I like to play around as an anonymous commenter in online newspaper columns. If you point out the biases of #AI systems, the comment gets deleted because it is considered too polemical.
The comment was addressing an article about AI in public service and the use in refugee applications đź«Ł

A quick chat with ChatGPT itself: asked about bias in training and inference, it agrees. It's not traceable; "the exact causal pathways inside a deep neural network remain largely opaque to human understanding." It's never fully decodable. Not that we can trust this very output.

“Many questions remain about the fund-raising for this project,
including the amount of each contribution,
the agreement reached with each contributor,
what promises may have been or may yet be made in exchange for what presumably will be substantial contributions,
and why the White House chose to allow donors to remain anonymous,”
Mr. Blumenthal, the ranking Democrat on the Senate Permanent Subcommittee on Investigations, wrote in letters to several donors

Hegseth abruptly summons top military commanders to meeting next week
Defense Secretary Pete Hegseth has summoned hundreds of generals and admirals to a base in northern Virginia for a sudden meeting next week. The directive doesn't offer a reason for the gathering Tuesday of senior commanders of the one-star rank or higher and their top advisers. Confirmation comes from three people familiar with the matter who weren't authorized to publicly discuss the sensitive plans and spoke on condition of anonymity. The Pentagon’s top spokesman confirms that Hegseth “w…

Eliminating Exponential Key Growth in PRG-Based Distributed Point Functions
Distributed Point Functions (DPFs) enable sharing secret point functions across multiple parties, supporting privacy-preserving technologies such as Private Information Retrieval, and anonymous communications. While 2-party PRG-based schemes with logarithmic key sizes have been known for a decade, extending these solutions to multi-party settings has proven challenging. In particular, PRG-based multi-party DPFs have historically struggled with practicality due to key sizes growing exponentially…

Secret Leader Election in Ethereum PoS: An Empirical Security Analysis of Whisk and Homomorphic Sortition under DoS on the Leader and Censorship Attacks
Proposer anonymity in Proof-of-Stake (PoS) blockchains is a critical concern due to the risk of targeted attacks such as malicious denial-of-service (DoS) and censorship attacks. While several Secret Single Leader Election (SSLE) mechanisms have been proposed to address these threats, their practical impact and trade-offs remain insufficiently explored. In this work, we present a unified experimental framework for evaluating SSLE mechanisms under adversarial conditions, grounded in a simplified…
