• Best method to organize/manage dependencies in the VCS within a large solution

  - by SnOrfus

  A simple scenario: 2 projects are in version control The application The test(s) A significant number of checkins are made to the application daily. CI builds and runs all of the automation nightly. In order to write and/or run tests you need to have built the application (to reference/load instrumented assemblies). Now, consider the application to be massive, such that building it is prohibitive in time (an entire day to compile). The obvious side effect here, is that once you've performed a build locally, it is immediately inconsistent with latest. For instance: If I were to sync with latest, and open up one of the test projects, it would not locally build until I built the application. This is the same when syncing to another branch/build/tag. So, in order to even start working, I need to wait a day to build the application locally, so that the assemblies could be loaded - and then those assemblies wouldn't be latest. How do you organize the repository or (ideally) your development environment such that you can continually develop tests against whatever the current build is, or a given specific build, while minimizing building the application as much as possible?

• Configuration Manager Setting Causing Error PRJ0019

  - by Jeff Paterno

  Recently I ran into an issue with a project failing to build on an automated build server using CruiseControl. When I looked into the build log I saw that the Post-Build project was failing with the error message: "error PRJ0019: A tool returned an error code from "Performing Post-Build Event..." This was most frustrating especially since the solution was building without issue on my local development environment. The Post-Build project was a C++ project that basically called several batch files to unregister/register assemblies, copy resources and supporting files, and place other dependencies in the GAC. I decided to run each of the batch files manually to see if that would provide more information as to why this project was failing. This lead me to determine that the batch file that was placing assemblies in the GAC was the culprit and that it was failing to find a particular assembly. The missing assembly was the output of another project. The project that was not producing the expected output was another C++ project that called a batch file. This batch process was actually embedding resource files into an assembly and then copying the assembly to the expected location. The real confusion started when I looked back into my Subversion log and noted that nothing had changed in this project in more than 2 months! It was almost as if the project had stopped building altogether. But what would cause that?! The Configuration Manager, obviously! Checking the solution's Configuration Manager settings, I found that the project that was not producing any output was in fact not selected to be part of the build process when the "Any CPU" platform was selected. This was the problem! I had recently updated the CruiseControl configurations to force the solution to be built targeting the platform "Any CPU". As a result, the project that was at the root of the problem was not configured to be built and the post-build process was failing when it couldn't find what it needed.

• Sync Google Contacts with QuickBooks

  - by dataintegration

  The RSSBus ADO.NET Providers offer an easy way to integrate with different data sources. In this article, we include a fully functional application that can be used to synchronize contacts between Google and QuickBooks. Like our QuickBooks ADO.NET Provider, the included application supports both the desktop versions of QuickBooks and QuickBooks Online Edition. Getting the Contacts Step 1: Google accounts include a number of contacts. To obtain a list of a user's Google Contacts, issue a query to the Contacts table. For example: SELECT * FROM Contacts. Step 2: QuickBooks stores contact information in multiple tables. Depending on your use case, you may want to synchronize your Google Contacts with QuickBooks Customers, Employees, Vendors, or a combination of the three. To get data from a specific table, issue a SELECT query to that table. For example: SELECT * FROM Customers Step 3: Retrieving all results from QuickBooks may take some time, depending on the size of your company file. To narrow your results, you may want to use a filter by including a WHERE clause in your query. For example: SELECT * FROM Customers WHERE (Name LIKE '%James%') AND IncludeJobs = 'FALSE' Synchronizing the Contacts Synchronizing the contacts is a simple process. Once the contacts from Google and the customers from QuickBooks are available, they can be compared and synchronized based on user preference. The sample application does this based on user input, but it is easy to create one that does the synchronization automatically. The INSERT, UPDATE, and DELETE statements available in both data providers makes it easy to create, update, or delete contacts in either data source as needed. Pre-Built Demo Application The executable for the demo application can be downloaded here. Note that this demo is built using BETA builds of the ADO.NET Provider for Google V2 and ADO.NET Provider for QuickBooks V3, and will expire in 2013. Source Code You can download the full source of the demo application here. You will need the Google ADO.NET Data Provider V2 and the QuickBooks ADO.NET Data Provider V3, which can be obtained here.

