• Thoughts on Nexus in SQL Server PDW

  - by jamiet

  I have been on a SQL Server Parallel Data Warehouse (aka PDW) training course this week and was interested to learn that you can't (yet) use SQL Server Management Studio (SSMS) against PDW, instead they ship a 3rd party tool called Nexus Chameleon. This was a bit of a disappointment at the beginning of the week (I'd prefer parity across SQL Server editions) but actually, having used Nexus for 3 days, I'm rather getting used to it. Some of it is a bit clunky (e.g. everything goes via an ODBC DSN) but once you get into using it its the epitome of "it just works". For example, over the past few years I have come to rely on intellisense in SSMS and have learnt to cope with its nuances. There is no intellisense in Nexus but you know what....I don't really miss it that much. In a sense its a breath of fresh air not having to hope that you've crossed the line into that will it work/won't it work grey area with SSMS intellisense. And I don't end up with writing @@CONNECTIONS instead of FROM anymore (anyone else suffer from this?) :) Moreover, Nexus is a standalone tool. Its not a bunch of features shoehorned into something else (Visual Studio). Another thing I like about Nexus is that you can actually do something with your resultset client-side. Take a look at the screenshots below:   You can see Nexus allows you to group a resultest by a column or set of columns. Nice touch. I know that many people have submitted Connect requests asking for the ability to do similar things in SSMS that would mean we don't have to copy resultsets into Excel (I know I have) - Nexus is a step in that direction. Its refreshing to use a tool that just gets out of the way yet still has some really useful features. How ironic that it gets shipped inside an edition of SQL Server! If I had the option of using Nexus in my day job I suspect that over time I would probably gravitate back to SSMS because as yet I haven’t really stretched Nexus’ capabilities, overall SSMS *does* have more features and up until now I've never really had any objections to it ... but its been an interesting awakening into the nuances that plague SSMS. Anyone else used Nexus? Any thoughts on it? @Jamiet

• Workaround: XNA 4 importing only part of 3d model from FBX

  - by Vitus

  Recently I found a problem with importing 3D models from FBX files: it sometimes imported partly. That is when you draw a 3D model, loaded from FBX file, processed by content pipeline, you got only part of meshes. “Sometimes” means that you got this error only for some files. Results of my research below. For example, I have 10Mb binary FBX file with a model, looks like: And when I load it, result Model instance contains only part of meshes and looks like: Because models from other files imported normally, I think that it’s a “bad format” file. When you add FBX file to your XNA Content project and build it, imported file processing by XNA Fbx Importer & Processor. On MSDN I found that FbxImporter designed to work with 2006.11 version of FBX format. My file is FBX 2012 format. Ok, I need to convert it to 2006 format. It can be done by using Autodesk FBX Converter 2012.1. I tried to convert it to other versions of FBX formats, but without success. And I also tried to import my FBX file to 3D MAX, and it imported correctly. Then I export model using 3D MAX, and it generate me other FBX, which I add to my XNA project. After that I got full model, that rendered well! So, internal data structure of FBX file is more important for right XNA import, than it version! Unfortunately, Autodesk FBX is not an open file format. If you want to work with FBX, you should use Autodesk FBX SDK. This way you can manually read content of FBX file, and use it everyway. Then I tried to convert my source FBX file to DAE Collada, and result DAE file back to FBX, using FBX Converter (FBX –> DAE –> FBX). The result FBX file can be imported normally.   Conclusion: XNA FbxImporter correct work doesn't depend on version (2006, 2011, etc) and form (binary, ascii) of FBX file. Internal FBX data structure much more important. To make FBX "readable" for XNA Importer you can use double conversion like FBX -> Collada -> FBX You also can use FBX SDK to manually load data from FBX P.S. Autodesk FBX Converter 2012 is more, than simple converter. It provide you tools like: FBX Explorer, which show you structure of FBX file; FBX Viewer, which render content of FBX and provide basic intercation like model move and zoom; FBX Take Manager, which allow to work with embedded animations

• Am I experienced enough to learn and develop immediately using Ruby on Rails?

  - by acheong87

  General Question I understand that discussions revolving around questions of this form run the risk of becoming too specific to help others. So, perhaps a better, general question would be: What kind of experience, if any, translates easily to Ruby on Rails; and if none, then what's the learning curve like, in comparison to other popular languages? Background I have the opportunity to build a website using whatever technologies I wish to use. It's a fairly simple website, for listing products, taking payments, managing customer data, providing a back-end portal for employees to manage data, possibly hooking in flight information (the products are travel related), possibly integrating a blog and all the social-networking goodies. Specific Problem I have to let the client know by tonight whether I'm interested in taking up this project, before he talks to other potential developers, but I'm on the fence. I already work a full-time C++ development job, so the money doesn't do it for me. It's the opportunity to (be paid to) learn some new technologies and to have a real, running product in the end. I've heard and read great things about Ruby, and am really intrigued. I zipped through some introductory Ruby tutorials, no sweat. However I found the Rails tutorials a little overwhelming, especially not being able to try it out anywhere. And researching Rails hosts like Heroku and EngineYard makes me think that maybe I don't know what I'm getting myself into. The ship's leaving port! I wish I had more time to learn, better yet play with the language, but I have to decide soon! Should I venture or pass? Additional Details My experiences are in C/C++/Tcl/Perl/PHP/jQuery, and basic knowledge of Java/C#. I didn't study C.S. formally so I wasn't exposed to design principles, programming paradigms, etc., which is my greatest concern. Will my lack of understanding in this realm make RoR frustrating to learn? Will it be so incompatible with a C++ "way" of thinking that I'll wish I never started? Am I putting my client at risk by attempting this? If it helps, I'm quick to learn new things (self-taught so far) and care a great deal about correctness, using things for their intended purposes, and so on. I've read numerous recommendations of Agile Development with Rails and would love to read it (though perhaps, while developing in parallel, for shortness of time). Worse comes to worst, I'd give up and do the standard LAMP gig, of course, not charging the client for wasted time. But I'm hoping to avoid the project altogether if it's gonna come down to that! Thanks in advance for any tips, insights, votes of confidence, votes of discouragement (for the better), and such.

• Travelling MVP #3: Community event in Varna, Bulgaria

  - by DigiMortal

  Second stop in my DevReach 2012 trip was at Varna. We had not much time to hang around there but this problem will get fixed next year if not before. But still we had sessions there with Dimitar Georgijev and I had also chance to meet local techies. Next time we will have more tech and beers for sure! We started in the morning from Bucharest and travelled through Ruse, Razgrad and Shumen to Varna. It’s about 275km. We used cab, local bus and Dimitar father’s car. We had one food stop in Ruse and after that we went directly to Varna. Here is our route on map. Varna is Bulgarian city that locates on western coast of Black Sea. I have been there once before this trip and it’s good place to have vacation under sun. Also autumn is there milder than here in Estonia (third day of snow is going on). Bulgaria has some good beers, my favorite mankind killer called rakia and very good national cuisine. Food is made of fresh stuff and it is damn good experience. Here are some arbitrarily selected images (you can click on these to view at original size): Old bus “monument” in Razgrad Stuffed peppers, Bulgarian national cuisine Infra-red community having good time and beers We made our sessions at one study class of Varna technical university. It’s a little bit old style university but everything we needed was there and we had no problems with machinery. Sessions were same as in Bucharest. The user group in Varna is brand new and hopefully it will be something bigger one good day. At least I try to make my commits so they get on their feet quicker. As we had not much time to announce the event there was about 15 guys listening to us and I’m happy that it was not too much hyped event because still I was getting my first experiences with foreign audiences. After sessions we took our stuff to hotel and went to hang around with local techies. We had some good time there and made some new friends. Next time when I go to Varna I go back as more experienced speaker and I plan to do there one tougher and highly challenging session. Maybe somebody from Estonian community will join me and then it will be well planned surprise-attack to Varna :)

• Be Careful When Referencing SPList.Items

  - by Brian Jackett

  Be very careful how you reference your SPListItem objects through the SharePoint API.  I’ll say it again.  Be very careful how you reference your SPListItem objects through the SharePoint API.  Ok, now that you get the point that this will be a “learn from my mistakes and don’t do unsmart things like I did” post, let’s dig into what it was that I did poorly. Scenario     For the past year I’ve been building custom .Net applications that are hosted through SharePoint.  These application involve a number of SharePoint lists, external databases, custom web parts, and other SharePoint elements to provide functionality.  About two weeks ago I received a message from one of our end users that a custom application was performing slowly.  Specifically performance was slow when users were performing actions that interacted with the primary SharePoint list storing data for that app. The Problem     I took a copy of the production site into a dev environment to investigate the code that was executing.  After attaching the debugger and running through the code I quickly found pieces of code referencing SPListItem objects (like below) that were performing very poorly: SPListItem myItem = SPContext.Current.Web.Lists["List Name"].Items.GetItemById(value); // do updates on SPListItem retrieved     As it turns out the SPList I was referencing was fairly large at ~1000 items and weighing in over 150 MB.  You see the problem with my above code is that I retrieved the SPListItem by first (unnecessarily) going through the Items member of the list.  As I understand it, when doing so the executing code will attempt to resolve that entity and pull it from the database and into RAM (all 150 MB.)  This causes the equivalent of a 50 car pile up in terms of performance with a single update taking more than 15 seconds. The Solution     The solution is actually quite simple and I wish I had realized this during development.  Instead of going through the Items member it is possible to call GetItemById(…) directly on the SPList as in the example below: SPListItem myItem = SPContext.Current.Web.Lists["List Name"].GetItemById(value); // do updates on SPListItem retrieved     After making this simple change performance skyrocketed and updates were back to less than a second.   Conclusion     When given the option between two solutions, usually the simplest is the best solution.  In my scenario I was adding extra complexity going through the API the long way around to get to the objects I needed and it ended up hurting performance greatly.  Luckily we were able to find and resolve the performance issue in a relatively short amount of time.  Like I said at the beginning of the post, learn from my mistakes and hope it helps you.         -Frog Out   Image linked from http://www.freespirit.com/files/IMAGE/COVER/LARGE/BeCarefulSafe.jpg

• Detecting if someone is in a room in your house and sending you an email.

