• Why choose an established CMS as opposed to building one from scratch?

  - by SkonJeet

  A lot of my research over the next few weeks will be into different CMS's. I've already had a brief look at episerver and umbraco. While reading into these systems I can't help but think that providing content management features are achievable without learning the details and structure of many of these (rather large) CMS platforms. I have, in the past, been given projects whereby my role as a developer must be kept separate to that of an editor (makes sense). i.e. It was my task to develop the design and functionality of the site and my clients' job to update the content. I've achieved this by also implementing a sort of 'portal' on which there were a couple of pages that would accept text input and picture uploads etc. (basically, whatever content they wanted), record this new content to the database and then by design the code-behind would read all this from the database into relevant controls (repeaters for example). For me, this has been an effective enough way of my clients managing the content to deploy with my solutions. I know that I am wrong - and that CMS's are preferable to those that are built from the ground up - but other than the matter of cost, why?

• Use constructor or setter method?

  - by user633600

  I am working on a UI code where I have an Action class, something like this - public class MyAction extends Action { public MyAction() { setText("My Action Text"); setToolTip("My Action Tool tip"); setImage("Some Image"); } } When this Action class was created it was pretty much assumed that the Action class wont be customizable (in a sense- its text, tooltip or image will be not be changed anywhere in the code). Of late, now we are in need of changing the action text at some location in code. So I suggested my co-worker to remove the hardcoded action text from the constructor and accept it as an argument, so that everybody is forced to pass the action text. Something like this code below - public class MyAction extends Action { public MyAction(String actionText) { setText(actionText); setTooltip("My Action tool tip); setImage("My Image"); } } He however thinks that since setText() method belongs to base class. It can be flexibly used to pass the action text wherever action instance is created. That way, there is no need to change the existing MyAction class. So his code would look something like this. MyAction action = new MyAction(); //this creates action instance with the hardcoded text action.setText("User required new action text"); //overwrite the exisitng text. I am not sure if that is a correct way to deal with problem. I think in above mentioned case user is anyway going to change the text, so why not force him while constructing the action. The only benefit I see with the original code is that user can create Action class without much thinking about setting text.

• Form development optimization

  - by Juan

  Like many web developers I do forms all the time. I found myself doing the same all the time: placing input fields, assigning a name to each, ajax the form, then create the PHP which involves to assign a PHP var to each $_REQUEST['var'], escape and validate data, build the html and emailing the results. So I found that 70% of the work is duplicated but I just can't duplicate a page and change the fields. I end up wasting more time reformatting, deleting and adding different fields than creating from scratch. I started planing to program a "list of IDs to html+php" converter in which I'd input all the IDs and this would output the basic html and php. Then I thought: there's got to be thousands of developers that go through this, I'd be reinventing the wheel. So this is my question, I'm trying to find that wheel that somebody must have invented already. I found this: http://www.trirand.com/blog/jqform/ which does more or less what I'm looking for but it's an expensive solution and it has too much functionality for what I'd be using it. Which tools do you use to optimize repetitive task about HTML and PHP?

• Efficient Algorithm for Recording gameplay's objects positions

  - by Scorch

  So, I have a game idea in mind, and for that I need to record the game around the player. I'me not talking about recording it as video, but rather recording the scene objects, and their positions within the game, and then render them, giving the player the ability to go back and forth, to stop time and move around. I've made a prototype with some data structures in C#, since this is going to be the programming language we'll be using in our game, but if we want the player to be able to go back just five minutes back with the data of just 100 NPC's, it takes almost 1GB of RAM. Right now, I'm just storing a Doubly linked list, each item with the object position. In the game, I'll need to store even more data in each node, so I need something even more ligher. Of course, this algorithm is zero optimized, but still, that is a lot. The alternatives would be create the NPC's that aren't really important to the game when the user is viewing the past, but I don't really like it very much for the sake of realism. I wonder if there is a better way to store this? Thanks in advance, Scorch

• Why don't windows of the same application behave as they should in Oneiric?

