Quick Summary

A new search tool called Sightline is bringing the discovery methodology of Shodan to the physical world. While Shodan famously indexes exposed internet services, Sightline applies similar principles to real-world infrastructure using OpenStreetMap data.

The tool enables users to search for physical assets like telecom towers, power plants, and data centers across global locations. It represents a novel approach to infrastructure discovery that could benefit researchers, analysts, and curious explorers alike.

The Concept Behind Sightline

The core idea behind Sightline is straightforward: apply internet-style search to physical infrastructure. Just as Shodan makes it easy to explore exposed internet services, Sightline aims to make physical infrastructure discoverable through search.

Users can query for specific infrastructure types using natural language searches like "telecom towers in karnataka" or "power plants near mumbai." The system also supports more precise structured queries for advanced users.

The tool's approach represents a significant shift in how we think about infrastructure discovery. Rather than relying on manual research or specialized databases, it leverages the comprehensive OpenStreetMap dataset.

Shodan makes it easy to explore exposed internet services. Sightline applies the same idea to the real world.

"Shodan makes it easy to explore exposed internet services. Sightline applies the same idea to the real world."

— Sightline Project Description

Technical Architecture

Under the hood, Sightline relies on a robust technical stack designed for geographic data processing. The system uses the Overpass API for querying OpenStreetMap features, providing access to a vast repository of geographic data.

For location resolution, the tool employs Nominatim, which handles the complex task of resolving countries, regions, and cities from search queries. This combination allows for precise geographic filtering without requiring users to know exact coordinates.

Notably, the system avoids hardcoded geography, making it flexible enough to handle queries from anywhere in the world. The parsing mechanism is deterministic and rule-based, operating without AI inference to ensure consistent, predictable results.

  • Overpass API for OSM feature queries
  • Nominatim for geocoding and location resolution
  • Rule-based parsing without AI inference
  • No hardcoded geographic boundaries

Search Capabilities

Sightline offers two primary search modes that cater to different user needs. The natural language interface allows for intuitive queries like "data centers in paris france," making the tool accessible to non-technical users.

For more precise searches, the system supports structured queries with specific parameters. Examples include type:telecom operator:airtel region:karnataka or type:data_center operator:google, enabling targeted infrastructure discovery.

The tool's flexibility allows users to explore infrastructure across different scales—from local searches to global queries. This versatility makes it valuable for various use cases, from academic research to commercial planning.

Key search capabilities include:

  • Infrastructure type filtering (telecom, power, data centers)
  • Operator-specific searches
  • Regional and geographic constraints
  • Combined parameter queries

Availability and Access

Sightline is available as an open-source project, with the source code hosted on GitHub. This transparency allows users to examine the implementation, contribute improvements, or deploy their own instances.

A live demonstration is accessible through a web interface, providing immediate access to the search functionality. The tool's design prioritizes ease of use while maintaining powerful query capabilities.

The project represents a practical application of open data principles, combining publicly available OpenStreetMap information with specialized search functionality. Its open-source nature encourages community development and adaptation for various use cases.

Looking Ahead

Sightline demonstrates how existing internet search paradigms can be adapted to physical-world discovery challenges. By leveraging comprehensive geographic datasets, it creates new possibilities for infrastructure analysis and exploration.

The tool's approach—combining natural language search with structured queries—makes complex geographic data accessible to a broader audience. As open data initiatives continue to expand, tools like Sightline may become increasingly valuable for researchers, analysts, and curious individuals seeking to understand our physical infrastructure landscape.

US wins against Russian and Chinese air defenses in other countries risk teaching the wrong lessons

