Good Morning #Canada
In August 1998, the Supreme Court of Canada ruled that Quebec could not legally secede from Canada unilaterally. The court's decision affirmed that any secession would require a constitutional amendment negotiated with the federal government and other provinces. This ruling stemmed from a reference case initiated by the federal government following a close referendum on Quebec sovereignty in 1995. Although Quebec was represented at the Supreme Supreme Court hearing, they did not participate in presenting arguments. They essentially ignored the ruling and planned a future referendum, which never happened.
This ruling established an important precedent that Alberta separatists should pay attention to. But details such as this ruling, aboriginal rights, or common sense seem to escape their attention spans.

Inside the Long Friendship Between Trump and Epstein
For nearly 15 years, the two men socialized together in Manhattan and Palm Beach, Fla., before a falling out that preceded Mr. Epstein’s first arrest.

I cannot stress enough the stupidity of e.g. "ACAB" and "ABOLISH THE POLICE"
Get out of your feelings and get into your strategy -- it is undeniably true that there is a SEVERE need for police reform
But, tell me, who escorted ICE away from Dodger Stadium?

Fear of flying therapy is about reframing the flight experience;
if my mind’s eye squints,
I can almost interpret my sweating palms and pounding heartbeat as a kind of buzz.
But this requires repeated, strenuous effort,
and the result is a mental exhaustion that makes the worst-case scenario appealing:
succumbing to my fears and never flying again.
I imagine this as analogous to what many Americans, aerophobic or not, are feeling.
It’s simply easier…

For those trying to overcome their fears of flying, it’s been . . . a challenging time to say the least.

Optimal alignment of Lorentz orientation and generalization to matrix Lie groups

Optimal alignment of Lorentz orientation and generalization to matrix Lie groups
There exist elegant methods of aligning point clouds in $\mathbb R^3$. Unfortunately, these methods rely on the positive definite property of the Euclidean metric, and do not easily extend to the indefinite Minkowski metric. In this paper, we propose two solutions to the following problem: given inertial reference frames $A$ and $B$, and given (possibly noisy) measurements of a set of 4-vectors $\{v_i\}$ made in those reference frames with components $\{v_{A,i}\}$ and $\{v_{B,i}\}$, find the op…

hey quick question
what drugs were the RMII people on
multiplexing a fully asynchronous signal (CRS) with a fully synchronous signal (DV) to get this weird... half-asynchronous-half-synchronous thing where *some* rising edges are referenced to REF_CLK and some are not, but all falling edges are
what is wrong with them? and more importantly how the fuck are you supposed to use it in a MAC??

High-gain model-following control for trajectory tracking
We consider trajectory tracking for minimum-phase nonlinear systems in Byrnes-Isidori form using the model-following control (MFC) architecture. The tracking problem is motivated by a hierarchical control concept where a higher-level instance provides the reference trajectory at run-time. We present a computational efficient implementation of the feedback linearisation MFC design, and apply high-gain feedback in the process control loop (PCL) to achieve practical tracking in presence of Lipschi…

Vision-driven River Following of UAV via Safe Reinforcement Learning using Semantic Dynamics Model
Vision-driven autonomous river following by Unmanned Aerial Vehicles is critical for applications such as rescue, surveillance, and environmental monitoring, particularly in dense riverine environments where GPS signals are unreliable. We formalize river following as a coverage control problem in which the reward function is submodular, yielding diminishing returns as more unique river segments are visited, thereby framing the task as a Submodular Markov Decision Process. First, we introduce Ma…
