  • Chrome "refusing to execute script"

    - by TestSubject528491
    In the head of my HTML page, I have: <script src="https://raw.github.com/cloudhead/less.js/master/dist/less-1.3.3.js"></script> When I load the page in my browser (Google Chrome v 27.0.1453.116) and enable the developer tools, it says Refused to execute script from 'https://raw.github.com/cloudhead/less.js/master/dist/less-1.3.3.js' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled. Indeed, the script won't run. Why does Chrome think this is a plaintext file? It clearly has a js file extension. Since I'm using HTML5, I omitted the type attribute, so I thought that might be causing the problem. So I added type="text/javascript" to the <script> tag, and got the same result. I even tried type="application/javascript" and still, same error. Then I tried changing it to type="text/plain" just out of curiosity. The browser did not return an error, but of course the JavaScript did not run. Finally I thought the periods in the filename might be throwing the browser off. So in my HTML, I changed all the periods to the URL escape character %2E: <script src="https://raw.github.com/cloudhead/less%2Ejs/master/dist/less-1%2E3%2E3.js"></script> This still did not work. The only thing that truly works (i.e. the browser does not give an error and the JS successfully runs) is if I download the file, upload it to a local directory, and then change the src value to the local file. I'd rather not do this since I'm trying to save space on my own website. How do I get the Chrome to recognize that the linked file is actually a javascript type?

  • We're Subversion Geeks and we want to know the benefits of Mercurial

    - by Matt
    Having read I'm a Subversion geek, why should I consider or not consider Mercurial or Git or any other DVCS. I have a related follow up question. I read that question and read the recommended links and videos and I see the benefits but I don't see the overall mindshift people are talking about. Our team is of 8-10 developers that work on one large code base consisting of 60 projects. We use Subversion and have a main trunk. When a developer starts a new Fogbugz case they create a svn branch, do the work on the branch and when they're done they merge back to the trunk. Occasionally they may stay on the branch for an extended time and merge the trunk to the branch to pick up the changes. When I watched Linus talk about people creating a branch and never doing it again, that's not us at all. We create probably 50-100 branches a week without issue. The biggest challenge is the merging but we've gotten pretty good at that as well. I tend to merge by fogbugz case & checkin rather than the entire root of the branch. We never work remotely and we never make branches off of branches. If you're the only one working in that section of the code base then the merge to the trunk goes smoothly. If someone else had modified the same section of code then the merge can get messy and you might need to do some surgery. Conflicts are conflicts, I don't see how any system could get it right most of the time unless if was smart enough to understand the code. After creating a branch the following checkout of 60k+ files takes some time but that would be an issue with any source control system we'd use. Is there some benefit of any DVCS that we're not seeing that would be of great help to us?

  • GitHub: Are there external tools for managing issues list vs. project backlog

    - by DXM
    Recently I posted one of my the projects1 on GitHub and as I was exploring capabilities of the site, I noticed they have a rather decent issue tracking section. I want to use that section as a) other people can report bugs if they'd like and b) other people can see which bugs I'm aware of. However, as others have noted, issues list cannot be prioritized in order to create a project backlog. For now my backlog has been a text file, but I'd like to be able to have it integrated so the same information isn't maintained in different places. Having a fully ordered list, which is something we also practice at work, has been very useful as I can open one file, start with line 1 and fire off 2 or 3 items in one sitting without having to go back to a full issues/stories bucket. GitHub doesn't offer this. What GitHub does offer is a very nice and clean API so issues can easily be exported into anything else. I've searched to see if there are other websites (like Trello) that integrate with GitHub issues, but did not find anything. Does anyone know of such a product, service or offline tool? Those that use GitHub, what is your experience in managing backlog? I kinda hate the idea of manually managing two disconnected lists like some people seem to be doing with Wiki project pages. 1 - are shameless plugs allowed no this site? Searched but didn't find a definite answer. If it's bad practice, STOP and don't read further As a developer I got sick and tired of navigating to same set of folders 30 times a day, so I wrote a little, auto-collapsible utility that gets stuck to the desktop and allows easy access to the folders you constantly use.

  • On what criteria should I evaluate domain registrars?

