• How do you support your code post employment end?

  - by James

  What is the process for leaving a company (or even a group/division) in terms of code support? Is it best to handle all questions? Do you give the remaining developers access to yourself as a future resource? If so, is there a way to not give full access? I've experienced first hand where answers about the general software arthitecture from the initial developer would be invaluable. I understand that if serious assistance is needed, than it becomes a typical case of employment negotiation as a support contract. However, should serious assistance be required, what steps can you make to ease that process of contacting you? I was thinking of doing something like making a (YOUR_NAME)_codesupport @ (YOUR_FAVORITE_EMAIL_CLIENT).com address. My Situation Specifics: I'm a co-op student, and as such bounce around companies on 4-month stints. This means introducing myself to a lot of new code bases, as well as leaving a fair share of orphaned code behind when I leave a company. I feel bad if I leave junk code around.

• OS choice for functional developing

  - by Carsten König

  I'm mainly a .NET developer so I normaly use Windows/VisualStudio (that means: I'm spoiled) but I'm enjoying Haskell and other (mostly functional) languagues in my spare time. Now for Haskell the windows-support is ok (you can get the Haskell-Platform) but latley I tried to get a basic Clojure/Scheme environment set up and it's just a pain on windows. So I'm thinking about trying out another OS for better tooling and languague support. Of course that leaves me with MacOS or some Linux distribution. I never used MacOS before and of course Linux would be cheaper (free) and I don't think I can parallel-boot MacOS on your normal PC-Hardware (can you?). PLUS: I don't have a clue about the tools you can use on those (to me) forign OSs. To make it short: I want to explore more Haskell, Clojure, Scala, Scheme and of course need at least good tooling for JavaScript/HTML5/Css. Support for .NET/Mono/F# would be great but for this I will still have my Win7 boot. So I like to know: - what is your prefered OS, Distribution (is Ubuntu viable?) - what Editor/IDE are you using Thank you for your help! PS: I'm not sure if this is the right place for this question but I surely hope so - if not please let me know where I should move this to (StackOverflow don't seem to be the right place IMHO)

• How to get Visual Studio 2010 Express Edition on Windows 7

  - by thanigai

  Visual studio 2010 is an amzing release from Microsoft. I have tried the beta 1,2 of Visual Studio 2010 and finally the full version is released. I am also interested in the latest edition of Windows which nothing but our Windows 7. Next to Vista I like this version very much. Out of curiosity I have installed the prebuild version of Windows 7. I tried installing the express edition here and it failed making me disappointed. I tried two or three times and finally I decided to download the trial version of Windows 7. After that I can install the Visual Studio 2010 express edition easily. I have given the link below from where I have downloaded the file. http://www.microsoft.com/express/downloads/ Here the link give is through Web PI Installer. Other option is you can download the ISO image file and burn them to a disc or use a virtual disc This Visual Web developer will provide the Sql Server engine alone. To get a Sql Server Management Studio get from the following link http://www.microsoft.com/express/Database/InstallOptions.aspx That's it all the things necessary for the web application programming is ready. Ah I forget to tell about the Silverlight. Please find the Silverlight 4 latest tools from the below link (WCF RIA services is the main update) http://www.silverlight.net/getstarted/ Silverlight 4 Tools(http://www.microsoft.com/downloads/details.aspx?FamilyID=eff8a0da-0a4d-48e8-8366-6ddf2ecad801&displaylang=en) Expression Blend 4 trial(http://www.microsoft.com/downloads/details.aspx?FamilyID=88484825-1b3c-4e8c-8b14-b05d025e1541&displaylang=en) I think the reader would have enjoyed on how to get these things. Please let me know if you are not clear with any of these things.  Thanks, Thani

• Happy Day! VS2010 SP1, Project Server Integration, Load Test Feature Pack

  - by Aaron Kowall

  Microsoft released a PILE of Visual Studio goodness today: Visual Studio 2010 SP1(Including TFS SP1) Finally done with remembering which GDR packs, KB Patches, etc need to be installed with a new VS/TFS 2010 deployment.  Just grab the SP1.  It’s available today for MSDN Subscribers and March 10th for public download. TFS-Project Server Integration Feature Pack MSDN Subscribers got another little treat today with the TFS-Project Server integration feature pack.  We can now get project rollups and portfolio level management with Project Server yet still have the tight developer interaction with TFS.  Finally we can make the PMO happy without duplicate entry or MS Project gymnastics. Visual Studio Load Test Feature Pack This is a new benefit for Visual Studio 2010 Ultimate subscribers.  Previously there was a limit to Ultimate Load Testing of 250 virtual users. If you needed more, you had to buy virtual user license packs.  No more.  Now your Visual Studio Ultimate license allows you to simulate as many virtual users as you need!!  This is HUGE in improving adoption of regular load testing for development projects. All the Details are available from Soma’s blog. Technorati Tags: VS2010,TFS,Load Test

• Does this licensing clause allow redistribution of this application?

