  • Wrong perspective is showing in Eclipse plugin project [closed]

    - by Arun Kumar Choudhary
    I am working in Eclipse Modeling Framework (Eclipse plugin development) in my project the tool(project i am working) provides three perspectives. 1.Accelerator Analyst perspective 2.Contract Validation and 3.Underwriter rules Editor... By default it starts with Contract validation perspective (As we define it within the plugin_customization.ini). However after switching to other perspective does not change the perspective shown... As all perspective (Class, Id and Name) is define only inside Plugin.XML as it is the task of org.eclipse.ui.perspective that that perspective name should be come forefront. Out of 10 7 times it is working fine but I am not getting why this is not working in that 3 cases. I am pasting my plugin.XML file <?xml version="1.0" encoding="UTF-8"?> <?eclipse version="3.0"?> <plugin> <extension id="RuleEditor.application" name="Accelerator Tooling"

  • Git Project Dependencies on GitHub

    - by VirtuosiMedia
    I've written a PHP framework and a CMS on top of the framework. The CMS is dependent on the framework, but the framework exists as a self-contained folder within the CMS files. I'd like to maintain them as separate projects on GitHub, but I don't want to have the mess of updating the CMS project every time I update the framework. Ideally, I'd like to have the CMS somehow pull the framework files for inclusion into a predefined sub-directory rather than physically committing those files. Is this possible with Git/GitHub? If so, what do I need to know to make it work? Keep in mind that I'm at a very, very basic level of experience with Git - I can make repositories and commit using the Git plugin for Eclipse, connect to GitHub, and that's about it. I'm currently working solo on the projects, so I haven't had to learn much more about Git so far, but I'd like to open it up to others in the future and I want to make sure I have it right. Also, what should my ideal workflow be for projects with dependencies? Any tips on that subject would also greatly appreciated. If you need more info on my setup, just ask in the comments.

  • How to decide on a price for the project as a freelancer

    - by Shekhar_Pro
    I have seen similar question on this SE site but none comes close to a sure shot answer and many are rather subjective. So i am taking a website as an example to be more objective for you to decide its development price i should quote for the complete work.I would like to have specific figures. In past I have developed many projects for my classmates (Computer science and few .net) when i was in college and there i just arbitrarily quoted the price i will take depending on my mood and customer's ability to pay.. usually ranging from Rs.500 (about $10 USD) to Rs. 1500 (about $30 USD). I have also developed few websites but that was open-source and free. But this time impressed by my work i have got a client that wants to get a website developed similar to this: [ http://www.jeetle.in/ ]. So taking this website as an example tell me how much should i charge for complete work from designing to payment gateway implementation (Excluding the charge the payment gateway provider will take). Few information you might like to consider. I am the only developer on this project if that makes any difference. And i would be using ASP.Net and MSSQL Express for server side processing and jQuery on client. Time period for development offered is about 4 to 6 Weeks. Its like i know my work but not how much I'm worth

  • Github Project Wiki: separate page filename from page title

    - by Marko Apfel
    Starting Point In a former version of a project wiki on Github was a separation between the page filename and page title. So we build up our Wiki in a manner, that some well defined prefixes in the filename describe the overall context of the particular page. Sample: At the page themselves we used a title-tag on top of the page to get the title in the rendered HTML-page. Here “= Tabelle: Anhänge bzw. Attachments” for the page with filename “data+table+Attachment”. This was rendered as We see: there is a file “data+table+Attachment” and a title-tag “= Tabelle: Anhänge bzw. Attachments” as well as a rendering with the title “Tabelle: Anhänge bzw. Attachments”. This was fine. Problem Now the Github-Wiki uses the title of the page as the filename and vice versa. This ends up in a cluttered file system and also in suppressing titles in the page themselves. So this page renders to As we could see: the title tag “= Organisation: IT-Infrastruktur” is not more rendered. Instead the filename “organisation+IT Infrastructure” is choosen as the title for the page. That sucks. Solution I reported this by Github again and hope for a fix.

  • [Kubuntu 14.04][Eclipse] (ADT) crashes at button OK from Project properties

    - by nouseforname
    Since i upgraded to kubuntu 14.04, my Eclipse crashes at different situations. Mostly i can "simulate" it when going to project properties and press ok. Then it always crashes.

Which actually doesn't cause any crahs it seems so far. So i have 3 options: accept crashes accept warnings (maybe the best choice) accept ugly design What can i do to solve this issue without changing the design settings?

