  • How to adopt scrum agile methodology for a small .Net team

    - by Thabo
    I am working on a small product based company developing .Net applications. There is a small team with 5-6 developers. I am a person responsible for planning everything. But my primary role is Software developer. Now our current project is very unstable because of poor organization. Today my boss called me and told to submit a report about required resources, appropriate methodology, required man power and their salary scales to make the current project success. I know I don’t have enough organization skills and I need to go deep in my programming skills. So I need to focus only in the development. So I can’t manage the project anymore. Now I am searching some other ways to make ongoing development success. My questions are What is the suitable agile methodology to my team? Is Scrum is suitable for above mentioned scenario? If we adopt Scrum, what we have to do next? (I think hiring new one to manage the project is more suitable. So we have to get Scrum master and some other developers.) Are there any resources (books, Blogs and etc) to get some tips and advices to solve this problem? If Scrum is not a suitable methodology for our scenario, what else can be more suitable methodology to adopt? Can anyone give a good solution for my problem?

  • How to remove a box2d body when collision happens?

    - by Ayham
    I’m still new to java and android programming and I am having so much trouble Removing an object when collision happens. I looked around the web and found that I should never handle removing BOX2D bodies during collision detection (a contact listener) and I should add my objects to an arraylist and set a variable in the User Data section of the body to delete or not and handle the removing action in an update handler. So I did this: First I define two ArrayLists one for the faces and one for the bodies: ArrayList<Sprite> myFaces = new ArrayList<Sprite>(); ArrayList<Body> myBodies = new ArrayList<Body>(); Then when I create a face and connect that face to its body I add them to their ArrayLists like this: face = new AnimatedSprite(pX, pY, pWidth, pHeight, this.mBoxFaceTextureRegion); Body BoxBody = PhysicsFactory.createBoxBody(mPhysicsWorld, face, BodyType.DynamicBody, objectFixtureDef); mPhysicsWorld.registerPhysicsConnector(new PhysicsConnector(face, BoxBody, true, true)); myFaces.add(face); myBodies.add(BoxBody); now I add a contact listener and an update handler in the onloadscene like this: this.mPhysicsWorld.setContactListener(new ContactListener() { private AnimatedSprite face2; @Override public void beginContact(final Contact pContact) { } @Override public void endContact(final Contact pContact) { } @Override public void preSolve(Contact contact,Manifold oldManifold) { } @Override public void postSolve(Contact contact,ContactImpulse impulse) { } }); scene.registerUpdateHandler(new IUpdateHandler() { @Override public void reset() { } @Override public void onUpdate(final float pSecondsElapsed) { } }); My plan is to detect which two bodies collided in the contact listener by checking a variable from the user data section of the body, get their numbers in the array list and finally use the update handler to remove these bodies. The questions are: Am I using the arraylist correctly? How to add a variable to the User Data (the code please). I tried removing a body in this update handler but it still throws me NullPointerException , so what is the right way to add an update handler and where should I add it. Any other advices to do this would be great. Thanks in advance.

  • How do I get my programs to communicate with each other

    - by Benjamin Lindqvist
    I'm basically just getting started with programming. The problem I have with progressing is that I have a hard time learning stuff just for the sake of knowing them - I do better when there's a problem to be solved or a task to be completed so I can learn 'on the job'. So I'm interested in starting some interesting project. I know the basics of Python, Java, Matlab and some C++ aswell and I know enough about microcontrollers to make LED blink etc. The type of stuff I'm looking for is for example scraping some weather forecast site (with Python) and outputting the chance of rain to a LCD display, or a program that makes chrome open and log in to facebook if I say "HAL, time for facebook", or more generally, a program that reads serial/USB input, looks for certain sequences and sends instructions to some other program if it finds one. Do you open some kind of shared stream in which one program reads and one writes? What do I need to read up on to do accomplish this myself? I have no experience with linux or the linux terminal, but looking over peoples shoulders makes me suspect that's what people use. Is that correct?

  • What are the most necessary non-language specific things a programmer needs to know?

    - by Josh
    I've been thinking about this a lot lately. Right now I work at a little web company, am almost done with school, and have written an iPhone app, but I'm not sure what else I need to focus my learning energies on. I've decided I want to do software programming, so I've been actively reading everything I can get my hands on that deals with Objective-C / C++ (Cocoa, OpenGL, etc). But those are not the things I'm talking about. I know I need to "master" a language or two. What I'm talking about are the other "things". Things such as learning and using source control, design patterns, etc. What thing (or things, just one per response), would you say I should concurrently be focusing on? You can consider in your answer that I'm wanting to do the aforementioned career path, but you don't have to. I just want a nice list of things to research, and actually use in my career. Also, can someone help me with tagging this? I'm not sure what exactly would be a good tag for such a question.

