  • Play a Webpage Display Prank in Google Chrome

    - by Asian Angel
    Are you looking for a fun but innocent prank to play on someone who loves using Google Chrome? If so then you may want to have a closer look at the Upside Down extension for Chrome. Before Here is our example webpage before starting the prank…looking all “normal like”. Upside Down in Action As soon as the extension has been installed you are ready to go. If you had a webpage open before installing the extension you will only need to refresh the page. As soon as the page has been refreshed or a new one is opened everything is going to look messed up very quickly. With the default setting there are five different “looks” available. To cycle through the five “looks” use the “Windows Key + Semicolon” or “Command + Semicolon” to toggle through them. On the sixth toggle the webpage will revert to normal (toggling afterwards starts the whole process again). Here are the five “looks” available…         Options There are options available for the extension where you can focus on just a specific effect or a group of effects. You can also enable a “Grayscale Effect” and even set a delay timer (a definite “evil touch”)! Think of the fun and surprised looks that await… Conclusion If you have been looking for a fun and unexpected prank for your favorite Google Chrome fan then this just might be what you have been looking for. Get ready to sit back and watch the fun.

  • Networking works on Live CD but not after installation.

    - by user9054
    Hi Friends, I have got this issue with Ubuntu 10.10. I have been with ubuntu 8.04 and then decided to try out ubuntu 10.10 . I booted with a LiveCD and was able to configure the wireless network painlessly using the livecd, so happily I installed ubuntu 10.10. As soon as ubuntu came up it detected the wireless network and i was able to assign a static IP to eth1 (i dont use DHCP option on my ADSL router) and enter a wap key and use pppoeconf to configure the dialer. The net was on and i was able to surf the net. All hunky dory so far. However on the next boot the fun started . It did not detect the wireless network. I could not see the network manager icon in the systray. I used ifconfig and saw that the entry for eth1 was missing. I used ifup eth1 and it said that eth1 was already up. Then i installed wifi-radar. Wifi-Radar detected the wireless network. I configured wifi-radar for the detected wireless network , set the wap driver as wext and used the manual IP settings. However on clicking connect wifi-radar started looking for a DHCP IP. I cannot understand why wifi-radar is using DHCP when I have specified manual settings. Then I decided to use the wired network to surf the net looking for a solution. So I plugged in the network cable from my modem , configured eth0 , used pppoeconf and connected the net. Then I foolishly decided to reboot my PC. And wonders of wonders , the same problem appeared. I cannot see eth0 in my ifconfig anymore. I used pon and it said something about network error or something. Now my ifconfig shows only lo .Can anybody help me on this. PS : 1) I tried linux mint 10 and had the same issue . on rebooting wireless network was not getting detected. 2) I have made myself the administrator so that there is no issue of rights or anything.

  • So, what&rsquo;s your blog URL?

    - by johndoucette
    Asked by many of my colleagues often enough, I decided to take the plunge and begin blogging. After many attempts to start and long discussions about what I should write about, I decided to give my “buddies” a series of lessons and tidbits to help them understand what it takes to manage a software development project in the real world. Stories of success and failure to keep hope alive. I am formally trained as a developer (BS/CS) and have scattered my code throughout the matrix since 1985 (officially working for the man). As I moved from job-to-job over my career, I have had good managers, bad ones, and ones who were – well, just sitting in the corner office. It wasn't until I began the transition and commitment to the role of project management that I began to take real software development management seriously. A boss once told me “put down the code. Start managing the people and process.” That was a scary time in my career. I loved solving really cool problems with a blank sheet of paper. It was an adrenaline rush to get an opportunity to start from scratch and write an application solution people would actually use and help them in their work/business. I felt that moving into “management” would remove me from the thrill and ownership I felt as a developer. It was a hard step to take, and one which I believe is hard for any developer. Well, I am here to help you through this transition. For those of you wanting to read my stories or learn about the tools and techniques I use on a daily basis, you too might just learn something you would have never thought of as an architect/developer. I am currently a Sr. Consultant at Magenic with the Boston branch office and primarily work with clients in the New England area. I am typically engaged as the lead project manager on our engagements, but also perform Application Lifecycle Management (ALM) assessments for development organizations as well as augment the Technical Evangelists for Microsoft and perform many Team Foundation Server (TFS) demos, installs and “get started” engagements. I have spoken at the New England Code Camp, our most recent CodeMastery event in Boston, and have written several whitepapers.   I am looking forward to helping you “Put down the code.” John Doucette

