  • Is there a pattern or best practice for passing a reference type to multiple classes vs a static class?

    - by Dave
    My .NET application creates HTML files, and as such, the structure looks like variable myData BuildHomePage() variable graph = new BuildGraphPage(myData) variable table = BuildTablePage(myData) BuildGraphPage and BuildTablePage both require access data, the myData object. In the above example, I've passed the myData object to 2 constructors. This is what I'm doing now, in my current project. The myData object, and it's properties are all readonly. The problem is, the number of pages which will require this object has grown. In the real project, there are currently 4, but the new spec is to have about 20. Passing this object to the constructor of each new object and assigning it to a field is a little time consuming, but not a hardship! This poses the question whether it's better practice to continue as I have, or to refactor and create a new static class for myData which can be referenced from any where in my project. I guess my abilities to use Google are poor, because I did try and find an appropriate pattern as I am sure this type of design must be common place but my results returned nothing. Is there a pattern which is suited, or do best practices lean towards one implementation over another.

  • Examples of permission-based authorization systems in .Net?

    - by Rachel
    I'm trying to figure out how to do roles/permissions in our application, and I am wondering if anyone knows of a good place to get a list of different permission-based authorization systems (preferably with code samples) and perhaps a list of pros/cons for each method. I've seen examples using simple dictionaries, custom attributes, claims-based authorization, and custom frameworks, but I can't find a simple explanation of when to use one over another and what the pros/cons are to using each method. (I'm sure there's other ways than the ones I've listed....) I have never done anything complex with permissions/authorization before, so all of this seems a little overwhelming to me and I'm having trouble figuring out what what is useful information that I can use and what isn't. What I DO know is that this is for a Windows environment using C#/WPF and WCF services. Some permission checks are done on the WCF service and some on the client. Some are business rules, some are authorization checks, and others are UI-related (such as what forms a user can see). They can be very generic like boolean or numeric values, or they can be more complex such as a range of values or a list of database items to be checked/unchecked. Permissions can be set on the group-level, user-level, branch-level, or a custom level, so I do not want to use role-based authorization. Users can be in multiple groups, and users with the appropriate authorization are in charge of creating/maintaining these groups. It is not uncommon for new groups to be created, so they can't be hard-coded.

  • Hot fix published for TFS2010 upgrade issues

    - by jehan
    Microsoft has released a hot fix for the issues that are identified after the migration of TFS2005/TFS2008 servers to TFS2010. The issues are related to Merging and Labels: ·         Labels that were created before the upgrade are entirely empty.  Labels could be also have incorrect contents. ·         The merge wizard in Visual Studio does not display all valid merge targets for a given source path/branch. ·         During merging, merge candidates are shown for changes that were already merged prior to the upgrade. If you have not yet upgraded to TFS 2010, the hotfix is now available and is highly recommended to be applied before configuring your team project collections. Because this hotfix applies to the upgrade of version control content, it must be applied after TFS 2010 setup is complete, but before configuration is started.  At the end of the setup experience, the Success screen is shown indicating the completion of the installation.  Normally, users will continue on to the configuration part, but in this case, the user need to cancel the configuration part by un-checking the “Launch Team Foundation Server Configuration Tool” box, which will enable the Cancel button. After exiting setup, the hotfix executable can be run to update the upgrade steps. Once the hotfix is installed, the TFS Configuration Wizard will need to be re-launched from the Start Menu to complete the upgrade process.    The hotfix has been published on MSDN Code Gallery – you can find it here: http://code.msdn.microsoft.com/KB2135068   If you have upgraded to TFS2010 and facing any of the above issues, then checkout this KB for Resolution: http://support.microsoft.com/kb/2193796/en-us

  • How to ignore certain coding standard errors in PHP CodeSniffer

    - by Tom
    We have a PHP 5 web application and we're currently evaluating PHP CodeSniffer in order to decide whether forcing code standards improves code quality without causing too much of a headache. If it seems good we will add a SVN pre-commit hook to ensure all new files committed on the dev branch are free from coding standard smells. Is there a way to configure PHP codeSniffer to ignore a particular type of error? or get it to treat a certain error as a warning instead? Here an example to demonstrate the issue: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> </head> <body> <div> <?php echo getTabContent('Programming', 1, $numX, $numY); if (isset($msg)) { echo $msg; } ?> </div> </body> </html> And this is the output of PHP_CodeSniffer: > phpcs test.php -------------------------------------------------------------------------------- FOUND 2 ERROR(S) AND 1 WARNING(S) AFFECTING 3 LINE(S) -------------------------------------------------------------------------------- 1 | WARNING | Line exceeds 85 characters; contains 121 characters 9 | ERROR | Missing file doc comment 11 | ERROR | Line indented incorrectly; expected 0 spaces, found 4 -------------------------------------------------------------------------------- I have a issue with the "Line indented incorrectly" error. I guess it happens because I am mixing the PHP indentation with the HTML indentation. But this makes it more readable doesn't it? (taking into account that I don't have the resouces to move to a MVC framework right now). So I'd like to ignore it please.

