  • How could we rewrite the 'No Evil' license to make it 'free'?

    - by passcod
    I did not find the lawyers' SE site, so I thought it best to post here. /* * ...subject to the following conditions: * * The above copyright notice and this permission notice shall be included in all * copies or substantial portions of the Software. * * The Software shall be used for Good, not Evil. * * THE SOFTWARE IS PROVIDED "AS IS"... */ This is the 'non-free', Crockford, No-Evil, MIT-style, license. This license is considered non-free because of this phrase: "The Software shall be used for Good, not Evil." How could we rewrite this to become a 'free' license, while retaining the original spirit of the sentence?

  • Visual WebGui's XAML based programming for web developers

    - by Webgui
    While ASP.NET provides an event base approach it is completely dismissed when working with AJAX and the richness of the server is lost and replaced with JavaScript programming and couple with a very high security risk. Visual WebGui reinstates the power of the server to AJAX development and provides a statefull yet scalable, server centric architecture that provides the benefits and user productivity of AJAX with the security and developer productivity we had before AJAX stormed into our lives. "When I first came up with the concept of Visual WebGui , I was frustrated by the fragile and complex nature of developing web applications. The contrast in productivity between working in a fully OOP compiled environment vs. scripting even today, with JQuery, Dojo and such, is still huge. Even today the greatest sponsor of JavaScript programming, Google, is offering a framework to avoid JavaScript using Java that compiles to JavaScript (GWT). So I decided to find a way to abstract the complexity or rather delegate the complex job to enable developers to concentrate on the “What” instead of the “How” and embraced the Form based approach," said Guy Peled the inventor of Visual WebGui. Although traditional OOP development still rules the enterprise, the differences between web sites and web applications have blurred and so did the differences between classic developers and web developers. As a result, we now see declarative languages in desktop / backend development environments (WPF / WF) and we see OOP, gaining more and more power in web development (ASP.NET MVC / ASP.NET DOM). However, what has not changed is enterprise need for security, development ROI, reach, highly responsive and interactive UIs and scalability. The advantages that declarative languages and 'on demand' compilation provide over classic development are mostly the flexibility and a more readable initialize component it offers which is what Gizmox is aspiring to do by replacing the designer initialize component with XAML code. The code in this new project template will be compiled on demand using the build provider mechanism ASP.NET has. This means that the performance hit is only on the first request and after that the performance is the same as a prebuilt solution. This will allow the flexibility of a dynamically updated sites and the power of fully blown enterprise applications over web. You can also use prebuilt features available in ASP.NET to enjoy both worlds in production. VWG XAML implementation (VWG Sites) will be the first truly compliable XAML implementation as Microsoft implemented Silverlight and WPF as a runtime markup interpretation opposed to the ASP.NET markup implementation which is compiled to CLR code once. We have chosen to implement the VWG Sites parser as a different way to create CLR code that provides greater performance over the reflection alternative. VWG Sites will also be the first server side XAML UI engine which, while giving the power of XAML, it will not require any plug-ins or installations on the client side. Short demo video of VWG Sites markup. There is also a live sample available here.

  • Github Workflow: Pushing small fix branches to remote, or keep them local?

    - by Isaac Hodes
    In Scott Chacon's workflow (explained eg in this SO answer), with essentially two silos (development, and master), if, say I have a small bug to fix (e.g. can be fixed with a few characters) is the optimal way of doing that: a) branch off of development a branch called e.g. fix_123. Push this branch to origin as I work on it. When it's done, code-reviewed, whatever, merge into development and push development to origin. b) Same as above, but without pushing fix_123 to origin.

  • Stop trying to be perfect

    - by Kyle Burns
    Yes, Bob is my uncle too.  I also think the points in the Manifesto for Software Craftsmanship (manifesto.softwarecraftsmanship.org) are all great.  What amazes me is that tend to confuse the term “well crafted” with “perfect”.  I'm about to say something that will make Quality Assurance managers and many development types as well until you think about it as a craftsman – “Stop trying to be perfect”. Now let me explain what I mean.  Building software, as with building almost anything, often involves a series of trade-offs where either one undesired characteristic is accepted as necessary to achieve another desired one (or maybe stave off one that is even less desirable) or a desirable characteristic is sacrificed for the same reasons.  This implies that perfection itself is unattainable.  What is attainable is “sufficient” and I think that this really goes to the heart both of what people are trying to do with Agile and with the craftsmanship movement.  Simply put, sufficient software drives the greatest business value.   I've been in many meetings where “how can we keep anything from ever going wrong” has become the thing that holds us in analysis paralysis.  I've also been the guy trying way too hard to perfect some function to make sure that every edge case is accounted for.  Somewhere in there, something a drill instructor said while I was in boot camp occurred to me.  In response to being asked a question by another recruit having to do with some edge case (I can barely remember the context), he said “What if grasshoppers had machine guns?  Would the birds still **** with them?”  It sounds funny, but there's a lot of wisdom in those words.   “Sufficient” is different for every situation and it’s important to understand what sufficient means in the context of the work you’re doing.  If I’m writing a timesheet application (and please shoot me if I am), I’m going to have a much higher tolerance for imperfection than if you’re writing software to control life support systems on spacecraft.  I’m also likely to have less need for high volume performance than if you’re writing software to control stock trading transactions.   I’d encourage anyone who has read this far to instead of trying to be perfect, try to create software that is sufficient in every way.  If you’re working to make a component that is sufficient “better”, ask yourself if there is any component left that is not yet sufficient.  If the answer is “yes” you’re working on the wrong thing and need to adjust.  If the answer is “no”, why aren’t you shipping and delivering business value?

  • Default values - are they good or evil?

    - by Andrew
    The question about default values in general - default return function values, default parameter values, default logic for when something is missing, default logic for handling exceptions, default logic for handling the edge conditions etc. For a long time I considered default values to be a "pure evil" thing, something that "cloaks the catastrophe" and results in a very hard do find bugs. But recently I started to think about default values as some sort of a technical debt ... which is not a straight bad thing but something that could provide some "short term financing" get us to survive the project (how many of us could afford to buy a house without taking out the mortgage?). When I say a "short term" - I don't mean - "do something quickly first and do refactor it out later before it hits the production". No - I am talking about relying on a hardcoded default values in a production software. Granted - it could cause some issues, but what if it only going to cause a single trouble in a whole year. Again - I am talking about the "average" mainstream software here (not a software for a nuclear power station) - the average web site or a UI application for the accounting software, meaning that people lives are not at stake, nor millions of dollars. Again, from my experience, business users would rather live with the software which "works somehow", rather then wait for a perfect one. And the use of default values helps a lot if you develop a software in a RAD style. But again - the longest debug sessions I have spent were because of the bugs introduced by a default value which either stopped being "a default" along the way or because a small subsystem has recently been upgraded and as a result of this upgrade it does not handle the default correctly (e.g. empty list vs null, or null string vs empty string). So my question is - are the default values good or evil. And if they are a technical debt - how do measure up how much you can borrow so you can afford the repayments? Would really appreciate any input. Cheers. EDIT: If I am using the default values as a way to cut the corners during the development - and if the corners cutting results in a bugs and issues - what is the methodology to recover from these issues?

  • Book: DevOps for Developers

    - by Tori Wieldt
    We all know development and operations often act like silos, with "Just throw it over the wall!" being the battle cry. Many organizations unwittingly contribute to gaps between teams, with management by (competing) objectives; a clash of Agile practices vs. more conservative approaches; and teams using different sets of tools, such as Nginx, OpenEJB, and Windows on developers' machines and Apache, Glassfish, and Linux on production machines. At best, you've got sub-optimal collaboration, at worst, you've got the Hatfields and the McCoys.  The book DevOps for Developers helps bridge the gap between development and operations by aligning incentives and sharing approaches for processes and tools. It introduces DevOps as a modern way of bringing development and operations together. It also means to broaden the usage of Agile practices to operations to foster collaboration and streamline the entire software delivery process in a holistic way. Some single aspects of DevOps may not be new, for example, you may have used the tool Puppet for years already, but with a new mindset ("my job is not just to code, it's to serve the customer in the best way possible") and a complete set of recipes, you'll be well on your way to success. DevOps for Developers also by provides real-world use cases (e.g., how to use Kanban or how to release software). It provides a way to be successful in the real development/operations world. DevOps for Developers is written my Michael Hutterman, Java Champion, and founder of the Cologne Java User Group. "With DevOps for Developers, developers can learn to apply patterns to improve collaboration between development and operations as well as recipes for processes and tools to streamline the delivery process," Hutterman explains.