  - by George Edison

  As a software developer, I find a frequent need to create icons for my applications. Nothing has ever worked as well as IcoFX for this purpose. Unfortunately, the program is no longer free - but I still have the installer for an older version. My question is whether or not I can distribute copies of the installer. The license agreement contains the following pertinent clauses: 6. All redistributions of the Software's files must retain all copyright notices and web site addresses that are currently in place, and must include this list of conditions without modification. 7. None of the Software's files may be redistributed for profit or as part of another Software package without express written permission of the Author. 10. The Author reserves his rights to modify this agreement in the future. The first two clauses would seem to suggest that I can legally distribute verbatim copies of the installer but the last clause has me confused. If the author modifies the agreement and removes the ability to distribute copies, does it apply to my copy that I downloaded a while back?

• Dealing with inflexible programmers.

  - by Singleton

  Sometimes programmers who work on a project for long time get inflexible, and it becomes difficult to reason with them. Even if we do manage to convince them, they can be unlikely to implement our suggestions. For instance, I recently joined a project where the build & release process is too complicated and has unnecessary roadblocks. I suggested that we get rid of some of the development overhead (like filling a few spreadsheets) just by integrating defect management and version control tools (both are IBM-Rational tools so integration can be a very easy one-off effort). Also, if we use tools like Maven & Ant (the project involves Java and some COTS products) build & release can be simplified which should reduce manual errors & intervention. I managed to convince others and I'm ready to put in the effort to develop a proof of concept. But the ‘Senior’ developer is not willing, possibly because the current process makes him more valuable. How do we handle this situation without developing friction in the team?

• What do you wish language designers paid attention to?

  - by Berin Loritsch

  The purpose of this question is not to assemble a laundry list of programming language features that you can't live without, or wish was in your main language of choice. The purpose of this question is to bring to light corners of languge design most language designers might not think about. So, instead of thinking about language feature X, think a little more philisophically. One of my biases, and perhaps it might be controversial, is that the softer side of engineering--the whys and what fors--are many times more important than the more concrete side. For example, Ruby was designed with a stated goal of improving developer happiness. While your opinions may be mixed on whether it delivered or not, the fact that was a goal means that some of the choices in language design were influenced by that philosophy. Please do not post: Syntax flame wars (I could care less whether you use whitespace [Python], keywords [Ruby], or curly braces [Java, C/C++, et. al.] to denote program blocks). That's just an implementation detail. "Any language that doesn't have feature X doesn't deserve to exist" type comments. There is at least one reason for all programming languages to exist--good or bad. Please do post: Philisophical ideas that language designers seem to miss. Technical concepts that seem to be poorly implemented more often than not. Please do provide an example of the pain it causes and if you have any ideas of how you would prefer it to function. Things you wish were in the platform's common library but seldom are. One the same token, things that usually are in a common library that you wish were not. Conceptual features such as built in test/assertion/contract/error handling support that you wish all programming languages would implement properly--and define properly. My hope is that this will be a fun and stimulating topic.

• Strategy for hosting 700+ domains names, each with a static HTML site

  - by jonschlinkert

  I have a portfolio of more than 700 domain names, and ideally I'd like to put up a single-page HTML/CSS/JavaScript webpage for each domain. Is there a system/strategy/workflow that will allow me to: Automate the deployment of new websites, quickly and easily without having to manually initiate each new website in an admin panel. For instance, I've seen dropbox-based solutions that claim to make it simple to setup new websites on your dropbox account, but you still have to set each one up in an admin interface first. It would be so much easier to have a folder naming convention that allowed the user to easily clone/copy/duplicate sites inside their Dropbox App folder (https://www.dropbox.com/developers/blog/23) to create new ones. Sounds interesting, however... It's easy to manage CNAMEs on the registrar-side, but is there a way to quickly associate CNAMEs with new websites (on the hosting side), maybe using the method offered by gh-pages-style (https://help.github.com/articles/setting-up-a-custom-domain-with-pages)? With GitHub's gh-pages, all you have to do is drop a file called CNAME into your repo, with the domain name you want associated with the repo inside the file. gh-pages isn't a good solution for what I'm doing though unfortunately. I'm also a front-end developer, specializing in rapid web development and "front-end build systems", so I building and maintaining static assets for hundreds of sites is no problem. It's the hosting-side that I really struggle with. Any suggestions?