  • What are some efficient ways to set up my environment when working on a remote site?

    - by Prefix
    Hello fellow Programmers, I am still a relatively new programmer and have recently gotten my first on-campus programming position. I am the sole dev responsible for 8 domains as well as 3 small sized PHP web apps. The campus has its web environment divided into staging and live servers -- we develop on the staging via SFTP and then push the updates to the live server through a web GUI. I use Sublime Text 2 and the Sublime SFTP plugin currently for all my dev work (its my preferred editor). If I am just making an edit to a page I'll open that individual file via the ftp browser. If I am working on the PHP web app projects, I have the app directory mapped to a local folder so that when I save locally the file is auto-uploaded through Sublime SFTP. I feel like this workflow is slow and sub-optimal. How can I improve my workflow for working with remote content? I'd love to set up a local environment on my machine as that would eliminate the constant SFTP upload/download, but as I said there are many sites and the space required for a local copy of the entire domain would be quite large and complex; not to mention keeping it updated with whatever the latest on the staging server is would be a nightmare. Anyone know how I can improve my general web dev workflow from what I've described? I'd really like to cut out constantly editing over FTP but I'm not sure where to start other than ripping the entire directory and dumping it into XAMP.

  • Genetic Algorithm new generation exponentially increasing

    - by Rdz
    I'm programming Genetic Algorithm in C++ and after searching all kind of ways of doing GA'a operators (selection, crossover, mutation) I came up with a doubt. Let's say I have an initial population of 500. My selection will consist in getting the top 20% of 500(based on best fitness). So I get 100 individuals to mate. When I do the crossover I'll get 2 children where both together have 50% of surviving. So far so good. I start the mutation, and everything's ok.. Now when I start choosing the Next generation, I see that I have a big number of children (in this case, 4950 if you wanna know). Now the thing is, every time I run GA, if I send all the children to the next generation, the number of individuals per generation will increase exponentially. So there must be a way of choosing the children to fulfill a new generation without getting out of this range of the initial population. What I'm asking here is if there is anyway of choosing the children to fill the new generations OR should I choose somehow (and maybe reduce) the parents to mate so I don't get so many children in the end. Thanks :)

  • SharePoint 2010 in the cloud a.k.a. SharePoint Online

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). There are 3 ways to run SharePoint On premises, you buy the servers, and you run the servers. Hosted servers, where you don’t run the servers, but you let a hosting company run dedicated servers. Multi-tenant, like SharePoint online – this is what I am talking about in this blog post. Also known as SaaS (Software as a Service). The advantages of a cloud solution are undeniable. Availability, (SharePoint line offers a 99.9% uptime SLA) Reliability. Cost. Due to economies of scale, and no need to hire specialized dedicated staff. Scalability. Security. Flexibility – grow or shrink as you need to. If you are seriously considering SharePoint 2010 in the cloud, there are some things you need to know about SharePoint online. What will work - OOTB Customization, collaboration features etc. will work SharePoint Designer 2010 is supported, so no code workflows will work Visual Studio sandbox solutions, client object model will work. What won’t work - SharePoint 2010 online cloud environment supports only sandbox solutions. BCS, business connectivity services is not supported in SharePoint online. What you can do however is to host your services in Azure, and call them using Silverlight. Custom timer jobs will not work. Long story short, get used to Sandbox solutions – and the new way of programming. Sandbox solutions are pretty damn good. Most of the complaints I have heard around sandbox solutions being too restrictive, are uninformed mechanisms of doing things mired in the ways of 2002. .. or you could just live in 2002 too.

  • Algorithm to match timestamped events from two sources

    - by urza.cc
    I have two different physical devices (one is camera, one is other device) that observe the same scene and mark when a specified event occures. (record timestamp) So they each produce a serie of timestamps "when the event was observed". Theoretically the recorded timestamps should be very well aligned: Visualized ideal situation on two time lines "s" and "r" as recorded from the two devices: but more likely they will not be so nicely aligned and there might be missing events from timeline s or r: I am looking for algorithm to match events from "s" and "r" like this: So that the result will be something like: (s1,null); (s2,r1); (s3,null); (s4,r2); (s5,r3); (null,r4); (s6,r5); Or something similar. Maybe with some "confidence" rating. I have some ideas, but I feel that this might be probably a well known problem, that has some good known solutions, but I don't know the right terminology. I am a little bit out of my element here, this is not my primary area of programming.. Any helps, suggestions etc will be appreciated.

