• Configuring Weblogic Server 10.3.6 from 32-bit mode to 64-bit mode

  - by Ekta Malik

  This post pertains to the configuration of Weblogic Server from 32-bit mode to 64-bit mode on Solaris OS. Just in case, you have WLS 10.3.6 running in 32-bit mode and the JDK being used is installed for 64-bit mode [On Solaris OS, JDK 64-bit installation comprises of installing 32-bit JDK followed by a patch for 64-bit JDK].  Verification of the mode being used One can verify the mode of Weblogic Server in the following ways Either check the commonEnv.sh script located at $MIDDLEWARE_HOME/wlserver_10.3/common/bin where $MIDDLEWARE_HOME refers to the install directory of Middleware. Look for the patterns - SUN_ARCH_DATA_MODEL and JAVA_USE_64BIT in the file. For 32-bit mode, the parameters would appear as shown belowSUN_ARCH_DATA_MODEL="32"JAVA_USE_64BIT=false Check the server console logs; which JDK is being used during start-up By checking which JDK is used by the running process of Weblogic Server Configuration Steps Take a backup of the commonEnv.sh script located at $MIDDLEWARE_HOME/wlserver_10.3/common/bin where $MIDDLEWARE_HOME refers to the install directory of Middleware Modify the commonEnv.sh script for the following parameters: The values should be 64 and true respectively for 64-bit modeSUN_ARCH_DATA_MODEL="64"JAVA_USE_64BIT=true  Restart the weblogic server. One can confirm that the JDK being used is 64-bit by looking at the Weblogic console logs during server start up or by looking at the running process.

• The Hot-Add Memory Hogs

  - by Andrew Clarke

  One of the more difficult tasks, when virtualizing a server, is to determine the amount of memory that Hypervisor should assign to the virtual machine. This requires accurate monitoring and, because of the consequences of setting the value too low, there is a great temptation to err on the side of over-provisioning. This results in fewer guest VMs and, in fact, with more accurate memory provisioning, many virtual environments could support 30% more VMs. In order to achieve a better consolidation (aka VM density) ratio, Windows Server 2008 R2 SP1 has introduced what Microsoft calls ‘Dynamic Memory’. This means that the start-up RAM VM memory assigned to guest virtual machines can be allowed to vary according to demand, changing dynamically while the VM is running, based on the workload of applications running inside. If demand outstrips supply, then memory can be rationed according to the ‘memory weight’ assigned to the guest VM. By this mechanism, memory becomes a shared resource that can be reallocated automatically as demand patterns vary. Unlike VMWare’s Memory Overcommit technology, the sum of all the memory allocations to each virtual machine will not exceed the total memory of the host computer. This is fine for applications that are self-regulating in their demands for memory, releasing memory back into the 'pool' when not under peak load. Other applications however, such as SQL Server Standard and Enterprise, are by nature, memory hogs under high workload; they can grab hot-add memory whilst running under load and then never release it. This requires more careful setting-up and the SQLOS team have provided some guidelines from for configuring SQL Server in virtual environments. Whereas VMWare’s Memory Overcommit is well-proven in a number of different configurations, Hyper-V’s ‘Dynamic Memory’ is new. So far, the indications are that it will improve the business case for virtualizing and it is probably a far more intuitive technology for the average IT professional to grasp. It is certainly worth testing to see whether it works for you.

• How should I architect my Model and Data Access layer objects in my website?

  - by Robin Winslow

  I've been tasked with designing Data layer for a website at work, and I am very interested in architecture of code for the best flexibility, maintainability and readability. I am generally acutely aware of the value in completely separating out my actual Models from the Data Access layer, so that the Models are completely naive when it comes to Data Access. And in this case it's particularly useful to do this as the Models may be built from the Database or may be built from a Soap web service. So it seems to me to make sense to have Factories in my data access layer which create Model objects. So here's what I have so far (in my made-up pseudocode): class DataAccess.ProductsFromXml extends DataAccess.ProductFactory {} class DataAccess.ProductsFromDatabase extends DataAccess.ProductFactory {} These then get used in the controller in a fashion similar to the following: var xmlProductCreator = DataAccess.ProductsFromXml(xmlDataProvider); var databaseProductCreator = DataAccess.ProductsFromXml(xmlDataProvider); // Returns array of Product model objects var XmlProducts = databaseProductCreator.Products(); // Returns array of Product model objects var DbProducts = xmlProductCreator.Products(); So my question is, is this a good structure for my Data Access layer? Is it a good idea to use a Factory for building my Model objects from the data? Do you think I've misunderstood something? And are there any general patterns I should read up on for how to write my data access objects to create my Model objects?

