Yesterday, I bought an icon pack containing over 3,000 (!) SVG files and macOS utterly failed me when I tried to search the unarchived folder.

So I did what any self-respecting Racketeer would do. I used this as an excuse to play around with Racket’s built-in GUI library!

I just released the first version of marionette (named after the protocol it implements), a Racket library that lets you remotely control the Firefox web browser. Think “puppeteer”, but for Firefox.

Like Alex Harsányi, I’ve been looking for a good, free-as-in-beer, alternative to Travis CI. For now, I’ve settled on GitHub Actions because using them is straightforward and because I saves me from creating yet another account with some other company.

After hacking the matrix.org website today, the attacker opened a series of GitHub issues mentioning the flaws he discovered. In one of those issues, he mentions that “complete compromise could have been avoided if developers were prohibited from using [SSH agent forwarding].”

One of the distinguishing features of Racket’s built-in web-server is that it supports the use of continuations in a web context. This is a feature I’ve only ever seen in Smalltalk’s Seaside before, though Racket’s version is more powerful.

It turns out that when you delete your Google accounts, Google unsubscribes you from any (public and private) Google Groups you’re a member of. I found out about this only because my inbox traffic these past couple of days felt unusually light so I went and looked at racket-users and, lo and behold, there were a bunch of new posts I hadn’t received.

I spent this past weekend de-Google-ifying my life and, despite my expectations, it wasn’t too hard to do.

Today marks the first public release of forms, a Racket library for web form validation. Racket’s formlets module from the standard library already does something similar, but, unfortunately, it lacks any facilities for easily showing validation errors to end users which is a big part of what I want from this kind of library. Another nice thing about this new library is it’ll be able to validate things other than forms – like JSON – soon!

Since Microsoft officially announced that they will switch Edge’s rendering engine to Chromium, many people have written about how this poses a danger to the future of the web. I’m not going to repeat those same arguments, as I feel others have done a good job of it. What I want to do is urge you to try Firefox for a couple of days this week. That’s it. Give it a try.
