  • Worknotes - November 2020

    20 November 2020

    I taught at Hyper Island this year for my fourth year now, as Industry Leader for the Digital Technologies module of their part-time Digital Management MA.

    At the end of the course, I give a paper where I talk about personal process and practice. It’s a bit left-of-centre: not so much Best Practice, as Things I Have Found Useful.

    I always tweak and rework the course a little each year. This year, I came to this paper, and found myself stuck. In it, I talked about the value of personal documentation: READMEs in every project and code directory, so you can always pick up a thread after months away; weeknotes as a ritual and way of evaluating work. I talked about the value of colocation - why I prefer studios to offices, why the right people together in the right space is such a winner for work, and how precious a Good Room can be. And at the end, I self-indulgently talk about the value of reading fiction

    At the beginning of September, I sat looking at the deck, and realised:

    I am doing none of that right now.

    Weeknotes, as you can tell, have fallen by the wayside. I’m Working From Home If Possible (and it is possible), not going up to my studio space. I’m working on projects on a succession of videoconferencing tools, all with their own quirks, and spending longer in my study than I’d like. I’m not reading as much fiction as I’d like.

    I felt like I’d be a hypocrite to say these things to students.

    In the end, I said it all anyway, dropping in a quick “recordscratch” sound effect to call myself on my own shortcomings, and to talk about the difficulty of espousing studio culture in an airborne pandemic.

    It went down well, but it also turned out to be not as foolish an idea as I thought. By acknowledging the fragility of ideals in the face of reality, we could explore why I was recommending those practices in the first place. By challenging myself as to why I wasn’t following my own advice, I could explore what the point of that advice might have been.

    The fact that I wasn’t writing at the moment didn’t mean that writing wasn’t a thing to recommend. It possibly meant that weekly notes were not quite serving a purpose now. After all, if I was busy, and getting the work done, and if the thing that fell by the wayside was talking about that, I might have to live with it, and work out how to change it.

    For now, weekly notes might disappear for a bit. I’ll work out what replaces them in due course.

    Meanwhile, let’s see where things are right now, in the middle of November 2020, and what’s happened in the past four months.


    I delivered Easington in early September. I’d written about the project here previously; most notably, in this post on props and prototypes.

    But then writing about it dried up. This was partly because having worked out what the job was, I mainly had to work on delivering that. Having done bunch of Thinking About Stuff, much of the work was Making Stuff and Explaining Stuff (sometimes both at once). There often wasn’t much more I could easily say here other than “yep, getting on with things“.

    If you’ve read these notes for a while, you’ll know I’ve got all manner of ways of saying “yep, getting on with things“, but 2020 appeared to exhaust them.

    It was also challenging because Easington was under an NDA, and the specifics of the project meant there was almost nothing I could say without revealing things my NDA forbids me from revealing. And given that, I was largely quite quiet.

    What I can say:

    Easington was a fourteen-week R&D project for Google AIUX, who work at exactly that intersection: the user experience of future AI-driven products. I worked closely with design colleagues inside AIUX, especially in London, but also spoke to researchers and topic experts from internal teams around the world. It was challenging and rewarding in equal measure. I’m proud of what we delivered.

    It was also a project that almost directly mapped to what I laid out in March, when I wrote about what I do, before Everything Changed, and it was hugely rewarding to confirm that yes, that’s an excellent summation of my sweetspot.


    I went on vacation in the UK for two weeks after Easington ended. This was long-planned, and not an emergency “COVID holiday”. But I was very fortunate to be able to take that time off, and to do so in a safe and sensible way.

    Teaching at Hyper Island

    As mentioned above, I taught at Hyper again. Normally, this takes place in December and January of a year. However, as we were going to be teaching remotely this year, they decided to move my module to be the first the students took, not the second, and we delivered this in September and early October.

    I reworked a lot of the material, and will write more about the specific nature of that reworking in the future, because I learned a lot about delivering material online.

    In broad terms, we made everything shorter, denser, and with more breaks - lectures became more like “episodes”, nothing over 25m without a break. We also ran shorter days - 11-5pm, rather than 9-6pm, as we were all on Zoom for most of the day. In that reworking and condensation, I think I got to some of the best versions of those talks; condensation, and the clarity videochat requires, really helped to focus things.

