• What have you learnt that has a steep learning curve?

  - by Jonathan Khoo

  Recently, I've invested time in learning the intricacies of Git and it has got me thinking about time and learning. (My previous experience with version control systems was only limited use of CVS and SVN.) It took me a whole day's worth of reading to be able to understand the concepts and differences of Git. There are an infinite number of things available for us to learn. Some, more useful than others. I don't know Fortran - I'm relatively young. But looking back at the preceding years of my life, I notice that I'm busier and busier as time goes on. The amount of things I have to get through in a day is increasingly out of my control. It doesn't take a genius to extrapolate that information and realise I'll have even less time in the future - unless I get fired, but I have no strong plans relating to that idea for now. So, given that I have much more time and energy now than I will have in the future: what have you learnt, that has a steep learning curve, that you would possibly recommend to a fellow programmer? Edit: I've stumbled upon the excellent question What programming skills have provided you the best return on investment? and hav realised that my way of approaching how to spend learning time was naive - it doesn't matter if ten useful concepts can be learnt in the time of one if they're worth it.

• Correct For Loop Design

  - by Yttrill

  What is the correct design for a for loop? Felix currently uses if len a > 0 do for var i in 0 upto len a - 1 do println a.[i]; done done which is inclusive of the upper bound. This is necessary to support the full range of values of a typical integer type. However the for loop shown does not support zero length arrays, hence the special test, nor will the subtraction of 1 work convincingly if the length of the array is equal to the number of integers. (I say convincingly because it may be that 0 - 1 = maxval: this is true in C for unsigned int, but are you sure it is true for unsigned char without thinking carefully about integral promotions?) The actual implementation of the for loop by my compiler does correctly handle 0 but this requires two tests to implement the loop: continue: if not (i <= bound) goto break body if i == bound goto break ++i goto continue break: Throw in the hand coded zero check in the array example and three tests are needed. If the loop were exclusive it would handle zero properly, avoiding the special test, but there'd be no way to express the upper bound of an array with maximum size. Note the C way of doing this: for(i=0; predicate(i); increment(i)) has the same problem. The predicate is tested after the increment, but the terminating increment is not universally valid! There is a general argument that a simple exclusive loop is enough: promote the index to a large type to prevent overflow, and assume no one will ever loop to the maximum value of this type.. but I'm not entirely convinced: if you promoted to C's size_t and looped from the second largest value to the largest you'd get an infinite loop!

• Best way to convert existing project to be open source in GitHub

  - by Tom

  I've been working on a personal closed source project for some time and would like to make it open source. I've never created my own open source project before so it will be a good learning experience. I have been using GitHub as source control, so once I've written some decent docs on how to use and develop for it etc, it should be as simple as switching the repo to be public right? I guess my main question is around licencing. I was thinking of going with Apache 2.0 licence just because it seems to be widely used. It requires the licence header to be attached to all the source files, but if I do that now then all the other commits in the past will have it missing. Does that mean some one could pull an earlier version and it wouldn't have a licence? Is it best to start a new repo with the initial commit containing all the code with licence headers? Or maybe is there some advanced Git functionality that allows me to apply the licence header to all existing commits some how? Cheers.

• How to advocate Stack Overflow at work

  - by Gordon

  I am thinking of doing a short presentation at work about using Stack Overflow as a resource for your day job. What is the experience doing this? Would you deem it a valid resource to tell you colleagues about or is it similar to telling them about Google as a resource? Is there a better way of doing it? I was leaning toward asking questions side of Stack Overflow rather than answering them to avoid you-shouldn't-be-doing-this-on-work-time argument. Just as a follow up. Originally I didn't want to make the question to specific to my own case. My presentation will only be a quick four minute talk, which I will repeat over an hour to different groups. I may ask a question before the talk on Stack Overflow and refer to it during the presentation. Hopefully I will get some activity during the hour. I am also going to talk briefly about some of the other Stack Exchange sites that would fit the audience as they are not all developers. I think Super User, Server Fault and Programmers should work well. I will not be doing the presentation for another couple of months as it has be rescheduled, but I will update on how I got on.

