In terms of low-level safety, they can probably back out forces on the robot from current or torque measurement and detect collisions. The challenge comes with faster motions carrying lots of inertia and behavioral safety (e.g. don't pour oil on the stove)

It’s human nature to make inferences about the world - to observe effect and infer cause. No matter whether the cause you land upon is Jupiter sending a storm to kill the crops, or global weather patterns, you’re still using data to make guesses about how the world works. “Science” (capital s) isn’t limited to discovering oil or landing men on the Moon, it’s also about feeding your family, or guessing what the best birthday present for your kid is. It’s an inextricable part of us.

FWIW I thought it was a really good overview of the project structure and I appreciated the lessons learned as well.

silentwanderer — Wed, 19 Oct 2022 04:03:35 +0000

It's not just you. I'm in my early 20's and I've noticed typing has gotten considerably worse over time. Me and my friends used to be able to text each other without looking at our phones while holding a conversation, but now it's a lot harder. I've had to rely on slide-to-type more and more instead.

Pixel density high enough for acceptable text is already possible, just prohibitively expensive. See Varjo's headsets, for example - at the center of the display they have 70 pixels-per-degree (for comparison the Quest 2 has about 20).

The free version of Grammarly is a spelling/grammar checker, while Hemingway seems to enforce a particular style of writing.

I may be mistaken but I believe this method of computation is referenced in Harry Potter and the Methods of Rationality

The only sticking point for me is that Nvidia has features like DLSS that could extend the longevity of my card

As an 18 year old, I’ve learned so much in the past few years about developing good software it’s mind-boggling. I can’t imagine what 10, 15, 20 years of experience would look like.

silentwanderer — Wed, 10 Jun 2020 20:59:41 +0000

I definitely agree that large single screens are better in some cases, but not everyone can afford a 27” 4K monitor. I can however, afford the 1080p monitor I found at the thrift store. Most of the time I use my second screen for documentation, anyways - I don’t have to interact with it heavily.

Microsoft's recent announced open-source Fluid framework sounds very similar to this - I wonder if that played into their decision to make this free.

New comment by silentwanderer in "What is a control system anyway?"

silentwanderer — Mon, 18 May 2020 18:14:57 +0000

In high school we nearly always left out the I term because we didn't mathematically verify our controllers, couldn't risk breaking the systems we were controlling with windup, and cared more about smooth and predictable motion than accuracy.

New comment by silentwanderer in "Why are Soviet math textbooks so hardcore in comparison to US textbooks? (2017)"

silentwanderer — Wed, 22 Apr 2020 04:29:42 +0000

I think the point is that Russia's programs isolated those who had a talent/passion for math as opposed to just trying to bring every student to a basic level of understanding. If a student doesn't have the drive/talent/passion for a field, it follows that they will not perform as well in the workforce as their driven/talented/enthusiastic peers.

Mathematics and problem solving are not mutually exclusive - understanding one is usually a sign you understand the other. Programming is just a layer of abstraction over one of these things.

I think the main value of CLUI is that it flattens the learning curve for users who don't normally use the terminal, not that it scales all the way from new users to experienced ones.

If you look closely, you'll notice that the stopped cars aren't actually blinking - their outlines are changing color from yellow to black. Who knows what that means, but at least it isn't losing track of cars completely.
