datashovel··on How to Fall 35,000 Feet And Survive (2010)
There's probably room here for a niche consumer product. Something that one could wear on a flight discretely, that would behave as a makeshift parachute should one find oneself in this circumstance. If it were cheap enough (and not ridiculously uncomfortable) I'd probably consider buying one.
datashovel··on Sorites Paradox
So if I understand correctly, then twigs and leaves could be boats? :) I guess if a boat was originally constructed of a bunch of twigs (some of which still had leaves on them), but caught on fire. One lucky leaf was knocked off and managed to survive the fire. Everything else sunk. The single remaining artifact of the boat was that one leaf. And it's still floating... Everyone looked at me perplexed when I told them all that we were looking at a boat! :)
datashovel··on Why Apple Music is So Bad When the iPhone is so Good
vibrate-only alarms don't work. The UI allows you to set no sound, and choose a vibrate pattern, but it doesn't trigger when it's supposed to. I learned that you have to create and load a "silent.mp3" file and select that sound for the alarm in order to get vibrate-only alarms to work.
datashovel··on Europa's Ocean May Have an Earthlike Chemical Balance
How confident are scientists that life on Earth began in the conditions of present-day Earth?

I don't think they were trying to assert this necessarily (that the current conditions of Europa were necessary and sufficient for life to exist there), but I just wonder this every time I read about space exploration and the fact that scientists are seeking planets that have an earth-like atmosphere.

Personally I'd want to know (a) what conditions caused life to begin on earth, then and only then (b) which planets have, presently or in the past, similar conditions.

All the talk about looking for earth-like planets to find extraterrestrial life could be a big waste of time if we eventually learn that present-day conditions on Earth are not conducive to creating the fundamental building blocks for life, no matter how good it has been at sustaining it.

UPDATE: Sorry, just noticed I mention atmosphere in my comment. That's a mistake. I was thinking 'earth-like conditions' (which is more or less what's mentioned in the article), but I typed atmosphere.

datashovel··on Why Apple Music is So Bad When the iPhone is so Good
I don't think it's just the "internet services" that they need to take more seriously. Ever since I bought my iphone (about 1 week ago) I've had an itch to write a blog post about my first experiences using their Clock app... Their CLOCK app :)
datashovel··on Sorites Paradox
To describe this concept I've always used a boat as the subject.

Imagine you have a boat. Now take a piece off of it. Is it still a boat? How far can you go until it no longer holds the distinction of being a boat?

datashovel··on Apple R&D Reveals a Pivot Is Coming
I think the ideas presented appear somewhat contradictory. I may be missing something here because the following 2 ideas seem contradictory to me.

1) Apple's secrecy 2) Apple's pivot

If they're pivoting, why be secret about it? One of the reasons provided was that being public about new products could hurt current product sales.

If it's an entirely new product line (ie. car), I have a hard time believing someone will think twice about buying an iPhone because Apple is coming out with an electric car.

Instead being secret seems it may hurt more than help. If I'm in the market for a new car, and there's a real release of an affordable Tesla that has already happened, while at the same time I have no idea what Apple is doing or if they're even going to do it or what kind of timeline the project is on, I'm probably going to buy the Tesla.

Otherwise if I'm somewhat certain that Apple may be coming out with a new car within a year or two, I may decide to hold off with my purchase of the Tesla for the time being in order to consider buying the Apple iCar when it comes out.

I'm sorry, that you could read this entire thread and come to such a conclusion.
datashovel··on Economist Removed from Plane for Algebra
To be honest, it is threads of comments like this that make me wish HN had a Mute or Block option.

I apologize, but it's just not worth continuing this conversation because we are talking about completely different things.

datashovel··on Economist Removed from Plane for Algebra
When I read responses like this (that have no connection with the comments they're in response to) I have to just assume that Hacker News has switched out my comments and replaced them with something completely different.

Please let me know if you manage to catch the witches you appear to be hunting.

datashovel··on Economist Removed from Plane for Algebra
It's likely you were not among those this post was directed toward. Sorry for the confusion.
datashovel··on Economist Removed from Plane for Algebra
Please read the post again. It's clear you've jumped to conclusions. Perhaps you're not among those who this post was directed toward?
datashovel··on Economist Removed from Plane for Algebra
On a more reflective / somber note. I am a huge fan of the idea of empowering all classes of people. So the fact that this lady was able to disrupt the flight is I think (big picture) a good thing.

Instead of simply dismissing this person as ignorant, I hope folks on this forum will take a moment to reflect on the tragic state of the entire system. If we're going to enable / empower all classes of people we (those in a position to make a difference) need to do a better job of raising the bar, and helping all those in need to raise their own bar too.