  • Do you ever worry that you're more concerned with how something is built rather than what you are actually building?

    - by Rob Stevenson-Leggett
    As a programmer I have an inherent nagging annoyance at my tools, other peoples code, my code, the world in general. I always want to improve it. So I refactor, I stay on top of the latest techniques. I try and learn patterns, I try to use frameworks so as not to reinvent the wheel. I can write a tech spec that will blow your socks off with the amount of patterns I can squeeze in. However, lately I feel I actually know more about the tools I use than how to actually implement successful software. I feel like I'm lacking in the human factors skill set and I believe that to be a successful software engineer takes more than knowing the coolest framework. I think it needs some of the following skillsets too. Interaction design User experience Marketing I've got a bit of this that I've learned from people I've worked with and great projects I've worked on but I don't feel like I "own" these skills. Am I right? Should I be trying to develop these skills further, or should these be left to the people who do these for a career? How do you make sure you don't get too tied up in how you're doing something and make sure you "make your users awesome"? Does anyone know of good resources for learning these skills from a programming point of view?

  • Banco Espírito Santo Increases Sales Campaign Success Rate with Siebel CRM

    - by Tony Berk
    Banco Espírito Santo (BES), founded in 1869, is the second-largest private financial institution in Portugal with a 20.3% domestic market share, 2.1 million customers, and more than 700 in-country branches. It also has a strong international presence with operations in 23 countries and four continents. With strong growth in its major markets, BES needed a modern, cost-effective, scalable, and reliable customer relationship management (CRM) solution for its retail operations. The bank wanted to optimize client relationship management and integrate all customer touch points and service channels to improve the success of its sales and marketing initiatives. BES implemented the same CRM solution as many other leading banks: Oracle's Siebel CRM. With Siebel CRM 8.1 and other Oracle solutions, BES significantly increased sales of its new financial products across all channels by up to 25%, and it expects to increase annual revenue by up US$4 million annually. It also improved the success rate of bank branch sales, marketing, and lead generation campaigns by nearly 10%. “We are very happy with Oracle’s Siebel CRM applications. We already knew that this was the best solution available, but it has surpassed our best expectations,” said João Manaças, Customer Relationship Management Manager, Personal Marketing Department, Banco Espírito Santo.

    This seems to be a problem with pulseaudio. I was logged in over VNC on my phone and started playing a video this caused X to crash (as sometimes happens). I restarted and suddenly the sound doesn't work. I have a Intel HDA/Realtek ALC889 00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller alsamixer is detecting this just fine. PulseAudio doesn't detect this alsa device so is using auto_null as the default sink (logs below). When I properly kill PulseAudio (tell it not to auto-start) direct ALSA communication with the sound card works just fine. speaker-test, for example, works. So the hardware and ALSA layers are fine IMO. In the logs, it seems that the card might be "busy" but I really don't know how or why it would be now (and never before). Is there an ALSA lock file somewhere that it still there because of my crash? I just ran sudo fuser /dev/snd/* and saw this: oli@bert:~$ sudo fuser /dev/snd/* /dev/snd/controlC0: 1884 /dev/snd/pcmC0D0c: 1884m /dev/snd/timer: 1884 A look at the process list (ps aux | grep 1884) tells me process 1884 is arecord -c 1 -f S16_LE -r 8000 -t raw. No idea what this is or why it's running. When I try and kill arecord (as root), it just respawns and rebinds on the hardware. I'm in a very annoying situation where I don't know what is going on and don't know how to find out. I'm open to all suggestions to get this working again. Fire away. And here's what I get when I stop PA auto-loading, kill it and then start it with -vvvv. oli@bert:~$ pulseaudio -vvvvv I: main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted I: main.c: setrlimit(RLIMIT_RTPRIO, (9, 9)) failed: Operation not permitted D: core-rtclock.c: Timer slack is set to 50 us.

