• Using VirtualBox to test drive Windows Blue

  - by Fat Bloke

  Oracle VM VirtualBox is great for trying out the latest and greatest technologies and platforms. So when Microsoft recently announced the Developer Preview for Windows Server 2012 R2 and Windows 8.1,  it was with eager anticipation that FatBloke ran to the TechNet Evaluation Center to download the isos. Once downloaded,  a new VM in VirtualBox Manager was created that used Windows 2012 (64-bit) OS type and all the defaults were selected. And on starting the VM, and pointing to the iso file to install from, the excitement rose as we saw a cool new splashscreen image: But suddenly our hopes are dashed.... It would seem that this platform requires an instruction (CMPXCHG16B) that VirtualBox doesn't offer "out-of-the-box".  Fear not, for the VirtualBox team knew that this day would finally arrive and have prepared an "in case of emergency" switch as follows: Power off the vm; At the command line type:  VBoxManage setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1 Start the VM and install Windows Server 2012 R2 This will be enabled by default in a future release, but geeks can't wait, hence this blog. Enjoy! -FB

• How to Install WebLogic 12c ZIP on Linux

  - by Bruno.Borges

  I knew that WebLogic had this small ZIP distribution, of only 184M, but what I didn't know was that it is so easy to install it on Linux machines, specially for development purposes, that I thought I had to blog about it. You may want to check this blog, where I found the missing part on this how to, but I'm blogging this again because I wanted to put it in a simpler way, straight to the point. And if you are looking for a how to for Mac, check Arun Gupta's post.  So, here's the step-by-step: 1 - Download the ZIP distribution (don't worry if your system is x86_64)Don't forget to accept the OTN Free Developer License Agreement! 2 - Choose where to install your WebLogic server and your domain, and set as your MW_HOME environment variableI will use /opt/middleware/weblogic for this how to export MW_HOME=/opt/middleware/weblogicMake sure this path exists in your system. 'mydomains' will be used to keep your WebLogic domain. mkdir -p $MW_HOME/mydomain 3 - If you don't have your JAVA_HOME environment variable still configured, do it. Point it to where your JDK is installed. export JAVA_HOME=/usr/lib/jvm/default-java 4 - Unzip the downloaded file into MW_HOME unzip wls1211_dev.zip -d $MW_HOME 5 - Go to that directory and run configure.sh cd $MW_HOME ./configure.sh 6 - Call the setEnvs.sh script . $MW_HOME/wlserver/server/bin/setWLSEnv.sh7 - Create your development domain. It will ask you for username and password. I like to use weblogic / welcome1cd $MW_HOME/mydomain $JAVA_HOME/bin/java $JAVA_OPTIONS -Xmx1024m \ -Dweblogic.management.allowPasswordEcho=true weblogic.Server8 - Start WebLogic and access its web console(sh startWebLogic.sh &); sleep 10; firefox http://localhost:7001/consoleUsually, it takes only 10 seconds to start a domain, and 5 more to deploy the Administration Console (on my laptop). :-)Enjoy!

• Developing my momentum on open source projects

  - by sashang

  Hi I've been struggling to develop momentum contributing to open source projects. I have in the past tried with gcc and contributed a fix to libstdc++ but it was a once off and even though I spent months in my spare time on the dev mailing list and reading through things I just never seemed to develop any momentum with the code. Eventually I unsubscribed and got my free time back and uncluttered my mailbox. Like a lot of people I have some little open source defunct projects lying around on the net, but they're not large and I'm the only contributor. At the moment I'm more interested in contributing to a large open source project and want to know how people got started because I find it difficult while working full time to develop any momentum with the code base. Other more regular contributors, who are on the project full-time, are able to make changes at will and as result enter that positive feedback cycle where they understand the code and also know where it's heading. It makes the barrier to entry higher for those that come along later. My questions are to people who actively contribute to large opensource projects, like the Linux kernel, or gcc or clang/llvm or anything else with say a developer head count of more than 10. How did you get started? Was there a large chunk of time in your life that you just could dedicate to working on the project? I know in Linus's case he had a chunk of time (6 months) to get it started. What barriers to entry did you encounter? Can you describe the initial stages of the time spent with the project, from when you had little understanding of the code to when you understood enough to commit regularly. Thanks

