Quick overview of the insights gathered from interviewing 10 users about how they manage preferences and configurations in Thunderbird desktop.

tail -f for signals. Every signal any process on the box raises — who sent it, who it hit, which signal, how it was raised (kill(2), the kernel, a POSIX timer), whether the target caught it and how...

My book club is reading Abundance by Ezra Klein and Derek Thompson this month. The core idea fits on a napkin, so before the meeting I de...

Application-layer firewall decisions at XDP, before a socket buffer exists. We built a firewall that decides on HTTP/2 headers in the kernel with eBPF and lets you write the policy as a JavaScript app. The decision lands in the nanoseconds, changing a rule takes no rebuild or restart, and it's already running in front of real enterprise traffic. Here's how it works.

This report examines how modern, open-source assessment methods could be used to produce fair, transparent, and affordable countywide reassessments.

Frustrated by my arXiv submission being moved into the "on hold" queue, I did what any reasonable person would do in this situation: an analysis of arXiv submission delay times since 2015.

Postgres is great, but there are some very common problems that people have that can pretty easily lead to outages with Postgres. These aren’t just theoretical issues. From talking to a lot of startups, these are the things that actually cause outages in production, especially on teams that don’t have a dedicated database person. These […]

IPv6-only networks often still depend on IPv4 subnets and ARP. This article introduces an IETF proposal to eliminate both, allowing IPv4 to operate as a service over IPv6-only infrastructure without translation or tunnelling.

Pathfinding around a set of circular obstacles

We have developed and shared a low-precision RL recipe preserving higher-precision training dynamics. In this recipe, we needed to address instability from the forward pass due to policy quantization errors, from the backward pass due to gradient mismatches, and at the intersection of both due to a small set of particularly sensitive weights. We explain how we addressed each and validated the final recipe.

When engineers think about protective materials, like those used in packaging and support, they usually think about strength, stiffness and durability. But what if those same materials could also sense their external environment? That question emerged unexpectedly for Ling Li, Associate Professor in Materials Science and Engineering, when his lab and colleagues were investigating how […]

Frontier labs are locking the strongest models behind metered APIs and lobbying that open weights are a national-security problem. Licenses won't stop regulatory capture. The defense has to be architectural.

New multilingual voices for Grok Voice, plus improved naturalness for the original five.

The problem of storing secure information on a network is studied. A formal framework for distributed secret storage is introduced, and possible applications in technological and social systems are discussed. The problem is formulated as the optimization of a robustness functional in which two competing requirements are balanced: survivability under network-degrading processes and resistance to adversarial compromise. An exact representation of survivability is derived in terms of minimal information-carrying subgraphs (MICS), which provide a reduced description of the reconstruction events relevant to the stored information. This representation is then used to construct semi-local optimization methods whose dynamics do not require global knowledge of the network structure. Finally, it is shown that, in a limiting case, the robustness functional can be mapped naturally to an effective spin Hamiltonian.

Hey folks, Fireside this week! I’ve been a bit behind because we had some family travel followed by an issue with a water leak in the basement which has pushed me out of my normal home office…
