• Just Another Web Service (JAWS) vs SOA

  Over the last few years SOA has been a hot topic lending it to be abused by many that have no understanding of the concept. In my opinion, one of the largest issues facing SOA is the lack of understanding and experience implementing SOA by business and IT alike. I just recently deployed a new web services that is called by multiple service clients. Would you call this SOA because it is a web service that can be called by any requesting client? In my opinion, this is not SOA; instead it is Just Another Web Service (JAWS).  Just because a company creates a web service does not mean that they are using SOA, in fact it only means that they are using a web service. SOA is an architectural style that focuses on the design of systems based on the consumer and providers thorough the use of contracts.  With this approach SOA needs to be applied for the top down in order for it to reach its full potential. In the case of the web service, the service is just a small part of the entire system that is reusable and has the flexibility to change. In order for a company in this case to move towards SOA then they need to define business processes that can be shared through the use of reusable software and loose coupling. Once the company’s thought and development process change to address changes in this manner they can start to become more SOA.

• 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!

Spirent’s customers require high levels of support for a diverse and complex product portfolio, and the company is committed to delivering on this requirement. Spirent needed a solution to help its customers get the information they need quickly and at their convenience through its Web site. After evaluating several solutions, Spirent selected and deployed Oracle Knowledge for Web Self Service Enterprise Edition. Oracle Knowledge Management uses natural language processing to understand the true intent of each inquiry logged via the support portal’s search function.

• .NET development on Macs

  - by Jeff

  I posted the “exciting” conclusion of my laptop trade-ins and issues on my personal blog. The links, in chronological order, are posted below. While those posts have all of the details about performance and software used, I wanted to comment on why I like using Macs in the first place. It started in 2006 when Apple released the first Intel-based Mac. As someone with a professional video past, I had been using Macs on and off since college (1995 graduate), so I was never terribly religious about any particular platform. I’m still not, but until recently, it was staggering how crappy PC’s were. They were all plastic, disposable, commodity crap. I could never justify buying a PowerBook because I was a Microsoft stack guy. When Apple went Intel, they removed that barrier. They also didn’t screw around with selling to the low end (though the plastic MacBooks bordered on that), so even the base machines were pretty well equipped. Every Mac I’ve had, I’ve used for three years. Other than that first one, I’ve also sold each one, for quite a bit of money. Things have changed quite a bit, mostly within the last year. I’m actually relieved, because Apple needs competition at the high end. Other manufacturers are finally understanding the importance of industrial design. For me, I’ll stick with Macs for now, because I’m invested in OS X apps like Aperture and the Mac versions of Adobe products. As a Microsoft developer, it doesn’t even matter though… with Parallels, I Cmd-Tab and I’m in Windows. So after three and a half years with a wonderful 17” MBP and upgraded SSD, it was time to get something lighter and smaller (traveling light is critical with a toddler), and I eventually ended up with a 13” MacBook Air, with the i7 and 8 gig upgrades, and I love it. At home I “dock” it to a Thunderbolt Display.

• Which problem(s) do YOU want to see solved?

  - by buu700

  My team and I are meeting tonight to come up with a business plan and some community input would be amazing. I've been mulling over this issue for the past few months and bouncing ideas off of others, and now I'd finally like some input from the community. I have come up with a fair selection of ideas, but most of those amount to either fun projects which could potentially be profitable, or otherwise solid business models that have one or two major hurdles (usually related to resources or legality). For our team meeting tonight, my idea is to take inventory of our available skills, resources, and compelling problems which interest us. The last is where I would greatly appreciate some community input. Hell, even entire business ideas/plans would be appreciated. No matter how big or small your thoughts, any input would be appreciated. We're a team of computer scientists, so our business will be primarily based around software/technology/Web solutions. Among my relevant available resources (entire Internet aside), I have the following: A pretty reliable connection to an SEO company a large production company. A stash of fairly powerful server hardware. A fast network with static IPs. The backend for Hackswipe, which includes credit card payment processing and a Google Voice-based SMS gateway. This work in progress design for something completely unrelated but which is backed by some fairly decent infrastructure. Direct access to the experts in just about any relevant field (on-campus Carnegie Mellon professors). A sexual relationship with the baron of a small nation. For further down the line, some investor relationships. Not likely to be so relevant, but a decent social media presence (Stack Overflow reputation, modship in some major reddits, various tech forums). The source code for Eugene fucking McCabe. Pooled with the other team members, the list of projects we can build off of would be longer (including an Android app). So, what are your thoughts? Crossposted to reddit

