• Is there an open source license that allows any use, except within a GPL/copyleft project? [on hold]

  - by Marcos Scriven

  I would like to open source some code with a permissive license (say MIT/BSD) I would be happy for it to be used both commercially and in any open source project that is not copyleft (GPL being the main one obviously). I looked at the list of non-GPL compatible licenses here: http://www.gnu.org/licenses/license-list.html#GPLIncompatibleLicenses But none seemed to be quite what I wanted. Is there such a license already? If not, would it even be possible to do this? EDIT: I have been asked to edit this question to clarify. I'm not sure how it's unclear, as that wasn't stated. What I would like to know is simply the answer to the topic - can anyone point to a standard licence that is permissive as possible, while restricting use in copyleft licence. I'm not clear why the question would be suspended by the same person that edited spelling differences (apparently British English is a 'mistake') in the question earlier, and by another that had answered licencing questions in other posts.

• How can I bind a custom color to WPF toolkit ColorPicker? [on hold]

  - by tube-builder

  I need to bind the SelectedColor property of ColorPicker to a custom color which is not present in available colors. I created a simple test to show my problem. My xaml: <xctk:ColorPicker SelectedColor="{Binding Path=Test}"></xctk:ColorPicker> Code behind (CurrentStyle.PenColor returns an integer value which equals 13109765): public Color Test { get; set; } public MyClass() { DataContext = this; Test = Color.FromArgb((byte)((CurrentStyle.PenColor >> 24) & 0xFF), (byte)((CurrentStyle.PenColor >> 16) & 0xFF), (byte)((CurrentStyle.PenColor >> 8) & 0xFF), (byte)(CurrentStyle.PenColor & 0xFF)); InitializeComponent(); } And that's how my ColorPicker looks like when the window is loaded (I don't have enough rep to post images so it's just links): http://s22.postimg.org/frzh2fgy9/image.png Though, when I go to Advanced colors I can see that the color has been recognized and set correctly. Here is a pic: http://s13.postimg.org/gjv4cmy07/image.png Hope for your help. Thanks a lot! EDIT I implemented INotifyPropertyChanged, still to no avail. Here's the code: public Color Test { get { return test; } set { if (test != value) { test = value; OnPropertyChanged("Test"); } } } public event PropertyChangedEventHandler PropertyChanged; protected void OnPropertyChanged(string prop) { if (this.PropertyChanged != null) this.PropertyChanged(this, new PropertyChangedEventArgs(prop)); } Maybe I'm doing smth wrong here.

• Will Swift or any upcoming Apple developer tools be incompatible with .xibs? [on hold]

  - by user

  I'm still letting the sudden announcement of a language change (Swift) sink in, and I'm wondering if the upcoming platform changes will still be highly compatible with using .xibs for interface development. I've used Storyboards in multiple production projects but I don't feel very productive with them, and I get tired of managing multiple storyboards, links, and xib connections for complex views. I don't see why Swift and Xcode 6 wouldn't cooperate with Xibs indefinitely if it still allows @IBOutlets and @IBActions, but I have realized that Apple purposely shuns old methodologies for the sake of doing so. If there's any reasons to turn away from xibs in iOS8 besides the use-the-new-stuff conventional wisdom, I'd like to know before its too late.

• Which Game Engine to Use for an Angry Bird style game? [JAVA] [on hold]

  - by Arch1tect

  Our team is building an Angry Bird Style game, and we have only about ten days. The game is a little more complex than Angry Bird because there are two players, they each have a castle with pigs to protect(not destroy:)). And the goal is to destroy the other player's pigs. I wonder what Game Engine would help us finish this game most efficiently. We at least need a physics engine but I guess game engine is more helpful since it usually includes physics engine. Correct me if I'm wrong. (So I'm wondering which game engine I should use, if it's just physics engine, I'll use box2d) Networking may or may not be added later depend on time we have. Thanks in advance for any advice! EDIT: image looks small, I'll add one:

• Breadcrumbs in a modern web application, make sense? [on hold]

  - by Xtreme Biker

  I'm currently beginning with the development of a new web application. The whole web application is going to be bookmarkable and all the pages accesible via GET requests and url parameters. Having said that, let's suppose I've got three entities in my application, Customer, Team and City. Each Customer and Team belong to a city and I've got a city-detail page which displays the detail for a concrete city. So next navigation cases are possible: Customers - Customer detail (id=2) - City detail (id=3) Football teams - Team detail (id=5) - City detail (id=3) Cities - City detail (id=3) There are three possible ways of ending up in a city detail view. My question is, does it make sense to implement a breadcrumb to show such a history, having it available in the browser itself? Would it be more appropiate to show a breadcrumb with the last case, no matter where we're coming from (hierarchical breadcrumb)? That's what Jakob Nielsen points out here: Offering users a Hansel-and-Gretel-style history trail is basically useless, because it simply duplicates functionality offered by the Back button, which is the Web’s second-most-used feature. A history trail can also be confusing: users often wander in circles or go to the wrong site sections. Having each point in a confused progression at the top of the current page doesn’t offer much help. Finally, a history trail is useless for users who arrive directly at a page deep within the site. Also, even if the history trail seems the most natural way to implement it, it requires an extra effort to keep the whole track being HTTP a stateless mean.

• should I learn html/css before php even for using database? [on hold]

  - by Sadegh

  I saw lots of question about this topic and all of them were talking if someone want to use php for "building web pages", should learn html first or not. and most of them said yes, because most of the time you make web page with both php and html (and maybe css). But If I just want to use php for contacting to My Database (for example MySQL) and nothing more, shuold I learn any html or CSS first or not?

• What good books are out there on program execution models? [on hold]

  - by murungu

  Can anyone out there name a few books that address the topic of program execution models?? I want a book that can answer questions such as... What is the difference between interpreted and compiled languages and what are the performance consequences at runtime?? What is the difference between lazy evaluation, eager evaluation and short circuit evaluation?? Why would one choose to use one evaluation strategy over another?? How do you simulate lazy evaluation in a language that favours eager evaluation??

• What is a better language to use when building a database: Visual C# or Visual Basic (VB.net)? [on hold]

  - by user3413537

  I'm building a GUI and a database which is using SQL as a server (internal database not a web application). Which language is more of a "right tool" when it comes to building a not very structurally complicated database? What are the advantages and disadvantages of Visual C# / VB.net? I've been reading a lot of stuff online and they said that VB.net is not as capable and it doesn't have as much support as Visual C#, and it seems that VB.net is on a decline in terms of popularity.

• how to retrieve img alt text with jquery or javascript? [on hold]

  - by kate

  Which is the code with which we can retreive alternative text of image: It is a Cataloge with clothes. Dressers, Shirts, Skirts e.t.c. in front page of a site. The featured images of the categories can be changed manually from someone. I did a check and it is asking me to give alt text. I did it to some images with alt="". But to the cataloge I cannot do it. the code is below: {{ 'option_selection.js' | shopify_asset_url | script_tag }} {{ 'api.jquery.js' | shopify_asset_url | script_tag }} {% if template contains 'customers' %} {{ 'shopify_common.js' | shopify_asset_url | script_tag }} {{ 'customer_area.js' | shopify_asset_url | script_tag }} {% endif %} {% if settings.display_slideshow %}{{ 'jquery.slider.js' | asset_url | script_tag }}{% endif %} {% if settings.include_masonry %}{{ 'jquery.masonry.js' | asset_url | script_tag }}{% endif %} {% if settings.enable_product_image_zoom %}{{ 'jquery.zoom.js' | asset_url | script_tag }}{% endif %} {{ 'fancy.js' | asset_url | script_tag }} {{ 'shop.js' | asset_url | script_tag }} Shopify.money_format = '{{ shop.money_format }}'; {% if template contains "product" %} jQuery(document).ready(function($){ {% if product.variants.size 1 or product.options.size 1 %} new Shopify.OptionSelectors("product-select", { product: {{ product | json }}, onVariantSelected: selectCallback }); {% assign found_one_in_stock = false %} {% for variant in product.variants %} {% if variant.available and found_one_in_stock == false %} {% assign found_one_in_stock = true %} {% for option in product.options %} $('#product-select-option-' + {{ forloop.index0 }}).val({{ variant.options[forloop.index0] | json }}).trigger('change'); {% endfor %} {% endif %} {% endfor %} {% endif %} }); $(function() { $( "#tabs" ).tabs(); });

  I have bean an artist for many years now I am very comfortable with using Photoshop and Flash but I want to learn how to but together my own games, I bean doing my own research into this and at the moment I am at little bit stuck on witch direction to go down. So my question is witch programming language should I learn? I have already bean looking into this what i understand is that Gamemaker with its built in language (GML) is one of the most friendly to people who are new to the game making world. I have played around with this program and was pretty happy with it but I want more also you can use Unity with language such as C and javascript and then games built with Java witch looks interesting. One more thing before you send your answer in at this moment in time I would only be able to make 2D game but 3D isn't out of the picture.

