I might have agreed with you if Apple was a good gardener. That would involve weeding out the scams in the app store, giving developers feedback on radars, and being more communicative and reasonable in app review.

The placement of punctuation is the reason I believe Dvorak is better than most other optimized layouts. They may be optimal for their metrics, but their metrics are bad. I have been thinking about trying a one-handed layout lately, the one

From the article the difference doesn’t seem that huge: Stockholm - 0.8 unicorns per 100,000 Silicon Valley - 1.4 unicorns per 100,000

I think I'm almost as uninformed as you, but I believe it comes down to the difference between perfect solutions and close enough solutions. Consider the classic NP problem of the traveling salesman problem. "[Modern heuristic and

I did not participate in the project, and I agree the seed is almost worthless to the world but I don't think the project was a waste of anything. The minute inherent value of the answer is not why it was done. Finding the answer becam

I'd be interested to see your calculations, because I'm just doing it according to the book, blindly following Friis transmission equation. It sounds like you are applying more physics based thinking to the problem. I have no clue

Those are not my words, they're all from my professor and this [1] book, chapter 23. With remote control and immediate feedback I'm talking about closed loop control. Consider industrial automation with image processing done remot

Keep in mind you can increase the energy per bit by increasing symbol duration. I had a problem like this on my wireless systems exam recently, where the setup was two Arecibo style antennas with a reasonable 20ly distance, a low 48bps, an

5G is not mainly for consumers like you and me. We are not willing to pay significantly more for the faster speeds, most people are plenty happy with 4G. The big difference with the 4G to 5G transition compared to the previous transitions i

After the field of straw men and bad made up definitions the author does actually arrive at something resembling that conclusion. > There is no single thing named "electricity." We must accept the fact that, while several diffe

I took note of that part too, it reminds me of this article [1] posted on HN recently. It contrasts the fleeting and context dependent flows of posts on social media ("the stream") with enduring wiki style interlinking of posts wh
