  • How to choose an agile methodology?

    - by Christophe Debove
    I'm working in a little firm about 10 developpers, we are working a kind of agile way but knowledgeless and without formalism. I think be aware of what are agile method, what can they afford to us, may render more productive our products. However there is a lot of agile method, which could be the simplest to "learn"?

  • After changing Compiz configuration, I can't use account

    - by Dumitru Cristian
    I think I have made some changes in Compiz and now I can't see anything on the screen when I log in with a user. For the other users everything is OK. Is there any possibility to reset to default compiz? All I can do logged in as the user with problems is pressing ctrl-alt-F2, and then I have to log in a terminal. I'm not at all a power user, so I apologies if my question is not very clear. Thanks in advance

  • Ubuntu 12.04 LTS initramfs-tools dependency issue

    - by Mike
    I know this has been asked several times, but each issue and resolution seems different. I've tried almost everything I could think of, but I can't fix this. I have a VM (VMware I think) running 12.04.03 LTS which has stuck dependencies. The VM is on a rented host, running a live system so I don't want to break it (further). uname -a Linux support 3.5.0-36-generic #57~precise1-Ubuntu SMP Thu Jun 20 18:21:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Some more: sudo apt-get update [sudo] password for tracker: Reading package lists... Done Building dependency tree Reading state information... Done You might want to run ‘apt-get -f install’ to correct these. The following packages have unmet dependencies. initramfs-tools : Depends: initramfs-tools-bin (< 0.99ubuntu13.1.1~) but 0.99ubuntu13.3 is installed E: Unmet dependencies. Try using -f. sudo apt-get install -f Reading package lists... Done Building dependency tree Reading state information... Done Correcting dependencies...

Y dpkg: dependency problems prevent configuration of initramfs-tools: initramfs-tools depends on initramfs-tools-bin (<< 0.99ubuntu13.1.1~); however: Version of initramfs-tools-bin on system is 0.99ubuntu13.3. dpkg: error processing initramfs-tools (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates it's a follow-up error from a previous failure. dpkg: dependency problems prevent configuration of apparmor: apparmor depends on initramfs-tools; however: Package initramfs-tools is not configured yet. dpkg: error processing apparmor (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates it's a follow-up error from a previous failure. Errors were encountered while processing: initramfs-tools apparmor E: Sub-process /usr/bin/dpkg returned an error code (1) If I look at the policy behind initramfs-tools / bin I get: apt-cache policy initramfs-tools initramfs-tools: Installed: 0.99ubuntu13.1 Candidate: 0.99ubuntu13.3 Version table: 0.99ubuntu13.3 0 500 http://gb.archive.ubuntu.com/ubuntu/ precise-updates/main amd64 Packages *** 0.99ubuntu13.1 0 100 /var/lib/dpkg/status 0.99ubuntu13 0 500 http://gb.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages apt-cache policy initramfs-tools-bin initramfs-tools-bin: Installed: 0.99ubuntu13.3 Candidate: 0.99ubuntu13.3 Version table: *** 0.99ubuntu13.3 0 500 http://gb.archive.ubuntu.com/ubuntu/ precise-updates/main amd64 Packages 100 /var/lib/dpkg/status 0.99ubuntu13 0 500 http://gb.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages So the issue seems to be I have 0.99ubuntu13.3 for initramfs-tools-bin yet 0.99ubuntu13.1 for initramfs-tools, and can't upgrade to 0.99ubuntu13.3. I've performed apt-get clean/autoclean/install -f/upgrade -f many times but they won't resolve. I can think of only 2 other 'solutions': Edit the dpkg dependency list to trick it into doing the installation with a broken dependency. This seems very dodgy and it would be a last resort Downgrade both initramfs-tools and initramfs-tools-bin to 0.99ubuntu13 from the precise/main sources and hope that would get them in step. However I'm not sure if this will be possible, or whether it would introduce more issues. I'm not sure how this situation arise in the first place. /boot was 96% full; it's now 56% full (it's tiny - 64MB ... this is what I got from the hosting company). Can anyone offer advice please?

  • What are the design decisions involved in choosing how to expose a Java web application?