• Is paper indispensable in a programmer's everyday work?

  - by rwong

  As a programmer who work in a company whose vision is to make paperless office possible, is there any way I can work effectively while using less paper? I can list at least several kinds of papers I use quite often: Paper notebook, on which I do most of the pre-coding design work and ideas Books Temporary printouts of source code, though not so often (in color, with a 6 point font at 600 DPI) Sticky note, to remind myself of things that should be taken care of within a few days On the other hand, I also use a wiki and an office text editor. Once a while I would use a diagramming software to make a few flowcharts. Deeper questions: Is there a relationship between paper use and productivity? How can programmers help save the trees? Is paperless software development fundamentally different from paperless office? Related questions: Do you ever write code with pen and paper, and should we do it more often? What physical tools do you find useful to work as a programmer? What things are essential on a programmer's desk? Stuff every programmer needs while working Additional info, if it helps: Everyone has dual monitors. We have decent project management and issue tracking software (both web-based). Please be constructive. In particular, please give your answer to your peer programmers who wish to be flexible and are willing to change working style in order to become more productive as well as meeting certain their own personal values. Edited: I removed the company's view because it appears to be too flamebait. If you need to see my original words, go to the edit history. Deleted: Doxygen and whiteboard. Reason: disregarding my personal experience with these great tools, we never had to print out anything as a consequence of using/not using them. To see my original words, go to the edit history.

• Akka react vs receive

  - by Will I Am

  I am reading my way through Akka tutorials, but I'd like to get my feet wet with a real-life scenario. I'd like to write both a connectionless UDP server (an echo/ping-pong service) and a TCP server (also an echo service, but it keeps the connection open after it replies). My first question is, is this a good experimental use case for Akka, or am I better served with more common paradigms like IOCP? Would you do something like this with Akka in production? Although I understand conceptually the difference between react() and receive(), I struggle to choose one or the other for the two models. In the UDP model, there is no concept of who the sender is on the server, once the pong is sent, so should I use receive()? In the TCP model, the connection is maintained on the server after the pong, so should I use react()? If someone could give me some guidance, and maybe an opinion on how you'd design these two use cases, it would take me a long way. I have found a number of examples, but they didn't have explanations as to why they chose the paradigms they did.

• Masters or Second Bachelors Degree..or neither

  - by drD

  I have a degree in Business Administration, because at the time I didn't know what I wanted to do. I have been interested in programming for the past 2 years and have taken some action to self-teach. My experience/ knowledge base is limited to the following: -Read Kochan's Programming in C -Read IOS and Objective-C from the Big Nerd Ranch series -Obtained a C++ at NYU - thought it would be a good way to start to get a grasp on OO & design I would like to continue developing my skills, but most of all, re-orient how I am perceived as a professional. I am fully aware of how much a novice to this subject and would greatly appreciate any guidance anyone could give me. I currently have a job so full-time is not an option My goal is to become a software/ applications developer My questions are: -Should i take up a second bachelors in computer science? or a masters? or continue taking professional certificate programs (how are these viewed?) -If masters in computer science, would that make sense, if I dont have the formal foundation? (being a chief without ever being an Indian) -General advice for a novice to develop skill Thank You in advanced for helping me out.