  • Removing specific part of filename (what's after the second dash) for all files in a folder

    - by Bodo
    I use the command line utility youtube-dl to download videos from YouTube and make mp3s from them with avconv. I'm doing this under Ubuntu 14.04 and very happy with it. The utility downloads the files and saves them with the following name scheme: TITLE(artist-track)-ID.mp3 So an actual filename looks like: EPIC RAP BATTLE of MANLINESS-_EzDRpkfaO4.mp3 Some other file names in the folder look like: EPIC RAP BATTLE of MANLINESS-_EzDRpkfaO4.mp3 Martin Garrix - Animals (Official Video)-gCYcHz2k5x0.mp3 Stromae - Papaoutai-oiKj0Z_Xnjc.mp3 At first, this was no problem. It didn't bother me while listening to my music in Rhytmbox. But when moving to phone or other devices it is pretty confusing to see a so long name, and some players, like the Samsung ones, treat that last part (id after second dash) of the name as Album or something. I'd like to create a bash script that removes what's after the second dash in the name for all files, so it'll make them like this: From: Martin Garrix - Animals (Official Video)-gCYcHz2k5x0.mp3 To: Martin Garrix - Animals (Official Video).mp3 Is it also possible to instruct youtube-dl to exclude the ID from now on? I am currently downloading with the command: youtube-dl --extract-audio --audio-quality 0 --audio-format mp3 URL

  • 2D animations frames vs 3D animation for small indie project: timing considerations

    - by mm24
    pretty lame question but was wondering.. I am developing a 2D game using Cocos2D for iOS. The art work till now is all 2D (is a shooter game) but some of the characters would benefit of complex animations (eg. 20 frames). I feel a bit stupid because I came across only now that there is the chance to do 3D to 2D frames exporting and then to use them in Cocos2D. The thing that put me off on 3D gaming at first was that it takes more than one person in a team to do so properly (Illustrator, 3D modeller, 3D animator and programmer). Now I feel a bit stupid because having a 3D model I could do and modify the poses whenever I wanted (I should ask to the 3D animator which I guess would be time expensive). Instead now is me and two illustrators (as I require many frames per character). Is my impression that it would have been much longer right or not? Are there any other project management considerations that can be done on this? Sorry if for some this might be trivial but is my first "indie game developer experience".

  • NetBeans Hangs on New Project Creation

    - by Jason
    When creating a New Project in NetBeans, it hangs on the creation screen; Screenshot I'm running Netbeans 7.0.1 on Xubuntu 13.04. Java -version prints: java version "1.7.0_25" OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.13.04.2) OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode) /usr/lib/jvm/ contains the following folders; java-1.5.0-gcj-4.7-amd64 java-6-openjdk-amd64 java-7-openjdk-common java-1.6.0-openjdk-amd64 java-6-openjdk-common java-1.7.0-openjdk-amd64 java-7-openjdk-amd64 I tried editing /usr/share/netbeans/7.0.1/etc/netbeans.conf with the following (as was suggested in another post); netbeans_jdkhome="/usr/lib/jvm/java-7-openjdk-amd64/jre/" But that didn't work. Instead, NetBeans then presented an error on the loading splash when it reached "Turning on Modules..." claiming the JDK was missing. Both NetBeans and the OpenJDK Java 7/6 Runtimes were installed through the Ubuntu Software Centre. I've also tried uninstalling and reinstalling both Java and NetBeans. Any help would be greatly appreciated, thanks!

  • Inheritance vs containment while extending a large legacy project

    - by Flot2011
    I have got a legacy Java project with a lot of code. The code uses MVC pattern and is well structured and well written. It also has a lot of unit tests and it is still actively maintained (bug fixing, minor features adding). Therefore I want to preserve the original structure and code style as much as possible. The new feature I am going to add is a conceptual one, so I have to make my changes all over the code. In order to minimize changes I decided not to extend existing classes but to use containment: class ExistingClass { // .... existing code // my code adding new functionality private ExistingClassExtension extension = new ExistingClassExtension(); public ExistingClassExtension getExtension() {return extension;} } ... // somewhere in code ExistingClass instance = new ExistingClass(); ... // when I need a new functionality instance.getExtension().newMethod1(); All functionality that I am adding is inside a new ExistingClassExtension class. Actually I am adding only these 2 lines to each class that needs to be extended. By doing so I also do not need to instantiate new, extended classes all over the code and I may use existing tests to make sure there is no regression. However my colleagues argue that in this situation doing so isn't a proper OOP approach, and I need to inherit from ExistingClass in order to add a new functionality. What do you think? I am aware of numerous inheritance/containment questions here, but I think my question is different.

