📢 New preprint: Urban highways are barriers to social ties: arxiv.org/abs/2404.11596

We overlay the highway network with a massive, geolocated online social network (Twitter 2012), and measure how social ties are impacted by highway segments. We find a strong barrier effect in all 50 considered US cities. See below - the red squares show that this effect is stronger for short distances.

@TheWarOnCars #geospatial #urbanism #segregation #datascience

Map showing a highway section in red and social ties in space crossing the highway. Wherever a tie crosses the highway, there is a cross. There are 94 crosses.
Figure of a heatmap (left) and a bar plot(right) over 50 cities. (Left) Heatmap of all Barrier Scores B(d) grouped into 0.5 km bins of social tie distance. Color denotes Barrier Score, square size denotes the fraction of social ties in each distance band relative to all ties in the city. All cities have positive Barrier Scores over most distances. Often, there is a smoothly reached peak distance, for example in Orlando at around dpeak ≈ 1.5 km. The top row labelled “ALL CITIES” reports the distance-binned Barrier Scores averaged over all cities. (Right) The bar plot labelled “CITY” reports the Barrier Score B calculated considering all ties with distances up to 10 km.

Francesco P Lovergine :debian:

A due #introduction to myself. I'm an old-style #geek with more than 30 years of experience with multiple flavors of *nix, networking, #FOSS, and development. I'm a researcher and data scientist in the #geospatial and #remotesensing domains, with a background in #computervision and #HPC. I'm also a #Debian Developer, a full-stack dev, and a system administrator, because of my geekness. I'm a type of CS professional that is currently almost extinct, I would say...

Axman6 | 🇦🇺

Been here for several months now, so I guess it’s time update my #introduction post! The following is probably inaccurate!

I’m Alex, better know as Axman6 pretty much everywhere you can think of - IRC (libera.chat#haskell etc.), 🦤 site, probably LinkedIn and others too.

As far as jobs and hobbies are concerned, I’ve been a professional #Haskell developer for nearly a decade, with various roles in finance and #HFT (despite not really having much of an interest in finance…), in the public sector where I worked on much of the #RenewableEnergy parts of nationalmap.gov.au at #NICTA & #CSIRO, writing backend services in Haskell, doing lots of #geospatial data processing, #SQL, #DevOps and much more.

Previously writing #Daml, a dialect of Haskell, for a large financial system. Currently working for a Canberra based startup making scientific test and measurement equipment using #FPGAs, #python & #C.

if you’re in need of an experienced remote Haskell dev who loves to make things go fast, I’d love to have a chat.

Previously undertaking Masters in #cybersecurity at #UNSW but gave it up because of the lack of advanced content.

I’ve got a strong interest in #cryptography, #integrity, as well as #hacking things to see how they work, and love a good #CTF.

On the more personal side of things, I’m based in #Canberra, #australia. As you can see from my profile pic, I’m also a volunteer in the State Emergency Service - I guess you could say I like pin coladas, and talking walks in the rain… in a storm… on your roof… with a chainsaw⛈️

Davie Dean

Updating my #introduction again. I'm loving the #queer and particularly the #trans community here, so I'm changing this account to Davie Dean to better show that side of me. I'm proudly #trans, #nonbinary and #bigender. On here my pronouns are she/her, but I also enjoy being David and he/him most of the time elsewhere. :transgender_flag: :enby: :flag_bigender:

In non #gender stuff, I'm a #geospatial data enthusiast with a passion for #OpenStreetMap and #indigenous mapping. Love #renovating my caravan and house on the side. I'm getting deeper into #geospatial #datascience and #datavisualization. Proudly based on #Ainawan land in #Armidale, NSW.

Updated - needs a photo!

I think I need some #geospatial help.

I have a #GeoJSON file which is ~10MB. Even when compressed it is about 2MB.

It provides a cluster of ~28k points displayed on a #Leaflet map.

Is there a sensible way to make this more efficient? Can I start will a small GeoJSON of just the clusters and then "stream" in more detailed files when users zoom in?

Just published a Behind-The-Scenes blog post about my AIS Shipping Animation from #30DayMapChallenge

Read about the project from concept to final animation - setting up a PI4 to obtain AIS data, importing to Blender, geometry nodes, it's all there....

Only now that I have finally written this up, am starting to understand why this 30 second animation was almost a year in the making
