• Oracle BI and XS Energy Drinks – Don’t Miss the Amway Presentation!

  - by Michelle Kimihira

  By Maria Forney Amway is a global leader in the direct sales industry with $10.9B in annual sales in more than 100 countries and territories. The company has implemented a global BI framework that provides accurate, consistent, and timely insights to support global, regional and local analytical research, business planning, performance measurement and assessment. Oracle BI EE is used by 1500 employees across Amway sales, marketing, finance, and supply chain business units as well as Amway affiliates in Europe, Russia, South Africa, Japan, Australia, Latin America, Malaysia, Vietnam, and Indonesia. Last week, I spoke with Lead Data Analyst with Amway Global Sales, Dan Arganbright, and IT Manager with Amway BI Competency Center, Mike Olson, about their upcoming presentation at Oracle OpenWorld in San Francisco. Scheduled during a prime speaking slot on Monday, October 1 at 12:15pm in Moscone West, 2007, Dan and Mike will discuss their experience building Amway’s Distributor Consulting solution, powered by Oracle BI EE. You can find more information here. As background, Amway offers people an opportunity to own their own businesses and consumers exclusive products in health and wellness, beauty and home care.  The Amway internal Sales organization is charged with consulting leadership-level Distributors to help them with data insights and ultimately grow their business. Until recently, this was a resource-intense process of gathering and formatting data. In some markets, it took over 40 hours to collect the data and produce the analysis needed for one consultation session. Amway began its global BI journey in 2006 and since then the company has migrated from having multiple technology providers and integration points to an integrated strategic vendor approach. Today, the company has standardized on Oracle technology for BI.  Amway has achieved cost savings through the retirement of redundant technology platforms. In addition, Mike’s organization has led the charge to align disparate BI organizations into a BI Competency Center.  The following diagram highlights the simplicity of the standardized architecture of Amway today. Dubbed Distributor Consulting, Amway has developed a BI solution using the Oracle technology stack to help Distributor leaders grow their businesses. The Distributor Consulting solution provides over 40 metrics for Sales staff to provide data-driven insights on the Distributors and organizations they support.  Using Oracle BI EE, Exadata, and Oracle Data Integrator, Amway provides customized and personalized business intelligence, and the Oracle BI EE dashboards were developed by the Amway Sales organization, which demonstrates business empowerment of the technology. Amway is also leveraging the power of BI to drive business growth in all of its markets.  A new set of Distributor Segmentation metrics are enabling a better understanding of distributor behaviors. A Global Scorecard that Amway developed provides key metrics at a market and global level for executive-level discussions. Product Analysis teams can now highlight repeat purchase rates, product penetration and the success of CRM campaigns. In the words of Dan and Mike, the addition of Exadata 11 months ago has been “a game changer.”  Amway has been able to dramatically reduce complexity, improve performance and increase business productivity and cost savings. For example, the number of indexes on the global data warehouse was reduced from more than 1,000 to less than 20.  Pulling data for the highest level distributors or the largest markets in the company now can be done in minutes instead of hours.  As a result, IT has shifted from performance tuning and keeping the system operational to higher-value business-focused activities. •       “The distributors that have been introduced to the BI reports have found them extremely helpful. Because they have never had this kind of information before, when they were presented with the reports, they wanted to take action immediately!”  -     Sales Development Manager in Latin America Without giving away more, the Amway case study presentation will be one of the unique customer sessions at OpenWorld this year.

• SharePoint 2010 release date - is it that important?

  - by CharlesLee

  There has been lots of excitement in the SharePoint community over the last few days as Microsoft have announced the official release date of SharePoint 2010. May 12th is the date for your diaries (RTM in April.) The twittersphere has been telling everyone for the last few days about this news and there is much excitement. The major conferences this year all seem to have a SharePoint 2010 focus and some are entirely focussed on the new product (e.g. SharePoint Evolution Conference.)  Now by all accounts Microsoft have plugged some significant functionality gaps that exist in WSS 3.0 and MOSS 2007 and provided some exciting new functionality.  You don't need me to tell you about these as the MVPs (and other community members) are doing a sterling job, after all that is why Microsoft has MVPs in the first place. Lets get real for a second though as there is a significant investment involved in moving to SharePoint 2010:  Firstly you need 64 bit architecture across the board, now for some environments that is no inconsequential hurdle, that's a pretty significant roadblock.   The development farm, test farm and UAT farm are all going to require the same infrastructure upgrades. To take advantage of the tooling for SP2010 you will need to upgrade to Visual Studio 2010 and your development team is going to require 64 bit hardware/OS too.  I would not recommend installing SP 2010 in client installation mode (i.e. for Windows 7) on your developer machines, I would use this for demo machines only. Something that lots of people seem to forget in all their whooping and hollering about the new release is that there is a large amount of end user training going to be required as the browser UI has now adopted the omnipotent ribbon interface and there are other new and more complicated features. SharePoint Designer has also entirely changed in both look and feel and some significant feature changes have taken place. Lest we should forget that some companies have not long upgraded to MOSS 2007 and are yet to see a significant ROI for that project. And the reticence that most companies feel about implementing v1 Microsoft products.  This is only the surface of the deeper issues which would be involved in any upgrade process, so I guess I share a small part of the concern voiced by Mark Miller of EndUserSharePoint.com.  Is SharePoint 2010 relevant? I don't share this sentiment in its entirety as I firmly believe that all companies should be looking at SharePoint 2010 from day one, however most large scale existing implementations of MOSS 2007 are going to be several years away from a serious upgrade project.  So should the conference organisers and the SharePoint community as a whole be a little more understanding of the real world issues?  It's easy to get carried away in the excitement of a new product and new tools to play with but there needs to be a focus on the real world issues that most people are facing day to day and at the moment and for the short term future (at the very least the next 12 months) that is fairly and squarely in the WSS 2.0/3.0 and SPS 2003/MOSS 2007 camps. Don't get me wrong, I am very very excited about getting to grips with SharePoint 2010 in the real world and I cannot wait for my first real project to come along, but for now I am just being realistic about the reality for most people who work with SharePoint. I have been spending a lot of time on www.sharepointoverflow.com recently as there is a community of people building up who are committed to answering the real world questions that folks are dealing with every day.  I urge you to take a look and either ask or answer some questions direct from the front line of the SharePoint world.

