Digital Flapjack

Pondering test data selection Last week I talked about two strands of work on the habitat map work: improving the robustness of my validation approach, and integrating eBird into my occurrence data alongside that from GBIF.

Habitat maps Missing data As mentioned last week, I'm working towards doing a regional habitat map based on global data, to see if we can utilise Tessera's global reach to make up for local data-deficiencies.

Habitat maps My plan was to do a semi-global run this week, but to get there I ended up with a stack of small steps towards that which instead took up the time.

Last two weeks Copenhagen I missed my weeknotes last week due to being away in Copenhagen for a few days.

Last week Liverpool Makefest 2026 Liverpool Makefest 2026 happened on Sunday and seemed to go well.

Last week Local developments This week I attempted to make a more nuanced version of my habitat map than I have done to date, and I'm glad I did, as it turned up some hidden problems with my data-processing that were obscured in the previous simpler versi…

Last week Habitat mapping After a few weeks of incremental improvement, I finally hit a stage where "progress" lead to regression in the results of my attempt to build up a habitat map.

Last week Tessera group meeting On Monday there was a small Tessera group show-and-tell in the lab for one of the funders, where I presented some of the habitat map work I've been doing with Tessera.

Last week Both tardy and sparse weeknotes.

Last Week Tessera Habitat Mapping I'm continuing to push forward mostly on the habitat mapping work, with occasional side quests into tooling bits I need to support that (changes to Yirgacheffe and Geotessera, more on that below).

Last Week Words not come good today - I basically blew all my writing energy on another post that is not yet published (explained below), and so this one will be quite short (other than the later sections, which I wrote as I went along last week).

Last Week Habitat mapping with Tessera Last week I spent most the week down in Cambridge, primarily for a group meeting that David Coomes' group were having to review what Tessera related habitat mapping projects they have going.

Last week Weeknotes After six months of trying to write as-I-go-per-topic weeknotes, rather than one-a-week-all-topics weeknotes, I declare the experiment a failure, and I'm going to switch back to per-week.

Last week we took our semi-regular trip to the Uffington White Horse, a 3000 year old horse carved into the chalk of a hillside somewhere between Swindon and Oxford.

I wrote a few weeks ago about wanting to move the OCaml based software I wrote to host this and my other websites, called Webbplats, over to OCaml's new Effect based I/O system (EIO).
