I attend many tech conferences around Europe (and occasionally the World), and Africa is always underrepresented. I was delighted to receive an invite to Afrolynk, an annual event that aims to bridge the European and African entrepreneurial scenes. Entering the Microsoft offices in Berlin for the event, a different crowd greeted me from typical tech and startup events, which was an incredible sight to see.

The day started with a round of drumming to bring people into the room and began a solid day of panels and keynotes. Attendees are sharply and colorfully dressed, energetic, and the variety of languages spoken around the venue highlights the multiculturalism of the African continent.

The concepts of Agile, Scaling Agile, and Business Agility have become buzzwords. The crux of being Agile for the customer and people who are building products and services is buried under a focus on conducting ceremonies.

Prior to scaling Agile, let us not forget the manifesto for Agile software development. It’s all about uncovering better ways of developing software that provides value both to the customer and for people who are part of the delivery stream.

According to a 2014 study, 69 percent of businesses had at least an application or a part of their infrastructure on the cloud.

With the significant number of businesses depending on the cloud, it’s security should be given a serious amount of thought!

In this article, I will explain how to create a global function that can be access or reuse by other Transform Message Component within a Mule Application.

First, We need to create a Dataweave File (.dwl) and save it in src/main/resources/modules/. Now,we can define our global custom functions here by using the fun directive and global variable by using var directive. Also note thatthis dwl file should not contain an output directory, body expression, or the separator (—) between header and body sections.

Of all of the technologies that underpin the 4th Industrial Revolution, AI has undoubtedly received the most hype in terms of its ability to transform the workplace. Breathless tomes have predicted the demise of millions of jobs as automated systems frogmarch their way through workplace after workplace.

Except the reality is somewhat different. A recent report on the state of digital transformation by MIT Sloan Management Review and Deloitte Digital suggests that progress is glacial. This is despite executives telling INSEAD researchers that AI and big data have the biggest potential for disruptive change.

In a classical prediction use case, the predicted output is either a number (for regression) or category (for classification). A set of training data (x, y) where x is the input and y is the labeled output is provided to train a parameterized predictive model.

  • The model is characterized by a set of parameters w
  • Given an input x, for the model predicts y_hat = f(x; w) for regression, or the model predicts the probability of each possible class for classification
  • Define a Lost function L(y, y_hat) for regression, or L(y, P(y=a | x), P(y=b | x) …), find the parameters w to minimize L

This problem is typically viewed as an optimization problem and uses a gradient descent approach to solve it.

A company’s leaders must prepare for the selection, achievement, and continuous improvements of Agile delivery. Only the leadership can evolve and continuously grow the environments in which their people function. Moreover, only these mentors can design the atmosphere that promotes high-performing Agile teams to thrive and deliver excellence. Agile leaders, therefore, must show smarter ways of working so that their people will discover from their personal and professional standards, mentorship and intrinsic motivation. The quest to become an Agilest does not need to be hard. Many leaders have to attempt a new method of management. The process will need to prepare, enable, and challenge their people to attain the highest potential through Agile teachings and practices.

What is not so apparent to leaders is that their people’s knowledge of the processes alone won’t be enough. Agile leaders must take an actual role to guide the new way of working. How many times have I heard from leadership that, "You have my support and contact me if you have any questions"? That way of thinking is a recipe for disaster with Agile. Agile leaders need to involve themselves directly on a daily basis. Get out and walk around, attend daily stand-ups, pop in on Sprint Planning sessions and come to the Sprint Reviews. You want your people to see you are involved with and care about the success of the implementation.
