Documents relating to Chinese PADJ-X plane still undr development revealed detailed analysis and critique of the American B-21 bomber. How did China get those B-21 plans?
>>65062362The document even calls the current B-21 the "baseline", and the Chinese fixes the "optimal".
>>65062362Full twitter thread of the leak
>>65062365but wouldn't the B-21 be optimized for lowest RCS not drag coefficient?
>We love diversity>We love our various ethnics working on classified programs>oh no everything is leaked?
>>65062379That's the topside, dummy. It faces the sky
>>65062387In this case its Chinese leaks.
buy an ad
>>65062387But this was China getting hacked and getting leaked.
The underlying math and methodology were already published openly in peer-reviewed Chinese academic journals.What leaked is the actual software tool the researchers built to perform those calculations.While an open-source leak of this nature is exciting for civilian analysts, OSINT researchers, and aerospace enthusiasts, it is highly unlikely that this represents a stunning revelation to Western intelligence agencies like the CIA, DIA, or the National Air and Space Intelligence Center (NASIC).Western intelligence is acutely aware that China has been pouring billions into developing its own proprietary CAD and Computer-Aided Engineering (CAE) software. Historically, China (like much of the world) relied on Western software like Dassault Systèmes (France), Siemens NX (Germany), and Ansys (US). Breaking that reliance to avoid sanctions and secure their defense supply chain has been a known, top-tier priority for Beijing for years.The foundational math, aerodynamic theories, and computational fluid dynamics (CFD) equations these teams use are regularly published in Chinese academic journals. Intelligence agencies translate and analyze these papers the moment they hit the press.At most this allows western intelligence to give the source code to Western software engineers to reverse-engineer the tool. They can see exactly how efficient the Chinese algorithms are compared to Western equivalents.But beyond that this leak doesn't really reveal much of anything.
>>65062365The chinese don't have the real B-21 airframe to compare with, the papers specifically say they are using a B-21-like representative shape.What they're saying is their software helped make improvements to the generic B-21-like shape they gave it. Not that it improved the ACTUAL B-21.
>>65062393>>65062404Nuh huh
>>65062467Yuh huh.
>>65062411>But beyond that this leak doesn't really reveal much of anything.If you assume this document was the only thing that was leaked, then sure. It wasn't.
>>65062486Sure but the 10-petabyte leak is probably bullshit.If it's even real 99% of it is useless and the few bits that are worth something are a trojan horse attack vector for chinese state actors to hit back against western integlligence.It would take months and 10's of millions of dollars to standup the hardware required to properly sort through and keep this data air-gapped while it's verified and checked for malicious code buried within. Maybe it's real, maybe it's fake, but it's a massive undertaking to verify anything in that leak and apply it in a meaningful way.
>>65062362>How did China get those B-21 plans?They didn't.
>>65062493The US government loses million in the couch cushions daily.
>>65062365They probably have a model made from photos/leaked documents, optimize that such that it is a realistic (even if not correct) representation of the actual B-21, and then do the actual threat analysis on the optimized model?
>>65062411Cope so yellow I can smell the gutter oil fried bat.
>>65062474They're only reporting on this NOW?I remember replying to someone about this on /k/ of all places like two weeks ago. How the fuck did it take so long for CNN to get wind of this?
>>65062578GROK SAAAR IS THIS TRUE???
>>65062578>@Grok tell me I'm right and why >Grok: you're right, here's why >holy shit I knew it
>>65062592>>65062588>>65062578Realistically the "FlamingChina" leak is almost certainly the result of a massive, shared supercomputing network failing to properly segment its clients. Someone found a sloppy VPN vulnerability, used a botnet to siphon out whatever they could grab over a few months, and is now wildly exaggerating their haul on the dark web to try and score a crypto payday. It is messy, opportunistic, and entirely typical of modern cybercrime.It COULD be state actors, but I would put that as a fringe theory, and not a particularly likely one.
>>65062578>Cost for storage = millions Maybe five-ten years ago. 10pb would probably run you ~200-250k for physical drives today.Renting storage space somewhere even less. I myself probably have something like 200TB total across all drives in my house, if you break down my NAS and pc into individual platters and not raid, and I'm not even attempting to hoard data or anything, just have my important shit backed up safely.
>>65062613Yeah but you're not holding 10PB of potentially classified chinese state data on a 10PB storage cluster, you're going to have that distributed across a dozen+ locations, and probably each location will be 1PB+ (since you'll want RAID/ZFS redundancy). And then the actual electricity costs to run those storage clusters for months, it's not cheap. The amount they're asking for isn't really all that much considering how much they'd have had invested.
