Compare to four years ago. New: git, php, mate, rsync, cat, make. Climbers: ls. Same: cd, ssh. Fallers: vi. Old: u, ruby, svn, td, mysql, gd.

• If you cat a file without a trailing newline your prompt may appear at the end of the output instead of flush left.
• Some C++ compilers complain when there is no trailing newline.
• Each line in the file ends in a newline.
• wc -l reports an incorrect result if it is missing
• More reasons

Against

• git considers a trailing newline a whitespace error.
• Trailing whitespace is easily lost when, for example, exchanging patches via email.
• A newline after a closing “?>” in PHP can cause problems with header() (although closing tags are no longer required in PHP).
• It uses one more byte.

Edit: Better:

#!/bin/env ruby

BAZEL_HOME = '/Users/bakert/bazel'
STANDARD_PATH = '/Users/bakert/Desktop/BazelCodingStandard'
VERBOSE = false

def main
  exclude_patterns = [ /XG_MessageCatalog_/, /\/lib\/deps\//, /\/lib\/ext\// ]
  files = Dir.glob("#{BAZEL_HOME}/src/main/webapp/**/*").reject do |f|
    exclude_patterns.any? { |p| f.match(p) } \
      || ! File.file?(f) \
      || File.extname(f) != '.php'
  end
  files.each do |f|
    puts f if VERBOSE
    print %x[phpcs -d memory_limit=1024M -n -s --standard=#{STANDARD_PATH} #{f}]
  end
end

main

I like it.

1. iMovie, Preferences
2. Check “Show Advanced Tools”
3. File, Project Properties, Timing
4. Set Initial Photo Placement to “Crop”
5. Drag the PNG with transparency to the point you want the overlay to appear in the timeline
6. From the resulting pop-up menu choose “Overlay” (for full screen) or “Picture in Picture” (for part-of-screen)
7. Adjust the size and duration of your overlay

$ a2enmod proxy_http
$ a2enmod proxy

Configured under sites-available like so:

$ cat /etc/apache2/sites-available/movies
<VirtualHost *:80>
    ServerName actualfqdnofhost.bluebones.net
    ServerAlias movies.bluebones.net
    ProxyPass / http://127.0.0.1:3000/
    <Proxy *>
	Allow from all
    </Proxy>
</VirtualHost>

(This assumes that your app listens on port 3000 when running.)

Then to ensure it gets restarted when the machine does I created the following file as /etc/init/movies.conf

$ cat /etc/init/movies.conf
description "movies.bluebones.net on node.js"
author "bakert"

start on startup
stop on shutdown

script
  export MOVIES_ROOT=/srv/movies
  export EXPRESS_ROOT=$MOVIES_ROOT/src/express
  cd $EXPRESS_ROOT && exec sudo -u www-data NODE_PATH=$NODE_PATH:/opt/local/node/lib/node_modules/ EXPRESS_ENV=production /opt/local/node/bin/node $EXPRESS_ROOT/app.js 2>&1 >>$MOVIES_ROOT/logs/node.log
end script

Which also lets me stop and start my app with:

$ start movies
$ stop movies

“Show Original” in gmail used to say:

Received-SPF: neutral (google.com: 74.54.101.112 is neither permitted nor denied by domain of bakert+fantasyfootball@gmail.com) client-ip=74.54.101.112;
Authentication-Results: mx.google.com; spf=neutral (google.com: 74.54.101.112 is neither permitted nor denied by domain of bakert+fantasyfootball@gmail.com) smtp.mail=bakert+fantasyfootball@gmail.com

Now it says:

Received-SPF: pass (google.com: domain of admin+2@ff.bluebones.net designates 178.79.178.155 as permitted sender) client-ip=178.79.178.155;
Authentication-Results: mx.google.com; spf=pass (google.com: domain of admin+2@ff.bluebones.net designates 178.79.178.155 as permitted sender) smtp.mail=admin+2@ff.bluebones.net

This means Gmail is less likely to mark email sent by my web app as spam, thanks to the SPF record I have set up.

An SPF record is implemented as a DNS TXT (as opposed to A, CNAME, etc.) record with no “name” and a value something like this:

v=spf1 a mx include:_spf.google.com ~all

Let’s break that down …

v=spf1 – this indicates that the record is an SPF v1 record.

A – this indicates that any IP address in an A record for this network is allowed to send email for this domain.

MX – this indicates that any IP address in an MX record for this network is allowed to send email for this domain.

include:_spf.google.com – this indicates that _spf.google.com is allowed to send email for this domain.

~all – this indicates that _spf.google.com is allowed to send email for this domain.

All parts of the record except v=spf1 are optional and can take a prefix of -, + or ~. If there is no prefix + is assumed. + means allowed, – means not allowed and ~ means might be allowed. all is the catch-all for anything not explicitly called out by the rule.

You might be interested in a more detailed guide to SPF record syntax.

On the nameserver for example.com:

somesubdomain			NS	ns1.otherprovider.net
somesubdomain			NS	ns2.otherprovider.net
somesubdomain			NS	ns3.otherprovider.net
somesubdomain			NS	ns4.otherprovider.net

On the otherprovider.net nameserver for somesubdomain.example.com you just need a “normal” A record (+CNAME/MX/whatever):

somesubdomain			A	178.79.178.155

I have this setup working with everydns.net providing most of my DNS but linode providing DNS for the sites I have moved off my old providers and on to linode.

The previously wonderful everydns that served me well for many years (for nothing!) has been bought up and is going paid in less than 90 days so I’m taking this opportunity to move things around.

$ sudo npm install nodemon
$ nodemon app.js

movies.jade in the views directory:

div(id='movies')
  - each movie in movies
    !=partial('movie', movie)

where movie.jade is also in the views directory.
