A friend of mine works on simulating mouse organs. We had some pretty great talks over beer about modeling and cross model validation. Eventually he'd rant about all models are wrong but some models are useful.

If I remember correctly, they had some success in rejecting animal studies. Things like, we don't know what this will do overall, but we're pretty sure the kidneys or liver will fail like X, so don't bother with the wet lab. Or possibly try the wet lab at small scale so they can validate the model.

We're far far away from full simulation. But we know a whole lot about mice. I internalized those conversations as, my friend writes type checkers for drugs against mouse hardware.

This completely bypasses the revolution that will take place long before this: Organs on a chip. With the development of organoids [0] we made the first step. Things like the lung-on-a-chip [1] are steps towards a sort of mini body that mimics many functions and simulates the body not only in the molecular biological way but in the very important physical way (which, it turns out can not be decoupled from the molecular biology).

Why would we put mice in computer chips if we can have pseudo human bodies in the real world?

This drag & drop behaviour is still perfectly viable in WinForms eg. using C#.

Modern fortran is surpisingly pleasant to write.

The last time optimisation came up, I tried the author's problem - multiplying two 4096x4096 matrices - in numpy, FORTRAN and Rust, on a standard laptop. Supposedly it took 9 hours in naive Python (I didn't try). Results were:

Python3 (numpy 1.18.4) 1.3s
FORTRAN (gfortran 9.3.0) 6.0s
Rust (1.43.1, debug) >60s
Rust (1.43.1, release) 4.0s

What surprised me is that python and fortran solutions were written in minutes. The Rust solution took hours and multiple forum posts for help. There's no obvious way, and every single way I tried had "gotchas" and utterly astonishing behaviour in it, particularly with simple, statically-allocated arrays.

Fortran could do with proper namespaces, and properly dropping some of its older conventions, though. Reading it feels like archaeology.
I sent you something a few days ago. I think I'd be a particularly good match and I'm pretty passionate about search. (For instance, as I type this I'm about a week into a distributed task of OCRing 650GB of scans of old scientific literature so I can do some fuzzy matching on it and build a cross-referencing system for some project I'm working on - this is purely out of personal interest and running in my living room). I do things like this because I find the existing search tools to achieve what I'd like to be inadequate.

Also as I write this I'm listening to a music crawler I've built that tries to navigate and cross-reference through currently 260 music labels and about 12,000 releases in order for me to find new music (using discogs, bandcamp, etc). This is just running on my laptop. Again, I've found the current music discovery systems inadequate to my desires so I built my own.

I don't know how to stand out from the pile. My username on here is part of the email I gave you. Hopefully if you can find what I wrote you'll agree. I hope to hear from you soon.
Model: the learnt relationship (eg., f(x; a,b) = ax + b)

Parameter: an aspect of the model, a dial which is fixed by data (eg., a)

Kernel (as used here): a subset of such parameters

Algorithm: procedure which accepts data and produces a model

Hyperparameter: an aspect of the algorithm, a dial which changes model production

Convolution: A convolution of image A and Filter B describes to what degree A is "like" B. Here "Filter B" is a kernel, ie., a parameter set learnt by the network.

The goal of a CNN is to produce a model whose parameters are image filters that describe the degree to which an images expresses various shapes. By learning the filters from an image set, the network is specialized to distinguish images in that set.

Ask HN: Which service to use to show web-site design mockup to a client?
Hello. I'm doing WordPress development on the side, and usually clients provide their designs for web-pages themselves. However, new client wants me to come up with the web-page design. I'm curious, what is the go-to service these days where one can mock up a web-pages with dummy data, preferably link them together, with ability to toggle mobile version? Maybe, Figma? My goal is to show client a mockup-page where they can approve the design, and I then will focus on recreating this design in WordPress.

