OS X Yosemite Messages database merger

Early betas of OS X Yosemite had a bug where the library of old messages wasn't migrated. Instead a new library was created and all old messages were gone.

The bug has been fixed, but if you were affected, you still have two separate libraries. This script merged them for me. Use it at your own risk! You might end up worse than before. Backup everything beforehand. Twice.

This is what your ~/Library/Messages folder will look like if you're affected:

chat.db

I had some trouble getting Ember-CLI and Ember-Data working with my existing HTTP API. These are the things I had to do to get it working:

Use `ActiveModelSerializer` by default

My API returns underscored_keys, not camelizedKeys. It's not exactly the standard ActiveModel, but it's quite similar. I started by defining a default (application) serializer that's a simple subclass of DS.ActiveModelSerializer:

// app/serializers/application.js
import DS from "ember-data";

ffmpeg

Converting Audio into Different Formats / Sample Rates

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

You can get the list of installed codecs with:

Get Git log in JSON format

git log --pretty=format:'{%n  "commit": "%H",%n  "abbreviated_commit": "%h",%n  "tree": "%T",%n  "abbreviated_tree": "%t",%n  "parent": "%P",%n  "abbreviated_parent": "%p",%n  "refs": "%D",%n  "encoding": "%e",%n  "subject": "%s",%n  "sanitized_subject_line": "%f",%n  "body": "%b",%n  "commit_notes": "%N",%n  "verification_flag": "%G?",%n  "signer": "%GS",%n  "signer_key": "%GK",%n  "author": {%n    "name": "%aN",%n    "email": "%aE",%n    "date": "%aD"%n  },%n  "commiter": {%n    "name": "%cN",%n    "email": "%cE",%n    "date": "%cD"%n  }%n},'

The only information that aren't fetched are:

%B: raw body (unwrapped subject and body)
%GG: raw verification message from GPG for a signed commit

Subdomaining Localhost with Rails 5

I've been following this blog post on how to set up an api-only Rails 5 application. One of the sections talks about creating a subdomain for your api

Rails.application.routes.draw do
  constraints subdomain: "api" do
    scope module: "api" do

Version: ^0.2.0-beta.5

How can I check the serialized version of a model?

server.get('api/employee's, function(schema, request) {
  employee = schema.employee.find(1);
  this.serializerOrRegistry.serialize(employee, request);

  return foo;
});
