I am working on Baduk Teacher, which makes having Go lessons (the board game) across different languages possible. The highest level of human Go is predominantly in Korea, China, Japan and Taiwan. Western world is catching up, but the gap is still very huge.

I think the main reason is that the West has quite limited access to pro-level teachers (similar to how chess is like in Asia, just the other way round). Most pro-level Go teachers in Asia do not speak/read any foreign languages (e.g. English), so I want to remove the language barrier and make high level of Go teaching more accessible to the Western world (so that the Go population there will increase). Several European users used it and the feedback was good (and recurring purchases). The translation part is working quite well (Go-specific domain translation), and I hope it will help more foreign Go enthusiasts improve their game.

Have been working on a modern replacement for Notational Velocity (last updated in 2011), I call it “neonv”. https://github.com/msnodderly/neonv

When I was working at amazon (left May 8) working on agents was all the rage. Combined with initiatives that set goals for nearly all services to have a MCP built and available by the end of the year agents will be even more emphasized in the future.

However what happens when you actually build and launch your agent is customers try it, do some initial runs and then go ask your manager to automate their use case. That is why I have been building https://toolscaled.com/ The goal being work through your problem space using agentic chat (like Claude Desktop) and then at the end convert it to a workflow. I am pretty close to launching and have been testing. If you're interested send me an email! (if you do sign up just fyi its still in beta so YMMV.

Interesting to hear that Amazon is doubling down on mcp

I’m working on a web app called Pitch coach. It has vocal exercises and shows you in real time whether you are flat or sharp. Everything is saved in browser so there’s no account creation. Coolest part is that you can upload a song and it will split the vocals, recognize all the vocal pitches and then you can sing along. Crazy how much you can do in the browser these days! https://pitch-coach.pages.dev

I had a good laugh, I can't sing. Stuck on Get ready. Was there something that was supposed to happen after that? Anyway, play/pause button is too high up, I was looking for it at the bottom of the screen. I like the UI.

This is very fun. Having just tried it with my maybe tone deaf partner, she showed progress when she sang at the same time as the notes. It might be good if there was like a faster looped version where the notes would play more frequently.

In the current climate, I've decided to explore building games, so I'm building a management game about turning chaotic fields of research into fundable products, fitting for Hacker News I think ;)

The concept was, what if Theme Hospital was about Victorian-esq research institution instead of a hospital? You hire strange scientists, have them explore dangerous fields of research, collect messy findings, turn them into theories, prototypes and eventually products, all the while trying to convince investors they're worth funding before they hit the market and work out what they might actually be worth

The gameloop is broken down into two parts, Exploration / Discovery and Exhibition, the closest comparison I have for the first part is take Kerbal Space Program, but focus it on Mission Control rather than the astronauts

While the mad scientists are going into weird, unstable research domains, the player is managing the institution around them, funding, equipment, research direction, safety

On the other side as you discover interesting things or successfully develop prototypes worth showing off, have investors show up and see what excites them, will they give you more funding? Push a grant your way? How are you going to keep this circus going?

You're balancing two plates, you need to invent tools to delve deeper and if you don't keep finding exciting new discoveries, your investors will slowly get bored of you

I have been going regularly to the Edinburgh Festival Fringe and their app is always terrible. Connectivity is very spotty since the city is swarmed with way more people than usual and the older buildings can kill your signal.

So I've been working on https://fringeflypost.com/, an event tracker with maps, search and filter, scheduling, and sharing with friends that's offline first. It syncs down a locally stored sqlite database and caches assets pretty aggressively.

(You don't actually need to sign up, and you can just jump into the list of shows directly here https://fringeflypost.com/shows).

Looks excellent and the offline caching likely very useful for those in a rush when they turn up at the wrong venue and need to hot foot it elsewhere. Any chance of some attribution on the map?

Working on my version of Dynamicland. Today I got this small thing working where I can now live-edit the behaviour of the editor script, see https://www.youtube.com/shorts/ZjxPIv-XwoU

Repo is here if anyone wants to have a look: https://github.com/deosjr/unreal-talk

And a browser-based version can be found here: https://deosjr.github.io/dynamicland/live

I'm working on a proposal for C++29 to extend `std::execution` by introducing a type-erased sender (P4223 https://wg21.link/p4223).

I discovered this week, while the paper was being reviewed by SG1, that I've accidentally stumbled into tackling a rather important problem. Senders as shipped in C++26 can really only express the async equivalent of inline functions because, except for `task`, all the standard senders fully encode the shape of their computation in their type. With something like the `function` I'm proposing, you can use senders to express async algorithms that are separately compiled, just like sync functions.

If the feature lands in a shape similar to what I've proposed in P4223R0, then I think an obvious extension is to modify the core language to support a newer kind of "coroutine" that allows you to define a sender with imperative code. My vision here is that we act on the observation that `std::execution` is a language feature implemented in the library by teaching the compiler how to turn imperative C++ with `co_await`s sprinkled through it into the corresponding sender and operation state. I think this would open the door to putting async object lifetime analysis and optimization where it belongs (in the compiler) without the overheads and inconveniences of C++20 coroutines. It would even let us apply the inliner to async functions when the compiler can see the body of an async callee, not just its declaration.

For now, my next step is to write P4223R1 to incorporate feedback from this past week's WG21 meeting, and continue exploring the design space around specifying sender attributes for a `function`—I'm thinking the current approach of specifying query function signatures needs to be replaced with a key-value object like receiver environments, but I'm not sure yet what consequences that change would have on the design.

Building a universal humanoid controller app for our Booster K1 robot. The native app, apparently, leaves much to be desired.
