16 years ago today I wrote up and posted a proposal for a new calendar: newcal.org
Having long been frustrated by unnecessary unevenness and other quirks of the Gregorian calendar, I designed and wrote up a more ordered, mathematically simpler, and more continuously consistent calendar.
Building up from the atomic calendar unit of a 'day':
* five day weeks
* six week (30 day) months
* two month (60 day) + a sync day bims¹
* six bim years (minus a day for non-leap-years)
After giving it an obvious name, “New Calendar”, and somehow getting a short speakable .org domain (newcal.org), I wrote code to do all the calendar computations and conversions.
The simpler calendar computations made me realize I had invented something that would help solve a completely different problem I was working on: an efficient date-based storage format for my new blog.
It‘s rare that an invention, or reinvention of something inelegant, actually serves a useful purpose. This was one of those rare exceptions.
I also taught myself and have kept practicing the use of ISO 8601 Ordinal dates for my own personal calendaring, which literally gave me a new perspective of time. A much smoother and more linear progression of time across the duration of a year.

3D printed some more brackets for my battery charger wall
Thinking about the bad user experience around this emergency alert I got last night:
Emergency alert: Extreme
ENDANGERED MISSING ADVISORY. Details at https://bit.ly/EMA0022025
I was a bit suspicious, especially in light of the recent inaccurate evacuation alerts that went to all 10 million residents of Los Angeles County. A bit.ly link for an official government alert, really?
I used the bit.ly preview tool to see where the link would go before clicking (add a + after the bit.ly link). It showed the destination was the @CHPAlerts Twitter account, so it was legitimate after all.
I get that Twitter is still a good way to get out emergency alerts and you want links that pop up on phones to be short, but it would probably be better if they used a short link on ca.gov so it looks official.
Cleaned up my printer corner to make room for a new flatbed scanner!
🎉 Eight years ago today, the #IndieWeb Webmention protocol was published as a W3C REC https://www.w3.org/TR/webmention/
As a social web building block, #Webmention was designed to work with various other building blocks. Small pieces, loosely joined. Every year developers find new ways to work with Webmention, and new subtleties when combined with other building blocks.
The primary uses of Webmention, peer-to-peer comments, likes, and other responses across web sites, have long presented an interesting challenge with the incorporation and display of external content originally from one site (the Webmention sender), on another site (the Webmention receiver).
There are multiple considerations to keep in mind when displaying such external content.
Two examples of external content are images (e.g. people’s icons or profile images from the author of a comment) and text (e.g. people’s names or the text of their comments).
For external images, rather than displaying them in full fidelity, you may want to compress them into a smaller resolution for how your site displays the profile images of comment authors.
If you accept Webmentions from arbitrary sources, there’s no telling what might show up in author images. You may want to pixelate images from unknown or novel sources into say 3x3 pixel grids of color (or grayscale) averages to make them uniquely identifiable while blurring any undesirable graphics beyond recognition.
For external text, one thing we discovered in recent IndieWeb chat¹ is that someone’s comment (or in this case their name) can contain Unicode directional formatting characters, e.g. for displaying an Arabic or Hebrew name right-to-left. Text with such formatting characters can errantly impact the direction of adjacent text.
Fortunately there is a CSS property, 'unicode-bidi', that can be used to directionally isolate such external text. Thus when you embed text that was parsed from a received Webmention, possibly with formatting characters, you have to wrap it in an HTML element (a span will do if you have not already wrapped it) with that CSS property. E.g.:
<span style="unicode-bidi: isolate;">parsed text here</span>
Though even better would be use of a generic HTML class name indicating the semantic:
<span class="external-text">parsed text here</span>
and then a CSS rule in your style sheet to add that property (and any others you want for external text)
.external-text { unicode-bidi: isolate; }

This is what I woke up to this morning
Today I:
- found a buyer for all the Hue lights I decommissioned
- worked on the slides for the OAuth meeting on Monday
- updated IndieLogin.com and dependencies to work with PHP 8.2
- fixed the paper jam in Lily's printer
Built the entry closet in Unit A, and had a bike move to get everything out of storage!
Mačka being a cute loaf
remembering losing #aaronsw twelve years ago today, and drawing connections with:
* Lawrence Lessig’s https://lessig.tumblr.com/post/56888930628/on-the-emptiness-in-the-concept-of-neutrality
* Ben Werdmüller’s https://werd.io/2025/building-an-open-web-that-protects-us-from-harm
Two points of connection:
1. Neutrality in ethical or policy matters is insufficient, empty, and cowardly. Especially when you know better, neutrality in action is not ethical, it is negligent and wrong, like a lie of omission.
“Allyship demands more than neutrality — it demands action.” — @werd.io (@ben@werd.social)
“… there are obviously plenty of contexts in which to be ‘neutral’ is simply to be wrong. ” @lessig.org (@lessig.tumblr.com @lessig@mastodon.world @lessig)
2. Building community for collective action is required for resilient resistance
Aaron helped inspire and drive numerous acts of resistance against foes better funded and connected, many acts which succeeded to some degree or completely such as preventing the passage of SOPA.¹
Similarly he built community for collective action, such as co-founding the Progressive Change Campaign Committee and the Demand Progress political advocacy group² which remain active to this day.
One of the best ways to honor Aaron’s memory is to build on the good examples he set that succeeded and continue to succeed.
The only neutrality that Aaron supported was net neutrality, prioritizing those that use the internet over those that build & serve it, a priority of constituencies strongly aligned with the W3C’s official Ethical Web Principles.³
If you too reject neutrality and instead embrace allyship & action, some of those actions will require resisting the status quo with the intent of changing it.
If resistance with the goal of actual change is your primary objective (rather than recognition), build community to bring about that change, resist collectively not alone, both in the near term, and sustainably into the future.
Still miss you Aaron.
