Internet users advised to change passwords after 16bn logins exposed

Hacked credentials could give cybercriminals access to Facebook, Meta and Google accounts among others

Internet users have been told to change their passwords and upgrade their digital security after researchers claimed to have revealed the scale of sensitive information – 16bn login records – potentially available to cybercriminals.

Researchers at Cybernews, an online tech publication, said they had found 30 datasets stuffed with credentials harvested from malicious software known as “infostealers” and leaks.

All babies in England to get DNA test to assess risk of diseases within 10 years

Newborns will have whole genome sequencing to enable personalised healthcare that predicts and prevents illness

Every baby in England is to have a DNA screening to avoid fatal diseases and receive personalised healthcare as part of the government’s £650m investment in DNA technology, it has been reported.

Within a decade, every newborn will undergo whole genome sequencing, which assesses the risk of hundreds of diseases and is expected to form part of the government’s 10-year plan for the health service.

Social success not about who you know – it’s about knowing who knows whom

Knowledge trumps popularity in the long haul of trying to be influential, researchers say

When it comes to social climbing, it’s not who you know, or how many people you know, it’s about knowing who knows whom, research suggests.

Experts studying social connections made by first-year university students say those who ended up with the most influence were not necessarily the most popular, but those who had a good idea, early on, about who belonged to which clique or community.

[$] How to write Rust in the kernel: part 1

The Linux kernel is seeing a steady accumulation of Rust code. As it becomes more prevalent, maintainers may want to know how to read, review, and test the Rust code that relates to their areas of expertise. Just as kernel C code is different from user-space C code, so too is kernel Rust code somewhat different from user-space Rust code. That fact makes Rust's extensive documentation of less use than it otherwise would be, and means that potential contributors with user-space experience will need some additional instruction. This article is the first in a multi-part series aimed at helping existing kernel contributors become familiar with Rust, and helping existing Rust programmers become familiar with what the kernel does differently from the typical Rust project.

[$] A distributed filesystem for archival systems: ngnfs

A new filesystem was the topic of a session led by Zach Brown at the 2025 Linux Storage, Filesystem, Memory Management, and BPF Summit (LSFMM+BPF). The ngnfs filesystem is not a "next generation" NFS, as might be guessed from the name; Brown said that he did not think about that linkage ("I hate naming so much") until it was pointed out to him by Chuck Lever in an email. It is, instead, a filesystem for enormous data sets that are mostly stored offline.