• How do you save/export changes made in Firebug?

  - by blunders

  Using Firebug to edit CSS, how do I save/export changes made to the CSS? TOOLS: Firefox, Firebug MAJOR UPDATE: If you know of a way to lock the forward/back/refresh on a FireFox tab, please let me know. Otherwise, I've given up on using FireBug/FireDiff as an IDE for CSS, it's nice, but lol... press backspace at the wrong time and ALL your work is gone... funny. So, really like the browser highlighting to CSS/HTML in Firebug. Know any good CSS editors that do this? Really had hope FireBug would work, but for now only see it as being good for ad-hoc inspection and test; meaning using it for what it's made for. UPDATES: @Lèse majesté: Just as an update, "Web Developer add-on" does let you edit CSS, but it does not let you edit/save CSS changes made by Firebug. Meaning you use Firebug to ID and maybe test changes, but it does not let you save the changes from Firebug. Here's a "how to" covering how to use them together: FF + FB + WD @Lèse majesté: Still playing around with FireDiff. It works okay, found one bug already (although I'm just working around it), and there's no "how to" I've been able to find, so I'm just trying every feature and clicking around... (for example, to export a diff you must be over the last item in the list, right click, and select as "Save Diff". The ".diff" is just a text file, no idea why at this point the ext is .diff.

• Baseline for GIS Applications

  - by Geertjan

  The application I introduced here yesterday can best be understood via its author's explanation: "As I developed several different WorldWind-based applications, I noticed that they all started out the same. Terramenta was born so I wouldn't have to recreate the baseline every time, I could just provide NetBeans plugin modules to introduce the new features required by different projects." So, to try it out for myself, I checked out the sources from the Mercurial repo today, built them, and ran them. hg clone https://bitbucket.org/heidtmare/terramenta On Windows, things worked fine, on Ubuntu they didn't because the relevant native libraries aren't provided yet out of the box. Here's the result: The above provides the WorldWind globe, together with all the standard options, e.g., for showing names and other WorldWind features, together with several features that I don't understand yet, such as tools for creating shapes and a recorder for replaying sequences. The complete application is like this, i.e., one single functionality module is provided, which exposes several API packages that can be extended: It would really be cool if the above module could also be added to a Maven-based application via a reference to a Maven repository, in the way that Timon Veenstra and the AgroSense team have made available their GeoViewer. One cool thing from the GeoViewer solution is the Flamingo menubar, which I added to Terramenta by simply putting the dependency below into the application POM: <dependency>    <groupId>nl.cloudfarming.client</groupId>    <artifactId>menu</artifactId>    <version>1.0.24</version></dependency> The result, without doing anything other than the above: I am looking forward to helping to document the use cases and developer scenarios for Terramenta! Something like this, created by Timon to demonstrate the GeoViewer use case would be cool to have: http://java.net/projects/agrosense/pages/ExampleGeoviewerNormal

• Changing Launchpad username, and How to know what sites will be affected?

  - by Daniel Clem

  I am setting up my developer profile on Launchpad, and would like to change my username so it would be same as other sites I use, as well as better reflect me as a person. (that's a much more important thing than it sounds) I want to do this now while I can, because as I understand it, once I set up a PPA it will be impossible to change it due to the username being locked into the PPA URL's to prevent breakages and other problems. But when trying to change my username, it warned me with this message. "Changing your name will change your public OpenID identifier. This means that you might be locked out of certain sites where you used it, or that somebody could create a new profile with the same name and log in as you on these third-party sites." How can I find out which sites will be locked out, and how to still change the username while preventing problems with other sites? Sorry if this is actually a question for Launchpad itself. But I don't know where to post questions like this on the Launchpad site. Edit I understand that it is an issue with OpenID. But how am I to know what sites will be affected? And how do i fix the problems this will cause? Can't I just reset the password (and as a side affect, re-establish the connection with the new username) using my email address?

