I am working on https://baolib.org.

Applications on the public cloud raise strong concerns about data protection. As an architect, I spend a meaningful part of my time ensuring the security of customers’ data in the cloud.

Bao introduces an innovative approach where data remains on local devices while the cloud provides encrypted storage for synchronization and peer exchange. Because cloud providers cannot access the data, the need for due diligence is reduced.

Any feedback is welcome.

Any connection with bao or openbao, the fork of hashicorp vault ? I fail to see any reference on the site

icloudpd-rs - Fast iCloud Photos downloader, Rust alternative to icloudpd

The original Python icloudpd is looking for a new maintainer. I’ve been building a ground-up Rust replacement with parallel downloads, SQLite state tracking, and resumable transfers. 5x faster downloads in benchmarks, single binary, Docker and Homebrew ready.

I wrote this little web app over the weekend, the idea was to make you think about your next purchase by introducing a 48 hour countdown. In 48 hours you come back and decide if you really need this product, or if it was just an impulse buy.

All data lives in your browser (IndexDB) - https://buyitlater.vercel.app

I just add things to my Amazon wish list. I never buy anything from the list but it seems to put the idea out of my mind.

Nothing revolutionary, but there is a small organisation called The Himalayan Database [1] who have recorded (in great detail) climbing expeditions to peaks in the area. The data is available in a downloadable format, but it is a little awkward to browse. I have been working in collaboration with them to build a website for making the database more accessible https://himalayan-database.climbing-history.org/

I'm working on a TUI-based agent orchestrator called Tenex: https://github.com/Mockapapella/tenex

It's gone a long way to solve the "review" bottleneck people have been experiencing (though admittedly it doesn't fix all of it), and I'm in the process of adding support for Mac and Windows (WSL for now, native some other time).

Some of the features I've had for a while, like multi-project agent worktrees, have been added as a part of the Codex App, so it's good to see that this practice is proliferating because it makes it so much easier to manage the clusterf** that is managing 20+ agents at once without it.

I'm feeling the itch to have this working on mobile as well so I might prioritize that, and I'm planning to have a meta-agent that can talk to Tenex over some kind of API via tool calls so you can say things like "In project 2, spawn 5 agents, 2 codex, 2 claude, 1 kimi, use 5.2 and 5.4 for codex, use Opus for the claudes, and once kimi is finished launch 10 review agents on its code".

Cded an online universal bloom filter for all and for free. https://blooms-production.up.railway.app/

(not vibe coding, so ask me anything about bloom filters).

Recently built https://entrycast.com/ - there are other products kind of like it on the market already but I had some specific use cases I wanted personally, and decided rather than making it just for me, I'd for the first time in my life make it something others could buy too. No customers so far, but I don't really mind, to be honest!

You missed a perfectly good opportunity to explain your product :)

Two things I've been building this year, both trying to solve real problems I care about:

https://talonwatch.com : I kept seeing founders discover their Stripe keys were public or their database was wide open, usually after the damage was done. Built a passive security scanner for vibe-coded apps so that's easier to catch early. Free surface scan, no account needed.

https://thetracejournal.com : A small iOS journal that pairs a song with each entry. Music is tied to memory in a way nothing else is, and I wanted a place to capture that.

I'm currently working on https://FaunaMap.app (web/Android/iOS) which lets nature enthusiasts see which birds, mammals, reptiles, etc. can be expected at any location worldwide using the past 20 years of GBIF observation data. It features an interactive global sightings map, color-coded to quickly spot recent rarities nearby. Public birding hides from OSM and a hotspots heatmap are included for trip planning. Users can quickly log large numbers of observations in the field. Observations with images appear in an Instagram-like feed for interaction with other users. Personal species life lists (global, per country, and custom locations) are also included. Feedback is very welcome :)

Native macOS sandbox terminal:

- UI for sandbox-exec to protect filesystem - Network sandbox per domain - Secrets filter via gitleaks - Vertical tabs option

It's highly customizable. You generate native macOS app wrappers for each terminal app, each with its own rules and customizations.

I've been using a VM for claude code (probably would keep doing that as I do like how much control I have over it by doing that) but this is definitely a useful tool, I'll happily use that in the future.
