functional or non-functional ?

  • Oracle Technology Network Newsletters Revisited

    - by Justin Kestelyn
    You may find this hard to believe, some analysts content that email newsletters are still among the most preferred methods of "information awareness" by developers today. And in our experience, the numbers back it up: subscriptions to Oracle Technology Network newsletters grow organically by 15% every year, even after you take continual list cleanup into account. At this point, we have honed our newsletter strategy to a fine edge; the choices are now: Oracle's Java Developer Newsletter Oracle's Database Application Developer Newsletter (also suitable for DBAs) Oracle's Architect Community Newsletter Oracle's Solaris Community Newsletter (new!) Oracle's .NET Developer Newsletter All of which you can subscribe to here; sample issues also available. Have a taste, you'll like them!

  • All day optimizer event....

    - by noreply(at)blogger.com (Thomas Kyte)
    I've recently taken over some of the responsibilities of Maria Colgan (also known as the "optimizer lady") so she can move onto supporting our new In Memory Database features (note her new twitter handle for that: https://twitter.com/db_inmemory ).To that end, I have two one day Optimizer classes scheduled this year (and more to follow next year!).  The first one will be Wednesday November 20th in Northern California.  You can find details for that here: http://www.nocoug.org/ .The next one will be 5,500 miles (about 8,800 km) away in the UK - in Manchester.  That'll take place immediately following the UKOUG technical conference taking place the first week of December on December 5th.  You can see all of the details for that here: http://www.ukoug.org/events/tom-kyte-seminar-2013/I know I'll be doing one in Belgrade early next year, probably the first week in April. Stay tuned for details on that and for more to come.

  • Is the Mailchimp API available in other languages?

    - by boundaryfunctions
    I'm using the Mailchimp API in combination with PHP and jQuery to provide the subscribing/unsubscribing-actions on a website via Ajax. On errors with user data you get useful messages like "Invalid Email Address", "[email protected] is already subscribed to list x. Click here to update your profile." or "There is no record of "[email protected]" in the database". For sure I want to keep theses messages, but is there a way I can get them in other languages (in particular in German)? How would I achieve this? I wasn't able to find anything about in the Mailchimp docs. I wouldn't like to translate them myself...

  • Oracle RightNow CX for Good Customer Experiences

    - by Andreea Vaduva
    Oracle RightNow CX is all about the customer experience, it’s about understanding what drives a good interaction and it’s about delivering a solution which works for our customers and by extension, their customers. One of the early guiding principles of Oracle RightNow was an 8-point strategy to providing good customer experiences. Establish a knowledge foundation Empowering the customer Empower employees Offer multi-channel choice Listen to the customer Design seamless experiences Engage proactively Measure and improve continuously The application suite provides all of the tools necessary to deliver a rewarding, repeatable and measurable relationship between business and customer. The Knowledge Authoring tool provides gap analysis, WYSIWIG editing (and includes HTML rich content for non-developers), multi-level categorisation, permission based publishing and Web self-service publishing. Oracle RightNow Customer Portal, is a complete web application framework that enables businesses to control their own end-user page branding experience, which in turn will allow customers to self-serve. The Contact Centre Experience Designer builds a combination of workspaces, agent scripting and guided assistances into a Desktop Workflow. These present an agent with the tools they need, at the time they need them, providing even the newest and least experienced advisors with consistently accurate and efficient information, whilst guiding them through the complexities of internal business processes. Oracle RightNow provides access points for customers to feedback about specific knowledge articles or about the support site in general. The system will generate ‘incidents’ based on the scoring of the comments submitted. This makes it easy to view and respond to customer feedback. It is vital, more now than ever, not to under-estimate the power of the social web – Facebook, Twitter, YouTube – they have the ability to cause untold amounts of damage to businesses with a single post – witness musician Dave Carroll and his protest song on YouTube, posted in response to poor customer services from an American airline. The first day saw 150,000 views and is currently at 12,011,375. The Times reported that within 4 days of the post, the airline’s stock price fell by 10 percent, which represented a cost to shareholders of $180 million dollars. It is a universally acknowledged fact, that when customers are unhappy, they will not come back, and, generally speaking, it only takes one bad experience to lose a customer. The idea that customer loyalty can be regained by using social media channels was the subject of a 2011 Survey commissioned by RightNow and conducted by Harris Interactive. The survey discovered that 68% of customers who posted a negative review about a holiday on a social networking site received a response from the business. It further found that 33% subsequently posted a positive review and 34% removed the original negative review. Cloud Monitor provides the perfect mechanism for seeing what is being said about a business on public Facebook pages, Twitter or YouTube posts; it allows agents to respond proactively – either by creating an Oracle RightNow incident or by using the same channel as the original post. This leaves step 8 – Measuring and Improving: How does a business know whether it’s doing the right thing? How does it know if its customers are happy? How does it know if its staff are being productive? How does it know if its staff are being effective? Cue Oracle RightNow Analytics – fully integrated across the entire platform – Service, Marketing and Sales – there are in excess of 800 standard reports. If this were not enough, a large proportion of the database has been made available via the administration console, allowing users without any prior database experience to write their own reports, format them and schedule them for e-mail delivery to a distribution list. It handles the complexities of table joins, and allows for the manipulation of data with ease. Oracle RightNow believes strongly in the customer owning their solution, and to provide the best foundation for success, Oracle University can give you the RightNow knowledge and skills you need. This is a selection of the courses offered: RightNow Customer Service Administration Rel 12.02 (3 days) Available as In Class and Live Virtual Class (Release 11.11 is available as In Class, Live Virtual Class and Training On Demand) This course familiarises users with the tasks and concepts needed to configure and maintain their system.