• Python web frameworks comparisons

  - by stupidLearner

  I recently asked a question on SO about Python web frameworks: http://stackoverflow.com/questions/4909306/python-web-frameworks-vs-java-web-frameworks-how-is-web-development-in-python-do I want to learn one just for fun but it also has to be able to help me deliver a proper working application. I am looking for a framework with lots of features, powerful, mature, with large community, good documentation, books etc. I need something that will help me be more productive in developing my app and not waste time figuring out how to do a certain thing in the framework or how to write workaround around the limitations of the framework. I was thinking one of the following: django, zope, turbogears, pylons. Off course the war is raging out there and there are other alternatives but seems Django is at the top... or is it just hype? I am interested in pros and cons of each. What was the best feature you think the framework has? What is the thing it lacks? What could have been done differently. Help me chose one to learn for starters.

• If not gamedev, what do I do !

  - by brainydexter

  Hi, I am a game dev who was working in the game-industry and then..got laid off. Ever since then, life couldn't get less stressful! During this time, I have met so many other devs who have also been laid off irrespective of the number of years they have been in the game. Now, the problem really gets worse, since I am not a US citizen (yes, I am in US) , and am on an international visa here, I might have to soon pack my bags and go back to my native country. Going back is not bad at all, apart from the fact, that gamedev is still in a very nascent stage there. There just aren't many opportunities. So, employment is the key to maintain a valid visa status. After giving it a lot of thought, I am thinking of staying away from gamedev jobs for the time being, given its job unstablity. This brings me to my current problem. I can't think of a domain/place where I can use my game development skills. I know graphics/simulation/visualization is huge, but I can't think straight and am left clueless where to go from here. What are some of the domains/companies where I can use my skills ? I'd appreciate any insight on this (and I apologize if this is not the place to post this kind of a question).

• how do I write a functional specification quickly and efficiently

  - by giddy

  So I just read some fabulous articles by Joel on specs here. (Was written in 2000!!) I read all 4 parts, but Im looking for some methodical approaches to writing my specs. Im the only lonely dev, working on this fairly complicated app (or family of apps) for a very well known finance company. I've never made something this serious, I started out writing something like a bad spec, an overview of some sorts, and it has wasted a LOT of my time. Ive also made 3 mockup-kinda-thingies for my client so I have a good understanding of what they want. Also released a preview (a throw away working app with the most basic workflow), and Ive only written and tested some of the very core/base systems. I think the mistake Ive been making so far is not writing a detailed spec, so Im getting to it now. So the whole thing comprises of An MVC website (for admins & data viewing) 2 Silverlight modules (For 2 specific tasks) 1 Desktop Application Im totally short on time, resources and need to get this done quick, also, need to make sure these guys read it up equally quick and painlessly. So how do I go about it, Im looking for any tips, any real world stuff, how do you guys usually do it? Do you make a mock screenie of every dialog/form/page? Im thinking of making a dummy asp.net web forms project, then filling in html files in folders and making it look like my mvc url structure. Then having a section in the spec for the website and write up a page for every URL Ive got with a screenie. For my win forms app, Ive made somewhat of a demo Win Form project, would I then put in a dialog or stucture everything as I would in the real app and then screen shot it?