  - by mbcrump

  Let me setup this scenario: You are selling your house. You have small children. (Possibly 2 rug rats or more) The real estate company calls and says they have a showing for your house between the hours of 3pm-6pm. You have to keep the children occupied. You realize this is the 5th time you have shown your house this week. What is a programmer to do?……Setup a webcam, find a motion detection software that has support to launch a program and of course, Visual Studio 2010. First, comes the tools Some sort of webcam, I chose the WinBook because a friend of mine loaned it to me. It is a basic USB2.0 camera that supports 640x480 without software.  Next up was find webcam software that supports launching a program. WebcamXP support this. VS 2010 Console Application. A cell phone that you can check your email. You may be asking, why write code to send the email when a lot of commercial software motion detection packages include that as base functionality. Well, first it cost money and second I don’t want the picture of the person as that probably invades privacy and as a future buyer, I don’t want someone recording me in their house. Now onto the show... First, the code part. We are going to create a VS2010 or whatever version you have installed and use the following code snippet. Code Snippet using System; using System.Net.Mail; using System.Net;     namespace MotionDetectionEmailer {     class Program     {         static void Main(string[] args)         {             try             {                 MailMessage m = new MailMessage                    ("[email protected]",                     "[email protected]",                     "Motion Detected at " + DateTime.Now,                     "Someone is in the downstairs basement.");                 SmtpClient client = new SmtpClient("smtp.charter.net");                 client.Credentials = new NetworkCredential("mbcrump", "NOTTELLINGYOU");                 client.Send(m);             }               catch (SmtpException ex)             {                 Console.WriteLine("Who cares?? " + ex.ToString());             }         }       } } Second, Download and install wecamxp and select the option to launch an external program and you are finished. Now, when you are at MCDonalds and can check your email on your phone, you will see when they entered the house and you can go back home without waiting the full 3 hours. --- NICE!

• How to Disable the New Geolocation Feature in Google Chrome

  - by Asian Angel

  The latest release of Google Chrome has geolocation enabled by default, and if you are worried about privacy or just don’t want websites to prompt you for your location, we’ve got the quick details on how to turn it off. Readers should note that the new Geolocation feature doesn’t give out your details by default, so don’t panic. It’s also only active, at the time of this writing, in the Dev channel builds of Chrome—so if you are using the regular stable build this feature won’t arrive for a while anyway. Note: If you’re a Firefox user, be sure to check out our guide to disabling geolocation in Firefox 3.x. What’s this Geolocation Feature About? Geolocation is a way for your browser to tell a website about your physical location, so you can get results tailored to where you actually are—for example, if you visited Google Maps it can ask you for your location to give you an accurate picture of where you are. To use this feature in Google Maps, you would click on the small white icon to activate the feature. As soon as you have clicked on the small white icon, a thin green toolbar will appear at the top of the webpage, asking to Allow or Deny.   How to Turn Chrome’s Geolocation Off If you want to turn geolocation off you will need to open the “Chrome Options Window”, navigate to the third tab, and click on the “Content settings… ” button. When the “Content Settings Window” opens go to the “Location Tab” and select “Do not allow any site to track my physical location”. Once that is done close out the “Content Settings & Chrome Options Windows”. When you go back to Google Maps and try using the small white icon again this is the message that you will see at the top of the page. Now that is much better! If you are unhappy with geolocation being enabled by default in the latest Dev Channel release then this will help get the problem sorted out nicely.

• SQL Server 2008 Compression

  - by Peter Larsson

  Hi! Today I am going to talk about compression in SQL Server 2008. The data warehouse I currently design and develop holds historical data back to 1973. The data warehouse will have an other blog post laster due to it's complexity. However, the server has 60GB of memory (of which 48 is dedicated to SQL Server service), so all data didn't fit in memory and the SAN is not the fastest one around. So I decided to give compression a go, since we use Enterprise Edition anyway. This is the code I use to compress all tables with PAGE compression. DECLARE @SQL VARCHAR(MAX)   DECLARE curTables CURSOR FOR             SELECT 'ALTER TABLE ' + QUOTENAME(OBJECT_SCHEMA_NAME(object_id))                     + '.' + QUOTENAME(OBJECT_NAME(object_id))                     + ' REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = PAGE)'             FROM    sys.tables   OPEN    curTables   FETCH   NEXT FROM    curTables INTO    @SQL   WHILE @@FETCH_STATUS = 0     BEGIN         IF @SQL IS NOT NULL             RAISERROR(@SQL, 10, 1) WITH NOWAIT           FETCH   NEXT         FROM    curTables         INTO    @SQL     END   CLOSE       curTables DEALLOCATE  curTables Copy and paste the result to a new code window and execute the statements. One thing I noticed when doing this, is that the database grows with the same size as the table. If the database cannot grow this size, the operation fails. For me, I first ended up with orphaned connection. Not good. And this is the code I use to create the index compression statements DECLARE @SQL VARCHAR(MAX)   DECLARE curIndexes CURSOR FOR             SELECT      'ALTER INDEX ' + QUOTENAME(name)                         + ' ON '                         + QUOTENAME(OBJECT_SCHEMA_NAME(object_id))                         + '.'                         + QUOTENAME(OBJECT_NAME(object_id))                         + ' REBUILD PARTITION = ALL WITH (FILLFACTOR = 100, DATA_COMPRESSION = PAGE)'             FROM        sys.indexes             WHERE       OBJECTPROPERTY(object_id, 'IsMSShipped') = 0                         AND OBJECTPROPERTY(object_id, 'IsTable') = 1             ORDER BY    CASE type_desc                             WHEN 'CLUSTERED' THEN 1                             ELSE 2                         END   OPEN    curIndexes   FETCH   NEXT FROM    curIndexes INTO    @SQL   WHILE @@FETCH_STATUS = 0     BEGIN         IF @SQL IS NOT NULL             RAISERROR(@SQL, 10, 1) WITH NOWAIT           FETCH   NEXT         FROM    curIndexes         INTO    @SQL     END   CLOSE       curIndexes DEALLOCATE  curIndexes When this was done, I noticed that the 90GB database now only was 17GB. And most important, complete database now could reside in memory! After this I took care of the administrative tasks, backups. Here I copied the code from Management Studio because I didn't want to give too much time for this. The code looks like (notice the compression option). BACKUP DATABASE [Yoda] TO              DISK = N'D:\Fileshare\Backup\Yoda.bak' WITH            NOFORMAT,                 INIT,                 NAME = N'Yoda - Full Database Backup',                 SKIP,                 NOREWIND,                 NOUNLOAD,                 COMPRESSION,                 STATS = 10,                 CHECKSUM GO   DECLARE @BackupSetID INT   SELECT  @BackupSetID = Position FROM    msdb..backupset WHERE   database_name = N'Yoda'         AND backup_set_id =(SELECT MAX(backup_set_id) FROM msdb..backupset WHERE database_name = N'Yoda')   IF @BackupSetID IS NULL     RAISERROR(N'Verify failed. Backup information for database ''Yoda'' not found.', 16, 1)   RESTORE VERIFYONLY FROM    DISK = N'D:\Fileshare\Backup\Yoda.bak' WITH    FILE = @BackupSetID,         NOUNLOAD,         NOREWIND GO After running the backup, the file size was even more reduced due to the zip-like compression algorithm used in SQL Server 2008. The file size? Only 9 GB. //Peso