  • Why it is called "hash table", or "hash function"? Hash doesn't make any sense to me here

    - by Saeed Neamati
    It's now about 4 years of development that I'm using, hearing, talking about, and implementing hash tables and hash functions. But I really never understand why it's called hash? I remember the first days I started programming, this term was kind'of cumbersome terminology to me. I never figured out what is it, based on its name. I just experimentally understood what it does and why and when should we use it. However, I still sometimes try to figure out why it's called hash. I have no problem with table or function and to be honest, they are pretty deductive, rational terms. However, I think better words could be used instead of hash, like key, or uniqueness. Don't key table or uniqueness table. According to my dictionary, hash means: Fried dish of potato and meats (highly irrelevant) # symbol (AKA number sign, pound sign, etc.) (still irrelevant, maybe just a mis-nomenclature) Apply algorithm to character string (still has nothing to do with uniqueness, which is the most important feature of a hash table) Cut food Another term for hashish Does anyone know why it's called hash?

  • Experienced programmer, beginner at web design, tools for effective maintainable web design? [closed]

    - by Clinton
    I do quite a bit of programming in my work, which I'm comfortable with, but recently I've being trying to do some web-design for non-work related reasons. I've got a Drupal site up and running, and added some content. But they all look fairly basic. Header with some content. It doesn't look particularly polished. Anyway, as an example, what I wanted to do was make some "bubbles", each with some text in them. From a programmers point of view, say: bubble(question_text, answer_text) might expand to a box with some border, with "Question: " + question_text then "Answer: " + answer_text. Of course I'd have lots of these bubbles, but I'd like to change their look and feel in one place, so simple HTML would be a maintainable nightmare. I also want to lay them out on the screen in some fashion. I was thinking a mixture of javascript and CSS, or possibly use PHP which Drupal uses. On the other hand, I fear I might be taking a 1990s approach to this, and that there's actually tools available now that make this process a lot easier. I'm just wondering what the best approach to this sort of task is? Should I be using offline web design software and copying the code to Drupal, and if so, any recommendations? I'm sorry if my question is a bit vague, because I'm not really sure what question I should be asking. I'd appreciate if you answer and comment, and I'll try my best to be more specific as I understand more.

  • How do I finish installing Sun JDK after cancelling out of the legal term screen?

    - by Ravi
    I am a newcomer to linux and have had lots of problems in installing java on my newly installed Ubuntu 11.10. I use a statistical programming environment called R and many of the packages there require java (the sun variety, I am told). I tried the following : sudo add-apt-repository ppa:ferramroberto/java sudo apt-get update sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts (after this, I wanted to continue with (but never got that far) : sudo apt-get install sun-java6-jdk After this, a window appeared with the heading, "Configuring jre", or something like that. Below was a long list of legal text about accepting Sun's terms. I did not know how to close this window (no obvious option like pressing return worked). After a long time, when nothing seemed to happen, I finally closed the window. After that, I could not open synaptic. I got the error message : dpkg was interrupted. You must manually run 'sudo dpkg --configure -a' I did this. But it does not help. I have java as a "broken" program. When I try to remove the program from synaptic, I get a message that I must reinstall it again.I do not know what I should do. I want to install jdk6. And also remove the open jdk which is still persistently present in my system. I tried the clean and purge command shown below. Next, I tried to remove the sun-java6-jre from synaptic. I get the following message :E: sun-java6-jre: Package is in a very bad inconsistent state - you should reinstall it before attempting a removal. When I tried to follow the procedure suggested in the related question (from the link suggested below), I get the following message on trying to install again :Could not mark all packages for installation or upgrade.The following packages have unresolvable dependancies. Make sure that all required repositories are added and enabled in the preferences. sun-java6-bin : Depends: sun-java6-jre but it is not going to be installed

  • Learning OO for a C Programmer

    - by Holysmoke
    I've been programming professionally in C, and only C, for around 10 years in a variety of roles. As would be normal to expect, I understand the idioms of the language fairly well and beyond that also some of the design nuances - which APIs to make public, who calls what, who does what, what is supposed to reentrant and so on. I grew up reading 'Writing Solid Code', it's early C edition, not the one based on C++. However, I've never ever programmed in an OO language. Now, I want to migrate to writing applications for iPhone (maybe android), so want to learn to use Objective-C and use it with a degree of competence fitting a professional programmer. How do I wrap my head around the OO stuff? What would be your smallest reading list suggestion to me. Is there a book that carries some sort of relatively real world example OO design Objective-C? Besides, the reading what source code would you recommend me to go through. How to learn OO paradigm using Objective-C?

