The last code I wrote by hand was a sql query, 5 months ago. Fitting. whats yours?

I didn’t vibe code this and it sends email for you while also helping you understand marketing and how to be a good writer. Good vibes here, not slop code. Keep telling me I can’t, because I am, and I know how. kolea.pro

Making this transition this week. It’s so much better though I will say it can be super confusing moving between machines and phone etc.
Most devs use Claude Code in the terminal, but why? The desktop app feels cleaner and more organized, and from what I can tell it offers the same core features. Am I missing something? Is the CLI actually more powerful, or do developers just prefer terminals?

This is the 5th post I’ve seen like this. Streisand effect incoming.
A very serious warning to anybody thinking about building their own email delivery service: don't do it. Every email that ends up in spam is lost revenue and opportunity for you. Getting deliverability right is extremely hard and it's not something you should vibe code.

I made a fun thing over the last two months. I wanted to replace Kit, Ghost, that testimonial site, and ThriveCart with just what I needed, wrapped up in something gorgeous, with deep reporting numbers. Today I'm sharing it! kolea.pro/

No, it's not vibe coded and no, it's not slop. It's built on Elixir flexing everything BEAM is good at. I've run it through 3 different review guantlets for system design, and have been using it for my own newsletter now for the last month and it's worked almost flawlessly. Having loads of fun and thought I would share.

This reminds me of a conference talk I gave discussing Elixir's "speed". I showed the "benchmark" for writing 100,000 records to postgres with a single query process, which was OK. I then fanned out 10 processes that chunked the job into 10 batches of 10,000 writes, and then 100 batches of 1000 writes, completely pinning Postgres' 100 connection limit. I do wonder what this would look like in the hands of a capable Elixir/OTP person. Perhaps it was and I'm completely wrong (would love to know!). And I'm not trying to throw shade - my entire point is simply that you shouldn't choose a language/platform because of "speed". There are so many tradeoffs here.
It's time to stop using slow programming languages. I don't think you understand the magnitude of this situation. Let me explain.

The video uses final benchmark numbers from a Rust implementation refined over hundreds of commits with extensive performance work versus Elixir/Go ports with only a few commits and minimal optimization. github.com/basecamp/once-… github.com/basecamp/once-… github.com/basecamp/once-… github.com/basecamp/once-… github.com/basecamp/once-… x.com/josevalim/stat…

It's interesting reading all this back and forth about Elixir and Rust and system design. It is so tempting to think that you could have Claude and that you can just build a resilient system because you're using a fast language or bullet proof frameworks like OTP. But with those things come many footguns. I have used Elixir for years, and I would never assume that Claude will get this right. Benchmarks will not cover the crazy landmines that distributed, concurrent programming offer. If anything, Claude makes it *easier* for you to screw yourself into a corner. I'm in the middle of this right now, trying to optimize fast network sends + resilience + write speed (Postgres) while avoiding write locks, fail locks, and complete failure because things are either moving too fast or too slow. This isn't something you can trust Claude with... honestly I barely trust myself!

Finalllyy got around to updating and upgrading my dear friend Moebius, an Elixir data access library. I revved to v5 and ripped out Postgrex I favor of a driver that’s > 1.0 to keep things from breaking. And doubled the test surface, and picked up some speed along the way. github.com/robconery/moebius

It’s bonkers how useless Siri is, even with the AI stuff plugged in. All my normy friends are using Claude and ChatGPT and ignoring Siri completely. Slow, buggy, weird is the best I can describe it.

I don't know if it's a good idea, but I suppose I don't care I'm having fun. I like Ghost a lot, but there's so much more we can do, I think. What started as a fun little side project is growing into a publishing platform I wished I had years ago... and then some. github.com/robconery/kolea

Powered by the tiptap editor, deploy to Cloudflare and use Resend to keep costs low. Stripe integration with analytics everywhere so you know what's working and what's not. AI slop detection (without AI), templating... I'm only getting started :)

In other words: invest in Nike
BREAKING: After falling -80% from its record high, Nike, $NKE, will be removed from the S&P 100 at the end of this month, ending a near 18-year run in the index. The stock has now erased -$230 billion in market cap since its all time high. A collapse for the history books.

I wonder if you could bake productivity hacks into an OS like @OmarchyLinux. A full PARA file system, for example, just to help organize things in a sane way. Yes, I know that Arch has it's Linux structure but maybe ~ could have something productivity-focused? That would turn HOME into a PKM of sorts. What do you think @dhh? Calendars, tasks, all kinds of groovy stuff backed into a beautiful system...
