• L'état de compatibilité des navigateurs internet avec HTML5 et CSS3 présenté par un graphique intera

  Mise à jour du 14.05.2010 par Katleen L'état de compatibilité des navigateurs internet avec HTML5 et CSS3 présenté par un graphique interactif Tout est dit, ou presque, dans le titre. Un graphique disponible en ligne, et crée avec CSS3, traque les taux de prise en charge pour chaque nouvelle fonctionnalité HTML/CSS sur les navigateurs. Les différents browsers sont regroupés sous des camaïeux de couleurs. Par exemple, les différentes versions de Firefox se déclinent dans des bleus, Safari dans des jaunes, Chrome en orange, Internet Explorer dans des roses. Le graphique, de forme solaire, présente des rayons dont les couleurs d'arrière plan diffèrent en cas de fonctionnalité CSS3....

• Is there a class or id that will cause an ad to be blocked by most major adblockers?

  - by Moak

  Is there a general class or ID for a html element that a high majority of popular adblockers will block on a website it has no information for. My intention is to have my advertisement blocked, avoiding automatic blocking is easy enough... I was thinking of maybe lending some ids or classes from big advertisment companies that area already being fought off quite actively. right now my html <ul id=partners> <li class=advertisment><a href=# class=sponsor><img class=banner></a></li> </ul> Will this work or is there a more solid approach?

• How would you design an application with many target platforms and devices?

  - by Pierre 303

  I'm in a very beginning of the design phase of an application that will have to run in the following platforms/devices: Desktop: Windows, Linux & Mac Mobile: Android, iPhone/iPad & Windows Phone 7 Web: Silverlight I will use C# on Mono and I want to maximize code re-usability. Except for the desktop (I'll use WinForms/GTK#), my concern is related to many different GUI that I will face. What would be your approach? Obviously, the views will be different, but what about the controllers, data access, utility classes, etc. Is it really acceptable to share everything but the views?

• Java Developers: Is Ant still in the "main stream" for builds? Do we push new developers to learn it?

  - by Sam Goldberg

  We have been slowly replacing batch command files (windows .bat) which were simply jarring up the classes compiled in the developers IDE, with more comprehensive Ant builds (i.e. get from CVS, clean compile, jar, archive, email, etc.) I've spent a lot of time learning (and debugging issues) with Ant, so I'm most comfortable using it for these tasks. But I wonder if Ant is still in as wide usage as it was when I first started learning, or whether "the world has moved on" to something newer (and maybe slicker). (I've started to see more Maven build stuff distributed, which I've never used, for example.) The practical import of this question, is whether I push new developers to learn Ant, or whether they should be learning something else for builds? I'm never too on top of the trends, so it would be great to hear from other Java developers what they think is the best build tool, and what they think new developers should be learning.

• Google Authorship: can I display:none for link to profile?

  - by RubenGeert

  I'd like to have my 'mugshot' in Google's SERPs but I couldn't care less about Google+. I don't really want to link my website to Google+ either. Can I use CSS display:none; on the link leading to my profile and still have authorship, which looks like <a href='https://plus.google.com/111823012258578917399?rel=author' rel='nofollow'>Google</a>? Will the nofollow attribute here spoil things? I don't want to lose 'link juice' on Google+ if I don't have to. Now Google should crawl only the HTML but I'm sure they'll figure out the link is not visible (perhaps it's technically even cloaking. Does anybody have experience with this situation? And do I really have to become (reasonably) active on Google+ in order for authorship to show? This answer suggests I do but I didn't read anything on that in Google's guidelines.

• Structuring game world entities and their rendering objects

  - by keithjgrant

  I'm putting together a simple 2d tile-based game. I'm finding myself spinning circles on some design decisions, and I think I'm in danger of over-engineering. After all, the game is simple enough that I had a working prototype inside of four hours with fewer than ten classes, it just wasn't scalable or flexible enough for a polished game. My question is about how to structure flow of control between game entity objects and their rendering objects. Should each renderer have a reference to their entity or vice-versa? Or both? Should the entity be in control of calling the render() method, or be completely oblivious? I know there are several valid approaches here, but I'm kind of feeling decision paralysis. What are the pros and cons of each approach?

• Terminology For Web Development and General Programming/Software?

  - by Zenph

  EDIT: I should clarify. THe particular terms I listed below I fully understand. I also understand w3schools doesn't have the greatest information. These are just examples. I don't expect everybody to understand what an example is, but I hope the majority do. Does anybody have any resources listing terms related to programming and web development, or care to pitch in? Things like: Runtime Build time Framework Library Normalize I'm primarily a PHP developer so anything about that. I really am looking for general terms and specific terms related to web development, PHP, SQL, CSS, HTML. Appreciate any input. Couple I found: http://www.w3schools.com/site/site_glossary.asp http://docs.roxen.com/pike/7.0/tutorial/fundamentals/concepts.xml

• Is having a class have a handleAction(type) method bad practice?

  - by zhenka

  My web application became a little too complicated to do everything in a controller so I had to build large wrapper classes for ORM models. The possible actions a user can trigger are all similar and after a certain point I realized that the best way to go would be to just have constructor method receive action type as a parameter to take care of the small differences internally, as opposed to either passing many arguments or doing a lot of things in the controller. Is this a good practice? I can't really give details for privacy issues.

• ViewController in programming

  - by Vishwas Gagrani

  ViewController is a term for classes that handle views in a framework. This is especially used in MVC frameworks. I go through various projects, written by various programmers, who implement MVC in different ways. Especially, i get confused, about the relation between the MainView ( parent view ) and some CustomView ( widget etc) in the framework. I personally pass reference of the MainView into the ViewController to be instantiated. All the subviews of ViewController are added to that reference of MainView. Additionally, ViewController itself is added as a child of MainView. Like this : Want to know, if this is the right way to relate each other ?

• MCP 1.7.10 Java class navigation

  - by Elias Benevedes

  So, I'm new to the Minecraft modding community and trying to understand where to start. I've attempted to do it before, but dropped it to the complexity of starting and the lack of a site like this to help (Mind that I'm also semi-new to Java, but have worked extensively in Javascript and Python. I understand how Java is different from the two). I have downloaded MCP 9.08 (Decompiles 1.7.10), and decompiled Minecraft. I'm looking to mod client, so I didn't supply it with a server jar. Everything seemed to work fine in decompile (Only error was it couldn't find the server jar). I can find my files in /mcp908/src/minecraft/net/minecraft. However, if I open up one of the classes in, say, block, I see a bunch of variables starting with p_ and ending with _. Is there any way to make these variables more decipherable, to understand what's going on so I can learn by example? Thank you.

• What does "GPL with classpath exception" mean in practice?

  - by Thilo

  Oracle seems to license all their Java-related open source code under the GPL with a classpath exception. From what I understand, this seems to allow to combine these libraries with your own code into products that do not have to be covered by the GPL. How does this work? What are examples of how I can and cannot use these classes? Why was this new license used as opposed to the LGPL, which seems to allow for pretty much the same things, but is better established and understood? What are the differences to the LGPL?

• XNA 4.0 Refresh AudioEngine, WaveBank and Others Not Found

  - by Peteyslatts

  I'm going through the Learning XNA 4.0 book, and unfortunately I installed XNA 4.0 refresh. All the code up until now has worked, with the exception of me needing to remove the Framework.Net and Framework.Storage. (As a side question, will this be problematic later?) The problem I'm having now is that in my Game1.cs file, I have imported all of the XNA.Framework libraries, and when I try and create instances of any of the following classes, an error pops up saying VisualStudio can't find them: AudiEngine, WaveBank, SoundBank, and Cue. I have googled around for a while, and the only solution I saw was to import Microsoft.Xna.Framework.Xact, but this doesn't seem to exist for me. Any help is much appreciated, Thanks Peter.

• Did You Know: What do you know that isn't so?

  - by Kalen Delaney

  You know what they say… it's not what you don't know that will hurt you, it's what you know that isn't so! In other words, your misconceptions. Or, as Paul Nielson calls them in his SQL Server Bible … MYTHconceptions. Some misconceptions come from misunderstanding of complex information, or from misinterpreting your own results, and assuming we can generalize behavior from one particular situation. Since I teach advanced classes to students with lots of SQL Server experience, I actually see a lot...(read more)

• Easy Server-Side Language

  - by Nizar

  Most of programming languages (Server-side languages for web development) needs a learning curve and requires some time to learn. However, I'm sure there is a difference between them. So, for example you can master the 'X' language in less time than the 'Y' language. I'm a beginner in web development, meaning that I just know HTML and CSS and now want to choose the right tool for building dynamic sites. What I'm looking for is a language that is easy to master in less time than other languages. So, is there a language that can suit my needs? If so, please let me know about what should I learn in it? (for example, which frameworks?, libraries?, IDEs?, databases?, etc). In the end, I don't want to regret my choice of the language and want to learn solid basics in it and in programming in general.

• Python Multiprocessing with Queue vs ZeroMQ IPC

  - by Imraan

  I am busy writing a Python application using ZeroMQ and implementing a variation of the Majordomo pattern as described in the ZGuide. I have a broker as an intermediary between a set of workers and clients. I want to do some extensive logging for every request that comes in, but I do not want the broker to waste time doing that. The broker should pass that logging request to something else. I have thought of two ways :- Create workers that are only for logging and use the ZeroMQ IPC transport Use Multiprocessing with a Queue I am not sure which one is better or faster for that matter. The first option does allow me to use the current worker base classes that I already use for normal workers, but the second option seems quicker to implement. I would like some advice or comments on the above or possibly a different solution.

• How can I link to callback functions in Lua such that the callbacks will be updated when the scripts are reloaded?

