Are you getting "SPF alignment issues" or "spf=neutral" for emails sent by WP?

Turns out that wp_mail() doesn't set the Return-Path email header which leads to PHPMailer populating that from the php.ini sendmail_from setting. While that is correct, email clients these days expect the FROM domain, Return-Path and DKIM p= domain to be equal to pass the DMARC checks.

Here is a crazy idea — use JSON with actual JS for config files. So many JS and PHP projects seem to embrace it now over plain JSON or YAML files.

Was listening to this interview with Sam Goodwin on devtoolsFM podcast about Alchemy and realized how cool it is to have actual programming language features for configs.

Why is naming things hard? 🏷️ OpenAI is such a young company but their user-facing product names look like this already.

Native <video> in HTML is extremely good these days. Videos encoded with H264/AAC are universally playable and with HTTP chunk support you can serve the same video to all users.

However, browsers seem to request videos with preload=auto/metadata as soon as the page loads which is unnecessary. So I built this lazy-load solution that hides the src attribute (prevents loading) until an Intersection Observer callback.

WordPress would be perfect for this kind of personal AI buttler — we have a simple table for memories and cron runner for scheduled tasks. https://www.geoffreylitt.com/2025/04/12/how-i-made-a-useful-ai-assistant-with-one-sqlite-table-and-a-handful-of-cron-jobs

Which one do you use the most? Which blew your mind the first time?

Responded to @kasparsd:

Optional Chaining & Nullish Coalescing 📜 ES2020

const what = user?.profile?.name ?? 'N/A';

Reads the value of name without undefined crashes, and returns 'N/A` if not present.

Responded to @kasparsd:

Object.fromEntries() 📜 ES2019

const entries = [ ['a', 1], ['b', 2] ];
Object.fromEntries(entries);

returns { a: 1, b: 2 }.

Responded to @kasparsd:

Object.entries() 📜 ES2017

const obj = { a: 1, b: 2 };
Object.entries(obj);

returns [ ['a', 1], ['b', 2] ] which is useful for mapping.

Responded to @kasparsd:

Property Shorthand 📜 ES6 (2015)

const x = 1, y = 2;
const point = { x, y };

Less typing, same object.

Responded to @kasparsd:

Object Spread for Merge 📜 ES2018

const a = { x: 1 };
const b = { y: 2 };
const c = { …a, …b };

Merges like magic (shallow copy).

Responded to @kasparsd:

Computed Property Names 📜 ES6 (2015)

const key = 'foo';
const obj = { [key]: 123 };

Turns variable value into a property key. Syntax sugar for obj[key] = 123.

Responded to @kasparsd:

Nested Destructuring 📜 ES6 (2015)

const user = { profile: { name: 'Ada' } };
const { profile: { name } } = user;

Same as name = user.profile.name;

And you can rename the variable name to userName:

const { profile: { name: userName } } = user;

Responded to @kasparsd:

Destructuring with defaults 📜 ES6 (2015)

const { foo = 'default' } = {};

Sets the default value of foo to 'default' if the value isn't defined.

JavaScript object tricks that look weird but work wonders (and when they were added to the language.

If you've ever seen { [key]: value } and thought “what the heck?” — this thread is for you.👇

Was chatting with an AI about Zero-Knowledge (ZK) proofs and how they relate to backtraces and public-key crypto (concepts I know):

> Imagine a PHP backtrace, turned into a spreadsheet, hashed into a Merkle root, and then proved using fancy math that it obeyed all your function contracts without ever showing you the contents. 🤯

Built the ultimate login/logout block that works with the WP core navigation block. Use it to:

– Display only the logout link for logged-in users.
– Display only the login link for anonymous users.
– Specify a custom page (any post type) as the login destination.