    I also coached the teams on their client project, and this time around it was exciting to see them embark on their first project, with no idea of where they could go, or what they could get done, in such a short space of time. Everybody’s pitches came out great, and it was a delight to meet so many new people. I say something similar each year, but I say it anyway, because it’s true.

    I was also grateful to colleagues and peers we could invite in as guest speakers - to everyone who came, thank you.

    A change of venue

    As mentioned, I’m not really using my studio space at all at the minute: there’s just no reason to be commuting. By September, I realised that this was going to be a longer-term change. I’m lucky enough to have a private workspace at home, and with some rearrangement, it’d be suitable as a place to work from. So, with some sadness, I handed in my notice at Makerversity. I’ve been at MV for almost exactly five years now, and was greatly enjoying the new setup in Vault 7. But right now, I cannot justify the expenditure, given how little I need to be there. And so I’m going to say goodbye, and work from the home office for a bit. Not how I ever imagined I’d leave MV, and the excellent Somerset House community, but there you go.

    A return to CaptionHub

    Finally, in October, I returned to a three-month contract with CaptionHub. They had some extra work coming up on their slate and an extra pair of hands that knew the project would be welcome to help deliver it. Given the uncertain nature of 2020 - and, to be honest, 2021 - it felt like a no-brainer to take a three-month contract with them.

    In one sense, this project is ‘just’ a software development gig. But it’s a particular kind of engineering I quite like: a careful, almost standalone set of features that need as much planning as they do implementation. I’ve been focusing on swapping out some of the underlying premises in the code, in order to support future features, which has led to a lot of diagrams and thinking before embarking on a careful switch from one shape of the world to another. I have described this as indianajonesing, in reference to the opening of Raiders of the Lost Ark (and I should note, this is not my metaphor - I just cannot remember where I got it from). In our case, I’m swapping one set of code for another, and making sure nobody notices the changeover, and no-one gets squished by a giant boulder.

    It’s going well, although it takes a lot of my brain and concentration (which is not quite in the supply it was in 2019). That often means there’s not space for much else at week’s end (I’m taking Fridays as days for personal work). But good work, with a lovely, thoughtful team, is highly appreciated right now.

    Appreciation is the right note to end on. I’ve been very lucky to be able to take on all these projects this year, in a time when work hasn’t necessarily been easy for everyone, and I’m always careful to acknowledge that when talking about my own practice.

    Right now, I wanted to acknowledge where everything was, and share what I could about the last few months. I imagine worknotes continuing in perhaps a less frequent format for the coming weeks and months, whilst I get back in the habit, and maybe find new ways to share my practice.

    What I concluded, talking to the students, was not the frequency, but the act. Some writing beats no writing.

    And hence: some writing.

  • I wrapped up phase two of Easington. We completed the beta of our interactive game-like thing that we built to explain the output of that phase. The prototype evolved a lot during the phase. Probably the best thing that happened as it progressed was that things I’d initially described in text were extracted to state. That is to say, we made it more gamelike: rather than describing other possible outcomes of an action, why not find a way of letting the user alter the state of the world, and then see what happens when they repeat the action?

    It sounds obvious when I write it down, but when I’m head down in the code, it is sometimes hard to have that high-level picture. This is one of the values of weeknotes: acknowledging what I missed, and writing it down so I don’t forget. Making the prototype more interactive - adding new interactions, and making it respond more richly to them, turned out to be the right answer every time. Something to remember for the future.

    This phase of the project has had me thinking a lot about propmaking, and its relationship to protoyping.

