Leaked DarkSword iPhone spyware lowers bar for mass exploitation
FCC bans import of all new foreign-made routers, Foster City officially declares state of emergency following attack, German federal police visited Windchill and FlexPLM users in the wee hours to warn them of a severe flaw, Scioto County employees fell victim to phishing, much more

A reporter writes about a visit from the FBI in 2020, following his story about a hack, and the long-term personal impact, along with eroding press freedoms (Zack Whittaker/~this week in security~)

FBI agents visited my home about an article I wrote, and now I can't go to Mexico
Mexico formally requested the FBI's help in seeking answers about one of my stories. Having federal agents on my doorstep sparked my own years-long effort to pry information out of the FBI to explain why it came to my house to begin with.

Im using case_when() quite a lot, case_match() is new to me: #rstats

A general vectorised switch() — case_match
This function allows you to vectorise multiple switch() statements. Each case is evaluated sequentially and the first match for each element determines the corresponding value in the output vector. If no cases match, the .default is used. case_match() is an R equivalent of the SQL "simple" CASE WHEN statement. Connection to case_when() While case_when() uses logical expressions on the left-hand side of the formula, case_match() uses values to match against .x with. The following two statement…

AVFTCN 040 – Returning From A Hiatus, and Plans for 2026
I'm back. After a self-imposed hiatus for most of 2025, I'm returning to something I've been deeply missing... writing and speaking. If you've been following me for any length of time, you know that not writing or speaking is, for me, a kind of pressure that builds and builds until I am ready to explode. 🤯 So what happened? The short version: my role at the…

"By almost every measure, life is better than ever."
However, we often feel otherwise. And some people want us to believe otherwise.
The discrepancy is explained by Negativity Bias, Nostalgia Bias, and the slow but steady long-term overall improvements being shadowed by temporary setbacks.
Excellent explanation by Adrian Krebs.

A New Mexico jury finds that Meta violated state laws by failing to safeguard its platforms from child predators and orders it to pay $375M in damages (Jonathan Vanian/CNBC)

Meta must pay $375 million for violating New Mexico law in child exploitation case, jury rules
Jury reaches a verdict in New Mexico trial in which the state's attorney general alleged that Meta failed to safeguard its family of apps from child predators.

RFK Jr. trying again to explain the Trump-'math' of calculating percentages and again failing hopelessly.
He can't even give a correct example for an increase (which Trump usually would calculate correctly).
"$100 --> $600 is a 600% rise"
No you moron, it is a 500% rise!!

A minimal wake-vortex model explains formation flight of flapping birds

Abstract: Collective patterns of motion emerge across biological taxa: insects swarm, fish school, and birds flock. In particular, large migratory birds form strikingly ordered V-shaped formations, which experiments and direct numerical simulations have demonstrated provide substantial energetic benefits during long-distance flight. However, the precise aerodynamic and morphological mechanisms underlying these benefits remain unclear. In this work, we develop a reduced-order model of the wake-vortex interactions between two flapping birds flying in tandem. The model retains essential unsteady flapping dynamics while remaining computationally tractable. By optimizing over a six-dimensional state space, which comprises the follower's three-dimensional relative position and three independent flapping parameters, we identify the energetically optimal leader-follower configuration of northern bald ibises. The predicted optimum agrees quantitatively with live-bird measurements. Because of its simplicity, the model allows for direct interrogation of the physical mechanisms responsible for this optimum. In particular, it isolates precisely how the follower's wing kinematics interact with the leader's wake to enhance aerodynamic efficiency. The model predicts an 11% reduction in total mechanical power for a follower in formation flight -- consistent with experimental estimates -- and shows that this saving arises from reductions in both induced and profile power, dominated by decreased profile power enabled primarily through reduced flapping amplitude and, secondarily, reduced upstroke flexion. These results provide a mechanistic explanation for the structure of V-formations and offer new insight into the aerodynamic principles governing collective flight.

anyone know an equivalent drop-in replacement for the Humirei HS-1101/HS-1100 humidity sensor? the 1100s aren’t being made at all anymore, and only clones of the 1101 are being made. i have no issue with using clone components (the one I’m replacing is a clone) but this general style of sensor seems incredibly fragile and prone to falling out of calibration. (the one I’m replacing had, and then broke when I tried to take it apart to clean/investigate it)
