Making Thumbnails with RMagick

Timothy H. noticed that a lot of people were using RMagick to
thumbnails of JPEG images, so he benchmarked four different resize

The overall winner was the `thumbnail’ method. That’s easy to
remember :slight_smile:

Kevin B. asked how to connect to PostgreSQL through SSL, and Dick
Davies replied, saying that if he uses the ruby-postgres library
wraps the C client library), then this is handled “transparently” as

certificate/key files in the ~/.postgresql directory.

Kevin later managed to get this working via psql, but the Ruby code
giving the error #<PGError: SSL error: sslv3 alert handshake

wxruby 2

baalbek wondered about the status of wxruby2, and Alex F. said
close to being ready for beta release, but there are some important
that need fixing.

| There is a good group of C++ developers involved who made a lot of
| progress over last summer, but they’ve all been short of time in
| last few months, so been a lull in development.
| It’s usable enough for playing around, and has some nice new
| beyond 0.6.0 - on top of all the native look’n’feel niceness of Wx
| generally - such as good support for OS X (inc aqua-look), Unicode,
| widgets, and better exposing of Wx class hierarchies. Unlike 0.6.0
| release from the old series, I wouldn’t say it’s stable enough for
| production code.