Relativity behind mercury's liquidity (2013)
Realistically this unlikely to be a problem in this century, however you are raising some valid points nonetheless. A lot of,if not most,capabilities animals, including humans, have are related to one thing: survival. Ability to move rocks, climb trees,or build sophisticated structures boils down to body's need to get food and preserve itself from destruction. These aspects are often overlooked when modelling AI and the whole focus is on pure logic. I sometimes think that one day we'll end up with universal AI and the first thing it will ask will be sometime like: "why should I do it?".

Moderation by the people for the people is exactly what we have now. You think Medium or Facebook want to put so much effort into moderation? Their moderation is merely a reflection of what most people want, and when it strays, they are punished and shamed by the masses. Journalists, advertisers, and users start yelling at you for allowing [insert unpopular group here] to mingle with the rest of them.

Ironically you'd likely need a more dictatorial platform to avoid censorship. You'd need a strong dictator to resist the censorship demands of the people. What we have now is a tyranny of the majority.

Electron is hated on Hacker News. I personally critique it quite a bit.

But here are a list of things that Electron does better than any other desktop GUI framework.

1. Skills portability. Just use HTML and CSS to build your layouts. Hundreds nee thousands of web developers become instantly desktop developers, at least when it comes to UI development

2. Non natively cross platform. Your app looks exactly as you designed it across all major platforms. Down to the last branding design element. Without any additional effort.

3. Vast CSS, Node and JavaScript library ecosystem.

4. Flexibility in UI. I have yet to see a traditional UI library have the flexibility of CSS + markup.

5. Good enough native integrations. Users don't lack any of the major native integrations.

I am sure there are downsides of Electron. But unless a pure native library challenges some of the pros of electron, it will continue to grow in popularity.

People no longer give them the benefit of that doubt because of the reputational damage these previous violations have caused.

They should stop making "innocent" mistakes with other people's privacy and deal with this more professionally at the highest levels.

If they don't people will continue to jump to the conclusion that this sort of activity resembles criminal behaviour.

I know very little about CNNs. But, I noticed the ReLu Activation step is Max(0,x) where x is the sum of the pixel intensities from each channel. In this example, it appears x > 0 (for all x) and so the activation step isn't really doing much?

EDIT: I'm wrong. x < 0 for some of the pixels. Specifically for the more red-ish channels.
I actively follow the state of the art pre trained models on paperswithcode.com and Nlp progress.
The state of the art (often outperforming BERT by far) is XLnet and sadly is from 2019.
2020 has been stagnating (except for the special case of generative tasks with GPT3)
I have observed that zero researchers have tried to improve on top of XLnet.
While BERT has had ~20 alternatives implementations that improve upon it.
Researchers are often unaware of what is the current state of the art,this induce a lag in research progress.

This looks great. I have previously written a small GUI application with Qt where it's just a slider and a text label, and when the value of the slider is changed, a command is ran and the label updated.

Just a shout-out to Professor Polo (the Professor who is the leader of the Polo Club of Data Science who wrote the tutorial on CNN's), 3 years ago, as a CRUD code monkey, I found out about Georgia Tech's launching of Online Masters in Data Science on Hacker News and then entered into the program and took Dr.Polo's class on Data Visualization and Analysis (for that semester I lit. spent more time on the class than on my day-job)... now for going full circle 3 years later, I see Dr.Polo's tutorial on CNN on Hacker News again and am working on CNN/RNN's for my last class/capstone project lol.

It isn't a particularly reasonable criticism of honest intellectuals on the left.

It's a completely accurate depiction of low-brow populist left-wing extremists, because they disregard the nuance of their own side's positions and just do the thing in the picture, and then use the conclusion to rationalize vicious hostility and censorship.

> commits and corrections are submitted to alter the books

I think this is good idea fro books, and I wish more scholars would contribute to Wikipedia and other peer editable overviews.

I'm not sure quite how it would work for new results though, for which it is still not quite clear how they fit into the current knowledge, or if they are worthwhile at all.

People also tend to feel really strongly about their own original ideas, and may try to push them forward when they should rather be forgotten.

