  • AngularJS: structuring a web application with multiple ng-apps

    - by mg1075
    The blogosphere has a number of articles on the topic of AngularJS app structuring guidelines such as these (and others): http://www.johnpapa.net/angular-app-structuring-guidelines/ http://codingsmackdown.tv/blog/2013/04/19/angularjs-modules-for-great-justice/ http://danorlando.com/angularjs-architecture-understanding-modules/ http://henriquat.re/modularizing-angularjs/modularizing-angular-applications/modularizing-angular-applications.html However, one scenario I have yet to come across for guidelines and best practices is the case where you have a large web application containing multiple "mini-spa" apps, and the mini-spa apps all share a certain amount of code. I am not referring to the case of trying to have multiple ng-app declarations on the same page; rather, I mean different sections of a large site that have their own, unique ng-app declaration. As Scott Allen writes in his OdeToCode blog: One scenario I haven't found addressed very well is the scenario where multiple apps exist in the same greater web application and require some shared code on the client. Are there any recommended approaches to take, pitfalls to avoid, or good sample structures of this scenario that you can point to?

  • 7-Eleven Improves the Digital Guest Experience With 10-Minute Application Provisioning

    - by MichaelM-Oracle
    By Vishal Mehra - Director, Cloud Computing, Oracle Consulting Making the Cloud Journey Matter There’s much more to cloud computing than cutting costs and closing data centers. In fact, cloud computing is fast becoming the engine for innovation and productivity in the digital age. Oracle Consulting Services contributes to our customers’ cloud journey by accelerating application provisioning and rapidly deploying enterprise solutions. By blending flexibility with standardization, our Middleware as a Service (MWaaS) offering is ensuring the success of many cloud initiatives. 10-Minute Application Provisioning Times at 7-Eleven As a case in point, 7-Eleven recently highlighted the scope, scale, and results of a cloud-powered environment. The world’s largest convenience store chain is rolling out a Digital Guest Experience (DGE) program across 8,500 stores in the U.S. and Canada. Everyday, 7-Eleven connects with tens of millions of customers through point-of-sale terminals, web sites, and mobile apps. Promoting customer loyalty, targeting promotions, downloading digital coupons, and accepting digital payments are all part of the roadmap for a comprehensive and rewarding customer experience. And what about the time required for deploying successive versions of this mission-critical solution? Ron Clanton, 7-Eleven's DGE Program Manager, Information Technology reported at Oracle Open World, " We are now able to provision new environments in less than 10 minutes. This includes the complete SOA Suite on Exalogic, and Enterprise Manager managing both the SOA Suite, Exalogic, and our Exadata databases ." OCS understands the complex nature of innovative solutions and has processes and expertise to help clients like 7-Eleven rapidly develop technology that enhances the customer experience with little more than the click of a button. OCS understood that the 7-Eleven roadmap required careful planning, agile development, and a cloud-capable environment to move fast and perform at enterprise scale. Business Agility Today’s business-savvy technology leaders face competing priorities as they confront the digital disruptions of the mobile revolution and next-generation enterprise applications. To support an innovation agenda, IT is required to balance competing priorities between development and operations groups. Standardization and consolidation of computing resources are the keys to success. With our operational and technical expertise promoting business agility, Oracle Consulting's deep Middleware as a Service experience can make a significant difference to our clients by empowering enterprise IT organizations with the computing environment they seek to keep up with the pace of change that digitally driven business units expect. Depending on the needs of the organization, this environment runs within a private, public, or hybrid cloud infrastructure. Through on-demand access to a shared pool of configurable computing resources, IT delivers the standard tools and methods for developing, integrating, deploying, and scaling next-generation applications. Gold profiles of predefined configurations eliminate the version mismatches among databases, application servers, and SOA suite components, delivered both by Oracle and other enterprise ISVs. These computing resources are well defined in business terms, enabling users to select what they need from a service catalog. Striking the Balance between Development and Operations As a result, development groups have the flexibility to choose among a menu of available services with descriptions of standard business functions, service level guarantees, and costs. Faced with the consumerization of enterprise IT, they can deliver the innovative customer experiences that seamlessly integrate with underlying enterprise applications and services. This cloud-powered development and testing environment accelerates release cycles to ensure agile development and rapid deployments. At the same time, the operations group is relying on certified stacks and frameworks, tuned to predefined environments and patterns. Operators can maintain a high level of security, and continue best practices for applications/systems monitoring and management. Moreover, faced with the challenges of delivering on service level agreements (SLAs) with the business units, operators can ensure performance, scalability, and reliability of the infrastructure. The elasticity of a cloud-computing environment – the ability to rapidly add virtual machines and storage in response to computing demands -- makes a difference for hardware utilization and efficiency. Contending with Continuous Change What does it take to succeed on the promise of the cloud? As the engine for innovation and productivity in the digital age, IT must face not only the technical transformations but also the organizational challenges of the cloud. Standardizing key technologies, resources, and services through cloud computing is only one part of the cloud journey. Managing relationships among multiple department and projects over time – developing the management, governance, and monitoring capabilities within IT – is an often unmentioned but all too important second part. In fact, IT must have the organizational agility to contend with continuous change. This is where a skilled consulting services partner can play a pivotal role as a trusted advisor in the successful adoption of cloud solutions. With a lifecycle services approach to delivering innovative business solutions, Oracle Consulting Services has expertise and a portfolio of services to help enterprise customers succeed on their cloud journeys as well as other converging mega trends .

