I found that there's a surprising difference in quality for what feels like it should be a commodity item. All the outlets in my newish build were tamper-resistant, and pretty much…

This is not a dissimilar system to Teletext[1], which transmitted data in the blanking interval of a broadcast TV signal, and could be interpreted by a TV or other hardware with ap…

I can't speak to the cloud provider support, as I don't use it, but they have supported scheduled backups since at least June 2019, as I have locally-stored backups from scheduled …

There were also several others, including some live shows, all of which can be found on the BBC's Computer Literacy Project Archive: https://clp.bbcrewind.co.uk/ During one of the …

I think the speed that things can go wrong when using a table saw (or most power tools) is faster than some people, including some woodworkers, might expect. There's a good example…

Churchill was also prime minister from 1951-55.

As a counter-example, I haven't had an entirely successful Google Takeout export in at least a couple of years, using their service to schedule the exports automatically every two …

This is true, but I don't think any consumer-grade sensor systems offer this as an option? I guess it might be useful if you're building your own sensor, and can't afford/justify a…

That's a shame, they've worked well for me. Unfortunately I can't recommend any others without doing some research, I found quite a few dual-NDIR sensor modules when I was looking …

The auto-calibration systems on cheaper consumer sensors also cause issues if they rarely see air that has low CO2 levels. Because these sensors can't measure absolute CO2 levels, …

Out of the three vaccines in use in both Canada and Europe, it appears that Canada entered agreements as follows: Moderna: August 5th, 2020 [1] Pfizer: August 5th, 2020 [1] AstraZe…

From the second paper[0]: 'In order to provide more information about event severity within the S1 designation, S1 severity events have been separated into two columns in Table 1 b…

They're using the ISO 26262 scale for severity, not their own: https://en.wikipedia.org/wiki/ISO_26262#Part_9:_Automotive_S...

Another interesting example is Hyder, Alaska, which is only accessible by road from BC, Canada. It relies on various services from Canada, including ambulance and fire services, th…

As a counter-example, I requested mine about 20 minutes ago, received an e-mail confirming the request, received another e-mail 6 minutes later to say it was available for download…

From the location of those light sources, I suspect they are from drilling rigs extracting oil from several large oil fields around the Grand Banks of Newfoundland. There's a map o…

If you're simply looking for capacitive touch in a consumer environment, then there are a great many. Simple capacitive touch sensors to replace physical push-buttons were widely s…

If yours also claim to be manufactured by American Paper Optics, as the pair in the parent comment claim to be, the (real) manufacturer has some information to help determine if th…

Many libraries have received glasses for free from the Space Science Institute, which is a reputable organisation funded by NASA, the National Science Foundation, and others. There…

This isn't limited to glasses. I purchased a 12x12 sheet of solar filter film from a seller on Amazon, manufactured by Thousand Oaks Optical (who are listed on the American Astrono…

As an example, the Vestas V164-8MW seems to be one of the largest off-shore wind turbines, and has a rotor diameter of 164m and a rotational speed of between 4.8 and 12.1rpm. [1] U…

I had the same issue with the seat edge, I believe that it's referred to as a waterfall edge. The rest of the chair was great, but I found that extremely uncomfortable after a few …
