Train to Busan and the decade that transformed Korean cinema
Ten years after its release, the zombie thriller remains a case study in how local social anxieties propelled Korean film to international prominence.

In the ever-evolving landscape of modern warfare, where drones have become pivotal players, a Ukrainian tech company is making waves in its quest to outmaneuver Russian electronic warfare.
Sine.Engineering, a cutting-edge drone technology firm, is on a mission to revolutionize how operators control and communicate with unmanned systems, striving to outsmart the digital battlefield complexities posed by one of the world’s most formidable military powers.
In a war where GPS signals can be jammed into oblivion, Sine.Engineering is rewriting the rule book.
Their innovation doesn’t rely on the cumbersome hard-wiring seen in fiber-optic drones.
Instead, they’re harnessing the past’s wisdom, akin to the old-school “dead reckoning” used by pilots before GPS was a twinkle in the sky.
This technique, however, is receiving a 21st-century makeover, fused with time-of-flight calculations and signals from a specialized communication module, all designed to keep drones on track when satellites are rendered useless.
At the helm of this technological renaissance is CEO Andriy Chulyk, a visionary who understands that the battlefield is a relentless testing ground.
“You should try and test different kinds of things,” Chulyk tells us, underscoring the importance of adaptability and constant feedback from the Ukrainian military.
The stakes are enormous.
Russian electronic warfare might be a formidable opponent, but Ukrainian drone operators are stepping up their game, employing electronic warfare tactics of their own.
It’s a cat-and-mouse game, with Sine.Engineering’s data chips—no bigger than an SD card—playing a crucial role in navigating the contested airspace.
But perhaps the most thrilling development on the horizon is Sine’s exploration of drone swarming.
Imagine a symphony of uncrewed aerial vehicles, guided by a single conductor, capable of overwhelming adversaries with sheer numbers.
This is not just science fiction; it’s a glimpse into the future of military operations.
Yet, ambition is not without its hurdles.
The challenge lies in the vast amounts of data required for these drones to navigate with precision.
Artificial intelligence could be a game-changer, although it has yet to make its battlefield debut in Ukraine.
The vision, however, is tantalizing—a drone that continues its mission even when communication is severed.
While fiber-optic drones offer a reliable connection, they are not without limitations.
Their range is restricted, and environmental obstacles can impede their path.
Sine.Engineering’s approach, favoring non-GPS systems, might just be the key to unlocking the full potential of drone warfare.
As the conflict in Ukraine rages on, Sine.Engineering is not just adapting to the challenges; they’re rewriting the rules, proving that innovation and resilience can outpace even the most sophisticated electronic adversaries.
In this high-stakes game of drones, the Ukrainian spirit of ingenuity and determination shines bright.