  • Roadmap for Thinktecture IdentityServer

    - by Your DisplayName here!
    I got asked today if I could publish a roadmap for thinktecture IdentityServer (idrsv in short). Well – I got a lot of feedback after B1 and one of the biggest points here was the data access layer. So I made two changes: I moved to configuration database access code to EF 4.1 code first. That makes it much easier to change the underlying database. So it is now just a matter of changing the connection string to use real SQL Server instead of SQL Compact. Important when you plan to do scale out. I included the ASP.NET Universal Providers in the download. This adds official support for SQL Azure, SQL Server and SQL Compact for the membership, roles and profile features. Unfortunately the Universal Provider use a different schema than the original ASP.NET providers (that sucks btw!) – so I made them optional. If you want to use them go to web.config and uncomment the new provider. Then there are some other small changes: The relying party registration entries now have added fields to add extra data that you want to couple with the RP. One use case could be to give the UI a hint how the login experience should look like per RP. This allows to have a different look and feel for different relying parties. I also included a small helper API that you can use to retrieve the RP record based on the incoming WS-Federation query string. WS-Federation single sign out is now conforming to the spec. I made certificate based endpoint identities for SSL endpoints optional. This caused some problems with configuration and versioning of existing clients. I hope I can release the RC in the next days. If there are no major issues, there will be RTM very soon!

  • Is unit testing development or testing?

    - by Rubio
    I had a discussion with a testing manager about the role of unit and integration testing. She requested that developers report what they have unit and integration tested and how. My perspective is that unit and integration testing are part of the development process, not the testing process. Beyond semantics what I mean is that unit and integration tests should not be included in the testing reports and systems testers should not be concerned about them. My reasoning is based on two things. Unit and integration tests are planned and performed against an interface and a contract, always. Regardless of whether you use formalized contracts you still test what e.g. a method is supposed to do, i.e. a contract. In integration testing you test the interface between two distinct modules. The interface and the contract determine when the test passes. But you always test a limited part of the whole system. Systems testing on the other hand is planned and performed against the system specifications. The spec determines when the test passes. I don't see any value in communicating the breadth and depth of unit and integration tests to the (systems) tester. Suppose I write a report that lists what kind of unit tests are performed on a particular business layer class. What is he/she supposed to take away from that? Judging what should and shouldn't be tested from that is a false conclusion because the system may still not function the way the specs require even though all unit and integration tests pass. This might seem like useless academic discussion but if you work in a strictly formal environment as I do, it's actually important in determining how we do things. Anyway, am I totally wrong? (Sorry for the long post.)

  • Identity Propagation for Web Service - 11g

    - by Prakash Yamuna
    I came across this post from Beimond on how to do identity propagation using OWSM.As I have mentioned in the past here, here and here - Beimond has a number of excellent posts on OWSM. However I found one part of his comment puzzling. I quote: "OWSM allows you to pass on the identity of the authenticated user to your OWSM protected web service ( thanks to OPSS ), this username can then be used by your service. This will work on one or between different WebLogic domains. Off course when you don't want to use OWSM you can always use Oracle Access Manager OAM which can do the same." The sentence in red highlights the issue i find puzzling. In fact I just discussed this particular topic recently here. So let me try and clarify on a few points: a) OAM is used for Web SSO. b) OWSM is used for securing Web Services. You cannot do identity propagation using OAM for Web Services. c) You use SAML to do identity propagation across Web Services. OAM also supports SAML - but that is the browser profile of SAML relevant in the context of Web SSO and is not related to the SAML Token Profile defined as part of the WS-Security spec.

  • Best method to organize/manage dependencies in the VCS within a large solution

    - by SnOrfus
    A simple scenario: 2 projects are in version control The application The test(s) A significant number of checkins are made to the application daily. CI builds and runs all of the automation nightly. In order to write and/or run tests you need to have built the application (to reference/load instrumented assemblies). Now, consider the application to be massive, such that building it is prohibitive in time (an entire day to compile). The obvious side effect here, is that once you've performed a build locally, it is immediately inconsistent with latest. For instance: If I were to sync with latest, and open up one of the test projects, it would not locally build until I built the application. This is the same when syncing to another branch/build/tag. So, in order to even start working, I need to wait a day to build the application locally, so that the assemblies could be loaded - and then those assemblies wouldn't be latest. How do you organize the repository or (ideally) your development environment such that you can continually develop tests against whatever the current build is, or a given specific build, while minimizing building the application as much as possible?

  • Does it matter the direction of a Huffman's tree child node?

