MOCKING DATABASE OPERATIONS
===========================

In our webreg example, we refactored some code so that we could
pass in our database object instead of creating it inside. Let's
push that further and show a slightly advanced usage of a mock 
object.

So let's rework our Franchise test to use a mocked database connection.

ExecutionEngine engine = new ExecutionEngine(graphDB);

String query = "start n=node:Person(name={name})
 match n-[:ACTS_IN]->movie<-[:ACTS_IN]-friend
 return friend";
ExecutionResult result = engine.query(query, map("name", "Keanu");

for (Map<String,Object> row : result) {
    Node friend = row.get("friend");
}

The new Secure Password Hashing API in PHP 5.5

The [RFC for a new simple to use password hashing API][rfc] has just been accepted for PHP 5.5. As the RFC itself is rather technical and most of the sample codes are something you should not use, I want to give a very quick overview of the new API:

Why do we need a new API?

Everybody knows that you should be hashing their passwords using bcrypt, but still a surprising number of developers uses insecure md5 or sha1 hashes (just look at the recent password leaks). One of the reasons for this is that the crypt() API is ridiculously hard to use and very prone to programming mistakes.

// Enter the day you would like to create
WITH { day: 18, month: 1, year: 2014 } as dayMap

// Merge hours in a day
MERGE (thisDay:Day { day: dayMap.day, month: dayMap.month, year: dayMap.year })
MERGE (firstHour:Hour { day: dayMap.day, month: dayMap.month, year: dayMap.year, hour: 1 })
CREATE (thisDay)-[:FIRST]->(firstHour)
FOREACH (i IN tail(range(1, 24)) |
    MERGE (thishour:Hour { day: dayMap.day, month: dayMap.month, year: dayMap.year, hour: i })
    MERGE (lasthour:Hour { day: dayMap.day, month: dayMap.month, year: dayMap.year, hour: i - 1 })

# put this in your .bash_profile
if [ $ITERM_SESSION_ID ]; then
  export PROMPT_COMMAND='echo -ne "\033];${PWD##*/}\007"; ':"$PROMPT_COMMAND";
fi

# Piece-by-Piece Explanation:
# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
# the $PROMPT_COMMAND environment variable is executed every time a command is run
