https://github.com/shish/rosettaboy The same gameboy emulator rewritten in C++, Go, Nim, PHP, Cython, Python, Rust, and Zig (and WIP typescript); mostly to teach myself the languages and to compare and contrast their idioms. Also, when taken with a very large grain of salt, usable as a language benchmark (As with all benchmarks, there are lots of caveats - but as far as I’m aware this is unique in being “the same cod…

Really cool! What were your impressions of all the languages you've implemented this in?

I created a browser extension to help transition to Mastodon[0]. If you are curious about Mastodon but don't yet feel like you can leave twitter.com then it's a great way to get started. Essentially it injects Mastodon posts into your Twitter timeline, so you can retain your existing Twitter following while getting exposed to Mastodon.

I'm working on a Firefox version right now as well.

It's not 100% done yet - the rough MVP functionality is in place - but I'd love to know what people think https://shielded.dev/ Simple API controlled README "shields". Lets you update a custom badge by API - fully open source. Lets you update the badges to say whatever you want as part of your CI process. For instance we have it show the number of build warnings the most recent build generated. Example badge: https:/…

Nice, but I'll be honest the page looks a bit drab to me. Could just be me, but I figure folks here would like feedback so I hope this helps. In general I think for a page that is promoting badges you need an appealing aesthetic.

I’m developing https://travelermap.net with my brother. It’s a map of National Parks all over the world and more detailed map with other kinds of parks in US.

We started adding photos and more content to US parks but planing to cover more countries.

Built with Elixir/Phoenix, Typescript and Maplibre.

I made (admittedly, the 200th) uptime monitoring service - https://onlineornot.com I've been running the business for almost two years now (and it's now more of a status page that also monitors uptime), and it's still steadily growing!

Interesting. How's the MRR if you don't mind sharing?

MapLibre board member here. Really cool map! I also just love seeing MapLibre random places on the internet. :)

It's a freemium subscription service to the algorithmic trading models / hedging systems I've been developing over the last few years. 2022 performance:

SPX (benchmark): -18.77%

Free models:

TA - Mean Reversion Basic (https://grizzlybulls.com/models/ta-mr-basic): -9.93%

TA - Trend Basic (https://grizzlybulls.com/models/ta-trend-basic): -17.79%

Vix Basic (https://grizzlybulls.com/models/vix-basic): -20.45%

Premium models:

Vix Advanced (https://grizzlybulls.com/models/vix-advanced): -17.9%

Vix - TA Advanced (https://grizzlybulls.com/models/vix-ta-advanced): -16.14%

Vix - TA Macro Advanced (https://grizzlybulls.com/models/vix-ta-macro-advanced): -3.15%

Vix - TA Macro Monetary Policy Extreme (https://grizzlybulls.com/models/vix-ta-macro-mp-extreme): +0.56%

The models use no leverage and are always either 100% long the S&P 500 or 0% long (in cash). These are not HFT, averaging one trade per 2-4 weeks on average depending on the model. You can see active signals for the free models by checking the site frequently, or if you subscribe to one of the premium plans you'll get email or text notifications as well.

In 2022, all but one of the models beat the SPX on an absolute performance basis, some substantially so with the top model returning positive absolute returns with a +19.33% outperformance gap. However, it was still a much worse year than 2021 as the unprecedented reversal of Fed policy in response to 40 year high inflation proved to make a challenging backdrop.

My take on the EMH, in short I believe in the 95% EMH, but that 5% makes all the difference and perfectly explains how legendary traders like RenTech, TwoSigma and David E Shaw have been able to outperform the market consistently for decades: https://grizzlybulls.com/blog/time-in-the-market-vs-timing-t...
