You know the rescue operation was a massive success when all the usual suspects come out vehemently insisting it wasn't.

“Hit ’Em Harder” Submarine USS Harder Found Intact After 80 Years Beneath the Sea USS Harder, the famed “Hit ’Em Harder” submarine of World War II, has been discovered lying upright and almost completely intact more than 3,000 feet deep off Luzon. Found by the Lost 52 Project and confirmed by the U.S. Navy in 2024, the wreck shows a large blast hole just behind the conning tower—the point where Japanese depth charges struck during her final battle in 1944. She rests quietly on her keel, surrounded by coral and deep-sea life, her steel hull still clearly shaped after eight decades in the dark. Commissioned in 1942, USS Harder became one of the most successful Gato-class submarines in the Pacific, sinking five Japanese destroyers in five patrols under Commander Samuel D. Dealey, who earned the Medal of Honor for her daring missions. On 24 August 1944, she was lost with all 79 men aboard after a fierce counter-attack off Luzon. Now resting in the silence of the deep, Harder remains both a powerful relic of naval warfare and a lasting memorial to the fearless crew who lived—and died—by her battle cry, “Hit ’Em Harder.”

Data centers in orbit? Of course that’s your contention. Of course it is. You just finished watching a Scott Manley video on radiative heat transfer and now you think you’re gonna disrupt AWS with a few solar panels and a rideshare slot. You’re gonna believe that right up until next month when you crack open DeWitt and Incropera and start throwing around σT⁴ like you just invented radiation physics, quoting emissivity tables for polished aluminum like they’re forbidden knowledge. Then you’ll finally open SMAD and realize your radiator isn’t some static plate glowing into the void. It’s a dynamic structure with a wicked case of thermal flutter reminiscent of Hubble’s arrays. You’ll be quoting beta angles and Earth albedo coefficients and wondering why your deployable array grenaded in vibe when the first bending mode clocked in at 38 Hz instead of the 50 Hz you promised in CDR. After that you’ll get real ambitious, quoting Johnson and Fabisinski on inflatable polyimide PV structures, pretending you actually understand what happens when your 25-micron Kapton sail is tensioned off a Toray T1100G Cycom 5250-4 boom that has been sun-baked at 120 °C for six months in LEO. You’ll cite “areal density optimization” like gospel while your resin creeps, your modulus drops, and your perfectly flat film turns into a potato chip. "Well, as a matter of fact, I won’t, because launch costs are about to fall another order of magnitude once Starship hits cadence. The cost per kilo will—" Drop by tenfold and the economics flip. Yeah, I’ve heard that one. The Wired 2012 quote, “You wouldn’t build a Boeing 747 and throw it away after one flight.” I remember. I even asked him about that over lunch once, whether the market was actually elastic enough to handle the supply increase from reusability. Turns out it wasn’t. Non-Starlink launch mass in the United States grew at 13.7 percent CAGR from 2015 to 2023. Payload demand didn’t scale with flight cadence, so prices didn’t collapse, margins just swelled. That’s why they had to invent Starlink. When the market can’t absorb your rockets, you start building your own payloads. Is that your thing? You read some Marc Andreessen “American Dynamism” manifesto and suddenly start ignoring the engineering realities? You start throwing around a few buzzwords to impress the Twitter anons and earn some street cred for having a contrarian opinion? One, don’t do that. Two, you dropped a 500-thousand-dollar seed check on a concept that could have been debunked by a dollar-fifty worth of tokens from Grok. "Well, at least I’m a capital allocator. We’ll be skiing in Hokkaido while you’re doing bolt preload calculations for some bridge somewhere." Yeah, maybe. But at least I won’t be unoriginal or anonymous. I’m out here asking why the hell we’d melt the brains of a thousand aerospace engineers just to save four cents per kilowatt-hour on solar electricity. First principles isn’t about getting nerd-sniped by a shiny-object problem. It’s about asking whether we should be solving that problem at all. But hey, if you’ve got an issue with that, we can always take it up with E.

Talk about phoning it in... Probably worried that if someone did it for real they'd write something not PC so they just got vinyl stickers or some shit.
absurd detail to notice here but these are stock graffiti fonts (all the double letters are the exact same). they didn’t even get someone to actually draw any of this.

Since the Zumwalts displace 15,000 tons, 5K more than the traditional definition of a "heavy cruiser," and mount what are technically the biggest guns afloat on a surface combatant today (155mm) they should be classified as battlecruisers. In this essay I will-

9/11/2001. The past 25 years haven't actually been part of the 20th century, but rather the 21st. I will also be willing to accept arguments that the 20th century ended with the fall of the USSR, and that the "Long 21st Century" started with the 1st Gulf war.
If the long 19th century was 1789-1914: When did “the long twentieth century” end?

