Getting Started will guide you through the process of creating a simple Dropwizard project: Hello World. Along the way, we’ll explain the various underlying libraries and their roles, important concepts in Dropwizard, and suggest some organizational techniques to help you as your project grows. (Or you can just skip to the fun part.)

Quantum Computing Playground is a browser-based WebGL Chrome Experiment. It features a GPU-accelerated quantum computer with a simple IDE interface, and its own scripting language with debugging and 3D quantum state visualization features. Quantum Computing Playground can efficiently simulate quantum registers up to 22 qubits, run Grover's and Shor's algorithms, and has a variety of quantum gates built into the scripting language itself.

One of the most powerful features of the CSS preprocessor Sass is the mixin, an abstraction of a common pattern into a semantic and reusable chunk. Think of taking the styles for a button and, instead of needing to remember what all of the properties are, having a selector include the styles for the button instead. The button styles are maintained in a single place, making them easy to update and keep consistent.

The list below contains all the tricks and tips I had to research and integrate in my workflow to keep using Git joyfully in conjunction with SVN. Enjoy!

As reported by Cameron McCormack, Firefox Nightly (version 29) now supports CSS variables. You can get a quick overview in this short screencast:

BayesDB, a Bayesian database table, lets users query the probable implications of their data as easily as a SQL database lets them query the data itself. Using the built-in Bayesian Query Language (BQL), users with no statistics training can solve basic data science problems, such as detecting predictive relationships between variables, inferring missing values, simulating probable observations, and identifying statistically similar database entries.

K-tree is a tree structured clustering algorithm. It is also refered to as a Tree Structured Vector Quantizer (TSVQ). The goal of cluster analysis is to group objects based on similarity. Each object in a K-tree is represented by an n-dimensional vector. All vectors in the tree must have the same number of dimensions.

If there is one thing about testing in Perl which bugs me, it's that most testing in Perl is what cgi-lib.pl is to Plack. The following is mostly a rant and I'm also guilty of many of these sins.

What is repl.it? § It is an online environment for interactively exploring programming languages. The name comes from the read-eval-print loop, the interactive toplevel used by languages like Lisp and Python.