• Interviews: Going Beyond the Technical Quiz

  - by Tony Davis

  All developers will be familiar with the basic format of a technical interview. After a bout of CV-trawling to gauge basic experience, strengths and weaknesses, the interview turns technical. The whiteboard takes center stage and the challenge is set to design a function or query, or solve what on the face of it might seem a disarmingly simple programming puzzle. Most developers will have experienced those few panic-stricken moments, when one’s mind goes as blank as the whiteboard, before un-popping the marker pen, and hopefully one’s mental functions, to work through the problem. It is a way to probe the candidate’s knowledge of basic programming structures and techniques and to challenge their critical thinking. However, these challenges or puzzles, often devised by some of the smartest brains in the development team, have a tendency to become unnecessarily ‘tricksy’. They often seem somewhat academic in nature. While the candidate straight out of IT school might breeze through the construction of a Markov chain, a candidate with bags of practical experience but less in the way of formal training could become nonplussed. Also, a whiteboard and a marker pen make up only a very small part of the toolkit that a programmer will use in everyday work. I remember vividly my first job interview, for a position as technical editor. It went well, but after the usual CV grilling and technical questions, I was only halfway there. Later, they sat me alongside a team of editors, in front of a computer loaded with MS Word and copy of SQL Server Query Analyzer, and my task was to edit a real chapter for a real SQL Server book that they planned to publish, including validating and testing all the code. It was a tough challenge but I came away with a sound knowledge of the sort of work I’d do, and its context. It makes perfect sense, yet my impression is that many organizations don’t do this. Indeed, it is only relatively recently that Red Gate started to move over to this model for developer interviews. Now, instead of, or perhaps in addition to, the whiteboard challenges, the candidate can expect to sit with their prospective team, in front of Visual Studio, loaded with all the useful tools in the developer’s kit (ReSharper and so on) and asked to, for example, analyze and improve a real piece of software. The same principles should apply when interviewing for a database positon. In addition to the usual questions challenging the candidate’s knowledge of such things as b-trees, object permissions, database recovery models, and so on, sit the candidate down with the other database developers or DBAs. Arm them with a copy of Management Studio, and a few other tools, then challenge them to discover the flaws in a stored procedure, and improve its performance. Or present them with a corrupt database and ask them to get the database back online, and discover the cause of the corruption.

• Announcing MySQL Enterprise Backup 3.7.1

  - by Hema Sridharan

  The MySQL Enterprise Backup (MEB) Team is pleased to announce the release of MEB 3.7.1, a maintenance release version that includes bug fixes and enhancements to some of the existing features. The most important feature introduced in this release is Automatic Incremental Backup. The new  argument syntax for the --incremental-base option is introduced which makes it simpler to perform automatic incremental backups. When the options --incremental & --incremental-base=history:last_backup are combined, the mysqlbackup command  uses the metadata in the mysql.backup_history table to determine the LSN to use as the lower limit of the incremental backup. You no longer need to keep track of the actual LSN (as in the option --start-lsn=LSN) or even the location of the previous backup (as in the option --incremental-base=dir:directory_path)This release also incudes various bug fixes related to some options used in MEB. The most important are few of them as listed below,1. The option --force now allows overwriting InnoDB data and log files in  combination with the apply-log and apply-incremental-backup options, and replacing the image file in combination with the backup-to-image and backup-dir-to-image options. 2.

• No HDMI audio in 13.04

  - by King84

  I have just upgraded from 12.10 to 13.04 and now everything works perfectly, except the fact that I have no audio via HDMI. I am using a Samsung tv-monitor connected via HDMI to my video card Asus EAH4670/DI/1GD3 (which has a Radeon HD 4670 gpu on it), installed phisically into my motherboard which is a MSI 770-C45. I am running kernel 3.9, I just have no sound. I tried downloading and installing https://code.launchpad.net/~ubuntu-audio-dev/+archive/alsa-daily/+files/oem-audio-hda-daily-dkms_0.201304261252~raring1_all.deb , but without any good result.