    One piece in the set of products offered in SQL Server 2008 R2 that has generated a lot of buzz and interest during its CTP phase is StreamInsight, Microsoft’s platform for Complex Event Processing. Microsoft’s information platform vision provides enterprises with a “complete approach” to managing information assets, enabling all businesses to gain strategic value from information from the desktop to the datacenter to the cloud. And StreamInsight V1 is one essential piece in this spectrum. After more than a year of blood, sweat, tears, and insane amounts of coffee we are proud to release the first version of our Complex Event Processing Framework.   Those of you who have been following our Community Technology Previews (CTPs) throughout last year have already had the possibility to familiarize themselves with the product. Early feedback was not only incredibly positive, but also very constructive and strongly influenced the final feature set. Four notable increments over our last public CTP are: Count windows Non-occurrence detection (Anti-Join) Dynamic query composition at runtime Synchronize time across input streams Additionally, many smaller issues and bugs were addressed. A few APIs slightly changed with respect to the November CTP, but porting your application to RTM should not require a lot of effort.   Here are the (english) bits - choosing the evaluation license during setup lets you already play with this version. Before you install, make sure to uninstall any previous CTP version:   StreamInsight X86StreamInsight X64   Within a few days, we will update our product page and add download links and instructions there as well.   The StreamInsight documentation is provided through a help file as part of the installation as well as through Books Online on MSDN.

  • WPF Control Toolkits Comparison for LOB Apps

    In preparation for a new WPF project Ive been researching options for WPF Control toolkits.  While we want a lot of the benefits of WPF, the application is a fairly typical line of business application (LOB).  So were not focused on things like media and animations, but instead a simple, solid, intuitive, and modern user interface that allows for well architected separation of business logic and presentation layers. While WPF is mature, it hasnt lived the long life that Winforms has yet, so there is still a lot of room for third party and community control toolkits to fill the gaps between the controls that ship with the Framework.  There are two such gaps I was concerned about.  As this is an LOB app, we have needs for presenting lots of data and not surprisingly much of it is in grid format with the need for high performance, grouping, inline editing, aggregation, printing and exporting and things that weve been doing with LOB apps for a long time.  In addition we want a dashboard style for the UI in which the user can rearrange and shrink and grow tiles that house the content and functionality.  From a cost perspective, building these types of well performing controls from scratch doesnt make sense.  So I evaluated what you get from the .NET Framework along with a few different options for control toolkits.  I tried to be fairly thorough, but know that this isnt a detailed benchmarking comparison or intense evaluation.  Its just meant to be a feature set comparison to be used when thinking about building an LOB app in WPF.  I tried to list important feature differences and notes based on my experience with the trial versions and what I found in documentation and reference materials and samples.  Ive also listed the importance of the controls based on how I think they are needed in LOB apps.  There are several toolkits available, but given I dont have unlimited time, I picked just a few.  Maybe Ill add on more later.  The toolkits I compared are: Teleriks RadControls for WPF since I had heard some good things about Telerik Infragistics NetAdvantage WPF since both I and the customer have some experience with the vendors tools WPF Toolkit on codeplex since many of my colleagues have used it Blacklight codeplex project which had WPF support for the Tile View control  (with Release 4.3 WPF is not going to be supported in favor of focusing only on SilverLight controls, so I dropped that from the comparison) Click Here to Download the WPF Control Toolkits Comparison Hopefully this helps someone out there.  Feel free to post a comment on your experiences or if you think something I listed is incorrect or missing.  Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • PMI South Florida Job Fair 2010

