Working on https://canine.sh, an open source, self hosted PaaS for Kubernetes.

A big part of this was inspired by the last startup I worked at. In an effort to not deal with complexities of Kubernetes, we ended up on Heroku and was charged exorbitant amounts of money. One year spending close to 400k on Heroku alone, for what should’ve been 10-15k in cloud costs.

I think a big part of this is just making Kubernetes more friendly and easier to use for a small / midsized team of developers.

The goal is to make it easy enough for even a single developer to feel comfortable with, while also being powerful enough to be able to support a small team

Last week I spun up a HN clone for digital nomad news.

Since I was researching DNS and global mobility, and wanted to share links with others, figured I'd just spin up a link site (though I'm still the only user).

One unique difference is I have a field for English Title, since I consume a lot of Korean & Japanese articles and want to share these, but don't want to have people translate the titles before they understand why they should read them.

I’m working on Paperboy (https://www.paper-boy.app/) a self-hostable service that generates a personalized daily research digest from recent arXiv papers (and optionally a few other sources).

It fetches new papers, scores them against a “research profile,” then produces concise summaries plus a short “why this matters” style rationale, and outputs an email/newsletter-like HTML digest. There’s also a small API for generating a digest, checking status, and previewing the render.

I built it because keyword alerts and generic newsletters were either too noisy or missed the stuff that was actually relevant to what I’m working on right now.

I’ve been building a crypto market visualization and simulation tool because I kept running into the same problem: TradingView is great for charts, but it’s hard to answer simple “what-if” questions like would rotating into another coin actually have helped or did trimming and buying back improve outcomes, or just feel good in hindsight. So I started building tools that simulate these scenarios directly on historical data. For example: - flipping from coin A into coin B and back again over a chosen period - selling part of a position and buying back later after a drawdown

I’m still early and adding ideas as I go, but it’s already helped me questions I had.

Examples: - Coin flip simulation: https://www.blockviz.xyz/simulation/coin-flip - Sell & buy-back simulation: https://www.blockviz.xyz/simulation/sell-buy-back

Curious if others here run into similar “this felt right, but did it actually help?” questions.

I am learning C++ and ImGUI. My first app is a JSONL Viewer. Recently I‘ve added support to read parquet files (uncompressed) too.

https://iotdata.systems/jsonlviewerpro/

Next step is to integrate a visual data pipeline by using ImNodes. I‘m slowly making progress in my experiments, but C++ has a steep learning curve, especially when targeting MacOS and Windows at the same time.

Personal feed curation for events+more.

It feels like somewhere in the last decade we've all lost control over our email inboxes. While it would certainly be possible to filter and sort it, I've been wondering if it makes sense to just start with a system that is designed to intake a bunch of streams of information. Then it could be pointed at the raw information e.g event calendars and news-letters as well as streams like Facebook groups/Instagram where I don't want to actually go to those apps.

Speaking at a meta-level, this seems like what we should really be using LLMs for right now: use-cases where user controls what is done on their behalf.
