I’ll absolutely fail any coding interview. Always have. But give me a problem and a model, not even a good one, and I’ll solve it. Pity companies haven’t caught up. The good news is, most of the market will end up like this as there are simply bigger problems so solve in a software stack, and this code nonsense is just a side effect. Be real, you’re gonna pay most devs to talk to codex or Claude. How about you test them in the actual environment. But no. Let’s find the next leetcode
Got turned down for a DevRel job. I didn't meet the technical bar on the coding challenge. Now I feel stupid. I've won developer awards and worked in DevRel for over 8 years, yet in interviews I come across as not technical, and I don't know how to fix that. Im so annoyed with myself.

Replying to @ThePrimeagen
I've been reflecting on this. I'm generally a very optimistic person, but lately I've been feeling a strange sense of sadness that coding has been "solved". I can, and have, made many caveats to "solved"... but I also know that in five years none of them will matter. It will be solved. Building things is still fun, but a different kind of fun. It doesn't activate the same parts of my brain as trad coding did. I think it's okay to mourn the thing we loved doing being different now. Software was the first job to go through the five AI stages of grief, which means we're also some of the first to internalize that this will happen to many other jobs. It was the best of times, it was the worst of times.

Health doesn’t happen alone. When one person starts paying attention to their health, it can change the people around them, too. Today, we’re launching Together in health: a story about the people who make healthy habits contagious. Follow along this week.

For most of modern medicine, the question has been: what’s wrong with you? We built Lucis to ask a different one: what if someone had looked earlier? Today, we raised $20M Series A led by Singular, with General Catalyst and Y Combinator to serve Europe.

Did not expect a question that starts out 'Do you think before you speak?' to go so well. A+ question from Charlotte Harpur A++ response from Eileen Gu.

Becoming a good engineer is about collecting experience. Each project, even small ones, is a chance to add new techniques and tools to your toolbox.
