The plan was to get Raspberry Pi to classify and passively detect radio frequency jamming signals. Josh would build a proof-of-concept model to demonstrate how effectively and efficiently machine learning could be used for the purpose. He selected Raspberry Pi 5 for its processing power and with an eye on planned future projects involving the AI+ HAT and Camera Module NoIR. Keen to keep build costs down, he began with an unbranded LCD that seemed to have similar capabilities to Waveshare’s. However, Josh soon found out that this was a false economy: “the unbranded screen was quite cheap and caused some electrical issues, causing Raspberry Pi to turn off when [it] was connected. Changing this for a better-quality screen fixed this issue.

Wireless communication is inherently anonymous. There is no way of knowing who transmitted a signal if they do not identify. And there is no way of knowing where that signal is transmitted from. Unless you actively track it down. KrakenSDR is a radio direction finding device that uses an array of antennas and synchronised receivers to track down the position of a given radio transmission and lead you directly to its physical location.
The Hell-system truly is a breakthrough of monumental importance. It can not be over-stated how important this invention of the pixelation is! You probably would not be reading this on a computer screen without Rudolf Hell's invention of the bitmap font. In our days, the advantage of tele-printing without the need for synchronization is not important anymore. However, in the 1920s-30s, it meant dependable and inexpensive world-wide communication.

Any electrical spark creates radio waves and acts as a transmitter. You hear sparks on a radio as interference. That's why lighting makes radios crackle, and even the tiny spark in a switch is enough to make a noise on the radio when turning on a light.
Illustrated with archival film and photographs, as well as interviews with those involved, the documentary traces the evolution of civilian involvement in radio-based intelligence during both world wars.
It was the tireless work of amateur radio enthusiasts during World War I, that initially convinced the Admiralty to establish a radio intercept station at Hunstanton. Playing an integral role during the war, technological advances meant that radio operators could pinpoint signals, thus uncovering the movement of German boats, leading to the decisive Battle of Jutland in 1916.
Wireless espionage was to play an even more important role during World War II, with the Secret Intelligence Service setting up the Radio Security Service, which was staffed by Voluntary Interceptors, a band of amateur radio enthusiasts scattered across Britain. The information they collected was interpreted by some of the brightest minds in the country, who also had a large hand in deceiving German forces by feeding false intelligence.
Despite the heavy Armenian armoured losses, the key lessons from the videos Azerbaijan has published online are not about armour. Rather, they reflect how the density of sensors on the modern battlefield is changing the balance in combined arms warfare.

With surrogacy costing up to $70,000 in the US compared to only $12,000 in India, many Western women are outsourcing pregnancy abroad. It's a multi-million dollar industry that sees rural Indians receive the equivalent of 10 years' salary. Over the course of nine months, we follow the lives of two women, who in each other seek solutions to the problems of poverty and infertility, and explore whether it's a relationship that is exploitative or mutually beneficial.
The high cost of surrogacy in Europe and the US means many Western women are outsourcing pregnancy abroad. Carolina, from Ireland, travelled to India to pay Sonal to carry her baby. The World Service's Your World followed the two women as they came to terms with the emotional costs of the surrogacy.
At 63, Pratchett — who has been diagnosed with early-onset Alzheimer's — speaks openly about causing his own death. "I believe everyone should have a good death," he tells NPR's Steve Inskeep. "You know, with your grandchildren around you, a bit of sobbing. Because after all, tears are appropriate on a death bed. And you say goodbye to your loved ones, making certain that one of them has been left behind to look after the shop." Pratchett has become an advocate for legalized assisted suicide in Britain, making him one of many voices in a global debate. Many oppose the practice for religious reasons or because they fear a slippery slope to involuntary euthanasia; but Pratchett has turned the legalization of assisted suicide into something of a personal crusade.
