What Hacker News says
5 sourcesI've started sticking testimonials in my Readme's. https://github.com/n8/multi_fetch_fragments and https://github.com/n8/cohort_me
It's hard to split test these if they are working, but these two projects have gotten a lot more visibility than other open source stuff I've put out.
Over an over again I see social proof have profound effects on getting people's attention.
In How to Spread The Word About Your CodeI've started treating the README's to my open source projects almost like landing pages for products. So I now do a couple things I might do for a product page: lead with pain and testimonials.
I'll open with something that describes the pain someone might be going through to catch their interest with the project. And I'll also make sure to include a testimonial or two from folks using the project. Here are a couple examples:
https://github.com/n8/multi_fetch_fragments
https://github.com/n8/cohort_me
I don't have enough data to scientifically judge the results. But since I've started doing this I do know my most recent three open source projects have gotten a lot more traction than previous projects.
In How To Make Your Open Source Project Really AwesomeSure! I should note, too, I was already caching each individual item, then pulling in each cache one-by-one. The above improvements were only due to your gem.
Also, I submitted a pull request [1] to add support for cache options, like "expires_in: 3.days".
That's the only thing I could think to add. This is one of those magic libraries that you're just like, man, did that really happen? Everybody should use this.

In Faster Rails partial rendering and caching. 78% improvement of test applicationThanks for answering that. Yep, there's a bit here:
https://github.com/n8/multi_fetch_fragments/blob/master/lib/...
@collection.each do |item|
key = @options[:cache].is_a?(Proc) ? @options[:cache].call(item) : item
expanded_key = ActiveSupport::Cache.expand_cache_key(key)
keys_to_collection_map[expanded_key] = item
end
Where I use ActiveSupport::Cache.expand_cache_key to create a key based on the item or the Proc passed in. And expand_cache_key does the work of coming up with the proper key. And activerecord objects have a default cache_key implemented that uses an updated_at timestamp if it's available:
