The log viewer in ngscopeclient now includes a graphical interface to logtools filters, allowing you to filter by severity and turn high-verbosity tracing on/off for specific classes and functions.

Combined Public Service Announcement and Today I Learned: if you have `CLICOLOR=1` on macOS, if you do an `ls` of a directory which is inside iCloud Drive, evicted files (i.e., those that cannot be immediately used, but need to be downloaded first from iCloud) show with a grey background… see below:
First, both files are in iCloud, but not locally available. They have a dotted cloud icons in the iCloud Status field of the Finder window, and a greyed background in the output of the `ls` …

Towards EXPTIME One Way Functions: Bloom Filters, Succinct Graphs, Cliques, & Self Masking
Consider graphs of n nodes, and use a Bloom filter of length 2 log3 n bits. An edge between nodes i and j, with i < j, turns on a certain bit of the Bloom filter according to a hash function on i and j. Pick a set of log n nodes and turn on all the bits of the Bloom filter required for these log n nodes to form a clique. As a result, the Bloom filter implies the existence of certain other edges, those edges (x, y), with x < y, such that all the bits selected by applying the hash functions to x …

SkimROOT: Accelerating LHC Data Filtering with Near-Storage Processing
Data analysis in high-energy physics (HEP) begins with data reduction, where vast datasets are filtered to extract relevant events. At the Large Hadron Collider (LHC), this process is bottlenecked by slow data transfers between storage and compute nodes. To address this, we introduce SkimROOT, a near-data filtering system leveraging Data Processing Units (DPUs) to accelerate LHC data analysis. By performing filtering directly on storage servers and returning only the relevant data, SkimROOT min…

Good stuff for Mac Users. I’ve used it forever. Really handy, and it works well.

Co-designed reflective and leaky-waveguide low-pass filter for superconducting circuits
A stepped-impedance low-pass filter with integrated hollow waveguide absorbers is presented. The filter combines low insertion loss in the passband with strong attenuation at high frequencies, making it well suited for superconducting quantum computing applications, where qubits are sensitive to both near-band and far out-of-band radiation. The structure is implemented in a rectangular coaxial geometry, with inductive sections coupled to circular hollow waveguides oriented orthogonally to the t…

Equivariant Symmetries for Inertial Navigation Systems
This paper investigates the problem of inertial navigation system (INS) filter design through the lens of symmetry. The extended Kalman filter (EKF) and its variants have been the staple of INS filtering for 50 years. However, recent advances in inertial navigation systems have exploited matrix Lie group structure to design stochastic filters and state observers that have been shown to display superior performance compared to classical solutions. In this work, we explore various symmetries of i…
