The fifth hyperfactorial: 5⁵×4⁴×3³×2²×1¹=86400000 milliseconds is exactly 1 day 8 years ago

I feel like I was just nerd sniped, but this drove me crazy until I thought about it for a bit.

If we treat Earth's orbit as a perfect circle, then the number of milliseconds in a year would be its circumference. To get to pi then, we just need to divide that by its diameter or 2*its radius. In addition, we have the circumference in ms so we want to convert that into a distance or the radius into ms so we need the speed the Earth is rotating around the sun.

The average radius of the Earth to the Sun is 149,600,000 km so the diameter is 299,200,000 km. Earth's average orbital speed is 30 km/s or 0.03 km/ms. Combining these two numbers to get ms, (299,200,000 km / 0.03 km/ms) = 9,973,333,333.333 ms, which is very nearly 10 billion.

Ask HN: What simple tools or products are you most proud of making? 10 years ago

I still use http://seductiveequations.com/2015/11/09/water-meter.html rather often to casually see how much water I've been using. Helped me to discover when a new water timer I installed outside got stuck open. Similarly, I've been able to see through actual data how much water my new low-flow showerhead just saved me right after I step out of the shower. Wish I had more time to improve it, but despite that, it's still remained quite useful.

To Fall in Love with Anyone, Do This 11 years ago

Found this kind of interesting, but I'm having a hard time understanding the procedure. Do both people ask each other every question or does person A ask question 1, person B asks question 2, and so on and so forth?

Am I just misreading this or completely uninformed on something, but since when is Wordpress extremely new?

In your child comment, you say "I can see it replacing newer languages like nodeJS, Go and PERL in the future. In the next couple years people will start realizing that the consistency, speed and security offset the lack of communities using it, and I can see it becoming really popular."

Again, I feel like I'm in a time warp, but when have those three things been qualities of PHP? Also, PHP has been huge for years. Node.JS and Go have only recently been taking over.

I'm so confused…

Earnest question then: what do you see as the bleeding edge of technology? Where is that happening? What companies are doing it?

Show HN: Where is “Who is hiring?” hiring? 11 years ago

I'm surprised nobody else has requested this, but any chance for a state category? If you really want to impress me, perhaps a warm and cold climate section or maybe have to shovel snow vs. unlikely to shovel snow. :P Gotta set my priorities straight…

I just wanted to say, you're awesome. I've long been trying to find something similar or some easy way to keep up on upcoming conferences. Thank you!

Tado Cooling – Intelligent AC control 12 years ago

You mention this magical whole house fan multiple times across your responses, but how exactly would a fan help those of us living where it's 70-80 F at night? I have one and besides being obnoxiously loud, on one of the aforementioned nights, it'd simply end up blowing around that hot, humid air without actually cooling anything.
