Devon - if I had any GB£ I'd convert them to diamonds to sew into my turn-ups. But my day-to-day income is nicely hedged, with a small but significant part coming in as US$. So if Sterling crashes along with Old Blighty, I'll still be able to afford an M16. If not a new Mac.
On the Jupyter front, a lot of water has gone under my bridge, which is why it's all gone all quiet with me. I took a deep breath and downloaded Anaconda 3… https://www.anaconda.com/what-is-anaconda/ and my whole view of the world changed. Suffice to say I'm a convert – at least to Jupyter, if not to Anaconda (just yet). As well as Jupyter Notebook (which is the only on-topic app as far as this thread is concerned) there are a lot of cool toys to play with. But I must eat my words about Martin Saurer's J "kernel" for Jupyter needing to be one notch down in macOS level (from OS X 10.12 to 10.11) and 2 notches up in J level (from j805 to j807)… Anaconda 3 has done away with the first notch. It takes a relaxed view that its seething masses can't be assumed to be all on the latest macOS, and so it only demands OS X 10.10 or above. So… at this point I have a fancy dashboard with a button marked Jupyter Notebook (and another one marked JupyterLab, which is another tale entirely). The trailing edge has never looked so good. I can now download a Jupyter "notebook" from anywhere (extension .ipynb) and open it to read it. Though I can't launch it by doubleclicking it – AFAICT I must go through the Jupyter dashboard to find it on my disk and open it. If it contains J code I can read the code. But without a J "kernel" I can't re-execute it. (Of course). Alas… Anaconda 3/Jupyter comes with Python 3 as the only kernel pre-installed. WIBNI (wouldn't-it-be-nice-if) it came with both Python 3 AND j807. But it doesn't. Not yet. And until it does, a Jupyter notebook (.ipynb) is not on a level with a J lab (.ijt), because J labs work straight out of the box. But to make a Jupyter notebook work with J, specifically j807, there's "some soldering required". But here's where Martin Saurer's jkernel package comes into its own… https://github.com/martin-saurer/jkernel I was able to follow Martin's instructions – blindly and to the letter – and hey presto: any notebook written for J can now make use of the "jkernel" engine. Just choose Menu: Kernel > Choose kernel… > J and you see a big red J in the top right of the Jupyter window instead of the Mayan snake. Having achieved that, I fancy my chances on being able to upgrade the J kernel to j807. Haven't done so yet because other things have supervened. But I'll try writing a notebook to support the task (…yes really), just to get to grips with my new tool. One little wrinkle would make the Brave New World even braver – how can I get J to tell it's being run as a Jupyter kernel? For a start, I'd like to conditionally suppress all smoutputs in my startup script. All I've discovered as yet is (0 -: #ARGV) . In time, WIBNI we had IFJUPYTER, like IFQT etc. On Fri, 1 Feb 2019 at 03:40, Devon McCormick <devon...@gmail.com> wrote: > Ian - I hope you've converted all your £s to something solid like gold or > bitcoin before the falling off the cliff thing happens. > I'm still clutching onto my Windows 7 - along with my guns and religion - > until I'm forced to move to one of the dark sides like Linux or Mac - for > as long as I continue to be in the fat part of the curve for upgrades if > not new releases.
