We have a responsibility to learn the underpinnings of the standard of living we all enjoy. To understand and appreciate how we got here, and what it took. And ultimately, to keep it going

To hold someone's attention with a blank slate, all that's necessary is to put another blank slate beside it. You don't have to write anything on either of them. I start to think about the many selves I project, and how the phones work to align them beside themselves, inviting comparison.

I don’t want to suggest that we should resist change entirely. I do think we can be thoughtful about the rate of change that we introduce. I also think it’s a choice, rather than an inevitability, to drop bombs that throw an entire ecosystem off-balance. I tend to interpret this dismissiveness as a way of saying, “We don’t want to become a ‘thing’ because ‘things’ are destroyable by outsiders.” Avoiding labels is a way of keeping hidden cities away from the colonizers, like a nomadic tribe on the move.

i let summer take over the house for however long it needs --- making their way from meal to meal across the sky --- it’s not quite true that every car should stop while a poem is in operation but try to tell me it wouldn’t be nice

The problem, and it’s obvious, is that whatever sucks that I’m running away from will be there once I stop working. or doing things like not being available on the weekends, because they’re the weekends.

but `parseNonEmpty` gives the caller access to the information it learned, while `validateNonEmpty` just throws it away. Consider: what is a parser? Really, a parser is just a function that consumes less-structured input and produces more-structured output.

Lenses have gained some traction in the functional programming world, mainly in haskell. However, they are still viewed as a largely complicated, difficult, high level concept that is not really worth it to invest in learning or putting in your code base. It can be hard to get a good overview on what they actually are and how one can use them. They seem to be somewhat related to getters and setters, but what does that really mean? In addition, it seems to be one of the deepest rabbit holes around. Surely something like this can't be of interest for an everyday working programmer, trying to solve real world problems? Wrong! In this talk, it's my goal to give a brief overview of what lenses are. But more importantly, I will also try to present a "slice" of the world of lenses that is not only directly applicable and useful in our daily work, but is also strangely familiar to people coming from an imperative/object oriented background. Sara Fransson Sara is a software engineer by day and a math enthusiast by night. Sometimes the two worlds collide (and sometimes they make them collide by banging them together). After having taken several trips back and forth between academia and industry in an attempt to balance their love for both the pure abstract theory and the practice of leveraging it to solve concrete problems, they have landed in the core banking domain at Klarna. There they are making themself busy spreading the gospel of functional programming and type theory. When they're not busy building a bank or trying to find time for studying, they enjoy cooking and eating tasty vegan food and playing tetris as fast as possible.

How would you attack a pass code entered into a keypad without an "enter" key? Would requiring an enter key improve security more than requiring another digit?

I think doing math professionally can be stifling as it can feel like you’re expected to know everything while staying collected. This blog is my outlet to do my best to grow as a mathematician while giving myself and others permission to be wrong, ignorant, and emotional about math!

We also saw it’s possible to multiply things that aren’t numbers, and in that case we may not have... associativity, for instance. But that’s not a bad thing. In fact, it’s a beautiful thing!

the more I try to focus on what I genuinely love. The stuff that really nourishes and feeds me.

I say ‘feasibly’ because often the upper end of career ladders for Independent Contributors (ICs) could be paraphrased as “we’ll know it when we see it”, which can leave those who haven’t sufficiently proven “it” in a frustrating limbo. ​ I’ve worked very hard to become an engineer and I want to stay here. ​ Developing prototypes to further explore and support ideas that come from that research.

So even a little familiarity—the amount you gain from one steely sit-down with the thing—can dislodge major chunks of fear. For good.

I felt joy, and a familiar pang of shame that comes from realizing you’ve moved too fast to cherish what’s in front of you. ​ The truth is, I don’t always want this kind of life. ​ I wish slowing down didn’t feel like a luxury.

The thing I try and tell myself every week: Just because people don’t want to hear it doesn’t mean it’s not true. And just because this work is relentless doesn’t mean it’s not worth it. ​ It’s difficult to explain that patriarchy means rule and control by men, power held by men, and the generalized idea that men are more valuable and important — and that that can be true even if some women have some power. All sorts of people, and not exclusively men, can be involved in its preservation; the vast majority of the time, they’re not aware they’re doing so. Institutions help sustain patriarchy, but so do individuals and traditions and clothing norms and religious beliefs and health insurance benefit plans and air conditioning standards.

So the assertion that technology companies can’t possibly be shaped or restrained with the public’s interest in mind is to argue that they are fundamentally different from any other industry. They’re not. ​ an echo of the very ethos that founded America: progress at all costs. ​ and it’s time to question what “progress” actually means.

A beauty and order that language fails to describe but math, art and music do a better job of conveying. That against all odds, I - a collection of atoms consisting mostly of empty space - has the chance every single day to experience and explore this incredible universe. ​ And that the only logical thing in the face of all these realizations is to enjoy, celebrate, and try my best to preserve that beauty.

Forming the set of equivalence classes is called “modding out” or “quotienting by” the equivalence relation.

of work I poured into our course blog. Every student contributed two posts to the blog, and I gave multiple rounds of detailed feedback on all twelve posts, learning a lot from the students in the process. ​ and especially not Jekyll, since having a working Ruby environment is the hardest problem in computer science

I love functional programming, […] and developing intuition behind complex topics. Thus G [some group] is a category with one object, in which every arrow is an isomorphism.

Imagine the pressure of having to top each successful thing you do. This thinking assumes that you must be constantly on top, not only against your peers but also against your past self. Even worse, this thinking assumes that if you cannot win then you must stop playing. But what about the joy of learning, the quiet glory of just making things and sharing them without expectation? No, when your time is up you’re free to go. At the end of the day, the only thing perfect is a blank page, I think there is something inside me and I want to find it.
