It's proven to be a GREAT way to learn the basics from the ground up while building an actual app at the same time.
1) Will the update to 3.1 be free for existing customers?
2) Would you mind to share a bit of your process of making the screencasts?
Thanks!
PS: I have the print book, the pdf, and the screencast. Love them.
The idea behind it was to have more focus on BDD than anything else out there, which is exactly what the community is all about these days.
Just like Michael's brilliant book, we go through building an application from the ground up using Rails 3.1, RSpec, Cucumber and many other gems provided by the community.
copy and paste in the following command:
/usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"
For a beginner, it makes no difference if they get burnt by a gist or by a compromised package or binary. And they can at least attempt to read https://raw.github.com/gist/323731 in plain text.
And don't forget that something like:
git clone .... sudo make install
is a huge hole for bad things to happen as well.
echo "[[ -s $HOME/.rvm/scripts/rvm ]] && . $HOME/.rvm/scripts/rvm" >> ~/.bashrc
It doesn't try to do as much, so a little less magic. The biggest thing I like is that it doesn't try to do anything with gems, which is good - I've been trying to use bundler for everything.
RVM is no more magic than rbenv, and to listen to Ruby developers (who treasure "magic") talk about it as if RVM commits some cardial sin by overriding `cd` tops out my nerd-rage-meter. Ruby, home of the monkey patchers, has no place calling out RVM for overriding `cd`.
RVM and rbenv serve similar purposes. RVM gives you gemsets as well. You may not need them today, but they're there if you do. I use Ruby for a lot of system administrative tasks. These tasks run inside cron jobs and other places where a bundle really doesn't make sense. Despite the fact that they're no longer in vogue, gemsets are still very useful.
Should you check out rbenv? Yes. But the "little less magic" is a really poor basis by which you should evaluate it as a tool.
The monkey-patching of `cd` is the main reason I'm not using RVM. I depend on `cd` to work, every time, rock solid, especially when my system is unstable. I can't risk having a dependency or bug in their `cd` script breaking my most commonly used shell command.
rbenv has demonstrated that it's not necessary to override `cd` to manage ruby versions, so why does RVM still do it?
* No need to install a second thing (ruby-build) to install rubies.
* No need to do manual things like running "rbenv rehash".
* More chatty and hand-holding (tells you dependencies you need to install for your platform, etc)
What is it about having gemsets that makes it easier for a beginner? Bundler seems to handle installing dependencies just fine.
source ~/.bashrc
If that worked add this to your .bash_profile
[ -f ~/.bashrc ] && . ~/.bashrc
echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile
