  • Examples and Best Practices for Seeding Defects?

    - by MathAttack
    Defect Seeding seems to be one of the few ways a development organization can tell how thorough an independent testing group is. I'm a fan of using metrics to help counter overconfidence biases, and drive discussions around facts. With that said, I haven't seen Seeding Defects used in practice. Are there best practices above and beyond what McConnell explained? Are there public examples where this has been done? In the absence of the above, any thoughts on why it hasn't been done more? Thanks in advance!

  • Development on Terminal or IDE [on hold]

    - by Taylor Flores
    I've been using nano, make, gcc, and gdb for 6 months now and I've found it much easier than using VS or Codeblocks. But I'm wondering now: Is development on a terminal more/less efficient that using an IDE? In what situations is one preferred more sensible than the other? I'm not asking about opinions, I want to know if there's specific reasons to use one over the other. From what I can gather: terminals can be used on environments where a GUI is not available terminal projects can be created and configured more quickly IDEs contain better syntax highlighters (ie identity highlighters) This question is C biased, but I think it's relevant to other languages as well.

  • What is the best way to diagrammatically represent a system threading architecture?

    - by thegreendroid
    I am yet to find the perfect way to diagrammatically represent the overall threading architecture for a system (using UML or otherwise). I am after a diagramming technique that would show all the threads in a given system and how they interact with each other. There are a few similar questions - Drawing Thread Interaction, UML Diagrams of Multithreaded Applications and Intuitive UML Approach to Depict Threads but they don't fully answer my question. What are some of the techniques that you've found useful to depict the overall threading architecture for a system?

  • How to use TFS as a query tracking system?

    - by deostroll
    We already use tfs for managing defects in code etc, etc. We additionally need a way to "understand the domain & requirements of the products". Normally, without tfs we exchange emails with the consultants and have the questions/queries answered. If it is a feature implementation we sometimes "find" conflicts in the implementation itself. And when that happens the userstory is modified and the enhancement/bug as per that is raised in TFS. Sometimes it is critical we come back to decisions we made or questions we wanted answers to. Hence we need to be able to track how that "requirement idea" or that "query in concern" evolved. Hence how is it that we can use TFS to track all of this? Do we raise an "issue" item for this? Or do we raise a "bug" item? The main things we'd ideally look in a query tracking system are as follows: Area: Can be a module, submodule, domain. Sometimes this may be "General" - to address domain related stuff, or, event more granular to address modules, sub-modules. Take the case for the latter, if we were tracking this in excel sheets, we'd just write module1,submodule2; i.e. in a comma separated fashion. The things I would like here is to be able search for all queries relating to submodule2 sometime in the future. Responses: This is a record of conversations between the consultant and any other stakeholder. For a simple case, it would just be paragraphs. Each para would start with a name and date enclosed in brackets and the response following that...each para would be like a thread - much like a forum thread Action taken: We'd want to know how the query was closed, what was the input given, what were the changes that took place because of that, etc etc. These are fields I think I would need in such a system apart from some obvious ones like status, address to, resovled by, etc. I am open for any other fields which are sort of important. To summarise my question: how can we manage "queries" in the system? Where should we ideally store data pertaining to those three fields I have mentioned above (for e.g. is it wise to store responses in the history tag assuming we are opening a bug for the query)?

  • What makes for a good JIRA workflow with a software development team?

    - by Hari Seldon
    I am migrating my team from a snarl of poorly managed excel documents, individual checklists, and personal emails to manage our application issues and development tasks to a new JIRA project. My team and I are new to JIRA (and issue tracking software in general). My team is skeptical of the transition at best, so I am also trying not to scare them off by introducing something overly complex at the start. I understand one of JIRA's strengths to be the customized workflows that can be created for a project. I've looked over the JIRA documentation and a number of tutorials, and am comfortable with the how in creating workflows, but I need some contextual What to go along with it. What makes a particular workflow work well? What does a poorly designed workflow look like? What are the benefits/drawbacks of a strict workflow with very specific states and transitions to a looser workflow, with fewer, broader defined states and transitions

  • Software development project inception phase

    - by john ryan
    Currently our team develops Web Applications and now we are going to Windows Forms applications. I have created the inception phase for our Windows Forms project structure. eg: ApplicationSolution --> Security Project(Login Authentication) a. Users will be registered with different applications in our application database. eg: ProjectApplicationId|ProjectName | UserId 1 |ProjectApplication1| user 2 |ProjectApplication2| user b. Execute Application (Start) c. On Security dialog, application automatically get the userid of the user and see all the application it is registered using System.Security.Principal.WindowsIdentity.GetCurrent() eg: Prototype Welcome User! Please Choose Appliations you are registered on below: ProjectApplication1 <--this will be a dropdown ProjectApplication2 Password: [*********************] [Access Application Button] d. User selects the application with its password e. If the password is incorrect (application.exit()) else execute Selected Application eg: ProjectApplication1 is selected then execute ProjectApplication1 --> ProjectApplication1 --> ProjectApplication2 --> Many to come ++ if ProjectApplications has been closed then restart security Application. My questions on this use case: Is my use case possible? Can you give me any recommendations ? Currently we use setup and deployment to create installer in each Windows Forms application.

  • Serialized values or separate table, which is more efficient?

    - by Aravind
    I have a Rails model email_condition_string with a word column in it. Now I have another model called request_creation_email_config with the following columns admin_filter_group:references vendor_service:references email_condition_string:references email_condition_string has many request_creation_email_config and request_creation_email_config belongs to email_condition_string. Instead of this model a colleague of mine is suggesting that strong the word inside the same model as comma separated values is efficient than storing as a separate model. Is that alright?

  • using a wiki for requirements

    - by apollodude217
    Hi, I'm looking into ways of improving requirements management. Currently, we have a Word document published on a Web site. Unfortunately, we cannot (to my knowledge) look at changes from one revision to the next. I would greatly prefer to be able to do so, much like with a wiki or VCS (or both, like the wiki's on bitbucket!). Also, each document describes changes devs are expected to meet by a given deadline. There is no collection of accumulated app features documented anywhere, so it's sometimes hard to distinguish between a bug and a (poorly-designed) feature when trying to make quick fixes to legacy apps. So I had an idea I wanted to get feedback on. What about: Using a wiki so that we can track who changed what when (mostly to even see if any edits were made since the last time one looked). Having one, say, wiki page per product rather than one per deadline, keeping up with all features of the product rather than the changes that should be implemented. This way, I can look at a particular revision of the page to see what the app should do at a given point in time, and I can look at changes to the page since the last release for the requirements to be implemented by the next deadline. Waddayathink?

  • Convincing my coworkers to use Hudson CI

    - by in0de
    Im really aware of some benefits of using Hudson as CI server. But, im facing the problem to convince my coworkers to install and use it. To put some context, we are developing two different products (one is an enterprise search engine based on Apache Solr) and several enterprise search projects. We are facing a lot of versioning issues and i think Hudson will solve this problems. They argued about its productivity and learning curve What Hudson's benefits would you spotlight?

  • .aspx websites: Is it built using web forms?

    - by Lazeera
    I visit many website which I think is built using ASP.NET web forms because of the extension (.aspx). When I view source of these website I see at least one or two something like: <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"> or wvcD4NCjxwPtin2YTZh9iv2YrYqSDYp9mE2KvYp9mG2YrYqSDZh9mKINit2..... However, yesterday I visited two sites on is the 'ASP.NET forums - http://forums.asp.net' and the other is 'POF'. The extension of these sites is still (.aspx) but when I view the source of these site I could not find any <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"> nor wvcD4NCjxwPtin2YTZh9iv2YrYqSDYp9mE2KvYp9mG2YrYqSDZh9mKINit2..... Now, I would like to know how those sites use ASP.NET Web Forms and their final HTML output is still clean?

  • Is Haskell's type system an obstacle to understanding functional programming?

    - by Eric Wilson
    I'm studying Haskell for the purpose of understanding functional programming, with the expectation that I'll apply the insight that I gain in other languages (Groovy, Python, JavaScript mainly.) I choose Haskell because I had the impression that it is very purely functional, and wouldn't allow for any reliance on state. I did not choose to learn Haskell because I was interested in navigating an extremely rigid type system. My question is this: Is a strong type system a necessary by-product of an extremely pure functional language, or is this an unrelated design choice particular to Haskell? If it is the latter, I'm curious what would be the most purely functional language that is dynamically typed. I'm not particularly opposed to strong typing, it has its place, but I'm having a hard time seeing how it benefits me in this educational endeavor.

