An opinionated list of excellent Clojure learning materials

These resources (articles, books, and videos) are useful when you're starting to learn the language, or when you're learning a specific part of the language. This an opinionated list, no doubt. I've compiled this list from writing and teaching Clojure over the last 10 years.

• 🔴 Mandatory (for both beginners and intermediates)
• 🟩 For beginners
• 🟨 For intermediates

Execute stored procedure with BLOB parameter in PHP with OCI

<?php
define('DB_USER','user1');
define('DB_PSWD','pswd1');
define('DB_CONN_STR','MYTNS');
define('DB_CHARSET','AL32UTF8');

<?php

include __DIR__ . '/threads.php';

$commands = array();

for ( $i=0; $i<10; $i++ ) {
	$commands[] = "bash -c 'sleep `shuf -i 1-5 -n 1`; echo $i'";
}

In case you want to run ansible (or ansible-playbook) command against a set of hosts that makes sense only for one run, you can don't bother to create one-time inventory file, but simply define a comma-separated list of hosts as argument of --invertory option (or its short form that's simply -i) as follows:

ansible --inventory=myhost1,myhost2,myhost3 all -m setup -a 'filter=*name*'

(note that all in this command line stands for the target hostname)

If you have only one host to run your playbook against, your inventory string must ends with ,

Example invocation of a RabbitMQ docker container (use -d instead of -t -i to run in the background):

docker run -t -i --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3-management

Example of controlling the rabbitmq-server inside the container using rabbitmqctl (also inside the container).

docker exec rabbitmq rabbitmqctl status