• Are there any good html 5 mmo design tutorials? [on hold]

  - by Dwight Spencer

  Hey all. I got a rather inspired after playing gaia online's zOMG and wanted to revive an old project idea I've had laying around for a few years now. I'm looking to work with html5 (ie canvas, svg based sprites, & WebGL) to build a graphical web based MUD/MMO. Obviously, this is a new take on an old idea and after searching google I haven't really turned up many good resources. But does anyone have any tutorials or other resources to point me in the right direction?

• How can I solve the same problems a CB-architecture is trying to solve without using hacks? [on hold]

  - by Jefffrey

  A component based system's goal is to solve the problems that derives from inheritance: for example the fact that some parts of the code (that are called components) are reused by very different classes that, hypothetically, would lie in a very different branch of the inheritance tree. That's a very nice concept, but I've found out that CBS is often hard to accomplish without using ugly hacks. Implementations of this system are often far from clean. But I don't want to discuss this any further. My question is: how can I solve the same problems a CBS try to solve with a very clean interface? (possibly with examples, there are a lot of abstract talks about the "perfect" design already). Here's an example I was going for before realizing I was just reinventing inheritance again: class Human { public: Position position; Movement movement; Sprite sprite; // other human specific components }; class Zombie { Position position; Movement movement; Sprite sprite; // other zombie specific components }; After writing that I realized I needed an interface, otherwise I would have needed N containers for N different types of objects (or to use boost::variant to gather them all together). So I've thought of polymorphism (move what systems do in a CBS design into class specific functions): class Entity { public: virtual void on_event(Event) {} // not pure virtual on purpose virtual void on_update(World) {} virtual void on_draw(Window) {} }; class Human { private: Position position; Movement movement; Sprite sprite; public: virtual void on_event(Event) { ... } virtual void on_update(World) { ... } virtual void on_draw(Window) { ... } }; class Zombie { private: Position position; Movement movement; Sprite sprite; public: virtual void on_event(Event) { ... } virtual void on_update(World) { ... } virtual void on_draw(Window) { ... } }; Which was nice, except for the fact that now the outside world would not even be able to know where a Human is positioned (it does not have access to its position member). That would be useful to track the player position for collision detection or if on_update the Zombie would want to track down its nearest human to move towards him. So I added const Position& get_position() const; to both the Zombie and Human classes. And then I realized that both functionality were shared, so it should have gone to the common base class: Entity. Do you notice anything? Yes, with that methodology I would have a god Entity class full of common functionality (which is the thing I was trying to avoid in the first place).

• Interactive Fiction engine and Tech Support - has anyone done this? [on hold]

  - by Larry G. Wapnitsky

  I've always been a big fan of Interactive Fiction and have been wanting to try my hand at it for a while. I have a need to create a decision tree for my tech support group (L1-L3) and feel as though presenting a decision tree in the form of an IF game would be rather interesting and helpful. I plan on using Inform7, but am curious if anyone has done anything like this in the past. If so, can you present examples, links to examples, opinions? Thanks, Larry

• In an Entity/Component system, can component data be implemented as a simple array of key-value pairs? [on hold]

  - by 010110110101

  I'm trying to wrap my head around how to organize components in an Entity Component Systems once everything in the current scene/level is loaded in memory. (I'm a hobbyist BTW) Some people seem to implement the Entity as an object that contains a list of of "Component" objects. Components contain data organized as an array of key-value pairs. Where the value is serialized "somehow". (pseudocode is loosely in C# for brevity) class Entity { Guid _id; List<Component> _components; } class Component { List<ComponentAttributeValue> _attributes; } class ComponentAttributeValue { string AttributeName; object AttributeValue; } Others describe Components as an in-memory "table". An entity acquires the component by having its key placed in a table. The attributes of the component-entity instance are like the columns in a table class Renderable_Component { List<RenderableComponentAttributeValue> _entities; } class RenderableComponentAttributeValue { Guid entityId; matrix4 transformation; // other stuff for rendering // everything is strongly typed } Others describe this actually as a table. (and such tables sound like an EAV database schema BTW) (and the value is serialized "somehow") Render_Component_Table ---------------- Entity Id Attribute Name Attribute Value and when brought into running code: class Entity { Guid _id; Dictionary<string, object> _attributes; } My specific question is: Given various components, (Renderable, Positionable, Explodeable, Hideable, etc) and given that each component has an attribute with a particular name, (TRANSLATION_MATRIX, PARTICLE_EMISSION_VELOCITY, CAN_HIDE, FAVORITE_COLOR, etc) should: an entity contain a list of components where each component, in turn, has their own array of named attributes with values serialized somehow or should components exist as in-memory tables of entity references and associated with each "row" there are "columns" representing the attribute with values that are specific to each entity instance and are strongly typed or all attributes be stored in an entity as a singular array of named attributes with values serialized somehow (could have name collisions) or something else???

• Need help with cybersquatting complaint: can a domain name forward AND resolve at same time? [on hold]

  - by Alan

  Probably a silly question for you pros... but for this novice here, I just want to make sure my understanding is correct. Context: I am trying to prove that a domain name owner has been cybersquatting and has never used the domain name in question. There are 4 shots from WayBackMachine over a three-year period that show the domain name resolving to a basic server index page with either no files or a single cgi-bin folder. The domain name owner claims, however, that the domain name was forwarded over the entire time from to another website, and that these captures probably coincided with occasional "outages." It is my understanding that: a) domain name forwarding is binary: if a domain name is forwarded to a valid site, it cannot simultaneously resolve to a valid IP address. Is this correct? b) domain name forwarding is not subject to "outages": servers can have outages, and websites can be down, but the forwarding itself cannot be down, as this is simply a pointer. (Or, the entire registrar where the DNS settings are hosted would have to malfunction. Is this correct? FINALLY, bonus question for pro webmasters: What is the likelihood that the WayBackMachine would capture the domain name on just those occasions when the webmaster disabled forwarding to supposedly work on the new site? Mucho thanks in advance!

• Reason why a Brand new website is ranking for a top keyword? [on hold]

  - by Prasad EBK

  Its been noticed, one of our (new)competitor website is ranking 5 for a top keyword with high competition. The website is barely 2 months old. When I checked not much SEO is done on the website other than basic title/desc tags. No backlinks. The website pushed down our website and took its place for the keyword. The only reason that came to my mind is the latest penguin update. Or is the ranking just temporary???, will it eventually be pushed back?? its been holding on for atleast one month and its irritating. Thanks in advance.

• How to do Cross Platform in own Engine? [on hold]

  - by Mineorbit

  At the Moment I finished the first game with my game engine(if I wanna call it like that) which is based in LWJGL. Now i'm worring if I could do crossplattforming in my engine. I build me a tool tool with a batch file to compile my project dir into an .exe . At first i'm looking to do it on Android with an comparable batch file. An link for an tutorial would be awesome! At next place there would be an renderer and audiosystem. If read that theres an OpenGL ES renderer, and I allready played a bit around with the Android SDK. But I use the Texture and Audio class in slick-util. So I thought about creating OOP classes that carry around the data and load it in an platform specific Buffer. A Link for an equaly easy-to-use Texture or Audio class would be awesome! Thats all for now! Answers would be awesome! Thanks, Mineorbit!

• .NET Compiler Platform (Roslyn) , its relevance to developer community and its performance? [on hold]

  - by jerriclynsjohn

  I'm just starting out with a Code-Quality-plugin development for my organization based on the recently released .NET Compiler Platform APIs (Roslyn APIs). I would like to know what are the most relevant possible ways that it could be used by the developer community apart from the usual IDE experience as answered in other questions. I was wondering the implications of opening up a compiler to general public and never came across anything "breakthrough", that could possibly add up to the value of IDE experiences. Is there any performance bottleneck for its implementation since the compiler itself is managed code?

• I want to be a programmer, work in corporate environment, earn well, learn fast and eventually become a great programmer [on hold]

  - by Shin San

  I'll try to keep this simple: I'm 29, been dabbling with computers for the past 10 years, had entry level jobs in tech support for different apps, been fixing computers for a while and now want to specialize in something. I'm not 100% stranger to programming but haven't gone past if/then/else with anything. A bit of JavaScript, PHP, Python and currently checking out the "SELECT" statement in SQL :)) I'm curious about programming, I enjoy it and I'm thinking of making a living out of it. So, while I'm at it, why not earn a bit more than the average Joe? So, that's why I'm checking what the best solution, the best learning path and the most useful languages are considering: a) how easy/fast can you find a job by knowing it b) how much would I be able to earn c) how fast can I learn it By reading 10-20 articles online I've come up with an example, but I'm here for some expert advice. Example: * ratings from a) and b) point of view #1 sql ; #2 java ; #3 html (please don't start the markup language debate) ; #4 javascript From this ratings, I'd say a good way to go is learn html/css/(javascript or php) for the web part of apps, some SQL/MySQL/whateverSQL for holding data and loads of Java for the program itself. Please let me know if this is a good idea and if so, what should be the order for learning all of the above. Else, please let me know a better way and why it would be better. Many thanks for taking the time to read my question. Best wishes to you guys Edit: if I think Java + SQL + HTML&JavaScript is the way to go, does the order I'm learning them in matter? Or can I try to learn them all at once?