• How should I architect my Model and Data Access layer objects in my website?

  - by Robin Winslow

  I've been tasked with designing Data layer for a website at work, and I am very interested in architecture of code for the best flexibility, maintainability and readability. I am generally acutely aware of the value in completely separating out my actual Models from the Data Access layer, so that the Models are completely naive when it comes to Data Access. And in this case it's particularly useful to do this as the Models may be built from the Database or may be built from a Soap web service. So it seems to me to make sense to have Factories in my data access layer which create Model objects. So here's what I have so far (in my made-up pseudocode): class DataAccess.ProductsFromXml extends DataAccess.ProductFactory {} class DataAccess.ProductsFromDatabase extends DataAccess.ProductFactory {} These then get used in the controller in a fashion similar to the following: var xmlProductCreator = DataAccess.ProductsFromXml(xmlDataProvider); var databaseProductCreator = DataAccess.ProductsFromXml(xmlDataProvider); // Returns array of Product model objects var XmlProducts = databaseProductCreator.Products(); // Returns array of Product model objects var DbProducts = xmlProductCreator.Products(); So my question is, is this a good structure for my Data Access layer? Is it a good idea to use a Factory for building my Model objects from the data? Do you think I've misunderstood something? And are there any general patterns I should read up on for how to write my data access objects to create my Model objects?

• Inheriting projects - General Rules? [closed]

  - by pspahn

  Possible Duplicate: When is a BIG Rewrite the answer? Software rewriting alternatives Are there any actual case studies on rewrites of software success/failure rates? When should you rewrite? We're not a software company. Is a complete re-write still a bad idea? Have you ever been involved in a BIG Rewrite? This is an area of discussion I have long been curious about, but overall, I generally lack the experience to give myself an answer that I would fully trust. We've all been there, a new client shows up with a half-complete project they are looking to finish and launch. For whatever reason, they fired their previous developer, and it's now up to you to save the day. I am just finishing up a code review for a new client, and in my estimation is would be better to scrap what the previous developers built since and start from scratch. There's a ton of reasons why I am leaning toward this way, but it still makes me nervous since the client isn't going to want to hear "those last guys built you a big turd, and I can either polish it, or throw it in the trash". What are your general rules for accepting these projects? How do you determine whether it will be better to start from scratch or continue with the existing code base? What other extra steps might you take to help control client expectations, since the previous developer may have inflated those expectations beyond a reasonable level? Any other general advice?

• CPU Wars Is a Trump-Style Card Game Driven by Chip Stats

  - by Jason Fitzpatrick

  If you’re looking for the geekiest card game around, you’d be hard pressed to beat CPU Wars–a top-trumps card game built around CPU specs. From the game’s designers: CPU Wars is a trump card game built by geeks for geeks. For Volume 1.0 we chose 30 CPUs that we believe had the greatest impact on the desktop history. The game is ideally played by 2 or 3 people. The deck is split between the players and then each player takes a turn and picks a category that they think has the best value. We have chosen the most important specs that could be numerically represented, such as maximum speed achieved and maximum number of transistors. It’s lots of fun, it has a bit of strategy and can be played during a break or over a coffee. If you’re interested, you can pick up a copy for £7.99 (roughly $12.50 USD).

• boot up fails. drops to initramfs prompt 12.04

  - by dpm

  I am running an HP pavilion dv6000 dual boot win7 and Ubuntu 12.04. (well, up until today). after a reboot, the boot process drops to the busy box shell and i end up at the prompt: BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) Ive been researching others who have had this same problem, but haven't been able to find any of those solutions to work for me. I tried the method described here: http://www.proposedsolution.com/solutions/ubuntu-booting-to-initramfs-prompt/ and after the final command mount -t ntfs-3g /dev/sda1 /root -o force it does nothing and gives me another (initramfs) prompt. I can boot to a live CD (USB) and get to a terminal, but it doesn't seem to do much good, as I can see the /dev/sda1 in the ls command, but it doesn't recognize it when I try to cd to it. My command line skills are very green, and am just starting to grasp them. One more question: using the command fdisk -l how can I tell which mount point (sda1/sda2) is my windows partition and which one is Ubuntu? Any help? I'm in a bit over my head right now...

