  • You realize that even with a laws-of-physics-perfect-theoretical camera in order for a fighter jet to be even a single solitary pixel it would need a primary mirror well over twice as wide as the SpaceX “starship”, right?

    Like launching a keyhole style satellite would require a Sea Dragon just for one pixel per ten by ten meter square.

    I get that space is big and most people really don’t understand scale, but there is a reason that optical spy satellites are well below the ISS in some of the lowest stable orbits for such large satellites, about a hundred and twenty times closer than geostationary to orbit.

    Suffice to say no one has come close to trying this, and it would be the wrong solution to the problem as compared to just throwing 100 times the money to the NRO and letting them throw up keyholes like they were cubesats, and that still would only get you limited areas every few minutes.

    All of this doesn’t effect any of the other problems, like trying to get this imaging down to data centers, doing image recognition on such a massive data stream in near real time, or that it can be completely eliminated in a half hour with a few old fighter jets and some of the anti-satellite missiles everyone down to India has whole stockpiles of.


  • I hate to burst the bubble on the Elon Musk school of ‘what use is stealth when everyone has cameras’ way of thinking, but even neglecting that if you are in a conflict where you are using this sort of fighter jet then your satellites have been shot down by the enemy’s air force, satellite imagery and the laws of physics just doesn’t work that way outside of sifi.

    The planet Earth is just too damn big for that sort of thing. The NEO can give you a decently high res photo of a place maybe several times a day, and even that means prioritizing using said satellite to look at that one single place on Earth.

    More practically you get once or twice a day, with the resolution necessary to pick out a jet being limited to the small area you picked out ahead of time, and of course the enemy knows to within a half and hour or so when that picture is going to be taken.

    AI guided TV missiles have been a thing since the 70s, and still remain only really practical for targets that can’t move very much. Little real world things like size of optics, stability of optics, resolution of optics, atmospheric distortion, cloudy days, night, mountains, horizons, etc, have kept this a non-answer to an unsolved physics problem for quite some time.

    This isn’t to say that the military isn’t an incredibly good way of making public money disappear or that the US has it monitory priorities in order, but rather there is very much a reason that the Inspectors General report into this very project several months ago came back with Yes, this is the most cost effective solution for the military to achieve its goal of providing credible deterrence and preventing a war in the Asia Pacific region.

    Moreover I would argue that the US has never lacked the money for healthcare or schools because of the military, and that if Trump desolved and fired the entire military tomorrow it would still not spend more on schools or healthcare. Rather I would argue that the US is ideologically driven to generally avoid taxing the people with all the money who own its leaders, it by and large does not want that money bring spent on things that benefit poor people, and many of its voters would rather burn the whole thing down than accept a dime going to a black or brown person.


  • It’s worth noting that this project for a F22 replacement has been known to be in development for quite a while now, so this is less a Trump thing than someone at the Pentagon pulling him aside and changing the name to make it less likely he will kill it when Putin or Xi Jinping remember they can just ask him to and he will.

    Here is an excellent as always Perun summery on the US, EU, etc projects as of a month ago, but basically it doesn’t matter how good the F22 is over the pasific if China just shoots down all your tankers and carriers from well out of range, so it’s high time for a pasific range capable fighter.

    Shame it’s going to Boeing though.




  • Counterpoint, I grew up in a smallish town in Idaho and was still absolutely surrounded by Democrats. State wide, only sixty percent of the voting age population actually turned out, and of those one out of every three people voted against Trump.

    Hell, Democrats outnumbered Republicans in some countries and again, this is fucking Idaho.

    This means that if you talk to an a Idahoan at random, there is a more than fifty percent chance they either largely already agree with you, or they are largely insulated from and not paying attention to politics and thusly susceptible to being swayed with the right approach and concrete examples of what Trumps doing to fuck them and their friends over specifically.

    Left wing ideas and policy are still far more popular among the general public, which is why Republicans have to lie about them constantly.

    Look for your local anarchist bookstore, look at what your counties Democrats actually organized, especially things like local pride events, show up, and network/make friends.

