Comparing Strikers Statistics

See the original posting on DZone Python

Here we compare the scoring statistics of four of the best strikers of the recent football history: Del Piero, Trezeguet, Ronaldo and Vieri. The statistics that we will look at are the scoring trajectory, scoring rate and number of appearances.

To compute these values we need to scrape the career statistics (number of goals and appearances per season) on the Wikipedia pages of the players:

What is Product Management?

See the original posting on DZone Python

I often get asked what it takes to be an effective product manager or product owner, which product skills the individuals should have, and how a company can strengthen its product management function. Answering these questions requires an understanding of what effective product management looks like in the digital age.

In the development of most services there is a need in the internal billing for service accounts. Our service (http://bitcalm.com) also had such a problem. We were not able to find ready-made packages for its solution and in the end had to develop a billing system from scratch.In this article I want to talk about our experiences and pitfalls encountered during development.

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.

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

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

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…

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…

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

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…