• is there a checklist that a small website should

  - by Mecon

  I am not a web developer - this would be my first foray. I can do HTML/CSS/Javascript, but never created a website for a company. If anybody is creating a site for small company (expecting some 10-15 static pages), what kinda things would it need to have? I am thinking of the following: Make the eventual owner buy in his/her name: Domain name, Web Hosting package and Email package. Q - DO Web Developers generally ask their clients to buy this stuff and then ask them to share their passwords? OR - Do Web Developers ship the source files to clients so that they can upload it? Create Cross Browser compatible HTML+CSS+javascript pages Add SEO stuff like Meta tags and xml file for crawler Buy professional images from stock website Q - IS there is a best-practice for this step? Add Copyright stuff. Q - ANY idea about how to do this? Add Faceboook widgets, so people can 'like' my website. Register website somewhere so that its searchable from multiple search-engine/yellopages. Q - DOES such a thing exist? Please check my checklist :) and let me know what you think could be missing? Thanks!

• Working with the ADF DVT Map Component

  - by Shay Shmeltzer

  The map component provided by the ADF Faces DVT set of components is one that we are always ending up using in key demos - simply because it is so nice looking, but also because it is quite simple to use. So in case you need to show some geographical data, or if you just want to impress your manager, here is a little video that shows you how to create two types of maps. The first one is a color themed map - where you show different states with different colors based on the value of some data point there. The other is a point theme - basically showing specific locations on the map. For both cases I'm using the Oracle provided mapviewer instance at http://elocation.oracle.com/mapviewer. You can find more information about using the map component in the Web User Interface Developer's Guide here and in the tag doc and components demo. For the first map the query I'm using (on the HR demo schema in the Oracle DB) is: SELECT     COUNT(EMPLOYEES.EMPLOYEE_ID) , Department_name , STATE_PROVINCE FROM     EMPLOYEES,     DEPARTMENTS,     LOCATIONS WHERE employees.department_id=departments.department_idand Departments.location_id=locations.location_idGROUP BY Department_name,    LOCATIONS.STATE_PROVINCE

• Ubuntu One - Files API - Cloud - More detailed info somehwere?

  - by Brian McCavour

  I am just starting on a mobile app for Ubuntu One, and I'm reviewing the info at https://one.ubuntu.com/developer/files/store_files/cloud I find the information a bit lacking though. It's a nice reference, but for someone not familiar with it, I had to goggle search to find out what a "volume" was exactly (its kind of obvious, but never hurts to know the specifics) There's also things like: GET /api/file_storage/v1/volumes Return a JSON list of Volume Representations, one for each volume. A volume is a synced folder, or the Ubuntu One folder, owned by the user. Note that all volume paths begin with ~.: ... but there's no such thing as a JSON "list". Does it mean array ? And other things... So I was wondering if here existed another page with more detailed information. Maybe some sample request / responses or something? I could just write a little proof of concept app to answer some of these questions... but I prefer not to unless I have to. Thanks

• How to keep the trunk stable when tests take a long time?