This is what criminal negligence (on the part of the boss) looks like.
dude cut my LOTO off without contacting me or our boss. He just got told to not do it again. i may be over reacting but seriously he should have been reprimanded

Even if not to the level John describes, war fighting requires physical effort even when it's all done with computers. And the epidemic of "rules for thee not for me" from an ever-expanding flag officer class must also be put to an end by making em lift their own weight.
Can I say something without everyone getting mad? We 💯 need Navy SWOs to meet combat standards too. Let me explain. I don’t work out much anymore, but once upon a time, I had 8 varsity letters and roomed with future Navy SEALs. I’ve hiked hundreds of miles in the mud and rain and swam in storms. Not anymore, but once upon a time, I did. Want to know the workout that kicked my ass more than any of them? Emergencies aboard ship! You can be overweight or not up to male physical standards 99.9% of the time on ships, but when a fire breaks out or a pipe bursts in the Engine Room? It takes massive amounts of strength over hours to close watertight doors, haul gear, haul casualties, move cargo, climb ladders, turn massive wrenches, swim out of flooding compartments… Most intensive workouts I’ve ever had aboard ship, and the major emergencies I faced were mostly in calm weather. Fighting a fire at sea in a storm I can’t even imagine. Give me 40 Hercules, and I’m sure I’d push them all past exhaustion. And the dark secret is these emergencies can last for hours. WHICH means you have to rotate out the guys doing the hardest work, WHICH means every single person aboard from dishwasher to XO will be pushed to exhaustion. Those people— regardless of whether it’s due to their eating habits or gender— who can’t meet strength requirements equivalent to a front-line army grunt in the front lines are worse than dead weight. They are a liability to the entire ship during a massive emergency. And one liability that sinks a single ship in a carrier formation puts the entire formation and the carrier’s 5,000 crew and air wings at risk. And the loss of ONE carrier puts the entire region of the globe in peril and every soldier and marine operating there. Surface Warfare Sailors MUST meet Combat standards too… even if they tell you “I’ve served aboard warships for 25 years and never got pushed to exhaustion.” Great. That’s true in peace. Surface warfare is easy in peace. But in war? Saving a ship on fire and sinking requires Special Forces-level strength. That’s just a fact. And we better start putting real tests of strength and stress and risk back into regular emergency drills at sea. At sea you fight like you practice and right now only the most hard charging Chiefs push their SC teams to exhaustion while most of crew goes nowhere near the simulated fire. Most Navy officers haven’t seen emergencies like I have because their ships are in much better condition than US Merchant Marine ships… but I have. I remember my first big battery room fire, my best trained guys showed up and I made the little guys switch out for lesser trained BIG guys. That’s nothing I was ever taught. It surprised the heck out of me during the debriefing because I didn’t even remember giving the order. I did it because some things you can’t be taught. BIG STRONG guys on point in a ship fire is just something that’s obvious to everyone who has been there. P.S. don’t take my word for it… all of this - the need to train EVERYONE aboard a combat ship to exhaustion - is in the after action reports from the USS Forrestal fire in 1967. The 1990 Navy combat standards included all the above in it.

Definitely fits in with my experience. Analytical methods in the complex plane and quaternions were simply overly onerous math for me with little application.
Douglas Hofstadter wrote about his experience of running up against an “abstraction ceiling” in his own brain while pursuing a PhD in mathematics. As Hofstadter describes, the abstraction ceiling is not a “hard” threshold, a level at which one is suddenly incapable of learning math, but rather a “soft” threshold, a level at which the amount of time and effort required to learn math begins to skyrocket until learning more advanced math is effectively no longer a productive use of one’s time. That level is different for everyone. For Hofstadter, it was graduate-level math; for another randomly selected person, it might be earlier or later (but almost certainly earlier).

Hey. Commercial fisherman here! 👋 That boat was not being used to fish and you can tell by the fact that it was running full tilt, with four high performance motors at night. Hope this clears up any confusion you lubbers have over that narco drug boat!

I would love for President Trump to clean up cities like Chicago. He proved in DC that enforcing the law actually WORKS. But Chicago isn't a federal district. Trump must find a 100% CONSTITUTIONAL way to do it, or else he would open the doors for real tyrants down the line. Or, even better, how about the Democrats controlling these cities put their constituents above politics, learn from Trump’s success, and enforce their own laws!

I love this kind of discourse, because what the hell is the point of measuring the *water consumption*? People act like water is this precious finite resource which is destroyed by use, instead of yknow used as a heatsink and released into the environment slightly warmer.

Google publishes a paper showing that its AI models only use 0.26 mL of water in data centers per prompt. After, this article gets published: "Google says a typical AI prompt only uses 5 drops of water - experts say that's misleading." The reason the expert says this is misleading? They didn't include the water used in the nearby power plant to generate electricity. The expert, Shaolei Ren says: “They’re just hiding the critical information. This really spreads the wrong message to the world.” Each prompt uses about 0.3 Wh in the data center. To generate that much electricity, power plants need (at most) 2.50 mL of water. That raises the total water cost per prompt to 2.76 mL. 2.76 mL is 0.0001% of the average American lifestyle's daily consumptive use of fresh water and groundwater. It's nothing. Would you know this from the headline, or the quote? Why do so many reporters on this topic do this?
