• Getting overwhelmed after starting a new project

  - by Kian Mayne

  I started a project (a Windows based timetable program that helps you stay organised with your subjects and assignments). The problem is that I'm not sure how I should manage this project and what order to build things. I.e. Should I build all the different interface elements then write the code or should I make an interface, code it, make another interface then code that? So my question is; how do I split up this longish project into small, ordered pieces to complete; and how should I order this?

• What is wrong with my Dot Product? [Javascript]

  - by Clay Ellis Murray

  I am trying to make a pong game but I wanted to use dot products to do the collisions with the paddles, however whenever I make a dot product objects it never changes much from .9 this is my code to make vectors vector = { make:function(object){ return [object.x + object.width/2,object.y + object.height/2] }, normalize:function(v){ var length = Math.sqrt(v[0] * v[0] + v[1] * v[1]) v[0] = v[0]/length v[1] = v[1]/length return v }, dot:function(v1,v2){ return v1[0] * v2[0] + v1[1] * v2[1] } } and this is where I am calculating the dot in my code vector1 = vector.normalize(vector.make(ball)) vector2 = vector.normalize(vector.make(object)) dot = vector.dot(vector1,vector2) Here is a JsFiddle of my code currently the paddles don't move. Any help would be greatly appreciated

• Recaptcha php problem [closed]

  - by Sam Gabriel

  Hey guys, I'm using recaptcha and I've got a problem, when a user clicks the signup button it redirects him to the sign up verification page, and here is the code, found on the very top of the web code, that checks the recaptcha entered data. <?php require_once('recaptchalib.php'); $privatekey = "***"; $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); if (!$resp->is_valid) { header('location: signup.php'); } ?> But it seems whatever I type in in the recaptcha box, be it right or wrong, I get redirected to the signup.php page. Here is the recaptcha code in the signup.php page: <?php ini_set('display_errors', 'On'); error_reporting(E_ALL | E_STRICT); require_once('recaptchalib.php'); $publickey = "***"; echo recaptcha_get_html($publickey); ?>

• Homemaking a 2d soft body physics engine

  - by Griffin

  hey so I've decided to Code my own 2D soft-body physics engine in C++ since apparently none exist and I'm starting only with a general idea/understanding on how physics work and could be simulated: by giving points and connections between points properties such as elasticity, density, mass, shape retention, friction, stickiness, etc. What I want is a starting point: resources and helpful examples/sites that could give me the specifics needed to actually make this such as equations and required physics knowledge. It would be great if anyone out there also would give me their attempts or ideas. finally I was wondering if it was possible to... use the source code of an existing 3D engine such as Bullet and transform it to be 2D based? use the source code of a 2D Rigid body physics engine such as box2d as a starting point?

• Should the Joel Test be essential for every software company? [closed]

  - by Mahbubur R Aaman

  Joel Test has 12 steps for better code. They are: Do you use source control? Can you make a build in one step? Do you make daily builds? Do you have a bug database? Do you fix bugs before writing new code? Do you have an up-to-date schedule? Do you have a spec? Do programmers have quiet working conditions? Do you use the best tools money can buy? Do you have testers? Do new candidates write code during their interview? Do you do hallway usability testing? Should these steps mandatory for every software companies? While recruiting programmers, then programmers should ask the company, as they follow joel steps?

• Forking a dual licensed app: How to license on my end?

  - by TheLQ

  I forked a project that was dual licensed under the GPL and a commercial license. Since my code was open source and the GPL being what it is, I started by releasing my app under the GPL. But now I'm thinking about dual licensing the project and can't figure out what to do. Since I have copyright on a majority of the code (most of the code was either rewritten or new), can I just pick a commercial license or do I have to buy the upstream commercial license since I'm technically a "derivative" of the project?

• How to learn to draw UML sequence diagrams

  - by PeterT

  How can I learn to draw UML sequence diagrams. Even though I don't use UML much I find that type of diagrams to be quite expressive and want to learn how to draw them. I don't plan to use them to visualise a large chunks of code, hence I would like to avoid using tools, and learn how to draw them with just pen and paper. Muscle memory is good. I guess I would need to learn some basics of notation first, and then just practice it like in "take the piece of code, draw a seq. diagram visualising the code, then generate the diagram using some tool/website, then compare what I'd drawn to what the tool result. Find the differences, correct them, repeat.". Where do I start? Can you recommend a book or a web site or something else?