• Access Control Service: Protocol and Token Transition

  - by Your DisplayName here!

  ACS v2 supports a number of protocols (WS-Federation, WS-Trust, OpenId, OAuth 2 / WRAP) and a number of token types (SWT, SAML 1.1/2.0) – see Vittorio’s Infographic here. Some protocols are designed for active client (WS-Trust, OAuth / WRAP) and some are designed for passive clients (WS-Federation, OpenID). One of the most obvious advantages of ACS is that it allows to transition between various protocols and token types. Once example would be using WS-Federation/SAML between your application and ACS to sign in with a Google account. Google is using OpenId and non-SAML tokens, but ACS transitions into WS-Federation and sends back a SAML token. This way you application only needs to understand a single protocol whereas ACS acts as a protocol bridge (see my ACS2 sample here). Another example would be transformation of a SAML token to a SWT. This is achieved by using the WRAP endpoint – you send a SAML token (from a registered identity provider) to ACS, and ACS turns it into a SWT token for the requested relying party, e.g. (using the WrapClient from Thinktecture.IdentityModel): [TestMethod] public void GetClaimsSamlToSwt() {     // get saml token from idp     var samlToken = Helper.GetSamlIdentityTokenForAcs();     // send to ACS for SWT converion     var swtToken = Helper.GetSimpleWebToken(samlToken);     var client = new HttpClient(Constants.BaseUri);     client.SetAccessToken(swtToken, WebClientTokenSchemes.OAuth);     // call REST service with SWT     var response = client.Get("wcf/client");     Assert.AreEqual<HttpStatusCode>(HttpStatusCode.OK, response.StatusCode); } There are more protocol transitions possible – but they are not so obvious. A popular example would be how to call a REST/SOAP service using e.g. a LiveId login. In the next post I will show you how to approach that scenario.

• Oracle WebCenter: Social Networking & Collaboration

  - by kellsey.ruppel(at)oracle.com

  We’ve talked in previous weeks about the key goals of the new release of WebCenter are providing a Modern User Experience, unparalleled Application Integration, converging all the best of the existing portal platforms into WebCenter and delivering a Common User Experience Architecture.  We’ve provided an overview of Oracle WebCenter and discussed some of the other key goals in previous weeks, and this week, we’ll focus on how the new release of Oracle WebCenter provides unprecedented Social Networking and Collaboration.We recently talked with Carin Chan, Principal Product Manager at Oracle, around the topic of Social Networking and Collaboration. In today’s work environment, employees have come to expect social and collaborative services to augment their work environment. Whether it is to post a blog or to poll fellow coworkers, employees expect and demand access to highly integrated, collaborative work environments that allow them to quickly contribute at work -- whether it is to make informed decisions, contribute on projects, or share knowledge.Social and collaborative services from Oracle WebCenter add an immeasurable amount of value to achieving a modern user experience. Oracle WebCenter Services provides rich and comprehensive social computing services that include services such as wikis, blogs, instant messaging, presence, activity streams and graphs, and polls/surveys that offer employees access to rich collaborative services to work efficiently.Employees can create pages or spaces that mix and match collaborative services while bringing in data from other applications to share with groups, teams, or organizations. These out of the box social and collaborative services include: People Connections and Activity Streams enable users to quickly assemble and visualize their social business networks and track user activities.Activity Graphs tracks all user activities in real-time and gathers intelligence about these users, their connections and the way they use information to make educated recommendations and provide on the spot information discovery.Wikis and blogs enable the community authoring of documents and sharing of ideas and also allow for the gathering of feedback and comments on those ideas.Tags and links allow users to easily mark, connect and share information with others.RSS feeds are available to track new or changed information related to discussion forums, processes or activities in an Oracle WebCenter environment.Discussion forums enable sharing of group knowledge and easy creation of communities around specific topics.Announcements allow you to manage and publish important news to your user base.Instant Messaging and Presence enable real-time awareness and communication with available users in the context of a business task.Web and Voice Conferencing enables real-time communication with internal and external business users.Lists provide a way to manage list data directly on the web as well as export and import it from and to Microsoft Excel.Oracle WebCenter Analytics provides comprehensive reporting metrics on activity and content usage within portals or composite applications.Activity Streams allow you to track activities and visualize your business networks.While being able to integrate into your portal deployment, these services are also integrated into how users are already working. This includes integration with software such as Microsoft Outlook, Microsoft Office and mobile devices such as the Apple iPhone. These services are just a tip of the iceberg regarding social and collaborative services that Oracle WebCenter has to offer your employees. Be sure to keep checking back this week for in future posts, we’ll delve deeper into a few of these collaborative services and discuss how a combination of collaborative services offer a better portal deployment to empower business users.

