ERCIM News No. 145 Special theme: "E-Values - Statistical Testing for the 21st Century"

ERCIM NEWS No. 145 -

Dear ERCIM News reader, ever heard of e-values?

If not, you're probably not alone. 

Michael I. Jordan opens this issue with a keynote introducing the concept:

What is an “e-value” and why has it become an object of intense study in statistics and in the allied fields of machine learning, signal processing, and econometrics? To briefly introduce the basic idea, let us consider one of the core problems in statistics – the “hypothesis testing problem” of deciding whether observed data is consistent with some particular data-generating mechanism (often referred to as a “null hypothesis”) or is better explained by another mechanism (referred to as an “alternative hypothesis”). This problem is addressed by defining some function of the data (a “statistic”) whose distribution is as different as possible under the null and the alternative. Given an observed value of such a statistic, one then makes a choice between the two distributions, doing so in a way that minimizes the probability of errors. Classical statistical theory provides a unifying framework – the “p-value” – by which the choice between the null and alternative hypotheses reduces to a thresholding procedure.


Guest editors Peter Grünwald (CWI and Leiden University), Wouter Koolen (CWI and University of Twente) and Johanna Ziegel (ETH Zurich) guide readers through this emerging framework for quantifying statistical evidence. 

The articles in this special theme demonstrate how it is already finding applications across many areas of scientific research, from clinical trials and microbiome studies to political polls, AI evaluation and financial risk backtesting.

I must admit when I read 'e-values', I thought of an e-rendering of ethics - humanities and sciences (qualitative-quantitative : subjective-objective : ...), but as always a welcome resource.

^As a community mental health nurse I have a problem with the betting and gambling industries. Yes, many participants 'gamble responsibly', they know when to take a break. They understand the house rules. For a significant number of the population, they are vulnerable. Bitcoin is another example. There the 'house' is continually re-built after successive collapses. But the mathematics here in p-values, v-values and in clinical reasoning is also significant as a crucial element whether naive or formal research.

I have always thought that -

  1. Hodges' model presents an implicit theory (as per many models - given their purpose).
  2. It follows, that Hodges' model can also do a lot of work.

"Passport please!"

Press release

'Innovator passports’ set to accelerate cutting-edge NHS care

The move is a key part of the government’s Plan for Change and its 10 Year Health Plan, which will transfer power to patients and transform how healthcare is delivered, creating an NHS fit for the future.

For too long, cutting-edge businesses avoided working with the NHS and went elsewhere, weighed down by slow timelines and reams of processes. Now, organisations will be able to join up with the NHS quicker than ever before through the removal of needless bureaucracy. Not only is this better for patients but also for our NHS and economic growth.

A ‘one-stop shop’ thorough check from the NHS will now allow businesses to get to work as quickly as possible and deliver on what matters most to patients across the country. It means NHS patients will get more effective treatments and support quicker, and the NHS will make the most of its finite assessment resource, all while businesses are given a boost through the government’s industrial strategy.

Treatments including special wound dressings - already reducing surgical site infections by 38% at Barking, Havering and Redbridge University Hospitals - could be adopted more widely, benefiting patients across the country.

At Barts Health NHS Trust in London, use of antimicrobial protective coverings for cardiac devices has cut infections and saved over £103,000 per year. At University Hospitals Dorset, adopting rapid influenza testing reduced bed days and antibiotic use, freeing up vital resources.

The new passport will eliminate multiple compliance assessments, reducing duplication across the health service. It will be delivered through MedTech Compass, a digital platform developed by DHSC to make effective technologies more visible and widely available.

MedTech Compass will make these innovations and the evidence underpinning them clear to buyers within the NHS.

The initiative builds on the government’s drive to slash waiting lists and ensure people have access to health and care when and where they need it under the Plan for Change.

Wes Streeting, Secretary of State for Health and Social Care, said: 

For too long, Britain’s leading scientific minds have been held back by needless admin that means suppliers are repeatedly asked for the same data in different formats by different trusts - this is bad for the NHS, patients and bad for business. 

These innovator passports will save time and reduce duplication, meaning our life sciences sector - a central part of our 10 Year Health Plan - can work hand in hand with the health service and make Britain a powerhouse for medical technology.

Frustrated patients will no longer have to face a postcode lottery for lifesaving products to be introduced in their area, and companies will be able to get their technology used across the NHS more easily, creating a health service fit for future under the Plan for Change.