• Teaching myself, as a physicist, to become a better programmer

  - by user787267

  I've always liked physics, and I've always liked coding, so when I got the offer for a PhD position doing numerical physics (details are not relevant, it's mostly parallel programming for a cluster) at a university, it was a no-brainer for me. However, as most physicists, I'm self taught. I don't have broad background knowledge about how to code in an object oriented way, or the name of that specific algorithm that optimizes the search in some kD tree. Since all my work so far has been more concerned about the physics and the scientific results, I undoubtedly have some bad habits - more so because my coding is my own, and not really teamwork. I have mostly used C since it is very straightforward and "what you write is what you get" - no need for fancy abstractions. However, I have recently switched to C++ since I'd like to learn more about the power that comes with abstraction, and it's pretty C-like (syntax-wise at least). How do I teach myself to code in a good, abstract way like a graduate in computer science? I know my code is efficient, but I want it to be elegant as well, and readable. Keep in mind that I don't have time to read several 1000-page tomes about abstract programming. I need to spend time on actual, physics related research (my supervisor would laugh at me if he knew I spent time thinking about how to program elegantly). How do I assess if my work is also good from a programmer's perspective?

• How to build MVC Views that work with polymorphic domain model design?

  - by Johann de Swardt

  This is more of a "how would you do it" type of question. The application I'm working on is an ASP.NET MVC4 app using Razor syntax. I've got a nice domain model which has a few polymorphic classes, awesome to work with in the code, but I have a few questions regarding the MVC front-end. Views are easy to build for normal classes, but when it comes to the polymorphic ones I'm stuck on deciding how to implement them. The one (ugly) option is to build a page which handles the base type (eg. IContract) and has a bunch of if statements to check if we passed in a IServiceContract or ISupplyContract instance. Not pretty and very nasty to maintain. The other option is to build a view for each of these IContract child classes, breaking DRY principles completely. Don't like doing this for obvious reasons. Another option (also not great) is to split the view into chunks with partials and build partial views for each of the child types that are loaded into the main view for the base type, then deciding to show or hide the partial in a single if statement in the partial. Also messy. I've also been thinking about building a master page with sections for the fields that only occur in subclasses and to build views for each subclass referencing the master page. This looks like the least problematic solution? It will allow for fairly simple maintenance and it doesn't involve code duplication. What are your thoughts? Am I missing something obvious that will make our lives easier? Suggestions?

• How can I support objects larger than a single tile in a 2D tile engine?

  - by Yheeky

  I´m currently working on a 2D Engine containing an isometric tile map. It´s running quite well but I'm not sure if I´ve chosen the best approach for that kind of engine. To give you an idea what I´m thinking about right now, let's have a look at a basic object for a tile map and its objects: public class TileMap { public List<MapRow> Rows = new List<MapRow>(); public int MapWidth = 50; public int MapHeight = 50; } public class MapRow { public List<MapCell> Columns = new List<MapCell>(); } public class MapCell { public int TileID { get; set; } } Having those objects it's just possible to assign a tile to a single MapCell. What I want my engine to support is like having groups of MapCells since I would like to add objects to my tile map (e.g. a house with a size of 2x2 tiles). How should I do that? Should I edit my MapCell object that it may has a reference to other related tiles and how can I find an object while clicking on single MapCells? Or should I do another approach using a global container with all objects in it?

• Inevitable Corporate Bureaucracy

  - by Ahsan Alam

  Top executives of most smaller organizations want their companies to be different from the larger corporations. They want their organizations smaller in size; but bigger in productivity by eliminating red tapes and corporate bureaucracy. When the company is smaller, people often work like firefighters – taking on new business and technology challenges without thinking about any procedures and guidelines. People also tend to wear many hats to accomplish tasks quickly in order to integrate new businesses. For example, software developers in smaller organizations may take on responsibilities of client interactions, requirements gathering, design and development, code deployment, production support, network infrastructure support, database design and maintenance along with countless other duties. In addition, systems in smaller organizations tend to be loosely guarded. So, people often don't follow many procedures in order to setup environments and implement technical projects. It's not uncommon to change code and deploy without anyone realizing. Similarly, business requirements may also get defined in an informal manner without any type of documentation. As the company grows, everything starts to change significantly impacting people and the overall business process. Suddenly, following procedures become extremely important. Consequently, new roles, guidelines and procedures start to emerge. Everything from business process to technology implementation start to become more and more process oriented. Organizations start to define and document steps, invent procedure to track process and systems level changes, and start restricting access to various systems for security reasons. At the same time, as a growing company start doing businesses with larger clienteles, they are automatically forced to abide by all sorts of industry compliance laws. Moreover, growing companies tend to recruit experienced individuals to fill new roles who usually bring their expertise from larger and more bureaucratic organizations.   Despite the best efforts from the top executives, it seems increased number of procedures and guidelines as well as new recruits automatically contribute to the evolution of corporate bureaucracy. Maybe, corporate bureaucracy is an inevitable side effect of a growing organization.

