What I got wrong, and when I fixed it.

Versions, prices and dates on this site go stale, and sometimes I am simply wrong. When a post changes after it is published, the change is recorded here and at the foot of the post.

How it works

• A correction fixes something that was wrong when it was written. An update adds something that changed afterwards.
• The post shows an "Updated" date under its title and says what changed at the end.
• Typos and wording are fixed without an entry. Anything that changes a fact, a number, a command or a recommendation gets one.
• The tracker pages change all the time by design. They keep their own "Latest changes" list instead.

Report an error

Email hello@ajayk.sh with the page and what is wrong. A link to a source helps. Every post also has a report link at the end.
