falkenb0t··on Space Shuttle teleprinter reverse engineering
Not exactly a primary source but according to this thread: https://forum.nasaspaceflight.com/index.php?topic=10617.0

"Toner is held to the paper in a laser printer by electrostatic attraction (opposite charges attract), not gravity. Along those same lines, in an inkjet printer ink droplets are fired at the paper, not just dropped, so once again I doubt gravity is an issue."

falkenb0t··on The ethics of reclining airplane seats
I've personally flown a ton of American domestic flights and have never encountered someone who threw a tantrum over reclining seats. In fact, prior to this post, I didn't even realize it was something some people frowned at.

Anecdotal, of course, but then this entire thread is fairly anecdotal.

falkenb0t··on Ask HN: How do you deal with rude interviewers?
I had a very similar experience (though not quite as extreme) with a Comcast interview. The interviewer would ask me about my experience and either cut me off before I could answer or practically insult me when I would give an answer to the effect of "I don't have experience with this specific technology but I do have plenty with this equivalent tech." It left a bad taste in my mouth afterwards but honestly, like many others are already saying here, that guy did me a favor by letting me know right up front that I would not like working there.

I was fortunate in that it was only a 30 minute phone interview so I could just grit my teeth and wait it out but it is entirely reasonable to terminate an interview if you are not being given respect.

falkenb0t··on Introduction to K-Means Clustering
I found myself having to do some clustering a few months back and learned about mean-shift clustering [1]. I found it to be a nice clustering algorithm for when you don't know quantity of clusters ahead of time.

That said, its worth noting that there are algorithms out there for determining optimal number of clusters for k-means (though personally I found them to be costly and subject to overfitting) like using the silhouette coefficient or elbow method [2].

falkenb0t··on Show HN: Person Identification by Keyboard Typing
He very well might be interested. I'll shoot him a message and let you know if he is
falkenb0t··on Show HN: Person Identification by Keyboard Typing
Funnily enough, I had a classmate in my grad neural networks class that did exactly this. Results on his end seemed to be pretty similar to yours though I don't think he publicly hosted it anywhere

Regardless, this is an interesting application of NNs

falkenb0t··on OpenAI Five
It is essentially the same frequency of links that you'd see on any Wikipedia article. In a field where there is an enormous amount of jargon, it is probably a good thing that they clearly define as much as possible.
falkenb0t··on Impact – HTML5 Game Engine
was there a title change? the link goes directly to the github page.
falkenb0t··on A journalism student who found out she won a Pulitzer in class
wow, that really does hurt to read.
falkenb0t··on OpenAI Retro Contest
No, you're not wrong. That said, I don't think this is a competition aimed at people with a beginner level knowledge of machine/deep learning. I don't believe there is currently any MOOC that is going to hold your hand from 0 to expert. Given the current state of the field, I believe the only surefire path towards this level of knowledge is either university education or a /lot/ of reading.
falkenb0t··on Spotify Form F-1
Anecdotal but mine have been pretty great. Of course there are songs that I'm not a fan of but for the most part its recommendations have been spot on.
falkenb0t··on Is Machine Learning/AI Sexist?
The author cites word2vec as being biased and gives the example of it associating the 'father' with 'doctor' but associating 'mother' with 'nurse'

While this is certainly a bias, I think the insinuation is that this makes a program inherently sexist or racist.

I don't think anyone would really call the statement "in today's society, certain professions are male dominated" particularly sexist.

What I'm getting at is that I think there is a distinction to be made here where bias introduced via training data doesn't necessarily translate to sexism or racism.

Additionally, the problem doesn't as much exist in the programs as they do in the training data. No engineer at Google sat down at their computer and went "yep, men are doctors and women are nurses. Better program that into word2vec". That behaviour was learned from the information available.

falkenb0t··on Facebook Hits 2 Billion Users
That is mind-blowing. 2 billion total users an immense volume in and of itself but 2 billion even semi active users is incredible
falkenb0t··on Facebook Hits 2 Billion Users
That's mind-blowing to me. Is that correct that roughly 26% of the world population is on Facebook? Or are these numbers representative of total users since the beginning of the site?

If it's the latter, then I'd be curious as to how many users actively use the site today.

falkenb0t··on Academics argue over how many people read and cite their papers (2014)
Yeah, especially when you consider all the current buzz about Neural Networks. The original papers on MLPs, CNNs, etc were published more than two decades ago but were not given much attention until recently.

And I certainly wouldn't consider that a failure.

I'm sure there are other examples of research catching on decades later.

falkenb0t··on Introducing DarkSky.net
I think it just defaults you to New York on forecast.io because I'm getting that when I load the page and I'm located in San Diego

Depends but there are computer vision techniques for deriving depth from two or more calibrated cameras. It may not be super accurate but it is likely do-able.
falkenb0t··on San Diego Struggles to Keep Its Young Tech Talent
Can confirm: currently live in Rancho Penasquitos and it's great if not a little suburban. That said, if I were a little older and had a family it would be perfect.
falkenb0t··on Only Apple could get away with killing the headphone jack
Yeah, that's more wishful thinking than anything else
falkenb0t··on Only Apple could get away with killing the headphone jack
I appreciate the idea that Apple is able to take bigger risks based on their secure position in the market but it is still hard to look at this move as anything more than a means to force more users to buy Apple brand headphones.

Granted, I have no idea what an 'upgrade' from a headphone jack to thunderbolt port could imply. If it is possible to increase sound quality through thunderbolt or reduce phone costs based on the absence of a second port then I'll gladly welcome the change.

I guess their justification for doing what they're doing remains to be seen and time will tell.
