Show HN: BAREmail ʕ·ᴥ·ʔ – minimalist Gmail client for bad WiFi

2026-04-08 @ 14:44:23Points: 36Comments: 28

These clients have become pretty bloated with the assumption you've always got great bandwidth.

So I vibe coded BAREMAIL. It's open source, has no backend, and you can just set it up for yourself. Takes ~3 mins to setup API access via Google Cloud Platform (thanks for making this not super easy Google!)

I tried to maintain nice design and some important keyboard shortcuts without getting to overBEARing.

Show HN: I built a navigation app that displays weather along the route

2026-04-06 @ 13:58:58Points: 19Comments: 12

I live in northern part of USA where winters are snowy. Whenever I took long trips, I always wondered what the weather along the route is going to be. For those who live in northern USA, you know weather can change frequently, so when you're traveling matters a lot, not just the route.

To solve this problem for myself, I built https://navimodo.com/. NaviModo calculates the route, and then checks weather along the route based on your start time, and displays weather along the route. Change start time, and the whole thing is recalculated.

I am not expecting any commercialization for this, just wanted to scratch an itch, and just did it. I have ideas for adding additional features (suggestions for when to take breaks based on bad weather, auto-suggestion of start time to avoid bad weather, etc.,) but will add more as time goes by.

Any feedback is welcome!

In 2022 I was toying around with OpenAI's RL Gym, right when the first non-instruct GPT3 model came out. I was thinking about getting into ML a lot more, but hesitated. Before that it was 3D printers, mechanical keyboards, drones, etc. All of these have exploded, and while they are still very interesting, I do love my Browns and manage Prusas for my local hackerspace, they have just, for the lack of a better term, industrialized. I'm also now in a position where I have time and money for it, not like when I was 15 and rating Ender motherboard upgrades I knew I'd never buy.

Right now I'm making a chess engine, but that's already a solved problem. There's also biohacking, and while designing chips to go into my body is really interesting, I only have one, and don't want to push it too far. One promising idea is a kind of 'Personal Computer 2', where people try to innovate HCI, and while I really like that and do have some research ideas, I'd like to explore a bit more before delving deep into it.
