  • 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?

  • Add Events to Windows Live Calendar in IE 8

    - by Asian Angel
    Do you have event dates that you need to make note of while browsing in Internet Explorer? Adding those events to your Live Calendar is easy to do with the Add Events to Windows Live Calendar accelerator. Adding Events to your Live Calendar To add the accelerator click on Add to Internet Explorer and then confirm the installation when the secondary window appears. For our example we chose the “estimated” availability date of Microsoft Office 2010 to the public. At the bottom of the pre-order page we found the date we were looking for. To add an event highlight the desired text (will become event description) and select the Add an Event to Windows Live Calendar listing in the context menu. A new tab will be opened where you can add any relevant details or make final tweaks to the description before saving the event. There is our new calendar event ready to send out a notification e-mail for the Office 2010 release. The Add Events to Windows Live Calendar accelerator speeds up the process of adding events to your calendar by getting you directly to the event form.

  • how to make HLSL effect just for lighning without texture mapping?

    - by naprox
    I'm new to XNA, i created an effect and just want to use lightning but in default effect that XNA create we should do texture mapping or the model appears 'RED', because of this lines of code in the effect file: float4 PixelShaderFunction(VertexShaderOutput input) : COLOR0 { float4 output = float4(1,0,0,1); return output; } and if i want to see my model (appear like when i use basiceffect) must do texture mapping by UV coordinates. but my model does not have UV coordinates assigned or its UV coordinates is not exported. and if i do texture mapping i got error. (i do texture mapping by this line of code in vertexshaderfunction and other necessary codes) output.UV= input.UV i have many of this models and want to work with them.(my models are in .FBX format) when i use Bassiceffect i have no problem and model appears correctly. how can i use "just" lightnings in my custom effects? and don't do texture mapping (because i have no UV coordinates in my models) and my model be look like when i use BasicEffect? if you need my complete code Here it is: http://www.mediafire.com/?4jexhd4ulm2icm2 here is inside of my Model Using BasicEffect http://i.imgur.com/ygP2h.jpg?1 and this is my code for drawing with or without BasicEffect inside of my draw() method: Matrix baseWorld = Matrix.CreateScale(Scale) * Matrix.CreateFromYawPitchRoll(Rotation.Y, Rotation.X, Rotation.Z) * Matrix.CreateTranslation(Position); foreach(ModelMesh mesh in Model.Meshes) { Matrix localWorld = ModelTransforms[mesh.ParentBone.Index] * baseWorld; foreach(ModelMeshPart part in mesh.MeshParts) { Effect effect = part.Effect; if (effect is BasicEffect) { ((BasicEffect)effect).World = localWorld; ((BasicEffect)effect).View = View; ((BasicEffect)effect).Projection = Projection; ((BasicEffect)effect).EnableDefaultLighting(); } else { setEffectParameter(effect, "World", localWorld); setEffectParameter(effect, "View", View); setEffectParameter(effect, "Projection", Projection); setEffectParameter(effect, "CameraPosition", CameraPosition); } } mesh.Draw(); } setEffectParameter is another method that sets effect parameter if i use my custom effect.

  • What's a good entity hierarchy for a 2D game?

    - by futlib
    I'm in the process of building a new 2D game out of some code I wrote a while ago. The object hierarchy for entities is like this: Scene (e.g. MainMenu): Contains multiple entities and delegates update()/draw() to each Entity: Base class for all things in a scene (e.g. MenuItem or Alien) Sprite: Base class for all entities that just draw a texture, i.e. don't have their own drawing logic Does it make sense to split up entities and sprites up like that? I think in a 2D game, the terms entity and sprite are somewhat synonymous, right? But I do believe that I need some base class for entities that just draw a texture, as opposed to drawing themselves, to avoid duplication. Most entities are like that. One weird case is my Text class: It derives from Sprite, which accepts either the path of an image or an already loaded texture in its constructor. Text loads a texture in its constructor and passes that to Sprite. Can you outline a design that makes more sense? Or point me to a good object-oriented reference code base for a 2D game? I could only find 3D engine code bases of decent code quality, e.g. Doom 3 and HPL1Engine.