    - by jdotjdot89
    Though I've been a web developer for a fair amount of time, I am going for the first time to buy a few domain names. I have looked into the domains I'm going to buy and know that they're available, and I've been looking into which sellers to use. After doing a lot of research, the main ones I'm considering are 1&1, Namecheap, and Gandi. The problem is, when continuing to research, I'm not really sure what makes one domain seller distinct from another. I don't need much in the way of services--definitely not hosting, since I plan to use Heroku for that. I mainly only need the domain itself and DNS management, as well as possibly SSL certificates and WHOIS protection. Question: What makes one domain seller different from another? How can I go about evaluating which one is the best for me? Note: This question is not which domain seller is the best, but rather, what criteria can I use to evaluate them and rank one over another. I'm trying to find out what makes one domain seller different from another, since they all seem to be pretty similar to me right now.

  • Open World Session - BPM, SOA and ADF Combined:Patterns learned from Fusion Applications

    - by mesriniv
    Blog by Meera Srinivasan (Oracle Product Management) Today afternoon (10/2/2012), Mohan Kamath, and I (Meera Srinivasan) delivered an Open World session on how Oracle Fusion Applications (the next generation business applications from Oracle), use Oracle BPM, Oracle SOA and Oracle ADF products. These adoption patterns can be applied in a generic manner to produce process-centric, user-centric, highly customizable and extensible next generation application. The session was well attended and we had lively discussions with the attendees during Q & A. We started with why as an application developer, you should look at BPM for creating a process-centric application and presented the following fusion adoption patterns Model driven agile development Customization and Extension Guided Process Interactions Personalization and Customization of End User Interfaces Approval Flows Fusion HCM, On Boarding Process - Activity Guide Interface was used as an example for the Guided Process Interactions adoption pattern and the Fusion CRM BPM Process Templates for Customization adoption pattern. In the Personalization and Customization of End User Interfaces section, we looked at how ADF is used within Oracle BPM and the various options available to customize end user interfaces. We also presented how Oracle Procurement does complex approvals using Rules and Approval Management Extensions. We hope you found the session useful, and please do try to attend Heidi’s session on dynamic case management: Case Management Patterns with Oracle Unified Business Process Management Suite.

  • How to hire support people?

    - by Martin
    I manage a tech support team at a mid-sized software company. We are the last line of support, so issues that we can't fix need to be escalated to the development team. When I joined the company, our team wasn't capable of much beyond using a specific set of troubleshooting steps to solve known issues and escalating anything else to the developers. It's always been a goal of mine for our team to shoulder as much of the support burden as possible without ever bothering a developer. Over the past few years, I, along with several new hires I've made, have made pretty good progress in that direction. We've coded our own troubleshooting tools which now ship with several of our products. When users have never-before-seen issues, we analyze stack traces and troubleshoot down to the code level, and if we need to submit a bug, half the time we've already identified in the code where in the code the bug is and offered a patch to fix it. Here's the problem I've always had: finding support people capable of the work I've described above is really difficult. I've hired 3 people in the past 3 years, and I've probably looked at several thousand resumes and conducted several hundred phone screens to do so. I know it's pretty well accepted that hiring good people is tough in the tech industry, but it seems that support is especially difficult -- there are clearly thousands of people walking around calling themselves support analysts, but 99%+ of them seemingly aren't capable of anything beyond reading a script. I'm curious if anyone has experience recruiting the sort of folks I'm talking about, and if you have any suggestions to share. We've tried all sorts of things -- different job titles/descriptions, using headhunters, etc. And while we've managed to hire a few good folks, it's basically taken us a year to find an appropriate candidate for each opening we've had, and I can't help but wonder if there's something we could be doing differently.

  • Script Task/Component and Template Information

    The Script Task and Script component are often used by people developing SSIS packages because they are easy to use and now because SSIS could be perceived to be more developer friendly they are very powerful. That being said we should no be using them everywhere.  There are generally Tasks/Components already provided that will do the job it may be that we have to rethink the way we want to draw our package. I had cause last week to break out the script component in SQL Server 2008 SP1 and found that it was broken.  I don’t know when it broke as I do not use them all that often.  My error was as below.     Something must have overwritten this template information.  I looked in Event Viewer and tried the things it suggested but the templates still did not work.  Here is how I got them eventually to work for me (Your Mileage may vary) Open up a Command Prompt window using an administrator level account and “as an administrator” vsta.exe /hostid SSIS_ScriptTask /setup vsta.exe /hostid SSIS_ScriptComponent /setup   This worked for me.  Hope it helps.

