Scaling Big Data fabrics

See the original posting on DZone Python

When people talk about Big Data, the emphasis is usually on the Big. Certainly, Big Data applications are distributed largely because the size of the data on which computations are executed warrants more than a typical application can handle. But scaling the network that provides connectivity between Big Data nodes is not just about creating massive interconnects.

In fact, the size of the…

How Pairing & Swarming Work & Why They Will Improve Your Products

See the original posting on DZone Python

If you’ve been paying attention to agile at all, you’ve heard these terms: pairing and swarming. But what do they mean? What’s the difference?

When you pair, two people work together to finish a piece of work. Traditionally, two developers paired. The “driver” wrote the piece of work. The other person, the “navigator,” observed the work, providing review, as the work was…

Scenario planning for first-line managers

See the original posting on DZone Python

A common meme in the strategic planning world is that there is no one pre-determined future. The objective in strategic planning is not to forecast a single outcome but rather to identify a number of possible outcomes. Preparedness comes in having thought through multiple possible end states, and agility comes from the ability to quickly identify which of those end states is coming to fruition…

Why is the Fundamental Theorem of Software Engineering Fundamental?

See the original posting on DZone Python

 Have you heard of the adage “All problems in computer science can be solved by another level of indirection.”? If you are a programmer, chances are you have read about it in a book or an article talking about how to best structure the software you write. It’s been dubbed the fundamental theorem of software engineering (the FTSE) so you should know what it is about. If you…

R: ggplot: Problem automatically picking scale for difftime object

See the original posting on DZone Python

While reading ‘Why The R Programming Language Is Good For Business‘ I came across Udacity’s ‘Data Analysis with R‘ courses – part of which focuses exploring data sets using visualisations, something I haven’t done much of yet.

I thought it’d be interesting to create some visualisations around the times that people…

Geek Reading July 17, 2014

See the original posting on DZone Python

I have talked about human filters and my plan for digital curation. These items are the fruits of those ideas, the items I deemed worthy from my daily reading. These items are a combination of tech business news, development news and programming tools and techniques. You will note that some of the formatting has changed, and that is due to the change in my process.

Docker using private registry

See the original posting on DZone Python

There is an easy way to define Docker container using Dockerfile, you may find it in previous article . There I installed ActiveMQ to Vagrant in Docker without using any registry. The other way to do it is private Docker registry. I will install now MongoDB in a Docker container w/o Dockerfile.
First we need to prepare private registry.

Speaking Resources

I was fortunate enough to recently be accepted to the inaugural php[world] conference. Shortly thereafter, a friend of mine within the community inquired about submitting to and speaking at conferences. I thought I’d post the resources I shared with them here for others interested in the same topic.

YAML Like a Pro

See the original posting on DZone Python

YAML (YAML Ain’t Markup Language) is a cross-programming-language data serialization language whose primary focus is Human Friendliness. This generally means less funny characters like ({}, [], “, etc), so that the data is easier to read and write. These characters are used, but YAML tries hard to make them needed as little as possible; more for harder cases, less so for simple things.

Sharing Programming

See the original posting on DZone Python

I’m going to be volunteer teaching AP computer science this fall at a NYC high school! Aside from actually prepping them for the AP exam, I’ve been thinking about how to share the programming culture I love with the students. Off the top of my head, I’d like to tell them about:

Stuff you can do to program for fun:

Hackathons
Game jams
Project Euler

Where programmers hang…

How to Survive Digital Darwinism a.k.a. Company Failure Acceleration?

70% of the Top 1000 companies are expected to no longer be around in the next decade. Big companies are not adapting to change. Digital Darwinism does the rest.

What is the reason behind Digital Darwinism?

WebGL With Three.js – Lesson 6

See the original posting on DZone Python

Today we continue our WebGL lessons for those who study it and want to enhance their knowledge. In today’s lesson we will look at the load process of ready three-dimensional objects. There are many websites where you can download these models, and moreover, if you have an editor of three-dimensional objects (like 3D Max, Maya, or even Blender), you can create your own models. There are also…

Quickly add Amazon Cloudfront as a CDN

See the original posting on DZone Python

Right now I’m working on an application which is experiencing lots of interest – and therefore lots of load! We needed to look at ways of trying to bring down the pressure on the servers, and decided to use a CDN (Content Delivery Network) for our image files. It was surprisingly painless to implement once I got into it so here it is in case it’s helpful.

Leveraging optical transport to create multi-site datacenter services

See the original posting on DZone Python

The primary objective for networking for decades has been to provide connectivity between resources. In the early days, mere connectivity was valuable enough to make it a service by itself. Then the game shifted to providing bandwidth – essentially more connectivity. Since that time, we have tried different variations of the connectivity-as-a-service model: clean pipes for more secure…

A Rubik’s cube implementation in Three.js

See the original posting on DZone Python

 In 2003, I took the time to put together a page that explains how to solve the Rubik’s cube with a set of formulas that are easy to memorize. The idea was not necessarily to solve the cube quickly (it takes about 50-60 seconds to solve the cube with this approach) but to make it easy for anyone to beat the cube with little effort, as opposed to the hundreds of formulas that speed cubists…

Is agile transformation at risk?
