hello
` and the browser shows it in whatever default font, size, whatever. If you want that specific paragraph to be red, you give it a label: `hello
`. That's it. You made up the name \"warning\" out of nothing. It doesn't mean anything until you define it in your CSS.\n\nThen in the CSS file you write a rule that says \"hey, anything labeled warning, make it red\":\n\n.warning { color: red; }\n\nNow every element with class=\"warning\" gets red text. One paragraph, fifty paragraphs, doesn't matter. Change the rule once and they all change.\n\nThe thing that trips people up is the dot. In CSS you use a dot before class names, but in the HTML you don't. So class=\"warning\" in the HTML matches .warning in the CSS. Everyone forgets the dot at first. I did, for like a week.\n\nThe other thing that confuses people is why use a class instead of just targeting the tag itself, like styling all `p` tags. You do that when you want every paragraph to look the same. Classes exist for when you only want some of them. Red text on every paragraph would be insane, red text only on warnings makes sense.\n\nYou can also put multiple classes on one element, separated by spaces, like class=\"warning big\". It gets both rules.\n\nHave you actually tried writing a tiny HTML file and playing with this? Ten minutes of doing it beats an hour of reading about it honestly, this is one of those things that sounds abstract until your own text turns red.", "words": 298, "prompt": "floor", "seed": "eli5c-2610|z-ai/glm-5.3", "target_words": 302, "draws": 7, "post": {"curly": false, "double_space": false, "ellipsis": false, "em_dash": false, "en_dash": false, "lowercase_para": false}} {"doc_id": "eli5c-2614-h", "question_id": "eli5c-2614", "q_id": "2flkgl", "split": "dev", "label": "human", "model": "human", "words": 314, "score": 16, "url": "http://www.reddit.com/r/explainlikeimfive/comments/2flkgl/eli5_what_is_the_point_of_having_the_marine_corps/"} {"doc_id": "eli5c-2614-a", "question_id": "eli5c-2614", "q_id": "2flkgl", "split": "dev", "label": "ai", "model": "qwen/qwen3.8-max", "text": "Think about it this way. You're the President and something breaks out somewhere overseas. You need boots on the ground within days, maybe even hours. You don't have a base there. You don't have time to build one. What you do have is a Navy fleet sitting off the coast. The Marines exist so you can pull a fighting force off those ships and put them on a beach or into a country without needing permission from anyone or needing infrastructure already in place. They carry their own logistics, their own air support, their own artillery, all packed into a self-contained package that rides on Navy vessels.\n\nThe Army is a different animal. It's built for sustained, large-scale ground combat. We're talking hundreds of thousands of troops, massive supply chains, heavy armor divisions, the whole thing. The Army needs time to deploy and it needs ports and roads and airfields. It's the sledgehammer you bring once you've decided this is going to be a long fight.\n\nSo why not just make the Marines part of the Army? Because the Marines are organized around *being ready to go right now* from the sea. Their training, their equipment choices, their unit structure, all of it is optimized for that rapid deployment mission. The Army optimizes for something else entirely. Merging them would mean one of those missions gets shortchanged.\n\nAlso historically the Marines started as shipboard infantry, guys who fought from the decks of warships and handled amphibious assaults. That identity stuck. They developed their own culture and doctrine over centuries.\n\nHave you ever noticed how the Marines are way smaller than the Army? That's intentional. They're not meant to hold territory for years. They're meant to kick the door open.\n\nEdit: I said the Marines carry their own air support, which is true but I should clarify they don't have their own jets in the same way the Air Force does.

