ChatControl Gets Coup-De-Grace

Possibly the biggest privacy story of the year for Europeans and, by extension the rest of the world, has been ChatControl. Chatcontrol is a European Union proposal backed by Denmark for a mandatory backdoor in all online communications. As always with these things, it was touted as a think-of-the-children solution to online child abuse material, but as many opposed to it have warned, that concealed far more sinister possibilities. For now, it seems we can breathe easily as the Danes are reported to have formally backed away from the proposal after it was roundly condemned by the German government, sending it firmly into the political wilderness.

Hackaday readers are likely vastly more informed on this matter than many of the general public, so you’ll have no need for a primer on the obvious privacy and security concerns of such a move. From our point of view, it also suffered from the obvious flaw of being very unlikely to succeed in its stated aim. Even the most blinkered politician should understand that criminals would simply move their traffic to newly-illegal encrypted forms of communication without government backdoors. Perhaps it speaks volumes that it was the Germans who sounded its death-knell, given that state surveillance on that level is very much within living memory for many of them.

The mood in European hackerspaces has been gloomy of late on the subject, so it’s something of a cause for celebration on the continent. If only other governments on the same side of the Atlantic could understand that intrusive measures in the name of thinking of the children don’t work.

The Channel Crossing Bridge That Never Was

Full marks for clarity of message. Credit: Euro Route materials

When the Channel Tunnel opened in 1994, the undersea rail link saw Britain grew closer to the European mainland than ever before. However, had things gone a little differently, history might have taken a very different turn. Among the competing proposals for a fixed Channel crossing was a massive bridge. It was a scheme so audacious that fate would never allow it to come to fruition.

Forget the double handling involved in putting cars on trains and doing everything by rail. Instead, the aptly-named Euro Route proposed that motorists simply drive across the Channel, perhaps stopping for duty-free shopping in the middle of the sea along the way.

Hackaday Links: February 9, 2025

January 9 ended up being a very expensive day for a Culver City, California man after he pleaded guilty to recklessly operating a drone during the height of the Pacific Palisades wildfire. We covered this story a bit when it happened (second item), which resulted in the drone striking and damaging the leading edge of a Canadian “Super Scooper” plane that was trying to fight the fire. Peter Tripp Akemann, 56, admitted to taking the opportunity to go to the top of a parking garage in Santa Monica and launching his drone to get a better view of the action to the northwest. Unfortunately, the drone got about 2,500 meters away, far beyond visual range and, as it turns out, directly in the path of the planes refilling their tanks by skimming along the waters off Malibu. The agreement between Akemann and federal prosecutors calls for a guilty plea along with full restitution to the government of Quebec, which owns the damaged plane, plus the costs of repair. Akemann needs to write a check for $65,169 plus perform 150 hours of community service related to the relief effort for the fire’s victims. Expensive, yes, but probably better than the year in federal prison such an offense could have earned him.

Moving Power Grids In A Weekend, The Baltic States Make The Switch

A significant event in the world of high-power electrical engineering is under way this weekend, as the three Baltic states, Lithuania, Latvia, and Estonia, disconnect their common power grid from the Russian system, and hook it up to the European one. It’s a move replete with geopolitical significance, but it’s fascinating from our point of view as it gives a rare insight into high voltage grid technology.

There are a few news videos in the air showing contactors breaking the circuit, and even a cable-cutting moment, but in practice this is not as simple a procedure as unplugging an appliance from a wall socket. The huge level of planning that has gone into this move is evident in the countrywide precautions in case of power loss, and the heightened security surrounding the work. As we understand it at the moment the three countries exist as a temporary small grid of their own, also isolating the Russian exclave of Kaliningrad which now forms its own grid. The process of aligning the phase between Baltic and European grids has been under way overnight, and an online monitor shows significant frequency adjustments during that time. At some point on Sunday a new connection will be made to the European grid via Poland, and the process will be completed. We imagine that there will be a very relieved group of electrical engineers who will have completed their own version of a Moon landing when that has happened.

If you happen to live in either region, there’s still some time to watch the process in action, by monitoring the supply frequency for yourself. It’s not the first time that geopolitics have affected the European grid, as the continent lost six minutes a few years ago, and should you Americans think you are safe from such problems, think again.

A Hacker’s Travel Guide To Europe

This summer, I was pleasantly surprised when a friend of mine from Chicago turned up at one of the hacker camps I attended. A few days of hanging out in the sun ensued, doing cool hacker camp stuff, drinking unusual beverages, and generally having fun. It strikes me as a shame that this is such a rare occurrence, and since Hackaday is an American organisation and I am in a sense writing from its European outpost, I should do what I can to encourage my other friends from the USA and other parts of the world to visit. So here I’m trying to write a hacker’s guide to visiting Europe, in the hope that I’ll see more of you at future camps and other events.

It’s Intimidating. But Don’t Worry.

Danish road sign: "Se efter tog", or according to Google Translate: "Look for trains".
Yes. We’d find this intimidating, too. Bewitchedroutine, Public domain.

First of all, I know that it’s intimidating to travel to an unfamiliar place where the language and customs may be different. I’m from England, which sits on a small island in the North Atlantic, and believe it or not it’s intimidating for us to start traveling too. It involves leaving the safety of home and crossing the sea whether by flight, ferry, or tunnel, and that lies outside one’s regular comfort zone.

Americans live in a country that’s almost a continent in its own right, so you can satisfy your travel lust without leaving home. Thus of course the idea of landing in Germany or the Netherlands is intimidating. But transatlantic flights are surprisingly cheap in the scheme of international travel because of intense competition, so I’m here to reassure you that you can travel my continent ‘s hacker community without either feeling out of your depth, or breaking the bank.

The State Of High Speed Rail, And A Look To Tomorrow

In the 21st century, the global transportation landscape is in shift. Politicians, engineers, and planners all want to move more people, more quickly, more cleanly. Amid the frenzy of innovative harebrained ideas, high-speed rail travel has surged to the forefront. It’s a quiet achiever, and a reliable solution for efficient, sustainable, and swift intercity and intercountry transit.

From the thriving economies of Europe and Asia to the burgeoning markets of the Middle East and America, high-speed rail networks are being planned, expanded, and upgraded whichever way you look. A combination of traditional and magnetic levitation (maglev) trains are being utilized, reaching speeds that were once the stuff of science fiction. As we set our sights towards the future, it’s worth taking a snapshot of the current state of high-speed rail, a field where technology, engineering brilliance, and visions of a greener tomorrow converge.

As Europe Goes To LEDs, Scientists Worry

There was a time when street lighting means someone had to go light the lamps. Electricity changed that, but street and outdoor lighting has been quietly going through a new revolution: LEDs. The problem, though, is that LEDs provide what scientists call “broad white” light and there are concerns about the impact the unnatural lighting will have on ecosystems, including people and animals.

Of course, the first step in worrying about something is to measure it. You would think that satellites would have a bird’s-eye view of the nighttime lighting landscape, and, of course, they do. But most of the imagery isn’t suitable for looking at the spectrum of wavelength data scientists need to quantify what they call ALAN — Artificial Light at Night.

The ISS imaging is, however, sufficient. Using special data techniques, they were able to track the adoption of LEDs over sodium lights and other technologies between 2012-2013 and 2014-2020 across Europe. For example, in the title image, you can see Belgium with an orange tint indicating low-pressure sodium lights. The Netherlands, France, and the UK have a more yellow hue, indicating high-pressure sodium lamps. Germany is more of a blue color due to fluorescent and mercury vapor bulbs.
