Show HN: DBOS Java – Postgres-Backed Durable Workflows Hi HN - I’m Peter, here with Harry (devhawk), and we’re building DBOS Java, an open-source Java library for durable workflows, backed by Postgres. https://ift.tt/gATmXYf Essentially, DBOS helps you write long-lived, reliable code that can survive failures, restarts, and crashes without losing state or duplicating work. As your workflows run, it checkpoints each step they take in a Postgres database. When a process stops (fails, restarts, or crashes), your program can recover from those checkpoints to restore its exact state and continue from where it left off, as if nothing happened. In practice, this makes it easier to build reliable systems for use cases like AI agents, payments, data synchronization, or anything that takes hours, days, or weeks to complete. Rather than bolting on ad-hoc retry logic and database checkpoints, durable workflows give you one consistent model for ensuring your programs can recover from any failure from exactly where they left off. This library contains all you need to add durable workflows to your program: there's no separate service or orchestrator or any external dependencies except Postgres. Because it's just a library, you can incrementally add it to your projects, and it works out of the box with frameworks like Spring. And because it's built on Postgres, it natively supports all the tooling you're familiar with (backups, GUIs, CLI tools) and works with any Postgres provider. If you want to try it out, check out the quickstart: https://ift.tt/eau3TdS We'd love to hear what you think! We’ll be in the comments for the rest of the day to answer any questions. https://ift.tt/gATmXYf November 14, 2025 at 03:33AM

Show HN: Guish – A GUI for constructing and executing Unix pipelines https://ift.tt/HrXz5ub

Show HN: Guish – A GUI for constructing and executing Unix pipelines guish is a dynamic data pipeline UI that allows users to visually construct and execute complex command-line pipelines. It provides an intuitive interface for chaining together various Unix commands and custom plugins, making it easier to build and understand data processing workflows. It also features optional LLM support for updating pipelines with a natural language interface. https://ift.tt/2lsA0r5 August 2, 2024 at 10:00PM

Twin Peaks for All: Survey Results

Twin Peaks for All: Survey Results By Benjamin Barnett Last month, the SFMTA and San Francisco Recreation and Parks Department released a survey seeking public feedback regarding  five proposed roadway options for Twin Peaks Boulevard . San Franciscans responded to the survey, ranked support for each alternative and shared opinions about how the different options met their needs.  The Twin Peaks for All survey was open for almost three weeks and received more than 1,700 responses. This number reflects the high level of interest for this San Francisco park and its future access.   Survey Background Conditions on Twin Peaks Boulevard between Portola Drive and Barnett Avenue before COVID street closures.   The Twin Peaks Boulevard gates were closed early in the pandemic to reduce crowding at the lookout point parking lot. The gates were closed on the north, at Burnett Avenue, and the south, at Portola Drive. Since then, Twin Peaks Park use by hikers, joggers and peopl...

History in Motion: New Photos from the 1960s to 1980s Now Online

History in Motion: New Photos from the 1960s to 1980s Now Online By Jeremy Menzies We’ve been hard at work in the SFMTA Photo Archive and recently uploaded two large collections of photos from the early 1960s to the 1980s to our website. These photos, both color and black and white, give a glimpse into the day-to-day operations of Muni and the streets of San Francisco. Here’s a selection of shots from this brand-new batch of photos, many of which have not been seen outside the Photo Archive in years.  This shot shows a typical evening rush hour scene from the mid-1970s taken at Market and Powell Streets.  The color photos from this era are all part of a collection that was most likely used for presentations, studies and as general “stock” type photos of San Francisco, streets and Muni facilities and operations. Subjects include project documentation, copies of maps and charts, street...