  • The Silverlight 4 Training Kit and Green Eggs &amp; Ham

    - by Jim Duffy
    Microsoft has released the Silverlight 4 Training Kit that steps you through the process of constructing Silverlight 4 business applications. “The Silverlight 4 Training Course includes a whitepaper explaining all of the new Silverlight 4 features, several hands-on-labs that explain the features, and a 8 unit course for building business applications with Silverlight 4. The business applications course includes 8 modules with extensive hands on labs as well as 25 accompanying videos that walk you through key aspects of building a business application with Silverlight. Key aspects in this course are working with numerous sandboxed and elevated out of browser features, the new RichTextBox control, implicit styling, webcam, drag and drop, multi touch, validation, authentication, MEF, WCF RIA Services, right mouse click, and much more!” What I think is pretty cool is that there are two ways to access this content, online and offline. Obviously the online version is great when you’re sitting at your desk and you’re connected to the web. What about when you don’t have a connection like when you’re located where you won’t eat green eggs & ham, like on a train or on plane perhaps? :-) You can download the offline version and hope that Sam I Am won’t be to distracting while you try to watch the videos or work your way through the labs. :-) Have a day. :-|

  • Commercial product using a GPL OS

    - by pfried
    we are planning to create a commercial product. The product consists of come MCUs and a small computer (we are developping on a raspberry pi at the moment). The computer needs an operating system as we would like keep things like WLAN and booting as simple as possible. We create some software running on this computer (node.js application). The most operating systems like Arch Linux are licenced under the GPL. The product we would sell contains the computer with preinstalled OS and software. This system operates as a central access point to MCU devices and is able to control them. We use other's software in our product. We do not modify their source code. The product (the computer part) consists of a computer, an OS and software we create. How does the use of an OS affect our own code (licence)? Is there a possibility of avoiding GPL for our own code? eg. shipping the software seperated? Are there any effects to other components of our product, eg. the MCU part? The node.js application delivers a WebApp to the client where it is executed. Are there any effects (As we would like to sell parts of the code as an additional App on the App Stores)? I know we make use of the work of the community and i respect this. The problem is: The software alone is kind of useless without the MCU devices. I do not expect a legal advice.

  • Syncing sharepoint 2010 with outlook

    - by uruit
    Technorati Tags: Sharepoint 2010,Outlook SharePoint offers the possibility to connect to content in a Document Library directly from Outlook, edit the documents offline and then sync when connection is restored. This is very useful if we are working at home and we want to access a shared document (ex. VPN connection settings) or continue working directly on a file. Steps to configure the connection: 1. Browse online to SharePoint Document library you want to connect and click on "Connect to Outlook": (click to enlarge) 2. Click Allow to confirm: 3. In Outlook you will see the documents as outlook email items with the ability to preview them. When a document is updated, Outlook will notify you that you have items unread. If you want to edit a file, the corresponding office tool (Word, Excel, PowerPoint) will ask if you want to update the server after saving a change, it is really straightforward. (click to enlarge) 4. Finally, I recommend to add the IP address of your SharePoint server in the secure sites in order to prevent Outlook to ask for your windows credentials every time you open Outlook: (click to enlarge) Outlook is a great tool, letting you work in a really integrated way, don't miss this amazing feature. This feature is also available in SharePoint Online :)   Post by: Marcelo Martinez UruIT (www.uruit.com/sharepoint_outsourcing.html) Leaders in Nearshore Outsourcing from South America

  • Bomberman clone, how to do bombs?

