SSL is an important security and privacy feature for all websites. Its details are outlined in this wikipedia [article] ("http://en.wikipedia.org/wiki/Secure_Sockets_Layer"). At Scibler, we use SSL certificates, encrypting all traffic to and fro from our servers. SSL is a public-key based asymmetric encryption scheme for symmetric key exchange. Symmetric keys are used for payload encryption. On our servers, we use embedded jetty (ring jetty adapter), with the clojure [ring] (https://github.com/ring-clojure) library to handle the http specific functionality.

This is a tutorial about installing SSL certificates on jetty webservers. SSL certificates are X.509 certificates that can be self-signed (authorized by Scibler) or can be signed by trusted third-parties. Trusted third-party certificates are the ones that a Internet user and browsers trust the most. Trusted third-party certification authorities issue certificates per domain and charge a nominal yearly fee.

####Pre-Requisites

The Java JDK has to be

Comparing ES7 and core.async

ES7	core.async
`async function() {...}`	`(fn [] (go ...))`
`await ...`	`(<! ...)`
`await*` or `Promise.all(...)`	`(doseq [c ...] (<! c))`

Create ZFS pool

sudo zpool create -f zroot /dev/sdaX

Create ZFS dataset

sudo zfs create -o mountpoint=/var/lib/docker zroot/docker

Edit /etc/defaults/docker

Connecting to serial port (com port) over network

(Serial port or com port? - Serial ports are often refered as COM ports. It is the same to be short. You can read abut it in the Wiki article )

## The problem Suppose we have an application that works with some device using serial port (com port). It could be GPS reader, IRDA, whatever. So it looks like this:

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. The link points back at them.

Why no pattern matching?

If you are talking about the aspect of pattern matching that acts as a conditional based upon structure, I'm not a big fan. I feel about them the way I do about switch statements - they're brittle and