Do you think this would somehow exonerate the "concerned citizen"?
datashovel··on Ask HN: Clean code to learn ML feature-extraction techniques
BTW, having a look at your link just now. This will be very helpful. Thank you.
datashovel··on Ask HN: Clean code to learn ML feature-extraction techniques
Thank you for the insights. I have not implemented a CNN yet, but is certainly on my radar. In fact other reading the other night pointed me in that direction so I am exploring that at the moment. With regard to scale and/or efficiency of the algorithms, I would guess if anyone is wrong here it would be me :)
datashovel··on Ask HN: Clean code to learn ML feature-extraction techniques
Thank you for the link. I will look into this. Some of the reasons I get the idea I need to incorporate this additional step (feature detection) are:

1) I'm building this primarily for a robot, so my impression is that by building up a set of primitive features, and building up on top of them, will be more efficient for soft real-time use cases.

2) I have done what you suggest (more or less), for example as a test with the MNIST Digit Classification data. I was only getting approx. 95% success rate using this basic technique, which at first glance appears impressive until you realize what is considered "state of the art".

3) My goal is to also incorporate additional layers of data (which I'm under the impression will help improve my overall success rate), such as edge detection, corner detection, and most importantly 3d data (ie. distance from camera based on data extracted from Google Tango), so if I'm correct about #1 where this will be a more efficient calculation, incorporating all the additional data (and extracting features from that as well) will slow things down only incrementally.

datashovel··on When Lobbying was Illegal
Lobbying: Where rich people have free speech while in an office (or on a golf course) with their Congressman. And poor people have free speech in the comfort of their home.
datashovel··on How three connected hardware companies killed their devices
It seems the IoT community should push for manufacturers to provide up front guarantees that if they discontinue a device / platform they will open source the entire system for the community of users to continue as they wish.

That way first adopters will feel safe in their purchases no matter what the outcome.

datashovel··on Sci-Hub, spiritual successor to Aaron Swartz, angering publishers all over again
Perhaps controversially, I'd say this is one of the biggest problems facing the world today (ie. inaccessible research papers).

Where is the real money and influence that we need in order to change this?

I could certainly see "pull requests" happening for collaboration on open documentation / manuals / reference guides, etc.

datashovel··on Hedge Funds Pumped Up Silicon Valley, Now They're Pulling Out
Why own shares of a valuable business when you can buy the entire business for pennies on the dollar when they're about to go bankrupt?

EDIT: Then sell them during the next bubble.

datashovel··on I've Just Liberated My Modules
Open source community needs to aggregate a list of lawyers who will consult on these sorts of things (related to the community at large) pro-bono. This way all parties on the open source side can feel a little less pushed around and bullied and a little more protected.

The best part would be to learn that the claim was not valid in the first place. At the very least, having representation would provide for some wiggle room where you can have days if not weeks to resolve the issue, instead of feeling you have to take immediate action.

datashovel··on My Take on FBI's “Alternative” Method
A little off topic, but I was wondering what kind of "wear and tear" occurs on a phone at the molecular level? I imagine a phone with a "pin" verification will be tapped fairly regularly in certain places on the screen (especially if the user never changed their pin).

Also wonder if any of that "wear and tear" would show up in the circuits that detect taps. Again, if only specific places on the screen are tapped for the pin (never changed) it may leave enough evidence somewhere somehow at the molecular level.

Anyone here with knowledge in this area that could debunk or validate this concept?

datashovel··on NSA data will soon routinely be used for domestic policing

  They lose nothing by fighting you in court.
I am 100% certain you are wrong about that.
datashovel··on NSA data will soon routinely be used for domestic policing
I would not be surprised if there are crowdfunding sites that help fund lawsuits or other legal matters.

Are there crowdfunding sites that help fund civil rights cases?

Edit: In other words, I'm beginning to think the only way to chip away at this sort of massive government overreach is to crowdfund the hell out of a ton of legitimate civil rights cases. Eventually maybe our government(s) (since I imagine US is not the only one to be concerned about) will get the hint.

datashovel··on Different parts of the brain work best at different ages
I have a theory that there are different types of brains that peak on different cognitive skills at different ages. So while I think it's a noble effort to find the average and standard deviation of the entire population, I'd be more curious to see if they can't find clusters of different types of brains that behave similarly but perhaps very differently than the "global average".

"Congress is still holding hearings that lead nowhere"...

And who continues to vote incumbents into office? It's as if we have no one to blame but ourselves.