    - by hustlerinc
    I'm playing around with a bomberman clone to learn game-developement. So far I've done tiles, movement, collision detection, and item pickup. I also have pseudo bombplacing (just graphics and collision, no real functionality). I've made a jsFiddle of the game with the functionality I currently have. The code in the fiddle is very ugly though. Scroll past the map and you find how I place bombs. Anyway, what I would like to do is an object, that has the general information about bombs like: function Bomb(){ this.radius = player.bombRadius; this.placeBomb = function (){ if(player.bombs != 0){ // place bomb } } this.explosion = function (){ // Explosion } } I don't really know how to fit it into the code though. Everytime I place a bomb, do I do var bomb = new Bomb(); or do i need to constantly have that in the script to be able to access it. How does the bomb do damage? Is it as simple as doing X,Y in all directions until radius runs out or object stops it? Can I use something like setTimeout(bomb.explosion, 3000) as timer? Any help is appreciated, be it a simple explanation of the theory or code examples based on the fiddle. When I tried the object way it breaks the code.

  • What can you do to decrease the number of live issues with applications?

    - by User Smith
    First off I have seen this post which is slightly similar to my question. : What can you do to decrease the number of deployment bugs of a live website? Let me layout the situation for you. The team of programmers that I belong to have metrics associated with our code. Over the last several months our errors in our live system have increased by a large amount. We require that our updates to applications be tested by at least one other programmer prior to going live. I personally am completely against this as I think that applications should be tested by end users as end users are much better testers than programmers, I am not against programmers testing, obviously programmers need to test code, but they are most of the times too close to the code. The reason I specify that I think end users should test in our scenario is due to the fact that we don't have business analysts, we just have programmers. I come from a background where BAs took care of all the testing once programmers checked off it was ready to go live. We do have a staging environment in place that is a clone of the live environment that we use to ensure that we don't have issues between development and live environments this does catch some bugs. We don't do end user testing really at all, I should say we don't really have anyone testing our code except programmers, which I think gets us into this mess (Ideally, we would have BAs or QA or professional testers test). We don't have a QA team or anything of that nature. We don't have test cases for our projects that are fully laid out. Ok, I am just a peon programmer at the bottom of the rung, but I am probably more tired of these issues than the managers complaining about them. So, I don't have the ability to tell them you are doing it all wrong.....I have tried gentle pushes in the correct direction. Any advice or suggestions on how to alleviate this issue is greatly appreciated. Thanks.

  • Ubuntu 11.10 power management does not recognize removal of power supply!

    - by sema
    I have a Lenovo Ideapad Z370 with Ubuntu 11.10 and the battery status indicator shows wrong information. Problem: The indicator always shows that the power supply is connected, even if it's not connected. The battery charges and discharges normally. However, the status information is wrong. When charging, the "time to charge" decreases, and when discharging the "time to charge" increases. If the power supply is connected the power statistics show: "Supply Yes" "Online Yes" If it is not connected it shows: "Supply Yes" "Online No" My trials: I tried reinstalling the indicator applet, but that doesn't help. Searching for solutions or similar problems didn't point out any help. Background: The problem occured after I switched the battery mode in Windows. (I use a dual boot system.) Lenovo drivers allow a "battery runtime mode" for maximum runtime and a "battery health mode" for maximum battery lifetime. I initially used the runtime mode, tried the health mode for some time, but switched back to the runtime mode. The problem occured after switching to health mode. Does anyone have an idea what is wrong? The problem is relevant for me as I get no information when battery status low and the computer runs out of energy without shutdown or hibernation. This is really a problem for me!

  • How-to get the binding for a tab in the Dynamic Tab Shell Template

    - by Frank Nimphius
    The Dynamic Tab Shell template does expose a method on the Tab.java class that allows you to get access to the ADF binding container for a tab. At least in theory this works, because in practice this call always returns a null value (a bug is filed for this). To work around the problem, you can use code similar to the following to get the ADF binding for a specific tab DCBindingContainer currentBinding = (DCBindingContainer) BindingContext.getCurrent().getCurrentBindingsEntry(); DCBindingContainer templateBinding = (DCBindingContainer)currentBinding.get("ptb1"); DCBindingContainer tabBinding= (DCBindingContainer)templateBinding.get("r"+0);  In the code line above, the tabBinding variable will hold the binding reference to the first tab in the dynamic tab shell template. Note that the tab doesn't need to be visible for this (which has to do with how the template works).  "ptb1" is the template reference name in the PageDef file (Executable section) of the template consumer view. Check this string in your page before using this code. If it differs, change it also in the code above. "r0" is the binding reference of the first tab in the template. Te last tab is referenced by "r14".

