iPhone's Missing Feature

Posted by Fri, 04 Apr 2008 00:17:00 GMT

I love my iPhone. There… I said it.

There is one problem with it (and I don’t blame Apple for it). Multimedia Messaging is pretty much non-existent with non-iPhone friends & family. My family continues to send me pictures/videos via text message… because they can with their other friends and family. I find myself looking at the following message quite often.

Then I go to AT&T’s AMAZING site…

...and I get a broken image.

Great work AT&T! Apple… this is tainting my experience with the iPhone. Make them fix it!

Installing Ruby on Rails and PostgreSQL on OS X, Third Edition

Posted by Tue, 22 Jan 2008 17:55:00 GMT

3 comments Latest by Scof Fri, 05 Feb 2010 18:03:22 GMT

Over the past few years, I’ve helped you walk through the process of getting Ruby on Rails up and running on Mac OS X. The last version has been getting a lot of comments related to issues with the new Apple Leopard, so I’m going this post will expand on previous installation guides with what’s working for me as of January 2008.

The following guide is how our development team at Planet Argon prefers to setup our development workstations

WARNING: This post contains some outdated instructions. Please read Installing Ruby on Rails, Passenger, PostgreSQL, MySQL, Oh My Zsh on Snow Leopard, Fourth Edition , which is focused on Installing Ruby on Rails on Snow Leopard.

During this installation, we’ll have what we feel is the optimal development stack for building Ruby on Rails applications with our favorite database server, PostgreSQL.

Ready? Let’s get started…

Phase One

During this initial phase, we’re going to install the underlying dependencies that we’ll be building off of.

XCode 3.0

The first thing that you’ll need to install to get far with this process is XCode tools, which is distributed by Apple. You can find this on the DVD that your Leopard installer is on. You can also download the latest version from Apple’s developer site.

The current version (3.0) is 1.1 GB.. so the download time will vary depending on your connection speed. I would encourage you to drink some tea and/or read a book

Once you finish the installation, you can move forward. The rest of these installation will not work until XCode is installed. :-)

MacPorts

In this next step, we’ll install MacPorts (formerly known as DarwinPorts). The MacPorts web site describes itself as, “an open-source community initiative to design an easy-to-use system for compiling, installing, and upgrading either command-line, X11 or Aqua based open-source software on the Mac OS X operating system.”

This tool is about to become one of the most important tools on your operating system as it’ll be used time and time again to maintain your libraries and many of the Unix tools that you’ll be using. If you’re from the Linux or BSD world, you are likely familiar with similar tools… such as: apt-get, port, and yum.

First, you’ll want to download MacPorts and install the “dmg” disk file for Leopard at the following link.

Once downloaded, you’ll want to run the installer and install it on your workstation.

Install MacPorts-1.6.0

Work you way through the installer until successfully installed.

Install MacPorts-1.6.0

Once this finishes, you can open up your favorite terminal application and run the following to test that it installed properly.

In my case, I’m now using Terminal.app.

Issue the command: /opt/local/bin/port version

_opt_local_bin_port version

If it responds with a version number like mine did in the screenshot above, we’re moving along nicely.

Environment Paths

When we install MacPorts, the command to install/update ports installed to /opt/local/bin. We had to provide the entire path as this isn’t currently showing up in the default $PATH on Leopard. Let’s quickly remedy this by modifying the file /etc/profile.

If you have Textmate installed, you can run the following from your terminal: mate /etc/profile

Add the following line to the bottom of /etc/profile.

export PATH=/opt/local/bin:/opt/local/sbin:$PATH
profile

You can use your favorite editor to update this file. Once you save it, you’ll want to restart your terminal application (or open a new tab) to create a new session. When your new terminal opens, run the following to verify that port is showing up in your $PATH.

which port

You should see /opt/local/bin/port show up as the result of this command.

which port

Great, let’s continue to move forward.