  • Strategies for Indexing Custom Fields in RavenDB

    - by Adrian Thompson Phillips
    In the relational database world, if I was developing a CRM system and wanted to have the user add their own custom fields that are searchable, I could have tables that store the name of the new column, the data type and the value, etc. (which would be less inefficient to index) or I could use the less elegant (but more searchable) solution that software like Dynamics and SharePoint use, whereas I create a load of columns on my aggregate root called CustomInt1, CustomInt2, etc. (which looks dirty and has a limit of how many custom fields a user can have, but has indexing advantages). But my questions is this, in NoSQL databases, what would be the best way of achieving the same thing? My priority would be for searchability. So what would be the best way to store this data? If I used a predefined set of properties (i.e. CustomData1, CustomData2, etc.), because these are all stored as JSON (i.e. strings) in the database, does this make it simpler because I don't have to worry about data types?

  • How are you using the Managed Extensibility Framework?

    - by dboarman
    I have been working with MEF for about 2 weeks. I started thinking about what MEF is for, researching to find out how to use MEF, and finally implementing a Host with 3 modules. The contracts are proving to be easy to grasp and the modules are easily managed. Although MEF has a very practical use, I am wondering to what extent? I mean, is everyone going to be rewriting existing applications for extensibility? Yes, that sounds, and is insanely impractical. Rhetorically speaking: how is MEF affecting the current trends in programming? have you begun looking for opportunities to use MEF? have you begun planning a major re-write of an existing app that may benefit from extensibility? That said, my questions are: how do I know when I should plan a new project with extensibility? how will I know if an existing project needs to be re-written for extensibility? Is anyone using MEF?

  • Restrictive routing best practices for Google App Engine with python?

    - by Aleksandr Makov
    Say I have a simple structure: app = webapp2.WSGIApplication([ (r'/', 'pages.login'), (r'/profile', 'pages.profile'), (r'/dashboard', 'pages.dash'), ], debug=True) Basically all pages require authentication except for the login. If visitor tries to reach a restrictive page and he isn't authorized (or lacks privileges) then he gets redirected to the login view. The question is about the routing design. Should I check the auth and ACL privs in each of the modules (pages.profile and pages.dash from example above), or just pass all requests through the single routing mechanism: app = webapp2.WSGIApplication([ (r'/', 'pages.login'), (r'/.+', 'router') ], debug=True) I'm still quite new to the GAE, but my app requires authentication as well as ACL. I'm aware that there's login directive on the server config level, but I don't know how it works and how I can tight it with my ACL logic and what's worse I cannot estimate time needed to get it running. Besides, it looks only to provide only 2 user groups: admin and user. In any case, that's the configuration I use: handlers: - url: /favicon.ico static_files: static/favicon.ico upload: static/favicon.ico - url: /static/* static_dir: static - url: .* script: main.app secure: always Or I miss something here and ACL can be set in the config file? Thanks.

  • APIs that deal with logins

    - by Brandon Still
    I have been asked to make a mobile app for a friends website. The website is a Multi level marketing site that sells products and franchises. A client logs in in to the website and can view his or her dashboard ( user can view team members, business volume, commissions, invoices, etc.) The app is supposed to bring the dashboard to user's mobile devices (w/ some added features). The company does not have any APIs that deal with interaction or authentication, and I am new to the whole secure login side of app development. My questions is this, how do I let the users gain access to their information via my app from the secure website when there is no API?

  • How to coach a developer with dyslexia to improve his spelling and grammar capabilities?

    - by Uwe Keim
    Just having read this question regarding developers with dyslexia, I still have some open questions on how to deal with it: I am working on a project sinc approx. 6 month with a new developer who just finished university. I see that the code quality is high, what he's missing is the ability to write texts (even short ones) in an error-free manner (both, syntax and grammar errors). He is working on some UI stuff (VS.NET 2010, ASP.NET 4) and, beside coding, has to write short text for labels, buttons, grid view headers, page titles, etc. Since even those texts have errors inside, no matter how much I try to discuss the need for a professional, text-error-free UI, he seems to not manage to get this right, although he really tries. So my questions are: Are there any hints how he (or I) should proceed to enhance the text quality? Do you know any tools (like inline spell checkers) for VS.NET to highlight syntax and grammar errors? (We are working on a German-only UI, if this is important to know)

  • What do you do about content when someone asks you to build a website

    - by Jon
    I am an experienced asp.net developer and asp.net mvc and I have my own CMS that I have written but starting to think there should be another approach. When someone asks you to develop them a website how do you develop it so that they can add pictures,slideshows, content, news items, diary events. On a side note do you give them a design for the home page and inner page and thats it. I'm just thinking if they turn around and say 6 months down the line I want a jquery slideshow on the right hand side of this page how do you or CMS's handle it?

