  • New "How do I ..." series

    - by Maria Colgan
    Over the last year or so the Optimizer development team has presented at a number of conferences and we got a lot of questions that start with "How do I ...". Where people were looking for a specific command or set of steps to fix a problem they had encountered. So we thought it would be a good idea to create a series of small posts that deal with these "How do I" question directly. We will use a simple example each time, that shows exactly what commands and procedures should be used to address a given problem. If you have an interesting "How do I .." question you would like to see us answer on the blog please email me and we will do our best to answer them! Watch out for the first post in this series which addresses the problem of "How do I deal with a third party application that has embedded hints that result in a sub-optimal execution plan in my environment?"

  • New and Improved Patch for FRM-40654 Errors in Purchase Orders and Requisitions

    - by user793044
    Development has modified the code in purchase orders and requisition forms to prevent error FRM-40654 when there are trailing spaces in the tables for most of the fields.  After applying the patch, the form will still display the error but a requery will allow you to save the transaction. For the scenarios not covered in the fix, the FND log will now display the specific field that causes the error.  This an example of the FND log for one document where the note_to_vendor has trailing spaces: Form note_to_vendor oldvalue Database  note_to_vendor newvalue Failed first if statement when comparing fields FRM-40654: Record has been updated. Requery block to see change. This new patch includes the fix in Patch 14204845:"In Oracle Purchasing, leading or trailing spaces in po lines data was resulting in errors".  For more information on FRM-40654 errors see the patching section of Note 1203796.1. Be proactive and apply Patch 14479586:R12.PO.B for 12.1.3 or Patch 14569747 for 11.5.10 now!

  • URL subfolder rewrite without server access

    - by Duke03
    I am having trouble with the following. I have a site in development that has every link on the site pointing to the wrong folder. Example: example.com/en/home/, a site link goes to example.com/en/, which throws a 404. Now the way the system is setup requires server access but I do not have that and I/S is backlogged with requests and will take a week. But I still need to develop the site. So is there a way to have the browser recognize when example.com/en/ is clicked then automatically redirect it to example.com/en/home so it bypasses the 404 and I can actually work. Im looking for anything that gets the job done. I am considering developing a Chrome app to do this but that would mean a shit ton of overtime and more work I don't want to do. Is there a easier way of doing this?

  • Working With Files in Dreamweaver

    Your web files have special needs because anytime you move or delete a file, it has an effect on other files that are linked to it. So, Dreamweaver also has file management tasks related to the web development environment. Dreamweaver keeps a record of all the links on your site. (Remember that the code for a photo is also a link.) Then when you move, Dreamweaver will ask if you want to update the other pages that link to that file. If you delete a file, Dreamweaver will warn you, if there are other pages using that file. Dreamweaver is actually a package of programs and one of them does the file management tasks.

  • Is there an opposite for the term "Backporting"?

    - by Avian00
    As I understand, the term "Backporting" is used to describe a fix which is applied in a future version which is also ported to a previous version. Wikipedia definition is as follows: Backporting is the action of taking a certain software modification (patch) and applying it to an older version of the software than it was initially created for. It forms part of the maintenance step in a software development process... For example: A problem is discovered and fixed in V2.0. The same fix is ported and applied to V1.5. What is the term when this is done in the opposite direction? The problem is discovered and fixed in V1.5. The same fix is ported and applied to V2.0. Would the term "Backporting" still apply? Or is there a term such as "Forwardporting" (which amusingly sounds a lot like "Port Forwarding")?

  • Frameworks for targetting multiple environments

    - by Werlang
    What should drive the decision behind doing development upon one or more than one framework? For instance, an ERP is (mostly) run on a Windows station. It leverages full access to device's resources, like printers, barcode readers, fingerprint readers and the like. It's usually more responsive and easier do develop with. That being said, some parts of it must be accessed exclusively in self-service mode, by enterprise's customers, suppliers and partners. This could be accomplished with smartphones, tablets, or even desktops running a web browser. What are the economics behind that? Should two team be kept, each one doing work upon its own framework? Or the most permissive framework should be chosen? Should I care something other than HTML technologies? Should I consider native technology for each device?

  • After power manager reinstall

    - by tuxi
    I had checking battery state hanging I solved it with the help of an answer from this site: sudo apt-get --reinstall install gnome-power-manager But now my left windows bar is rigid, it does not disappear on wide screen. EDIT Also in most of applications, characters are white. What could be the problem? and what should I do? 2ND EDIT My ubuntu is 12.04 LTS. I was trying to install some packages for dependencies of allegro game development library, one of the packages was libwxgtk2.8-0, after that a red cross appeared near user name and clock. Then computer became frozen and i had to remove my battery. I know it is a very bad thing. Then when i try to restart my computer, it could not start, it was waiting on black screen with line: Checking battery state... Then i run the above command. Computer could start but characters are white.

