  • Sputnik – Google’s Java script conformance tester now as website

    - by samsudeen
    Sputnik the JavaScript 3 conformance test suite launched by Google last year is now available as Google Labs (Sputnik Test)product. You can browse it like any other  website and run over 5000 java script function tests to check your browser compatibility This product allows you do the following options Run :  You can run the complete test suite on your browser to check the compliance to  ECMA-262 standards.You can also browse trough  the failed test case. Compare : You can compare java script conformance of the various leading browsers in the market. Now web developers can be more cautious while designing websites to make them compatible with multiple browsers. Google is committed to review and release multiple version periodically with updated test cases. According to the latest sputnik test  result released by Google, Opera 10.5 leads the race with only 78 failures. Microsoft IE 8 performed the worst (463 failures) . Next to Opera,  Apple’s Safari (159 failures), Google’s Chrome (218 failures) and Mozilla’s Firefox (259 failures) leads respectively Though the test are about conformance, not performance, the top 3 leading browsers are among the last three in conformance which is something they have to improve Join us on Facebook to read all our stories right inside your Facebook news feed.

  • What is JavaScript, really?

    - by Lord Loh.
    All this started when I was looking for a way to test my webpage for JavaScript conformance like the W3C HTML Validator. I have not found one yet. So let me know if you know of any... I looked for the official JavaScript page and find ECMA Script. These people have standardized a scripting language (I do not feel like calling it JavaScript anymore!) and called it ECMA-262 (Wikipedia). Their latest work is Edition 5.1 JavaScript was developed my Mozilla Corporation and their last stable version is 1.8.5 (see this) which is based on the ECMA's edition 5.1 The Wikipedia page linked mentions dialects. Mozilla's JavaScript 1.8.5 is listed as a dialect along with JScript 9 (IE) and JavaScript (Chrome's V8[Wiki]) and a lot others. Am I to understand that JavaScript 1.8.5 is a derivative of the ECMA-262 and SpiderMonkey[Wiki] is an engine that runs it? And Chrome has its own dialect and V8 engine is the program that runs it? With all these dialects based off ECMA-262, what I can no longer understand is "What is JavaScript"? Are there any truly cross browser scripting languages? Do the various implementers come together to agree on the dialect cross compatibility? Is this effort ECMA?

  • Novo Suporte para Combinação e Minificação de Arquivos JavaScript e CSS (Série de posts sobre a ASP.NET 4.5)