  - by Yuttadhammo

  Somewhere along the upgrade path, Unity has developed some strange logic behind window layering. First, before Oneiric, there was a way to see all the windows of an application - I think it was when you click on the icon in the launcher. Now, clicking on the icon often does nothing. Suppose I have two terminals open, one behind this Firefox window, and one in front of it. Clicking on the launcher does nothing - the only way to find the second terminal, afaics, is to move the Firefox window or use the task switcher (which has a whole slew of problems of its own). Secondly, once I have both terminals on top, then I decide to close one of them, suddenly they both disappear (the second one, for some reason, has gone into hiding behind the Firefox window). Third (though I can't pin it down now), sometimes when a window is on top, focus is still on a window in back; I click on the top x to close the window in front, only to find I've closed an important window in the back. I can't really believe these are bugs, since they seem too obvious to not have been fixed by now. My question is, am I missing something? Some compiz option I can set to make it act like it used to? Or is this really how Unity is supposed to act?

• Free movement in a tile-based isometric game

  - by xtr486

  Is there a reasonable easy way to implement free movement in a tile-based isometric game? Meaning that the player wouldn't just instantly jump from one tile to another or not be "snapped" to the grid (for example, if the movement between tiles were animated but you'd be locked from doing anything before the animation finishes). I'm a really beginner with anything related to game programming, but with the help of this site and some other resources it was quite easy to do the basic stuff, but I haven't been able to find any useful resources for this particular problem. Currently I've improvised something close to this: http://jsfiddle.net/KwW5b/4/ (WASD movement). The idea for the movement was to use the mouse map to detect when the player has moved to a different tile and then flip the offsets, and for the most part it works correctly (each corner makes the player move to wrong location: see http://www.youtube.com/watch?v=0xr15IaOhrI, which is probably because I couldn't get the full mouse map work properly), but I have no illusions that it is even close to a good/sane solution. And anyway, it's mostly just to demonstrate what kind of a thing I'd like to implement.

• Good resources for learning modern OpenGL (3.0 or later)?

  - by MatterGoal

  I stumble upon the search of a good resource to start with OpenGL (3.0 or later) . Well, I found a lot of books but none of them can be considered a good resource! Here two examples: OpenGL Programming Guide (7th edition) http://www.amazon.com/exec/obidos/ASIN/0321552628/khongrou-20 This is FULL of deprecated material! Almost every chapters begin with a note about that. OpenGL Superbible (5th Edition) http://www.amazon.com/exec/obidos/ASIN/0321712617/khongrou-20 This book uses a library created by the author to explain the main arguments, hiding what you want to learn! I don't want to learn how to use your library! I want to learn OpenGL! I hope that you understand this is not the same question like "hey I'm not able to use Google... tell me how to learn OpenGL". I've just finished a full and deep search but I can't find a good and complete resource to learn the "new" OpenGL avoiding deprecated topics. Can someone heading me in the right direction? I know C++ and I have 10 years of experience in development... where I can find a good resource?! I want to spend time on it and I want to learn deeply. (please feel free to edit my question, my English is terrible!)

• Split up a screen into regions

  - by nexen

  My task: I want to split up a screen into 3 regions for buffs-bar (with picked items), score-info and a game-map. It doesn't matter are regions intersect with each other or not. For example: I have a screen with width=1; height=1 and the origin of coordinates (0;0) is the left bottom point. I have 3 functions: draw items, draw info, draw map. If I use it without any matrix transformations, it draws fullscreen, because it's vertex coordinates are from 0;0 to 1;1. (pseudo-code) drawItems(); drawInfo(); drawMap(); And after that I see only map onto info onto items. My goal: I have some matrixes for transformation vertexes with 0;0-1;1 coordinates to strict regions. There is only one thing, what I need to do - set matrix before drawing. So my call of drawItems-function is like: (pseudo-code) adjustViewMatrixes_andSomethingElse(items.position_of_the_region_there_it_should_be_drawn, items.sizes_of_region_to_draw); setItemsMatrix(); drawItems(); //the same function with vertex coordinates 0;0->1;1, //but it draws in other coordinates, //because I have just set the matrix for region I know only some people will understand me, so there is a picture with regions which I need to make. Every region has 0;0 - 1;1 inner coordinates.

• Hello!

