• Does Open Source lead to bad coding?

  - by David Conde

  I have a thought that I tried asking at SO, but didnt seem like the appropriate place. I think that source sites like Google Code, GitHub, SourceForge... have played a major role in the history of programming. However, I found that there is another bad thing to these kind of sites and that is you may just "copy" code from almost anyone, not knowing if it is good(tested) source or not. This line of thought has taken me to believe that source code websites tend to lead many developers (most likely unexperienced) to copy/paste massive amounts of code, which I find just wrong. I really dont know how to focus the question well, but basic thought would be: Is this ok? Is Open Source contributing to that or I'm just seeing ghosts... Hope people get interested because I think this is an important theme.

• Testing on Device Other Than the Known Brand Question (Local and Imported Phone Question)

  - by David Dimalanta

  I have a question. When testing a device by using Eclipse, it's easy to install and add device software with these specific brands commonly used in game testing like Samsung, Google, T-Mobile, and HTC; according to the Android Developers website. What if I'm using other brands that runs on Android to test the program via Eclipse (i.e. MyPhone, Starmobile), what should I look for to download in order to enable testing phones that those brands are using other than the brands that are known and commonly used: model number or simply brand? Here's some examples of these brands other than the brands we've known that runs on Android: Starmobile Engage 7 (http://www.lazada.com.ph/Starmobile-Engage-7-Android-40-4GB-with-Wi-Fi-Black-Starmobile-Mercury-B201-COMBO-39833.html/) My|Phone A898 Duo (http://www.myphone.com.ph/#!a898-duo/c1yt) Also, take note that I'm a Filipino programmer working at the Philippines to test our local smartphones for the created Android game or app. Hope you can understand me for my help.

• What incidentals do server maintenance people/devs need?

  - by SeniorShizzle

  I'm trying to put together a thank-you package for clients who are server-side developers and in charge of their company's servers and databases. Since I've never been in that line of work before, I would like to know what it is like. Get inside your heads, for instance. My first thought was (don't hate me) a few patch cables. I don't know if you guys actually need these often or anything. What are some similar things that you like or need for your lives at work. Small incidentals less than $10 are preferred, like Coffee or a notebook, screwdrivers. Et cetera.

• Oracle Response to Apache Departure from JCP

  - by Henrik Ståhl

  Last month Oracle renominated Apache to the Java Executive Committee because we valued their active participation and perspective on Java. Earlier this week, by an overwhelming majority, the Java Executive Committee voted to move Java forward by formally initiating work on both Java SE 7 and SE 8 based on their technical merits. Apache voted against initiating technical committee work on both SE 7 and SE 8, effectively voting against moving Java forward. Now, despite supporting the technical direction, Apache have announced that they are quitting the Executive Committee. Oracle has a responsibility to move Java forward and to maintain the uniformity of the Java standard for the millions of Java developers and the majority of Executive Committee members agree. We encourage Apache to reconsider its position and remain a part of the process to move Java forward. ASF and many open source projects within it are an important part of the overall Java ecosystem.

• C++ - Constructor or Initialize Method to Startup

  - by Bob Fincheimer

  I want to determine when to do non-trivial initialization of a class. I see two times to do initialization: constructor and other method. I want to figure out when to use each. Choice 1: Constructor does initialization MyClass::MyClass(Data const& data) : m_data() { // does non-trivial initialization here } MyClass::~MyClass() { // cleans up here } Choice 2: Defer initialization to an initialize method MyClass::MyClass() : m_data() {} MyClass::Initialize(Data const& data) { // does non-trivial initialization here } MyClass::~MyClass() { // cleans up here } So to try and remove any subjectivity I want to figure out which is better in a couple of situations: Class that encapsulates a resource (window/font/some sort of handle) Class that composites resources to do something (a control/domain object) Data structure classes (tree/list/etc.) [Anything else you can think of] Things to analyze: Performance Ease of use by other developers How error-prone/opportunities for bugs [Anything else you can think of]

• Content, MetaData and Taxonomy 1 Taxonomy Manager

  This article is cross-posted from my personal blog. In DotNetNuke version 5.3, we introduced the concept of a centralized Content store, together with the ability to apply Taxonomies (categories) to the content. We have extended this in DNN 5.4 by completing the MetaData API as well as adding Folksonomy (user tags). In this series of blogs I will explain how developers can take advantage of these new features in their own extensions. But first lets take a look at how the pieces work together....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How important is positive feedback in code reviews?