That feels unfair when the CEO's paycheck depends on the labor of thousands of workers, but those workers often have little say in how the money is divided.\n\nThe usual argument is that CEOs are paid more because they make bigger decisions and carry more responsibility. That explains some difference. It does not automatically explain why one person should make 200 or 300 times as much as an employee, especially when a company's success also depends on engineers, drivers, cleaners, salespeople, factory workers, and everyone else.\n\nCEO pay is often set by a board made up of other wealthy executives and business people. They may approve huge salaries, bonuses, and stock grants using comparisons with other companies. Since every company wants to say its CEO is \"above average,\" the numbers keep rising. The CEO may also be rewarded for results caused by the whole workforce, or by the general economy, rather than by their own decisions alone.\n\nMeanwhile, low-level workers usually have less bargaining power. An individual employee can be replaced, and refusing low pay may mean losing their income. A CEO can threaten to leave, negotiate with the board, or receive valuable shares and bonuses. That means the pay difference is not just measuring skill or effort. It is also measuring power.\n\nPeople are especially angry when executives receive enormous bonuses after layoffs, wage cuts, pollution, fraud, or a company being rescued with public money. It makes the system look like losses belong to workers and taxpayers, while gains belong to executives and shareholders.\n\nThe complaint generally is not \"everyone must earn the same.\" It is that the gap has become so large that it reflects a system giving the people at the top far more control over the money than the people whose work creates it.", "words": 349, "prompt": "floor", "seed": "eli5c-2619|openai/gpt-5.6-luna-pro", "target_words": 344, "draws": 4, "post": {"curly": false, "double_space": true, "ellipsis": false, "em_dash": false, "en_dash": false, "lowercase_para": false}} {"doc_id": "eli5c-2632-h", "question_id": "eli5c-2632", "q_id": "6hfhrw", "split": "dev", "label": "human", "model": "human", "words": 465, "score": 10, "url": "https://www.reddit.com/r/explainlikeimfive/comments/6hfhrw/eli5_with_television_and_more_recently_the/"} {"doc_id": "eli5c-2632-a", "question_id": "eli5c-2632", "q_id": "6hfhrw", "split": "dev", "label": "ai", "model": "nvidia/nemotron-3.5-lightning", "text": "The other night I was flipping through the channels and landed on a documentary about a small fishing village on the coast. The voice-over was smooth, clipped, standard whatever you call it. But the men on screen? They still said \"innit\" and \"me old mucker\" and phrases that sounded like they'd been pulled straight from a London street market in the nineteen-seventies. It made me think about how we talk now. The theory you've got in your head, that a common tongue would eventually flatten into one approved version, does hold some water, especially when you look at the last hundred years or so.\n\nThink about the radio age. Before that, if you lived in a valley or on an island, your version of the language was what you heard. Your grandparents, your next-door neighbor, the bloke at the pub. You might understand someone from the next town over, but you'd have to slow down, maybe ask them to repeat yourself. Dialects survived because they were physically locked in place. Then radio came along, and later television, and suddenly you had a voice broadcasting into every home at the same time. It wasn't just the newsreader or the soap opera star. It was the advertisements, the talk shows, the sitcoms. All speaking the same received pronunciation, the same \"proper\" way of saying things. For a lot of people, that became the benchmark. If you wanted to be understood by the wider world, or if you wanted to get a job in the city, you started shaping your own speech to match what you were hearing out of that glowing box.\n\nThe internet accelerated that process tenfold. Back in the day, if you wanted to talk to someone who spoke differently, you had to actually travel or write a letter. Now, a kid in Manchester is chatting online with someone from Glasgow, or Auckland, or Melbourne. They're all reading the same threads, watching the same memes, using the same slang that originates on one platform and gets picked up everywhere else in a matter of hours. The pressure to conform is constant. You don't want to be the person everyone has to decode. So people adjust. They lose the distinct vowel sounds, they soften the regional phrases, they start using the same filler words everyone else is using. It's not always a conscious choice. It's just easier to type the way the majority types.\n\nbut here's the thing that often gets overlooked in this narrative of homogenization. Dialects aren't just random collections of words you can swap out like outfits. They're tied to identity. They're tied to a sense of belonging. When someone starts losing their regional inflections, they might feel like they're losing a part of themselves, even if they're gaining \"clarity\" or \"status.\" You see communities pushing back against it. You see schools teaching local history and local speech patterns, not just the standard version. You see regional broadcasters making a comeback, deliberately using their own accents because there's an audience for it, because people are tired of hearing the same five voices on every channel.\n\nSo yes, the dominance of a standard dialect is real. The machinery of media and the internet applies a lot of pressure to smooth out the rough edges. But it's not a one-way street where everyone eventually stops being regional. Some people do fade into the middle, especially the younger ones who are heavy users of social media. But a lot of others are holding onto their specific way of talking, partly out of habit, partly out of pride, and partly because the internet also gives them a platform to be heard without having to modify themselves to fit the mainstream. The dialect might get quieter in the broader public square, but it doesn't necessarily disappear. It just moves, often into tighter, more specific circles where being from a certain place still means something.", "words": 651, "prompt": "floor", "seed": "eli5c-2632|nvidia/nemotron-3.5-lightning", "target_words": 465, "draws": 5, "post": {"curly": false, "double_space": false, "ellipsis": false, "em_dash": false, "en_dash": false, "lowercase_para": true}} {"doc_id": "eli5c-2646-h", "question_id": "eli5c-2646", "q_id": "5yebuh", "split": "dev", "label": "human", "model": "human", "words": 293, "score": 84, "url": "https://www.reddit.com/r/explainlikeimfive/comments/5yebuh/eli5_why_do_restaurants_serve_small_items_on/"} {"doc_id": "eli5c-2646-a", "question_id": "eli5c-2646", "q_id": "5yebuh", "split": "dev", "label": "ai", "model": "nvidia/nemotron-3.5-lightning", "text": "They do it so the food looks lonely.

He wants higher taxes on high earners and companies, more public ownership of things like railways, stronger trade-union rights, more spending on public services, and less reliance on military intervention abroad. So he has made ideas that were treated as fringe inside Westminster sound normal to a lot of voters again.\n\nFor Labour, that brings in people who had stopped voting for it, especially younger people and activists. His 2017 election campaign showed that a left-wing manifesto could attract a large vote, even though Labour did not win. It also made Labour membership much bigger and more active.\n\nBut his leadership has made Labour a very divided party. The MPs are more moderate on average than the members, and many of them do not trust Corbyn's judgement or his small group of advisers. Corbyn's supporters see this as MPs trying to block a democratic change. His critics see a leader who is poor at making decisions, unclear on national security, and too tolerant of factions that have behaved badly.\n\nBrexit makes that division much worse. Labour has voters who strongly want to leave and voters who strongly want to remain. Corbyn personally dislikes the EU's economic rules, but he has tried to keep both groups onside instead of making a clear choice. Can a party represent both sides when Brexit has become people's main political identity? That is the problem Labour keeps running into.\n\nFor British politics generally, Corbyn has shifted the argument toward inequality, public ownership, housing, and who gets power at work. Even parties that dislike him have had to respond to those issues. He has also made politics more openly hostile and factional, with arguments about socialism, antisemitism, Brexit, and whether Labour should be a broad election-winning party or a movement for changing the country.\n\nMy read is that Corbyn is less a normal Labour leader than a sign of Labour's unresolved fight over what it exists to do. *Winning elections and changing society are related, but they are not the same job.* His supporters think winning requires offering a real alternative; his opponents think offering that alternative in Corbyn's form makes winning much harder.\n\nEdit: I said Labour did not win in 2017; it won more seats and votes than expected, but the Conservatives remained the largest party and formed the government.", "words": 400, "prompt": "floor", "seed": "eli5c-2647|openai/gpt-5.6-luna-pro", "target_words": 349, "draws": 7, "post": {"curly": false, "double_space": false, "ellipsis": false, "em_dash": false, "en_dash": false, "lowercase_para": false}} {"doc_id": "eli5c-2659-h", "question_id": "eli5c-2659", "q_id": "fmzyo5", "split": "dev", "label": "human", "model": "human", "words": 296, "score": 20, "url": "https://www.reddit.com/r/explainlikeimfive/comments/fmzyo5/eli5_how_do_the_graphics_card_ram_and_processor/"} {"doc_id": "eli5c-2659-a", "question_id": "eli5c-2659", "q_id": "fmzyo5", "split": "dev", "label": "ai", "model": "z-ai/glm-5.3", "text": "TL;DR: They're a team, and performance is capped by whichever member is slowest at the job the game or program is asking for, kind of like a relay where one runner can drag everyone down.\n\nThe CPU is the decision maker.

