I'm building an interactive map based search interface for concerts and events in the bay area: http://fanflame.city/

This is something I've always wanted for myself so I decided to build it. Plenty of event aggregators out there, but not many that let you search and filter by any combination of locations, dates, and genres.

It currently supports automated data feeds from ticketmaster and the Civic Joy Fund; hoping to add Parks & Rec, Library events, and some other ticketing sites in the near future.

It has been a fun way to keep my coding skills sharp (Eng Director by day), I've learned a ton about react, mapbox, django, postgis, and GCP doing it. If you have an event source I should look into or a feature request let me know!

I’m working on a free and open-source invoice generator with live PDF preview — fully browser-based, no sign-in required.

It supports multiple languages, currencies, European VAT deductions, and more.

I built this tool for myself so it’s kinda like a personal software. Hopefully, others will find it useful too :)

I'm working on a little 2D action puzzle game in Go on top of SDL (with bindings via https://github.com/veandco/go-sdl2). The prompt I've given myself is "Chip's Challenge meets Hotline Miami," but who knows how much of either of those elements will remain after I keep evolving the capabilities and general feel of the gameplay. For dev graphics I'm just cobbling together sprites from various pixel-arty asset packs I've purchased on itch.io, but in the future if I want to commercialize it I'll probably want to work with an artist to develop a unified look-and-feel for the game--I may even switch to 3D/2.5D depending on how the tone and my workflow evolve.

I've experimented with Unity, Godot, and GameMaker in the past, but for the time being I'd like to see what I can accomplish on my own in Go to keep my dev chops sharp especially since I've moved into an engineering management role at my job (which has nothing to do with game dev but is increasingly employing more Go source throughout). Something I've realized as I've been applying good code organization and reusability is that I'm essentially building an engine for anything top-down (hesitant to say "isometric" since I know that means something graphically specific)--RTS/TBS/tactics/RPG all seem doable with what I've built given a little bit of extra logic on top for each.

I’m working on Popgot ( https://popgot.com ), a tool that tracks unit prices (cost per ounce, sheet, pound) across Costco, Walmart, Target, and Amazon. It normalizes confusing listings (“family size”, “mega pack”, etc.) to surface the actual cheapest option for daily essentials. On top of that, it uses a lightweight AI model to read product descriptions and filter based on things like ingredients (e.g., flagging pean…

I don't think I have the time to go to different stores to buy different things based on what is cheap. I have one fixed one.

However, what I would like is a product where I upload my shopping receipt for a few weeks/months from the one store I go to. The application figures out what I typically buy and then compares the 4-5 big stores and tells me which one I should go to for least price.

I have been working on http://phrasing.app - a language learning & acquisition tool for polyglots. I’ve been using it to study ~12 languages (5 on maintaince, 2 seriously studying, 5 casually “studying”) and it’s starting to feel really good. If anyone is learning/maintaining several languages, please reach out! I’m looking for beta testers in as many languages as possible (it supports 120+). In what I believe is sti…

As someone who is both an avid language learner and a software developer - what’s the value added in this platform, for someone who is already pretty comfortable as a programmer and autodidact?

It would take a lot to convince me to pay that much for a product like this. True, it can be inconvenient trolling around for content in your target language, but as a software dev I am pretty experienced with finding obscure things on the internet by finessing search queries. And there are plenty of other apps out there that do spaced repetition for you, and open source tools and data sets that can be used to help you scrape/process vocab (again, if you don’t mind spending some time debugging, which I personally do not). Besides that, I really don’t find it that inconvenient to manually write down words/phrases from books or movies and copy them into my SR deck. On the contrary, I think this overhead actually helps the phrases stick better!

So how would you sell your site to someone in my situation? What would I get out of it?

I recently found out my wife wants a gecko, so I’ve begun planning for a mega-paradise. I want weather systems, every sensor I could possibly ram in there, cameras, and more. Planning to jury rig a toilet setup to run water from the reservoir to the rain system.

The gecko comes from New Caledonia, so my goal will be to replicate that environment as closely as possible. This will be difficult, since most of the plants on the island are only found there, but you can get surprisingly close.

One awesome fact I learned about this: conifers actually started out in warm climates. They just got out-competed once angiosperms (flowers!) came about.