• A Great Work : ADF Architecture TV

  - by mustafakaya

  I would like to information about Oracle ADF Product Management's great work ; ADF Architecture TV. This channel has various subjects such as before start a new ADF or any software project what will you need or how can you select team member's skills, or how to implement and design an ADF projects etc. When developing with a new technology, one of the challenges for technical staff is to both learn the features of the technology and how to implement them, and also consider the broader concepts of design, engineering and architecture. Many an IT project has come undone because IT staff have been focused on the nitty gritty details of writing software, rather than looking at the "bigger picture" of how it will all go together. Oracle's "ADF Architecture TV" plans to address this issue by focusing on architectural issues and developer guidelines for writing ADF software solutions. The goal, to give ADF developers an understanding of the decisions you need to build a successful ADF application, potential architectural blueprints to choose from when putting the ADF application together, and potential best practices to take back to your development team.  You can click here for ADF Architecture TV.

• Help me choose an Open-Source license

  - by Spartan-117A

  So I've done lots of open-source work. I have released many projects, most of which have fallen under GPL, LGPL, or BSD licensing. Now I have a new project (an implementation library), and I can't find a license that meets my needs (although I believe one may exist, hence this question). This is the list of things I'm looking for in the license. Appropriate credit given for ALL usage or derivative works. No warranty expressed or implied. The library may be freely used in ANY other open-source/free-software product (regardless of license, GPL, BSD, EPL, etc). The library may be used in closed-source/commercial products ONLY WITH WRITTEN PERMISSION. GPL - Useless to me, obviously, as it completely precludes any and all closed-source use, violating requirement (4). BSD/LGPL/MIT - Won't work, because they wouldn't require closed-source developers to get my permission, violating requirement (4). If it wasn't for that, BSD (FreeBSD in particular) would look like a good choice here. EPL/MPL - Won't work either, as the code couldn't be combined with GPL-code, therefore violating requirement (3). Also I'm pretty sure they allow commercial works without asking permission, so they don't meet (4) either. Dual-licensing is an option, but in that case, what combination would hold to all four requirements? Basically, I want BSD minus the commercial use, plus an option to use in commercial/closed-source as long as the developer has my written permission. EDIT: At the moment, thinking something like multiple-licensing under GPL/LGPL plus something else for commercial?

• How do I get others to see past my prior inexperience?

  - by Kevin

  My core question is how do I proceed from the following predicament. I will be honest with you, I wasted my College Experience. I slacked off and didn't take any of my comp sci classes that seriously, somehow i still got out with a 3.25 GPA. But truth be told I learned nothing. I befriended most of my professors who went pretty lenient on me in terms of grading. However, I basically came out of College knowing how to program a simple calculator in VB.Net. I was (to my great surprise) hired by a very large respected company in Denver as a Junior developer. Well the long and the short of it is that I knew so little about programming that I quickly became the office pariah and was almost fired due to my incompetence. It has been 8 months now and I feel I have learned some basic things and I am not as picked on as I used to be by the other developers. However, everyone hates me and the first few months have given the other developers a horrible perception of me. I am no longer afraid of code or learning, but I have put my self in the precarious position of being the scapegoat of our department. I hate going to work every day because no one there is my friend and pretty much everyone is hostile to me. What should I do? Any advice?

• How to get feedback from the community on large chunks of code?

  - by MainMa

  Code Review.SE is great when you need feedback on a precise, short piece of code. But where to get similar feedback about the code itself when: you have thousands of LOC, don't have colleagues in your workplace ready or willing to review the code¹, don't have thousands of dollars to spend for a professional review by a third party developer?² Places like CodePlex are a good idea to get your project known³, but from what I've seen, the feedback you get on known projects are consumer feedback, i.e. concerns the bugs and feature requests, not the quality of the source code itself. What are the social way to get the community involved in the code review of the codebase of a certain size for an open source project which doesn't have the scale of Firefox or similar products? ¹ Which is the case for most personal and open source projects, or projects done in companies where the practice of regular and complete code review is nonexistent. ² Which is, again, the case for most personal and open source projects. ³ Even if too many projects published on CodePlex never get known, either because nobody cares or because they are presented not very well.

• Facebook App EULA & Restrictions: What can't they do that my web app can?