  • Comparison of languages by usage type?

    - by Tom
    Does anyone know of a good place to go find comparisons of programming languages by the intended platform/usage? Basically, what I want to know, is of the more popular languages, which ones are meant for high level application development, low level system development, mobile development, web, etc. If there's a good listing out there already, I'm not finding it so far. Does anyone know of a place that would have this? Thanks.

  • The Iron Bird Approach

    - by David Paquette
    It turns out that designing software is not so different than designing commercial aircraft.  I just finished watching a video that talked about the approach that Bombardier is taking in designing the new C Series aircraft.  I was struck by the similarities to agile approaches to software design.  In the video, Bombardier describes how they are using an Iron Bird to work through a number of design questions in advance of ever having a version of the aircraft that can ever be flown.  The Iron Bird is a life size replica of the plane.  Based on the name, I would assume the plane is built in a very heavy material that could never fly.  Using this replica, Bombardier is able to valid certain assumptions such as the length of each wire in the electric system.  They are also able to confirm that some parts are working properly (like the rudders).  They even go as far as to have a complete replica of the cockpit.  This allows Bombardier to put pilots in the cockpit to run through simulated take-off and landing sequences. The basic tenant of the approach seems to be Validate your design early with working prototypes Get feedback from users early, well in advance of finishing the end product   In software development, we tend to think of ourselves as special.  I often tell people that it is difficult to draw comparisons to building items in the physical world (“Building software is nothing like building a sky scraper”).  After watching this video, I am wondering if designing/building software is actually a lot like designing/building commercial aircraft.   Watch the video here (http://www.theglobeandmail.com/report-on-business/video/video-selling-the-c-series/article4400616/)

  • Best Language for the job? Database | C++, .NET, Java

    - by Randy E
    Ok, quick overview. I'm pretty brand new to software design. I have experience reading and editing/customizing PHP things for online scripts/software; Such as CMS, Wordpress, some forum solutions. I'm about to begin my degree in Software Design, the school I'm going to will allow us to kind of focus on an area, C++, Java, or .NET. I've played around a little with VB over the past week, mostly just trying to get a slight feel for it, however nothing extensive. I've been through Herbert Schildt's "C++, A Beginner's Guide." but I was mainly reading it, not doing anything with it beyond a couple basic Console Apps (and getting frustrated with auto-close :/ ). Now, where I decide to focus more in with my degree will depend on what the best language for the job is for my first piece of software I want to develop on my own. Assume I haven't looked at any of the languages at all, please help with the following: My first piece of software will be a database program. Everything has to do with users inputting and retrieving data, and calling that data to help with another function of the software, automatically calculating billing information based on information inputted in the other portion of the program. I won't go into too many details as I'm targeting a niche that doesn't have too much competition, but the competition that is there is established. I want to offer more features, scalable solutions, and the ability to port it to an online version. Ok, basically, it is a complete case management with integrated billing for Private Investigators. I would like the case management to be able to check the Database to see if certain information has been inputted before (such as Names/SSN's), and then the billing will pull hours inputted in the case portion for investigative work, multiplying by an already inputted amount for the fee, and then calculate sales tax. I also want to provide potential clients with an easily scalable solution, that is, a basic option for start ups that costs the least amount, with no additional users, ran on one machine. A middle option with the ability to create users and place them in two groups (User or Admin), as well as adding a few additional features, ran on one machine, but this will allow it to be accessed after being mapped on a network drive. And a third option to allow the placement into 4 different groups (Investigators, Billing, Managers, Admins) and more features. And then, a couple of years after launch, a 4th option that is browser based allowing the same 4 groups to login, as well as clients (view things concerning their case, with some admin customizable objects that can be added for clients view), over the internet. The only licensing security I would like to employ right off the bat will be serial key generated after ordering online (received in an email after the successful purchase). The program will access a database stored on a server periodically to verify license. I would like it to be able to check to make sure it's the most updated version and automatically update if not.

