• MS in Computer Science after BE in electronics

  - by Abhinav

  I am doing my 3rd year Bachelors in Electronics and Electrical Communication but from the first year I have been interested in Computer Science. But at that time it was just my hobby. But in second year when I joined robotics my love for computer science rose. I with my team came in top three in 2 National Competition (Technical fests of different IITs) where we used Image Processing, Hardware interfacing etc. But then I realised that Computer Science is not just about coding. I took many lectures from online free schools like Udacity, Coursera in subjects related to Artificial Intelligence, Building a Search Engine, Design and Analysis of Algorithm, Programming a Robotic Car, Programming Languages, Machine Learning, Software Engineering as a Service, WebApps Engineering, Compilers, Applied Crypotography etc. I also did some courses in Core and Advanced Java in my second year from training institute. I will also be taking course in Statistics, Databases, Discrete Mathematics from 25th June. Now I realized how vast is the field of Computer Science and how efficient you become on deciding algorithms and classifying problems into different subfields which have been thoroughly researched so you don't always do brute force thing or naive programming. Now this field has become kind of passion for me. Adding to the fact I am also doing my 6 months internship in software field in Texas Instruments where I am working on Automation and Algorithms. I also have some 5-6 good college level projects in Softwares and Robotics. I also like Electronics but only some fields like Operating System(this subject was there in Electronics also), Micro Processor, Digital, Computer Architecture, DSPs etc. I really want to pursue MS in some field of Computer Science. I am giving GRE in October/November. Till now I have good CG of around 9.4/10 and my 1 year in college is still left. Do I have any chance that some good University in US will consider me for MS in field related to computer science or Robotics. Also Can you suggest somethings that I can do during this 1 year to increase my chances for MS or should I apply for EECS(Electrical Engineering and Computer Science) and then I can shift more towards Computer Science as my major option. My main aim is to do Phd after Ms in CS if I am able to do that somehow. I know that I have to put much extra effort to understand things in MS than CS undergraduates but I will do that with my full dedication, also when I communicate with my college CS students or during my internship period I didn't feel that I am missing very much stuff that they know and was very comfortable during my internship with software employees.

• Code Coverage for Maven Integrated in NetBeans IDE 7.2

  - by Geertjan

  In NetBeans IDE 7.2, JaCoCo is supported natively, i.e., out of the box, as a code coverage engine for Maven projects, since Cobertura does not work with JDK 7 language constructs. (Although, note that Cobertura is supported as well in NetBeans IDE 7.2.) It isn't part of NetBeans IDE 7.2 Beta, so don't even try there; you need some development build from after that. I downloaded the latest development build today. To enable JaCoCo features in NetBeans IDE, you need do no different to what you'd do when enabling JaCoCo in Maven itself, which is rather wonderful. In both cases, all you need to do is add this to the "plugins" section of your POM: <plugin> <groupId>org.jacoco</groupId> <artifactId>jacoco-maven-plugin</artifactId> <version>0.5.7.201204190339</version> <executions> <execution> <goals> <goal>prepare-agent</goal> </goals> </execution> <execution> <id>report</id> <phase>prepare-package</phase> <goals> <goal>report</goal> </goals> </execution> </executions> </plugin> Now you're done and ready to examine the code coverage of your tests, whether they are JUnit or TestNG. At this point, i.e., for no other reason than that you added the above snippet into your POM, you will have a new Code Coverage menu when you right-click on the project node: If you click Show Report above, the Code Coverage Report window opens. Here, once you've run your tests, you can actually see how many classes have been covered by your tests, which is pretty useful since 100% tests passing doesn't mean much when you've only tested one class, as you can see very graphically below: Then, when you click the bars in the Code Coverage Report window, the class under test is shown, with the methods for which tests exist highlighted in green and those that haven't been covered in red: (Note: Of course, striving for 100% code coverage is a bit nonsensical. For example, writing tests for your getters and setters may not be the most useful way to spend one's time. But being able to measure, and visualize, code coverage is certainly useful regardless of the percentage you're striving to achieve.) Best of all about all this is that everything you see above is available out of the box in NetBeans IDE 7.2. Take a look at what else NetBeans IDE 7.2 brings for the first time to the world of Maven: http://wiki.netbeans.org/NewAndNoteworthyNB72#Maven

• What to use C++ for?

  - by futlib

  I really love C++. However, I'm struggling to find good uses for it lately. It is still the language to use if you're building huge systems with huge performance requirements. Like backend/infrastructure code at Google and Facebook, or high-end games. But I don't get to do stuff like that. It's also a good choice for code that runs close to the hardware. I'd like to do more low-level stuff, but it isn't part of my job, and I can't think of useful private projects that would involve that. Traditionally, C++ was also a good choice for rich client applications, but those are mostly written in C# and Obj-C lately - and aren't really that important anymore, with everything being a web app. Or a mobile app, which are mostly written in Obj-C and Java. And of course, web-based desktop and mobile apps are quite prominent, too. At my job, I work mostly on web applications, using Java, JavaScript and Groovy. Java is a good/popular choice for non-Google-scale backends, Groovy (or Python, or Ruby or Node.js) is pretty good for the server-side of web apps and JavaScript is the only real choice for the client-side. Even the little games I'm writing in my spare time are lately mostly written in JavaScript, so they can run in the browser. So what would you suggest I could use C++ for? I'm aware that this question is very similar. However, I don't want to learn C++, I was a professional C++ programmer for years. I want to keep doing it and find good new use cases for it. I know that I can use C++ for web apps/games. I could even compile C++ to JavaScript with Emscripten. However, it doesn't seem like a good idea. I'm looking for something C++ is really good at to stay competent in the language. If your answer is: Just give up and forget C++, you'll probably never need it again, so be it.

• Legality of similar games

  - by Jamie Taylor

  This is my first question on GD.SE, and I hope it's in the right place. A little background: I'm an amateur (read: not explicitly employed to develop games, but am employed as a software developer) game developer and took a ComSci with Games Development degree. My Question: What is the legal situation/standpoint of creating a copycat title? I know that there are only N number of ways of solving a problem, and N number of ways to design a piece of software. Say that an independent developer designed a copycat game (a Tetris clone in this example) for instance, and decided to use that game to generate income for themselves as well as interest for their other products. Say the developer adds a disclaimer into the software along the lines of "based on , originally released c. by ." Are there any legal problems/grey areas with the developer in this example releasing this game, commercially? Would they run into legal problems? Should the developer in this example expect cease and desist orders or law suit claims from original publishers? Have original publishers been known to, effectively, kill independent projects because they are a little too close to older titles? I know that there was, at least, one attempt by a group of independent developers to remake Sonic the Hedgehog 2 and Sega shut them down. I also know of Sega shutting down development of the independent Streets of Rage Remake. I know that "but it's an old game, your honour," isn't a great legal standpoint when it comes to defending yourself. But, could an independent developer have a law suit filed against them for re-implementing an older title in a new way? I know that there are a lot of copycat versions of the older titles like Tetris available on app stores (and similar services), and that it would be very difficult for a major publisher to shut them all down. Regardless of this, is making a Tetris (or other game) copycat/clone illegal? We were taught lots of different things at University, but we never covered copyright law. I'm presuming that their thought behind it was "IF these students get jobs in games development, they wont need to know anything about the legal side of it, because their employers will have legal departments... presumably" tl;dr Is it illegal to create a clone or copycat of an old title, and make money from it?

• The Birth of SSAS Compare

  - by Red Gate Software BI Tools Team

  Noemi Moreno, Red Gate Business Intelligence Specialist Software vendors – even Microsoft – tend to forget about the needs of business intelligence developers. We are a rare and rather invisible species. For example, BIDS remained in VS 2008 until SQL Server 2012. It took until this release before we got something as simple as an “undo” function. Before I joined Red Gate as a BI specialist, I worked on SQL Development. I’ll never forget the time I discovered Red Gate’s SQL Compare tool and how it reduced the task of preparing a database release from a couple of days to ten minutes. When I moved to SSAS, MDX and cubes, I became frustrated with the deployment process because I couldn’t find a tool that made Cube releases as easy as they are with SQL Compare. This became my quest. I pitched the idea to a few people in Red Gate’s regular Down Tools Week, when everyone puts down their day-to-day tasks and works on their own projects. My task was to reason with a roomful of cynical developers, hardened to the blandishments of project managers, for help to develop a tool that would compare two different SSAS databases and create the script to process only the objects that needed processing, thereby reducing release time to only a few minutes. I walked to the podium and gave them the full story of the distressed BI specialists, doomed to spend tedious hours preparing deployment scripts. A few developers recovered from their torpor to cast a languid eye at my presentation. It wasn’t enough. In a sudden impulse, I blurted out a promise to perform a flamenco dance for just the team if the tool was able to successfully compare two SSAS databases and generate a script by the end of the week. I was lucky enough that some of them believed me and jumped in: David Pond (Dev), Matt Burton (Dev), Tilman Bregler (Dev), Shobana Sekar (Test), Ruchija Raj (Test), Nick Sutherland (Product Manager) and Irma Tanovic (BI). They didn’t know that Irma and I would be away on a conference in Amsterdam and would leave them without our support. But to my surprise, they had a working tool by the time we came back – basic, and with a few bugs, but a working tool nonetheless! Seeing it compare a very basic SSAS database, detect the changes and generate the scripts was amazing! Something that normally takes half a day was done in under a minute. Since then, a few months have passed and a BI Tools team has been created at Red Gate to work full time on BI tools for BI developers, starting with SSAS Compare. How cool is that? So download the free beta and give us your feedback. And the flamenco? I still need to deliver that. Tilman reminds me every day! I need to get the full flamenco costume.

• ArchBeat Link-o-Rama for 2012-08-29

  - by Bob Rhubart

  ORCLville: OOW 2012 - Crystal BallOracle ACE Director Floyd Teter cooks up some tongue-in-cheek predictions for news and announcements that might come out of Oracle OpenWorld 2012. What's your prediction? Oracle Optimized Solutions at Oracle OpenWorld 2012 | Oracle Hardware Hardware matters, too! The people behind the Oracle Hardware blog have put together a list of Oracle Openworld 2012 sessions focused Oracle Optimized Solutions, "designed, pre-tested, tuned and fully documented architectures for optimal performance and availability." Just plug the session ID numbers into Schedule Builder and you're good to go. AIX Checklist for stable OBIEE deployment | Dick Dunbar "OBIEE is a complicated system with many moving parts and connection points," according to Oracle Business Inteligence escalation engineer Dick Dunbar. "The purpose of this article is to provide a checklist to discuss OBIEE deployment with your systems administrators." Demo for OPN: Coherence Management with EM Cloud Control 12c Oracle Partner Network members can check out a new Coherence Management demo that showcases some of the key capabilities of Management Pack for Oracle Coherence and JVM Diagnostics. "The demo flow showcases the key enhancements made in Enterprise Manager 12c release which includes new customizable performance summary, cache data management and configuration management," according to the WebLogic Partner Community EMEA blog. The Pragmatic Architect: To Boldly Go Where No One Has Gone Before | Frank Buschmann "Many architects have technical knowledge that's both impressive and sound, which is indeed an inevitable basis for design success," says Frank Buschmann. "Yet, a lot of software projects fail or suffer due to severe challenges in their architecture. The key to mastery is how architects approach design, what they value, and where they focus their attention and work." As retail dies, whom will be the winners? | Peter Evans-Greenwood "The problem for many retailers is that how consumers shop has changed but the the retailers haven't adapted, " says Peter Evans-Greenwood. "Their sole virtue was to be the last step in a supply chain delivering somebody else's products to the consumer. However, being the last step in the supply chain is no longer a virtue when consumers skip across channels and can reach around the globe, no longer dependant on or limited to what they can find locally." Thought for the Day "Brains require stimulation. If you're locked into a pattern of work, work, and more work, your brain soon habituates - the same way that it lets you stop hearing a clock ticking. So, if you want to be more effective at work, you must, paradoxically, be less single-minded in your devotion to work. Anything you do—anything—that stimulates new segments of your brain will make you a more effective programmer or analyst. I promise, with a money-back guarantee." — Gerald M.

• Misadventures at Radio Shack

  - by Chris Williams

  While I'm waiting for my Arduino kits to show up, I started reading the Getting Started With Arduino book from O'Reilly (review coming later) and I'm about 40 pages in when I get to a parts list for one of the first projects. Looks pretty straightforward, and even has Radio Shack part numbers next to almost everything. So on my lunch today, I decided to run out to "The Shack" (seriously, that's their rebranding?) to pick up some basics, like a couple resistors, a breadboard, a momentary switch and a pack of pre-cut jumper wires. I found the resistors without any difficulty, and while they didn't have the exact switch I wanted, it was easy enough to find one that would do. That's where my good luck abruptly ended. I was surprised that I couldn't find a breadboard or any jumper wires, so while I was looking around, a guy came up and asked me if I needed some help. I told him I did, explained what I needed and even gave him the Radio Shack part number for the pack of jumper wires. After a couple minutes he says he can't find anything in the system, which was unfortunate but not the end of the world.  So then I asked him about the breadboard, and he pointed me to some blank circuitboards (which are not the same thing) and I said (nicely) that those weren't breadboards and attempted to explain (again) what I needed, at which point he says to me "I don't even know what the hell you're looking for!" I stood there for a moment and tried to process his words. About that time, another salesperson came up and asked what I was trying to find. I told her I needed a breadboard, and she pointed to the blank circuit boards and said "they're right in front of you..." After seeing the look on my face, she thought for a minute and said... "OH! you mean those white things. We don't have those anymore." I thanked her, set everything down on the counter and left. (I wasn't going to buy only half the stuff I needed.. and I was pretty sure I was never going to be buying ANYTHING at that particular location ever again.) Guess I'll be ordering more stuff online at this point. It's a shame really, because I used to LOVE going to Radio Shack as a kid, and looking through all the cool electronics components and stuff, even if I didnt understand what most of them were at the time. Seems like the only thing they carry in any quantity/variety now is cell phones and random stereo connectors.

• How to handle this unfortunately non hypothetical situation with end-users?

  - by User Smith

  I work in a medium sized company but with a very small IT force. Last year (2011), I wrote an application that is very popular with a large group of end-users. We hit a deadline at the end of last year and some functionality (I will call funcA from now on) was not added into the application that was wanted at the very end. So, this application has been running in live/production since the end of 2011, I might add without issue. Yesterday, a whole group of end-users started complaining that funcA that was never in the application is no longer working. Our priority at this company is that if an application is broken it must be fixed first prior to prioritized projects. I have compared code and queries and there is no difference since 2011, which is proofA. I then was able to get one of the end-users to admit that it never worked proofB, but since then that end-user has went back and said that it was working previously......I believe the horde of end-users has assimilated her. I have also reviewed my notes for this project which has requirements and daily updates regarding the project which specifically states, "funcA not achieved due to time constraints", proofC. I have spoken with many of them and I can see where they could be confused as they are very far from a programming background, but I also know they are intelligent enough to act in a group in order to bypass project prioritization orders in order to get functionality that they want to make their job easier. The worst part is is that now group think is setting in and my boss and the head of IT is actually starting to believe them, even though there is no code or query changes. As far as reviewing the state of the logic it is very cut and dry to the point of if 1 = 1, funcA will not work. So, this is the end of the description of my scenario, but I am trying not to get severally dinged on my performance metrics due to this which would essentially have me moved to fixing a production problem that doesn't exist that will probably take over 1 month. I am looking for direct answers to this question. This question is not for rants, polling, or discussions as this is not the format for StackExchange. Please don't downvote me too terribly it is pretty common on this specific site of stack, I am looking for honest answers to this situation and I couldn't find a forum more appropriate.