    - by Omega
    So, I'm on my quest about creating a Java implementation of Huffman's algorithm for compressing/decompressing files (as you might know, ever since Why create a Huffman tree per character instead of a Node?) for a school assignment. I now have a better understanding of how is this thing supposed to work. Wikipedia has a great-looking algorithm here that seemed to make my life way easier. Taken from http://en.wikipedia.org/wiki/Huffman_coding: Create a leaf node for each symbol and add it to the priority queue. While there is more than one node in the queue: Remove the two nodes of highest priority (lowest probability) from the queue Create a new internal node with these two nodes as children and with probability equal to the sum of the two nodes' probabilities. Add the new node to the queue. The remaining node is the root node and the tree is complete. It looks simple and great. However, it left me wondering: when I "merge" two nodes (make them children of a new internal node), does it even matter what direction (left or right) will each node be afterwards? I still don't fully understand Huffman coding, and I'm not very sure if there is a criteria used to tell whether a node should go to the right or to the left. I assumed that, perhaps the highest-frequency node would go to the right, but I've seen some Huffman trees in the web that don't seem to follow such criteria. For instance, Wikipedia's example image http://upload.wikimedia.org/wikipedia/commons/thumb/8/82/Huffman_tree_2.svg/625px-Huffman_tree_2.svg.png seems to put the highest ones to the right. But other images like this one http://thalia.spec.gmu.edu/~pparis/classes/notes_101/img25.gif has them all to the left. However, they're never mixed up in the same image (some to the right and others to the left). So, does it matter? Why?

  • Java EE 7 JSR Submitted

    - by Tori Wieldt
    Java EE 7 has been filed as JSR 342 in the JCP program. This JSR (Java Specification Request) will develop Java EE 7, the next version of the Java Platform, Enterprise Edition. It is an "umbrella JSR" because the specification includes a collection of several other JSRs. The proposal suggests the addition of two new JSRs: Concurrency Utilities for Java EE (JSR-236) and JCache (JSR-107) as well as updates to JPA, JAX-RS, JSF, Servlets, EJB, JSP, EL, JMS, JAX-WS, CDI, Bean Validation, JSR-330, JSR-250, and Java Connector Architecture. There are also two new APIs under discussion: a Java Web Sockets API and a Java JSON API. These are the new JSRs that are currently up for ballot:• JSR 342: Java Platform, Enterprise Edition 7 Specification• JSR 340: Java Servlet 3.1 Specification• JSR 341: Expression Language 3.0• JSR 343: Java Message Service 2.0• JSR 344: JavaServer Faces 2.2All 5 JSRs are now up for Executive Committee voting with ballots closing on 14 March, and slated for inclusion in Java EE  7.  All of these JSRs are also open for Expert Group nominations. Any JCP member can nominate themself to serve on the Expert Groups for these JSRs. Details on how to become a JCP member are on jcp.org. The JCP gives you a chance to have your own work become an official component of the Java platform and to offer suggestions for improving and growing the technology. Either way, everyone in the Java community benefits from your participation.There's a nice discussion about Java EE 7 in this podcast with Java EE spec lead Robert Chinnici and more information in this blog post on the Aquarium. It's exciting to see so much activity currently underway.

  • How common is prototyping as the first stage of development?

    - by EpsilonVector
    I've been taking some software design courses in the past few semesters, and while I see the benefit in a lot of the formalism, I feel like it doesn't tell me anything about the program itself: You can't tell how the program is going to operate from the Use Case spec, even though it discusses what the program can do. You can't tell anything about the user experience from the requirements document, even though it can include quality requirements. Sequence diagrams are a good description of how the software works as the call stack, but are very limited, and give a highly partial view of the overall system. Class diagrams are great for describing how the system is built, but are utterly useless in helping you figure out what the software needs to be. Where in all this formalism is the bottom line: how the program looks, operates, and what experience it gives? Doesn't it make more sense to design off of that? Isn't it better to figure out how the program should work via a prototype and strive to implement it for real? I know that I'm probably suffering from being taught engineering by theoreticians, but I need to ask, do they do this in the industry? How do people figure out what the program actually is, not what it should conform to? Do people prototype a lot, or do they mostly use the formal tools like UML and I just didn't get the hang of using them yet?

