* docs: fix grammar mistakes in markdown files Correct `its`/`it's`, verb-noun agreement, article and number agreement errors in V-owned documentation. vlib/x/encoding/asn1/DOCS.md: fix the bulk of the issues, including `Its` -> `It`/`It is`/`This is`, `two form` -> `two forms`, `four class` -> `four classes`, `a extra` -> `extra`, and `you hope an universal type` -> `you need a universal type`. Other files: single-grammar fixes in chacha20poly1305, ttf, net/jsonrpc, vpbgen, bench/vectors and examples/templates READMEs. Vendored thirdparty/ files and historical changelog entries are left untouched, since the former are external code and the latter are verbatim commit records. No behavior change. `./v check-md` passes on all changed files. * fix review feedback --------- Co-authored-by: qp <168933756+gabytz777@users.noreply.github.com>
Comparing C# and V Boids Algorithm Implementations
Running the C# program:
dotnet run
Creating a release version of the C# program:
dotnet publish -c Release -r ubuntu.20.04-x64
The generated executable will be in
/v/vnew/bench/vectors/bin/Release/net7.0/ubuntu.20.04-x64/publish/vectors
Its size is ~64MB. After stripping, the executable shrinks to just 11MB,
but unfortunately it also stops running after stripping :-| .
Compiling and running the V program:
v crun vectors.v
... produces and runs a vectors executable which is ~1.3MB in size.
Compiling and running the V program, compiled with -prod:
v -prod crun vectors.v
... produces and runs a vectors executable which is ~176KB in size.
After stripping, the executable shrinks to 157KB. It can still run after
stripping.
Note: using crun will make sure that the compilation will happen just
once at the start, and then the executable will be just reused by the
subsequent commands with identical options. It will also ensure that
the compiled executable will not be removed, unlike run .