• Book Reviews: Art of Community and Eyetracking Web Usability

  - by ultan o'broin

  Holidays time offers a chance to catch up on some user experience and user assistance related material. So, two short book reviews (which I considered using my new Tumblr blog for. More about that another time) coming up. The Art of Community by Jono Bacon Excellent starting point for anyone wanting to get going in the community software (FLOSS, for example) space or understand how to set up, manage, and leverage the collective intelligence of communities for whatever ends. The book is a little too long in my opinion, and of course, usage of what Jono is recommending needs to be nuanced and adapted for enterprise applications space (hardly surprising there is a lot about Ubuntu, Lug Radio, and so on given Jono's interests). Shame there wasn't more information on international, non-English community considerations too. Still, some great ideas and insight into setting up and managing communities that I will leverage (watch out for the results on this blog, later in 2011). One section, on collaborative writing really jumped out. It reinforced the whole idea that to successful community initiatives are based on instigators knowing what makes the community tick in the first place. How about this for insight into user profiles for people who write community user assistance (OK then, "doc") and what tools they might use (in this case, we're talking about Jokosher): "Most people who write documentation for open source software projects would fall into the category of power user. They are technology enthusiasts who are not interested in the super-technical avenues of programming, but want to help out. Many of these people have good writing skills and a good knowledge of using the software, so the documentation fit is natural. With Jokosher we wanted to acknowledge this profile of user. As such, instead of focussing on complex text processing tools, we encouraged our documentation contributors to use a wiki." The book is available for free here, and well as being available from usual sources. Eyetracking Web Usability by Jakob Nielsen and Kara Prentice Another fine book by established experts. I have some field experience of eyetracking studies myself --in the user assistance for enterprise applications space--though Jakob and Kara concentrate on websites for their research here. I would caution how much about websites transfers easily to the applications space, especially enterprise applications, as claimed in the book too. However, Jakob and Kara do make the case very well that understanding design goals (for example, productivity improvement in the case of applications) and the context of the software use is critical. Executing a study using eyetracking technology requires that you know what you want to test, can set up realistic tasks for testing by representative testers, and then analyze the results. Be precise, as lots of data will be generated (I think the authors underplay the effort in analyzing data too). What I found disappointing was the lack of emphasis on eyetracking as only part of the usability solution. It's really for fine-tuning designs in my opinion, and should be used after other design reviews. I also wasn't that crazy about the level of disengagement between the qualitative and quantitative side of this kind of testing that the book indicated. I think it is useful to have testers verbalize their thoughts and for test engineers to prompt, intervene, or guide as necessary. More on cultural or international aspects to usability testing might have been included too (websites are available to everyone). To conclude, I enjoyed the book, took on board some key takeaways about methodologies and found the recommendations sensible and easy to follow (for example about Forms layouts). Applying enterprise applications requirements such as those relating to user profiles, design goals, and overall context of use in conjunction with what's in this book would be the way to go here. It also made me think of how interesting it would be to compare eyetracking findings between website and enterprise applications usage.

• Pie Charts Just Don't Work When Comparing Data - Number 10 of Top 10 Reasons to Never Ever Use a Pie

  - by Tony Wolfram

  When comparing data, which is what a pie chart is for, people have a hard time judging the angles and areas of the multiple pie slices in order to calculate how much bigger one slice is than the others. Pie Charts Don't Work A slice of pie is good for serving up a portion of desert. It's not good for making a judgement about how big the slice is, what percentage of 100 it is, or how it compares to other slices. People have trouble comparing angles and areas to each other. Controlled studies show that people will overestimate the percentage that a pie slice area represents. This is because we have trouble calculating the area based on the space between the two angles that define the slice. This picture shows how a pie chart is useless in determing the largest value when you have to compare pie slices.   You can't compare angles and slice areas to each other. Human perception and cognition is poor when viewing angles and areas and trying to make a mental comparison. Pie charts overload the working memory, forcing the person to make complicated calculations, and at the same time make a decision based on those comparisons. What's the point of showing a pie chart when you want to compare data, except to say, "well, the slices are almost the same, but I'm not really sure which one is bigger, or by how much, or what order they are from largest to smallest. But the colors sure are pretty. Plus, I like round things. Oh,was I suppose to make some important business decision? Sorry." Bad Choices and Bad Decisions Interaction Designers, Graphic Artists, Report Builders, Software Developers, and Executives have all made the decision to use pie charts in their reports, software applications, and dashboards. It was a bad decision. It was a poor choice. There are always better options and choices, yet the designer still made the decision to use a pie chart. I'll expore why people make such poor choices in my upcoming blog entires. (Hint: It has more to do with emotions than with analytical thinking.) I've outlined my opinions and arguments about the evils of using pie charts in "Countdown of Top 10 Reasons to Never Ever Use a Pie Chart." Each of my next 10 blog entries will support these arguments with illustrations, examples, and references to studies. But my goal is not to continuously and endlessly rage against the evils of using pie charts. This blog is not about pie charts. This blog is about understanding why designers choose to use a pie chart. Why, when give better alternatives, and acknowledging the shortcomings of pie charts, do designers over and over again still freely choose to place a pie chart in a report? As an extra treat and parting shot, check out the nice pie chart that Wikipedia uses to illustrate the United States population by state.   Remember, somebody chose to use this pie chart, with all its glorious colors, and post it on Wikipedia for all the world to see. My next blog will give you a better alternative for displaying comparable data - the sorted bar chart.

• SQL SERVER – SQL Server Misconceptions and Resolution – A Practical Perspective – TechEd 2012 India

  - by pinaldave

  TechEd India 2012 is just around the corner and I will be presenting there in two different sessions. On the very first day of this event, my presentation will be all about SQL Server Misconceptions and Resolution – A Practical Perspective. The dictionary tells us that a “misconception” means a view or opinion that is incorrect and is based on faulty thinking or understanding. In SQL Server, there are so many misconceptions. In fact, when I hear some of these misconceptions, I feel like fainting at that very moment! Seriously, at one time, I came across the scenario where instead of using INSERT INTO…SELECT, the developer used CURSOR believing that cursor is faster (duh!). Here is the link the blog post related to this. Pinal and Vinod in 2009 I have been presenting in TechEd India for last three years. This is my fourth opportunity to present a technical session on SQL Server. Just like the previous years, I decided to present something different. Here is a novelty of this year: I will be presenting this session with Vinod Kumar. Vinod Kumar and I have a great synergy when we work together. So far, we have written one SQL Server Interview Questions and Answers book and 2 video courses: (1) SQL Server Questions and Answers (2) SQL Server Performance: Indexing Basics. Pinal and Vinod in 2011 When we sat together and started building an outline for this course, we had many options in mind for this tango session. However, we have decided that we will make this session as lively as possible while keeping it natural at the same time. We know our flow and we know our conversation highlight, but we do not know what exactly each of us is going to present. We have decided to challenge each other on stage and push each other’s knowledge to the verge. We promise that the session will be entertaining with lots of SQL Server trivia, tips and tricks. Here are the challenges that I’ll take on: I will puzzle Vinod with my difficult questions I will present such misconception that Vinod will have no resolution for it. I need your help.  Will you help me stump Vinod? If yes, come and attend our session and join me to prove that together we are superior (a friendly brain clash, but we must win!). SQL Server enthusiasts and SQL Server fans are going to have gala time at #TechEdIn as we have a very solid lineup of the speaker and extremely interesting sessions at TechEdIn. Read the complete blog post of Vinod. Session Details Title: SQL Server Misconceptions and Resolution – A Practical Perspective (Add to Calendar) Abstract: “Earth is flat”! – An ancient common misconception, which has been proven incorrect as we progressed in modern times. In this session we will see various database misconceptions prevailing and their resolution with the aid of the demos. In this unique session audience will be part of the conversation and resolution. Date and Time: March 21, 2012, 15:15 to 16:15 Location: Hotel Lalit Ashok - Kumara Krupa High Grounds, Bengaluru – 560001, Karnataka, India. Add to Calendar Please submit your questions in the comments area and I will be for sure discussing them during my session. If I pick your question to discuss during my session, here is your gift I commit right now – SQL Server Interview Questions and Answers Book.

