When I was digging into Container (a.k.a it uses linux namespace capabilities) lwn.net's series of article helps me a lot.

Is the Solid State Battery claimed by Mercedes-Benz safer than the batteries currently used in EVs? In 2024, a Mercedes electric vehicle caught a major fire in my country (South Korea), which has led to a rise in electric vehicle phobia and even places where parking is completely prohibited.

If you read the article it will answer your question in the first paragraph

Oh, I see. Thanks.

EV’s catch fire at a far lower rate than gas vehicles.

> What stateful apps are you running?

- Databases. (Usually PostgreSQL, seems like it's pretty easy to setup to replicate between PostgreSQL instances.)

- Qdrant, or milvus. (seems like they're support replication between instances, we've *accidentally* running a replicated DB on Single Ceph Cluster)

- Some user generated contents. (usually from Jupyter Environment)

> Sounds like you want to do your own storage infra?

We don't actually have a "storage infra". it's just a bunch (I really don't think 2 HDD is a part of "Bunch") of disks attached to each machines (or node).

So it sounds like you have state replication at the application at the service level for everything but Jupyter? I'm not familiar with Jupyter but would it be possible to use object storage? Does it support backups? Can you store those backups off site?

How to choose the base operating system for `home-manager`? I've suffering a LD error on Ubuntu.

It should have the same constraints as nix itself — i.e. easiest on linux, slightly more complicated on macos.

Bug isolation is probably the best next step for you. Is it during nix installation? Is it a particular package that thows an error?

There's some community at #hm:rycee.net, perhaps they can help you debug it live.

It feels like they're leverage Firecracker (MicroVM)'s Snapshot functionality to Hibernate and faster resume.

Very cool.

When I use Search supported LLM service, I've always do this question by myself.

1. What's the source of the Search?

2. Do they crawl any website to make an Index?

When I compare search results with Google (or alternatives) it shows some similar results. I hope it's just a part of happening for me.

For the source of the Search, it is shown in ChatGPT Search, so you can check it / get the link. On the index part, there is certainly some indexing, but it is on a small subset as I understand it (only "partners").

How can I manage different projects with different nix package version without `flake`?

Wow... Really great.

Can you add some historical archive to listen n hours ago (or morning briefing like) summary as a feature?

Thanks! An archive shouldn't be too hard to implement.

Would a morning briefing include more of a curated selection of news, like the most interesting/most discussed news of the day? Currently I just take the top 5 posts from the main page.

I could easily see listening to such a summary once or twice a day. Considering the pace at which HN is updated, how about two to four somewhat longer episodes per day, with an archive of the past week so that people can catch up? You might also want to focus on certain types of stories, such as those with more upvotes or comments.

In any case, it's a great idea, and I enjoyed listening to the current episode.

Not just the top five, more like http://www.daemonology.net/hn-daily/ which also ensures newness.

Because of that, catching up on several days will also be unique stories.

That's a real useful resource. Thanks!

I was looking into using the algolia API to get the top 10 posts of the last day, but those won't be unique over the span of several days.

A daily update on the best posts of the last 24 hours would be amazing: https://news.ycombinator.com/best

Yeah. You're right.

My morning routine is Checking HN with Coffee. So with your service I can minimize some time to click around and figure out what the root cause is.

I was actually listening to it while making breakfast as well, so the idea of an extended morning briefing resonates with me. I'll look into it, thanks for the follow-up!

If you do this, it might be interesting to publish this as a podcast. Hourly is too frequent for a podcast, but daily would be pretty good.

(Podcasts are just RSS feeds.)

Sounds good, I'll get back to you about that!

Podcast/RSS seems like ideal distribution tool?
