The pdf.tocgen tool consists of three parts: pdfxmeta extracts metadata from PDF files, pdftocgen generates a table of contents based on the metadata, and pdftocio imports the contents into the PDF document. An example using Paul Graham’s “On Lisp” demonstrates these steps. Users create a recipe file using pdfxmeta and then use pdftocgen to generate […]
Physicists have finally achieved the long-awaited “thorium transition” using lasers, paving the way for extraordinary high precision technologies like nuclear clocks. The success of manipulating thorium atomic nuclei opens up possibilities for revolutionary applications in time measurement and fundamental physics. Despite the challenges of finding the precise energy transition within thorium nuclei, the team led […]
GRU Unit 29155, known for its deadly operations, made headlines after blowing up ammunition warehouses in Czechia with the help of Elena and Nikolai Šapošnikov, a family of deep-cover spies turned arms dealers. The couple, operating outside diplomatic cover, ran a hotel in Greece that served as a safehouse for the notorious assassination squad. The […]

In the 1940s, German U-Boats were causing chaos in the Atlantic, prompting inventor Geoffrey Pyke to propose a giant, unsinkable aircraft carrier made of ice, called Project Habakkuk. Pyke developed pykrete, a mixture of wood and ice, as a stronger alternative. Despite setbacks and incidents, a 1,000-ton prototype was built on Patricia Lake in Canada, […]
The NASA/ESA/CSA James Webb Space Telescope recently captured stunning infrared images of the Horsehead Nebula, showcasing unprecedented detail and complexity. The iconic nebula, also known as Barnard 33, is located about 1300 light-years away and is illuminated by a nearby hot star. It is estimated to have about five million years left before it disintegrates. […]