• Good SLA

  - by PointsToShare

  © 2011 Dov Trietsch What is a good SLA? I have frequently pondered about Service Level Agreements (SLA). Yesterday after ordering and while waiting, and waiting, and waiting for the food to arrive, I passed the time reading and re-reading the restaurant menu (again and again..) until I noticed their very interesting SLA.   Because (as promised) we had to wait even longer and the conversation around me was mostly in Russian, I ended doodling some of my thoughts of the menu, on the menu. People are both providers and consumers of services. As a service consumer – maybe the SLA above sucks – though to be honest, had the service been better, I would not have noticed this and you, the reader, would have been spared this rambling monograph. As a provider, I think it’s great! Because I provide services in the form of business software, I extend the idea to the following principles of design: 1: Wygiwyg. You guessed it. What You Get Is What You Get. 2: Ugiwugi.  U Get It When U Get It. How’s this for a developer friendly SLA? I’ll never be off the spec, or late. And BTW, the food was good, so when I finally got what I got, I liked it. That's All Folks!!

• BizTalk: Dynamic SMTP Port: Unknown Error Description

  - by Leonid Ganeline

  Today I investigated one strange error working with Dynamic SMTP Port.   Event Type: Error Event Source: BizTalk Server 2006 Event Category: BizTalk Server 2006 Event ID: 5754 Date: ******** Time: ********AM User: N/A Computer: ******** Description: A message sent to adapter "SMTP" on send port "*********" with URI "mailto:********.com" is suspended. Error details: Unknown Error Description  MessageId:  {********} InstanceID: {********}   My code was pretty simple and the source of the error was hidden somewhere inside it.   msg_MyMessage(SMTP.CC) = var_CC; msg_MyMessage(SMTP.From) = var_From; msg_MyMessage(SMTP.Subject) = var_Subject; msg_MyMessage(SMTP.EmailBodyText) = var_Message;    // #1    msg_MyMessage(SMTP.SMTPHost) = " localhost "; msg_MyMessage(SMTP.SMTPAuthenticate) = 0; When I added line #2, this frustrating error disappeared.    msg_MyMessage(SMTP.EmailBodyTextCharset) = "UTF-8"; // #2 Conclusion: If we use the SMTP.EmailBodyText property, we must set up the SMTP.EmailBodyTextCharset property. To me it looks like a bug in BizTalk. [Maybe it is "by design", but in this case give us a useful error text!!!] And don't ask me how much time I've spent with this investigation.

• Hill International Wins Oracle Eco-Enterprise Innovation Award

  - by Evelyn Neumayr

  In my last blog entry, I discussed Oracle’s Eco-Enterprise Innovation Award, part of the Oracle Excellence awards. Nominations for this year’s awards are due July 17. These awards are presented to organizations that use Oracle products to reduce their environmental footprint while improving their operational efficiency. One of last year’s winners was Hill International. Engineering News-Record magazine recently ranked Hill as the eighth-largest construction management firm in the United States. Hill International was able to streamline its forecasting and improve its visibility into its construction projects’ productivity and profitability using Oracle Primavera. They also implemented Oracle Hyperion Financial Management to standardize its financial reporting and forecasting processes and support its decision-making. With Oracle, Hill gained visibility into the true productivity of each project and cut its financial reporting cycle time from two weeks to one. The company also used the data generated to support new construction project proposals and determine the profitability of potential projects. Hill International realized significant cost savings and reduced its environmental impact on its US$400 million Comcast Center construction project in Philadelphia by centralizing its data storage, reducing paper usage, and maximizing project efficiency. It also leveraged the increased visibility offered by the Oracle solutions to make more environmentally-sound business decisions regarding on-site demolition, re-use of previous structures, green design of new facilities, procurement, and materials usage. See more about Hill International and the other Eco-Enterprise Innovation award winners here.

• Should I pick up a functional programming language?