    Props in films aren’t just one thing. Think about a prop like, say, a lightsaber from Star Wars. A single prop lightsaber will likely exist in several forms, including:

    • a “hero” prop, that’s seen in close dramatic scenes. Made of realistic materials (metal, plastic, wood), full size, detailed. Something an actor can act with, and respond to. Something that will look good on camera.
    • perhaps: further hero props in different states: with the blade extended and retracted, for instance, or “damaged” and “undamaged”.
    • perhaps a separate functional hero prop for specific purposes. Imagine a close-up scene where we see the hero dismantling their lightsaber and repairing it: that “dismantalable” prop might be entirely different to the hero prop seen most of the time. (It might even be a partial prop - just the parts you can see in shot, and extra things to make it work also attached)
    • stunt props. These look almost identical to hero props, but are usually made entirely of foam rubber, and cast from the hero prop. These are used, as the name suggests, for stunts, where the object might be bashed around, or come into contact with an actor at velocity. They also end up being used for scenes where there’s any rough handling of a prop that might damage the prop itself - being thrown, or dropped, for instance. And frequently rubber props will used for background action, made en masse to give to extras, or used when the hero prop isn’t strictly necessary - when the lightsaber is hanging from the hero’s belt in a scene where it’s not really used, for instance.
    • once upon a time, props might have existed as scale models - a miniature lightsaber on a stop-motion puppet, for instance. Scale models tend to be more common for large objects, like vehicles or buildings.
    • the modern equivalent of a scale model prop is a CG version of it, to be used in computer-generated visual effects. The prop has a digital double, perhaps made from a 3D scan of the object.

    And for some of those props, on a large film shoot, there will be duplicates and spares.

    I’ve been thinking about the way one prop exists in multiple forms, and the different roles they all serve, because of all the different kinds of prototype I’ve built so far on Easington.

    So far, we’ve made real working code and tools (out of Python/Javascript and Docker/Cloud Run, as well as modern front-end web stuff); an interactive, explorable prototype pocket world; browser-based prototype UIs; clickable prototypes in Figma; and sound and video prototypes made out of samples, synthesis, and video in tools like Ableton Live and Hitfilm.

    And all of those prototypes are very, very different.

    • Our working code makes a useful point about the current state of things, and lets other people explore the idea. But it’s not in any way production ready, and it falls apart a little if you don’t use it the way it’s intended. That’s our close-up, working-for-one-task prop.
    • Our clickable mockups are like stunt props: they look highly convincing, fulfill a hugely important role, are highly robust, but the second you touch one you’ll discover it’s fake.
    • Our video and audio demos are a lot like CG: entirely convincing, we can do whatever we want with them, but 100% fake - and not even interactive.
    • Our interactive gamelike is a bit like a scale model: it has not just look/feel but logic as well, albeit in a highly constrained and limited way. It makes sense in its own little pocket universe.

    Like props, none of these are exactly ‘real’, and none of them work outside the world of the project. But they all serve useful purposes, and like all the different prop lightsabers, they all work together to tell our story. Our scale models, clickable mockups and VFX are made convincing by the fact we’ve also shown genuine, working code, but in a rougher form. And they wouldn’t have the same impact if we didn’t have that “close-up” prototype.

    The mockups and scale models help us invent and imagine, and help people using them imagine how the fragile working code might feel in the world, and in the near future.

    The other thing I find useful about enumerating the different types of prototype we’re making is it helps me understand what their individual value is - and when they might be considered “done”. Because they’re all fulfilling different roles, they have different completion criteria. Some need to look very good; some need to function correctly; some need to be somewhere in the middle. Understanding what the prototype is trying to achieve in terms of its role, not just its functionality, helps me think about the right material to build it out of, the right level of detail to furnish it with, and when to put it down and move onto a different kind of prototype.

  • Weeks 389-390

    29 June 2020

    Another couple of weeks with my head down on Easington.

    It’s a challenging project to talk about, because of NDAs. But that’s somewhat the point of weeknotes: noting not only what I did, but how, and why. The job isn’t to share the details of what I was up to: it’s to share the parts I felt worth sharing as insights into process, or thought, or for me to remember in the future.

    The project has moved to a new section of exploration, which is involving less prototyping of working code, and is more about explaining ideas, possibilities, and illustrating processes. Some of this fortnight’s work has been finding ways to do this that Aren’t Decks.

    Slide decks aren’t inherently dreadful. They have a lot to recommend themselves as formats to encapsulate and preserve information. They combine images and words relatively well, they are often terser than long prose documents, and emerge not as a ‘primary’ artefact - “here is my research paper” - but as synthesis. That means they’ve gone through the mill a few times and are condensed, compact versions of an idea.

