Show HN: I built a JavaScript-powered flipdisc display

> near limitless lifespan

The lifespan is probably not as limitless as you might have imagined, the discs tend to fall off or get stuck. But they are really neat while they are working, especially how they sounds.

I was at an office with these flip dot displays, and eventually we dismantled the display. I took some picture of the pieces and you can see how stuck discs look like:

Show HN: Glasskube – Open Source Kubernetes Package Manager, alternative to Helm
github.com - 3 Comments

This looks like an interesting take on package management. Would be cool for homebrew clusters and the like.

However things like helmfile with renovate paired with a pipeline is my personal preference even if just for ensuring things remain consistent in a repo.

The `update all` button for instance seems terrifying on a cluster that means anything at all. None the less it's still cool for personal projects and the like!

I found a 1-click exploit in South Korea's biggest mobile chat app
stulle123.github.io - 5 Comments

Reminds me how the telegram founder boasted how talented his team is as only one developer was responsible for writing the mobile client. Turns out that client was riddled with bugs that displayed messages to the wrong user. A mobile chat app shouldn't be developed with the mantra "move fast and break things" yet this is the natural product result of all-in-one apps like kakao.

Show HN: Triplit – Open-source syncing database that runs on server and client
github.com - 11 Comments

We’ve been using triplit to store user settings that can be managed by admins, it’s important users always feel like the app runs locally and they often don’t have good internet but we still needed sync as the users often switch devices and admins need to see and manage other users settings.

Overall triplit has been really great, both as a frontend dx and also their support - whenever we find an issue or have a feature it gets handled very quickly by the team which is awesome!

As soon as they have an answer for HA deployments we will be moving more critical data there instead of Postgres

From Dotenv to Dotenvx: Next Generation Config Management
dotenvx.com - 28 Comments

I _detest_ this kind of encryption. It's literally worse than useless. It makes life much harder during debugging, and it eventually leads to developers just storing the decryption keys locally.

For this kind of encryption to work, you need to supply the decryption key from some outside system (e.g. via env vars, AWS SSM, etc.). And if it can supply the key, then why not just use it for other important secrets directly?

Chang'e 6 lunar sample return mission returns with samples from moon's far side
www.theguardian.com - 4 Comments

One thing they seems to have got working fairly reliably is the lunar landing of the probe using image processing to guide the final approach and touch down. It seems to have worked well in this and the previous mission, there are videos on youtube of that.

The other component is the autonomous docking of the return probe in lunar orbit.

Soviets have done a lunar sample return, but they had a probe that would lift off directly into a earth return trajectory, but that seems to have limited both the liftoff mass and the possible zones in moon from which it can lift off.

Testing AMD's Giant MI300X
chipsandcheese.com - 14 Comments

Impressions from last week’s CVPR, a conference with 12k attendees on computer vision - Pretty much everyone is using NVIDIA GPUs, and pretty much everyone isn’t happy with the prices, and would like some competition in the space:

NVIDIA was there with 57 papers, a website dedicated to their research presented at the conference, a full day tutorial on accelerating deep learning, and ever present with shirts and backpacks in the corridors and at poster presentations.

AMD had a booth at the expo part, where they were raffling off some GPUs. I went up to them to ask what framework I should look into, when writing kernels (ideally from Python) for GPGPU. They referred me to the “technical guy”, who it turns out had a demo on inference on an LLM. Which he couldn’t show me, as the laptop with the APU had crashed and wouldn’t reboot. He didn’t know about writing kernels, but told me there was a compiler guy who might be able to help, but he wasn’t to be found at that moment, and I couldn’t find him when returning to the booth later.

I’m not at all happy with this situation. As long as AMDs investment into software and evangelism remains at ~$0, I don’t see how any hardware they put out will make a difference. And you’ll continue to hear people walking away from their booth, saying “oh when I win it I’m going to sell it to buy myself an NVIDIA GPU”.
