Domesticated Foxes Show Distinct Brain Changes Linked to Friendliness

·1 views

A study highlighted on Hacker News reports that foxes bred for friendliness display measurable changes in a specific region of the brain. The research, published via Cornell University news, compares tamer foxes with their wilder counterparts. The findings suggest that selective breeding for temperament can reshape neural structures associated with behavior. The source material available here is limited to a link and brief metadata, so the full methodology and details of the findings could not be verified.

Quarantined 34,557 Unused HTML Files, Then Found 310 Test Failures and Restored Them

A developer quarantined 34,557 HTML files in a content-collection system after a reader they had measured never opened them. The collection round that followed completed and a re-trace passed, but a full test suite comparison against a sealed baseline revealed 310 additional failures. Those failures came from other code paths, such as publish replay and provenance joins, that reopen old capture bodies and were never part of the measurement. All files were moved back the same day, which was inexpensive because they had been quarantined rather than deleted. The author concludes that a delete list must account for every reader of the data, not just one.

Python Method Builds Correct New York Day Boundaries Across DST Transitions

A DEV Community tutorial explains that a local calendar day in America/New_York does not always last 24 hours, so adding 24 hours to a UTC start can misplace events. The approach builds local midnights for adjacent dates, converts them to UTC, and compares event instants using a half-open interval. The example Python code is scoped to dates from 2010 through 2030 and includes unit tests. Tests reportedly confirm that the November 1, 2026 fallback day spans 25 elapsed hours and the March 8 spring-forward day spans 23 hours. The article also notes that a dashboard's read time is an observation instant rather than the event time.

Hong Kong employee loses about $25 million after deepfake video call impersonates executives

A finance worker at the Hong Kong office of engineering firm Arup received a message appearing to come from the company's UK chief financial officer about a confidential transaction. After joining a video call with what looked like the CFO and several familiar colleagues, the employee made 15 transfers to five bank accounts totaling about HK$200 million, roughly US$25 million. Every other participant on the call was an AI-generated deepfake, and the fraud came to light only when the employee later checked with head office. Police described it as the first time they had seen a fake multi-person video conference used this way, and Arup confirmed it was the victim in May 2024. The company said its own systems were not compromised, as the attackers exploited trust and authority rather than technical vulnerabilities.

Codex Reset alerts now reach Telegram, Discord, email and push

Codex Reset is a service that tracks OpenAI's occasional global usage-limit resets for Codex, which are usually announced on X by Thibault Sottiaux. The service reads those public posts, checks accounts it owns to confirm when a refill has landed, and sends alerts to the channel a user chooses. Alerts cover only resets, with Tibo's teases excluded, and each message type carries a status such as a probability-weighted watch or a verified reset. Telegram and Discord deliver the same alerts, while email requires users to confirm their address through a link and check spam folders if messages do not appear. The article is written by the service's own operators, who disclose their involvement and note what the service cannot do.
