voigton Every satellite orbiting earth and who owns them (2023)

Is there something like https://www.flightradar24.com for satellites?

Would be kind of interesting to build a “live” visualization of objects in earths orbit. But this would require accurate live data of those objects. Probably nothing that companies would publish.

On the other hand side: once the object and its orbit is identified, positions could be calculated…

Does anyone know more?

voigton Grammarly acquires Superhuman

> Superhuman valued at $825 million in 2021, $35 million annual revenue

This is nuts! I used Superhuman for about a year. And honestly, I might still be using it if the pricing weren't so off. It had a couple of nice features, and the keyboard-driven approach was a welcome change for mail clients.

But ultimately, Superhuman had nothing that couldn't be replicated in a relatively short amount of time (maybe even with plugins?).

$825 million? Maybe I should start a mail client company...

voigton Grammarly acquires Superhuman

Really miss Sparrow! To me it was the perfect email client.

voigton He has powered his house for 8 years using laptop batteries

I went to the comments to see if I was the only one who felt this way. I don't judge using AI to correct spelling or style issues, but this is just too much.

voigton Show HN: Kraa.io – Markdown editor for notes, blogs, chats

Appears to me more like a super clean version of hack.md!

voigton Building the Ultimate Pi Kubernetes Cluster: A Journey into Cloud Scalability

tl;dr: he used 4 raspberry pi 5s, and created a k8s cluster using microk8s.

There isn't so much value in this article, also not an explanation of how things were done...

The chosen case looks nice, but for a cluster of PIs it looks like the wrong choice.

In any case, seems like the author enjoyed his work :)

voigton Some Go web dev notes

> In general everything about it feels like it makes projects easy to work on for 5 days, abandon for 2 years, and then get back into writing code without a lot of problems.

To me this is one of the most underrated qualities of go code.

Go is a language that I started learning years ago, but did't change dramatically. So my knowledge is still useful, even almost ten years later.

voigton Fire Chicken Webring

This is the „beauty“ of web rings. Low tech, but brittle if not everyone plays to the rules xD

voigton Kris Nóva has died

I’m really sorry to hear this. She did so much for the community and was an inspiring personality. All the best to her family.

voigton Show HN: Hacker News user blogroll

Having the latest post of each blog available is an awesome, thank you for adding it.

Another killer feature on top would be to sort for latest post, so they can be ordered by date desc. This would make a great HN-meta news page :)

voigton Show HN: Hacker News user blogroll

I’m missing the good old time of webrings. This is very close :)

voigton Ask HN: Could you share your personal blog here?

https://christophvoigt.com/

My personal blog writing mainly about technical things such as Kubernetes (and Containers), WebAssembly or Zig. Lately I’m documenting my progress of learning the Rust programming language by taking notes on specific topics.

voigton Zellij New WASM Plugin System

I do understand why people try this approach:

First: wasm is the perfect plug-in language, as it provides a high level of isolation and therefore security for the host app.

Second: the promise of wasm is that you can write it in any language. I think this is compelling for any application that seeks for extensibility.

Wether all this is worth the effort is probably the actual question. Maybe we will be surprised by killer plugins that wouldn’t be possible with regular plug-in systems…

voigton Ask HN: Which ActivityPub software to use for a personal server?

I think it’s worth to check out https://github.com/superseriousbusiness/gotosocial It’s far from „done“ and has a lot of rough edges, but it’s easy to setup and probably good enough for a single instance!

voigton Zig 0.10.0 Release Notes

Congratulations on the release!

voigton GNU Make 4.4 released

I’m using Make for years now but usually only for very basic things. I always feel like it can do much more. Are there any good docs/books/articles about advanced usage of make?

voigton Scaling Kubernetes to Thousands of CRDs

A couple of KubeCons ago there was a talk about a "Kubernetes without Containers". The idea was to utilize Kubernetes' API and extensibility, without the necessity to run a container runtime.

I can not recall the name of the project. Would love to see whether this idea got any traction. Sounds like it would be a nice fit for a crossplane maintained infrastructure.

voigton Zig and WASM

Using Wasi (opening/reading/writing files) via zig: https://christophvoigt.com/zig-file-open-in-wasi-via-preopen...

voigton Zig and WASM

First reaction: chill, it’s a super basic example…

Looking closer to it: boy he didn’t even care to change the log message.

Thanks for the example meheleventyone!

voigton Game Boy Camera Canon EF Lens Mount (2018)

Is there any good smartphone app that emulates the Gameboy Camera? So far I found only some that promise but do not deliver...

voigton Zig, Hare, Odin, Vale, V, Jai

Plus: Zig brings a great Build System for (cross-)compiling. It’s very adaptable, so you can even build C, rust, go or whatever language…

voigton How I Built Zig-SQLite

I see Zig, I vote up ;) Exciting new language with compelling features!

Great work of the author explaining comptime!

voigton OP-1 field

I hope for 2k bugs it has at least an „undo“-button.

The classic op1 doesn’t have one. Would increase my productivity dramatically.

voigton Show HN: Run WASM in Containerd

> Included in the repository is a PoC for running a plain wasi host (ie. no extra host functions except to support wasi system calls).

Looks like that’s not decided yet.

In theory you could use pod.spec.volumes to hand it over to the shim for the wasi preopens.[1]

Whether that’s a good idea is the other side of the story…

voigton Show HN: Run WASM in Containerd

Great work! Nice to see some progress in this direction.

The WasmEdge team also tamed their crun OCI runtime to run containers as well as wasm modules. [1]

So running wasm along with your pods is not exactly new.

Though it yet needs to be proven what’s the better approach: a shim on CRI level or integration in OCI level…

voigton Strava abruptly ends 3rd party data sync to Apple Health

Is there any OSS/self hosted alternative to Strava? Where would be the challenges?

voigton Sonic Pi – Code based live music creation tool

I like the idea of sonic-pi and think its very well designed.

What I would like to see is a "multi-player" mode, where I can collaboratively code on the same session.

Is there anything that would enable this with sonic-pi?