    - by Leniel Macaferi
    Este é o sexto post de uma série de posts que estou escrevendo sobre a ASP.NET 4.5. Os próximos lançamentos do .NET e Visual Studio incluem vários novos e ótimos recursos e capacidades. Com a ASP.NET 4.5 você vai ver um monte de melhorias realmente emocionantes em formulários da Web ( Web Forms ) e MVC - assim como no núcleo da base de código da ASP.NET, no qual estas tecnologias são baseadas. O post de hoje cobre um pouco do trabalho que estamos realizando para adicionar suporte nativo para combinação e minificação de arquivos JavaScript e CSS dentro da ASP.NET - o que torna mais fácil melhorar o desempenho das aplicações. Este recurso pode ser utilizado por todas as aplicações ASP.NET, incluindo tanto a ASP.NET MVC quanto a ASP.NET Web Forms. Noções básicas sobre Combinação e Minificação Como mais e mais pessoas usando dispositivos móveis para navegar na web, está se tornando cada vez mais importante que os websites e aplicações que construímos tenham um bom desempenho neles. Todos nós já tentamos carregar sites em nossos smartphones - apenas para, eventualmente, desistirmos em meio à frustração porque os mesmos são carregados lentamente através da lenta rede celular. Se o seu site/aplicação carrega lentamente assim, você está provavelmente perdendo clientes em potencial por causa do mau desempenho/performance. Mesmo com máquinas desktop poderosas, o tempo de carregamento do seu site e o desempenho percebido podem contribuir enormemente para a percepção do cliente. A maioria dos websites hoje em dia são construídos com múltiplos arquivos de JavaScript e CSS para separar o código e para manter a base de código coesa. Embora esta seja uma boa prática do ponto de vista de codificação, muitas vezes isso leva a algumas consequências negativas no tocante ao desempenho geral do site. Vários arquivos de JavaScript e CSS requerem múltiplas solicitações HTTP provenientes do navegador - o que pode retardar o tempo de carregamento do site.  Exemplo Simples A seguir eu abri um site local no IE9 e gravei o tráfego da rede usando as ferramentas do desenvolvedor nativas do IE (IE Developer Tools) que podem ser acessadas com a tecla F12. Como mostrado abaixo, o site é composto por 5 arquivos CSS e 4 arquivos JavaScript, os quais o navegador tem que fazer o download. Cada arquivo é solicitado separadamente pelo navegador e retornado pelo servidor, e o processo pode levar uma quantidade significativa de tempo proporcional ao número de arquivos em questão. Combinação A ASP.NET está adicionando um recurso que facilita a "união" ou "combinação" de múltiplos arquivos CSS e JavaScript em menos solicitações HTTP. Isso faz com que o navegador solicite muito menos arquivos, o que por sua vez reduz o tempo que o mesmo leva para buscá-los. A seguir está uma versão atualizada do exemplo mostrado acima, que tira vantagem desta nova funcionalidade de combinação de arquivos (fazendo apenas um pedido para JavaScript e um pedido para CSS): O navegador agora tem que enviar menos solicitações ao servidor. O conteúdo dos arquivos individuais foram combinados/unidos na mesma resposta, mas o conteúdo dos arquivos permanece o mesmo - por isso o tamanho do arquivo geral é exatamente o mesmo de antes da combinação (somando o tamanho dos arquivos separados). Mas note como mesmo em uma máquina de desenvolvimento local (onde a latência da rede entre o navegador e o servidor é mínima), o ato de combinar os arquivos CSS e JavaScript ainda consegue reduzir o tempo de carregamento total da página em quase 20%. Em uma rede lenta a melhora de desempenho seria ainda maior. Minificação A próxima versão da ASP.NET também está adicionando uma nova funcionalidade que facilita reduzir ou "minificar" o tamanho do download do conteúdo. Este é um processo que remove espaços em branco, comentários e outros caracteres desnecessários dos arquivos CSS e JavaScript. O resultado é arquivos menores, que serão enviados e carregados no navegador muito mais rapidamente. O gráfico a seguir mostra o ganho de desempenho que estamos tendo quando os processos de combinação e minificação dos arquivos são usados ??em conjunto: Mesmo no meu computador de desenvolvimento local (onde a latência da rede é mínima), agora temos uma melhoria de desempenho de 40% a partir de onde originalmente começamos. Em redes lentas (e especialmente com clientes internacionais), os ganhos seriam ainda mais significativos. Usando Combinação e Minificação de Arquivos dentro da ASP.NET A próxima versão da ASP.NET torna realmente fácil tirar proveito da combinação e minificação de arquivos dentro de projetos, possibilitando ganhos de desempenho como os que foram mostrados nos cenários acima. A forma como ela faz isso, te permite evitar a execução de ferramentas personalizadas/customizadas, como parte do seu processo de construção da aplicação/website - ao invés disso, a ASP.NET adicionou suporte no tempo de execução/runtime para que você possa executar a combinação/minificação dos arquivos dinamicamente (cacheando os resultados para ter certeza de que a performance seja realmente satisfatória). Isto permite uma experiência de desenvolvimento realmente limpa e torna super fácil começar a tirar proveito destas novas funcionalidades. Vamos supor que temos um projeto simples com 4 arquivos JavaScript e 6 arquivos CSS: Combinando e Minificando os Arquivos CSS Digamos que você queira referenciar em uma página todas as folhas de estilo que estão dentro da pasta "Styles" mostrada acima. Hoje você tem que adicionar múltiplas referências para os arquivos CSS para obter todos eles - o que se traduziria em seis requisições HTTP separadas: O novo recurso de combinação/minificação agora permite que você combine e minifique todos os arquivos CSS da pasta Styles - simplesmente enviando uma solicitação de URL para a pasta (neste caso, "styles"), com um caminho adicional "/css" na URL. Por exemplo:    Isso fará com que a ASP.NET verifique o diretório, combine