• Tough Decisions

  - by Johnm

  There was once a thriving business that employed two Database Administrators, Sam and Jim. Both DBAs were certified, educated and highly talented in their skill sets. During lunch breaks these two DBAs were often found together discussing best practices, troubleshooting techniques and the latest release notes for the upcoming version of SQL Server. They genuinely loved what they did. The maintenance of the first database was the responsibility of Sam. He was the architect of this server's setup and he was very meticulous in its configuration. He regularly monitored the health of the database, validated backup files and regularly adhered to the best practices that were advocated by well respected professionals. He was very proud of the fact that there was never a database that he managed that lost data or performed poorly. The maintenance of the second database was the responsibility of Jim. He too was the architect of this server's setup. At the time that he built this server, his understanding of the finer details of configuration were not as clear as they are today. The server was build on a shoestring budget and with very little time for testing and implementation. Jim often monitored the health of the database; but in more of a reactionary mode due to user complaints of slowness or failed transactions. Deadlocks abounded and the backup files were never validated. One day, the announcement was made that revealed that the business had hit financially hard times. Budgets were being cut, limitation on spending was implemented and the reduction in full-time staff was required. Since having two DBAs was regarded a luxury by many, this meant that either Sam or Jim were about to find themselves out of a job. Sam and Jim's boss, Frank, was faced with a very tough decision. Sam's performance was flawless. His techniques and practices were perfection. The databases he managed were reliable and efficient. His solutions are "by the book". When given a task it is certain that, while it may take a little longer, it will be done right the first time. Jim's techniques and practices were not perfect; but effective and responsive. He made mistakes regularly; but he shows that he learns from them and they often result in innovative solutions. When given a task it is certain that, while the results may require some tweaking, it will be done on time and under budget. You are Frank's best friend. He approaches you and presents this scenario. He must layoff one of his valued DBAs the very next morning. Frank asks you: "All else being equal, who would you let go? and Why?" Another pertinent question is raised: "Regardless of good times or bad, if you had to choose, which DBA would you want on your team when tough challenges arise?" Your response is. (This is where you enter a comment below)

• Should I upgrade to "Ubuntu 14.04 'Trusty Tahr'" from "Ubuntu 12.04 LTS" and what care do I need to take if I upgrade?

  - by PHPLover

  I'm basically a Web Developer(PHP Developer) by profession. I mainly work on PHP, jQuery, AJAX, Smarty, HTML and CSS, Bootstrap front-end web development framework. I've also installed and using IDEs/editors like Sublime Text, NetBeans. I'm also using Git repository for my website development as a versioning tool. I'm using "Ubuntu 12.04 LTS" on my machine almost since last two years. My machine configuraion is as follows: Memory : 3.7 GiB Processor : Intel® Core™ i3 CPU M 370 @ 2.40GHz × 4 Graphics : Unknown OS type : 64-bit Disk : 64-bit The important softwares present on my machine and which I'm using daily for my work are as follows: PHP : PHP 5.3.10-1ubuntu3.13 with Suhosin-Patch (cli) (built: Jul 7 2014 18:54:55) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies Apache web server : /usr/sbin/apachectl: 87: ulimit: error setting limit (Operation not permitted) Server version: Apache/2.2.22 (Ubuntu) Server built: Jul 22 2014 14:35:25 Server's Module Magic Number: 20051115:30 Server loaded: APR 1.4.6, APR-Util 1.3.12 Compiled using: APR 1.4.6, APR-Util 1.3.12 Architecture: 64-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/etc/apache2" -D SUEXEC_BIN="/usr/lib/apache2/suexec" -D DEFAULT_PIDLOG="/var/run/apache2.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="/var/run/apache2/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="mime.types" -D SERVER_CONFIG_FILE="apache2.conf" MySQL : 5.5.38-0ubuntu0.12.04.1 Smarty : 2.6.18 **NetBeans :** NetBeans IDE 8.0 (Build 201403101706) Sublime Text 2 : Version 2.0.2, Build 2221 Yesterday suddenly a pop-up message appeared on my screen asking me to upgrade to "Ubuntu 14.04 'Trusty Tahr'". I'd also be very happy to upgrade my system to "Ubuntu 14.04 'Trusty Tahr'". Following are the issues about which I'm little bit scared about and I need you all talented people's expert advice/help/suggestions on it: Will upgrading to "Ubuntu 14.04 'Trusty Tahr'" affect the softwares I mentioned above? I mean will I need to re-install/un-install and install these softwares too? Do I really need to and is it really a worth to upgrade to "Ubuntu 14.04 'Trusty Tahr'" from "Ubuntu 12.04 LTS" now? If I upgrade to "Ubuntu 14.04 'Trusty Tahr'" what advantage I'll get from web developer's point of view? Will the upgrade be hassle free and will I be ablr to continue my on-going work without any difficulties? Is "Ubuntu 14.04 'Trusty Tahr'" a LTS version and if yes till when it's going to provide support? These are the five crucial queries I have. If you want any further explanation from me please feel free to ask me. Thanks for spending some of your vaulable time in reading and understanding my issue. Any kind of help/comment/suggestion/answer would be highly appreciated. Though if someone gives canonical, precise and up to the mark answer, it will be of great help to me as well as other web developers using Ubuntu around the world. Once again thank you so much you great people around the globe. Waiting for your precious replies.

• Oracle Forms Migration to ADF - Webinar vom ORACLE Partner PITSS

  - by Thomas Leopold

    Tuesday, February 22, 2011 5:00 PM - 6:00 PM CET Free Webinar Re-Engineering Legacy Oracle Forms Migration from Forms to ADF - A Case Study Join Oracle's Grant Ronald and PITSS to see a software architecture comparison of Oracle Forms and ADF and a live step-by-step presentation on how to achieve a successful migration.

• Auto-cancel reason not found (6, 13906)

  - by Rajesh Sharma

  There are many errors in the application which are never invoked because of appropriate application configuration done at the time of implementation by the solution architects. So typically, as an application end user you would never stumble upon such errors. But what if the application administrator inadvertently changes the configuration/setup in the development, test, QA, or production environment? This is the time when you as an end user are introduced to a brand-new error for which you may not have a clue or understanding to what it means and neither the access/privilege to rectify it.    In this post we'll focus on one such error '6, 13906 - Auto-cancel reason not found'.   You get this error if you have not defined a Bill (Segment) Cancel Reason (Admin Menu, B, Bill Cancel Reason) code with System Default value of Turn off auto-cancel.   Consider a scenario when you are about to final bill an 'Account' for which the bill period's cut-off date you selected is falling on or after the Service Agreement's (SA) end/stop date (basically SA is Stopped with a date earlier than it was billed previously). And for the same 'Account' either: Bill segments exists that end after the SA's end date OR Non-closing bill segments exists that end on the SA's end date (OR closing bill segments that do not end on SA's end date or do not exist at all - remember closing/final bill segment is generated if the SA is in Stopped status).   CC&B detects such scenario and attempts to cancel all such violating bill segments automatically, but NOT if you are generating the bill Online. If online, the system assumes that you know what you are doing, and prompts you with error 2, 13716 - Bill segments that violate the SA (%1) End Date (%2) exist to take necessary action.   If in batch, system automatically cancels these kinds of bill segment(s).   Since this happens in the background, you have to define within the application which System Default Bill (Segment) cancellation reason code identified as Turn off auto-cancel, should be used by the process when it attempts to cancel any such violating bill segments (You already know that you cannot cancel a bill segment without giving a reason for cancellation).   So what exactly happens during batch billing?   Bill Segment generation routine at first determines billing eligibility of the service agreement being billed. One of the billing eligibility criteria is to check the SA's previous bill segments which have end dates greater than the current cut-off date/end date. Technically, the routine retrieves a count of such violating bill segments.     SELECT COUNT (*) FROM CI_BSEG WHERE SA_ID = :SA-ID AND BSEG_STAT_FLG = '50' -- Frozen AND END_DT IS NOT NULL AND (END_DT > '03-JUN-2010' -- Bill segment greater than SA's End Date OR OR (END_DT = '03-JUN-2010' AND CLOSING_BSEG_SW = 'N')) -- Non-closing bill segment ending on SA's end date   If the count is greater than zero, Bill segment generation routine executes another program to auto-cancel such bill segments. Auto-cancel program retrieves the 'Bill Cancel Reason' code which is identified as Turn off auto-cancel. Retrieved cancel reason code is then placed on the bill segments that are being cancelled automatically.   During this process if the routine fails to determine the bill cancel reason code having System Default Turn off auto-cancel because it was not been configured, you get a bill exception 6, 13906 - Auto-cancel reason not found.   Also note that duplicate or multiple System Default codes identified as Turn off auto-cancel are not allowed. CC&B would complain with an error 2, 54201.   Duplicate validation/check is also performed within Auto-cancel routine, if suppose for test purposes you executed a DML statement updating CI_BILL_CAN_RSN.BSCAN_SYS_DFLT_FLG with a value 'T'.

• Launch Webcast Q&A: Oracle WebCenter Suite 11g - The Platform for the Modern User Experience

  - by howard.beader(at)oracle.com

  Did you have a chance to watch the Oracle WebCenter Suite 11g Launch Webcast yet? Andy MacMillan presented some great information on the webcast and answered quite a few of your questions in the Q&A session as well. For your reading pleasure we have captured a number of the questions and answers and they are summarized below: Question: Can you tell me what should our Portal strategy be for integrating and extending our Oracle enterprise applications? Answer: We recommend that you look at this in two steps, the first would be to ensure that you have a good understanding of our common user experience architecture. Internally our product teams at Oracle are already investing in this quite heavily today for Fusion Applications and this is driving natural convergence from a UX strategy standpoint. The second step would be to look at how best to componentize the back office applications so that the business users across your organization can take advantage of these -- don't make it just about putting a new skin on top of what you already have from an application standpoint, instead look at how best to embed the social computing capabilities as part of the solution for your business users. Question: We are currently using the BEA WebLogic Portal now, should we stay on WLP or should we be looking at moving to WebCenter or when should we move to WebCenter? Answer: Our strategy has been called "Continue & Converge", this theme means that you can continue to use WebLogic or Plumtree portals until your organization is ready to move to WebCenter and in the mean time you can continue to deploy what you need to in your organization of WLP or WCI Portals with the full support of Oracle. In addition WebCenter Services can be leveraged for social computing to complement what you are already doing today and enable your organization to take advantage of some of the latest and greatest social computing capabilities. We have migration scripts and conversion capabilities available as well as programs where Oracle can help you evaluate your options to decide how best to move forward. WebCenter provides the best of the best capabilities and will enable you to take advantage of new capabilities that may not exist in your current portal today. In the end though it's up to you as a customer as to when you want to make the transition to Oracle WebCenter Suite. Question: Can you tell me how is Oracle leveraging WebCenter internally and for its Application and Middleware product UX strategies? Answer: Internally, Oracle is leveraging WebCenter for our employees and thus far we are seeing significant updates with our users taking advantage of the business activity streams, team spaces and collaboration capabilities. From a product strategy standpoint, our product teams are taking advantage of the common user experience architecture and leveraging WebCenter to provide social and collaborative capabilities to the Oracle Applications and providing new types of composite applications with what is coming with Fusion Applications. WebCenter also provides a common user experience across all the products in the Oracle Fusion Middleware family as well. Question: Our organization is currently using SharePoint, but we are also an Oracle Applications customer, how should we be thinking about WebCenter as we move forward? Answer: Great question. Typically, we are seeing organizations using SharePoint for its core use cases of small team collaboration and file server replacement. WebCenter can connect to SharePoint as a content source to feed into WebCenter quite easily and it leverages the robust Oracle ECM product under WebCenter as well. In addition, SharePoint team sites can be connected to WebCenter utilizing our SharePoint connector. With Oracle WebCenter though, we are really targeting business users and enterprise applications, thus affecting positive change on the processes that drive the business to improve productivity across your organization. Question: Are organizations today using WebCenter as a Web platform for externally facing public websites? Answer: Yes, we are seeing a convergence around web content management and portal types of websites with customers converting them from just broadcasting content to making it a much richer personalized experience and also exposing back-office applications as well. Web Content Management capabilities are already embedded in WebCenter so that organizations can take advantage now of the benefits a personalized web experience provides for your customers. This is simply a short summary of a few of the questions addressed on the webcast, please tune in now to learn more about Oracle WebCenter, the user experience platform for the enterprise and the web!

