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.
GitHub Actions revolves around the concept of “workflows” and “actions”. Actions execute arbitrary Docker containers on top of a checked-out repository and workflows describe which actions need to be executed when a particular event occurs.
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 continuation
s in a web context. This
is a feature I’ve only ever seen in Smalltalk’s Seaside
though Racket’s version is more powerful.
It turns out that when you delete your Google accounts
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
and, lo and behold, there were a bunch of new posts I
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.
I decided to do this year’s Advent of Code in Racket and stream
the whole thing. We’ll see how far I make it (getting up this early
is rough!), but so far I finished day one. The code is here
and the playlist for the recordings is here.
If you want to get notified as soon as I jump on to start streaming,
you can follow me on Twitch.
