Until now, my HF antennas have mostly been off the shelf. I’ve gone out with an AlexLoop (hmm, alexloop.com seems to be down. I don’t know if that’s permanen...

Asked whether code is malicious, a MoE model recruits a morality-associated expert path.

How we capture real production database traffic at Airbnb and replay it offline to load-test, plan capacity, and de-risk upgrades.

OpenAI’s incentives are to control your context. How should we resist?

Meta’s public time service now speaks NTS (Network Time Security, RFC 8915) at nts.meta.com. Packets are authenticated, so a device can verify the time came from us and was not modified on the way.…

Planner-validated index advice, built for real and timed on the Join Order Benchmark.

tapo now logs in over the TPAP protocol, so the Third-Party Compatibility switch in the Tapo app can stay off. Also new: H200 and H500 camera hubs with recording downloads, and plug schedules and timers.

If you just need bash, why do you need codemode?

Server chips traditionally offered less single threaded performance than contemporary client parts.

“Write tests… first ? That sounds backwards.” I know exactly what you mean, but stay with me. This is going somewhere… backwards, and in high heels!

DataFrames for the new era

For teams that own the backend, I treat test-data setup as the primary design problem. It should shape the choice of testing tools.

This is part 2 of a series about Postgres logical replication use-cases, and about how the feature set has evolved over the past ten years and ten releases, one …

For years everybody agreed that tests make software better, and almost nobody wrote them. In the first ten years or so of my career I probably didn’t write a single test. I always felt a bit guilty…

IFCO tracks millions of crates. See how its data team scaled, debugged, and operates the dbt-on-Databricks project behind those KPIs.

How to implement basic emergency preparedness to get your loved ones out of bad situations

We give the first polynomial improvements over the textbook algorithms for $3$SUM and All-Pairs Shortest Paths (APSP): we show how to deterministically solve $3$SUM on $n$ integers of polynomial size in $O(n^{1.9992})$ time and APSP on directed $n$-vertex graphs with polynomially bounded integer wei

Consequences of integral promotion, UB on unscoped enums, and why boolean conversion is surprising.

We clustered an ASUS ET900N G3 and an HP ZGX Fury over two 400G DACs and served GLM-5.2, GLM-5.3, and MiniMax-M3 across both GB300 Stations.

Around a year ago (it might have been more, my memory can be spotty) I experienced the raycaster ...Continue reading →

AI-driven hazard tools are increasingly proposed for resident-facing risk communication. However, residents are often asked for feedback only after decisions about data use, privacy, and explanation have been made. This study takes an earlier approach by examining residents' values, concerns, and pr

In cognitive psychology, the sense of agency refers to the feeling of controlling an external event through one's own actions. This paper asks how people experience agency when they give an instruction to a computer, which then acts on their behalf. Research in human-human interaction has found that

AI sycophancy, the tendency of AI systems to excessively agree with, flatter, or validate users, is an emerging concern in human-AI interaction. It is especially consequential in problem-sharing contexts, where users may seek both information and emotional validation. This paper conceptualizes AI sy

In the year $1977,$ while developing the theory of modules arising in the context of Serre's problem on projective modules in the paper ``On Stably Free Modules" (see \cite{AS}), A. A. Suslin constructed matrices inductively using unimodular rows. Our aim is to connect these matrices to the current

The magnitude of the generalized Euclidean cross product is a Gram volume whose degree under common scaling is fixed by the integer dimension of the spanning frame. We formulate a generalized Fractal Cross Product (FCP) as a nonlinear radial deformation with a prescribed positive degree $D$, which m

I've been part of open source for most of my life. This year, the projects I love started closing their doors to outside contributors, and I don't blame them one bit, but it makes me sad. A personal look at how AI is changing open source as I've known it.

Continuous colormaps are widely used to visualize scalar fields, and their quality is typically evaluated using measures such as discriminative power and uniformity. Existing measures primarily characterize the intrinsic perceptual properties of the colormap itself, largely independent of the underl

Recent program evolution systems use large language models (LLMs) to generate and iteratively improve populations of programs, producing striking advances in mathematics, algorithm design, and scientific computing. Yet these systems largely operate as fully automated black boxes. As populations grow

Objective. Ear-worn biopotential devices are being designed around a coupling that has not been computed: how strongly each speech articulator reaches electrodes on the jaw and around the ear. We compute it, and test the answer against the three things that could produce it spuriously - source orien

Let $q$ be a power of an odd prime $p$. We prove the MDS conjecture over $\mathbb F_q$ in dimension $k$ whenever \[ 2\leqslant k\leqslant B(p,q) \quad\text{or}\quad q+2-B(p,q)\leqslant k\leqslant q, \] where $B(p,q)=\left\lfloor\frac{(p-2)q+6p-10}{2p-3}\right\rfloor$. For fixed $p$, this gives a ran

Distributed mixture-of-experts (MoE) inference is a promising architecture for deploying large language models (LLMs) at wireless edge networks because sparse experts can be placed across coordinated base stations (BSs), while the anchor node and user equipment (UE) can offload LLM inference tasks t

Small DSLs turn LLM-written code into reusable decisions, with image inclusion in a context compiler as the worked example.

The secret ballot is one of the load-bearing walls of democracy. In Georgia, as in most states, this allows you to know whether your neighbor voted, but never who they voted for. Yet, in multiple states including Georgia, that guarantee is actively at risk.

The `notify_buffers` GUC tunes a 128kB cache for PostgreSQL's LISTEN/NOTIFY queue—and almost never matters.