• Writing cross-platforms Types, Interfaces and Classes/Methods in C++

  - by user827992

  I'm looking for the best solution to write cross-platform software, aka code that I write and that I have to interface with different libraries and platforms each time. What I consider the easiest part, correct me if I'm wrong, is the definition of new types, all I have to do is to write an hpp file with a list of typedefs, I can keep the same names for each new type across the different platforms so my codebase can be shared without any problem. typedefs also helps me to redefine a better scope for my types in my code. I will probably end up having something like this: include |-windows | |-types.hpp |-linux | |-types.hpp |-mac |-types.hpp For the interfaces I'm thinking about the same solution used for the types, a series of hpp files, probably I will write all the interfaces only once since they rely on the types and all "cross-platform portability" is ensured by the work done on the types. include | |-interfaces.hpp | |-windows | |-types.hpp |-linux | |-types.hpp |-mac | |-types.hpp For classes and methods I do not have a real answer, I would like to avoid 2 things: the explicit use of pointers the use of templates I want to avoid the use of the pointers because they can make the code less readable for someone and I want to avoid templates just because if I write them, I can't separate the interface from the definition. What is the best option to hide the use of the pointers? I would also like some words about macros and how to implement some OS-specifics calls and definitions.

• Tell me what&rsquo;s wrong! &ndash; An XNA sample demonstrating exception handling and reporting in

  - by George Clingerman

  I’ve always enjoyed using Nick Gravelyn’s exception handling in all of my games. You’re always going to encounter those unhandled exception that your players are going to ferret out and having a method to display them rather than just crashing to the dashboard is definitely more of an elegant solution. But the other day I got to thinking…what if we could do more? What if instead of just displaying the error, we could encourage the players to send us the error. So I started playing with that an expanding upon Nick’s sample code to see what I could come up with. I got close to what I envisioned, but unfortunately there were some limitations to just what the XNA API could do. In my head I was picturing the players hitting “Send Message” and a 360 message would just be sent to the XBLIG developer. Unfortunately, you can only send messages in an XNA game to someone you’re currently in a network session with. Since I didn’t want to have a 360 server running all the time, virally connecting to players just to get error messages, I did the next best thing and just open up a 360 message and encourage them to manually enter the gamertag. Maybe someday we’ll be able to do that a little better, but this works for now. In the sample, players can hit the “A” button or key to generate in an exception. If the debugger is not attached, then the Exception message screen will be shown explaining what has happened and giving the player a chance to send a 360 message to the gamertag provided or maybe even just send an email. Nick’s code has been changed just a bit. It now accepts any PlayerIndex (no longer hard coded to just PlayerIndex.One) and it no longer uses a MessageBox to get the users selection. The code has also been modified so that it works both for the 360 and for the PC. Check out “Tell me what’s wrong!” and let me know if you have any thoughts or suggestions. I really do appreciate the feedback.

• SEO for Country & Language Specific content.