Stealth fighters and supersonic bombers were among the aircraft involved in the mission. US Air Force Photo The US assault on Venezuela saw forces overwhelm Russian- and Chinese-made air defenses. Operator and maintenance issues appear to have played roles in air defense failures. The operation offers some insights into the effectiveness of US tactics, but there are potential risks in reading too much into the wins. US forces that executed a raid in Venezuela to capture its now-former leader walked away with no aircraft lost to the country's Russian-made air-defense systems and Chinese-made radars. In the aftermath, US Secretary of Defense Pete Hegseth said that it "seems those Russian air defenses didn't quite work so well, did they?" He didn't elaborate any further, but in briefings, the top US general spoke about how US forces dismantled and destroyed enemy air defenses. While the US can draw a certain degree of confidence in its capabilities from the success of the mission, there's a risk of reading too much into that success, especially when it comes to weapons made by American rivals in the hands of other militaries. Some of the failures of the Venezuelan-operated foreign air defenses, for example, have been attributed to issues like inactivity, incompetence, and a dearth of functional cohesion between different systems. Wins in Venezuela during Operation Absolute Resolve or in operations against Iranian-operated Russian-made air defenses may not translate the same in fight with Russia or China. Venezuelan air defense failures Seven US troops were hurt during the raid in Venezuela over the weekend, a defense official said. US Air Force photo by Airman 1st Class Isabel Tanner The US operation in Venezuela to capture former president Nicolás Maduro and his wife earlier this month was a large, complex undertaking involving over 150 aircraft, including a mix of F-35 and F-22 stealth fighters, F/A-18 jets, EA-18 electronic attack jets, E-2 airborne early warning planes, bombers, and other aircraft, including drones. As the apprehension forces approached the fortified target facility at Fuerte Tiuna, a military installation in the capital Caracas, US aircraft began striking Venezuelan air defenses to open a corridor for helicopters flying at low altitudes along a preset path. Planners expected significant resistance, but the air defense network capitulated under overwhelming US pressure. The US used a mix of tools to knock out the air defenses, including AGM-88 anti-radiation missiles that home in on radar systems and electronic jamming. Victory may not have come solely from American combat power though. "The Venezuelan crews were apparently unprepared as they located many air defense positions in the middle of fields rather than under camouflage," Mark Cancian, a retired Marine Corps colonel and defense expert with the Center for Strategic and International Studies, told Business Insider. Those systems were vulnerable to US forces. There were other problems, as well. After Operation Absolute Resolve, some reports suggested Venezuela didn't have some systems connected to radars when US air power arrived for the operation. "That's stunning fecklessness," Michael Sobolik, a senior fellow at the Hudson Institute, said. Long-standing issues within Venezuela's air defense network, particularly regarding maintenance and sustainment of its Russian air defenses and Chinese radars, has been noted by experts and analysts, revealing serious shortcomings with regard to the condition of its defense technologies. Cautious insights A destroyed air defense unit at a Venezuelan military base. Leonardo Fernandez Viloria/REUTERS So what exactly can Western militaries discern from the performance of Russian and Chinese systems in Venezuela? It is difficult to say with certainty, at least with the information presently available in the public discourse. Before the US assault operation, the Venezuelan military was assessed to have Russian S-300VM batteries, Buk-M2 systems, S-125 Pechora-2M launchers, and Chinese YJ-27 radars. Last November, a Russian lawmaker said that Moscow had delivered new Pantsir-S1 and Buk-M2E systems to Venezuela. It's unclear which systems were operational at the time of the US raid. Venezuela also possessed Chinese-made YJ-27 radars, which are used to detect and determine engagement procedures for hostile air targets. Beijing has touted these systems as state-of-the-art, asserting that they can detect stealth assets like the F-22 and F-35 from over 150 miles away and are resistant to jamming. Sobolik told Business Insider that what matters more than these claims is how systems perform in a real conflict. The radars, like the Russian-made defenses, appear to have been of little use. The US and its partners have thwarted Russian-made air defense systems in other conflicts as well. Israeli airpower, for instance, defeated Russian air defenses in Iran. The US did the same when it launched Operation Midnight Hammer and struck Iranian nuclear facilities. Like the Venezuela mission, these were extensively planned operations involving significant force against weaker export variants operated by potentially insufficiently trained operators. Russian air defenses have been more effective in Ukraine, though there have still been combat losses, even for advanced systems like the S-400. "The emerging picture is that these systems can handle low and medium threats but not the most challenging attacks represented by the United States and Israel," Cancian said. That said, US and allied airpower have not been tested against the full capabilities of Russian and Chinese integrated air defense networks. The US advantage China's JY-27A radar didn't appear to be effective during the US raid on Venezuela. US Air Force Photo Facing these considerations, Houston Cantwell, a retired US Air Force brigadier general and expert at the Mitchell Institute for Aerospace Studies, told Business Insider that maintaining the technological advantage and preserving combat readiness are essential to securing the upper hand. A key example, he said, is the F-35 Lightning II Joint Strike Fighter, which "has proven time and time again that it gives its warfighters an advantage in the air" and "lowers the risk to the warfighter while providing more options to the political decision makers." Continued proficiency in maintaining and operating advanced aircraft like the F-35 is expected to give the US an airpower advantage over adversary air defenses. To what extent the Venezuela mission reflects that edge, though, is unclear. Read the original article on Business Insider

