Resolving "protoc-gen-go: program not found or is not executable" Error in Go gRPC
While attempting to generate Go code for a gRPC application, you may encounter the error "protoc-gen-go: program not found or is not executable." This issue can arise due to using an outdated approach in Go 1.17 and later versions.
Solution for Go 1.17
In Go 1.17, installing executables using go get has been deprecated in favor of go install. To resolve this error for Go 1.17 and later versions, follow these steps:
-
Update your .bashrc or .zshrc file:
export GOPATH=$HOME/go export PATH=$PATH:$GOPATH/bin
-
Install the protoc-gen-go and protoc-gen-go-grpc plugins:
go install google.golang.org/protobuf/cmd/protoc-gen-go@latest go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
This will download and install the latest versions of the necessary plugins.
-
Generate the Go code:
protoc --go-grpc_out=. *.proto
This will generate the Go code needed for your gRPC application.
Additional Notes:
- Ensure you have the protoc compiler installed and available in your PATH.
- Restart your terminal or command line after making changes to your .bashrc or .zshrc file.
- Consult the official Go documentation for the most up-to-date information on installing and using these plugins.

Learn Go String Manipulation: Working with the 'strings' PackageMay 09, 2025 am 12:07 AMGo's "strings" package provides rich features to make string operation efficient and simple. 1) Use strings.Contains() to check substrings. 2) strings.Split() can be used to parse data, but it should be used with caution to avoid performance problems. 3) strings.Join() is suitable for formatting strings, but for small datasets, looping = is more efficient. 4) For large strings, it is more efficient to build strings using strings.Builder.
Go: String Manipulation with the Standard 'strings' PackageMay 09, 2025 am 12:07 AMGo uses the "strings" package for string operations. 1) Use strings.Join function to splice strings. 2) Use the strings.Contains function to find substrings. 3) Use the strings.Replace function to replace strings. These functions are efficient and easy to use and are suitable for various string processing tasks.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
