１．はじめに UTF-8 の文字コードのファイルには、BOM (Byte Order Mark) がある場合とない場合がある。 Unicode の規格では、BOM は、推奨されないが、許容されている。 ja.wikipedia.org 今回、必要があり、色々な OS や言語で、UTF-8 の文字コードのファイルを作成した時、BOM が記録されるか、されないか、を調べた。 ２．色々な OS や言語での BOM 2.1 Windows 10, Visual Studio, C++, _wfopen (_tfopen), // Visual Studio 2005 以降 保存 FILE *fp = _wfopen(name, _ L"w, ccs=UTF-8"); if (fp == NULL) { // エラー処理 } fwprintf_s(fp, L"ABC漢字123\n"); fclose
I'm concerned by the number of times I've heard, "oh, we can do RAG with retriever X, here's the vector search query." Yes, your retriever for a RAG flow should definitely support vector search, since that will let you find documents with similar semantics to a user's query, but vector search is not enough. Your retriever should support a full hybrid search, meaning that it can perform both a vect
A microcontroller Macintosh This all started from a conversation about the RP2040 MCU, and building a simple desktop/GUI for it. I’d made a comment along the lines of “or, just run some old OS”, and it got me thinking about the original Macintosh.