• DIY Homemade Hybrid Rocket Engine [Video]

  - by Jason Fitzpatrick

  Remember the guy with the cool DIY astronaut ice cream build? He’s back with a mini hybrid rocket engine that runs off oxygen and acrylic. I built a small rocket engine for demonstration purposes. The engine is built from a 2″ diameter acrylic rod through which I drilled a 0.5″ hole. The oxygen at 80 psi or less is passed through the hole and then is forced through a convergent-divergent nozzle at the tail end. The nozzle’s throat is about 0.25″ and expands to 0.625″. I lit the engine by inserting a burning cotton swab (with wooden stick) while a small amount of oxygen was flowing. The acrylic catches fire very easily in a pure oxygen environment. The engine can be throttled and shut off completely, which is a major benefit to hybrid engine designs. Solid-fuel rockets cannot be throttled or shut off, which makes them difficult to control.

• Can not mount /dev/loop0 (/cdrom/casper/filesystem.squashfs)

  - by simpleton

  I downloaded 12.04.1 and md5 sum checked them and everything is good. Made a live usb and booted up... Just gets to where its about to start with the purple ubuntu loading screen then it goes back to text and gives this message: BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) mount: mounting /dev/loop0 on ///filesystem.squashfs failed: Input/output error Can not mount /dev/loop0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs This happens in the live option, or persistent even the file checking one doesn't work Also I've tried a few different F6 options to no avail. I used 'LiLi USB creator' and 'unetbootin' and also 'Universal USB Installer,' all with the same results. I've also tried using a VM and it showed the same. That is when I figured I had a corrupt .iso so I downloaded it again checked the MD5: e235b63c02644e219b7bf3668f479c9e. Only I'm having the same problem. I'm just about ready to give up on 12.04.1 and just go back to 10.04 utill the next LTS comes out. I've got a dell mini 10 btw. Thanks for your time.

• Workaround: build FBX in XNA raise OutOfMemoryException

  - by Vitus

  If you try to add large FBX 3D model to the XNA project, and build it, you can get an OutOfMemoryException build error like following: Error    1    Building content threw OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.    at System.Collections.Generic.List`1.set_Capacity(Int32 value)    at System.Collections.Generic.List`1.EnsureCapacity(Int32 min)    at System.Collections.Generic.List`1.InsertRange(Int32 index, IEnumerable`1 collection)    at Microsoft.Xna.Framework.Content.Pipeline.Graphics.VertexChannel`1.InsertRange(Int32 index, Int32 count)    at Microsoft.Xna.Framework.Content.Pipeline.Graphics.VertexContent.InsertRange(Int32 index, IEnumerable`1 positionIndexCollection)    at Microsoft.Xna.Framework.Content.Pipeline.Graphics.MeshBuilder.AddTriangleVertex(Int32 indexIntoVertexCollection)    at Microsoft.Xna.Framework.Content.Pipeline.MeshConverter.FillNodeWithInfoFromMesh(KFbxNode* fbxNode, String name, KFbxGeometryConverter* geometryConverter)    at Microsoft.Xna.Framework.Content.Pipeline.FbxImporter.ProcessInformationInNode(KFbxNode* fbxNode, String name, Boolean* partOfMainSkeleton, Boolean* warnIfBoneButNotChild)    at Microsoft.Xna.Framework.Content.Pipeline.FbxImporter.ProcessNode(ValueType parentAbsoluteTransform, NodeContent potentialParent, KFbxNode* fbxNode, Boolean partOfMainSkeleton, Boolean warnIfBoneButNotChild)    at Microsoft.Xna.Framework.Content.Pipeline.FbxImporter.ProcessNode(ValueType parentAbsoluteTransform, NodeContent potentialParent, KFbxNode* fbxNode, Boolean partOfMainSkeleton, Boolean warnIfBoneButNotChild)    at Microsoft.Xna.Framework.Content.Pipeline.FbxImporter.Import(String filename, ContentImporterContext context)    at Microsoft.Xna.Framework.Content.Pipeline.ContentImporter`1.Microsoft.Xna.Framework.Content.Pipeline.IContentImporter.Import(String filename, ContentImporterContext context)    //additional calls here …   My desktop PC have 8Gb RAM, and Visual Studio’s process devenv.exe use under 2Gb of it while build process (about 3.5-4Gb of RAM is always free). It’s obvious, that VS can’t address more than 2Gb of RAM, and when that limit is over, build process is fail. OS on my PC is Win x64,  so I “charge” devenv.exe by using editbin.exe utility – in the VS Command prompt I run following: editbin "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe" /LARGEADDRESSAWARE This command edits the image to indicate that the application can handle addresses larger than 2 gigabytes. After that FBX file successfully built! Of course, you must put proper path to devenv.exe, depend on your installation path. If you are on Win x86, you need to do additional action – more info here.   P.S.: although now you can build a bigger files, than usual, keep in mind, that XNA have some restrictions on vertex buffer size etc., depend on your current XNA project profile (Reach or HiDef). And if your model’s vertexbuffer size more than 64Mb (with Reach profile), that model can’t be built and raise an error.

