How to Document Your Cassandra Database with One Command (and Nothing to Install)
You can save the output with an additional --output-file /share/schema.txt argument, and the file will be created in your local directory. schemacrawler help will give you more information, as well as the SchemaCrawler website. Now you are ready to connect to your own database. If you need help on how to construct the connection URL, take a look at ing-bank/cassandra-jdbc-wrapper.

SQLPage – Building a full web application with nothing but SQL queries [video]
Saving further clicks:
> SQLPage is a tool that allows you to build websites using nothing more than SQL queries. You write simple text files containing SQL queries, SQLPage runs them on your database, and renders the results as a website.
The 22-line "TinyTweeter" example at 28:45 [0] in the video is a good overview - perhaps better than anything currently on the homepage/docs: https://github.com/lovasoa/SQLpage/blob/main/examples/tiny_t...
Also, based on a couple of discussions [1][2] it seems like SQLPage has the potential to combine well with HTMX too. The two projects definitely share a similar philosophy.

Bruno
I am currently looking for a solution to run automated tests on a sql website generator I am working on ( https://sql.ophir.dev )
I wanted to use hurl (https://hurl.dev/), but Bruno's UI seems to be useful while developing the tests... Has someone tried both ? Which is better for automated testing, including when the response type is html and not json?

Apache Superset
Full fledged BI tools like Superset and Metabase are amazing for their intended use cases.
But they may be an overkill if your primary use case is to infrequently build semi-interactive reports for non-technical end-users and your use cases are are mostly covered by standard graphs & tables. Esp. so if you are familiar with SQL and have access to the underlying data source. Two nifty utilities I have found to be very useful for latter kind of use cases are SQLPage and Evidence.
They make it very convenient to whip out some SQL and convert that to a neat professional looking web ui that can be forwarded to an end user. In case of Evidence it is a statically generated site, and in case of SQLPage it is a web app that connects to a live database.

PostgREST: Providing HTML Content Using Htmx
I feel obligated to add a shameless plug here. The idea is very close to a project I presented at pgconf.eu last week: SQLPage
https://sql.ophir.dev/
SQLPage has the same goal as postgrest+htmx, but is a little bit higher level. It let's you build your application using prepackaged components you can invoke directly from SQL, without having to write any HTML, CSS, or JS.

I think I need to go lie down
It would be great if someone could open a github issue with reproduction steps and maybe a screenshot: https://github.com/lovasoa/SQLpage/issues
The worst I'm able to get when manually disabling the cache and simulating a slow 3G connection is this: a blank page first, then text in the browser's font, then the text re-renders with the right font, then the icons load. The user should never see completely unstyled content.
The site uses "font-display: fallback" so this happens only on slow network connections. If the font loads fast enough, then the fallback never appears.

Portugal. The Man – Official Website Is a Google Sheets Document
The official website for SQLPage (https://sql.ophir.dev/) is written in SQLPage.
The source code is here: https://github.com/lovasoa/SQLpage/tree/main/examples/offici...
The site also links to this little collaborative game written in SQLPage: https://conundrum.ophir.dev/
The github README has code snippets and associated screenshots: https://github.com/lovasoa/SQLpage#examples
There is also an official repl.it that you can fork to quickly try it online without having to download anything: https://replit.com/@pimaj62145/SQLPage
And SQLPage cloud is coming: https://sql.ophir.dev/your-first-sql-website/hosted.sql

Ask HN: What do you like to see in tech talks?
Hey HN community!
I'll be making my first ever presentation at a large tech conference at pgconf.eu this December, where I'll be presenting the SQLPage webapp micro-framework ( https://sql.ophir.dev/ ). I'm eager to make a lasting impression and deliver a presentation that truly resonates with the audience at the conference, who probably knows more about postgres than I do.
That's where I could use your insights. What makes a good tech talk in your eyes? Do you like seeing mind-blowing demos, deep dives into code, compelling storytelling, or something else entirely ?
If you have any specific advice, tips, or ideas for structuring a tech conference presentation, I'm all ears. I want to ensure that my presentation is not just informative but also an experience to remember.
Thank you in advance for your guidance and suggestion !

Show HN: A open-source financial accounting alternative to QuickBooks
When I see that, I always wonder whether this is part of the business plan of the people who distribute open source software for free, with a paid hosted version. There is some kind of a conflict of interest: the easier the software is to install and operate, the less attractive the hosted version.
I am working on an open-source software with a hosted version myself ( https://sql.ophir.dev ). It's a website builder, and I'm trying to make ease of deployment and operations a competitive advantage, which is marketed on the home page. But it may be idealistic to ask the same of others. My audience is mostly people who will have to operate the software themselves, whereas in most other domains, the people making the choice to use the software and the people who will then have to operate it are not the same.
What are some alternatives?
Mermaid - Edit, preview and share mermaid charts/diagrams. New implementation of the live editor.
dwarf - dwarf is a typed, interpreted, language that shares syntax with Rust.
datahub - The Metadata Platform for your Data Stack
bigcapital - 💵 Bigcapital is financial accounting with intelligent reporting for faster decision-making, an open-source alternative to Quickbooks, Xero, etc.
Hibernate - Hibernate's core Object/Relational Mapping functionality
duckdb-prql - PRQL as a DuckDB extension
marquez - Collect, aggregate, and visualize a data ecosystem's metadata
budibase - Budibase is an open-source low code platform that helps you build internal tools in minutes 🚀
plantuml - Generate diagrams from textual description
pugsql - A HugSQL-inspired database library for Python
H2 - H2 is an embeddable RDBMS written in Java.
self-hosted - Sentry, feature-complete and packaged up for low-volume deployments and proofs-of-concept