• Boost Netbook Speed with an SD Card & ReadyBoost

  - by Matthew Guay

  Looking for a way to increase the performance of your netbook?  Here’s how you can use a standard SD memory card or a USB flash drive to boost performance with ReadyBoost. Most netbooks ship with 1Gb of Ram, and many older netbooks shipped with even less.  Even if you want to add more ram, often they can only be upgraded to a max of 2GB.  With ReadyBoost in Windows 7, it’s easy to boost your system’s performance with flash memory.  If your netbook has an SD card slot, you can insert a memory card into it and just leave it there to always boost your netbook’s memory; otherwise, you can use a standard USB flash drive the same way. Also, you can use ReadyBoost on any desktop or laptop; ones with limited memory will see the most performance increase from using it. Please Note:  ReadyBoost requires at least 256Mb of free space on your flash drive, and also requires minimum read/write speeds.  Most modern memory cards or flash drives meet these requirements, but be aware that an old card may not work with it. Using ReadyBoost Insert an SD card into your card reader, or connect a USB flash drive to a USB port on your computer.  Windows will automatically see if your flash memory is ReadyBoost capable, and if so, you can directly choose to speed up your computer with ReadyBoost. The ReadyBoost settings dialog will open when you select this.  Choose “Use this device” and choose how much space you want ReadyBoost to use. Click Ok, and Windows will setup ReadyBoost and start using it to speed up your computer.  It will automatically use ReadyBoost whenever the card is connected to the computer. When you view your SD card or flash drive in Explorer, you will notice a ReadyBoost file the size you chose before.  This will be deleted when you eject your card or flash drive. If you need to remove your drive to use elsewhere, simply eject as normal. Windows will inform you that the drive is currently being used.  Make sure you have closed any programs or files you had open from the drive, and then press Continue to stop ReadyBoost and eject your drive. If you remove the drive without ejecting it, the ReadyBoost file may still remain on the drive.  You can delete this to save space on the drive, and the cache will be recreated when you use ReadyBoost next time. Conclusion Although ReadyBoost may not make your netbook feel like a Core i7 laptop with 6GB of RAM, it will still help performance and make multitasking even easier.  Also, if you have, say, a memory stick and a flash drive, you can use both of them with ReadyBoost for the maximum benefit.  We have even noticed better battery life when multitasking with ReadyBoost, as it lets you use your hard drive less.  SD cards and thumb drives are relatively cheap today, and many of us have several already, so this is a great way to improve netbook performance cheaply.

• Introducing functional programming constructs in non-functional programming languages

  - by Giorgio

  This question has been going through my mind quite a lot lately and since I haven't found a convincing answer to it I would like to know if other users of this site have thought about it as well. In the recent years, even though OOP is still the most popular programming paradigm, functional programming is getting a lot of attention. I have only used OOP languages for my work (C++ and Java) but I am trying to learn some FP in my free time because I find it very interesting. So, I started learning Haskell three years ago and Scala last summer. I plan to learn some SML and Caml as well, and to brush up my (little) knowledge of Scheme. Well, a lot of plans (too ambitious?) but I hope I will find the time to learn at least the basics of FP during the next few years. What is important for me is how functional programming works and how / whether I can use it for some real projects. I have already developed small tools in Haskell. In spite of my strong interest for FP, I find it difficult to understand why functional programming constructs are being added to languages like C#, Java, C++, and so on. As a developer interested in FP, I find it more natural to use, say, Scala or Haskell, instead of waiting for the next FP feature to be added to my favourite non-FP language. In other words, why would I want to have only some FP in my originally non-FP language instead of looking for a language that has a better support for FP? For example, why should I be interested to have lambdas in Java if I can switch to Scala where I have much more FP concepts and access all the Java libraries anyway? Similarly: why do some FP in C# instead of using F# (to my knowledge, C# and F# can work together)? Java was designed to be OO. Fine. I can do OOP in Java (and I would like to keep using Java in that way). Scala was designed to support OOP + FP. Fine: I can use a mix of OOP and FP in Scala. Haskell was designed for FP: I can do FP in Haskell. If I need to tune the performance of a particular module, I can interface Haskell with some external routines in C. But why would I want to do OOP with just some basic FP in Java? So, my main point is: why are non-functional programming languages being extended with some functional concept? Shouldn't it be more comfortable (interesting, exciting, productive) to program in a language that has been designed from the very beginning to be functional or multi-paradigm? Don't different programming paradigms integrate better in a language that was designed for it than in a language in which one paradigm was only added later? The first explanation I could think of is that, since FP is a new concept (it isn't new at all, but it is new for many developers), it needs to be introduced gradually. However, I remember my switch from imperative to OOP: when I started to program in C++ (coming from Pascal and C) I really had to rethink the way in which I was coding, and to do it pretty fast. It was not gradual. So, this does not seem to be a good explanation to me. Or can it be that many non-FP programmers are not really interested in understanding and using functional programming, but they find it practically convenient to adopt certain FP-idioms in their non-FP language? IMPORTANT NOTE Just in case (because I have seen several language wars on this site): I mentioned the languages I know better, this question is in no way meant to start comparisons between different programming languages to decide which is better / worse. Also, I am not interested in a comparison of OOP versus FP (pros and cons). The point I am interested in is to understand why FP is being introduced one bit at a time into existing languages that were not designed for it even though there exist languages that were / are specifically designed to support FP.

• SQL SERVER – How to Ignore Columnstore Index Usage in Query

  - by pinaldave

  Earlier I wrote about SQL SERVER – Fundamentals of Columnstore Index and very first question I received in email was as following. “We are using SQL Server 2012 CTP3 and so far so good. In our data warehouse solution we have created 1 non-clustered columnstore index on our large fact table. We have very unique situation but your article did not cover it. We are running few queries on our fact table which is working very efficiently but there is one query which earlier was running very fine but after creating this non-clustered columnstore index this query is running very slow. We dropped the columnstore index and suddenly this one query is running fast but other queries which were benefited by this columnstore index it is running slow. Any workaround in this situation?” In summary the question in simple words “How can we ignore using columnstore index in selective queries?” Very interesting question – you can use I can understand there may be the cases when columnstore index is not ideal and needs to be ignored the same. You can use the query hint IGNORE_NONCLUSTERED_COLUMNSTORE_INDEX to ignore the columnstore index. SQL Server Engine will use any other index which is best after ignoring the columnstore index. Here is the quick script to prove the same. We will first create sample database and then create columnstore index on the same. Once columnstore index is created we will write simple query. This query will use columnstore index. We will then show the usage of the query hint. USE AdventureWorks GO -- Create New Table CREATE TABLE [dbo].[MySalesOrderDetail]( [SalesOrderID] [int] NOT NULL, [SalesOrderDetailID] [int] NOT NULL, [CarrierTrackingNumber] [nvarchar](25) NULL, [OrderQty] [smallint] NOT NULL, [ProductID] [int] NOT NULL, [SpecialOfferID] [int] NOT NULL, [UnitPrice] [money] NOT NULL, [UnitPriceDiscount] [money] NOT NULL, [LineTotal] [numeric](38, 6) NOT NULL, [rowguid] [uniqueidentifier] NOT NULL, [ModifiedDate] [datetime] NOT NULL ) ON [PRIMARY] GO -- Create clustered index CREATE CLUSTERED INDEX [CL_MySalesOrderDetail] ON [dbo].[MySalesOrderDetail] ( [SalesOrderDetailID]) GO -- Create Sample Data Table -- WARNING: This Query may run upto 2-10 minutes based on your systems resources INSERT INTO [dbo].[MySalesOrderDetail] SELECT S1.* FROM Sales.SalesOrderDetail S1 GO 100 -- Create ColumnStore Index CREATE NONCLUSTERED COLUMNSTORE INDEX [IX_MySalesOrderDetail_ColumnStore] ON [MySalesOrderDetail] (UnitPrice, OrderQty, ProductID) GO Now we have created columnstore index so if we run following query it will use for sure the same index. -- Select Table with regular Index SELECT ProductID, SUM(UnitPrice) SumUnitPrice, AVG(UnitPrice) AvgUnitPrice, SUM(OrderQty) SumOrderQty, AVG(OrderQty) AvgOrderQty FROM [dbo].[MySalesOrderDetail] GROUP BY ProductID ORDER BY ProductID GO We can specify Query Hint IGNORE_NONCLUSTERED_COLUMNSTORE_INDEX as described in following query and it will not use columnstore index. -- Select Table with regular Index SELECT ProductID, SUM(UnitPrice) SumUnitPrice, AVG(UnitPrice) AvgUnitPrice, SUM(OrderQty) SumOrderQty, AVG(OrderQty) AvgOrderQty FROM [dbo].[MySalesOrderDetail] GROUP BY ProductID ORDER BY ProductID OPTION (IGNORE_NONCLUSTERED_COLUMNSTORE_INDEX) GO Let us clean up the database. -- Cleanup DROP INDEX [IX_MySalesOrderDetail_ColumnStore] ON [dbo].[MySalesOrderDetail] GO TRUNCATE TABLE dbo.MySalesOrderDetail GO DROP TABLE dbo.MySalesOrderDetail GO Again, make sure that you use hint sparingly and understanding the proper implication of the same. Make sure that you test it with and without hint and select the best option after review of your administrator. Here is the question for you – have you started to use SQL Server 2012 for your validation and development (not on production)? It will be interesting to know the answer.