  • How to emulate Mode 13h in a modern 3D renderer?

    - by David Gouveia
    I was indulging in nostalgia and remembered the first game I created, which used Mode 13h. This mode was really simple to work with, since it was essentially just an array of bytes with an element for each pixel on the screen (using an indexed color scheme). So I thought it might be fun to create something nowadays under these restrictions, but on modern hardware. The API could be as simple as: public class Mode13h { public byte[] VideoMemory = new byte[320 * 200]; public Color[] Palette = new Color[256]; } Now I'm wondering what would be the best way to get this data on the screen, using something like XNA / DirectX / OpenGL. The only solution I could think of was to create a texture with the same size as the VideoMemory array, write the contents of VideoMemory to it every frame, then render that texture in a full screen quad with the correct aspect ratio and using point texture filtering for that retro look. Is there a better way?

  • Booting briefly shows CLI login and then black

    - by lepusfelix
    When I boot to Ubuntu on my dualboot system, it appears to boot normally, up to the point when I would normally expect to see the lightDM graphical login screen. However, I see a CLI login screen, which I assume is tty1. Before I get a chance to actually login to it, though, it drops to a black screen with a flashing cursor. Pressing ctrl+alt+f1 does nothing. When I hit the power button on the laptop, I see the usual scrolling text as Ubuntu shuts down. I know that this is related to me having installed the proprietary ATI drivers for the video card. Purging the drivers gave me back a GUI, but unfortunately no working desktop environment, and switching to the mesa drivers returned me to the black screen issue. The only way I can get a stable working CLI is through booting to advanced options and choosing a root shell prompt, as even the failsafe X session doesn't function for me.

  • Any enlightenment for understanding Object Oriented Programming? [closed]

    - by ????
    I studied computer science near the end of 1980s, and wasn't taught OOP that formally. With Pascal or C, when I understand the top-down design of functions, and the idea of black box, then everything just seem to make sense, as if there is a "oh I get it!" -- some kind of totally getting it and enlightenment feeling. But with OOP, all I know was the mechanics: the class, instance, method, inheritance, polymorphism, encapsulation. It was like, I knew all the "this is how it is", but never had the feeling of "I totally get it", the enlightened feeling. Would somebody be able to describe it, or point to a chapter in some book or paper which talks about OOP so that the reader can feel: "I totally get it!" on OOP?

  • Is the carriage-return char considered obsolete

    - by Evan Plaice
    I wrote an open source library that parses structured data but intentionally left out carriage-return detection because I don't see the point. It adds additional complexity and overhead for little/no benefit. To my surprise, a user submitted a bug where the parser wasn't working and I discovered the cause of the issue was that the data used CR line endings as opposed to LF or CRLF. Hasn't OSX been using LF style line-endings since switching over to a unix-based platform? I know there are applications like Notepad++ where line endings can be changed to use CR explicitly but I don't see why anybody would want to. Is it safe to exclude support for the statistically insignificant percentage of users who decide (for whatever reason) to the old Mac OS style line-endings?

  • 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!

  • Keeping rotation between two objects

    - by user99
    In my XNA game I have two objects that collide. When the first object collides with the other it is able to latch on to it and move it about the world. I am having a problem with the math here (Math isn't my strong point). I currently have the second object latch on to the first and move around with it, but I cannot get it to keep it's original direction. So, if the object is facing up it should keep this direction relative to how it is being rotated with the original item. Any tips on how I could best to achieve this?

