If a payment processor suspects a business is laundering money, they can hold the funds, but it's illegal for the payment processor to tell the business that they suspect money laundering. So they end up saying something like "we&

I haven't found this to be a problem in practice. I have two USB-C laptops -- a ThinkPad T480s and a MacBook -- and both of them work fine with my USB-C dock, and with each others' chargers. That's all I need.

Nice! Yeah, mCaptcha looks like just what I had in mind. I wonder why this approach hasn't been widely adopted?

I wonder if proof-of-work would help. Suppose every form submission requires an expensive calculation, calibrated to take about 1 second on a typical modern computer/smartphone. For human users, this happens in the background, although

I love this! Will it be possible to plot historical events on the map? I'd love to see e.g. a month-by-month combined timeline+map of Napoleon's invasion of Russia, or the D-Day invasion. It would also be neat to be able to link a

Shadowstats's 80s-based measure says we've been having 10% YoY inflation for two decades now. If that were true, prices would've 5x'ed since the year 2000. That doesn't pass the 'sniff test' to me; e.g. th

Suppose you have a newsletter with 10,000 subscribers. You need to perform a proof-of-work the first time you send an email to each new subscriber; so, 10,000 proofs-of-work. Each proof-of-work costs $0.001. This adds up to a grand total of

The article notes that the LED "acts as a very low temperature object". I interpret this to mean "the LED radiates as though its temperature is lower", rather than "the LED radiates as though its emissivity is lower

True, but the distinction is irrelevant in this case.

(Disclaimer: I have some background in physics, but I'm not an expert.) I think the heat is transferred from the "computer" to the LED itself. So the LED itself heats up. To go into a bit more detail: All physical objects emi