  • You are or will be a laid off programmer - what do you do a year ago, right now, tomorrow, and next week?

    - by Adam Davis
    Many programmers, software engineers, and other technology professionals are out of work, facing layoffs, or are unprepared for layoffs though they feel secure right now. What should every programmer do right now (even if secure in their current job) to prepare them for layoffs down the road? If your boss came to your cubicle while you read this and laid you off: What would you do immediately after? What would you do tomorrow? What would you do next week? It obvious that one should always have an up to date resume, always get recommendations from people when they see you at your best (not when you're looking for a new job), etc. What are the things, step by step, that every programmer should do (or should consider doing) long before they are laid off, when they're laid off, and shortly after being laid off? This is a question with many possible facets. While I want to encourage discussion to center around programming career based answers, please reconsider before downvoting someone because they're thinking in terms of how they're going to prevent going into debt. Bonus catch-22 type question: You can study a new language or technology while out of work, but most places want you to have more than 1-2 months experience in a working environment, not just from a learning exercise. Is it worthwhile to place a priority on new (ideally in demand) skills, or should you instead hone existing skills?

  • How to change careers

    - by Jack Black
    For the past 4 years I have worked in c# doing web development. I have really enjoyed it, learnt a lot and have a worked hard to get to a position where I am earning good money and enjoy the work. However lately - I have wanted a change. What with the "native renaissance" I would like to change my career from being high level application and web development to more down to the metal native development. I haven't done any c or c++ since Uni over 4 years ago and so I have begun reading text books and websites to brush up. However - one major issue I have is that I have no practical experience with C++ and although I am brushing up on it, there will be a lot I don't know. Most of the jobs I have seen in native code around me all require native experience. The only positions I can find that don't explicitly ask for native experience are junior level positions. In my current role I am a mid level developer and although there would be a lot to learn in a c++ position, I wouldn't class myself as a junior. I guess my question is, how do people solve this issue when changing programming languages for their profession and / or how would you approach this hurdle? Like I said, I would really like to try out native development professionally but I wouldn't want to move back to a junior role. Would employers consider years of managed development and native hobby projects enough experience?

  • Removing ocurrances of characters in a string

    - by DmainEvent
    I am reading this book, programming Interviews exposed by John Wiley and sons and in chapter 6 they are discussing removing all instances of characters in a src string using a removal string... so removeChars(string str, string remove) In there writeup they sey the steps to accomplish this are to have a boolean lookup array with all values initially set to false, then loop through each character in remove setting the corresponding value in the lookup array to true (note: this could also be a hash if the possible character set where huge like Unicode-16 or something like that or if str and remove are both relatively small... < 100 characters I suppose). You then iterate through the str with a source and destination index, copying each character only if its corresponding value in the lookup array is false... Which makes sense... I don't understand the code that they use however... They have for(src = 0; src < len; ++src){ flags[r[src]] == true; } which is turning the flag value at the remove string indexed at src to true... so if you start out with PLEASE HELP as your str and LEA as your remove you will be setting in your flag table at 0,1,2... t|t|t but after that you will get an out of bounds exception because r doesn't have have anything greater than 2 in it... even using there example you get an out of bounds exception... Am is there code example unworkable?

  • Solution for lightweight LAN peer discovering?

    - by DevilWithin
    I built a library for purely cross-platform programming. My games made with it run fine in Android , Pc, Linux, Mac etc. The networking capabilities are provided by ENET library, therefore all communication between my apps is not TCP or UDP compatible, but only in the custom protocol, even tough its based on the UDP ultimately. I don't think its possible to do what i want with ENET, thats why I ask here for help! Lets say I have the same game running in my Android phone, my laptop and my pc. They are all in the same wifi network, and therefore in a LAN, whether its Wifi hotspot(?) or the household router. I need each of those 3 peers to discover the other two in the network. This is meant only to find the IP of alive apps in the LAN network, to be able to host multiplayer games between them. I can only think of one effective way to do this, UDP broadcast, wait responses, but if that is the solution, i need something small, since its the only purpose of the implementation. Other way could be to try to connect to all IPs in the LAN address subrange, but I don't think the OS would be with me on this one :p Sorry for the long question!

