What we’ve learned from the first quarter of the Warriors’ season

first_imgThe Warriors have played 21 games, a little more than a quarter of the way through the 2018-2019 NBA season, and they sit in first place in the Western Conference standings, as was expected.But the way the Warriors have arrived at this point has been anything but expected.Here’s what we learned about the Dubs through the first quarter of the season.1.

Why Evander Kane’s contract could haunt Sharks GM this summer

first_imgDENVER — Evander Kane’s biggest fan in the second half of the 2018-19 season might be the guy sitting in the general manager’s suite at SAP Center.Doug Wilson will be negotiating potential new contracts for Joe Pavelski and Timo Meier this year and you can bet that the seven-year, $49 million deal Kane signed last summer will be mentioned more than a few times by their agents.Kane’s $7 million annual average salary is now the benchmark for contract talks in Sharks territory.The emphasis on …last_img read more

Desert Varnish Growth Can Be Rapid

first_img(Visited 31 times, 1 visits today)FacebookTwitterPinterestSave分享0 New research shows that the black coating on sandstone known as rock varnish or desert varnish can form much more rapidly than previously thought.The abstract of a paper in Geology1 states:Rock varnish is a thin dark coating best known from deserts, and is believed to grow extremely slowly. Varnish samples from near Socorro, New Mexico (United States), contain as much as 3.7% PbO, derived from nearby smelters operating from A.D. 1870 to 1931. Additional varnish, measuring as much as 4 μm beyond the Pb-rich layer, indicates continued growth from 1931 to 2003. Comparison with other varnish confirms that the Pb is not an artifact. Based on Pb layer thickness, and the period of smelter operation, these very young rock varnishes yield growth rates of 28–639 μm/k.y., substantially higher than previously documented fastest rates of 40 μm/k.y. These rates imply that the average 1–2 μm/k.y. rate for older varnish is not the active growth rate. Rather, it is a long-term value including periods of nondeposition, erosion, and active growth. Therefore, models of rock varnish formation should be reevaluated with consideration of much faster maximum growth rates.The new maximum growth rate is nearly 16 times the old estimate.1. Spilde, Melim, Northup and Boston, “Anthropogenic lead as a tracer of rock varnish growth: Implications for rates of formation,” Geology, published online January 4, 2013, doi: 10.1130/G33514.1 v. 41 no. 2 p. 263-266.Interpretive signs about desert varnish appear in national parks throughout desert parks in the United States and probably elsewhere.  How many of them are going to be updated as a result of this revelation?  Probably few.  They will continue to tell unwary visitors that it’s a slow, slow, slow process.  As this paper shows, not necessarily.  Significant buildup could occur in just a few thousand years.  Even so, does any scientist possess the wherewithal and know-how to understand all the variables?  That this paper shows up in 2013 after decades of research on desert varnish should cause perceptive readers to see, once again, that human “scientific knowledge” is limited and subject to change without warning.last_img read more

Using 32-Bit Color in After Effects for Creative Effect

first_imgPretty cool, right? And orange is obviously not the only color you can create with bright-than-white effects. Try out a bunch and see how they can add some cool, unexpected color interactions to your work! Switching to 32-bit mode in After Effects is great for color grading and smoothing out color banding, but it also allows for some cool color effects with “brighter than white” images.I’ve written before about the difference between 8 bit and 32 bit color in After Effects, specifically in color grading. But 32 bit color is great for more than just utilitarian uses like bringing back color information or smoothing out color banding. In 32-bit mode you can actually set colors “brighter than white”, allowing for awesome creative effects.One of my favorite ways to use this is to emulate cool super-white orange colors. First, you set After Effects to use 32-bit mode by option-clicking where it says “8 bit” at the bottom of the project panel. Then add some text. Open up the color picker for the text and set the RGB values to 5, 3, 2:The color will show up as white in the swatch, but as orange on the HSL picker. The way this works is that a value of “1” in every channel makes a solid white. By setting the channels to numbers greater than white, you’re telling After Effects to use a color, but one thats so bright it shows up a white.In the comp window you won’t see much, just some white text. But try this: keyframe a move on the text, and set motion blur to on. You can see the results pretty immediately and it looks pretty cool (note, the “.gif”-ification dulls the colors a little, so definitely try this out on our own to see the full vibrancy):Here’s that same move, but stepping through one frame at a time so you can see what the brighter-than-white color is doing:Now compare this to the exact same move with a glow effect, but in 8-bit mode. There’s really not a good way to balance it. Either the glow is too soft on the motion blur or too heavy on the static text: Here’s the same thing with 8 bit color. Not so good:For one more advanced example of using these settings for cool fire effects, here’s a quick Trapcode Particular particle system I set up to emulate rising embers. This technique utilizes awesome brighter-than-white color and a custom shutter angle on the particles for extra long motion blur:center_img Now let’s compare the 32-bit mode again to 8-bit mode, but with a  a glow. Try adding a blur to the text and bringing it into focus. I used the Camera Lens Blur, but they’ll all do pretty much the same thing to the colors. The result is really cool:Here’s the 8-bit mode with a glow. You just don’t get that complex blend at the bright white center:That uses a lot of blur, but what about just a little? Let’s make this text smolder.I’ve added a Rough Edges effect, set the Evolution to move with an expression (time150) and keyframed the Offset (Turbulence) to move upward. Now, the Roughen Edges effect isn’t a 32 bit effect, so it makes the color 1, 1, 1 (plain white). To fix this, you can add a fill effect to the text and reapply the 5, 3, 2 color values after the Roughen Edges effect. Add a light blur (maybe a radius of 6 or so) and you get a pretty cool smoldering text effect:last_img read more
