Maybe I should move to Germany. I really do need more sausage metaphors in my life.

The @thinkingelixir.com podcast covered my Postgres WAL blog post! What an honor and pleasure to hear Mark and David discuss the WAL and reminiscence about the horrors of stored procedures :D

Just published OGI v0.2 which adds an fallback image path, better docs (thanks @gworkman.bsky.social!) and makes the library more well-rounded.

TIL: `--seed 0` disables the randomization of ExUnit tests, essentially ensuring the tests will run in the declaration order. Very useful when "watching" & using `--max-failures 1` to get consistent output as you TDD hexdocs.pm/ex_unit/1.19...

Y'all, I need help testing if this implementation of Open Graph images works properly.

If everyone who reads this could send the link to 20 friends and remind them that the next Nerves meetup is on Wednesday that would be soooo helpful 🙏😜

This post inspired me to write a Typst-based alternative to @derrickreimer.com's OG-Image that you can deploy together with your Phoenix app.

So, introducing: OGI!

Got my little app deployed last night. If you think Kamal + Hetzner is a replacement for Heroku then you really *really* have never understood the value of Heroku.

Deploys are quite fast now but setting up Kamal is like "so you start with an already drawn owl, now…".

Looks like X is juicing web visit numbers by opening a browser WebView in the background whether the user visits the link or not.

They've re-invented pop-under fraud (allegedly).

news.ycombinator.com/item?id=4580...
Tell HN: X is opening any tweet link in a webview whether you press it or not 247 points by stillatit 10 hours ago | hide | past | favorite | 200 comments Just saw the CEO of Substack celebrating traffic from X/Twitter shooting up thinking they stopped suppressing tweets with links[0]. Actually, this traffic is because now any time you open a tweet with a link, the in-app webview loads in the background, and displays when you press the link. I run an ecom store that gets a lot of its customers from Twitter. I was also shocked to see my traffic double or triple overnight and thought the algorithm had blessed me and my business. Soon realized what was actually happening. Thought other traffic-monitors might appreciate this explanation. Meanwhile Nikita Bier is pretending they never suppressed tweets with links to begin with, offering the alternative explanation: "a common complaint is that posts with links tend to get lower reach. This is because the web browser covers the post and people forget to Like or Reply. So X doesn't get a clear signal whether the content is any good"[1]. A bit of a rewriting of history since Elon and his mom both tweeted about how it wasn't fair to use his platform to promote other links/platforms, even banning people who shared profiles of other social networks (including Paul Graham for a period). They suppressed all links shortly after. [0] https://x.com/cjgbest/status/1985464687350485092 [1] https://x.com/nikitabier/status/1979994223224209709

Thanks everyone for your UI suggestions for my blog.

I just added light mode, a table of contents, anchor links for headings, and no more "CANT FIND ZE INTERNYET" banners.

Should make it easier to read and share my blog posts ;-)
