generator-webapp has support for compass out of the box. However, in order to use one of my favorite features of it — sprites and the image_url helper — you have to make some adjustments to the Gruntfile.
Let's assume you use a SASS stylesheet like this one:
@import "design/*.png"
| { | |
| "Statement": [ | |
| { | |
| "Action": [ | |
| "route53:ChangeResourceRecordSets", | |
| "route53:GetHostedZone", | |
| "route53:ListResourceRecordSets" | |
| ], | |
| "Effect": "Allow", | |
| "Resource": [ |
| jQuery.fn.selectTimeZone = function() { | |
| var $el = $(this[0]); // our element | |
| var offsetFromGMT = String(- new Date('1/1/2009').getTimezoneOffset() / 60); // using 1/1/2009 so we know DST isn't tripping us up | |
| if (offsetFromGMT[0] != '-') { | |
| offsetFromGMT = '+' + offsetFromGMT; // if it's not negative, prepend a + | |
| } | |
| if (offsetFromGMT.length < 3) { | |
| offsetFromGMT = offsetFromGMT.substr(0, 1) + '0' + offsetFromGMT.substr(1); // add a leading zero if we need it | |
| } | |
| var regEx = new RegExp(offsetFromGMT); // create a RegExp object with our pattern |
| # Takes a table name, and an array of hashes where keys are column names and values are values. | |
| # Expects hashes to all contain the same keys. | |
| def bulk_insert(table, rows) | |
| columns = rows.first.keys | |
| to_insert = rows.map do |d| | |
| vals = columns.map {|k| d[k] } | |
| ActiveRecord::Base.send(:replace_bind_variables, "(#{vals.length.times.collect {'?'}.join(',')})", vals) | |
| end |
| def valid_msp_number(msp_number) | |
| weights = [0, 2, 4, 8, 5, 10, 9, 7, 3, 0] | |
| total = 0 | |
| weights.to_enum.with_index(1).each do |weight, i| | |
| total = total + msp_number[i-1].to_i * weight.to_i | |
| end | |
| a = total / 11 | |
| b = a * 11 | |
| c = total - b | |
| result = 11 - c |
Update: The original post on Netmag has been updated since this was written.
I tweeted earlier that this should be retracted. Generally, these performance-related articles are essentially little more than linkbait -- there are perhaps an infinite number of things you should do to improve a page's performance before worrying about the purported perf hit of multiplication vs. division -- but this post went further than most in this genre: it offered patently inaccurate and misleading advice.
Here are a few examples, assembled by some people who actually know what they're talking about (largely Rick Waldron and Ben Alman, with some help from myself and several others from the place that shall be unnamed).
| class ActiveRecord::Base | |
| mattr_accessor :shared_connection | |
| @@shared_connection = nil | |
| def self.connection | |
| @@shared_connection || ConnectionPool::Wrapper.new(:size => 1) { retrieve_connection } | |
| end | |
| end | |
| ActiveRecord::Base.shared_connection = ActiveRecord::Base.connection |
