Ferrari has officially unveiled its first-ever all-electric car, the Ferrari Luce. Deliveries begin Q2 2027. • Starting price: $640,000 • 1,050 HP, 0-60 mph in 2.4s • Four electric motors with 800V architecture • 122 kWh battery, 280-mile EPA-est. range • 350kW peak charging speed • Four-door, four-seater design • OLED screens + 5-level paddle shifter torque control • Simulated “musical” motor sounds inside & outside the car

Ferrari has just officially unveiled its first ever all-electric car, called the Ferrari Luce. • Starting price: $640,000 • Interior co-designed with Apple's former head of design, Jony Ive • Range: 280 miles (expected EPA) • Peak charging speed: 350kW • 122 kWh battery • 1,050 horsepower • 0-60mph: 2.4s • 800v • Four-door four-seater • Four electric motors • OLED screens • Weight: 4,982 lbs • Front motors spin to 30,000 rpm, rears hit 25,500 rpm • Car uses an accelerometer to capture real vibrations from the electric motors & rear chassis. An algorithm filters out unpleasant frequencies and amplifies only the more “musical” sounds. This can be heard inside and outside the car. • Paddle shifter on steering wheel changes how aggressively torque is delivered, with five different levels • The trunk has 21.1 cubic feet of space, the largest luggage capacity the company has ever offered • 197.6 inches long, about as long as a Tesla Model S U.S. deliveries start in Q2 2027.

数学不好的我，卡了…救命呀 stitch真的很好玩，但有点遗憾的地方是只能在switch玩。老版本的switch不是oled版本，百天玩阳光下屏幕有时会看不清楚。用平板个人觉得会更爽一点。这个游戏也有部分优化做的不行，有时候会出现花屏然后自动退出游戏模式…解不出来只能打王者荣耀了，听说又要新赛季了。

南区でのイベント、お次はこちら💁‍♀️ 今年も #笹川邸# でお着物が着られるなんて 幸せだわ😌 栗田呉服店さんで 着物レンタル4000円は安いなぁ😍 ぜひこの機会に お着物はいかが？？

Watching the space scenes in the Martian on an OLED TV should be an ideal viewing experience with the true black backgrounds, but in every shot that panned, I couldn’t stop fixating on the incorrect twinkling of all the stars. This is almost always caused by something linearly interpolating pixels that are in a gamma encoded color space. The 0-255 pixel values that you find everywhere aren’t linear — 64 is not twice the photons of 32. It is close enough that you usually won’t notice, but high contrast star fields and line drawings are the worst case. There are so many places this can go wrong. I assume the movie master is rendered correctly, but any resampling to a different resolution will probably do it wrong. I was watching in 4K, but 3840x2160 is not the native theatrical resolution. There is an @FFmpeg option to do gamma correct resizing, but it isn’t the default because it is quite a bit slower. Lossy compression can also mess up the subtle fractional pixel values, but star fields should not be challenging to compress. A fixed bit rate should be nearly lossless in “easy” scenes like that, but an adaptive one can drop it to a trickle and make the errors perceptible. A 4K video decoded to a 4K buffer sent to a 4K TV should not involve any resampling, but it is easy for a half pixel offset to slip in somewhere, and GPUs don’t offer a gamma correct YUV textures sampling mode. If you need resampling (as in a VR screen) the best practice is to copy the YUV video to an sRGB texture, then draw that. Any color space transform for the various “vivid” / “cinematic” / whatever modes that gets done in the media device or TV also have to be done in linear space to avoid issues. I tend to rail against these abuses of the pixels, but if you must do it, at least do it right. The same with any motion interpolation or other features on the TV. At the very end, the display panel must actually accurately reproduce the gamma curve everything else in the pipeline expected. There are legitimate subtleties here, like 2.2 vs sRGB, but sometimes things are deliberately distorted to “punch up” unknowing content. So many problems vanish if you just work in 12+ bit linear space, but so far, it has generally been better on net to spend memory/GPU/display bandwidth on higher resolution or frame rates. It is creeping in, but it will be many years yet before end to end linear is common.
