crehn··on The Matrix Is Unreal
The article seems to suggest that's all real-time rendering though?
crehn··on YouTube deleting comments who criticize their hiding of the dislike count
Or make a bot that leaves a "like this to dislike the video" comment on videos.
crehn··on The slowest SR-71 Blackbird fly-by
To be honest it's cringy even reading for the first time.
crehn··on Novel mind-body program outperforms other treatments for chronic back pain
TL;DR:

> Psychophysiologic Symptom Relief Therapy (PSRT) is designed to address underlying stressors and psychological contributors to persistent pain as well as conditioned pain responses and fear avoidant behaviors.

Good to see research into this. I've definitely had enduring pain relief by a deeper change in mindset.

crehn··on Octopuses, crabs and lobsters to be recognised as sentient beings under UK law
> their observations of their behavior over a history of catching and eating them

Perhaps "data" is too analytical; I'm interested in how plants convey pain and fear.

crehn··on Octopuses, crabs and lobsters to be recognised as sentient beings under UK law
> they experience pain and fear, like [...] probably also many plants

Out of curiosity, do you have any data to share that supports your perspective?

crehn··on Monte Carlo Methods or Why It's a Bad Idea to Go to the Casino
Put a large sum on black in roulette. If you lose, place double on black. Repeat until you win once or end up bankrupt, then go home.
crehn··on Show HN: Windows 2000 on Docker
Why not? It’s fun.
crehn··on Life is too short to depend on unstable software
The point is well-designed contracts don't need many breaking changes in the first place.

As a corollary, badly designed software are more likely to require breaking changes.

Same applies to badly managed software, where compatibility is broken inconsiderately, wasting people's time.

crehn··on Faced with soaring Ds and Fs, schools are ditching the old way of grading
Regardless of the "workplace", I think what it really means is an aptitude to be productive despite ambiguity and less-than-ideal conditions. Those skills apply everywhere.
crehn··on ASCII Video Player
Couldn't get it to work on Safari. Just a blank screen, but audio works.
crehn··on AirCover by Airbnb
What if I'm the guest?
crehn··on AirCover by Airbnb
So what would happen in practice if I completely trashed an Airbnb for $1M's worth?
crehn··on The brain can recall and reawaken past immune responses
Placebo is such an interesting phenomenon. I had a certain physical pain difficult to describe that I could’ve sworn to have felt, but after addressing my perspective I’ve no longer had any such symptoms. Not sure if related, but I still don’t understand it.
crehn··on Segmentors vs Integrators: Google’s work-life-balance research
The latter!
crehn··on Segmentors vs Integrators: Google’s work-life-balance research
I live in a 1-bedroom apartment, and things that have allowed me to segment much more efficiently, is (1) always writing down goals for the next day/week before stopping work, (2) putting my work computer and notes on a shelf out of sight at the end of the day, and (3) making small adjustments to my desk (e.g. rotate it 90 degrees) to make it feel different after work.

This on top of dealing with my personal struggles head-on has overall made me much happier, and I’d say more efficient.

crehn··on Spiders are much smarter than you think
I couldn’t care less whether the spider is dangerous or not.

It’s more the erratic, jittery movements of spiders and their multitude of fast legs that’s off-putting.

Especially when you’re taking a dump in a dimly-lit outdoor toilet and notice there’s a hand-sized huntsman spider a few inches from your knees. I have never sprinted so fast.

crehn··on Ask HN: Why does my cup move by itself?
That seems to make sense! I assume the delay between each movement is due to the time it takes for the air to expand again enough to forcefully escape from the side of least resistance (where the counter is ever so slightly higher).
crehn··on Ask HN: Why does my cup move by itself?
Wouldn't that cause it to move in a single continuous movement? Instead of the 3-4 little movements in the video.
crehn··on Roblox has been down for days and it’s not because of Chipotle
That's in fact how most high-impact events should be handled: mitigate the issue with a potentially short-term solution, once things are back up find the root cause, fix the root cause, and perform a thorough analysis of events to ensure it won't happen again.

If it's a known issue, is there no way to increase the transaction ID size?

Quite surprising a seemingly battle-tested database can choke in such a manner.

crehn··on Ask HN: If the Internet were redesigned today, what changes would you make?
What about the security aspects of NAT?

e.g. Isolating subnets and restricting outbound access. Seems like a useful defence-in-depth mechanism in case of misconfigured firewall rules.

crehn··on Publish your PWA to the iOS App Store
> Progressive Web Apps (PWAs) are web apps that use service workers, manifests, and other web-platform features in combination with progressive enhancement to give users an experience on par with native apps.
crehn··on Debian's Which Hunt
It's minimal effort to maximize compatibility and consistency, regardless of where the script may be run.

Shell scripts can run in a myriad of hosts, from VMs to stripped-down containers. When writing robust production code (not to say that shell scripts are ideal for that purpose), you'll want to minimize moving parts and risk surface, so that you can go home more confident that things will just work regardless of what you throw at it.

crehn··on NPM package ‘ua-parser-JS’ with more than 7M weekly download is compromised
The JavaScript culture around dependencies is baffling to me.

The simplest of tools will easily have hundreds of transitive dependencies, making these sort of events a mess to deal with, and causing the blast radius to be avoidably large.

crehn··on A Short Cautionary Tale About Refactoring
To the downvoters: why? Genuinely curious.
crehn··on Tell HN: Thank You Dang
HN is insane in a good way. You'll find so many people from various background with the most esoteric hobbies and interests. I love this community.

Thanks dang for helping us keep the signal-to-noise ratio high throughout the years!

crehn··on I spent eleven years working on this Line Rider track
I do believe it is to some degree jealousy. Everybody understands the scarcity and power of passion; what’s work for some is love for others. When you compound a lack of passion, insecurity and bad human character, it’s not surprising to have reactions similar to purplecats’ above.
crehn··on Taking screenshots isn't allowed by the app after upgrading to Android 11
They’re mutually exclusive; I’m sure GP meant it in a pragmatic sense.
crehn··on Taking screenshots isn't allowed by the app after upgrading to Android 11
Is there any situation on iOS where a screenshot cannot be taken? (serious question)
