• Best practices for managing deployment of code from dev to production servers?

  - by crosenblum

  I am hoping to find an easy tool or method, that allow's managing our code deployment. Here are the features I hope this solution has: Either web-based or batch file, that given a list of files, will communicate to our production server, to backup those files in different folders, and zip them and put them in a backup code folder. Then it records the name, date/time, and purpose of the deployment. Then it sends the files to their proper spot on the production server. I don't want too complex an interface to doing the deployment's because then they might never use it. Or is what I am asking for too unrealistic? I just know that my self-discipline isn't perfect, and I'd rather have a tool I can rely on to do what needs to be done, then my own memory of what exact steps I have to take every time. How do you guys, make sure everything get's deployed correctly, and have easy rollback in case of any mistakes?

• Resources for 2D rendering using OpenGL?

  - by nightcracker

  I noticed that there is quite some difference between 3D and 2D rendering using OpenGL, the techniques are different - pixel-perfect placing is a lot more desirable, among other things. Are there any good (complete) references on using OpenGL for rendering 2D graphics? There are quite a few "tutorials" around on the net that help you open a window, set up a half-decent environment and draw a sprite, but no real good information on rotation, blending, lightning, drawing order, using the z-buffer, particles, "complex" primitives (circles, stars, cross symbols), ensuring pixel-perfect rendering, instancing and many other staple 2D effects/techniques. Any books, great blogs, anything? Any particular awesome libraries to read?

• What are the benefits of designing a KeyBinding relay?

  - by Adam Naylor

  The input system of Quake3 is handled using a Keybinding relay, whereby each keypress is matched against a 'binding' which is then passed to the CLI along with a time stamp of when the keypress (or release) occurred. I just wanted to get an idea from developers what they considered to be the key benefits of designing your input system around this approach? One thing i don't particularly like is the appending of the timestamp to the bound command. This seems like a bit of a hack to bend the CLI into handling the games input? Also I feel that detecting the keypress only to add the command to a stream of text that gets parsed at a later date to be a slightly latent way of responding to input? (or is this unfounded?) The only real benefit i can see is that it allows you to bind 'complex' commands to keypresses; like 'switch weapon;+fire;' for example. Or maybe for journaling purposes? Thanks for any insights!

• How can I create a temporary sandbox to compile from source?

  - by zoopp

  I want to follow the steps found here in order to run League of Legends under Ubuntu. According to the guide, I have to compile wine from source because it needs some patches. Compiling from source involves downloading quite a few dependency packages which I don't want to get mixed with the system and thus I'm wondering if there's a way to somehow isolate the whole "download dependencies packages and compile" process as I am only interested in the final wine binary. By isolating the compile process I can just copy the resulting binary and do a simple delete on the sandbox whereas doing it the naive way would require a more complex cleanup.

• Designing binary operations(AND, OR, NOT) in graphs DB's like neo4j

  - by Nicholas

  I'm trying to create a recipe website using a graph database, specifically neo4j using spring-data-neo4j, to try and see what can be done in Graph Databases. My model so far is: (Chef)-[HAS_INGREDIENT]->(Ingredient) (Chef)-[HAS_VALUE]->(Value) (Ingredient)-[HAS_INGREDIENT_VALUE]->(Value) (Recipe)-[REQUIRES_INGREDIENT]->(Ingredient) (Recipe)-[REQUIRES_VALUE]->(Value) I have this set up so I can do things like have the "chef" enter ingredients they have on hand, and suggest recipes, as well as suggest recipes that are close matches, but missing one ingredient. Some recipes can get complex, utilizing AND, OR, and NOT type logic, something like (Milk AND (Butter OR spread OR (vegetable oil OR olive oil))) and I'm wondering if it would be sane to model this in a graph using a tree type representation? An example of what I was thinking is to create three "node" types of AND, OR, and NOT and have each of them connect to the nodes value underneath. How else might this be represented in a Graph Database or is my example above a decent representation?

• Web and Flex developer career question [closed]

  - by abhilashm86

  Possible Duplicate: should i concentrate on logical and puzzles part in programming, i want to be a web (flex)developer? I'm a computer science student and have been learning Flex and Actionscript 3.0 for 4 months. I know it's easy to program in MXML, and Actionscript 3.0 is pretty easy with bunch of classes, but when I try to code in C++ or C, I struggle, I feel I'm being inefficient and it scares me. Since I'm a student, I've no experience in developing algorithms and tough program solving? I'd like to be a web developer. Does a web developer need strong fundamentals when it comes to things such as complex algorithms and high end coding?

