TIL the TCP packet checksum is only 16 bits long, so a randomly corrupted packet still has a 1 in 65536 chance of going undetected.
The good thing is that the lower level networking layers probably also have checksumming. For example, ethernet (as commonly deployed) has a 32-bit CRC.

@boomzilla The article does have a strong opening:
On September 15, 1896, two locomotives crashed head on 14 miles north of Waco, Texas. The locomotives’ boilers exploded on impact, sending debris flying through the air for hundreds of yards, killing at least two spectators and maiming countless others. One man even lost an eye to a flying bolt.
Well worth reading.
Indeed. Had I not read it, I would have missed this:
Me and my family got to see 4014 up close. My dad and brother had been following the work and had seen it pull out of the steam shop for the first time. We went to UP's spike ceremony the day before Spike150 (as well as the event at Promontory Summit itself) and chased it a bit the first day of trip back to Cheyenne. It's a very impressive machine.
Coming up to that weekend, my family and I were traveling and stopped for the night in Cheyenne. At breakfast, we met Chris Moore (chief engineer for the 6880) and his wife, who were on holiday touring the area. They said their schedule wouldn't allow them to make it to Promontory for the event, though they were excited about it. I kinda wish we could've stopped there too, but we didn't have time either. We did talk about the Durango-Silverton a little, since my great grandfather was a conductor on it, and my family and I were planning to head down and ride it a few weeks later to spread my grandfather's ashes.

@Gąska said in TIL (about the Dark Arts of HTML):
TIL the biblical God used to have problems defeating iron chariots.
That's not accurate. It's a misinterpretation of the passage and depends on a possibly unfortunate phrasing in the KJV.
For reference, here's Judges 1:19:KJV: "And the LORD was with Judah; and he drave out the inhabitants of the mountain; but could not drive out the inhabitants of the valley, because they had chariots of iron."
ESV: "And the LORD was with Judah, and he took possession of the hill country, but he could not drive out the inhabitants of the plain because they had chariots of iron."According to this Christianity StackExchange answer, the third clause is subordinate to the second, and the verbs for "drive out" and "took possession" are the same Hebrew word (meaning "dispossess"). Taking those two points together, the actor must be the same in both, and from the parallel constructions in the context (a listing of which tribes or individuals conquered which areas or peoples), that actor would be Judah.
The list of successes and failures tallies with the conditional promises God gave in various passages as listed in this answer: if the people would obey God's commands, He would drive out the inhabitants before them, and conversely, if they disobeyed, He would not help them drive out the inhabitants. It's clear that God had the ability, because not very much later on, the Israelites were able, with God's help, to defeat nations that had iron chariots.

What makes you think I'm upset? If I were easily upset about something like that I wouldn't be a teacher.
It's just sad that you're doubling down on your willful ignorance - nothing new with you, however.
And of course it does lead to confusion - radio waves are defined as a part of the EM spectrum. Which means that "high frequency radio waves" are actually a thing - they'd be around the 100 GHz range. That's still far below the VIS-part of the spectrum.

The high frequency (HF) portion of the radio spectrum corresponds to what is commonly called "short wave" — wavelengths from 100 m to 10 m, or 3 MHz to 30 MHz. Due to the way radio waves are reflected by the ionosphere, nearly all (non-satellite) long-distance radio communication uses frequencies in this region (mostly toward the middle of it; frequencies below about 7–8 MHz tend to be mostly useful for local communication, and frequencies above about 20 MHz are unreliable; they're really good when the ionospheric conditions are right, but the conditions aren't always right).

somemany people on this forum get very riled up about things like this.

Today's episode brought to you by the word "meiosis"!
(Fucking oneboxes, why can't you be more like printers?)
In rhetoric, meiosis is a euphemistic figure of speech that intentionally understates something or implies that it is lesser in significance or size than it really is. Meiosis is the opposite of auxesis, and is often compared to litotes.[1][2][3] The term is derived from the Greek μειόω (“to make smaller”, "to diminish").

@Zecc said in TIL (about the Dark Arts of HTML):
General relativity suggests that really big objects, like planets and stars, actually warp the fabric of spacetime, which results in a gravitational pull capable of slowing down time. Thus, an object closer to Earth's center would feel a stronger pull—a clock set near the core would run slower than one placed at the surface, which means that the material that makes up the core is actually younger than the material that makes up the crust.
wat?
No... the closer to the Earth's center you get, the less gravitational pull you experience. Everything further away from the core than you are all cancels out, so you're effectively feeling the pull of a much smaller planet.
There is a slight increase in gravity at a certain level just due to the mass distribution:
...so maybe that's what they're talking about, but as a general statement it just doesn't hold true.

Yes. But they're still the high frequency part allocated to the area of the spectrum for radio waves. That's the problem with his statement: High in relation to what? If we used his terminology everything from IR to gamma rays would be "high frequency radio waves".

It really is gorgeous. I love that part of the country. I have family that live there.
Our ride on the train was in late June. Actually, on our way back, our train made the local news, unfortunately. Three guys were lazing about next to the track, drunk as a skunk and probably high as a kite, too. One of the guys was too close to the track and got caught and dragged under the cylinder while the train crew slammed on the brakes and stopped the train. It took a few minutes to get him out from under the engine, during which time one of the guys realized that they could be in trouble for being there, grabbed his backpack, and high-tailed it out of there. Somehow, he escaped being part of the article.

Unintentionally, probably, that speech had a far more devastating impact than the conditions he was criticizing. In effect, the chairman of the FCC, speaking for the government, took the position that the networks were responsible for everything they broadcast. The shocking aftermath of that designation of responsibility by Mr. Minow and the FCC gave ABC, CBS, and NBC absolute authority over everything that comes into your living room on network television.
Funny how the opposite would now seem utterly bizarre. Can you imagine networks not being responsible for the content they broadcast?
Also, there is probably some amusing comparison (or informed analysis, if anyone is informed enough...) to make with Facebook and consorts having a hard time deciding whether they are responsible or not of their content.