  • Fujitsu Raku-Raku SmartPhone: Japanese Digital Seniors UX Insight from @debralilley

    - by ultan o'broin
    Super blog posting on the super-important subject of digital inclusion by Oracle partner Fujitsu appstech maven and Oracle Applications User Experience FXA-er and ACE Director Debra Lilley (@debralilley). Debra tells us how Fujitsu is enabling digital inclusion for older mobile users in Japan with their  Raku-Raku (??????. ????)smart phone: Fujitsu Raku-Raku - My UX Homework (Raku-Raku means easy or comfortable in Japanese). There are UX mobile, social media, and methodology takeaways there for us in Debra's blog. Fujitsu Raku-Raku Smartphone Demo  I encourage you to read Debra's blog. In it, she makes reference to a tailored social media experience for those digital seniors (???????) as they'd be called in Japan (UK and Ireland uses the term silver surfers). You can find that online experience here. Online Community site for Fujitsu Raku-Raku Smartphone Digital Seniors (English translation via Google Translate) It's an important reminder that UX is global sure, but also that worldwide accessibility and digital inclusion are priorities too for UX. It's vital that we understand such aspects of technology adoption and how the requirements of different categories of technology users can be met. Oracle is committed to providing the best possible user experience for enterprise users of all ages and abilities. That means talking with all sorts of people worldwide and understanding how and why they want to use our technology and what their context of use is. You can read more about Oracle's accessibility program on our corporate website. Proud to say I prompted a few questions in Japan all the way from Ireland. So, UX is not only global but you can drive UX research globally too without ever leaving home. Brilliant job, Debra. Here's to more such joint research creativity and UX collaborations worldwide between us. Wondering where we might go next? And what a fun way to do things too!

  • Antenna Aligner part 2: Finding the right direction

    - by Chris George
    Last time I managed to get "my first app(tm)" built, published and running on my iPhone. This was really cool, a piece of my code running on my very own device. Ok, so I'm easily pleased! The next challenge was actually trying to determine what it was I wanted this app to do, and how to do it. Reverting back to good old paper and pen, I started sketching out designs for the app. I knew I wanted it to get a list of transmitters, then clicking on a transmitter would display a compass type view, with an arrow pointing the right way. I figured there would not be much point in continuing until I know I could do the graphical part of the project, i.e. the rotating compass, so armed with that reasoning (plus the fact I just wanted to get on and code!), I once again dived into visual studio. Using my friend (google) I found some example code for getting the compass data from the phone using the PhoneGap framework. // onSuccess: Get the current heading // function onSuccess(heading) {    alert('Heading: ' + heading); } navigator.compass.getCurrentHeading(onSuccess, onError); Using the ripple mobile emulator this showed that it was successfully getting the compass heading. But it didn't work when uploaded to my phone. It turns out that the examples I had been looking at were for PhoneGap 1.0, and Nomad uses PhoneGap 1.4.1. In 1.4.1, getCurrentHeading provides a compass object to onSuccess, not just a numeric value, so the code now looks like // onSuccess: Get the current magnetic heading // function onSuccess(heading) {    alert('Heading: ' + heading.magneticHeading); }; navigator.compass.getCurrentHeading(onSuccess, onError); So the lesson learnt from this... read the documentation for the version you are actually using! This does, however, lead to compatibility problems with ripple as it only supports 1.0 which is a real pain. I hope that the ripple system is updated sometime soon.

  • How to REALLY start thinking in terms of objects?