• Using the StopWatch class to calculate the execution time of a block of code

  - by vik20000in

    Many of the times while doing the performance tuning of some, class, webpage, component, control etc. we first measure the current time taken in the execution of that code. This helps in understanding the location in code which is actually causing the performance issue and also help in measuring the amount of improvement by making the changes. This measurement is very important as it helps us understand the problem in code, Helps us to write better code next time (as we have already learnt what kind of improvement can be made with different code) . Normally developers create 2 objects of the DateTime class. The exact time is collected before and after the code where the performance needs to be measured.  Next the difference between the two objects is used to know about the time spent in the code that is measured. Below is an example of the sample code.             DateTime dt1, dt2;             dt1 = DateTime.Now;             for (int i = 0; i < 1000000; i++)             {                 string str = "string";             }             dt2 = DateTime.Now;             TimeSpan ts = dt2.Subtract(dt1);             Console.WriteLine("Time Spent : " + ts.TotalMilliseconds.ToString());   The above code works great. But the dot net framework also provides for another way to capture the time spent on the code without doing much effort (creating 2 datetime object, timespan object etc..). We can use the inbuilt StopWatch class to get the exact time spent. Below is an example of the same work with the help of the StopWatch class.             Stopwatch sw = Stopwatch.StartNew();             for (int i = 0; i < 1000000; i++)             {                 string str = "string";             }             sw.Stop();             Console.WriteLine("Time Spent : " +sw.Elapsed.TotalMilliseconds.ToString());   [Note the StopWatch class resides in the System.Diagnostics namespace] If you use the StopWatch class the time taken for measuring the performance is much better, with very little effort.

• Know Your Audience, And/Or Your Customer

  - by steve.diamond

  Yesterday I gave an internal presentation to about 20 Oracle employees on "messaging," not messaging technology, but embarking on the process of building messages. One of the elements I covered was the importance of really knowing and understanding your audience. As a humorous reference I included two side-by-side photos of Oakland A's fans and Oakland Raiders fans. The Oakland A's fans looked like happy-go-lucky drunk types. The Oakland Raiders fans looked like angry extras from a low budget horror flick. I then asked my presentation attendees what these two groups had in common. Here's what I heard. --They're human (at least I THINK they're human). --They're from Oakland. --They're sports fans. After that, it was anyone's guess. A few days earlier we were putting the finishing touches on a sales presentation for one of our product lines. We had included an upfront "lead in" addressing how the economy is improving, yet that doesn't mean sales executives will have any more resources to add to their teams, invest in technology, etc. This "lead in" included miscellaneous news article headlines and statistics validating the slowly improving economy. When we subjected this presentation to internal review two days ago, this upfront section in particular was scrutinized. "Is the economy really getting better? I (exclamation point) don't think it's really getting better. Haven't you seen the headlines coming out of Greece and Europe?" Then the question TO ME became, "Who will actually be in the audience that sees and hears this presentation? Will s/he be someone like me? Or will s/he be someone like the critic who didn't like our lead-in?" We took the safe route and removed that lead in. After all, why start a "pitch" with a component that is arguably subjective? What if many of our audience members are individuals at organizations still facing a strong headwind? For reasons I won't go into here, it was the right decision to make. The moral of the story: Make sure you really know your audience. Harness the wisdom of the information your organization's CRM systems collect to get that fully informed "customer view." Conduct formal research. Conduct INFORMAL research. Ask lots of questions. Study industries and scenarios that have nothing to do with yours to see "how they do it." Stop strangers in coffee shops and on the street...seriously. Last week I caught up with an old friend from high school who recently retired from a 25 year career with the USMC. He said, "I can learn something from every single person I come into contact with." What a great way of approaching the world. Then, think about and write down what YOU like and dislike as a customer. But also remember that when it comes to your company's products, you are most likely NOT the customer, so don't go overboard in superimposing your own world view. Approaching the study of customers this way adds rhyme, reason and CONTEXT to lengthy blog posts like this one. Know your audience.

Shoutouts: In with the links I've listed below, Sigurd Snørteland also sent a link to this app he's working on which is actually pretty cool to see: ZuneLight. The code is not yet available. He also has a no-code demo of a Silverlight Media Center Pieter Voloshyn, Luiz Thadeu, and Jhun Iti have a very nice Silverlight image editor up: Thumba From SilverlightCream.com: WP7 - Silverlight on mobile Sigurd Snørteland submitted some links for me that have been translated to English from his blog. I hope the pages come out good because he's got a lot of good stuff on there. This one has a link to a presentation he did, and 4 projects you can load up in the emulator that he's converted to the phone: weather, worldclock, coverflow, and solitaire ... pretty cool... thanks for the links Sigurd! Understanding Page Orientation in Silverlight for Windows Phone Jeff Prosise has a really nice post up on page orientation in WP7 ... what it means to your app, how to detect it, and example code for what to do then... also love a quote by Jeff: "Silverlight for Windows Phone is the hottest thing since color TV" Why you should check out Expression Blend Behaviors when using Silverlight DaveDev has a post up describing Behaviors and why we should use them, plus tons of external links to resources, blogs, videos... all good stuff... Fiddler inspector for WCF Silverlight Polling Duplex and WCF RIA Joe Zhou announces and provides a link to a new Fiddler inspector that understands the framing in Polling Duplex and also raw binary xml and binary SOAP. Windows Phone Controls v0.7 Chris Eargle reports the release of Version 0.7 of the Windows Phone Controls project on CodePlex ... this includes a Pivot Control and a Panorama Control... both very nicely done. Binding to Silverlight ComboBox and Using SelectedValue, SelectedValuePath and DisplayMemberPath John Papa responds to a user question and put up a nice post about binding to a ComboBox and then go from the selected item to some other property ... code included No More Boxes!

