New Versions of Ruby, Rails and Instant Rails

1

I’m happy that new versions of our cool development tools have been released. This includes Ruby, Rails and my favorite tool, Instant Rails.

Ruby 1.8.6 is a steady and reasonable enhancement of the 1.8 series including many bug and security fixes, standard library updates, feature enhancements and performance improvements keeping high backward compatibility with the previous release (1.8.5).

Rails 1.2.3 was released mainly to support Ruby 1.8.6.

What makes that even better is Instant Rails 1.7 that upgrades to the latest versions of Ruby, Rails and even phpMyAdmin (version 2.10.0.2). Another cool feature of the new Instant Rails is automatic RadRails configuration.

Now, just download Instant Rails 1.7 and enjoy the latest Ruby with the latest Rails.

To cache or not to cache

0

I was sitting with a couple of friends of mine, and we were discussing scalable system performance issues, we were specifically discussing mail system performance issues, when all of a sudden, one of us said “it would be better to eliminate all system caching, then we will have better performance”, Wow.. where did this come form?

Eliminating cache to boost performance? we all know that there are several system caches and buffers that stores last fetched items so that whenever someone asks for them again, the system doesn’t need to go there again to fetch them, its like an intermediate faster and smaller storage with most recent viewed blocks..

Erlang Review

0

After I got a quick look to Erlang, I started to feel a little more curios to this language, and I decided to give it a portion of my readings.

The resources of this language are limited, it is very clear that it is still in the “Early Adopter” phase. I already believe that this language can realize a very good hype very soon. Furthermore, I see it has as many advantages as the Ruby.

I won’t talk about the ordinary features which anybody can figure out by himself. What I see the most important point is “Concurrent Programming” in Erlang.