• .Net Application & Database Modularity/Reuse

  - by Martaver

  I'm looking for some guidance on how to architect an app with regards to modularity, separation of concerns and re-usability. I'm working on an application (ASP.Net, C#) that has distinctly generic chunks of functionality, that I'd love to be able to lift out, all layers, into re-usable components. This means the module handles the database schema, data access, API, everything so that the next time I want to use it I can just register the module and hook into it. Developing modules of re-usable functionality is a no-brainer, but what is really confusing me is what to do when it comes to handling a core re-usable database schema that serves the module's functionality. In an ideal world, I would register a module and it would ensure that the associated database schema exists in the DB. I would code on the assumption that the tables exist, calling the module's functionality through the DLL, agnostic of the database layer. Kind of like Enterprise Library's Caching/Logging Application Block, which can create a DB schema in the target DB to use as a data store. My Questions is: What do you think is the best way to achieve this, firstly, in terms design architecture, and secondly solution structure. What patterns/frameworks do you know that exist & support this kind of thing? My thoughts so far: I mostly use Entity Framework and SQL Server DB Projects. I thought about a 'black box' approach to modules of functionality. I could use use a code-first approach in EF4, and use the ObjectContext to create a database when the module is initialized. However this means that all of the entities that my module encapsulates would be disconnected from the rest of the application because they belonged to an abstracted ObjectContext. Further - Creating appropriate indexes and references between domain entities and the module's entities would be impossible to do practically. I've thought of adopting Enterprise Library and creating my own Application Blocks. I'm not sure how this would play nice with Entity Framework (if at all) though. I like the idea of building on proven patterns & practices to encapsulate established, reusable functionality. I thought of abandoning Entity Framework for the Module, and just creating a separate DB schema for the module with its own set of stored procedures & ADO.Net. Then deploying the script at run-time if interrogation shows that it doesn't exist. But once again, for application developing outside of the application, I would want to use Entity Framework and I would have to use the module separately, disconnected from the domain ObjectContext. Has anyone had experience developing these sorts of full-stack modules? What advice can you offer? Am I biting off more than I can chew?

• iTorque for a simple arcade game

  - by Herfus

  I have a basic understanding of programming, but I am no programmer. I've had a couple of a semesters with java programming, so we're talking pretty basic here. I have some scripting experience with game editors where I've created a few (simple) encounters, boss AI, abilities, events and so on. I've mostly done level design with UDK, Source and several other toolsets for a few years now, but I'd like to divert some of the focus to iphone-development. I've participated in a few development projects (source, udk, daot) where I've had a variety of roles (yet never beyond simple scripting). I have just finished prototyping an Iphone game (using game maker) and begun a bit more precise planning on what I'll have to do for the real version. The game is fairly simple, perhaps the best comparison in scope and complexity would be Doodlejump for iPhone. The reason I created the prototype was not just to answer a few questions about the gameplay, but to get some insight into what kind of problems I might face when trying to develop the real thing. I've been looking for engines that I can use for this. iTorque looks, so far, like the best option with a scripting language and WYSIWYG-editor. However the price is fairly steep and I'd like to prepare myself as much as possible before jumping into this, which is why I'm going to ask a few questions here. What kind of difficulties do you think I might run into, considering what you've read so far? Not just with torque, but development in general. I'm making this question mostly to have someone to reality check me. I usually achieve to do what I'm trying to do with scripting, but something tells me there's a very big difference between scripting an AI or an event and creating game logic. Will it be too much of a leap? Just how simple is it to use the Torque scripting language? Obviously I don't expect to be prepared, I expect it to be a learning process. However, I'd still like to be at least a bit confident on the time I'll have to dedicate to this first.

