I read everything and reply when I have something useful to say. If you’re reporting a broken example or a bug in one of the tools, include the page URL and what you expected to happen — it makes the fix faster.

Other places to find me

• GitHub — code, issues, and pull requests
• X — short notes and links
• LinkedIn — professional profile
• YouTube — the videos behind the articles

Before you email

• Bugs in the code: check the article’s page first — I usually post updates there when something breaks.
• Newsletter issues: unsubscribe links are in every email; if one fails, forward it to the address above.
• Guest posts or partnerships: I don’t do guest posts or sponsored content. el337 stays free and independent.

That’s the whole page. If you need the legal version of how I handle data, see the privacy policy.
