A Deep Dive into Memory Leaks in Ruby
The memory_profiler gem offers a very simple API and a detailed (albeit a little overwhelming) allocated and retained memory report — that includes the classes of objects that are allocated, their size, and where they were allocated. It's straightforward to add to our leaky program.

Ok y’all. How can we get this kind of real-time memory profiling in Ruby? Does it already exist? Is anyone working on this?

Advanced ActiveRecord Querying - With Benchmarks!
We don't need to rely upon a priori reasoning only, we can use memory_profiles and benchmark_ips to compare the memory consumption and iterations per second of each solution.

Is there a more efficient way to do these permutation calculations?
Either https://github.com/tmm1/stackprof for cpu or https://github.com/SamSaffron/memory_profiler for memory. In practice profiling and removing allocations also gives a large perf boost.

Reduce memory consumption with a custom ActiveRecord attribute
Our project has one endpoint which gets called quite often. So, I profiled it with memory profiler and saw a line pointing to hstore.rb.