• Node.JS testing with Jasmine, databases, and pre-existing code

  - by Jim Rubenstein

  I've recently built the start of a core system which is likely going turn into a monster product. I'm building the system with node.js, and decided after I got a small base built, that It'd be a great idea to start using some sort of automated test suite to test the application. I decided to use jasmine, as it seems pretty solid and has a lot of features for stubbing spying and mocking methods and classes. The application has a lot of external data stores and api access (kestrel, mysql, mongodb, facebook, and more). My issue is, I've got a good amount of code written that I want to start testing - as it represents the underpinnings of the application. What are the best practices for testing methods/classes that access external APIs that I may or may not have control over? As an example, I have a data structure that fetches a bunch of data from a MySQL database. I want to test the method that retrieves the data; and I'm not sure how to go about it. I could test the fetch method which is supposed to return an array of objects, but to isolate the method from the database, I need to define my own fixture data. So what I end up doing is stubbing the mysql execution, and returning a static dataset. So, I end up writing a function that returns the dataset that makes my test pass. That doesn't seem to actually test the code, other than verifying a method is being called. I know this is kind of abstract and vague, it seems that the idea of testing is very much abstract though, so hopefully someone has some experience and can guide me in the right direction. Any advice, or reading I can do is more than welcomed. Thanks in advance.

• Nexus 7 Possibly Bricked

  - by user214186

  I have a 1st gen Nexus 7 (32GB). I used the steps at https://wiki.ubuntu.com/Nexus7/Installation to successfully install Ubuntu 13.04 desktop onto the tablet. It was working fine and then I decided to upgrade to Ubuntu Touch. I booted the tablet into fast boot mode but the commands 'adb devices' and 'sudo fastboot devices' would not see the device. I am performing these steps from an Ubuntu 12.04 desktop PC. Prior to installing 13.04 the device was seen fine. I made the mistake of performing the 'Device factory reset' step from https://wiki.ubuntu.com/Touch/Install - Step 2. Now when I try to boot the device I get the following: mount: mounting /dev on /root/dev failed: no such file or directory mount: mounting /dev on /root/sys failed: no such file or directory mount: mounting /proc on /root/proc failed: no such file or directory Targe filesystem doesn't have requested /sbin/init. No init found. Try passing init= bootarg. BusyBox v1.20.2 (Ubuntu 1:1.20.0-0ubuntu1) built-in shell (ash) Enter help for a list of built-in commands. (initramfs) I have searched the web but every reference to this problem is from people who still have ADB access to the device so they can recover by flashing the tablet again. I can attach a keyboard to the USB port and access the BusyBox console but I don't know what steps to do to recover from my error. Any suggestions would be helpful. Thanks

• Which .NET REST approach/technology/tool should I use?

