What's the connection between Heroku, my son, a coffee shop, and productivity?
Once, I asked to send mass emails from Heroku via a script. How dare I connect to the console and run it there! First of all, I made a mistake in predicting the operation.

I'm excited to share that my open-source projects have passed 𝟜𝗺 𝗱𝗼𝘄𝗻𝗹𝗼𝗮𝗱𝘀! It's amazing to see how far they've reached and how they're helping others in the 𝗥𝘂𝗯𝘆 𝗰𝗼𝗺𝗺𝘂𝗻𝗶𝘁𝘆. I'm really grateful to everyone who has 𝘀𝘂𝗽𝗽𝗼𝗿𝘁𝗲𝗱, 𝗰𝗼𝗻𝘁𝗿𝗶𝗯𝘂𝘁𝗲𝗱, or 𝘀𝗵𝗮𝗿𝗲𝗱 𝗳𝗲𝗲𝗱𝗯𝗮𝗰𝗸 along the way. rubygems.org/profiles/ka8...

#AI is transforming sales at a frightening speed. I’ve never seen messages this targeted and direct from past "lead generators". Should I trust them? Still doubtful.

Today, I came across this. I was a bit surprised by the obsession with using correct English grammar even in method names.

After 2 months as a "teacher," my 9yo finally read, understood & implemented a task alone. Teaching how to grasp requirements is so hard—wild how I once learned it myself. The gap between us is fascinating—but it shrinks a little every day. Watching it happen is just amazing!

Efficient and productive #WebDev without #SQL? I don’t think so. I’m strong in #Ruby — better than in #SQL — but with SQL, I’m 5x (or more) productive when tackling data-related issues. #SQL is as fundamental to web development as logic is to math. It’s the foundation. Period.