  - by barryoreilly

  After many months of deliberating I have finally gotten around to starting this blog! The reason for doing this is the large number of half finished articles lying around on my hard disk, unpublished and unloved. These articles have been of huge benefit to me, and have been written in an attempt to consolidate my own thinking, in order to help me structure my thoughts and ideas as I have tried to digest new ideas and understand abstract theories. It is my hope that by tidying up these articles and publishing them here that I can continue this learning process by getting feedback on the ideas from within the developer community. i have worked with .NET for 8 years now, and have worked with ASP.NET, SQL Server, Windows programming as well as general network administration. Since 2004 my focus has been on integration, web services, and more often than not Biztalk Server. The last two years have seen me focus on SOA and WCF, and the Managed Services Engine, so this is probably where the main focus of the blog will to start with, but there are so many fun things to play with these days that i have no idea where it will end up.....   Barry

• What are all things that do/can happen when a user enters in a web page's URL?

  - by Job

  Sorry if this is a naive title. I am trying to break into web development, which is so far a foreign world to me. I have taken a basic intro to OS, intro to Networking as part of my bachelors degree several years ago. I cannot say that we went into things deeply, beyond academic assignments. I would like to understand things much better regarding to this specific task (e.g what goes on in at the OS level, at networking level, what are other computers involved, where do proxy servers and hackers come in). Again, at the very basic level this has been covered, but I would like to review this specific thing better. Are there chapter(s) os a specific book, or specific SHORT reading that you recommend? I have nothing against your list of 20 favorite books, but I want to understand this one thing better in 2-3 weeks of reading after work / on the weekends (realistically 5-10 hrs per week, so I am looking for about 15-20 hrs of reading material, NO MORE). I am not a fast reader :) Thanks.

• Is it too late to start your career as a programmer at the age of 30 ?

  - by Matt

  Assuming one graduated college at 30 years old and has 5 years of experience (no real job experience, just contributing to open source and doing personal projects) with various tools and programming languages, how would he or she be looked upon by hiring managers ? Will it be harder to find a job considering that (I got this information looking at various websites, user profiles on SO and here, etc.) the average person gets hired in this field at around 20 years old. I know that it's never too late to do what you're passionate about and the like but sometimes it is too late to start a career. Is this the case? Managers are always looking for fresh people and I often read job descriptions specifically asking for young people. I don't need answers of encouragement, I know the community here is great and I wouldn't get offended by even the most cold answers. Please don't close this as being too localized, I'm not referring to any specific country or region, talk about the region you're in. I would also appreciate if you justified your answer.

• Moving from VB.NET to C#

  - by w0051977

  I have worked with the VB.NET programming language for the last five years. I want to move to C# as I believe skills are more valued plus it is more similar to other object oriented languages like Java. I was offered a job today working primarily with C#. I explained at the interview that I am a VB.NET Developer and I did the test in VB.NET (though they would of preferred C#). If I decide to accept the position then I will be starting at at the top end of the salary bracket (only very slightly more than I earn now). I will have to help more junior staff in the future who probably have more experience using C# than I do (1-2 years). I used Java and C++ at university. I want to move towards C# in the future as I believe C# skills are more valued based on job advertisements I have seen recently. Has anyone else done this and did it work? i.e. move to a new organisation as a C# Developer at quite a senior level with experience primarily using VB.NET.

• Scale an image with unscalable parts

  - by Uko

  Brief description of problem: imagine having some vector picture(s) and text annotations on the sides outside of the picture(s). Now the task is to scale the whole composition while preserving the aspect ratio in order to fit some view-port. The tricky part is that the text is not scalable only the picture(s). The distance between text and the image is still relative to the whole image, but the text size is always a constant. Example: let's assume that our total composition is two times larger than a view-port. Then we can just scale it by 1/2. But because the text parts are a fixed font size, they will become larger than we expect and won't fit in the view-port. One option I can think of is an iterative process where we repeatedly scale our composition until the delta between it and the view-port satisfies some precision. But this algorithm is quite costly as it involves working with the graphics and the image may be composed of a lot of components which will lead to a lot of matrix computations. What's more, this solution seems to be hard to debug, extend, etc. Are there any other approaches to solving this scaling problem?

• Should I avoid or embrace asking questions of other developers on the job?

  - by T.K.