• When should I make the first commit to source control?

  - by Kendall Frey

  I'm never sure when a project is far enough along to first commit to source control. I tend to put off committing until the project is 'framework-complete' and primarily commit features from then on. (I haven't done any personal projects large enough to have a core framework too big for this.) I have a feeling this isn't best practice, though I'm not sure what all could go wrong. Let's say, for example, I have a project which consists of a single code file. It will take about 10 lines of boilerplate code, and 100 lines to get the project working with extremely basic functionality (1 or 2 features). Should I first check in: The empty file? The boilerplate code? The first features? At some other point? Also, what are the reasons to check in at a specific point?

• Must-do activities for a team leader, and time managing them

  - by MeLight

  This is a two part question Part one: I'm leading a small team of developers of mixed skills (juniors and seniors). I'm sometimes feeling that I focus too much on my own code, instead of seeing the big the picture, and managing the team. What would you say the most crucial non-coding activities for a team leader, related to his team members? Part two:Given that I know what other (non-coding stuff) I should be doing, what is a good time division between my own code writing and managing the other team members (code reviews, whiteboarding, meetings etc).

• Any good, easy to learn from books or tutorials for learning assembly? [on hold]

  - by pythonian29033

  I've been a developer since 2009 and I've learnt a lot of languages since, but I've always wanted to understand and be able to code in the lowest level language so I can directly (or at least very close to directly) speak to machines through my code. There was a point in time when someone showed me how to do an if statement in assembly, but out of all the books that I got, I could never really understand where/how to start learning to code in assembler. any help please? I'm obsessed with learning this! PS: if you have any software suggestions, I use ubuntu and am looking to convert to backtrack soon, so it would be preferred if you could give me something that'll be easily installed on debian linux, otherwise don't sweat it, give me the name of the windows software and I'll find an equivalent myself

• What happened to HTML table tags?

  - by John

  I started to code HTML in 1998, and in that time I was used to code a lot table tags, playing with tr and td, I learned many things analysing the source code of many portals on the internet with notepad and Microsoft FrontPage, the latter, aw, how many tables overlapping others, it was fun, I loved that time. However, I abandoned web programming for almost seven years and this year I decided to see what's the web programming today likes. Completely different, there are not table tags anymore, it's full of div and span tags. Why happened ? What are these new tags and why nobody codes in table tags anymore ?