  - by Adam Tannon

  I have written a nifty little web app (in Java/GWT/JS) and have been experimenting with the idea of making it available through Facebook as a Facebook App as well. After spending some time reading Facebook's developer docs, it seems like I can just create a Facebook App to point at any URL I want and use that as the app/canvas. It accomplishes this via iframes. So, my tentative plan is to just point it towards my (existing) web app so that I don't have to totally re-write it. But then that got me thinking: Facebook must regulate what sorts of things can be done through a Facebook App, vs. what an app can't do. For instance, I can't imagine I can point a Facebook App to point at a URL for a web app that accepts e-commerce payments (that would by-pass Facebook altogether and not allow them to take a cut from the ecom transaction!). Also, I can't imagine that Facebook allows developers to point their Facebook Apps to just any old URL without some sort of a scan, otherwise that would open Facebook up to the horrors of every security threat knownst to humanity. I know for a fact that when you write an iOS native app and put it up on the Apple App Store, that Apple actually scans your source code for violations of their EULA. So my question: does Facebook do the same? If so, what are their terms & conditions for what a Facebook app can/can't do? Suprisingly, I can't find this anywhere!! Thanks in advance!

• Usual Suspects: Typical 3rd Party Entities in E-Commerce [closed]

  - by zharvey

  I am doing some requirements/analysis for a web app that I'd like to build (Ruby/Java developer here). This web app would have a store front, shopping cart and would need to be totally compliant with all e-com best practices. It's amazing how much non-technical info comes up when you search for phrases like "how does e-commerce work", but very little comes up in the way of technical details. As such, I'm having extreme frustration finding answers to what I consider pretty straight-forward questions. I came here because I believe this question is not off-topic; if it is, please leave a comment as to why this question does not belong here and I will happily remove it myself (upvotes if your comment can point me to the correct place for this question!). So then: What 3rd parties will I need to work with to have a modern, web-compliant e-com site? So far I can account for a payment gateway provider like Authorize.net and an SSL certificate provider like Trustwave. Any others? What other standards besides PCI compliance will I be held to (besides governing laws, of course!)? Vulnerability scans: PCI compliance requires quarterly scans: if I'm a "Level 4" (low volume) Merchant does that still apply to me? Irregardless, my backend architecture is quite huge, with web servers, app servers, database, message brokers and more. Do each of these servers need to be scanned?!? If not what servers do need to get these quarterly scans? I usually hate to ask micro-questions inside of one large one, but these are so closely-related I just felt like asking them all separately would be spamming the site with too many petty questions. Thanks in advance!

• .html extension or no for SEO purposes

  - by Scott Schluer

  I know this question has been asked before on Stack Overflow, but what I have not been able to find in the posts I've read are concrete references as to WHY one is better than the other (something I can take to my boss). So I'm working on an MVC 3 application that is basically a rewrite of the existing production application (web forms) using MVC. The current site uses a URL rewriter to rewrite "friendly" urls with HTML extensions to their ASPX counterpart. i.e. http://www.site.com/products/18554-widget.html gets rewritten to http://www.site.com/products.aspx?id=18554 We're moving away from this with the MVC site, but the powers that be still want the HTML extension on the URLs. As a developer, that just feels wrong on an MVC site. I've written a quick and dirty HttpModule that will perform a 301 redirect from the .html URL to the same URL without the .html extension and it works fine, but I need to convince management that removing the .html extension is not going to hurt SEO. I'd prefer to have this sort of friendly URL: http://www.site.com/products/18554-widget Can anyone provide information to back up my position or am I actually trying to do something that WOULD hurt SEO, in which case can you provide references on that?

• How to change careers

  - by Jack Black

  For the past 4 years I have worked in c# doing web development. I have really enjoyed it, learnt a lot and have a worked hard to get to a position where I am earning good money and enjoy the work. However lately - I have wanted a change. What with the "native renaissance" I would like to change my career from being high level application and web development to more down to the metal native development. I haven't done any c or c++ since Uni over 4 years ago and so I have begun reading text books and websites to brush up. However - one major issue I have is that I have no practical experience with C++ and although I am brushing up on it, there will be a lot I don't know. Most of the jobs I have seen in native code around me all require native experience. The only positions I can find that don't explicitly ask for native experience are junior level positions. In my current role I am a mid level developer and although there would be a lot to learn in a c++ position, I wouldn't class myself as a junior. I guess my question is, how do people solve this issue when changing programming languages for their profession and / or how would you approach this hurdle? Like I said, I would really like to try out native development professionally but I wouldn't want to move back to a junior role. Would employers consider years of managed development and native hobby projects enough experience?