  - by Oak

  We have three sets of test suites: A "small" suite, taking only a couple of hours to run A "medium" suite that takes multiple hours, usually ran every night (nightly) A "large" suite that takes a week+ to run We also have a bunch of shorter test suites, but I'm not focusing on them here. The current methodology is to run the small suite before each commit to the trunk. Then, the medium suite runs every night, and if in the morning it turned out it failed, we try to isolate which of yesterday's commits was to blame, rollback that commit and retry the tests. A similar process, only at a weekly instead of nightly frequency, is done for the large suite. Unfortunately, the medium suite does fail pretty frequently. That means that the trunk is often unstable, which is extremely annoying when you want to make modifications and test them. It's annoying because when I check out from the trunk, I cannot know for certain it's stable, and if a test fails I cannot know for certain if it's my fault or not. My question is, is there some known methodology for handling these kinds of situations in a way which will leave the trunk always in top shape? e.g. "commit into a special precommit branch which will then periodically update the trunk every time the nightly passes". And does it matter if it's a centralized source control system like SVN or a distributed one like git? By the way I am a junior developer with a limited ability to change things, I'm just trying to understand if there's a way to handle this pain I am experiencing.

• Reformatting and version control

  - by l0b0

  Code formatting matters. Even indentation matters. And consistency is more important than minor improvements. But projects usually don't have a clear, complete, verifiable and enforced style guide from day 1, and major improvements may arrive any day. Maybe you find that SELECT id, name, address FROM persons JOIN addresses ON persons.id = addresses.person_id; could be better written as / is better written than SELECT persons.id, persons.name, addresses.address FROM persons JOIN addresses ON persons.id = addresses.person_id; while working on adding more columns to the query. Maybe this is the most complex of all four queries in your code, or a trivial query among thousands. No matter how difficult the transition, you decide it's worth it. But how do you track code changes across major formatting changes? You could just give up and say "this is the point where we start again", or you could reformat all queries in the entire repository history. If you're using a distributed version control system like Git you can revert to the first commit ever, and reformat your way from there to the current state. But it's a lot of work, and everyone else would have to pause work (or be prepared for the mother of all merges) while it's going on. Is there a better way to change history which gives the best of all results: Same style in all commits Minimal merge work ? To clarify, this is not about best practices when starting the project, but rather what should be done when a large refactoring has been deemed a Good Thing™ but you still want a traceable history? Never rewriting history is great if it's the only way to ensure that your versions always work the same, but what about the developer benefits of a clean rewrite? Especially if you have ways (tests, syntax definitions or an identical binary after compilation) to ensure that the rewritten version works exactly the same way as the original?

• Is Apple getting out of the general purpose development platform business?

  - by Charles E. Grant

  I've been doing general ANSI C/Console C++/Java/Web development on Mac hardware for about ten years. I make no claims of objective superiority over other platforms, it just satisfies my personal tastes. With the success of the iPhone and the related App store there was some speculation that Apple would get out of the general purpose computer market, and become a closed software ecosystem, focusing on consumer appliances. I pooh-poohed the speculation at the time, but this week Apple announced that a) they were opening an App store for the Mac, b) Java applications would not be eligible for the App store, c) the Apple JVM was being deprecated and might not be available for future releases of OS X. I'm not a Java developer per se, but I work in a research lab that occasionally writes Java applications, and also depends on tools written Java. This has the potential to be a huge pain in the butt for us. As of now, there is no other JVM for OS X that we can point our end users to. Soy Latte and OpenJDK might be appropriate for developers, but the complexity of the installation makes them inappropriate for end users. Eventually I expect Oracle/SUN will produce a replacement JVM for OS X. More worrisome to me is that Apple used to specifically advertise that it was an excellent platform for scientific development, because they supported all major language platforms. Is the deprecation of their JVM a sign that this market no longer interests them?

• What is a 'good number' of exceptions to implement for my library?