Dr Vin Diwakar, Clinical Transformation Director at NHS England, said:

We’re seeing the impact improvements to technology are having on our everyday lives on everything from smartwatches to fitness trackers - and we want to make sure NHS patients can benefit from the latest medical technology and innovations as well.

The new innovator passports will speed up the roll-out of new health technology in the NHS which has been proven to be effective, so that patients can benefit from new treatments much sooner.

It also forms an important element of the industrial strategy through the upcoming Life Sciences Sector Plan, which will turbocharge Britain’s life sciences sector and cement the UK’s position as a global innovation leader.

MedTech Compass helps speed up decision-making in trusts, allowing technology to scale faster - making it easier for trusts across the country to find, assess and adopt proven technologies that improve and speed up patient care.

The passports mean that once a healthcare tool has been assessed by one NHS organisation, further NHS organisations will not be able to insist on repeated assessments, reducing the need for local NHS systems to spend their limited resources on bureaucratic processes that have already been completed elsewhere.

The digital system will act as a dynamic best buyer’s guide, making it easier for trusts to compare products side-by-side in one place.

In my source (below) Laura Hughes also notes:
'However, the Financial Times has reported on calls by frontline workers for basic NHS infrastructure to be brought up to a minimum standard before politicians extol the virtues of cutting-edge tech.

Matthew Taylor, head of The NHS Confederation, which represents health managers, said not all NHS organisations were at the same stage of digital maturity, which would "affect their ability to either innovate or implement preapproved innovation in this passport model."'

c/o Ridgway - assimilation & accommodation

An approach to testing and teaching

'Consider the problems of acquiring new knowledge; two ideas are particularly important. The first is that existing knowledge and conceptual structures affect the way that new materials are perceived and learned; the second is that new experiences bring about changes in our knowledge and conceptual structures. These two processes are referred to as assimilation (analogous to the way in which the stomach digests food, whose later structure cannot be recognized as being similar to its earlier structure) and accommodation (analogous to the way that the pupil of the eye adjusts itself different light levels). Biological analogies make it easier to understand these concepts but leave unresolved the question of when one accommodates and when one assimilates. In general, one accommodates (i.e. changes one's conceptual structures) when fresh knowledge provides strong challenges to what is in mind; so dramatic counter-examples to currently held beliefs, or coherent patterns in the world, which cannot be explained by existing beliefs are both likely to bring about accommodation. Assimilation (interpreting new events in terms of old ideas) can be made to work when the number of counter-examples to predictions made from old beliefs are rather low. It follows, therefore, that if misconceptions are to be remedied (i.e. the mechanism of assimilation is overcome and the mechanism of accommodation stimulated) a representative sample of questions in the domain of interest is unlikely to have the desired effect because the number of cases which violate pupils' misconceptions and which therefore  might cause accommodation, will be relatively small. To foster accommodation it is necessary to provide dramatic examples which violate current conceptions and to provide these examples in quantity. Examples which are most likely to be dramatic are those in which it is obvious to pupils that the results they are obtaining using particular misconceptions are at variance with what they 'know to be true' from everyday experience.' pp.46-47.

Safety testing time - evaluations - for users of Hodges' model to be extended

The time to test Hodges' model* is to be extended (in my dreams...).

Or. Do not underestimate 'simple' models.

The time to evaluate Hodges' model:

  • for individual users
  • cross-curricula
  • professional groups (e.g. registered mental health; and general nurses)
  • within multidisciplinary / skilled teams / venues (Nursing home, Community Mental Health Team)
Given the universal, multicontextual scope of the model for public and patient safety it was decided to extend the time for testing by a further month to two quarters [ 😉] - six whole calendar months.

When applied it is important that checkpoints are agreed:

  • Data gathering - initial interview
  • initial formulation / care plan
  • care review / evaluation
  • discharge - staying well 
There is no agreed standard for testing a generic model in healthcare. Is there?
  • Not for the medical / bio-medical model
  • Nor, for the biopsychosocial model?
What chance then for a biopsychosociopolitical model?

*Per user and group of users of course.

Book review: #4 - Handbook on the Ethics of AI

Chapter 7 is no doubt one of the engine rooms of this book. In AI Ethics and Machine Ethics, John-Stewart Gordon follows preceding authors citing Nyholm and others. This probably helps the overall coherence of the book, and underlines what is a dynamic and emerging field. Reading 'What is AI ethics?' (p.98), I made a note about our humanity's cognitive house-keeping (and other life-forms?) executed through sleep, the ability to unlearn, and forget. Efforts to mitigate machine bias are provided in a list 1-5 (p.100). As observed previously, this author is also thinking on their feet (and very well too) with 'Source: Author's own' in a figure for the systemic place of machine ethics and another (table) 7.1 'Four approaches to machine ethics'.

