Visualization of probabilistic forecasts

This week my research group dis­cussed Adrian Raftery’s recent paper on “Use and Com­mu­ni­ca­tion of Prob­a­bilis­tic Fore­casts” which pro­vides a fas­ci­nat­ing but brief sur­vey of some of his work on mod­el­ling and com­mu­ni­cat­ing uncer­tain futures. Coin­ci­den­tally, today I was also sent a copy of David Spiegelhalter’s paper on…

Different Ways of Scaling Agile

See the original posting on DZone Python

At this year’s Construx Software Executive Summit one of the problems that we explored was how to scale software development, especially Agile development, across projects, portfolios, geographies and enterprises.

The major advantage of Agile at scale isn't the ability to react to continuous changes or even to deliver faster or…

OOP in Python – Part 1

See the original posting on DZone Python

What is OOP (Object Oriented Programming) ?

Object Oriented Programming is a programming paradigm which creates “objects” during the phase of programming, by this trying to model the entities from the problem which is need to be solved.

The “objects” contain data as form of fields (also called attributes) and have operations defined (called methods). The “objects” have a type…

Geek Reading November 19, 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.

R: Refactoring to dplyr

See the original posting on DZone Python

I’ve been looking back over some of the early code I wrote using R before I knew about the dplyr library and thought it’d be an interesting exercise to refactor some of the snippets.

We’ll use the following data frame for each of the examples:

Engineering Joke of the Week: The Frog

See the original posting on DZone Python

A young engineer was crossing a road one day when a frog called out to him and said, “If you kiss me, I’ll turn into a beautiful princess.” He bent over, picked up the frog and put it in his pocket.

The frog spoke up again and said, “If you kiss me and turn me back into a beautiful Princess, I will stay with you for one week.” The young engineer took the frog out of his pocket, smiled…

People over Process

 Here are the slides from my Keynote at Lean Into Agile Conference:
Overview

Agile and Lean are a means to an end. Once we are clear what our goals are and our approach is consistent with what we truly value, then we may hope for success.

R: Joining multiple data frames

I’ve been looking through the code from Martin Eastwood’s excellent talk ‘Predicting Football Using R‘ and was intrigued by the code which reshaped the data into that expected by glm.

Does Agile require cultural change?

See the original posting on DZone Python

If Woody Allen were an Agile Coach Consultant he might say:

“#Agile without culture change is an empty experience; but as empty experience go its one of the best”

I sit in Agile conferences (and I include Lean and Kanban here) and I hear people say “To really become Agile you need culture change.” And I agree with them.

Yes, if you really want to be Agile, and get the greatest…

People want Swiss Army Knives

I ran across this graphic this morning on Twitter:

Obviously the intended message is that scalpels are better than Swiss Army Knives. Certainly the scalpel looks simpler.

hack.summit() On Pace To Be Largest Developer Conference Ever

See the original posting on DZone Python

I just wanted to let everyone know about this great virtual developer conferencing coming up called hack.summit(). Most of us in the tech community are used to attending a certain number of conferences a year—and certainly we can admit it’s not always easy to drop everyone we’re doing to jet to Silicon Valley. For one, the costs of attending the big conferences can be overwhelming, and your…

How the Internet of Things Will Change How You Live

See the original posting on DZone Python

Social media, mobile connectivity, Candy Crush—these things are old
news. There is a bigger, badder technological revolution occurring: the
Internet of Things, aka the IoT, in which everything from appliances to cows to
us is online. This may seem like something out of a science fiction novel, but
make no mistake, it’s coming. Cisco IBSG has predicted that by next year there
will be 25…

Syncing Brackets extensions across multiple machines

See the original posting on DZone Python

This really isn’t a new tip, but as someone just asked on Twitter for a quick explanation, I thought I’d write it up. If you want to sync Brackets extensions across multiple machines, the easiest way to do it is with Dropbox, or a Dropbox-like service. As long as it creates a physical folder on your machine, you can simply store your extensions there (for me it is…

Some Thoughts on Agile Transformation in Big Companies

See the original posting on DZone Python

As usual… I’ve gotten a little sidetracked on my Agile 101, 102… series of posts. I’ve got the 201 post half finished, but haven’t been able to spend the time getting over the hump. That said, I want to divert just a little and talk about agile in general, explore some of what it is, and a little about where it’s going. I think we have created a bunch of confusion in the marketplace.

4 Developer Career Journeys

If you’re trying to figure out whether you want to embark on a certain career path, or if you’re trying to find out how one breaks into that same career field and then progresses through it, I think it’s helpful to listen to the stories of people who have walked that path before.

The power of Clustering Illusion when managing image

See the original posting on DZone Python

As humans, we are predisposed to finding order out of otherwise random data. When we look at clouds or even a mountain ridge, we find shapes that are familiar to us. When we see data, we instinctively search for patterns to help make sense of what might appear to be random information. It might be our inherent need for understanding. Or maybe we are just programmed to compare things to stuff we…