• MySQL and Hadoop Integration - Unlocking New Insight

  - by Mat Keep

  “Big Data” offers the potential for organizations to revolutionize their operations. With the volume of business data doubling every 1.2 years, analysts and business users are discovering very real benefits when integrating and analyzing data from multiple sources, enabling deeper insight into their customers, partners, and business processes. As the world’s most popular open source database, and the most deployed database in the web and cloud, MySQL is a key component of many big data platforms, with Hadoop vendors estimating 80% of deployments are integrated with MySQL. The new Guide to MySQL and Hadoop presents the tools enabling integration between the two data platforms, supporting the data lifecycle from acquisition and organisation to analysis and visualisation / decision, as shown in the figure below The Guide details each of these stages and the technologies supporting them: Acquire: Through new NoSQL APIs, MySQL is able to ingest high volume, high velocity data, without sacrificing ACID guarantees, thereby ensuring data quality. Real-time analytics can also be run against newly acquired data, enabling immediate business insight, before data is loaded into Hadoop. In addition, sensitive data can be pre-processed, for example healthcare or financial services records can be anonymized, before transfer to Hadoop. Organize: Data is transferred from MySQL tables to Hadoop using Apache Sqoop. With the MySQL Binlog (Binary Log) API, users can also invoke real-time change data capture processes to stream updates to HDFS. Analyze: Multi-structured data ingested from multiple sources is consolidated and processed within the Hadoop platform. Decide: The results of the analysis are loaded back to MySQL via Apache Sqoop where they inform real-time operational processes or provide source data for BI analytics tools. So how are companies taking advantage of this today? As an example, on-line retailers can use big data from their web properties to better understand site visitors’ activities, such as paths through the site, pages viewed, and comments posted. This knowledge can be combined with user profiles and purchasing history to gain a better understanding of customers, and the delivery of highly targeted offers. Of course, it is not just in the web that big data can make a difference. Every business activity can benefit, with other common use cases including: - Sentiment analysis; - Marketing campaign analysis; - Customer churn modeling; - Fraud detection; - Research and Development; - Risk Modeling; - And more. As the guide discusses, Big Data is promising a significant transformation of the way organizations leverage data to run their businesses. MySQL can be seamlessly integrated within a Big Data lifecycle, enabling the unification of multi-structured data into common data platforms, taking advantage of all new data sources and yielding more insight than was ever previously imaginable. Download the guide to MySQL and Hadoop integration to learn more. I'd also be interested in hearing about how you are integrating MySQL with Hadoop today, and your requirements for the future, so please use the comments on this blog to share your insights.

• Non-English Character Display in Oracle SQL Developer

  - by thatjeffsmith

  I get a variation on this question at least once a week, if not more frequently. I’m from Israel, and the language on the databases is Hebrew. When I use the old and deprecated SQL*Plus (windows rich client) I can see the hebrew clearly, when I use the latest SQL Developer, I get gibberish. This question appears on the forums about every week or so as well. So what’s the deal? Well, it starts with a basic misunderstanding of NLS Client parameters. These should accurately reflect the language and locality setup on your LOCAL machine. DO NOT COPY what’s set in the database. The these parameters work together with the database so that information can be transferred back and forth correctly. Having the wrong NLS parameters locally can be bad. [ORACLE DOCS]Setting the NLS_LANG parameter properly is essential to proper data conversion. The character set that is specified by the NLS_LANG parameter should reflect the setting for the client operating system. Setting NLS_LANG correctly enables proper conversion from the client operating system character encoding to the database character set. When these settings are the same, Oracle Database assumes that the data being sent or received is encoded in the same character set as the database character set, so character set validation or conversion may not be performed. This can lead to corrupt data if conversions are necessary. OK, so what are you supposed to do? Set the Font! 9 times out of 10, this preference fixes the problem with display issues. Make sure you set a Font that supports the characters you’re trying to display. It’s as simple as that. This preference defines the font used to display characters in the editors and the data grids. If you have it set to a font that doesn’t have Hebrew character support – you’re not going to see Hebrew in SQL Developer. A few years ago…wow, like 15 years ago, I learned that the Tohama Font is pretty Unicode-friendly. Bad Font Selection A Font that’s not non-English friendly Good Font Selection Exact same text, except rendered with the Tahoma font Summary Having problems seeing non-English text in SQL Developer? Check the font! And do not start messing with NLS parameters without talking to your DBA first.

• Textures do not render on ATI graphics cards?

