Content and cloud networks now account for three-quarters of used international bandwidth, while Google, Meta, Microsoft and Amazon own, co-own or buy capacity on a growing share of the 600-plus submarine cable systems carrying over 99 per cent of data between countries, a private map hidden below the wireless internet

Fast charging isn’t killing your battery — heat is, and your phone throttles the charger the moment it climbs past 35°C
Fast charging isn’t killing your battery — heat is, and your phone throttles the charger the moment it climbs past 35°C Every couple of months, a person in a team conversation sends out me a screenshot of a YouTube thumbnail final notice that rapid…
When you type an address into a browser, your computer asks a DNS resolver for the site’s numeric address, and the answer usually comes straight from that resolver’s cache — the 13 root server clusters at the top of the naming system get consulted only when the cache runs dry

How did a guidance computer with 4 kilobytes of memory, less than a modern greeting card chip, land Apollo 11 on the Moon in July 1969?
How did a guidance computer with 4 kilobytes of memory, less than a modern greeting card chip, land Apollo 11 on the Moon in July 1969? On 20 July 1969, around 5 mins correct into the powered descent to the lunar coating region, Neil Armstrong and Buzz…
The retina of the mantis shrimp carries twelve types of colour receptor to the human eye’s three — and yet experiments suggest it sees colour worse than we do, using the extra channels for speed instead of subtlety

When you tilt a smartphone, gravity shifts microscopic silicon fingers inside its accelerometer by only a few nanometres, changing the capacitance between them and producing the electrical imbalance the phone reads as a new direction for down

When a lightning return stroke heats a channel only centimetres wide to roughly 30,000 kelvin, about five times the temperature of the Sun’s visible surface, the air expands so violently that the pressure wave rolls across the ground as thunder

Deleting a file usually doesn’t erase it: Windows marks the space as free, HDD data can linger, and SSDs may clear it with TRIM

The Roman aqueduct at Segovia, built around the first century AD without mortar, still carried water into the 1970s, its 167 granite arches held together by nothing but the precise weight distribution of stones cut to fit each other within fractions of a millimeter.