  • Restoring windows path on Windows 7

    - by Renso
    Issue:You changed the windows path and made a mistake and now want to reset it.Solution:In short, you can't. If you restore to the system default, you will loose any paths that were appended when you or the manufacturer installed software and drivers. Each time you install some sort of software or driver, MS Office, Turbotax, etc., it creates/appends to the path so that it points to it's start-up program.Too late now, but you should create a restore point BEFORE you touch the windows path if you are not sure what you are doing:http://www.sevenforums.com/tutorials/700-system-restore.html http://www.sevenforums.com/tutorials/2083-system-repair-disc-create.html At a minimum you need the following:%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\AT worst you can reset it to the above, and go through each application as you use them and run into problems to fix the path. The REPAIR option when you select to change/uninstall a program can help with that.

  • How customers view and interact with a company

    The Harvard Business Review article written by Rayport and Jaworski is aptly titled “Best Face Forward” because it sheds light on how customers view and interact with a company. In the past most business interaction between customers was performed in a face to face meeting where one party would present an item for sale and then the other would decide whether to purchase the item. In addition, if there was a problem with a purchased item then they would bring the item back to the person who sold the item for resolution. One of my earliest examples of witnessing this was when I was around 6 or 7 years old and I was allowed to spend the summer in Tennessee with my Grandparents. My Grandfather had just written a book about the local history of his town and was selling them to his friends and local bookstores. I still remember he offered to pay me a small commission for every book I helped him sell because I was carrying the books around for him. Every sale he made was face to face with his customers which allowed him to share his excitement for the book with everyone. In today’s modern world there is less and less human interaction as the use of computers and other technologies allow us to communicate within seconds even though both parties may be across the globe or just next door. That being said, customers view a company through multiple access points called faces that represent the ability to interact without actually seeing a human face. As a software engineer this is a good and a bad thing because direct human interaction and technology based interaction have both good and bad attributes based on the customer. How organizations coordinate business and IT functions, to provide quality service varies based on each individual business and the goals and directives put in place by its management. According to Rayport and Jaworski, the type of interaction used through a particular access point may lend itself to be people-dominate, machine-dominate, or a combination of both. The method by which a company communicates information through an access point is a strategic choice that relates costs and customer outcomes. To simplify this, the choice is based on what can give the customer the best experience interacting with the company when the cost of the interaction is also a factor. I personally see examples of this every day at work. The company website is machine-dominate with people updating and maintaining information, our groups department is people dominate because most of the customer interaction is done at the customers location and is backed up by machine based data sources, and our sales/member service department is a hybrid because employees work in tandem with machines in order for them to assist customers with signing up or any other issue they may have. The positive and negative aspects of human and machine interfaces are a key aspect in deciding which interface to use when allowing customers to access a company or a combination of the two. Rayport and Jaworski also used MIT professor Erik Brynjolfsson preliminary catalog of human and machine strengths. He stated that humans outperform machines in judgment, pattern recognition, exception processing, insight, and creativity. I have found this to be true based on the example of how sales and member service reps at my company handle a multitude of questions and various situations with a lot of unknown variables. A machine interface could never effectively be able to handle these scenarios because there are too many variables to consider and would not have the built-in logic to process each customer’s claims and needs. In addition, he also stated that machines outperform humans in collecting, storing, transmitting and routine processing. An example of this would be my employer’s website. Customers can simply go online and purchase a product without even talking to a sales or member services representative. The information is then stored in a database so that the customer can always go back and review there order, and access their selected services. A human, no matter how smart they are would never be able to keep track of hundreds of thousands of customers let alone know what they purchased or how much they paid. In today’s technology driven economy every company must offer their customers multiple methods of accessibly in order to survive. The more of an opportunity a company has to create a positive experience for their customers, in my opinion, they more likely the customer will return to that company again. I have noticed this with my personal shopping habits and experiences. References Rayport, J., & Jaworski, B. (2004). Best Face Forward. Harvard Business Review, 82(12), 47-58.

  • How to estimate tasks in scrum?

