Napkin Math is a technical reference project for estimating software system performance from first principles. It collects practical numbers, benchmark-style measurements, and mental models that help engineers make fast back-of-the-envelope calculations. The project is useful for questions like how much memory throughput matters, how long storage operations may take, what network latency to expect, or how expensive logging could become at high request volume. It treats these values as rounded numbers for reasoning rather than exact performance guarantees. ...

Easily and securely share files and directories from the command line through a safe, private and encrypted link using a single simple command. Files are shared using the Send service and may be up to 1GB. Others are able to download these files with this tool, or through their web browser. All files are always encrypted on the client, and secrets are never shared with the remote host. An optional password may be specified, and a default file lifetime of 1 (up to 20) download or 24 hours is...

rallyup is a lightweight Wake-On-LAN (WOL) scheduler and dependency manager designed for small businesses and home labs. It ensures that infrastructure services like firewalls, storage, and hypervisors are brought online in the correct order, particularly after events like power outages. A typical setup involves configuring most of the infrastructure for WOL but not for Wake-On-Power, and setting rallyup to run on startup on a low-power device like a Raspberry Pi. When you need to bring the...

You list files hundreds of times a day. Why spend your time squinting at black and white text? exa is an improved file lister with more features and better defaults. It uses colours to distinguish file types and metadata. It knows about symlinks, extended attributes, and Git. And it’s small, fast, and just one single binary. Different types of file and data will be coloured differently, and the user and group columns will be highlighted for the current user. exa can display a file’s extended...