  • Are there serious companies that don't use version-control and continuous integration? Why?

    - by daramarak
    A colleague of mine was under the impression that our software department was highly advanced, as we used both a build server with continuous integration, and version control software. This did not match my point of view, as I only know of one company I which made serious software and didn't have either. However, my experience is limited to only a handful of companies. Does anyone know of any real company (larger than 3 programmers), which is in the software business and doesn't use these tools? If such a company exists, are there any good reason for them not doing so?

  • Calling all developers building ASP.NET applications

    - by Laila Lotfi
    We know that developers building desktop apps have to contend with memory management issues, and we’d like to learn more about the memory challenges ASP.NET developers are facing. To be more specific, we’re carrying out some exploratory research leading into the next phase of development on ANTS Memory Profiler, and our development team would love to speak to developers building ASP.NET applications. You don’t need to have ever used ANTS profiler – this will be a more general conversation about: - your current site architecture, and how you manage the memory requirements of your applications on your back-end servers and web services. - how you currently diagnose memory leaks and where you do this (production server, or during testing phase, or if you normally manage to get them all during the local development). - what specific memory problems you’ve experienced – if any. Of course, we’ll compensate you for your time with a $50 Amazon voucher (or equivalent in other currencies), and our development team’s undying gratitude. If you’d like to participate, please just drop me a line on [email protected].

  • Verfication vs validation again, does testing belong to verification? If so, which?

    - by user970696
    I have asked before and created a lot of controversy so I tried to collect some data and ask similar question again. E.g. V&V where all testing is only validation: http://www.buzzle.com/editorials/4-5-2005-68117.asp According to ISO 12207, testing is done in validation: •Prepare Test Requirements,Cases and Specifications •Conduct the Tests In verification, it mentiones. The code implements proper event sequence, consistent interfaces, correct data and control flow, completeness, appropriate allocation timing and sizing budgets, and error definition, isolation, and recovery. and The software components and units of each software item have been completely and correctly integrated into the software item Not sure how to verify without testing but it is not there as a technique. From IEEE: Verification: The process of evaluating software to determine whether the products of a given development phase satisfy the conditions imposed at the start of that phase. [IEEE-STD-610]. Validation: The process of evaluating software during or at the end of the development process to determine whether it satisfies specified requirements. [IEEE-STD-610] At the end of development phase? That would mean UAT.. So the question is, what testing (unit, integration, system, uat) will be considered verification or validation? I do not understand why some say dynamic verification is testing, while others that only validation. An example: I am testing an application. System requirements say there are two fields with max. lenght of 64 characters and Save button. Use case say: User will fill in first and last name and save. When checking the fields and Save button presence, I would say its verification. When I follow the use case, its validation. So its both together, done on the system as a whole.

  • Which programming career path fits my terms? [closed]

    - by Goward Gerald
    I am sick and tired of my enterprise development job, I need some programming direction like this: Demanded in jobs-market Demanded in freelance market Can use Ubuntu as development environment Not enterprise. Standalone, mobile, web-development, anything, just not enterprise. Basically, I need a programming direction which doesn't need 20 developers, terribly big databases systems and long going projects with intense long-term support, I don't want enterprise job where a lot of people are working on one terribly big project and do modules to it all day long. Instead, I need something where: Projects change pretty often Projects are little, or medium-sized (in terms of code, modules and people working on it) but still not enterprise-sized Possible for freelance, solo-development, or at least requires a team of 3-4 programmers. Not like in enterprise where you feel like a drop in the sea with your 50 classes while system itself has hundreds of classes. Suggestions please?