    - by Arian
    Let's say we have a backlog of User Stories, each with an estimated number of Story Points, and now we're doing the Sprint Planning. Now, the Stories should be broken down into tasks and many Scrum resources suggest that each task should be estimated in person-hours. Since all questions have been discussed by the team at this point, estimating a task should not take longer than a minute. However, since a task should not be longer than a day, assuming a three week sprint with 8 developers means 120 tasks, and taking two hours only for estimations seems to be a bit much to me. I know that experienced teams can skip or short-cut task estimations, but let's say we're not at that stage yet. In your experience, how many tasks are there in a sprint* and how long should it take to estimate all of them? (Estimating only half of them doesn't make much sense, does it?) (*) I know that depends on sprint length and team size, so let's assume 8 developers and three weeks.

  • Declaring interface in the same file as the base class, is it a good practice?

    - by Louis Rhys
    To be interchangable and testable, normally services with logic needs to have interface, e.g. public class FooService: IFooService { ... } Design-wise, I agree with this, but one of the things that bothers me with this approach is that for one service you will need to declare two things (the class and the interface), and in our team, normally two files (one for the class and one for the interface). Another discomfort is the difficulty in navigation because using "Go to definition" in IDE (VS2010) will point to the interface (since other classes refer to the interface), not the actual class. I was thinking that writing IFooService in the same file as FooService will reduce the above weirdness. After all, IFooService and FooService are very related. Is this a good practice? Is there a good reason that IFooService must be located in its own file?

  • This not having job, is driving me nuts!

    - by Ratman21
    I had two jobs lined up (temporary but, hey they pay), one of which was in IT. A very low paying IT job for only 30 hours a week and only 3 weeks. At a large high tech company and a government (a not in my field job) temporary, paying a bit more, for little longer and for up to 40 hours a week. I was going to happily work my little self raged for the next 3 weeks. Guess what, the IT job fell thru and I now feel so let down. This I felt was my chance to get back in to IT, even if it was only for few weeks and maybe get note-us as hard working IT guy. I still have the other job but, let me add that there is no chance that it will turn in to something longer (I have been told that point blank). As I said this is nuts.

  • AndEngine Sprite position

    - by Kirill Kulakov
    I had noticed the AndEngine a few days ago, and I tried to create basic game with a few Sprites.Sure, the engine makes the development process much more easier.However I found the sprite lacking a major functionally: Whenever there is a need to refer to the position of an Sprite the engine manipulates the position based on the top-left corner of sprite,this is not the best thing because there is a need to subtract/add the width/height to its position in order to refer to its center.However when we refer to he scale of the Sprite it scaled according to its center point (which is great) I find it very confusing to refer to its position each time differently.I solved that by extending the Sprite class and implementing my methods of setCenter and getCenter, I guess that not the best way to do so. Do you have any suggestion?

  • Why should I use Bower? [closed]

    - by Wil
    I can fully appreciate the benefits of a package manager like Python PIP, Node npm, or Ruby Gems since they're doing much more than adding files to your applications path. Maybe I'm missing the point, or I'm being obtuse, but here are the negatives I can see: Separate step when building a project Separate dependency to install via another package manager (yo dawg) More clutter in the projects root with bower.json and / or .bowerrc Reliance on the registry being up to date, correct, and available Some imports / references to things like images won't work The positives I can see are these: I don't have to download the dependencies manually Optionally install packages as part of scaffolding based on user prompts or the like I'd really like to know of any benefits I'm unaware of, and I should say I'm not trying to be provocative I genuinely want to know.

  • Elantech trackpad being identified as a logitech wheel mouse.

    - by Nathan Cox
    I recently purchased a Samsung RF510 laptop computer, which I absolutely love. However, upon installing Ubuntu 10.10 onto it I couldn't get the trackpad to function properly. It worked as a basic mouse (point and click) but had no functionality for edge scrolling or any of the multitouch settings the trackpad is capable of. After doing a lot of research I discovered the reason is a known issue where the Ubuntu kernel will improperly detect an Elantech trackpad as a logitech PS/2 wheel mouse, and as such will gain none of the functionality that seems to be coded for synaptics trackpads. The question I have is: does anyone know a way to get this working properly? This is my first time trying to run Ubuntu on a laptop (actually, it's my first laptop in the last 12 years) and I'm finding the experience to be intolerable without the basic scrolling/zooming/etc I've been used to using for as long as I can remember.

