I tried to sanity-test the math here running the same calculations on a 700 kg horse, of which around 50% mass is muscle.

700 kg x 50% = 350 kg

Low:

350 kg x 100 W/kg = 35,000 W

35,000 W / 746 ≈ 47 hp

High:

350 kg x 200 W/kg = 70,000 W

70,000 W / 746 ≈ 94 hp

Despite what the term "horsepower" would seem to suggest, a horse can actually output more than one horsepower. Estimates put peak output of a horse around 12-15 hp. By those numbers, even the low end estimate above is around 3-4x too high. We're gonna need more dogs.

As a Floridian, I have to use a VPN for that.

I'm hesitant to blame the celebrities on this one. Putting on a concert is a business proposition not just for the venue and ticketing (dis)service, but also for the performers. As with any business venture, the goal is to profit. Larger acts often have large set pieces to create and massive amounts of equipment to transport, not to mention all the labor that goes into setting up at each venue. Can't make the economics of that work if you don't have enough seats to sell, and Ticketmaster/LiveNation owns the lion's share of those large venues.

Look into microphone jammers

We have a one-car garage and two cars. I have a table saw, therefore we have a no-car garage.

Could be a gasoline/jet fuel powered drone, but still not energetic explosions.

As a result of the explosion, windows were broken in some houses but nobody was injured, PAP reported.

Defense Minister Wladyslaw Kosiniak-Kamysz later said the object was most likely a drone, adding that an analysis was underway to determine whether it was a military or smuggling one, PAP reported.

While I'm not an explosions expert, I would wager that a non-military drone likely wouldn't be carrying anything that explodes energetically enough to break windows. I suspect only an explosives-armed drone would do that.

As the article states, the distance between Italy and Sicily is around 2 miles (3 km), which makes this bridge unimpressive in terms of overall length, as there are hundreds of bridges longer than that. The article claims this would be the world's longest bridge, comparing it to Çanakkale 1915 Bridge, which isn't the world's longest bridge, but rather the bridge with the longest unsupported span at 2 km. There's no artist rendering of the proposed bridge, and no mention of whether Italy was planning to build this bridge in such a way that the main span would be over 2 km. This distinction means the difference between unremarkable, or modern engineering marvel.

I definitely interpreted this title as someone lighting a 110-year-old cigarette.

My first smart home purchase was a set of four Wemo light switches to be able to turn on all four of my backyard lights without walking around the house (wraparound backyard with a light switch in my bedroom, living room, dining room, and kitchen). They're still working nine years later, and as long as they still function locally with Home Assistant and don't make a fuss, I'll keep them in service. If they stop working or give me angry red lights, I'll throw in some Z Wave switches.
