Another notable, if old, train simulator from Japan is OpenBVE. It was easy to model railroads on it. Many short Brazilian routes were/are modeled in OpenBVE. It is particularly convincing since it simulates well the typical lateral wobbling that metric trains are known for.

Having a single big DC converter at a home would help a lot with power factor (LED lamps connected directly to AC have terrible power factor).

Re:WhatsApp became an unstoppable cultural force
on Saturday December 14, 2024 @03:56PM (#42419382)
At least here in Brazil, WhatsApp consolidated its position by working well in feature phones that ran J2ME and dominated the low-end market before Android. It took testing and adaptation to each and every available phone (as far as I can remember, J2ME was kind of a loose standard so developing a J2ME on one device did not guarantee it ran well, or at all, in any other). This, coupled with the possibility of eliding the outrageous SMS rates and the availability of EDGE data plans.

Re:There's No Good Reason to Buy a Carbon Bike

Partly on my own experiences, used to have a steel bike w/o suspension that I rode for thousands km and it was a joy, the next bikes I've had were aluminum and locking the suspension makes them unbearable. But yes, could be the geometry as well.

Re:There's No Good Reason to Buy a Carbon Bike

Some say carbon fiber has the steel-like dampening properties. And steel can be welded by anyone. OTOH an aluminum bike has to have suspension because it is so harsh to ride w/o it.
In general, the whole current bike culture with very expensive bikes/parts and a plethora of expensive and semi-proprietary tools is disgusting.

It would be great to have 48VDC in homes, for lightning, light appliances, etc. to centralize the whole power factor control in a single big power supply instead of doing it (poorly, or not at all) at every LED bulb.
