Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

The default is to put this on its own node so you will need to start DSE with dse cassandra -k to create a spark analytics node.

First run the https://github.com/PatrickCallaghan/datastax-creditcard-demo project to populate the Cassandra cluster (follow instructions in README). This project will populate the cluster with credit card data and allow us to filter the results from scala in the spark shell. This will run for approx one minute and finish.

In a new window start the shark shell dse spark

Now you can run the following commands the filter out the required data that is required.

case class credit_card_balance (credit_card_no: String, balance_at: Option[java.util.Date], balance: Option[Double], transaction_time: java.util.Date, transaction_id: String, location: String, items: java.util.Map[String,Double], issuer: String, amount: Double);

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

• From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
• That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost

if [ $# -ne $ARGS ] # correct number of arguments to the script;

OSX Mountain Lion LAMP pear etc Install

If you are really lazy

Install your existing keychains on new mac (there are some files you can just copy, but i can't remember which so maybe give this a go): http://osxdaily.com/2012/07/05/copy-keychain-login-passwords-between-macs/

SSH

• turn on Remote Login from Sharing in System Preferences
• Run ssh localhost, the ctrl+c to cancel (cheap way to create the .ssh directory in home dir)
• Copy private key into .ssh dir and call it id_rsa (make sure perms are 600 or similar)
