sprucely··on Ask HN: Is 23andMe DNA testing worth it?
I guess I was trying to suggest in a tongue-in-cheek way that gp's comment might be disingenuous or contain some sort of fallacy. I mean, there are plenty of ways that drug companies can benefit or be a scourge on humanity. Just consider the EpiPen pricing debacle. Is it a benefit to humanity when the demand for a life-saving product is leveraged to maximize profits, extracting the livelihood from the people it's supposed to be saving?

Are you saying that developing novel treatments is the sole purpose of a drug company?
sprucely··on Ask HN: Software development after 40, how do you keep the fire?
Does being a new parent of twins in my mid-forties count as managing a serious medical condition? I don't have anything to back it up, but I feel your situation is more the exception than the rule. I would like to be proven wrong. I keep plugging away at side projects when I get a chance to take a breath. But even then, it seems to take tremendous effort to get into any kind of productive zone.

Went to one of his concerts a couple years ago. Except for his vanity, it was one of the best shows I've ever been to. A lot of fun.
sprucely··on When Not to Serialize
How about FlatBuffers, making the file format and in-memory format one and the same?

sprucely··on Decentralising the web: Why is it so hard to achieve?
I like to read the discussion boards for MaidSafe from time to time. [1] In their case at least, serving content would not be mandatory to benefit from the p2p aspect. That's for those running a vault. And even then a vault wouldn't know what it's serving to whom. Nor would the recipient be able to determine the IPs of any of the vaults it connects to.

On the performance side, I think that depends on what's being attempted and how. MaidSafers like to reiterate the notion that popular content will have chunks cached more broadly across the network, but that is only one aspect. There are other things that are not intuitive about how to develop a distributed application with no central authority. And their current model does not include sharing computing power (no Function-as-a-Service type of thing); just storage and bandwidth.

sprucely··on SAFE Network: a decentralized data storage and communications network
It has no blockchain, but it does have something called a "datachain"[0] that allows among many things, proof of group membership and recovery from network churn and outages. Here's a more in-depth description.[1]

sprucely··on The Bitcoin Flaw: Monero Rising
SafeCoin would be if it were actually implemented. As it currently stands, there is just a MaidSafeCoin token with a promise of a 1:1 exchange when SafeCoin gets implemented. Still, the concept is interesting. It's not blockchain-based, and a coin's data structure only contains the current and previous owner signatures.
sprucely··on Monsanto Attacks Scientists After Studies Show Trouble for Its New Weedkiller
My understanding of beans is that it is possible, but not commercially feasible. Something about the yield of seeds per plant versus the effort to control the crossing of parental inbred lines.
sprucely··on Monsanto Attacks Scientists After Studies Show Trouble for Its New Weedkiller
Most commercial varieties these days are hybrids. Many of the desirable traits are fixed for the plants that grow from that "F1" generation. But if you try to plant harvested seeds from those plants ("F2" generation) you'll get inconsistent results. It's possible to isolate particular traits via selfing and selecting for those traits. It's a years-long process, but I could see that happening in countries not beholden to Monsanto or trade deals.

sprucely··on KeePass 2.37 has been released
Autotype bypasses the clipboard. It works well, particularly for those annoying login pages that prevent pasting from the clipboard.
sprucely··on Unity 2017.2 is now available
I've been following Godot for some time. Development of 3.0 is progressing nicely and looking to have some great features... C#, GDNative (script bindings for other languages: D, Rust, etc.), asset library, a more modern graphics pipeline

My understanding is that those coming from Unity often get tripped up by Godot's scene/instancing system because it's somewhat different than how prefabs work. Subtrees in a scene can be broken out into a separate scene and instanced. Elements as basic as a bullet should be implemented as a scene and then instanced and customized as needed. A common sentiment I've seen is, once it "clicks," they can't imagine going back.

I've only spent a few hours in Godot since recently cloning/building the master branch, and I already have a nice force-directed graph implemented. If it gets to a point where the number of graph nodes affects performance, I can move the force calculations from GDScript to cpp or another native option.

sprucely··on Ask HN: Which scifi authors to interview about immortality?
His Night's Dawn Trilogy also explores souls coming back to possess the living.