  As a CS undergraduate, the people around me are either learning or are paid to teach me, but as a software developer, the people around me have tasks of their own. They aren't paid to teach me, and conversely, I am paid to contribute. When I first started working as a software developer co-op, I was introduced to a huge code base written in a language I had never used before. I had plenty of questions, but didn't want to bother my co-workers with all of them - it wasted their time and hurt my pride. Instead, I spent a lot of time bouncing between IDE and browser, trying to make sense of what had already been written and differentiate between expected behavior and symptoms of bugs. I'd ask my co-workers when I felt that the root of my lack of understanding was an in-house concept that I wouldn't find on the internet, but aside from that, I tried to confine my questions to lunch hours. Naturally, there were occasions where I wasted time trying to understand something in code on the internet that had, at its heart, an in-house concept, but overall, I felt I was productive enough during my first semester, contributing about as much as one could expect and gaining a pretty decent understanding of large parts of the product. I was wondering what senior developers felt about that mindset. Should new developers ask more questions to get to speed faster, or should they do their own research for themselves? I see benefits to both mindsets, and anticipate a large variety of responses, but I figure new developers might appreciate your answers without thinking to ask this question.

• Managing game objects/components

  - by Xeon06

  Good day everyone, By far the biggest problem that has always dawned on my when programming games is how to structure my code. It just becomes an incredible mess after a while. The reason for that is because I have no idea how different classes should interact with each other. Let's have an example. Say I have a class Player, a class PlayerInput and a class Map. The player class contains information as to the location of the player, whereas the player input class handles changing that location, but by first making sure it's within a walkable area from the map class. How to structure this? My usual approach is to pass those components as parameters in the constructors of the parameters that need them, like so: var map = new Map(); var player = new Player(); var input = new PlayerInput(player, map); The problem with that is that it quickly gets messy, when you add new components you have to go through your constructors and update them, and it doesn't work well if you have mirroring references: var physics = new Physics(input); //Oops, doesn't work var input = new Input(physics); So, how do you guys usually manage this? Thanks.

• How do I get mouse x / y of the world plane in Unity?

  - by Discipol

  I am trying to make a tiled landscape. The terrain itself is not made from tiles but the world has a grid which I define. I would like to place boxes/rectangles which snap to this grid, at runtime, but in order for me to do that I must get a projection from the user screen to the real-world coordinates. I have tried various examples using the Ray class but nothing worked. It compiles and outputs a constant value no matter where I put the mouse. I have tried to add some tiles and try to detect them but no luck. I also tried with one plane as big as my world but still no luck. I am using C# but even a JS version would be helpful. This technique involves calculating which tile the mouse is under by the x and y positions. Perhaps detecting which tile itself is being pointed to would be a simpler task, at which point I can just retrieve its i/j properties. Update: I got it working thanks to some answers, but the ball freaks out towards the far end of the plane. Why is this? https://www.dropbox.com/sh/9pqnl30lm6uwm6h/AACc2JcbW16z6PuHFLLfCAX6a

• In C++ Good reasons for NOT using symmetrical memory management (i.e. new and delete)

  - by Jim G

  I try to learn C++ and programming in general. Currently I am studying open source with help of UML. Learning is my hobby and great one too. My understanding of memory allocation in C++ is that it should be symmetrical. A class is responsible for its resources. If memory is allocated using new it should be returned using delete in the same class. It is like in a library you, the class, are responsibility for the books you have borrowed and you return them then you are done. This, in my mind, makes sense. It makes memory management more manageable so to speak. So far so good. The problem is that this is not how it works in the real world. In Qt for instance, you create QtObjects with new and then hand over the ownership of the object to Qt. In other words you create QtObjects and Qt destroys them for you. Thus unsymmetrical memory management. Obviously the people behind Qt must have a good reason for doing this. It must be beneficial in some kind of way, My questions is: What is the problem with Bjarne Stroustrups idea about a symmetrical memory management contained within a class? What do you gain by splitting new and delete so you create an object and destroy it in different classes like you do in Qt. Is it common to split new and delete and why in such case, in other projects not involving Qt? Thanks for any help shedding light on this mystery!

• Rectangular Raycasting?