  • Agile development challenges

    - by Bob
    With Scrum / user story / agile development, how does one handle scheduling out-of-sync tasks that are part of a user story? We are a small gaming company working with a few remote consultants who do graphics and audio work. Typically, graphics work should be done at least a week (sometimes 2 weeks) in advance of the code so that it's ready for integration. However, since SCRUM is supposed to focus on user stories, how should I split the stories across iteration so that they still follow the user story model? Ideally, a user story should be completed by all the team members in the same iteration, I feel that splitting them in any way violates the core principle of user story driven development. Also, one front end developer can work at 2X pace of backend developers. However, that throws the scheduling out of sync as well because he is either constantly ahead of them or what we have done is to have him work on tasks that not specific to this iteration just to keep busy. Either way, it's the same issue as above, splitting up user story tasks. If someone can recommend an active Google agile development group that discusses these and other issues, that'll be great. Also, if you know of a free alternative to Pivotal Labs, let me know as well. I'm looking now at Agilo.

  • Does a mature agile team requires any management?

    - by ashy_32bit
    After a recent heated debate over Scrum, I realized my problem is that I think of management as a quite unnecessary and redundant activity in a fully agile team. I believe a mature Agile team does not require management or any non-technical decision making process whatsoever. To my (apparently erring) eyes it is more than obvious that the only one suitable and capable of managing a mature development team is their coach (who is the most technically competent colleague with proper communication skills). I can't imagine how a Scrum master can contribute to such a team. I am having great difficulty realizing and understanding the value of such things in Scrum and the manager as someone who is not a veteran developer but is well skilled in planning the production cycles when a coach exists in the team. What does that even mean? How on earth can someone with no edge-skills of development manage a highly technical team? Perhaps management here means something else? I see management as a total waste of time and a by-product of immaturity. In my understanding a mature team is fully self-managing. Apparently I'm mistaken since many great people say the contrary but I can't convince myself.

  • what is the Web development process efficiency judgment criteria

    - by Ahmed safan
    I'm working as a web developer and I want to be able to determine if I'm efficient. Does this include the how long it take to accomplish tasks such as: Server side code for the site logic with one language or multiple php,asp,asp.net. Client side code like javascript with jquery for ajax, menus and other interactivity Page layout, html, css (color, fonts (but I have no artistic sense!)) The needs of the site and how it will work (planning) How can i judge how long it will take to complete a website? The site has CMS for adding and editing news, products, articles on the experience of the company. Also, they can edit team work, add Recreational Activities and a logo gallery with compressed psd download, and send messages to cpanel and to email. You are starting from scratch except JQuery and PHPmailer. How can I estimate how long the job will take, and how can I calculate the required time to finish any new projects? I'm so sorry for many scattered questions, but I'm in my first experiment and I want to take benefits from the great experience of those who have it.

  • [Kubuntu 14.04][Eclipse] (ADT) crashes at button OK from Project properties

  • How do I use depth testing and texture transparency together in my 2.5D world?

    - by nbolton
    Note: I've already found an answer (which I will post after this question) - I was just wondering if I was doing it right, or if there is a better way. I'm making a "2.5D" isometric game using OpenGL ES (JOGL). By "2.5D", I mean that the world is 3D, but it is rendered using 2D isometric tiles. The original problem I had to solve was that my textures had to be rendered in order (from back to front), so that the tiles overlapped properly to create the proper effect. After some reading, I quickly realised that this is the "old hat" 2D approach. This became difficult to do efficiently, since the 3D world can be modified by the player (so stuff can appear anywhere in 3D space) - so it seemed logical that I take advantage of the depth buffer. This meant that I didn't have to worry about rendering stuff in the correct order. However, I faced a problem. If you use GL_DEPTH_TEST and GL_BLEND together, it creates an effect where objects are blended with the background before they are "sorted" by z order (meaning that you get a weird kind of overlap where the transparency should be). Here's some pseudo code that should illustrate the problem (incidentally, I'm using libgdx for Android). create() { // ... // some other code here // ... Gdx.gl.glEnable(GL10.GL_DEPTH_TEST); Gdx.gl.glEnable(GL10.GL_BLEND); } render() { Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT); Gdx.gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); // ... // bind texture and create vertices // ... } So the question is: How do I solve the transparency overlap problem?