    - by Mr Grieves
    I work with a team of developers who all have several years of experience with languages such as C# and Java. Most of them are young enough to have been shown OOP as a standard way to develop software in university and are very comfortable with concepts such as inheritance, abstraction, encapsulation and polymorphism. Yet, many of them, and I have to include myself, still tend to create classes which are meant to be used in a very functional fashion. The resulting software is often several smaller classes which correctly represent business objects which get passed through larger classes which only supply ways to modify and use those objects (functions). Large complex difficult-to-maintain classes named Manager are usually the result of such behaviour. I can see two theoretical reasons why people might write this type of code: It's easy to start thinking of everything in terms of the database Deep down, for me, a computer handling a web request feels more like a functional operation than an object oriented operation when you think about Request Handlers, Threads, Processes, CPU Cores and CPU operations... I want source code which is easy to read and easy to modify. I have seen excellent examples of OO code which meet these objectives. How can I start writing code like this? How I can I really start thinking in an object oriented fashion? How can I share such a mentality with my colleagues?

  • Android Game Development problem with Speed = Distance / Time

    - by Charlton Santana
    I have been coding speed for an object. I have made it so the object will move from one end of the screen to another at a speed depending on the screen size, at the monemt I have made it so it will take one second to pass the screen. So i have worked out the speed in code but when I go to assign the speed it tells me to force close and i do not understand why. Here is the code: MainGame Code: @Override protected void onDraw(Canvas canvas) { setBlockSpeed(getWidth()); } private int blockSpeed; private void setBlockSpeed(int screenWidth){ Log.d(TAG, "screenWidth " + screenWidth); blockSpeed = screenWidth / 100; // 100 is the FPS.. i want it to take 1 second to pass the screen Math.round(blockSpeed); // to make it a whole number block.speed = blockSpeed; // this is line 318!! if i put eg block.speed = 8; it still tells me to force close } Block.java Code: public int speed; public void draw(Canvas canvas) { canvas.drawBitmap(bitmap, x - (bitmap.getWidth() / 2), y - (bitmap.getHeight() / 2), null); if(dontmove == 0){ this.x -= speed; // if it was eg this.x -= 18; it would not have an error } } The exception 06-08 13:22:34.315: E/AndroidRuntime(2801): FATAL EXCEPTION: Thread-11 06-08 13:22:34.315: E/AndroidRuntime(2801): java.lang.NullPointerException 06-08 13:22:34.315: E/AndroidRuntime(2801): at com.charltonsantana.game.MainGame.setBlockSpeed(MainGame.java:318) 06-08 13:22:34.315: E/AndroidRuntime(2801): at com.charltonsantana.game.MainGame.onDraw(MainGame.java:351) 06-08 13:22:34.315: E/AndroidRuntime(2801): at com.charltonsantana.game.MainThread.run(MainThread.java:64)

  • Using PreApplicationStartMethod for ASP.NET 4.0 Application to Initialize assemblies

    - by ChrisD
    Sometimes your ASP.NET application needs to hook up some code before even the Application is started. Assemblies supports a custom attribute called PreApplicationStartMethod which can be applied to any assembly that should be loaded to your ASP.NET application, and the ASP.NET engine will call the method you specify within it before actually running any of code defined in the application. Lets discuss how to use it using Steps : 1. Add an assembly to an application and add this custom attribute to the AssemblyInfo.cs. Remember, the method you speicify for initialize should be public static void method without any argument. Lets define a method Initialize. You need to write : [assembly:PreApplicationStartMethod(typeof(MyInitializer.InitializeType), "InitializeApp")] 2. After you define this to an assembly you need to add some code inside InitializeType.InitializeApp method within the assembly. public static class InitializeType {     public static void InitializeApp()     {           // Initialize application     } } 3. You must reference this class library so that when the application starts and ASP.NET starts loading the dependent assemblies, it will call the method InitializeApp automatically. Warning Even though you can use this attribute easily, you should be aware that you can define these kind of method in all of your assemblies that you reference, but there is no guarantee in what order each of the method to be called. Hence it is recommended to define this method to be isolated and without side effect of other dependent assemblies. The method InitializeApp will be called way before the Application_start event or even before the App_code is compiled. This attribute is mainly used to write code for registering assemblies or build providers. Read Documentation I hope this post would come helpful.