The GPU then takes those instructions and does the brute-force work of actually drawing the frame, millions of pixel calculations per second. RAM is the shared workbench both of them use to keep data close at hand instead of constantly fetching it from your much slower SSD or hard drive.\n\nSo in a game, the CPU prepares a frame, hands it to the GPU, the GPU draws it, and RAM holds the textures, models, and game state everyone needs quick access to. This happens 60 or 100-plus times a second.\n\nThe annoying part is that \"which part matters\" depends entirely on what you're doing. A demanding shooter at 1440p is mostly GPU work, so a mid-range CPU paired with a strong card is fine.

Scrubs are designed to be washed at high temperatures with industrial detergents.

You have to decide what your base reality is before you can build anything on top of it.\n\nTerminological relations are how you define the connections between the words and concepts in that system.

He thinks our knowledge is more like a giant web where every part touches every other part, so when an experiment fails, you have to decide whether to change your facts, your definitions, or your logic.

That kind of setup means they spend a lot of time figuring out what other animals are doing so when a boat or a swimmer shows up they come over to check it out instead of bolting.

They control the water they can dive deep or swim off at thirty knots whenever they want so there is no need to act scared or aggressive. I remember reading they recognize themselves in mirrors which means they know they are separate from the rest of the world and can tell a human is not another orca or a rival. That awareness lets them stay relaxed around us because they already know we cannot really hurt them in their own backyard.\n\nSometimes they follow boats for hours or come up under divers just looking then they lose interest and peel off. It is not friendship exactly more like they have decided we are harmless background noise. In captivity it is different they get bored and stressed but out there they have space and their own hunts and the pod to keep them busy. I have never heard of a wild one actually biting someone on purpose they might bump a boat now and then but that is rare and usually they just ignore us completely.

When the NSA collects everyone's phone metadata and internet traffic, they're not targeting criminals, they're targeting everyone, and \"we'll only look at the bad guys later\" is not a real safeguard because the data is already sitting there. A warrant is supposed to be a check you pass before you get the information, not after. Once the haystack exists, any future government, any future director, any rogue contractor with access can dig through it, and history says they will, because every single FISA-court reform happened only after abuses were already found.\n\nThe second thing is that it doesn't actually work. The NSA's own documents from the Snowden dump showed bulk collection produced essentially no unique terrorism leads, the famous \"54 attacks\" figure collapsed under questioning and ended up being something like one or two cases where bulk data was maybe marginally useful. So we're trading away privacy of hundreds of millions of people for a program that mostly catches idiots who were already visible to the FBI. That's a bad trade even if you don't care about civil liberties at all, and I find the fact that this part gets ignored kind of infuriating.\n\nThird, mass collection makes chilling behavior normal. People search different things, talk to different sources, join different groups, when they know everything is logged. Journalists talking to whistleblowers is the obvious casualty, and Snowden himself is literally an example of why that pipeline matters.\n\nThere's also the trust angle: US companies had to hand data over secretly, foreign customers noticed, and it cost billions.

A half empty parking lot with half empty registers scares people off more than a full lot with a line snaking out the door. So they run the lights and the doors open even when nobody is buying anything just so the place feels like it is operating at capacity.\n\nThe registers themselves are old technology. The scanners and the credit card readers were designed ten years ago and they just keep using the same models because retooling the whole floor costs more than just letting the current ones break. When a scanner jams or a card reader glitches the employee has to stop what they are doing and fix it which slows down the line they are supposed to be running.\n\nThey also do not schedule enough people during the rush.