  - by Statement

  I have recently been more concerned about the way I write my code. After reading a few books on design patterns (and overzealous implementation of them, I'm sure) I have shifted my thinking greatly toward encapsulating that which change. I tend to notice that I write less interfaces and more method-oriented code, where I love to spruce life into old classes with predicates, actions and other delegate tasks. I tend to think that it's often the actions that change, so I encapsulate those. I even often, although not always, break down interfaces to a single method, and then I prefer to use a delegate for the task instead of forcing client code to create a new class. So I guess it then hit me. Should I be doing functional programming instead? Edit: I may have a misconception about functional programming. Currently my language of choice is C#, and I come from a C++ background. I work as a game developer but I am currently unemployed. I have a great passion for architecture. My virtues are clean, flexible, reusable and maintainable code. I don't know if I have been poisoned by these ways or if it is for the better. Am I having a refactoring fever or should I move on? I understand this might be a question about "use the right tool for the job", but I'd like to hear your thoughts. Should I pick up a functional language? One of my fear factors is to leave the comfort of Visual Studio.

• Spotlight on an Office – Reading TVP offices

  - by Maria Sandu

  This month we’re in the UK at the Reading offices, for ‘Spotlight on an office’. The Reading Office, which is Oracle’s UK Headquarters, is based in Thames Valley Park (TVP), which is a bustling hive of activity that houses many different companies, a gym, and even a nursery. Overlooking the Thames and some of England’s beautiful countryside, this office, just a short free bus ride from Reading Town Centre is in a fantastic location. The offices themselves are made up of 5 different buildings, each with their own car park, restaurant, and design. The main building or TVP 510 as it is referred to, sits resplendent next to an extremely blue (for the UK) pond, filled with large koi-carp that on a sunny day like to come to the surface of the lake and bask. As the main hub of activity, TVP 510 is where you will find our Dry Cleaning service, the Ozone Gym, the main restaurant (which never fails to have someone in it), and the Marquee which sits outside the back amongst the picnic benches, and is where we have Barbeques in the summer time. Another highlight of the Reading Offices is tucked away in TVP530; the home of H20, and our sports and social club. This is the building that can be best be described as having the ‘cool’ vibe, where you can relax and unwind, all whilst sipping a Starbucks (or Costa if you prefer, located in TVP550), and playing a game of Pool in the cafeteria, or alternatively you can sit back and enjoy a seat in one of the luxury massage chairs! If you feel so inclined, you can also hire out an OraBike from any of the TVP offices, and if you are anything like some of my team, cycle from Reading to Bath using the towpath starting in Thames Valley Park. Oracle’s Reading Offices are a great place to work, they are home to a diverse range of people and have great atmosphere which would suit a graduate, intern, or anyone who is looking to come and work for Oracle in the UK.

• Algorithm to use for shop floor layout?

  - by jkohlhepp

  I ran into a classroom problem yesterday (business oriented class, not computer science) and I found it interesting from an algorithmic perspective. The problem goes something like this: Assume there is a shop floor with N different rooms, and you have N different departments that need to go in those rooms. The departments and the rooms are all the same size, so any department could go in any room. There is a known travel distance from each room to each other room. There is also a known amount of trips necessary from one department to another (trips are counted the same regardless which room they originate from, so a trip from A to B is equivalent to a trip from B to A). Given those inputs, determine a layout of departments into rooms which minimizes travel time. What is the best way to approach this problem algorithmically? Is there already a particular algorithm or class of algorithms designed to solve this type of problem? Does this type of problem have a name in computer science? I am not looking for you to design an algorithm to solve this, although feel free to do so if you would like. I'm wondering if this is a problem space that has already been well defined and studied algorithmically and if so get some links to research further. I can see a lot of different data structures and algorithms that might apply to this and I'm curious which approach would be "best". And don't worry, you are not doing my homework for me. This is not a homework problem per se, as this is a business course and we were simply discussing the concepts and not trying to solve the problem algorithmically.

• Is it customary to write Java domain objects / data transfer objects with public member variables on mobile platforms?

