I'm looking at a bottle of Advil right now and nowhere does it mention not to take it on an empty stomach.

mark_kalvelageon Post Virtual Reality Sadness

"That’s what I love about this place, all the secrets, all the little things I never noticed even after all these years. You know why this beats the real world, Lawrence? Real world is just chaos. It’s an accident. But in here, every detail adds up to something."

mark_kalvelageon Nintendo’s method of making games [video]

Yes, Nintendo games and games from a few other developers are probably the most pleasant pieces of software that I've ever used: well-designed interfaces, low-latency interaction, very few bugs, and tons of attention to detail.

I wish there was more information out there about Nintendo's software development process.

I think one of the big reasons that many dev tools are command line programs is that command line interfaces are just easier to code, even if you are writing all the parsing logic from scratch. You don't have to worry about designing a layout, hooking logic up across a UI thread, wrestling with a widget library, etc.

mark_kalvelageon The bizarre role reversal of Apple and Microsoft

Last year I bought a new Macbook Air that came with Yosemite, so after I got home and went through the setup process, I tried to update it to El Capitan through the app store. The laptop went to reboot... and didn't come back up. I thought it was completely bricked because pressing the power button did nothing: no LED light, no startup chime. Apple support guides said to hold down the power button for ten seconds and then re-press it, which at least made the laptop turn on and chime, but nothing happened beyond that. Booting into recovery mode didn't work, but luckily booting into internet recovery mode did. I had to reinstall Yosemite over the internet, create a USB image of El Capitan, then install from the USB.

Even after that, things never went smoothly. There was some sort of bug where I couldn't enter my Apple ID security answers in the OS dialog box. Like you, I had problems with external displays, especially with waking up a display when the laptop itself woke up. The very first time I tried to restore from a Time Machine backup I got errors. Problems with iTunes and Photos sync. Not to mention more or less subjective issues I had.

I had more problems with this laptop than I've had with any Windows machine.

You need to read gwern's link more closely. Second paragraph:
