whoa this looks fascinating, i've never heard of it before! thank you for the link :)

To add to lproven's point.

An article called "A Spreadsheet and a Debugger walk into a Shell" [0] by Bjorn (letoram) is a good showcase of an alternative to cells in a Jupyter notebook (Excel like cells!). Another alternative a bit more similar to Jupyter that also runs on Arcan is Pipeworld.

Probably closer to the first situation. It curb stomped ArcGIS in the geographic information system community. When I started working with GIS at work, expensive ESRI products were default in this market, a la matlab in another field. Most coleages of mine had not heard about QGIS. Now QGIS is ubiquitous. It did to ArcGIS and its countless paid add on modules what scipy/numpy did to matlab.

The scipy/numpy to matlab is a good example. In my opinion it is on its way but in many places the timing is more like 2010-2013 where a lot of people knew python was the future but universities still used only Matlab.

Is this on its way to pushing out the incumbent proprietary solution and becoming the standard a la Blender? Or is this more LibreOffice -it’s there, but missing so much functionality/polish that an expert will immediately find blockers vs the status quo?

ingenieroariel · 3 months ago

I think the answer depends on the country: In places where the government uses QGIS it is like Blender. In places where ESRI has a stronghold it is like LibreOffice.

Mark Knol is a great generative coding artist: https://github.com/markknol/

Chris Randall is pretty awesome too: https://www.instagram.com/chris.randall.art/

If you care about that and have a data source, you can add, for example, population density per H3 cell as part of your analysis. That has the additional benefit of denoting the this quantity of interest explicitly, rather than some implicitly assumed correlation which may not be true.

ingenieroariel · a year ago

Hey AJ, this is almost on topic, do you know of a more up to date version of the dataset you used on the blog post release for H3 v4.0.0 [1]? They stopped updating in Oct 2023. Thanks! [1] https://data.humdata.org/dataset/kontur-population-dataset

from the about

"Arcan is a powerful development framework for creating virtually anything between user interfaces for specialised embedded applications all the way to full-blown standalone desktop environments. Boot splash screen? no problem. Custom Interface for your Home Automation Project? sure thing. Stream media processing? Of course."

Still dont really understand what this is?

ingenieroariel · a year ago

It is a gui framework that allows you create terminals where you can detach any running process into another terminal.

Since it is a complete toolkit, you can have detachable applications where you send both code and state to a server and retrieve it from another device (like Apple's continuity).

In the end it is just a bunch of lua scripts talking to other components via /dev/shm and to other computers using a new protocol called a12://

Not saying Nix(os) Is The Way, but sometimes it does ok.

I did not believe you and just typed it on OSX, half a minute later the app was ready for me to use.

in my [albeit outdated] experience ArrowJS is quite a bit slower than using native JS types. i feel like crossing the WASM<>JS boundary is very expensive, especially for anything other than numbers/typed arrays.

what are people's experiences with this?

ingenieroariel · 2 years ago

I'll let Kyle chime in but I tested it a few months ago with millions of polygons on an M2 16GB of RAM laptop and it worked very well.

There is a library by the same author called lonboard that provides the JS bits inside JupyterLab. https://github.com/developmentseed/lonboard

<speculation>I think it is based on the Kepler.gl / Deck.gl data loaders that go straight to GPU from network.</speculation>

> and may surprise you at any point in time with ever higher bills without higher usage.

What? really? Do they change your pricing plan? How can they charge more for the same usage?

ingenieroariel · 2 years ago

When you queried their 'Open Data' datasets and linked with your own it was absurdly cheap for some time. Granted we used our hacking skills to make sure the really big queries ran in the free tier and only smaller datasets got in the private tables.

I kept getting emails about small changes and the bills got bigger all over the place including BigQuery and how they dealt with queries on public datasets. Bill got higher.

There is a non zero chance I conflated things. But from my point of view: I created a system and let it running for years - afterwards bills got higher out of the blue and I moved out.
