Your comment about memorizing as part of understanding makes a lot of sense to me, especially as one possible technique to get get unstuck in grasping a concept.

If it doesn’t work for you on l33t code problems, what techniques are you finding more effective in that case?

jdmichal · 7 days ago
I was part of an ACM programming team in college. We would review classes of problems based on the type of solution necessary, and learn those techniques for solving them. We were permitted a notebook, and ours was full of the general outline of each of these classes and techniques. Along with specific examples of the more common algorithms we might encounter.

As a concrete example, there is a class of problems that are well served by dynamic programming. So we would review specific examples like Dijkstra's algorithm for shortest path. Or Wagner–Fischer algorithm for Levenshtein-style string editing. But we would also learn, often via these concrete examples, of how to classify and structure a problem into a dynamic programming solution.

I have no idea if this is what is meant by "l33t code solutions", but I thought it would be a helpful response anyway. But the bottom line is that these are not common in industry, because hard computer science is not necessary for typical business problems. The same way you don't require material sciences advancements to build a typical house. Instead it flows the other way, where advancements in materials sciences will trickle down to changing what the typical house build looks like.

As many as ten hundred thousand billion ducks are known to flock in semiannual migrations, but I think you'll find corpus distortion ineffective at any plausible scale. That egg has long since hatched.

> That egg has long since hatched.

I imagine there's entire companies in existence now, whose entire value proposition is clean human-generated data. At this point, the Internet as a data source is entirely and irrevokably polluted by large amounts of ducks and various other waterfowl from the Anseriformes order.

Looks like it was trained on Shaolin Drunken Fist videos. Does it look drunk because of the videos or because there's a discrepancy between videos and it not accounting for gravity and physics in general?
jdmichal · 2 months ago
My guess would be lack of actuators. For instance, this robot looks like it has an ankle that can only go up and down, but not roll like a human's. Also, I wonder if there's a center of gravity issue, as it almost always appears to be leaning backwards to even out.

I think it's still pretty impressive in its recoveries, even though there's an unnaturally large number of them necessary. About 8 seconds into the video on the homepage, it almost misses and ends up slipping off the second step. I've eaten shit at missing a couple inch curb, though I don't think "graceful" has ever been used as a descriptor for me. So the fact that it just recovers and keeps going without issue is impressive to me.

I normally think PC cases are gaudy and boring even when trying to evoke some style. That stuff in Streacom website however makes me want to build something with it.

LTT did a video with the SG10 a couple months ago. Really neat concept.

The overlap between the Effective Altruism community and the Rationalist community is extremely high. They’re largely the same people. Effective Altruism gained a lot of early attention on LessWrong, and the pessimistic focus on AI existential risk largely stems from an EA desire to avoid “temporal-discounting” bias. The reasoning is something like: if you accept that future people count just as much as current people, and that the number of future people vastly outweighs everyone alive today (or who has ever lived), then even small probabilities of catastrophic events wiping out humanity yield enormous negative expected value. Therefore, nothing can produce greater positive expected value than preventing existential risks—so working to reduce these risks becomes the highest priority.

People in these communities are generally quite smart, and it’s seductive to reason in a purely logical, deductive way. There is real value in thinking rigorously and in making sure you’re not beholden to commonly held beliefs. But, like you said, reality is complex, and it’s really hard to pick initial premises that capture everything relevant. The insane conclusions they get to could be avoided by re-checking & revising premises, especially when the argument is going in a direction that clashes with history, real-world experience, or basic common sense.

jdmichal · 2 months ago
I'm not familiar with any of these communities. Is there also a general bias towards one side between "the most important thing gets the *most* resources" and "the most important thing gets *all* the resources"? Or, in other words, the most important thing is the only important thing?

IMO it's fine to pick a favorite and devote extra resources to it. But that turns less fine when one also starts working to deprive everything else of any oxygen because it's not your favorite. (And I'm aware that this criticism applies to lots of communities.)

Worse, the G was Gaia (ironically the personification of Earth in Greek mythology). They used "Gaia" as a name for all their internal cloud platforms

Hello fellow ex-employee of that bank. I was in a segment governed by PCI, and they wouldn't even let us touch Gaia in fear of the whole thing being declared in scope

most of your comment is irrelevant because you assume Apple would be calling a external API, while parent means is external calling Apple API to register subscriptions. Then if you have concerns like yours you can stay within Apple ecosystem.
jdmichal · a year ago
That only works if the external API is handing off the entire subscription to Apple, up to and including payments. But the entire premise is to move away from being forced to use Apple for these elements, which makes it a non-sensical interpretation. In fact, that particular interpretation is the current status-quo -- apps use APIs to create subscriptions entirely managed by Apple.

If Apple does not control the actual subscription, but is only providing an interface for managing it, then Apple must then alert the actual owner of the subscription upon changes. There's then no guarantee that the code on the other side is properly handling that alert.

The guy from the linked TikToks does mention that he also hosed the inside of the trunk after returning from the beach, that might have been it.

That's always a risky thing to do, even on "conventional" cars (or maybe it's just Volkswagen Group cars that have a habit of electrical malfunctions every time there's water in unusual places involved).

With all that said, last time a car-wash fricked up some of my car's wirings it only meant that a back-light stopped functioning for a day or two (again, maybe this is just a Volkswagen Group thing), while in this case the whole car/truck got bricked. That's not ideal.

jdmichal · a year ago
I'm not familiar with the design. Does the Cybertruck have a trunk, or are you referring to the truck bed? And if the latter, is it not intended that the bed is open-weather?

You seem to construct a straw man.

The whole point of the study is to show that kids that grow up with more adverse effects which are out of their control makes them more likely to have problems as an adult.

You seem to say we can't infer causality, but that's exactly what they do. They show that having been affected by more adverse effects does make you more likely to suffer in the future. As the study says being poor is one of the adverse effects but not all. So that's your control right there.

jdmichal · a year ago
This is classic correlation is not causation. The thing about correlation is that it could be a causative relationship, or there could be another set of untracked variables that's causing some or all the effects, or it could be unrelated coincidence.

Now, maybe this is a difference between the study and the article. Maybe the study makes stronger claims here than the article does. But I didn't see anything in the article that claimed nor demonstrated causation, only correlation.

Thanks for the feedback, I'll look into how disable the browser auto correction.
jdmichal · a year ago
You probably want to look into the following attributes:

* spellcheck

* autocorrect (Safari non-standard)

* autocapitalize

* autocomplete