3.4 considers the challenges involved in developing ethical AI systems. As in healthcare, we see where the (problem of) 'many hands' emerges from:
'Developing ethical AI systems requires collaboration between computer scientists, ethicists, and other stakeholders, which can be challenging due to differences in expertise, terminology, and perspectives. Computer scientists bring technical expertise to the table, while ethicists provide insights on moral principles and values that should guide AI behavior. However, these experts often operate within their own domains and may lack a common language to effectively communicate and collaborate. 
Other stakeholders, such as policymakers, industry professionals, and end-users, also play vital roles in shaping the ethical development of AI systems. They bring diverse perspectives, needs and expectations that need to be considered and balanced during the design, implementation, and regulation of AI technologies. For instance, policymakers are responsible for creating guidelines and regulations that ensure the safe and responsible use of AI, while industry professionals must adhere to these standards and navigate the practical challenges of integrating ethical considerations into their AI-driven products and services.' p.104.
The solution includes having interdisciplinary and ethnically diverse teams, cross-disciplinary training, and a more holistic and comprehensive approach to AI development. Unintended consequences (a news item today (13th Feb 2025) are discussed, the dual-use nature of AI and technological 'delivery' surveillance acting for good and potentially ill (China's - Social Credit Point System).

AI ethics is also itself apparently a conceptual framework (p. 99,107).

What is permitted by law in a State clearly varies. Chapter 8 deals with From Ethics to Law: Why, When, and How to Regulate AI. Collingridge is another recurring citation, and presents a dilemma no-less (Section 3. p.116); one to follow up  (Coeckelbergh too, chap 9). I've always felt that some knowledge of social and economic history is a good foundation. History is reflected here in resort to 'masterly inactivity' (p.118) and regulatory approaches - as debated this past week at an AI Action Summit in France. 

I can still recall the sense of competition in having time in the sandpit at infants school.* Software developers will use sandboxes to develop and revise code in an isolated environment, before it goes live, or wild. With AI the book refers to mishaps, projects that have gone wrong. We need to take care regards the nature of the 'sandboxes' that are used. In a way this speaks to the utility of Hodges' model as a resource for lifelong learning, a learner being fully socialised into a profession and its evolving disciplines:

I had to look up the CREEPER (Curbing Realistic Exploitative Electronic Pedophilic Robots) ACT (p.121). We are accustomed to outsourcing, and its perverse effects facilitated through globalisation, with nations transferring their pollution - plastics, and e-wastes. There are efforts as Chesterman writes to limit outsourcing to AI in terms of the decisions (pp.122-123). I enjoyed the nods to Isaac Asimov too. 

Gellers in chapter 9 AI, Design, and More-than-Human Justice provides another cylinder to drive the text not just forward but acknowledges the future for all: organic and inorganic. Gellers is argues for attention to AI and justice, not merely the moral and legal status of AI. Reading of  'communities of justice' (p.128) the established notion of 'communities of practice' or the collective of users - socio-technically. Gellers highlights our being in the anthropocene and how the environment and nature is figuring in law. So, not just legal questions for humans but natural 'things' and entities also (posted previously: Person & Sense of Place: A River runs through it ...).

I don't think we are there yet? Even, accepting that built-in obsolescence is an established and legal thing. But AI could turn materialism on its head. Looking at the materials, metals, rare earth elements ... that goes in how long do they last and how are the materials recovered? AI, computing desperately needs the doughnut economy, must epitomize the doughnut. Looking for a place to live, you notice the way probably quite serviceable bathrooms and kitchens are ripped out. The suites on a skip. That is quite a scene on the rubbish tip in the film: 'A.I. Artificial Intelligence'. The amount of energy in total production and materials is still not wholly valued, even before other values are 'added'? The focus on design here is integral to such questions. It has brought me to care design, and care architecture. Socio-technical aspects are highlighted again by Gellers (for me, as noted on W2tQ, that hyphen matters). 