• Goto for the Java Programming Language

  - by darcy

  Work on JDK 8 is well-underway, but we thought this late-breaking JEP for another language change for the platform couldn't wait another day before being published. Title: Goto for the Java Programming Language Author: Joseph D. Darcy Organization: Oracle. Created: 2012/04/01 Type: Feature State: Funded Exposure: Open Component: core/lang Scope: SE JSR: 901 MR Discussion: compiler dash dev at openjdk dot java dot net Start: 2012/Q2 Effort: XS Duration: S Template: 1.0 Reviewed-by: Duke Endorsed-by: Edsger Dijkstra Funded-by: Blue Sun Corporation Summary Provide the benefits of the time-testing goto control structure to Java programs. The Java language has a history of adding new control structures over time, the assert statement in 1.4, the enhanced for-loop in 1.5,and try-with-resources in 7. Having support for goto is long-overdue and simple to implement since the JVM already has goto instructions. Success Metrics The goto statement will allow inefficient and verbose recursive algorithms and explicit loops to be replaced with more compact code. The effort will be a success if at least twenty five percent of the JDK's explicit loops are replaced with goto's. Coordination with IDE vendors is expected to help facilitate this goal. Motivation The goto construct offers numerous benefits to the Java platform, from increased expressiveness, to more compact code, to providing new programming paradigms to appeal to a broader demographic. In JDK 8, there is a renewed focus on using the Java platform on embedded devices with more modest resources than desktop or server environments. In such contexts, static and dynamic memory footprint is a concern. One significant component of footprint is the code attribute of class files and certain classes of important algorithms can be expressed more compactly using goto than using other constructs, saving footprint. For example, to implement state machines recursively, some parties have asked for the JVM to support tail calls, that is, to perform a complex transformation with security implications to turn a method call into a goto. Such complicated machinery should not be assumed for an embedded context. A better solution is just to expose to the programmer the desired functionality, goto. The web has familiarized users with a model of traversing links among different HTML pages in a free-form fashion with some state being maintained on the side, such as login credentials, to effect behavior. This is exactly the programming model of goto and code. While in the past this has been derided as leading to "spaghetti code," spaghetti is a tasty and nutritious meal for programmers, unlike quiche. The invokedynamic instruction added by JSR 292 exposes the JVM's linkage operation to programmers. This is a low-level operation that can be leveraged by sophisticated programmers. Likewise, goto is a also a low-level operation that should not be hidden from programmers who can use more efficient idioms. Some may object that goto was consciously excluded from the original design of Java as one of the removed feature from C and C++. However, the designers of the Java programming languages have revisited these removals before. The enum construct was also left out only to be added in JDK 5 and multiple inheritance was left out, only to be added back by the virtual extension method methods of Project Lambda. As a living language, the needs of the growing Java community today should be used to judge what features are needed in the platform tomorrow; the language should not be forever bound by the decisions of the past. Description From its initial version, the JVM has had two instructions for unconditional transfer of control within a method, goto (0xa7) and goto_w (0xc8). The goto_w instruction is used for larger jumps. All versions of the Java language have supported labeled statements; however, only the break and continue statements were able to specify a particular label as a target with the onerous restriction that the label must be lexically enclosing. The grammar addition for the goto statement is: GotoStatement: goto Identifier ; The new goto statement similar to break except that the target label can be anywhere inside the method and the identifier is mandatory. The compiler simply translates the goto statement into one of the JVM goto instructions targeting the right offset in the method. Therefore, adding the goto statement to the platform is only a small effort since existing compiler and JVM functionality is reused. Other language changes to support goto include obvious updates to definite assignment analysis, reachability analysis, and exception analysis. Possible future extensions include a computed goto as found in gcc, which would replace the identifier in the goto statement with an expression having the type of a label. Testing Since goto will be implemented using largely existing facilities, only light levels of testing are needed. Impact Compatibility: Since goto is already a keyword, there are no source compatibility implications. Performance/scalability: Performance will improve with more compact code. JVMs already need to handle irreducible flow graphs since goto is a VM instruction.