For more information and course dates please get in contact with your local Oracle University team. On top of the Service components, the suite also provides marketing tools, complex survey creation and tracking and sales functionality. I’m a fan of the application, and I think I’ve made that clear: It’s completely geared up to providing customers with support at point of need. It can be configured to meet even the most stringent of business requirements. Oracle RightNow is passionate about, and committed to, providing the best customer experience possible. Oracle RightNow CX is the application that makes it possible. About the Author: Sarah Anderson worked for RightNow for 4 years in both in both a consulting and training delivery capacity. She is now a Senior Instructor with Oracle University, delivering the following Oracle RightNow courses: RightNow Customer Service Administration RightNow Analytics RightNow Customer Portal Designer and Contact Center Experience Designer Administration RightNow Marketing and Feedback

  • Good PHP BOOKS for starters!

    - by Goma
    I started reading some PHP books. Most of them in their introduction say that this book , unlike other books, it follows a good habits and practices. Now, I do not know which book tells the truth, and which writer is the most experienced in PHP. These are the books that I had a quick look to their first chapter: PHP and MySQL Web Development (Developer's Library) by Luke Welling and Laura Thomson. Build Your Own Database Driven Web Site Using PHP & MySQL by Kevin Yank. PHP and MySQL for Dummies by Janet Valade. Now, it's your time to advise me and tell me about the excellent one that follows best practices, please give an advice from your experience. (It could be any other book!). Regards,

  • Update from Ola Hallengren: Target multiple devices during SQL Server backup

    - by Greg Low
    Ola has produced another update of his database management scripts. If you haven't taken a look at them, you should. At the very least, they'll give you good ideas about what to implement and how others have done so. The latest update allows targeting multiple devices during backup. This is available in native SQL Server backup and can be helpful with very large databases. Ola's scripts now support it as well.Details are here: http://ola.hallengren.com/sql-server-backup.html http://ola.hallengren.com/versions.html The following example shows it backing up to 4 files on 4 drives, one file on each drive:EXECUTE dbo.DatabaseBackup@Databases = 'USER_DATABASES',@Directory = 'C:\Backup, D:\Backup, E:\Backup, F:\Backup',@BackupType = 'FULL',@Compress = 'Y',@NumberOfFiles = 4And this example shows backing up to 16 files on 4 drives, 4 files on each drive: EXECUTE dbo.DatabaseBackup@Databases = 'USER_DATABASES',@Directory = 'C:\Backup, D:\Backup, E:\Backup, F:\Backup',@BackupType = 'FULL',@Compress = 'Y',@NumberOfFiles = 16Ola mentioned that you can now back up to up to 64 drives.