Hiding Apple’s Ruby, Gems, and Rails

Before we install Ruby from MacPorts, we’ll go ahead and hide Apple’s Ruby installations.


    :~ robbyrussell$ sudo su -
    Password:
    :~ root# mv /usr/bin/ruby /usr/bin/ruby.orig
    :~ root# mv /usr/bin/gem /usr/bin/gem.orig
    :~ root# mv /usr/bin/rails /usr/bin/rails.orig
    :~ root# logout    
hiding apples ruby

If you ever decide to remove MacPorts, you can just rename ruby.orig back to ruby and you’re back where you started… and the same for the others listed.

Phase Two

During this next phase, we’re going to install Ruby and Ruby on Rails.

Installing Ruby via MacPorts

Now that we have MacPorts up and running, we’re going to use it for the first time. We’ll start by using it to install Ruby and the Rubygems package.

$ sudo port install ruby rb-rubygems

Okay, this will take a little while. I’d suggest that you step out to get some fresh air.

How was it outside? What’s the weather like there today? It’s currently 2:30am PST so it’s dark and an 28F outside so I didn’t stay outside very long.

If you’re still waiting for it to install, perhaps you could watch the following video. I might encourage you to check out more of Jam, which was recommended a few years ago to me by James Adam at Canada on Rails.

Be warned… it’s a strange show, but I find strange things like this funny. :-)

If you prefer something a bit more lighthearted…

Okay… when Ruby finishes installing, you’ll want to test that you can run it.

$ ruby -v

Great, let’s move forward!

Installing Ruby on Rails via RubyGems

We’re now going to install the libraries that make up Ruby on Rails via RubyGems.

$ sudo gem install --include-dependencies rails

This will install the following gems.

  • rails-2.0.2
  • rake-0.8.1
  • activesupport-2.0.2
  • activerecord-2.0.2
  • actionpack-2.0.2
  • actionmailer-2.0.2
  • activeresource-2.0.2

Excellent, let’s move forward…

If you haven’t already purchased it, I recommend that you take a look at The Rails Way (Addison-Wesley Professional Ruby Series) by Obie Fernandez.

Installing Mongrel via RubyGems

Let’s now install Mongrel, which is an excellent Ruby-based web server for Ruby on Rails applications. We use it in development and production at Planet Argon and it’s also what we recommend to our hosting customers.

$ sudo gem install --include-dependencies mongrel mongrel_cluster
  • Note: Be sure to select the proper platform for mongrel. (hint: OS X is NOT mswin32)
My terminal output:

Select which gem to install for your platform (i686-darwin9.1.0)
 1. mongrel 1.1.3 (java)
 2. mongrel 1.1.3 (i386-mswin32)
 3. mongrel 1.1.3 (ruby)
 4. mongrel 1.1.2 (ruby)

Great, you have almost all of the essentials.. except a database.

Phase Three

In this phase, we’re going to get our database server, PostgreSQL, installed and the libraries that Ruby needs to communicate with it.

Installing PosgreSQL with MacPorts

At Planet Argon, we design and develop our applications on top of PostgreSQL. I’ve been advocating the adoption of this awesome open source database in the Rails community for quite some time now.

The current version available of PostgreSQL via MacPorts is 8.3, which is what we’ll now install with the port command.

$ sudo port install postgresql83 postgresql83-server

This will download and install the necessary libraries to run PostgreSQL server and the client utilities.