• Guidance: How to layout you files for an Ideal Solution

  - by Martin Hinshelwood

  Creating a solution and having it maintainable over time is an art and not a science. I like being pedantic and having a place for everything, no matter how small. For setting up the Areas to run Multiple projects under one solution see my post on  When should I use Areas in TFS instead of Team Projects and for an explanation of branching see Guidance: A Branching strategy for Scrum Teams. Update 17th May 2010 – We are currently trialling running a single Sprint branch to improve our history. Whenever I setup a new Team Project I implement the basic version control structure. I put “readme.txt” files in the folder structure explaining the different levels, and a solution file called “[Client].[Product].sln” located at “$/[Client]/[Product]/DEV/Main” within version control. Developers should add any projects you need to create to that solution in the format “[Client].[Product].[ProductArea].[Assembly]” and they will automatically be picked up and built automatically when you setup Automated Builds using Team Foundation Build. All test projects need to be done using MSTest to get proper IDE and Team Foundation Build integration out-of-the-box and be named for the assembly that it is testing with a naming convention of “[Client].[Product].[ProductArea].[Assembly].Tests” Here is a description of the folder layout; this content should be replicated in readme files under version control in the relevant locations so that even developers new to the project can see how to do it. Figure: The Team Project level - at this level there should be a folder for each the products that you are building if you are using Areas correctly in TFS 2010. You should try very hard to avoided spaces as these things always end up in a URL eventually e.g. "Code Auditor" should be "CodeAuditor". Figure: Product Level - At this level there should be only 3 folders (DEV, RELESE and SAFE) all of which should be in capitals. These folders represent the three stages of your application production line. Each of them may contain multiple branches but this format leaves all of your branches at the same level. Figure: The DEV folder is where all of the Development branches reside. The DEV folder will contain the "Main" branch and all feature branches is they are being used. The DEV designation specifies that all code in every branch under this folder has not been released or made ready for release. And feature branches MUST merge (Forward Integrate) from Main and stabilise prior to merging (Reverse Integration) back down into Main and being decommissioned. Figure: In the Feature branching scenario only merges are allowed onto Main, no development can be done there. Once we have a mature product it is important that new features being developed in parallel are kept separate. This would most likely be used if we had more than one Scrum team working on a single product. Figure: when we are ready to do a release of our software we will create a release branch that is then stabilised prior to deployment. This protects the serviceability of of our released code allowing developers to fix bugs and re-release an existing version. Figure: All bugs found on a release are fixed on the release.  All bugs found in a release are fixed on the release and a new deployment is created. After the deployment is created the bug fixes are then merged (Reverse Integration) into the Main branch. We do this so that we separate out our development from our production ready code.  Figure: SAFE or RTM is a read only record of what you actually released. Labels are not immutable so are useless in this circumstance.  When we have completed stabilisation of the release branch and we are ready to deploy to production we create a read-only copy of the code for reference. In some cases this could be a regulatory concern, but in most cases it protects the company building the product from legal entanglements based on what you did or did not release. Figure: This allows us to reference any particular version of our application that was ever shipped.   In addition I am an advocate of having a single solution with all the Project folders directly under the “Trunk”/”Main” folder and using the full name for the project folders.. Figure: The ideal solution If you must have multiple solutions, because you need to use more than one version of Visual Studio, name the solutions “[Client].[Product][VSVersion].sln” and have it reside in the same folder as the other solution. This makes it easier for Automated build and improves the discoverability of your code and its dependencies. Send me your feedback!   Technorati Tags: VS ALM,VSTS Developing,VS 2010,VS 2008,TFS 2010,TFS 2008,TFBS

• What's better than outputdebugstring for windows debugging?

  - by Peter Turner

  So, before I came to my current place of employment, the windows OutputDebugString function was completely unheard of, everyone was adding debug messages to string lists and saving them to file or doing showmessage popups (not very useful for debugging drawing issues). Now everybody (all 6 of us) is like "What can I say about this OutputDebugString?" and I'm like, "with much power comes much responsibility." I kind of feel as though I've passed a silent but deadly code smell to my colleagues. Ideally we wouldn't have bugs to debug right? Ideally we'd have over 0% code coverage, eh? So as far as petty debugging is concerned (not complete rewriting of a 3 million line Delphi behemoth) what's a better way to use debug running code than just adding OutputDebugString all over?

• Doing "it all from scratch" is different than OS-specifics

  - by Bigyellow Bastion

  Many people tell me that in order to write my own operating system I need to understand the inner-workings of the one I'll be writing it on. That's nonsense. I mean I understand it for education purposes, such as studying the workings of a current OS to gain better knowledge of writing one myself. But the OS I'm writing it on is nothing but my scratchpad offering me software to write the code in, and software to assemble/compile my code into executable instructions. I've been told that I need to decide which OS I'm writing it on before I write it, but all I need is an assembler to produce flat binary, or a compiler to produce object code and a linker to link it into a flat binary .bin file. Why do people say it matters which OS you make an OS on, when it doesn't?

  One of the greatest feature in Windows 8 apps is the ability to stream the video/photos/music you’re playing to any DLNA capable device in your network. Meaning that if you’re watching a movie on Netflix on your brand new Surface tablet in your garden, you can continue to watch it without interruption on your TV if you decide to go back inside ! Isn’t that awesome? The best thing is that it takes very few lines to implement that in an app and it’s very easy. You just have to subscribe to one event and feed the EventArgs with the stream you want to display. You can either stream a video/music from a MediaElement/MediaPlayer (see PlayerFramework on CodePlex) or from a simple Image control. Code’s better than text so I invite you to go the sample code of the PlayTo feature on the msdn (it features code for JS, C# and C++). So if you’re developing an app capable of playing video, music or just display some photos, please implement the PlayTo, it will bring a plus to your app.