    - by Gary Rowe
    There are many ways to expose a Java web application to the consumer: application container (JBoss etc), servlet container (Tomcat etc), OSGi (Knopflerfish etc), self-executable WAR (Winstone etc) and so on. Are there any clear considerations where one approach should be favoured over another? As an example, could a collection of self-executable WARs running as raw Unix processes outperform the same applications deployed within Tomcat taking into account administration and scalability concerns?

  • Learn more about MDX every day

    - by Marco Russo (SQLBI)
    I started learning MDX in 1999 and after so many years of using it and teaching it to other people, I still discover something new every day. Not only because I use it in strange ways (well, this doesn’t happen every day, at least!) but because there are other interesting information to read. Jeffrey Wang just published another interesting blog about data prefetching in MDX, which explains very well some strange behavior that sometime I observed in some customer cube. I never had a clear explanation...(read more)

  • Clarity is important, both in question and in answer.

    - by gerrylowry
    clarity is important ... i'm often reminded of the Clouseau movie in which Peter Sellers as Chief Inspector Clouseau asks a hotel clerk "Does your dog bite?" ... the clerk answers "no" ... after Clouseau has been bitten by the dog, he looks at the hotel clerk who says "That's not my dog".  Clarity is important, both in question and in answer. i've been a member of forums.asp.net since 2008 ... like many of my peers at forums.asp.net, i've answered my fair share of questions. FWIW, the purpose of this, my first web log post to http://weblogs.asp.net/gerrylowry is to help new members ask better questions and in turn get better answers. TIMTOWTDI  =.  there is more than one way to do it imho, the best way to ask a question in any forum, or even person to person, is to first formulate your question and then ask yourself to answer your own question. Things to consider when asking (the more complete your question, the more likely you'll get the answer you require): -- have you searched Google and/or your favourite search engine(s) before posting your question to forums.asp.net; examples: site:msdn.microsoft.com entity framework 5.0 c#http://lmgtfy.com/?q=site%3Amsdn.microsoft.com+entity+framework+5.0+c%23 site:forums.asp.net MVC tutorial c#http://lmgtfy.com/?q=site%3Aforums.asp.net+MVC+tutorial+c%23 -- are you asking your question in the correct forum?  look at the forums' descriptions at http://forums.asp.net/; examples: Getting Started If you have a general ASP.NET question on a topic that's not covered by one of the other more specific forums - ask it here. MVC Discussions regarding ASP.NET Model-View-Controller (MVC) C# Questions about using C# for ASP.NET development Note:  if your question pertains more to c# than to MVC, choosing the C# forum is likely to be more appropriate. -- is your post subject clear and concise, yet not too vague? compare these three subjects (all three had something to do with GridView):     (1)    please help     (2)    gridview      (3)    How to show newline in GridView  -- have you clearly explained your scenario? compare:  my leg hurts   with   when i walk too much, my right knee hurts in the knee joint  compare:  my code does not work    with    when i enter a date as 2012-11-8, i get a FormatException -- have you checked your spelling, your grammar, and your English? for better or worse, English is the language of forums.asp.net ... many of the currently 170000++ forums.asp.net are not native speakers of English; that's okay ... however, there are times when choosing the more appropriate words will likely get one a better answer; fortunately, there are web tools to help you formulate your question, for example, http://translate.google.com/.  -- have you provided relevant information about your environment? here are a few examples ... feel free to include other items to your question ... rule of thumb:  if you think a given detail is relevant, it likely is -- what technology are you using?    ASP.NET MVC 4, ASP.NET MVC 3, WebForms, ...  -- what version of Visual Studio are you using?  vs2012 (ultimate, professional, express), vs2010, vs2008 ... -- are you hosting your own website?  are you using a shared hosting service? -- are you experience difficulties in just one browser? more than one browser? -- what browser version(s) are you using?   ie8? ie9? ... -- what is your operating system?     win8, win7, vista, XP, server 2008 R2 ... -- what is your database?   SQL Server 2008 R2, ss2005, MySQL, Oracle, ... -- what is your web server?  iis 7.5, iis 6, .... -- have you provided enough information for someone to be able to answer your question? Here's an actual example from an O.P. that i hope is self-explanatory: I'm trying to make a simple calculator when i write the code in windows application it worked when i tried it in web application it doesn't work and there are no errors what should i do ??!! -- have you included unnecessary information? more than once, i've seen the O.P. (original post, original poster) include many extra lines of code that were not relevant to the actual question; the more unnecessary code that you include, the less likely your volunteer peers will be motivated to donate their time to help you. -- have you asked the question that you want answered? "Does this dog bite?" -- are your expectations reasonable? -- generally, persons who are going to answer your questions are your peers ... they are unpaid volunteers ... -- are you looking for help with your homework, work assignment, or hobby? or, are you expecting someone else to do your work for you?  -- do you expect a complete solution or are you simply looking for guidance and direction? -- you are likely to get more help by first making a reasonable effort to help yourself first Clarity is important, both in question and in answer. if you are answering someone else's question, please remember that clear answers are just as important as clear questions; would you understand your own answer? Things to consider when answering: -- have you tested your code example?  if you have, say so; if you've not tested your code example, also say so -- imho, it's okay to guess as long as you clearly state that you're guessing ... sometimes a wrong guess can still help the O.P. find her/his way to the right answer -- meanness does not contribute to being helpful; sometimes one may become frustrated with the O.P. and/or others participating in a thread, if that happens to you, be kind regardless; speaking from my own experience, at least once i've allowed myself to be frustrated into writing something inappropriate that i've regretted later ... being a meany does not feel good ... being kind and helpful feels fantastic! Tip:  before asking your question, read more than a few existing questions and answers to get a sense of how your peers ask and answer questions. Gerry P.S.:  try to avoid necroposting and piggy backing. necroposting is adding to an old post, especially one that was resolved months ago. piggy backing is adding your own question to someone else's thread.

  • Adding Actions to a Cube in SQL Server Analysis Services 2008

    Actions are powerful way of extending the value of SSAS cubes for the end user. They can click on a cube or portion of a cube to start an application with the selected item as a parameter, or to retrieve information about the selected item. Actions haven't been well-documented until now; Robert Sheldon once more makes everything clear.

  • Windows Azure Recipe: Consumer Portal

    - by Clint Edmonson
    Nearly every company on the internet has a web presence. Many are merely using theirs for informational purposes. More sophisticated portals allow customers to register their contact information and provide some level of interaction or customer support. But as our understanding of how consumers use the web increases, the more progressive companies are taking advantage of social web and rich media delivery to connect at a deeper level with the consumers of their goods and services. Drivers Cost reduction Scalability Global distribution Time to market Solution Here’s a sketch of how a Windows Azure Consumer Portal might be built out: Ingredients Web Role – this will host the core of the solution. Each web role is a virtual machine hosting an application written in ASP.NET (or optionally php, or node.js). The number of web roles can be scaled up or down as needed to handle peak and non-peak traffic loads. Database – every modern web application needs to store data. SQL Azure databases look and act exactly like their on-premise siblings but are fault tolerant and have data redundancy built in. Access Control (optional) – if identity needs to be tracked within the solution, the access control service combined with the Windows Identity Foundation framework provides out-of-the-box support for several social media platforms including Windows LiveID, Google, Yahoo!, Facebook. It also has a provider model to allow integration with other platforms as well. Caching (optional) – for sites with high traffic with lots of read-only data and lists, the distributed in-memory caching service can be used to cache and serve up static data at higher scale and speed than direct database requests. It can also be used to manage user session state. Blob Storage (optional) – for sites that serve up unstructured data such as documents, video, audio, device drivers, and more. The data is highly available and stored redundantly across data centers. Each entry in blob storage is provided with it’s own unique URL for direct access by the browser. Content Delivery Network (CDN) (optional) – for sites that service users around the globe, the CDN is an extension to blob storage that, when enabled, will automatically cache frequently accessed blobs and static site content at edge data centers around the world. The data can be delivered statically or streamed in the case of rich media content. Training Labs These links point to online Windows Azure training labs where you can learn more about the individual ingredients described above. (Note: The entire Windows Azure Training Kit can also be downloaded for offline use.) Windows Azure (16 labs) Windows Azure is an internet-scale cloud computing and services platform hosted in Microsoft data centers, which provides an operating system and a set of developer services which can be used individually or together. It gives developers the choice to build web applications; applications running on connected devices, PCs, or servers; or hybrid solutions offering the best of both worlds. New or enhanced applications can be built using existing skills with the Visual Studio development environment and the .NET Framework. With its standards-based and interoperable approach, the services platform supports multiple internet protocols, including HTTP, REST, SOAP, and plain XML SQL Azure (7 labs) Microsoft SQL Azure delivers on the Microsoft Data Platform vision of extending the SQL Server capabilities to the cloud as web-based services, enabling you to store structured, semi-structured, and unstructured data. Windows Azure Services (9 labs) As applications collaborate across organizational boundaries, ensuring secure transactions across disparate security domains is crucial but difficult to implement. Windows Azure Services provides hosted authentication and access control using powerful, secure, standards-based infrastructure. See my Windows Azure Resource Guide for more guidance on how to get started, including links web portals, training kits, samples, and blogs related to Windows Azure.

