Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ask HN: Who is hiring? (May 2023)
Observatory of Geneva | Rust/Python Software Engineer | Geneva (Switzerland) | Hybrid Schedule | Full time (2.5 years)
The Observatory of Geneva (World renown in the field of exoplanetology, where Michel Mayor and Didier Queloz detected the first exoplanet, which got them a Nobel Prize in physics in 2019), in collaboration with the CEA (a French public government-funded research organization), will be seeking one talented junior software engineer to develop and improve two scientific codes which will predict the destiny of planetary systems (ESPEM & Posidonius, see https://github.com/marblestation/posidonius).
The successful candidate will:
- Collect the requirements (e.g., the code must run in multiple operating systems, provide pluggable solvers) that will inform future decisions about the design and implementation of a new ESPEM;
- Evaluate the use of more modern programming languages and design patterns (such as Rust and Python 3) for the new ESPEM;
- Design and implement a new version of ESPEM, reproducing the physics present in the current version of ESPEM but following the best coding practices;
- Design building blocks that will allow the implementation of new physics in a modular architecture for the new ESPEM;
- Implementation and integration of new physics in ESPEM and Posidonius;
- Write the corresponding documentation;
- Write unit tests to reach a coverage above 80% of the code;
- Identify optimizations that could help reduce the execution time, particularly certain functionalities that are more computing intense;
- Write visualization routines to easily explore the results.
Entry salary of 85,000 CHF with annual revisions + flexible schedule/environment (up to two days of allowed remote work) + friendly working culture with nice work-life balance + international travels (e.g. CEA headquarters in the Paris region, conferences).
Your contribution will be open source and it will have a world-wide impact in the exoplanet community!
Contact us with your CV and/or your questions: emeline.bolmont at unige.ch
We encourage applications from minorities, women, individuals with disabilities, and all other qualified applicants!

Ask HN: How Can I Make My Front End React to Database Changes in Real-Time?

Choosing Between a Streaming Database and a Stream Processing Framework in Python
To fully leverage the data is the new oil concept, companies require a special database designed to manage vast amounts of data instantly. This need has led to different database forms, including NoSQL databases, vector databases, time-series databases, graph databases, in-memory databases, and in-memory data grids. Recent years have seen the rise of cloud-based streaming databases such as RisingWave, Materialize, DeltaStream, and TimePlus. While they each have distinct commercial and technical approaches, their overarching goal remains consistent: to offer users cloud-based streaming database services.

Proton, a fast and lightweight alternative to Apache Flink
> Materialize no longer provide the latest code as an open-source software that you can download and try. It turned from a single binary design to cloud-only micro-service
Materialize CTO here. Just wanted to clarify that Materialize has always been source available, not OSS. Since our initial release in 2020, we've been licensed under the Business Source License (BSL), like MariaDB and CockroachDB. Under the BSL, each release does eventually transition to Apache 2.0, four years after its initial release.
Our core codebase is absolutely still publicly available on GitHub [0], and our developer guide for building and running Materialize on your own machine is still public [1].
It is true that we substantially rearchitected Materialize in 2022 to be more "cloud-native". Our new cloud offering offers horizontal scalability and fault tolerance—our two most requested features in the single-binary days. I wouldn't call the new architecture a microservices design though! There are only 2-3 services, each quite substantial, in the new architecture (loosely: a compute service, an orchestration service, and, soon, a load balancing service).
We do push folks to sign up for a free trial of our hosted cloud offering [2] these days, rather than trying to start off by running things locally, as we generally want folks' first impression of Materialize to be of the version that we support for production use cases. A all-in-one single machine Docker image does still exist, if you know where to look, but it's very much use-at-your-own-risk, and we don't recommend using it for anything serious, but it's there to support e.g. academic work that wants to evaluate Materialize's capabilities to incrementally maintain recursive SQL queries.
If folks have questions about Materialize, we've got a lively community Slack [3] where you can connect directly with our product and engineering teams.

We Built a Streaming SQL Engine
Some recent solutions to this problem include Differential Dataflow and Materialize. It would be neat if postgres adopted something similar for live-updating materialized views.
