The whole incident emphasizes the extent to which these ostensibly technical debates are often settled by personality and emotion, rather than by technical excellence. //

It looks likely that Overstreet has upset too many important, influential people, and hurt too many feelings — and as a result, Linux is not going to get a new next-gen copy-on-write filesystem. It's a significant technological loss, and it's all down to people not getting along, rather than the shared desire to create a better OS. ®

To check the CPU temperature on FreeBSD, you can use the command sysctl -a | grep temperature after loading the appropriate driver for your CPU type with kldload coretemp for Intel or kldload amdtemp for AMD processors. Make sure to add the driver to /boot/loader.conf for automatic loading at boot time.

These parasites are usually found in the skin, but they can invade anything.

Most people would recognize the device in the image above, although they probably wouldn't know it by its formal name: the Crookes radiometer. As its name implies, placing the radiometer in light produces a measurable change: the blades start spinning. //

It's quite common—and quite wrong—to see explanations of the Crookes radiometer that involve radiation pressure. Supposedly, the dark sides of the blades absorb more photons, each of which carries a tiny bit of momentum, giving the dark side of the blades a consistent push. The problem with this explanation is that photons are bouncing off the silvery side, which imparts even more momentum. If the device were spinning due to radiation pressure, it would be turning in the opposite direction than it actually does.

An excess of the absorbed photons on the dark side is key to understanding how it works, though. Photophoresis operates through the temperature difference that develops between the warm, light-absorbing dark side of the blade and the cooler silvered side. //

But a Crookes radiometer is in a sealed glass container with a far lower air pressure. This allows the gas molecules to speed off much farther from the dark surface of the blade before they run into anything, creating an area of somewhat lower pressure at its surface. That causes gas near the surface of the shiny side to rush around and fill this lower-pressure area, imparting the force that starts the blades turning.

Just who are the greatest aerospace engineers of all time? The ability to fly has long been an ambitious quest for mankind. Many centuries have been spent trying to master the art, as such there have been many aerospace engineers with a profound and lasting impact. Here at MNB Precision we have compiled a list of both the greatest engineers and the greatest aerospace engineers. Ranging from the most famous and prominent to some lesser known yet still crucial figures, these are some of the best professionals in the field.

having spent several days behind the wheel, I can report it might just be one of the best-driving, too. //

This is not just one of Porsche's existing flat-six engines with an electric motor bolted on; it's an all-new 3.6 L engine designed to comply with new European legislation that no longer lets automakers rich out a fuel mixture under high load to improve engine cooling. Instead, the engine has to maintain the same 14.7:1 stoichiometric air-to-fuel ratio (also known as lambda = 1) across the entire operating range, thus allowing the car's catalytic converters to work most efficiently. //

for the first time in several decades, there's now only a single turbocharger. Normally, a larger-capacity engine and a single big turbo should be a recipe for plenty of lag, versus a smaller displacement and a turbocharger for each cylinder bank, as the former has larger components with more mass that needs to be moved.

That's where one of the two electric motors comes in. This one is found between the compressor and the turbine wheel, and it's only capable of 15 hp (11 kW), but it uses that to spin the turbine up to 120,000 rpm, hitting peak boost in 0.8 seconds. For comparison, the twin turbos you find in the current 3.0 L 911s take three times as long. Since the turbine is electrically controlled and the electric motor can regulate boost pressure, there's no need for a wastegate.

The electrically powered turbocharger is essentially the same as the MGU-H used in Formula 1, as it can drive the turbine and also regenerate energy to the car's traction battery. //

Thank you @LarryOConnor and @bethanyshondark for having me on @WMALDC to talk about how DC crime has impacted me personally.

Let's just say that there are some pockets being filled, and they are not yours or mine. Kerry called climate change a gold mine for investors, and he sure has been right.

The steps below aim to illustrate how to setup a site to site VPN between two Mikrotik devices using WireGuard. Pre-existing local networks and firewalls exist on both R1 and R2. Between R1 and R2 the WireGuard tunnel will use 172.17.0.0/30. R2 has 172.17.0.1 assigned to its WireGuard interface, while R1 has 172.17.0.2 assigned to its WireGuard interface. The network used, or the order in which IP addresses are assigned is not important, however it is considered best practice to use a point to point subnet between peers.

Site to Site WireGuard tunnel
Consider setup as illustrated below. Two remote office routers are connected to the internet and office workstations are behind NAT. Each office has its own local subnet, 10.1.202.0/24 for Office1 and 10.1.101.0/24 for Office2. Both remote offices need secure tunnels to local networks behind routers.

According to the BBC's Future Planet, a cruising Boeing 747 burns through 0.9 gallons (4 liters) of fuel each second. This is equivalent to 3,500 gallons (13,250 liters) of fuel every hour. If a 747 is cruising at its standard cruising speed of around 580 mph (933 km/h), it is covering a mile every 6.2 seconds. Covering a mile requires 5.9 gallons of fuel. As a result, a cruising Boeing 747 can achieve just 0.18 miles per gallon.

However, this is not the full picture, as a 747 carries far more people. SeatGuru writes that Qantas Airways' 747-400 aircraft carry 364 passengers across Business, Premium Economy, and Economy classes. If we extrapolate this number of seats into the mpg that each passenger has, the data shows 65.5 mpg per passenger. According to calculatormpg.co.uk, the baseline for a good car mpg is 50. If a car is carrying two people, then the car is achieving 100 miles per gallon for each person. This suggests that flying on a 747 still uses substantially more fuel than a car carrying multiple people, but less than a car carrying one person.
