    GAM

    GAM

    Command line management for Google Workspace

    ...G Suite Legacy Free Edition has limited API support and not all GAM commands work. While many GAM functions do not require domain administrative privileges, the setup does. Download GAM, then run the MSI installer. By default, GAM will install to C:\GAM but you can change this to wherever you prefer. GAM will also be added to your path so you can run GAM even if you're not in the GAM folder. At the end of the MSI install process, GAM will open a command prompt to allow you to setup a project and authorize GAM for admin management and user data/config access.

    Git GUI Client

    Many Git client apps have some problems. It's too late to start up, falls well, is user registration tedious when downloading, is paid for commercial use, is not multi-platform, or is an animation or visual effect. It was said that the production was overkill and the wizard and the source code were not published. I tried to eliminate such inconvenience as much as possible. At first I started developing it for my own study, because I was interested in learning how to use Git and how it worked...

    Wuffs

    Wuffs

    Wrangling Untrusted File Formats Safely

    Wuffs is a memory-safe, zero-dependency library and domain-specific language for writing high-performance image codecs and related parsers. Instead of trusting ad-hoc C, Wuffs code is compiled to C with strong bounds, integer, and state checks inserted by construction, aiming to eliminate whole classes of security bugs without a heavy runtime. The design prioritizes predictable performance: decoders avoid dynamic allocation by default, return explicit “short read” signals, and run well in streaming or sandbox-free environments. ...

    Fluent migrations framework for .NET

    ...Migrations solve the problem of evolving a database schema for multiple databases (for example, the developer's local database, the test database and the production database). Database schema changes are described in classes written in C# that can be checked into a version control system. FluentMigrator is a .NET library that helps to version database schema using incremental migrations which are described in C#. The basic idea of the FAKE helper is to run FluentMigrator over the existing database using compiled assembly with migrations.