e minifique os arquivos CSS que estiverem dentro da pasta, e envie uma única resposta HTTP para o navegador com todo o conteúdo CSS. Você não precisa executar nenhuma ferramenta ou pré-processamento para obter esse comportamento. Isso te permite separar de maneira limpa seus estilos em arquivos CSS separados e condizentes com cada funcionalidade da aplicação mantendo uma experiência de desenvolvimento extremamente limpa - e mesmo assim você não terá um impacto negativo de desempenho no tempo de execução da aplicação. O designer do Visual Studio também vai honrar a lógica de combinação/minificação - assim você ainda terá uma experiência WYSWIYG no designer dentro VS. Combinando e Minificando os Arquivos JavaScript Como a abordagem CSS mostrada acima, se quiséssemos combinar e minificar todos os nossos arquivos de JavaScript em uma única resposta, poderíamos enviar um pedido de URL para a pasta (neste caso, "scripts"), com um caminho adicional "/js":   Isso fará com que a ASP.NET verifique o diretório, combine e minifique os arquivos com extensão .js dentro dele, e envie uma única resposta HTTP para o navegador com todo o conteúdo JavaScript. Mais uma vez - nenhuma ferramenta customizada ou etapas de construção foi necessária para obtermos esse comportamento. Este processo funciona em todos os navegadores. Ordenação dos Arquivos dentro de um Pacote Por padrão, quando os arquivos são combinados pela ASP.NET, eles são ordenados em ordem alfabética primeiramente, exatamente como eles são mostrados no Solution Explorer. Em seguida, eles são automaticamente reorganizados de modo que as bibliotecas conhecidas e suas extensões personalizadas, tais como jQuery, MooTools e Dojo sejam carregadas antes de qualquer outra coisa. Assim, a ordem padrão para a combinação dos arquivos da pasta Scripts, como a mostrada acima será: jquery-1.6.2.js jquery-ui.js jquery.tools.js a.js Por padrão, os arquivos CSS também são classificados em ordem alfabética e depois são reorganizados de forma que o arquivo reset.css e normalize.css (se eles estiverem presentes na pasta) venham sempre antes de qualquer outro arquivo. Assim, o padrão de classificação da combinação dos arquivos da pasta "Styles", como a mostrada acima será: reset.css content.css forms.css globals.css menu.css styles.css A ordenação/classificação é totalmente personalizável, e pode ser facilmente alterada para acomodar a maioria dos casos e qualquer padrão de nomenclatura que você prefira. O objetivo com a experiência pronta para uso, porém, é ter padrões inteligentes que você pode simplesmente usar e ter sucesso com os mesmos. Qualquer número de Diretórios/Subdiretórios é Suportado No exemplo acima, nós tivemos apenas uma única pasta "Scripts" e "Styles" em nossa aplicação. Isso funciona para alguns tipos de aplicação (por exemplo, aplicações com páginas simples). Muitas vezes, porém, você vai querer ter múltiplos pacotes/combinações de arquivos CSS/JS dentro de sua aplicação - por exemplo: um pacote "comum", que tem o núcleo dos arquivos JS e CSS que todas as páginas usam, e então arquivos específicos para páginas ou seções que não são utilizados globalmente. Você pode usar o suporte à combinação/minificação em qualquer número de diretórios ou subdiretórios em seu projeto - isto torna mais fácil estruturar seu código de forma a maximizar os benefícios da combinação/minificação dos arquivos. Cada diretório por padrão pode ser acessado como um pacote separado e endereçável através de uma URL.  Extensibilidade para Combinação/Minificação de Arquivos O suporte da ASP.NET para combinar e minificar é construído com extensibilidade em mente e cada parte do processo pode ser estendido ou substituído. Regras Personalizadas Além de permitir a abordagem de empacotamento - baseada em diretórios - que vem pronta para ser usada, a ASP.NET também suporta a capacidade de registrar pacotes/combinações personalizadas usando uma nova API de programação que estamos expondo.  O código a seguir demonstra como você pode registrar um "customscript" (script personalizável) usando código dentro da classe Global.asax de uma aplicação. A API permite que você adicione/remova/filtre os arquivos que farão parte do pacote de maneira muito granular:     O pacote personalizado acima pode ser referenciado em qualquer lugar dentro da aplicação usando a referência de <script> mostrada a seguir:     Processamento Personalizado Você também pode substituir os pacotes padrão CSS e JavaScript para suportar seu próprio processamento personalizado dos arquivos do pacote (por exemplo: regras personalizadas para minificação, suporte para Saas, LESS ou sintaxe CoffeeScript, etc). No exemplo mostrado a seguir, estamos indicando que queremos substituir as transformações nativas de minificação com classes MyJsTransform e MyCssTransform personalizadas. Elas são subclasses dos respectivos minificadores padrão para CSS e JavaScript, e podem adicionar funcionalidades extras:     O resultado final desta extensibilidade é que você pode se plugar dentro da lógica de combinação/minificação em um nível profundo e fazer algumas coisas muito legais com este recurso. Vídeo de 2 Minutos sobre Combinação e Minificacão de Arquivos em Ação Mads Kristensen tem um ótimo vídeo de 90 segundo (em Inglês) que demonstra a utilização do recurso de Combinação e Minificação de Arquivos. Você pode assistir o vídeo de 90 segundos aqui. Sumário O novo suporte para combinação e minificação de arquivos CSS e JavaScript dentro da próxima versão da ASP.NET tornará mais fácil a construção de aplicações web performáticas. Este recurso é realmente fácil de usar e não requer grandes mudanças no seu fluxo de trabalho de desenvolvimento existente. Ele também suporta uma rica API de extensibilidade que permite a você personalizar a lógica da maneira que você achar melhor. Você pode facilmente tirar vantagem deste novo suporte dentro de aplicações baseadas em ASP.NET MVC e ASP.NET Web Forms. Espero que ajude, Scott P.S.

