Introduction

The default version of java provided in the latest raspbian images are outdated, so we are going to install from the ppa:webupd8team/java repository instead. Please note that add-apt-repository ppa:webupd8team/java will not work, so we will need to add the repository manually.

Installation

1. Create the gpg key file and paste the following lines of text below

nano key.txt

Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

Clojure Destructuring Tutorial and Cheat Sheet

(Related blog post)

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

From Out of the Tar Pit:

The key problem with testing is that a test (of any kind) that uses one particular set of inputs tells you nothing at all about the behaviour of the system or component when it is given a different set of inputs. The huge number of different possible inputs usually rules out the possibility of testing them all, hence the unavoidable concern with testing will always be — have you performed the right tests?. The only certain answer you will ever get to this question is an answer in the negative — when the system breaks.

This is a strong argument for some form of generative, simulation, or property-based testing.

This is an experiment for possible faster boot time (and consequently faster feedback) when running tests. I ask your help to try this in your apps (any Rails 3.x app) and let me know how well it works.

Add the following lines inside the configuration block in config/environments/test.rb:

Hi [your name here], thanks for getting in contact with me.

I sincerely appreciate the interest in [your company name here] hiring me, however there is several problems with this:

1. I have just signed a lease on a new property in Melbourne. The lease is for one year. This means that I am effectively tied to Melbourne for one year.
2. I have only recently (November) started a job for Spree Commerce. I like/love this job and would like to stay there.
3. I have no formal qualifications past a certificate IV in Network Administration. I think qualifications are bullshit. Getting me into America would prove very difficult for your company. I am, of course, assuming you would want me on-site. Although I've written a book on the framework that I'd be hired to do work with, I doubt that would assist the process any. See #1 also for a very valid reason why this would not be possible.

I think that you would have more of an effect just by getting to know one person really well than getting to know one hundred peopl