Configuring PostgreSQL

When PostgreSQL is finished installing, it’ll tell you to run the following commands to create a new database instance.


 sudo mkdir -p /opt/local/var/db/postgresql83/defaultdb
 sudo chown postgres:postgres /opt/local/var/db/postgresql83/defaultdb
 sudo su postgres -c '/opt/local/lib/postgresql83/bin/initdb -D /opt/local/var/db/postgresql83/defaultdb'

Adding PostgreSQL to launchd

If you’d like to have PostgreSQL automatically startup after a system restart, you can load it into launchd, which comes with OS X. By running the following command, PostgreSQL will startup automatically on the next system restart.

sudo launchctl load -w /Library/LaunchDaemons/org.macports.postgresql83-server.plist

Adding PostgreSQL to your $PATH

For some reason, the MacPort for PostgreSQL doesn’t get the programs in your path automatically, so we’ll it now.

mate /etc/profile

Modify the PATH that we changed earlier to include /opt/local/lib/postgresql83/bin@.

export PATH=/opt/local/bin:/opt/local/sbin:/opt/local/lib/postgresql83/bin:$PATH

Save the file and then open a new terminal. To test this, you should get the following output when you run which psql.


  $ which psql
  /opt/local/lib/postgresql83/bin/psql    

Creating a new PostgreSQL user

When I’m working on Rails applications in my development environment, I really don’t want to have to specify a username and password in every config/database.yml file for each of our ongoing client projects. When PostgreSQL was installed, it created a superuser named postgres, which is great, but I’d like one that matches my system username, so that I’m not prompted at all for a username or password to connect to PostgreSQL.

To do this, we’ll use the createuser command, which comes with PostgreSQL. As you can see, I’m creating a new user with superuser privileges (and will hopefully be the last time I have to do a -U postgres).


  $ createuser --superuser robbyrussell -U postgres
  CREATE ROLE    
Let’s take a quick moment to test this out.

  # create a new database
  $ createdb my_test_db
  CREATE DATABASE

  # drop the database
  $ dropdb my_test_db
  DROP DATABASE

Great, everything looks good here.

We now have a running installation of PostgreSQL with a new user account. All we need to do now is install the appropriate RubyGem to allow our Ruby applications to connect to it.

Installing PostgreSQL Libraries for Ruby

You can install postgres gem by running the following command.

$  sudo gem install --include-dependencies postgres

Great. We’ve now built a professional development environment for working with Ruby on Rails. Can you feel the excitement? :-)

Closing Thoughts

Like the previous versions, I hope that a few people find this useful. I didn’t have to make a lot of changes from the second edition, but there were enough to warrant a new post. I’ve been setting up my workstation like this for about three years now and I’m looking forward to seeing how a fresh install on Leopard works out for me.

If you have any problems, feel free to ask a question in the comments below.

Skitch... my favorite desktop application of 2007?

Posted by Tue, 20 Nov 2007 19:04:00 GMT

It just occurred to me that my first Skitch was on July 7th, 2007. 7/7/7. I’ve been meaning to post an article about how Skitch has changed the way our team approaches reporting bugs and communicating ideas visually.

First of all, the Skitch web site advertises it (see video) as a fun tool for playing with photos and sharing stuff with friends/family. While this is true, I think their bigger market could be those of us who work in the web design and development community. It took a less than a week for Skitch to become a tool that I rely on the most during my day to day work and since it keeps surprising me that people aren’t using it and/or haven’t heard about it… I thought that I’d share how we’re using it at Planet Argon.

Introducing “LOLBUGZ”

Our team is currently using Lighthouse for managing bugs/tickets for internal and client projects. If there is one way to slow down bug fixing cycle.. .it’s the ticket submission process. It takes a lot of time and commitment to try and communicate some problems that you’ll find in a web application. This is why screenshots can be so useful to helping speed up the process. Skitch allows us to not only provide a screenshot really quickly, but it gives us the ability to focus our attention with shapes and text, which provides more context when viewing an image.

For example, here are a few real-world Skitches that I’ve used to report some problems.

What happened to this drop down?

This pagination needs some CSS-Love!

Oh no! Tags are getting grouped together…

Styling has gone crazy…

I mastered an unordered list! (hooray!!)

This list isn’t scaling anymore…

Side note: LOL BUGZ was a term coined by Rick Olson at Active Reload to describe the tickets that I post for Lighthouse. ;-)

Trying out 15 during the initial releases for the iPhone… bug report sent via twitter to Erik Kastner.

