aaronparecki.comDay 11: I dropped the web font in favor of a handful of system fonts for various platforms.Day 13: I added support for drawing curved maps lines to Atlas, which I use to generate the maps on my site. Now my travel plans show a nice line for each flight leg.Day 16: I improved the display of comments on my posts, including displaying some basic HTML formatting from comments, autolinking comment text, and showing images.

Quill started out as a sample Micropub client with a lot of useful debugging information. As it's grown, I've been slowly adding more posting interfaces to Quill, and tweaking them to look less like a debugging tool and more like a real app. Instead, micropub.rocks has taken over as a more detailed debugging utility for building a Micropub endpoint, so I can now optimize Quill for being more user-friendly and less developer-focused. At IndieWebCamp Germany in 2015, I added a rich editor to Quill, inspired by the clean Medium interface. You can even use the Quill rich editor without being logged in! It will save the post to your browser's localstorage as a draft, and let you post it after you log in. I wanted to make an interface that anybody would feel comfortable writing in, and be able to show it to people without them first logging in, as an introduction to what it might look like to have nice writing applications that aren't tied to a specific backend like Medium.In order to help people get started with Quill, today I wrote some more documentation for it!When you're logged out and click the "publish" button, it prompts you to log in and links out to the documentation home page.

Today I started autolinking the text in comments on my website, and made a couple other minor improvements to how they look.Previously, links, @-names and hashtags were rendered as plaintext, so comments weren't clickable.

I've been using Quill to write all these #100DaysOfIndieWeb posts, which is a great way to find the pain points in the interface. After having written 14 articles in the last 14 days, the main thing I want to be able to do is start an article here in the Quill editor, save it as a draft to my website, then open up the raw HTML to make fine-grained edits, and only after I'm done, actually publish it.

If you know me, you probably know that I log everything I eat and drink and post it to my website. A couple years ago, I wrote a small Pebble app that allowed me to quickly post common food and drink from my watch! Coincidentally around the time Pebble announced that FitBit had acquired their assets, my Pebble stopped working completely. This meant I no longer had a quick way to log food, and have to pull out my phone again to make log entries.This afternoon, Tantek suggested that I use my Amazon Alexa to post food and drink to my website instead! Of course this will only work when I'm at home, but it turns out that I'm home a lot of the time I'm eating and drinking. I also eat tacos every day, so it'd be great not to have to get out my phone during breakfast.So today, I launched Alexa integration for Teacup, the app I use to track my food.This was quite a challenging project given all the moving parts involved. I started by defining the voice interface I wanted to use. Interaction ModelVoice interactions for Alexa apps have to follow a pretty strict structure. Alexa doesn't support interpreting fully unstructured text, so app developers have to define patterns that Alexa can match on. Invoking any Alexa app involves first speaking the trigger word, followed by a keyword such as "ask" or "tell" followed by the app name, and then the pattern of text the app wants to match. So for Teacup, this results in speaking sentences such as:"Alexa, tell Teacup I drank coffee""Alexa, tell Teacup I ate tacos"This gets turned into what Amazon calls the "Interaction Model", and is a list of "slots" along with corresponding keywords for each slot, as well as writing out some sample sentences.LIST_OF_ACTIONS = ate | drankLIST_OF_FOOD = Coffee | Cocktail | Beer | Tacos | Mac and Cheese | ...Sample utterances:"I {Action} {Food}""I {Action} a {Food}"It isn't clear to me whether the list of keywords I provided is the complete set, because while I was testing, it managed to post the word "on" for the food, which is not in my list.AuthenticationThe next challenge was linking user accounts between Amazon users and Teacup users. Amazon provides great documentation on this, and thankfully it's all based on OAuth 2.0 rather than having made up some other model themselves. Essentially, the Amazon Alexa app on your phone acts as an OAuth 2.0 client, and you have to build an OAuth 2.0 server into your app that it works against. This is a pretty clever solution actually. Luckily, I'm pretty familiar with OAuth 2.0, so I was able to build this out pretty quickly.One thing struck me about Amazon's recommendations about building OAuth support in your app. They say that they'll launch your authorization URL from inside the iOS app, which is a known antipattern for apps in general. In Amazon's docs, it says "The user logs in using their normal credentials for your site." This is a really bad idea. You never want to train your users to enter their passwords into random apps. This is the whole reason we have OAuth in the first place!

Yesterday, Amy was asking if there was a library for drawing curved lines between two points on a map. She wants to use this for her travel posts, which say for example "Tokyo to Boston". We noticed that Facebook draws curved lines when they show a planned trip. Martijn was able to figure out how to reproduce this on Facebook consistently. You have to start by creating a "checkin" post, then add a "traveling to" activity to it. Notice that the line from Portland to Seattle is curved rather than straight, although it doesn't strictly follow a Great Circle line either.
