I just bought my ticket, and
I also want to give away a ticket to someone that has never been to any Ruby conferences before to have a first experience. There is another condition, you will write a short blogpost about your experience and if they shoot video testimonials like last year, you will be willing to share how your first Ruby conference went.
If you would like it, reply to this tweet, or DM me and I will do a raffle in a month or so to pick a winner.

When I picked Rails as a new tool to learn over a decade ago, I watched the famous "Build a blog in 15 minutes" video from David.
There is a similar video for Rails 8 now, covering deployment too!

Did you know that you can define aliases with Kamal? It is great for often used commands like hopping into a Rails console:

What is a better way to celebrate the release of Rails 8 than watching my Rails World talk about the "State of security in Rails 8"?

@joeldrapper
> Because leaving it up to humans to remember never to render a link to a user-supplied hypertext reference is bonkers naive.

I think It isn't naive and keeping humans aware of the importance of security is important. And pointing out a few things where they can shoot themself in the leg helps with that. Many Rails devs already think that they don't need to care about security, the framework handles everything, but that will never be the case.

@joeldrapper Why would ERB protect you from something which is valid according to the HTML specification? "javascript" is a valid URL scheme and the developer should consider that fact when passing user controller value to the href tag.
A CSP is also not a silver bullet. It is easy to misconfigure it which allows it to be bypassed.
