There are many contributing factors:

1. LED headlights with an auto-dim function (i.e. they are on full beam until traffic is detected) that triggers too late or not at all. e.g. Teslas do this: when one overtakes me, I get blasted with full-beam in my mirrors when there's no car in front of the Tesla.

2. Headlights in tiny packages so that all that light comes from a tiny area: more light per cm2 is more unpleasant to look at.

3. Any headlights with a sharp demarcation of the beam. When a bump in the road changes the angle slightly, you go from the dimmed portion of the beam to the full intensity portion of the beam immediately instead of there being a gradual increase.

These are new factors brought on by headlight designs newer than halogen.
Halogen headlights are affected by:

4. incorrect installation of the bulb: a H4 halogen bulb has two tabs that are supposed to enforce correct orientation. Many people don't clock the bulb correctly, and then those tabs force the bulb to be at an angle.

5. non-functioning automatic headlight adjustment, or people forgetting to do that manually when the car is heavily loaded.

Mine lasted 35 years.

The JHUAPL mission goal is to study the interstellar medium, which it can reach in 10-12 years at 7 AU/y.

The Dwingeloo telescope was the largest in the world when it was built in 1955. It held that title until Jodrell Bank came online in 1957.

After World War II, Dutch astronomers led by Jan Oort got hold of a German Wurzburg Riese radar antenna, and repurposed it for radio astronomy. In 1951, they managed to detect hydrogen radio emissions at the 21 cm wavelength. They used this telescope to map the hydrogen in the Milky Way, creating the first map of our galaxy.

This success led to money being made available for a purpose-built radio telescope at Dwingeloo, one of the first in the world.

The telescope dish is covered in a wire mesh, which gave it the nickname 'chicken wire telescope'. This size of this mesh limits the wavelengths it can observe at.

They're already past the floor, or where the floor was initially thought to be. A few years ago, they started to switch off heaters on the instruments that were still in operation. To the team's surprise, the instruments continued to work, despite being 60Â C colder than they were designed for.

They've removed voltage regulators from the circuit. This gave them another few W of margin.

There are a few ways the mission can end:
1. Power drops until the RTG can no longer power a single instrument. This will happen within 5 years. Once that happens, Voyager can still transmit engineering telemetry, until power drops to below the level needed to power the transmitter. I've looked into this but was unable to determine if the transmitter can operate at lower power levels. Two power levels have been defined: 12 W and 18 W.

2. Thruster failure. Every day, Voyager uses its thrusters to keep its antenna pointed at Earth. The propellant lines are slowly getting clogged, and some of the lines are now more than 99% clogged. They recently switched to the least clogged set of thrusters.

3. Catastrophic failure. We came near this with Voyager 1 this year, when a memory chip in the Flight Data Subsystem failed and took out most of its program code. Both Voyagers have lost redundancy in some of their systems, and are one failure away from death.

More modern processors have survived for decades: Cassini, launched in 1997, operated for 19 years until its fuel ran out.

Today's radiation-hardened processors are built using much larger feature sizes than consumer processors, and are being used for decades in Earth's van Allen belts, which have far higher radiation levels than the surrounding space.

We started doing that right after Voyager: Galileo and Cassini were built specifically to answer the questions about Jupiter and Saturn that the Voyager data raised.
Orbiters for Uranus and Neptune are being studied at the moment; they have only recently become feasible thanks to advances in reducing launch cost.

JHUAPL has done a study for an interstellar mission which uses current technology only to get a spacecraft up to a speed of 7 AU per year, or twice the speed of the Voyagers.

The seat is the wrong place for bags.

Low wages, duh.

By the "true flatness of the Earth", you mean the curvature caused by Earth being a spheroid with a diameter of 12,700 km, right?

yeah, this happened on a system with AdBlockPlus installed instead of uBlock. Time to migrate, perhaps.

in Firefox with uBlock Origin, I got a prompt that I had an ad-blocker installed. I clicked Cancel, and the page loaded normally, without ads.

On another computer I whitelisted html-load.com, and got ./ pages with ads.

I have the 'Ads disabled' checkbox checked. Until 2 days ago, this was sufficient to keep the Slashdot home page free of ads.

2 days ago, the homepage stopped loading for me. I had to set NoScript to allow scripts from html-load.com to load, in order to see the homepage.
With this change, ads started to be displayed on every Slashdot page.

Trump's plans are for making the government less capable, and more aligned with the whim of current politics. Think what political appointees will do to the running of e.g. the EPA. Research destroyed, enforcement of environmental laws sabotaged by defunding the people responsible for that enforcement, etc.