  - by kecebongsoft

  Currently I am creating a website which has a common topic for an article, but it's going to be different content for each country, and also, each of that content will be provided in several languages. And this mechanism exists in most of the parts in the website. For example, I have an article about tax. This article has to be different for each country, for example china. And tax content for china should be written in china AND english language (for non china-speaker). What is the best URL pattern to handle this? What I've been thinking is, using a sub folder (/country-code/language-code/) such as: www.example.com/cn/cn/tax www.example.com/cn/en/tax Or using top level domain such as: www.example.cn/cn/tax www.example.cn/en/tax Or subdomain such as cn.example.com/cn/tax cn.example.com/en/tax I think I will not prefer the last option since I might need to use subdomain for other purpose. Which left only subfolder and TLDN. I've read some articles saying that TLDN is good for localized content (language-specific content), but in my case, my TLDN will also has english contents (for non local speaker) which is specific only to that particular country (also the purpose of this is to let people from other country easily search it through google). What is the best pattern to pick and why?.

• Getting into driver development for linux [closed]

  - by user1103966

  Right now, I've been learning about writing device-drivers for linux 3.2 kernel for about 2 months. So far I have been able program simple char drivers that only read and write to a fictitious dev structure like a file, but now I'm moving to more advance concepts. The new material I've learned about includes I/O port manipulation, memory management, and interrupts. I feel that I have a basic understanding of overall driver operation but, there is still so much that I don't know. My question is this, given that I have the basic theory of how to write a dev-driver for a piece of hardware ... how long would it take to actually develop the skills of writing actual software that companies would want to employ? I plan on getting involved in an open-source project and building a portfolio. Also what type of beginner drivers could I write for hardware that would best help me develop my skills? I was thinking that taking on a project where I design my own key logger would easy and a good assignment to help me understand how IO ports and interrupts are used. I may want to eventually specialize in writing software for video cards or network devices though these devices seem beyond my understanding at the moment. Thanks for any help

• What are my options for sharing music between Windows & Ubuntu on the same network?

  - by jgbelacqua

  We have a few Windows(XP & 7) and Ubuntu machines in the house sharing a wireless connection, and want to share music between them. If possible, I would like to be able to serve music from both Windows and Ubuntu (but it doesn't have to be the same time). I don't know much about sharing folders or streaming, but I'm guessing both would be options (that is, using a local client to access a shared song or a local client to access a shared stream). I want to be able to share the music between the systems as simply as possible. Bonus points (but not requirements) for cross-platform -- same application on both Windows and Ubuntu? available on startup (via daemon or autostart or whatnot) open source More info: All systems have dynamic addresses (DHCP) supplied from the ISP-supplied wireless router. There are several Gigabytes of music on one Windows XP box and one Ubuntu 10.10 The music is not well-sorted (I'm thinking this might have an impact on UI usability). Only has to be available internally (private address space behind the wireless router) bandwidth is not a problem We don't have (legitimate) admin access to the wireless router

• XNA Required information to represent 2D Sprite graphically

  - by Fire-Dragon-DoL

  I was thinking about dividing my game engine into 2 threads: render thread and update thread (I can't come up on how to divide update thread from physic thread at the moment). That said, I have to duplicate all Sprite informations, what do I really need to represents a 2D Sprite graphically? Here are my ideas (I'll mark with ? things that I'm not sure): Vector2 Position float Rotation ? Vector2 Pivot ? Rectangle TextureRectangle Texture2D Texture Vector2 ImageOrigin ? (is it tracked somewhere else?) If you have any suggestion about using different types for datas, it's appreciated Last part of the question: isn't this a lot of data to copy in a buffer?what should I really copy in the buffer?I'm following this tutorial: http://www.sgtconker.com/2009/11/article-multi-threading-your-xna/3/ Thanks UPDATE 1: Newer values at the moment: Vector2 Position float Rotation Vector2 Pivot Rectangle TextureRectangle Texture2D Texture Color Color byte Facing (can be left or right, I'll do it with an enum) I re-read the tutorial, what I was doing wrong is not that I need to pass all those values, I need to pass only changed values as messages. UPDATE 2: Vector2 Position float Rotation Vector2 Pivot Rectangle TextureRectangle Texture2D Texture Color Color bool Flip uint DrawOrder Vector2 Scale bool Visible ? Mhhh, should Visibile be included?

