AdequateRecord Pro™: Like ActiveRecord, but more adequate | Tenderlove Making
TL;DR: AdequateRecord is a set of patches that adds cache stuff to make ActiveRecord 2x faster I’ve been working on speeding up Active Record, and I’d like to share what I’ve been working on! First, here is a graph: This graph shows the number of times you can call Model.find(id) and Model.find_by_name(name) per second on each stable branch of Rails. Since it is “iterations per second”, a higher v
Rails 4 and your Gemfile | Tenderlove Making
TL;DR This is your periodic reminder to specify dependency versions in your Gemfile I started updating one of our larger projects at work to use edge Rails. This project uses devise, and the Gemfile declares the dependency like this: The latest version of devise correctly declares its dependency on Railties on ~> 3.1: However, Devise version 1.5.3 does not declare a specific dependency on Rails (o
Removing config.threadsafe! | Tenderlove Making
TL;DR: config.threadsafe! can be removed, but for Rails 4.0 we should just enable it by default. A while back a ticket was filed on the Rails tracker to turn on config.threadsafe! mode by default in production. Unfortunately, this change was met with some resistance. Rather than make resistance to change a negative thing, I would like to make it a positive thing by talking about exactly what confi
Is it live? | Tenderlove Making
TL;DR Rails 4.0 will allow you to stream arbitrary data at arbitrary intervals with Live Streaming. HAPPY MONDAY EVERYONE! Besides enabling multi-threading by default, one of the things I really wanted for Rails 4.0 is the ability to stream data to the client. I want the ability to treat the response object as an I/O object, and have the data I write immediately available to the client. Essentiall
Rack API is awkward – Tender Lovemaking
TL;DR: Rack API is poor when you consider streaming response bodies. ZOMG!!!! HAPPY THURSDAY!!!! Maybe I shouldn’t be so excited now. I want to talk about stuff I’ve been working on in Rails 3.1, and problems I’m encountering today. I want to use this blllurrrggghhh blog post to talk through through the problems I’ve been having, and to share the pain with others. Pie is delicious! One feature tha
Tender Lovemaking » Blog Archive » Event based JSON and YAML parsing
Let’s use Ruby 1.9.2 and Psych to build an event based twitter stream parser. Psych is a YAML parser that I wrote and is in the standard library in 1.9.2. Eventually, it will replace the current YAML parser, but we can still use it today! But you said YAML and JSON! wtf? I know! In the YAML 1.2 spec, JSON is a subset of YAML. Psych supports YAML 1.1 right now, so *much* (but not all) JSON is suppo
Tender Lovemaking » Blog Archive » RDoc on your iPad
Oh snap! I haven’t posted here in a long time. My day job and my night jobs have been keeping me too busy! Hopefully I’ll have more time to blog in the future. I have a bunch of ideas, I just need to find the time to write! Anyway, let’s talk RDoc, iPad, and epub! I like documentation. I especially like consuming documentation. I thought it would be neat if I could read documentation on my iPad. A
Tenderlove Making - Testing JavaScript Outside the Browser
The other day at LA RubyConf during the Johnson presentation, I showed a few slides which I don’t think were given the time that they deserve. Not that we didn’t have enough time, I just don’t think I made as big a deal about them as I should have. Those particular slides demonstrated HTML Document Object manipulation executed in JavaScript outside any web browser. Those particular slides, and tha
Identifying unknown music with Ruby - Tender Lovemaking
Ben Bleything inspired me (or rather distracted me from my yak shaving) to get my music library cleaned up and remove duplicates. Unfortunately my duplicates don't necessarily have ID3 tags, and they may be in different formats, so I wrote a gem called "earworm" which will identify unknown music. First I'll give you a code sample, then explain how to get earworm working, and finally explain how ea