  • Creating a DNS Server

    - by c.adhityaa
    OK, I am a complete newbie to all this, so please bear with me. I want to create a DNS Server (like Google does - 8.8.8.8). I understand that a DNS Server is a Server that gives a IP on being given a hostname, ie. when I ask it what is the IP of google.com, it says "64.233.160.0". So, what I want to do is create a similar one that holds records of what translates to what. I thought of this since it looks to be similar to a webserver - ask for a page and it gives back the page. That is, when my machine has the IP xxx.xxx.xxx.xxx and people chose xxx.xxx.xxx.xxx as their Primary DNS Server, then when they ask "www.google.com", I sould be able to tell "64.233.160.0". So, how do I create this DNS Server that is accessible to everyone in the world ? It would be easier if we have something like EasyPHP which is the analogue to a webserver here. I am sorry if I have caused any trauma because this might seem rubbish to experts ;) Adhityaa

  • Microsoft’s Contribution to jQuery – Client Templating

    - by joelvarty
    I am interested to see the community’s response to Microsoft’s contributions to jQuery.  I have been using jTemplates on and off in my apps for a while, but I will certainly check out the new templating plugins put forth by MS and explained here by Scott Guthrie. It may be that some are against the very idea of a company like Microsoft being involved with jQuery, and Scott explains the process with the following: “jQuery has a fantastic developer community, and a very open way to propose suggestions and make contributions.  Microsoft is following the same process to contribute to jQuery as any other member of the community.” I think we can take this in one of two ways:  It’s great that Microsoft sees themselves as a part of a greater community that they can support. It’s the first step in Microsoft’s attempt to usurp the community and have greater control over the web, it’s standards, and it’s developer community. Personally, I believe Microsoft sees the world (and the web) differently from how they did back when IE had more than %80 of the browser market.  Now, in order to keep it’s development products relevant, they are pushing Asp.Net (as they have been for a few years) towards a more open strategy that’s more “web-like” in my opinion. These contributions to jQuery are a good thing, I think.  Now, let’s go try out these new plug-ins and see if they stack up… more later - joel

  • Google Updates Google Pack – Pushes Firefox and Skype Away

    - by Gopinath
    Google Pack is a must to install software package on every new Windows PC. With a single installer Google Pack delivers all the useful Google applications like Gtalk, Google Earth, Picasa, etc. and third party applications Firefox, Skype, Adobe Reader. Today Google updated Google Pack collection and removed competitor products like Firefox and Skype from main page and pushed them to background. The main page of Google Pack now showcases the following software: Google Apps, Google Picasa, Adobe Reader, Google Toolbar for IE, Google Desktop, avast free antivirus, Google Chrome and Google Earth. It’s still possible to install Firefox and Skype through Google Pack by clicking on the link “All Applicatoins” available on the right side menu and selecting the required installers.  As most of the users use the main page to pick the showcased software, Firefox and Skype are going to loose much of Google Pack love. Thanks labnol This article titled,Google Updates Google Pack – Pushes Firefox and Skype Away, was originally published at Tech Dreams. Grab our rss feed or fan us on Facebook to get updates from us.

