Because the IR light is turned on and off at that frequency.

The cheaper sensors detect volatile organic compounds, and assume that CO2 level correlates with that. This isn't necessarily true. BigClive tested one, and called it a party detector[0], because it was great at picking up alcohol, but

A combination. The reason the CO2 absorbs that particular wavelength of IR light is deeply bound in quantum processes. But the reason they hum is simply a classic heat effect.

Can someone ELI5 why this is different from Penrose tiling?

by mnw21cam 4y ago
While that looks like a very nice chip, it still doesn't have ethernet or non-volatile storage, so it doesn't help with remote access or logging.

The power available in a RasPi is way overkill for "give my plants half a cup of water every day" projects too. I don't need four cores and dual HDMI outputs to tell a motor to spin for half a minute once a day. I'm just

DNT may be opt-out. But it should certainly be treated as "Don't even bother asking for consent to track, because I already told you the answer is no, and you'll be harrassing me by asking."

My wife will insist that one cup of tea I bring her is amazing, but another one is disgusting. However, they're all from the same box of teabags, made the same way, and the biggest correlation as far as I can tell is how long she has l

Yeah, he tripped and threw the curry he was trying to serve over my wife's shoes. It's all she talks about whenever she sees him on TV.

I certainly remember a reasonable stretch of time where the advice was that the Linux kernel would not compile correctly with the latest gcc with optimisations on, and you should use the known good version of gcc instead.

I bought one of the first versions of those shiny Seagate SMR drives, specifically to store my (encrypted) backups. It failed after a couple of months, so I returned it and got a replacement. Which failed after a couple of months. So I join

Does anyone else find it a little strange that the logo for Ubuntu is used in the download section against the Linux version, instead of Tux?

It isn't the voltage that causes interference, it's the current. A flowing current creates a magnetic field which can induce a voltage in nearby wires that run parallel. It just happens to be that the wires that carry the highest

Two things. Firstly, I don't think any conclusions can be made about whether dd or dd-rescue is more susceptible to bit flips. It could be that both allocated a buffer, and dd-rescue just happened to be handed the area of memory with t

I correctly received a similarly-addressed letter, and was fairly impressed that it made its way to me.

While I didn't like the start/stop feature when I had a hire car briefly, I can't see how it would ever add a lag. By the time you have pressed the clutch pedal down to put it in gear, it has started.

Yes, that's how I do it. I have a script that takes a list of cuts, source videos/images, and effects, and runs ffmpeg to produce the final result. That's also how many GUI video editing tools work - they just use the GUI to

I had a case recently where a company recommended that I kick off a credit card dispute. But it was because the company was calling in the administrators, and therefore they wouldn't have any reputation or assets very soon anyway.

V_r is almost always above V_1, which is the decision speed. If you're going to abort a takeoff, that decision needs to be made before V_1, otherwise you're likely to overrun the end of the runway. So, once you get to the stage wh

Fragile X is about 1.4 cases per 10,000 males. Autism is way more common than that, so I wouldn't say the Fragile X accounts for even a single percent of Autism cases. The article saying that it is the most common cause of Autism is

The exact location of the moon in the sky depends to a very small extent on your location on the earth's surface. The tweet says near Brighton, and that's already accurate enough to tell the direction of the moon much more accur

There's a moon in that video. That'll give you the angle more accurately than a building.

So once this is enacted, I get to call the police next time I see an advert for P&O Ferries. Sensible.
