I’ve known this for over 20 years and never used it. Thanks catchy mnemonics!
Are you making a crossover cable or installing it for the government? Those are the only places that I know of that A is used regularly. Nearly everywhere else uses B in my experience.
Are you making the assumption I am from North America?
Every place I have worked in Australia and Europe uses green first.
Really? I wasn’t sure which one I “should” use so I looked at a cable that I had laying around (probably came with a cable modem or something?) and was able to see the wire colors through the connector and it was A. So that’s what I’ve been using when making patch cables or wiring my house.
I guess my question is what’s your experience with where B is used? Mostly I’m just curious, it probably doesn’t really matter for me since I only do networking work in my house.
I guess it doesn’t really matter as long as you stick to one for both ends of the cable
It shouldn’t actually matter. It’s strictly by convention that the US (and probably North America; unclear about beyond) almost exclusively uses B. The big risk is that people will assume it’s B, and the other end is B, which can cause issues when they e.g. replace a receptacle and make all of your connections crossover. But even that shouldn’t matter much these days.
There’s also some very limited issues switching from A to B on the same line (A in wall, B in patch cable), but this is very rare. If you saw A, it was probably either a crossover, or you live in a place that uses A.
So I learned all this almost 2 decades ago so the details may be off…
There’s crossover cables, which are a-b and used if you want to connect one computer to another-the tx and rx are flipped from one side to the other, so two “client” devices (like 2 computers) don’t speak and listen on the same line
There’s rollover cables, which are flipped on one side, that were used to connect to the console port of a router
Aside from that, nothing about the configuration really matters except being standard. The reason they’re not just in stripe-color color order is to separate the tx and rx to minimize interference
I’m pretty sure all of this became moot after hundred gigabit Ethernet became a common thing anyways - they multiplex electrical signals across each of the wires, so they have to negotiate the method or fall back to a simpler protocol from the start. I’m not sure how robust it is to randomly shuffling the order on each side individually (I wouldn’t try it on hardware I wasn’t willing to risk)
So really, all that matters is that it matches. And since we’ve been doing it a certain way for so long, doing it differently is a bad idea. A vs b makes no difference, but you could make green the split pair and it’d be identical. You could use the same arbitrary order on each side and you’d probably not notice much difference, although you might get a lot more errors from minute interference
And FWIW, I think b is the more common standard across the world… But any advantage or disadvantage probably died back when we stopped using those trunk lines with dozens of pairs split out on a punch down block that goes to a bunch of different homes
I managed to memorize it for a test in networking class. The teacher was surprised someone actually managed to get it right.

This is basically what I say whenever someone asks me for a fun fact too roflmao
Today I Learned!
And that’s now my fun fact too lol
The little piece of plastic at the end of a shoe lace is called an aglet.
I learned that from Phineas and Ferb.
IT DOESN’T MATTER!!
In what way?
Thank you Terraria for this useless piece of info
Pretty sure it was the movie Repossessed with Leslie Nielsen that taught me this one.
Their true purpose is sinister
I was gonna correct you and say aiglet, but turns out it’s both correct
Seth McFarlane slept in one morning and missed his plane home. Little did he know that this exact plane hit the World Trade Center.
Orcas are a natural predator of the moose
Orcas are a natural predator of everything that his the ocean. Fun fact, orcas have been known to toy with seals by catapulting them with their tails. I believe I remember seeing at least one baby seal got seventy feet in the air before returning to the sea (and its inevitable death).
I hate to break it to ya, but moose aren’t in the ocean.
All cases known to have happened are in Alaska, where moose were swimming across straits and between islands. Orcas are opportunistic hunters and nearly anything swimming in water deep enough for them to swim in has a chance of being eaten. Most of them keep their distance from humans but if you were swimming in their territory away from civilization and boat traffic you might be stalked and hunted.
oh that’s interesting! Thanks I didn’t know that!

