Back in 2017, I was building a rich text editor in the browser. Unsatisfied with existing libraries that used ContentEditable, I thought to myself “hey, I’ll just reimplement text selection myself! How difficult could it possibly be?” I was young. Naive. I estimated it would take two weeks. In reality, attempting to solve this problem would consume several years of my life, and even landed me a full time job for a year implementing text editing for a new operating system.

Rendering text, how hard could it be? As it turns out, incredibly hard! To my knowledge, literally no system renders text "perfectly". It's all best-effort, although some efforts are more important than others.

Freedom is a funny word. It's a hard thing to talk about because to a degree, if this kind of thing cuts down, let's say, on random crime, then it's going to make people effectively freer. Especially if you're a woman or someone who is vulnerable to being the victim of random crime, if some kind of surveillance system renders that less likely to happen, then effectively you've been granted a freedom that you didn't have before. But it's not the kind of statutory freedom that we tend to talk about when we're talking about politics.

Here's the point of the whole thing. The IETF people, when they were thinking about IPv6, saw this mess getting made - and maybe predicted some of the additional mess that would happen, though I doubt they could have predicted SDN and wifi repeater modes - and they said, hey wait a minute, stop right there. We don't need any of this crap! What if instead the world worked like this?

A tool for exploring a docker image, layer contents, and discovering ways to shrink the size of your Docker/OCI image

Putting a fat jar into a Docker container is a waste of storage, bandwidth and time. Fortunately, we can leverage Docker’s image layering and registry caching to create incremental builds and very small artifacts. For instance, we could reduce the effective size of new artifacts from 75 MB to only one MB! And the best is that there is a plugin for Maven and Gradle handling everything for us.

The FIRE (Financial Independence, Retire Early) movement is a lifestyle movement whose goal is financial independence and retiring early. The model became particularly popular among millennials in the 2010s, gaining traction through online communities via information shared in blogs, podcasts, and online discussion forums.

Those seeking to attain FIRE intentionally maximize their savings rate by finding ways to increase income or decrease expenses. The objective is to accumulate assets until the resulting passive income provides enough money for living expenses in perpetuity. Many proponents of the FIRE movement suggest the 4% rule as a guide, thus setting a goal of at least 25 times estimated annual living expenses. Upon reaching financial independence, paid work becomes optional, allowing for retirement from traditional work decades earlier than the standard retirement age.

Another type of American Dream has now developed: The freedom to upturn your desk, give your boss the finger, and retire on the spot—without making a lifestyle sacrifice, of course.

In some circles, the wealth required to burn any bridge you want has a name: “f–k you money.” That’s because, well, backed by the First Amendment and a large fortune, you can yell that without consequences to pretty much anyone, save for a judge, a plumber, or a tax assessor.

I decided then to write up the practices that I think lift a newly minted software engineer from amateur to professional: the path from fixing bugs as an “Engineer 1” to leading major projects as a “Senior Engineer.”

Mindfulness is nothing more than basic concentration training. Although derived from Buddhism, it’s been stripped of the teachings on ethics that accompanied it, as well as the liberating aim of dissolving attachment to a false sense of self while enacting compassion for all other beings.

What remains is a tool of self-discipline, disguised as self-help. Instead of setting practitioners free, it helps them adjust to the very conditions that caused their problems. A truly revolutionary movement would seek to overturn this dysfunctional system, but mindfulness only serves to reinforce its destructive logic. The neoliberal order has imposed itself by stealth in the past few decades, widening inequality in pursuit of corporate wealth. People are expected to adapt to what this model demands of them. Stress has been pathologised and privatised, and the burden of managing it outsourced to individuals. Hence the pedlars of mindfulness step in to save the day.