  - by SonOfPirate

  I am implementing a RESTful web service and several client applications that are mostly in Silverlight. I am finding a litany of options for developing both the server-side and client-side of the API but am not sure which is the best approach. I'm concerned about stability as well as a platform that will continue to exist a few months from now. We started using the REST Starter Kit with .NET 3.5 but moved to the new WCF Web API when updating to .NET 4.0. All of their documentation indicates that WCF Web API is the replacement for the RSK. However, Web API is only in Preview 4 and does not include support for Silverlight or Windows Phone 7 clients (yet). WCF Web API looks like a wrapper on top of the WCF WebHttp Services stuff provided in the System.ServiceModel.Web library which makes me think that maybe it would be simpler to just go with the built-in stuff but Web API does offer some nice features. I am specifically tied-up trying to determine the best course for the client-side. My main requirement is that I need to support deserializing into my client-side objects quickly and easily. The Web API offers a nice client library but doesn't have a Silverlight version. I'd like to use the latest approach and the toolset that is being actively developed and supported. Is the REST Starter Kit really obsolete? Has anyone had any success implementing the WCF Web API toolkit? Is there merit to using either of these over the built-in WCF WebHttp Services features found in System.ServiceModel.Web? Is there a single solution that works for any client (web, Silverlight, etc.)? What suggestions do you have?

• Is the output of Eclipse's incremental java compiler used in production? Or is it simply to support Eclipse's features?

  - by Doug T.

  I'm new to Java and Eclipse. One of my most recent discoveries was how Eclipse comes shipped with its own java compiler (ejc) for doing incremental builds. Eclipse seems to by default output incrementally built class files to the projRoot/bin folder. I've noticed too that many projects come with ant files to build the project that uses the java compiler built into the system for doing the production builds. Coming from a Windows/Visual Studio world where Visual Studio is invoking the compiler for both production and debugging, I'm used to the IDE having a more intimate relationship with the command-line compiler. I'm used to the project being the make file. So my mental model is a little off. Is whats produced by Eclipse ever used in production? Or is it typically only used to support Eclipse's features (ie its intellisense/incremental building/etc)? Is it typical that for the final "release" build of a project, that ant, maven, or another tool is used to do the full build from the command line? Mostly I'm looking for the general convention in the Eclipse/Java community. I realize that there may be some outliers out there who DO use ecj in production, but is this generally frowned upon? Or is this normal/accepted practice?

• Be There: Tinkerforge/NetBeans Platform Integration Course

  - by Geertjan

  Tinkerforge is an electronic construction kit. It exposes a number of API bindings, including, of course, Java. The nice thing also is that Tinkerforge products are open source, both on the hardware and software levels, so that you can take their bases as a starting point for your own modifications. "The TinkerForge system is a set of pre-built electronics boards that are built in such a way that you can stack the boards (known as bricks), attach accessories (known as bricklets), and have your prototype and and running quickly. Unlike systems, such as the Arduino or Launchpad, the TinkerForge has to be attached to a computer and the computer does all of the work. With an easy set of application programming interfaces (APIs) available in C/C++, C#, Java, PHP, and Ruby, the system is easy to interface and program over USB in a snap." (from this useful article) Henning Krüp, who has arranged several NetBeans Platform Certified Training Courses in the past, in the Nordhorn/Lingen area in Germany, had the inspired idea to focus the next course on integration with Tinkerforge. In other words, the whole course will be focused on creating a standalone Java desktop application that leverages the NetBeans Platform to interact with Tinkerforge! Interested in joining the course or setting up something similar yourself? The course organized by Henning will be held from 19 to 21 September, as explained here, together with contact details.  If you'd like to organize a similar course at a location of your choosing, leave a comment at the end of this blog entry and we'll set something up together!

• Javascript form validation - what's lacking?