• Entity Framework with large systems - how to divide models?

  - by jkohlhepp

  I'm working with a SQL Server database with 1000+ tables, another few hundred views, and several thousand stored procedures. We are looking to start using Entity Framework for our newer projects, and we are working on our strategy for doing so. The thing I'm hung up on is how best to split the tables into different models (EDMX or DbContext if we go code first). I can think of a few strategies right off the bat: Split by schema We have our tables split across probably a dozen schemas. We could do one model per schema. This isn't perfect, though, because dbo still ends up being very large, with 500+ tables / views. Another problem is that certain units of work will end up having to do transactions that span multiple models, which adds to complexity, although I assume EF makes this fairly straightforward. Split by intent Instead of worrying about schemas, split the models by intent. So we'll have different models for each application, or project, or module, or screen, depending on how granular we want to get. The problem I see with this is that there are certain tables that inevitably have to be used in every case, such as User or AuditHistory. Do we add those to every model (violates DRY I think), or are those in a separate model that is used by every project? Don't split at all - one giant model This is obviously simple from a development perspective but from my research and my intuition this seems like it could perform terribly, both at design time, compile time, and possibly run time. What is the best practice for using EF against such a large database? Specifically what strategies do people use in designing models against this volume of DB objects? Are there options that I'm not thinking of that work better than what I have above? Also, is this a problem in other ORMs such as NHibernate? If so have they come up with any better solutions than EF?

• Sharing authentication methods across API and web app

  - by Snixtor

  I'm wanting to share an authentication implementation across a web application, and web API. The web application will be ASP.NET (mostly MVC 4), the API will be mostly ASP.NET WEB API, though I anticipate it will also have a few custom modules or handlers. I want to: Share as much authentication implementation between the app and API as possible. Have the web application behave like forms authentication (attractive log-in page, logout option, redirect to / from login page when a request requires authentication / authorisation). Have API callers use something closer to standard HTTP (401 - Unauthorized, not 302 - Redirect). Provide client and server side logout mechanisms that don't require a change of password (so HTTP basic is out, since clients typically cache their credentials). The way I'm thinking of implementing this is using plain old ASP.NET forms authentication for the web application, and pushing another module into the stack (much like MADAM - Mixed Authentication Disposition ASP.NET Module). This module will look for some HTTP header (implementation specific) which indicates "caller is API". If the header "caller is API" is set, then the service will respond differently than standard ASP.NET forms authentication, it will: 401 instead of 302 on a request lacking authentication. Look for username + pass in a custom "Login" HTTP header, and return a FormsAuthentication ticket in a custom "FormsAuth" header. Look for FormsAuthentication ticket in a custom "FormsAuth" header. My question(s) are: Is there a framework for ASP.NET that already covers this scenario? Are there any glaring holes in this proposed implementation? My primary fear is a security risk that I can't see, but I'm similarly concerned that there may be something about such an implementation that will make it overly restrictive or clumsy to work with.

• Coding Dynamic Events?

  - by Joey Green

  I have no idea what the title of this question should be so bare with me. My game has turns. On a turn a player does something and this can result in a random number of explosions that occur at different times. I know when the explosions are done. I need to know when ALL are done and then do some other action. Also, each explosion is the same amount of time, say 3 seconds.. Right now I'm thinking of using a counter to hold how many explosions are happening. Then once the explosion is finished decrement this counter. Once the counter is zero, do my action. This idea is inspired by objective-c memory management btw. Anyways, does this sound like a good approach or would there be another way. An alternative might be to figure out the explosion who happened last and let it be responsible for calling this subsequent action. I'm asking mostly, because I haven't done this before and am trying to figure out if there are bugs that may occur that I'm not foreseeing.

