Find: invested .Replace: invested and decided to sell at this very moment,not a day after,not a day before. (Because until you sell, you got 0). Volatility looks bad in comparisons like these. If you have a little bit of control over when to withdraw, you can just wait trough it.
Here is how much you would have if exactly one year ago you would have invested $1,000 in one of these:. - $1.040 if in a 1-year treasury bill (a treasury bond).- $1,010 if in Bitcoin.- $963 if in the S&P 500.- $616 if in Solana.- $424 if in ETH. Of course market is down right.

At 4.000, dotnet/fsharp is having only 5x less GH stars 🌟compared to dotnet/roslyn (thats for C# and vbnet combined) 🥳. Let’s keep adding more 👍🙂.

INSERT INTO event_store (event) VALUES(“{type:’transfer-attempt’, from:’A’, to:’B’, amount:100}”). You anyway need auditing and history📆. You still need to log unsuccessful attempt🏦. Event sourcing is a functional paradigm for data management. Make it part of your toolbox ⛑️.
Here's one way of performing a bank transfer in either Postgres or MySQL (it's slightly easier if just MySQL). It gets messy very fast if you need any complex logic, which is why business logic almost always ends up on the application server in a traditional stack, not the DB.

I always pronounced OOP by spelling it, O-O-P. But hearing Heljsberg call it /uːp/, like “oops” without the s - I do like that version a lot more :-)).

The guy writing compile-time Doom in TS must be full of joy today, imagine dropping compile times from 12 days to 1.2 days 😂.

This in the context of validations + language services for LLM output = imo well justified.

Seeing a compiler not bootstrap itself is a missed dogfooding opportunity. But with js runtime, the struggle of seeing how much perf was left on the table must have been real.
Thrilled to announce.

My least favorite forms of #fsharp code :. 3. SingleObject |> _.Member ( just use a plain dot in that case, god dammit!). 2. End of line "else", big block below not indented. 1. End of line "&&" in a bool-returning function, big block below not indented.

A very nice fusion of large language models and built-in F# evaluator for computational requests.
Experimental 'chat with code evaluator' feature added to FsOpenAI to generate and evaluate F# code interactively. (need own OpenAI key). Evaluation sandbox utilizes typed AST to only allow types from set namespaces.
