They are actually pretty simple. Essentially you generate the Dijkstra values for an undirected graph (this can be a grid, navmesh, etc), then you create directed edges pointing from high values to low values. So a grid space of value 8 wil

I am not sure why you are being downvoted. I have been doing a project with Homogeneous Transform Matrices recently and also assumed that this was "obvious" since the shear diagonal lives in the rotation part of the matrix. Still,

> I read that it took 16,000 88 flak shells to bring down one bomber. I infer the success of the flak was due simply to quantity. I am not trying to be pedantic, just wondering out loud. 16,000 shells per bomber sounds like a lot, but I

Sorry I worded my previous response poorly. > The 8.8cm german flak gun WAS a radar-guided AA gun. The Kommandogerat 40 was a rangefinder/computer, not a radar. It had the capability of being radar-guided, but was not necessarily ra

My weight fluctuates pretty normally depending on my exercise level. When I'm actively lifting weights I am in a calorie surplus and usually end up a bit overweight. Losing weight is fairly easy. You just count calories, avoid sugars,

What does fgemm signify? Why did you set up a redirect to your own HN comments? Memory preservation?

That's a good point, I decided to do some napkin math: Sanibel Island has 7,821 housing units at an average density of 454.6 per square mile. Median sales price of the homes in 2021 was $1.64M, average price was similar. So a rough app

Build up my savings to the point where I can live comfortably for 2+ years without a paycheck, or 4+ on a tight budget. DCA into ETFs with the leftovers. Buy a little bit more non-perishable food than I need every time I go to the store. Ex

Human brains are funny. Obviously the absurd part of all of this is people (literally) building their houses on the edge of the ocean and expecting this to not happen. However because it's all we know, it seems that the real absurdity

I always interpreted this work as a satire of Ayn Randian style objectivism/exceptionalism. It's funny that in school we were taught that it was a criticism of communism/socialism when I think it's really a criticism of

Yep. I am a junior engineer. I got a message on Linkedin, someone was offering me like $2k/week to take interviews/technical assessments for clients overseas. I asked if it was legal and he stopped messaging me.

I always wondered how their initial python web scraper was fast enough to index the entire internet on that old hardware, even given the small size of the internet at the time. I guess the answer is that they had a local backup at Stanford.

Politics and war aside, I think it's cool that the profile of the B-2/B-21 airframe closely resembles a falcon in a dive. The control scheme of the falcon is similar too. I wonder how much of it is a coincidence and how much is a

That's a fair assessment. I don't think I have enough information to determine either way.

For anyone who thinks that Snowden is just a puppet of Russia, or that the CIA needs to walk a gray line to defend the US interests in the name of some global greater good: Do you think those chickens will never come home to roost? Do you t

I read it more as him trying to point out an incongruence between American political discourse and the realities of American realpolitik. On the one hand you have Biden calling out Trumpism/MAGAism as a threat to democracy, on the othe

I think corporate taxation is the only way out of this mess. Tax the profits, take money out of the system. It makes extra sense given that most of this money was injected into the system in 2020 anyways. It's not like it was 'ear

I was making the underlying assumption that wealth has some correlation with intelligence (for someone who made money in tech at least) Tech bros need money to get height gainz -> must pass tech interviews/bring a product to market

How would they know? Are you divulging the fact that your height is the result of a procedure on the first date? Also are we assuming that women prefer tall men because they want tall children, not because tallness is just an attractive tra

I kind of sought to answer this for myself in a roundabout way. My first experience with web dev was React. I never learned "why" so on a recent personal project I figured I'd start from the ground-up. First I wrote a little

I see value in it too. Russia was a safe haven for US leftists and civil rights advocates during the 20th century. But they see no actual value in the speech they are protecting outside of 'trolling the US' for lack of a better te

Yes, if a left wing agitator is rallying their followers to violence, they should face some sort of consequences, and they often have throughout the 20th century. It's not hard to find examples of American three-letter agencies targeti

It's not about partisanry, it's about people facing consequences for doing bad things. Why are you ascribing partisanship? You can hold right-wing values and not harass trans people. Conversely you can be a left-wing terrorist. Yo