  - by c_maker

  Is it important to point out the good parts of the code during a code review and the reasons why it is good? Positive feedback might be just as useful for the developer being reviewed and for the others that participate in the review. We are doing reviews using an online tool, so developers can open reviews for their committed code and others can review their code within a given time period (e.g. 1 week). Others can comment on the code or other reviewer's comments. Should there be a balance between positive and negative feedback?

• Improve your Application Performance with .NET Framework 4.0

  Nice Article on CodeGuru. This processors we use today are quite different from those of just a few years ago, as most processors today provide multiple cores and/or multiple threads. With multiple cores and/or threads we need to change how we tackle problems in code. Yes we can still continue to write code to perform an action in a top down fashion to complete a task. This apprach will continue to work; however, you are not taking advantage of the extra processing power available. The best way to take advantage of the extra cores prior to .NET Framework 4.0 was to create threads and/or utilize the ThreadPool. For many developers utilizing Threads or the ThreadPool can be a little daunting. The .NET 4.0 Framework drastically simplified the process of utilizing the extra processing power through the Task Parallel Library (TPL). This article talks following topics “Data Parallelism”, “Parallel LINQ (PLINQ)” and “Task Parallelism”. span.fullpost {display:none;}

• Why do people hesitate using Python 3?

  - by Ham

  Python 3 has been released in December 2008. A lot of time has passed since then but still today many developers hesitate using Python 3. Even popular frameworks like Django are not compatible with Python 3 yet but still rely on Python 2. Sure, Python 3 has some incompatibilities to Python 2 and some people need to rely on backwards-compatibility. But hasn't Python 3 been around long enough now for most projects to switch or start with Python 3? Having two competiting versions has so many drawbacks; two branches need to be maintained, confusion for learners and so on, so why is there such a big hesitation throughout the Python community in switching to Python 3?

• Where to find clients?

  - by Zenph

  My main area: web development. Of course, I don't expect anybody give away their 'gold mine' or whatever but I am struggling to see where I should be advertising my services. I have one other developer I work with and we have a lot of happy clients - on freelance websites. Thing is, freelance websites just seem to suck the life out of you when you're being out-bidded by ridiculous rates. I want to attract customers who are more concerned about quality and accountability than price. Any suggestions at all? I'm so lost with this. EDIT: Added bounty of 200 - all of my 'reputation'. EDIT: Added second bounty of 50 I did hear of a novel idea. Do work for an opensource project and get featured in their 'trusted developers' section, if they have one. Input?

• Web Developer interview questions

  - by Baba

  I read an article today that listed some basic questions about web development: Describe how POST data was submitted to a server by a browser. Explain a number of HTTP status codes (except maybe 404 and 500). Explain SOLID or name a design pattern. Explain ways to improve a page load speed or user experience. The author says "if you can’t answer the questions above there are a lot of people who wouldn’t think of you as a Senior Web Developer." My questions are: How relevant are these questions in respect to real life web programming and scalability? How true is that statement? In other words, do you consider this knowledge a requirement to be considered a Senior Web Developer? I was able to answer all the questions, too easily it seemed, so I'm wondering whether it is effective to use these or similar questions to screen developers rather than asking them to write sample code.

