Environment Canada assumes 60 km on their Weatheradio page ( https://www.canada.ca/en/environment-climate-change/services... ), so that's what I went with. Having said that, I very much agree that the range i

That was exactly my thought when reading the article and my personal experience with Covid. For a couple weeks, I perceived a persistent smell of something burning.

Golf courses in the USA used about 2.1 billion gallons of water per day circa 2004 [1]. In other words, the annual usage of Amazon's datacenters per the article, 7.7 billion gallons, is less than the amount of water used on just Americ

Goes back at least slightly before that, as I've had 2038epochalypse.com registered since March 2017, but I can't recall whether I thought I was being clever or whether I heard it somewhere else.

Ultra-fast rise-time pulse generators! Yeah, hardware -- or, hooray, hardware! A few months back, I got excited about pulse generators that had rise times on the order of 15 to 30 picoseconds. There aren't a lot of those available, and

Indeed. I've unsubscribed from all subreddits that have become infested with political content, and I've "unfollowed" all of my acquaintances on Facebook and LinkedIn who post anything political. So much more enjoyable.

Under $100: a Knipex pliers wrench. Best hand-tool ever! I originally got just the 7.25" size, but now I own everything from even shorter ones to much longer ones. I use them all of the time. If you're cheap, you can even get a kn

Unfortunately, that link between vagotomy and reduced risk of PD hasn't been supported by subsequent studies. In fact, it wasn't really even supported by the initial study[1]: although the point estimates of the hazard ratios were

On those days, I like to switch from work on the computer to work with my hands, like wrenching on a project in the garage. It won't get me any progress on my computer-based work, but it will give me a sense of progress on my garage-ba

While well-intentioned, I wonder if this will lead to something like the "sesame" debacle[1], in which is becomes far cheaper and easier for companies to deliberately design digital devices so as to be absolutely unrepairable -- e

Yup, self-employed embedded firmware and hardware engineer. I mostly consult on things like wearable sensors (especially class 2 and class 3 medical devices) and industrial control systems. I also have a bit of an odd niche in phosphorescen

Exactly this: my 96-year-old grandma still uses Wordpad to write letters that she then prints out and mails to the family -- just like she has been doing for almost 25 years. There's definitely a niche for Wordpad.
