A new year, a new Codebits event by the incredible Sapo Team.
I will be attending the event once again in November’12,
now that the participation was accepted for the event.
The venue is amazing, see by yourself.
Its about code, programming, web, internet, networking.
“Ritchie was best known as the creator of the C programming language and a key developer of the Unix operating system, and as co-author of the definitive book on C, The C Programming Language, commonly referred to as K&R (in reference to the authors Kernighan and Ritchie).”
Farewell Dennis Ritchie, your work changed my life.

Dear Steve, its not easy to “Stay Hungry. Stay Foolish”… damn, it isn’t. It’s not even fun most of the time. But when it is, it certainly rocks and pays up connecting all the dots left behind. Rest in peace.

jQuery.data( element,key,value )
“Store arbitrary data associated with the specified element. Returns the value that was set”
.data( key,value )
“Store arbitrary data associated with the matched elements.”
Performance difference: on this jsPerf test the last is about 84% slower.
So instead of:
$(’#element’).data(’type’, ‘critical’)
prefer:
jQuery.data(’#element’, ‘type’, ‘critical’)

After re-reading Google Code - Page Speed - Optimize Caching section, I began implementing it on the Sinatra app part of our eClinic.Pro system. Later, after having it working, I found out that Sinatra has this amazing helper:
# File ‘lib/sinatra/base.rb’, line 290
def last_modified(time)
return unless time
time = time_for time
response[’Last-Modified’] = time.httpdate
# compare based on seconds since […]
For the sake of application decoupling on one of the Merb web apps we’re working on, we identified the separation of blocks that shouldn’t depend on each other, with the advantage of having fewer dependencies, and lower the risk of malfunction in one part of a system when the other part is changed.
So a […]

Install notes for PosgreSQL 8.4 install using the great
Homebrew by Adam Vandenberg.
Run the author’s installation script, and that’s it. Try:
$ brew help
$ brew search postgresql
$ brew install postgresql

My advice ? Use Homebrew. True UNIX […]

Subject: [RubyForge] Gem index has been shut down
Hello -
You’re receiving this email because you’re a RubyForge project admin and a recent change robably affects you.
A few days ago we repointed gems.rubyforge.org to the gemcutter.org box. This means that Nick Quaranto’s excellent gemcutter app is now […]
its next week, yet fun starts much sooner; conference; talks; code; lisbon; 3day => codebits
Just like last year a lot of hacks and experiments are expected.
Kudos to the SAPO team, the organisers, to build up such an impressive event.
Last saturday the local Linux group, PortoLinux had a meeting at the engineering faculty of Porto University to discuss about usage of diferent SCM’s.
Main systems covered, centralized vs distributed:
- Subversion
- Git
It was a good tech event, spent a good time there.
Some photos here.

BTW, the project site of Tokyo products have been moved onto my own server.

