In the PinkBike video, they mentioned that the full-face helmets didn’t perform as well in at least the rotational impact tests due to their higher mass and moment of angular momentum.
I think it always ends up being a bit of a trade-off, depending on the types of riding and impacts expected. In a low-speed impact to the side of the head a regular bicycle helmet will often do better than a big heavy motorcycle one. Obviously the opposite is true for a motorcycle crash at 80 km/h.
Run energy changes sound like a good idea. IIRC this is already similar to how RS3 does it; Iwonder when it changed there. Though weight feels like it has no impact in RS3, so that’s probably a good way to balance it.
I’m not sure I see this one to be honest. As bad as a car-dense city is for everything else, it’s probably the best option if the whole city had to be evacuated.
A large portion of alternate transport is focused within the city (trams, bikes, subways, etc). I suppose at least busses could be re-purposed for evacuation, but it requires a whole lot more organization.
Furor might be too, sibling.
Lol
I mean there will still need to be spring-loaded pins somewhere in order to make good connection. And tiny pins means someone will bend them by accident at some point. And the pins are still a little involved to make, so taking them off means the RAM can be made cheaper. So this means:
- if just replacing/upgrading RAM, then no need for extra pins to be made
- if adding ram to a slot that didn’t have any before, then can also buy pins or they can come in some kits or whatever
- when someone bends pins, then just the pins can be bought for a reasonable price, instead of replacing expensive RAM, or very expensive motherboard
That was one of the things that excited me most from the iFixit video; the (LGA?) pins are a separate part that can be replaced as well. Simplifies the motherboard because then there are just flat pads on there, which means they don't need to include the whole array of fancy pins for a second module if it doesn't ship with one.

I think this is the correct link for the SpaceX official feed on X/Twitter: https://twitter.com/i/broadcasts/1LyxBnOvzvOxN
Looks like it's scheduled to start at 6:56 CDT now that launch is targeting 7:30 AM CDT.
Looks like some sort of fuelling is underway. Or at least chilling lines in the OLM and tower in preparation for filling.