As you can see, using Skitch helps communicate some very specific things without needing to type a huge description. Of course, we do try our best to add more context with our tickets. For example, here is a real-world example of a ticket that I posted on Lighthouse. As you’ll see, there are a few skitches embedded in the tickets, which works much better than attaching screenshots to tickets.

One of the best features of Skitch is it’s work-flow. Within a few seconds, I can do the following tasks.

  • Take a screenshot of a specific region of my screen
  • Add some arrows and text
  • Click on Webpost, which will upload directly to myskitch.com
  • Click on Share to navigate to the new upload
  • Click on the embed textfield and it uses JS to copy the embed html into my paste buffer
  • Paste the html snippet directly into the ticket that I’m reporting
  • Submit my LOL BUG

Side note: it also allows you to upload to Flickr, a ftp account, etc.

Over the past four months, Skitch has become one of my favorite OS X tools. The interface is lightweight and the workflow is almost perfect (feature request: providing the embed code in my paste buffer without needing to go to myskitch would be A+++)

I’ve also used Jing, which works on Windows and OS X and does video. I’ve not found it to be as intuitive for working in this manner. In fact, the work-flow leaves a lot to be desired. However! It does do video and this has come in handy a few times for showing people some “live” interaction-type bugs that can’t be communicated as easily through text/images.

If you’re not using Skitch yet and are on OS X… I highly recommend that you try it out for a few weeks during a bug fixing sprint. We’ve gotten our clients and almost everybody on the team using it in this fashion. The productivity increases haven’t gone unnoticed.

That’s not to say that it’s not fun for point out things that aren’t related to your project bugs. ;-)

Happy Skitching!

UPDATE

Plasq liked the writeup and gave me 50 extra invites to pass out for Skitch. So, if you’re in need of one… ask me via email. Thanks Plasq team!

Starting MySQL after upgrading to OS X Leopard

Posted by Sat, 27 Oct 2007 11:13:00 GMT

If you upgraded to OS X Leopard and are running MySQL from the MySQL.com installer1, you might be having some problems with starting it from the GUI interface. There isn’t a fix from MySQL yet, so to get around that… you can run it from the command-line.

Start MySQL from the command line

cd /usr/local/mysql; ./bin/mysqld_safe &

This should get MySQL up and running for you. If someone wants to share a tip on how to get this to start automatically on reboot, please post a comment and I’ll help get the word out.

1 I didn’t have this problem as I installed MySQL via MacPorts... but this came up for a few members of PLANET ARGON after they upgraded to Leopard.

OS X Leopard Tip: Skitch on Every Space

Posted by Sat, 27 Oct 2007 03:43:00 GMT

If you’re using Skitch and the new Spaces in OS X Leopard, I would encourage you to set the following up.

This will allow you to use Skitch on any Space without needing to move it around. Took me a few minutes to figure out that I could set it up like this.

As you can see… I’m on Leopard now… only took three tries.

Installing Ruby on Rails and PostgreSQL on OS X, Second Edition

Posted by Tue, 19 Jun 2007 18:54:00 GMT

It’s been just over a year since I posted the article, Install Ruby, Rails, and PostgreSQL on OSX and it still gets quite a bit of traffic. Unfortunately, there have been a few changes in the install process that have caught people.

Today, I am leaving my PowerBook G4. It’s being replaced with a MacBook because the logic board is on the fritz. So, guess what that means? I get to install Ruby, Ruby on Rails, PostgreSQL on OS X again! I figured that I would post a revised version of my previous article for those who may go through this same process in the near future.

WARNING: This post contains some outdated instructions. Please read Installing Ruby on Rails and PostgreSQL on OS X, Third Edition, which is focused on Installing Ruby on Rails on Leopard.

