			<content:encoded><![CDATA[<p><a href="http://en.wikipedia.org/wiki/Domain-specific_programming_language" target="_blank">Domain Specific Languages</a> (DSLs) são um assunto cada vez mais comum no mundo do desenvolvimento de software. Não são novidades, mas começam a ser utilizadas de outras formas e ganhar notabilidade.</p>
<p>O Rails utiliza DSLs em peso, graças à natureza dinâmica do Ruby e sua flexibilidade.</p>
<p>Como <a href="http://www.akitaonrails.com/2007/12/4/algumas-notcias-da-semana" target="_blank">publicado</a> pelo Fábio Akita, a ThoughtWorks lançou, na semana passada, o primeiro episódio de seu podcast <a href="http://www.thoughtworks.com/what-we-say/podcasts.html" target="_blank">IT Matters</a>, falando justamente sobre DSLs. O podcast é muito interessante e conta com ninguém menos que o próprio <a href="http://www.thoughtworks.com/who-we-are/martin-fowler.html" target="_blank">Martin Fowler</a> e mais alguns membros de sua excelente equipe. Vale muito a pena conferir.</p>

Idealizado por mim e pelo <a href="http://nullius.blogspot.com/" target="_blank">Guilherme Alves</a> como parte do nosso TCC (sobre XP e Rails), não queríamos trazer para cá ninguém menos que os melhores nesses assuntos: <a href="http://www.improveit.com.br/vinicius">Vinícius Manhães Teles</a> e <a href="http://www.akitaonrails.com">Fábio Akita</a>.</p>

<p>
Foi um mês caótico, por assim dizer: conseguindo patrocínios, negociando com a universidade, encontrando um dia livre em comum na agenda dos palestrantes, divulgando, lidando com a incompetência de muitos que nos atrapalharam e, principalmente, contando com a ajuda de todos os que foram fundamentais para que o evento pudesse acontecer.</p>
<p>Agradecemos ao professor Eduardo Morgado, Thaís e Jekimim do <a href="http://www.ltia.fc.unesp.br/ltia2006/index.html" target="_blank">LTIA</a>, professor Marco Torres da Faculdade Fênix, André Ruz, nosso amigo e todos os outros que estou esquecendo agora, mas que vão me perdoar por isso, certo? <img src='http://s0.wp.com/wp-includes/images/smilies/icon_biggrin.gif' alt=':D' class='wp-smiley' /> </p>
<p>O evento foi um sucesso, tivemos aproximadamente 80 pessoas presentes. As palestras foram ótimas e tudo correu muito bem. Meus agradecimentos ao Vinícius e ao Akita, que também colaboraram muito para que conseguíssemos fazer isso acontecer. A &#8220;chacoalhada&#8221; das palestras já começa a dar frutos por aqui. Continuem o ótimo trabalho, desejo à vocês muito sucesso e espero que possamos nos encontrar pelos eventos Brasil à fora.</p>
<p>Um agradecimento muito especial à minha namorada, Talita. Seu apoio é sempre fundamental para mim.</p>
<blockquote><p>Sucesso parece ser, em grande parte, uma questão de continuar enquanto os outros desistiram &#8211; William Feather</p></blockquote>

			<content:encoded><![CDATA[<p>Começando pelo final: o software &#8220;corporativo&#8221; é feito para quem o compra, não para quem o utiliza.</p>
<p>Atualmente, até mesmo nas pequenas empresas brasileiras, permeia um pensamento bizarro: quanto mais processos, documentos, burocracia, horas extras e falta de transparência, melhor. É o chamado comportamento corporativo.</p>
<p>Em algum momento da história, sabe-se lá por qual motivo, as pessoas passaram a acreditar que todas as empresas devem copiar fielmente o modelo de trabalho das grandes corporações. Isso é compreensível até certo ponto, afinal, essas corporações &#8220;deram certo&#8221;. No entanto, é muito esquisito ver pequenas empresas, que deveriam se aproveitar dessa característica, se prejudicarem por adotar esse modelo.</p>
<p><span id="more-39"></span></p>
<p>Como diz Jason Fried, da <a href="http://www.37signals.com" target="_blank">37signals</a>, as grandes corporações objetivam vender software para as empresas da Fortune 500, mas as pequenas devem focar na &#8220;Fortune 5.000.000&#8243;, isto é, para que competir no mercado das grandes se há muito espaço para vender software para pequenas empresas e até mesmo para pessoas diretamente? É aqui que ganha muita força o conceito de <a href="http://en.wikipedia.org/wiki/Software_as_a_Service" target="_blank">Software as a Service</a> (SaaS &#8211; vale a pena ler sobre isso).</p>
<p>É muito mais fácil conseguir feedback quando se faz software para pessoas e pequenas empresas. O motivo? Você está lidando diretamente com o usuário do sistema. Já quando se desenvolve para grandes empresas, há uma clara separação: há aquele que compra o software e aquele que usa o software. Na grande maioria das vezes, o usuário só terá contato com o software já após sua implantação, durante o treinamento (quando existe).</p>
<p>Até mesmo os vendedores de software já têm táticas definidas para esses casos: eles nunca falam do software em si, mas sim o que as pessoas que têm o poder de compra do software querem ouvir. </p>
<p>O software (projeto ou produto) é comprado, montanhas de especificações são escritas e entregues aos desenvolvedores, o cronograma atrasa, o custo é duas vezes maior do que a estimativa, tudo é feito às pressas e, meses depois, o verdadeiro usuário tem um monstro em suas mãos. Aí então começam meses de correções, renegociações e toda a balela que já conhecemos.</p>
<p>Já passou da hora de repensarmos sobre isso. Como de praxe, o Brasil sempre fica para trás e só percebe as mudanças muito tempo depois. Em outros países, muitos empreendedores já perceberam isso e estão trilhando novos caminhos. Estamos entrando na &#8220;era das startups&#8221;. </p>
<p>Até quando nós ficaremos fora desse movimento?</p>

			<content:encoded><![CDATA[<p><a href="http://www.pivotalblabs.com/articles/2007/09/02/hasfinder-its-now-easier-than-ever-to-create-complex-re-usable-sql-queries" target="_blank">HasFinder</a> é uma extensão ao ActiveRecord criada por Nick Kallen, da <a href="http://www.pivotallabs.com/" target="_blank">Pivotal Labs</a>, que permite a flexibilização de métodos customizados de busca, ao estilo do que é possível fazer com <em>with_scope</em> ou com os plugins <em>scope_out</em> e <em>scope_proxy</em>.</p>
<p>A diferença é que o HasFinder permite o encadeamento de condições e também o uso das mesmas em associações. Exemplos:</p>
<p>Definindo os métodos de busca e suas condições:</p>
<pre class="brush: ruby;">
class Article  {:published =&gt; true}
  has_finder :popular, :conditions =&gt; ...
end
</pre>
<p>É possível encadeá-los ou usar outros métodos sobre eles:</p>
<pre class="brush: ruby;">
  Article.published.popular
  Article.published.popular.count
  Article.popular.find(:first)
</pre>
<p>Trabalhando com associações:</p>
<pre class="brush: ruby;">
class User
  has_many :articles
end

user.articles.popular.find(:first)
user.articles.published.popular.average(:view_count)
</pre>
<p>Também é possível estendê-los com blocos:</p>
<pre class="brush: ruby;">
class Article
  has_finder :unpublished :conditions =&gt; {:published =&gt; false} do
    def published_all
      find(:all).map(&amp;:publish)
    end
  end
end
</pre>