  • Strange if-else branching behavior in a fragment shader

    - by Winged
    In my fragment shader I have passed an uniform int uLightType variable, which indicates what type of light is in usage right now. The problem is that if-else branching does not work correctly - the fragment shader performs instructions in every if statement block. if (uLightType == 1) { // Spotlight light type vec3 depthTextureCoord = vDepthPosition.xyz / vDepthPosition.w; shadowDepth = unpack(texture2D(uDepthMapSampler, depthTextureCoord.xy)); } else if (uLightType == 2) { // Omni-directional light type shadowDepth = unpack(textureCube(uDepthCubemapSampler, -lightVec)); } In the case when uLightType equals 1, unless I comment out the content of the second if block, it assigns an another value to shadowDepth. Also while uLightType equals 1, when I remove the second 'if' block and change == to != like in the sample code below, nothing happens (which means that uLightType really equals 1). if (uLightType != 1) { // Spotlight light type vec3 depthTextureCoord = vDepthPosition.xyz / vDepthPosition.w; shadowDepth = unpack(texture2D(uDepthMapSampler, depthTextureCoord.xy)); } Also, when I manually create an int variable (which is not an uniform) like this: var lightType = 1; and replace uLightType with it in the if-else branch, everything works fine, so I guess it have something to do with the fact that uLightType is the uniform.

  • 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!!

  • How common is prototyping as the first stage of development?

    - by EpsilonVector
    I've been taking some software design courses in the past few semesters, and while I see the benefit in a lot of the formalism, I still feel like it doesn't tell me anything about the program itself. You can't tell how the program is going to operate from the Use Case spec, even though it discusses what the program can do, and you can't tell anything about the user experience from the requirements document, even though it can include QA requirements. ...sequence diagrams are as good a description of how the software works as the call stack, in other words- very limited, highly partial view of the overall system, and a class diagram is great for describing how the system is built, but is utterly useless in helping you figure out what the software needs to be. Where in all this formalism is the bottom line- how the program looks, operates, and what experience it gives? Doesn't it make more sense to design off of that? Isn't it better to figure out how the program should work via a prototype and strive to implement it for real? I know that I'm probably suffering from being taught engineering by theoreticians, but I got to ask, do they do this in the industry? How do people figure out what the program actually is, not what it should conform to? Do people prototype a lot? ...or do they mostly use the formal tools like UML and I just didn't get the hang of using them yet?

  • Component-wise GLSL vector branching

    - by Gustavo Maciel
    I'm aware that it usually is a BAD idea to operate separately on GLSL vec's components separately. For example: //use instrinsic functions, they do the calculation on 4 components at a time. float dot = v1.x*v2.x + v1.y * v2.y + v1.z * v2.z; //NEVER float dot = dot(v1, v2); //YES //Multiply one by one is not good too, since the ALU can do the 4 components at a time too. vec3 mul = vec3(v1.x * v2.x, v1.y * v2.y, v1.z * v2.z); //NEVER vec3 mul = v1 * v2; I've been struggling thinking, are there equivalent operations for branching? For example: vec4 Overlay(vec4 v1, vec4 v2, vec4 opacity) { bvec4 less = lessThan(v1, vec4(0.5)); vec4 blend; for(int i = 0; i < 4; ++i) { if(less[i]) blend[i] = 2.0 * v1[i]*v2[i]; else blend[i] = 1.0 - 2.0 * (1.0 - v1[i])*(1.0 - v2[i]); } return v1 + (blend-v1)*opacity; } This is a Overlay operator that works component wise. I'm not sure if this is the best way to do it, since I'm afraid these for and if can be a bottleneck later. Tl;dr, Can I branch component wise? If yes, how can I optimize that Overlay function with it?

  • Is "as long as it works" the norm?

    - by q303
    Hi, My last shop did not have a process. Agile essentially meant they did not have a plan at all about how to develop or manage their projects. It meant "hey, here's a ton of work. Go do it in two weeks. We're fast paced and agile." They released stuff that they knew had problems. They didn't care how things were written. There were no code reviews--despite there being several developers. They released software they knew to be buggy. At my previous job, people had the attitude as long as it works, it's fine. When I asked for a rewrite of some code I had written while we were essentially exploring the spec, they denied it. I wanted to rewrite the code because code was repeated in multiple places, there was no encapsulation and it took people a long time to make changes to it. So essentially, my impression is this: programming boils down to the following: Reading some book about the latest tool/technology Throwing code together based on this, avoiding writing any individual code because the company doesn't want to "maintain custom code" Showing it and moving on to the next thing, "as long as it works." I've always told myself that next job I'm going to get a better shop. It never happens. If this is it, then I feel stuck. The technologies always change; if the only professional development here is reading the latest MS Press technology book, then what have you built in 10 years but a superficial knowledge of various technologies? I'm concerned about: Best way to have professional standards How to develop meaningful knowledge and experience in this situation