  - by Raptormeat

  I'm implementing Lua scripting in my game using LuaBind, and one of the things I'm not clear on is the logistics of reloading the scripts live ingame. Currently, using the LuaBind C++ class luabind::object, I save references to Lua callbacks directly in the classes that use them. Then I can use luabind::call_function using that object in order to call the Lua code from the C++ code. I haven't tested this yet, but my assumption is that if I reload the scripts, then all the functions will be redefined, BUT the references to the OLD functions will still exist in the form of the luabind::object held by the C++ code. I would like to be able to swap out the old for the new without manually having to manage this for every script hook in the game. How best to change this so the process works? My first thought is to not save a reference to the function directly, but maybe save the function name instead, and grab the function by name every time we want to call it. I'm looking for better ideas!

• How many developers do I need to build a website like Freelancer.com in about 3-5 months? [closed]

  - by Sam

  I have been asked to make a list of people that I need to build something similar to freelancer.com. Not exactly same, has a few more features to it too but I can't really get my head around the whole freelancer.com site. I have built a social networking site from scratch which is 70% of Facebook and 20% Google+ in about 5 months with raw PHP, JS, CSS and Ajax. I dont think it will take me more than a month or something to build the whole freelancer.com from scratch. Please suggest anything that should I pay attention to. I am thinking about: 2 php developers 1 mysql engineer 1 network/server engineer 1 graphics artist 1 UI developer Time frame: 20 days Is this a good estimation?

• How can I view localized versions of my site?

  - by Max Vernon

  We are adding internationalization to our site. We are getting the client's IP address from the headers and looking it up against the IP2location database to get the client's country. Several of our clients reported seeing a blank page over the weekend. We'd like to be able to get screenshots or use a browser from many different countries on an ongoing basis for testing code changes. I need to know what the site looks like when accessed from various countries since there are several elements that vary by country. I've used Tor and Vidalia, along with the Tor customized Firefox browser however it appears the CSS is getting mangled. I have also used http://webpagetest.org to check the site, however the screenshot it gives is too small to be really useful. Is there a site or a service I can use to get screenshots or interact with my website from various countries?

• Less is More Redux

  In my short happy life as a developer, Ive run into all kinds of development efforts that include frameworks, libraries, web sites, and much more.The one thing that stands out as an irritant to me is complexity. Specifically, unnecessary complexity. Ive seen developers author entire library assemblies that provide wrapper utility methods consisting of calls to .NET BCL methods that take one line of code methods that could have been called inline without even the need for the helper classes.Ive seen...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Programmers Block ?? [closed]

  - by Robert Ventre

  Possible Duplicate: Is there such a thing as Programmer's block? Has anyone had writers block? Currently, I am trying to get back in to a development role but am struggling to develop any apps. I have a good understanding of VB and OOP. I developed last in the first version of .net studio and also foxpro 9. At the moment I have tried building a customer order app, the form and database have been straight forward but I'm struggling with the nuts and bolts of the application. Should it be a Web or Windows application? Should I use classes/modules? All advice is welcome.

• brackets in php templates

  - by Othman

  I have a script, and now it's the perfect time to have an option to change theme templates. I was looking forward to store these files in php files, or html files. with CSS file. I looked over some codes and I found that they use brackets to refer to the variable. Here's an example of a template block: <div class='block_div'> <center>{title}</center> {content} </div> I know that I can use PHP vars usering <?=$var;?>. However, I think the one above is better, and I looked over the web to find anything about it but I couldn't. My Question is how I can use these brackets in my php or html code. to let the user changing the template only not the code!

• quick prototyping in project design & development

  - by lurscher

  i'm currently working on a project in my spare time (mostly 3-4 hours from monday to friday, and up to 6 hours on sundays) and i've found redmine very useful to hold a record of development tasks. However, there are some stuff, specially when you are trying to prototype or brainstorm a redesign of a set of related classes, that the best tool that i've found for this still is a sheet of paper and a pen. I want to understand if maybe i'm just short of getting to work properly with existing tools. Do you find the use of a notebook or a journal an unavoidable part of software design? are there better alternatives? how do you organize pen-and-paper work and other software management tools like redmine?

• What do I need to know about Data Structures and Algorithms in the "real" world

  - by Ray T Champion

  I just finished the data structures and algorithms course in school , I took it during the summer so 6wks course vs a 16 wk course during the regular semester. So not only was the course hard but it was really really really fast. My question is what do I need to know about data structures in the real world? I understand what they do and how they work, for the most part, but I had a real tough time coding them , I wouldn't be able to write the code for a binary tree class or a balanced tree class from scratch .... Is that bad? should I retake it , or is knowledge of how they work sufficient, without being able to write the classes from scratch?

• Is it possible for a web-server to send more files than requested for, and have the browser accept them?

  - by Osiris

  I've created a basic web server for a school project, and it serves static content without a problem. I thought of having the server parse all htm/html files for links to .js/.css/image files, and send these files to the client without these files being requested by the client later. eg. The browser requests: index.htm The server responds with intex.htm and image.jpg I modified the server to send two distinct http responses for a "GET /index.html HTTP1.1" (one for the html page and one for the image), but the browser ended up requesting the image when it was good and ready. Is there any way to bypass this? (use a multipart response, perhaps) Will these files be accepted by most browsers, or will they be rejected for security reasons?
