You don't even need to do this much, you can just invoke the function and let the return type be inferred. const inferred = (() => "Hello")() // Inferred as "string" If you really don't wan

Can any physicist explain the term "quantum metric"? Googling it appears to give no relevant results. Might it be a typo? > "The researchers said that the unique voltage arises from the electronic properties of the man

Circle is the "C++ Successor" language I am most excited about, after writing a fair amount of D, and trying the Carbon interpreter. The issue with D is that while it's a great language, and it has C++ interop, it doesn'

You use pragmas to disable/enable features on a file-by-file basis. Since existing code contains no Circle pragmas, it's compiled by the Circle compiler as "standard" C++. I urge you to try it -- there's binaries an

The Java code is impressively written, using newer features like MemorySegment. Looked at the author and realized it's Alfonso from the Graal team -- makes sense. I wonder whether the "matmul" code could be further optimized

FWIW, I prefer the taste of Coke Zero and Pepsi Max to regular Coke/Pepsi. My wife had never tried Coke Zero before we met and she also prefers it now. Not sure what they use in these alternatives but Diet Coke/Pepsi taste pretty

One of the most surprising things I learned about "clang" was how relatively poor the "libClang" capabilities are. I wanted to write a codegen tool that would auto-generate bindings for C++ code, and it turns out that &q

Do it yourself in ~20 lines of code with LlamaIndex. You give it a directory containing documents and ask it to build an index and vector data embeddings over the documents Then you can use this index with models like ChatGPT Tutorial here

Fantastic post, I appreciated that the ASM was displayed in tabs as both "standard" and "visual-arrows"-annotated. Kept me reading into the follow-up article. Also, I love the UI of this blog.

I own the book and would agree -- only reason I didn't suggest this is that the areas on query-planning and optimization are a bit thin. IMO it's great if you want a holistic view of building a query engine start-to-finish with ju

Well, I eat my shorts. Isn't LMBD closer to an embedded key-value store than an RDBMS, though? Also there's a section in the paper that mentions it's single-writer.

"mmap" in the general case is incredibly useful. There's so much you get "for free" and the UX/DX of reads/writes to it, especially if you're primarily operating on structs instead of raw byte/st

Out of curiosity, how many databases have you written? This is co-authored by Pavlo, Viktor Leiss, with feedback from Neumann. I'm sorry, but if someone on the internet claims to know better than those 3, you're going to need some