• To sample or not to sample...

  - by [email protected]

  Ideally, we would know the exact answer to every question. How many people support presidential candidate A vs. B? How many people suffer from H1N1 in a given state? Does this batch of manufactured widgets have any defective parts? Knowing exact answers is expensive in terms of time and money and, in most cases, is impractical if not impossible. Consider asking every person in a region for their candidate preference, testing every person with flu symptoms for H1N1 (assuming every person reported when they had flu symptoms), or destructively testing widgets to determine if they are "good" (leaving no product to sell). Knowing exact answers, fortunately, isn't necessary or even useful in many situations. Understanding the direction of a trend or statistically significant results may be sufficient to answer the underlying question: who is likely to win the election, have we likely reached a critical threshold for flu, or is this batch of widgets good enough to ship? Statistics help us to answer these questions with a certain degree of confidence. This focuses on how we collect data. In data mining, we focus on the use of data, that is data that has already been collected. In some cases, we may have all the data (all purchases made by all customers), in others the data may have been collected using sampling (voters, their demographics and candidate choice). Building data mining models on all of your data can be expensive in terms of time and hardware resources. Consider a company with 40 million customers. Do we need to mine all 40 million customers to get useful data mining models? The quality of models built on all data may be no better than models built on a relatively small sample. Determining how much is a reasonable amount of data involves experimentation. When starting the model building process on large datasets, it is often more efficient to begin with a small sample, perhaps 1000 - 10,000 cases (records) depending on the algorithm, source data, and hardware. This allows you to see quickly what issues might arise with choice of algorithm, algorithm settings, data quality, and need for further data preparation. Instead of waiting for a model on a large dataset to build only to find that the results don't meet expectations, once you are satisfied with the results on the initial sample, you can  take a larger sample to see if model quality improves, and to get a sense of how the algorithm scales to the particular dataset. If model accuracy or quality continues to improve, consider increasing the sample size. Sampling in data mining is also used to produce a held-aside or test dataset for assessing classification and regression model accuracy. Here, we reserve some of the build data (data that includes known target values) to be used for an honest estimate of model error using data the model has not seen before. This sampling transformation is often called a split because the build data is split into two randomly selected sets, often with 60% of the records being used for model building and 40% for testing. Sampling must be performed with care, as it can adversely affect model quality and usability. Even a truly random sample doesn't guarantee that all values are represented in a given attribute. This is particularly troublesome when the attribute with omitted values is the target. A predictive model that has not seen any examples for a particular target value can never predict that target value! For other attributes, values may consist of a single value (a constant attribute) or all unique values (an identifier attribute), each of which may be excluded during mining. Values from categorical predictor attributes that didn't appear in the training data are not used when testing or scoring datasets. In subsequent posts, we'll talk about three sampling techniques using Oracle Database: simple random sampling without replacement, stratified sampling, and simple random sampling with replacement.

• Lazy Evaluation &ndash; Why being lazy in F# blows my mind!

  - by MarkPearl

  First of all – shout out to Peter Adams – from the feedback I have gotten from him on the last few posts of F# that I have done – my mind has just been expanded. I did a blog post a few days ago about infinite sequences – I didn’t really understand what was going on with it, and I still don’t really get it – but I am getting closer. In Peter’s last comment he made mention of Lazy Evaluation. I am ashamed to say that up till then I had never heard about lazy evaluation – how can evaluation be lazy? I mean, I know about lazy loading and that makes sense… but surely something is either evaluated or not! Well… a bit of reading today and I have been enlightened to a point – if you do know of any good articles explaining lazy evaluation please send them to me. So what is lazy evaluation and why is it useful? Lazy evaluation is a process whereby the system only computes the values needed and “ignores” the computations not needed. I’m going out on a limb here, but with this explanation in hand, imagine the following C# code… public int CalculatedVal() { int Val1 = 0; int Val2 = 0; for (int Count = 0; Count < 1000000; Count++) { Val1++; } return Val2; }   Normally, even though Val1 is never needed, the system would loop 1000000 times and add 1 to the current value of Val1. Imagine if the system realized this and so just skipped this segment of code and instead did the following…. public int CalculatedVal() { int Val1 = 0; return Val2; }   A massive saving in computation and wasted effort. Now I am pretty sure it isn’t as simple as this but I think this is the basic idea. For a more detailed explanation of lazy evaluation in c#, Pedram Rezei has a wonderful post on lazy evaluation and makes some C# comparisons. I am not going to take any thunder from him by repeating everything he said since I think he did such a good job of explaining it himself. What I am interested in though is how in F# do you tell something to have lazy evalution, and how do you know if something will be eager or lazy by looking at it. I found this post was useful. From reading around F# by default uses eager evaluation unless explicitly told to use lazy evaluation. One exception to this is sequences, which are lazy by default. Now reading about lazy evaluation has helped me understand more about F# coding… From my understanding of F# because of its declarative nature, most of the actual code you are declaring properties and rules – very little code is actually saying do this right now - but when it comes to a “do this” code section, it then evaluates and optimizes code and applies the rules. So props to lazy evaluation and its optimizations…

