Rewriting the Ruby parser
At Shopify, we have spent the last year writing a new Ruby parser, which we’ve called YARP (Yet Another Ruby Parser). As of the date of this post, YARP can parse a semantically equivalent syntax tree to Ruby 3.3 on every Ruby file in Shopify’s main codebase, GitHub’s main codebase, CRuby, and the 100 most popular gems downloaded from rubygems.org. We recently got approval to merge this work into CRuby, and are very excited to share our work with the community. This post will take you thro…

Krugman continues:
❝While there is a cadre of Trumpist true believers who will obey the Leader under any circumstances, most of those doing the dirty work of undermining democracy and the rule of law are cowards and opportunists. They’re willing to participate in the destruction of America as we know it because they believe that many others will do the same. As a result, they believe that they are unlikely to face any personal consequences for their actions and may even be rewarded for their lawbreaking.
And what of those who oppose Trumpism? While there are heroes willing to take a stand against tyranny whatever the personal cost, most anti-Trumpists are reluctant to stick their necks out unless they believe that they are part of a widespread resistance that will grant them some measure of safety in numbers.
In other words, the victory or defeat of competitive authoritarianism will depend to a large extent on which side ordinary people believe will win. If Trump looks unstoppable, resistance will wither away and democracy will be lost. On the other hand, if he appears weak and stymied, resistance will grow and — just maybe — American democracy will survive.❞

On the Control of Solutions of a Viscoelastic Plate Problem with a Frictional Damping Term
In this article, we study the stability of solutions to a nonlinear viscoelastic plate problem with frictional damping of a memory on a part of the boundary, and a logarithmic source in a bounded domain $Ω\subset \mathbb{R}^2.$ In this problem the relaxation function $r$ satisfies $r^{\prime}\left( t\right)\leq -h\left( t\right) \mathcal{G}\left( r\left( t\right) \right)$ for all $t\geq 0$, where $h$ is a nonincreasing positive function. This work extends previous works with viscoelastic plate…

MastodonFedivers is a character on the EU server of Albion Online that I made specifically for this I guess, playing and talking about my adventures here...
Edit:
I also realized there is no guild in the entirety of Albion Online EU that got "fediverse" in it.
Also any guild with 'mastodon' in it is ALSO missing!
I got an idea for "variable tax" ie. one week it is 100%, another week it's 0%...could work?

Theoretical uncertainties for primordial black holes from cosmological phase transitions
Strongly supercooled first-order phase transitions have been proposed as a primordial black hole (PBH) production mechanism. While previous works rely on simplified models with limited thermodynamic precision, we stress that reliable theoretical PBH predictions require precise nucleation dynamics within realistic, classically conformal extensions of the Standard Model. By employing high-temperature dimensional reduction and computing the one-loop fluctuation determinants, we provide a state-of-…

Bandwidth enhanced current noise suppression with a SERF magnetometer
This work investigates the behavior of a spin-exchange relaxation-free (SERF) magnetometer integrated into the feedback branch of a closed-loop control circuit, designed to actively suppress noise from a current source. In this configuration, the magnetometer bandwidth is enhanced by almost two orders of magnitude as compared to the open-loop setup. Incorporating an injection transformer, the proposed system effectively reduces current noise to below 3 nA/sqrt(Hz) over a broad frequency bandwid…

Zigzag antiferromagnets in the SU(3) Hubbard model on the square lattice
SU(N) Hubbard models exhibit a rich variety of phases, which may be realized through quantum simulation with ultracold atomic gases in optical lattices. In this work we study the Mott insulating phases of the SU(3) Hubbard model at 1/3-filling using infinite projected entangled-pair states, optimized with both imaginary time evolution and variational optimization. In the limit of strong interactions we reproduce the antiferromagnetic 3-sublattice ordered state previously identified in the SU(3)…

Surfacing Pathological Behaviors in Language Models
We train reinforcement learning (RL) agents to craft realistic natural-language prompts that elicit specified behaviors in frontier open-weight models (Llama 3.1/4, Qwen 2.5, and DeepSeek-V3), using a proposed variational lower bound to guide the search.
