Thanks in part to the formation of high-profile groups such as #Scientist #Rebellion
now many scientists join protests,
even getting arrested.
Research in the journal Nature revealed 90% of climate scientists in 2021 said they had been involved in some form of public engagement.
But climate …

#Museums join the #Fediverse:
"Ultimately the goal is to expand and broaden the “surface area of interests” allowing us to reach a broader audience and increasing awareness of the Museum’s programming and offerings. To that end having a platform-agnostic means by which our visitors can subscribe…

Holding Hands with the "Fediverse" – ActivityPub at SFO Museum
SFO Museum has joined the “Fediverse”. We have begun to operate a series of automated “bot” accounts that are published using the ActivityPub protocols and that can be subscribed to from any client, like Mastodon, that supports those standards. These are automated, low-frequency, accounts and they currently only support a limited set of interactions: Accounts can be followed or unfollowed, individual posts can be “liked”, “boosted” or replied to but those replies will not be ans…

We need to see leadership for a sustainable future now.

Dynamic Client Clustering, Bandwidth Allocation, and Workload Optimization for Semi-synchronous Federated Learning
Federated Learning (FL) revolutionizes collaborative machine learning among Internet of Things (IoT) devices by enabling them to train models collectively while preserving data privacy. FL algorithms fall into two primary categories: synchronous and asynchronous. While synchronous FL efficiently handles straggler devices, it can compromise convergence speed and model accuracy. In contrast, asynchronous FL allows all devices to participate but incurs high communication overhead and potential mod…

Atlas-X Equity Financing: Unlocking New Methods to Securely Obfuscate Axe Inventory Data Based on Differential Privacy
Banks publish daily a list of available securities/assets (axe list) to selected clients to help them effectively locate Long (buy) or Short (sell) trades at reduced financing rates. This reduces costs for the bank, as the list aggregates the bank's internal firm inventory per asset for all clients of long as well as short trades. However, this is somewhat problematic: (1) the bank's inventory is revealed; (2) trades of clients who contribute to the aggregated list, particularly those deemed la…

Capturing the Variability of the Nocturnal Boundary Layer through Localized Perturbation Modeling
A single-column model is used to investigate regime transitions within the stable atmospheric boundary layer, focusing on the role of small-scale fluctuations in wind and temperature dynamics and of turbulence intermittency as triggers for these transitions. Previous studies revealed abrupt near-surface temperature inversion transitions within a limited wind speed range. However, representing these transitions in numerical weather prediction (NWP) and climate models is a known difficulty. To sh…

Marriott quietly admits it did not encrypt certain user data impacted by a 2018 breach, after arguing in court encryption was used so lawsuits should be tossed (Evan Schuman/CSO)

Marriott admits it falsely claimed for five years it was using encryption during 2018 breach
Marriot revealed in a court case around a massive 2018 data breach that it had been using secure hash algorithm 1 and not the much more secure AES-1 encryption as it had earlier maintained.

I have some travels coming up - non stop till mid August - so followup for part 6 when I can.
