How to Achieve Synchronization Across Multiple RAFT Groups

Achieving synchronization across multiple RAFT groups, especially for operations that span different partitions and require atomicity, is a complex but critical aspect of building scalable, consistent distributed systems. Below, we revisit the challenges and strategies for atomic operations across RAFT groups.

In a multi-RAFT architecture, each RAFT group independently manages a subset of data. While this design enhances scalability and fault tolerance, it complicates operations that must be performed atomically across multiple partitions.

Understanding Network Interfaces and Virtual Networking Concepts on Linux and macOS

In modern operating systems, networking is not limited to physical Ethernet interfaces (eth0, en0, etc.). There are a variety of virtual networking abstractions and constructs—like tun, tap, bridge, veth, subnet—that enable everything from virtual machines and containers to VPNs and complex local network simulations.

This document will break down how these components work, why they exist, and how they fit together. Examples will focus on Linux and macOS, with key differences noted.

Flutter Notes

Flex (Columns & Rows)

When you have a Flex widget, where the child with the maximum cross-axis size determines the cross-axis size of the rest.

If you try to use CrossAxisAlignment.stretch with a Flex whose parent is unbounded along the cross-axis, you will get an error.

To solve this, you should use Intrinsic* widgets. They do speculative pass on the Flex widget tree to determine the max size along the cross-axis and that becomes the constraint they pass to the Flex.

I'm trying t skip some fields with rkyv but I have managed to get it working yet. Frankly I don't want to think too much about it right now so I will be temporarily using bincode. I still believe in rkyv but it may not be ready yet for my use-case. I will keep it in my backlog to reimplement ser-de in rkyv.