The installer is a compressed package full of hundreds or thousands of files that have been squashed together to save download time. If you could just open that package, you would not see a playable game. You would see a mess of data files, libraries, and folders with names that mean nothing to a human. Opening it directly is like opening a flat-pack box and expecting the furniture to already be standing up. The install step unfolds and sorts all that into a proper folder structure the game expects.\n\nThe bigger reason is that a game is not a single self-contained program. It depends on a bunch of other software that already has to be on your computer: graphics drivers, sound systems, DirectX, Visual C++ runtimes, and so on. The installer checks whether those pieces are present and, if not, puts them in the right place or tells you to update. If you skipped installing and just double-clicked the game's raw executable, it would often throw a missing DLL error, crash on startup, or show a black screen because a runtime it needs is not registered. That is not the game being broken. That is the game trying to use a shared component that was never set up.\n\nThere is also the question of where the operating system expects things to live. Installed programs get a dedicated folder, usually under Program Files, with proper read and write permissions. That matters because a game needs to write save files, settings, cache data, and logs somewhere. Your browser's download folder is not set up for that. If you ran a game straight out of a zip file on the desktop, Windows or macOS might block it from saving anything because it does not have the right permissions in that location. An installer creates the folder and sets the permissions so the game can actually store your progress.\n\nAnother part is registration. When you install a game, the installer writes entries into the system registry or equivalent config files. Those entries tell the system the program exists, where its uninstaller is, what file types it can open, and where its shortcuts go. Without that step, the game is just a loose pile of files. Some people think installing is just copying files. That is the dumbest part! Copying is one small piece, but the real work is decompressing, checking dependencies, setting permissions, registering the program with the OS, and creating an uninstall path. If you just copied the whole game folder from a friend's machine, you would often end up with broken shortcuts and missing registry entries, even though every file appears to be there.\n\nSmall self-contained utilities can sometimes run without an install because they do not need shared runtimes or registry hooks. But a full videogame with gigabytes of art, audio, and system-level calls is not in that category. The install process is what turns a compressed download into something the computer actually knows how to launch and keep running. Opening the raw package would not do that. It would just leave you staring at a folder full of parts with no way to start the actual game.", "words": 543, "prompt": "floor", "seed": "eli5c-2690|deepseek/deepseek-v4-pro", "target_words": 567, "draws": 7, "post": {"curly": false, "double_space": false, "ellipsis": false, "em_dash": false, "en_dash": false, "lowercase_para": false}} {"doc_id": "eli5c-2701-h", "question_id": "eli5c-2701", "q_id": "ai9mie", "split": "dev", "label": "human", "model": "human", "words": 271, "score": 23, "url": "https://www.reddit.com/r/explainlikeimfive/comments/ai9mie/eli5_how_did_the_modern_guitar_come_to_be_why/"} {"doc_id": "eli5c-2701-a", "question_id": "eli5c-2701", "q_id": "ai9mie", "split": "dev", "label": "ai", "model": "z-ai/glm-5.3", "text": "The guitar basically descends from a long family of fretted string instruments going back to things like the lute and the vihuela in Spain. By the 1800s you had something recognizably guitar-shaped, and a guy named Antonio de Torres in the mid-1800s is usually credited with setting the template for the modern acoustic: bigger body, fan bracing under the top, six single strings instead of the older doubled-string setups. Steel strings and eventually pickups came later, and the electric guitar in the 1930s and 40s just kept the same layout because players already knew it.\n\nAs for one string per note, think about what that would actually require. A piano covers its range with 88 separate strings because each one only has to do one job. A guitar has six strings but the fretboard lets you shorten any string with your finger, so each string can produce twenty-plus notes depending on where you press. You get a huge range out of a compact, playable instrument. If you wanted, say, 40 chromatic notes and a string for each, you'd need a neck the width of a coffee table, and how would you even fret that? You'd basically be inventing the piano again, just laid flat.\n\nThe tuning itself, EADGBE, is also a compromise that makes chords reachable. The strings are spaced so that common chord shapes fall under your fingers in nice patterns. A one-note-per-string design would kill that entirely. Some instruments do go the \"more strings\" route, like harp guitars or 12-strings, but there's a practical limit to what a human hand can grab.

Operators also picked a fresh wheel order and start position every morning and swapped extra letters on a plugboard. That combination produced more possible daily keys than anyone could try by hand. Polish mathematicians had already rebuilt the machine and written out the wiring, so Turing started from there instead of from zero. He realised that certain common phrases turned up again and again in German traffic, weather reports especially, and those phrases could be used as cribs. A crib is just a guessed stretch of plaintext lined up against the ciphertext. Because Enigma never maps a letter to itself, you can slide the crib along until no letter sits on top of itself. Once you have a possible alignment you look at the chains of substitutions the machine would have to make. Some of those chains close into loops. A wrong rotor setting will almost always produce a contradiction inside those loops, because the plugboard swaps have to stay consistent all the way around. The Bombe was built to hunt for the rare settings that do not contradict themselves. It was a rack of replica Enigma drums spinning at high speed, electrically linked so that a current could race around the same loops the mathematicians had drawn on paper. When the current found a closed path that did not short out, the machine stopped and a set of candidate rotor positions lit up. Operators then tested those few candidates on a real Enigma replica and read the rest of the message. The Bombe did not search every possible key. It only tested the combinations that could satisfy the loop condition, which cut the work down from years to hours. Dozens of the machines ran in parallel, each loaded with a different crib or a different wheel order. Turing's contribution was the way of turning those loops into an electrical circuit that could be checked automatically. The rest was just keeping the drums oiled and feeding them fresh cribs as the Germans changed their habits. Once the daily key dropped out, every message sent that day could be read in the clear.

A lot of voters felt the recovery under Obama was just moving way too slow, unemployment stayed high for years, and the stimulus spending didn't fix things fast enough. Romney spent his entire career in the private sector turning failing businesses around at Bain Capital, and he fixed the finances of the 2002 Salt Lake City Olympics when they were in trouble. The core idea was that the country needed a turnaround manager with actual executive business experience running things instead of a community organizer and law professor.\n\nThen there was the national debt and government spending. Conservatives were genuinely freaked out by the debt crossing 16 trillion dollars and the massive yearly deficits during Obama's first term. Romney and his running mate Paul Ryan ran on cutting spending, simplifying the tax code by lowering rates while closing loopholes, and paring back regulations that they argued were keeping companies from hiring. If you run a small business, do you want to deal with thousands of pages of new federal rules every year? That was their pitch to working people and entrepreneurs.\n\nA lot of the energy was also about the Affordable Care Act. Republicans hated the individual mandate, which forced people to buy health insurance or pay a fine, seeing it as federal overreach. Even though Romney had set up a somewhat similar system as governor of Massachusetts, his 2012 platform promised to repeal Obamacare and replace it with state-level policies and market reforms that didn't involve federal mandates.\n\nOn foreign policy, Romney argued that Obama was projecting weakness abroad and apologizing for American power. He famously called Russia our *number one geopolitical foe* during the debates, which drew a lot of mockery from Democrats at the time, but conservative voters agreed with his view that the world was getting more dangerous. They wanted higher defense spending and a more assertive stance in the Middle East, especially regarding Iran's nuclear program and the aftermath of the Arab Spring.\n\nBasically, if you voted for Romney, you believed the private sector creates wealth, not the government, and that four years of Obama had led to stagnant growth, huge debt, and too much regulation.

