Why do you prefer [Borg] over [git-lfs]/[git-annex]?

• GitHub LFS has a 2GB limit on file size. This never works with large projects like video productions.
• git-annex uses symlinks to manage annexed files. This doesn't work well on Windows.

So my conclusion at the moment is that Borg is the best backup software for mid/large-sized personal projects.

My largest Sidekiq application had a memory leak and I was able to find and fix it in just few hours spent on analyzing Ruby's heap. In this post I'll show my profiling setup.

As you might know Ruby 2.1 introduced a few great changes to ObjectSpace, so now it's much easier to find a line of code that is allocating too many objects. Here is great post explaining how it's working.

I was too lazy to set up some seeding and run it locally, so I checked that test suite passes when profiling is enabled and pushed debugging to production. Production environment also suited me better since my jobs data can't be fully random generated.

So, in order to profile your worker, add this to your Sidekiq configuration:

if ENV["PROFILE"]
