#192I'm working on a focus / pomodoro timer again that I started a few years ago.
The redeeming qualities, are that it doesn't require login, and you can just use it as a simple pomodoro timer that syncs to youtube / spotify music.
The additional features are all optional. Configuration, timeblocking, task management, etc... The features that are paid are just 1 (relatively low) price (with PPP per country). No subscriptions.
I started this project after pomofocus added giant ad banners, and had been missing some quirky things I had always wanted in a timer.

So instead of people using the right tool for the right job and learning single table design when using DDB, they are going to use the completely wrong tool. I can just imagine the sub optimal in memory aggregations and expensive use of read and write units.
Valid points. The read cost and in-memory aggregation concerns are real and worth flagging. DynamoSQL is index-aware and will use your partition keys, sort keys, and GSIs where it can, but you're right that a well-designed native access pattern will be cheaper. That said, not everyone using DynamoDB has the luxury of designing perfect access patterns from the start. Real production tables are often messier than the t…
For analytical are exploratory work, it still would be much more sensible to use DynamoDB streams with a simple Lambda and write it to an Aurora Serverless Postgres/MySQL table.
The tradeoff of doing aggregations and joins in memory just isn’t worth it.

#194I just built a Google Chrome chess extension. It is a new tab page full of chess puzzles. It has various difficulties, and a speed run game (solve as many puzzles as you can in 60 seconds). I personally think it's the coolest browser extension I have ever seen (being objective as possible).
It works on Chrome and Brave for now. Planning a Firefox release soon.
If you're a chess fan, you'll probably love it, but if not, let me know why (I'll try to improve it).

I agree for cases that need real-time replication and are querying at high frequency. There is a trade-off, though. You're adding three services to maintain, there's replication lag, and Aurora's running continuously whether you're querying or not. For teams that need occasional analytical access to their DynamoDB data without building and operating a replication pipeline, I still think the in-memory trade-off is worth it. Different teams, different trade-offs.

#198https://GetCozyCritter.com
It's an ESP32 board used as sleep trainer for children.
Uses colors, images, and arcs to help them understand what time it is.
Full prototype is done but waiting for 3d printed enclosures.

#199I'm building my own cloud (I actually typed claude instead of cloud there... wow). There's no IaaS or PaaS; it's much simpler. I wanted my own way of connecting to machines and the TCP services on those machines without having to install Tailscale (not allowed on a locked-down corporate PC) or pay for Azure or AWS or GCP or even Hetzner or Linode. I've got 10gbps fibre and a huge workstation at home, and I've got lot…
You are rebuilding tailscale but requiring a centralised hub. I did the same in 2016 (pre-tailscale?) https://web.archive.org/web/20160304013451/https://wormhole....
I am not sure WireGuard existed at the time, and I used SoftEther and based it all on doing outbound tunnels to TCP/443* to avoid firewall blocks in corporate networks.
You could explore full P2P by leveraging UDP hole punching: https://cloudnetworking.pro/firewall-bypass-series-1-2/ https://cloudnetworking.pro/firewall-bypass-encapsulating-tr...
(WireGuard may already do it, dunno)
Also, fun fact, tela is also Spanish for fabric. Given the Filipino history, I guess it comes from there.

#200I'm building a YouTube for recipes. Basically it is YouTube clone, but improved to follow the actual recipe (ingredients, steps, etc.) Was frustrated with discovering and following online recipes (blogs are fludded with SEO content, YouTube is not optimized for recipes). So I gave it a try to build something I wanted. https://www.cookcook.it
I like this but your hosting is also through YouTube?
