Re: camping app on elastic beanstalk
If you run the migrations it should create the database for you.

Is the app.db file in your project directory on the instance? If not, can you try copying it from the local environment to see if it fixes the problem? Also, are you sure sqlite3 gem has built native extensions properly?

Camping without markaby.
How can I use something other than markaby for my views? My understanding is that markaby is very slow. Thanks. ___ Camping-list mailing list Camping-list@rubyforge.org http://rubyforge.org/mailman/listinfo/camping-list

Re: Benchmarked
ASW would be interesting as that's a very common use case for us and I am sure many other people. On Tue, Nov 19, 2013 at 12:44 PM, Koaps Freeman koapsfree...@gmail.comwrote: I was initially playing with Erlang, talk about good times, and I just got frustrated trying to do things I can do easily in Ruby and decided to fall back to Camping which I like a lot. Then I came across Celluloid (http://celluloid.io/) and with it on JRuby you can pretty much take full advantage of all your CPU cores. Plus it does the 'let it fail' actor model, so when your Camping app crashes, it just restarts the actor again. This can make for a really robust webapp with all the benefits of running within a JVM. I then saw Reel-Rack which made running Camping easier, but I had the question of, how good would the performance be with all the overhead of JVM - JRuby - Celluloid::IO - Reel - Reel-Rack - Camping. That's when I started putting together the benchmark project just to see how that setup would look against a MRI version of my webapps. The simple tests don't really do it much justice, I'm starting to play with DCell and ZeroMQ, so I might try to come up with some examples where JRuby can use all the cores and see how MRI does with the same code. I also tried to play with Rubinis but ran into install issues with some Gems so I decided to stick with JRuby. I'm also on SmartOS in a Zone and KVM for Linux, so the tests might be completely different on a pure linux install on the same hardware, for better or worse. Would be interesting to see but I'm not going to rebuild my server to find out, maybe I'll try it in AWS or something.

Re: Camping Blog with Sequel, Thin and Rake
Thanks for posting this. It's good to have a non trivial one file app to learn from.

I mainly did this because I'm testing using Camping on JRuby and Celluloid's Reel-Rack and since native extensions are problematic on current JRuby, I needed an easy alternative to pg gem and Sequel JDBC:Postgres isn't bad, though I could have used JDBC from AR.

Re: Would like some hints on best ways to search for camping questions.
Thanks. I might try the IRC but I am in NZ (currently in AU) so my time zones tend to be unfriendly to most IRC channels. My questions are about non trivial apps. What do I do about migrations? What if I don't want to use markaby? what's a good strateg for breaking your app up into different files?.

A question about the ecosystem.
I am a long time rails developer looking for a new framework which is leaner and less complex than rails. Camping appeals to me for a lot of reasons but I am curious about how a moderately conplex app would look like in camping. In rails my Gemfile is full of third party libraries and I am wondering if they will all (or most) work with camping. My guess is that they won't and I am worried that I will have to code up all kinds of functionality I take for granted in the rails world. Maybe that's a good thing but I wanted to ask you guys about your experience in taking advantage of other people's work.