  • Creating a Dynamic DataRow for easier DataRow Syntax

    - by Rick Strahl
    I've been thrown back into an older project that uses DataSets and DataRows as their entity storage model. I have several applications internally that I still maintain that run just fine (and I sometimes wonder if this wasn't easier than all this ORM crap we deal with with 'newer' improved technology today - but I disgress) but use this older code. For the most part DataSets/DataTables/DataRows are abstracted away in a pseudo entity model, but in some situations like queries DataTables and DataRows are still surfaced to the business layer. Here's an example. Here's a business object method that runs dynamic query and the code ends up looping over the result set using the ugly DataRow Array syntax:public int UpdateAllSafeTitles() { int result = this.Execute("select pk, title, safetitle from " + Tablename + " where EntryType=1", "TPks"); if (result < 0) return result; result = 0; foreach (DataRow row in this.DataSet.Tables["TPks"].Rows) { string title = row["title"] as string; string safeTitle = row["safeTitle"] as string; int pk = (int)row["pk"]; string newSafeTitle = this.GetSafeTitle(title); if (newSafeTitle != safeTitle) { this.ExecuteNonQuery("update " + this.Tablename + " set safeTitle=@safeTitle where pk=@pk", this.CreateParameter("@safeTitle",newSafeTitle), this.CreateParameter("@pk",pk) ); result++; } } return result; } The problem with looping over DataRow objecs is two fold: The array syntax is tedious to type and not real clear to look at, and explicit casting is required in order to do anything useful with the values. I've highlighted the place where this matters. Using the DynamicDataRow class I'll show in a minute this code can be changed to look like this:public int UpdateAllSafeTitles() { int result = this.Execute("select pk, title, safetitle from " + Tablename + " where EntryType=1", "TPks"); if (result < 0) return result; result = 0; foreach (DataRow row in this.DataSet.Tables["TPks"].Rows) { dynamic entry = new DynamicDataRow(row); string newSafeTitle = this.GetSafeTitle(entry.title); if (newSafeTitle != entry.safeTitle) { this.ExecuteNonQuery("update " + this.Tablename + " set safeTitle=@safeTitle where pk=@pk", this.CreateParameter("@safeTitle",newSafeTitle), this.CreateParameter("@pk",entry.pk) ); result++; } } return result; } The code looks much a bit more natural and describes what's happening a little nicer as well. Well, using the new dynamic features in .NET it's actually quite easy to implement the DynamicDataRow class. Creating your own custom Dynamic Objects .NET 4.0 introduced the Dynamic Language Runtime (DLR) and opened up a whole bunch of new capabilities for .NET applications. The dynamic type is an easy way to avoid Reflection and directly access members of 'dynamic' or 'late bound' objects at runtime. There's a lot of very subtle but extremely useful stuff that dynamic does (especially for COM Interop scenearios) but in its simplest form it often allows you to do away with manual Reflection at runtime. In addition you can create DynamicObject implementations that can perform  custom interception of member accesses and so allow you to provide more natural access to more complex or awkward data structures like the DataRow that I use as an example here. Bascially you can subclass DynamicObject and then implement a few methods (TryGetMember, TrySetMember, TryInvokeMember) to provide the ability to return dynamic results from just about any data structure using simple property/method access. In the code above, I created a custom DynamicDataRow class which inherits from DynamicObject and implements only TryGetMember and TrySetMember. Here's what simple class looks like:/// <summary> /// This class provides an easy way to turn a DataRow /// into a Dynamic object that supports direct property /// access to the DataRow fields. /// /// The class also automatically fixes up DbNull values /// (null into .NET and DbNUll to DataRow) /// </summary> public class DynamicDataRow : DynamicObject { /// <summary> /// Instance of object passed in /// </summary> DataRow DataRow; /// <summary> /// Pass in a DataRow to work off /// </summary> /// <param name="instance"></param> public DynamicDataRow(DataRow dataRow) { DataRow = dataRow; } /// <summary> /// Returns a value from a DataRow items array. /// If the field doesn't exist null is returned. /// DbNull values are turned into .NET nulls. /// /// </summary> /// <param name="binder"></param> /// <param name="result"></param> /// <returns></returns> public override bool TryGetMember(GetMemberBinder binder, out object result) { result = null; try { result = DataRow[binder.Name]; if (result == DBNull.Value) result = null; return true; } catch { } result = null; return false; } /// <summary> /// Property setter implementation tries to retrieve value from instance /// first then into this object /// </summary> /// <param name="binder"></param> /// <param name="value"></param> /// <returns></returns> public override bool TrySetMember(SetMemberBinder binder, object value) { try { if (value == null) value = DBNull.Value; DataRow[binder.Name] = value; return true; } catch {} return false; } } To demonstrate the basic features here's a short test: [TestMethod] [ExpectedException(typeof(RuntimeBinderException))] public void BasicDataRowTests() { DataTable table = new DataTable("table"); table.Columns.Add( new DataColumn() { ColumnName = "Name", DataType=typeof(string) }); table.Columns.Add( new DataColumn() { ColumnName = "Entered", DataType=typeof(DateTime) }); table.Columns.Add(new DataColumn() { ColumnName = "NullValue", DataType = typeof(string) }); DataRow row = table.NewRow(); DateTime now = DateTime.Now; row["Name"] = "Rick"; row["Entered"] = now; row["NullValue"] = null; // converted in DbNull dynamic drow = new DynamicDataRow(row); string name = drow.Name; DateTime entered = drow.Entered; string nulled = drow.NullValue; Assert.AreEqual(name, "Rick"); Assert.AreEqual(entered,now); Assert.IsNull(nulled); // this should throw a RuntimeBinderException Assert.AreEqual(entered,drow.enteredd); } The DynamicDataRow requires a custom constructor that accepts a single parameter that sets the DataRow. Once that's done you can access property values that match the field names. Note that types are automatically converted - no type casting is needed in the code you write. The class also automatically converts DbNulls to regular nulls and vice versa which is something that makes it much easier to deal with data returned from a database. What's cool here isn't so much the functionality - even if I'd prefer to leave DataRow behind ASAP -  but the fact that we can create a dynamic type that uses a DataRow as it's 'DataSource' to serve member values. It's pretty useful feature if you think about it, especially given how little code it takes to implement. By implementing these two simple methods we get to provide two features I was complaining about at the beginning that are missing from the DataRow: Direct Property Syntax Automatic Type Casting so no explicit casts are required Caveats As cool and easy as this functionality is, it's important to understand that it doesn't come for free. The dynamic features in .NET are - well - dynamic. Which means they are essentially evaluated at runtime (late bound). Rather than static typing where everything is compiled and linked by the compiler/linker, member invokations are looked up at runtime and essentially call into your custom code. There's some overhead in this. Direct invocations - the original code I showed - is going to be faster than the equivalent dynamic code. However, in the above code the difference of running the dynamic code and the original data access code was very minor. The loop running over 1500 result records took on average 13ms with the original code and 14ms with the dynamic code. Not exactly a serious performance bottleneck. One thing to remember is that Microsoft optimized the DLR code significantly so that repeated calls to the same operations are routed very efficiently which actually makes for very fast evaluation. The bottom line for performance with dynamic code is: Make sure you test and profile your code if you think that there might be a performance issue. However, in my experience with dynamic types so far performance is pretty good for repeated operations (ie. in loops). While usually a little slower the perf hit is a lot less typically than equivalent Reflection work. Although the code in the second example looks like standard object syntax, dynamic is not static code. It's evaluated at runtime and so there's no type recognition until runtime. This means no Intellisense at development time, and any invalid references that call into 'properties' (ie. fields in the DataRow) that don't exist still cause runtime errors. So in the case of the data row you still get a runtime error if you mistype a column name:// this should throw a RuntimeBinderException Assert.AreEqual(entered,drow.enteredd); Dynamic - Lots of uses The arrival of Dynamic types in .NET has been met with mixed emotions. Die hard .NET developers decry dynamic types as an abomination to the language. After all what dynamic accomplishes goes against all that a static language is supposed to provide. On the other hand there are clearly scenarios when dynamic can make life much easier (COM Interop being one place). Think of the possibilities. What other data structures would you like to expose to a simple property interface rather than some sort of collection or dictionary? And beyond what I showed here you can also implement 'Method missing' behavior on objects with InvokeMember which essentially allows you to create dynamic methods. It's all very flexible and maybe just as important: It's easy to do. There's a lot of power hidden in this seemingly simple interface.

  • What are the reasons why Clojure is hyped and PicoLisp widely ignored?

    - by Thorsten
    I recently discovered the Lisp family of programming languages, and it's definitely one of the more diverse and widespread families in the programming language world. I like Elisp because that most wonderful tool Emacs is an Elisp interpreter. But I was looking for one more Lisp dialect to learn and thought Clojure would be the obvious choice nowadays - until I discovered the well hidden gem PicoLisp. That must be the most intelligent programming environment I have ever seen, like taking the best ideas from Lisp and Smalltalk and adding performance and practicability - and the beauty of parsimony. There is even an Emacs-mode for it. PicoLisp must be the productivity world champion when it comes to building business applications with database and web-client - and that's a very common task. It seems that throwing more and more hardware cores at your PicoLisp application makes it faster and faster, and the database is very performant anyway. However, reactions to PicoLisp in in general mailing-lists etc. are almost hostile (envy?), and there is absolutely no hype and very little publicity (ie not one book published). Are there real justified reasons for this (except the vast amount of java-libs accessible by Clojure, I know that one)? Or is the mainstream it getting wrong again (see C vs Lisp, Java vs Smalltalk, Windows vs Linux) and will come to the conclusion 10 years later that the JVM was good as in between solution, but a really fast Lisp interpreter on multicore machines is much better and allows much cleaner concepts? PS 1: Please note: I'm not interested in Scheme or any Common Lisp dialect, although they might be fine languages. It's just PicoLisp vs Clojure. PS 2: another thing I like about PicoLisp is its similarity to Elisp in certain aspects (both are descendants from MacLisp?) - it's easier to learn two similar languages. There is so much "dynamic binding bashing" on the web, but two of the most appealing Lisp applications use it.

  • Safari Mobile Multi-Line <Select> aka GWT Multi-Line ListBox

    - by McTrafik
    Hi guys. Working on a webapp here that must run on the iPad (so, Safari Mobile). I have this code that works fine in just about anything except iPad: <select class="gwt-ListBox" size="12" multiple="multiple"> <option value="Bleeding Eyelashes">Bleeding Eyelashes</option> <option value="Smelly Pupils">Smelly Pupils</option> <option value="Bushy Eyebrows">Bushy Eyebrows</option> <option value="Green Vessels">Green Vessels</option> <option value="Sucky Noses">Sucky Noses</option> </select> What it's supposed to look like is a box with 12 lines ans 5 of them filled up. It works fine in FF, IE, Chrome, Safari Win. But, when I open it on iPad, it's just a single line! Styling it with CSS doesn't work. It just makes the single line bigger if I set the height. Is there a way to make it behave the same way as in normal browsers, or do I nave to make a custom component? Thanks.

  • The Best Tips and Tweaks for Getting the Most Out of Internet Explorer 9

    - by Lori Kaufman
    If you use Internet Explorer 9, we have many tips and tricks for you to improve your web surfing experience, from customizing the interface to using the many features, and to make your time online more secure with IE9’s many security and privacy enhancements. Surf or Search Using the One Box (Address Bar) In IE versions prior to 9, the address bar and search bar were separate. They are now combined into the One Box in IE9, allowing you to navigate to websites or start a search from a single place. According to Microsoft, if you enter a single word that represents a valid URL, such as “microsoft” or “howtogeek,” the word will be evaluated as a URL and you can click on the URL or press Shift + Enter to load that site. The One Box also provides inline autocomplete functionality, so you only have to type a few letters to quickly get to your favorite sites. IE9 autocompletes what you are typing with popular websites, as well as with items from your Favorites and History lists. HTG Explains: What Is Windows RT and What Does It Mean To Me?

