  • Its not an equally slow CPU. These boards support Xeon CPUs that first launched 11 years after DDR3.

    The implication is that there are users needing large RAM footprints that aren’t CPU bound. The hit in performance on the RAM isn’t significant enough to justify spending orders of magnitude more for modern DDR5 which is in short supply.

    In computing history there’s precedent for this. Amiga computers had a small amount of “Fast RAM” which was extremely expensive, but the CPU could address a second bank of “Chip RAM” which was significantly slower but much much cheaper.

    We could see this idea return in modern computers.









  • Do you not remember what happened after the the acquittal of the officers that brutally beat King? The LA riots happened. The video was what catalyzed so many to action even when the truth of police brutality was well known before that.

    This is true of Eric Garner which was also caught on video and lead to large demonstrations.

    And again with Philando Castile where the video showed Castile totally complying with officer orders, yet was still shot dead by that police officer. Again demonstrations against police brutality.

    Its the video that makes people take notice. Sadly, it doesn’t sound like we have video of Ruben Ray Martinez final moments yet.





  • The challenge is that the counterpoint of Boeing culture change causing things like the Starliner is about as valid when regulatory capture happens.

    We’ll its not “regulatory capture” because we’re not talking about regulatory agencies, but you’re right if you’re talking corporate capture.

    I know its going to sound counter-intuitive, but Starliner was actually necessary to break corporate capture.

    The entrenched interests in Aerospace as well as Congress had almost no desire to change. Aerospace loved their “cost plus” infinite money printing machines paid for by government dollars. Contractors had zero concern for cost overruns/ballooning costs. Congress got to land Aerospace jobs in their districts. NASA got working but VERY EXPENSIVE space vehicles every 10-20 years. Fat cats on all sides were very very happy with this arrangement.

    A very small set of politicians concerned about costs (and likely some campaign contributions) along with NASA wanted much cheaper vehicles then they were getting at that time. So they got a proposal to have private companies bid for fixed price contracts for space cargo flights. “UPS for space shipments” essentially. It worked. Law passed It was cheap. It was reliable.

    So then with the success of private cargo, questions were raise why we were spending orders of magnitude more on human flights to the International Space Station? There was much clutching of pearls about these new hotshot private space companies and if they could handle human spaceflight. Somehow Boeing, the trusted legacy maker of the Space Shuttle and Apollo, was convinced to bid on human private spaceflight. There was now a company Congress would be confident would deliver a working solution, and they still got to tell their districts they were bringing pork jobs. Those other untrustworthy “newspace” companies could fail, and Boeing would still deliver human spaceflight as they had for decades.

    We know now how wrong that was, but without that as a possible future, no human private spaceflight would have happened. If it had just been newspace companies like SpaceX and Sierra Space, Congress never would have passed the legislation to allow Commercial Crew to happen.

    So you can see that Starliner needed to exist to break the corporate capture. That had to existed for use to break the corporate capture model that plagued human spaceflight.

    I’m not saying nationalizing companies would help, but a government with good oversight (which is more and more of a question under Trump) could also help.

    I don’t have much faith in that idea. Look at what NASA was before private spaceflight. I love them for other reasons, but look at what ESA (European Space Agency) is today. Safran is a company that is the Boeing to ESA with all the same problems of Boeing for NASA.


  • I’m not NASA or BOEING, but I’m going to imagine that before, Nasa would be calling the shots, essentially designing the craft, and overseeing (as in breathing down their necks) what contractors built.

    You’re exactly right. This, in the industry, is called a “cost plus” contract. What this means is that NASA can ask for whatever they want no matter how outlandish and the aerospace contractor (such as Boeing in for Space Shuttle) will build it for them. NASA is bill for all of the actual costs of the design and construction PLUS a set percentage which is pure profit for the contractor. Aerospace contractors LOVE “cost plus”!

    What frequently happens with big space projects like this is that design objectives change or material limitations are uncovered during construction over the years. NASA may start by saying “we want this to carry 10 Astronauts”. Contractor designs and starts building the main vehicle. Then during a unit test, they find the G forces produced on the angle of the seats is too high for safety, so the angle needs to be changed. All the money spent designing and building the old seats NASA still has to pay, and the contractor still gets their fixed Plus profit. The new design and construction of the safe seats are ALSO paid by NASA as well as a Plus profit for the new seats.

