  1. One of my lecturers had the livestream of the launch sharing half the projector space with his presentation, it would have been cool if they lifted when I was watching live
  2. Historical balance is the least of WoWP's issues
  3. The rocket goes hypersonic backwards? She says they're only for re-entry at 1:30
  4. It looks like here has "show all" set as default. Of course, no way of knowing for sure until february On TN, at the top of each board there's a bar with buttons for "recently updated", "start date", etc - different ways to filter the threads. right hand side of the row of buttons is called "custom", you can set the desired cutoff date in that
  5. Evidence of habitation is useful for territorial claims. Same reason china is making islands
  6. The forum settings default to "only show threads from the last 3 months", could that be it?
  7. Apparently duplet can stop BM-42 - video was found on tanknet in a post by Damian
  8. So pretty soon we'll have enough grunt to just emulate them in software, meaning any games exclusive to a given console are now shared with PC?
  9. All modern chips have heat activated kill-switches - for a modern PC it's advanced enough to reduce the frequency and power consumption first in the hope it'll cool down if it gets too hot. Intel designed that cooler to manage that chip just fine in a sealed case, and since turbo boost is pushing it to 4.3GHz then the chip must be completely happy with the temperature.
  10. Erm, I think you made a mistake in that calculation - 60000 psi over that radius comes out around 300N, not 3N http://www.wolframalpha.com/input/?i=60000psi+*+%281mm%2F2%29^2+*+pi That's pretty significant for such a thin sheet of brass. You do have a good point about the bolt keeping the rest of it in - I'd forgotten it was so close around the firing pin. As for the pressure release, it sounds odd to me - the path from the propellant to the primer is quite open, so you ought to end up with a substantial amount of gas blowing past the primer if it is going to equalise the pressure. Also, with that gas cancelling out the chamber pressure, you shouldn't expect to see machining marks on the primer surface
  11. Or more specifically, why don't they burst? You have huge pressures behind them, they're thin and not really solidly fixed in place, and yet they are expected to stay intact - how? Me and colli were discussing this on TS yesterday, and there's no way inertia of the firing pin could be providing meaningful support - from squinting at a pressure Vs time graph of a 30.06, and assuming the firing pin can be modelled as a piston of radius ~1mm acted on by the chamber pressure, the applied impulse is on the order of kgms-1. So that firing in should be moving backwards at a considerable velocity, given the light weight, and over the ~1millisecond of the firing process it should move several mm back - yet primers retain the impression of the firing pin after firing. The peak force applied was on the order of kN, so I'd be very surprised if the firing pin spring was providing enough of a force to resist this
  12. The soviets were scared in general of ATGM's - look at the gulf between M41 and M551, or between AMX 13/75 (which had ATGM's fitted at that time to improve the firepower) and 13/90
  13. The manual for the mobo should tell you how to set the xmp profile (eXtreeeme Memory Profile!), which would sort that. You'd think someone would have figured out how to do that as standard by now
  14. Computers are fairly easy to build, even I managed it
  15. Now you've mentioned it, you've got to post it
  16. On-board video is fine, I used it while waiting for a dvi cable to arrive with no issues
  17. IIRC sturgeon mentioned once that the british 4.85 had the same muzzle velocity as the 5.56 of the time, since it had less of the swept volume goodness
  18. Windows 8 with classic shell or similar is nice, as long as you avoid the apps
