2 To 3 Cups of Coffee a Day May Reduce Dementia Risk. But Not if It's Decaf.
If you think your daily doses of espresso or Earl Grey sharpen your mind, you just might be right, new science suggests. The New York Times: A large new study provides evidence of cognitive benefits from coffee and tea -- if it's caffeinated and consumed in moderation: two to three cups of coffee or one to two cups of tea daily.
People who drank that amount for decades had lower chances of developing dementia than people who drank little or no caffeine, the researchers reported. They followed 131,821 participants for up to 43 years. "This is a very large, rigorous study conducted long term among men and women that shows that drinking two or three cups of coffee per day is associated with reduced risk of dementia," said Aladdin Shadyab, an associate professor of public health and medicine at the University of California, San Diego, who wasn't involved in the study.
The findings, published Monday in JAMA, don't prove caffeine causes these beneficial effects, and it's possible other attributes protected caffeine drinkers' brain health. But independent experts said the study adjusted for many other factors, including health conditions, medication, diet, education, socioeconomic status, family history of dementia, body mass index, smoking and mental illness.

Deepfake Fraud Taking Place On an Industrial Scale, Study Finds
Deepfake fraud has gone "industrial," an analysis published by AI experts has said. From a report: Tools to create tailored, even personalised, scams -- leveraging, for example, deepfake videos of Swedish journalists or the president of Cyprus -- are no longer niche, but inexpensive and easy to deploy at scale, said the analysis from the AI Incident Database.
It catalogued more than a dozen recent examples of "impersonation for profit," including a deepfake video of Western Australia's premier, Robert Cook, hawking an investment scheme, and deepfake doctors promoting skin creams. These examples are part of a trend in which scammers are using widely available AI tools to perpetuate increasingly targeted heists. Last year, a finance officer at a Singaporean multinational paid out nearly $500,000 to scammers during what he believed was a video call with company leadership. UK consumers are estimated to have lost $12.86bn to fraud in the nine months to November 2025.
"Capabilities have suddenly reached that level where fake content can be produced by pretty much anybody," said Simon Mylius, an MIT researcher who works on a project linked to the AI Incident Database. He calculates that "frauds, scams and targeted manipulation" have made up the largest proportion of incidents reported to the database in 11 of the past 12 months. He said: "It's become very accessible to a point where there is really effectively no barrier to entry."

Electric Cars Are Making It Easier To Breathe, Study Finds
An anonymous reader shares a report: It turns out that when fewer cars spew exhaust as they drive along, air quality improves. That's the conclusion of a new study published in The Lancet Planetary Health that looked at the effect of increased numbers of both EVs and plug-in hybrids on air pollution in California. The Golden State has by far the largest number of plug-in vehicles in the United States, and they've now reached significant numbers to have a positive impact on air quality.
Between 2019 and 2023, for every 200 EVs or plug-in hybrids added, nitrogen dioxide (NO2) levels dropped 1.1%, according to the study, which used satellite data to track those levels through the unique way NO2 absorbs and reflects sunlight. NO2 can trigger asthma attacks, cause bronchitis, and increase the risk of heart disease and stroke.

Kalshi Prediction Markets Match or Beat Traditional Forecasting Tools For Macro Indicators, NBER Study Finds
A new NBER working paper from researchers at the Federal Reserve, Northwestern's Kellogg School and Johns Hopkins finds that Kalshi -- the largest federally regulated prediction market in the U.S., overseen by the CFTC -- produces macroeconomic forecasts that match or beat those of professional forecasters and traditional financial instruments like fed funds futures.
The study compared Kalshi-implied forecasts for the federal funds rate, CPI inflation and unemployment against the New York Fed's Survey of Market Expectations and Bloomberg consensus. Kalshi's modal forecast correctly predicted the federal funds rate on the day before every FOMC meeting since 2022, something neither the survey nor fed funds futures achieved. For headline CPI, Kalshi's median and mode produced a statistically significant improvement over Bloomberg consensus.
Kalshi also fills a gap no other financial market covers: real-time probability distributions for GDP growth, core CPI, unemployment, and payrolls. The paper documented how these distributions shift in response to macro news -- positive CPI surprises moved the mean of the fed funds rate distribution four times more than negative ones. Trading volumes on the platform have grown to nearly 100 million contracts for a single FOMC meeting, supported by liquidity from Susquehanna, Citadel, and Two Sigma.