Unsurprisingly, Descartes also figures in this chapter, section -Technology in the anthropocene:

'First, for philosophers of technology, the Anthropocene obliterates the nature/culture divide intrinsic to Cartesian thinking (Conty, 2017) that altered the course of history by rebranding technical objects as artificial and thus divorced from nature (Hui, 2017).' p.131.
It is encouraging that there is now recognition that 'we are nature too'. While we can record thought - brain activity on an EEG, from the outset (school studies of biology, then human biology) I've always associated intelligence, mind, thought, emotion, hope, dreams and cognition .. with the intra- interpersonal domain. If you adopt a socio-technical approach (overview - mindset) then invariably the technosphere will straddle the HUMANISTIC <-> MECHANISTIC axis of Hodges' model:
'So far, I hope to have established that technology plays a prominent, if complicated, role in the Anthropocene. But how does this relate to justice? Technology's relationship to ecological systems holds important implications for determining who belongs to communities of justice. To begin, the Earth system consists of interrelated biological, physical, and mental "worlds" (Kotzé, 2020, p. 80). The mental world, also referred to as the "technosphere," is an autonomous amalgamation of energy, communication, transportation, and financial systems, along with cities, governments, factories, farms, and other built systems and their constituent parts (Haff, 2014, P. 127). Technological artifacts such as AI are therefore part of the technosphere.' p.132.

Hodges' model: axes and care domains

We read of robots-in-ecology and robots-for-ecology. I was reminded of the SF film 'Silent Running' here. The real merit and encouragement for me in Geller's contribution, is section 4 which compares how we can approach more-than-human justice. Total eclipses are supposed to be rare, irrespective of what they might portend, now AI, the climate and life on Earth keep eclipsing each other: thus far partially. 4.1 Multispecies justice - Peter Singer really is ahead of his time (chapter 11 - here!); following socio-ecological justice 4.2, we arrive at planetary justice. Note (in Hodges' model) the 'distance' of what is generally deemed social and where the ecological in reality - physically resides. In the margin I'd scribbled 'Less a case of "take me to your leader" and more a case of "show me all your cards!"'. The synthesis and closing section on the design of robots specifically for more-than-human-justice helps here by including relationality, intersectionality and and contexts. 'Design justice' is something the book prompts me to carry forward (p.137).

NURSING -:- INFOTECH - worlds apart? Software testing

Another draft from over a decade ago ... duly revisited and updated:


https://www.statista.com/statistics/793628/worldwide-developer-survey-most-used-languages/

Reading up on Ruby and Rails and attending Scotland on Rails, I've been struck by the emphasis on testing. Testing in this context is about reliable software and building this into the 'product' from the outset. A book on Rails gets criticized because it leaves the chapter on 'Testing' until the end (even if the authors had their reasons - as they explained).

This take on testing is sufficient if (of course) it is appropriate and it is applied (as per the manual) to the application concerned. There are other more formal methods that extend to writing a specification for code which entails the use of formal specification languages such as Zed (as encountered in BA(Hons.) studies. This arises in situations were software is being developed for safety-critical situations. Clearly, robotic surgery, nuclear energy, and keeping an aircraft in the sky, take-off and landing are mission-critical. In the latter case a company is still dealing with life threatening loss of life that can follow, should the software system fail or more covertly introduce an error.

Reading about Rails, there are specific tests and these are provided as a result of scaffolding, a process whereby the bones of a web application are created within the Rails framework: with tests.

Rails creates a test directory for you as soon as you create a Rails project using bin/rails new application_name. If you list the contents of this directory then you will see:

$ ls -F test
application_system_test_case.rb  controllers/                     helpers/                         mailers/                         system/                          fixtures/                        integration/                     models/                          test_helper.rb
Source: https://guides.rubyonrails.org/testing.html

Rails uses a popular convention to organise and integrate the elements of a web application that includes a database, and dynamic interface. The approach is known as:

Models, Views and Controllers - MVC

MVC underpins several programming languages and frameworks. As displayed above, the tests that Rails creates have specific names and you can quickly see where they come from and how they encompass Rails (an essential property of course).

Today, I still wonder [ what's new! 😉 ] what is the equivalent to MVC in nursing? Models seems to fit! Over the years at many IT events, you can't help but reflect on nursing and its 'API' - application programming interface. Worryingly, in humanistic terms there is an instrumental potential in Hodges' model. If Nursing on Rails was a thing, what would the tests look like? Identity would be a feature, to demonstrate person-centredness, safety in medication and other treatment procedures. Is there a way to demonstrate the integration of care, and for a patient - the extent of holistic bandwidth? Of course, nursing comprises just a part of a clinical information system. It must be in sync in accord with other disciplines, medical and pharmacy and other multidisciplinary team members and yet ensure that 'nursing is visible'.

