Big Oil isn’t part of the clean energy push, despite its claims, study shows
A new study that mapped the portfolios of the world’s 250 biggest oil and gas companies found their deployment of renewable energy is paltry: they’re responsible for just 1.42% of the global renewable energy capacity in operation. Despite announcing ambitious plans to embrace renewables, a mere 0.1% of the primary energy they produce comes from […]

Where should we recommend events & community host long videos that isn't YouTube?
* Vimeo - paid, embeds work, recently acquired is a bad sign
* @… - free, no embeds
* BunnyCDN - paid, lots of options including APIs, no embeds
* Peertube - self-hosted, no embeds

Video on Demand (VOD) options for ATProto
We were discussing video hosting for later playback aka “video on demand” VOD for videos from ATProto events to embed on web pages and attach to posts. Note: Stream.place is great for streaming! VOD is on the roadmap. What options are there for storing and playback of videos? Hosted Vimeo Has been a good platform for many years. Recently bought by Bending Spoons, so likely going to get worse. Might be OK for the short term. Example from EuroSky Live “showcase” page: Videos are …

Short-Lived Radioisotopic enrichment from AGB interlopers in low-mass star-forming regions
The decay of Short-Lived Radioisotopes (SLRs) can be a significant source of heating early in protoplanetary systems, though how a protoplanetary disk becomes enriched with these SLRs far above the galactic background level remains an open question. Observational evidence suggests that this enrichment occurs during the period from when the disk forms to when it progresses into a protoplanetary system, and is homogenous throughout the resultant planetary system. Whilst SLRs such as 26Al and 60Fe…

Rethinking Portfolio Risk: Forecasting Volatility Through Cointegrated Asset Dynamics
We introduce the Historical and Dynamic Volatility Ratios (HVR/DVR) and show that equity and index volatilities are cointegrated at intraday and daily horizons. This allows us to construct a VECM to forecast portfolio volatility by exploiting volatility cointegration. On S&P 500 data, HVR is generally stationary and cointegration with the index is frequent; the VECM implementation yields substantially lower mean absolute percentage error (MAPE) than covariance-based forecasts at short- to mediu…

Ich lade fleißig Schritt für Schritt meinen alten Covid-Algebra Kurs auf Peertube hoch. Die Videos sind getaggt mit #mathe und #algebra und ohne weiteres Zutun booset der @… das dann immer automatisch auf Mastodon. Da ist schon einiges implementiert im Fediverse.
Ich will alles wissen was hier geht!
Soll ich mein Zeug nur noch auf PeerTube hochladen? Oder später auch noch auf YT zweitverwerten?

Ich habe ein Short gemacht, wie ich die #Tafel wische.
Das gibt's dann jetzt schon auf #PeerTube und erst heute nachmittag auf YT 🙃 #sillysunday https://tube.mathe.social/w/mffXSukASaAz3unRRWEAX4