• ASP.NET Webforms developers and web designers: how to interact?

  - by just_name

  I'm an ASP.NET Webforms developer, and I face some problems when I deal with designers. Designers always complain about the asp.net server controls. They'd rather just have an html file and create css files along with the required images to go with those. Sometimes, if the design phase is done in advance, I get html files with related css files, but then we face many problems integrating the design with the aspx files (sever controls an telerik controls ... etc). What I want to ask about is: How do I overcome these problems? The designers prefer php- and mvc developers because of the problems with .net server controls. I need to know how to interact with the designers in the correct way. Are there any tools or applications to provide the designers with the rendered (html page) of the .aspx pages? By that I mean the page in runtime rather than the aspx in Visual Studio. They do use Web Expression but they want the rendered page in html as well.

• TransformXml Task locks config file identified in Source attribute

  - by alexhildyard

  As background: the TransformXml MSBuild task is typically invoked in a custom build step to mark up a web.config file with per-environment configuration; its flexible directives offer highly granular control over the insertion, removal, substitution and transformation of existing configuration hierarchies. For those using the TransformXML task (typically in a Web Deployment Project) I raised an issue against Visual Studio 2010, in which the file handle on the input file was not released, meaning that following transformation the source file remained locked. As a result, the best way to transform a file was first to rename it, transform it, and then copy it back, leaving the "locked" file to be freed up later.I just heard today that this has now been resolved in Visual Studio 2012 RTM. That's good news, because Web Config Transformations offer a lot. An intelligent, automated build process will swap in the relevant transform(s), making it much easier to synthesise the Developer and Build server builds. This makes for a simpler and more exemplary build process, and with the tighter coupling comes a correspondingly quicker response to Developmental change.Oh, and don't forget -- it isn't just web.configs you can transform.

• Wanted: Java Code Brainteasers

  - by Tori Wieldt

  The Jan/Feb Java Magazine will go out next week. It's full of great Java stories, interviews and technical articles. It also includes a Fix This section; the idea of this section is challenging a Java developer's coding skills. It's a multiple-choice brainteaser that includes code and possible answers. The answer is provided in the next issue. For an example, check out Fix This in the Java Magazine premier issue. We are looking for community submissions to Fix This. Do you have a good code brain teaser? Remember, you want tease your fellow devs, not stump them completely! If you have a submission, here's what you do:  1. State the problem, including a short summary of the tool/technique, in about 75 words. 2. Send us the code snippet, with a short set-up so readers know what they are looking at (such as, "Consider the following piece of code to have database access within a Servlet.") 3. Provide four multiple-choice answers to the question, "What's the fix?" 4. Give us the answer, along with a brief explanation of why. 5. Tell us who you are (name, occupation, etc.) 6. Email the above to JAVAMAG_US at ORACLE.COM with "Fix This Submission" in the title. Deadlines for Fix This for next two issues of Java Magazine are Dec. 12th and Jan. 15th. Bring It!

• How is determined an impact of a requirement change on the existing code?

  - by MainMa

  Hi, How companies working on large projects evaluate an impact of a single modification on an existing code? Since my question is probably not very clear, here's an example: Let's take a sample business application which deals with tasks. In the database, each task has a state, 0 being "Pending", ... 5 - "Finished". A new requirement adds a new state, between 2nd and 3rd one. It means that: A constraint on the values 1 - 5 in the database must be changed, Business layer and code contracts must be changed to add a new state, Data access layer must be changed to take in account that, for example the state StateReady is now 6 instead of 5, etc. The application must implement a new state visually, add new controls for it, new localized strings for tool-tips, etc. When an application is written recently by one developer, it's more or less easy to predict every change to do. On the other hand, when an application was written for years by many people, no single person can anticipate every change immediately, without any investigation. So since this situation (such changes in requirements) is very frequent, I imagine there are already some clever techniques and ways to predict the impact. Is there any? Do you know any books which deal about this subject? Note: my question is not related to How do you deal with changing requirements? question. In fact, I'm not interested in evaluating the cost of a change, but rather the way to predict the parts of an application which will be concerned by the change. What will be those changes and how difficult they are really doesn't matter in my question.
