Linkspam: Using Machine Learning for Geoglyph Detection

PNAS has an interesting paper on using AI and Machine Learning to try and identify new Nazca Pampa geoglyphs in the Peruvian Nazca Desert. It’s a fun little lunchtime skim with a few nice images of some of the newly found geoglyphs.

PNAS: AI-accelerated Nazca survey nearly doubles the number of known figurative geoglyphs and sheds light on their purpose

Linkspam: Bop Spotter

Bop Spotter is an interesting little curio; take an Android phone, set it to run Shazam on a loop, and then hide it somewhere (in this case San Franciscos’s Mission district) with a solar panel attached and suddenly you have the the culture-tasting equivalent of ShotSpotter, generating the unique soundtrack to a particular location. San Franciscos’s Mission is, of course, a very particular environment with a distinct feel too it, so it’d be interesting to see how it would contrast with other locations around the world – though I do suspect that most would end in the brief bang of a controlled explosion.

Linkspam: Starring the Computer

Starring the Computer is a fun – if somewhat geeky – site recording the use of various computers in films and television. As long with the usual suspects – such as the Apple Macintosh SE and the Commodore 64 – they have some more obscure devices, such as the Thinking Machines CM-1 pictured below. It is really worth a look.

Retrieving the Time Machine Estimated Full Backup Size

Another handy little magic spell for MacOS Sonoma’s Time Machine tool is…

log show --predicate 'subsystem == "com.apple.TimeMachine"' --info | grep "Estimated full backup will"

…which – when entered into a suitable Terminal instance – will print out Time Machine’s recent estimates of the storage costs of a full backup…
