@plexus The ticket site asks me to assign the diversity scholarship contribution to me/somebody else. I can just ignore that, right?

We are officially open for accepting sponsors for #heartofclojure! Here's our lovely Sponsor Prospectus which lays it all out in a spiffy slide deck

Now the fun* part of cold emailing starts, but if any of you lovelies already want to pass this on to "upstairs" wherever it is you happen to work or have connections, then that would be extremely appreciated.

@plexus Ansible, if it counts (I guess by modern standards there are 10x and 100x tools that do the same)

In light of Chrome's "DRM for web pages" proposal, let me just say that I've been using Firefox exclusively (mostly Nightly) for years. It's gotten really good. The devtools are great, the performance keeps getting better, excellent spec compliance. I really recommend checking it out.

My name is Arne Brasseur and I wholeheartedly endorse Firefox.

@plexus would love to, but the abnormally large design of tabs irks me the wrong way, and Firefox no longer has themes that change that, instead they now have something more akin to skins, not real themes they used to.

Ösi: »Hammas wirklich so gnädig?«

Piefke: »Haben wir es wirklich so eilig?« (»Pressierts uns a so?« für den Freistaat)

Oxford: »Are you really in such a hurry?«

Ernsthaft: Ich würde diese Idee nochmals überdenken. Hochgschwindigkeitsbahnstrecken können sich wegen der weiten Kurvenradien und geringen Steigungen der Landschaft nicht anpassen. Die dafür nötigen Trassen werden einfach in die Landschaft gekotz. Und verkehrsvermeidend wirken die auch nicht. Im Gegensatz zu einem weit verbreiteten Irrtum, spart Bahnfahren keine CO₂ sondern stößt nur weniger aus, als ein Fahrt mit dem Auto.

Episode 3 of #ActivityPubInClojure is up! It was really quiet on the chat, which was a bummer. Hope to get a bit more interaction on future streams. A few people posting in chat makes the difference between invigorating and mentally draining...

Stuff is starting to come together though, we've implemented our first two endpoints. We can generate test users, and see them pop up in the API. So a lot of the plumbing is there now and we should be able to iterate on the protocol stuff really nicely going forward.

Has really no one created a LISP syntax frontend for the Rust compiler, or is my google fu just failing me?

@plexus You mean, like Hy for Python, or Fennel for Lua?

I did find a few Lisp interpreters written in Rust, but that might not be what you meant.

Little Clojure tip: name sets as if they are predicates (where appropriate).

In Clojure it's quite common to use sets as functions (it acts as a function that tests membership).

(some #{a} coll)
(filter (comp #{1 2 3} :id) coll)

This is idiomatic, if you've done a bit of Clojure you will read this easily, because they are set literals it's quite obvious. But if the set is defined somewhere else, then suddenly it gets a lot less obvious.

(def admin-ids #{53 65 78})

(when (admin-ids (:id user)) ,,,)

In this case I would probably use an explicit contains?, at least that shows that it has to be a set or map.

(when (contains? admin-ids (:id user)) ,,,)

But you can also name the var as if it's a function

(def admin-id? #{53 65 78})
(when (admin-id? (:id user)) ,,,)

And this way you could refactor this later to actually be a function, e.g. something that checks the database.

@plexus I tend to only use sets as functions when it’s a set literal or otherwise very obvious that the value is a set. contains? makes it much more readable in most cases IMO

@plexus Isn't there quite strong concensus that functions ending in question mark should return boolean? Sets return the item, which isn't boolean, necessarily.
