Show HN: Stanchion – Column-oriented tables in SQLite https://bit.ly/49ij1oi

Show HN: Stanchion – Column-oriented tables in SQLite Hello HN! I built stanchion to scratch my own itch. I have personal applications running on SQLite where I want to store log and metric data (basically forever) but don't want to add complexity by bringing in a new database or whole separate server. Some of these applications are running on a Raspberry Pi, where storage and compute are limited, but I still want data warehouse like capabilities. I envision stanchion being used in similar scenarios: on phones and resource-limited devices in applications that are already using SQLite. I know that there are alternatives like DuckDB (which is very cool), but I want stanchion to be "good enough" that it is useful without having to add whole new database technology. If you think stanchion may be a good fit for your use case and you are interested in contributing, please test it and provide feedback by opening issues for any bugs, difficulties, or missing features you would need! Ideas are also welcome in this thread or as a github issue. Of course stars are always appreciated as well. The CONTRIBUTING doc in the repository has more details. - Dan https://bit.ly/497CXKG January 31, 2024 at 07:38PM

Show HN: FrequentlyAskedAI – An interactive AI FAQ alternative to chatbots https://bit.ly/499O1aJ

Show HN: FrequentlyAskedAI – An interactive AI FAQ alternative to chatbots I originally released an interactive resume tool and that went well but I got pulled in another direction by HN. HN really slammed my server on the original thing I built (thanks for the unexpected but useful battle testing, I learned a lot). More importantly some people reached out and said they wanted to use it for their business, not professional networking, which led me down a completely different path for a different tool using similar tech. Long story short, these businesses: 1) Wanted to know more about what their customers wanted but couldn't necessarily rely on customers reaching out to them 2) Spent more time answering similar questions than they'd like 3) REALLY hated chatbots and didn't want to pay for/train customer service agents yet I added a bunch of features they asked for like being able to embed my tool on their website, customize the quick questions, and add related links that can route their customers to other URLs. That last feature request was particularly interesting. Two businesses independently asked for this and they used it to basically make a mini Google search for their complex product (e.g. to direct customers to the right help pages, tutorials, etc). I have no idea where this project is going to end up yet and it's already turned in a direction I didn't expect. I'd love y'all's thoughts on the latest. Here's a link to my new home page with more information: https://bit.ly/3HBnc2Z Forgive me for lack of visual elements and some of the corny marketing text. Many are placeholders and I'm working on it. Also shout out to the business owner that went out of their way to find me this relevant domain name. We were joking that my tool should actually be called InfrequentlyAskedAI since it actually handles a long tail of questions. https://bit.ly/3vYgAcp January 30, 2024 at 10:33PM

Show HN: Privacy-first cross platform spreadsheet pipeline app https://bit.ly/48KVAnT

Show HN: Privacy-first cross platform spreadsheet pipeline app In my previous role at a small startup, I frequently developed simple scripts to assist recruiters and marketing professionals in handling data processing tasks on Excel or CSV files. These tasks were typically straightforward and repetitive, stemming from the periodic export of data. This experience sparked the idea to create a straightforward tool dedicated to such functionalities(also mobile friendly, as they occasionally need to process data on their smartphones). There are powerful tools like Power Query and Tableau, but they often prove too complex for non-technical users to navigate effectively. Additionally, ETL tools that support CSV/XLSX formats often come with a high price. That's why I build Tablesmith, an easy-to-use and free spreadsheet automation tool that empowers anyone to automate their data-related tasks with ease. Furthermore, I also include AI autofill capability, which I believe would be useful. https://bit.ly/47Woosf January 29, 2024 at 03:54PM

Show HN: Oasis, the community tech collective building an advocacy flywheel https://bit.ly/3SDaCqg

Show HN: Oasis, the community tech collective building an advocacy flywheel Hey everyone, I wanted to share the project I recently launched called Oasis, which is a community-driven tech collective with the focus of driving social advocacy by creating a self-sustaining flywheel of open-core projects that feeds into our various social advocacy initiatives. The governance is set up much like Open AI, where Oasis is the non-profit that handles the social advocacy and acts as an umbrella for the various OSS projects, and we have a collective structure of contribution with shared ownership so everyone who is working on a project, while it being OSS, gets to share in the financial success. We're 100% community driven, and anyone can join the Slack workspace now and contribute to any of the repos, but to actually be an "owner" we do require a $200/yr membership fee to help offset operational costs of adding users. All the projects we work on are thoroughly researched for profit potential and technology stack, and currently the angle we've been focusing on a lot of finding closed-source software and essentially ripping their features out into open-core versions. Tangentially, if you have a software you'd love to see a open-core version of then add a comment in here for sure. We're mainly been playing with simple CRUD apps but should the collective grow there's potential for other types of projects. https://bit.ly/47U18LA January 30, 2024 at 02:46AM