  • 2D animations frames vs 3D animation for small indie project: timing considerations

    - by mm24
    pretty lame question but was wondering.. I am developing a 2D game using Cocos2D for iOS. The art work till now is all 2D (is a shooter game) but some of the characters would benefit of complex animations (eg. 20 frames). I feel a bit stupid because I came across only now that there is the chance to do 3D to 2D frames exporting and then to use them in Cocos2D. The thing that put me off on 3D gaming at first was that it takes more than one person in a team to do so properly (Illustrator, 3D modeller, 3D animator and programmer). Now I feel a bit stupid because having a 3D model I could do and modify the poses whenever I wanted (I should ask to the 3D animator which I guess would be time expensive). Instead now is me and two illustrators (as I require many frames per character). Is my impression that it would have been much longer right or not? Are there any other project management considerations that can be done on this? Sorry if for some this might be trivial but is my first "indie game developer experience".

  • Is there a way to legally create a game mod?

    - by Rodrigo Guedes
    Some questions about it: If I create a funny version of a copyrighted game and sell it (crediting the original developers) would it be considered a parody or would I need to pay royalties? If I create a game mod for my own personal use would it be legal? What if I gave it for free to a friend? Is there a general rule about it or it depends on the developer will? P.S.: I'm not talking about cloning games like this question. It's all about a game clearly based on another. Something like "GTA Gotham City" ;) EDIT: This picture that I found over the internet illustrate what I'm talking about: Just in case I was not clear: I never created a mod game. I was just wondering if it would be legally possible before trying to do it. I'm not apologizing piracy. I pay dearly for my games (you guys have no idea how expensive games are in Brazil due to taxes). Once more I say that the question is not about cloning. Cloning is copy something and try to make your version look like a brand new product. Mods are intended to make reference to one or more of its source. I'm not sure if it can be done legally (if I knew I wasn't asking) but I'm sure this question is not a duplicate. Even so, I trust in the moderators and if they close my question I will not be offended - at least I had an opportunity to explain myself and got 1 good answer (by the time I write this, maybe some more will be given later).

  • Should I have seperate business and personal websites?

    - by Thomas Clowes
    I have my business website - I am a web designer and developer, and also buy/sell websites/domain names. As such my website links to 'Our sites' = the websites which we design and run as well as a variety of tools such as a domain whois tool. These are obviously relevant to the business. As an individual, I like to travel and do white water kayaking as a hobby. I also have a degree in economics. I have thus created a blog on my business website where I write about domain names, web design, kayaking, travelling and economics. I've just begun researching SEO and am looking into optimizing my business website. I don't actually directly offer any services to clients at the moment, my main aim is to have a business website which supports my websites. If for example a potential advertise on one of my sites checks out the business website, I want them to think professional, down to earth, quirky. Given this is having my business/personal interests intertwined a problem? For SEO.. on my homepage for example when I'm writing a headline and a paragraph about what we do.. what do I put? and how do I optimize for SEO with keywords and the like? Further to the above, my company sponsors me and a group of accquantances as a kayaking team.. as such my personal interests do sort of overlap (just to add a complexity :))

  • Discount Multilingual Day in the Life of User Experience

    - by ultan o'broin
    Super article by the WikiMedia Foundation engineering folks about Designing for the Multilingual Web using the Wikipedia Universal Language Selector user interface as an example. Great ideas about tools that are available, as well as covering the basics of wireframing (mockups), prototyping, and user testing. Lots of inspiration there for developers and builders of apps who want to ensure their user experience (UX) really delivers for a global audience. Check out the use of the Firefox-based Pencil, how to translate your mockups, and how to perform remote user testing using Google+ Hangouts. Paul Giner demonstrates how to translate mockups. A little clunky and homespun in parts (I would prefer if tools such as Pencil or Balsamiq MockUps, and so on, could roundtrip directly from SVG to XLIFF for example, and Pencil doesn't work yet with the latest versions for Firefox) and I am not sure how it can really scales to enterprise-level use. However, the UX methodology is basically sound, and reinforces the importance of designing and testing in more that one language. The most powerful message for me is that you do not need special resources, training or expensive tools to deliver great-looking usable apps if you're a developer. Definitely worth considering if you're building apps out there in the community.

  • Questions about Code Reviews

    - by bamboocha
    My team plans to do Code Review and asked me to make a concept what and how we are going to make our Code Reviews. We are a little group of 6 team members. We use an SVN repository and write programs in different languages (mostly: VB.NET, Java, C#), but the reviews should be also possible for others, yet not defined. Basically I am asking you, how are you doing it, to be more precise I made a list of some questions I got: 1. Peer Meetings vs Ticket System? Would you tend to do meetings with all members, rather than something like a ticket system, where the developer can add a new code change and some or all need to check and approve it? 1. What tool? I made some researches on my own and it showed that Rietveld seems to be the program to use for non-git solutions. Do you agree/disagree and why? 2. A good workflow to follow? 3. Are there good ways to minimize the effort for those meetings even more? 4. What are good questions, every code reviewer should follow? I already made a list with some questions, what would you append/remove? are there any magic numbers in the code? do all variable and method names make sense and are easily understandable? are all querys using prepared statement? are all objects disposed/closed when they are not needed anymore? 5. What are your general experiences with it? What's important? Things to consider/prevent/watch out?

  • Cross platform development query

    - by Ian
    I'm a Microsoft developer mainly, but there are a couple of small-ish projects I'd like to fiddle with which would benefit from being cross platform. The platforms I want to target are: Windows, Linux, Mac, Android and preferably iPhone, web (running in a browser). I need 3D (Around the level of support seen in something like Minecraft (I'm not writing Minecraft)), some networking. I'm pretty certain Java would work on all except iPhone. Looking at the "related questions" above it's offered up QT (no browser or phone afaik) and also HTML/CSS/Javascript (3D? package for desktop?) The other alternative is to have seperate versions for seperate platforms, developed with some common code where possible. That option isn't something I know anything about. Does anyone have experience of this sort of conundrum? I figured here was better than SO, because I imagine there are compromises which extend beyond technical choice. Finally, this is not a commercial operation, so some of the very expensive cross platform tools are out of the question unless they offer some sort of community edition. Thanks for your time.

  • Why not have a High Level Language based OS? Are Low Level Languages more efficient?

    - by rtindru
    Without being presumptuous, I would like you to consider the possibility of this. Most OS today are based on pretty low level languages (mainly C/C++) Even the new ones such as Android uses JNI & underlying implementation is in C In fact, (this is a personal observation) many programs written in C run a lot faster than their high level counterparts (eg: Transmission (a bittorrent client on Ubuntu) is a whole lot faster than Vuze(Java) or Deluge(Python)). Even python compilers are written in C, although PyPy is an exception. So is there a particular reason for this? Why is it that all our so called "High Level Languages" with the great "OOP" concepts can't be used in making a solid OS? So I have 2 questions basically. Why are applications written in low level languages more efficient than their HLL counterparts? Do low level languages perform better for the simple reason that they are low level and are translated to machine code easier? Why do we not have a full fledged OS based entirely on a High Level Language?

  • Current SPARC Architectures

    - by Darryl Gove
    Different generations of SPARC processors implement different architectures. The architecture that the compiler targets is controlled implicitly by the -xtarget flag and explicitly by the -arch flag. If an application targets a recent architecture, then the compiler gets to play with all the instructions that the new architecture provides. The downside is that the application won't work on older processors that don't have the new instructions. So for developer's there is a trade-off between performance and portability. The way we have solved this in the compiler is to assume a "generic" architecture, and we've made this the default behaviour of the compiler. The only flag that doesn't make this assumption is -fast which tells the compiler to assume that the build machine is also the deployment machine - so the compiler can use all the instructions that the build machine provides. The -xtarget=generic flag tells the compiler explicitly to use this generic model. We work hard on making generic code work well across all processors. So in most cases this is a very good choice. It is also of interest to know what processors support the various architectures. The following Venn diagram attempts to show this: A textual description is as follows: The T1 and T2 processors, in addition to most other SPARC processors that were shipped in the last 10+ years supported V9b, or sparcvis2. The SPARC64 processors from Fujitsu, used in the M-series machines, added support for the floating point multiply accumulate instruction in the sparcfmaf architecture. Support for this instruction also appeared in the T3 - this is called sparcvis3 Later SPARC64 processors added the integer multiply accumulate instruction, this architecture is sparcima. Finally the T4 includes support for both the integer and floating point multiply accumulate instructions in the sparc4 architecture. So the conclusion should be: Floating point multiply accumulate is supported in both the T-series and M-series machines, so it should be a relatively safe bet to start using it. The T4 is a very good machine to deploy to because it supports all the current instruction sets.