  • How to start and maintain an after-work project

    - by Sam
    I work as a full time developer. My workplace, however, is very limiting in the technologies and programming languages I can use. All of the work is done in C++. It is clear that C++ is rapidly losing (or maybe already lost) its leading position. (please don't flame me, I have years and years of C++ experience, and I love this language, I am merely stating a fact). I have a few ideas for java/android projects as well as a project I would like to implement in C#. I see this as a way for me to stay current with the job market's trends and I hope that it will help me find my next job in a more up to date area. So here's the problem, my normal workday is 10-11 hours, after finishing with the kids and house chores I get about 1-2.5 hours before I am too tired to think much less code. at that point I am going to bed frustrated, disappointed with myself for not being able to stick with my plans, and then I wake up the next morning to do it all again. I have a few hours more during the weekends but clearly I would need to do something different if I want to reach any of my goals. Is there any way for me to make better use of the time I have? Did any of you guys have a similar problem, and had succefully resolved it?

  • Which architecture should I choose for this project?

    - by Jichao
    I have a project. The server which based on a phone PCI-board is responsible for received phone calls from the customer and then redirect the phone calls to the operators. I have decided to code the server using c++ programming language and qt framework because the PCI-board SDK's interface is c/c++ originated and for the sake of portability. The server need to send the information of the the customer to the operator while ringing the operator and the ui interface of the operator client should be browser-based. Now the key problem is how could the server notify the operator that there is a phone call for he/she. One architecture I have considered is like this, The operator browser client use ajax pooling the web server to check whether there is call to the client; the web server pooling the database server to check whether there is call; the desktop server(c++) wait for the phone calls and set the information in the database. The other operations such as hang up the phone call from the client, retransfer the phone call to the other operator also use this architecture. Then, is there any way other than pooling the server(js code setInterval('getDail', 1000)) to decide whether there is a call to the operator? Is this architecture feasible or should I use some terrific techniques that I do know such as web services,xml-rpc, soap???

  • Adding files and folders to a Root Folder (inode/directory)

    - by xBaldwin
    Ok so I'm fairly new to Ubuntu and wasn't even the one who put it one this computer(my friend did while I was storing it at his house because I was in the middle of transitioning between houses), but It's on here so I need to learn what I can so I can use it more effectively. My question at the moment is "Would it be safe to add files/folders to a folder (inode/directory) that requires Root access?" I continue to be informed by the system that the directory I am using is running low on space which I found odd seeing how I should have a lot more room on this computer. That's when I started looking at the directories and found that there are two with a bunch of un-used space on them. One says it has 46.9 GB of free space and the other has 24.9 GB of free space. Seems like a complete waste to not use that space and yet they both say they require Root access to add to them. I know that Root folders and files are normally all system folders and files. I also know that changing or deleting them can mess up the computer which right now I cant afford to do. I just don't know if it would mess anything up to add something to those folders. Thank you in advance to anyone who takes the time to reply and try to teach me about how all that works. I really do appreciate it and will do the same if by some crazy (completely unlikely) reason I have an answer to your question. :-)`

  • Browser automatically refreshes and Home folder window opens

    - by Vikash
    I am facing a very strange problem. Out of the blue, my browser starts refreshing itself infinitely. My first guess was firefox is messing up. I installed chrome. But, it happens in chrome as well. Other than that, sometimes my home folder automatically opens and keep opening itself infinitely. My next guess was Mouse is faulty. Replace the mouse - but same things. This happens even if I remove my keyboard. What can be the reason? This started happening after I installed Ubuntu 10.10 few days back. Earlier on windows, everything was working fine. So, I am a bit skeptical to assume that this is a hardware fault. How to fix this problem?

  • Project Jigsaw: On the next train

    - by Mark Reinhold
    I recently proposed to defer Project Jigsaw from Java 8 to Java 9. Feedback on the proposal was about evenly divided as to whether Java 8 should be delayed for Jigsaw, Jigsaw should be deferred to Java 9, or some other, usually less-realistic, option should be taken. The ultimate decision rested, of course, with the Java SE 8 (JSR 337) Expert Group. After due consideration, a strong majority of the EG agreed to my proposal. In light of this decision we can still make progress in Java 8 toward the convergence of the higher-end Java ME Platforms with Java SE. I previously suggested that we consider defining a small number of Profiles which would allow compact configurations of the SE Platform to be built and deployed. JEP 161 lays out a specific initial proposal for such Profiles. There is also much useful work to be done in Java 8 toward the fully-modular platform in Java 9. Alan Bateman has submitted JEP 162, which proposes some changes in Java 8 to smooth the eventual transition to modules, to provide new tools to help developers prepare for modularity, and to deprecate and then, in Java 9, actually remove certain API elements that are a significant impediment to modularization. Thanks to everyone who responded to the proposal with comments and questions. As I wrote initially, deferring Jigsaw to a Java 9 release in 2015 is by no means a pleasant decision. It does, however, still appear to be the best available option, and it is now the plan of record.