    As is fun to note, there are more Democrats living in Texas than New York state, so the idea you should just give up on finding any around you because you live in a red state instead of one where the numbers are reversed is honestly rather absurd.



  • From my youtube understanding the 737-800 doesn’t have a RAT, instead using a battery system to power the DC bus, some controls, and minimal avionics. Also for some reason the FDR and CVR are powered only from the AC buses, and so would not have power in a two engine out scenario until the pilots manually started the APU and it came online. It also predates the requirement for said systems to have an independent backup battery.

    This means things are still consistent with a staggered double bird strike or with a single bird strike followed by the pilots shutting down the wrong engine as well as some of the more out there theory’s.

    Investigators might still be able to recover enough switch positions to figure out what happened in the air, but it’s going to be a hard investigation.

    The major takeaway and factor that turned this from a major incident into a catastrophic one however is still that putting the localizer on a concrete reinforced berm for typhoon resistance is a major safety hazard.


  • Hopefully, but I worry no small part of it at the moment is just that we’re too small to be worth the bother. If the fediverse grows big enough to matter, well I worry about what dedicated teams of people working a full time job could do. One or two people can easily run a few dozen active accounts, which in turn could easily dominate conversation on an instance.







  • Why should I be afraid of a foreign company learning my information, and instead trust a local one that proudly sells it on the open market to anyone that wants it?

    This proposal puts no fetters on what information amarican companies gather or sell to the Chinese.

    And yes, the largest nation in the world definitely stole all their technology, all thouse technology transfer agreements, companies outsourcing their manufacturing lines to it, and of course the hundreds of billions it’s government poured into the R&D of new energy technologies at a time when most western countries were slashing or eliminating their own subsidies and investments had nothing to do with it. Nope, none at all./s

    Don’t get me wrong, fuck the CCP. They are authoritarian imperialists who constantly cultivate racism and xenophobia while openly punishing anyone who speaks out against them, and are far, far more interested in protecting the power of the party’s leadership than even appearing to try and appear actually left wing, but this does nothing to protect american consumers.

    The only practical effect is to shield amarican manufacturers from competition with companies that have not colluded to focus exclusively on the largest, highest profit gas guzzlers they could fit on the roads during the last two decades the instant it looked like their customers might actually have had an option but to bend over and take it.

    Chrysler and GM could have focused their efforts on building cheaper EVs instead of half assing compliance cars and then selling them for enough to ensure that sales would never get big enough to divert manufacturering lines from their high profit margin Trucks and SUVs, but instead actually chose not to.

    Now the government is actively protecting them from competition on a thin pretense, and say it with me now, we know it’s a thin pretense because the government has no problem with Amarican, european, Japanese, and Korean companies doing the literal same exact thing and then selling the same recordings to the Chinese government.

    If the government was actually even the slightest bit concerned about amarican car buyers privacy, it would not allow a company like Tesla where employees regularly pass around clip compilations of the funniest things they’ve seen on the car’s internal cameras to have cellular modems, internal cameras, or over the air updates.

    Instead it says if you want a car with bluetooth speakers or over the air security updates, you must buy the land yacht from the good amarican company that just donated to our campaign and is making a killing on the margin shortly after it looked like even a hundred percent tariff might not be enough to protect amarican car manufacturers from the consequence of their own direct choices.


  • Boy, it sure is a good thing that there is only risk from low cost Chinese vehicles, could you imagine if security researchers had been demonstrating that these theoretical attacks have actually been trivially done on American and european vehicles for decades now? Thankfully all other car companies are bastions of cybersecurity best practices, near impossible to hack or slip malicious code into via an over the air update.

    Also could you imagine if a Chinese company could spy on you directly and learn personal infomation though your vehicle, instead of buying that same information on the open market from a good american car company instead? The horror.

    It’s just a convenient coincidence that this comes at the same time as the american car industry risked actual competition with competitors that didn’t spend the last two decades building half assed compliance EVs while focusing on selling the public on the largest, highest markup truck and SUV that can still theoretically fit on the road.

