aperrien··on Mathematicians Find Wrinkle in Famed Fluid Equations
Thanks, I missed that somehow.
aperrien··on Mathematicians Find Wrinkle in Famed Fluid Equations
Does anyone have a link to this particular paper?
aperrien··on Microsoft Intern’s Rape Claim Highlights Struggle to Combat Sex Discrimination
We've had that, except by word of mouth for most of humanity's history. I think that it's one of the ways we got here, unfortunately.
aperrien··on Microsoft Intern’s Rape Claim Highlights Struggle to Combat Sex Discrimination
Playing devils advocate:

Why should I hire anyone who is accused of rape when I do my background check? Why should anyone else hire such people?

aperrien··on Microsoft Intern’s Rape Claim Highlights Struggle to Combat Sex Discrimination
The downside of this is that reputation systems can be wrecked with rumor. A lie can get halfway around the world before the truth can take the first step.

However, I don't know what's going to work to take people with vast amounts of power out of power for wrongdoing, either. What we've done in the past doesn't appear to have consistently worked. So here we are, unfortunately.

aperrien··on France to ban mobile phones in primary, junior and middle schools
You know it bugs me, but why can't we find the people abusing chat services to do these things? Are there that many of them? I'd like to hope that the percentage of men who are scum is not that high, but recent events have shaken that theory.
aperrien··on Show HN: LibreRead 1.0 – Self-Hosted Free Ebook Reader
If you get a chance, try DocFetcher[0]. I use it for my personal calibre ebook library at home, and I love the fact that between it's independent indexing and the calibre portable distribution, I have a completely portable library on my network.

aperrien··on The Dead Man Fund
I agree. Due diligence is always important, but it often seems that a lot of financial advice seems to say "Don't have anything go wrong in your life, or in your family's life."
aperrien··on Ask HN: What non-work task have you automated?
I wrote a database and interface once that would automatically catalog and run the Safeway Monopoly game, all I had to to was scan in the pieces with an app on my phone. It worked well, but demonstrated just how bad my luck was, after 614 tickets gathered, I won exactly 0 items. :/
aperrien··on Running Bitcoin uses a small city’s worth of electricity
I agree. These out of context questions really bother me, as I have no frame of reference to relate the quantity to to know if it's excessive or not. It just seems like a pure ply for attention. Here are some questions that would make for a better answer:

How much energy do household TV's use?

How much energy does the sports industry use?

How much energy does it take to run our traffic system?

How much energy does the gold mining industry use?

How much energy does it take to run the US Stock Exchange?

At least the article should put up a fair power comparison...

aperrien··on A Brain Built from Atomic Switches Can Learn
I think that this is the same basic concept as a memristor; current flowing one way probes the state, enough current flowing the other way changes it.
aperrien··on Show HN: Build A Personal Power Plant for $200
Try this battery instead, if you want something lighter and more portable:

https://smile.amazon.com/gp/product/B01M3S00H0/ref=oh_aui_de...

I used it while camping for the eclipse, and only had to charge it once every few days, and that was with charging all sorts of other devices as well.

aperrien··on The Worst Internet in America
Much of the time, it's because their parents or grandparents live there. Having family connections makes it hard to move away from a place, unless you like risk.

Which, of course is how those families got there in the first place...

aperrien··on How to make a friend fast
Or living a life with interpersonal conflicts over topics is not something that they enjoy?
aperrien··on Scientists discover evidence for a habitable region on Saturn’s moon Enceladus
I think that what you're describing is some sort of variant of the "Won't somebody please think of the children" rhetorical tool (or the fallacy "Appeal to Emotion"). I don't know what to do about it, but I can recognize it.
aperrien··on HPE unveils The Machine, a single-memory computer with 160 terabytes of memory
I'd guess that it would be close to the size of the adjacency matrix for the human brain, if it is given that the brain has ~1000 dendrites per neuron.
aperrien··on An extra-uterine system to physiologically support the extreme premature lamb
Although I agree that this is unlikely, until we are multi planetary, with at least four worlds/stations, this is not the case.
aperrien··on Saturn moon 'able to support life'
You tell the child that that is a good, but complicated question, and it will take time to give them the full answer. Then you can introduce them to the pieces as they can understand them, and as you have time.
aperrien··on Japan's nuclear technology faces extinction
Have fun with global warming then. I think that humanity needs to come to terms with renewables and nuclear power (with fusion being the best case scenario) for the future of everyone on this planet.
aperrien··on 94-year-old Lithium-Ion Battery Inventor Introduces Solid State Battery
Would this type of battery be useful for grid storage?
aperrien··on Attacking machine learning with adversarial examples
The same sort of tactic can be done with humans:

Nothing (and likely on-one) is foolproof.

aperrien··on The web sucks if you have a slow connection
I think somewhere in that timeframe, standard soundcards adopted support for hardware playback of mp3 files.
aperrien··on Fluid Paint Simulation
This reminds me of Bob Ross and his "Happy Little Trees". I think I could paint some on here if the canvas were bigger, and there was an area off to the side to mix the paint.
aperrien··on Lasers activate killer instinct in mice
I think that the commonly used virus is a variant of rabies, which can definitely cross the blood brain barrier.
aperrien··on The threat of technological unemployment
Medical and Legal dictation specialists, for one.
aperrien··on A Mysterious Virus That Could Cause Obesity
I'm more curious as to what the goal of increasing fat mass would be for the virus. You'd think that it has to be part of its reproductive cycle somehow. Are the viruses hiding out inside of fat cells?
aperrien··on A Mysterious Virus That Could Cause Obesity
No, but a virus could change your appetite, your body's allocation of energy from lean mass to fat mass, or alter your overall metabolism. Or any combination of those.
aperrien··on Human Cells Eat Nanowires
This is interesting, and I guess I have a few questions, for someone knowlegeable out there:

Can these nanowires be fabricated on an on-chip array?

If so, how densely?

I'm assuming that they are electrically conductive, so can we create control circuitry to run them at the previously mentioned density?

Can those circuits be made bio-compatible?

If all there are true, then this might be a good upgrade for existing neural interface devices, depending on longevity.

aperrien··on Western Digital Announces Ultrastar He12 12 TB and 14 TB HDDs
An eon ago, when I was 14, I found out about Moore's Law and computers. I remember writing a Basic program on an Apple II to calculate the results for different years in the future. I boggled at the numbers that came out for these decades, and I am still amazed that it's all kept pace, more or less.

I should see if I still have the program somewhere in storage.

aperrien··on Artificial Intelligence Generates Christmas Song from Holiday Image
How long did it take to go from really silly and obviously impractical flying machine designs to working, practical ones?