• Is browser fingerprinting a viable technique for identifying anonymous users?

  - by SMrF

  Is browser fingerprinting a sufficient method for uniquely identifying anonymous users? What if you incorporate biometric data like mouse gestures or typing patterns? The other day I ran into the Panopticlick experiment EFF is running on browser fingerprints. Of course I immediately thought of the privacy repercussions and how it could be used for evil. But on the other hand, this could be used for great good and, at the very least, it's a tempting problem to work on. While researching the topic I found a few companies using browser fingerprinting to attack fraud. And after sending out a few emails I can confirm at least one major dating site is using browser fingerprinting as but one mechanism to detect fake accounts. (Note: They have found it's not unique enough to act as an identity when scaling up to millions of users. But, my programmer brain doesn't want to believe them). Here is one company using browser fingerprints for fraud detection and prevention: http://www.bluecava.com/ Here is a pretty comprehensive list of stuff you can use as unique identifiers in a browser: http://browserspy.dk/

• Is it bad practice for services to share a database in SOA?

  - by Paul T Davies

  I have recently been reading Hohpe and Woolf's Enterprise Integration Patterns, some of Thomas Erl's books on SOA and watching various videos and podcasts by Udi Dahan et al. on CQRS and Event Driven systems. Systems in my place of work suffer from high coupling. Although each system theoretically has its own database, there is a lot of joining between them. In practice this means there is one huge database that all systems use. For example, there is one table of customer data. Much of what I've read seems to suggest denormalising data so that each system uses only its database, and any updates to one system are propagated to all the others using messaging. I thought this was one of the ways of enforcing the boundaries in SOA - each service should have its own database, but then I read this: http://stackoverflow.com/questions/4019902/soa-joining-data-across-multiple-services and it suggests this is the wrong thing to do. Segregating the databases does seem like a good way of decoupling systems, but now I'm a bit confused. Is this a good route to take? Is it ever recommended that you should segregate a database on, say an SOA service, an DDD Bounded context, an application, etc?

• Designing a Content-Based ETL Process with .NET and SFDC

  - by Patrick

  As my firm makes the transition to using SFDC as our main operational system, we've spun together a couple of SFDC portals where we can post customer-specific documents to be viewed at will. As such, we've had the need for pseudo-ETL applications to be implemented that are able to extract metadata from the documents our analysts generate internally (most are industry-standard PDFs, XML, or MS Office formats) and place in networked "queue" folders. From there, our applications scoop of the queued documents and upload them to the appropriate SFDC CRM Content Library along with some select pieces of metadata. I've mostly used DbAmp to broker communication with SFDC (DbAmp is a Linked Server provider that allows you to use SQL conventions to interact with your SFDC Org data). I've been able to create [console] applications in C# that work pretty well, and they're usually structured something like this: static void Main() { // Load parameters from app.config. // Get documents from queue. var files = someInterface.GetFiles(someFilterOrRegexPattern); foreach (var file in files) { // Extract metadata from the file. // Validate some attributes of the file; add any validation errors to an in-memory // structure (e.g. List<ValidationErrors>). if (isValid) { var fileData = File.ReadAllBytes(file); // Upload using some wrapper for an ORM or DAL someInterface.Upload(fileData, meta.Param1, meta.Param2, ...); } else { // Bounce the file } } // Report any validation errors (via message bus or SMTP or some such). } And that's pretty much it. Most of the time I wrap all these operations in a "Worker" class that takes the needed interfaces as constructor parameters. This approach has worked reasonably well, but I just get this feeling in my gut that there's something awful about it and would love some feedback. Is writing an ETL process as a C# Console app a bad idea? I'm also wondering if there are some design patterns that would be useful in this scenario that I'm clearly overlooking. Thanks in advance!

• Math questions at a programmer interview?

