Scratch orgs vs sandboxes: what each one is a copy of
A scratch org is built from your repository and expires within 30 days, while a sandbox is a copy of production that you refresh on a schedule.
Or start from an error
Write-ups of the exceptions, limits and platform behaviour that come up when you build on Salesforce. Paste the exact error you got into the search box, or start with the newest articles below.

SINGLE_EMAIL_LIMIT_EXCEEDEDThe daily single email limit counts every recipient, including ones queued earlier in the same transaction, and you can test it without sending mail.
System.enqueueJob accepts a delay of up to 10 minutes, and a duplicate that AsyncOptions rejects still uses one of your 50 enqueues.
The six pieces that explain the platform behaviour every other article on this site assumes you already know.
Paste an exception into search, or pick it out of the list. Each one is explained by what actually triggers it.
Each email is a single new article. Unsubscribe in one click.
Record-triggered flows, scheduled paths, fault handling, and the errors Flow throws when it hits a limit. Flow behaviour changes between releases more than any other part of the platform, so check the date on an article before relying on it.
Apex, SOQL, governor limits, and the exception messages you land on when you cross one. Written for developers who need the cause and the fix, not a restatement of the developer guide.
Permission sets after profile retirement, sharing models, record types, and how to work out who changed what.
Large data volumes, ownership skew, sharing recalculation, and the design decisions that are expensive to reverse.
Named Credentials, External Services, Platform Events, Bulk API, and the integration failures that only show up at volume.
Agentforce agents, actions, prompt templates and grounding. The newest part of the platform and the least documented, so expect this section to be corrected often as it matures.
What actually changed in each Salesforce release, what has a deadline attached, and which of the headline features can safely wait.
Study guidance, experience reports, and career notes. No exam questions or dumps, ever.