Step Zero: Install iTerm (optional)

You’ll spend a lot of time in your terminal as a Rails developer. I’m not a big fan of Terminal.app as it lacks tabbed windows1 and you’ll often find me with around ten tabs open. I’ve been using iTerm for a few years and it’s definitely improved in the past year and doesn’t seem to crash nearly as often as it used to.

Once installed, I always change the default color scheme as I prefer the white on black schema. The menus in iTerm are lacking some thoughtful interaction design, but I’ve figured out the right way to do it (after a long time of stumbling on it by accident). In iTerm, you’ll want to edit the Default bookmark, which you can access by going to Manage Bookmarks under the Bookmarks Menu.

Set the Display value to classic iTerm and you’re golden.

Now… let’s get to business…

Step 1: Install Xcode Tools

Without installing Xcode tools from Apple, we’re not going to get very far. First, you’ll need to grab a copy of Xcode, which you can download on Apple’s Developer Connection site. It’s almost a 1GB download, so you’ll want to start your download and use your multi-tasking skills and grab a Viso, read some blog posts.

I’m going to make the assumption here that you know how to install a dmg on osx. Once this is installed, you can move on to the next step!

Step 2: All Your MacPorts are Belong to Us

MacPorts (formerly known as DarwinPorts) is a package management system for OS X. This is what we’ll use to install most of the necessary programs to develop and run your Ruby on Rails applications. If you’re from the Linux or BSD world, you are likely familiar with similar tools… such as: apt-get, port, and yum.

You’ll want to download MacPorts and install the dmg file.

Now that this is installed, we should test it.

With a new terminal, run the following:


$ port version
Version: 1.442

Success! Let’s get going…

Step 3: Installing the Ruby on Rails development stack

We’re going to go through a series of small steps, which may take some time depending on how fast your internet connection and computer is.

Install Ruby and RubyGems

In order to install Ruby, we’re going to use MacPorts with the port command, which is now available for installing various packages on our OS X machines.

$ sudo port install ruby rb-rubygems

It’ll probably take a while to download and install Ruby and all of it’s known dependencies. In the meantime, check out some funny code. KTHXBYE!

Still waiting for it to install, perhaps you could do something like… begin writing a comment on this post, writing your own blog post, watch a funny video, or recommend me. I walked to Backspace with Gary to get an Americano… and it’s still not done. :-p

(minutes/hours/weeks later)

Okay… I trust that it finished installing Ruby and RubyGems without any hiccups. Let’s test them from our terminal to make sure.

Let’s check the version…


$ ruby -v
ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-darwin8.9.1]

Now, let’s make sure that Ruby is working properly…

$ irb
irb(main):001:0> x = 1     
=> 1
irb(main):002:0> puts "wee!!!" if x == 1
wee!!!

Great, we’re on a roll. Let’s get the rest of the stack installed.

Install Ruby on Rails

We’re going to install Ruby on Rails with the gem command that installing RubyGems provided.


$ sudo gem install -y rails

This command should produce an output similar to the following.


Successfully installed rails-1.2.3
Successfully installed rake-0.7.3
Successfully installed activesupport-1.4.2
Successfully installed activerecord-1.15.3
Successfully installed actionpack-1.13.3

Install Rails-friendly gems

Mongrel

If you’re developing with Rails, it’s highly recommended that you use install and use Mongrel for your development and production environments. The following command will install the mongrel and mongrel_cluster gems (including their dependencies).

$ sudo gem install -y mongrel mongrel_cluster

* Note: Be sure to select the proper platform for mongrel. (hint: OS X is NOT mswin32)

My terminal output:


$ sudo gem install -y mongrel mongrel_cluster

Step 4: Installing the World’s Most Advanced Database Server… PostgreSQL!

