Setting session variables in an RSpec Rails request spec

You are writing a spec with type: :request, i.e. an integration spec instead of a controller spec. Integration specs are wrappers around Rails' ActionDispatch::IntegrationTest class. I usually write controller tests using this instead of type: :controller, mainly because it exercises more of the request and response handling stack. So instead of writing something like get :index to start the request, you would write get books_path or similar.

One of the issues with using type: :request is that you lose the ability to

IScroll 5 with DOM change detection

When implementing a custom scrollbars there’s a need to detect changes in height of the element to which you are applying the scrollbars to, as the height of the scrollbars need to be adjusted based on the content’s height. We also need to take into account that the content could change and height needs to be recalculated i.e paging on queries could yield 10 results, whilst on the last page it could yield just 5 results, and these changes need to be accounted for by the scrollbar. And the same problem arises when getting content asynchronously, because whilst the content is empty on initial render it gets rendered only after successful fetch of the required data and we should calculate the scrollbar height once the content is available which is hard to determine as the operation is asynchornous.

Different libraries and plugins deal with the problem separately.

jQuery Scrollbar runs a timeout every 300ms to account for any changes in the DOM. https://github.com/gromo

Category theory jargon cheat sheet

A primer/refresher on the category theory concepts that most commonly crop up in conversations about Scala or FP. (Because it's embarassing when I forget this stuff!)

I'll be assuming Scalaz imports in code samples, and some of the code may be pseudo-Scala.

Functor

A functor is something that supports map.

リーダブルコード読書会及び要約共有会の目的

今後コードレビュー時に「これってリーダブルコードの◯◯だよね？、こう直したほうがいいよね」と引用できレビューの時間の短縮化が実現できる。
リーダブルコードに登場する特殊ワードをチームのコーディングの共通語とする。デザインパターンのカタログ的な考え。
リーダブルコードを読んでない人も内容を短時間で把握できる。
チーム全体のコードを読みやすくメンテナンスしやすくし品質をあげる。
リーダブルコード教になりチーム以外にも広める。コードの品質が悪い人にはリーダブルコードの読書を進めてみる。ひどいコードのままコーディングしてもらうよりその時間を読書の時間に割り当てることも考える(結果的に時間が還元できるなら）。
リーダブルコードに書いてあることが全てのプロジェクトに適用てきるわけではないけれでもコーディングルールを考える際の指針にすることはできる。
