Newsletter - June 2017


This month we've included everything you ever wanted to know about F# Active Patterns, why developers find it difficult to convince managers to let them 'do TDD', the results of GitHub's Open Source developer survey and a note on transparent salaries. Phew.

Kind regards, The Codurance Team

Our opinion on... open financials and open salaries.

Since we started Codurance, we always wanted to have our employees involved with all aspects of our business. Besides trusting them as craftsmen, we would love to have their input on how to build a great company. In order to maximise everyone’s contribution, we felt that everyone should have access to the same amount of information, and that includes all the financials and salaries. Although scary, we knew that it was the right thing to do. So, 2.5 years ago we opened all our financials. From that day, every single employee has had full access to the company’s financials. This includes: Salaries, Revenues by project, Project contract details, Assets, Liabilities, Cashflow, Costs, and Taxes we pay.

Looking back, it was one of the best decisions we’ve made. That decision supported our culture of openness and transparency. Two and half years later and 3 times bigger in size, we can have very open conversations about the direction of our business, the importance of each client, we can discuss which benefits we can provide, we can openly discuss new hires, which investments we are all comfortable to make, and many other things. Codurance would never be the company it is today without the open contributions from all our people. There is no elephant in the room anymore and we can all focus on making our company a place that we all love.

(Nearly) Everything You Ever Wanted to Know About F# Active Patterns

Paulmichael Blasucci provides a concise, but thorough, review of one of the more unique features of the F# language: active patterns.

How do I convince...?

We often get asked questions along the lines of 'how do I convince my manager to allow us to do TDD'. Sandro's blog post looks at why focusing on practices, rather than starting with solutions and working backwards, often holds development teams back from introducing new technical practices.

The Practical Dev Twitter Thread

This thread started in May and we didn't have time to include in the last newsletter ... so here it is. A useful Twitter thread covering useful programming tools that we kept tabs on as it developed.

Not even wrong - ways to dismiss technology

'For a theory even to be wrong, it must be predictive and testable and falsifiable. If it cannot be falsified - if it does not make some prediction that could in theory be tested and proven false - then it does not count as science.'

How AWS Cloud is demolishing the cult of youth

James Governor (Red Monk)'s look at how Amazon Web Services have been strategically hiring some of the most well know experts in the Software industry, and how this runs against the grain of the 20's hiring myth.

The broken promise of static typing

Daniel Lebrero attempt to empirically prove, via GitHub issues labelled as bugs across repos, as to whether static types produce more bugs. Includes interesting charts and a few takeaways in the conclusion.

Sandro Mancuso Episode 6 on Yellow Duck Podcast

Earlier this week, Sandro was invited to the Yellow Duck Podcast, a dedicated to software technology, developer problems and solutions. Catch Sandro's views on Software Craftsmanship, such as when it's appropriate to adopt or drop certain aspects of being a Craftsman.

Open Source Survey

GitHub teamed up with researchers from academia, industry, and the community to produce this survey on the attitudes, experiences, and backgrounds of those who use, build, and maintain open source software. Interesting reading.

Haskell for all: Translating a C++ parser to Haskell

Gabriel Gonzalez's instructive example of how C++ idioms map to Haskell idioms, through his recent translation of Nix's derivation parser. Yep.

DNS Infrastructure at GitHub

Blog post from the GitHub engineering team on designing a new DNS infrastructure, aiming to improve operational issues (including scaling and visibility), as well as introducing some additional requirements.

This Could Mark the End of the Silicon Age

'A team lead by the University of Utah has discovered a new group of materials called organic-inorganic hybrid perovskites that could bring spintronics from a largely conceptual concept into reality.'

Codurance's Crafted Design Course

Crafting Code course has been delivered to over 1,000 developers across Europe, introducing the ethos of Software Craftsmanship via Clean Code, TDD (Classicist and Outside-In) and techniques to deal with legacy code. Our new Crafted Design course brings these skills to a new level, purely focusing on the design aspect of software development, from emerging design through TDD, all the way up to designing micro services. 

My First Year at Codurance