The extreme demands have been softened or are only enforced on the few who go into the priesthood. It's not one person's personality cult anymore; it's a tradition that millions share without feeling like they're joining something weird. Even within big religions you'll hear people calling the more demanding, isolated sub-groups \"cults\", like some Mormon offshoots or ultra-orthodox communities that cut people off. That shows the word is more about behavior than belief.\n\nWhy one gets frowned on more? Because cults are new and scary and we can see the manipulation happening in real-time. A religion did the same stuff a thousand years ago but now it's just the water we swim in. If your neighbor joins a church you grew up with, you shrug. If they join a group where they have to live in a compound and hand over their house to a guy who says he's the reincarnation of Moses, you get nervous. The harm is more obvious and the group hasn't had time to sanitize its image or build a lobbying arm. It's not that different at the core, it's just that society has already certified one as safe.

Think hedge funds, money-market funds, finance companies, mortgage lenders, private credit funds, and sometimes investment banks' less-bank-like operations. They may raise money from investors, borrow short-term, then lend or invest for longer periods.\n\nFor example, a finance company might borrow $100 million for a few months and use it to make five-year car loans. That can work fine while everyone trusts the company and keeps renewing the short-term loans. If confidence vanishes, the lenders demand their money back, but the car loans cannot be collected immediately. The company has to sell assets quickly, often at a loss, and can collapse.\n\nThat is basically a bank run, just without people standing outside a branch.

Windows sits on top of a whole stack of stuff, drivers, services, background processes, that antivirus thing checking your save files every five minutes. All of that sits in RAM and cycles CPU time, even when you're just trying to launch a game. SteamOS strips all that away. It's a Linux-based system built specifically to run one thing: games. There's no desktop clutter, no explorer.exe chewing up cycles, no mandatory updates that pop up while you're in the middle of a match.\n\nBecause the OS isn't doing a bunch of generic PC stuff, the graphics drivers can talk directly to the hardware. On Windows, the graphics layer has to translate requests through several hoops before it gets to the GPU. On SteamOS, the translation layer is thinner. That means more of the GPU's actual power ends up rendering pixels instead of managing overhead. People notice this most with older games or titles that aren't heavily optimized for Windows' sprawling ecosystem. You can often get higher frame rates at the same settings, or the same frame rates with lower settings, which can make a big difference on a deck or a low-powered PC.\n\nThen there's the controller side of things. SteamOS was built with the Steam Deck in mind, so the way it handles input is seamless. You don't have to hunt for third-party wrappers or fiddle with xinput settings to get a gamepad to behave. It just works. And because it's Linux under the hood, a lot of indie titles that never got a Windows port run fine, often with better performance than you'd expect.\n\nThe catch is that you lose some flexibility. Windows lets you install anything, tweak any setting, run any background app. SteamOS asks you to commit to the Steam ecosystem. If you're the type who likes to mod Skyrim with thirty different patches and run Discord, Spotify, and a browser all at once while playing, Windows is still your home.

Hodges* in 2015 is the thing that flipped the switch. The Court ruled that the Fourteenth Amendment's guarantees of due process and equal protection mean states can't deny marriage licenses to same-sex couples, and they have to recognize such marriages performed elsewhere. That was a 5-4 ruling, and it instantly made every state-level ban on gay marriage unconstitutional.\n\nBefore that, the country was a patchwork. Some states had legalized it through legislation or state court rulings, others had constitutional amendments banning it. In the couple of years leading up to *Obergefell*, a wave of federal appeals court decisions struck down bans in a bunch of states, that's likely the 18 you're talking about. Those rulings were binding in their circuits, but they only covered the states in that circuit. The Supreme Court then took the case and settled it nationwide.\n\nSo why does it seem like Texas or other holdout states are still imposing bans? They aren't, not really. Texas still has a constitutional amendment and a statute on the books that define marriage as between one man and one woman. That language is still there because the state legislature hasn't bothered to repeal it, and the political will to do so is basically zero. But thanks to *Obergefell*, those laws are a **dead letter**. No county clerk can legally refuse to issue a marriage license to a same-sex couple. If they tried, they'd get sued in federal court and lose immediately, with the state picking up the legal bill! The same goes for any other state with an old ban still sitting in its code. The Supreme Court's ruling is the supreme law of the land under the Supremacy Clause, so every state official is bound by it, regardless of what their state constitution says.\n\nEver wonder why they don't just clean up the statutes? It's mostly a political statement. Removing the ban would require admitting it's wrong, and that's a fight some lawmakers don't want. But the practical effect is zero, gay couples can marry in every county in Texas, and have been able to since June 26, 2015. The 18 states you mentioned were just the last batch of holdouts that had their bans knocked down by federal appeals courts before the Supreme Court settled it for everyone.