  - by igrad

  If you've ever played The Swapper, you'll have a good idea of what I'm asking about. I need to check for, and isolate, areas of a rectangle that may intersect with either a circle or another rectangle. These selected areas will receive special properties, and the areas will be non-static, since the intersecting shapes themselves will also be dynamic. My first thought was to use raycasting detection, though I've only seen that in use with circles, or even ellipses. I'm curious if there's a method of using raycasting with a more rectangular approach, or if there's a totally different method already in use to accomplish this task. I would like something more exact than checking in large chunks, and since I'm using SDL2 with a logical renderer size of 1920x1080, checking if each pixel is intersecting is out of the question, as it would slow things down past a playable speed. I already have a multi-shape collision function-template in place, and I could use that, though it only checks if sides or corners are intersecting; it does not compute the overlapping area, or even find the circle's secant line, though I can't imagine it would be overly complex to implement. TL;DR: I need to find and isolate areas of a rectangle that may intersect with a circle or another rectangle without checking every single pixel on-screen.

• Rotating object around moving object/player in 2D

  - by Boston

  I am trying to implement a camera which rotates around the world around the player. I have found many solutions online to the task of rotating an object about the origin, or about an arbitrary point. The procedure seems to be to translate the point to be rotated about to the origin, perform the rotation, translate back, then draw. I have gotten this working for rotation around the origin as well as for a fixed point. Rotation of objects around the player works as well, provided the player does not move. However, if the objects are rotated around the player by some non-zero degree, if the player moves after the rotation it causes the rotated objects to move as well. I probably have done a poor job explaining this so here's an image: http://i.imgur.com/1n63iWR.gif And here's the code for the behavior: renderx = (Ox - Px)*cos(camAngle) - (Oy - Py)*sin(camAngle) + Px; rendery = (Ox - Px)*sin(camAngle) + (Oy - Py)*cos(camAngle) + Py; Where (Ox,Oy) is the actual position of the object to be rotated and (Px,Py) is the actual position of the player. Any ideas? I am using C++ with SDL2.0.

• Reliance on Outlook (been a looong time, I know)

  - by AndyScott

  Do you feel that your development group too reliant on Outlook? Have you reached a point that you have to search your email for pertinent information when asked? What are you using? I realized things had gotten out of hand a couple weeks ago over a weekend. I was at my in-laws house (in the country, no PC/laptop, no internet connection; and I get an email on my phone that I needed to reply to, but I couldn't send without deleting items from my inbox/sent items/etc. Now mind you, I have rules set up to move stuff into folders, and files more than a month old are automatically moved to the PST; but generally don't manually move items to a PST until I have had a chance to 'work' the item. Please don't bother mocking my process, it's just the way I work. That being said, it was a frustrating process of 'I need all this information, what can I afford to lose'. I work on an International project (think lots of customers), and conversations in 9 or 10 different directions about 10-20 different things are not abnormal for a given day. I have found myself looking data up in Outlook because that's where it is. I think that I have reached the point now, where I don't feel that Outlook is up to the task of organizing the data that it contains.   When you have that many emails (200 or so a day), information seems to get lost at times, and I find that Outlook's search capabilities are lacking. Additionally, I find that any sort of organizational 'system' of sorting emails that can cover multiple topics is a lost cause. But at the same time, the old process of taking the information that I got from emails and moving it into another 'notes' type of program has proved to be too time consuming. Anyone out there have some better type of system? (Comments about the capacity of my brain, and it's ability to recall information not needed.)

• Recommended display/background brightness ratio and UI color schemes [duplicate]

  - by user1306322

  This question already has an answer here: Colour scheme for editor - guidelines or medical reccomendations 3 answers I'm a professional programmer, which means I spend a lot of time staring at various displays. Recently I've been having some problems with my eyes, so I went to talk to several doctors, which all gave me different recommendations as to how bright the background of the room should be in comparison to the display's brightness. It was very confusing, as some of them even agreed with counter-arguments of others, which made it all even less clear. So I'd like to ask the professional programmers, as people who actually have some experience with that. Some of the doctors said that looking at a monitor is like looking at a book, so the brightness ratios should be approximately the same. Others said that background should be as bright as the display itself, because then there is no brightness difference at the edges, and that's what may cause eye fatigue. From my own experience, I can say that reading a book isn't the same as writing or debugging a program, where you have to pay close attention to each symbol, and in books most words are easily recognizable without focusing too hard on them. Also, books are black on white and I myself use the default (dark text, white bg) color scheme for my IDE, but I've seen some programmers use mid-bright text on very dark background color schemes. So I'd like to ask what are the recommended display/background brightness ratios for programming? I'm not sure this site is the right one for this kind of questions, so if you know a better one, please comment.