• Remote Development With Solaris Studio

  - by rchrd

  A new technical article has been published on OTN: How to Develop Code from a Remote Desktop with Oracle Solaris Studio by Igor Nikiforov This article describes the remote desktop feature of the Oracle Solaris Studio IDE, and how to use it to compile, run, debug, and profile your code running on remote servers. Published May 2012 Introducing the IDE Desktop Distribution Determining Whether You Need the Desktop Distribution Creating the Desktop Distribution Using the Desktop Distribution See Also About the Author Introducing the IDE Desktop Distribution Sun Studio 12 Update 1 introduced a unique remote development feature that allows you to run just one instance of the IDE while working with multiple servers and platforms. For example, you could run the IDE on an x86-based laptop or desktop running Oracle Linux, and use a SPARC-based server running Oracle Solaris 10 to compile, run, debug, and profile your code. The IDE works seamlessly just as if you had the Oracle Solaris operating system on your laptop or desktop. ....read more

• How to flip a BC6/BC7 texture?

  - by postgoodism

  I have some code to load DDS image files into OpenGL textures, and I'd like to extend it to support the BC6 and BC7 compressed formats introduced in D3D11. Since DirectX and OpenGL disagree about whether a texture's origin is in the upper-left or lower-left corner, my DDS loader flips each image's pixels along the Y axis before passing the pixels to OpenGL. Flipping compressed textures presents an additional wrinkle: in addition to flipping each row of 4x4-pixel blocks, you also need to flip the pixels within each block. I found code here to flip BC1/BC2/BC3 blocks, and from the block diagrams on MSDN it was easy to adapt the BC3-flipping code to handle BC4 and BC5. The BC6 and BC7 formats look significantly more intimidating, though. Is there a similar bit-twiddling trick to flip these formats, or would I have to fully decompress and recompress each block?

• Should I update blog posts or rewrite them as technology (and me) changes?

  - by Rachel

  I started a programming blog earlier this year, and since I started it some things have changed. Some changes are due to technology changing, some changes are due to my code libraries improving, and some (ok, probably most) are due to me changing as I learn more. I want to go back and completely re-write certain blog posts. Is it better to rewrite posts to remove old information and update them with new stuff, or to create entirely new posts and possibly take down old ones? I'm not talking about small changes to the code, or an extra few sentences, but complete rewrites with new code, new information, etc. Some things to consider are comments on the post, subscribers who receive updates when new posts are created, and user bookmarks.

  - by Mysticgeek

  If you have an Amazon S3 account you’re using to backup your data, you might want an easy way to manage it. CloudBerry Explorer is a free app that runs on your desktop an provides an easy way to manage your S3 account. Installation and Setup Just download and install the application with the defaults.

Now you will want to set up your Amazon S3 account. Click on File \ Amazon S3 Accounts. Double-click on the New Account icon.   Next enter in your Amazon account Access and Secret keys, select SSL if you want, then click the Test Connection button. Provided everything was entered correctly, you’ll see the Connection Success screen, just close out of it. Browse and Manage files Once you have your account setup through the Explorer, you can start viewing and managing your files on S3.

It’s very easy to use, and you can drag and drop files from your computer to the S3 account or vice versa. There is also the ability to transfer files between Amazon S3 accounts from within the explorer.

• Sending email notifications to users

  - by Web Girl

  What is the preferable way to send email notifications to users? I can do it both ways but what is better? have some c# code that calls stored procedure in the database. Stored procedure based on some logic pulls all the emails data and sends email using database mail or c# code calls stored procedure, gets all the nesessary data back and sends email itself using smtp server etc. I just wonder what is the preferable way in the sense of performance etc... C# code is a library that would be a part of the web application. So it's where it's better to put the load, on the application server or the database server? System will not be crazy busy, it's not like Amazon or something. But still it would be nice to create something that makes sense.
