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"]

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

Safari's date-picker is the cause of 1/3 of our customer support issues

...and obviously we're building a workaround. But I'm absolutely flabbergasted that a standard <input type="date"> HTML field, in a standard browser, from a company that bases its reputation good design, could be so dreadful.

The context

I'm the developer for a startup that sells a genetic test to recommend medications for high blood pressure. For medical reasons we need to know our customers' birth date. Most of our customers are in their 60s or older. We've found that many of them use iPads or iPhones. And they're the ones who complain to our customer support that our site is unusable.