At PLANET ARGON, we develop our applications on top of PostgreSQL. I’ve long been advocating the adoption of this awesome open source database in the Rails community. Just over a year ago, Jeremy Voorhis (PLANET ARGON alumnus) and I were interviewed on the Ruby on Rails podcast and had the opportunity to discuss our preference of PostgreSQL over the alternatives (mysql, sqlite, firebird, etc.).

We’re going to install PostgreSQL 8.2 from MacPorts by running the following command.

$ sudo port install postgresql82 postgresql82-server

While this is installing, you might take a moment to check out some space shuttles.

Setting up PostgreSQL

You may have noticed the output of the previous port installation of PostgreSQL 8.2, suggested that you do the following. Let’s do that now…


$ sudo mkdir -p /opt/local/var/db/postgresql82/defaultdb
$ sudo chown postgres:postgres /opt/local/var/db/postgresql82/defaultdb
$ sudo su postgres -c '/opt/local/lib/postgresql82/bin/initdb -D /opt/local/var/db/postgresql82/defaultdb'    

Have PostgreSQL start automatically on system start-ups

Unless you’re concerned about extra applications running in the background, I’d encourage you to add PostgreSQL to launchd, which will start it automatically after system reboots.

$ sudo launchctl load -w /Library/LaunchDaemons/org.macports.postgresql82-server.plist

Adding PostgreSQL commands to your $PATH

For some reason, MacPorts doesn’t add the PostgreSQL programs to the default bash PATH, which means that you can’t run psql, pg_dump, or createdb/dropdb without specifying the full path to where they were installed. What we’ll do is add them to our default terminal profile.

sudo vi /etc/profile
(you can use mate, emacs, joe or any other preferred editor to do this)

This file gets loaded every time a new terminal session is started.

Let’s add /opt/local/lib/postgresql82/bin to the end of the value for PATH.


PATH="/bin:/sbin:/usr/bin:/usr/sbin:/opt/local/lib/postgresql82/bin"    

Save the file and then open a new terminal. To test this, you should get the following output when you run which psql.


$ which psql
/opt/local/lib/postgresql82/bin/psql

Creating a new PostgreSQL user

When I’m working on Rails applications in my development environment, I really don’t want to have to specify a username and password in every config/database.yml file for each of our ongoing client projects. When PostgreSQL was installed, it created a superuser named postgres, which is great, but I’d like one that matches my system username, so that I’m not prompted at all for a username or password to connect to PostgreSQL.

To do this, we’ll use the createuser command, which comes with PostgreSQL. As you can see, I’m creating a new user with superuser privileges (and will hopefully be the last time I have to do a -U postgres).


$ createuser --superuser robbyrussell -U postgres
CREATE ROLE

Let’s take a quick moment to test this out.


# create a new database
$ createdb my_test_db
CREATE DATABASE

# drop the database
$ dropdb my_test_db
DROP DATABASE

Great, everything looks good here.

We now have a running installation of PostgreSQL with a new user account. All we need to do now is install the appropriate RubyGem to allow our Ruby applications to connect to it.

Installing the Ruby Postgres gem

UPDATE: Hydro posted a commented, which lead me to the ruby-postgres gem.

You can install ruby-postgres gem by running the following command.


$ sudo gem install -y ruby-postgres

Let’s take a moment to test that this installed properly.


$ irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'postgres'
=> true

If this returns true, than we should be good to go. We’ve now built a professional development environment for working with Ruby on Rails. Doesn’t that feel great?

Test your install

You can look back at my older post to walk through the process of testing out your setup with a new Rails application.

Closing thoughts

I hope that this post has been useful for you. It took me a few hours to walk through this process and it’s how all of our designers and developers at PLANET ARGON installs and configures their development environment.

We also install the following programs on new machines.

  • TextMate
  • Subversion: sudo port install subversion
  • RSpec: sudo gem install -y rspec
  • ...amongst other gems that are needed on specific projects

Until next time… have fun!

1 Rumor: Mac OS X Leopard will give Terminal.app tabs! (see screenshot)