    Ohh well, guess Amaricans are just going to have to pay three times as much for new vehicles than the rest of the world for vehicles with similar manufacturing costs, wouldn’t want to risk GM or Fords profit margins after all.

    I sure am glad that the government may not be willing to provide social housing without a five year wait list while you to live in a tent under the freeway and get all your worldly possessions, photos, and documents thrown out by police, but is always proactive about ensuring that billion dollar companies never have to worry about facing even the slightest consequence of their own active decisions to undermine the fight against climate change.

    Biggest /s possible.




  • Ya, I agree people should be getting a fair wage, I just don’t see how a tax on products sold more directly helps with that in this case. People will just shrug, say it’s still cheaper than the same model on Amazon, and buy it all the same. A company is always going to try and pay the lowest price they can while pocketing the rest, and the best you can typically do is help the workers bargain for more.

    I mean things like BDS can work, but they have to be targeted very carefully and specifically to get a board of directors to take a specific action, and the wider the net you cast the more dilute it gets and the more likely companies will call it the cost of doing busines.

    US condemnation of the system would probably also have a bit stronger effect if it wasn’t using the same system of minority prison labor farmed out to various companies and saying it’s perfectly ethical fine so long as the people you arrested on thin pretext for race get a few dollars an hour that they then spend right back at the prison.

    Put another way, if the EU put the same import tax on products and companies that made things in Mississippi on us because of the general prevalence of undocumented black prison labor in the region, do you think that the we would suddenly change things?


  • This predisposes that much more expensive one sold locally is not also the same model and manufactured in the same factory. When so much of what is sold at Amazon or Walmart originates from Alibaba or bulk orders from said factory, the only difference in the exploitation is if Bezos gets a cut on top.

    Functionally, I think you’ll have a lot more luck pushing for and requiring supply chain transparency from the Amazons and Walmarts of the world, or directly using national economic and political pressure, than focusing on increasing the cost on the small market of people going direct to the source.

    Admittedly though this is less true as it has become more widely known that Temu and the like have the same product selection as Amazon, and indeed that seems to be the actual reason this legislation has been proposed.

    Nevertheless I can’t see the US government taking slightly more of a cut having much of an effect when most of the products which heavily involve Uyghur labor are meant for internal use or export to the third world. You would need to propose serious practical consequences for the leadership of the CCP and follow though on those consequences to force external end to a political project that’s popular domestically like this, or at least a very closely and precisely targeted BDS campaign, and not just continuing business as usual but with higher taxes.


  • I’m more skeptical than most that self driving will be properly solved anytime in the next few decades, but I really doubt the article’s claims that it will be able to claim much modeshare from bikes and transit.

    Firstly, we already have and have had autonomous vehicles for nearly as long as we have had vehicles, their called taxis and carpools. Making these potentially cheaper, though in practice I doubt it since a taxi’s costs are spread over all its users while a car has to be paid by just you, does not change the fact that they are less convienent than being able to show up and hop on like a bus, or the immunity to traffic delays of rail. Indeed the proposed system of distant out of city parking lots would take more planning than just parking your own vehicle today in most places, as you have to call or order ahead with AVs to have them ready for instead of waking to your car and jumping in. Similarly, getting stuck in traffic does not get much more fun simply because someone else is driving, especially if you can’t even talk to them.

    The arguement for them replacing bikes is even worse, because one of the few things proper self driving vehicles are already pretty good at thanks to 360 ultrasonic and lidar sensors at is not blindly running down bikes, and a future with widespread adoption would also imply that most other vehicles have similar driver assistance tech, and as such more people will feel safe biking even in places with shit bike infrastructure. Meanwhile most people who were going to use a bike for a trip will not choose driving over bikeing just because they can get someone else to come pick them up.

    I could see it having an effect on modeshare in places with really shit and infrequent transit, but the whole point of rapid transit is that it is more rapid than taking a car. If your transit system is slower and worse than waiting ten minutes in the rain for an Uber, fix your terrible transit system, because that really should be a low bar to clear.