• Tell me a Story

  - by Geoff N. Hiten

  I recently had a friend ask me to review his resume.  He is a very experienced DBA with excellent skills.  If I had an opening I would have hired him myself.  But not because of the resume.  I know his skill set and skill levels, but there is no way his standard resume can convey that.  A bare bones list of job titles and skills does not set you apart from your competition, nor does it convey whether you have junior or senior level skills and experience.  The solution is to not use the standard format. Tell me a story.  I want to know what you were responsible for.  Describe a tough project and how you saved time/money/personnel on that project.  Link your work activity to business value.  Drop some technical bits in there since we do work in a technical field, but show me what you can do to add value to my business well above what I would pay you.  That will get my attention. The resume exists for one primary and one secondary reason.  The primary reason is to get the interview.  A Resume won’t get you a job, so don’t expect it to.  The secondary reason is to give you and the interviewer a starting point for conversations.  If I can say “Tell me more about when….” and reference an item from your resume, then that is great for both of us.  Of course, you better be able to tell me more, both from the technical and the business side, at least if I am hiring a senior or higher level position.  As for the junior DBAs, go ahead and tell your story too.  Don’t worry about how simple or basic your projects or solutions seem.  It is how you solved the problem and what you learned that I am looking for.  If you learn rapidly and think like a DBA, I can work with that, regardless of you current skill level.

• Headaches using distributed version control for traditional teams?

  - by J Cooper

  Though I use and like DVCS for my personal projects, and can totally see how it makes managing contributions to your project from others easier (e.g. your typical Github scenario), it seems like for a "traditional" team there could be some problems over the centralized approach employed by solutions like TFS, Perforce, etc. (By "traditional" I mean a team of developers in an office working on one project that no one person "owns", with potentially everyone touching the same code.) A couple of these problems I've foreseen on my own, but please chime in with other considerations. In a traditional system, when you try to check your change in to the server, if someone else has previously checked in a conflicting change then you are forced to merge before you can check yours in. In the DVCS model, each developer checks in their changes locally and at some point pushes to some other repo. That repo then has a branch of that file that 2 people changed. It seems that now someone must be put in charge of dealing with that situation. A designated person on the team might not have sufficient knowledge of the entire codebase to be able to handle merging all conflicts. So now an extra step has been added where someone has to approach one of those developers, tell him to pull and do the merge and then push again (or you have to build an infrastructure that automates that task). Furthermore, since DVCS tends to make working locally so convenient, it is probable that developers could accumulate a few changes in their local repos before pushing, making such conflicts more common and more complicated. Obviously if everyone on the team only works on different areas of the code, this isn't an issue. But I'm curious about the case where everyone is working on the same code. It seems like the centralized model forces conflicts to be dealt with quickly and frequently, minimizing the need to do large, painful merges or have anyone "police" the main repo. So for those of you who do use a DVCS with your team in your office, how do you handle such cases? Do you find your daily (or more likely, weekly) workflow affected negatively? Are there any other considerations I should be aware of before recommending a DVCS at my workplace?

• The only metric with any value

What's the velocity? How big is a story point?  How many story points is that team producing per man hour?   People are sadly missing the whole point.  Take your measurements up a level or two.  When you get down to it, the only metric that makes any difference, is ROI.   The problem is that often times, the developers work in a dark hole, far removed from the realities of how exactly they get paid.  A bigger problem is that mid-level managers tend to be further removed from the realities of ROI.  A lot of times mid-level managers get tasked with tracking their teams "productivity" using things like, "lines of code", or "completeness of the productivity reports."   Monetize your projects and then track your velocity against business value (real dollars).    When your development teams can say, "Last year, our team cost the business 2 million dollars and we know that because of our efforts, the company saved 2 million dollars in waste and increased revenues by another 4 million dollars." At that point you have just moved your development team from a cost center, to a profit center.  You might have to give them a raise, but they have demonstrated that they have earned it.

• Design pattern to handle queries using multiple models

  - by coderkane

  I am presented with a dilemma while trying to re-designing the class structure for my PHP/MySQL application to make it more elegant and conform it to the SOLID principle. The problem goes like this: Let as assume, there is an abstract class called person which has certain properties to define a generic person, such as name, age, date of birth etc. There are two classes, student, and teacher, that implements this abstract class. They add their own unique properties to it. I have designed all the three classes to include all the operational logic (details of which are not relevant in context of the question). Now, I need to create views/reports/data grids which contain details from multiple classes, for example, say, a list of all students doing projects in Chemistry mentored by a teacher whose name is the parameter to the query. This is just one example of a view, there are many different views in the application, which uses data from 3-4 tables, and each of them have multiple input parameters to generate them. Considering this particular example, I have written the relevant query using JOIN and the results are as expected and proper, now here is the dilemma: Keeping in mind the single responsibility principle, where should I keep this query? It does not belong to either Student class, or Teacher class or any other classes currently present. a) Should I create a new class, say dataView class, and design it as a MVC pattern and keep the query there? What about the other views? how do they fit in this architecture? b) Should I not keep the query in code at all, and make it DB View ? c) Am I completely wrong in the approach? If so what is the right approach? My considerations are as follows: a) should be easy to add new views later on if requirement comes, without having to copy-paste-modify code b) would like to make it as loosely coupled as possible so that if minor db structure changes happen, it does not break I did google searches on report design and OOP report generators, but all the result seem to focus on the visual design of the report rather than fetching the data. I have already taken care of the visual aspect of the report using MVC with html templates. I am sure this is a very fundamental problem with known solution, but I am somehow not able to find it (maybe searching with wrong keyword). Edit1: Modified the title to make it more relevant Edit2: The accepted answer got me thinking in the right direction and identify my design flaws, which eventually led me to find this question and the solution in Stack Overflow which gave me the detailed answer to clear the confusion.

