As a followup to my mastodon account (see this post), I’ve also created an experimental Blue Sky account. I’ve still no idea how long they’ll last.

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.
Happy 30th Birthday ‘Anglosphere’!
So here’s something of an oddity; the Oxford English Dictionary thinks the word ‘Anglosphere’ is a mere thirty years old this month.
Converting Video to Image Sequences with ffmpeg
Another little aide-memoire masquerading as a blog post; the specific incantation required to turn a video into a named sequence of images with ffmpeg is…
ffmpeg -i <path to source video> -vf fps=<frames per second> <output directory/basename->%d.png…where…
<path to source video> is the path to the video file in question.
<frames per second> is the number of frames per second of footage to extract. This can be less than 1 if you wish to extract at a lower rate than one frame per second.
<output directory/basename->%d.png is a composite instruction to create files in the directory ‘output directory’, for these files to have the prefix ‘basename-‘, and for these files to have an incrementing count appended to the end. It also specifies that the output files should be in the ‘.png’ format.
Linkspam: How the BFI uses 3D printing to help maintain it’s archive machinery
A nice short on how the British Film Institute uses 3D printing to maintain and improve it’s archiving tech.
Period Sites with Period Browsers – Machine No. 131
It’s time to add another machine to Period Sites with Period Browsers – this time it’s an instance of Windows 95 with Attachmate’s Emissary 2.0. See it’s first run here!
Archivery: The Oldest Pages in the Wayback Machine
This is something I’ve been meaning to write up for a little while and, with the success of the Internet Archive’s recovery from it’s attack, it makes sense to do so now.
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.
York Historic Environment Record Blog RSS Feed
So the City of York Historic Environment Record department has a an interesting, if infrequently updated, blog covering archeology and historic conservation efforts in York.
Now my preferred way of reading blogs – especially those which are not frequently updated – is to stick that particular blog’s RSS feed in my reader and to let the updates come to me. Unfortunately the YHER Blog doesn’t have an obvious link to a feed, but, after a little poking around at the page’s HTML, I’ve managed to find a URL that seems to work: York Historic Environment Record Blog RSS Feed.
And that should perfect to be fed into your reader of choice!
Linkspam: MIT fed an AI data from Reddit, and now it only thinks about murder
Apparently the hot new things is to train your A.I. on Reddit – something that doesn’t have a particularly great track record…