It isn't always a conspiracy, though it often feels like one. There are a few concrete reasons why a phone or laptop that felt snappy three years ago feels sluggish today.\n\nFirst, software changes faster than hardware improves. An app that was lightweight when your device was new gets updated with more features, bigger images, more background processes, and heavier code. That app still runs on your old hardware, but now it demands more of it. The operating system itself also evolves. New versions of Android or iOS or Windows add features that your older processor and memory weren't built to handle efficiently. You aren't necessarily imagining things, your hardware is being asked to do more work than it was originally built for.\n\nSecond, batteries degrade. This is one of the most common and frustrating factors. A lithium-ion battery is meant to hold a certain amount of charge, but every charge cycle wears it down slightly. After a couple of years, the battery can't deliver the peak power the processor wants during heavy tasks. The phone or laptop may throttle the CPU to prevent a sudden shutdown, which makes everything feel slower. You can replace the battery, but most people don't, and manufacturers make it intentionally difficult to do so on many models.\n\nThird, storage gets fuller. As you take photos, download apps, save files, and update systems, the drive fills up. When a hard drive or SSD is nearly full, the system has less room to operate efficiently. It struggles to find contiguous space for new data, and the file system has to work harder to keep track of everything. That slowdown is real and cumulative.\n\nFourth, manufacturers stop supporting older devices with security patches and optimization updates. Once a model is two or three years old, the company may shift its engineering resources to newer releases. The old device still works, but it no longer gets the performance tweaks and security fixes that keep things running smoothly. It becomes a version of itself that is increasingly out of sync with the current ecosystem.\n\nNone of this is inevitable in a perfect world, but in the market we have, the incentives align toward encouraging upgrades. Better technology does often mean longer usable lifetimes, but it also means the baseline of what \"works well\" gets raised, and your old device gets left behind at the old baseline.", "words": 428, "prompt": "floor", "seed": "eli5c-2806|nvidia/nemotron-3.5-lightning", "target_words": 507, "draws": 7, "post": {"curly": false, "double_space": false, "ellipsis": false, "em_dash": false, "en_dash": false, "lowercase_para": false}} {"doc_id": "eli5c-2812-h", "question_id": "eli5c-2812", "q_id": "3nk9km", "split": "dev", "label": "human", "model": "human", "words": 328, "score": 13, "url": "https://www.reddit.com/r/explainlikeimfive/comments/3nk9km/eli5_why_does_it_seem_like_were_all_far_better/"} {"doc_id": "eli5c-2812-a", "question_id": "eli5c-2812", "q_id": "3nk9km", "split": "dev", "label": "ai", "model": "deepseek/deepseek-v4-pro", "text": "TL;DR: You notice others' mistakes because they stand out, but you excuse your own as one-off flukes that don't reflect your actual skill.\n\nWhen you're driving, you're inside your own head, aware of every reason you swerved slightly, the sun was in your eyes, the GPS just yelled something, your coffee spilled. So that near-miss feels like a justified reaction to a rare situation, not a sign you're a bad driver. Meanwhile, the guy who just veered into your lane? You saw no coffee, no sun, just a car cutting you off. Your brain slots him immediately into \"reckless asshole\" because the only data you have is the action itself. This is *the fundamental attribution error*: you attribute your own missteps to external circumstances, but attribute others' identical missteps to their personality or incompetence.\n\nAlso, you remember the scary moments others cause far more vividly than your own mundane slip-ups. You probably rolled through three stop signs this week without thinking, but they didn't result in a crash or a horn, so they vanish from memory.

The premise here is a little off in a way that's understandable but worth correcting. Joplin, Missouri got wiped out in 2011. Moore, Oklahoma gets hit over and over. Tuscaloosa, Nashville, Dallas have all taken direct hits in relatively recent memory. So it's not that tornadoes avoid urban areas. They don't care what's underneath them.\n\nThe reason it feels like they never hit major cities is mostly a math problem. A tornado's damage path is usually a few hundred yards wide, maybe a mile in a really violent case. The total land area of the Midwest is enormous. Chicago's downtown is maybe a couple square miles of dense stuff surrounded by a metro area that's still mostly suburbs and open land. The odds of a tornado's narrow path threading through the specific blocks that would cause a catastrophic urban disaster are low on any given day. Not zero, just low. It's like throwing a dart at a wall and trying to hit a specific postage stamp. You'll hit the wall plenty, but the stamp is small.\n\nI've seen people try to argue there's some urban heat island effect that disrupts tornado formation over cities, and I think that's probably overstated. There might be something to it in terms of very localized wind disruption, but it's not a shield. Cities get hit. They just don't get hit often enough for it to dominate the news cycle the way a rural tornado does, partly because a tornado in a rural area can still kill dozens of people and level entire neighborhoods.\n\nAs for nuclear plants, this one is more straightforward. The Nuclear Regulatory Commission requires plants to be designed to withstand tornado winds up to a certain speed, I believe it's around 200 mph for the critical structures. The containment buildings are thick reinforced concrete. They're basically bunkers. A tornado can rip the roof off a turbine building or knock out external power lines, and that's a problem, but the reactor itself is sitting inside something that was engineered specifically so a tornado can't breach it. The Fukushima disaster was an earthquake and tsunami, not a wind event. The failure modes for nuclear plants are different from what a tornado actually does to structures.\n\nSo it's not that nobody's thought about it. It's that the statistical likelihood of a direct hit on the most vulnerable part of a city is low, and the specific infrastructure you're worried about was built to take the hit anyway.", "words": 418, "prompt": "floor", "seed": "eli5c-2822|qwen/qwen3.8-max", "target_words": 442, "draws": 6, "post": {"curly": false, "double_space": false, "ellipsis": false, "em_dash": false, "en_dash": false, "lowercase_para": false}} {"doc_id": "eli5c-2829-h", "question_id": "eli5c-2829", "q_id": "5c9k9m", "split": "dev", "label": "human", "model": "human", "words": 408, "score": 19, "url": "https://www.reddit.com/r/explainlikeimfive/comments/5c9k9m/eli5_is_it_possible_for_every_country_to_be_a/"} {"doc_id": "eli5c-2829-a", "question_id": "eli5c-2829", "q_id": "5c9k9m", "split": "dev", "label": "ai", "model": "qwen/qwen3.8-max", "text": "The short answer is that there aren't hard physical limits preventing it, but the way economies are structured makes it very difficult in practice.\n\nPeople often assume it's like a pie - if one country gets a bigger slice, another gets less. That's not really how wealth works. Wealth isn't just stuff sitting around waiting to be divided up. It gets created through labor, technology, trade, innovation. The total amount of wealth in the world has grown enormously over the past few centuries, and it could keep growing. So the idea that there simply isn't enough to go around is wrong in a basic sense.\n\nBut here's where it gets complicated. When we say a country is \"developed\" or \"first world,\" we're not just talking about people having enough food and a roof over their heads. We're talking about high GDP per capita, advanced infrastructure, strong institutions, access to global financial systems, high-value industries. A lot of that status depends on position within the global economy, not just on having resources domestically.\n\nIf every country tried to consume resources at the rate the US does, we'd need something like four or five Earths worth of material throughput. So there IS a resource argument, but it's specifically about the consumption patterns of the wealthiest countries, not about whether everyone can have a decent life. A comfortable life doesn't require a suburban house with two cars and a lawn.\n\nThe bigger problem is structural. Developed countries got there through a combination of industrialization, colonial extraction, favorable trade terms, and accumulated capital over generations. They sit at the top of global supply chains, doing the high-value design and finance work while lower-income countries do the extraction and assembly. That hierarchy is self-reinforcing. It's not impossible to move up - South Korea and Singapore managed it - but it doesn't happen by accident and it usually takes decades of deliberate policy.\n\nAlso, a lot of what makes a country \"developed\" is institutional. Rule of law, low corruption, functioning legal systems, education infrastructure. These take time to build and can be undermined by external pressures, debt burdens, political instability.\n\nSo can every country reach that level? There's no physical law saying no. But the current global economic system isn't really set up for everyone to be at the top simultaneously, because being at the top partly means others are below you doing the cheaper labor and resource extraction.\n\nEdit: I said \"four or five Earths\" but that figure is specifically about replicating US-level consumption globally.

