Revisiting $O(n \log \log n)$ chaining for anchored edit distance

arXiv:2606.03929v1 Announce Type: new Abstract: Colinear chaining is a classical heuristic for sequence alignment: it enables scalable genome comparison and is a main component of many state-of-the-art read mappers based on seed-chain-extend. The earliest $O(n \log \log n)$ time algorithms by Eppstein et al. (J. ACM, 1992) chained $n$ fragments between two sequences $T$ and $Q$ while minimizing a gap cost based on the diagonal distance $\Delta_{\text{diag}}$ between consecutive fragments.

Gaussian Point Splatting

Gaussian Point Splatting Joris Rijsdijk, Christoph Peters, Michael Weinnman, Ricardo Marroquim. 2026–07 in ACM Transactions on Graphics (Proc. Official version Abstract We propose Gaussian point splatting, a stochastic method to render Gaussian splats that scales extremely well to scenes with many Gaussians.

Parallel Reconstruction of Lawful TLS Wiretapping

Parallel Reconstruction of Lawful TLS Wiretapping Transport Layer Security (TLS) is the protocol involved in getting the lock icon to appear in your browser next to the URL. Under the hood it uses a bunch of really cool numbers for encryption. Some numbers are considered private and need securing; some are considered public and are fine for sharing.

The Uncertain Future of the Smithsonian’s Smallest Museum

In 1969, the Anacostia Neighborhood Museum, in Washington, D.C., debuted a new exhibit: “The Rat: Man’s Invited Affliction.” The display—complete with live rats—was different from what people were used to seeing from the venerable Smithsonian Institution. At the time, the main event at the Museum of History and Technology (now the National Museum of American History) was an exhibit that focused on the fanfare of presidential campaigns and conventions.

A Post-Quantum Future for Let's Encrypt

Let’s Encrypt is committed to a post-quantum-safe Web PKI. The path we’re planning to take is Merkle Tree Certificates (“MTCs”), a new approach that adds post-quantum authentication to the web without sacrificing the speed and reliability that have made TLS universal. This post is about these plans and why we believe MTCs are worth pursuing as a key to a post-quantum future.

PriSrv: Privacy-Enhanced and Highly Usable Service Discovery in Wireless Communications

arXiv:2606.05821v1 Announce Type: new Abstract: Service discovery is essential in wireless communications. However, existing protocols provide limited privacy protection, leaking sensitive device information and opening routes to network attacks. This paper proposes a private service discovery protocol, called PriSrv, which enables both service providers and clients to specify fine-grained authentication policies before establishing connections.

Quantum Time Lower Bounds by Permutation Invariance

arXiv:2606.05099v1 Announce Type: cross Abstract: Tight bounds on quantum sample complexity and quantum query complexity have been known for various computational problems in the literature, whereas tight bounds on quantum time complexity (i.e., the size of quantum circuits) remain unresolved. In this paper, we provide a framework to establish lower bounds on the quantum time complexity for testing permutation-invariant properties of quantum states, via a reduction from quantum sample...

Self-hosted dev sandboxes with preview URLs (Docker, Go, no K8s)

The open-source engine for AI app-builder products. Give every user an isolated cloud dev environment, a built-in coding agent, and a live preview URL — self-hosted, on one machine, in one command. Think of the apps where you type "build me a todo app" and seconds later a working website appears at its own link — like Lovable, Bolt, v0, or Replit. sandboxed is the open-source backend that makes that possible, running on your own server.
