I’ve generally had a hard time accepting kindness from others due to fear of inconveniencing others This is definitely one of the pitfalls of working alone as an indie maker. It allows me to indulge that tendency and try to do everything myself rather than building relationships and learning that it's okay to depend on others.
All those things aren’t how we measure success—we only think of the big things like falling in love, finding a great job, making a beautiful thing. But cleaning the dishes and doing laundry is what really stands in the way of the big things and us.
When I talk about [underdeterminism], I jokingly give the example of where Twitter would be today if the service had been built strictly as a way to share information about baseball games.
A cross between a text message thread and a blog post about inter-generational conflicts, Boomer as a state of mind, cultural differences between Zoomers and Millennials, and what it feels like to grow up Very Online.
In pandemic times, fears of waldenponding seem less applicable. It's not about building a new city or society, but a transient, protected retreat. (e.g. the Recurse Center). …It seems valuable to shield these sorts of endeavors from an environment that's increasingly hostile to knowledge work.
In the early 2000s social media sites like Facebook and Twitter weren’t commonplace yet. Even text messages, at ten cents each, were something to be rationed. For many teenagers the primary means of communication outside school was AOL Instant Messenger (AIM). So when it was announced in October that they were shutting down AIM after 20 years, I felt a wave of nostalgia for the messaging app of my youth.
For myself, when I read this many years from now. I woke up and Miranda had decorated the kitchen with giant 3-foot shiny golden balloons: 40! There was an incredibly lovely cake from Sparrow Bakery and cards that made me cry both from her and from Ruby. Ruby is just 2 years old. She’s so […]
Richard Borcherds’ first of three lectures on p-adic numbers
This is the first part of a 3-part talk on p-adic numbers for advanced high school students. It is part of a series organized by the Berkeley mathematics circle.
We define the 10-adic integers, which are similar to ordinary integers except their decimal expansion can be infinitely long. We show that one can do addition, multiplication, and subtraction with them. However they have some problems because it is possible for two nonzero 10adic integers to have zero product. We will see how to fix this in the next video.

The act of donut-eating has actually helped me feel like I’m accomplishing my career goals. […] I found that it resonated with others, especially young career-driven women who are routinely achieving goals and furthering their career but don’t take the time to note their own success.

If you want to check it out, I feel compelled to warn you that it's not the most well-documented tool, and it has many other quirks you might expect in a library someone wrote with only their own use in mind.

This next project might take one year, five, or twenty, but it is not you. You are a superset of what you do, not a subset. Narratives based in past behavior are by definition out of date. Sometimes allow yourself to just be open to possibility of the next moment being different. How does the story change in this moment? The key to talent development of yourself and others: propulsion off cliffs with parachutes one size too small. Sometimes you land hard but your wings build muscle.
Using Twitter the other day, finding myself sucked into a far-off event that truly does not matter, it occurred to me that social media is an orthographic camera.
Gracie, I can’t reach out to you online, but this is my response as a mathematician. I hope it helps someone. These kinds of questions you are asking are what drive us as a profession. It doe…
and while you may enjoy being a specialist or a generalist for some time, you never really know when your situation could change and when circumstances may warrant otherwise. Or, when you might simply feel like trying something new.

Featuring the distinctive vocals of Zoë Johnston, "You Got To Go" is the latest single to be taken from Above & Beyond's critically acclaimed second artist album "Group Therapy" -- described by Mixmag as "the biggest artist album of the year".
Following in the footsteps of Above & Beyond's BBC Radio 1 playlisted singles "Sun & Moon" and "Thing Called Love", the more optimistic "You Got To Go" is a song about seizing the moment and taking control of the opportunities in front of you.
Inspired by Kyau & Albert's energised club remix of the original album version, the A&B vs. K&A Radio Edit combines the melodic riff-driven energy of the Kyau & Albert remix with a more radio-focused approach - capturing the song's beauty and orchestral touches perfectly.
The release package will also include a brand new club mix from Above & Beyond themselves, the high-energy Kyau & Albert remix, two contrasting remixes from the legendary MJ Cole and an organic tech-house version from upcoming duo Dusky.
There are DJs who can rock a party, a club, a festival. And there are acts that can write songs that will bring out the goose bumps in you. But there's only one band that can do both: Above & Beyond.

Finding out if a sequence of digits is a “numpad path”
I noticed that several of my old credit cards have verification codes which have an interesting property which I'll call "numpathable".
A numpad is a graph that looks like this:
7 - 8 - 9...
I’d never considered that adaptation was a serious option, until we started talking about it like it was a tangible problem and not a nebulous threat. Trying to find a pathway towards the source of pain is a lot more empowering than pouring your energy into being bitter over someone else’s success.
Think about blogging for a second: the fact that a list of posts is ordered chronologically by publication date, by default, is a bug in our incrementally-correct worldview. Blogging tools don't create any incentive to go back and edit previous ideas or posts. Or, at the very least, the default ordering has a de facto side effect of fewer people being aware of revisions or reversals to previously-published ideas.
“One of the few positive effects of these scary times is the increased interest in skateboarding. It’s been uplifting to see so many learning to skate in their “downtime.” I believe they’re in pursuit of the same feeling this Ukrainian girl got when she landed her first kickflip.”
So the optimal thing for you to do, whether you’re an open source software developer or a Twitter armchair analyst, is to figure out your specialty zone that’s simultaneously useful, but unique – and then homestead it. Establish and cultivate it, like a garden or a plot of land, that you’re tending for the communal benefit of everyone. People come to associate that little plot of land with you specifically, and think of you whenever they go near it.