  • What steps should be taken to ensure that an open source database gets ready for production?

    - by I_like_traffic_lights
    I am considering using GridSQL in a production environment. However, I do have some indications that it is not ready. One is that it got excluded by the offering of EnterpriseDB a while ago, and the forums seem to report a few wrong results and relatively severe bugs. The alternatives to GridSQL, however cost around 100.000$ to buy, so I was thinking to utilize some of this money to ensure that GridSQL gets ready for production. At the same time, I could risk spending 50.000$ and months of work on the development of GridSQL, just to discover that the design was flawed and that a complete rewrite is needed. Then I would have to buy the commercial alternatives to GridSQL and the existence of my startup would be at risk. Question What steps would you take to ensure that there is as little risk as possible that the worst case scenario described above would happen? It is unrealistic that I could do much testing nor code review/coding myself (I am also not the best developer), so please describe where to find the guys that would need to do the work.

  • Will javascript be in the HTML5 standard

    - by Robz
    I'm pretty new to the web development scene, and I just want to be absolutely clear on this because I've read a few conflicting statements. I was under the impression that "html5" is a particular way of constructing xml to represent data for a webpage and "javascript" is a programming language that runs as client-side code in the browser. But left and right I see APIs for javascript (workers, geolocation, local storage, etc.) being referred to as an "html5 technology". Wikipedia says that html5 doesn't have a standard yet, so I can't look it up to see if it somehow mandates stuff about javascript. So will APIs for javascript somehow be apart of the html5 standard? Or has it become a common bad practice to label javascript APIs "html5 technology"?

  • How do you usually manage callbacks in Java using Swing library?

    - by none
    I'm quite new to the Java Swing programming, and GUI development as well. As a beginner, I'm currently reading Design Pattern, but finding what I'm looking for is quite hard, most of the times. So far, I've never had huge problems defining a view hierarchy - I just use to subclass component from component. But the hard-to-do here is how managing callbacks, which often become hard to maintain due to the hard code. During my last projects, I tried to separate GUI, Listener and Callbacker objects which cooperated together, but in this way it was really hard adding new features. So, which kind of best patterns or best practices do you tend to use when trying to maintain, add new features or even worst avoid to hard-code classes which manage callbacks method in this kind of frameworks (mainly Java Swing)?

  • Windows 8 Location Services

    - by ryanabr
    I spent the afternoon with the Geolocator object in the WinRT and Widows 8 platform. I have also been working with doing Windows Phone 7 development, and first had to wrap my head around the fact that while similar, it is not the same as the GeoCoordinateWatcher that environment. I found a nice example here http://code.msdn.microsoft.com/windowsapps/Geolocation-2483de66 But the behavior of my app wasn’t the same. Once you ensure that location services is enabled by following these instructions: http://msdn.microsoft.com/en-us/library/windows/desktop/hh768219.aspx Location Services was still disabled. From everything I read, it sounded like the first time you try to use the Geolocator object, the user would be prompted to allow to “Access to your location”. After nosing around I found the issue. You need to add the location service as a Capability in the Package.appxmanifest file: After checking the box, I was prompted to allow access to location services as expected the first time I needed to use it.

  • MVVM application architecture, where to put dependency injection configuration class, BusinessLayer and Common interfaces?

    - by gt.guybrush
    Planning my architecture for an MVVM application I come to this: MyApp.UI View MyApp.BusinessLayer ViewModel MyApp.DataAccessLayer RepositoryImplEF MyApp.DomainLayer DomainObject RepositoryInterface MyApp.Common Logging Security Utility (contains some reflection method used by many levels) CustomException MyApp.UnitTest I was inspired by Domain-driven-desing, test-driven-development and onion architecture but not sure to have done all well. I am not sure of a couple of things: where to put dependency injection configuration class? In the common project? where to put BusinessLayer interfaces? in Domain layer? where to put Common interfaces? in Domain layer? But Common in referenced from domain (for some reflection utilities and for DI if the response to 1. is yes) and circular reference isn't good

  • Is a function plotter a legitimate use of eval() in JavaScript?

    - by moose
    From PHP development I know that eval is evil and I've recently read What constitutes “Proper use” of the javascript Eval feature? and Don't be eval. The only proper use of eval I've read is Ajax. I'm currently developing a visualization tool that lets users see how polynomials can interpolate functions: Example Code on GitHub I use eval for evaluation of arbitrary functions. Is this a legitimate use of eval? How could I get rid of eval? I want the user to be able to execute any function of the following forms: a x^i with a,i in R sin, cos, tan b^x with b in R any combination that you can get by adding (e.g. x^2 + x^3 + sin(x)), multiplying (e.g. sin(x)*x^2) or inserting (e.g. sin(x^2))

  • Am I personally liable for bugs in medical software I've developed as an employee? [closed]

    - by user466406
    Some background: I'm employed at a small, Australia-based web agency that is dipping it's toe into Mobile Application development (iOS). The project that I'm working on provides a way for users to save medication dosage information which is sync'd with a backend server. Users must agree to ToS, Disclaimer etc before using the application. This is my first iOS application, and the project is currently over budget. As a result, management is not devoting the resources to Q&A and is pushing instead for more features. I am an employee of the agency, that has been contracted by a non-for-profit. The application will probably be released under our agency's name, but we also have the option of releasing it as the not-for-profit. My question is, if there are bugs found in the application, and as a result a user takes an incorrect dosage of a medication, am I personally liable? Is there anything that I can or should do in order to protect myself personally?