2 facts about the CMOS battery on a motherboard: CMOS stands for “complimentary metal oxide semiconductor”. Its a 2032 watch battery.
Also, the 2032 numbering indicates its physical size: it’s 20mm x 3.2mm. There are for example 2025’s (like in my car remote) that are 20mm x 2.5mm.
And CMOS refers to what the battery was powering on the motherboard (a small amount of CMOS static RAM) rather than anything about the battery itself. I don’t know if motherboards still use any static RAM, the batteries might only be there to power the clock these days, making the name just a historical convention.
It goes beyond button batteries too. Lots of batteries use the same system. For instance, many flashlights run off of 18650 cells.
-All of the planets in the solar system can fit between the earth and the moon -Stoplights detect your presence with an electromagnetic field using wires and not pressure -There is a receiver above stoplights that EMS vehicles can trigger to change the light red for everyone -We left astronaut poop on the moon -The numbers on a toaster are not always in minutes -Most common mold is not dangerous when ingested or inhaled unless you are allergic -Celeste Tea was founded and made by a cult, maybe still is -Christian Science had laws passed in the majority of states in the 80s that prevented prosecution of child abuse due to religious practices -The statistical value of a human life in the US is 10 million at dollars -Jellyfish reproduce and are birthed as polyps on the ocean floor -The chiral version of the sugar molecule would taste identical to sugar but is indigestible, we have no practical ways to produce it though afaik -Only one president has failed to release his tax documents -There are multiple US presidents who were likely gay
I’ll stop there, and yes these facts do rotate through my head for no real reason, they’re just fun!

How to get all kremkoins in Donkey Kong Country 2, through a cheat:
- Enter the cabin with the map and the life balloon. Leave without touching anything.
- Collect the banana bunch over the pirate crocodile. Go back to the cabin, now pick the life.
- Repeat the above. You’ll see a kremkoin over the map. Pick it and you got 75 kremkoins.
In no moment you can touch the two lone bananas close to the entrance of the cabin.
…it has been decades since I played this game, and I almost never used the cheat above (it’s less fun than finding all bonus stages). Why do I still remember this?
I still remember the cheat for the first game. Down Y Down Down Y when cranky appears in the title to play bonus stages.
I remember this one too! There was also B A↓B↑↓↓Y (bad buddy) to switch when you wanted in 2P, instead of waiting until the arsehole playing with you to switch it.
Plus LRR LRR LR LR for DKC3. Then you’d insert a cheat and… I don’t remember them. Damn.
Male bedbugs have a knife-like penis. To have sex, they stab the females in the thorax with it because the females don’t have genitalia. The semen is then injected directly into the female’s main body cavity for insemination

The Moon is moving away from the Earth by approximately one inch per year. Which also means that millions of years ago it was much bigger in our sky.
I believe it’s closer to 1,5cm per year.
And if you reverse extrapolate that some 65 million years, you’ll see that the real reason why the dinosaurs ied out was because they all got hit in the head with moon!
If this is true, then 97.5 million cm = ~600 miles. Or, 0.25% of the distance to the moon…a small difference.
It’s not funny anymore if you prove me wrong by math :-)
To add to this, the sun will expand into a red giant in approximately 5 billion years, which is likely to consume both Earth and the Moon. This will happen before the Moon is able to leave Earth’s orbit, so it’ll shrink in the sky but odds are it won’t leave the Earth’s orbit before both are destroyed by the expanding sun in the future.
On top of that, the sun is slowly getting hotter as it gets older, so in approximately 1 billion years, the sun will have gotten hot enough to render most, if not all of the Earth uninhabitable for life as we know it.
Space is fascinating.
aha, I knew it! climate change is a hoax! the sun is just getting hotter, it’s all natural! /s
So, possibly stupid question:
Will the sun’s gravity change as it expands, pulling things out of current orbits, or will it just change in size & not in mass?
Great question!
No, the Sun’s diameter will expand greatly but it’s mass will remain mostly the same, if anything it’ll be ejecting significant amounts of stellar matter when it turns into a red giant and will be losing mass.
Mass is what dictates the gravity of a given object. If you replaced the sun with a black hole of the exact same mass, everything in the solar system would retain its exact same orbit outside of those few unfortunate objects that were very close to the sun (much closer than Mercury) when it got swapped out for a black hole of the same mass.
So even though the Sun will eventually swell up into a red giant and eat most, if not all of the inner planets, it’s gravity will remain the same despite its massively increased diameter, and its gravity will get weaker as the red giant ejects stellar matter over its relatively quick life. Eventually it’ll eject its outer layers, creating a new nebula thanks to the star ejecting all of its outer layers and leaving behind the dead core of a star called a white dwarf. These dead stars are often similar in size to the Earth but typically have a mass close to that of our sun.