• Agile social media analysis and implementation

  - by blunders

  Are there any books/platforms for social media campaign planning and implementation that define a completely agile approach to engaging audiences on platforms such as Facebook, Linkedin, Twitter, etc? UPDATE: Posted a bounty on the question since the current answer is really not about agile approaches to social media campaign planning and implementation. UPDATE 2: The question is asking for an agile social media approach, or a social media platform that has agile social media approach baked-in. If the question was about an agile approach to software development, SCRUM would be the most likely answer (70% percent of agile software developers say they practice some from of SCRUM), and Pivotal Tracker might be one of many agile platforms suggested; as a generalization Pivotal Tracker might be called a project management platform. On the flip-side, suggesting just a social media platform might be the equivalent of suggesting a project management platform, and suggesting I see if SCRUM works on it. Problem is that if you haven't suggested an agile social media approach to try on this social media platform, then you haven't provided an answer to the question.

• Wisdom of using open source code in a commercial software product

  - by Mr. Jefferson

  I'm looking at using some open source code in my ASP.NET web app (specifically dapper). Management is not a fan, because open source is seen as a risk that has bitten us before. Apparently previous developers have had to rewrite things after having open-source components fail. The pros seem to be: It does a lot of stuff for me that would otherwise involve either lots of boilerplate code or Microsoft's recommended but slower solution (Entity Framework). Cons: It's complex enough that if it were to fail suddenly in production, I would be hard pressed to fix it. However, it's in use on a much higher-traffic site than mine, so I don't think it'll end up being a high risk portion of the project. What is the consensus here? Is it unwise to use open source code in my project that I don't know/understand as well as I do my own code?

• Hot: Pre-built Developer VMs from OTN

  - by Justin Kestelyn

  For those of you who haven't already played with it, Oracle VM VirtualBox is an awfully cool desktop virtualization tool. Even better, it's free. We OTN-ers like it even more than you will though because it allows us to freeze-dry entire software stacks into VM images. Developers can simply download a few files, assemble them with a script we provide, and then import and run the resulting pre-built VM in VirtualBox. Voila, instant (insert name here) stack. These VMs are particularly handy in support of in-person workshops, but there's no reason we can't make them available for everyone. Which we have done, in Java, database, and SOA/BPM flavors. (All "ingredients" are listed at the referenced link, and they are extensive.) Now that we have the kinks worked out, other flavors are sure to become available in 2011. Now go get 'em!

• What you don't like in your web-framework of "choice"?

  - by 0101

  Most of the time we don't have a choice were it comes to web-frameworks, in Java every company is using a different one(big thanks to web-framework developers - you will burn in hell). However now I have a choice of picking which framework we will use, I will probably pick the one I know the best since I know how to by-pass its downfalls. In every comparation we will only see what is good in that frameworks and any downfalls will be swept under the carpet. What are the downfalls of most known frameworks?

• Should Swing knowledge be required from Java programmers?

  - by Anto

  Swing is an integral part of the Java API. It is also the most popular GUI framework for Java. I still wonder, should every Java programmer still know, or at least be pretty familiar with, Swing (possibly excluding web developers)? There are alternatives (e.g. SWT), but they are not very widely used (compared to Swing). What do you think about requiring Swing knowledge from Java programmers? If such knowledge is important, to what degree? Are the basics enough or not? The reason I wonder is because I really don't like Swing but wonder if I still should brush up my skills in it. I'm able to create simple GUIs in it, but I would definitely not say that I know Swing well.

• Continuous integration - build Debug and Release every time?

  - by Darian Miller

  Is it standard practice when setting up a Continuous Integration server to build a Debug and Release version of each project? Most of the time developers code with a Debug mode project configuration set enabled and there could be different library path configurations, compiler defines, or other items configured differently between Debug/Release that would cause them to act differently. I configured my CI server to build both Debug & Release of each project and I'm wondering if I'm just overthinking it. My assumption is that I'll do this as long as I can get quick feedback and once that happens, then push the Release off to a nightly build perhaps. Is there a 'standard' way of approaching this?

