Building Ubuntu Bootable USB
Download iso for ubuntu (currently using Ubuntu 14.04.4 LTS (Trusty Tahr)
cd ~/Downloads (change this if your download was to a different location)
execute the following to convert iso to format more easily handled by OSX
Hdiutil convert -format UDRW -o ubuntu.iso [name of iso downloaded]
determine usb device name
Before inserting usb, execute ‘diskutil list’
Execute ‘diskutil list’, the newly displayed device will be the usb
I am sure this is not new for many but I wanted to capture for my own sanity in the future. The following can’t be executed at the command line and in my case on OS X. The first script Will undeploy a given webapp by context.
many times, when working with people. You can become somewhat sedentary in your expectations of people. This is not the case when speaking of these such three. They are pushing each other to think differently. They are pushing each other to capture their thoughts (and document). And more importantly… they are pushing themselves to start to have an opinion even if the opinion doesn’t always meet the norm.

I write this post as a means to dump my brain to paper. I have been meeting with a co-worker on a weekly basis with the purpose of allowing this person to gain an understanding of the process of writing software (test driven development, engineering practices, etc.). This person is Mr. Mattie Righter (http://matthewrighter.com/). In meeting with Matt weekly, I have asked him to start the process of writing with the sheer purpose of capturing his thoughts. I believe writing down his thoughts and opinions over time allows each of us to see his growth.
A couple of days ago I was reading this article on paired programming. I knew he was somewhat challenged by the process and had opinions he felt were differing from others within the company. And differing from others in the profession as well. After reading this article and feeling it was well written and well thought-out and information that would probably be well consumed by the populace, I tweeted it to all the people that follow me. It is with great pleasure that I going to say that many people have retweeted and made very positive comments about his writing style and content. So I’m writing this blog post in hopes that others in similar situations as Matt will take the opportunity to start documenting their thoughts and their beliefs. The process of documenting anything allows a person to solidify their opinions about many things. If you follow me on a regular basis or if you do not for that matter and you just happened to catch this blog post via my Twitter feed, please take a few minutes and cruise over to Matt’s website and read his post on pair programming. I have attached the link. Do not feel obligated to leave a comment, but if you enjoyed the read or did not, leave some feedback. When someone is documenting their thoughts and beliefs, this feedback, whether positive or negative is a good litmus as to the content they are publishing. Thank you for your patience as I post this type of information and hopefully promote one of my very talented co-workers.
as part of my weekly get together with Mattie Righter, he and I are working through the ever craft kata. I have not made quite as good of progress as he, although I am slowly making it through it. I’m spending most of my time attempting to make the kata purely functional with no side effects of any kind.
Feature: Create a Character
As a character, I want to have a name so that I can be distinguished from other characters
- can get and set Name
So, I have already decided to violate/change the requirements of Feature 1. I do not like the idea of a character possessing the ability to change their name. I am deciding to prevent the ability to change your name.
As a character, I want to have an alignment so that I have something to guide my actions
- can get and set an alignment
- alignments are Good, Evil and Neutral
I decided to create a ‘sealed trait’ for Alignment with the possible values of Good, Bad and Neutral. I like the idea of not seeing string values within the code. This also makes it very clear when reading the code and prevents others from accidentally creating unwanted ‘Alignments’.
I have decided to default a newly created character to an alignment of ‘Neutral’. I have not provided a constructor for anything other than Neutral. If the character is to be anything other than Neutral, then setting after creation will be required.
Feature: Armor Class & Hit Points
As a combatant, I want to have an armor class and hit points so that I can resist attacks from my enemies
- has an Armor Class that defaults to 10
- has 5 Hit Points by default
Nothing crazy here… I just followed the directions.
Feature: Character Can Attack
As a combatant, I want to be able to attack other combatants so that I can survive to fight another day
- roll a 20 sided die (don’t code the die)
- the roll must meet or beat opponents armor class to hit
I created an Attack ‘sealed trait’ that will confine the possible Attack types to ‘Hit’ and ‘Miss’. When a character attacks an opponent, the roll (1-20) is used to determine if the opponents hit points and the roll constitute an attack of ‘hit’.
Feature: Character Can Be Damaged
As an attacker, I want to be able to damage my enemies so that they will die and I will live
- If attack is successful, other character takes 1 point of damage when hit
- If a roll is a natural 20 then a critical hit is dealt and the damage is doubled
- when hit points are 0 or less, the character is dead
I am debating if the ‘attack’ should be part of the character. It seems like it should be a separate class that takes two opponents and a role value… and returns the result. This way the opponent is not required to own the attack logic.
Feature: Character Has Abilities Scores
As a character, I want to have several abilities so that I am not identical to other characters except in name
- Abilities are Strength, Dexterity, Constitution, Wisdom, Intelligence, Charisma
- Abilities range from 1 to 20 and default to 10
- Abilities have modifiers according to the following table:
