Atomic refreshing in memory DBs without mutexes

This is a simple way of having an in-memory DB which is safe to use across multiple goroutines without needing to use any kind of mutex for updates.

1. Create an interface

type FooDB interface {

🚐 MINI BUS

Mini Bus is a drastically simplified version of D-BUS, specifically for plain text communication between terminal UIs / shell scripts and terminal multiplexers.

minibusd

Minibus daemon monitors /tmp/minibus for newly created UNIX Domain sockets (SOCK_STREAM) and connects to them based on their location:

This is a bard test file, everything here is run and evaluated.

Bard testing tool

Bard is a commandline utility for running code tests in multiple languages using Markdown files as the source. Bard has two basic concepts:

  1. Bard extracts code blocks from markdown and executes them with the native language test tools.
  2. Bard interleaves shell commands using a special syntax that compares command output with expected responses.

Atomic client side stores with server sync

At CampJS this week there were a lot of talks about frontend web components, mostly focused on views. It struck me, as a mostly backend engineer that we could do with some better abstractions around client side/server side data sync to go with the new view model systems out there. Here's a few thoughts I had over the weekend..

A client side, in memory data store:

  1. Which is atomic (transactional?)
  2. With data that is strongly typed (validated)
  3. That syncs to a server (which is authoritative)
  4. That syncs uncommitted content to local storage transparently
  5. That is resilient to connectivity trouble
  6. That is bounded by the developer

Anvil SQL helper

Anvil is a golang lib and wrapper for database/sql that aims to provide:

  • Out of the box CRUD operations for user defined struct types
  • Extensible operations via user defined SQL templates
  • A structured representation of Tag defined SQL field types for use in SQL templates
  • Helpers for working with multiple DB sharding
