Tech ain't that deep - and that's a problem | deadSimpleTech
With that in mind, it became fairly clear to me that the tech industry these days has a depth problem: as much as tech is becoming quite a bit more complex, it's also becoming shallower. Learning new things in tech these days, as often as not, simply doesn't give me the same feeling of satisfaction or achievement as learning or writing C back in the first years of my career did. Being effective in tech these days feels as though it's less about understanding than it is about memorising a big li…

Okay, resume rewritten and we're now on hour 3 of the red beans and sausage part of red beans and rice that I'm having for supper. Feeling pretty productive, gonna send out the first batch o' resumes once I read over the new resume. However, one slight problem: the entire house smells delicious...I am so very, very hungry.

Not entirely sure what my brain was up to, but it prompted Nano Banana to generate an “Overly Concerned Drafthorse,” and well, that’s that.

CRAN Task View: Optimization and Mathematical Programming
This CRAN Task View contains a list of packages that offer facilities for solving optimization problems. Although every regression model in statistics solves an optimization problem, they are not part of this view. If you are looking for regression methods, the following views will also contain useful starting points: MachineLearning, Econometrics, Robust Packages are categorized according to the following sections. See also the “Related Links” and “Other Resources” sections at the end.

National parks are deteriorating. There’s a fix Congress isn’t making.
The national park system faces a maintenance backlog of $24 billion in crumbling roads, aging water systems, washed-out trails and dilapidated visitor facilities.
That is more than seven times the National Park Service’s annual budget.

Last month, committees in both the House and Senate advanced bipartisan bills to dedicate roughly $1.3 billion annually for park maintenance over the next five years. …

America’s national parks are falling apart. Congress can fix them.
Legislators should fund routine maintenance to prevent bigger problems.

Runway started by helping filmmakers. Now it wants to beat Google at AI. | TechCrunch
AI video generation startup Runway is betting that video generation is the path to world models. And that being an AI outsider is an advantage, not a liability.

Abstract: We present a comprehensive framework for gravity-driven, surfactant-laden thin films flowing over slippery substrates, elucidating how wall slip modifies the coupled hydrodynamics and interfacial transport. A long-wave model is formulated with a conservative bulk-surface mass balance and a Navier slip condition. The Orr-Sommerfeld eigenvalue problem governs the linear regime, while a weighted-residual model captures the nonlinear evolution over a range of equilibrium surfactant coverages, Marangoni strengths, and adsorption kinetics. The analysis predicts a non-monotonic variation of the critical Reynolds number with equilibrium coverage, exhibiting a maximum at intermediate $\Gamma_e$, and a slip-induced transition from single- to double-hump solitary structures with increasing Marangoni number, accompanied by attenuated capillary ripples. Under fast adsorption kinetics, the surface field homogenizes, preserving the mean film shape and flux while flattening both the surface concentration $\Gamma$ and the bulk inventory $\chi h\phi$. A spurious interfacial mass growth reported by Pascal et al.(PRF, 2019) and D'Alessio et al.(JFM, 2020) is resolved through a revised surface balance ensuring strict conservation. Wall slip thus emerges as a key control parameter, reducing viscous resistance and mitigating Marangoni back-stress. The slip parameter $\beta$ is a useful control knob for surfactant-laden films. Slip prevents fragile multi-hump bound states, promoting a single broad crest or an almost flat, uniform sheet by carefully bonding $\beta$ to wave selection, ripple damping, and the bulk-surface surfactant balance.

An invisible forever chemical rain is falling across the planet #environment

An invisible forever chemical rain is falling across the planet
A surprising study suggests that chemicals introduced to protect the ozone layer may have unintentionally created a growing global pollution problem. Researchers found that refrigerants and certain anesthetic gases have generated more than 335,000 tonnes of trifluoroacetic acid (TFA), a highly persistent "forever chemical," that has been deposited across Earth's surface since 2000. The pollutant is now showing up everywhere from rainwater to remote Arctic ice, and scientists expect levels to ke…
