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

How to install Java JDK8 in Ubuntu 16.04

Let's consider a JDK8 installation using 2 different versions: default and Oracle. The default version is easiest because it is packaged with Ubuntu.

There is default Java installation called the JDK (Java Development Kit). The JDK is usually only needed if you are going to to do some software developmwent using Java or if some software requires it. The JDK does contain the JRE.

Installing the default JDK

Splunk Queries

I really don't like Splunk documentation. Why is it so hard to find out how to do a certain action? So this is a cheatsheet that I constructed to help me quickly gain knowledge that I need.

Google Fu

• “Search Term”

  • This operator searches for the exact phrase within speech marks only. This is ideal when the phrase you are using to search is ambiguous and could be easily confused with something else, or when you’re not quite getting relevant enough results back.
  • ex: “Tinned Sandwiches”
    • This will search for only the finer tinned variety of the bread based snack, at the exclusion of all others.

• OR

  • This self explanatory operator searches for a given search term OR an equivalent term. For instance, if you have an unhealthy fascination with the famous ‘Sheens’ you could search for:

• ex: “Martin Sheen” OR “Charlie Sheen”

ServiceWorker for github pages

This is a ServiceWorker template to turn small github pages into offline ready app.

Why ?

Whenever I make small tools & toys, I create github repo and make a demo page using github pages (like this one).
Often these "apps" are just an index.html file with all the nessesary CSS and JavaScript in it (or maybe 2-3 html/css/js files). I wanted to cache these files so that I can access my tools offline as well.

Notes

Make sure your github pages have HTTPS enforced, you can check Settings > GitHub Pages > Enforce HTTPS of your repository.
