Working With Rails

Get in the swing, pal
Get in the swing
With everybody and everything
(repeat)

My friends are here
Mind if you go out and not come back again
Well, thanks a lot
Hooray, hooray
The night is younger than the girl who's got the touch
But not by much

Well, I ain't no Freud, I'm from L.A.
But I know certain things
That they also serve who sit and wait
They're cheaper than painting
And don't need explaining

(Chorus)

When Salmon spawn
A ton of water blocks their motion,
Spoils their game
But on they go
Thrashing 'til their mission is fulfilled or else
Oh, but they have their friends
And have a warm bed waiting
Just like I do with you
I'm happy, so happy, I'm happy, oh happy

(Chorus)

All for one, one for all

(Chorus)

Hello down there
This is your creator with a questionaire
Hello up there
I don't have the time to fill out questionaires 

Bug no FCGI utilizando método POST com :multipart => true

by Vinicius Ebersol | about 3 hours ago | Read more

Ontem ao publicar uma demo no ar, penei para descobrir porque eu não conseguia criar um novo produto durante o teste da aplicação. Utilizando o WEBRick eu conseguia criar normalmente. Seria um problema de banco de dados ou da utilização da versão de alguma gem? Além disso, todos os outros formulários de criação funcionavam.

O que será então?

Se trata de um bug no FCGI. Simplesmente quando o método ultipart está definido como true, ao tentar cadastrar um dado novo no banco de dados, ele não consegue direcionar o POST para a action create do seu controller. A solução é simples e indolor. No seu form de new faça o seguinte:

<%= error_messages_for :product %>

<% form_for(:product, :url => "#{products_path}/", :html => { :multipart => true }) do %>

  <%= render :partial => 'form' %>

  <p>
    <%= submit_tag "Salvar" %>
  </p>
<% end %>

Note que no lugar de @products eu pus :product, :url => ”#{products_path}/”, isto porque o bug somente ocorre pela falta da barra após o nome do controller. Se a action do form estiver somente ”/products” ele irá entender que você quer acessar a action index e não o create. Com a barra no final da action tudo vai funcionar perfeitamente.

Qualquer dúvida, comente, talvez hajam soluções melhores.

O crédito para o descobrimento deste bug é para o Everton Carpes.

Keeping Up with the Information Flood

by Christopher Haupt | about 4 hours ago | Read more

The web is such a wonderful facilitator of publishing and communication that it’s almost impossible not to be chronically overwhelmed by the amount of information available.

I’ve been working on my information diet for years, having dropped most print newspapers a few years ago, then cut out most magazines, and more recently having worked toward an effective approach for dealing with the incredible amount of information available via RSS feeds.

Even if I were to focus my interest solely on startups, Ruby on Rails, marketing, writing, or photography, there’s far more content produced every day than I can hope to (or want to) read. Striking the right balance between reading enough to stay informed and find things of interest, but not so much that it takes too much time or feels burdensome, is a real challenge.

I’ve just posted an article on my evolving feed-reading habits over on my personal blog.

What’s your strategy?

Scharf, schärfer, pain food

by Peter Grosskopf | about 4 hours ago | Read more

Es gibt Leute die mögen es scharf, sehr scharf, so scharf das es schon weh tut. Es soll sogar Gourmets geben, die sich gleich ein Handtuch mitbestellen, damit sie sich zwischendurch die Schweißperlen von der Stirn wischen können. Wenn der Mexikaner um die Ecke mit seinem schärfsten Gericht den Schärfeliebenden nicht mehr beeindruckt, dann wird es vielleicht Zeit für Pain Food. Essen das so scharf ist, dass der normale Esser das Handtuch wirft. Das Essen kostet nicht nur Geld, sondern auch eine ordentliche Portion Mut und Überwindung. Manchmal kommt es vor, dass Übermütige anschließend in die Klinik gefahren werden müssen, weil ihnen nicht bekannt war, dass sie eine Allergie gegen Chili oder Knoblauch hatten. "Du denkst, Du könntest scharf essen,dann hast Du noch nie Pain-Food gegessen" denn Pain-Food wurde vom Tod kreiert! - so ein Zitat auf der Website der Pain-Food-Bude. Heute fand in Pirmasens (Pfalz) in der Pain-Food-Bude ein Pain Food Wettessen statt. Die Wettkämpfer mussten drei super-scharfe Gerichte essen. Nach den ersten beiden Speisen mit exodusartigen Soßen, gab es eine 5 Minuten Pause, in der ein scharfer Kaffee getrunken wurde, danach musste gleich das letzte Gericht gegessen werden. Bis jetzt konnte ich den Gewinner noch nicht in Erfahrung...

merb-auth, webrat, and merb_stories

by Jack Dempsey | about 4 hours ago | Read more

Recently I've been working on getting some stories written for www.recollectr.com and given that I just added in MerbAuth support, I thought now would be a good time to dive back into the previously paused process.

