Example of debugging an http endpoint (or function in general) in Biff (or Clojure in general)

Ratings API

I just added an API endpoint which gives you all your ratings as JSON. You could use it to e.g. fetch all your favorited articles and send them to your aunt. You can enable it from the settings page.

Also, Findka Essays has been a little flaky this week. There have been a couple days when it hasn't sent the emails out. I can trigger them manually, but I, uh, sometimes get distracted. Anyway, I've tweaked some things and hopefully it won't be an issue anymore. But either way, I'm keeping an eye on it, and I'll dig in further if the problem persists.

How to make your own airtable bookmark bookmarklet
View bookmarklet.js
// 1. Create a table on Airtable, and make URL/text columns with these names:
// URL, Title, Description, Image, Feed
// 2. Add a Form view. Click "Open form", then copy the URL. Set `airtable_form_url`
// below to that URL.
// 3. Create a new bookmark in your web browser, and paste in the code below. Whenever
// you're on a page you want to save, click the bookmark ("bookmarklet", technically).
// You'll go to the airtable form, and the columns listed above will be prefilled.

Better logs for Datomic Cloud Ions

You may discover soon after adding logging to your Ions that CloudWatch really sucks. Fortunately you can forward your logs to Loggly instead. See here.

Modifying Datomic schema for composite tuples

Say you define a composite tuple like so:

#:db{:ident :foo,
     :valueType :db.type/tuple,
     :unique :db.unique/identity,
     :tupleAttrs [:bar :baz],
     :cardinality :db.cardinality/one}

Now suppose you want to change [:bar :baz] to [:bar :quux]. The [Datomic

tools.deps bug with :local/root?

On a project I'm working on, this gives me an error:

$ clj -Sdeps '{:deps {trident/build {:local/root "/home/arch/dev/trident/target/build"}}}' \

Exception in thread "main" Syntax error compiling at (trident/build/util.clj:1:1).

(I have (:import (jnr.posix POSIXFactory))) in that file).