    - by Sam Abraham
    The South Florida Chapter of the Project Management Institute is planning a Job Fair slated for September 2010. This year has seen a significant improvement in the job market with many surveyed companies indicating their intention to add temporary or permanent staff to their workforce in the near future.   The Job Fair Initiative fits well within the chapter's message and goal for this year: "Exercising Social Responsibility" - Our responsibility as PMI volunteers at all levels towards our members and surrounding community.   Our Free-to-members Annual Job Fair will play an important role in connecting Recruiters, Exhibitors and Job Seekers together thereby helping hiring companies gain access to a large talent pool at an affordable cost (Totally free in certain cases, details to be revealed once finalized) while giving job seekers centralized access to many reputable hiring companies in the South Florida area.   My involvement in the 2010 Job Fair started with a good conversation I had with Bernie Saenz, President and CEO of the South Florida PMI Chapter, in a networking event a few months ago. I had approached him with a few ideas in line with his goal to serve the community and our members given today's difficult economic climate. Bernie indicated that the Project Manager for the 2010 Job Fair had just been appointed and invited me to participate in this important initiative as a member of her team. I simply couldn't resist and gladly accepted the invitation.   I chose an initial role as Recruiter Relations Lead which entails developing documentation and timelines for our project plan with regards to Recruiter Engagement as well as reaching out to recruiting companies to meet target representation at the Job Fair.   Being heavily involved in the local Technical community has afforded me the privilege of coming in contact with many reputable Technology Recruiting companies. (As a matter of fact, I already have 2 interested very reputable IT recruiting firms willing to join us at the fair)   The excitement for me however will be finding and reaching out to recruiters in areas of Project Management and Leadership that I might not have been exposed to before including Finance, Healthcare and Marketing, to name a few.   Keep an eye in the upcoming few weeks for official announcements on the PMI South Florida Job Fair 2010.   Environment.Exit(0);   -Sam Abraham Site Director - West Palm Beach .Net User Group Recruiter Relations Lead - PMI South Florida Job Fair 2010 Project Lead - Mentoring Programs- PMI South Florida

  • How and when to ask for a pay raise?

    - by Nico
    When should one ask for a pay raise? Will I know when the time is right for a pay raise? or should I just think "I deserve a pay raise for X and Y." When would be a moment to ask for a pay grade? For instance, if you are in a company that outsources to others, could it be the right moment to ask when they move you to a different physical workplace? Maybe a few weeks/months after you started working as a consultant at the client? Should you ask for one after engaging new technologies or something you've never worked with before? In short, should you ask for a raise for a "business motive" (they move you, they assign you new responsibilities), a "professional motive" (you are required to learn new languages or technologies), or a "personal motive" (you are having twins, your mother died and you need to arrange the funeral), or are all of the above potentially valid motives? How should one ask for it? Asking for a pay raise can be difficult for some people, how you deal with this? Do you just walk up to your manager and tell him "I need more money", "I think I deserve a pay raise"? Do you suggest you might have other offers on the table? Couldn't this be counterproductive if you actually really want to stay in the company you are in (because you like the environment, made a few friends, and like all the features they give you besides your pay grade; say: free sodas, parties, after-offices that happen pretty often, a ps3 you can grab when you are tired or want to chill out, courses, english classes, football games, etc, etc. [these would be my reasons not to leave]). I mean, how would you ask for a pay raise, effectively, but without pretending to threaten to leave the company if you don't get it? Because you don't actually want to. How would you deal with their answer? If they tell you they don't think you deserve a raise, would you ask for their reasons, would you get furious and trash the room? If they give you their reasons why they think you don't deserve a pay raise yet, would you discuss this with them or just take their opinion as factual? What if they ask you how much more you think you deserve to be being paid? Should you have thought this before-hand, or expect them to set the new grade? If they do agree to a pay raise, should you expect extra work to be thrown your way, or should everything remain the same, except your pay grade?

