throwaway_non Shared Cache Is Going Away

Can't we just show a "This site may harm your computer" message whenever a site is recording too much timing data? The page is justifiably considered malware at that point.

For example there's nothing preventing someone from timing all my keyboard events for keystroke biometrics: https://en.wikipedia.org/wiki/Keystroke_dynamics

throwaway_non The Misunderstood Roots of FRP

Won't your example trigger an infinite loop of celsius/fahrenheit conversions? Especially if the floating point value is slightly off.

I think your example is exactly why stuff like React won vs data-binding frameworks. With declarative programming, you just have a single source of truth that you change once (you can arbitrarily pick celsius or fahrenheit or even kelvin) and let the framework figure out what needs to be diff-ed in the derived views.

throwaway_non Cell and Molecular Biology Animated Textbooks

If you want something more accessible, I highly recommend the BBC documentary "The Hidden Life of the Cell": https://www.dailymotion.com/video/x6agslv

If this course is at the same level of production values, I would buy it just for entertainment purposes. It beats watching CGI explosions from movies! It looks like it's just $65 dollars for independent students. The samples look decent: https://www.smart-biology.com/life-unit-1-from-atoms-to-cell...

throwaway_non What costs are exponentially dropping?

Cost per GFLOPS: https://en.wikipedia.org/wiki/FLOPS#Hardware_costs

Probably the clearest chart that explains why machine learning is blowing up now, despite the fact that the same neural network architectures existed since 1990s (e.g., LeNet-5).

It's because cost dropped from $47,000 per GFLOPS to $0.02!!!

throwaway_non Text Editing Hates You Too

I once tried to customize a rich text editor to support SVG text effects (like https://www.smashingmagazine.com/2015/05/why-the-svg-filter-...) and damn near lost my mind.

If I had known that you can write an entire book on just text layout I wouldn't have bothered: https://www.oreilly.com/library/view/svg-text-layout/9781491...

throwaway_non Ask HN: What products or services do you wish existed for your startup?

On GCP, maybe firebase auth: https://firebase.google.com/docs/auth

throwaway_non Ask HN: What is the most beautiful piece of code you've ever read?

This is O(n^2) though