  - by anon

  So I went to an interview at Samsung here in Dallas, Texas. The way the recruiter described the job, he didn't make it sound like it was too math-oriented. The job basically involved graphics programming and C++. Yes, math is implied in graphics programming, especially shaders, but I still wasn't expecting this... The whole interview lasted about an hour and a half and they asked me nothing but math-related questions. They didn't ask me a single programming question, which I found odd. About all they did was ask me how to write certain math routines as a C++ function, but that's about it. What about programming philosophy questions? Design patterns? Code-correctness? Constness? Exception safety? Thread safety? There are a zillion topics that they could have covered. But they didn't. The main concern I have is that they didn't ask any programming questions. This basically implies to me that any programmer who is good at math can get a job here, but they might put out terrible code. Of course, I think I bombed the interview because I haven't used any sort of linear algebra in about a year and I forget math easily if I haven't used it in practice for a while. Are any of my other fellow programmers out there this way? I'm a game programmer too, so this seems especially odd. The more I learn, the more old knowledge that gets "popped" out of my "stack" (memory). My question is: Does this interview seem suspicious? Is this a typical interview that large corporations have? During the interview they told me that Google's interview process is similar. They have multiple, consecutive interviews where the math problems get more advanced.

• Which open source PHP project has the 'perfect' OOP design I can learn from?

  - by aditya menon

  I am a newbie to OOP, and I learn best by example. You could say this question is similar to Which Scala open source projects should I study to learn best coding practices - but in PHP. I have heard-tell that Symfony has the best 'architecture' (I will not pretend I know what that exactly means), as well as Doctrine ORM. Is it worth it to spend many months reading the source code of these projects, trying to deduce the patterns used and learning new tricks? I have seen equal number of web pages dissing and liking Zend's codebase (will provide links if deemed necessary). Do you know of any other project that would make any veteran OOP developer shed tears of joy? Please let me add that practicality and scope of use is not a concern at all here - I just want to do: Pick a project that has a codebase deemed awesome by devs way better and greater than me. Write code that achieves what the project does. Compare results and try to learn what I don't know. Basically, an academic interest codebase. Any recommendations please?

• Hallmarks of a Professional PHP Programmer

  - by Scotty C.

  I'm a 19 year old student who really REALLY enjoys programming, and I'm hoping to glean from your years of experience here. At present, I'm studying PHP every chance I get, and have been for about 3 years, although I've never taken any formal classes. I'd love to some day be a programmer full time, and make a good career of it. My question to you is this: What do you consider to be the hallmarks or traits of a professional programmer? Mainly in the field of PHP, but other, more generalized qualifications are also more than welcome, as I think PHP is more of a hobbyist language and may not be the language of choice in the eyes of potential employers. Please correct me if I'm wrong. Above all, I don't want to wast time on something that isn't worth while. I'm currently feeling pretty confident in my knowledge of PHP as a language, and I know that I could build just about anything I need and have it "work", but I feel sorely lacking in design concepts and code structure. I can even write object oriented code, but in my personal opinion, that isn't worth a hill of beans if it isn't organized well. For this reason, I bought Matt Zandstra's book "PHP Objects, Patterns, and Practice" and have been reading that a little every day. Anyway, I'm starting to digress a little here, so back to the original question. What advice would you give to an aspiring programmer who wants to make an impact in this field? Also, on a side note, I've been working on a project with a friend of mine that would give a fairly good idea of where I'm at coding wise. I'm gonna give a link, I don't want anyone to feel as though I'm pushing or spamming here, so don't click it if you don't want to. But if you are interested on giving some feedback there as well, you can see the code on github. I'm known as The Craw there. https://github.com/PureChat/PureChat--Beta-/tree/

• Staying OO and Testable while working with a database

  - by Adam Backstrom

  What are some OOP strategies for working with a database but keeping thing testable? Say I have a User class and my production environment works against MySQL. I see a couple possible approaches, shown here using PHP: Pass in a $data_source with interfaces for load() and save(), to abstract the backend source of data. When testing, pass a different data store. $user = new User( $mysql_data_source ); $user-load( 'bob' ); $user-setNickname( 'Robby' ); $user-save(); Use a factory that accesses the database and passes the result row to User's constructor. When testing, manually generate the $row parameter, or mock the object in UserFactory::$data_source. (How might I save changes to the record?) class UserFactory { static $data_source; public static function fetch( $username ) { $row = self::$data_source->get( [params] ); $user = new User( $row ); return $user; } } I have Design Patterns and Clean Code here next to me, but I'm struggling to find applicable concepts.

• Is there a resource that explains the benefits of layered programming?

