I'm gonna take a stab at assessing the relevance of the mistakes to a self-bootstrapper: 1. Single Founder: Plenty examples of successful bootstrappers on Indiehackers. There are also plenty of failed bootstrappers, but you likely won&

This might sound crazy, but is there such a thing as programmable terrain? I can see this being technically feasible and adding realism to a VR game, but it might be cost prohibitive or a liability when people fall. It'd be cool tho if

I've heard often about how the energy estimate for warp drive has been revised down from the mass of the universe to that of Jupiter. Forgive my ignorance, but is this just a matter of refining the shape of the warp around a spaceship,

I think proquints [0] are pretty good at encoding for humans as well. For example, when used to encode IP addresses, they result in pronouncible identifiers like this: 127.0.0.1 lusab-babad 63.84.220.193 gutih-tugad 63.118.7

My suspicion is with the low hanging fruits gone, investors will soon turn their eyes away from growth-at-all-cost unicorn potentials to profitable companies that target tiny specific niches.

I wonder what if we decide that 'fate sharing' is OK, i.e the client request flow (not the entire process) fails when a network step fails. How long can a system stay operational after it started before the whole thing grinds to a

We speak in hypotheticals of course, but barring any physics defying barriers here, one can imagine a future where those issues you raised have been addressed (e.g improved simulation/ML techniques, less red tape, faster trials, greate

I'm not an expert in ML/Biology, but I wonder if doing so won't completely eliminate all of humankind's diseases, but shift the battle from one between humans and bacteria/viruses, to one where ML takes the place of

I maintain a blog that teaches readers how to implement toy versions of big projects in C++ at https://littlebigprojects.io . I hope to eventually cover distributed systems and compilers.

And I'd say that ethical decision should never be moved up the chain. War is ugly, and should be ugly so that we think twice before waging one. You can still keep a level head with non-autonomous systems, e.g drones with human operator

Excited in the way that the big robots we read so much about in stories become real, but I don't wish for the world in which those death machines become a necessity turn into reality.

I'll grant you that there weren't much ethical considerations to speak of in the last world wars, and perhaps my naive view has been unrealistically colored by sci-fi TV shows, but my point is simple: a broken autonomous killing s

On one hand, I'm pretty excited that something from the universe of Ghost in the Shell would become reality; on the other hand, it's a slippery slope to some dystopian reality where ethical considerations are completely removed fr

This immediately brings to my mind workflowy. You can insert new bullets under existing bullets, and link bullets using hashtags. If you expand the bullets, then it'd look like you have linearized them.

Can we apply the steps to reading source code? Here's my take on adopting it to reading code: 1. Read readme if available, read the list of source files to get a sense of how the project is modularized. Identify the entry point. Identi

Because language choice is more than just about whether it's the fastest for your specific concern at the moment; it may be slow or non-ideal in other situations. C++ in general is pretty fast. I may be biased since I used to write C&#

It doesn't have to be fastest, it just has to be faster than what you're using now. C++ compiler has a suite of automatic compiler optimizations that'll make your code performant. Things like loop unrolling, strength reductio

It's in my experience that when one elects to keep themselves busy with A instead of B, it's because they're more adept at A than at B. Doing B requires one to get out of their comfort zone, and doing A let's them believ

What about img? It's not inconceivable that an article or a reference manual should have images of some kind.