  - by Fuzz

  I've always wondered how many different exception classes I should implement and throw for various pieces of my software. My particular development is usually C++/C#/Java related, but I believe this is a question for all languages. I want to understand what is a good number of different exceptions to throw, and what the developer community expect of a good library. The trade-offs I see include: More exception classes can allow very fine grain levels of error handling for API users (prone to user configuration or data errors, or files not being found) More exception classes allows error specific information to be embedded in the exception, rather than just a string message or error code More exception classes can mean more code maintenance More exception classes can mean the API is less approachable to users The scenarios I wish to understand exception usage in include: During 'configuration' stage, which might include loading files or setting parameters During an 'operation' type phase where the library might be running tasks and doing some work, perhaps in another thread Other patterns of error reporting without using exceptions, or less exceptions (as a comparison) might include: Less exceptions, but embedding an error code that can be used as a lookup Returning error codes and flags directly from functions (sometimes not possible from threads) Implemented an event or callback system upon error (avoids stack unwinding) As developers, what do you prefer to see? If there are MANY exceptions, do you bother error handling them separately anyway? Do you have a preference for error handling types depending on the stage of operation?

• Best way: restructure an existing Team Foundation Server (TFS) solution

  - by dhh

  In my department we are developing several smaller AddOns for some unified communication server. For versioning and distributed development we use a Team Foundation Server 2012. But: there is only one large TFS solution for all of our applications and libraries: Main Solution Applications App 1 App 2 App 3 Externals Libraries Lib 1 Lib 2 Tools The "Application" path contains all main applications. Those are not depending on each other, but they depend on the Libraries and Externals projects. The "Externals" path contains some external DLLs referenced in our Applications and Libraries. The Libraries path contains commonly used libs (UI templates, Helper classes, etc.). They do not depend on each other and they are referenced in the Libraries and the Tools projects. The Tools path contains some helper programs like setup helpers, update web services, etc. Now, there's some major points why I'd like to change this structure: We can't use server builds. It's uncomfortable to manage TFS scrum management with sprints, impediments, etc. with a solution structure like that. Every developer always has access to all projects in the solution. A complete build lasts too long if one accidentally hits [F6] in Visual Studio... What would you change in this solution? How would you break those projects into smaller Solutions, how should those solutions be structured. My first approach would be, to create one TFS project for each Application, Library and Tool. But how can I ensure that e.g. App 2 always contains the newest version of Lib 1? Do I have to monitor changes on Lib 1 and update App 2 manually as soon as the Lib changes? Or can I somehow force Visual Studio to always use the newest version of an external project somehow?

• Should I listen to my employer and use CASE tools?

  - by omsharp

  My employer (Not a Developer) thinks that CASE tools will help us improve our development process and documentation. I am not sure about that, we are a small team of 5 developers building mobile banking solutions for local clients. I think CASE tools will be a waste of time and money as they need to be purchased and we will need some time before we get used to them and be efficient working with them for modeling and stuff. Code generation is another issue, I really think that the CASE generated code won't be as good as code written by good developers. I think that if we stick with agile princeliness, design patterns, use TDD, and keep our code clean. we should be good. And as far as Analysis and Design, I think simple UML diagrams on whiteboard should do the trick. Documentation is good and important, but should be made as little as possible and we should not focus on Docs and forget the code. This is what i think. Am I correct? or should I listen to my employer and start researching for an appropriate CASE Tool?

• JDeveloper News &ndash; Did You Know

  - by shay.shmeltzer

  There have been a few issues lately with access to blogs.oracle.com to write new messages – and as a result I’m a little behind on reporting the latest and greatest in JDeveloper. (I’m also unable to approve comments :-( ) But just in case you missed it here are a few note worthy things you should know: ADF Mobile Client went production – this is a solution that let you use ADF to develop on-device applications for mobile devices. You develop once and run on various devices (right now Blackberry and Windows Mobile with other platforms coming soon). For more information check out the ADF Mobile page on OTN. ADF Developer Certification goes production – you can now take the official test and get an official certification that you can include in your resume.Should be a must for any consultant looking to get ADF related gigs. Learn more about the ADF Certification Exam. ADF Vision Stencils Released – If you are looking for a quick way to draw prototypes of ADF screens you probably can’t get any faster and more accurate results than this. This is a set of Vision components that you can drag over and design a page visually. You can also set properties for components and do other advance things. You do need a license for Visio to use this, but the ADF stencils are free. We’ve been using these internally at Oracle for some time now and we thought the ADF community would enjoy these too. Download the ADF Visio Stencils here (and watch a youtube demo of how they work).

