I suppose this might be useful for making full-auto coffee machines that can self-adjust parameters like grind size, water:coffee ratio, tamping strength (for espresso style machines) etc. Although there's plenty of things to measure already, they don't really directly check correct brewing. This could help improve a lot.
Cars are the most familiar to the everyday user, which is why it's the most common in perception. It's also actually one of the easier ones to solve (ie it's basically done).
Trucking is technically not to hard but logistically difficult. Aviation is extremely technically challenging. Shipping is economically difficult. Electricity generation has lots of factors, there's a lot of generation that can and has been changed easily, but some generation which is harder to switch.
If you get outside of oil into CO2 generally, there's even thornier issues. Concrete production, for example.
There's no allegation that these workers abused their access. The allegation is that their routine work reviewing footage included private content. The revelation is that USERS are using meta glasses non-consensually.
You don’t actually need a VIN on a car, you just won’t be able to register and drive a VINless car on public roads.
Some states seem to have designated even private roads as “public” if there is uncontrolled access (seems ripe for a court challenge though). But offroading or gated roads would be fine even here.
Some YouTubers have fun importing cheap Chinese cars that aren’t street legal and destroying them with extreme offroading.
> You don’t actually need a VIN on a car, you just won’t be able to register and drive a VINless car on public roads.
Somehow I doubt that many 2nd amendment supporters would be okay with "You don't need a registration number on your gun, it'll just be illegal to carry/use it anywhere except private property"
Some would, some wouldn’t. There are some who only care about home defense or sport shooting on private land. Open carry and CCW folks would be quite upset, yes.
The biggest problem with this (for the first group) would be conveyance from buyer to seller or to/from a range or hunting grounds.
FWIW: this isn't a universally-applicable statement, plenty of states forbid DWI during any and all operation of motor vehicles, including on private property.
I think in almost all states DUI applies to private roads accessible to the public, such as parking lots and driveways. Mythbusters drove drunk on a closed course in California and that was legal.
Only a few states absolutely forbid operating a motor vehicle while intoxicated (I know Washington is one). That said, you’d have to do something pretty absurd to attract the attention of law enforcement if you’re staying on your own land.
Do F1 cars have VINs? I’m pretty sure you don’t need a VIN on a car if it stays off public roads. Also driving is not a right enshrined by the constitution.
Tell me you have never actually read the statute without telling me.
Per the statute text, you may not manufacture a firearm for personal use in Colorado: the statute requires an FFL's license number (which you do not have) to be placed in the serial number string.
FFLs didn't exist in 1790 - therefore this fails Bruen among other standards.
That fact check says Sheikh Mohammed bin Rashid al-Maktoum didn't say it, but does say it is also attributed to Sheikh Rashid bin Saeed Al Maktoum, and doesn't debunk that --- which is what the comment you are responding to claimed.
Low earth orbit satellites orbit about once per 90 minutes, so in 10 minutes they go about 40 degrees across the sky. The comet is not even orbiting the earth, it's essentially fixed in the sky. The earth only rotates about 2.5 degrees in 10 minutes. So the satellites streak is 16 times longer than the comets.
Let's start with "fixed in the sky" and qualify your frame of reference as the field of distant stars, or the celestial sphere. The common coordinate system is right ascension (RA) and declination (dec).
The GP question was about the Earth's rotation, which would be in terms of azimuth and altitude, and that question's been asked and answered. The key terms there: "equatorial mount" and "clock drive".
The comet C/2025 R3 (PanSTARRS) is in fact near its highest velocity (with reference to the Sun especially), being near perihelion while this photograph was taken. The comet is swinging around the Sun, and it was about 0.49 AU from Earth at the time of the photograph.
I chose an approximate time on April 27: in 10 minutes of wall-clock time, with the J2000 epoch, the comet's apparent motion is from RA 02h 49m 07.1s, dec +06° 02' 56.5" to RA 02h 49m 15.4s, dec +06° 02' 13.3"
That is a distance of 2' 11.13" across the celestial sphere. For reference, Venus is 11.6" wide in the sky as we see it this week.
24 hours later, we find it at RA 3h 08m 44.1s, dec +04° 19' 27.8". Its apparent motion was 5° 10' 46.02", which is approximately the width of your three middle fingers held together, at arm's length.
So, "fixed in the sky" is not a scientifically useful description of astronomical objects: we need to put that in terms of at least one frame of reference, and "apparent motion" which is how an observer perceives it.
Given that the moon is about 0.5 degrees in diameter from Earth, shouldn't we expect to see the stars and comet much more blurred than they are here though? Or the ground if it's stabilized against the rotation?
Unions aren't really there for customer service. Nonetheless, there's often times where the worker demand benefit customers too: Nurses fight for better nurse:patient ratios, benefiting patients too; teachers fight for the resources for them to teach well; starbucks baristas fight for a work pace that allows them to actually engage customers like the brand used to offer. etc
Especially flying with kids at naptime or bedtime. Trying to get an extremely tired toddler to fall asleep on a plane just to hear an announcement about in flight entertainment. OMG.