  - by Mathias Lykkegaard Lorenzen

  I'm rendering textured quads to an orthographic view in XNA through hardware instancing. On Nvidia graphics cards, this all works, tested on 3 machines. On ATI cards, it doesn't work at all, tested on 2 machines. How come? Culling perhaps? My orthographic view is set up like this: Matrix projection = Matrix.CreateOrthographicOffCenter(0, graphicsDevice.Viewport.Width, -graphicsDevice.Viewport.Height, 0, 0, 1); And my elements are rendered with the Z-coordinate 0. Edit: I just figured out something weird. If I do not call this spritebatch code above doing my textured quad rendering code, then it won't work on Nvidia cards either. Could that be due to culling information or something like that? Batch.Instance.SpriteBatch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend, SamplerState.LinearClamp, DepthStencilState.Default, RasterizerState.CullNone); ... spriteBatch.End(); Edit 2: Here's the full code for my instancing call. public void DrawTextures() { Batch.Instance.SpriteBatch.Begin(SpriteSortMode.Texture, BlendState.AlphaBlend, SamplerState.LinearClamp, DepthStencilState.Default, RasterizerState.CullNone, textureEffect); while (texturesToDraw.Count > 0) { TextureJob texture = texturesToDraw.Dequeue(); spriteBatch.Draw(texture.Texture, texture.DestinationRectangle, texture.TintingColor); } spriteBatch.End(); #if !NOTEXTUREINSTANCING // no work to do if (positionInBufferTextured > 0) { device.BlendState = BlendState.Opaque; textureEffect.CurrentTechnique = textureEffect.Techniques["Technique1"]; textureEffect.Parameters["Texture"].SetValue(darkTexture); textureEffect.CurrentTechnique.Passes[0].Apply(); if ((textureInstanceBuffer == null) || (positionInBufferTextured > textureInstanceBuffer.VertexCount)) { if (textureInstanceBuffer != null) textureInstanceBuffer.Dispose(); textureInstanceBuffer = new DynamicVertexBuffer(device, texturedInstanceVertexDeclaration, positionInBufferTextured, BufferUsage.WriteOnly); } if (positionInBufferTextured > 0) { textureInstanceBuffer.SetData(texturedInstances, 0, positionInBufferTextured, SetDataOptions.Discard); } device.Indices = textureIndexBuffer; device.SetVertexBuffers(textureGeometryBuffer, new VertexBufferBinding(textureInstanceBuffer, 0, 1)); device.DrawInstancedPrimitives(PrimitiveType.TriangleStrip, 0, 0, textureGeometryBuffer.VertexCount, 0, 2, positionInBufferTextured); // now that we've drawn, it's ok to reset positionInBuffer back to zero, // and write over any vertices that may have been set previously. positionInBufferTextured = 0; } #endif }

• New security configuration flag in UCM PS3

  - by kyle.hatlestad

  While the recent Patch Set 3 (PS3) release was mostly focused on bug fixes and such, a new configuration flag was added for security. In 10gR3 and prior versions, UCM had a component called Collaboration Manager which allowed for project folders to be created and groups of users assigned as members to collaborate on documents. With this component came access control lists (ACL) for content and folders. Users could assign specific security rights on each and every document and folder within a project. And it was possible to enable these ACL's without having the Collaboration Manager component enabled. But it took some special instructions (see technote# 603148.1) and added some extraneous pieces still related to Collaboration Manager. When 11g came out, Collaboration Manager was no longer available. But the configuration settings to turn on ACLs were still there. Well, in PS3 they've been cleaned up a bit and a new configuration flag has been added to simply turn on the ACL fields and none of the other collaboration bits. To enable ACLs: UseEntitySecurity=true Along with this configuration flag to turn ACLs on, you also need to define which Security Groups will honor the ACL fields. If an ACL is applied to a content item with a Security Group outside this list, it will be ignored. SpecialAuthGroups=HumanResources,Legal,Marketing Save the settings and restart the instance. Upon restart, two new metadata fields will be created: xClbraUserList, xClbraAliasList. If you are using OracleTextSearch as the search indexer, be sure to run a Fast Rebuild on the collection. On the Check In, Search, and Update pages, values are added by simply typing in the value and getting a type-ahead list of possible values. Select the value, click Add and then set the level of access (Read, Write, Delete, or Admin). If all of the fields are blank, then it simply falls back to just Security Group and Account access. As for how they are stored in the metadata fields, each entry starts with it's identifier: ampersand (&) symbol for users, "at" (@) symbol for groups, and colon (:) for roles. Following that is the entity name. And at the end is the level of access in paranthesis. e.g. (RWDA). And each entry is separated by a comma. So if you were populating values through batch loader or an external source, the values would be defined this way. Detailed information on Access Control Lists can be found in the Oracle Fusion Middleware System Administrator's Guide for Oracle Content Server.

• permanently load module

  - by Radu

  I have a Compaq Presario CQ-61 320SQ, I am using Ubuntu 10.04 because after update to 10.10 my mouse and touchpad won't work, network won't work, sound won't work ... (I managed to fix most of them after almost a month of googling, but not all, my 2 Desktops have no problem with 10.10) so I decided to switch back to 10.04, where I have a problem: My broadband speed is very low beacause of the kernel module r8169, I downloaded the good module r8101 and every time the computer boots have a rc.local entry to fix this. Question: Can I load the modul permanently from a specific location. I heard about /etc/modules but there I need the module name, but I have to load it from a specific path (where is the default path for that) Thank you. So I studied the script: It creates the file r8101.ko in /lib/modules/uname -r/kernel/drivers/net so I think as long as nobody will delete that file, and I don't update the kernel, maybe adding r8108 to /etc/modules will work, and add r8169 to blacklist ... I will give it a try. EDIT2: So I added r8101 to /etc/modules and blacklist r8169 to /etc/modprobe.d/blacklist.conf It still uses the old module, lsmod prints: radu@adu:~$ lsmod | grep r8 r8101 67626 0 r8169 34108 0 mii 4381 1 r8169 EDIT: the module is loaded using this script that came with it: #!/bin/sh # invoke insmod with all arguments we got # and use a pathname, as insmod doesn't look in . by default TARGET_PATH=/lib/modules/`uname -r`/kernel/drivers/net echo echo "Check old driver and unload it." check=`lsmod | grep r8169` if [ "$check" != "" ]; then echo "rmmod r8169" /sbin/rmmod r8169 fi check=`lsmod | grep r8101` if [ "$check" != "" ]; then echo "rmmod r8101" /sbin/rmmod r8101 fi echo "Build the module and install" echo "-------------------------------" >> log.txt date 1>>log.txt make all 1>>log.txt || exit 1 module=`ls src/*.ko` module=${module#src/} module=${module%.ko} if [ "$module" == "" ]; then echo "No driver exists!!!" exit 1 elif [ "$module" != "r8169" ]; then if test -e $TARGET_PATH/r8169.ko ; then echo "Backup r8169.ko" if test -e $TARGET_PATH/r8169.bak ; then i=0 while test -e $TARGET_PATH/r8169.bak$i do i=$(($i+1)) done echo "rename r8169.ko to r8169.bak$i" mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak$i else echo "rename r8169.ko to r8169.bak" mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak fi fi fi echo "Depending module.