  • Keep basic game physics separate from basic game object? [on hold]

    - by metamorphosis
    If anybody has dealt with a similar situation I'd be interested in your experience/wisdom, I'm developing a 2D game library in C++, I have game objects which have very basic physics, they also have movement classes attached to differing states, for example, a different movement type based on whether the character is jumping, on ice, whatever. In terms of storing velocity and acceleration impulses, are they best held by the object? Or by the associated movement class? The reason I ask is that I can see advantages to both approaches- if you store physics data in the movement class, you have to pass physics information between class instances when a state change occurs (ie. impulses, gravity etc) but the class has total control over whether those physics are updated or not. An obvious example of how this would be useful was if an object was affected by something which caused it to ignore gravity, or something like that. on the other hand if you store the physics data in the object class, it feels more logical, you don't have to go around passing physics impulses and gravity etc, however the control that the movement class has over the object's physics becomes more convoluted. Basically the difference is between: object->physics stacks (acceleration impulses etc) ->physics functions ->movement type <-movement type makes physics function calls through object and object->movement type->physics stacks ->physics functions ->object forwards external physics calls onto movement type ->object transfers physics stacks between movement types when state change occurs Are there best practices here?

  • Overriding GetHashCode in a mutable struct - What NOT to do?

    - by Kyle Baran
    I am using the XNA Framework to make a learning project. It has a Point struct which exposes an X and Y value; for the purpose of optimization, it breaks the rules for proper struct design, since its a mutable struct. As Marc Gravell, John Skeet, and Eric Lippert point out in their respective posts about GetHashCode() (which Point overrides), this is a rather bad thing, since if an object's values change while its contained in a hashmap (ie, LINQ queries), it can become "lost". However, I am making my own Point3D struct, following the design of Point as a guideline. Thus, it too is a mutable struct which overrides GetHashCode(). The only difference is that mine exposes and int for X, Y, and Z values, but is fundamentally the same. The signatures are below: public struct Point3D : IEquatable<Point3D> { public int X; public int Y; public int Z; public static bool operator !=(Point3D a, Point3D b) { } public static bool operator ==(Point3D a, Point3D b) { } public Point3D Zero { get; } public override int GetHashCode() { } public override bool Equals(object obj) { } public bool Equals(Point3D other) { } public override string ToString() { } } I have tried to break my struct in the way they describe, namely by storing it in a List<Point3D>, as well as changing the value via a method using ref, but I did not encounter they behavior they warn about (maybe a pointer might allow me to break it?). Am I being too cautious in my approach, or should I be okay to use it as is?

  • How to use semantic markup and Google Places to assist in local search SEO?

    - by ElHaix
    In this article, adding additional localized markup is supposed to help your site's SEO. ie. <div itemscope itemtype="http://data-vocabulary.org/Organization"> <span itemprop="name">Search Engine People</span> <span itemprop="address" itemscope itemtype="http://data-vocabulary.org/Address"> <span itemprop="street-address">100 Westney Road South Unit 200, Building E</span> <span itemprop="locality">Ajax</span>, <span itemprop="region">ON</span> <span itemprop="country-name">Canada</span> <span itemprop="postal-code">L1S 7H3</span> </div> What about a site that contains valid localized results, where the actual business location is not relevant. For example, a site with valid local results from San Francisco, CA and Phoenix, AZ. Should these tags be added to the localized results, and has anyone got any experience with how much adding these tags have improved results? In terms of Google Places, however, they seem to ask for the business' actual physical location. Is there a way to use Google Places in the aforementioned example to assist in SEO?

  • Growing Into Enterprise Architecture

    - by pat.shepherd
    I am writing this post as I am in an Enterprise Architecture class, specifically on the Oracle Enterprise Architecture Framework (OEAF).  I have been a long believer that SOA’s key strength is that it is the first IT approach that blends or unifies business and technology.  That is a common view and is certainly valid but is not completely true (or at least accurate).  As my personal view of EA is growing, I realize more than ever that doing EA is FAR MORE than creating a reference architecture, creating a physical architecture or picking a technology to standardize on.  Those are parts of the puzzle but not the whole puzzle by any stretch. I am now a firm believer that the various EA frameworks out there provide the rigor and structure required to allow the bridging of business strategy / vision to IT strategy / vision. The flow goes something like this: Business Strategy –> Business / Application / Information / Technology Architecture –> SOA Reference Architecture –> SOA Functional Architecture.  Governance is imbued throughout to help map, measure and verify the business-to-IT coherence. With those in place, then (and only then) can SOA fulfill it’s potential to be more that an integration strategy, more than a reuse strategy; but also a foundation for tying the results of IT to business vision. Fortunately, EA is a an ongoing process that it is never too late to get started with an understanding of frameworks such as TOGAF, FEA, or OEAF.  Also, EA is never ending in that it always needs to be apply, even once a full-blown Enterprise Architecture is established it needs to be constantly evolved.  For those who are getting deeper into EA as a discipline, there is plenty runway to grow as your company/customer begins to look more seriously at EA. I will close with a pointer to a Great Book I have recently read on this subject: Enterprise Architecture as Strategy (http://www.amazon.com/Enterprise-Architecture-Strategy-Foundation-Execution/dp/1591398398/ref=sr_1_1?ie=UTF8&s=books&qid=1268842865&sr=1-1)

