  • Sure the parts I needed weren’t available. Which is probably the problem with these iFixit scores. They should really wait for the laptop to be a few years old and then look and see if the stuff that’s actually breaking on the laptop are actually repairable with the parts available.

    For this particular laptop even though it had a really good iFixit score, I couldn’t even buy a new touchpoint nub (or whatever HP calls it). The old one completely disintegrated but the nub was different than other HP laptops, so the ones I tried to buy (even for other elitebooks) wouldn’t fit. The nub the laptop needed simply wasn’t available anywhere.




  • Bradley is surprisingly good considering all the “Pentagon Wars” development hell. I think a lot of people still think its junk. When it was more effective than the Abrams in Iraq the theory was that the fighting there mostly didn’t require tanks. In Ukraine of course, the fighting was very mechanized in the beginning until equipment losses and drones ended it.

    And the Bradley still did very well, better than the MBTs. At this point I think it’s reasonable to wonder if MBTs are obsolete, if not all tanks. A lightly-armored vehicle like a Bradley is going to be no more vulnerable against modern MANPATS and drones than a MBT, but it’s going to provide just as effective protection against small arms. It’s easier to maintain, longer range, and it can do more missions.






  • “It’s at 90 PSI and is 80 percent air, 15 percent water, and 5 percent oil,”

    Something’s seriously wrong with the air system then, and it will contaminate all their work and compromise the welds. Water is a particularly pernicious contaminant in welding because it causes hydrogen in the weld that will make it brittle and crack.

    Welding shops have to be CLEAN. There are some welding processes that can work ok with dirty metal (SMAW with some electrode types) but these only work on mild steel, and these processes really aren’t used in a shop or production setup, more for field work.