  • Getting Started with Kinect for Windows.

    - by Vishal
    Hello folks,      Recently I got involved in a project for building a demo application for one of our customers with Kinect for Windows. Yes, something similar what Tom Cruise did in the movie Minority Report. Waving arms, moving stuff around, swipes, speech recognition, manipulating computer screens without even touching it. Pretty cool!!! The idea in the movie showed us how technology would be after 50 years from that day.   Minority Report Movie clip.           Well, that 50 years of time frame got squeezed and recently on Feb 1st 2012, Microsoft released the official Kinect for Windows SDK. That’s just 10 years from the movie release. Although, the product is in it early stages but with developer creativity and continuously improving hardware, those features shown in the movie are not very far away from becoming a reality. Soon after releasing the SDK, Microsoft again announced in March the release of its new Kinect for Windows SDK version 1.5 which is coming out in sometime May. More history about Kinect. Anyways, so for a newbie with Kinect, where would you start. Here is what I would suggest you can do. Watch the Kinect for Windows Quick start Series by Den Fernandez. Download the Kinect for Windows SDK and start playing around with the demos in it. It also comes with some basic Kinect documentation. Coding4Fun Kinect Projects | Lot many more videos and open sources projects information. Kinect for Windows Session at Techdays NL demo by Jesus Rodriguez. Book: Beginning Kinect Programming with the Microsoft Kinect SDK.  | I did go through few of the chapters in this book and based on that, it does talk deeply about core Kinect concepts but in very easy to understand way. I would definitely suggest this book for any Kinect developers. I liked the way it explained the Gestures recognition in Chapter 6. Buy your Kinect device from either Amazon or NewEgg. You will get it cheaper then buying it from Microsoft Store. Personally, I love Newegg.com as I never had any order related or shipping issues with them. I always hate developing UI application but well, you would need to get your hands dirty with WPF too in order to work with Kinect. So get started with WPF concepts too. I will keep adding stuff to the list once I come across them but so far the above list would definitely get you started building your first Kinect apps. Till then Happy Kinecting…!!!!! Thanks, Vishal Mody

  • Chargeback and showback...both a 'throw back'

    - by llaszews
    Been getting asked again by customers and partners about chargeback and showback in the cloud so thought I would blog on my response to this question. Charge Back background, information and industry analysis: Cloud computing is all about shared resources. These shared resources are computer servers (including memory and CPU), network devices, hard disk storage, database servers, application servers, cooling, floor space, electricity and more. These resources are shared by departments within a company, or by a number of companies, when resources are hosted in the public or hybrid cloud. Currently, hosting providers that run other companies on their cloud platforms do not have an accurate way to measure the shared computing resources used by a specific user let alone used by a specific customer. Additionally, companies running their own cloud data centers, for private or hybrid clouds, have no way of measure and charging back the departments in the company that are using these shared cloud resources. In both cases, the lack of determine shared resource costs and to charge them back to the company, department or user that is using this resources is limited a clear measure of business benefit and impacting company’s ability to measure the Return on Investment (ROI). An IT chargeback system is an accounting strategy that applies the costs of IT services, hardware or software to the business unit in which they are used. This system contrasts with traditional IT accounting models in which a centralized department bears all of the IT costs in an organization and those costs are treated simply as corporate overhead. Showback involves showing the IT costs to a department or customer but not actually charging them for their IT usage. Showback is a gradual method of introducing chargeback into an enterprise. Most companies implement a show back mechanism before a full chargeback system is put in place. Oracle chargeback product: Oracle Enterprise Manager provides tools for defining detailed Chargeback plans spanning different metrics collected for each type of resources as well as defining Cost Centers for grouping costs across multiple developers. Chargeback plans can use not only usage based costs, but also configuration based costs (e.g. version of the platform) or fixed costs (e.g. flat-rate management fee). Chargeback has rich out of the box reports. Trending reports show how charge and resource consumption varies over time, while Summary reports show the breakdown of charges or usage by different dimensions such as Cost Center or Target Type. These reports help consumers in understanding how their charges relate to their consumption and also assist the IT department with budgeting and planning activities. With BI Publisher, the reports can be made available in a variety of formats such as PDF, HTML, Word, Excel or PowerPoint.