• Should my blog be directly on my website?

  - by steve

  I have my newly launched website at www.slicify.com (redirects to a secure subdomain). I currently have a separate blog on WordPress: slicify.wordpress.com for a couple of reasons: I don't really want to mix my site code (it's a complex ecommerce site written in ASP.Net) with blog code, for ease of maintenance etc. WordPress is already great at blogs - seems silly to reinvent the wheel by trying to integrate blog functionality into my site However is keeping my blog on a separate domain going to hurt me in terms of PageRank or traffic? FWIW: while it's early days, I can see from Google Analytics that a good deal of referral traffic is already coming from my WordPress site to my main site, so at least that seems to be drawing potential users in.

• Help comparing Cocos2d and Unity3d for this project.....

  - by Omega

  I will not go into details, but I would like to hear your opinions about this: Essentially, my project will be a 2d game, with lots of complex levels, where some might be simple and others might be a bit more deep, with physics, etc. We want to implement our very own online structure: logging in, leaderboards, achievements, friends etc with our own servers. This means no OpenFeint nor GameCenter at all. We expect this game to be very large in both graphics and audio. We wish to use in-app purchases. Now, we considered two options. Cocos2d and Unity3d. We need help deciding using the factors I mentioned before (networking, good performance even for a large game in terms of graphics and audio like this, in-app purchases, etc) which option would fit better this? Technically, both options can create 2d games. I'd like to hear your opinion.

• What is the most effective way to add functionality to unfamiliar, structurally unsound code?

  - by Coder

  This is probably something everyone has to face during the development sooner or later. You have an existing code written by someone else, and you have to extend it to work under new requirements. Sometimes it's simple, but sometimes the modules have medium to high coupling and medium to low cohesion, so the moment you start touching anything, everything breaks. And you don't feel that it's fixed correctly when you get the new and old scenarios working again. One approach would be to write tests, but in reality, in all cases I've seen, that was pretty much impossible (reliance on GUI, missing specifications, threading, complex dependencies and hierarchies, deadlines, etc). So everything sort of falls back to good ol' cowboy coding approach. But I refuse to believe there is no other systematic way that would make everything easier. Does anyone know a better approach, or the name of the methodology that should be used in such cases?

• Build one to throw away vs Second-system effect

  - by m3th0dman

  One one hand there is an advice that says "Build one to throw away". Only after finishing a software system and seeing the end product we realize what went wrong in the design phase and understand how we should have really done it. On the other hand there is the "second-system effect" which says that the second system of the same kind that is designed is usually worse than the first one; there are many features that did not fit in the first project and were pushed into the second version usually leading to overly complex and overly engineered. Isn't here some contradiction between these principles? What is the correct view over the problems and where is the border between these two? I believe that these "good practices" are were firstly promoted in the seminal book The Mythical Man-Month by Fred Brooks. I know that some of these issues are solved by Agile methodologies, but deep down, the problem is still the principles still stand; for example we would not make important design changes 3 sprints before going live.

• Transparency in XNA-4 primitives

  - by Shashwat

  I'm using XNA 4 with Visual Studio 2010. I'm trying to create a simple 3D world with walls and doors in which the user to free to roam around. A wall is just a rectangle which is currently being rendered with four vertices using triangle strips. But to create a door, I'd have to split it into three rectangles as shown in the figure. Four quadrilaterals if I want to have the following door-style It will become more complex to have multiple doors on the same wall or if I have windows. Is there any shorter way to handle this? I am looking for something that will just make the wall transparent wherever I want. I found a solution but facing a problem here

• Project development without experience

  - by Raven13

  I'm a web developer who is part of a three-man team that has been tasked with a rather large and complex development project. Other than some direction and impetus from management, we're pretty much on our own to develop the new website. None of us have any project management experience nor do my two coworkers seem like they would be interested in taking on that role, so I feel like it's up to me to implement some kind of structure to the development process in order to avoid issues down the road. My question is: what can I do as a developer without project managment experience to ensure that our project gets developed successfully and avoid the pitfalls of developing a project without a plan?