  I would like to implement entity system in my game and I've got some question about entity system and rendering. Currently, my renderer got two types of elements: Current design Mesh : A default renderable with a Material, a Geometry and a Transformable Sprite : A type of mesh with some methods like "flip" and "setRect" methods and a rect member (With an imposed geometry, a quad) This objects inherit from "Spacial" class. Questions: How can I handle this two types in an entity system? I'm thinking about using "MeshComponent" and "SpriteComponent", but if I do that, an entity could have a Mesh and a Sprite at the same type, it's look stupid, right? I thought the idea to have a parent "rendering" component : "RenderableComponent" for "MeshComponent" and "SpriteComponent" but it will be difficult to handle "cast" in the game (ex: did I need to ask entity-getComponent or SpineComponent, …) Thanks a lot for reading me! My entity system work like that: --------------------------------------------------------------------------- Entity* entity = world->createEntity(); MeshComponent* mesh = entity->addComponent<MeshComponent>(material); mesh->loadFromFile("monkey.obj"); PhysicComponent* physic = entity->addComponent<PhysicComponent>(); physic->setMass(5.4f); physic->setVelocity( 0.5f, 2.f ); --------------------------------------------------------------------------- class RenderingSystem { private: Scene scene; public: void onEntityAdded( Entity* entity ) { scene.addMesh( entity->getComponent<MeshComponent>() ); } } class PhysicSystem { private: World world; public: void onEntityAdded( Entity* entity ) { world.addBody( entity->getComponent<PhysicComponent>()->getBody() ); } void process( Entity* entity ) { PhysicComponent* physic = entity->getComponent<PhysicComponent>(); } } ---------------------------------------------------------------------------

• Distinction between API and frontend-backend

  - by Jason

  I'm trying to write a "standard" business web site. By "standard", I mean this site runs the usual HTML5, CSS and Javascript for the front-end, a back-end (to process stuff), and runs MySQL for the database. It's a basic CRUD site: the front-end just makes pretty whatever the database has in store; the backend writes to the database whatever the user enters and does some processing. Just like most sites out there. In creating my Github repositories to begin coding, I've realized I don't understand the distinction between the front-end back-end, and the API. Another way of phrasing my question is: where does the API come into this picture? I'm going to list some more details and then questions I have - hopefully this gives you guys a better idea of what my actual question is, because I'm so confused that I don't know the specific question to ask. Some more details: I'd like to try the Model-View-Controller pattern. I don't know if this changes the question/answer. The API will be RESTful I'd like my back-end to use my own API instead of allowing the back-end to cheat and call special queries. I think this style is more consistent. My questions: Does the front-end call the back-end which calls the API? Or does the front-end just call the API instead of calling the back-end? Does the back-end just execute an API and the API returns control to the back-end (where the back-end acts as the ultimate controller, delegating tasks)? Long and detailed answers explaining the role of the API alongside the front-end back-end are encouraged. If the answer depends on the model of programming (models other than the Model-View-Controller pattern), please describe these other ways of thinking of the API. Thanks. I'm very confused.

• Representing and executing simple rules - framework or custom?

  - by qtips

  I am creating a system where users will be able to subscribe to events, and get notified when the event has occured. Example of events can be phone call durations and costs, phone data traffic notations, and even stock rate changes. Example of events: customer 13532 completed a call with duration 11:45 min and cost $0.4 stock rate for Google decreased with 0.01% Customers can subscribe to events using some simple rules e.g. When stock rate of Google decreases more than 0.5% When the cost of a call of my subscription is over $1 Now, as the set of different rules is currently predefined, I can easily create a custom implemention that applies rules to an event. But if the set of rules could be much larger, and if we also allow for custom rules (e.g. when stock rate of Google decreses more than 0.5% AND stock rate of Apple increases with 0.5%), the system should be able to adapt. I am therefore thinking of a system that can interpret rules using a simple grammer and then apply them. After som research I found that there exists rule-based engines that can be used, but I am unsure as they seem too complicated and may be a little overkill for my situation. Is there a Java framework suited for this area? Should we use framework, a rule engine, or should we create something custom? What are the pros and cons?
