I think the reason you see things like Blizzard killing off Overwatch 1 is because the Lindy effect applies in gaming as well. Some things are so sticky and preferred that you have to commit atrocities to remove them from use. From a supply/demand perspective, if all of your customers are still getting high on the 5 (or 20) year old supply, launching a new title in the same space isn't going to work. There are not an…

I purchased "approximately $0.00" in TF2 loot boxes. How much exactly? Left as an exercise to the reader.

I am a volunteer firefighter and hold a degree in electrical engineering. The shenanigans with their shunt resistors, and ensuing melting cables, is in my view criminal. Any engineer worth their salt would recognize pushing 600W through a bunch of small cables with no contingency if some of them have failed is just asking for trouble. These assholes are going to set someone's house on fire. I hope they get hit with a…

Has anyone made 12VHPWR cables that replace the 12 little wires with 2 large gauge wires yet? That would prevent the wires from becoming unbalanced, which should preempt the melting connector problem. As a bonus, if the gauge is large enough, the cable would actually cool the connectors, although that should not be necessary since the failure appears to be caused by overloaded wires dumping heat into the connector as…

I don’t want to jump on nvidia but I found it super weird when they clearly remote controlled a Disney bot onto the stage and claimed it was all using real time AI which was clearly impossible due to no latency and weirdly the bot verifying correct stage position in relation to the presenter. It was obviously the Disney bot just being controlled by someone off stage. I found it super alarming because why would they f…

Might help a little bit, by heatsinking the contacts better, but the problem is the contact resistance, not the wire resistance. The connector itself dangerously heats up. Or at least I think so? Was that a different 12VHPWR scandal?

Contact resistance is a problem. Another problem is when the connector is angled, several of the pins may not make contact, shoving all the power through as few as one wire. A common bus would help this but the contact resistance in this case is still bad.