• how to improve design ability

  - by Cong Hui

  I recently went on a couple of interviews and all of them asked a one or two design questions, like how you would design a chess, monopoly, and so on. I didn't do good on those since I am a college student and lack of the experience of implementing big and complex systems. I figure the only way to improve my design capability is to read lots of others' code and try to implement myself. Therefore, for those companies that ask these questions, what are their real goals in this? I figure most of college grads start off working in a team guided by a senior leader in their first jobs. They might not have lots of design experience fresh out of colleges. Anyone could give pointers about how to practice those skills? Thank you very much

• System Wide Performance Sanity Check Procedures

  - by user702295

  Do you need to boost your overall implementation performance? Do you need a direction to pinpoint possible performance opportunities? Are you looking for a general performance guide? Try MOS note 69565.1.  This paper describes a holistic methodology that defines a systematic approach to resolve complex Application performance problems.  It has been successfully used on many critical accounts.  The 'end-to-end' tuning approach encompasses the client, network and database and has proven far more effective than isolated tuning exercises.  It has been used to define and measure targets to ensure success.  Even though it was checked for relevance on 13-Oct-2008, the procedure is still very valuable. Regards!

• Organizing ASP.Net Single Page Application with Nancy

  - by OnesimusUnbound

  As a personal project, I'm creating a single page, asp.net web application using Nancy to provide RESTful services to the single page. Due to the complexity of the single page, particularly the JavaScripts used, I've think creating a dedicated project for the client side of web development and another for service side will organize and simplify the development. solution | +-- web / client side (single html page, js, css) | - contains asp.net project, and nancy library | to host the modules in application project folder | +-- application / service (nancy modules, bootstrap for other layer) | . . . and other layers (three tier, domain driven, etc) . Is this a good way of organizing a complex single page application? Am I over-engineering the web app, incurring too much complexity?

• How can I tweak this split-tar-gz-archive script?

  - by Sai

  I came across this shell script that can be used to split an entire directory across multiple compressed files. I am interested in making a minor tweak to this script. Lets say I have n GB of files in a directory. I do not want the contents of a particular folder to be split across multiple tar files but inside the same file. I want the n MB folder to be fit within a single compressed file and the remaining (n GB -n MB) split across multiple files. I am not sure whether it is possible with this script. I was looking forward to some suggestions. Though the script has been well documented, it is quite complex to understand for me

• How to explain OOP to a matlab programmer?

  - by Oak

  I have a lot of friends who come from electrical / physical / mechanical engineering background, and are curious about what is "OOP" all about. They all know Matlab quite well, so they do have basic programming background; but they have a very hard time grasping a complex type system which can benefit from the concepts OOP introduces. Can anyone propose a way I can try to explain it to them? I'm just not familiar with Matlab myself, so I'm having troubles finding parallels. I think using simple examples like shapes or animals is a bit too abstract for those engineers. So far I've tried using a Matrix interface vs array-based / sparse / whatever implementations, but that didn't work so well, probably because different matrix types are already well-supported in Matlab.

• What's Your Supply Chain+Manufacturing Strategy for Success

  - by [email protected]

  Forward thinking enterprises look to eliminate their dependence on legacy applications that manage information in batch - replacing them with real-time integrated/modern information managment. With rapid manufacturing and global supply chains much more complex today, with the pace of chance ever increasing, leading organizations need better ways to orchestrate their supply chain synchronization with their partner and customer base. EM magazine Mar/Apr'10 edition, covers this topic in an article "Strategising for Success" pgs 26-27, and discusses the available options to organizations as they drive improvements in the levels of collaboration with their partners, suppliers, shippers, distributors and ultimately their end-users, the customer! I'll past the link to the article here as soon as i validate/confirm it.

• Should I use both WCF and ASP.NET Web API

  - by Mithir

  We already have a WCF API with basichttpbinding. Some of the calls have complex objects in both the response and request. We need to add RESTful abilities to the API. at first I tried adding a webHttp endpoint, but I got At most one body parameter can be serialized without wrapper elements If I made it Wrapped it wasn't pure as I need it to be. I got to read this, and this (which states "ASP.NET Web API is the new way to build RESTful service on .NET"). So my question is, should I make 2 APIs(2 different projects)? one for SOAP with WCF and one RESTful with ASP.NET Web API? is there anything wrong architecturally speaking with this approach?