• Blog Buzz - Devoxx 2011

  - by Janice J. Heiss

  Some day I will make it to Devoxx – for now, I’m content to vicariously follow the blogs of attendees and pick up on what’s happening.  I’ve been doing more blog "fishing," looking for the best commentary on 2011 Devoxx. There’s plenty of food for thought – and the ideas are not half-baked.The bloggers are out in full, offering useful summaries and commentary on Devoxx goings-on.Constantin Partac, a Java developer and a member of Transylvania JUG, a community from Cluj-Napoca/Romania, offers an excellent summary of the Devoxx keynotes. Here’s a sample:“Oracle Opening Keynote and JDK 7, 8, and 9 Presentation•    Oracle is committed to Java and wants to provide support for it on any device.•    JSE 7 for Mac will be released next week.•    Oracle would like Java developers to be involved in JCP, to adopt a JSR and to attend local JUG meetings.•    JEE 7 will be released next year.•    JEE 7 is focused on cloud integration, some of the features are already implemented in glassfish 4 development branch.•    JSE 8 will be release in summer of 2013 due to “enterprise community request” as they can not keep the pace with an 18    month release cycle.•    The main features included in JSE8 are lambda support, project Jigsaw, new Date/Time API, project Coin++ and adding   support for sensors. JSE 9 probably will focus on some of these features:1.    self tuning JVM2.    improved native language integration3.    processing enhancement for big data4.    reification (adding runtime class type info for generic types)5.    unification of primitive and corresponding object classes6.    meta-object protocol in order to use type and methods define in other JVM languages7.    multi-tenancy8.    JVM resource management” Thanks Constantin! Ivan St. Ivanov, of SAP Labs Bulgaria, also commented on the keynotes with a different focus.  He summarizes Henrik Stahl’s look ahead to Java SE 8 and JavaFX 3.0; Cameron Purdy on Java EE and the cloud; celebrated Java Champion Josh Bloch on what’s good and bad about Java; Mark Reinhold’s quick look ahead to Java SE 9; and Brian Goetz on lambdas and default methods in Java SE 8. Here’s St. Ivanov’s account of Josh Bloch’s comments on the pluses of Java:“He started with the virtues of the platform. To name a few:    Tightly specified language primitives and evaluation order – int is always 32 bits and operations are executed always from left  to right, without compilers messing around    Dynamic linking – when you change a class, you need to recompile and rebuild just the jar that has it and not the whole application    Syntax  similarity with C/C++ – most existing developers at that time felt like at home    Object orientations – it was cool at that time as well as functional programming is today    It was statically typed language – helps in faster runtime, better IDE support, etc.    No operator overloading – well, I’m not sure why it is good. Scala has it for example and that’s why it is far better for defining DSLs. But I will not argue with Josh.”It’s worth checking out St. Ivanov’s summary of Bloch’s views on what’s not so great about Java as well. What's Coming in JAX-RS 2.0Marek Potociar, Principal Software Engineer at Oracle and currently specification lead of Java EE RESTful web services API (JAX-RS), blogged on his talk about what's coming in JAX-RS 2.0, scheduled for final release in mid-2012.  Here’s a taste:“Perhaps the most wanted addition to the JAX-RS is the Client API, that would complete the JAX-RS story, that is currently server-side only. In JAX-RS 2.0 we are adding a completely interface-based and fluent client API that blends nicely in with the existing fluent response builder pattern on the server-side. When we started with the client API, the first proposal contained around 30 classes. Thanks to the feedback from our Expert Group we managed to reduce the number of API classes to 14 (2 of them being exceptions)! The resulting is compact while at the same time we still managed to create an API that reflects the method invocation context flow (e.g. once you decide on the target URI and start setting headers on the request, your IDE will not try to offer you a URI setter in the code completion). This is a subtle but very important usability aspect of an API…” Obviously, Devoxx is a great Java conference, one that is hitting this year at a time when much is brewing in the platform and beginning to be anticipated.
