• ClearTrace Supports SQL Server 2008 R2

  - by Bill Graziano

  It was a long time coming and I hope worth the wait.  If you have SQL Server 2008 R2 installed on the same box as ClearTrace and you download the latest ClearTrace build (36) you’ll be able to read SQL Server 2008 R2 traces.  I also fixed a bug handling very, very large SQL statements.  I encountered an INSERT statement that was 12MB in size.  It was storing XML in a database.  ClearTrace uses regular expressions to clean up the SQL it finds.  Running two dozen regular expressions over this 12MB string caused the application to crash.  In this build I’m just skipping any statement over 1MB.  I’ll do something a little nicer in the next build. (And if you don’t want to download ClearTrace you can test the online version at www.TraceTune.com)

• Hybrid Columnar Compression

  - by user12620172

  You heard me in the past talk about the HCC feature for Oracle databases. Hybrid Columnar Compression is a fantastic, built-in, free feature of Oracle 11Gr2. One used to need an Exadata to make use of it. However, last October, Oracle opened it up and now allows it to work on ANY Oracle DB server running 11Gr2, as long as the storage behind it is a ZFSSA for DNFS, or an Axiom for FC. If you're not sure why this is so cool or what HCC can do for your Oracle database, please check out this presentation. In it, Art will explain HCC, show you what it does, and give you a great idea why it's such a game-changer for those holding lots of historical DB data. Did I mention it's free?

• Is there a program to manage movies and TV shows that supports mp4 tags?

  - by root45

  I'm looking for a media manager that will display and play movies and TV shows and will read data included in mp4 and m4v files. So far I've looked at XBMC, Moovida and Boxee and all of these seem to keep their own separate database or XML files for reading and storing tag information. I also looked at Banshee because of this answer, but it didn't read my tags. Banshee is also geared towards music videos instead of actual movies and TV shows. So I'm looking for software that Displays and plays movies and TV Shows Reads mp4 and m4v tags Preferably something with bulk import (i.e., I don't want to add 1,000 items to a new library) Bonus if it also has a tag editor Bonus if it's an XBMC extension

• How can I designed multi-threaded application for larger user base

  - by rokonoid

  Here's my scenario, I need to develop a scalable application. My user base may be over 100K, every user has 10 or more small tasks. Tasks check every minute with a third party application through web services, retrieving data which is written in the database, then the data is forwarded to it's original destination. So here's the processing of a small task: while(true){ Boolean isNewInformationAvailable = checkWhetherInformationIsAvailableOrNot(); If(isNewInformationAvailable ==true){ fetchTheData(); writeToDatabase(); findTheDestination(); deliverTheData(); isAvailable =false; } } Here is the question: as the application is large, how should I approach designing this. I'm going to use Java to write it. Should I use concurrency, and how would you manage the concurrency?

• Pending and Approval process

  - by zen

  So let's say I have a DB table with 8 columns, one is a unique auto-incrementing used as ID. So I have a page that pulls in the info for each row based on query string ID. I want to give my users the ability to propose changes. Kinda like a wiki setup. So I was thinking I should just have another duplicate table or maybe database altogether (without the auto-incrementing column and maybe with a date edited column) that keeps all proposed changes in queue and then when I approve them, the script can move the row from the proposed DB to the real DB. Does this sound good or is there a better process for this?

• Adding multiplayer to an HTML5 game

  - by espais

  I am interested in making a game that I currently have a co-op experience, however I'm curious as to the best method of implementing this in HTML5. I have made games before using straight C sockets, and also with the Net library for SDL. What are some of my best options for doing this in a canvas-based environment? At present, all I can come up with are either AJAX/database solutions (with a high refresh rate), or somehow implementing a PHP server that would funnel the data through sockets. The overall gameplay would be a 2.5D platformer-ish type of game, so both clients would need to be continually updated with player positions, enemy positions, projectiles, environmental data, etc.

• Cloud Sample Code on OTN

  - by Oliver Steinmeier

  In recent months our blog has covered many aspects of the overall Oracle Cloud platform, whether it's PaaS (Java Cloud Service, Database Cloud Service) or SaaS (Sales Cloud Application Composer). Teams within Oracle have been busy building demos and proof-of-concept applications using the same technologies, and we have now started posting some of these as code samples on the Oracle Technology Network (OTN).  The zip files include both the source code and helpful information to get you started using the code.  Everything is covered under a BSD license.  In future blog posts we will dive deeper into some of these applications. Do you have any ideas or requests for sample code you would like us to create to help you with your work?  Hit the comments and let us know!

• Is it possible to work with a dedicated server in XNA?

  - by Jake

  Hi I want to release my XNA game to the XBOX platform, but I'm worried about the networking limitations. Basically, I want to have a dedicated (authoritative) server, but it sounds like that is not possible. Which is why I'm wondering about: Using port 80 web calls to php-driven database Using an xbox as a master-server (is that possible?) I like the sound of #1, because I could write my own application to run on the xbox, and I would assume other users could connect to it similar to the p2p architecture. Anyone able to expand on theory #2 above? or #1 as worst-case scenario?

