Pi Reliability: Reduce writes to your SD card
My SD protection script, a few months old and may need some updates since a lot seems to have changed in Pi OS:
https://github.com/EternityForest/KaithemAutomation/blob/mas...
Current version doesn't disable swap, that's in a separate optional file, but the next version will.
It can't be done in a one size fits all script unless you're launching chromium the same way, but do something like:
-
Running a Raspberry Pi with a read-only root filesystem
I don't usually do full read only, what I'll do is run a script that turns off stuff that does not need to be writing to the disk all the time.
Unfortunately, some software is database-oriented and likes to write to disk for every tiny thing, so the approach doesn't work with stuff like Home Assistant unless you carefully configure logging.
The basic simple stuff doesn't really cause any user-level noticable changes:
https://github.com/EternityForest/KaithemAutomation/blob/mas...
After that, I disable and mask apt-daily (The Debian auto updater), and purge dphys-swapfile.
My full set of assorted tweaks can be found here, some might not be relevant for you:
https://github.com/EternityForest/KaithemAutomation/blob/mas...
Next, I often run Chromium as a kiosk, and Chromium likes to hammer the SD card, so I set the XDG folder environment variables to make it put it's stuff in RAM. My embedded chrome stuff can be found here:

Raspberry Pi availability is visibly improving after years of shortages
Things like that are easy enough to set up on Raspbian with a script. You also need a bunch of tmpfs mounts, including some in crazy places(Regular Pi has a log file under ~/.cache that can fill disks and crash servers, and if you don't fix it Chromium writes seemingly useless crap constantly. There's auto updates on some systems, which is terrible if you're on a private WiFi, not doing internet stuff.
I'm not using zram at the moment, just getting rid of swap, but my current script to get a Pi ready for embedded projects is here: https://github.com/EternityForest/KaithemAutomation/blob/mas...

Ask HN: What have you created that deserves a second chance on HN?
The only FOSS thing I've done that I think is really worth telling people about is KaithemAutomation, a home automation server in pure Python with a bit easier setup than Home Assistant, and some features aimed at commercial installs like room escape control, and some pretty decent network video recorder features.
https://github.com/EternityForest/KaithemAutomation
I put 6 years or so into it, and have used it on plenty of contract projects, but so far I don't think anyone else is interested.
Possibly because it's largely UI and CRUD over existing functionality, and there's not much particularly exciting to the hacker community, few interesting algorithms, it's not minimalist at all, etc.
Plus it has a lot of dependencies that might or might not exist outside of Debian, I've never looked into how it would run on the more DIY distros since I've never used them.

Ask HN: Practical examples of runtime modified software
pure Python and heavily built around runtime modification(https://github.com/EternityForest/KaithemAutomation), and is designed to run for months, although it's not meant to be modified literally while running production(Not that that stops us from making last minute fixes...).
The big problem with it in Python is state. If you have a reference to something, and that something changes, and you have a reference to the old one, that should be a singleton, you are probably in an unhappy position.
The only way it can work in real life(In Python at least) is if you carefully design for it, and don't pass around objects and callbacks and stuff.
I have gone through several iterations of abstractions trying to make updatable objects and such to hide this from you, and none were very good.
I eventually settled on a message bus, and a data structure I'm calling a Tag Point adapted from the SCADA industry, which is like a variable, but you can subscribe to it, and spy on the value from the web UI, it stays around as long as there is a reference to it, and it's guaranteed that any tags with the same name are the same object, and a bunch of other stuff.
Files of code are essentially meant to be used like stateless microservices if you expect to update one, and if you want to access shared stuff, you make sure to not hold a reference to it.
A lot was(and some still is) based on weak references, and those can trouble and should probably not be relied on for correctness if possible.
They aren't the worst things though. I have code to run a few GC sweeps when a file is deleted, and it is extremely rare that anything stays around when it shouldn't.
Good enough for development, good enough for emergency fixes, not the best for regular updates to running systems, although it's 99.9% fine, and I can't say I really worry about it(But future versions should be more deterministic and more suited for live edits as a regular practice).
Erlang seems to like its functional-ness and I imagine that's a huge asset. Language level support is definitely a good thing.
Random unstructured code doesn't seem to work well with live updates.
If you are working in a general language like Python you really want to have your engine always know exactly what's going on, what subscriptions come from what module and which function is replacing what, etc.
You want to deterministically always be able to list any changes that a module made to anything else(Like subscribing to a function), and undo them.
But... weak refs work well enough.
The classic solution to tech problems is to reboot, live updates are kind of the opposite of that. Your new code has to perfectly pick up with what you keep from the old state, and if the old state is invalid somehow you have to deal with that too.
I've never heard of smalltalk as a live update language(In the Erlang telephone exchange sense), just that you can do interactive development in it, which is a lot easier.
I think if I intended to seriously to true live updates(Like phone exchanges not dropping active calls), I would really appreciate tools made for that.
Kaithem also does have a module with a visual script explicitly meant for changes in production. It's very limited and opinionated, essentially a state machine with event triggered actions attached to states, and variables at the state machine level.
That kind of transition rule system for simple tasks is very easy to live update. State is well separated from rules, and rules are simple and easy to parse programmatically, to do things like clean up after yourself if an event listener needs resources.
But just about any interpreted language works for interactive development.
A lot of people like FORTH for that, which I don't have any interest in learning but some love it.

A Clutter-Free Life: Going Paperless with Paperless-Ngx
We may want to get in touch with each other. We have an Open Core document management platform that runs in AWS; I'm not sure about your roadmap, but there may be something there that's of use: https://github.com/formkiq/formkiq-core

It seems like almost everyone here is working on a SaaS for other SaaS bootstrappers —- is anyone building a product for a vertical outside of email/marketing/forms/dev tools/productivity?
We are in the weird position of building something (a document management platform) that can be for SaaS bootstrappers (especially our free version), but our main marketing and sales efforts are for larger orgs, whether for SaaS or internal use.

Anyone using AI for enterprise content management?
We have a free offering, FormKiQ Core (https://github.com/formkiq/formkiq-core) that will also include this AI classification, so it's possible to use that as a foundation for creating a custom ECM system.

[D] Is there any way to filter searches by metadata over current vector DBs like Pinecone?
I think that makes sense to me (biased as I am). I wonder if Milvus (mentioned in another comment) can handle some of this, or if a dedicated EDMS is required. We have created an Open Core EDMS that could provide the document management functionality running using AWS: https://github.com/formkiq/formkiq-core

Does anyone have ideas on how to reach out to other startups to pitch our startup program?
Our product is FormKiQ, and while our free version, FormKiQ Core, handles all of the standard functionality, we want to get our enterprise modules out there for startups that could use them.

Email filing & automation methods & systems
I'm definitely curious as to what software is available in this space. Our company, FormKiQ, is wading into this AI processing of emails into matters right now, and I don't know that I've personally seen anything with the flexibility you need on the market. We may be too robust for what you need, but I'm always looking out to see if there is a simpler solution we can provide if enough people have the same problem.

Can anybody recommend a document management system?
If hosted in-house can be swapped out by an AWS account your organization owns and controls, you can try FormKiQ Core: https://github.com/formkiq/formkiq-core. It covers all of the expected standard functionality of a document management system, with an emphasis on flexibility and integration.