  • Is a big name computer science degree worth the cost?

    - by Serplat
    I'm currently in High School and trying to look into what I want to do after I graduate. I know that I will be going to college, and that I want a degree in Computer Science, however, I'm not entirely sure where I want to go (I haven't started the application process yet). I already have built up a decent amount of experience in programming (over the summers I have been hired to program at a local university), and I'm pretty capable of teaching myself most of the material I've come across through either books or web documentation. I'm interested in whether it is worth it to get a degree from a major, big-name computer science university for $50,000 each year, as opposed to going to a local state school for only $20,000. For my Bachelor's degree alone, this would be $120,000 more than the state school. I've also heard that where you get your Bachelor's doesn't matter much if you plan to get a Master's degree. Many people recommend going somewhere like a state school for your Bachelor's, and then try to get into a more major school for your Master's. Has anybody found any truth in this? Basically, is going to a big name computer science school for a Bachelor's degree really worth the added expense?

  • Tomcat + Spring + CI workflow

    - by ex3v
    We're starting our very first project with Spring and java web stack. This project will be mainly about rewriting quite large ERP/CRM from Zend Framework to Java. Important factor in my question is that I come from php territory, where things (in terms of quality) tend to look different than in java world. Fatcs: there will be 2-3 developers, at least one of developers uses Windows, rest uses Linux, there is one remote linux-based machine, which should handle test and production instances, after struggling with buggy legacy code, we want to introduce good programming and development practices (CI, tests, clean code and so on) client: internal, frequent business logic changes, scrum, daily deployments What I want to achieve is good workflow on as many development stages as possible (coding - commiting - testing - deploying). The problem is that I've never done this before, so I don't know what are best practices to do this. What I have so far is: developers code locally, there is vagrant instance on every development machine, managed by puppet. It contains the same linux, jenkins and tomcat versions as production machine, while coding, developer deploys to vagrant machine, after local merge to test branch, jenkins on vagrant handles tests, when everything is fine, developer pushes commits and merges jenkins on remote machine pulls commit from test branch, runs tests and so on, if everything looks green, jenkins deploys to test tomcat instance Deployment to production is manual (altough it can be done using helping scripts) when business logic is tested by other divisions and everything looks fine to client. Now, the real question: does above make any sense? Things that I'm not sure about: Remote machine: won't there be any problems with two (or even three, as jenkins might need one) instances of same app on tomcat? Using vagrant to develop on php environment is just vise. Isn't this overkill while using Tomcat? I mean, is there higher probability that tomcat will act the same on every machine? Is there sense of having local jenkins on vagrant?

  • Automatic Generalization

    - by Nick Harrison
    I have been interested in functional programming since college. I played around a little with LISP back then, but I have not had an opportunity since then. Now that F# ships standard with VS 2010, I figured now is my chance. So, I was reading up on it a little over the weekend when I came across a very interesting topic. F# includes a concept called "Automatic Generalization". As I understand it, the compiler will look at your method and analyze how you are using parameters. It will automatically switch to a generic parameter if it is possible based on your usage. Wow! I am looking forward to playing with this. I have long been an advocate of using the most generic types possible especially when developing library classes. Use the highest level base class that you can get away with. Use an interface instead of a specific implementation. I don't advocate passing object around, but you get the idea. Tools like resharper, fxCop, and most static code analysis tools provide guidance to help you identify when a more generalized type is possible, but this is the first time I have heard about the compiler taking matters into its own hands. I like the sound of this. We'll see if it is a good idea or not. What are your thoughts? Am I missing the mark on what Automatic Generalization does in F#? How would this work in C#? Do you see any problems with this?

  • Html 5 clock, part ii - CSS marker classes and getElementsByClassName

    - by Norgean
    The clock I made in part i displays the time in "long" - "It's a quarter to ten" (but in Norwegian). To save space, some letters are shared, "sevenineight" is four letters shorter than "seven nine eight". We only want to highlight the "correct" parts of this, for example "sevenineight". When I started programming the clock, each letter had its own unique ID, and my script would "get" each element individually, and highlight / hide each element according to some obscure logic. I quickly realized, despite being in a post surgery haze, …this is a stupid way to do it. And, to paraphrase NPH, if you find yourself doing something stupid, stop, and be awesome instead. We want an easy way to get all the items we want to highlight. Perhaps we can use the new getElementsByClassName function? Try to mark each element with a classname or two. So in "sevenineight": 's' is marked as 'h7', and the first 'n' is marked with both 'h7' and 'h9' (h for hour). <div class='h7 h9'>N</div><div class='h9'>I</div> getElementsByClassName('h9') will return the four letters of "nine". Notice that these classes are not backed by any CSS, they only appear directly in html (and are used in javascript). I have not seen classes used this way elsewhere, and have chosen to call them "marker classes" - similar to marker interfaces - until somebody comes up with a better name.

