Anyone in #archaeology out there who has used, or knows about seismic detection of buried buildings?

The challenge: there's a church, St. Ann's, in Bethesda, north Wales, that was buried under slate waste in the mid-19th century. It's since been a topic of fascination because there are no reliable depictions of it, though there is one graffito that could be it.

The depth of burial is not great, probably 15-20m. I guess the haphazard, flat slate surfaces making up the waste could be a problem?

So, I’ve reading up on lossless audio compression yesterday and found that based on http://www.audiograaf.nl/losslesstest/revision%206/Average%20of%20CDDA%20sources.pdf these are the most efficient free-to-use lossless audio codecs (in order):

Notably that list doesn’t include expensive proprietary codecs like DTS-HD, MLP (Dolby TrueHD), MPEG-4 SLS. All codecs listed above are free-to-use.

What bogs my mind from that list though is two first entries: OptimFROG and LA.

Both were each developed by a single person in their spare time and have to-this-date unbeaten compression ratios in the free-to-use space. Both are also highly proprietary and have never been reverse engineered.

⚠️ Notepad++ Hijacked by State-Sponsored Hackers

｢ The exact technical mechanism remains under investigation, though the compromise occured at the hosting provider level rather than through vulnerabilities in Notepad++ code itself. Traffic from certain targeted users was selectively redirected to attacker-controlled served malicious update manifests ｣
