Fun idea, I'll consider adding an extra surprise..

I really like this one! Haven't read the source yet. 1.77mb page size though - I think for mobile it can be better.

You're on :)

You may need to grant microphone access in Settings-->Safari on iOS as well. Or your version of iOS may be older.

Sorry you're having trouble. Are you using iOS Safari? 3rd party browsers unfortunately aren't supported on iOS.

Hi HN, creator here. Lately I've been enjoying learning about the Web Audio API and wanted to apply it. I wanted a quick debugging tool to inspect the sounds I was synthesizing and ended up creating this. It's vanilla JS, so just view source to check it out.

Things I've ended up enjoying with it:

- Hum, whistle, and sing my favorite tunes and compare the images

- Take it on a nature walk and look at bird calls

- Try to make sounds to draw a specific picture or shape

How it works:

On load, the app requests microphone access, and connects that audio stream to a WebAudio AnalyzerNode. The AnalyzerNode offers a fast fourier transform that is called repeatedly using requestAnimationFrame. For each frame, the entire contents of the canvas are shifted left by 1 virtual pixel, and the current fourier frequency bins are plotted in the rightmost column.

Limitations:

- There are 1024 frequency bins, compared to roughly 20,000 hertz hearing range, so the resolution is pretty good but not perfect as each dot represents a range of ~20 hertz.

- Unfortunately doesn't work in iOS Firefox or Chrome; Apple won't offer microphone access via getUserMedia to 3rd party browsers.

- It has a PWA manifest; Android users should be able to add to homescreen. iOS users still can't since getUserMedia is restricted in iOS PWAs

A few years ago I made a similar choice to work for a startup. It didn't work out; I learned that it's probably not worth it unless for me unless I know and am comfortable with the founders, as well as believe in the mission. Less than that brings a lot of uncertainty, compared to a stable high salary I might otherwise earn.

How long did it take to sink to the bottom?

I'm curious how this Facebook VP knows what he knows:

“One in four people in the US have searched for or found a job using Facebook” writes Facebook’s VP of Local Alex Himel.

I'll just leave this here: http://www.metafilter.com/98974/This-isnt-your-grandfathers-...

Although it's important to point out that he wasn't psycho, and his preferences don't seem directly shaped by the treatment..

Appears to exhibit selection bias - what if there is a disproportionately large number of single-founder companies, which fail at a much higher rate than those with 2 or more?

The numbers are interesting, but very misleading. It still doesn't answer whether it's statistically wise to invest in a single-founder company, or help a founder decide how many cofounders they should try to get onboard.

If the strongest conclusion possible here is "Hey there's still hope" then we didn't need all these charts for that sentiment.

Comparison to Tor: https://geti2p.net/en/comparison/tor

It's shown in the data

WALL-E is set in a post-apocalyptic world where the last few survivors who escape to space become lazy and ignorant. When they return to Earth at the end of the movie, they finally realize how much they had lost, such as the ability to dance.

For such a magic pill to exist would be wonderful and I'd love to have that option, but WALL-E as an example undermines your argument...

Update: after playing with this for way too long, I've found that it can converge to a spiral with 3 or 2 or even just 1 node in the 2nd hidden layer.

The 1 node case is especially interesting, because when it converges the single node must learn the whole spiral pattern. Although with noise it can be less reliable with more jagged edges, as well as take longer to converge (also bumped the learning rate down), seeing the spiral encoded directly in the 2nd hidden layer is more interesting to me.

At 25:20 Comey cites "liberty and security" as American founding values, rather than "liberty and justice"

I'm curious where these numbers come from - is it based on your experience, or how is the calculation done?

> The point, though, is that under the right conditions, brain damage may paradoxically result in brain enhancement.

Makes me think of one of my favorite stories: 'Understand' by Ted Chiang. In the story, brain-damaged people treated with an experimental drug gain superintelligence.

This is why you should write tests.

Thanks for the feedback. What in particular did you find difficult or non-obvious about it?

This tiler uses an algorithm that recursively subdivides triangles according to certain rules. Moving the mouse lets you easily see each transformation from the previous. Try clicking anywhere on the page too.

Why is WSJ comparing ridership stats to Nasdaq? Correlation is not causation and this is a stretch.

Does anyone know if a modern version of the "dizzyingly complex" world history infographic exists?

My question too - I wonder how it would perform in normal sunlight.

There aren't even error bars in the article's graphs

I appreciate how the article frames it as a matter of Google preserving their own reputation, as opposed to principle, or it being "the right thing to do." They have been receiving information requests with gag orders attached for years, but are only fighting it now that the cat's out of the bag and they have something to lose. Until then, it seems that Google was fine with the situation as it stood.

I think it's an important distinction to make, and underlines how companies ultimately serve their own self interest before anything else; they're not acting nobly, and the ultimate responsibility lies with the individual.