  • Kicking off the ODI12c Blog Series

    - by Madhu Nair
    Normal 0 false false false EN-US ZH-TW X-NONE MicrosoftInternetExplorer4 It is always exciting to talk about a new release, especially one as significant as the newly released Oracle Data Integrator 12c (ODI12c). Why? Because it is packed with features that addresses many requirements for the user community. If you missed sneak previews at this year's Oracle Open World sessions, do not despair. Because over the coming weeks the ODI12c team of developers and consultants will be sharing their perspective on key features, experiences and best practices for ODI12c right here through a series of blogs. Before diving into feature details in subsequent blogs it helps to understand the overall themes that went into developing ODI12c. Let the Productivity Flow: Let us face it. Designing for developer user experience is always top of mind to any enterprise software. ODI12c addresses this through the introduction of declarative flow based mappings (the topic of our next ODI blog by the way!!). Reusability has been addressed though the introduction of reusable mappings cutting down development times for repeated logics. An enhanced debugger makes life easy for complex granular debugging scenarios. Unique repository IDs now allow you to manage multiple repositories. Performance is Paramount: Another major area of focus for ODI12c is performance. Increased parallelism (like the multiple target table load feature), reduced session overheads and ability to customize loads plans through physical views all empower the user to tune run times for extreme performances. mapping showing multiple target load physical representation allowing users to choose execution options Integrating it all: This release is not just about ODI12c as a standalone product. Closer integration with Oracle GoldenGate now brings Change Data Capture (CDC) capabilities into ODI12c. Oracle Warehouse Builder (OWB) jobs can now be executed and monitored from within ODI12c. And ODI12c is fast becoming the de facto standard for Oracle Applications that need data integration in their solutions. The best example being the latest release of the Oracle BI Applications technology. Even as we bring you in-depth write-ups about the features there are some great previews and resources that are already out there. Like this super entry by beta partner Rittman Mead Consulting and this ODI12c Key Features White Paper. You can download ODI12c here (this post helps). The best though is the upcoming Executive Webcast featuring customers and executives who have seen and conceived the product. Don’t miss it!

  • viable part-time career in IT/programming?

    - by Rider
    Hi, I'd like to ask for some career advice from you people. Is there a viable job/career that can be done in programming/IT for the long term? Right now, I am thinking about website (PHP?) developer path. My background: I have a degree in computer science and have been a programmer/system analyst for almost 10 years. Lately I took a big break from programming and studied for a B.arch. degree (yes architecture), only to discover that architecture offers zero (0) jobs where I'm from, for 3 years already (and no, I am not going to move and the grass in not greener in other places). I have never been particularly interested in programming, in fact I was bored by it. But I was always quite good at both programming and system analysis, and very valued by practically all my employers. On the other hand, I have never been valued or offered a good job in any other field (although I can do many things, like design, architecture, translations, documentation, teaching, etc etc.) I guess the human component has been always more important for me in programming jobs - I value all the good people I worked with, but not projects. However, I have about zero skills or desire to be a project manager. I also have close to zero skills for selling myself. I like it best when I can do "my thing", have my niche, have an ownership of some project. Right now my career perspective is to do part time programming and to part time teach yoga. I have already started the yoga teaching part. Do you think that part time programming is viable? And what niche works best for that? I have considered web development, QA, or software development in a company like I did before. However, my fear is that when you do programming part-time, you get the most boring coding work, only to see your colleagues move to more interesting projects and up their respective career ladders. I also fear that part-timers are not especially needed either. And, since I don't share much enthusiasm at programming, I'd rather not be around young programmers boiling with geeky enthusiasm about coding, but rather QA mindset with people from different backgrounds and life paths might work better for me. Thanks for any advice, --Rider