There is this thing - 'universal construction'

The problem of bugs in software is an ongoing problem across all IT industries. For application that are safety critical we are still reminded of the risk implications and consequences if bugs are software is not tested and bugs - errors identified and corrected.

Back in the 90s during BA(Joint Hons. Philosophy & Computing) studies, I was introduced to the formal specification language 'Z'. It was designed for definition, and modelling of computer software, working from specification to implementation, as per these images:

https://personalpages.bradley.edu/~young/CS592M120_OLD/handoutZed.pdf

https://personalpages.bradley.edu/~young/CS592M120_OLD/handoutZed.pdf

To be clear I've never worked as part of a software project and my 'tinkering' - Drupal, Pharo, online groups, hosting platform - reveals how the development stack and work processes have developed apace. The challenge is keeping up. Simultaneously, there is the sense of being on the bank of deep water; or, a vertiginous cliff:

A little learning is a dang’rous thing;
Drink deep, or taste not the Pierian spring:
There shallow draughts intoxicate the brain,
And drinking largely sobers us again.
Fir’d at first sight with what the Muse imparts,
In fearless youth we tempt the heights of arts,
While from the bounded level of our mind,
Short views we take, nor see the lengths behind,
But more advanc’d, behold with strange surprise
New, distant scenes of endless science rise! 
Pope. https://interestingliterature.com/2021/09/a-little-learning-is-a-dangerous-thing-meaning-analysis-origin/

 Acknowledging the need for an 'evidence-base' and theoretical underpinning the effort to 'push' Hodges' model forward is ongoing. Maths remains an alien territory to me, but the 'secret garden' is as tantalizing as ever. Over the years I have posted - with much overlap about:

  • maths
  • relation
  • logic
- and more recently:
  • isomorphism
  • category theory
  • and as previously posted - laws of form.
In an effort to get to grips with the above, I'm following various online videos, books and papers. Bartosz Milewski's videos, blog and publications are aimed at programmers, but are very interesting nonetheless. The first video provides an introduction to the motivation and philosophy of category theory. In another, Milewski refers to 'universal construction' on YouTube and in a blog post about 'Function Types'.

The 'universal' figures in healthcare too: universal health access, and universal health coverage appear to over-shadow 'universal health care'. The quality of 'universal' also creeps into assessment. Data gathering is not merely complete, it is comprehensive. It has to be, to contribute not just to a care plan, for one that is (supposedly) person-centred, with risks identified, strengths, weaknesses - needs, history, social network, and much more. The care plan informs and orchestrates the interventions; then evaluation follows. Are we delivering? What is the patient's (client's, carer's) level of satisfaction. Have care stages and actions been completed as per policy (in time!)? (More on this to follow later this year in light of UK mental health/illness news.)

So as I consider (wrestle with...) initial, and terminal objects, sets and categories … I can hopefully, especially with help, extend the number of posts tagged 'universal' here on W2tQ. In this vein, is Hodges' model a universal construction? There may not be a universal truth to reveal, but it will prove a marvellous learning journey.

'Design Thinking' in and out of four boxes...

In 2019 Charles Orton-Jones gave a brief (single page) account of design thinking in sales, with a description of its five components:

Empathise

Define the problem

Ideate

Prototype

Testing

Below, I've mapped each to Hodges' model (and in parallel):

INDIVIDUAL
|
INTERPERSONAL : SCIENCES
HUMANISTIC----------------------------------------------- MECHANISTIC
SOCIOLOGY : POLITICAL
|
  GROUP
Empathise
Ideate
Define the Problem
Prototype

Define the Problem
Prototype
Testing

Empathise
Ideate
Define the Problem
Prototype
Testing

Empathise
Ideate
Define the Problem
Prototype
Testing

 

There is often conceptual overlap and relationships when considering the most mundane, taken-for-granted of phenomena and events. This overlap increases rapidly with more complicated situations. This applies in the case of 'design thinking'. Ideate I take as a mental activity, but it is the flow and interplay of ideas: communication that counts. Empathy is imbued individually, but it is delivered and is realised in the social domain - as empathise suggests. Hopefully, from empathy with group rapport, trust, dignity and respect coherence will follow.

Politically, funding, team constraints, leadership may all influence defining the problem, prototyping and testing. Ideation is 'political' too. We forget this at our peril. Are we sure the protected characteristics have been factored in? You might also test the prototype against the original idea(s): thereby bringing in values. While this application is commercial sales, you are in personalised and specialised 'sales' in healthcare. 

