Note that this validation runs both after the file is uploaded and after CarrierWave has processed the image. If your base uploader includes a filter to resize the image then the validation will be run against the resized image, not the original one that was uploaded. If this causes a problem for you, then you should avoid using a resizing filter on the base uploader and put any specific size requirements in a version instead.

So instead of this:

require 'carrierwave/processing/mini_magick'

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

Proposal for Improving Mass Assignment

For a while, I have felt that the following is the correct way to improve the mass assignment problem without increasing the burden on new users. Now that the problem with the Rails default has been brought up again, it's a good time to revisit it.

Sign Allowed Fields

When creating a form with form_for, include a signed token including all of the fields that were created at form creation time. Only these fields are allowed.

To allow new known fields to be added via JS, we could add:

module Tire
  module Disable
    module ClassMethods
      def mock_es_response_doc
        @mock_es_response_doc ||=
          '{"took": 1,"timed_out": false,"_shards": {"total": 5,"successful": 5,"failed": 0},"hits": {"total": 0,"max_score": null,"hits": []}}'
      end

      def enable! &blk
        old_enabled = @tire_enabled || false

class ActionDispatch::Routing::Mapper
  def draw(routes_name)
    instance_eval(File.read(Rails.root.join("config/routes/#{routes_name}.rb")))

  draw :api
  draw :account
  draw :session

# Floyd-Warshall Algorithm
## Introduction:
Finds Shortest Path (or longest path) among all pairs of nodes in a graph.
Complexity: O(|n|³)


## How does it work?
- There can be more than one route between two nodes.
- The number of nodes in the route isn’t important (Path 4 has 4 nodes but is shorter than Path 2, which has 3 nodes)
- There can be more than one path of minimal length

1. Download docker-compose.yml to dir named sentry
2. Change SENTRY_SECRET_KEY to random 32 char string
3. Run docker-compose up -d
4. Run docker-compose exec sentry sentry upgrade to setup database and create admin user
5. (Optional) Run docker-compose exec sentry pip install sentry-slack if you want slack plugin, it can be done later
6. Run docker-compose restart sentry
7. Sentry is now running on public port 9000
