LaTeX and Neovim for technical note-taking
I use Anki the exact same way. After a lifetime of learning I have accepted that I will never read over anything I write for myself voluntarily - so my two options are:
1. Write an article so good I can publish it and look it over myself later on. I did this last year with https://andrew-quinn.me/fzf/, for example.
2. Create Anki cards out of the material. Use the builtin Card Browser or even https://datasette.io/ on the underlying SQLite database in a pinch to search for my notes any time I have to.

SQLite-Web: Web-based SQLite database browser written in Python
Datasette [0] is worth mentioning in this context since I didn't know about it until the second half of last year.

Ask HN: What two software products should have a kid?
Browsing HN, GitHub and the like we get to see a huge variety of software products and code bases.
I often see products and think - if this product X, got together with Y, it would be pretty cool - kind of like if they had a kid together.
Not too literally, but more on the conceptual level - my level of programming is low.
E.g. Just some....

Ask HN: Looking for a project to volunteer on? (February 2024)
You might like the Datasette project: https://datasette.io/
I don't think they are desperate for contributions but it's a welcoming environment and a fun project to hack on. You'll learn a lot just from reading the source and the incredibly informative PRs. The creator is a really talented developer with a great blog which shows up on the HN front page often.

What is Glamorous Toolkit v1.0?
OK, having watched the video at https://www.youtube.com/watch?v=lqogvp1dGpk (8 minutes, so 4 minutes if you 2x it) I understand why they have such a hard time answering the question "What is Glamorous Toolkit?"
It's effectively a combination of a Smalltalk IDE, a Jupyter/Observable-style notebook environment and a tool somewhat like R Studio.
It's a hard thing to categorize, because it's not exactly the same kind of thing as anything else.
I emphasize wit the challenge: I have a similar problem with my https://datasette.io/ project.

How (and why) to run SQLite in production
This presentation is focused on the use-case of vertically scaling a single server and driving everything through that app server, which is running SQLite embedded within your application process.
This is the sweet-spot for SQLite applications, but there have been explorations and advances to running SQLite across a network of app servers. LiteFS (https://fly.io/docs/litefs/), the sibling to Litestream for backups (https://litestream.io), is aimed at precisely this use-case. Similarly, Turso (https://turso.tech) is a new-ish managed database company for running SQLite in a more traditional client-server distribution.

SQLite3 Replication: A Wizard's Guideπ§π½
This post intends to help you setup replication for SQLite using Litestream.
wget https://github.com/benbjohnson/litestream/releases/download/v0.3.13/litestream-v0.3.13-linux-amd64.deb sudo dpkg -i litestream-v0.3.13-linux-amd64.deb

Pocketbase: Open-source back end in 1 file
Litestream is a library that allows you to easily create backups. You can probably just do analytic queries on the backup data and reduce load on your server.

Why you should probably be using SQLite
One possible strategy is to have one directory/file per customer which is one SQLite file. But then as the user logs in, you have to look up first what database they should be connected to.
OR somehow derive it from the user ID/username. Keeping all the customer databases in a single directory/disk and then constantly "lite streaming" to S3.
Because each user is isolated, they'll be writing to their own database. But migrations would be a pain. They will have to be rolled out to each database separately.
One upside is, you can give users the ability to take their data with them, any time. It is just a single file.

Monitor your Websites and Apps using Uptime Kuma
# Builder image FROM docker.io/alpine as BUILDER RUN apk add --no-cache curl jq tar RUN export LITESTREAM_VERSION=$(curl --silent https://api.github.com/repos/benbjohnson/litestream/releases/latest | jq -r .tag_name) && curl -L https://github.com/benbjohnson/litestream/releases/download/${LITESTREAM_VERSION}/litestream-${LITESTREAM_VERSION}-linux-amd64.tar.gz -o litestream.tar.gz && tar xzvf litestream.tar.gz # Main image FROM docker.io/louislam/uptime-kuma as KUMA ARG UPTIME_KUMA_PORT=3001 WORKDIR /app RUN mkdir -p /app/data COPY --from=BUILDER /litestream /usr/local/bin/litestream COPY litestream.yml /etc/litestream.yml COPY run.sh /usr/local/bin/run.sh EXPOSE ${UPTIME_KUMA_PORT} CMD [ "/usr/local/bin/run.sh" ]
Upstream Kuma uses a local SQLite database to store account data, configuration for services to monitor, notification settings, and more. To make sure that our data is available across redeploys, we will bundle Uptime Kuma with Litestream, a project that implements streaming replication for SQLite databases to a remote object storage provider. Effectively, this allows us to treat the local SQLite database as if it were securely stored in a remote database.

Litestream is a game changer allowing to backup all your changes to a an s3 compatible cloud storage at 1sec intervals using the WAL all done via the API and not interacting with the DB itself to avoid corruption or impacting performance.
