101 Uses of An Abstract Test #43: Contract Testing As distributed systems have become more and more prevalent, I’ve seen how teams spend an increasing amount of time putting out fires caused by dependencies changing.Team A go to bed with a sp…

As our systems get ever more distributed, devs are spending more and more time fighting fires other teams started.

Here's a simple, but powerful, technique for catching integration fires before they spread.

True value in software isn't solely about new features. Protecting current value, reducing costs, and, crucially, avoiding unnecessary costs are equally important. #ValueDriven #CostAvoidance

SIX new chapters (6 to 11) have been added to the MEAP (Manning Early Access Program) release of our “Effective Behavior-Driven Development" book. They cover Formulation, the practice of turning concrete examples into business-readable specs

Super-intelligence or Superstition? Exploring Psychological Factors Influencing Belief in AI Predictions about Personal Behavior Could belief in AI predictions be just another form of superstition? This study investigates psychological factors that influence belief in AI predictions about personal behavior, comparing it to beli...

There does seem to be a correlation between suggestibility and confidence in AI predictions.

"Notably, paranormal beliefs and positive attitudes about AI significantly increased perceived validity, reliability, usefulness, and personalization of AI predictions."

Refactoring – The Most Important, Least-Understood Dev Skill At the moment, I offer 5 “off-the-shelf” training workshops focused on the core technical practices that enable rapid, reliable and sustained evolution of working software to meet chang…

For every Refactoring workshop booking, I get 41 Code Craft and TDD bookings.

IMO, refactoring is the second most important skill for software developers, but evidently the least understood or valued.

Limiting Work in Progress is still the most efficient way to improve flow of value

I continuously take things back to ground truth: the code as it is now, the tests I specified, the test run results we just got, linter output, mutation testing results etc. I don't let the model tell me it's raining. I go outside and look :-)

Today, looking into instrumenting a big legacy app. I'm super impressed with @augmentcode.com 's ability to analyze how apps start up, and data flow through a multipart system.

Its codebase analysis is top notch.

Where's the Shovelware? Why AI Coding Claims Don't Add Up 78% of developers claim AI makes them more productive. 14% say it's a 10x improvement. So where's the flood of new software? Turns out those productivity claims are bullshit.

Oi reckons, when I apply the practices laid out in my blog series, I get results that are just as good - as in, not as bad - when I'm using a 7B parameter model and when I'm using a 700B+ parameter model.

I see small models in my future.

"Growing Object-Oriented Software, Guided by Tests" by Steve Freeman and Nat Pryce. This book does a great job showing how to iteratively "grow" software using automated tests and how "listening" to tests (and using TDD) leads to better design. amzn.to/4f0sAeG

Building software is a team sport, a means to an end, not the end itself. Don't fall for the false tradeoff between quality and speed – long-term data shows quality enables velocity. #TeamworkInTech #SoftwareDevelopment

The Seven Deadly Sins of “Go Faster” Things that will make your dev team take longer to deliver worse software:1. Adding more people to the team2. Making them work longer hours3. Cutting down on work that “slows them down”…

The most common things engineering leaders think will make dev teams go faster actually have the opposite effect.

AI will never replace testing.

It will expose how broken your tests really are. If your automation is built on code coverage and not behaviour, you’re building illusions.

Software is like inventory, it incurs a cost just by existing. Continuously address maintenance, dependencies, and security to avoid a rapidly increasing basal cost.

I'm vibe coding an e-commerce store for testing purposes. It's a fascinating experience vibe coding the backend then frontend and all the in betweens. It's looking pretty good so far although design is terrible. Need to figure out how to vibe code a good design.

Software development becomes a very different game at different scales.

What works for building a proverbial barbecue over a weekend might bring the house tumbling down on something much more substantial and long-term.
