It’s been 3 weeks since we launched the new eBox Platform homepage, and I wanted to share the different steps through the redesign.
Do you like the new design?
Do you like any of the previous steps better?
Do you have any suggestions?
Since I upgraded to Snow Leopard I’ve been missing readline whe using irb. As I discovered in this article, this is due to apple’s ruby linking to libedit instead of libreadline. I didn’t have that problem before the upgrade since I had compiled ruby myself.
This time, I was looking for another solution. I could have compiled ruby with readline support, but then probably I’d had to reinstall some gems too. So I present you the quick way to fix your readline
mkdir -p /tmp/rlruby
cd /tmp/rlruby
sudo -s
curl -O ftp://ftp.cwru.edu/pub/bash/readline-6.0.tar.gz
tar xvf readline-6.0.tar.gz
cd readline-6.0
./configure && make && make install
cd ..
To keep the complications to a minimum, I downloaded ruby from apple (check 10.6.2 open source, or other releases). The current patchlevel is ruby-75 so fetch that one:
curl -O http://www.opensource.apple.com/tarballs/ruby/ruby-75.tar.gz
tar xvf ruby-75.tar.gz
cd ruby-75
We don’t need to build all ruby, just the readline extension
cd ruby/ext/readline/
ruby extconf.rb
make
At this point, you’ll probably get the following error:
readline.c: In function ‘username_completion_proc_call’:
readline.c:730: error: ‘username_completion_function’ undeclared (first use in this function)
readline.c:730: error: (Each undeclared identifier is reported only once
readline.c:730: error: for each function it appears in.)

make: *** [readline.o] Error 1
We need to tell gcc that our readline is in /usr/local
make readline.o CFLAGS='-I/usr/local/include -DHAVE_RL_USERNAME_COMPLETION_FUNCTION'
cc -arch i386 -arch x86_64 -pipe -bundle -undefined dynamic_lookup -o readline.bundle readline.o -L/usr/local/lib -L/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib -L. -arch i386 -arch x86_64 -lruby -lreadline -lncurses -lpthread -ldl
To be sure we are using the real readline run otool and make sure libedit doesn’t appear on the results:
$ otool -L readline.bundle
readline.bundle:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/libruby.1.dylib (compatibility version 1.8.0, current version 1.8.7)
/usr/lib/libncurses.5.4.dylib (compatibility version 5.4.0, current version 5.4.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.0)
cd /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/lib/ruby/1.8/universal-darwin10.0/
mv readline.bundle readline.bundle.libedit
cp /tmp/rlruby/ruby-75/ruby/ext/readline/readline.bundle readline.bundle
Now launch irb and check if all your favorite shortcuts are in place
I sure am. After a proper installation/configuration, the most important factor is to always stay updated to the last version. I’m managing at this time 8 or more blogs/websites running different versions of WordPress and it’s hard to keep them up to date.
Automatic upgrades help, although they still terrify me after the 2.8 crash.
The problem is, some of these blogs are set up for friends or old projects, and I forgot to frequently check if they are using the latest version. Most of the times, they become crammed with spam, and eventually trigger google’s malware detectors. Most of the times I notice the hack because of firefox malware warning.
So I started a side project to help me keep track of all those blogs and their versions, and it’s seems is close to see the light. This is how it looks right now:
I will need testing, so if you want to participate in the beta, fill the signup form, and I’ll send some invitations.
Also, I’m looking for a nice name for the thing. If you have a good idea, put it in the ‘Proposed name’ field on the signup form. The winner(*) will get the first beta invitation and free full access to the product for 1 year after it launches. Make sure a .com domain is available for the name you propose or it won’t have many chances.
(*) There will be only 1 winner: the first person to propose the chosen product name. Simple rules, but… without rules we are nothing but savages.
I need help with this. I had a dream… Well, not so much as a dream, maybe a “It’d be cool to…”
I thought it’d be nice to discover new photos on flickr using your favorite photos and the people who also favorited those photos, and the favorite photos of those who also favorited my pictures. Still with me?
It’s actually a quite simple code (about 500 lines, check it on github: discovr), but it’s terribly slow. Some possible reasons:
The simplified algorithm goes like this.
# method from class User
def similar_pictures
similar = {}
favorites.each do |favorite|
favorite.favorited_by.each do |user|
user.favorites.each do |v|
similar[k] ||= {:weight => 0, :picture => v[:picture]}
similar[k][:weight] += 1
end
end
end
similar.values.sort {|a,b| b[:weight] a[:weight]}.select {|v| v[:weight] > 1}
end
So I’ve created a github repository and uploaded the code: discovr at github. Feel free to clone, test and improve