  • Importing an existing project into Git

    - by Andy
    Background During the course of developing our site (ASP.NET), we discovered that our existing source control (SourceGear Vault) wasn't working for us. So, we decided to migrate to Git. The translation has been less than smooth though. Our site is broken up into three environments DEV, QA, and PROD. For tho most part, DEV and the source control repo have been in sync with each other. There is one branch in the repo, if a page was going to be moved up to QA then the file was moved manually, same thing with stuff that was ready for PROD. So, our current QA and PROD environments do not correspond to any particular commit in the master branch. Clarification: The QA and PROD branches are not currently, nor have they ever been in source control. The Question How do I move QA and PROD into Git? Should I forget about the history we've maintained up to this point and start over with a new repo? I could start with everything on PROD, then make a branch and pull in everything from QA, and then make another branch off of that with DEV. That way not only will the branches reflect the differences in the environments, they'll be in the right order chronologically with the newest commits in the DEV branch. What I've tried so far I thought about creating a QA branch off of the current master and using robocopy to make the working folder look like the current QA environment. This doesn't work because the new commit from QA will remove new files from DEV and that will remove them when we merge up, I suspect there will be similar problems if I started QA at an earlier (though not exact) commit from DEV.

  • JiglibX addition to existing project questions

    - by SomeXnaChump
    Got a very simple existing project, that basically contains a lot of cubes. Now I am wanting to add a physics system to it and JiglibX seemed like the simplest one with some tutorials out there. My main problem is that the physics don't seem to be working how I imagined, I expected my tower of cubes to come crashing down, but they dont seem to do anything. I think my problem is that my cubes do not inherit DrawableGameComponent, they are managed by a world object that will update and render them. So they are at no point put into the games component list. I am not sure if this means that JiglibX will not be able to interact with them as in all the tutorials there are no explicit calls to add the Body objects to the physics system, so I can only presume that they are using a static/singleton under the hood which automatically hooks in all things, or they use the game objects component list somehow. I also noticed that in alot of the tutorials they use the following when setting up the physics system: float timeStep = (float)gameTime.ElapsedGameTime.Ticks / TimeSpan.TicksPerSecond; PhysicsSystem.CurrentPhysicsSystem.Integrate(timeStep); Would it not be better to keep a local instance of the created PhysicsSystem object and just call myPhysicsSystem.Integrate(timeStep)?

  • Deleted info in Boot folder

    - by user207984
    First off, I'm using Zorin 7 OS. So my Boot folder was too full to install any new updates, I used a tutorial I found somewhere on here to remove the unneeded linux-image files, and must of also deleted the latest one as well. Now when I attempt to boot I get error: no such partition. grub rescue> I used my MultiSystem USB to install (on a separate partition) a different Linux OS (Kali) and no longer get that error, however, it will ONLY give me the option to boot Kali Linux. Here's the biggest new problem though, I used the built in option of hard drive encryption for Zorin 7 when I initially installed it, so now when I attempt to explore it (to get all my saved data which is REALLY important to me), it asks me for password for encryption. However, the password says it in not recognized, and I know it's right, I had to type it in every single day. So I either need a way to restore my Zorin 7 boot files or GRUB or whatever, so I can boot it up... or I need to know how to fix my encryption problem to save all my info.

  • Windows Server or Linux for final project

    - by user1433490
    A few weeks ago I came up with an idea to develop a mobile app which will direct students in my university to the nearest printer availiable. The whole thing is part of my final project. The Android based app will need to perform the following tasks: The user's location in the campus is sent to the server. Assume this part works just fine. The server sends an SNMP request to the printers in the user's vicinity. I'll probably use PHP or Python for that part. The data requested by SNMP is processed and sent back to the client My question concerns the server. The university's IT manager offered me a designated server for development, which sounds great. Now I need to choose which OS I want installed on the server - Windows server or Linux (don't know which versions). I don't have any server programming/operating experince, but generally speaking I feel more comfortable in Windows enviroment (just because that has always been my OS). I don't have much time for learning a new OS, but when does it make sense generally to host or develop server side applications on a Windows environment versus a Linux environment?

  • How can I avoid team burnout?

