Building my next SaaS on Rails.
The day something I made makes it to #5 on Hacker News is a day I’m camping and should be offline.

Significant milestones are easily missed.

Here's one we passed in the last 12 months at a SaaS I work with.

Worth celebrating?

Good morning!

Here's example of the kind of wild code that often breaks full page automated website screenshots.

Part of our team's job at Urlbox is to solve the resulting glitches so you don't have to.

This week’s indulgence.

Probably enjoyed by us a few more than 10 times over the last ten winters.

Thank you @nigelslater.bsky.social.

Rare that two of the businesses I'm working on are both doing this well.

These ProfitWell emails and other notifications play too big a part in how I feel each day.

I've now changed them so I only get them once a week.

2nd month running of processing over 1 million jobs on the first of the month using Solid Queue.

Took me 6 minutes and 30 seconds to enqueue them all.

Looks like it'll take a total of 6 hours and 30 minutes for them to complete at current pace.

For the next few days I'm hanging out with people from these ~100 SaaS-related businesses.

It's MicroConf Europe, a two-day conference focused on self-funded & indie-funded startups that have launched and are growing to 7-figure revenues & beyond.

Any you know or use?

Today I am running over one million jobs with Solid Queue using SQLite.

Loving Ruby on Rails on a Hetzner EX44.

I built a thing as fun side project at Urlbox.

It's a fresh perspective on the web. A way to explore over one million homepage screenshots. You can zoom, pan and click to navigate.

It's called One Million Screenshots.
(There are far less than one million in this image)
