The World’s First Podcaster?

When do you think the first podcast occurred? Did you guess in the 1890s? That’s not a typo. Telefonhírmondó was possibly the world’s first true “telephone newspaper.” People in Budapest could dial a phone number and listen to what we would think of now as radio content. Surprisingly, the service lasted until 1944, although after 1925, it was rebroadcasting a radio station’s programming.

The whole thing was the brainchild of Tivadar Puskás, an engineer who had worked with Thomas Edison. At first, the service had about 60 subscribers, but Puskás envisioned the service one day spanning the globe. Of course, he wasn’t wrong. There was a market for worldwide audio programs, but they were not going to travel over phone lines to the customer.

The Hungarian government kept tight control over newspapers in those days. However, as we see in modern times, new media often slips through the cracks. After two weeks of proving the concept out, Puskás asked for formal approval and for a 50-year exclusive franchise for the city of Budapest. They would eventually approve the former, but not the latter.

Unfortunately, a month into the new venture, Puskás died. His brother Albert took over and continued talks with the government. The phone company wanted a piece of the action, as did the government. Before anything was settled, Albert sold the company to István Popper. He finalized the deal, which included rules requiring signed copies of the news reports to be sent to the police three times a day. The affair must have been lucrative. The company would eventually construct its own telephone network independent of the normal phone system. By 1907, they boasted 15,000 subscribers, including notable politicians and businesses, including hotels. Continue reading “The World’s First Podcaster?”

Ore Formation: Introduction And Magmatic Processes

Hackaday has a long-running series on Mining and Refining, that tracks elements of interest on the human-made road from rocks to riches. What author Dan Maloney doesn’t address in that series is the natural history that comes before the mine. You can’t just plunk down a copper mine or start squeezing oil from any old stone, after all: first, you need ore. Ore has to come from somewhere. In this series, we’re going to get down and dirty into the geology of ore-forming processes to find out from wither come the rocks that hold our elements of interest.

What’s In an Ore?

Though we’re going to be talking about Planetary Science in this series, we should recognize the irony that “ore” is a word without any real scientific meaning. What distinguishes ore from other rock is its utility to human industry: it has elements or compounds, like gems, that we want, and that we think we can get out economically. That changes over time, and one generation’s “rock” can be another generation’s “ore deposits”. For example, these days prospectors are chasing copper in porphyry deposits at concentrations as low as 1000 ppm (0.1%) that simply were not economic in previous decades. The difference? Improvements in mining and refining, as well as a rise in the price of copper. Continue reading “Ore Formation: Introduction And Magmatic Processes”

Remembering James Lovell: The Man Who Cheated Death In Space

Many people have looked Death in the eye sockets and survived to tell others about it, but few situations speak as much to the imagination as situations where there’s absolutely zero prospect of rescuers swooping in. Top among these is the harrowing tale of the Apollo 13 moon mission and its crew – commanded by James “Jim” Lovell – as they found themselves stranded in space far away from Earth in a crippled spacecraft, facing near-certain doom.

Lovell and his crew came away from that experience in one piece, with millions tuning into the live broadcast on April 17 of 1970 as the capsule managed to land safely back on Earth, defying all odds. Like so many NASA astronauts, Lovell was a test pilot. He graduated from the US Naval Academy in Maryland, serving in the US Navy as a mechanical engineer, flight instructor and more, before being selected as NASA astronaut.

On August 7, 2025, Lovell died at the age of 97 at his home in Illinois, after a dizzying career that saw a Moon walk swapped for an in-space rescue mission like never seen before.

Smartphone Hackability, Or, A Pocket Computer That Isn’t

Smartphones boggle my mind a whole lot – they’re pocket computers, with heaps of power to spare, and yet they feel like the furthest from it. As far as personal computers go, smartphones are surprisingly user-hostile.

In the last year’s time, even my YouTube recommendations are full of people, mostly millennials, talking about technology these days being uninspiring. In many of those videos, people will talk about phones and the ecosystems that they create, and even if they mostly talk about the symptoms rather than root causes, the overall mood is pretty clear – tech got bland, even the kinds of pocket tech you’d consider marvellous in abstract. It goes deeper than cell phones all looking alike, though. They all behave alike, to our detriment.

A thought-provoking exercise is to try to compare smartphone development timelines to those of home PCs, and see just in which ways the timelines diverged, which forces acted upon which aspect of the tech at what points, and how that impacted the alienation people feel when interacting with either of these devices long-term. You’ll see some major trends – lack of standardization through proprietary technology calling the shots, stifling of innovation both knowingly and unknowingly, and finance-first development as opposed to long-term investments.

Let’s start with a fun aspect, and that is hackability. It’s not perceived to be a significant driver of change, but I do believe it to be severely decreasing chances of regular people tinkering with their phones to any amount of success. In other words, if you can’t hack it in small ways, you can’t really make it yours.

VRML And The Dream Of Bringing 3D To The World Wide Web

You don’t have to be a Snow Crash or Tron fan to be familiar with the 3D craze that characterized the rise of the Internet and the World Wide Web in particular. From phrases like ‘surfing the information highway’ to sectioning websites as if to represent 3D real-life equivalents or sorting them by virtual streets like Geocities did, there has always been a strong push to make the Internet a more three-dimensional experience.

This is perhaps not so strange considering that we humans are ourselves 3D beings used to interacting in a 3D world. Surely we could make this fancy new ‘Internet’ technology do something more futuristic than connect us to text-based BBSes and serve HTML pages with heavily dithered images?

Enter VRML, the Virtual Reality Modelling Language, whose 3D worlds would surely herald the arrival of a new Internet era. Though neither VRML nor its successor X3D became a hit, they did leave their marks and are arguably the reason why we have technologies like WebGL today.

Australia’s Space Program Finally Gets Off The Pad, But Only Barely

Australia is known for great beaches, top-tier coffee, and a laidback approach to life that really doesn’t square with all the rules and regulations that exist Down Under. What it isn’t known for is being a spacefaring nation.

As it stands, a startup called Gilmour Space has been making great efforts to give Australia the orbital launch capability it’s never had. After numerous hurdles and delays, the company finally got their rocket off the launch pad. Unfortunately, it just didn’t get much farther than that.

What Happens When Lightning Strikes A Plane?

Lightning is a powerful force, one seemingly capable of great destruction in the right circumstances. It announces itself with a searing flash, followed by a deep rumble heard for miles around.

Intuitively, it might seem like a lightning strike would be disastrous for something like a plane flying at altitude. And yet, while damage is possible, more often than not—a plane will get through a lightning storm unscathed. Let’s explore the physics at play.