    But. The “distribution deck” is still very different to a presented deck - or even a writer walking you through the deck they will later distribute. Decks are relentlessly linear, which makes conveying ideas that may only ‘click’ after prolonged exposure challenging.

    A good narrative reinforces itself when it ‘clicks’ into place. The ‘aha’ moment for a reader shouldn’t be a single moment of discovery; it should also reverberate through each step of a narrative, revealing how they set up this particular ending. That may sound flowery and poetic, but it’s often true of research or design presentations: everything up to the reveal is preparing you for it. Of course, you are then either carried forward by the speaker without a chance to revisit it… or have to flick backwards through the deck.

    This is not really how thinking works. The moment something clicks may be different for different readers, dependent on how they think, where their attention is, what ways of transferring knowledge work best for them. Less linear formats let people pace their discoveries, repeat segments in more natural manners than ‘rewinding a tape’, and make re-examining content through new lenses more natural.

    In short: what are more interactive ways of delivering R&D that convey the experience of discovery, and a depth of understanding, better?

    One thing that came up as we tossed this idea over was Ben Eater and Grant Sanderson’s work on explaining quaternions. Try the first video to see what I mean. It may look like a video, but it is, in fact, a choreographed interactive page. There’s a timeline, and narration, and the narrator has their own cursor… but it turns out they are playing with a webpage, and you can play with it too whilst they talk. They even pause to let you have a fiddle. And you can continue to explore when they’re finished. This is a technically complex way of delivering content (and it’s also technically complex content!), but it radically changes the learning process compared to a static video.

    I am not making anything so sophisticated. But I am exploring formats more similar to Hypercard decks or hidden-object Flash games than just a PDF of a slide deck. To that end, I’ve been working with Phaser a fair bit. Ignore the ugly website: Phaser is, effectively, a Flash-like game engine for HTML5, via Canvas and WebGL. For me, it resembles Flixel a lot: an object-y, sprite-y game engine that lets you write ES6.

    I mainly fell on this as the easiest way to play with the idea I had. As it turns out, I could probably do a lot of it in the DOM with modern Javascript, but there’s something about using a tool designed for games, rather than documents, that changes how I work a little, and it made building the prototype I was working on relatively swift. The prototype delivers information, but it also was a way of prototyping content delivery. Already we have something that has pacing, “beats”, and can be replayed or re-explored to meaningful results.

    I am certain we will end up delivering a deck as well. I’m working on one now. But letting people explore an idea, rather than just reading about it, seems like an avenue worth pursuing further.

  • Weeks 386-388

    15 June 2020

    Weeknotes are late. It didn’t seem the right time on Monday 1st June to be prattling about my work practice or the landscape technology on the internet. Make some space for more important messages and voices to be heard.

    At the beginning of week 386, we presented where we were to the team - the output of some discovery work - and we began to formulate a plan for the next steps. And here, I struggled with premise rejection: looking at the brief, reacting to it based on the discovery, and realising every bone in me wants to pivot away from it. The brief is for X; my (not necessarily correct) instinct is to say “…how about (something that is emphatically not-X)?”

    Rather than being the thing I should do, this is a feeling I have to sit with for a bit and own. Sometimes, it’s just down to a bump to my confidence. I am put out by something I have discovered; an unforseen challenge has emerged; whatever has emerged is something I am afraid of. And whatever it is, I just have to work through it.

    At the end of the week, I worked through it a bit on my own, and then shared my thoughts with my colleague. Fortunately, we both agreed on where we were. The discovery phase had, in fact, worked: we had learned a lot, and perhaps needed to pivot a little. What the full details of that pivot were, were unclear, but we agreed that it was needed. And we also both had come to similar conclusions about what we had discovered.

    There was work to be done, but there was no need to panic entirely.

    What then followed over the next few weeks was continuing to work through that. We spoke to a variety of peers through the organisation, shared where we were, and took some of their feedback on for the next chunk. I continued to sketch in paper and code.

    And we chose a direction. Not quite the direction that would take us through to the very end, but a direction to take us along the next part of the journey. We’d take the discovery work and continue to explore and polish with it, just as planned, delivering a first phase that was roughly in line with what we’d promised: see it through, and work up our ideas in more detail. Then, we’d veer off: rather than treating the next two phases as incremental on the first, we’d address two other areas that had emerged in a similar manner. The second phase is feeling relatively clear in terms of topic, if nothing else; the third is perhaps vaguer, but might be shaped over the weeks that preceed it.

