Using `yield_self` for composable ActiveRecord relations
Ruby 2.5 introduces Object#yield_self, which can be thought of as a close cousin to Object#tap. Where tap executes a block returning the value it’s called on, yield_self yields the object its called on into the supplied block, returning the result of the block. Many have compared yield_self to Elixir’s pipe operator, |>, and while I use and enjoy the pipe operator in Elixir, I had a hard time envi
Compass の送別会 - Pepabo Tech Portal
2018 年 3 月 15 日、渋谷のはずれにある中華料理店『東亜飯店』では、 Sass の拡張フレームワークの Compass の送別会がしめやかにとりおこなわれていた。 「えー、それではですね、きょうは長年われわれのチームでいっしょに働いてきた Compass くんがついに卒業ということで、 minne のデザイナーの @shikakun から挨拶があるそうなので、よろしくお願いします」 はい、ありがとうございます。 Compass、いままでほんとうにありがとう。 Compass は、 SCSS を CSS へトランスパイルする機能だけでなく、 CSS3 で追加されたプロパティにベンダープレフィックスを付与してくれる mixin や、指定したディレクトリに画像ファイルを放り込むだけでスプライト画像も生成してくれる、とっても便利なライブラリでした。なんと最初のリリースは 2009 年で、
The “Basecamp MBA” Reading List – Signal v. Noise
The “Basecamp MBA” Reading ListA few months ago, I met a new friend at a Creative Mornings talk. She is going to take some time off at the beginning of 2018 to work through the AltMBA reading list before diving into job searching. I thought this was a great idea and it got me wondering about the kind of reading material Basecamp would suggest for people who want to build a business like ours. Of c
Chatting with Hongli Lai and Ninh Bui (Phusion) | AkitaOnRails.com
Hongli Lai and Ninh Bui, from Phusion, shaked the Rails world a few days ago. They unleashed the Holy Grail of Rails deployment: mod_rails which was received with much fanfare, and they deserved it. They finally settled the big issue that embarrassed Railers in the past. This will also relieve dozens of hosting services that were clueless on how to solve this equation. Now, those two computer scie
PostgreSQL's Foreign Data Wrapper
Have you ever needed to write a query that combined data from two PostgreSQL databases? Our client Healthify has. Since Healthify work with healthcare and store some patient information, they’re very careful not to send any personally identifiable information to third party services.

You’re not changing the world – Signal v. Noise

You’re not changing the worldI mean, in the widest possible sense, you are. Your mere existence is bound to change some of it somewhat. But that’s not what the unironic use of the phrase — WE ARE CHANGING THE WORLD — is meant to convey in