    This question seems to be asked previously on this site but the audience targeted are different. I am an Engineering student who knows Python, C and familiar with Java(learning now; good at fundamentals) & HTML. Now, I want to develop facebook & Android apps. I went through their respective documentations but couldn't really understand and thought to search for beginner books but they have been written from too basic. (There is an beginner's android book for from APress for people who have no idea of programming). My problem is, I am unable to find the right book to learn. Either they are for beginners or for experts... For guys like me, can anyone point out a good book?

  • Windows Phone 7 Design Template

    Expression Blend is a wonderful design environment for WP7 (Windows Phone 7) but for quickly visualizing a concept nothing beats Illustrator! I am excited about WP7 and decided that having a solid .ai template would prove invaluable. Some of the details of the WP7 UI Design and Interaction Guide are a bit fuzzy (literally) but I was able to generate some useful layout guides, character styles, and symbols. While the template does not cover every aspect of the guide I think it is a good launching point; if you find it useful and extend it please share your updates (I created the template in CS4, if you have problems in earlier versions let me know).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 USB drives goes after system hard drives

    - by raihanchy
    I am using Ubuntu 12.04 LTS. My hard drives usually comes as: sda, with 'sudo blkid' and if I plug-in any USB drive, they comes as: sdb, sdc etc; after sda. That's fine!!! But problem arises after I restart my laptop with connecting those USB drives. They alter and comes first and hard drive goes to the end, like: 'sudo blkid' shows, sda, sdb for USB drives and sdc for hard drives. It's making problem to mount with /etc/fstab. I couldn't find any solutions for this. I would like to have any USB drives after my system hard drives, as in Windows. Please, help me at this point. Thanking you. Raihan

  • 302 Redirect causes garbage at end of Wordpress link in Facebook

    - by Joao
    When I try to link my Wordpress blog to Facebook, the url doesn't resolve properly. There's garbage appended at the end and Facebook is not able to retrieve information from the site. Happens in every page, post or main entry. Here's what happens: http://clarissarezende.com.br/ shows up in Facebook as http://clarissarezende.com.br/UPLcS/ (when copy/paste the link) and no information about the site shows up in FB. I'm using Wordpress 3.3.1 with ProPhoto 4. Recently I moved the DNS entry on my ISP. The blog is hosted at clarissarezende.com.br/public_html/blog2 and before the DNS would point to public_html and then I changed it to public_html/blog2. Note that I did not move any Wordpress files. Made the (I think) necessary changes all over Facebook, but still no dice... Any ideas on what can be happening?

  • Why were annotations introduced in Spring and Hibernate?

    - by Chandrashekhar
    I would like to know why were annotations introduced in Spring and Hibernate? For earlier versions of both the frameworks book authors were saying that if we keep configuration in xml files then it will be easier to maintain (due to decoupling) and just by changing the xml file we can re-configure the application. If we use annotations in our project and in future we want to re-configure application then again we have to compile and build the project. So why were these annotations introduced in these frameworks? From my point of view annotations make the apps dependent on certain framework. Isn't it true?

  • Method chaining vs encapsulation

    - by Oak
    There is the classic OOP problem of method chaining vs "single-access-point" methods: main.getA().getB().getC().transmogrify(x, y) vs main.getA().transmogrifyMyC(x, y) The first seems to have the advantage that each class is only responsible for a smaller set of operations, and makes everything a lot more modular - adding a method to C doesn't require any effort in A, B or C to expose it. The downside, of course, is weaker encapsulation, which the second code solves. Now A has control of every method that passes through it, and can delegate it to its fields if it wants to. I realize there's no single solution and it of course depends on context, but I would really like to hear some input about other important differences between the two styles, and under what circumstances should I prefer either of them - because right now, when I try to design some code, I feel like I'm just not using the arguments to decide one way or the other.

  • Complete Guide/Tutorials on LWJGL?

    - by user43353
    Dont get me wrong, I finished these tutorials on http://lwjgl.org/wiki/index.php?title=Main_Page. I finished The Basics section, OpenGL 3.2 and newer section, and I looked at the Example Code section. They were great tutorials, and I have looked at the external tutorials as well. I don't know where to go from here, and OpenGL is not my strong point. Some one suggested Learning Modern 3D Graphics Programming, and I didnt learn much. I looked at the port to LWJGL, but the book was on C and I couldn't really understand what the OpenGL meant. I am trying to learn 2D gaming, not 3D. Maybe later. Is there any tutorials that aren't C/C++ heavy and teach you 2D OpenGL?