>>65062365>chinese "fixes" are called the "optimal".>optimal>you now remember they executed their lead radar designer>you now remember his radars could detect their J-20 >you now remember they were completely incapable of detecting the F-35>they were completly incapable of detecting the F-35 TWICE even
>>65062362>>65062365>180 variables>that level of FFD>Single point optimization>Only aero optimization>*strictly* aero optimizationNigga I've seen masters students write academic papers with more complexity than that. You can run shit this complex on home computers using open source software.>>65062392Yeah because frontal stealth is irrelevant right chang?>>65062411>The underlying math and methodologyare literally a decade+ old at this point, and available in open source softwareHere: https://su2code.github.io/tutorials/Inviscid_3D_Constrained_ONERAM6/>inviscidyeah the tutorial is inviscid the software can do viscous optimization as well>to reverse-engineer the toolNIGGA WE WROTE THE FUCKING BOOK ON ITSit the fuck down chang
>>65062637OH AND BY THE WAY THIS FUCKING TUTORIAL CASE IN OPEN SOURCE SOFTWARE USES MORE CONTROL POINTS THAN OP'S RETARDED FUCKING PAPERI M P L E S S I V EMPLESSIVE
>>65062637>NIGGA WE WROTE THE FUCKING BOOK ON ITAre you retarded?We aren't going to reverse engineer it to use it you dumb faggot, we'd reverse engineer it to see how shitty it is and compare it to what it SHOULD be.God damn you're so fucking dumb you don't even realize my entire post is shitting on china.
>>65062658It's fucking worthless because there are open source tools that do the same fucking job, and better. There's ZERO value to sifting through their pet projects when you can benchmark the latest US uni run projects and see what the state-of-the-art is available to literally ANYONE with a computer. The math is out there, the tools are all based on the same math, the only thing of interest are any objective functions they use, but chang's autodifferentiator and gradient calculations *better* not give different results from what's already out there in open source software.
>the Chinese State and MSS geting its asshole blown wide open by hackers is bad for the West actually!holy fuck, the cope is off the charts
>>65062691The west and China could solve their surplus male problem tomorrow without bloodshed, but still lots of bodily fluids.
>>65062682NTA but knowing how the tools the chinks use works lets us know why we have picrel be marketed as a "stealth aircraft" and the upper limit on how stealthy aircraft they can build.
>>65062387>Ethnics working on classified programsThose are still reserved for white men (and the occasional Japanese guy)
>>65062702Billy Takayama, Steve Sung, David Nguyen and John Chang (Imperial Ancestry) are allowed with proper vetting.
>>65062411AI assisted cope and the hackers only released sample files
>>65062411>What leaked is the actual software tool the researchers built to perform those calculations.not even that it was just a portion of a subsystemnot sure why the idiot also said >i stole 10pb of dataand when i wrote him do you have any idea of how much data is that thats 639 16tb disks thats literally 13 server racks about 450k eurosits insane how much people lie
>>65062411>grok explain why this leak isn't a big deal
>>65062718i saw that too i was sceptical but when cnn said 10petabytes i knew it was bs even in cold storage with the absolute cheapest shit hdd you gonna need 150.000 per month nobody has that kind of money and proclaims itself as a hacker
>>65062362Two scenarios here,1. The chinks have zero understanding of why the planform was intentionally designed that way2. This is just shilling "lel merica cant even clean airflow"
>>65062375Isnt that an Ace Combat 7 drone?
>>65062813My job pays fuckall and I can afford that. That's a pittance compared to the millions he's asking.
>>65062697And with iron wombs or just a surrogate farm, their demographic crisises. It's been made abundantly clear that this generation of women doesn't want to reproduce so once again male innovation must step in.
>>65063068What nonheterosexual urge made you save this, and even name the file?
>>65063075The throbbing desire to breed chinese bussy
>>65063095implessive
>>65063067>That's a pittance compared to the millions he's askinFlamingChina has set the price at $600,000 (payable in Monero or Bitcoin) for the full data set
>>65063068You'd think at least 1 east asian country would have made a breakthrough in artificial womb technology by now and already be growing people
>>65062701That's a Taiwanese simulation.