• help: cannot make ubuntu 64-bit v12.04 install work

  - by honestann

  I decided it was time to update my ubuntu (single boot) computer from 64-bit v10.04 to 64-bit v12.04. Unfortunately, for some reason (or reasons) I just can't make it work. Note that I am attempting a fresh install of 64-bit v12.04 onto a new 3TB hard disk, not an upgrade of the 1TB hard disk that has contained my 64-bit v10.04 installation. To perform the attempted install of v12.04 I unplug the SATA cable from the 1TB drive and plug it into the 3TB drive (to avoid risking damage to my working v10.04 installation). I downloaded the ubuntu 64-bit v12.04 install DVD ISO file (~1.6 GB) from the ubuntu releases webpage and burned it onto a DVD. I have downloaded the DVD ISO file 3 times and burned 3 of these installation DVDs (twice with v10.04 and once with my winxp64 system), but none of them work. I run the "check disk" on the DVDs at the beginning of the installation process to assure the DVD is valid. I also tried to install on two older 250GB seagate drives in the same computer. During every attempt I plug the same SATA cable (sda) into only one disk drive (the 3TB or one of the 250GB drives) and leave the other disk drives unconnected (for simplicity). Installation takes about 30 minutes on the 250GB drives, and about 60 minutes on the 3TB drive - not sure why. When I install on the 250GB drives, the install process finishes, the computer reboots (after the install DVD is removed), but I get a grub error 15. It is my understanding that 64-bit ubuntu (and 64-bit linux in general) has no problem with 3TB disk drives. In the BIOS I have tried having EFI set to "enabled" and "auto" with no apparent difference (no success). I have tried partitioning the drive in a few ways to see if that makes a difference, but so far it has not mattered. Typically I manually create partitions something like this: 8GB swap 8GB /boot ext4 3TB / ext4 But I've also tried the following, just in case it matters: 100MB boot efi 8GB swap 8GB /boot ext4 3TB / ext4 Note: In the partition dialog I specify bootup on the same drive I am partitioning and installing ubuntu v12.04 onto. It is a VERY DANGEROUS FACT that the default for this always comes up with the wrong drive (some other drive, generally the external drive). Unless I'm stupid or misunderstanding something, this is very wrong and very dangerous default behavior. Note: If I connect the SATA cable to the 1TB drive that has been my ubuntu 64-bit v10.04 system drive for the past 2 years, it boots up and runs fine. I guess there must be a log file somewhere, and maybe it gives some hints as to what the problem is. I should be able to boot off the 1TB drive with the 3TB drive connected as a secondary (non-boot) drive and get the log file, assuming there is one and someone tells me the name (and where to find it if the name is very generic). After installation on the 3TB drive completes and the system reboots, the following prints out on a black screen: Loading Operating System ... Boot from CD/DVD : Boot from CD/DVD : error: unknown filesystem grub rescue Note: I have two DVD burners in the system, hence the duplicate line above. The same install and reboot on the 250GB drives generates "grub error 15". Sigh. Any ideas? ========== motherboard == gigabyte 990FXA-UD7 CPU == AMD FX-8150 8-core bulldozer @ 3.6 GHz RAM == 8GB of DDR3 in 2 sticks (matched pair) HDD == seagate 3TB SATA3 @ 7200 rpm (new install 64-bit v12.04) HDD == seagate 1TB SATA3 @ 7200 rpm (current install 64-bit v10.04) GPU == nvidia GTX-285 ??? == no overclocking or other funky business USB == external seagate 2TB HDD for making backups DVD == one bluray burner (SATA) DVD == one DVD burner (SATA) The current ubuntu 64-bit v10.04 system boots and runs fine on a seagate 1TB.

• Tips to Make Your Website Cell Phone Friendly

  - by Aditi

  Working on a new website design? or Redesigning your website? There is a lot more to consider now a days not just user experience, clean code, CSS etc. one of the important attribute one must not miss, which is making them mobile friendly! With the growing use of handhelds & unlimited data plans, people browse on their cellphones! and All come in different sizes! it is tough to make a website that would look great not just on a high resolution widescreen monitor/LCD, but also should look equally impressive on the low resolutions of cellphones. We are today going to discuss about such factors that can help you make a website Cellphone Friendly. Fluid Width Layouts As we start discussing about this, Most people speak of the Fluid Width Layouts as vital step in moving your website to be mobile friendly. Fluid width allows the width of your website stretch or shrink depending on the browser size. However, having a layout which flows with the width of the screen’s resolution is certainly convenient, more often than not the website was originally laid out for a desktop in mind. Compressing a fluid layout to 320 pixels can do some serious damage to layout, Thus some people strongly believe it is far better to have a mobile style sheet and lay out the content specifically for that screen and have more control on the display. The best thing to do is to detect the type of platform that is connected to your website and disabling or changing some tools and effects to make it look better if not perfect. Keep Your Web Pages Short length One must avoid long pages on their website, a lot of scroll makes it very non user friendly for people, especially on mobile devices this is a huge draw back because of the longer load time it takes to download the webpage. Everyone likes crisp & concise content such pages are easier to load & browse. This makes your website accessible across all platforms. Also try to keep shorter urls, if they have to type..save them from that much work especially if someone is using a cellphone with no QWERTY keyboard it can be tough. Usable Navigation & Search Unlike Desktops, your website’s Navigation won’t super work on a cellphone. Keep in mind the user experience for cellphone users as you design your Navigation. Try to keep your content centered as they do have difficulty in reading the webpage. I always look upto Google and their pages as available on mobile as a great example. Keeping a functional & very visible search bar helps mobile users navigate by searching. Understanding Clean Website Code : Evolved for Mobile Clean code is important when you consider the diversity out there for handheld devices. Some cell phones may only understand WAP. More capable phones may understand WAP2, which allows rendering websites with XHTML and CSS. Most mobiles won’t display tables, floats, frames, JavaScript, and dynamic menus. Most cellphone will not support cookies. Devices at the high end of the mobile market such as BlackBerry, Palm, or the upcoming iPhone are highly capable and support nearly as much as a standard computer..but masses still do not have such phones. You can use specific emulators to test your website on mobile devices. Make sure your color combinations provide good contrast between foreground and background colors, particularly for devices with fewer color options.

• SQL SERVER – master Database Log File Grew Too Big

  - by pinaldave

  Couple of the days ago, I received following email and I find this email very interesting and I feel like sharing with all of you. Note: Please read the whole email before providing your suggestions. “Hi Pinal, If you can share these details on your blog, it will help many. We understand the value of the master database and we take its regular back up (everyday midnight). Yesterday we noticed that our master database log file has grown very large. This is very first time that we have encountered such an issue. The master database is in simple recovery mode; so we assumed that it will never grow big; however, we now have a big log file. We ran the following command USE [master] GO DBCC SHRINKFILE (N'mastlog' , 0, TRUNCATEONLY) GO We know this command will break the chains of LSN but as per our understanding; it should not matter as we are in simple recovery model.     After running this, the log file becomes very small. Just to be cautious, we took full backup of the master database right away. We totally understand that this is not the normal practice; so if you are going to tell us the same, we are aware of it. However, here is the question for you? What operation in master database would have caused our log file to grow too large? Thanks, [name and company name removed as per request]“ Here was my response to them: “Hi [name removed], It is great that you are aware of all the right steps and method. Taking full backup when you are not sure is always a good practice. Regarding your question what could have caused your master database log to grow larger, let me try to guess what could have happened. Do you have any user table in the master database? If yes, this is not recommended and also NOT a good practice. If have user tables in master database and you are doing any long operation (may be lots of insert, update, delete or rebuilding them), then it can cause this situation. You have made me curious about your scenario; do revert back. Kind Regards, Pinal” Within few minutes I received reply: “That was it Pinal. We had one of the maintenance task log tables created in the master table, which had many long transactions during the night. We moved it to newly created database named ‘maintenance’, and we will keep you updated.” I was very glad to receive the email. I do not suggest that any user table should be created in the master database. It should be left alone from user objects. Now here is the question for you – can you think of any other reason for master log file growth?