  • What is the precise definition of programming paradigm?

    - by Kazark
    Wikipedia defines programming paradigm thus: a fundamental style of computer programming which is echoed in the descriptive text of the paradigms tag on this site. I find this a disappointing definition. Anyone who knows the words programming and paradigm could do about that well without knowing anything else about it. There are many styles of computer programming at many level of abstraction; within any given programming paradigm, multiple styles are possible. For example, Bob Martin says in Clean Code (13), Consider this book a description of the Object Mentor School of Clean Code. The techniques and teachings within are the way that we practice our art. We are willing to claim that if you follow these teachings, you will enjoy the benefits that we have enjoyed, and you will learn to write code that is clean and professional. But don't make the mistake of thinking that we are somehow "right" in any absolute sense. Thus Bob Martin is not claiming to have the correct style of Object-Oriented programming, even though he, if anyone, might have some claim to doing so. But even within his school of programming, we might have different styles of formatting the code (K&R, etc). There are many styles of programming at many levels. So how can we define programming paradigm rigorously, to distinguish it from other categories of programming styles? Fundamental is somewhat helpful, but not specific. How can we define the phrase in a way that will communicate more than the separate meanings of each of the two words—in other words, how can we define it in a way that will provide additional meaning for someone who speaks English but isn't familiar with a variety of paradigms?

  • AsyncBridge? Async on .NET 4.0 using VS11

    - by Alex.Davies
    I've just found something quite cool. It's a code snippet that lets you use the real VS 11 C#5 compiler to write code that uses the async and await keywords, but to target .NET 4.0. It was published by Daniel Grunwald (from SharpDevelop).That means I can stop using the Async CTP for VS2010, which is not at all supported anymore, and a pain to install if you have windows updates turned on. Obviously I couldn't ask all my users to install .NET 4.5 beta, but .NET Demon is a VS 2010 extension, so we already have .NET 4.0. At the time of writing, VS11 is in beta still, but hopefully it's stable enough for my team to use!I would have written the code myself, but I had the wrong impression that the C# 5 beta compiler only looked in mscorlib for the helper classes it needs to implement async methods. Turns out you can provide them yourself. You can get the code here: https://gist.github.com/1961087You just add it to your project, and the compiler will apparently pick it up and use it to implement async/await. I'm at my parents' place for Easter without access to a machine with VS 11 to try it out. Let me know whether you get it to work!This reminds me of LINQBridge, which let us use C# 3 LINQ, but only require .NET 2. We should stick up a webpage to explain, with a nice easy dll, put it in nuget, and call it AsyncBridge.If you were really enthusiastic, you could re-implement the skeleton of the Task Parallel Library against .NET 2 to use async/await without even requiring .NET 4. Our usage stats suggest that practically everyone that uses Red Gate tools already has .NET 4 installed though, so I don't think I'll go to the effort.