  • New Slides - and a discussion about Dictionary Statistics

    - by Mike Dietrich
    First of all we have just upoaded a new version of the Upgrade and Migration Workshop slides with some added information. So please feel free to download them from here.The slides have one new interesting information which lead to a discussion I've had in the past days with a very large customer regarding their upgrades - and internally on the mailing list targeting an EBS database upgrade from Oracle 10.2 to Oracle 11.2. Why are we creating dictionary statistics during upgrade? I'd believe this forced dictionary statistics creation got introduced with the desupport of the Rule Based Optimizer in Oracle 10g. The goal: as RBO is not supported anymore we have to make sure that the data dictionary has fresh and non-stale statistics. Actually that would have led in Oracle 9i to strange behaviour in some databases - so in Oracle 9i this was strongly disrecommended. The upgrade scripts got hardcoded to create these stats. But during tests we had the following findings: It's important to create dictionary statistics the night before the upgrade. Not two weeks before, not 60 minutes before your downtime begins. But very close to the upgrade. From Oracle 10g onwards you'd just say: $ execute DBMS_STATS.GATHER_DICTIONARY_STATS; This is important to make sure you have fresh dictionary statistics during upgrade for performance reasons. Tests have shown that running an upgrade without valid dictionary statistics might slow down the whole upgrade by factors of 2x-3x. And it would be also a great idea post upgrade to create again fresh dictionary statistics when you've did suppress the stats creation during the upgrade process. Suppress? Yes, you could set this underscore parameter in the init.ora: _optim_dict_stats_at_db_cr_upg=FALSE to suppress the forced dictionary statistics collection during an upgrade. We believe strongly that (a) people using the default statistics creation process which will create dictionary statistics by default and (b) create fresh stats before upgrade on the dictionary. Therefore we find it save once you have followed our advice to use the underscore during upgrade. And we've taken out that forced statistics collection during upgrade in the next release of the database. Please note: If you are using the DBUA for the upgrade it will remove underscore parameters for the upgrade run to improve performance - which is generally a good idea. So you'll have to start the DBUA with that call: $ dbua -initParam "_optim_dict_stats_at_cb_cr_upg"=FALSE -Mike

  • New TPerlRegEx Compatible with Delphi XE

    - by Jan Goyvaerts
    The new RegularExpressionsCore unit in Delphi XE is based on the PerlRegEx unit that I wrote many years ago. Since I donated full rights to a copy rather than full rights to the original, I can continue to make my version of TPerlRegEx available to people using older versions of Delphi. I did make a few changes to the code to modernize it a bit prior to donating a copy to Embarcadero. The latest TPerlRegEx includes those changes. This allows you to use the same regex-based code using the RegularExpressionsCore unit in Delphi XE, and the PerlRegEx unit in Delphi 2010 and earlier. If you’re writing new code using regular expressions in Delphi 2010 or earlier, I strongly recomment you use the new version of my PerlRegEx unit. If you later migrate your code to Delphi XE, all you have to do is replace PerlRegEx with RegularExrpessionsCore in the uses clause of your units. If you have code written using an older version of TPerlRegEx that you want to migrate to the latest TPerlRegEx, you’ll need to take a few changes into account. The original TPerlRegEx was developed when Borland’s goal was to have a component for everything on the component palette. So the old TPerlRegEx derives from TComponent, allowing you to put it on the component palette and drop it on a form. The new TPerlRegEx derives from TObject. It can only be instantiated at runtime. If you want to migrate from an older version of TPerlRegEx to the latest TPerlRegEx, start with removing any TPerlRegEx components you may have placed on forms or data modules and instantiate the objects at runtime instead. When instantiating at runtime, you no longer need to pass an owner component to the Create() constructor. Simply remove the parameter. Some of the property and method names in the original TPerlRegEx were a bit unwieldy. These have been renamed in the latest TPerlRegEx. Essentially, in all identifiers SubExpression was replaced with Group and MatchedExpression was replaced with Matched. Here is a complete list of the changed identifiers: Old Identifier New Identifier StoreSubExpression StoreGroups NamedSubExpression NamedGroup MatchedExpression MatchedText MatchedExpressionLength MatchedLength MatchedExpressionOffset MatchedOffset SubExpressionCount GroupCount SubExpressions Groups SubExpressionLengths GroupLengths SubExpressionOffsets GroupOffsets Download TPerlRegEx.