• How do I take responsibility for my code when colleague makes unnecessary improvements without notice?

  - by Jesslyn

  One of my teammates is a jack of all trades in our IT shop and I respect his insight. However, sometimes he reviews my code (he's second in command to our team leader, so that's expected) without a heads up. So sometimes he reviews my changes before they complete the end goal and makes changes right away... and has even broken my work once. Other times, he has made unnecessary improvements to some of my code that is 3+ months old. This annoys me for a few reasons: I am not always given a chance to fix my mistakes He has not taken the time to ask me what I was trying to accomplish when he is confused, which could affect his testing or changes I don't always think his code is readable Deadlines are not an issue and his current workload doesn't require any work in my projects other than reviewing my code changes. Anyways, I have told him in the past to please keep me posted if he sees something in my work that he wants to change so that I could take ownership of my code (maybe I should have said "shortcomings") and he's not been responsive. I fear that I may come off as aggressive when I ask him to explain his changes to me. He's just a quiet person who keeps to himself, but his actions continue. I don't want to banish him from making code changes (not like I could), because we are a team--but I want to do my part to help our team. Added clarifications: We share 1 development branch. I do not wait until all my changes complete a single task because I risk losing some significant work--so I make sure my changes build and do not break anything. My concern is that my teammate doesn't explain the reason or purpose behind his changes. I don't think he should need my blessing, but if we disagree on an approach I thought it would be best to discuss the pros and cons and make a decision once we both understand what is going on. I have not discussed this with our team lead yet as I would prefer to resolve personal disagreements without getting management involved unless it is necessary. Since my concern seemed more of personal issue than a threat to our work, I chose to not bother the team lead. I am working on code review process ideas--to help promote the benefits of more organized code reviews without making it all about my pet peeves.

• Our Favorite Highlights from OpenWorld 2012

  - by Kathy.Miedema

  By Kathy Miedema and Misha Vaughan, Oracle Applications User Experience The Oracle Applications User Experience (UX) team’s activities around OpenWorld expand every year, but this year we certainly raised the bar.   Members of our team helped deliver three, separate, all-day training events in the week prior to OpenWorld. Our Fusion User Experience Advocates (FXA) and Applications UX Sales Ambassadors (SAMBA) have all-new material around the Oracle user experience to deliver at conferences in the coming year - Fusion Applications design patterns, mobile design patterns, and the new face of Fusion. We also delivered a hands-on workshop sharing user experience tools for our customers that is designed to answer this question: "If I have no UX staff, what do I do?" We also spent the weeks just before OpenWorld preparing to talk about the new face of Fusion Applications, a greatly simplified entry experience into Fusion Applications for self-service users, CRM users, and IT managers who want to change the look and feel quickly. Special thanks to Oracle ACE Director Floyd Teter for the first mention of our project.Jeremy Ashley, VP, Oracle Applications User Experience Customers may have seen one of the many OpenWorld session demos of the new face of Fusion, which will be available with Fusion Applications soon. It was shown in sessions by Oracle's Chris Leone, Anthony Lye, and our own Vice President, Jeremy Ashley, among others.   Leone reinforced the importance of user experience as one of three main design principles for Fusion Applications, emphasizing that Fusion was designed from the beginning to be intelligent, social, and mobile. User experience highlights of the new face of Fusion, he said, included the need for "zero training," and he called the experience "easy to use." He added that deploying it for HCM self-service would be effortless.  Customers take part in a usability lab tour during OpenWorld 2012. Customers also may have seen the new face of Fusion on the demogrounds or during one of our teams' chartered lab tours at the end of the week. We tested other new designs at our on-site lab in the Intercontinental Hotel, next to Moscone West. Applications User Experience team members show eye-tracking and mobile demos at OOW. We were also excited to kick off new branches of the Oracle Usability Advisory Board, which now has groups in Latin America and the Middle East, in addition to North America and EMEA.   And we were pleasantly surprised by the interest in one of our latest research projects, Oracle Voice, which is designed to enable faster data input for on-the-go users. We offer a big thank-you to the Nuance demopod for sharing the demo with OpenWorld attendees.  For more information on our program and products like the new face of Fusion, please comment below.