  • An Interview with JavaOne Rock Star Martijn Verburg

    - by Janice J. Heiss
    An interview with JavaOne Rock Star Martijn Verburg, by yours truly, titled “Challenging the Diabolical Developer: A Conversation with JavaOne Rock Star Martijn Verburg,” is now up on otn/java. Verburg, one of the leading movers and shakers in the Java community, is well known for his ‘diabolical developer” talks at JavaOne where he uncovers some of the worst practices that Java developers are prone to. He mentions a few in the interview: * “A lack of communication: Software development is far more a social activity than a technical one; most projects fail because of communication issues and social dynamics, not because of a bad technical decision. Sadly, many developers never learn this lesson.* No source control: Some developers simply store code in local file systems and e-mail the code in order to integrate their changes; yes, this still happens.* Design-driven design: Some developers are inclined to cram every design pattern from the Gang of Four (GoF) book into their projects. Of course, by that stage, they've actually forgotten why they're building the software in the first place.” He points to a couple of core assumptions and confusions that lead to trouble: “One is that developers think that the JVM is a magic box that will clean up their memory and make their code run fast, as well as make them cups of coffee. The JVM does help in a lot of cases, but bad code can and will still lead to terrible results! The other trend is to try to force Java (the language) to do something it's not very good at, such as rapid Web development. So you get a proliferation of overly complex frameworks, libraries, and techniques trying to get around the fact that Java is a monolithic, statically typed, compiled, OO environment. It's not a Golden Hammer!” Verburg has many insightful things to say about how to keep a Java User Group (JUG) going, about the “Adopt a JSR” program, bugathons, and much more.

  • What can be done to decrease the number of live issues with applications?

    - by User Smith
    First off I have seen this post which is slightly similar to my question. : What can you do to decrease the number of deployment bugs of a live website? Let me layout the situation for you. The team of programmers that I belong to have metrics associated with our code. Over the last several months our errors in our live system have increased by a large amount. We require that our updates to applications be tested by at least one other programmer prior to going live. I personally am completely against this as I think that applications should be tested by end users as end users are much better testers than programmers, I am not against programmers testing, obviously programmers need to test code, but they are most of the times too close to the code. The reason I specify that I think end users should test in our scenario is due to the fact that we don't have business analysts, we just have programmers. I come from a background where BAs took care of all the testing once programmers checked off it was ready to go live. We do have a staging environment in place that is a clone of the live environment that we use to ensure that we don't have issues between development and live environments this does catch some bugs. We don't do end user testing really at all, I should say we don't really have anyone testing our code except programmers, which I think gets us into this mess (Ideally, we would have BAs or QA or professional testers test). We don't have a QA team or anything of that nature. We don't have test cases for our projects that are fully laid out. Ok, I am just a peon programmer at the bottom of the rung, but I am probably more tired of these issues than the managers complaining about them. So, I don't have the ability to tell them you are doing it all wrong.....I have tried gentle pushes in the correct direction. Any advice or suggestions on how to alleviate this issue ?

  • How do you explain to an "agile" team that they still need to plan the software they write?

    - by user23157
    This week at work I got agiled yet again. Having gone through the standard agile, TDD, shared ownership, ad hoc development methodology of never planning anything beyond a few user stories on a piece of card, verbally chewing the cud over the technicallities of a 3rd party integration ad nauseam without ever doing any real thinking or due dilligence and architecturally coupling all production code to the first test that comes into anyone's head for the past few months we reach the end of a release cycle and lo and behold the main externally visible feature that we have been developing is too slow to use, buggy, becoming labyrinthinly complex and completely inflexible. During this process "spikes" were done but never documented and not a single architectural design was ever produced (there was no FS, so what the hell eh, if you don't know what you are developing, how can you plan or research it?) - the project passed from pair to pair, each of whom only ever focused on a single user story at a time and well the result was inevitable. To resolve this I went off the radar, went (the dreaded) waterfall, planned, coded and basically didn't swap off the pair and tried as much as I could to work alone - focusing on solid architecture and specifications rather than unit tests which will come later once everything is pinned down. The code is now much better and is actually totally usable, flexible and fast. Certain people seem to have really resented me doing this and have gone out of their way to sabotage my efforts (possibly unconsciously) because it goes against the holy process of agile. So how do you, as a developer, explain to the team that it is not "un-agile" to plan their work, and how do you fit planning into the agile process? (I'm not talking about the IPM; I'm talking about sitting down with a problem and sketching out an end-to-end design that says how a problem should be solved in sufficient detail that anyone who works on the problem knows what architecture and patterns they should be using and where the new code should integrate into existing code)
