  1. Series of "Did You Know" videos

    Here's a collection of pointers to short "Did You Know" videos from the Developer Advocates, highlighting small but interesting and useful aspects of various SAP tech tools, frameworks and products.

  2. Modifying queries, replacing the WHERE clause

    Here's a quick post to explain how to modify existing query objects in CAP, specifically using the CAP Node.js cds.ql API.

  3. Path expressions, nested projections, aggregations and expressions in queries with CQL and CXL in CAP

    A brief exploration of some of the features of CAP's powerful query and expression languages, inspired by our journey into CXL in the current Hands-on SAP Dev series.

  4. OData Deep Dive rewrite in the open

    I'm refreshing the content of the OData Deep Dive series of tutorials, in the open.

  5. Modules, modularity & reuse in CDS models - part 5 - digging into @capire/common

    In this post I look at various mechanisms that @capire/common has that makes it "active" as a reuse package.

  6. Constraints, expressions and axioms in action

    In this blog post I meditate on how declarative constraints are realised in CAP, using the power of the underlying database.

  7. Modules, modularity & reuse in CDS models - part 4 - from passive to active with @capire/common

    Starting with a simple use of the published @qmacro/common reuse module, I then turn to @capire/common for a first look at what I call an "active" reuse module.

  8. Modules, modularity & reuse in CDS models - part 3 - publishing the simple reuse package

    Taking the simple passive reuse package created in part 2, I now publish it to the NPM registry which is part of GitHub Packages.

  9. Modules, modularity & reuse in CDS models - part 2 - creating a simple reuse package

    Following on from part 1 in this series, I take a step back and look at the fundamentals of creating and working with a module, locally in this part, using the NPM workspace concept.

  10. Why I use services.cds in simple CDS model examples

    The services.cds filename is special, which is why I make use of it.

  11. Modules, modularity & reuse in CDS models

    An overview of the blog posts in the series "Modules, modularity & reuse in CDS models".

  12. Modules, modularity & reuse in CDS models - part 1 - an introduction

    In this first post of a new series I look at the using directive in CDS modelling, and how NPM modules can be fundamental building blocks in modularity and reuse.

  13. A new Hands-on SAP Dev mini-series on the core expression language in CDS

    Hands-on SAP Dev is back soon, kicking off in January with a new mini-series on CAP, specifically on CXL, the core expression language in the CDS family.

  14. A simple exploration of status transition flows in CAP

    In this post I explore the new Status-Transition Flows in CAP with a simple example.

    A brief note-to-self after digging in to some simple constructs in CDS modelling.

  16. Hands-on domain modelling with CAP's CDS at UKISUG Connect

    A quick overview of the hands-on workshop I'll be running at UKISUG Connect this year.

  17. Quiet cds test output - two ways

    Reducing CAP server log output during tests, in two different ways, via a profile encapsulated set of log level configurations, or via the new cds test command.

  18. Modelling contained-in relationships with compositions in CDS

    A short study of the features of CDS for modelling classic contained-in relationships, with a focus on the details, and a lean towards anonymous aspects.

  19. Using @capire modules from GitHub Packages

    Here's how to access and use the @capire namespaced modules that reside in the NPM registry which is part of GitHub Packages.

  20. CDS source formatting and readability

    Embracing a modern approach to source code formatting for human-centric modelling in CAP

  21. Upcoming talks in autumn 2025

    I'm writing this mostly to organise myself and get my preparations in order!

  22. Auto formatting extensionless Bash scripts in Neovim

    Here's what I did to make the combination of the Bash language server and shfmt work with Editorconfig settings for Bash script files that don't have extensions.

  23. Neovim configuration for file and module navigation in CDS models

    In this post I describe how I extended my Lua-based Neovim configuration for CDS filetypes to improve navigation to referenced files and modules.

  24. Excluding specific diagnostics in Neovim

    Here's what I did to be able to filter out certain diagnostic messages in Neovim.

  25. A reCAP intro to the cds REPL

    Here's a summary of my talk on the cds REPL at this year's reCAP event.

  26. A modern and clean Neovim setup for CAP Node.js - configuration and diagnostics

    In this post I describe my re-worked basic setup for working with CAP Node.js in Neovim, focusing on the configuration and digging into the LSP based diagnostic facilities.

  27. Editing Markdown in a Neovim environment

    Here are some notes I made when digging into my tools for editing Markdown source.

  28. Point free coding and function composition

    In this post I explore and show examples of the concepts of point free coding, of chains of functions through which data flows, and of function composition.

  29. Adjusting the preview width in Telescope's horizontal picker

    Here's how I adjusted the width of the preview window in Telescope's horizontal picker.

  30. FP, function chains and CAP model loading

    Understanding functional programming approaches, no matter how trivial, can help in other areas. Here I explain how being comfortable with function chains helped in working out why a required (but unused) service was being loaded into the overall CDS model in a CAP project.

