(dominic: this list of papers was originally recommended to me by Brain Noguchi @bnoguchi, and was a great start to understanding distributed systems)

Here's a selection of papers that I think you would find helpful and interesting:

Time, Clocks, and the Ordering of Events in a Distributed System

The seminal paper about event ordering and concurrency. The important result is that events in a distributed system define a partially ordered set. The connection to what we're working on is fundamental, as this defines how to detect concurrent updates. Moreover, the chosen algorithm to turn the partially ordered set into a totally ordered set defines the conflict resolution algorithm.

JSON Parser in Java

How do I write my own parser? (for JSON)

Password-store keeps your passwords (or any other sensitive information) saved in GnuPG encrypted files organized in ~/.password-store. For more information about GPG, consult the GNU Privacy Handbook.

Getting started

To get started, install pass and generate a keypair.

$ brew install pass
$ gpg --gen-key
$ gpg --list-keys

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

How do you POST a JSON file with curl??

You can post a json file with curl like so:

curl -X POST -H "Content-Type: application/json" -d @FILENAME DESTINATION

so for example:

Jay Kreps of LinkedIn recently made an [excellent detailed 360' overview][log] post explaining why log is an underlying data structure of pretty much everything in distributed systems. Well, I feel tempted to add that same holds true for collaborative editing (like in Google Docs and others). Also, I'd like to point out the relation between partially ordered logs, the offline-first approach, AP systems and the so-called Web 3.0 (like in Meteor, pouchdb and others).

Any real-time approach to collaborative editing decomposes a document into a sequence of atomic operations. The most known one is OT, also there is the WOOT/CRDT based family, including CT. GDocs is an OT system. I did a CT system currently in beta at http://letters.yandex.ru. Note that letters is a tiny pilot project

	Personal Statements and Statements of Purpose

	Personal statements (sometimes called statements of purpose) are essays required from students applying to undergraduate, graduate, or professional school. These statements are different from a job cover letter. In such statements, you are presenting yourself as a potential student. Usually universities or colleges ask you to address specific questions, but sometimes they give only general guidelines.

	There are many approaches to doing these statements. It is especially important, however, to be original, sincere, honest, and to show your interest in the school to which you are applying. It is important that your essay represent who you are – resist the urge to copy models that you find on the Internet.

	Here are several sites that will help you through the process of writing the statement of purpose, or college entrance essays:
