  • Online examples for software design diagrams

    - by Gerenuk
    Do you know where I can find a good example of software design diagrams and specs on the internet? Like UML, specs and similar. I'd like to understand this approach better. Before I just started coding and now I'd like plan more in advance. By diagrams I don't mean made-up examples, but something that would actually be used. Also it shouldn't be so trivial that there is no use of using diagrams. Ideally it shouldn't be too large either. Do you know a good online source? (this question is about online resources and specific examples only. it is not asking about books or advise how to learn software design.)

  • Identity Globe Trotters (Sep Edition): The Social Customer

    - by Tanu Sood
    Welcome to the inaugural edition of our monthly series - Identity Globe Trotters. Starting today, the last Friday of every month, we will explore regional commentary on Identity Management. We will invite guest contributors from around the world to share their opinions and experiences around Identity Management and highlight regional nuances, specific drivers, solutions and more. Today's feature is contributed by Michael Krebs, Head of Business Development at esentri consulting GmbH, a (SOA) specialized Oracle Gold Partner based in Ettlingen, Germany. In his current role, Krebs is dealing with the latest developments in Enterprise Social Networking and the Integration of Social Media within business processes.  By Michael Krebs The relevance of "easy sign-on" in the age of the "Social Customer" With the growth of Social Networks, the time people spend within those closed "eco-systems" is growing year by year. With social networks looking to integrate search engines, like Facebook announced some weeks ago, their relevance will continue to grow in contrast to the more conventional search engines. This is one of the reasons why social network accounts of the users are getting more and more like a virtual fingerprint. With the growing relevance of social networks the importance of a simple way for customers to get in touch with say, customer care or contract departments, will be crucial for sales processes in critical markets. Customers want to have one single point of contact and also an easy "login-method" with no dedicated usernames, passwords or proprietary accounts. The golden rule in the future social media driven markets will be: The lower the complexity of the initial contact, the better a company can profit from social networks. If you, for example, can generate a smart way of how an existing customer can use self-service portals, the cost in providing phone support can be lowered significantly. Recruiting and Hiring of "Digital Natives" Another particular example is "social" recruiting processes. The so called "digital natives" don´t want to type in their profile facts and CV´s in proprietary systems. Why not use the actual LinkedIn profile? In German speaking region, the market in the area of professional social networks is dominated by XING, the equivalent to LinkedIn. A few weeks back, this network also opened up their interfaces for integrating social sign-ons or the usage of profile data for recruiting-purposes. In the European (and especially the German) employment market, where the number of young candidates is shrinking because of the low birth rate in the region, it will become essential to use social-media supported hiring processes to find and on-board the rare talents. In fact, you will see traditional recruiting websites integrated with social hiring to attract the best talents in the market, where the pool of potential candidates has decreased dramatically over the years. Identity Management as a key factor in the Customer Experience process To create the biggest value for customers and also future employees, companies need to connect their HCM or CRM-systems with powerful Identity management solutions. With the highly efficient Oracle (social & mobile enabling) Identity Management solution, enterprises can combine easy sign on with secure connections to the backend infrastructure. This combination enables a "one-stop" service with personalized content for customers and talents. In addition, companies can collect valuable data for the enrichment of their CRM-data. The goal is to enrich the so called "Customer Experience" via all available customer channels and contact points. Those systems have already gained importance in the B2C-markets and will gradually spread out to B2B-channels in the near future. Conclusion: Central and "Social" Identity management is key to Customer Experience Management and Talent Management For a seamless delivery of "Customer Experience Management" and a modern way of recruiting the best talent, companies need to integrate Social Sign-on capabilities with modern CX - and Talent management infrastructure. This lowers the barrier for existing and future customers or employees to get in touch with sales, support or human resources. Identity management is the technology enabler and backbone for a modern Customer Experience Infrastructure. Oracle Identity management solutions provide the opportunity to secure Social Applications and connect them with modern CX-solutions. At the end, companies benefit from "best of breed" processes and solutions for enriching customer experience without compromising security. About esentri: esentri is a provider of enterprise social networking and brings the benefits of social network communication into business environments. As one key strength, esentri uses Oracle Identity Management solutions for delivering Social and Mobile access for Oracle’s CRM- and HCM-solutions. …..End Guest Post…. With new and enhanced features optimized to secure the new digital experience, the recently announced Oracle Identity Management 11g Release 2 enables organizations to securely embrace cloud, mobile and social infrastructures and reach new user communities to help further expand and develop their businesses.

  • Ogre3D : seeking advices about game files management

    - by Tibor
    I'm working on a new game, and its related level editor, based on Ogre3D. I was thinking about how i could manage the game files, knowing that Ogre use .mesh files for models, .material for materials/texture information etc... . At first i thought about a common .zip folder decompressed at runtime (the same way Torchlight and Ogre samples do). But this way the game assets become a monolithic archive, loading takes time, and could be difficult to eventually patch them. So, let's say i have a game object named "Cube" i want to load in my program. Going for modularity, what if i create a compressed file (using zlib compression routines) named Cube.extname, containing its sub-files Cube.mesh, Cube.material and so on ? Are there any alternatives or should i stick with compressed objects? PS: Just to clear things, the answer is unrelated to my program code, at the moment i'm using "resources.cfg" pointing to the OgreSDK media directory.

  • Switching between levels, re-initialize existing structure or create new one?

    - by Martino Wullems
    This is something I've been wondering for quite a while. When building games that exist out of multiple levels (platformers, shmups etc) what is the prefered method to switch between the levels? Let's say we have a level class that does the following: Load data for the level design (tiles), enemies, graphics etc. Setup all these elements in their appriopate locations and display them Start physics and game logic I'm stuck between the following 2 methods: 1: Throw away everything in the level class and make a new one, we have to load an entirely new level anyway! 2: pause the game logic and physics, unload all currents assets, then re-initialize those components with the level data for the new level. They both have their pros and cons. Method 1 is alot easier and seems to make sense since we have to redo everything anyway. But method 2 allows you to re-use exisiting elements which might save resources and allows for a smoother transfer to the new level.

  • Interview question: How would you implement Google Search?

    - by ripper234
    Supposed you were asked in an interview "How would you implement Google Search?" How would you answer such a question? There might be resources out there that explain how some pieces in Google are implemented (BigTable, MapReduce, PageRank, ...), but that doesn't exactly fit in an interview. What overall architecture would you use, and how would you explain this in a 15-30 minute time span? I would start with explaining how to build a search engine that handles ~ 100k documents, then expand this via sharding to around 50M docs, then perhaps another architectural/technical leap. This is the 20,000 feet view. What I'd like is the details - how you would actually answer that in an interview. Which data structures would you use. What services/machines is your architecture composed of. What would a typical query latency be? What about failover / split brain issues? Etc...

  • User eXperience

    - by Daniel Moth
    The last few months I have been spending a lot of time designing (and help design) the developer experience for the areas I contribute to (in future versions of Visual Studio). As a technical person who defines feature sets, it is easy to get engulfed in the pure technical side of things and ignore the details that ultimately make users "love" using the product to achieve their goal, instead of just "having to use" it. Engaging in UX design helps me escape that trap. In case you are also interested in the UX side of development, I thought I'd share an interesting site I came across: UX myths. In particular, I recommend reading myths 9, 10, 12, 13, 14, 15 and 21. Let me know if there are other UX resources you recommend… Comments about this post welcome at the original blog.

  • Bunny Inc. Season 2: Spice Up Your Applications

    - by kellsey.ruppel
    The quality and effectiveness of online services is strongly dependent on core business processes and applications. Nonetheless, user friendly composite applications are still a challenge for enterprises, especially if they are also requested to embed social technologies to empower customization and facilitate collaboration. You can operate like Hare Inc. and disappoint your customers, delivering inefficient services and wasting outside-in innovation opportunities, or you can operate like Bunny Inc., leveraging participatory services to improve connections between people, information and applications. And maybe you are ahead enough to adopt a public enterprise cloud to drive business through organic conversations and jump-start productivity with more-purposeful social networking and contextual enterprise collaboration. Don't miss this second episode of Social Bunnies Season 2 to learn how to increase the value of existing enterprise systems while augmenting employee productivity, business flexibility and organizational awareness. Still looking for more information on composite applications. We've got a ton of great resources for you to learn more!

  • Are there any specific workflows or design patterns that are commonly used to create large functional programming applications?

    - by Andrew
    I have been exploring Clojure for a while now, although I haven't used it on any nontrivial projects. Basically, I have just been getting comfortable with the syntax and some of the idioms. Coming from an OOP background, with Clojure being the first functional language that I have looked very much into, I'm naturally not as comfortable with the functional way of doing things. That said, are there any specific workflows or design patterns that are common with creating large functional applications? I'd really like to start using functional programming "for real", but I'm afraid that with my current lack of expertise, it would result in an epic fail. The "Gang of Four" is such a standard for OO programmers, but is there anything similar that is more directed at the functional paradigm? Most of the resources that I have found have great programming nuggets, but they don't step back to give a broader, more architectural look.

  • Independent projects as a student to show off abilities

    - by tufcat
    I'm an inexperienced student (having learned up to data structures and algorithms through various online resources) of computer science, and I'm hoping to get a job as a developer some time after I've gotten a few independent projects done. My question is, how should I choose which projects to work on? I've been looking around stackoverflow-- people usually say to pick whatever you're interested in, but I don't have enough experience to even know what specifically I'm interested in, and possibly more importantly, I don't know what some common beginner project types are. Essentially, I'm at the gap between course work (and the projects entailed in those classes) and real programming, and I don't quite know how to start. If any of you have any ideas, I'd really appreciate it.

  • Designing an API on top with Java RMI and Rest APIs

    - by user1303881
    I'm working on the backend of a java web application. We have a document repository (Fedora Commons specifically) where we house xml files. I want to abstract the API of the repository internally so that we aren't tightly coupled to one product. I'd also like to give the flexibility of connecting to to a repository via Java RMI or REST APIs. I was hoping to get advice or resources on how to implement something like this. My thought it that I'd have some abstract repository class that had methods like getRecord, updateRecord, and deleteRecord. In the constructor I would pass the URI for the repository and the API method and port. This would allow some flexibility in the future so that if the REST api became more practical, but allow the flexibility or using RMI which could (should?) have better performance. Am I over thinking this or am I on the right path?

  • New videos available #dax #ssas #powerpivot

    - by Marco Russo (SQLBI)
    The collaboration I and Alberto started with Project Botticelli is starting producing content. At this point we have three videos available: DAX in Action shows the power of DAX in PowerPivot solving common patterns not so easy or fast to solve in other languages DAX: Calculated Columns vs. Measures shows the difference between calculated columns and measures in DAX Introduction to DAX has a content corresponding to the title! The first two videos are freely available, the third one is longer and visible only to subscribers. The goal for this series of video is to reach advanced Excel users and BI developers that are new to DAX. If we should categorize this content, it’s a sort of level 200 session in a conference. I don’t expect readers of this blog to watch this video (if not for the sake of curiosity!) but if you have to explain this subject to anyone else and you have other priorities… well, you can add this post to the list of resources you provide for studying the subject!

  • Quantitfying a cost for a software project

    - by The Elite Gentleman
    Disclaimer: I didn't know exactly where to put this question. If you feel that this question is not suitable for Programmers @ StackExchange, feel free to migrate it. Background: Broadening my last question, there is a request for tender for a software system that's open and I have decided to take it on. I am a software developer & engineer by profession and, in this tender process, I have to put on the pricing for my bid. I have been provided a documentation consisting of functional and non-functional requirements only. I have to put a project manager's cap on and think of all aspects, e.g. cost for implementation for the project, resources needed, etc. My question is: Is there a project framework that I can follow that breaks the project cycle into steps and corresponding cost aspect or how would I go about best calculating/approximating the cost for the project?

  • Book (or resource) on Java bytecode

    - by Andrea
    I am looking for some resources on the JVM bytecode. Ideally I would for a short book; something more than a blog post but not a 800 pages tome. If it is relevant, I am a Scala developer, not a Java one, although I know Java just fine. I would like something that allowed me to read JVM bytecode and answer questions such as: Why does the bytecode has to know about high level construct such as classes? Are subtyping relations still visible in bytecode? How does type erasure work exactly? How do Oracle and Dalvik bytecode differ, and what consequences does this have for, say, developing Android apps with Scala? How does the JVM manage the stack, and why exactly this creates issues with tail call elimination? and so on.

  • watchdog/0 process using all my CPU suddenly

    - by jeffery_the_wind
    I have a fresh installation of Ubuntu 12.04, I have been running it for about a week. Suddenly today I noticed my computer freezes every 5 seconds. I restarted the computer and I still get this. I believe it is a process called watchdog/0 that is using all the resources. See the attached pictures. How can I stop this? I can barely use my computer like this. UPDATE Well I just did a cold reboot, (shutdown, unplug, and plug back in, and turn on) and it seems to have fixed it. After looking at the man page for watchdog, it seems that this process may stay on during a restart? so it is more like a soft restart? Why that happens I don't know.

  • SOA Suite 11g (11.1.1.3): Creating a single server domain with SOA Suite and Oracle Service Bus func

    - by Chris Tomkins
    One of the major benefits of the latest version of the Oracle SOA products, SOA Suite 11gR1 PS2 (11.1.1.3) and Oracle Service Bus 11gR1 (11.1.1.3), is that both products depend on the same version of WebLogic Server 11g (10.3.3) and so can be installed in the same domain. If you are a developer building artifacts for both but with a laptop/desktop with limited resources then this is particularly useful, as you can install a single server domain (by default you get a domain with an admin server and multiple managed servers) which incorporates both sets of functionality. The viewlet below shows you how to go about creating such a single server domain, using the configuration wizard. Just click the Play button from the viewlet menu to start it. Note: As you have added all this functionality into a single server, it will take a few minutes to start up. As this is my first foray into the world of viewlets I’d be interested in your opinion as to whether you have found this useful and any tips/techniques for improving any future viewlets I may create.

  • Handling & processing credit card payments

    - by Bob Jansen
    I'm working on program that charges customers on a pay as you go per month modal. This means that instead of the customers paying their invoices at the start of the month, they will have to pay at the end of the month. In order to secure the payments I want my customers credit card information stored so that they can be charged automatically at the end of the month. I do not have the resources, time, or risk to handle and store my customers credit card information on my servers and am looking for a third party solution. I'm a tad overwhelmed by all the different options and services that are out there and was wondering if anyone with experience have any recommendations and tips. I'm having difficulty finding services that allow me to to store my customers credit card information and charge them automatically. Most of them seem to offer an invoice styled approach.