Those differences give someone a head start.\n\nA child who notices that two notes are slightly different may learn music faster. Someone with unusually good hand control and visual memory may make drawing look easy. They still have to learn what the notes or shapes mean, but the basic information may come to them more clearly.\n\nThe environment adds to this. A child who grows up around music may pick up rhythms without consciously studying them. Someone who draws a lot because people praise their pictures gets more practice, which makes them improve, which makes them want to practice more. That can look like \"natural talent\" even when it is partly an early advantage plus years of practice nobody noticed.\n\nPeople also start with different interests. If an activity feels rewarding instead of frustrating, I'm more likely to spend time doing it. Practice then builds the brain's connections and makes the skill easier.

Good teaching and focused practice can matter more than raw ability in many cases!\n\nEdit: I said \"genes can affect\" these abilities, not that genes determine them; talent is usually a mix of inherited traits, experience, motivation, and practice.", "words": 288, "prompt": "floor", "seed": "eli5c-2835|openai/gpt-5.6-luna-pro", "target_words": 266, "draws": 7, "post": {"curly": false, "double_space": true, "ellipsis": false, "em_dash": false, "en_dash": false, "lowercase_para": false}} {"doc_id": "eli5c-2842-h", "question_id": "eli5c-2842", "q_id": "66b2kj", "split": "dev", "label": "human", "model": "human", "words": 628, "score": 53, "url": "https://www.reddit.com/r/explainlikeimfive/comments/66b2kj/eli5_why_do_we_find_certain_songs_catchy_over/"} {"doc_id": "eli5c-2842-a", "question_id": "eli5c-2842", "q_id": "66b2kj", "split": "dev", "label": "ai", "model": "openai/gpt-5.6-luna-pro", "text": "When I hear a song, my brain is constantly guessing what sound comes next. Most music gives it enough patterns to make those guesses, but not so many that everything is completely obvious. A catchy song often sits right in that middle area: the melody is easy to follow, the rhythm is clear, and there is one small surprise that makes me want to hear the next part.\n\nA simple melody is easier for my brain to remember than a complicated one. Repeated notes, short phrases, and a strong beat give it something to hang onto. Lyrics help too, especially if they use a phrase that repeats several times. After hearing the chorus, I can often \"play\" part of it in my head without consciously trying.\n\nThe song also gets tied to emotion and attention. If I hear it during a funny video, a stressful day, a party, or some other moment I remember, my brain stores the music along with that situation. Songs are particularly good at triggering memories because they involve timing, sound, words, and emotion all at once. Even hearing a similar beat or phrase later can bring the original song back.\n\nThere is also a reward component. Predicting the next note correctly feels a little satisfying, and music can cause the brain to release chemicals involved in pleasure and motivation. A catchy chorus gives me lots of small, predictable payoffs, with just enough variation to keep me listening. This is why a song can feel enjoyable at first and irritating after the twentieth repetition: the reward fades, but the mental replay can continue.\n\nAn \"earworm\" happens when that replay system keeps running after the song has stopped. I may remember only a short section, usually the most repetitive or emotionally strong one. My brain starts the phrase, reaches the end, and then the structure naturally points back to the beginning. It is less like deciding to listen to the whole song and more like getting a short loop stuck in a program.\n\nThe brain is also more likely to repeat something when I am doing a task that does not use much attention, like walking, washing dishes, or riding in a car. Some of my attention is free, so the remembered music fills the space. If I am deeply occupied with something else, the song often disappears for a while.\n\nwhy do some songs stick more than others? Partly because they have been designed that way. Pop music commonly puts the main hook near the start, repeats the chorus, uses a steady beat, and keeps the vocal melody within a range that is easy to sing. But personal taste matters too. A song that is catchy to me may do nothing for you because your memories, habits, and expectations are different.\n\nHave you ever noticed that the song gets stuck after you hear only one line or even someone mention its title? That is because the brain does not need the entire recording. Once it has enough of the pattern, it can reconstruct the rest from memory. Sometimes hearing the full song, or deliberately replacing it with another complete song, breaks the loop because the brain finally gets an ending.", "words": 534, "prompt": "floor", "seed": "eli5c-2842|openai/gpt-5.6-luna-pro", "target_words": 628, "draws": 6, "post": {"curly": false, "double_space": false, "ellipsis": false, "em_dash": false, "en_dash": false, "lowercase_para": true}} {"doc_id": "eli5c-2847-h", "question_id": "eli5c-2847", "q_id": "6obw88", "split": "dev", "label": "human", "model": "human", "words": 406, "score": 14, "url": "https://www.reddit.com/r/explainlikeimfive/comments/6obw88/eli5_what_would_happen_if_you_walked_into/"} {"doc_id": "eli5c-2847-a", "question_id": "eli5c-2847", "q_id": "6obw88", "split": "dev", "label": "ai", "model": "deepseek/deepseek-v4-pro", "text": "At 200 sieverts, the cause of death is *not a heart attack*.