  - by P.Brian.Mackey

  Some developers I know favor what I would call a procedural programming style. I recognize that procedural programming has its uses, albeit not in the business application world of .NET programming. So let's say we have a winform application with a buttonclick event. The buttonclick handles everything from the UI configuration to the database call and data manipulation. So you end up with a method that is 100's of lines of code long. Outside the fact that this code can't be considered test-able for various reasons, this style of programming is fragile to change. I can talk bout OO, Anti-patterns, etc. The problem is that any distinct topic I can dream up requires a great deal of explanation to understand the potential benefits. Outside of finding a new job (lots of businesses program this way), how can I teach these kinds of developers how to write better code? Obviously we can't sit around a round table and discuss pro's and con's all day due to time constraints and real work that has to be done. Although, training and intense training is the only thing I can think of to fix these problems. Not to say I write perfect code, I most certainly do not. I do believe there are certain best practices that should be followed as a rule E.G. OO in the context of .NET. The most common excuse I hear is "we can't write code fast enough if we do it like that".

• How to improve Algorithmic Programming Solving skill? [closed]

  - by gaurav

  Possible Duplicate: How can I improve my problem-solving ability? How do you improve your problem solving skills? Should I learn design patterns or algorithms to improve my logical thinking skills? What to do when you're faced with a problem that you can't solve quickly? Are there non-programming related activities akin to solving programming problems? I am a computer engineering graduate. I have studied programming since three years. I am good in coding and programming. I have been trying to compete in algorithmic competitions on sites such as topcoder,spoj since one and a half year, but I am still unable to solve problems other than too easy problems. I have learned from people that it takes practice to solve such problems. I try to solve those problems but sometimes I am unable to understand and even if I do understand I am unable to think of a good algorithm for solving it. Even if I solve I get Wrong answer and I am unable to figure out what is the problem with my code as it works on samples given on the sites but fails on test cases which they do not provide. I really want to solve those problems and become good in algorithms. I have read books for learning algorithms like Introduction to algorithms by CLRS,practicing programming questions. I have gone through some questions but they don't answer this question. I have seen the questions which are said duplicates but those questions focus on overall programming, but I am asking for algorithm related programming, basically for competing in programming which involve solving a problem statement then online judge will automatically evaluate it, such type of programming is quite different from the type of programming these questions discuss.

• Advice on a good comeback strategy after years of java abstinence

  - by simou

  It's almost 5 yrs since I left the java IT-project/enterprise business. Before I was a highly skilled enterprise developer / OO architect with more than 10 years experience in the business. I was proficient in many of those enterprise related technologies, including DWHing. Since then I haven't been doing any large scale programming, a little bit of C, Python, some dips into Scala, hacking a small java-plugin framework, opengl, but only as fun projects. Now I want to re-enter the java stage again, i.e. I'm looking for job opportunities as a developer. But I fear I might have lost much of my former punching strength, e.g. I would have to give my SQL knowledge a deep refreshing breath, re-visit basic stuff like design patterns, enterprise architectures, etc. and probably learn the new stuff like EJB3.1, JEE 6 too. I also missed the whole scrum craze. So from your own experience, what subject should I tackle first? Like technology (which ones?) or design skills (uml..)? But what I'm also wondering is since the basic design / architectural principles haven't changed much by now, what would be the chance on the job market for someone like me who left the java-world at a time where everything was less fragmented and EJB2.1 and XDoclet were de-facto standards? And how could I convince a potential employer that I'm still an effective on-the-job learner? Should I rather aim for "junior positions" ? Lots of questions but I'd be really glad if you could share your (encouraging :) thoughts with me. cheers! (btw I'm based in Austria)

• How can you Add Value to your Mobile Apps?

  - by Carlos Chang

  Author: Craig Mikus, Sr. Director, Enterprise Mobile Solutions Seems like every customer is either building or planning to build mobile apps, especially customer facing apps. Why? Inevitably, all companies want to improve the customer experience through more quality interactions that drive customer satisfaction, customer loyalty, new revenue streams, and even improve the way they service their customers. What better way than mobile apps? Right? But how can customers add more value to these mobile apps to drive more business benefit? Look closely, the answer just might be right in front of you. Still need another clue? What’s the first 4 letters of mobile – mo-bi? Or pronounced differently, More BI. That’s right – add more business intelligence to your overall mobile strategy. In today’s customer centric world where customer interactions and personalization are critical, it’s important to leverage a BI strategy that complements and feeds into your mobile strategy. For example, I was recently talking to a customer that was implementing a data warehouse project focused customer analytics. Their goal was to understand who are their best customers and why, develop customer profiles, identify customer trends & patterns, identify cross sell opportunities, and much more. The company then wanted to feed this information to marketing for targeted campaigns and programs. As we continued to talk, I asked my contact if they had plans to feed this information into their customer facing mobile apps to personalize the apps, target their interactions, and hopefully drive customer loyalty and new revenue streams? Two minutes later, my contact was calling his mobile development teams. So my advice to everyone, as you establish your enterprise mobile strategy and goals, remember that “mo-BI” is a critical component to add value to your mobile apps! So make sure you have “mo BI” in your mobile strategy. As I come to think of it, did you ever notice that Big Data also starts with BI?

• Effective versus efficient code

  - by Todd Williamson

  TL;DR: Quick and dirty code, or "correct" (insert your definition of this term) code? There is often a tension between "efficient" and "effective" in software development. "Efficient" often means code that is "correct" from the point of view of adhering to standards, using widely-accepted patterns/approaches for structures, regardless of project size, budget, etc. "Effective" is not about being "right", but about getting things done. This often results in code that falls outside the bounds of commonly accepted "correct" standards, usage, etc. Usually the people paying for the development effort have dictated ahead of time what it is that they value more. An organization that lives in a technical space will tend towards the efficient end, others will tend towards the effective. Developers often refuse to compromise their favored approach for the other. In my own experience I have found that people with formal education in software development tend towards the Efficient camp. Those that picked up software development more or less as a tool to get things done tend towards the Effective camp. These camps don't get along very well. When managing a team of developers who are not all in one camp it is challenging. In your own experience, which camp do you land in, and do you find yourself having to justify your approach to others? To management? To other developers?

• WPF and Composite Application Library &ndash; Missing The Point

  - by David Totzke

  I have a headache and it’s not even 9AM yet.  Well, ok, it’s nearly ten here now in GMT –5 but it’s before nine somewhere still. Sometimes people will miss the point of something so utterly and completely that one is left wondering how such a person can even dress themselves. Writing an application using WPF and the Composite Application Library (Prism) means that one must learn the various programming idioms common to these frameworks.  The Windows Forms event driven model simply will not suffice.  You need to come to grips with the idea of a very loosely coupled application.  Concepts that must be absorbed and internalized include Data Binding, Control and Data Templates, Commands, Dependency Injection, and Inversion of Control, as well as the Supervising Controller, Presentation Model and Model-View-View-Model patterns. It is as simple as that.  Not to embrace these concepts is to invite pain.  It is to invite noodles; and not the holy kind. Someone actually said to me that “just because it’s not WPF, doesn’t mean it’s wrong.”  And he’s right.  Unless, of course, you are writing a WPF application and especially if you are using the Composite Application Library. In simple terms then; YOU’RE DOING IT WRONG!   Dave Just because I can…

• Need help deciding if Joomla! experience as a good metric for hiring a particular prospective employee.

  - by Stephen

  My company has been looking to hire a PHP developer. Some of the requirements for the job include: an understanding of design patterns, particularly MVC. some knowledge of PHP 5.3's new features. experience working with a PHP framework (it doesn't matter which one). I interviewed a man today who's primary work experience involved working with Joomla!. As an employee, he will be required to work on existing and new web applications that use Zend Framework, CakePHP and/or CodeIgniter. It is my opinion that we shouldn't dismiss hiring a developer just because he has not used the same technologies that he'll be using on the job. So, I'd like to know about the kind of coding experience working with Joomla! can provide. I've never bothered to take more than a brief look (if that) at the Joomla! package, so I'm hoping to lean on the knowledge of my peers. Would you consider Joomla! to contain a professional code-base? Is the package well organized, and/or OO in general, or is it more like WordPress where logic and presentation are commingled? When working with Joomla!, is the developer encouraged to use best practices? In your opinion, would experience working with Joomla! garner the skills needed to get up to speed with Zend or CakePHP quickly, or will there be a steep learning curve ahead of the developer? I'm not saying that Joomla! is a bad technology, or even that it is lower on the totem pole when compared to the frameworks I've mentioned. Maybe it's awesome, I dunno. I simply have no idea!