  • I've inherited 200K lines of spaghetti code -- what now?

    - by kmote
    I hope this isn't too general of a question; I could really use some seasoned advice. I am newly employed as the sole "SW Engineer" in a fairly small shop of scientists who have spent the last 10-20 years cobbling together a vast code base. (It was written in a virtually obsolete language: G2 -- think Pascal with graphics). The program itself is a physical model of a complex chemical processing plant; the team that wrote it have incredibly deep domain knowledge but little or no formal training in programming fundamentals. They've recently learned some hard lessons about the consequences of non-existant configuration management. Their maintenance efforts are also greatly hampered by the vast accumulation of undocumented "sludge" in the code itself. I will spare you the "politics" of the situation (there's always politics!), but suffice to say, there is not a consensus of opinion about what is needed for the path ahead. They have asked me to begin presenting to the team some of the principles of modern software development. They want me to introduce some of the industry-standard practices and strategies regarding coding conventions, lifecycle management, high-level design patterns, and source control. Frankly, it's a fairly daunting task and I'm not sure where to begin. Initially, I'm inclined to tutor them in some of the central concepts of The Pragmatic Programmer, or Fowler's Refactoring ("Code Smells", etc). I also hope to introduce a number of Agile methodologies. But ultimately, to be effective, I think I'm going to need to hone in on 5-7 core fundamentals; in other words, what are the most important principles or practices that they can realistically start implementing that will give them the most "bang for the buck". So that's my question: What would you include in your list of the most effective strategies to help straighten out the spaghetti (and prevent it in the future)?

  • Transition from 2D to 3D Game development [closed]

    - by jakebird451
    I have been working in the 2D world for a long time from manual blitting in windows to SDL to Python (pygame, pyopengl) and a bunch in between. Needless to say I have been programming for a while. So a while ago I started to program in OpenGL via C++ on my Mac. I then got a little intricate with my work after a while (3D models with skeleton structure and terrain development). After a long time of tinkering, I stopped due to the heavy work just to yield a low level understanding of how OpenGL works. Still interested in Graphics and Game Development I went on a search for a stable game engine with some features to grow on. Licence Requirement: Anything other than GPL (LGPL will do) OS Requirement: Mac & Windows Shader: GLSL or CG (GLSL preferred due to experience) Models: Any model structure with rigging (bone) support & animation I am looking at http://www.ogre3d.org/ currently and am starting to meddle around with some examples. However I am a little reluctant to spend a lot of time on it only to yield another dead end. So instead of falling down a spiraling black pit, I am posting my question to you guys to lead me in the right direction based on my requirements. How was your experience with the engine you recommend? Is it well documented? Does it have well documented examples? Any library requirements (Boost, libpng, etc)?

  • Secure Coding Practices in .NET

    - by SoftwareSecurity
    Thanks to everyone who helped pack the room at the Fox Valley Day of .NET.   This presentation was designed to help developers understand why secure coding is important, what areas to focus on and additional resources.  You can find the slides here. Remember to understand what you are really trying to protect within your application.  This needs to be a conversation between the application owner, developer and architect.  Understand what data (or Asset) needs to be protected.  This could be passwords, credit cards, Social Security Numbers.   This also may be business specific information like business confidential data etc.  Performing a Risk and Privacy Assessment & Threat Model on your applications even in a small way can help you organize this process. These are the areas to pay attention to when coding: Authentication & Authorization Logging & Auditing Event Handling Session and State Management Encryption Links requested Slides Books The Security Development Lifecycle: SDL: A Process for Developing Demonstrably More Secure Software Threat Modeling Writing Secure Code The Web Application Hackers Handbook  Secure Programming with Static Analysis   Other Resources: OWASP OWASP Top 10 OWASP WebScarab OWASP WebGoat Internet Storm Center Web Application Security Consortium Events: OWASP AppSec 2011 in Minneapolis