• Can you recommend a game server for a facebook board game?

  - by Yekmer Simsek

  I am seeking a game server that will scale well. All commercial and/or free software alternatives are welcome. Game will be a boardgame that is similar to poker. Some technical details are listed below. There will be a table which consists of 4 people, to send them message I need a channel manager. A table will be ready to play for at least 5 minutes. There should be a reliable channel manager. People will wait for some time(i.e.) and if they are not playing they will be kicked by server, so there will be a reliable timed task queue to execute some tasks. It should be quick enough to response and show the changes to all 4 people on that table simultaneously.To achive this server should have a powerfull I/O library. I think to use inmemory to have quick response times, but it comes with scalability problems. And some variables should be thread safe so a variable should be thread safe between multiple nodes. Flash(AS3) and Unity (.Net 2.0 C# mono) client API's should be available for socket connection. PS: I am using Reddwarf server, it lacks of documentation and multiple node.

• How to match responses from a server with their corresponding requests? [closed]

  - by Deele

  There is a server that responds to requests on a socket. The client has functions to emit requests and functions to handle responses from the server. The problem is that the request sending function and the response handling function are two unrelated functions. Given a server response X, how can I know whether it's a response to request X or some other request Y? I would like to make a construct that would ensure that response X is definitely the answer to request X and also to make a function requestX() that returns response X and not some other response Y. This question is mostly about the general programming approach and not about any specific language construct. Preferably, though, the answer would involve Ruby, TCP sockets, and PHP. My code so far: require 'socket' class TheConnection def initialize(config) @config = config end def send(s) toConsole("--> #{s}") @conn.send "#{s}\n", 0 end def connect() # Connect to the server begin @conn = TCPSocket.open(@config['server'], @config['port']) rescue Interrupt rescue Exception => detail toConsole('Exception: ' + detail.message()) print detail.backtrace.join('\n') retry end end def getSpecificAnswer(input) send "GET #{input}" end def handle_server_input(s) case s.strip when /^Hello. (.*)$/i toConsole "[ Server says hello ]" send "Hello to you too! #{$1}" else toConsole(s) end end def main_loop() while true ready = select([@conn, $stdin], nil, nil, nil) next if !ready for s in ready[0] if s == $stdin then return if $stdin.eof s = $stdin.gets send s elsif s == @conn then return if @conn.eof s = @conn.gets handle_server_input(s) end end end end def toConsole(msg) t = Time.new puts t.strftime("[%H:%M:%S]") + ' ' + msg end end @config = Hash[ 'server'=>'test.server.com', 'port'=>'2020' ] $conn = TheConnection.new(@config) $conn.connect() $conn.getSpecificAnswer('itemsX') begin $conn.main_loop() rescue Interrupt rescue Exception => detail $conn.toConsole('Exception: ' + detail.message()) print detail.backtrace.join('\n') retry end

• Scala - learning by doing

  - by wrecked

  coming from the PHP-framework symfony (with Apache/MySQL) I would like to dive into the Scala programming language. I already followed a few tutorials and had a look at Lift and Play. Java isn't a stranger to me either. However the past showed that it's easiest to learn things by just doing them. Currently we have a little - mostly ajax-driven - application build on symfony at my company. My idea is to just build a little project similar to this one which might gets into production in the future. The app should feature: High scalability and performance a backend-server web-interface and a GUI-client There are plenty of questions arising when I think of this. First of all: Whats the best way to accomplish a easy to maintain, structured base for it? Would it be best to establish a socket based communication between pure-scala server/client and accessing that data via Lift or is building a Lift-app serving as a server and connecting the gui-client (via REST?) the better way? Furthermore I wounder which database to choose. I'm familiar with (My)SQL but feel like a fool beeing confronted with all these things like NoSQL, MongoDB and more. Thanks in advance!
