Hands-on SAP dev with qmacro – new live stream series

I live stream on a regular basis, and have been doing so since early 2019, first on Twitch, and now on YouTube. I have an approximately weekly schedule, with episodes on SAP development topics. The show is called “Hands-on SAP dev with qmacro” and you can join to watch and take part live on my YouTube channel, usually on Fridays. This post tells you what else you might need to know. 

If you’re looking for information on the upcoming episode, jump down to the Upcoming Episode section below.

If you’re looking for the recordings of the live streams, jump down to the Catch the replays section below.

This post has multiple sections – here are quick links to them all: Background | Live streaming | The schedule | How to watch | Catch the replaysUpcoming episode | Updates.

One subject I’ve been thinking about for a while, especially in the context of my Monday morning thoughts series last year (in particular the learning continuum, growth is upwards and learning media and mechanisms posts) is how I take on new information.

One of the ways is to watch videos, and for me that is a medium that is easy and enjoyable to consume.

A wonderful bonus for me is the side effect of getting inside the heads of developers, learning, on a high level, how they operate, and noticing, on a low level, how they work on a day to day basis. On many occasions, the things I’ve learned have been serendipitous and only partially connected to the subject at hand. How a developer goes about editing, what tools they use, and what workflows they employ, deliberate or otherwise.

Live streaming

One of the consumption styles in this vein is to watch live streams, where folks work on stuff, figuring things out, building up solutions piece by piece, or sharing knowledge or experience in specific areas … in full view of an audience who are present there with that host, over the Internet. Moreover, in the live streams I’ve joined, it’s two-way. The viewers can interact with each other and with the host, via chat and other mechanisms.

It’s a fascinating idea, and one that caught my imagination last year, so much so that I thought I’d give it a try.

The schedule

There are two streaming schedules – the regular weekly Friday slot and the occasional fortnightly Wednesday slot.

The regular weekly Friday slot

I stream regularly once a week on Fridays. It’s a one hour slot. I’m a morning person, which is one of the reasons the regular streaming slot is at 0800 UTC+0 (UK time).

That means the main weekly stream schedule looks like this going east around the globe:

The regular Friday slot starting at 0800 BST (Manchester):

Start time Time Zone Example City
0800 BST Manchester
0900 CEST Walldorf
1230 IST Bengaluru
1700 AEST Sydney

The fortnightly Wednesday slot

I also stream approximately every fortnight (every 2 weeks), midweek on Wednesdays. This slot is in the afternoon, Manchester time, so I can catch US folks in their timezones.

The fortnightly Wednesday slot starting at 1500 BST (Manchester):

Start time Time Zone Example City
0900 CDT Chicago
1500 BST Manchester
1600 CEST Walldorf
1930 IST Bengaluru

Of course, regardless of time, you are all welcome to join. But there’s no way I can cover all timezones around the globe with a single slot, so I’m going to make sure each stream is are recorded for replay at a later date too – see the replays section elsewhere in this post.

How to watch

I used to stream on Twitch (in 2019), but I now stream on YouTube. All you need to do is visit my channel and subscribe (so you get updates and notifications):

If you’re signed in to YouTube when you join a live stream, you’ll be able to chat and take part in the live stream discussions, which is great! 

Catch the replays

If you missed a live episode, you can watch the recording, which will be available on my channel pretty much straight after the the live episode finishes.

Each recording is then also available on the SAP Developers channel organised in a playlist Hands-on SAP dev with qmacro – by the way, don’t forget to subscribe to this channel too!

Annotated links: For each recording on YouTube, there will be annotated hh:mm:ss links so you can jump straight to the part you’re looking for. One annotations blog post per episode – and the links are in the rightmost column in the table. This tweet shows an example of how you might use the annotated links feature.

Ep.0 – Getting our feet wet

In this initial episode of the “Hands-on SAP dev with qmacro” series, we take a brief look at what using SAP’s Cloud Application Programming Model in a Node.js context means for us JavaScript developers, and warm our brains up by solving some puzzles with a bit of ES6 flavoured code (with some functional aspects thrown in for good measure).

