- Analytics Caddy Microservice — Privacy-friendly analytics microservice using server logs
-
For small organisations and individuals who wish to respect their visitors' privacy while needing to obtain analytics, there are limited options. The most elegant option (and the most privacy-respecting one) is to provide real-time analytics by ingesting the web server logs. This doesn't involve/require doing anything client-side (no scripting, no invisible pixels, etc): all the information needed can be derived from these log files without resorting to tricks. The form factor of a drop-in microservice allows for easy integration into other tools (which offers a significant improvement in terms of usability), and makes it portable. The end result will provide a neat solution for small actors to make self-hosting of their website 'batteries included'.

- Bubble-up — Declaritive schema migrations for sqlite databases
-
SQLite is widely regarded as the most-used database engine, with sqlite.org even suggesting that it surpasses all other engines combined. One of its main advantages is its simplicity—operating on a single file. However, while getting started with SQLite is straightforward, modifying the database schema can be more complex due to its limited support for ALTER commands compared to other databases.
Bubble-up is a command-line tool designed to ease this challenge. It enables seamless schema migrations for SQLite databases by comparing your desired schema (written in a simple SQL file with standard DDL statements) to the current database structure, and performing the necessary changes.

- Test Procedures for MOSFET Open Source SPICE Model Validation — Test Procedures for MOSFET SPICE Model Validation
-
The emergence of open PDK initiatives reduce barriers to entry for integrated circuit (IC) design and manufacturing, serves thelong term goal of promoting academic/industrial collaboration, and stimulate innovation in the field of semiconductor IC design. Open PDKs have the potential to "standardize" PDKs (process design kit), and move away from proprietary/licensed EDA vendor formats. This is needed to democratize open source IC design flow and manufacturing. Open PDKs provide open access to IC design resources.
The compact/SPICE models of semiconductor devices are the core of open PDK efforts. SPICE executes implemented Verilog-A compact models. A model of a semiconductor device (passive elements and active, eg: diodes, mosfets, bjts) is primarily a "compact device model". Validation benchmarks are not yet available in the public domain. This project represents the very first attempt to implement these tests for the compact model available in open PDKs. It aims to establish such tests for the compact models in open PDKs, which are intended to be generic enough for model quality assurance testing with FOSS circuit simulators such as GnuCAP, ngspice, xyce, Qucs, among others.

- Re-isearch Schmate — Extending re-Isearch with a flat vector datatype for embeddings
-
Schmate is the development name for the evolving next iteration of re-Isearch adding vector datatypes for embeddings and applications like retrieval augmented generation (RAG). Schmate (pronounced "SHMAH-teh") is Yiddish for rag (שמאטע).
In contrast to typical vector stores the proposed re-Isearch+ shall offer a full passage information retrieval system (index and retrieval) using a combination of dense and sparse vectors as well as structure. It is dense passage retrieval (DPR) and a whole lot more. It addresses the stumbling blocks of chunking, has a tight integration of ingest, tokenisation, a number of alternative vector stores and similarity algorithms and, above all, uses a novel combination of understanding document structure (implicit and explicit) to provide a better contextual passage retrieval to solve the problem of misaligned context. This builds on the observation that meaning is also communicated through structure so needs to be viewed in the context of structure. Since structure like the words are meant by the sender (writer) to be received and understood (reader) our approach is to exploit the original author's organization of content to determine appropriate passages rather than relying solely on the chunks.

- Smart lookup & inference for Semantic Data — Knowledge mapping within a postgresql database
-
Semantic knowledge representations have not evolved since the Semantic Web was proposed during the 1990s. Modern graph databases offer new possibilities for knowledge representation, but the methods are poorly developed and require the use of specialized query languages and clumsy outdated formats. This project aims to make semantic maps easy for general use, using standard SQL databases and modern lightweight data formats. A user workflow starts from a simple note-taking language, then ingesting into a database using a graph model based on the causal semantic spacetime model, to the use of a simple web application for supporting graph searches and data presentation. The aim is to make a generally useful library for incorporating into other applications, or running as a standalone notebook service.

- Sniffnet — User-friendly network monitoring application
-
Sniffnet is a cross-platform, Rust-based, fully open-source network monitoring application to help everyone keep an eye on their Internet traffic. Sniffnet is a technical tool, but at the same time it strongly focuses on the overall user experience: most of the network analyzers out there are cumbersome to use, while one of Sniffnet's cornerstones is to be usable with ease by virtually anyone. In an era dominated by network traffic encryption, Sniffnet doesn’t follow the standard monitoring approach that included reporting full packets’ payloads, but rather it provides flow-level details such as the country, the organization, the domain name, the upper-layer service, and other parameters that enable a more immediate understanding about the nature of the network traffic.

- Verilog-A distiller — Automated porting of models from C to Verilog-A
-
Analog circuit simulators require compact device models in order to be able to simulate circuits. The de-facto standard language for compact device model dissemination is Verilog-A. Many legacy models exist that are coded for the SPICE3 circuit simulator in the C programming language. Manual conversion from C to Verilog-A is resource-intensive, time-consuming, and error-prone. This reduces the accessibility of legacy models and limits innovation. The Verilog-A Distiller project aims to automate conversion of SPICE3 device models from C to Verilog-A. By automating this conversion, we aim to streamline model implementation, reduce development time, and enhance compatibility across different simulators. Verilog-A Distiller is a converter written in Python that utilizes the pycparser library for reading the C code of SPICE3 models. The parsed models are pruned of unnecessary SPICE3-specific parts, upon which Verilog-A code is emitted. Projects like Ngspice put a lot of effort into cleaning up and improving legacy SPICE3 models. Verilog-A Distiller makes these models available across a wide range of simulators that support Verilog-A.
