About 1,200 kWh per transaction, currently[0]. I wrote about this back in 2022, when it was about 2,200 kWh per transaction[1]. Edit: made a chart with this data, but adding in a bitcoin transaction[2] [0]: https://digiconomist.n

The constant "By the way..." from Alexa drove me nuts. If you say "Alexa, stop by the way", it'll get the device to stop responding with follow-ups for ~24h. I ended up creating a routine that runs every night at 4a

I've been tickled by the idea of a follow-up version, Send Me To Hell, where users instead throw their phones _downward_. High scores are awarded based on the maximum speed achieved as the phone hits the ground.

EDIT: My reply below is wrong - you _can_ deal with in-flight requests with E-Tags as well using the if-match header. I had only seen them used with if-none-match. TIL. E-Tags would probably not help here, because the client won't have

The Common Paper app[1], though not quite a git workflow, has always struck me as being pretty close to how an software engineer might approach contracts: 1. An immutable set of standard terms, with variable references. 2. A collection of c

Betterment's Cash Reserve[1] might be of interest to you. It's a similar concept, where they spread your deposits among multiple program banks to give you a higher level of FDIC insurance. [1]: https://www.betterment.co

I managed to get my rocket very very slowly rotating (<0.1° / s), so that I could just hold the acceleration and have it do one arc from launch to crash: Unbelievable, the crater is visible from Earth Score: 1712.2 point

RoQR: https://roqr.app/ It's a privacy-focused dynamic QR code application. Just got my first paying customer this past week, which I'm pretty stoked about! The costs of running it are very low (~$15 / month)

I'm building an open-source[1] alternative to qr-code-generator (Bitly), called RoQR[2]. The goal is to provide advertisers with analytics for the scans of their QR codes while still being as privacy-respecting as possible to the scann

No, the calculation is done per transaction, not per block. You can calculate the per-block consumption pretty easily based on the stat that there are about 150[1] blocks mined daily and the total TWh used per year for the network is 200[2]
