I've been working on a voxel game engine called Bonsai for ~10 years. Probably the most interesting thing about it at the moment is the editor. The world, and most things in it, are represented as collections of SDFs. More accurately, they're density fields, but, potato-tomato. Bonsai has undergone a large rewrite over the last couple years that's nearing completion. A world edit is defined as a bunch of SDF paramete…

SDFs are the future at least when it comes to level design - especially because they have that "subtract" railgun cone of death functionality baked in. A boss fight feels different, if where the hammer comes down there is a crater afterwards.

I'm working on a real-life social app called Holler ( https://justhollerapp.com ). I'm an introvert and socially anxious, but I do enjoy hanging out with my friends. I just HATE the invitation-and-coordination game. If someone invites me and I don't want to go, I hate having to come up with a socially acceptable excuse. Inviting someone and waiting for them to make a socially acceptable excuse is equally awful to me.…

Is this some kind of "actuallysocial-media"?

This sounds great! The main barrier I see is getting everyone I want to install the app. Perhaps a "mass-SMS" variant could work, so it's independent of whatever messaging apps everyone runs.

I've just released a lowkey hangout app called you coming on iOS and Android!

I moved to London and was drowning in tons of 500 person whatsapp group chats to make friends. It took way too much executive function just to go to a bar.

The way I think of it: chat apps like whatsapp and iMessage were designed around chatting. Facebook, Insta are designed around engagement with strangers, you coming is designed around hanging out.

How it works:

- add some friends, acquaintances, that person you met at that thing - throw out an idea, doesn't even need a time or place at first - or add something to your bucket list in your profile - people can opt-in, find a time if needed, or even pitch a plan everyone can vote on - chat only opens once the people-time-place is set, and self-destructs after the event - you can share events and collect RSVPs with people off-app, so not everyone needs to get it

I will start some curated events in London soon too (if you have events you'd like to see on there in your city, let's chat!)

Until then, check it out?

We have continued to build GhanaHousePlanner https://ghanahouseplanner.com and it is now a construction operating system built for Ghana. The platform currently has 7 entry points covering people starting from house idea to people with an existing house plan and those who are already building and only want to manage their build. We have had usage from local regions and also the diaspora. The team is currently focused on expanding user acquisition and helping users complete their house projects through bringing on board experts like supervisors, architects, tradesmen, land registration and material suppliers, example is Marani (a MEP expert). We are also expanding the French language support so that we can license the platform for usage in other countries in Africa.

If anyone else really loved that lovely GLSL fluid sim that's been posted here a bunch, I'm working on a beefed up version of that same shader: https://swirltogether.com/

I've added some playful collaborative parts, and I'm doing a playtest of it over the next few weeks before releasing it as a demo on steam at Next Fest.

I keep chipping away at my running app, RunCoach!

I've recently managed to bridge the biggest gap I've had and, while it seems to be something that is NOT yet great from a UI/UX perspective (you need an account with intervals.icu to use it), I can now send workouts with structured splits, pace targets and reps to my Garmin watch, which effectively means I can replace using a paid app with my own to get, essentially, the same benefits.

I did put a previous version to the test, by running a plan generated with it to run my first ever trail race in May (a 22Km race with over 1100m elevation successfully completed) and since then I've kept revamping plan adaptation, workout generation and watch integration and it's now sitting in a very sweet spot for me, I might actually cancel my paid app subscriptions after running a few more hundred kms to really test it! runcoach.fly.dev

I’ve been working on cafegrinds.com - a simple hyperlocal social app to invite people to work together. Networking has been a huge challenge being freelance, working remotely, and as an introvert - solving my own problem with this!

Events/meetups are either paid or recurring at a per month or above frequency. These are not enough to develop the same camaraderie you’d with a coworker that sits next to you.

In any type of coworking space, anecdotally, people rarely ever ask others about work BUT if somehow (charger, wifi password etc) conversation initiates, people enjoy talking about it. This is unfortunately rare and you will never really see the same person again.

The app does these things (at least) - It lets you meet other remote workers publicly in a work setting and gives you an opportunity to connect professionally (or personally) over and over - Three people max makes it much more intimate than meetups where conversations usually center around people that are very expressive.

Only in Bangalore for now and completely free!