  - by box9

  I've tried out two javascript form validation frameworks - jQuery validation, and jQuery Tools validator - and I've found both of them lacking. jQuery validation lacks the clear separation between the concepts of "validating" and "displaying validation errors", and is highly inflexible when it comes to displaying dynamic error messages. jQuery Tools on the other hand lacks decent remote validation support (to check if a username exists for example). Even though jQuery validation supports remote validation, the built-in method requires the server to respond in a particular format. In both cases, any sort of asynchronous validation is a pain, as is defining rules for dependencies between multiple inputs. I'm thinking of rolling my own framework to address these shortcomings, but first I want to ask... have others experienced similar annoyances with javascript validation? What did you end up doing? What are some common validation requirements you've had which really should be catered for? And are there other, much better frameworks out there which I've missed? I'm looking primarily at jQuery-based frameworks, though well-implemented frameworks built on other libraries can still provide some useful ideas.

• Starting to Program C++ and Java

  - by user0321

  So as the title states, I'm trying to start programming in C++ and Java. I took C++ and Java courses in high school and I'm trying to get back into it. Of course all I want to get working now is a simple "Hello World" program. Couple of things: I want to use an IDE. I've decided on Eclipse. I'm just confused about how I go about downloading/using it. For Java: I get stuck right on their download page. They show Eclipse Classic, Eclipse IDE for Java developers and Eclipse IDE for Java EE Developers. I only programmed in Notepad and compiled in command prompt. Question 1: Which version of Eclipse should I download? Question 2: Do I need to install the Java JDK or does it come built into Eclipse? For C++: I guess I download the separate Eclipse IDE for C/C++ developers? I'm not too sure. I remember using Microsoft Visual for C++. I remember it being weird though. Anyways Question 3: Which version of Eclipse should I download? Question 4: Does C++ have a Development Kit or does it come built into Eclipse?

• Were the first assemblers written in machine code?

  - by The111

  I am reading the book The Elements of Computing Systems: Building a Modern Computer from First Principles, which contains projects encompassing the build of a computer from boolean gates all the way to high level applications (in that order). The current project I'm working on is writing an assembler using a high level language of my choice, to translate from Hack assembly code to Hack machine code (Hack is the name of the hardware platform built in the previous chapters). Although the hardware has all been built in a simulator, I have tried to pretend that I am really constructing each level using only the tools available to me at that point in the real process. That said, it got me thinking. Using a high level language to write my assembler is certainly convenient, but for the very first assembler ever written (i.e. in history), wouldn't it need to be written in machine code, since that's all that existed at the time? And a correlated question... how about today? If a brand new CPU architecture comes out, with a brand new instruction set, and a brand new assembly syntax, how would the assembler be constructed? I'm assuming you could still use an existing high level language to generate binaries for the assembler program, since if you know the syntax of both the assembly and machine languages for your new platform, then the task of writing the assembler is really just a text analysis task and is not inherently related to that platform (i.e. needing to be written in that platform's machine language)... which is the very reason I am able to "cheat" while writing my Hack assembler in 2012, and use some preexisting high level language to help me out.

• SharePoint Unit Testing and Load Testing Finally?

  - by Kit Ong

  It has always been a real pain to incorporate extensive SharePoint Unit Testing and Load Testing in a project, could Visual Studio 2012 finally make this easier? It certaining looks like it, here's a brief overview on SharePoint support in Visual Studio 2012. Load testing – We now support load testing for SharePoint out of the box. This is more involved than you might imagine due to how dynamic SharePoint is. You can’t just record a script and play it back – it won’t work because SharePoint generates and expects dynamic data (like GUIDs). We’ve built the extensions to our load testing solution to parse the dynamic SharePoint data and include it appropriately in subsequent requests. So now you can record a script and play it back and we will dynamically adjust it to match what SharePoint expects.Unit testing – One of the big problems with unit testing SharePoint is that most code requires SharePoint to be running and trying to run tests against a live SharePoint instance is a pain. So we’ve built a SharePoint “emulator” using our new VS 2012 Fakes & Stubs capability. This will make unit testing of SharePoint components WAY easier.Read more in the link belowhttp://blogs.msdn.com/b/bharry/archive/2012/09/12/visual-studio-update-this-fall.aspx