  - by Sean Mickey

  We performed a code review recently of mobile application Java code that was developed by an outside contractor and noticed that all of the domain objects / data transfer objects are written in this style: public class Category { public String name; public int id; public String description; public int parentId; } public class EmergencyContact { public long id; public RelationshipType relationshipType; public String medicalProviderType; public Contact contact; public String otherPhone; public String notes; public PersonName personName; } Of course, these members are then accessed directly everywhere else in the code. When we asked about this, the developers told us that this is a customary performance enhancement design pattern that is used on mobile platforms, because mobile devices are resource-limited environments. It doesn't seem to make sense; accessing private members via public getters/setters doesn't seem like it could add much overhead. And the added benefits of encapsulation seem to outweigh the benefits of this coding style. Is this generally true? Is this something that is normally done on mobile platforms for the reasons given above? All feedback welcome and appreciated -

• Observable Adapter

  - by Roman Schindlauer

  .NET 4.0 introduced a pair of interfaces, IObservable<T> and IObserver<T>, supporting subscriptions to and notifications for push-based sequences. In combination with Reactive Extensions (Rx), these interfaces provide a convenient and uniform way of describing event sources and sinks in .NET. The StreamInsight CTP refresh in November 2009 included an Observable adapter supporting “reactive” event inputs and outputs.   While we continue to believe it enables an important programming model, the Observable adapter was not included in the final (RTM) release of Microsoft StreamInsight 1.0. The release takes a dependency on .NET 3.5 but for timing reasons could not take a dependency on .NET 4.0. Shipping a separate copy of the observable interfaces in StreamInsight – as we did in the CTP refresh – was not a viable option in the RTM release.   Within the next months, we will be shipping another preview of the Observable adapter that targets .NET 4.0. We look forward to gathering your feedback on the new adapter design! We plan to include the Observable adapter implementation into the product in a future release of Microsoft StreamInsight.

• Better ways to have valuable data indexed, which is ignored currently

  - by Sam

  <a title="">.../a> Hi folks. It seems that my title tag which holds extremely valuable and describes contents on my simple design page is currently compeltely denied by search engines and not indexed at all!! Those descriptions should however be indexed as the describe valuable portions to an otherwise empty page with clean glossary (thats neat and organised to the eye of the viewer. So putting all that descriptive data into visible space would ruin the designish less is more fundamental... So, which alternatives to the title tag do I have, in order to put important contents that are relevant for both user as well as search engines? A <a name="">......</> B <p name="">......</> C <a alt="">.......</> D <p alt="">.......</> From the above list, arose my question: Which of the above is advisable alternative in order to get the valuable actual content indexed? Should it be in a a tag or p tag? Or are there even better tags for this which still keep layout clean? You suggestions are Much appreciated!

• Dealing with 2D pixel shaders and SpriteBatches in XNA 4.0 component-object game engine?

  - by DaveStance

  I've got a bit of experience with shaders in general, having implemented a couple, very simple, 3D fragment and vertex shaders in OpenGL/WebGL in the past. Currently, I'm working on a 2D game engine in XNA 4.0 and I'm struggling with the process of integrating per-object and full-scene shaders in my current architecture. I'm using a component-entity design, wherein my "Entities" are merely collections of components that are acted upon by discreet system managers (SpatialProvider, SceneProvider, etc). In the context of this question, my draw call looks something like this: SceneProvider::Draw(GameTime) calls... ComponentManager::Draw(GameTime, SpriteBatch) which calls (on each drawable component) DrawnComponent::Draw(GameTime, SpriteBatch) The SpriteBatch is set up, with the default SpriteBatch shader, in the SceneProvider class just before it tells the ComponentManager to start rendering the scene. From my understanding, if a component needs to use a special shader to draw itself, it must do the following when it's Draw(GameTime, SpriteBatch) method is invoked: public void Draw(GameTime gameTime, SpriteBatch spriteBatch) { spriteBatch.End(); spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend, null, null, null, EffectShader, ViewMatrix); // Draw things here that are shaded by the "EffectShader." spriteBatch.End(); spriteBatch.Begin(/* same settings that were set by SceneProvider to ensure the rest of the scene is rendered normally */); } My question is, having been told that numerous calls to SpriteBatch.Begin() and SpriteBatch.End() within a single frame was terrible for performance, is there a better way to do this? Is there a way to instruct the currently running SpriteBatch to simply change the Effect shader it is using for this particular draw call and then switch it back before the function ends?