    Phase one needs to wrap up next week, so in week 388, I spent a chunk of time making browser-based prototypes, and thinking about how best to make them self-explanatory. Not in the way a good piece of software is, but in the way a good textbook or exhibit is: the code is our example, but it needs content to situate it alongside it. I’m excited to follow this thread, and explore how to present this kind of work.

    And, finally, a nice surprising note. I noticed a small ping from the Slack for Bradnor towards the end of the week, and hurriedly jumped over there to work out what had gone wrong. It turns out: nothing. Rather, a long quiet device gateway had come back online, and the sensors speaking to it had started trickling data into the system automatically and unasked. Exactly how it should have worked, and how it was envisaged. But it’s nice to see something that you had planned to be robust proving its robustness. Happy client, happy me.

  • Weeks 384-385

    24 May 2020

    Whoops, missed a week. I’ve been intensely head-down on the first phase of Easington.

    It always takes me a while to settle into the pace of new projects. I’m eager to start, keen to make headway. It also takes me a while to settle into the pace of new clients: how do they like to work? What are their expectations? What’s the cadence of us meeting, talking, and then me orbiting off to do some work, or sitting down to collaborate.

    And that’s all heightened by doing everything remotely from the get-go. (I’m used to working at a distance, or independently, but still relish collaboration, colocation, and thinking in-person when possible).

    So I spent the past two weeks “cranking the handle”, so to speak.

    But: they’ve been a very rewarding two weeks. I’ve had regular catchups with my Primary Colleague, and have been bouncing up and down the powers of ten that my favourite kind of R&D projects tend to require: from gathering background research, speaking to colleagues, and reading papers through to thinking-out-loud, sketching interactions and ideas, and then, at the far end, pulling one particularly meaty thought together in code as a working, end-to-end prototype.

    That code project took up most of the end of week 384 and all of 385. I proposed that we Just Build A Thing with a particular technology so that we could get a visceral grasp on what it could do. We know what it can do in theory, but it’d be good to feel that for ourselves in a real-world environment. That’ll help us and our stakeholders make strategic decisions about the next steps of the project, as well as help us understand the material we’re working with. It’s also a little gift: something to share back to the team for them to use themselves.

    A lot of that’s come down to the cardboard-and-tape of web technologies, but that’s an exciting space at the weird edges. I’ve poked a bit at Functions As A Service before - AWS Lamba, Cloud Functions - but in this case have been using Cloud Run to apply that idea to a whole Docker container (for $REASONS). A whole container, spun up from cold start, in under a second, to do something on demand, die when it’s done, and we only get billed for compute time. There was still also a chunk of code to write, but a lot of the code for this project is really infrastructure: the lines between things on the block diagram. Once the pipes were set up, we were running an interesting workflow largely on on-demand hosting. None of that is the meat of what’s going on, of course, but it’s still been instructive to put to use, rather just to understand impassively.

    So whilst I was motoring through that, I was also wrapping my head around a new problem domain, one specific problem, a new client, a new project, and a pile of misbehaving code (all written by me, obviously). And so weeknotes slipped, albeit for good reason. Still: good to drop a note at the end of what felt like a good fortnight and say “that felt like a good fortnight”. At the end of it, I had a rewarding, curious, and thought-provoking prototype, ready to demo next week.

    Next week we’ll present where we are and go from there.

  • Week 383

    11 May 2020

    I wrapped up Bradnor this week. I just had a few tweaks left in the code based on client feedback, and a few more to infrastructure - notably, sending deploy notifications from our deploy pipeline through to our error reporting tool.

    With that done, the main job was handover. Part of that was to hand over various services to the client’s control; I always feel better knowing that the appropriate person ‘owns’ control of something, even if we’re at free or low-usage tiers.

    More importantly, it meant documentation. I tidied up the READMEs lying around the place, and then wrote a long document called What We Did which synthesized the various discussions and interim documents into one clear document that could be referred to in future. I find it easiest to write this for an imaginary future developer coming to the project.

