Defense Secretary Pete Hegseth was quickly met with sharp questions and criticism Tuesday
by lawmakers who pressed him about his early moves to deploy troops to Los Angeles,
fire key military leaders
and purge diversity programs.
They expressed bipartisan frustration that Congress has not yet gotten a full defense budget from the Trump administration.
“Your tenure as secretary has been marked by endless chaos,”
Rep. Rosa DeLauro, D-Conn., told Hegseth.

Hegseth faces Democrats in Congress for first time since Signal leaks
Defense Secretary Pete Hegseth has been met with sharp questions and criticism by lawmakers who demanded details on his moves to deploy troops to Los Angeles. Lawmakers also expressed bipartisan frustration Tuesday that Congress doesn't yet have a full defense budget from the Trump administration. The hearing before the House Appropriations defense subcommittee was the first time lawmakers have been able to challenge Trump’s defense chief directly. After persistent questioning about the cost …

I’ve been trying to “vibe code” a couple of things over the last few days, but I had to fall back on using my brain (like a sucker!).
I should keep some of this coding knowledge knocking around a little longer before cat videos and memes fill those parts of my brain.
My vibe must be off :P

Longer Lists Yield Better Matchings
Many centralized mechanisms for two-sided matching markets that enjoy strong theoretical properties assume that the planner solicits full information on the preferences of each participating agent. In particular, they expect that participants compile and communicate their complete preference lists over agents from the other side of the market. However, real-world markets are often very large and agents cannot always be expected to even produce a ranking of all options on the other side. It is t…

' “How do we afford public ownership?” You squeeze the water companies hard. If they’re no longer making a profit, their so-called “market value” (based on ripping you off) will fall. As they collapse, like Thames Water, they can be taken into public ownership for a song, and their debt can be refinanced more cheaply in the public sector – with the savings going to reduce bills, invest in stopping sewage, or both."

I maintain a heterogeneous MSP environment for backup which consists of a collection of sh scripts (they mostly run on FreeBSD) with (c) notes dating back to 2004, with 5 authors, 4 of whom are no longer my cow-orkers. As the unfortunate 5th, I am still doing tweaks to catch edge & corner cases >20y after the 1st author had the idea that rsync, shell, mt, & standard POSIX tools could be assembled into a decent free backup world.
Use Python. Or Go. Or even Perl.

This is an especially good time for you vacationers who plan to fly, because
the Reagan administration, as part of the same policy under which it
recently sold Yellowstone National Park to Wayne Newton, has "deregulated"
the airline industry. What this means for you, the consumer, is that the
airlines are no longer required to follow any rules whatsoever. They can
show snuff movies. They can charge for oxygen. They can hire pilots right
out of Vend…

Evaluating the Impact of Privacy-Preserving Federated Learning on CAN Intrusion Detection
The challenges derived from the data-intensive nature of machine learning in conjunction with technologies that enable novel paradigms such as V2X and the potential offered by 5G communication, allow and justify the deployment of Federated Learning (FL) solutions in the vehicular intrusion detection domain. In this paper, we investigate the effects of integrating FL strategies into the machine learning-based intrusion detection process for on-board vehicular networks. Accordingly, we propose a …

Fluid Simulation on Vortex Particle Flow Maps
We propose the Vortex Particle Flow Map (VPFM) method to simulate incompressible flow with complex vortical evolution in the presence of dynamic solid boundaries. The core insight of our approach is that vorticity is an ideal quantity for evolution on particle flow maps, enabling significantly longer flow map distances compared to other fluid quantities like velocity or impulse. To achieve this goal, we developed a hybrid Eulerian-Lagrangian representation that evolves vorticity and flow map qu…

Characterising the Standardisation Properties of Type Ia Supernovae in the z band with Hierarchical Bayesian Modelling
Type Ia supernovae (SNe Ia) are standardisable candles: their peak magnitudes can be corrected for correlations between light curve properties and their luminosities to precisely estimate distances. Understanding SN Ia standardisation across wavelength improves methods for correcting SN Ia magnitudes. Using 150 SNe Ia from the Foundation Supernova Survey and Young Supernova Experiment, we present the first study focusing on SN Ia standardisation properties in the z band. Straddling the optical …