  • LCM says Smart List import is complete but actually its not...Here are probable reasons

    - by RahulS
    First of all some basics of smart list: Administrators use Smart Lists to create custom drop-down lists that users access from data form cells. When clicking in cells whose members are associated with a Smart List (as a member property), users select items from drop-down lists instead of entering data. Users cannot type in cells that contain Smart Lists. Smart Lists display in cells as down arrows that expand when users click into the cells. Below link will give you more information on Smart Lists: http://download.oracle.com/docs/cd/E17236_01/epm.1112/hp_admin/enum_pg.html I got a simple query today, "The LCM process generates and indicates a status of "Complete", however, the 3,018 records do not appear in the Planning application. No error exists in the log to identify the problem." Things which can be checked in this case: 1. Spaces are not allowed in the Entry Name, 2. Spaces are allowed in the Entry Label, 3. The name must start with an alpha character or underscore, 4. Valid characters for the remaining part of the name must be alpha, numeric, or an underscore, 5. Enter a name that is unique within the smart list, 6. I am not sure about the limits but I have seen 22,000 members loaded fine, 7. ID for every entry should be unique,  8. IDs need not to be consecutive, Ex: It was go from 1 to 100 then 500 to 900 then 1900 to 4500 etc. While import .xml file using LCM there were no errors in the foundation and LCM migration logs, but when checked in the HyS9PlanningSysErr.log, few errors were found:Ex: The name Data_Coord_(Prod)_ACS is invalid, The name Sr_Dir_b+Medcd_Gvt_Rel_Sls_Mkt is invalid, The name entered is invalid. Enter a name that is unique within the smart list, Also, we can Load Smart List dimensions and Smart List dimension entries using the /DS:HSP_SMARTLISTS parameter in outlineload utility: OutlineLoad /A:acpt /U:admin /M /I:c:/smartlist_create1.csv /DS:HSP_SMARTLISTS /L:c:/OutlineLogs/outlineLoad.log /X:c:/OutlineLogs/outlineLoad.exc SmartList Name, Operation, Label, Display Order, Missing Label, Use Form Missing Label, Entry ID, Entry Name, Entry Label SL1,addsmartlist,SL1Label,,,,,, SL1,addEntry,,,,,,entry1,entrylabel1 SL1,addEntry,,,,,,entry2,entrylabel2 Cheers..!!!