How to install KSH on FreeBSD
Installing KSH (KornShell) on FreeBSD can be done with either FreeBSD ports or the pkg command. The ports collection will download the KSH source code, compile it, and install it on the system. The pkg method is easier, and it will download a pre-compiled binary package. Hence, it is recommended for all users. KornShell (KSH) has a long history, and many older Unix systems and scripts rely on it. As a result, KSH remains relevant for maintaining and supporting legacy infrastructure. Large enterprises, especially those with established Unix-based systems, continue to use KSH for scripting and system administration tasks. Some industries where KSH is still commonly used include finance and telecommunications. While Bash has become the dominant shell in many Linux distributions, KSH still holds a significant presence in Unix-like environments, particularly in legacy systems. Therefore, installing KSH and practicing with it is worthwhile if you plan to work in such environments.

Linux Sed Tutorial: Learn Text Editing with Syntax & Examples
Sed is an acronym for "stream editor." A stream refers to a source or destination for bytes. In other words, sed can read its input from standard input (stdin), apply the specified edits to the stream, and automatically output the results to standard output (stdout). Sed syntax allows an input file to be specified on the command line. However, the syntax does not directly support output file specification; this can be achieved through output redirection or editing files in place while making a backup of the original copy optionally. Sed is one of the most powerful tools on Linux and Unix-like systems. Learning it is worthwhile, so in this tutorial, we will start with the sed command syntax and examples.

Critical Rsync Vulnerability Requires Immediate Patching on Linux and Unix systems
Rsync is a opensource command-line tool in Linux, macOS, *BSD and Unix-like systems that synchronizes files and directories. It is a popular tool for sending or receiving files, making backups, or setting up mirrors. It minimizes data copied by transferring only the changed parts of files, making it faster and more bandwidth-efficient than traditional copying methods provided by tools like sftp or ftp-ssl. Rsync versions 3.3.0 and below has been found with SIX serious vulnerabilities. Attackers could exploit these to leak your data, corrupt your files, or even take over your system. There is a heap-based buffer overflow with a CVSS score of 9.8 that needs to be addressed on both the client and server sides of rsync package. Apart from that info leak via uninitialized stack contents defeats ASLR protection and rsync server can make client write files outside of destination directory using symbolic links.

How to control the SSH multiplexing with the control commands
Multiplexing will boost your SSH connectivity or speed by reusing existing TCP connections to a remote host. This is useful when you frequently connect to the same server using SSH protocol for remote login, server management, using IT automation tools over SSH or even running hourly backups. However, sometimes your SSH command (client) will not respond or get hung up on the session when using multiplexing. Typically, this happens when your public IP changes (IPv4 to IPv6 changes when using DNS names), VPN issues, or firewall cuts connections. Hence, knowing SSH client control commands can save you time and boost your productivity when such gotchas occur.

ZFS Raidz Expansion Finally, Here in version 2.3.0
After years of development and testing, the ZFS raidz expansion is finally here and has been released as part of version 2.3.0. ZFS is a popular file system for Linux and FreeBSD. RAIDz is like RAID 5, which you find with hardware or Linux software raid devices. It protects your data by spreading it across multiple hard disks along with parity information. A raidz device can have single, double, or triple parity to sustain one, two, or three hard disk failures, respectively, without losing any data. Hence, expanding or adding a new HDD is a very handy feature for sysadmins in today's data-sensitive apps.

How to run Docker inside Incus containers
Incus and Docker both use Linux kernel features to containerize your applications. Incus is best suited when you need system-level containers that act like traditional VMs and provide a persistent developer experience. On the other hand, Docker containers are ephemeral, i.e., temporary in nature. All files created inside Docker containers are lost when your Docker container is stopped or removed unless you stored them using volumes in different directories outside Docker. Docker is created as a disposable app deployment system. Incus containers are not typically created as disposables, and data is kept inside when they are stopped. Because of the Linux kernel support nesting feature, you can run Docker inside Incus. This page explains how to run Docker inside Incus containers.