    To do that, I assume relatively little specific technical knowledge. So I explain everything we’ve done that either deviates from norms, is domain-specific to the application and product, or that is our ‘configuration’ of existing tools. Beyond that, I link out to documents for open-source tools or products, rather than explaining them myself, but assume familiarity with the core language or framework being used.

    That future developer is, of course, easy to imagine because I think about myself returning to a project after a long gap. It’s also there for the client, who is themselves technical: whilst they’ve been making decisions I’ve put to them, this is a reference document for them, too, so they can see how the things we’ve spoken about join up, and have a final ‘map’ of the infrastructure and code we’ve put together.

    With the final pieces in place, I shipped the documentation, and the client seemed very pleased with it - and the project as a whole. A satisfying end to this phase of work, and perhaps we’ll work together on the project again in the future.

    I got some feedback from the University of Leeds about the courses I wrote for them on Futurelearn. In general, they sounded very pleased: really exciting numbers of sign-ups, and good responses from learners in the comments threads. However, one ‘step’ of a particular course was causing a little confusion. I asked learners to skip over some stages of an external tutorial without quite clarifying why; many of them wanted to do the missing steps, or hadn’t quite worked out how to skip things. They asked me if I could make a short screencast clarifying what to do, and why.

    So I spent a few hours this week back in my screencasting tools, making a short film to explain not just what to do, but why I thought this was a good idea.

    How do I record screencasts at the moment? I record video using the “record area of screen” function built into Quicktime Player, with the audio from my webcam microphone alongside it. At the same time, I am recording my external condenser microphone into Logic Pro, with a small voice channel set up inside the DAW. I usually have a script or notes laid out on a table in front of me. Then, I hit record in Quicktime and in Logic, and just keep going until I have decent takes of everything I need.

    Once that’s done, I fiddle with the voice channel in Logic, to get all the audio up to a nice level, and to remove any background noise. Careful application of the built-in compressor, and occasional Brusfri does the job here. Then, I bounce out the audio to a wav file.

    To edit it, I open all the media up inside Hitfilm, and synchronise the bounced audio from Logic against the ‘guide’ audio from the webcam. Once those are synced, I can remove the webcam audio entirely. Then it’s just a case of walking through the script, chopping and editing, and occasionally deploying small video effects to zoom in on an area, or making small comps to manipulate areas of the screen.

    My goal isn’t to get to something completely final. Leeds have an excellent video team who take this and make it sing, adding B-roll, tidying my edits or comps, and adding titles, stings, and transitions, in line with their branding. Instead, I’m trying to give them enough to work with, to make sure the script and technical video are watertight, and to make the intent of the film clear.

    Once we’d approved my short script, it (as ever) worked out at around an hour’s work per minute of footage - I’m pretty swift at this now, but never seem to be able to break that rule of thumb!

    Finally, I had a quick meeting with the Easington team about that work, and we arranged a kick off meeting for Monday 11th - Week 384.

  • Week 382

    3 May 2020

    Week 382 was primarily a busy week of writing code on Bradnor.

    With last week‘s infrastructure in place, capturing messages from physical devices, we could now spend some time processing that data. That meant abstracting out devices from the locations they represent. After all, a device may go offline, or be replaced by another, but it’d be good to be able to see the history of data from a single location, as well as from a single device.

    So we filled out our data model to encompass concepts such as ‘locations’ and ‘devices’ and the relationship between them (as well as logging when they change) Then, I could build another data-processing task, that would copy a ‘device message’ into a list of messages for a specific location if those two items were linked. (This also made it easy to have a ‘disabled’ flag on devices, making it possible to ignore inaccurate messages from possibly defunct devices). In that copying process, we also do a little decoration and transformation of the data, leading to a nice big table of per-location messages, that’s quick to query.

    I could then backfill our location messages with the data from last week, as well as importing historical data from CSV files straight into the ‘location messages’ table.

    There was also a lot of metadata CRUD to do, to make it easy to update and record information about locations, as well as to leave comments and annotations on many of the objects in our system. Rails made this about as straightforward as it could be to hammer out.

