nni··on The Mathematics of Text Structure
good point - but if you actually search for "rabbit chasing dog", you do get a rabbit chasing a dog video - https://www.youtube.com/watch?v=GBYdaPacHJg, as well as some for the other way around

In this case, could you even know which one was actually meant?

Technically, I'd think that the ambiguity is removed when you use "rabbit-chasing dog", but that is assuming the text available is sufficiently precise.

yep - the post-mortems on these things are always interesting
nni··on Electron 4.0.0
I've only very rarely seen performance issues with VSCode...
nni··on D3 in Depth
As far as using other abstractions, you're at the mercy of the developer(s) who made the abstraction, and I've found having to do lots of extra work to figure out how to inject desired customization that makes it generally worth it to just use d3 in the first place
nni··on Show HN: Mindset – Self-Improvement Hypnosis
very cool - trying it out, listening to the first session - hoping I'm not in a Black Mirror episode...
nni··on Show HN: Paper Programs – Run JavaScript on pieces of paper
I've been seeing folks get excited about this, and haven't yet been able to see why it is so interesting. However, the people behind it (Bret Victor et al) and who I've seen playing with it are too interesting for me to ignore this...
nni··on The Impact of Listening to Music on Cognitive Performance (2013)
sorry -here's one I listened to yesterday

- https://www.youtube.com/watch?v=oh-dcCeR-r4&t=6856s

basically, I search for "cognitive enhancement music"- sometimes the "meditation" ones seem nice, too. I have an immediate relaxation response to this stuff, and it's pleasant.

nni··on The Impact of Listening to Music on Cognitive Performance (2013)
What about that ambient/"cognitive/aural beats" stuff on youtube? I've been trying that lately and it seems nice. No data to see if better or not, but definitely more relaxing.

I've also started just using earplugs which can also seem to be (subjectively) effective.

Note: This has not been tweaked for mobile devices, but seems to work (slowly) on an iPad. Built with d3, Mathjax, jstat.js
nni··on Your Life
that is also an interesting idea I may do

You might find this interesting - it adds a bit of dynamicness to it

nni··on Input Appreciated – starting project to quantify properties of “irony” examples
Background:

I have begun a small project whereby I am looking to (subjectively) quantify on a scale of 0 to 10 different properties of images/situations that may be considered "ironic" by some. The current properties include things like "twinge of irony", incongruity, unexpectedness, etc. My longer-term goal is to play with some data visualizations based on the data.

Some rough notes on the origin of this project are at http://thoughtsonirony.blogspot.com/2016/02/towards-subjecti...

You can submit your own example(s) with your own values for the different properties (you don't have to give values for all of them). The example can be an image or the description of a situation. If you want, you can submit your contact info with your example, or just do it anonymously (for now, these values are being posted into a google docs spreadsheet that will be imported later to the list for the site and used as a basis for future data visualizations).

Also - if there are other properties that you think should be included, please let me know.

nni··on Show HN: EmojiViz- Live Emoji Use in Tweets (best on desktop atm)
This is a viz put together based on the streaming data available via Matthew Roth's emojitracker streaming api.

He also has a nice writeup on how he put emojitracker together at https://medium.com/@mroth/how-i-kept-building-emojitracker-c...

emojitracker itself is at http://emojitracker.com/

thanks as well. These are nicely approachable writeups, starting from a basic level.

yes I was having to read the real HN much more carefully right after I played with the simulator

nni··on Show HN: Displaying Lifespan Info in a D3 Family Tree Visualization
I looked again at this and it seems to be correct, based on Wikipedia etc. It's a weird tree that had some serious genetic consequences for Charles II - here's one note on that: http://blogs.discovermagazine.com/gnxp/2009/04/inbreeding-th...

btw, if you "pin" a person so that the popup remains showing, you can click on the name to do a google search of that person.

nni··on Show HN: Displaying Lifespan Info in a D3 Family Tree Visualization
Hi 314

Even for this early version I had debated whether it was worth it to do it for descendant tree due to clutter issues (it can still happen for ancestor trees, but the heuristic limits used make this a little rarer). I'm not quite sure I understand what you're suggesting though - the curves coming into the top do terminate at the birth year, but the node itself kind of covers this up - is that what you're referring to?

A little background info about this is at http://www.nowherenearithaca.com/2015/07/displaying-lifespan...
nni··on ES6 in Depth – Symbols
It is my understanding that symbols were going to be a way to have private methods. This aspect of them - the reason they were going to be introduced in the first place - was dropped, and so you are left with its current limited form with a much narrower use-case.

From A Rossberg (he's also the guy behind SoundScript) in a March 2014 stackoverflow post (http://stackoverflow.com/questions/21724326/why-bring-symbol...):

"Enabling private properties ... was indeed the original motivation for introducing symbols into JavaScript. Unfortunately, however, they ended up being severely downgraded, and not private after all.

They are now known as unique symbols, and their only use is to avoid name clashes between properties....Whether that is strong enough a motivation to add symbols to the language is debatable."

and from R. Waldron as part of this response (https://esdiscuss.org/topic/proposal-about-private-symbol) to a proposal about a private symbol (Dec 2014)

"Ultimately it was decided that Symbol is just a symbol and that "private" things will be dealt with orthogonally (and at a later date)."

YMMV

those glow effects are sweet - the whole thing is inspiring and motivating

while it's nice to look at, I had the same impression - maybe there's a critically missing additional note or something that would help clarify this.
nni··on Show HN: (Beta) tool to quantify one's blue&black/white&gold "dress" level
A few notes on this (with the app embedded on the page) : More than a Meming? The Color of a Dress, an Interactive Tool, and Our Interpretation of Reality - at http://www.nowherenearithaca.com/2015/03/more-than-meming-co...
nni··on Can you save yourself a lot of time on HN by applying Betteridge's Law?
Irony :)
nni··on Show HN: (Beta) tool to quantify one's blue&black/white&gold "dress" level
Note: this blue&black vs. white&gold dress "illusion" (and probably quickly fading meme) is fascinating to me because it highlights how we might be interpreting reality differently without even knowing it.

The beta tool just provides an (imperfect) way to try to quantify where one might be on the scale of being a blue&black or white&gold - and I think it is a scale because I have read how some people even looking at the original image might have it flip back and forth.

nni··on Show HN: Exploring Family Trees/Pedigree Collapse – Interactive D3 visualization
btw - "chronologically adjusted" is the concise phrase I was looking for when describing this
nni··on Show HN: Exploring Family Trees/Pedigree Collapse – Interactive D3 visualization
thanks for taking a look - will see about implementing that as well
nni··on Show HN: Exploring Family Trees/Pedigree Collapse – Interactive D3 visualization
Note - you can also load your own GEDCOM file for your own family tree or use one of the samples. The British Monarchy one demonstrates the pedigree collapse mentioned in the title of this submission.

Also, hovering on the nodes shows a popup on that person

This is very much a work in progress.

nni··on My Amazon S3 Mistake
For Amazon it is certainly possible, imo. They just don't do it, AFAIK. An alert that you might or might not get is obviously not as reliable as a hard limit.
