A good developer reference hub is not a pile of disconnected cheat sheets. It is a workbench: a place where you identify the task, copy a reliable pattern, and move directly into execution without breaking flow. That is the purpose of this page. It brings together compact references for shell work, editors, structured data, regular expressions, and relational databases so you can stay task-first instead of tab-first.
This hub is useful when you do not need a full tutorial and you do not want to hunt through vendor documentation just to remember a command flag, a syntax rule, or a keyboard shortcut. The pages linked here are written to answer practical questions fast: how to inspect files in Linux, how to recover safely in Git, how to structure JSON and YAML correctly, how to search with regex, and how to move faster in editors like Vim and Visual Studio Code.
These pages cover the commands that hold day-to-day development together. Use the Bash reference for shell commands and pipelines when you need variables, loops, redirects, or one-liners. Use the Linux command reference for system inspection and admin tasks when you need to check files, processes, disk usage, or permissions. Use the Git reference for recovery, diffs, and history review when you need a safe command path instead of guessing your next checkout, restore, or reflog move.
This cluster is usually step one in a real workflow. You inspect a file tree, pull the right file into your editor, and then compare, commit, or recover changes. Keeping these references side by side makes that sequence faster.
Editor speed compounds over time. The Vim reference for modal editing moves helps with navigation, text objects, registers, and repeatable edits. The VS Code shortcut reference for editing and code navigation focuses on the commands developers reach for most often: command palette, symbol lookup, commenting, multi-cursor editing, and go-to-reference workflows.
When your task turns into pattern matching, switch to the regex reference for capture groups, anchors, and quantifiers. Regex is the bridge between editor work and data cleanup, especially when you need to rename, validate, or extract values consistently across files.
Configuration and data tasks usually split into two layers: document structure and query logic. Use the JSON reference for strict data structures and schema-style patterns when you need valid nesting, arrays, escaping, or $ref awareness. Use the YAML reference for anchors, lists, mappings, and config syntax when the target is a CI file, deployment manifest, or human-edited configuration.
For relational tasks, use the MySQL reference for practical SQL snippets and the Postgres reference for psql and PostgreSQL workflows. These references are designed for the everyday tasks that matter most: listing tables, describing schemas, writing joins, checking constraints, and understanding REFERENCES or foreign-key behavior without reopening a full manual.
| Task | Best page to start with | What it helps you do quickly |
|---|---|---|
| Inspect files, pipes, and redirects | Bash Reference | Build one-liners, loops, and shell pipelines |
| Check permissions, disk, processes, or logs | Linux Command Reference | Inspect a machine or container without context switching |
| Review commits or undo safely | Git Reference | Compare history and recover from mistakes |
| Match or extract text | Regex Reference | Build search patterns and capture groups |
| Validate structured payloads | JSON Reference | Keep objects and arrays valid and consistent |
| Write config files | YAML Reference | Use indentation, anchors, and mappings correctly |
| Query relational data in MySQL | MySQL Reference | Work faster with SQL snippets and table inspection |
| Query relational data in PostgreSQL | Postgres Reference | Mix SQL with psql meta-commands efficiently |
| Edit fast in modal workflows | Vim Reference | Navigate and transform text without leaving the keyboard |
| Navigate codebases with shortcuts | VS Code Shortcut Reference | Find symbols, references, and editing commands quickly |
Generic search results are useful when you need breadth, but they are often noisy when you need action. A reference hub should reduce branching, not increase it. That is why this collection is organized around repeated developer jobs rather than around vendor marketing language or broad product categories.
You might also come here after searching for phrases like developer reference hub github, Red Hat Developer Hub documentation, or even Meta Quest Developer Hub download. Those searches point to a different problem space: platform portals, product ecosystems, and official API centers. This page serves a narrower and more practical need. It is not a replacement for a vendor's developer hub. It is the fast layer you use between “I know what I am doing” and “I need the exact syntax again.”
A useful developer reference hub contains short, dependable materials that support repeated tasks: commands, syntax patterns, keyboard shortcuts, schema examples, and links to closely related tools. It should help you answer “what is the exact form of this command?” or “which reference do I open for this job?” in seconds.
Vendor documentation explains a platform, API, or product surface in depth. A reference hub like this one is lighter and more tactical. It helps you move through everyday work: shell commands, editor motions, regex patterns, and SQL structure. You use it when you already understand the goal and mainly need the precise syntax or the right starting point.
Because repeated tasks benefit from stable, predictable examples. Search engines and forums are good for edge cases, but they add noise when you only need a working command, a quick reminder, or a safe recovery path. A curated hub reduces that friction.
Switch as soon as you move from remembering syntax to transforming real data. After reading the reference, open the relevant utility or adjacent reference to validate JSON, inspect regex behavior, compare SQL variants, or continue the workflow with the right tool.
Use this hub as the landing point, not the destination. Open the reference that matches your current task, copy the smallest working example, and then continue into the part of the workflow that produces an actual result. That is what makes a developer workbench useful: less browsing, more shipping.
