Help
How can I help?
This is a personal blog, not a product — so "help" mostly means pointing you at the right thing or answering email. Common topics below.
Reading the blog
Every article has a category (Basics, Core Patterns, Highload, Real Domains) and a set of tags. Use the filters on the /blog archive to narrow by topic, or the search box to find articles by keyword.
RSS feed
The full feed is available at /rss.xml. New articles appear there within minutes of publishing.
Using code from articles
Code snippets in articles are shared under a permissive license (MIT unless stated otherwise). Feel free to adapt them in your own projects — an attribution link is appreciated but not required.
Reporting mistakes
If you spot a factual error, typo, or broken link — email the address below. Corrections usually go out within a day.
Suggesting topics
Open to topic suggestions, especially if you're wrestling with a specific production problem. No guarantees, but most articles here started as someone else's question.
Everything else
If none of the above covers your question, just send an email. Responses usually within a couple of days.
Still need help?
Email is the fastest way to reach me. Please include a link to the article if the question is about specific content.
