Rest day - wife wanted to visit the sports shop again (where we brought the hiking shoes). This time I bought a new #hiking trouser as mine starts to show signs of its age slowly...
This vacation starts to be expensive 🤔
But I admit that I thought about getting a new trouser since quite a while anyways.

Sanctions Imposed on DPRK IT Workers Generating Revenue for the Kim Regime
WASHINGTON — Today, the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) sanctioned Song Kum Hyok, (Song), a malicious cyber actor associated with the sanctioned Democratic People’s Republic of Korea (DPRK) Reconnaissance General Bureau (RGB) hacking group Andariel.Song facilitated an information technology (IT) worker scheme in which individuals, often DPRK nationals working from countries such as China and Russia, were recruited and provided with falsified ident…

Cybercriminals are using AI to execute highly targeted attacks at scale, causing people to unwittingly send money and sensitive information or simply open themselves up to theft.
Hackers are now able to rent generative AI large language models created in the underground cybercrime community to help formulate text-based scams.
But just as generative AI is enhancing and scaling social engineering attacks, so too is it giving defenders a leg up.

The hacking underworld has removed all of AI's guardrails, but the good guys are closing in
Fake Taylor Swift ads and malicious QR codes are just some of the newest ways cybercriminals are using AI as the cat-and-mouse cybersecurity game heats up.

Large Language Model Hacking: Quantifying the Hidden Risks of Using LLMs for Text Annotation
Large language models (LLMs) are rapidly transforming social science research by enabling the automation of labor-intensive tasks like data annotation and text analysis. However, LLM outputs vary significantly depending on the implementation choices made by researchers (e.g., model selection, prompting strategy, or temperature settings). Such variation can introduce systematic biases and random errors, which propagate to downstream analyses and cause Type I, Type II, Type S, or Type M errors. W…

i saw this in a krugman post:
Recently the West Side Rag, my ultra-local news source, ran an article titled “The Upper West Side: A Neighborhood for Independent Minds.” Lots of interesting history, but frankly my first reaction was “Yeah, independent minds who can afford to pay $1600 a square foot for housing.”
meanwhile my next door neigbor just got halfway-to-new-york-ridiculous per sq ft. in ann arbor for pete's sake

Hey #FOSS friends! 🚴‍♂️
I just got into biking again as an adult, and I’m loving it!
Now I’m on the hunt for a simple open source app to track how far I ride. Bonus points if it’s on GitHub, if not, at least F-Droid works. If there’s nothing bike-specific, I’m cool with any travel or hiking tracker too.
I use a Pixel 9a with GrapheneOS.
Any recs? Drop ’em here! 🙌

Overcoming logarithmic singularities in the Cahn-Hilliard equation with Flory-Huggins potential: An unconditionally convergent ADMM approach
The Cahn-Hilliard equation with Flory-Huggins potential serves as a fundamental phase field model for describing phase separation phenomena. Due to the presence of logarithmic singularities at $u=\pm 1$, the solution $u$ is constrained within the interval $(-1,1)$. While convex splitting schemes are commonly employed to preserve this bound and guarantee unconditional unique solvability, their practical implementation requires solving nonlinear systems containing singular logarithmic terms at ea…

Another day,
another 8.5h video calls,
another very short lunch break.
Another #cycling #workout combined with doing little errands for tomorrow's lunch.

This #photo is pretty soon after the first photo that I posted. I was on the way up and turned around to see the nice little meadow that I just crossed.
The #trail winding through the meadow with the trees around and the