While the above looks like duplication, the parallel approach can help assure the design thinking process as a whole. There is an open question here, but I'm sure despite the duplication and 'travel' to-and-fro within the model the structure helps instill some discipline with efficiency - economy of effort? The model acts as a marshalling (classification) yard.

As an example, this was brought home today on twitter, with a question about dealing with people who have a fear of needles. This may be children, a percentage of the general population and people with a learning disability. We see then how this overlap can be important. By default then working with the above design thinking + h2cm approach to achieve (variously) individualised, integrated, collaborative care then you might also be doing co-design and co-creation. Now that is sales ...!

The number of pages count (in a medical MOT)

Received in the post: an invitation.

For a medical MOT that would cost me £129 - which is a saving of £141.

I am informed that a competitor charges £564 for a "360" Health Assessment and £424 for an "Essential" Health Assessment.

Recently I spoke to someone who had major surgery and they remarked on the lack of assessment not on the medical side, but the social, especially in relation to discharge and the circumstances they would be returning to.

This example of apparent disinterest in a social assessment contrasts with practice in the past - several decades ago.

Apart from an awareness of  'silver clouds' and rose-tinted glasses what struck me was securing a sale by a manifest of paper:


The various blood tests that would be completed are detailed using medical terminology across four A4 pages. Depending on age there is a free respiratory screening too.

The following quotations (Alber, et al., 2017) state clearly the risks:
"There is a growing awareness among clinicians and health care scientists, that medical overuse comprises unnecessary health care lacking benefit for patients [3] or putting them at risk of harm outweighing a potential benefit [4]. Moreover, unnecessary medicine adds to rising health care expenditures [5] and a misallocation of scarce resources [6]. Asymptomatic individuals are at risk of being labelled as patients, causing anxiety and affecting their quality of life [7]." ...

"Moreover, in secondary prevention, risk factors are increasingly treated as diseases [8]. There is a tendency to screen asymptomatic populations at low risk and to label pre-diseases as manifest diseases [1]. Serum cholesterol levels are a good example of threshold lowering by shifting the boundary between health and disease [9]."


Over-treatment is also a problem in two critical and concurrent senses, as follows:

Developed health
systems

Need to transform to
health promoting, educational, preventive,
self-caring systems.
Developing health
systems

Need to prevent the inheritance of commodified health care and over-treatment.*


Alber et al. also provide a useful diagram preceded with more background:
"In primary care, the “quaternary prevention concept” [11] was introduced (see Fig. 1 ) in order to protect individuals from unnecessary investigations and treatment. Quaternary prevention is a “new term for an old concept: first, do not harm” [12]. It refers to actions “taken to identify [a] patient at risk of overmedicalisation [= in the sense of medical overuse, author’s note], to protect him from new medical invasion, and to suggest to him interventions, which are ethically acceptable” [13]."

PrimaryCare. 2010;10:350–4, and [12] Jamoulle M. Quaternary prevention, an answer of family doctors to overmedicalization. Int J Health Policy Manag. 2015;4:61–4

Without being dismissive of screening and its relation to health and well-being, I have removed myself from this particular mailing list.

At some point I must really apply Hodges' model to this discussion. The model is ideally suited to navigating and arguing this debate; from self-care, primary care, prevention, population and global health. I have posted previously about the damaging ideal of the comprehensive health record and the way that records seem oriented to assessment and risk reduction with outcomes and relapse prevention an after-thought. This defensiveness is critical for public safety, professionalism and accountability, but as a thread on twitter shows it can have a negative impact too.


*There is an additional confounding factor at work in developing nations, the incursion of digital technologies from outside.

Drupal musings 11: Git up and go ...

For more than I care to remember I've recognised that version control is an essential facet of software development. During this time though I've not had a need for version control. Renewed awareness of this tool was inevitable as I decided to identify a content management system [CMS], which brought me to Drupal and I simultaneously also discovered Ruby.

Now I'm pleased that over the past three years I did not commit to Concurrent Versions System [CVS] as used by the Drupal community. I listened to talks, downloaded, and tinkered, but now - the (old) news that Drupal 8 development will use GIT.

So, for me it is time to jump on-board with git for version control: a book and presentations next week.

It's not that I'll be contributing to D8, it just makes sense to git up to speed on this (sorry!). I've been through the program and created my schedule for next week in Copenhagen. There is so much to look forward to!

Version control is one thing, having the need and discipline for testing is another ...