• Defunct website taken over by spammer. How to stop them?

  - by Robert

  A friend of mine used to publish a small literary fiction magazine, both in print and on the web. In 2011 she announced that she was quitting, put a note on the website, and carefully unwound the subscriptions. She continued hosting the site (with all the back-issues available for free) until the beginning of this year, when she let the hosting lapse and the domain name expire. Today she discovered that some unknown person has purchased her former domain name and put up a modified version of her entire site. The design is different but all the content is the same, including all of the back-issues of the magazine (and the stories by diverse authors contained within), their cover art, news posts, and even her contact information. All the content would have been available from Archive.org, so it's no mystery how they got it. The only thing noticeably changed is a column added to the front page titled "Favorite Videos", with around 35 links to Youtube videos. The links are named things like "Video (Worry)" and "Video (Squirting)" and the videos all feature a man named Leo giving dubious advice and promoting his life-coaching website. Here's one of the suspect videos. There does not appear to be any connection between the content of the videos and my friend or her magazine. I also posted to the Security StackExchange to ask why someone would do this and what the security risks are to her. What I want to know here is, what can she do to stop them? To be clear she doesn't want the domain name back. She just doesn't want her name and copyrighted material used deceptively. Also, what (if anything) could she have done when shutting down her website to avoid this happening?

• Is there a visual web application builder or rapid webapp prototyping framework?

  - by Jesper Mortensen

  Question: Is there such a thing as a self-hosted framework or CMS especially tailored towards the creation of interactive web applications without -- or with an absolute minimum of -- programming? (Substantially less programming than say a simple Rails app or a plugin for Wordpress, Joomla etc would require.) As for desired features I'd settle for whatever is available, but some ideas could be: A User authentication and Permissions system. A GUI-driven input form builder. A GUI-driven template / visual site design builder. A simple scripting language (think AppleScript-like simplicity) A highly modular architecture, with high-level business objects (users, forms data, etc) exposed for easy re-use. If something like the above doesn't exist, then what comes near this? Need: This is for self-hosted rapid prototyping of web applications, and limited user testing of webapp user interface designs in a closed user test. Notes: I know about Ruby on Rails (Rails), Django, Pyramid etc. I'm looking for something much faster to work in, for making prototypes. I know about CMS's in general but find that most of them are tailored towards displaying information to the end users. If there is an exceptionally easy-to-master CMS with easy scripting (lets say much more so than for example Wordpress) then I'd be interested.

• Doing powerups in a component-based system

  - by deft_code

  I'm just starting really getting my head around component based design. I don't know what the "right" way to do this is. Here's the scenario. The player can equip a shield. The the shield is drawn as bubble around the player, it has a separate collision shape, and reduces the damage the player receives from area effects. How is such a shield architected in a component based game? Where I get confused is that the shield obviously has three components associated with it. Damage reduction / filtering A sprite A collider. To make it worse different shield variations could have even more behaviors, all of which could be components: boost player maximum health health regen projectile deflection etc Am I overthinking this? Should the shield just be a super component? I really think this is wrong answer. So if you think this is the way to go please explain. Should the shield be its own entity that tracks the location of the player? That might make it hard to implement the damage filtering. It also kinda blurs the lines between attached components and entities. Should the shield be a component that houses other components? I've never seen or heard of anything like this, but maybe it's common and I'm just not deep enough yet. Should the shield just be a set of components that get added to the player? Possibly with an extra component to manage the others, e.g. so they can all be removed as a group. (accidentally leave behind the damage reduction component, now that would be fun). Something else that's obvious to someone with more component experience?