  • Code review recommendations and Code Smells

    - by Michael Freidgeim
    Some time ago Twitter told that I am similar to Boris Lipschitz . Indeed he is also .Net programmer from Russia living in Australia. I‘ve read his list of Code Review points and found them quite comprehensive. A few points  were not clear for me, and it forced me for a further reading.In particular the statement “Exception should not be used to return a status or an error code.” wasn’t fully clear for me, because sometimes we store an exception as an object with all error details and I believe it’s a valid approach. However I agree that throwing exceptions should be avoided, if you expect to return error as a part of a normal flow. Related link: http://codeutopia.net/blog/2010/03/11/should-a-failed-function-return-a-value-or-throw-an-exception/ Another point slightly puzzled me“If Thread.Sleep() is used, can it be replaced with something else, ei Timer, AutoResetEvent, etc” . I believe, that there are very rare cases, when anyone using Thread.Sleep in any production code. Usually it is used in mocks and prototypes.I had to look further to clarify “Dependency injection is used instead of Service Location pattern”.Even most of articles has some preferences to Dependency injection, there are also advantages to use Service Location. E.g see http://geekswithblogs.net/KyleBurns/archive/2012/04/27/dependency-injection-vs.-service-locator.aspx. http://www.cookcomputing.com/blog/archives/000587.html  refers to Concluding Thoughts of Martin Fowler The choice between Service Locator and Dependency Injection is less important than the principle of separating service configuration from the use of services within an applicationThe post had a link to excellent article Code Smells of Jeff Atwood, but the statement, that “code should not pass a review if it violates any of the  code smells” sound too strict for my environment. In particular, I disagree with “Dead Code” recommendation “Ruthlessly delete code that isn't being used. That's why we have source control systems!”. If there is a chance that not used code will be required in a future, it is convenient to keep it as commented or #if/#endif blocks with appropriate explanation, why it could be required in the future. TFS is a good source control system, but context search in source code of current solution is much easier than finding something in the previous versions of the code.I also found a link to a good book “Clean Code.A.Handbook.of.Agile.Software”

  • OOP - Composition, Components and Composites Example?

    - by coder3
    I've been reading a bit about OOP in relation to Composition, Components and Composites. I believe I understand the fundamental principle (not sure). Can some one please provide a code example of a person or car (both have many properties) using Composition, Components and Composites. I think seeing it in code would clear up the confusion I have regarding this pattern. Preferably in Java or PHP - many thanks!

  • XNA - Moving Background Calculations

    - by Jesse Emond
    Hi, My question is relatively hard to explain(for me, at least), so I'll go one step at a time and just tell me in the comments if it's not clear enough. So I'm making a "Defend Your Castle" type 2D game, where two players own a castle and create units that will move horizontally to try to destroy the opponent's base. Here's a screenshot of the game: The distance between both castles is much bigger in a real game though, bigger than the screen's width actually. Because the distance is bigger than the screen's width, I had to implement a simple 2D camera: Camera2D, which only holds a Location Vector2 (and I always make sure this camera is within the field area). Then, I just move all the game elements(castles, units, health bars) by that location, so that if a unit is at (5, 0), and the camera's location is (5, 0), then the unit's position will be moved by 5 units to the left, making it (0, 0) on the screen. At first, I simply used a static background with mountains and clouds(yeah, those are supposed to be mountains and clouds). Obviously, this looked awful: when you moved the camera, the background would stay immobile. Instead, I'd like to make a moving background, kind of a "scrolling" one. But rather than making a background with the same width as the distance between the castles, I'd like to make one that is a little bit smaller(but still bigger than the screen's width). I thought this would create an effect of "distance" with the background(but it might just look awful, too). Here's the background I'm testing with: I tried different ways, but none of them seems to work. I tried this: float backgroundFieldRatio = BackgroundTexture.Width / fieldWidth;//find the ratio between the background and the field. float backgroundPositionX = -cam.Location.X * backgroundFieldRatio;//move the background to the left When I run this with fieldWith = 1600, BackgroundTexture.Width = 1500 and while looking at the rightmost area, the background is offset to the left by a too big amount, and we can see the black clear color in the back, as you can see here: I hope I explained properly what I'm trying to achieve. Thank you for your time. Note: I didn't know what to look for on Google, so I thought I'd ask here.