  31. Array.prototype.reduce and the optional initial value

    Today I learned about the subtlety of the optional initialValue parameter for the Array prototype's reduce method in JavaScript.

  32. Functional programming resources

    I've created quite a bit of FP related content in the past but it's somewhat scattered across different platforms and in different formats and I can't remember what or where it all is. So this is a meta post in which I point to all the resources (that I can remember that) I've created on the topic.

  33. How I run executables in containers

    Here's a quick post explaining how I might typically containerise an executable. This is in the context of my aim to not "pollute" my base OS (at the bare metal level) with any installs, as far as I can, as well as to remain platform independent and abstract.

  34. Level up your CAP skills by learning how to use the cds REPL

    These are notes I wrote for my talk at SAP Inside Track Madrid on 20 March 2025. I wrote them partly to think about what I wanted to say, and partly to share the info in written form too. Note that the idea is to introduce the concepts and show some basic examples for cds REPL "initiates". Nothing too exotic.

  35. Migrating GitHub issue based URL bookmarks to wallabag

    In this post I outline how I migrated my collection of reading list bookmarks, stored as issues in a GitHub repo, to wallabag which I'm now self-hosting.

  276. Monday morning thoughts: looking back and forwards

    I look back on the posts in this series, reflect upon the journey we've made, and think about what 2019 might hold for us.

  277. Monday morning thoughts: digging deeper

    I think about the tools we use in our day-to-day activities, the feeling I have that I'm just scratching the surface with regards to their capabilities, and what I plan to do about it in 2019.

  278. Monday morning thoughts: indirect influence

    On how our work can directly and even indirectly influence those that come after us, and about what this means for how we should act.

  279. Monday morning thoughts: learning media and mechanisms

    I think about the different ways I learn, and wonder how that translates to how we learn in the SAP developer ecosphere.

  280. Monday morning thoughts: rethinking like the web

    I revisit some principles that help us "think like the web" and think about them in the context of today's SAP technology landscape and community.

  281. Monday morning thoughts: longevity and loose coupling

    I think about the importance of core technologies, and how the arrival of functions-as-a-service might be merely the next incarnation of an idea that's existed for a while.

  282. Monday morning thoughts: on starting blogging

    On what made me start blogging, and on the reasons to start blogging that might resonate with you, if you've not yet made that step.

  283. Monday morning thoughts: exploring reuse

    I think about reuse and extension, in the context of the Application Programming Model for SAP Cloud Platform, and mindful of Björn Goerke's SAP TechEd 2018 keynote message in Barcelona - "keep the core clean".

  284. Monday morning thoughts: dynamic language

    Musings on a particular function definition in JavaScript, and how it represents beauty and practicality in equal measure.

  285. Set up VS Code on Chrome OS for local Application Programming Model development

  286. Monday morning thoughts: big school and community

    On my experience going from primary school to secondary school - "big school", how that parallels our collective move from on-prem to the cloud, and how the community is more important than ever in this transition.

  287. SAP Cloud Application Programming Model (CAP) - start here

  288. Monday morning thoughts: more on ABAP in the cloud

    Following a previous post on the subject, I think a bit more about the SAP Cloud Platform ABAP Environment, inspired by the conversations around the subject at SAP TechEd in Las Vegas last week.

  289. Monday morning thoughts: impostor syndrome

    On the impostor syndrome, how it relates to me, and one of the possible causes.

  290. Monday morning thoughts: growth is upwards

    In this post, I think about how we grow, how we improve ourselves by adding to our knowledge and experience, and consider that our growth is sometimes uphill but almost always rewarding.

  291. Monday morning thoughts: Workflow Forms and the definition of a developer

    I think briefly about the definition of a developer, and in that context look at the advent of Workflow Forms, a major new addition to the functionality of the Workflow service on SAP Cloud Platform.

  292. Monday morning thoughts: ABAP in the cloud

    I think about the new SAP Cloud Platform ABAP Environment, what it is, what it isn't, and why I think it's a great move.

  293. My take on Wired's Google & URLs article

  294. Monday morning thoughts: considering GraphQL

    On GraphQL, and its relationship with existing ideas for managing data and structured exposure to that data over a wire protocol.

  295. Monday morning thoughts: a good blog post

    What makes a good blog post, and also what writing such a post does for the author, too.

  296. Monday morning thoughts: OData

    I think about OData, in particular where it came from and why it looks and acts like it does. I also consider why I think it was a good protocol for an organisation like SAP to embrace.

  297. Monday morning thoughts: the cloud is the computer

    I think about what the future of programming in an enterprise environment might look like, and realise that it makes sense to consider that the cloud itself is the new computer.

  298. Monday morning thoughts: mainframes and message documentation

    I think about mainframes and a message documentation aspect from the mainframe world that, while originally proprietary, is a big plus for operators and developers alike and something I'd love to see return.

  299. SAP CodeTalk sessions

  300. Monday morning thoughts: local http servers and containerisation

    I look back on an idea surfaced by a hero of mine, and think about how that idea laid the path for today's containerisation initiatives.