When my kids went to college, I missed our family dinner nights. Virtual get-togethers give me the connection I crave.

When my kids went to college, I missed our family dinner nights. Virtual get-togethers give me the connection I crave.

The author missed family dinners when her sons were in college. Courtesy of Cristine Struble When my sons were growing up, we would have Sunday night family dinners. Now that they're in college, I send pizzas to their dorms, and we all eat together via FaceTime. Although nothing will replace being in person together, this time let's all connect as a family. In my family, Sunday was always family dinner night. Whether the Packers earned another triumphant win, a swim meet went late, or a last-minute homework assignment loomed on Monday morning, that time to eat and enjoy each other's company was an appointment that could not be canceled. When my two boys headed off to college, Sundays became more subdued. Yes, my husband and I opened a bottle of wine and enjoyed our dinner leisurely, but I craved more. The meal needed something; it needed that seasoning from my sons' snarky retort, a roaring laugh, and even that persistent eye roll. Luckily, I created a solution. I order pizza with a side of family togetherness Since I missed our weekly family dinners, I started a monthly family pizza night across the miles. The idea is simple: I pick a day and time, compile the orders, and everyone gets a pizza delivery at the same time. Whether it is my oldest, who wants copious amounts of meat on that slice, or the younger one, who prefers variety, I order enough for everyone — including all the roommates and friends. Then we jump on video calls and chat while we eat. The phrase "everyone is family at the table" is cliché, but everyone is welcome to join. No, I do not force friends to chat, but they must appreciate my "rules." It is not rapid-fire Socratic questioning, but people cannot just devour food and disappear. Everyone sends pizza photos, curious comments, and FaceTimes while we are eating. Yes, it sounds like the dinner parties people hosted in 2020, but it works. We catch up, laugh, and just have a collective moment. Sure, I cannot cajole the boys as easily through a screen, but I can get a response that is more than just a one-word text reply. It's the only way to connect with my kids while they're in college Of course, some people will say I'm bribing my kids to interact with me, but it doesn't matter to me. The reality is that family traditions are not just holidays, birthdays, or other special occasions. Making time for each other is vital, and food can be the catalyst. The author's son and his friend eat pizza together. Courtesy of Cristine Struble At, around, and by the table, I have learned much about my sons over the years. It was more than excitement over a good grade or disappointment about a lost swim race. I have seen their better understanding of personal relationships, their appreciation for culture, and their interest in family history. Listening to their word choices and argument construction, and even just watching them sit quietly, is far more telling than another call or text when they are away from home. I might have nurtured them with food, but they grew into the men that they are today because of our family connection. This current pizza dinner might be a slice of what we had, but it is one that I crave even more. I hope we'll have pizza night for years to come While my pizza night family dinner solution works with college kids, I look forward to keeping this tradition going long after they graduate. Whether one is in Florida and the other is halfway around the world, we can and should make our family a priority. Every overlooked opportunity is a missed one. Since pizza, or some version of flatbread, can be found anywhere in the world, there are no excuses for skipping this dinner. Even on a cruise ship in the middle of the ocean, family pizza night is on the schedule. No matter how I slice it, the concept works. For any parent looking to keep family bonds strong, creative solutions are all around. Whether it is a pizza, grandma's cookies, or a Big Mac, food is a form of communication. My family tradition tells my boys that the time we spend together nourishes me far beyond the food served on the plate. Read the original article on Business Insider
