Getting 'Showdown' To 90 FPS In UE4 On Oculus Rift 30

An anonymous reader writes Oculus has repeatedly tapped Epic Games to whip up demos to show off new iterations of Oculus Rift VR headset hardware. The latest demo, built in UE4, is 'Showdown', an action-packed scene of slow motion explosions, bullets, and debris. The challenge? Oculus asked Epic to make it run at 90 FPS to match the 90 Hz refresh rate of the latest Oculus Rift 'Crescent Bay' prototype. At the Oculus Connect conference, two of the developers from the team that created the demo share the tricks and tools they used to hit that target on a single GPU.

How Apple Watch Is Really a Regression In Watchmaking 415

Nerval's Lobster writes Apple design chief Jony Ive has spent the past several weeks talking up how the Apple Watch is an evolution on many of the principles that guided the evolution of timepieces over the past several hundred years. But the need to recharge the device on a nightly basis, now confirmed by Apple CEO Tim Cook, is a throwback to ye olden days, when a lady or gentleman needed to keep winding her or his pocket-watch in order to keep it running. Watch batteries were supposed to bring "winding" to a decisive end, except for that subset of people who insist on carrying around a mechanical timepiece. But with Apple Watch's requirement that the user constantly monitor its energy, what's old is new again. Will millions of people really want to charge and fuss with their watch at least once a day?

Comment Price of commercials (Score 3, Insightful) 85

Eventually, we will all cut the cord and have a choice of viewing modes — on-demand versus scheduled and with and without commercials

Don't expect many people will be willing to pay for skipping the commercials, once they see how much extra it is. You can be certain that skipping commercials will cost you more than $20 extra, are you willing to pay even that?

Why do you think every website, from Facebook to Twitter to the crappy newspaper down the street, is trying to get a way to show video ads? It's because they make a lot of money off those things.

And while we are on the weather; we can actually make more reliable predictions about the climate than about the weather, because weather forecasts try to produce an detailed map of things like temperature, cloud cover, wind and precipitation within very short time frames of a few hours, whereas the detail in climate forecasts is more like averages over decades and across whole regions.

It turns out that's not true, at least right now. Because predicting weather a day or two in advanced is an easily repeatable and testable situation, our models have gotten better and better.

Because it takes a decade or more to test the predictions of a climate model, the improvement cycle takes much longer. It takes a long time to even realize they are wrong.

Water is one of a large class of substances that we would like to find in space for local use, rather than to send back. Any mining materials return operation will want to minimize human presence, but for maintainability that presence cannot be zero. Hence the need for life-maintaining consumables.

The important measure is not what the situation is, but where it's going. The easy surface minerals are gone, and as we dig deeper the minig gets exponentially more expensive at the same time as it runs into increasing environmental restrictions. When we consider how friendly space is to machines, a highly automated asteroidal mining operation could prove cheaper in the long run.

What we need to do next is assay a large sampling of asteroids for mineral content. Why not send out probes equipped with a single high-power laser: fly to a candidate asteroid and keep station near it for a few weeks while zapping as many places as possible with the laser. Spectral analysis of each zap point will tell us the surface composition. Repeat for as many asteroids as we can.

I think that's quite a different issue though. Being the neighborhood tthis kind of h head, I've had quite a few people ask me his to stop the government from spying on them. Even the masses to some extent worry about this. They distrust the government, and for pretty good reason based on how it's been behaving lately. Yet, stuff like passwords on their phones or encryption really only matter if someone has access to their device. People seem to trust others around them, and therefore don't worry about this threat. After all, in the average Joe's mind, a hacker attacks victims remotely, not by borrowing your computer and changing the password of their automatically logged in email, for example.