    Now NASA goes “I want a thingy that goes up” and the contractor makes the decisions, cuts the corners it wants, and creates mind boggling cost overruns.

    You’re exactly WRONG on this one.

    Now what was used for private spaceflight companies (SpaceX cargo, Northrop cargo, SpaceX crew, Boeing Crew) is called “fixed price contracts”.

    Ideally, NASA writes out the specs of the vehicle they want to exist. The aerospace contractor looks at the specs, determines how much money they would need to design, build, and profit from the exercise and gives NASA a fixed price. They compete with other contractors bidding on the same work. The Commercial Crew program had 3 bidding contractors, Boeing, SpaceX, and Sierra Space. NASA looks at the general designs, considers the contractors, and makes their choice. This is the end of how theory matches reality.

    In reality, some of the same problems found during construction come up, or NASA changes their mind halfway through the construction. NASA originally wanted the crew vehicles to carry 6 Astronauts. However during landing tests, they found the G forces were higher than they liked on the humans. To lower the G forces, they had to lean the seats back at a less steep angle. However this means that they now can’t fit 6 seats in, but only 4. In a “cost plus” contract this would be business as usually, and the contractor would simply carry on charging NASA more money, but this is supposed to be Fixed Price. But the contractors didn’t sign up for 4 seats in the contract, and they’ve already done a lot of work they won’t be paid for, so contractors reasonably pushed back saying “no we’re not going to work for free. We built what you asked. Now you say you want something different. You want a change, pay us.”. NASA agree, and there were some additional payments made to the contractors.

    So “Fixed Price” isn’t exactly fixed price when NASA changes the specs halfway through. Even with ALL of these challenges, Fixed price SpaceX and Northrop commercial cargo and SpaceX commercial crew have been HUGE cost savings over the old “cost plus” model.

    If you want to see how much, check out the costs of the most recent “cost plus” human space vehicle Lockeheed Orion capsule. Your eyes will pop out of your heat.


  • I’m not sure you understand who makes spacecraft that NASA uses in the past or present. There are not “NASA [built]” spacecraft.

    • Orion is built by a private company Lockheed Martin
    • The Space Shuttle was built by a private company, Rockwell International, which is now Boeing
    • Apollo command module was built by a private company North American Aviation (which was acquired by Rockwell, which is now Boeing)
    • The Lunar Lander was built by a private company Grumman Aerospace Corporation, which today is part of Northrop Grumman.

    The difference between what you’re calling “private company spacecraft” and “NASA [built]” is just contract terms used on how to pay for it.

    You’re also leaving out how (fuck Musk) SpaceX Dragon is also a private company spacecraft and has been wildly successful and saving billions of dollars of tax payer money over running the Space Shuttle in its place.


  • It’s exactly for these kinds of anachronistic things that when I see someone right now agitating to have some kind of age cutoff for people in office, I have a lot of skepticism.

    It’d be ironic for government to put a cap into place for age of 65 (say) and then soon after, humans often start having longer and longer healthspans, extending over 100 and possibly beyond.

    I would certainly entertain an age cap on office holders. What we have right now with almost entirely geriatric leaders is the lack of representation of those not in the senior citizen demographic. Its a version of tyranny of the few. This is exacerbated by the voting power being focused in those that don’t have the suffer the consequences of their choices, and instead leave those for younger generations.

    I’m open to other ideas about how to address this too, but I don’t dismiss an age cap on office holders immediately.

    For that matter, it’d be interesting to see how the Social Security system responds to longer and longer healthspans.

    You don’t have to wonder. We’ve experienced this already in the life of Social Security. The original blueprint wasn’t designed to have a large retired population. You were supposed to die before reaching retirement. Social Security was to support the aging survivors that didn’t die yet to keep them out of abject poverty.

    Retirement age increase is only one of three or four big levers on how to alter how Social Security operates and is maintainable.


  • That’s why 401k’s exist and not pensions

    Honestly, pensions in the USA today are more risky than 401ks. Pensions require the parent company to still be solvent 30-50 years. A number of formerly bellwether companies with heavy pension burdens have gone under an the the pensioners only receive a fraction of the promised benefits.

    Some of the public pensions look very worrisome too. As an example, I have no idea how Detroit is going to manage their pension commitments with its rising costs, declining population, and high number of pension members.

    For all its faults, 401k money is the employee’s the moment its paid with no dependency of the employer to be around afterward.