  • BizTalk 2009 - SQL Server Job Configuration

    - by StuartBrierley
    Following the installation of Biztalk Server 2009 on my development laptop I used the BizTalk Server Best Practice Analyser which highlighted the fact that two of the SQL Server Agent jobs that BizTalk relies on were not running successfully.  Upon investigation it turned out that these jobs needed to be configured before they would run successfully. To configure these jobs open SQL Server Management Studio, expand SQL Server Agent > Jobs and double click on the appropriate job.  Select Steps and then edit the appropriate entries. Backup BizTalk Server (BizTalkMgmtDb) This job is comprised of three steps BackupFull, MarkAndBackupLog and ClearBackupHistory. BackupFull exec [dbo].[sp_BackupAllFull_Schedule] ‘d’ /* Frequency */,‘BTS’ /* Name */,‘<destination path>’ /* location of backup files */ The frequency here is set/left as daily The name is left as BTS You must provide a full destination path for the backup files to be stored. There are also two optional parameters: A flag that controls if the job forces a full backup if a partial backup fails A parameter to control the time of day to run the full backup; the default is midnight UTC time For example: exec [dbo].[sp_BackupAllFull_Schedule] ‘d’ /* Frequency */,‘BTS’ /* Name */,‘<destination path>’ /* location of backup files */ , 0, 22 MarkAndBackUpLog exec [dbo].[sp_MarkAll] ‘BTS’ /* Log mark name */,’<destination path>’  /*location of backup files */ You must provide a destination path for the log backups. Optionally you can also add an extra parameter that tells the procedure to use local time: exec [dbo].[sp_MarkAll] ‘BTS’ /* Log mark name */,’<destination path>’  /*location of backup files */ ,1 Clear Backup History exec [dbo].[sp_DeleteBackupHistory] @DaysToKeep=7 This will clear out the instances in the MarkLog table older than 7 days.    DTA Purge and Archive (BizTalkDTADb) This job is comprised of a single step. Archive and Purge exec dtasp_BackupAndPurgeTrackingDatabase 0, --@nLiveHours tinyint, 1, --@nLiveDays tinyint = 0, 30, --@nHardDeleteDays tinyint = 0, null, --@nvcFolder nvarchar(1024) = null, null, --@nvcValidatingServer sysname = null, 0 --@fForceBackup int = 0 Any completed instance that is older than the live days plus live hours will be deleted, as will any associated data. Any data older than the HardDeleteDays will be deleted - this means that those long running orchestration instances that would otherwise never be purged will at some point have their data cleared down while allowing the instance to continue, thus preventing the DTA databse from growing indefinitely.  This should always be greater than the soft purge window. The NVC folder is the path for the backup files, if this is null the job will not run failing with the error : DTA Purge and Archive (BizTalkDTADb) Job failed SQL Server Management Studio, job activity monitor, view history The @nvcFolder parameter cannot be null. Archive and Purge step How long you choose to keep instances in the Tracking Database is really up to you. For development I have set this up as: exec dtasp_BackupAndPurgeTrackingDatabase 0, 1, 30, ’<destination path>’, null, 0 On a live server you may want to adjust these figures: exec dtasp_BackupAndPurgeTrackingDatabase 0, 15, 20, ’<destination path>’, null, 0

