  • Using commercial off the shelf technology without proper testing and certification is absolutely cutting corners. See: Kaprun disaster.

    What kind of fire rating did those COTS parts throughout the interior of the vessel have? What kind of redundancy existed? Would you use a Logitech controller for a spacecraft? The requirements of deep sea submersibles and spacecraft are quite similar. Would any of the submersible certification agencies approved this? I think not.

    I see the Logitech controller, the carbon fiber hull, and so many other decisions he made as symptoms of the same corner cutting, “move fast and break things” mentality he had.







  • Lithium ion cells do not have high self discharge rates nor do they suffer from the memory effect. I’ve left 18650s charged for years and they work fine, ditto for 14500 (AA sized lithium ion). Sure, they lose some charge, but there’s still plenty of capacity even after sitting for a long time. Can’t say I’ve ever been disappointed with the various flavors of lithium cells, but NiMH was pretty bad until Eneloops came around. Alkaline is still my go to for remotes.

    You’re also not going to encounter many situations where alkaline (1.5v)/NiMH (1.3v) can be swapped with lithium ion (4.2v). Certain flashlights are the only things I’ve got where you can swap 1.5v and 4.2v and that’s because they’ve got the circuitry to handle that.





  • Antivirus didn’t really exist in my script kiddie days in the very early 00s. It was awesome to put Sub7 on someone’s PC, fire up their webcam, pop the matrix screensaver type hack on, chat to them, then open their CD drive. Freaked some friends out really good that way.

    After they would log off, I’d pull their AIM credentials and hop on their screen name , message one of their buddies, and ask them to “test out this screensaver I just made”. I’d get their IP from the AIM direct connection used to send the file. Rinse and repeat with the next list of AIM contacts. I had a dozen infected people across the country I didn’t know at all. Never did anything particularly malicious but man it was fun.

    Now that I’m thinking about it, I did nuke the HDD of a friend of a friend with a .bat script called hard drive killer pro, that was malicious. That’s the only one I regret doing in retrospect. I just wanted to see if it worked, they didn’t get back online for a year or so.

    Edit: I found the hard drive killer, wow. Munga Bunga’s Hard Drive Killer Pro Version 4.0. I’d love to know how this worked, apparently it could cause physical damage. Not sure how valid that is, but it did completely screw up the PC.