I don't know how to prevent something like that, other than having a BDFL or individual publishing (as in the current system)
I hope at least 20-30% of the people involved in the project are at least near-native level speakers of non-Indo-European languages. Linguistic biases based on your mother tongue die hard, and I know this from having waded through tons and tons of software designed with biases built-in that woefully disregard Asian syntax, typography, input, grammar, semantics, etc etc etc. As the whole point of the project is multilingual support, I really hope the developers don’t underestimate how grammatically and semantically distant different language families can be.

Not a low-level one but the CLR natively supports multidimensional arrays although I don't think they are exposed to C#.

I've written some F# code and for some trivial cases I was benchmarking there was some interesting performance differences between a native multi-dimensional array and an array-of-arrays version.

It wasn't important enough to look into so I don't know if the difference is due to quirks of the CLRs implementation or due to memory access patterns.
Ah I came to comment this. Loved the GUI builder in Delphi, it's where I cut my teeth learning to program as a teenager.

Since then, I've seen .NET within Visual Studio almost get to the same quality we had with Delphi in 1995, but still way off.

Now that everything's a web app wrapped in something like Electron, it should be so much easier to have tooling like this, but yet we're all still building hugely complicated HTML rendering pipelines for something that was a solved problem a couple of decades ago.

It's an american view, mostly due to having only experience with ID documents through WW2 movies or cold War propaganda, mixed with religious voices against it ("mark of the beast", wish I was joking).

Elsewhere, "Papers, please" tends to be sign of excessive "stop-and-frisk" or movement restrictions, and the idea of having basic ID card seems to not have much of an opposition. Especially since it's much simpler than sometimes circular requirements of "web of trust" confirmations like in UK (though I heard it got better)

That's the beauty here. It's not the syntax. It's just a syntax to express the abstract thing. Saying this syntax is an issue is like saying "I don't like binary trees because their syntax is so weird". One particular syntax may be weird, but the syntax is only specific to one specific representation. Everybody will be free to choose any representation they like, as long as it can somewhat automatically be translated back into the abstract thing that this project is aiming to produce and maintain.

Why do they want to model mice, when they the whole medical industry don't know shit about the mice they use for experiments?

They use mice to experiment with, BUT through breeding the current lab mice are more resilient then humans. Which can imply that certain drugs getting passed for human testing because they did well with mice. Today's lab mice are more resilient, but the same drug can damage humans.

Because they now offer more content, at a higher quality, with greater convenience than when they first started. It is also perceived as high value socially, something you should obviously have. This wasn't always the case, and the price had to be lower to reflect that - or some people would not pay it.

I'm sure before Netflix raises prices, they ask themselves the question "what % of our subscriber base will we lose, and how much will it hurt the growth rate?"

Presumably, they also do some research. For Netflix, previous subscribers were slowly grandfathered in to the new prices, while new subscriptions paid the full price immediately. I imagine that allowed them to measure the impact on growth and churn before affecting their entire user base, allowing them to reverse the change if they saw it was a big mistake.

Since they haven't reversed the change, one can only assume that it didn't have a big enough effect to justify keeping the previous pricing. Ergo, people consider it to be worth the money. I know I do.

Finally, presumably they arrived at the previous price point by playing with prices, content and advertising until they arrived at a sufficiently large growth rate, so they were at the right price for that time. But many variables have changed since.

Why would a doctor promote Heroin? If they would, especially for recreative purposes, would be very much at odds with any medical ethics. What is clear via Oxy example is that medical ethics really need to be upheld and profit taken out of the equation.

Do you see doctors promoting cigarettes? Alcohol?

I would say that your reasoning why you aren't doing CBD is highly rational. Do you really think that even if you wanted to try heroin and if you did it, it would automatically addict you? Like you're instantly gone in to the abyss?

People try heroin and nothing happens to them. Some even hate the experience. People use heroin for prolonged periods and then simply stop (non unusual in the late teens, with some kind of a trigger in the mid 20).

If there was not so much stigma involved and so much risk taking the stuff, we might see people coming out of this juvenile experimenting phase in a much much better state.

Also, do you really think that people that lifelong addicts, don't have some kind of deeper psychological reasons to go down that path?
