Housing Tech and Tilted Platforms

I have a new article out now in a special issue on platform urbanism, co-authored with Max Besbris, David Wachsmuth, and Jake Wegmann, titled Tilted Platforms: Rental Housing Technology and the Rise of Urban Big Data Oligopolies. We reflect on short-term and long-term rental housing technologies and how they’re affecting the housing search, equity, and affordability.

From the abstract:

This article interprets emerging scholarship on rental housing platforms—particularly the most well-known and used short- and long-term rental housing platforms—and considers how the technological processes connecting both short-term and long-term rentals to the platform economy are transforming cities. It discusses potential policy approaches to more equitably distribute benefits and mitigate harms. We argue that information technology is not value-neutral. While rental housing platforms may empower data analysts and certain market participants, the same cannot be said for all users or society at large. First, user-generated online data frequently reproduce the systematic biases found in traditional sources of housing information. Evidence is growing that the information broadcasting potential of rental housing platforms may increase rather than mitigate sociospatial inequality. Second, technology platforms curate and shape information according to their creators’ own financial and political interests. The question of which data—and people—are hidden or marginalized on these platforms is just as important as the question of which data are available. Finally, important differences in benefits and drawbacks exist between short-term and long-term rental housing platforms, but are underexplored in the literature: this article unpacks these differences and proposes policy recommendations.

Urban Form and OpenStreetMap

My chapter “Exploring Urban Form Through OpenStreetMap Data: A Visual Introduction” has just been published in the new book Urban Experience and Design: Contemporary Perspectives on Improving the Public Realm edited by Justin Hollander and Ann Sussman.

From the abstract:

This chapter introduces OpenStreetMap—a crowdsourced, worldwide mapping project and geospatial data repository—to illustrate its usefulness in quickly and easily analyzing and visualizing planning and design outcomes in the built environment. It demonstrates the OSMnx toolkit for automatically downloading, modeling and visualizing spatial data from OpenStreetMap. We explore patterns and configurations in street networks and buildings around the world computationally through visualization methods—including figure-ground diagrams and polar histograms—that help compress urban complexity into comprehensible artifacts that reflect the human experience of the built environment. Ubiquitous urban data and computation can open up new urban form analyses from both quantitative and qualitative perspectives.

Outlook to Google Calendar Sync

Ah, the travails of academia. Like many universities, USC uses Microsoft Outlook as its email and calendar provider. This presents some integration challenges for those of us, like me, who use Google Calendar everywhere else in life. It’s effectively impossible to sync an Outlook Calendar with a Google Calendar, so I had to juggle between both when trying to schedule anything. Chaos ensues.

So, I created a script to perform an ongoing one-way sync from my USC Microsoft Office 365 Outlook calendar to my personal Google calendar, handling new, updated, and deleted events. I had to develop my own solution because Microsoft/Google inexplicably can’t get their own acts together. For example, you can publish your Outlook calendar’s ICS URL and add it to Google, but it only syncs roughly once per day so you miss any new appointments in the meantime. Microsoft Flow used to work (clumsily) for syncing, but even their official recipes are now broken. So I had to roll my own.

AnyConnect VPN on Linux

I run Linux on my school computer, which I brought home to get work done during the stay-at-home order. But when I tried to set up a VPN connection, I was surprised to discover that USC IT didn’t seem to provide a Linux client for Cisco AnyConnect. When I contacted them to ask how to connect, I was informed that “at this time IT doesn’t support Linux.” Shrug emoji.

Fortunately I do support Linux, so if anyone else wants to connect to the USC AnyConnect VPN, here’s how. You could roll your own solution using OpenConnect and a vpnc-script, but that’s complicated. Instead, you can download a current Linux client for Cisco AnyConnect here (you’re welcome). Install it and run it.

You want to connect to sslvpn.usc.edu (the normal vpn.usc.edu server does not work here). To log in, enter your normal USC username and password. For “second password” open your Duo Security app, generate a two-factor code, and enter it here. And ta-da, you’re in.

Online Rental Housing Market Representation

My article, Online Rental Housing Market Representation and the Digital Reproduction of Urban Inequality, has just been published in Environment and Planning A (download free PDF). It explores the representation of different communities in online rental listings from two perspectives: 1) how might biases in representativeness impact housing planners’ knowledge of rental markets, and 2) how might information inequality impact residential mobility, community legibility, gentrification, and housing voucher utilization?