• Data Model Dissonance

  - by Tony Davis

  So often at the start of the development of database applications, there is a premature rush to the keyboard. Unless, before we get there, we’ve mapped out and agreed the three data models, the Conceptual, the Logical and the Physical, then the inevitable refactoring will dog development work. It pays to get the data models sorted out up-front, however ‘agile’ you profess to be. The hardest model to get right, the most misunderstood, and the one most neglected by the various modeling tools, is the conceptual data model, and yet it is critical to all that follows. The conceptual model distils what the business understands about itself, and the way it operates. It represents the business rules that govern the required data, its constraints and its properties. The conceptual model uses the terminology of the business and defines the most important entities and their inter-relationships. Don’t assume that the organization’s understanding of these business rules is consistent or accurate. Too often, one department has a subtly different understanding of what an entity means and what it stores, from another. If our conceptual data model fails to resolve such inconsistencies, it will reduce data quality. If we don’t collect and measure the raw data in a consistent way across the whole business, how can we hope to perform meaningful aggregation? The conceptual data model has more to do with business than technology, and as such, developers often regard it as a worthy but rather arcane ceremony like saluting the flag or only eating fish on Friday. However, the consequences of getting it wrong have a direct and painful impact on many aspects of the project. If you adopt a silo-based (a.k.a. Domain driven) approach to development), you are still likely to suffer by starting with an incomplete knowledge of the domain. Even when you have surmounted these problems so that the data entities accurately reflect the business domain that the application represents, there are likely to be dire consequences from abandoning the goal of a shared, enterprise-wide understanding of the business. In reading this, you may recall experiences of the consequence of getting the conceptual data model wrong. I believe that Phil Factor, for example, witnessed the abandonment of a multi-million dollar banking project due to an inadequate conceptual analysis of how the bank defined a ‘customer’. We’d love to hear of any examples you know of development projects poleaxed by errors in the conceptual data model. Cheers, Tony

• Lookup Viewer

  - by Geertjan

  The Maven integrated view that I showed yesterday I was able to create because I happened to know that an implementation of SubprojectProvider and LogicalViewProvider are in the Lookup of Maven projects. With that knowledge, I was able to use and even delegate to those implementations. But what if you don't know that those implementations are in the Lookup of the Project object? In the case of the Maven Project implementation, you could look in the source code of the Maven Project implementation, at the "getLookup" method. However, any other module could be putting its own objects into that Lookup, dynamically, i.e., at runtime. So there's no way of knowing what's in the Lookup of any Project object or any other object with a Lookup. But now imagine that you have a Lookup Viewer, as a tool during development, which you would exclude when distributing the application. Whenever new objects are found in the Lookup, the viewer displays them. You could install the Lookup Viewer into NetBeans IDE, or any other NetBeans Platform application, and then get a quick impression of what's actually in the Lookup when you select a different item in the application during development. Here it is (though I vaguely remember someone else writing something similar): Above, a Maven Project is selected. The Lookup Window shows that, among many other classes, an implementation of SubprojectProvider and LogicalViewProvider are found in the Lookup when the Maven Project is selected. If an item in the Lookup Window has its own Lookup, the content of that Lookup is displayed as child nodes of the Lookup, etc, i.e., you can explore all the way down the Lookup of each item found within objects found within the current selection. (What's especially fun is seeing the SaveCookieImpl being added and removed from the Lookup Window when you make/save a change in a document.) Another example is below, showing the Lookup Window installed in a custom application created during a course at MIT in Boston: A small trick I had to apply is that I always show the previous Lookup, since the current Lookup, when you select one of the Nodes in the Lookup Window, would be the Lookup of the Lookup Window itself! If anyone is interested in this, I can publish the NetBeans module providing the above window to the NetBeans update center.

• NetBeans IDE 7.3 Knows Null

  - by Geertjan

  What's the difference between these two methods, "test1" and "test2"? public int test1(String str) {     return str.length(); } public int test2(String str) {     if (str == null) {         System.err.println("Passed null!.");         //forgotten return;     }     return str.length(); } The difference, or at least, the difference that is relevant for this blog entry, is that whoever wrote "test2" apparently thinks that the variable "str" may be null, though did not provide a null check. In NetBeans IDE 7.3, you see this hint for "test2", but no hint for "test1", since in that case we don't know anything about the developer's intention for the variable and providing a hint in that case would flood the source code with too many false positives:  Annotations are supported in understanding how a piece of code is intended to be used. If method return types use @Nullable, @NullAllowed, @CheckForNull, the value is considered to be "strongly possible to be null", as well as if the variable is tested to be null, as shown above. When using @NotNull, @NonNull, @Nonnull, the value is considered to be non-null. (The exact FQNs of the annotations are ignored, only simple names are checked.) Here are examples showing where the hints are displayed for the non-null hints (the "strongly possible to be null" hints are not shown below, though you can see one of them in the screenshot above), together with a comment showing what is shown when you hover over the hint: There isn't a "one size fits all" refactoring for these various instances relating to null checks, hence you can't do an automated refactoring across your code base via tools in NetBeans IDE, as shown yesterday for class member reordering across code bases. However, you can, instead, go to Source | Inspect and then do a scan throughout a scope (e.g., current file/package/project or combinations of these or all open projects) for class elements that the IDE identifies as potentially having a problem in this area: Thanks to Jan Lahoda, who reports that this currently also works in NetBeans IDE 7.3 dev builds for fields but that may need to be disabled since right now too many false positives are returned, for help with the info above and any misunderstandings are my own fault!

• Interesting Topics in Comp. Sci. for New Students?