• How can I set up private, per-user sections on Joomla?

  - by Michael Paulukonis

  For this weekend's GiveCamp project, my team has been tasked with adding some functionality to an existing Joomla-powered website for a non-profit. A certain type of user will login, and have access to a personal area where they can upload files, check for messages, see tasks that have been assigned, etc. Each user would have their own area. They would not be creating pages, and their information would only be visible to themselves (or a site-administrator, of course. No sort of weird HIPAA privacy involved). None of us have worked with Joomla before, but we'd like to help this non-profit. We're not sure if we're searching using the wrong terms, or if we're just not finding it. Is such a solution possible in Joomla? And/or are we better off building some standalone solution that interfaces with the same mySQL database as Joomla?

• How can I keep track of a battle log on a web game?

  - by Jay W

  Recently I started working on a Web turn-based PvP RPG game. Now I'm working on the battle system but I encountered some issues: How can I keep track of everything that happens in the battle? It should keep track of the characters on the field, inventory, the damage done etc. I first thought I would simply put it in the (MySQL) database, but I think it will be too much. Especially if several people are in a battle. I thought of puting this in sessions or cookies but I don't think thats reliable. Does anyone have an idea how I can do this?

• Problem on application with asp in IIS 7.5 with oracle 11g

  - by Hichem

  We have an application developed with .Net on server 2008 R2 and IIS 7.5 wich is linked liked to oracle 11g on another server. Our problem is that we lose the service every two or three or more. The application stops and we have to restart IIS or the server to continue the job (the number of users is less then 50). We have no error message. Do you know anything to do to avoid this situation, something like: A parameter to put on asp pages A parameter to switch on or off on the server or on the database

• How to organize my 1000s of PDF?

  - by mmb

  I have a huge collection of PDF. Mostly it consists of research papers, of self-created documents but also of scanned documents. Right now I drop them all in one folder and give them precise names with tags in the filename. But even that gets impractical, so I am looking for a PDF library management application. I am thinking of something like Yep for Mac, with the following features: PDF cover browsing (with large preview, larger than Nautilus allows) tagging of PDF (data should be readable cross-platform) possibility to share across network (thus rather flat files than database) if possible: cross-platform Mendeley seemed to be a good choice, but I am not only having academic papers and don't want to fill it all metadata that is required there. The only alternative I could find thus far is Shoka, but the features are limited and developments seems to have stopped already.

• Getting Started with Hashing in SQL Server

  Encryption brings data into a state which cannot be interpreted by anyone who does not have access to the decryption key, password, or certificates. Hashing brings a string of characters of arbitrary size into a usually shorter fixed-length value or key. Here's how to get started using it.

• Stairway to T-SQL DML Level 4: The Mathematics of SQL: Part 1

  A relational database contains tables that relate to each other by key values. When querying data from these related tables you may choose to select data from a single table or many tables. If you select data from many tables, you normally join those tables together using specified join criteria. The concepts of selecting data from tables and joining tables together is all about managing and manipulating sets of data. In Level 4 of this Stairway we will explore the concepts of set theory and mathematical operators to join, merge, and return data from multiple SQL Server tables. Get Smart with SQL Backup Pro Powerful centralised management, encryption and more.SQL Backup Pro was the smartest kid at school Discover why.

• Using packages (gems, eggs, etc.) to create decoupled architectures

  - by Juan Carlos Coto

  The main issue Seeing the good support most modern programming platforms have for package management (think gem, npm, pip, etc), does it make sense to design an application or system be composed of internally developed packages, so as to promote and create a loosely coupled architecture? Example An example of this would be to create packages for database access, as well as for authentication and other components of the system. These, of course, use external packages as well. Then, your system imports and uses these packages - instead of including their code within its own code base. Considerations To me, it seems that this would promote code decoupling and help maintainability, almost in a Web-based-vs.-desktop-application kind of way (updates are applied almost automatically, single code base for single functionality, etc.). Does this seem like a rational and sane design concept? Is this actually used as a standard way of structuring applications today? Thanks very much!

• shotwell does not copy, but import them without copying

  - by user65764

  I tryed to import photos from my external harddisk into shotwell. After doing this, I disconected the harddisk and the photos disapeared immediately. I saw that the photos had been importet into the database without being copied. Copying the whole file into the picturefile is possible, but I would like to have to same fileorder in my library. Not a mixed up (organised by date (shotwell) and organised by filenames (my old organisation). It has not been any problem copying photos from a dvd. Is there any possibility to have the same filestructure for all fotos or is there a bug in shotwell? Thanks

• Yes to NoSQL

  There seems to be some backlash building up against NoSQL with posts like Ted Dziuba I Can't Wait for NoSQL to Die or Dennis Forbes The Impact of SSDs on Database Performance and the Performance Paradox of Data Explodification (aka Fighting the NoSQL mindset). These are interesting articles to read and yes RDBMSs are not going the way of the dodo yet (I even said that in The RDBMS is dead, which by the way, was written before NoSQL was coined, but I digress ). Nevertheless,...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.