Ep.1 – Setting up for the Node.js flavoured version of SAP’s Cloud Application Programming Model

While we warmed our grey matter up in the previous episode, in this episode we set up what we need to build with the Node.js (JavaScript) flavoured version of SAP’s Cloud Application Programming Model (CAPM). This version allows us to build locally, with tools on our own machines, so that’s what we’ll be doing.

Therefore, we use the SAP NPM registry to find & install the command line tool ‘cds’ that we can use to generate and manage Node.js based CAPM projects and also install the CDS language support for the VS Code editor, which comes in the form of an VS Code extension. Then we set up our Cloud Foundry environment on SAP Cloud Platform and install the ‘cf’ command line tool which we can use to interact with that environment.

Ep.2 – Starting to build a bookshop backend service with CAPM

In the previous episode we set up our tools and development environment ready for some SAP Cloud Application Programming Model (CAPM) action of the Node.js (JavaScript) flavour. So now we’re ready to start exploring our first data and service definitions in the language of CAPM, i.e. CDS (Core Data & Services).

We follow the “Create a Business Service with Node.js using Visual Studio Code” tutorial on the SAP Developers tutorial navigator and start to explore what CAPM and CDS can do for us.

Ep.8 – Using Axios, ES6, promises & pure functions to grab data

In Episode 6 we set out creating our mini Northwind service, called Northbreeze, and started to write some code to grab the Northwind data, exploring Axios as an HTTP client library that supports promises and (therefore) dot chaining. In this episode we continue on towards completing this code to produce CSV files as input to our CAP model, exploring pure functions along the way.

Ep.12 – Exploring and understanding parts of @sap/cds JS – code & style

I had an itch to scratch, in that I wanted to be able to filter out columns in CSV files. In this episode we take a look at some of the JavaScript within the @sap/cds module – what it offers and how it’s written. We then see how some of that was useful in building a simple CSV filter mechanism.

Ep.13 – Stdio-ifying the CSV filter mechanism

In the previous episode (Ep.12) we looked at a simple CSV filter utility. In this episode we improve it by giving it the ability to read from STDIN and write to STDOUT so it plays nicely in pipeline contexts. Then we’ll be ready to use it to finalise our data for our CAP based “Northbreeze” service.

  • This is cool! I’ve been thinking about doing some live streaming of architecture conversations and diagrams, and twitch seemed a great platform. I’ll be curious to see how you get on.

  • Hi DJ. I just watched the stream for the first time this morning and I only have one word: AMAZING! Digging into what’s behind the tutorials is super interesting and useful, I really like this format and I can’t wait for the next stream!

    • Hey Pierre, first of all thanks so much for joining the live stream this morning and participating too, I really appreciate it. And thanks also for the feedback, that makes me very happy that you found this interesting and useful. Looking forward to seeing you join the next episode!


  • Hi DJ,

    Not sure when you can read this comment, but you may have floated the idea how twitch is helpful/useful in your most recent episode (August 23rd) and that got me thinking and respond here.

    How about making mp4 files downloadable somewhere, including here or on wiki, assuming both technical and privacy issues are taken care of?

    most of all, thank you for providing great content and driving the SAP ecosystem interaction.

    cheers, gm

    • Hi Gregory, that’s something that I try to do, albeit indirectly. Here’s the process, in a nutshell:

      1. broadcast episodes live on Twitch ->
      2. recordings of those episodes immediately available on Twitch –,
      3. a pointer is added to this post to each episode’s details as well, including a link to the video, in the ‘Catch the replays’ section ->
      4. in the meantime, the recordings also exist locally to me as MP4 files
      5. I then annotate those MP4 recordings to create blog posts, which I publish, and the recordings themselves are then uploaded to YouTube to a playlist in the SAP Developers channel ->
      6. the links in the ‘Catch the replays’ section of this post are then updated with the YouTube video link and the annotation blog post link

      The key thing to realise that throughout this process, you can download the videos whenever you want, either from Twitch or from YouTube, with the youtube-dl utility program.

      Hope that helps – share & enjoy!


  • DJ,

    indirect is fine as long as the source is open and if i end up using the shareware i will also pay for it. cloud as it is, whether AWS, GCP, or any other, is not always available, so personal backups help to recover from the disasters.

    thank you for responding with a little bit of home work, gm


    • Cheers Greg. Note – youtube-dl is public domain software, not shareware. You can donate of course, if you wish, via the link.