Though it has not been completed yet, I’ll write more English information about Tokyo products.”
So, to get the latest, head there.
Scripting definition files (sdefs) are XML files that describe everything
about an application scripting interface: terminology, implementation
information, and complete documentation. Applications may incorporate
them to define their own scriptability, and scripting clients such as
AppleScript and Scripting Bridge read them to determine what operations
an application supports.
man sdef
3 or 4 new projects ahead.
One of them will be CouchDB and Merb (no DataMapper, no ActiveRecord). The db schema is modeled by each user and upon criteria decisions.
All of them Git managed, as been doing for the last year.
Served by a Debian based Linux distro, coded under Debian, UNR (my lovely little netbook), and […]
Melo will be focusing on git
Once you get used to git, you won’t be needing “anything else” to maintain your code. Git is gaining more and more traction, now that bigger (distributed) projects (or parts of them) are running away from other scm’s into this one (Gnome ?, Kde, …). CVS, SVN user base is […]
Passphrases, when used the good way, present a higher level of security over passwords, but what if you are editing scripts on a remote server using a local Vim ? For every open, write, explore, you are asked for it. After a certain amount of times, it starts making no sense, and you’ll end up […]
Linus talked on Google about his source control management system, with questions from the audience. 70 precious minutes… with humour, smart ideas, good explanations on the theory of team software development, focusing on building a trust network, on performance, on centralized vs distributed systems, security, etc.
(by minute 60, this guy kicks Google Code (SVN) ass… […]
… seems that the main (or a higher) reason for Apple to release a Windows version of Safari is… income. And for that, the Google search box in to top right corner is the gateway for profit.
Windows still is the most used operating system out there, so why not take the ride ? Mozilla did […]
Started using Reinvigorate for about a month now. On a fast comparison with Google Analytics new interface, i will problably be using Reinvigorate a lot, since i don’t run Ads. Analytics is very complete, but Reinvigorate is beautifull, easy, well organized, until now very fast and… we are neighbours at (mt) MediaTemple, heh. The motto […]
Hpricot is a very interesting lib to parse HTML. I’ll post here the example, just to check on the beauty of it from time to time…
require ‘hpricot’
require ‘open-uri’
# load the RedHanded home page
doc = Hpricot(open(”http://redhanded.hobix.com/index.html”))
# change the CSS class on links
(doc/”span.entryPermalink”).set(”class”, “newLinks”)
# remove the sidebar
(doc/”#sidebar”).remove
# print the altered HTML
puts doc
The lib is evolving, being added […]
… this page is a good and simple comparison page for different MTA’s like Exim, Postfix, qmail and Sendmail.
“One scenario is to use Postfix and Exim. The logic for Postfix is that an MTA facing the Internet needs to be as secure as possible it must perform as few functions as possible. For Exim, an […]
… i finally set up the page for the download of the vimblog.vim vim-ruby script. It will allow you to manage your blog posts from *the* editor VIM, very easilly. Learn one single command and, at maximum, seven simple parameters. So go ahead and blog with vim.
It is very cool to go and buy a new computer. It sure is. But what about the old ones ? There are some companies recycling parts for these unusefull machines, but it actually is not enough. The production numbers are too high, and the used materials still too much non_environment_friendly. Manufacturers will have to […]
… this is Paul Graham’s version of why Microsoft is dead. There are some interesting parts in it. One thing he does not state, is that Microsoft never drove the internet trends. They get always late, and sometimes very late. Then, the huge ammount of monetary units and a very confortable monopolistic position in the […]
…just received a (mt) email announcing Krop. It’s a very cool && fast && simple website.
blogged with VIM
… i saw a small video on buiding a cluster. When placing the machines in the cabinet i noticed they inserted them close to the top. It is known the heat goes up, and a while ago i attended a conference where a mechanical engineer showed some heat graphs, thermal cabinet photos and presented […]
from O’Reilly MacDevCenter, an interesting interview with Nobi, with interesting facts:

“The research took about a year, and when they were done, their conclusion was that Macintosh would be the best platform, but with one condition: If Apple could keep the swap files encrypted, the bank could use the Macintosh. So the reason that Macs can […]
Well, a post about Windows… who’d say about that…
The thing is: is have a HP desktop that after a good BIOS update, got its motherboard dead. Good BIOS update. Pretty much dead motherboard. Not only happened to me. There are foruns about these HP BIOS updates for this motherboard series that gave lot’s of problems. […]
Blogging from VIM is now possible using this script. This post is being written using it. But one problem is making me loose a great ammount of time: dateCreated, meaning TMZ headache.
Wordpress XMLRPC wants a datetime timestamp for the dateCreated field. I give it an ISO8601 format as stated in XMLRPC specs.
The post is sent […]

… well the name reminds Brad Choate’s Textmate blogging bundle Brad is an excellent developer and like me, was once a Delphi (Borland great product) developer. I based this on his Textmate work. I’m coding a Vi / ViM / GViM script for a plugin that has some nice results already, exclusively for […]
… when coding switter, using lot’s of command line, vim, bash, i felt the need to blog from vim. Some readings (quite a few availlable, actually) later, i was testing Wordpress xmlrpc using MovableType (Six Apart) calls to it. Vim allows ruby scripts (when compiled with that directive) use to create new commands, just like […]
…now, switter was accepted on rubyforge.org. I’ll try to put source and some docs there (rdoc does wonders) soon. Meanwhile, and with threahds now working for continuous message post/get, it just needs some tickles on the readline method.
switter on a maximized shell window receiving public timelines
switter on a normal sized shell window receiving public timelines
Had a new idea for the switter (twitter shell client) client.
What if you had a switch that enabled you to secretly send commands to the shell via twitter service ? Now, that can be (is) dangerous. But what if you defined an hash with predefined actions, and “secret” (remember, unsafe connection) codes ?
./switter -u test […]
