I’ve been playing around with aligning drone footage to flight paths. I'm really interested in the idea of representing a video as a volume, planning to do something similar with non-drone video too.

We use this for summarising our hack day write ups: https://remotehack.space/previous-hacks/

It's a tiny script that looks up the rss feed and uses the content to generate summaries; quite a nice fit with our static site. Sometime I'd like to extend it to ask different questions about the content.

Yep. When the credentials were used earlier on in the session they'd been scrubbed from the logs - so there's some checking, but not on the code that's committed.

I was manually reviewing when I saw it. Was looking through the PR more out of interest than worried that there'd be a problem tbh.

If you pair this with a eink display you could send messages back and forth with another device https://remotehack.space/QR-TX/

Show HN: Video Space, pose-aligned video playback

I’ve been playing with an idea for rendering video in the 3d space that it was captured. It’s an idea that I’ve been thinking about for a while, and it’s been fun to finally get it working.There’s more info in the post. Tldr, I used COLMAP to extract camera poses from video frames, then three.js to align and render the video textures.I'm happy with how the content is loaded, it uses a video...

I've been working on https://stacks.camera - it's an idea about overlaying the previous picture when you're taking a photo so you can create a timelapse or animation.

For example, you can scroll through 60 pictures from my window https://stacks.camera/u/ben/89n1HJNT

Most of the challenges are around handling images & rendering, but I've also been playing with Passkey-only authentication which I'm finding really interesting.

Re:Remote Hack – A monthly online hackday on Wednesday January 27, 2021 @02:43PM (#25932924)
We've been running this since March last year.

It started as a "traditional hack day" with themes, teams etc, but we've morphed it into a more casual get together with random people working on fun stuff. We'd love to get more people involved!

Re:CoJS – Broadcast/follow JavaScript editor on Friday August 12, 2016 @08:18AM (#12274989)
I've been working on this over the last couple of weeks. The idea is that you can can start a session (click the number at the bottom and choose "independent"). Then other devices can subscribe to it (by entering the id as 'other').

I've built it for: * demos during talks * workshop/hack sessions

…seems to work okay so far, but I'd love to know what people think.

I saw Mariko give a talk about this last week - http://2016.render-conf.com/talks#drawing-on-canvas-a-few-th...

It was absolutely fantastic; really great information about image data & how to process it.

Re:Context Require - Load JS assets based on page content on Wednesday October 02, 2013 @01:56PM (#6484073)
Yeah, there is a bit of an overhead with that. Module server - https://github.com/google/module-server seems like quite a good solution. Though I'd agree, for a large number of sites it's far better to bundle them up.
Re:Context Require - Load JS assets based on page content on Wednesday October 02, 2013 @01:03PM (#6483701)
Ah, I've not had to deal with sharing between multiple elements yet - I'm kind of hoping that when I do require.js would give quite a solid base for it. YepNope seems like a good choice for this kind of thing, especially that it can bring in css assets too. Would be awesome to bring in all related assets for a element
Re:Context Require - Load JS assets based on page content on Wednesday October 02, 2013 @12:34PM (#6483507)
I wrote this post - feels like quite a simple approach. Would love to hear if anyone has done anything similar.
