It mutates the existing value and yields it again (unless the toplevel value is a string, because strings are immutable in JS).

Yeah, another fun one is string enums. Could tread "DeleteIfEmpty" as "Delete".

Numbers, booleans, and nulls are atomic with jsonriver, you get them all at once only when they're complete. For my use case I wanted streaming parse of strings, I was rendering JSON produced by an LLM, for incrementally rendering a UI

If you send a task off to a work queue in another thread, and then do some local processing on it, you can't usually use a single Arena, unless the work queue itself is short lived.

I love spreadsheets for casual stuff, but my concerns with using them for anything heavy duty are twofold: change management and correctness testing. Other software that I use and write is version controlled and has tests to catch errors, m

Yeah, that's vanilla syntax. The semantics are fairly magic though. The component function that calls useState though isn't a normal function, it's a function that must be called in a special way by the React runtime in order

One thing to take care with in cases like this, it probably needs to handle code with syntax errors. It's not uncommon for developers to work with code that doesn't parse (e.g. while you're typing, to resolve merge conflicts,

A person might have mistyped a price, a barcode may have been misread, the unit prices might be correct but the quantity could be mistaken. Modeling uncertainty well isn't just about measurement error from sensors. I wonder what it&#x2

nix manages the environment too, all direnv is doing in my setup is automatically entering and leaving environments based on my current working directory. Looks like mise does that automatically, which is neat. mise looks nice, uses PATH ma

A flake.nix file plus a direnv `.envrc` file with `use flake` has solved this for me. When I cd into a project directory I get all of the tools that project needs, at the exact versions they were tested with. When I cd out of the directory,

Instead of using a dodgy package manager, install `nix` and use `nix run`. Get access to the largest collection of packages, and lean on a highly principled and secure baseline rather than… whatever this is. Easy to install on Mac, Linux, o

You're speaking out of ignorance here. Steam has a long-term relationship with its customers. They can and will remove a title from a user's library if the payment is charged back, as well as placing restrictions on the account.

Tricky thing there is that the VM would still need to do checks at all the boundary points, including all of the language-level and runtime-level APIs. At what point along such a migration would it become net faster? It'd need a ton of

Private fields, unique symbols, there's many ways to do nominal typing in TypeScript, depending on what you want.

The system described in the article is very React-like, and could be used by future versions of React. In both, functions return a description of HTML to render, which can be applied either to create new HTML or to update previously rendere

Yes, MCP adds no new fundamental capabilities. What it does is solve an N x M problem, where to hook up a given tool to a given LLM scaffold you have to write specific integration code for that combination of scaffold and tool. With MCP tha

Models are deterministic, they're a mathematical function from sequences of tokens to probability distributions over the next token. Then a system samples from that distribution, typically with randomness, and there are some optimizati

I agree with your general point, but C++ isn't a great example, as it is so underspecified. Imagine as part of our calculator we wrote the function: int add(int a, int b) { return a + b; } What is the result of add(3

Good question. jsonriver is well optimized, exhaustively tested (tens of thousands of test cases), and provides a number of potentially useful invariants[0] about its parsing. jsonriver's performance comes primarily from simplicity, an

Hm? They have 128GB of RAM. Macbook Pros cap out at 128GB as well. Will be interesting to see how a Project Digits machine performs in terms of inference speed.