  - by SoulBeaver

  I hope this is the right forum to ask this question. Last friday I was in a discussion with my professors about the students' lack of motivation and interest in the field of Computer Science. All of the students are enrolled, but through questionnaires and other questions that my professor posed it was revealed that over 90% of all enrolled students are just in it for the reward of getting a job sometime in the future (since it's a growing field with high job potential) I asked my professor for the permission to take over the first couple of lectures and try and motivate, interest and inspire students for the field of Computer Science and programming in particular (this is the Intro to Programming course). This request was granted and I now have a week to come up with a lecture topic for my professor's five groups. My main goal isn't to teach, I just want to get students to be as interested in the field as I am. I want to show them what's possible, what awesome magical things have been done in the field, the future we are heading towards using programming and Comp. Sci. Therefore, I would like to pose this question: I have a few topics, materials and sample projects that I would like to talk about: -- Grace Hopper (It is my hope to interest the female programmers in the class. There are never more than two or three per group and they, more than males, are prone to jumping ship and abandoning Comp. Sci.) -- The Singularity Institute -- Alan Turing -- Robotics -- Programming not as a chore or a must, but the idea that we are, at our core, the nexus to which anything anybody does in the digital world is connected to. We are the problem solvers; we assemble all the parts together and we are the ones that, essentially, make the vision a reality. -- Give them an idea for a programming project which, through the help of the professor, could be significant to every student (I want students to not only feel interested in the topic, but they should feel important, that what they do here makes a difference) Do you have interesting topics worthy of discussion, something I can tell the students which they can get interested about? How would you approach the lecture? If you had 90 minutes worth of time to try and get students interested in the project, what would you do?

• 2D SAT Collision Detection not working when using certain polygons (With example)

  - by sFuller

  My SAT algorithm falsely reports that collision is occurring when using certain polygons. I believe this happens when using a polygon that does not contain a right angle. Here is a simple diagram of what is going wrong: Here is the problematic code: std::vector<vec2> axesB = polygonB->GetAxes(); //loop over axes B for(int i = 0; i < axesB.size(); i++) { float minA,minB,maxA,maxB; polygonA->Project(axesB[i],&minA,&maxA); polygonB->Project(axesB[i],&minB,&maxB); float intervalDistance = polygonA->GetIntervalDistance(minA, maxA, minB, maxB); if(intervalDistance >= 0) return false; //Collision not occurring } This function retrieves axes from the polygon: std::vector<vec2> Polygon::GetAxes() { std::vector<vec2> axes; for(int i = 0; i < verts.size(); i++) { vec2 a = verts[i]; vec2 b = verts[(i+1)%verts.size()]; vec2 edge = b-a; axes.push_back(vec2(-edge.y,edge.x).GetNormailzed()); } return axes; } This function returns the normalized vector: vec2 vec2::GetNormailzed() { float mag = sqrt( x*x + y*y ); return *this/mag; } This function projects a polygon onto an axis: void Polygon::Project(vec2* axis, float* min, float* max) { float d = axis->DotProduct(&verts[0]); float _min = d; float _max = d; for(int i = 1; i < verts.size(); i++) { d = axis->DotProduct(&verts[i]); _min = std::min(_min,d); _max = std::max(_max,d); } *min = _min; *max = _max; } This function returns the dot product of the vector with another vector. float vec2::DotProduct(vec2* other) { return (x*other->x + y*other->y); } Could anyone give me a pointer in the right direction to what could be causing this bug? Edit: I forgot this function, which gives me the interval distance: float Polygon::GetIntervalDistance(float minA, float maxA, float minB, float maxB) { float intervalDistance; if (minA < minB) { intervalDistance = minB - maxA; } else { intervalDistance = minA - maxB; } return intervalDistance; //A positive value indicates this axis can be separated. } Edit 2: I have recreated the problem in HTML5/Javascript: Demo

• Managing accounts on a private website for a real-life community

  - by Smudge

  Hey Pro Webmasters, I'm looking at setting-up a walled-in website for a real-life community of people, and I was wondering if anyone has any experience with managing member accounts for this kind of thing. Some conditions that must be met: This community has a set list of real-life members, each of whom would be eligible for one account on the website. We don't expect or require that they all sign-up. It is purely opt-in, but we anticipate that many of them would be interested in the services we are setting up. Some of the community members emails are known, but some of them have fallen off the grid over the years, so ideally there would be a way for them to get back in touch with us through the public-facing side of the site. (And we'd want to manually verify the identity of anyone who does so). Their names are known, and for similar projects in the past we have assigned usernames derived from their real-life names. This time, however, we are open to other approaches, such as letting them specify their own username or getting rid of usernames entirely. The specific web technology we will use (e.g. Drupal, Joomla, etc) is not really our concern right now -- I am more interested in how this can be approached in the abstract. Our database already includes the full member roster, so we can email many of them generated links to a page where they can create an account. (And internally we can require that these accounts be paired with a known member). Should we have them specify their own usernames, or are we fine letting them use their registered email address to log-in? Are there any paradigms for walled-in community portals that help address security issues if, for example, one of their email accounts is compromised? We don't anticipate attempted break-ins being much of a threat, because nothing about this community is high-profile, but we do want to address security concerns. In addition, we want to make the sign-up process as painless for the members as possible, especially given the fact that we can't just make sign-ups open to anyone. I'm interested to hear your thoughts and suggestions! Thanks!