  • Stir Trek 2: Iron Man Edition

    Next month (7 May 2010) Ill be presenting at the second annual Stir Trek event in Columbus, Ohio. Stir Trek (so named because last year its themes mixed MIX and the opening of the Star Trek movie) is a very cool local event.  Its a lot of fun to present at and to attend, because of its unique venue: a movie theater.  And whats more, the cost of admission includes a private showing of a new movie (this year: Iron Man 2).  The sessions cover a variety of topics (not just Microsoft), similar to CodeMash.  The event recently sold out, so Im not telling you all of this so that you can go and sign up (though I believe you can get on the waitlist still).  Rather, this is pretty much just an excuse for me to talk about my session as a way to organize my thoughts. Im actually speaking on the same topic as I did last year, but the key difference is that last year the subject of my session was nowhere close to being released, and this year, its RTM (as of last week).  Thats right, the topic is Whats New in ASP.NET 4 how did you guess? Whats New in ASP.NET 4 So, just what *is* new in ASP.NET 4?  Hasnt Microsoft been spending all of their time on Silverlight and MVC the last few years?  Well, actually, no.  There are some pretty cool things that are now available out of the box in ASP.NET 4.  Theres a nice summary of the new features on MSDN.  Here is my super-brief summary: Extensible Output Caching use providers like distributed cache or file system cache Preload Web Applications IIS 7.5 only; avoid the startup tax for your site by preloading it. Permanent (301) Redirects are finally supported by the framework in one line of code, not two. Session State Compression Can speed up session access in a web farm environment.  Test it to see. Web Forms Features several of which mirror ASP.NET MVC advantages (viewstate, control ids) Set Meta Keywords and Description easily Granular and inheritable control over ViewState Support for more recent browsers and devices Routing (introduced in 3.5 SP1) some new features and zero web.config changes required Client ID control makes client manipulation of DOM elements much simpler. Row Selection in Data Controls fixed (id based, not row index based) FormView and ListView enhancements (less markup, more CSS compliant) New QueryExtender control makes filtering data from other Data Source Controls easy More CSS and Accessibility support Reduction of Tables and more control over output for other template controls Dynamic Data enhancements More control templates Support for inheritance in the Data Model New Attributes ASP.NET Chart Control (learn more) Lots of IDE enhancements Web Deploy tool My session will cover many but not all of these features.  Theres only an hour (3pm-4pm), and its right before the prize giveaway and movie showing, so Ill be moving quickly and most likely answering questions off-line via email after the talk. Hope to see you there! 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.

  • Is there an official Ubuntu free support team?

    - by João Pinto
    I have found that there is an "Ubuntu Support Team" at https://launchpad.net/~ubuntu-helpteam but I am not sure it's official or active. Please note that I am not referring to bug fixing support, I am referring to the broader OS support, with people available to engage users needing support with a problem and drive it to a proper resolution. Is there an official team for this purpose with a clear scope and activity plan ?

  • Optimize video filesize without quality loss

    - by user12015
    Is there a simple way (on the command line - I want to write a script which compresses all videos in a folder) to reduce the filesize of a video (almost) without quality loss? Is there a method which works equally well for different video format (mp4, flv, m4v, mpg, mov, avi)? I should mention that most of the videos I would like to compress are downloaded web-videos (mp4, flv), so it's not clear if there is much room for further compression.

  • 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.

  • What are the steps to grouping related classes into packages

    - by user2368481
    I've been googling this for some time, but what I haven't found are the clear steps needed to be taken to group related classes into packages in Java. In my case, I have about a number of .java files that I'd like to group into 3 packages according to the MVC pattern. One package for Model classes, one package for View classes and one package for Controller classes. I've identified which belong in what package, but not sure of the next step.

  • bug: deviation from requirements vs deviation from expectations

    - by user970696
    I am not clear on this one. No matter the terminology, in the end the software fault/bug causes (according to a lot of sources): Deviation from requirements Devation from expectations But if the expectations are not in requirements, then stakeholder could see a bug everywhere as he expected it to be like this or that..So how can I really know? I did read that specification can miss things and then of course its expected but not specified (by mistake).

  • Pidgin script with Python/ Get Focus Signal

    - by Mr Alles
    I am creating a script in Python to integrate Pidgin with Unity (12.04), I've managed to do the counting notifications system using the Launcher API. But I dont know what event or signal is activated when the conversation window gains focus (To clear the message counter). I've tried some of the signals available on the documentation of Pidgin but none of them worked. Is there any GTK(or anything) event that is triggered when the window chat gets focus?