Does GetEventStore[1] fit the bill?

sprucely··on AI-Powered Drone Will Follow You Around and Take Pictures
The sci-fi trope of small drones effortlessly tracking fugitives seems to be inching towards reality. I'd guess it would be pretty easy for it to start following the wrong person if there are too many moving objects in range. But the tech can only improve from here.
sprucely··on LastPass: Security done wrong
KeePass also has a handy feature that bypasses the clipboard and sends {username}{tab}{password}{enter} keystrokes directly to the browser window. The keystrokes can also be customized per web page.
sprucely··on SpaceX Iridium-1 Webcast [video]
Anyone else notice the tumbling object ahead and to the left that appears at about 34:38? https://youtu.be/tTmbSur4fcs?t=2078
sprucely··on Ant species cultivates coffee for accommodation
I've watched crows drop walnuts above a road and immediately dive to pick up the cracked shells before the waiting magpies can swoop in. Both appear to be learned strategies.
sprucely··on Russian propaganda effort helped spread ‘fake news’ during election, experts say
There is only one thing I can think of that would be worse than the spread of fake news, and that is legislation to address the spread of fake news. Unfortunately, that's where this is leading; if not in the Trump administration, then in the following.
sprucely··on Ask HN: Is Dell XPS Developer Edition a Good Replacement of Macbook Pro?
It does on my install of Ubuntu 14.04 LTS
sprucely··on Nice People Really Do Have More Fun
Not necessarily anyone. Personally, I am becoming more aware myself that when I'm criticizing someone, even indirectly, it's often coming from a desire to elevate myself above them. Think about all the other idiots on the road when you're driving. They're terrible. Thank the heavens you're so much better than them.
sprucely··on Nuclear Pulse Propulsion – Orion and Beyond (2000) [pdf]
That's what Breakthrough Starshot[1] is about, although scaled down to very small probes. I like the probe concept. If we really don't want all our eggs in this one basket, it seems to make more sense to put effort towards tech that can spread our seeds (whatever that may be) rather than humans physically traveling.

sprucely··on How to be mediocre and be happy with yourself
That's been my situation. Rather than making just another crap platformer for my first game more than two years ago, I started something a little too ambitious for my experience and available time. And although I basically finished the final touches (introductory tutorial) last night, I'm not certain it will become popular enough to warrant additional effort to enable monetizing through in-app purchases. (It's a rather zen game of flow, and ads would be too intrusive)
sprucely··on Why swearing is good for you
For those who are not very creative with their expletives, there are plenty of resources out there. A quick search led me to this... http://foulomatic.hnldesign.nl/
sprucely··on FBI Makes Official Its Decision to Keep Apple iPhone Hack Secret
How could any information obtained in such a way be useful to them, as there is no way to prove it is not tainted (chain of custody and all that?)
sprucely··on The Curious Link Between Fly-By Anomaly and the “Impossible” EmDrive Thruster
Not sure I fully understand about jumps in quantized wavelengths of Unruh radiation, but it's nice to see some testable predictions. Can someone smarter than me comment on the assumptions made by this theory; that photons have inertial mass and that the speed of light must change within the cavity?
sprucely··on Zuckerberg, Milner, and Hawking to Launch Nanocraft Project
This seems pretty cool. It fits in nicely with the Sci-Fi trope of sending machines with our genome out to other star systems where they proceed to print or otherwise grow a colony; a little far-fetched, but not nearly so much as humans traveling to the stars.
sprucely··on Android creator Andy Rubin is making a free dashcam
The paranoid in me says we don't need yet another surveillance channel. But the public loves "free" stuff enough that this just might be successful.
sprucely··on Cops hate encryption but the NSA loves it when you use PGP
Sounds a bit to me like part of a FUD campaign or at least bluster to scare off people from seeking out tools that help protect privacy. But it does highlight a need for these tools to become more ubiquitous.