    - by Shawn Dalma
    I work for a small web company that deals with a lot of projects, a few at any given time are development heavy for us (400-1500 hours or more) and I've been noticing developers get extremely burnt out on a project after 150 hours or so. I've been toying around with the idea of working some form of rotation/rest so when someone reaches the threshold, they at least get some time off of working on that project. Is there an industry standard approach?

  • Encouraging software engineers to track time

    - by M. Dudley
    How can I encourage my coworkers to track the time they spend resolving issues and implementing features? We have software to do this, but they just don't enter the numbers. I want the team to get better at providing project estimates by comparing our past estimates to actual time spent. I suspect that my coworkers don't see the personal benefit, since they're not often involved in project scheduling.

  • Design pattern for an ASP.NET project using Entity Framework

    - by MPelletier
    I'm building a website in ASP.NET (Web Forms) on top of an engine with business rules (which basically resides in a separate DLL), connected to a database mapped with Entity Framework (in a 3rd, separate project). I designed the Engine first, which has an Entity Framework context, and then went on to work on the website, which presents various reports. I believe I made a terrible design mistake in that the website has its own context (which sounded normal at first). I present this mockup of the engine and a report page's code behind: Engine (in separate DLL): public Engine { DatabaseEntities _engineContext; public Engine() { // Connection string and procedure managed in DB layer _engineContext = DatabaseEntities.Connect(); } public ChangeSomeEntity(SomeEntity someEntity, int newValue) { //Suppose there's some validation too, non trivial stuff SomeEntity.Value = newValue; _engineContext.SaveChanges(); } } And report: public partial class MyReport : Page { Engine _engine; DatabaseEntities _webpageContext; public MyReport() { _engine = new Engine(); _databaseContext = DatabaseEntities.Connect(); } public void ChangeSomeEntityButton_Clicked(object sender, EventArgs e) { SomeEntity someEntity; //Wrong way: //Get the entity from the webpage context someEntity = _webpageContext.SomeEntities.Single(s => s.Id == SomeEntityId); //Send the entity from _webpageContext to the engine _engine.ChangeSomeEntity(someEntity, SomeEntityNewValue); // <- oops, conflict of context //Right(?) way: //Get the entity from the engine context someEntity = _engine.GetSomeEntity(SomeEntityId); //undefined above //Send the entity from the engine's context to the engine _engine.ChangeSomeEntity(someEntity, SomeEntityNewValue); // <- oops, conflict of context } } Because the webpage has its own context, giving the Engine an entity from a different context will cause an error. I happen to know not to do that, to only give the Engine entities from its own context. But this is a very error-prone design. I see the error of my ways now. I just don't know the right path. I'm considering: Creating the connection in the Engine and passing it off to the webpage. Always instantiate an Engine, make its context accessible from a property, sharing it. Possible problems: other conflicts? Slow? Concurrency issues if I want to expand to AJAX? Creating the connection from the webpage and passing it off to the Engine (I believe that's dependency injection?) Only talking through ID's. Creates redundancy, not always practical, sounds archaic. But at the same time, I already recuperate stuff from the page as ID's that I need to fetch anyways. What would be best compromise here for safety, ease-of-use and understanding, stability, and speed?

  • introducing pointers to a large software project

    - by stefan
    I have a fairly large software project written in c++. In there, there is a class foo which represents a structure (by which i don't mean the programmers struct) in which foo-objects can be part of a foo-object. Here's class foo in simplest form: class Foo { private: std::vector<unsigned int> indices; public: void addFooIndex(unsigned int); unsigned int getFooIndex(unsigned int); }; Every foo-object is currently stored in an object of class bar. class Bar { private: std::vector<Foo> foos; public: void addFoo(Foo); std::vector<Foo> getFoos(); } So if a foo-object should represent a structure with a "inner" foo-object, I currently do Foo foo; Foo innerFoo; foo.addFooIndex(bar.getFoos().size() - 1); bar.addFoo(innerFoo); And to get it, I obviously use: Foo foo; for ( unsigned int i = 0; i < foo.getFooIndices().size(); ++i ) { Foo inner_foo; assert( foo.getFooIndices().at(i) < bar.getFoos().size() ); inner_foo = bar.getFoos().at(foo.getFooIndices().at(i)); } So this is not a problem. It just works. But it's not the most elegant solution. I now want to make the inner foos to be "more connected" with the foo-object. It would be obviously to change class foo to: class Foo { private: std::vector<Foo*> foo_pointers; public: void addFooPointer(Foo*); std::vector<Foo*> getFooPointers(); }; So now, for my question: How to gently change this basic class without messing up the whole code? Is there a "clean way"?