  • Ubuntu on low powered laptop

    - by zkent
    First off, I am new to Ubuntu. I come from a Windows background (DOS before that) and am loving it so far. I installed it on an older Dell laptop that I wanted to get another year out of. I set this machine up primarily as a LAMP development machine for a project I am working on. The machine is a Vostro 1500 and it has 4GB RAM (maxed) and an upgraded hard drive. I can't watch YouTube videos for long before it starts to overheat and start acting sporadic. I can live without YouTube but every so often the application switching (alt-tab) gets slower and begins not showing all applications and the Dash home quits displaying properly. I am sure I am asking a lot of this old machine. What I really want to know is: are there any settings in Ubuntu that allow me to lower the graphic effects (fade-ins, transparencies, fancy transitions, etc) that would be less taxing on the video card?

  • How do developers find the time to stay on top of latest technologies?

    - by u2sonderzug
    I was a freelance web developer until circa 2004 when I started going down the management route but have decided to try to get back into development again (specifically JavaScript and HTML5 web/mobile web apps) and I really get the impression to be truly good at these and similar fast moving technologies a constant amount of time is required to be set aside to invest in getting better at existing skills in addition to learning new skills. I understand right now since I am getting back into things there is a pretty steep learning curve, but seeing how good many guys are out there - the only way I see of getting up there is putting in a serious amount of time. For those working as fulltime developers, what I am trying to understand is this - on most days, how much time in the office is spent actually grinding out code compared to learning/research. I could easily spend 2-4 hours daily getting on top of the best ways to go about doing things. Do most good developers who are employed full time invest significant hours outside of work sharpening their skills? Or maybe I'm looking at all of this completely wrong?

  • Suggestion for a Non-CSE developer

    - by Md.lbrahim
    Due to financial problems, I couldn't go for CSE in my country and had to settle for a BCIS honors degree. Now, after quite some time, when I want to go for a higher position in software development then I get asked about algorithms and basics that I have missed back in uni. This is affecting my chances of getting selected and I cannot afford that any longer. My question would be that what you would suggest smn like me to do in order to cover the 'basics' without any university or educational institute e.g. books,learn C++,etc? Any suggestion (including -ve) is welcomed and appreciated.

  • Release roadmap with scrum

    - by SyBer
    I need to prepare an internal product release road-map for product being built via scrum methodology, and have some difficulty correlating sprints to the road-map. The main problem is that as I don't have effort estimations for every story, because these prepared immediately before each sprint, so I don't know what will make into which sprint. I'm fine with changing the road-map as the development goes on, but need it to give at least some indication when things planned to be released. So what would be the best way to do this, other then guestimating the whole backlog? Thanks for any idea.

  • How do I secure a Tomcat installation?

    - by spangeman
    I have installed tomcat on my Ubuntu Home 11.10 system and can successfully access the test page online after port forwarding on 8080 within my router. I have not made any other changes to the router, Ubuntu or the tomcat install, everything else has remained standard. I intend on using this to play around with Java Servlets and basic web development for my own personal use. What steps, if any, would you suggest I take to ensure this is secure? Should I change anything within the Tomcat configuration? This seemed like a good idea to limit access - http://www.seankilleen.com/2010/09/how-to-allow-only-specific-ip-addresses_30.html But I am open to any other recommendations.

  • Workflow of sharing code for small teams

    - by Mihalis Bagos
    Problem is, we have developed a small CMS, that is different per implementation (currently). Of course development of this is never complete. Sometimes, we are working on more than one project that implements it (by copying-pasting the code files of the CMS to each project), and we add a new feature that we want to share on other projects as well (these can be small ones too, ie a custom ajax JSON controller - we use MVC) What we want to do is quickly and uniformly share the code with all other projects, via a version control system (or something similar), and generally organize the workflow as we know this isn't a very good workflow that we have. What would you suggest? Also, at the momment, the software we use is Visual Studio 2010, so we are strongly considering TFS, but even if we get it we still don't know the ideal workflow, or even if TFS supports what we want to do. Edit: Also note, we have specific implementations that have modifications over the CMS base that we want to KEEP only in the project area. (ie: a specific feature that we DONT want to share with the base CMS code)
