Ask HN: What are you working on? (January 2026)

I've been working on a polyfill for the new Navigation API: https://github.com/kcrwfrd/navigation-ponyfill

I've been super hyped about it. My main goal at first was supporting `navigation.canGoBack` and the `currententrychange` event simply so that I could implement perfect back buttons with (almost) zero edge cases. This is surprisingly very tricky with the older History API.

Today I just opened a PR with support for `entries()` and `currentEntry`: https://github.com/kcrwfrd/navigation-ponyfill/pull/33

Once that lands I'll be able to start thinking about implementing full-blown navigations with it, with cool stuff like navigation interceptors and whatnot. That would actually enable framework router implementations wholly based off the Navigation API, rather than simply patching some enhanced capabilities for use with a router based on history.pushState / history.replaceState.

I'm building a new AI-powered email client called Fluxmail: https://fluxmail.ai

Here is the current list of features:

- Unified inbox: Connect multiple Gmail accounts and see all your emails in one inbox. No more switching between different tabs or accounts.

- Email bundles: Automatically group your emails together into bundles, so if you have many emails from the same sender, they'll no longer clutter up your inbox.

- Email summarization: Save time by getting summaries of your email threads.

- Keyboard shortcuts: Navigate through your inbox using Gmail-style keyboard shortcuts.

- Automatic dark mode: All your emails are converted to dark mode automatically.

- Block email trackers: We detect and block email trackers to protect your privacy.

- Privacy-first: We sync your emails from Gmail and cache them locally on your device - they are not stored on our servers. We don't train on your data or use AI providers that train on your data.

Lots of other features coming soon, like split inbox, AI search, etc. It's in early access now, would love feedback from anyone interested in checking it out!

I'm also curious to hear - what is the most annoying thing about email that you have to deal with today?

Adding Julia language support to Godot. Delayed by a failed power supply, but starting back at it. Debugging has been a challenge since the native godot application is calling the julia shared object and I haven't figured out how to get the julia debugger to catch exceptions.

Cool! Is it Mac specific or could Linux be used as well?

Thanks! :)