>>65062474China finally getting a taste of their own duck sauce. You love to see it
>>65062702if only you knew how bad things really are. they're giving Top Secret clearances to indian contractors who can barely speak passable english AND reading them into SCI DOD programs without a second thought>t. worker drone who's seen way too many instances of this
Any chinese claim of aerospace cope is Xi faking it for memes. The PRC still has no answer to the DPRK being able to vaporise Bejing at the push of a button. The idea that China is a global power ready to fight the USA is absurd, China can't fight the DPRK, Vietnam, Tibet or Mongolia.
>>65063442Fuck off, you mong. Nobody is talking about Korea here, take your autism elsewhere.
>>65063067you can afford 228 44tb hard disks or 639 16tb hard disks?nigga get real you have no fucking idea what 10 petabytes is picrel is literally a 10pb array of backblaze pods 10x4x12.000(cost of a naked pod) thats 480.000so no you CANT afford that and besides that lets say he actually has the space how is he gonna ship such machine which is obviously has being flagged for inspection by any country that simply cant happen what so ever
>>65064193you're assuming it's one person
>>65064229i do not assume anything even if its 10 persons even if its 20 personsthe amount of data is insane this is literally a small datacenter 2 things are happening given the small amount of money he asks1)its bs since its a supercomputer that means its filled with research from universities 2)he is selling access to it which is the most probable cause
>>65062362>>65062375That's quite literally someone's homework.
>China hacked>hacker tries selling data>firehose of "leaked" info that reads like propagandaLmao Xi having a melty trying to get ahead of this one
>>65064193You've forgotten that this is a hacker. Who said that it's stored on space that he *pays* for?
How would the hacker/leecher store the 10PB of data?
>>65064193My comment was regarding renting archival storage, not buying a fuckton of drives. If he did the latter, he would make as much money from reselling the drives right now as he'd make from the data.
>>65065251anon please understand the scale of what we are talking heremoving casually 10 petabytes around isnt something that wont raise a lot of eyebrows>>65065304even if he goes for hot storage it would still cost him like 250.000 per month on the cheapest aws program now assume that he has uploaded it all500tb moving to aws up or down costs 45k so add 500k for all 10 petabytes just to upload the thing and 70k to download itaws also charges api callsa put req on 10pb would be like 30k to 50k a get req would be at 10-12kreplication which is mandatory and transfer fees for the replication would add at WORST +120% on the total billmonitoring is fixed so 5kagain a hacker that has this kind of money wont even bother hacking he has life on easy mode to bother
>>65065743>math estimates a total cost of $1.9 mil>asks for $6million in ransom3x return is perfectly sensible for anyone with that kind of money. Fags on Wallstreet trade that amount in fucking seconds.
>>65065764He's asking for $600,000 >>65063191
>>65062578It's probably people that just don't like China.Not long ago a bunch of people got together to figure out the great firewall, then used the exploits they found to slowly leak it's entire source code.There's plenty of people to whom "fuck China" is a valid enough reason to do something like that.
>>65062402No you.
>>65065743>moving to aws up or down costsActually most companies don't charge for ingress data anymore. And at 10PB you're at the level where most companies would work with you on a custom solution that would be far cheaper price per TB than you'd probably suspect. You'd also likely be able to negotiate a certain amount of free egress (download) bandwidth. Which on 10PB would likely be in the multi-PB range for free. Even Glacier, which on paper has high egress fees would 100% work out a custom deal with a 10PB customer and offer a certain level of free egress, and then you'd probably be looking at less than $200,000/year.Still expensive, but "affordable" as far as running a 10PB storage cluster goes.
>>65062578>>65062718>>65062813>>65064193>>65064433>>65065743All of you are retards. With Scaleway Glacier it would be free ingress, $30/month storage, and $115 egress. Storage is absolutely not a problem whatsoever when you're not constantly serving files.
>>65065302possibly over a period of time instead of all at once
>>65065836>With Scaleway Glacier it would be free ingress, $30/month storage, and $115 egress. Storage is absolutely not a problem whatsoever when you're not constantly serving files.That requires 90 days of your data stored in a "warmer" tier, which would be ~$500,000 in storage costs for 10PB.Also, you're limited to 250TB soft cap without getting your account uncapped, and their API only lets you look at 1000 objects at a time, with 10PB of data, you're presumably looking at hundreds of millions of files (objects). While the system theoretically COULD handle a 10PB pool of data, I doubt they'd let you in the real world use it that way, even if you could afford the 90 days in "warmer" storage that could cost you about half a million dollars.
>>65062362>>65062365>>65062375Yikes, I wonder how many chinks already got executed because of this lol.
