  1. Even if the miners are immediately selling their coins, other people are buying them to the tune of (checks market...) 47,551 USD per coin. That's actually down from its peak earlier. It was up to $57k last week, but we will see if it declines further.
  2. Crypto is booming is because people are concerned the dollar is going to crash hard. That is what happened when the bolivar went into freefall: people built mining rigs to convert their bolivars and subsidized electricity into a currency that wasn't going through hyper-inflation. And unlike, say, jewelry, no-one is going to shoot you to steal your Bitcoin cache. You want to fix the GPU shortage, fix the dollar.
  3. Hardware Unboxed did a bunch of drive tests, HDD vs SSD, SARA vs nVME, vs nVME PCIe 3.0 not that long ago: The TLDR is, for gaming, the only big difference is HDD vs SSD. Everything else is past the point of diminishing returns.
  4. How on earth did Transcontinental and Western end up with the B-17 type certificate? I would have thought Boeing would have held onto it like grim death. And given T&W's demise, wouldn't that have migrated it to American Airlines? The P-40's even weirder. Are we talking about Prevost the coach company? With the way the assets divested, I would have thought it ended up with Boeing. This sounds like a subject for an aviation book.
  5. As I recall Fantasy of Flight has a flightworthy P-35, until it got damaged in a hurricane. It did fly in the US, so it would be reasonable to assume it flew with some type of certification from the FAA. I'll see what I can find. Given when the FAA was founded, I suspect you are correct that the pre-P-35 aircraft would not have had type certificates, but I'm wondering if the type certificate might give an indication of any corporations are currently claiming ownership of the P-35 or its lineage. Would probably be worth comparing it with similar certificates for the DC
  6. Well, the contractor itself doesn't exist anymore, and as near as I can tell, no-one else using its likeness or likeness of other aircraft in the series have any attributations to existing contractors at all, so I'm thinking it may have lapsed entirely. Now if you want a shaggy dog story, try and figure out who would likely own the rights to the likeness of the P-40 Warhawk. Would it be A) Curtiss-Wright? B) Boeing Aerospace? C) United Technologies? D) Some other company entirely? Could actually be any of them, or none of them depend
  7. Given that a copyright is a non-physical entity, one generally does have to be able to show some traceablity to the originator when said originator is no longer in existence, before one can assert that one is the new owner. And given the infamous Nintendo vs Universal lawsuit, just because an entity asserts they hold copyright to something does not make it, in fact, true.
  8. Ok. So say they do assert copyright over the material, what evidence should they be able to provide to support their assertion? The material is over 75 years old, and the only association seems to be with the company that bought the company that the original owning company reorganized into.
  9. From what I've seen in benchmarks, the 6800 XT runs better in DCS, is comparable in MSFS2020, but has a major incompatibility in Il-2. By major, I mean the 6800 XT is currently behind the 5700 non-XT in those tests. So, if you are looking at just DCS, a 6800 XT should be good, but if you're a broad spectrum flight simmer the 3080 will be more consistent across the board. This may change as AMD and the various flight sim games release patches and updates. Also, we are expecting the 40 series and 7000 series cards to launch some time next year, so depending
  10. So, was wondering, how does one figure out if an aircraft is still under copyright somewhere? I'd assume if it was from an existing corporation you'd just start there, but how does one check for companies that have been brought out byultiple entities? And how does one check to see if anyone ever retained copyright of the form? As I recall, it needs to be renewed periodically, and will lapse of they don't. Had an idea for a thing that would use some of the old Seversky designs, but I know they've been gone for a long time. I mean Fairchild burned their documentation on
  11. Is that 640 mph at the tip with the aircraft at a standstill? From what I recall, the top speed in motion becomes a combination of the rotation and aircraft velocity. I think I need a whiteboard to draw what I'm thinking the forces are... I'll try that tonight when I'm back at my decktop.
  12. Ah, found it. Thank you. Interestingly, the P-47B, C and D models pre-25 appear to have has a 3050 RPM limit, so not much on a change between the engine versions. I wonder how that interacts with the throttle recommendations for diving? I also wonder what mach speed the tips are at at that RPM? I recall that there was a big drag spike when the prop tips start hitting the transonic region, which leads me to wonder if that could counter the flight speed acceleration on the prop RPM? Have to think about how to analyze and test that.
  13. @grafspee Where were you seeing the 3060 max permissible RPM from? The P-47C/D manuals I've got (AAF Manual no 50-6) list the redline at 2700 rpm, while the P-47N (AAF Manual 51-127-4) only goes up to 2800 RPM. They're pilot training manuals rather than engine vendor specs, so they certainly don't tell the whole story, but I am interested where I could find those numbers. Thank you, Harry Voyager
  14. naca-wr-l-439 Full-Scale Tunnel Investigation fo the Presure Distribution over the Tail fo the P-47B Airplane.pdf@grafspee Found where I'd seen the stall angle referenced: NACA L-439 notes that the P-47B stall angle is just before 17.1 degrees AoA. As I recall most of the contemporaries were in the 20 degree range. Not sure if I have a test report where they actually tested it though.
  15. Haven't been able to find the reference again yet, but the P-47 uses the Seversky S-3 airfoil, not one of the NACA airfoils that nearly every other WWII aircraft used. Severky was a bit of a wild designer and would sometimes just do things. As I recall the S-3 air foil was one of them. I recall it had a very low induced drag, comparable to the later NACA laminar flow wing designs, but only in certain angles of attack. It was weird.