• Is it worth moving from Microsoft tech to Linux, NodeJS & other open source frameworks to save money for a start-up?

  - by dormisher

  I am currently getting involved in a startup, I am the only developer involved at the moment, and the other guys are leaving all the tech decisions up to me at the moment. For my day job I work at a software house that uses Microsoft tech on a day to day basis, we utilise .NET, SqlServer, Windows Server etc. However, I realise that as a startup we need to keep costs down, and after having a brief look at the cost of hosting for Windows I was shocked to see some of the prices for a dedicated server. The cheapest I found was £100 a month. Also if the business needs to scale in the future and we end up needing multiple servers, we could end up shelling out £10's of £000's a year in SQL Server / Windows Server licenses etc. I then had a quick look at the price of Linux hosting for a dedicated server and saw the price was waaaaaay lower than windows hosting. One place was offering a machine with 2 cores for less than £20 a month. This got me thinking maybe the way to go is open source on Linux. As I write a lot of Javascript at work (I'm working on a single page backbone app at the moment), I thought maybe NodeJS and a web framework like Express would be cool to use. I then thought that instead of using SQL why not use an open source NoSQL database like MongoDB, which has great support on NodeJS? My only concern is that some of the work the application is going to do is going to be dynamically building images and various other image related stuff, i.e. stuff that is quite CPU heavy - so I'm thinking of maybe writing anything CPU heavy in C++ and consuming it as a module in Node. That's the background - but basically is Linux a good match for: Hosting a NodeJS/Express site? Compiling C++ node modules? Using a NoSQL DB like MongoDB? And is it a good idea to move to these unfamiliar technologies to save money?

  - by Tim Murphy

  Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/06/27/build-2013-sessionndashalive-with-activity.aspx Live tiles are what really add a ton of value to both Windows 8 and Windows Phone.  As a developer it is important that you leverage this capability in order to make your apps more informative and give your users a reason to keep opening the app to find out details hinted at by tile updates. In this session Kraig Brockschmidt cover a wide array of dos and don’ts for implementing live tiles.  I was actually worried whether I would get much out of this session when Kraig started it off with the fact that his background is in HTML5 based apps which I have little interest in, but the subject almost didn’t come up during his talk.  It focused on things like making sure you have all the right size graphics and implementing all of the tile event handlers.  The session went on to discuss the message format for push notification and implementing lock screen notification and badges. As with the other day 1 sessions it was like drinking from a fire hose, but it was good stuff.  Check it out when they post it on Channel 9. del.icio.us Tags: BUILD 2013,Live Tiles,Windows 8.1

• Necessary Infrastructure for large project with many components communicating through IPCs

  - by jluzwick

  I have a fairly in depth question which probably doesn't have an exact answer. As a software engineer, I am usually tasked with working on a program or project with minimal understanding of how other components or programs in the project interact with each other. When one program fails in a sea of multiple components and processes, what infrastructure elements are necessary to ensure that the problem can be accurately tracked to the violating application? More specifically, what infrastructure elements should be necessary for this large project and which are optional but very helpful. One such example I can think of is some form of a common logging infrastructure that allows for a developer or tester to easily browse through a log that contains numerous components for messages that might allude to the culprit program along with a "trail" of what happened before the issue occurred. I'm thinking of something similar to Androids alogcat tool. These necessary infrastructure elements should be language-agnostic. While these elements should be understood by all engineers on the team in question, which elements should be understood at great detail by the technical system engineers and what should the individual software engineers be responsible for adding to their tools to allow for such infrastructures to take hold? Please feel free to ask for clarification if something does not make sense as I understand this question is very broad and needs some refinement. I will refine as necessary from the answers and comments I receive. Thanks for any help!

