Non technical

Mental speed is high until age 60 as revealed by analysis of over a million participants: response time is not mental speed! "Our results indicate that response time slowing begins as early as age 20, but this slowing was attributable to increases in decision caution and to slower non-decisional processes, rather than to differences in mental speed. Slowing of mental speed was observed only after approximately age 60." Go learn some math before your 60s.

The surprising afterlife of used hotel soap: "Soap is the most commonly used hotel ammentiy ... While some of us smuggle home every bar we can get our hands on (a totally acceptable move, according to hoteliers), most guests leave behind sizable, half-used hunks of soap." Great story telling, with excellent figures and pictures.

Be careful with that thing, it’s a confidential coffee maker "I love so much about this story. But mainly the irreverence all around."

Travel is best with young children: or how to travel like a children.

walker Why I Walk and How to Walk (12 miles a day)

Reminds me of On the Link Between Great Thinking and Obsessive Walking: "As a businesslike man, he would pile up a mound of flints at the turn of the path and knock one away every time he passed to ensure he made a predetermined number of circuits without having to interrupt his train of thought. Five turns around the path amounted to half a mile or so."

The feedback loop of shit: the feedback loop of real life. "As the scholarship money runs out, or the effects of living on a low income for years start to bite, people have to drop to part time study and take on more paid work. At the same time, people find they can’t keep putting off ‘life’ things, like having a baby. Some develop chronic health problems, which are made worse with the stress of an unfinished thesis lurking in the background."

103 Bits of Advice I Wish I Had Known

How to professionally say : collection of useful passive aggressive phrases, some are not that professionally passive, so use at your own discresion.

Guidelines on Writing a Philosophy Paper: "One of the best ways to check how well you understand that material is to try to explain it to someone who isn't already familiar with it. I've discovered time and again while teaching philosophy that I couldn't really explain properly some article or argument I thought I understood. This was because it was really more problematic or complicated than I had realized. You will have this same experience. "

How Retool upgraded our 4 TB main application PostgreSQL database: "standard" procedures ~~that not every company will take~~ to upgrade with minimal downtime, start with problem and expectations, narrow down to tools available, then implement solution carefully.

How I fell in love with low-js, along with http://youmightnotneedjs.com/ containing useful html components in pure html+css. I've written no more than 10k loc of Angular/React/Vue, but still have no idea how they work together, and I thought frontend developing skill would really be helpful..

Modern Python performance considerations: "Python 3.11 is up to 10-60% faster than Python 3.10. On average, we measured a 1.22x speedup on the standard benchmark suite."

The best engineering interview question I’ve ever gotten, Part 1: Can you add a new feature to a project you never worked on under 3 hours? How will you do it? The project and feature are carefully chosen to avoid requiring specific domain knowledge.

How to Freaking Find Great Developers By Having Them Read Code Another post about interview, I've recently finished a code review round, the experience was quite relevant:

  • the pull request was persumably from a junior engineer: not the only engineers to over-complicate implementations in real life though
  • intentionally crafted bugs on language features: I don't like this because it's hard to define necessary knowledge scope about specific programming language
  • intentionally crafted bugs on implementation: requires me to mentally compile the code and verify correctness since there are no test cases, luckily these bugs are easy to spot
  • code style: test cases, variable naming, language conventions
