This is the base stack so the BSP stuff for my current board (i.e. the FPGA accelerator integration and FPGA Ethernet-over-QSPI MAC are not included) but this is probably most of the attack surface.

what is the typical design process for multiple token buckets?
e.g. if you have a bunch of go routines that:
listen to new domain registrations ->
check for IP token bucket (or rough /30 bucket?) -> if rate limited, stack in list of things to do in that prefix?? send to disk?
check for ASN token bucket - if cidr range is unknown, send to ASN querying and sleep(?)
ASN querying go routine -> rate limited to a request every 8 hours (100/month), or every 2-ish hours (500/month) - cached once known
when ASN becomes unblocked -> /now/ you can query the domain
(this also applies to queue design in general, when the thing you're queuing for might take a long while to dequeue in breadth first search, or if you have multiple rate limits to respect)
e.g., if I have it run an insert into "asn_lookups_resume_domains" for the ASN job to lookup, then resume/retry the domain jobs
or if it's completely blocking
or if it's just n-workers such that probably some prefixes are unblocked

Full-Duplex Beyond Self-Interference: The Unlimited Sensing Way
The success of full-stack full-duplex communication systems depends on how effectively one can achieve digital self-interference cancellation (SIC). Towards this end, in this paper, we consider unlimited sensing framework (USF) enabled full-duplex system. We show that by injecting folding non-linearities in the sensing pipeline, one can not only suppress self-interference but also recover the signal of interest (SoI). This approach leads to novel design of the receiver architecture that is comp…

Mayhem: Targeted Corruption of Register and Stack Variables
In the past decade, many vulnerabilities were discovered in microarchitectures which yielded attack vectors and motivated the study of countermeasures. Further, architectural and physical imperfections in DRAMs led to the discovery of Rowhammer attacks which give an adversary power to introduce bit flips in a victim's memory space. Numerous studies analyzed Rowhammer and proposed techniques to prevent it altogether or to mitigate its effects. In this work, we push the boundary and show how Ro…

The stack number of a directed acyclic graph $G$ is the minimum $k$ for which there is a topological ordering of $G$ and a $k$-coloring of the edges such that no two edges of the same color cross, i.e., have alternating endpoints along the topological ordering. We prove that the stack number of directed acyclic outerplanar graphs is bounded by a constant, which gives a positive answer to a conjecture by Heath, Pemmaraju and Trenk [SIAM J. Computing, 1999].

Non-semisimple Crane-Yetter theory varying over the character stack
Patrick Kinnear
https://arxiv.org/abs/2404.19667 https://arxiv.org/pdf/2404.19667
arXiv:2404.19667v1 Announce Type: new
Abstract: We construct a relative version of the Crane-Yetter topological quantum field theory in four dimensions, from non-semisimple data. Our theory is defined relative to the classical $G$-gauge theory in five dimensions -- this latter theory assigns to each manifold $M$ the appropriate linearization of the moduli stack of $G$-local systems, called the character stack. Our main result is to establish a relative invertibility property for our construction. This invertibility echoes -- recovers and greatly generalizes -- the key invertibility property of the original Crane-Yetter theory which allowed it to capture the framing anomaly of the celebrated Witten-Reshetikhin-Turaev theory. In particular our invertibilty statement at the level of surfaces implies a categorical, stacky version of the unicity theorem for skein algebras; at the level of 3-manifolds it equips the character stack with a canonical line bundle. Regarded as a topological symmetry defect of classical gauge theory, our work establishes invertibility of this defect by a gauging procedure.

This is incredibly tone-deaf of StackExchange. They're a community-driven project, and the community has been very clear that they are skeptical of AI and AI-driven business.
However, all SE data is also CC-BY, same as Wikipedia, which means OpenAI is pretty well-justified in just crawling the SE data. I'm not sure what this agreement buys either party.

Representability of Elliptic Moduli Problems in Derived $C^{\infty}$-Geometry
We study moduli spaces of solutions of nonlinear Partial Differential Equations on manifolds in the framework of derived $C^{\infty}$-geometry. For an arbitrary smooth stack $S$, we define $S$-families of nonlinear PDEs acting between $S$-families of submersions over an $S$-family of manifolds and show that in case the family of PDEs is elliptic and the base family of manifolds is proper over $S$, then the moduli stack of solutions is relatively representable by quasi-smooth derived $C^{\infty}…

Should my Blockchain Learn to Drive? A Study of Hyperledger Fabric
Similar to other transaction processing frameworks, blockchain systems need to be dynamically reconfigured to adapt to varying workloads and changes in network conditions. However, achieving optimal reconfiguration is particularly challenging due to the complexity of the blockchain stack, which has diverse configurable parameters. This paper explores the concept of self-driving blockchains, which have the potential to predict workload changes and reconfigure themselves for optimal performance w…

"build exciting things with boring technology"

"By 1973, the first volume of the defining work of our craft, “The Art of Computer Programming” had been available in bookstores since 1968, and its first chapter literally consisted of a 100-something page long introduction to various mathematical concepts. Induction, logarithms, series, matrices, elementary number theory, permutations and factorials, Fibonacci numbers, are some of the subjects exposed in those beautifully typeset pages."

In Praise Of Mathematics
How much math knowledge does a programmer need to know to fulfill their job? How deep should the mathematical knowledge of full-stack engineers, computer security experts, or large language model engineers be? The spectrum of possible answers to these questions is too large to be useful. Perhaps the eternal answer "it depends" is enough?

Nonabelian Hodge theory for stacks and a stacky P=W conjecture
We introduce a version of the P=W conjecture relating the Borel-Moore homology of the stack of representations of the fundamental group of a genus g Riemann surface with the Borel-Moore homology of the stack of degree zero semistable Higgs bundles on a smooth projective complex curve of genus $g$. In order to state the conjecture we propose a construction of a canonical isomorphism between these Borel-Moore homology groups. We relate the stacky P=W conjecture with the original P=W conjecture co…
