Comment Capabilities (Score 1) 437

Capability-based security is a step in the right direction: https://en.wikipedia.org/wiki/...

Most programs only need to write in one or two places or modify the exact file you hand them. Permissions and control lists can get exploited, whereas capabilities can't change reference or extend access rights beyond their intended target.

The game Claybook is entirely raytraced

No, it isn't. Here are their GDC 2018 slides: https://www.dropbox.com/s/s9tz...

They are using Unreal Engine 4 for shadow cascades, ambient occlusion, lighting, motion blur, and presumably the background scene. The SDFs are raytraced for first-hit surface intersections, soft shadows, and extra ambient occlusion. The visual giveaway is that there are no reflective surfaces.

Comment "teaching itself" (Score 3, Insightful) 75

> DeepMind learned to beat the best go players in the world by teaching itself through trial and error.

AlphaGo was trained on databases of historical games. It looks for moves that are similar to what a human pro would play, and then reads out sequences to score the strength of the resulting position. It did not learn by itself from scratch. Once proficient, it was played against itself to improve.

Comment possible firefox fix (Score 1) 208

The page you linked loads and performs fine for me, but I had a similar issue recently. My Firefox install is relatively ancient, and it began taking ages to load and then incorrectly render one particular site. What ultimately fixed it was creating a new profile, switching to it to test, and then switching back to my original profile.

Comment persistent default comment threshold (Score 1) 1839

I always want to read freshly opened pages at score 5/4 for full/subject comment thresholds, but if I modify the slider to see more, future pages will open at the last slider setting, not the 5/4 originally set in my preferences. Please prevent the per-page slider form changing the D2 comment threshold option, or add a mode that does this.

Star Trek TNG is science fiction because it explores the social issues of living in a future with FTL space travel, alien life, teleportation, replicators, communicators, tricorders, holograms, AI, androids, insecure computers, and so on. The science in science fiction can be fictional. More notably, Trek content routinely features scientists and engineers as main characters, with exploration and scientific and social progress as core themes.