• Top 5 Sites and Activities in San Francisco to Experience During Oracle OpenWorld

  - by kgee

  While Oracle OpenWorld may provide solutions and information on topics like how to simplify your IT, the importance of cloud, and what types of storage may satisfy your enterprise needs, who is going to tell you more about San Francisco? Here are some suggested sites and activities to experience after OpenWorld that aren’t too far from the Moscone Center. It is recommended to take a cab for the sake of time, but the 6 square miles that make up San Francisco will make for a quick trek to any of the following destinations: The Golden Gate BridgeAn image often associated with San Francisco, this bridge is one of the most impressive in the world. Take a walk across it, or view it from nearby Crissy Field, it is a sight that floors even the most veteran of San Franciscans. The Ferry BuildingLocated at the end of Market Street in the Embarcadero, the Ferry Building once served as a hub of water transport and trade. The building has a bay front view and an array of food choices and restaurants. It is easily accessible via the Muni, BART, trolley or by cab. It is a must-see in San Francisco, and not too far from the Moscone Center. Ride the Trolley to the CastroFor only $2, you can get go back in history for a moment on the Trolley. Take the F-line from the Embarcadero and ride it all the way to the Castro district. During the ride, you will get an overview of the landscape and cultures that are prevalent in San Francisco, but be wary that some areas may beg for an open mind more than others. Golden Gate ParkWhen you tire of the concrete jungle, the lucky part of being in San Francisco is that you can escape to a natural refuge, this park being one of the favorites. This park is known for its hiking trails, cultural attractions, monuments, lakes and gardens. It is one good reason to bring your sneakers to San Francisco, and is also a great place to picnic. Please be wary that it is easy to get lost, and it is advisable to bring a map (just in case) if you go. Haight AshburyFor a complete change of scenery, Haight Ashbury is known as one of the places hippies used to live and the location of "The Summer of Love." It is now a more affluent neighborhood with boutique shops and the occasional drum circle. While it may be perceived as grungy in certain spots, it is one of the most photographed places in San Francisco and an integral part of San Franciscan history.

• &ldquo;Our Users are Doing Something Surprising&rdquo;&hellip; but what?

  - by antonio romero

  I’ve just started a discussion on the OWB Linkedin Group based on a blog post from Laura Klein’s “Users Know” blog, entitled “Your Users are Doing Something Surprising”… As a PM I found the post thought-provoking and a good reminder to learn from our customers: ...You may have written user stories and work flows... But you know who didn’t read your user stories? That’s right: your users. The result? Somewhere out there, a whole lot of your users are doing something totally unexpected with your product.... Your customers want to do something with your product so badly that they’re going out of their way to come up with clever ways to do it on their own. There are three excellent reasons for you to know what your customers are actually doing with your product: So you know if you are missing an opportunity to pivot your product or marketing So you know if you are missing an important feature So you don’t accidentally destroy a commonly used workaround or "unplanned feature" Truer words were rarely blogged. In fact just in the last few weeks I have had several "users" (some customers, and some internal to Oracle, in fact) turn up having built unexpected but powerful things around OWB, because it has such extensibility mechanisms built into it: OMB*Plus, the old Java APIs back before 10.2, and now the code template/knowledge module framework OWB shares with ODI. Some of our external users show astounding knowledge of how to make OWB really sing. (We hope to feature case studies from several of them over the course of the year on the OWB blog.) My question to all of you: can you identify things you have done or are doing with OWB or that you depend on in it that you think would come as a surprise to us? This could be either some development so advanced as to leave us all gob-smacked, or just some common (to you) thing that you use it for that you find enormously valuable but that you think is a bit off the theoretical "main line" use case of loading data warehouses. I invite the readers of this blog to come visit the OWB and ODI LinkedIn group and share their unusual applications of OWB or the very ordinary-looking features that you don’t want us to forget or would like us to extend. Your anecdotes will impress the crowd and will also help shape future data integration products from Oracle... Come on, surprise us. :)

• Desktop Fun: Google Themed Icon Packs

  - by Asian Angel

  Are you an avid user of Google’s online services, but the icons for your desktop and app launcher shortcuts leave something to be desired? Now you can make those shortcuts shine with style using our Google Themed Icon Packs collection. Note: To customize the icon setup on your Windows 7 & Vista systems see our article here. Using Windows XP? We have you covered here. Sneak Preview For this week’s sneak preview we set up a Google Chrome themed desktop using the Simply Google Icon Collection shown below. Note: Original full-size wallpaper can be found here. We used Chromium to create a set of app shortcuts for various Google services on our desktop. Anyone who has done the same knows that the original icons do not look very good, so these icon packs can make those shortcuts look spectacular. Once the new icons were arranged for our desktop app shortcuts, we then pinned them to our Taskbar. Those are definitely looking nice!
