Tío, no me fío, eso de forzar JavaScript o apps huele a control encubierto, aunque lo vendan como práctico.

Weekly Update from the Open Journal of Astrophysics – 18/10/2025
It’s time once again for the usual Saturday update of the week’s new papers at the Open Journal of Astrophysics. Since the last update we have published four more papers, which brings the number in Volume 8 (2025) up to 156, and the total so far published by OJAp up to 391.
I’d like to encourage people to follow our feed on the Fediverse via Mastodon (where I announce papers as they are published, including the all-important DOI) so this week I’ll include links to each announcement there.
The first paper to report is “Shot noise in clustering power spectra” by Nicolas Tessore (University College London, UK) and Alex Hall (University of Edinburgh, UK). This was published in the folder Cosmology and NonGalactic Astrophysics on Tuesday October 14th 2025. This presents a discussion of the effects of ‘shot noise’, an additive contribution due to degenerate pairs of points, in angular galaxy clustering power spectra. Here is a screen grab of the overlay:

This paper discusses the abundance of large arc-like structures formed in the standard cosmological model, with reference to the “Giant Arc” identified in MgII absorption systems. It was published on Wednesday October 15th in the folder Cosmology and NonGalactic Astrophysics. The overlay is here:

The third paper this week, published on Monday 6th October, is “Detecting wide binaries using machine learning algorithms” by Amoy Ashesh, Harsimran Kaur and Sandeep Aashish (Indian Institute of Technology, Patna, India). This was published on Friday 17th October (yesterday) in the folder Astrophysics of Galaxies. It presents a method for detecting wide binary systems in Gaia data using machine learning algorithms.

Price (University College London, UK), Davide Piras (Université de Genève, CH), Alessio Spurio Mancini (Royal Holloway, London, UK) and Jason D. McEwen (University College London). This one was also published on Friday 17th October, but in the folder Instrumentation and Methods for Astrophysics; it presents a new method for estimating Bayesian evidence for use in model comparison, illustrated with a cosmological example.

I would like an optional algoritme in Mastodon that autmatically adds an alt-text to a picture, which i can ofcourse edit if i want, i think that would increase accessability. I know that there are bots that do this, but that is different in user experience.

今朝、自鯖のストレージがやけに膨れているので、以下のコマンド実行。
RAILS_ENV=production bundle exec bin/tootctl xxx で xxxの内容は次の通り。
media remove
emoji purge
media remove --prune-profiles
media remove --remove-headers
preview_cards remove
statuses remove
media remove-orphans
accounts prune
これで、#Mastodon 関係で 90G → 67Gに縮小。
他鯖のdata cache が大きい。
ちなみに、おひとり様の自鯖は
#さくらインターネットの #VPS で、
仮想3Core/2GB メモリー/HDD 200GB のスペック（現在は販売していないかも）で、外部ストレージなしで運用しています。
ストレージは通常 200Gの半分くらいで推移しています。
ただし、お気に入りは５日以前のものはお気に入り解除して運用。

What’s with the recent inflow of porn bots on mastodon.social? They abuse hashtags such as “Taiwan”, “Switzerland”, etc.
Anyone else noticed?

Mit den verschiedenen Anpassungsmöglichkeiten der Tableiste, ist #MonaApp (auf #iOS) für mich wirklich die beste #App für die Bedienung meines #Mastodon-Accounts.
Toll gemacht!

One nice thing about not running my own Mastodon instance anymore is that I don't have to worry about object storage prices
