kahoon··on If I ingest a grain of sand size piece of the Chernobyl Reactor No.4 core
As it is usual when reading Quora "answers".
kahoon··on Ask HN: How to Price a Software Library?
If it's a niche shouldn't you charge way more? $400 sounds really low to me.
kahoon··on Ask HN: One-person SaaS apps that are profitable?
Great idea! How did you market it?
kahoon··on Ask HN: One-person SaaS apps that are profitable?
How does this work? How can you even tell VoIP data from non-VoIP data? I would have guessed that everything is encrypted.

And the TypeScript compiler is now capable of generating the polyfills too, so you don't even need Babel for that: https://bit.ly/2UlW9hs

kahoon··on Memory usage of a toy C# server and client with 500K concurrent connections on
TypeScript supports async/await pretty well (after transpilation of course).
kahoon··on A sane introduction to maximum likelihood estimation and maximum a posteriori
Nice, clear explanation. Looking forward to the Bayesian inference one!

One note though: I think on equation 25 you are missing a log on the left hand side.

kahoon··on Geoffrey Hinton and Demis Hassabis: AGI is nowhere close to being a reality
> I don't think biological precedent is the only or even most valuable heuristic for deciding where to research intelligence...

Good point, we wouldn't have AlphaZero now if we only relied on biological inspiration. Nature hardly ever performs Monte Carlo Tree Search (though I'm not sure this is entirely true, see slime mold searching for food: https://thumbs.gfycat.com/IdealisticThirdCalf-size_restricte...).

kahoon··on Geoffrey Hinton and Demis Hassabis: AGI is nowhere close to being a reality
I don't understand this fixation on symbolic reasoning. Do any other animals practice this? If the answer is no, then it is probably not the most important milestone to AGI or at least not the one we should be currently aiming for. Right now we can not replicate the cognition of a mouse. Feels like we want to go to Mars before figuring out how to build a rocket.
kahoon··on Why Robot Brains Need Symbols
> Please someone who knows much more than me about deep learning tell me how a deep learning ai can explain how it came to an answer.

A mouse can't do that either. Yet we are unable to mimic mouse intelligence with any of our current tools.

Why wouldn't you buy a Ryzen?
kahoon··on Did I just waste 3 years?
> Compare that to the various website side projects I've worked on over the years which have made me hundreds of thousands of dollars (over 10 years).

Was this orders from clients or did you create some SaaS?

kahoon··on Bullshit Jobs
If this was true, wouldn't everybody be programming in assembly? E.g. developing a website in assembly would keep more people occupied than HTML/JS/CSS.

kahoon··on Neural Style Transfer for Musical Melodies
Interestingly though the failures of image generation are often of the missing narrative kind: eg. windowless bedrooms, eyes/ears at wrong places on animals. It feels like that deep learning is good at local but fails at global coherence.
kahoon··on Ask HN: What are fun entertaining YouTube channels/videos you watch in free time?
h3h3Productions became famous by exposing stupid trends on YouTube (e.g. social experiments) but they also cover current events sometimes: https://www.youtube.com/user/h3h3Productions

They also have a podcast: https://www.youtube.com/channel/UCLtREJY21xRfCuEKvdki1Kw

kahoon··on What is backpropagation and what is it doing? [video]
I think this is a very good point. Years ago people were worried about gradient descent getting stuck at a local minima, plausibly because this problem is very obvious in a 3 dimensional space. In higher dimensions however this problem seems to go away more or less and a lot of worrying about the issue seems to be the result of lower dimensional intuitions wrongly extrapolated to higher dimensions.
kahoon··on Q&A: Douglas Hofstadter on why AI is far from intelligent
> And so do chimpanzees. Evolution must have provided us with something additional, which would be our rather more developed cognitive abilities to employ abstract reasoning and metaphor.

Note that the current capabilities of AI systems are nowhere near the general capabilities of a chimpanzee. It seems reasonable to assume that the hard task is to come up with the prior of the mammalian brain. The "easy" part is to discover the parameter space on top of that prior, be it chimpanzee or human.

kahoon··on Artificial intelligence pioneer says we need to start over
You can define 'intelligent life' however you want. No matter how high you set the bar though, an algorithm that reproduces the intelligence of the average human and can be run in parallel at speeds unhinged by biological constraints would provide immense power, wouldn't it?
kahoon··on Ask HN: What books are you currently reading?
I see quite a few people reading this on my commute. How do you find it so far?
kahoon··on Every neuron potentially has a different genome than those it's connected to
> There's clearly a selective advantage for some of those 'configurations', but how many generations would it take for each genetic mutation required to make a lichen katydid or an orchid mantis to converge?

If you pose the question like that with the posteriori knowledge in mind, then yes, these configurations are highly improbable. I think another question that could be asked is: How many generations would it take for some mutations to produce some camouflage effect in some of the millions of existing species? Surely some mutations​ that produce camouflage effects will happen.

kahoon··on Don’t Let Facebook Make You Miserable
Can't you just disable notifications from the Facebook app? Android allows it, and I reckon iOS does too. I found this to be a nice solution to deal with obnoxious apps because you remove the annoyance but can still use them should the need arise.
kahoon··on Saturn moon 'able to support life'
Certainly possible. Dinosaurs were around longer than mammals and their intelligence did not reach human-level. Makes sense if we consider that evolution is a blind process which does not "aim" for creating higher intelligence, and may only happen by chance if it suits the given environment better than other traits.
kahoon··on Carrie Fisher has died
I didn't notice it either. I would also be willing to bet that the majority of people who say his recreation was poorly done only say so because of having prior knowledge about the actor being deceased.
kahoon··on Scientists engineer mice genomes to lengthen their lifespans by 30 percent
If you get longer lifespan wrong you might get the problems you mentioned.

If you get AI wrong you get the end of the world, possibly not just for humans.

kahoon··on Belarus finally bans Tor
I know very little of networking but I assume to perform a TCP reset injection attack, the ISP would need to rely on the IP address of the public onion routers. Now, why do they play around with the reset flag instead of just simply swallowing the packets directed at a tor router?
kahoon··on Tensorflow Implementation of Deep Visual Analogy-Making
> Also, what does "disentangling factors of variation" mean?

Let's say you have a neural network that takes an array of pixels and outputs an array of 10 numbers. This encoding array can be used to reconstruct the image using another neural network.

Now you have a difficult time making sense of what those 10 values represent in your encoding array. By the technique of "disentangling factors of variation" you are able to force your networks to assign specific meaning to a range of indices in your encoding array. I.e.: if you are encoding the image of the car, the first 5 values might represent the body of the car (BMW, Audi, Mercedes have different shapes), and 5 values the rest (pose, lightning, colour).

kahoon··on LSD: My Life-Saving Drug
How did it damage you? Did you continue to think you had a brain hemorrhage even after you became sober or was it "just" very traumatizing while it lasted?
kahoon··on WebGL water scene
I like it. Do you have a YouTube channel or something?
kahoon··on The Fundamental Limits of Knowledge
> So, is there any chance of something OTHER than the heat death or the decay of all matter?

I might have misunderstood the article but I thought the idea is that after the death of matter in this universe the expansion of space will continue. Quantum fluctuations will continue as well and one of them will be the right size that it will be stretched out by the expanding space and a new universe will be born.