Hear directly from customer experts and executives from SolarWorld Industries America, British Telecom and Rittman Mead and get your questions answered live by product experts. Register for this complimentary webcast today and join in the discussion tomorrow. Author: Irem Radzik, Senior Principal Product Director, Oracle Organizations that want to use IT as a strategic point of differentiation prefer Oracle’s complete application offering to drive better business performance and optimize their IT investments. These enterprise applications are in the center of business operations and they contain critical data that needs to be accessed continuously, as well as analyzed and acted upon in a timely manner. These systems also need to operate with high-performance and availability, which means analytical functions should not degrade applications performance, and even system maintenance and upgrades should not interrupt availability. Oracle’s data integration products, Oracle Data Integrator, Oracle GoldenGate, and Oracle Enterprise Data Quality, provide the core foundation for bringing data from various business-critical systems to gain a broader, unified view. As a more advance offering to 3rd party products, Oracle’s data integration products facilitate real-time reporting for Oracle Applications without impacting application performance, and provide ability to upgrade and maintain the system without taking downtime. Oracle GoldenGate is certified for Oracle Applications, including E-Business Suite, Siebel CRM, PeopleSoft, and JD Edwards, for moving transactional data in real-time to a dedicated operational reporting environment. This solution allows the app users to offload the resource-heavy queries to the reporting instance(s), reducing CPU utilization, improving OLTP performance, and extending the lifetime of existing IT assets. In addition, having a dedicated reporting instance with up-to-the-second transactional data allows optimizing the reporting environment and even decreasing costs as GoldenGate can move only the required data from expensive mainframe environments to cost-efficient open system platforms.  With real-time data replication capabilities GoldenGate is also certified to enable application upgrades and database/hardware/OS migration without impacting business operations. GoldenGate is certified for Siebel CRM, Communications Billing and Revenue Management and JD Edwards for supporting zero downtime upgrades to the latest app version. GoldenGate synchronizes a parallel, upgraded system with the old version in real time, thus enables continuous operations during the process. Oracle GoldenGate is also certified for minimal downtime database migrations for Oracle E-Business Suite and other key applications. GoldenGate’s solution also minimizes the risk by offering a failback option after the switchover to the new environment. Furthermore, Oracle GoldenGate’s bidirectional active-active data replication is certified for Oracle ATG Web Commerce to enable geographically load balancing and high availability for ATG customers. For enabling better business insight, Oracle Data Integration products power Oracle BI Applications with high performance bulk and real-time data integration. Oracle Data Integrator (ODI) is embedded in Oracle BI Applications version 11.1.1.7.1 and helps to integrate data end-to-end across the full BI Applications architecture, supporting capabilities such as data-lineage, which helps business users identify report-to-source capabilities. ODI is integrated with Oracle GoldenGate and provides Oracle BI Applications customers the option to use real-time transactional data in analytics, and do so non-intrusively. By using Oracle GoldenGate with the latest release of Oracle BI Applications, organizations not only leverage fresh data in analytics, but also eliminate the need for an ETL batch window and minimize the impact on OLTP systems. You can learn more about Oracle Data Integration products latest 12c version in our upcoming launch webcast and access the app-specific free resources in the new Data Integration for Oracle Applications Resource Center.

  • AlwaysOn Architecture Guide: Building a High Availability and Disaster Recovery Solution by Using AlwaysOn Availability Groups

    SQL Server 2012 AlwaysOn Availability Groups provides a unified high availability and disaster recovery (HADR) solution that improves upon legacy functionality previously found across disparate features. Prior to SQL Server 2012, several customers used database mirroring to provide local high availability within a data center, and log shipping for disaster recovery across a remote data center. With SQL Server 2012, this common design pattern can be replaced with an architecture that uses availability groups for both high availability and disaster recovery. This paper details the key topology requirements of this specific design pattern, including quorum configuration considerations, steps required to build the environment, and a workflow that shows how to handle a disaster recovery event in the new topology.

  • Should I add old code into my repository?

    - by Ben Brocka
    I've got an SVN repository of a PHP site and the last programmer didn't use source control properly. As a result, only code since I started working here is in the Repo. I have a bunch of old copies of the full code base saved in files as "backups" but they're not in source control. I don't know why most of the copies were saved nor do I have any reasonable way to tag them to a version number. Due to upgrades to the frameworks and database drivers involved, the old code is quite defunct; it no longer works on the current server config. However, the previous programmers had some...unique...logic, so I hate to be completely without old copies to refer to what on earth they were doing. Should I keep this stuff in version control? How? Wall off the old code in separate Tags/branches?

  • Shifting from no-www to www and browsers' password storage

    - by user1444680
    I created a website having user-registration system and invited my friend to join it. I gave him the link of no-www version: http://mydomain.com but now after reading this and this, I want to shift to www.mydomain.com. But there's a problem. I saw that my browser is storing separate passwords for mydomain.com and www.mydomain.com. So in my friend's browser his password must have been stored for no-www. That means after I shift to www and next time he opens the login page, his browser wouldn't auto-fill the username and password fields and there will also be an extra entry (of no-www) in his browser's database of stored passwords. Can this be avoided? Can I do something that will convey to browsers that www.mydomain.com and mydomain.com are the same website? I already have a CNAME record for www pointing to mydomain.com but it seems that search engines consider CNAME as alias but browsers consider them as different websites, I don't know why.