Sleep is a specific brain state with cycles and patterns and you can be woken from it. General anesthesia is closer to a controlled, reversible coma. Your brain isn't cycling through anything, it's just largely offline.\n\nThe drugs used do different things depending on which ones they pick, but most of the common ones like propofol or the inhaled gases work by cranking up inhibitory signaling in your brain. Your neurons communicate through chemical signals, and some of those signals are excitatory meaning \"fire\" and some are inhibitory meaning \"shut up.\" Anesthetic drugs mostly boost the inhibitory side, particularly through receptors called GABA-A. When those receptors get activated, the neuron becomes much less likely to fire. Flood enough of the brain with that signal and consciousness just... stops. You don't form memories, you don't process pain, you don't have awareness. Some drugs like ketamine go the other direction and block excitatory receptors instead, but the end result is similar.\n\nFor dosage, it's not like taking a pill where you read the bottle and take two. The anesthesiologist is making real-time decisions the entire time. They start with a baseline based on your weight, age, and medical history. A healthy 25 year old and a 70 year old with heart problems are going to get very different amounts. They also factor in what kind of surgery it is and how long it'll take.\n\nOnce you're under, they're watching your heart rate, blood pressure, breathing, and sometimes brain wave monitors. If your blood pressure spikes when the surgeon makes an incision, that tells them you might be processing something even if you're not conscious of it, so they adjust. They're constantly titrating, which is a fancy word for giving a little, watching what happens, giving a little more or backing off. For inhaled gases there's a concept called MAC which is basically the concentration at which half of people won't move in response to a cut, and they use that as a reference point.\n\nSo it's not a fixed dose.

People mix the two painkillers up constantly and assume every bottle on the shelf works identical.\n\nwhat actually happens if you take a pile of them is the stomach lining loses its protection from acid because the drug blocks the chemicals that normally keep it intact. You can end up with ulcers or bleeding that sneaks up on you. The same blockage happens in the blood vessels feeding the kidneys so they do not get enough flow and filtering slows down or stops working right for a while. *kidneys take more of the hit* than the liver does here. I have read cases where someone popped a huge number and the blood work showed a small bump in liver enzymes but it settled once they stopped. Full liver failure from ibuprofen by itself seems pretty uncommon, or at least that is how it looked last time I checked around on this.\n\nThe body just routes the leftovers differently so you do not get that sudden glutathione crash and the cell death that follows with the other stuff. High doses still stress the organs that handle waste and blood flow regulation more than they fry the liver tissue itself. That is why the warning labels talk more about stomach and kidney problems for this class. Taking extra will not magically switch it over to liver mode.

It mainly targeted the United States and countries allied with it, but it also killed many Muslims and people in other countries.\n\nThe group was founded around the late 1980s by Osama bin Laden and other militants who had fought Soviet troops in Afghanistan. After the Soviet Union left, they did not simply go home and stop fighting. They decided that the United States and other governments were the main enemies. Their reasons included American troops and bases in parts of the Middle East, support for Israel, and American backing of governments they hated. They also had a much bigger religious-political goal: they wanted a strict version of Islamic rule across a huge area, and they were willing to kill ordinary people to pursue it.\n\nOn September 11, 2001, al-Qaeda carried out the attacks in the United States where hijackers took control of four passenger planes. Two planes hit the World Trade Center in New York, one hit the Pentagon, and one crashed in Pennsylvania after passengers fought back. Nearly 3,000 people were killed. That made al-Qaeda famous worldwide, but it had already attacked American embassies, a warship, and other targets.\n\nThe group was not a normal army with one big headquarters and soldiers wearing uniforms. It helped train, fund, and inspire smaller groups in different countries. Those groups did not always obey bin Laden directly, but they shared enough of his ideas to call themselves allies or branches. This made al-Qaeda more like a network than a single gang under one roof.\n\nIts propaganda claimed that killing civilians was allowed because those people supposedly belonged to enemy societies. That is not a rule that ordinary Muslims accept, and al-Qaeda's interpretation was rejected by many Muslim scholars and governments. \"Islamic\" in the name of a violent group does not mean the group speaks for all Muslims, any more than a criminal group using a Christian symbol would speak for all Christians. The vast majority of al-Qaeda's victims were Muslims anyway.\n\nThe United States invaded Afghanistan after 9/11 because the Taliban government there had allowed bin Laden and his organization to operate from the country.

The official reason was that some of the signatures they collected from voters to qualify were deemed invalid or fraudulent. The candidates and their supporters said the signature verification process was rigged specifically to keep them off the ballot, and honestly most outside observers agreed that the standards being applied were inconsistent and politically motivated.\n\nThis kicked off a series of protests in Moscow starting in July and continuing through August. The first ones were relatively peaceful, just people gathering and demanding the candidates be allowed to run. The authorities responded by banning the protests and then sending in riot police and the National Guard, which is basically a militarized police force that Putin created a few years earlier. They started making mass arrests, sometimes grabbing people at random off the street, beating them with batons. There were videos everywhere of police dragging people into vans.\n\nOver the course of several weekends they arrested thousands of people total.

The elections happened in September with the opposition candidates still excluded, and the pro-Kremlin candidates mostly won, though United Russia, Putin's party, actually lost a bunch of seats compared to before, partly because of a smart voting strategy Navalny pushed where he told people to vote for whichever non-United Russia candidate had the best chance in each district.\n\nSo basically the whole thing was about whether opposition politicians could participate in even local elections, the answer from the government was no, and the public response was big enough to get attention but not big enough to change anything.", "words": 440, "prompt": "floor", "seed": "eli5c-2892|qwen/qwen3.8-max", "target_words": 438, "draws": 4, "post": {"curly": false, "double_space": true, "ellipsis": false, "em_dash": false, "en_dash": false, "lowercase_para": false}}