• CSOM (Client Side Object Model) - What's new with SharePoint 2013

  - by KunaalKapoor

  SharePoint CSOMThe Client-Side Object Model or CSOM came out with SharePoint 2010. CSOM is accessible through client.svc but all client.svc calls must go through supported WFC entry points (supported entry points are .NET, Silverlight and JavaScript). So a developer would need to use client side proxy objects exposed by either a .NET assembly or a JavaScript library. Changes with SharePoint 2013REST Capabilities - Direct access to client.svcNew APIs - App ModelREST CapabilitiesOne of the most important changes to the CSOM with SharePoint 2013 is that the web service entry point of client.svc has been extended to allow direct access  via REST-Based web service calls. This is a really critical change since its going to make the SharePoint platform accessible to any other platform, opening the horizons of integration and collaboration with other REST based platforms and devices. OData (a really popular standard data access API for HTTP-based clients) is supported similar to 2010 but will be a more important aspect of SharePoint 2013 development.New API'sCSOM for SharePoint 2013 has been buffed up with several new APIs for not only SharePoint server functionality but also an API for Windows Phone applications. For a SharePoint 2010 farm most of the new APIs mentioned below are available only via server side APIs:SearchTaxonomyPublishingWorkflowUser ProfilesE-DiscoveryAnalyticsBusiness DataIRMFeedsSharePoint 2013 remote APIs being accessible through both CSOM and REST is very important to the new app model where developers can no longer run code in a SharePoint environment nor can they access the server-side APIs. So CSOM plays the savior here.Also, you can now substitute the alias '_api' in order to reference '_vti_bin/client.svc'.

• How far should one take e-mail address validation?

  - by Mike Tomasello

  I'm wondering how far people should take the validation of e-mail address. My field is primarily web-development, but this applies anywhere. I've seen a few approaches: simply checking if there is an "@" present, which is dead simply but of course not that reliable. a more complex regex test for standard e-mail formats a full regex against RFC 2822 - the problem with this is that often an e-mail address might be valid but it is probably not what the user meant DNS validation SMTP validation As many people might know (but many don't), e-mail addresses can have a lot of strange variation that most people don't usually consider (see RFC 2822 3.4.1), but you have to think about the goals of your validation: are you simply trying to ensure that an e-mail address can be sent to an address, or that it is what the user probably meant to put in (which is unlikely in a lot of the more obscure cases of otherwise 'valid' addresses). An option I've considered is simply giving a warning with a more esoteric address but still allowing the request to go through, but this does add more complexity to a form and most users are likely to be confused. While DNS validation / SMTP validation seem like no-brainers, I foresee problems where the DNS server/SMTP server is temporarily down and a user is unable to register somewhere, or the user's SMTP server doesn't support the required features. How might some experienced developers out here handle this? Are there any other approaches than the ones I've listed? Edit: I completely forgot the most obvious of all, sending a confirmation e-mail! Thanks to answerers for pointing that one out. Yes, this one is pretty foolproof, but it does require extra hassle on the part of everyone involved. The user has to fetch some e-mail, and the developer needs to remember user data before they're even confirmed as valid.

• During interviews, how do I gauge a company's respect for my position?

  - by Bluu

  I'm a web developer who previously joined a software company not knowing their value and respect went to big data analysis, not their website. Sure, they needed a public-facing website, but I eventually found that the most exciting, valued projects there went to data teams. Realizing this, members of the web team were picked off and switched teams, making it hard for those left behind to keep up the work load, and making us look bad. At times it seemed the company culture sneered at us, wondering, "What does that team even do here?" A friend of mine had the opposite problem at another software company. All he wanted to do was crunch big numbers. However he complained that the rest of the company wouldn't shut up about developing the usability of their website. Meanwhile his analytics team languished. I've also heard of salespeople getting love at a company, while engineering as a whole is undervalued, or vice versa. As for my story, if I could have known the company was like that, I might have avoided the job in the first place. So, before I join a new company, how do I gauge its actual respect for my programming role? For its other roles? I want to avoid companies that aren't serious about my particular focus in programming, or, perhaps bigger picture, companies that don't value everybody who works there. (Note I think gauging the company's attitude toward the basic needs of its programmers is covered by these related questions.)