  • Is there an alternative to HTML Web Sockets, now that Firefox 4 has disabled them?

    - by Pino
    I've been checking out some of the latest multiplayer engines in HTML all supporting multi-user games (Very nice) - I believe all these engines use Web Sockets for communication. That’s why we’ve decided to disable support for WebSocket in Firefox 4, starting with beta 8 due to a protocol-level security issue. Beta 7 of Firefox has support for the -76 version of the protocol, the same version that’s included with Chrome and Safari. Beta 8 of Firefox 4 will remove that support. Anne van Kesteren of Opera also announced that Opera are dropping Websocket support. We are confident that other browser developers will follow. Source: Websockets Disabled in FireFox 4 I've just come accross the above, so no sockets in Firefox 4 or Opera.... thats big. Is anyone aware of an alternate or is it Chrome or do we need to just sit and wait for the next release of the major browsers. More info : Rocket Engine appears to work with all browsers including IE8 (http://rocketpack.fi/engine/) what will it be using as a method of communication?

  • Mono is frequently used to say "Yes, .NET is cross-platform". How valid is that claim?

    - by Thorbjørn Ravn Andersen
    In What would you choose for your project between .NET and Java at this point in time ? I say that I would consider the "Will you always deploy to Windows?" the single most important decision to make up front in a new web project, and if the answer is "no", I would recommend Java instead of .NET. A very common counter-argument is that "If we ever want to run on Linux/OS X/Whatever, we'll just run Mono", which is a very compelling argument on the surface, but I don't agree for several reasons. OpenJDK and all the vendor supplied JVM's have passed the official Sun TCK ensuring things work correctly. I am not aware of Mono passing a Microsoft TCK. Mono trails the .NET releases. What .NET-level is currently fully supported? Does all GUI elements (WinForms?) work correctly in Mono? Businesses may not want to depend on Open Source frameworks as the official plan B. I am aware that with the new governance of Java by Oracle, the future is unsafe, but e.g. IBM provides JDK's for many platforms, including Linux. They are just not open sourced. So, under which circumstances is Mono a valid business strategy for .NET-applications?

  • Identifying the best pattern

    - by Daniel Grillo
    I'm developing a software to program a device. I have some commands like Reset, Read_Version, Read_memory, Write_memory, Erase_memory. Reset and Read_Version are fixed. They don't need parameters. Read_memory and Erase_memory need the same parameters that are Length and Address. Write_memory needs Lenght, Address and Data. For each command, I have the same steps in sequence, that are something like this sendCommand, waitForResponse, treatResponse. I'm having difficulty to identify which pattern should I use. Factory, Template Method, Strategy or other pattern.

  • Do you use your personal laptop for work?

    - by davekaro
    We're trying to get our company to let us use our own personal laptop for client work. We've agreed that any code/data will be encrypted using something like TrueCrypt, in case the laptop is stolen or lost. However, the company is still skeptical and not sure they want to allow us to use our personal machines for development. They would rather buy us laptops... but we want to use MacBook Pros and they don't want to pay for them. Even if they did buy us laptops, we would stil have the issue of needing to encrypt the code/data in case of theft/loss. Do you use your own laptop for work? What are the arguments for/against this?

  • SOA, Java EE and data organization

    - by jolasveinn
    At the company I work for, we're currently splitting up our monolith solution into a number of small services (SOA). Many of the services are small, so we'd like to deploy a number of these services on the same application server, JBoss 7.1 in this case. As per the SOA philosophy, the independence of each service and the teams working on them is very important. What would be the best way to organize the data? Use one schema per service Would you use one datasource per schema in the application server? Or use one datasource, prefixing all DB object names with the schema name in some transparent manner? Use a shared schema, but evading any naming collisions by requiring each service to use a distinct prefix for all DB objects Other options? Am I maybe thinking this completely wrong here? :)