If you're interested in using webrat for merb_stories, you'll want to get the fork that supports merb from here:

http://github.com/gwynm/webrat/tree/master


I'd previously had some stories working with webrat and edge merb, but it looked like the upgrade to using MerbAuth in slice form broke some things. After some investigation I realized that the namespacing that's used in merb-slices was slightly different than what the merb supported fork of webrat was happy with...gwynm's fork adds a cookies= method to Application as follows:

class Application < Merb::Controller
  def cookies=(newcookies)
    @_cookies = newcookies
  end
end

This is fine except with MerbAuth, we have MerbAuth::Application, and as such things were busted a bit. So, doing the same for MerbAuth::Application fixed things right up:

module MerbAuth
  class Application < Merb::Controller
    def cookies=(newcookies)
      @_cookies = newcookies
    end
  end
end

Thing is, this doesn't exactly belong in MerbAuth as its specific to webrat....and it doesn't exactly belong in webrat as its going to be an issue to any merb-slice. So for the time being I have this in my app code, and things work nicely. I'll probably write a little more and maybe give some examples for general webrat and merb_stories usage, but til then hope this helps anyone else trying all three of these great components.

White Noise

by Dan Benjamin | about 4 hours ago | Read more

It’s a fact that silence, like the kind created by our sealed, insulated dwellings, is an unnatural condition with harmful side-effects. Sounds like white noise can be immensely helpful in creating positive background noise in an otherwise silent home or office. White noise is also useful in masking the unwanted noise from a noisy workplace or hotel. Babies and small children also benefit immensely from white noise, as the sounds they heard for 9 months in the womb are suddenly absent in the outside world.

SimplyNoise is a straight-forward browser app that creates user-adjustable white noise. Just move the slider to adjust the volume. New features, like “improved white noise” and downloadable MP3’s are on the way soon.

If you’d prefer a native application, check out Noise, a Mac OS X application that you can use to generate white or pink noise.

And if you want a real-life sound machine, the HoMedics SS-2000 isn’t bad for $20.

Bar Camp Gold Coast 1 - Mission Complete

by Steve Dalton | about 5 hours ago | Read more

About 30-40 people turned up to Bar Camp Gold Coast on a rainy Saturday at Griffith Uni (perfect weather for staying inside and talking tech). I was really encouraged by the quality of the people that attended... I always knew these people existed on the Gold Coast and I will now double my efforts to get more stuff like this happening on the coast.

Anyway - I'll blog about this in more detail later, but here are some of the things that we did.

• Mobile Coffee Guy - very popular. Thankyou Kerry - I will definitely use you again. I'll find your website and post here.
• Pizza - Eagle Boys were ok. But were pretty late and pizza was a little cold....
• Hardware giveaway.... got rid of a lot of my stuff. Hands shot up pretty quickly - so obviously people obviously wanted this stuff! Lots of other people brought stuff to give too.
• Apress Book/Tshirt giveaway - didn't know how to give these away in the end (best presentation was too hard to judge) so we did a door prize instead.
• Internet - Griffith Uni installed an AP especially for us, and we had use of the uni internet. Seemed pretty fast - although annoying to keep getting the login page after a time away
• Group photo - thanks DJ for getting this together.. good idea
• Linux area - we kept a little area with some Linux magazines, distros and flyers on and the GCLUG people seemed to gather around there and talk to people about Linux, seemed to work well.
• Tshirts - good number of shirts (I think we printed 38) - they nearly all went, and it was nice to see Linux on everyone's backs too (including some MS people :)). Thanks to Custom Tees for those.
• After drinks... we got about 10 people there.... Parkwood Tavern was pretty ok, had a good outdoor area - with heaters!

Twitter Litter

by James Britt | about 7 hours ago | Read more

I’ve noticed an increase in the use of folks adding a leading ’@’ character to user names (and even real names) in threaded discussion boards, mailing lists, and E-mail.

I don’t think any of the uses I’ve seen were meant to aid any sort of automated text processing; it appears to be a bad habit that perhaps makes sense on Twitter, but is merely line noise elsewhere.

Please consider: No Twitter Litter.

ets

by Ry Dahl | about 7 hours ago | Read more

ets, Erlang Term Storage, is great. It a simple memory hash for "very large quantities of data" on which more complex database systems are built (Mnesia, for example). The man page says, lookup, insertion, and removal are constant time operations.

I just reimplemented the back-end for my Caching Server to use ets and I'm very happy with the results. Code is simpler and the system is responding more quickly.

I must say - I'm extremely happy with Erlang so far.

Mac下面除了用虚拟文件夹系统安装应用程序外,还提供了ports来帮助你安装其他应用程序,跟BSD中的ports道理一样,将macports的使用方法记录在这里以备查:

安装macports
到这里下载最新的macports的Mac OS X Package(.pkg)安装包,安装过程没有什么特别,就像安装其他应用软件一样,需要注意的是一些系统需求一定要提前安装.

将/opt/local/bin和/opt/local/sbin添加到$PATH搜索路径中

原本port有个sync的功能,不过这个sync事实上是selfupdate的一部分,所以强烈建议用selfupdate来更新ports索引
sudo port selfupdate

搜索索引中的软件
port search app_name

安装新软件
sudo port install app_name

卸载软件
sudo port uninstall app_name

查看outdated的软件以及版本
port outdated

升级outdated的软件
sudo port upgrade outdated

Essa semana participei do II ESOL que aconteceu no CEFET-PE. Foi a minha primeira paticipação em um evento de software livre. Tentei passar um pouco do mundo Ruby e Rails com o intuito de consquistar alguns adeptos e fortalecer a nossa comunidade local. A palestra foi nos moldes do DHH. Fiz uma breve introdução ao Ruby e um hands on com Rails para mostrar as facilidades de utilizar o framework.

O evento estava muito bom e só tenho a agradecer ao pessoal da organização pelo apoio e atenção que me deram durante todo tempo que estive por lá.
