    1. Recognising that it is expensive to maintain a pool of IP addresses in every potential user location, these companies have also proposed a new HTTP header to allow clients/browsers to directly convey geolocation information through any privacy relays that may be present.

      There's a new HTTP geo header! I had no idea!

    1. Mr. Trump will doubtless claim that only he was willing to use America’s military reach to achieve a goal his last four predecessors deemed too risky.

      His predecessors didn't have the same geo-political benefits in play that he did, specifically the Israel situation mentioned earlier in the article:

      After Israel’s fierce retaliation for the Oct. 7, 2023 terror attacks that killed over a thousand Israeli civilians, Iran is suddenly bereft of its proxies, Hamas and Hezbollah. Its closest ally, Syria’s Bashar al-Assad, had to flee the country. And Russia and China, which formed a partnership of convenience with Iran, were nowhere to be seen after Israel attacked the country.

      Wi-Fi Positioning Systems are used by modern mobile operating systems to geolocate themselves without the use of GPS. Both Google and Apple, for instance, run Wi-Fi Positioning Systems for Android and iOS devices to obtain their own location using nearby Wi-Fi access points as landmarks.

      In this work, we show that Apple's Wi-Fi Positioning System represents a global threat to the privacy of hundreds of millions of people. When iOS devices need to geolocate themselves using nearby Wi-Fi landmarks, they transmit a list of hardware identifiers to Apple and receive the geolocations of those access points in return. Unfortunately, this process can be replicated by an unprivileged adversary, who can recreate a copy of Apple's Wi-Fi geolocation database by requesting the locations of access points around the world with no prior knowledge.

      To make matters worse, we demonstrate that by repeatedly querying Apple's Wi-Fi Positioning System for the same identifiers, we can detect Wi-Fi router movement over time. In our data, we see evidence of home relocations, family vacations, and the aftermath of natural disasters like the 2023 Maui wildfires. More disturbingly, we also observe troop and refugee movements into and out of the Ukraine war and the impact of the war in Gaza.

      We conclude by detailing our efforts at responsible disclosure, and offer a number of suggestions for limiting Wi-Fi Positioning Systems' effects on user privacy in the future.

    1. We have always done geo-engineering, from the prairies of Native Americans to European forests, from Indian to Chinese rice fields. Now that we can no longer deny our impact and the responsibility it entails, it’s time to open our eyes and consciously do geo-engineering.

      This is odd. 'we have alway done geo-engineering in the sense that we had large scale negative impacts on the globe' unintentionally, so let's do it more and with more focused intention. The leap here is not in geo-engineering David, the leap is in thinking you are capable of seeing it through without externalisation. With a guy that says you can engineer yourself out of complex issues....

    1. Abstract GeoDCAT-AP is an extension of the DCAT application profile for data portals in Europe (DCAT-AP) for describing geospatial datasets, dataset series, and services. Its basic use case is to make spatial datasets, dataset series, and services searchable on general data portals, thereby making geospatial information better findable across borders and sectors. For this purpose, GeoDCAT-AP provides an RDF vocabulary and the corresponding RDF syntax binding for the union of metadata elements of the core profile of ISO 19115:2003 and those defined in the framework of the INSPIRE Directive of the European Union.