• Using template questions in a technical interview

  - by Desolate Planet

  I've recently been in an argument with a colleague about technical questions in interviews. As a graduate, I went round lots of companies and noticed they used the same questions. An example is "Can you write a function that determines if a number is prime or not?", 4 years later, I find that particular question is quite common even for a junior developer. I might not be looking at this the correct way, but shouldn't software houses be intelligent enough to think up their own interview questions? I've been to about 16 interviews as a graduate and the same questions came up in about 75% of them. This leads me to believe that many companies are lazy and simply Google: 'Template questions for interviewing software developers' and I look down on that. Question: Is it better to use a set of questions off some template or should software houses strive to be more original and come up with their own interview material? From my point of view, if I failed an interview and went off and looked for good answers to the questions I messed up on, I could fly through the next interview if the questions are the same.

• Should I be learning Linq, Direct SQL Commands (in .net), EF or other?

  - by Wil

  Basically, I have a very good knowledge of plain old SQL coming from Classic ASP programming. Over the past couple of months, I have been learning C# and today was my first full day at MVC 3 (Razor) which I am loving! I need to get back in to Databases and I know that writing SqlCommand everywhere is obviously outdated (although it is nice I can still do it!). I used to go to a great usergroup as an IT Pro and the developer stuff went completely over my head, however I do remember a few things which kept coming up such as LINQ... However, that was some time ago and now the same people on Twitter are saying how out dated it is. I have tried to do research on both and I am clueless as to what direction I should go in, or when to use one over another (if learning both is a good thing). I am more so confused as I thought EF was a part of the .Net Framework, however, reading through the quick start guide, I had to download a component using Nuget. ... Basically I am out of my depth here and just need some honest advice of where to go!

• Good practices when optimizing HTML5/Javascript Game Developement [closed]

  - by hustlerinc

  I'm just starting out as a game developer and have created a few crappy but playable clones of classic games like pong, and bomberman. Being self taught (bless the internet) I do this by just stuffing in code to make the games work. Now I feel the time has come to create something complete, for this I need to know how a game is structured. I've searched on the web but there isn't that much to be found. The only "high-level" language I know is javascript so reading a tutorial or article based on C++ doesn't help me that much. I'm looking for good resource's pedagogically covering the theory and possibly examples (in Javascript or pseudo code that is understandable for a beginner) of how the game pieces fit together. From the start screen to asset loading and running the game loop. I'm not looking for anything complicated like reading through a 4000 line source code. All I want to learn is where, how and when the main parts of every game should be called. If you know any good resources to share, or maybe even have an answer for me I would deeply appreciate it.

• Are there any good examples of open source C# projects with a large number of refactorings?

  - by Arjen Kruithof

  I'm doing research into software evolution and C#/.NET, specifically on identifying refactorings from changesets, so I'm looking for a suitable (XP-like) project that may serve as a test subject for extracting refactorings from version control history. Which open source C# projects have undergone large (number of) refactorings? Criteria A suitable project has its change history publicly available, has compilable code at most commits and at least several refactorings applied in the past. It does not have to be well-known, and the code quality or number of bugs is irrelevant. Preferably the code is in a Git or SVN repository. The result of this research will be a tool that automatically creates informative, concise comments for a changeset. This should improve on the common development practice of just not leaving any comments at all. EDIT: As Peter argues, ideally all commit comments would be teleological (goal-oriented). Practically, if a comment is made at all it is often descriptive, merely a summary of the changes. Sadly we're a long way from automatically inferring developer intentions!