  • SQL SERVER – QUOTED_IDENTIFIER ON/OFF Explanation and Example – Question on Real World Usage

    - by Pinal Dave
    This is a follow up blog post of SQL SERVER – QUOTED_IDENTIFIER ON/OFF and ANSI_NULL ON/OFF Explanation. I wrote that blog six years ago and I had plans that I will write a follow up blog post of the same. Today, when I was going over my to-do list and I was surprised that I had an item there which was six years old and I never got to do that. In the earlier blog post I wrote about exploitation of the Quoted Identifier and ANSI Null. In this blog post we will see a quick example of Quoted Identifier. However, before we continue this blog post, let us see a refresh what both of Quoted Identifider do. QUOTED IDENTIFIER ON/OFF This option specifies the setting for use of double quotes. When this is on, double quotation mark is used as part of the SQL Server identifier (object name). This can be useful in situations in which identifiers are also SQL Server reserved words. In simple words when we have QUOTED IDENTIFIER ON, anything which is wrapped in double quotes becomes an object. E.g. -- The following will work SET QUOTED_IDENTIFIER ON GO CREATE DATABASE "Test1" GO -- The following will throw an error about Incorrect syntax near 'Test2'. SET QUOTED_IDENTIFIER OFF GO CREATE DATABASE "Test2" GO This feature is particularly helpful when we are working with reserved keywords in SQL Server. For example if you have to create a database with the name VARCHAR or INT or DATABASE you may want to put double quotes around your database name and turn on quoted identifiers to create a database with the such name. Personally, I do not think so anybody will ever create a database with the reserve keywords intentionally, as it will just lead to confusion. Here is another example to give you further clarity about how Quoted Idenifier setting works with SELECT statement. -- The following will throw an error about Invalid column name 'Column'. SET QUOTED_IDENTIFIER ON GO SELECT "Column" GO -- The following will work SET QUOTED_IDENTIFIER OFF GO SELECT "Column" GO Personally, I always use the following method to create database as it works irrespective of what is the quoted identifier’s status. It always creates objects with my desire name whenever I would like to create. CREATE DATABASE [Test3] I believe the future of the quoted identifier on or off is useful in the real world when we have script generated from another database where this setting was ON and we have to now execute the same script again in our environment again. Question to you - I personally have never used this feature as I mentioned earlier. I believe this feature is there to support the scripts which are generated in another SQL Database or generate the script for other database. Do you have a real world scenario where we need to turn on or off Quoted Identifiers.

  • Adjusting the Score on Oracle Text search results

    - by Kyle Hatlestad
    When you sort the results of a search by Score using OracleTextSearch as the search engine in WebCenter Content, the results coming back are based on the relevancy on the document.  In theory, the more relevant the search term is to the document, the higher ranked Score it should receive.  But in practice, the relevancy score can seem somewhat of a mystery.  It's not entirely clear how it ranks the importance of some documents over others based on the search term.  And often times, once a word appears a certain number of times within a document, the Score simply maxes out at 100 and the top results can be difficult to discern from one another.  Take for example the search for 'vacation' on this set of documents: Out of 7 results, 6 of them have a Score of '100' which means they are basically ranked the same.  This doesn't make the sort by Score very meaningful.   Besides sorting by relevance, you can also tell Oracle Text to sort by occurrence.  In that case, it is a much more predictable result in how they would be ranked. And for many cases provide a more meaningful sorting of results then relevance. To change this takes a small component change to the SearchOperatorMap resource.  By default, the query used for full-text searching looks like: <td>(ORACLETEXTSEARCH)fullText</td> <td>DEFINESCORE((%V), RELEVANCE * .1)</td> <td>text</td> Overriding this resource and changing it to: <td>(ORACLETEXTSEARCH)fullText</td> <td>DEFINESCORE((%V), OCCURRENCE * .01)</td>  <td>text</td> will force it to now use occurrence (note the change in scale to .01 as well).  So running the same search and sort options as the example above, the results come out quite a bit differently: In this case, there is a clear understanding of how the items rank.   And generally, if the search term appears 3 times more in one document then another, it's got a better chance of being a document I'm interested in.  You may or may not feel the relevance ranking is better then the search term occurrence, but this provides the opportunity to try an alternate method that might work better for your results.  A pre-built component is available for download here. There is one caveat in using this method.  The occurrence ranking also maxes out at 100, so if a search term is in the document more then that, the Score result will stay at 100.