    I made sure I had time to work on some belt-and-braces, too: making sure there was appropriate test coverage (especially of key parts like data processors and the end-to-end request cycle of message JSON arriving at a URL), and setting up Rollbar to catch and collate errors.

    With all that done, we had raw data coming in, meaningful information being derived from that data, and the beginnings of a fleet-management tool.

    Finally, I set up a visualisation pipeline using Grafana. The client had been using Grafana in their previous stack, so it made sense to keep doing so - especially as it was both easy to deploy (thanks to its preference for being deployed as a Docker image) and easy to integrate into Postgres (thanks to the Postgres plugin being supplied as default). With that deployed, we could spelunk away, and a short while hacking away at some SQL got me to a nice dashboard showing data for a set of monitoring locations grouped over time, and navigable with Grafana’s time-series tools (which make it easy to scroll around time and to zoom in and out). As new monitoring locations were added and new historical data dropped in, more lines appeared in the graph. Satisfying to see!

    All this meant I largely wrapped up Bradnor this week. There’s just some spit and polish and handover reamining.

    It’s not the most sophisticated set of tools, but it is built out of well-known building blocks - application frameworks, databases, protocosls - that are maintainable, testable, and knowable. We’ve simplified the platform infrastrcture a little, but still have a good base to build upon, perhaps to add new features to or to extract to smaller services if necessary. Tests help verify that the code is doing what it should be, and by using known, mature tools, it becomes easier to recruit others to work on it should I be unavailable. I was pleased with the shape of this project - what looked like a quick software build project actually turned in an opportunity to lay some good foundations, re-examine infrastructure, invest in more than just lines of code.

    On other fronts, I signed paperwork for Easington, which should kick off in week 383, and take me right through the summer. This is going to be an exciting, challenging R&D project to pour myself into, and I’m looking forward to it.

  • Week 380

    17 April 2020

    Where were we?

    I last wrote notes around Week 374. My Makefile tells me this is about Week 380. I think that’s correct. If not, well, time has slightly lost some of its meaning in recent weeks, and who’s counting? Week 380 it is.

    In week 375, I finally finished my career review, and [wrote that up]. That was a prelude to more formally seeking out new projects and clients. Of course, what then happened was COVID-19 made it quite clear that we were not proceeding as normal for a bit. I left the studio and went to work from home, and started trying to investigate new work from there.

    Which was not, at that point, particularly fast-moving, and, coupled with the strangeness of lockdown, everything slowed down a little. It was going to be a challenge to write ongoing weeknotes where I invented euphemisms for “not very busy over here”, so I went a little quiet.

    When I write down what I’ve been up to since then, though, it’s a decent amount:

    • I made voipcards. This was, initially, one of my one-line-gags turned into a small project. It was also a useful tool to prod at learning a bit more Svelte, to practice building PWAs, and to occupy my mind. It turned out quite popular on the internet, which led to me writing about the problems of solutionising, and why I’m still not sure it’s that good a project.
    • I released the 2.0.x firmware for 16n, and wrote about that here. This had been on the shelf for a different project - Mayhill - for a while, and I realised it could easily be ported to 16n. The big feature this introduces is configuring your hardware from the browser, over USBMidi. Really pleased with how this turned out, and the community feedback has been great.
    • I built up a personal electronics project over a few days, which turned out rather well after some fettling. Fun things I learned here included using naked board substrate as a transparent surface for LEDs to shine through, how to drive 256 LEDs off only 64 channels (four sixteen-LED drivers chained over I2C), and then tweaking the update rate of the LEDs so they don’t flicker on cameras as well as to the naked eye. (That involved moving the update rate to an integer division of 30 frames a second…)
    • been spending some time volunteering on Makerveristy’s PPE effort - primarily, on a tangential project to the 3D printing they’ve been launching, where I’ve been lending some support on digital logistics work as well as comms and lightweight project management.
    • pitching a bit and having phone-calls and chats.
    • quite a lot of business-related admin.
    • setting up two new projects. Let’s called them Bradnor and Easington. I signed the contracts for Bradnor, a short project around infrastructure for an IOT project, last week, and we’re nearly there with Easington.

    That felt like enough to finally write about. And now I’m back in the saddle, it should be harder to break the chain next week. As ever: onwards.