  301. Monday morning thoughts: what not how

    In this post, I think about how we program, about the way we describe what it is that we want the computer to do for us, and look at what has become for me the canonical example of the difference between 'what' and 'how'.

  302. Monday morning thoughts: abstraction

    I think about abstraction, the power and facility it affords, and consider CDS as one example of a modern abstraction language.

  303. Monday morning thoughts: curiosity and understanding

    I think about how curiosity can lead to a better understanding of things, and give a specific example concerning CDS and the new Application Programming Model for SAP Cloud Platform.

  304. Monday morning thoughts: developers and advocacy

    I think about what it means to me to be a part of the Developer Relations team, and talk a bit about evangelism, outreach and advocacy.

  305. Monday morning thoughts: programming models

    I think about the idea of the programming model and consider the occurrence of such over the recent years in the SAP development ecosphere.

  306. Interview with Rui Nogueira on the new Application Programming Model for SAP Cloud Platform

  307. Monday morning thoughts: community engagement

    I think about some of the basic ingredients of a good online community, and describe what I'm going to try to do to engage more with the SAP Community.

  308. Monday morning thoughts: Core Data Services

    What Core Data Services (CDS) is, what it does, and why we should make it a priority to learn more about.

  309. Monday morning thoughts: the learning continuum

    I contemplate the idea of the learning continuum, and think about the fact that we're all learning together, which is a good thing.

  310. Monday morning thoughts: programmers and identity

    On how some programmers identify strongly with a particular language, consider the meanings of 'programmer', 'coder' and 'developer', and what it means for us as the SAP enterprise programming landscape changes.

  311. Collaboration tools

  312. The Business Rules service - overview and getting started

  313. Monday morning thoughts: milestones

    I look back at changes and developments that I consider milestones in SAP's technology history, and muse on some of the developments today that we'll consider milestones in the future.

  314. Monday morning thoughts: functions - what functions?

    Musings on the concept of functions-as-a-service, what it means, and what it's good for.

  315. Balancing features with simplicity

  316. Monday morning thoughts: containers and silence

    On the silence of workstations and what that represents to me, and the new ability to look at maintaining software and services in a completely different way - via containers.

  317. Monday morning thoughts: editors and editing

    I look at how the editor environments that we come across in our daily work are different, and, as those differences might grow and expand as we become cloud native, how we bridge the contrast in facilities with core obsessions such as correct indentation and whitespace.

  318. Monday morning thoughts: debugging approach and Greasemonkey revival

  319. Monday morning thoughts: upload / download in a cloud native world

    On how our modus operandi is often at odds with the true nature of cloud computing.

  320. Monday morning thoughts: a cloud native smell

    On the importance and design of URLs, and the opacity of cattle vs the individuality of pets.

  340. Debugging SAP Fiori apps - the fifth "D"

    It's all very well designing and building a delightful Fiori app. But what about the long tail - supporting that app through its lifetime, with fixes and changes that come along? There's a fifth "D" to the SAP Fiori development mantra, and that "D" is for "Debugging".

  593. SDN, Blogging, and Planet SAP

  613. The meaning of LIFETIME_RC

    Last week, during some preparation for my talk at TechEd on Thursday this week, I’d been wondering about something in the ICF that hadn’t seemed quite right.

  614. SAP TechEd first day - notes from Munich

    Well, after a nightmare getting here (V-Bird, the airline I was booked with, went bust) I’m now in Munich at a decidedly disconnected TechEd 04 (more on the disconnected misery later).

  615. SAP TechEd here I come ... with session slides!

    SAP TechEd is looming large, and this year it's in Munich. (If you’re not in Europe, then SAP are holding TechEd events in Bangalore, Tokyo, and San Diego too).

  616. The integration irony of SAP's technology directions

    I’ve finally realised what it is that’s been bugging me about the new arena of SAP technology.

  620. TechEd talk winners - congrats

    Congratulations to the three TechEd talk winners Luke, Jayakumar and Andreas.

  621. Forget SOAP - build real web services with the ICF

    I don’t like getting into a lather when it comes to data and function integration. Rather than using SOAP, I prefer real web services, built with HTTP.

  622. Real Web Services with REST and ICF

    This piece has become somewhat famous (or infamous) in SAP tech circles, for the approach it took and the claims it made. I'm happy to say that REST won out and that those that tried to denounce me ... failed :-)

  628. FOSDEM, and small OSS Notes Browser Hack

    Tomorrow morning I'm off to Brussels for FOSDEM - the Free and Open Source Software Developers' Meeting.

  629. FOSDEM and Brussels, here I come!

    I’ve been umming and arring over conferences this year.

  630. Hawo's Queen of Grain Mills

    I've been baking bread now for quite a while now. The bread baking bug first got ahold of me when visiting friends. They had a bread making machine – something that you put all the basic ingredients into, hit a button, and presto. Naturally we bought one soon after, and I was, well, "hooked".