Show HN: Pruvious – A CMS for Nuxt Hi HN! Throughout the past year, I have been building a CMS for the Vue framework Nuxt. It started as a side project for myself, where I was trying to develop a decent block/content builder for my client websites. It was fun creating stuff, and it ended up as a fully featured CMS ready to replace my current WordPress projects with something much more enjoyable to develop with. It's free (MIT) and open-source. I'm here to answer all your questions. Thanks for reading! Muris :) https://bit.ly/3Uj1eJC January 29, 2024 at 05:54PM

Show HN: 12-colored visual interactive music theory for pop/rock MIDI (+Github) https://bit.ly/3OllSF5

Show HN: 12-colored visual interactive music theory for pop/rock MIDI (+Github) I'm sharing an early prototype of my open-source interactive book and MIDI viewer. My approach is to annotate a tonic and phrasing in each file, so that chords become visible as 3-4 color bundles after a bit of training. This radically simplifies seeing and hearing chords, so that you can rapidly browse through many arrangements and study Western harmonic/arrangement language If you don't have a touchpad, a horizontal scrolling can be done via shift+mouse wheel (generally on the web). Also, I have a second color scheme that I tried to optimized for people with color vision deficiencies. My big dream now is to have all piano rolls in DAWs support 12-coloring (in any color scheme really), so that the music can be seen as less complex, less gatekeeped and less entangled. It's not as hard as I've seen it before. Source code: https://bit.ly/3uhWid9 It currently doesn't play music from Russia or Türkiye (=requires a VPN), because I rely on corsproxy.io internally which blocks access from those countries. I plan to rehost stuff on S3 soon to fix that. Also, it's more performant in Chrome than in Safari - audio clicks less. === Backstory: I quit Whatsapp in 2021 to focus full-time on studying music theory. Along that I've assembled a list of resources to see the frontier: https://bit.ly/3vMcZhi My biggest inspiration is Hooktheory - an interactive book that teaches how melody and chords interact in Western pop music. After it I wanted to study how the rest of the arrangement works - what the bass line is doing, how is melody doubled, what chromatic chords are possible, are there any functional pre-dominants and dominants in mixolydian or dorian etc. I wanted to focus on music for which the complete arrangement is clean and available. This is early chiptune (NES/Genesis) OSTs and MIDI arrangements (primarily created in 1990s). As I plugged MIDIs into my front-end, I discovered that the harmonic analysis - the cornerstone of studying Western harmony - can be done by eyes in real-time. That is, if you color the notes consistently, the chords start to stare at you, sharply and memorably. I'm intrigued by latest shifts towards corpus studies in music theory and I'm generally happy that nowadays the research is not just about classical music anymore. At least in the West. https://bit.ly/3Okbuxg January 28, 2024 at 02:37PM

Show HN: WAYF – A Simple Scheduling App https://bit.ly/3SeGKyX

Show HN: WAYF – A Simple Scheduling App A dead-simple web app to find the best time for your next meetup with friends. No logins, no bloat. Schedule with a link. --- When trying to schedule events with my friends, we often have a long text thread of sporadic dates and the group has to mentally combine all the messages to produce a date that works for all. There are plenty of apps out there to coordinate scheduling, but I found many of them were bloated with features that didn't matter to us, required user sign ups and app downloads. This friction is enough for us to prefer rudimentary long text threads. I wanted something that I could post in the thread once, my friends can add their availability on their own time (and can edit), and we can continue on our conversation. WAYF (When are you free?) is a fun side project that solves this issue. Bare-bones scheduling for what days you are free. No user accounts, no downloads, just paste a link and anyone can schedule. It's completely free. I hope you like it and find it useful, I would love feedback. https://bit.ly/42jqtNC January 28, 2024 at 12:39AM

Show HN: HNRelevant – Explore Related Discussions on HN in an Integrated Sidebar https://bit.ly/3Ui8a9H

Show HN: HNRelevant – Explore Related Discussions on HN in an Integrated Sidebar Reading submissions here, I often feel intrigued and want to explore more interconnected or similar stories. The process of googling and going back and forth didn't feel natural. So, I made this browser extension that adds a related submissions section for HN's layout. The results are displayed in a sidebar right in the page's layout using HN native style just like other elements. I enjoy being knee-deep in discussions. Many times you're learning about something new, where the topic is either unfamiliar, thought-provoking, or just could use some context that you don't even know about. If a submission is interesting enough for me to click on, chances are I'd like to dig deeper into this topic and there are more related discussions that offer new context or perspective. This is an extension that I always have on so I paid special attentions to UX to make it intuitive and seamless and now the extension has become just part of the HN experience for me. Implementation-wise, it integrates https://bit.ly/4b8mY0R API and uses the submission title as its initial query with the ability to change the query and other options interactively. It's available on: Chrome, Firefox, and as a userscript. Chrome: https://bit.ly/3UhNqPr ... Firefox: https://mzl.la/3vPDmTM I shared it earlier last year when it was early in development, barely a prototype, at the time it wasn't yet published and could only be used on chrome by "load unpacked": https://bit.ly/43aGmG1 . I've been using it daily since and I'm happy to share it now for you to give it a try. https://bit.ly/432w2jf January 27, 2024 at 11:39AM
