He is actually tidier than I am (which admittedly is not saying much).

No iron curtain book list would be complete without Le Carré, and this is the book of his that sticks closest to the iron curtain. The good, the bad and the ugly of East German life are before us. The author really manages to get under the skin of what the frontier meant to ordinary people. But once he hit his stride, he imposed bizarre laws on Albanians and outlasted six ministers of the interior, the first five of whom he executed. Kempe takes the reader on a journey into the conflict, as Soviet and East German authorities attempt to solve the problem of West Berlin. It is one of the pleasures of solo travel. It is my attempt to capture what survives of the old divide both on the ground and in people’s heads. The investigation of Harry Lime’s death shows the City of Dreams in a seedy postwar light. I visited eastern Europe from 1995 onwards and found countries reeling from the end of its version of socialism. The nuclear might and conventional armed forces of all major powers were focused on that dividing line, the most likely place for a third world war to start.

Chinese surveillance manufacturer Hikvision has put in place tools to help police track protest activities.
These are just a small part of the [Chinese government’s larger campaign](https://www.theguardian.com/world/2021/sep/30/uyghur-tribunal-testimony-surveillance-china) to use technology to monitor and track members of religious and other minority groups. The document also describes “alarm methods” that include “discovery on duty”, “equipment alarm” and a call to the police. [technical document](https://open.hikvision.com/docs/docId?productId=5c67f20bb254d61550c2f63e&version=%2F658c4efa2595486c9ff140401628ff41&tagPath=%E9%99%84%E5%BD%95-%E9%99%84%E5%BD%95F%20%E6%95%B0%E6%8D%AE%E5%AD%97%E5%85%B8) also illustrates the sheer breadth of data on individuals the company enables its customers to track. That would also be the case for the “Falun Gong” alarm. The company’s website also included alarms for “religion” and “Falun Gong” – a spiritual movement banned in Hikvision pitches its cloud platform, called Infovision IoT, as a means to “provide intelligent public security decision-making and services” for police in order to alleviate “uneven allocation of resources, heavy workload, inability to share data”, [developing the capabilities](https://www.nytimes.com/2019/04/14/technology/china-surveillance-artificial-intelligence-racial-profiling.html) to detect Uyghurs and other minorities. So I am concerned about how technology can facilitate the tracking of repressed groups.” Chinese police can set up “alarms” for various protest activities using a software platform provided by Hikvision, a major Chinese camera and surveillance manufacturer, the Guardian has learned. “It raises significant freedom of assembly and freedom of religion concerns,” Rollet said. The US government has long had its sights set on Hikvision. The findings come a month after mass protests against the country’s zero-Covid policies erupted across China.

She loved to travel, too, especially visiting her son, Roy, and his partner, Jeanette, in New Zealand. She also enjoyed the songs of Michael Bublé, Frank Sinatra and Barry Manilow, and relished singing in church. After leaving school, she joined the North Western Electricity Board as a comptometer operator.
Research found greater chances of multiple chronic illnesses in people living in polluted areas.
[Recent analysis](https://www.cambridge.org/core/journals/journal-of-economic-history/article/atmospheric-pollution-health-and-height-in-late-nineteenth-century-britain/45222CE345F6FC027F2AF2EC4018D913) of first world war army records found that air pollution had been reducing the height and health of soldiers who grew up downwind of areas of intense coal use.

Putting this another way, the A subsequent Ministry of Health [report](https://www.worldcat.org/title/891783042) reviewed past death records and found that smogs had been killing people over the previous 80 years.