• SOA Starting Point: Methods for Service Identification and Definition

  As more and more companies start to incorporate a Service Oriented Architectural design approach into their existing enterprise systems, it creates the need for a standardized integration technology. One common technology used by companies is an Enterprise Service Bus (ESB). An ESB, as defined by Progress Software, connects and mediates all communications and interactions between services. In essence an ESB is a form of middleware that allows services to communicate with one another regardless of framework, environment, or location. With the emergence of ESB, a new emphasis is now being placed on approaches that can be used to determine what Web services should be built. In addition, what order should these services be built? In May 2011, SOA Magazine published an article that identified 10 common methods for identifying and defining services. SOA’s Ten Common Methods for Service Identification and Definition: Business Process Decomposition Business Functions Business Entity Objects Ownership and Responsibility Goal-Driven Component-Based Existing Supply (Bottom-Up) Front-Office Application Usage Analysis Infrastructure Non-Functional Requirements  Each of these methods provides various pros and cons in regards to their use within the design process. I personally feel that during a design process, multiple methodologies should be used in order to accurately define a design for a system or enterprise system. Personally, I like to create a custom cocktail derived from combining these methodologies in order to ensure that my design fits with the project’s and business’s needs while still following development standards and guidelines. Of these ten methods, I am particularly fond of Business Process Decomposition, Business Functions, Goal-Driven, Component-Based, and routinely use them in my designs.  Works Cited Hubbers, J.-W., Ligthart, A., & Terlouw , L.

• Kids and programming: ScratchKara

  - by Mike Pagel

  Ever now and then I kept wondering how to share with my kids the excitement of creating something with your computer. Of course, today this is a bit more difficult, as they have seen 3D animation games and well-edited websites. I guess that's why they weren't all that hyped when I found my first computer model at our local recycling facilities (an 8-bit Laser VZ-200 with rubber keys). When I finally got it up and running with an old analog TV set they finally asked whether we could play soccer on it. Needless to say that my showing them how it remembers some BASIC commands and lists and executes them did not make any impression. So the question is for real: How do you get today's kids excited about programming? And just recently I looked again for environments that allow even young kids (mine are 7 and 9 years old now) to do something and have fun. Obviously any real, text-oriented programming language wouldn't work well. To cut it short: Something really nice was built by University of Oldenburg: ScratchKara. It is the perfect mixture of Kara, a simulation of a little ladybug and Scratch, an authoring environment from MIT. ScratchKara allows kids to initially simply explore how the bug moves and turns by pressing the action buttons, then move towards sequencing commands through drag & drop, and eventually end up building algorithms with procedures and functions. Even through it is built for kids and beginners, the environment comes with debugging and refactoring, which I found more than amazing. My kids love it and I have to admit I keep thinking about how to solve a bit more advanced problems with this language, which does not allow you to store any state information (other than your call stack). Yes, I am hooked, too... Once the language is understood you can then move to one of the original Kara versions, where you can define the bug's behavior through finite statemachines, Turing tables, Java and other textual languages. And from there, anything is possible.

• My laptop with Linux/ Ubuntu isn't working

  - by Andy Campos

  I have a dell laptop with ubuntu linux. A day I tried to start it up and a black screen just appeared that says: GNU GRUB version1.98+20100804-5ubuntu3 (and these clickable options:) -Ubuntu, with Linux 2.6.35-22-generic -Ubuntu, with Linux 2.6.35-22-generic (recovery mode) -Memory test (memtest86+) -Memory test (memtest86+, serial console 115200) When I click the first one, a bunch of text appears like: mount: mounting /dev/disk/by-uuid/8396a225... failed: invalid argument mount: mounting /dev on /root/dev failed: no such file or directory mount: mounting /sys on /root/sys failed: no such file or directory mount: mounting /proc on /root/proc failed: no such file or directory Target file system doesn't have requested /sbin/init No init found. Try passing init= bootarg Enter 'help' for a list of built-in commands BusyBox v1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash) (initramfs) When I enter 'help' a bunch more incomprehensible text appears. Whenever I press the enter key all that pops up is (intetramfs) If anyone can make rhyme or reason out of this please, please help me out so it can boot up normally and i can be set. If there's some kind of special code I have to type in or something I know nothing about computers.
