Continuous Delivery for Machine Learning

Martin Fowler

Machine Learning applications are becoming popular in our industry, but teams struggle to develop, test, deploy them. At ThoughtWorks, we've gained great benefits from Continuous Delivery, so we naturally endeavored to apply this technique to our machine learning applications.

Micro Frontends

Martin Fowler

Recent years have seen an explosion of interest in the microservices architectural style, which has become popular due to its ability to allow customer-oriented teams to build and deploy software independently.

Is High Quality Software Worth the Cost?

Martin Fowler

A common debate in software development projects is between spending time on improving the quality of the software versus concentrating on releasing more valuable features.

Design and Run Experiments That Actually Progress Your Business

Speaker: Nick Noreña, Innovation Coach and Advisor, Kromatic

Experimenting as a way to explore new products, services, and business models can help eliminate the guesswork involved in building something your customers actually value. That said, it's often quite tricky to take your vision and figure out the first experiment to run. How do you get started? How can you ensure your experiments are well-designed? Join Nick Noreña, educator, entrepreneur, and currently an Innovation Coach at Kromatic, as he walks us through how we can figure out the right experiments to run for any product or service, and in organizations of all sizes.

Self-serve data platform

Martin Fowler

One of the main concerns of distributing the ownership of data to the domains is the duplicated effort and skills required to operate the data pipelines technology stack and infrastructure in each domain.

Bliki: TechnicalDebt

Martin Fowler

Software systems are prone to the build up of cruft - deficiencies in internal quality that make it harder than it would ideally be to modify and extend the system further.

Don't get locked up into avoiding lock-in

Martin Fowler

A lot of software architects expend time and energy trying to come up with ways to avoid lock-in. Sadly many of these discussions miss important elements of how lock-in works - it's certainly not a simple binary switch. Gregor Hohpe , who's probably spend more time in such meetings that he'd like to admit, has written what I think will be an essential article on the topic. This first installment looks at the different varieties of lock-in.

Domain-Oriented Observability

Martin Fowler

Any serious software system needs some form of observability, so we can figure out how it is working and keep track of problems. But adding the code for this often results in lots of low-level cruft.

How to Design Strong Experiments

Speaker: Franziska Beeler, Head of Cloud Academy, and Tendayi Viki, Associate Partner, Strategyzer

When testing new business and product ideas, choosing the right experiment is just the beginning. After we have chosen our experiment, it’s important that we spend some time designing it well. Join Tendayi Viki, corporate innovation expert and associate partner at Strategyzer, and Franziska Beeler, Head of Cloud Academy at Strategyzer, as they walk us through the three key elements that help you design stronger experiments and come away with the evidence you need to advance your idea.

What I Talk About When I Talk About Platforms

Martin Fowler

Evan Bottcher has been involved with several of our clients with microservices and platform building over the last few years. A couple of years ago, at one of our radar writing meetings, he gave a great presentation on what makes an effective way to think about platforms.

2nd Edition of Refactoring

Martin Fowler

Nearly twenty years ago, I wrote "Refactoring", which is probably my most successful book. It's still a useful book, as the technique is one that doesn't change much with new languages and technology. But given that, a book that uses java.util.Vector is showing its age a bit. So, for the last couple of years I've been working on a new edition.

Bliki: IntegrationTest

Martin Fowler

Integration tests determine if independently developed units of software work correctly when they are connected to each other. The term has become blurred even by the diffuse standards of the software industry, so I've been wary of using it in my writing.

Kindle edition of Refactoring now available from Amazon

Martin Fowler

Amazon is now selling the Kindle edition of Refactoring. As I write this, it's touch more expensive than the hardback since they are currently discounting the hardback but not the electronic version. more…. skip-home-page

The Six Principles of Persuasion

Speaker: Michael Carducci, CTO, Mago:Tech

As senior tech leaders, we often fall prey to thinking that a “good idea” and logical case is sufficient to get the desired response and result. We might be trying to get our CEO on-board with investment in a new technology or a rearchitecture effort, or we might want culture or process changes by our team. Our “good idea” is simply the beginning. An idea must be communicated; a case must be made; and ultimately other people must be persuaded to get onboard. Michael Carducci brings a fascinating background to this webinar. He’s a technologist and regularly works to help senior leaders improve their results. He’s also a professional mentalist and has been a student of psychology, human behavior and the principles of influence for nearly two decades.
