+## Port Joeson from coffeescript to golang
+
+Worked on this from june 2022 until january 2023. Bounty [applied for](https://github.com/gnolang/bounties-old/issues/33) on Feb 2, 2023.
+
+    4. Port JOESON to Go
+    github.com/jaekwon/joescript
+    The intent is to create an independent left-recursive PEG parser for Gno.
+    Optional: port Joescript or Javascript.
+    1000 ATOMs from @jaekwon
+    More GNOTs than from #3.
+
+ The [port is here](https://github.com/grepsuzette/joeson/).
+
+## GNO grammar - partial
+
+In summer 2023, started to port the GNO grammar using Joeson. Grammar was posted in [PR 1156](https://github.com/gnolang/gno/pull/1156). There are only 3 files (in `gnovm/pkg/gnolang`), they are quite dense though:
+
+1. [joeson_test.go](https://github.com/grepsuzette/gno/blob/joeson/gnovm/pkg/gnolang/joeson_test.go)
+2. [joeson_rules.go](https://github.com/grepsuzette/gno/blob/joeson/gnovm/pkg/gnolang/joeson_rules.go)
+3. [joeson_f.go](https://github.com/grepsuzette/gno/blob/joeson/gnovm/pkg/gnolang/joeson_f.go)
+
+## gnAsteroid
+
+gnAsteroid is an asteroid creation-kit, it was started, merely for myself, around the time came publicly posting my joeson port. 
+
+Asteroids orbit gno.land, it's the same blockchain, but different frontend,
+themable, working with wiki-like markdown files (enabling realms from gno.land
+to be rendered there).

+
+## Research with markdown and gnoweb, mini-games, experiments (summer-oct 2024)
+
+Experiments including 2 games and **research with gnoweb, markdown, html, css, js-less**.
+
+* https://greps.gnasteroid.com/r/grepsuzette/pr2554/v6/games/tictactoe

+You can check [the page with all experiments here](https://greps.gnasteroid.com/conjects/gnoweb.md).
+
+## Tendermint vuln retrospective (2023)
+
+Also worked on an anthology of publicly knowned vulnerabilities that affected Tendermint. 
+
+* [Cosmos-sdk vulnerability retrospective](https://github.com/gnolang/gno/issues/587)
+* found most vulns were not affecting our Tendermint version, however:
+* [demonstrated vulnerability to BSC 2022-10-07 hack](https://github.com/gnolang/gno/pull/583)
+* [proposed fix to vuln to BSC 2022-10-07 hack (merged)](https://github.com/gnolang/gno/pull/584)
+* not all of them were tested, as I was hoping some more feedback before to continue.
+
+Thanks for reading!