  • A standard style guide or best-practice guide for web application development

    - by gutch
    I run a very small team of developers on a web application, just three people (and not even full time). We're all capable developers, but we write our code in very different ways: we name similar things in different ways, we use different HTML and CSS to achieve similar outcomes. We can manage this OK because we're small, but can't help feeling it would be better to get some standards in place. Are there any good style guides or best-practice guides for web application development that we can use to keep our code under control? Sure, we could write them ourselves. But the reality is that with lots to do and very few staff, we're not going to bother. We need something off the shelf that we can tinker with rather than start from scratch. What we're not looking for here is basic code formatting rules like "whether to use tabs or spaces" or "where to put line breaks" — we can control this by standardising our IDEs. What we are looking for are rules for code and markup. For example: What HTML markup should be used for headers, tables, sidebars, buttons, etc. When to add new CSS styles, and what to name them When IDs should be allocated to HTML elements, and what to name them How Javascript functions should be declared and called How to pick an appropriate URL for given page or AJAX call When to use each HTTP method, ie POST vs GET vs PUT etc How to name server-side methods (Java, in our case) How to throw and handle errors and exceptions in a consistent way etc, etc.

    Screenshot / Code Snippet About This small bookmarklet will allow anyone to use the "vulnerability" of the API that it allows you to check the up/down vote count - a feat you could normally achieve by being a 1k+rep user. Mainly useful for sites where you don't have this amount of rep, but want to check the stats of the more controversial questions (usually on meta) No API key is actually used here, but it's trivial to add one.

  • Render rivers in a grid.

    - by Gabriel A. Zorrilla
    I have created a random height map and now i want to create rivers. I've made an algorithm based on a* to make rivers flow from peaks to sea and now i'm in the quest of figuring out an elegant algorithm to render them. It's a 2D, square, mapgrid. The cells which the river pases has a simple integer value with this form :rivernumber && pointOrder. Ie: 10, 11, 12, 13, 14, 15, 16...1+N for the first river, 20,21,22,23...2+N for the second, etc. This is created in the map grid generation time and it's executed just once, when the world is generated. I wanted to treat each river as a vector, but there is a problem, if the same river has branches (because i put some noise to generate branches), i can not just connect the points in order. The second alternative is to generate a complex algorithm where analizes each point, checks if the next is not a branch, if so trigger another algorithm that take care of the branch then returns to the main river, etc. Very complex and inelegant. Perhaps there is a solution in the world generation algorithm or in the river rendering algorithm that is commonly used in these cases and i'm not aware of. Any tips? Thanks!!

  • GPLv2 - Multiple AI chess engines to bypass GPL

    - by Dogbert
    I have gone through a number of GPL-related questions, the most recent being this one: http://stackoverflow.com/questions/3248823/legal-question-about-the-gpl-license-net-dlls/3249001#3249001 I'm trying to see how this would work, so bear with me. I have a simple GUI interface for a game of Chess. It essentially can send/receive commands to/from an external chess engine (ie: Tong, Fruit, etc). The application/GUI is similar in nature to XBoard ( http://www.gnu.org/software/xboard/ ), but was independently designed. After going through a number of threads on this topic, it seems that the FSF considers dynamically linking against a GPLv2 library as a derivative work, and that by doing so, the GPLv2 extends to my proprietary code, and I must release the source to my entire project. Other legal precedents indicate the opposite, and that dynamic linking doesn't cause the "viral" effect of the GPL to propagate to my proprietary code. Since there is no official consensus that can give a "hard-and-fast" answer to the dynamic linking question, would this be an acceptable alternative: I build my chess GUI so that it sends/receives the chess engine AI logic as text commands from an external interface library that I write The interface library I wrote itself is then released under the GPL The interface library is only used to communicate via a generic text pipe to external command-line chess engines The chess engine itself would be built as a command-line utility rather than as a library of any sort, and just sends strings in the Universal Chess Interface of Chess Engine Communication Protocol ( http://en.wikipedia.org/wiki/Chess_Engine_Communication_Protocol ) format. The one "gotcha" is that the interface library should not be specific to one single GPL'ed chess engine, otherwise the entire GUI would be "entirely dependent" on it. So, I just make my interface library so that it is able to connect to any command-line chess engine that uses a specific format, rather than just one unique engine. I could then include pre-built command-line-app versions of any of the chess engines I'm using. Would that sort of approach allow me to do the following: NOT release the source for my UI Release the source of the interface library I built (if necessary) Use one or more chess engines and bundle them as external command-line utilities that ship with a binary version of my UI Thank you.