  • Web.NET event coming in October

    - by Chris Massey
    If you’re a web developer in Europe (or would like an excuse to travel to Europe), you should definitely take a look at the Web.NET event coming in October. It’s being organized by two Italian web maestros (Simone Chiaretta and Ugo Lattanzi) and the session list looks fantastic. The event site pretty much speaks for itself, but here’s a quick version: It’s a free one-day event on October 20th, with a huge variety of great sessions by great speakers, all 100% focused on web development. There’s a pizza-fuelled hackathon in the evening; thrills, spills and hot new skills. It’s a great chance to network with the local (in relative terms) web development community. It’s free (although all donations are very greatly appreciated). It’s in Milan, darling. Here’s what you need to do: Go and register on www.webnetconf.eu, and vote on which sessions you think look the most interesting. I know this will be a difficult process – it’s *very* hard to choose – but persevere! Grab your place when the free tickets become available early next month (places are limited). Come to Milan in October, learn some new skills, meet some great people, and maybe build something awesome if you feel like staying up late. I’ll be there, and hopefully I’ll see you on the day.

  • Thick models Vs. Business Logic, Where do you draw the distinction?

    - by TokenMacGuy
    Today I got into a heated debate with another developer at my organization about where and how to add methods to database mapped classes. We use sqlalchemy, and a major part of the existing code base in our database models is little more than a bag of mapped properties with a class name, a nearly mechanical translation from database tables to python objects. In the argument, my position was that that the primary value of using an ORM was that you can attach low level behaviors and algorithms to the mapped classes. Models are classes first, and secondarily persistent (they could be persistent using xml in a filesystem, you don't need to care). His view was that any behavior at all is "business logic", and necessarily belongs anywhere but in the persistent model, which are to be used for database persistence only. I certainly do think that there is a distinction between what is business logic, and should be separated, since it has some isolation from the lower level of how that gets implemented, and domain logic, which I believe is the abstraction provided by the model classes argued about in the previous paragraph, but I'm having a hard time putting my finger on what that is. I have a better sense of what might be the API (which, in our case, is HTTP "ReSTful"), in that users invoke the API with what they want to do, distinct from what they are allowed to do, and how it gets done. tl;dr: What kinds of things can or should go in a method in a mapped class when using an ORM, and what should be left out, to live in another layer of abstraction?

  • Microsoft ADO.NET 4 Step by Step

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). Many years ago, I wrote Pro ADO.NET 2.0. I still think that in the plethora of new data access technologies that have come out since, the basic core ADO.NET fundamentals are still every developer must know, and sadly they do not know. So for some crazy reason, I still see every project make the same data access related mistakes over and over again. Anyway, the challenge is that on top of the core ADO.NET fundamentals, there is a vast array of other new technologies you must learn. The important of which is Entity Framework. So, I was asked to, and I was pleased to be the technical reviewer for Microsoft ADO.NET 4, Step by Step, by Tim Patrick. This book introduces the reader not just to the basic ADO.NET principles, but also Entity Framework, LINQ to SQL, and WCF Data Services. So what you may ask is a SharePoint guy like me doing with such interest in ADO.NET land? Well, that’s what the other side says, what is a hardcore data access sorta guy doing in SharePoint land? :). I have authored/co-authored 4 books so far on data access (1,2,3,4), and one on pure SharePoint, and now one on SharePoint 2010 BI. These are very intertwined topics. And LINQ to SQL and LINQ to SharePoint are almost copy paste of each other. WCF Data services are literally the same in both. And many Entity Framework concepts also apply within SharePoint. So there, I did these both for “interest” reasons. Comment on the article ....

  • Data migration - dangerous or essential?

    - by MRalwasser
    The software development department of my company is facing with the problem that data migrations are considered as potentially dangerous, especially for my managers. The background is that our customers are using a large amount of data with poor quality. The reasons for this is only partially related to our software quality, but rather to the history of the data: Most of them have been migrated from predecessor systems, some bugs caused (mostly business) inconsistencies in the data records or misentries by accident on the customer's side (which our software allowed by error). The most important counter-arguments from my managers are that faulty data may turn into even worse data, the data troubles may awake some managers at the customer and some processes on the customer's side may not work anymore because their processes somewhat adapted to our system. Personally, I consider data migrations as an integral part of the software development and that data migration can been seen to data what refactoring is to code. I think that data migration is an essential for creating software that evolves. Without it, we would have to create painful software which somewhat works around a bad data structure. I am asking you: What are your thoughts to data migration, especially for the real life cases and not only from a developer's perspecticve? Do you have any arguments against my managers opinions? How does your company deal with data migrations and the difficulties caused by them? Any other interesting thoughts which belongs to this topics?
