greendestiny··on Why fuel cell cars don't work
Fuel cells require massive infrastructure before a single FC car can be sold openly. BEV can saturate the market of people with access to parking and power right now - and that's not a small market.

The FC vs BEV fight doesn't start when FC enters the market, it's already on and FC is losing.

greendestiny··on The Fermi Paradox
Another example I hate is the probability of reality being a simulation thought equation. If these equations had some confidence interval based on how little we know it would be clear how meaningless they are.
greendestiny··on Single-shot compressed photography at one hundred billion frames per second
Yes it is compressed sensing. Compressed sensing is where you have an input that is randomly 'combined' and then you reconstruct the signal you want (it has to be sparse in some way) using the L1 norm.
greendestiny··on Google Lifts the Turing Award into Nobel Territory
Well a Nobel prize is awarded for the significance of the breakthrough, and the Turing award is more for the significance of the person. I think it would be good to have an award in computer science that celebrated and validated breakthroughs (though it doesn't have to be the Turing award).
greendestiny··on Tim Cook Speaks Up
I tend to think most people look on something like that as an opportunity to score a win for what they believe in rather than genuine concern at his actions as CEO. Some of the decision to let him resign must have come from the lack a successful strategy to respond to it though.
greendestiny··on Lab Notebook: Single Pixel Camera
It's a dense sensing of the radon transform - hence its not compressive. But you can resample that lots of ways and satisfy the RIP. Reconstruction of images from sparse radon transforms is one of the early examples that helped shape the field.
greendestiny··on Lab Notebook: Single Pixel Camera
You might technically correct in the limited sense that this isn't a 'compressive' sensing - but it's an absolutely classical example of sparse reconstruction. You can resample that radon transformed image randomly and reconstruct it as a sparse fourier image. There is matlab code out there if you google around a bit.
greendestiny··on Exploring No Man’s Sky, A Computer Game Forged by Algorithms
Games are played and any amount of variation that isn't reflected in the game play is quickly filtered out. It isn't a problem of better sliders or more sliders or more realistic ranges of results, it's about the variation in gameplay they produce. The variation in game play is all down to the rules of the system and how the generated world influences that.
greendestiny··on Large Round of Layoffs Expected at Microsoft
When whom to layoff is a political decision, layoffs will just compound the problem.
greendestiny··on The Body on Somerton Beach (2011)
I took a stab at using google's n-grams library to look at potential sentences if the code was an initialism. It generated too many nonsense values at the value of 'n' that I picked (driven purely by download size concerns really) and any kind of names or codes or abbreviated language wouldn't have worked well with that approach.

I think at some students of the mentioned Prof. Abbot looked at the letter distributions and found the highest correlation with an english language initialism.

greendestiny··on The Highest-Paid CEOs Are The Worst Performers, New Study Says
Yes I think this is a simpler correlation. Bigger established companies have more cash to pay the CEO but less room for growth. The companies themselves are probably more concerned with minimizing risk and holding position - it might be a better study to compare CEO pay with board evaluation of performance.
greendestiny··on What the Theory of “Disruptive Innovation” Gets Wrong
I think innovation and the disruption it brings is real - but I think this article does a good job of arguing that the inability of incumbents to respond is overstated by the theory and its proponents.

Intel hasn't closed down and given a few years may be stronger than ever.

greendestiny··on Drop Dropbox
No I think people like to defend things associated with people or startup incubators they like. So in a sea of negativity they latch onto any argument in favour of the thing despite its lack of merit.
greendestiny··on Drop Dropbox
I agree with you. I think grellas argument is so flawed that the only reason to make it and upvote is as distraction and current best defense while the dropbox team works on something more believable. The backlash against Rice is over her actions, not her beliefs, and has a tangible connection to matter of great concern with cloud hosting - which is government sanctioned data collection.
greendestiny··on Dai/Nakamoto emails
It's the worst date faking attempt in history if that was his intention - I think he republished his 2005 story after bitcoin to point out that he came up with these ideas.
greendestiny··on Wrong and Right Reasons To Be Upset About Oculus – with Carmack response
I feel like we've gone full retard about the potential of VR again. Facebook has bought a promising headset technology, but we're a long way off people living in a virtual world controlled by Facebook. While I fully expect Facebook to data mine any hardware they control I'm not certain how it corresponds with the nightmare vision here.

If anything Facebook buying Oculus so early is a good thing for people scared of Facebook's impact on VR. I think there is a long and involved period of VR being refined by hardcore gamers before it tentatively ventures into virtual sports and virtual meetups et al. I just don't see the big gaming companies wanting to do deals with Facebook - they hate Steam for its platform control and its communication overlays - they'll be very wary of a Facebook chat overlay finding its way into to Oculus driver v1.2. And I just don't think Oculus as funded by Facebook is going to be living or dieing with gamers feedback like they would as an independent company. I doubt they are going to sacrifice enough to meet those demands and be reshaped by them.

greendestiny··on Nick Szabo is Satoshi Nakamoto, the Inventor of Bitcoin
Statistical analyses rely on assumptions of sample independence and random selection that are pretty hard to justify with something like this. Are all the articles on the same topic? Are they written for the same audience? Are the works independent or is there copying and/or inspiration being shared?
greendestiny··on Satoshi Nakamoto denies being Dorian Nakamoto
c. Hiding out at his kids house where he doesn't have his keys handy but knows his password.
greendestiny··on Famous tech acquisitions’ cost per user
What they saw was youtube.
greendestiny··on Project Tango
Do you mean the accelerometer values drifted over time (i.e. the direction of gravity shifted on a stable accelerometer) or do you mean the value when doubly integrated drifted?
greendestiny··on Why don’t software development methodologies work?
Yeah that was a little bit optimistic about the powers of Agile for me, but I think the thing that Agile gets right is that we all have to operate under the uncertainty of the scope of software projects. In that sense it's not a methodology for estimating the complexity of a software project but a way to start working without that.

Perhaps the biggest reason this keeps causing problems is that companies have no good way of dealing with change. If you expect to finish any project that you start then you need to know more about that project than is realistic at the time you start it. A canceled project is a big failure for most employees and not something they want to happen to their careers.

greendestiny··on Georgia Tech Researchers Reveal Phrases that Pay on Kickstarter
I know your comment was mostly a joke but thats actually a great distillation of the paper. Apart from not caring about a Christina Aguilera documentary, it does seem like a powerful pitch to me. I guess it reads somewhat more like an request to help make something happen that otherwise wouldn't rather than a presales channel.
greendestiny··on Fermi Paradox: If the Universe Is Teeming with Aliens, Where Is Everybody?
If these civilisations find some way to communicate or interact at all you can't treat them like independent variables.
greendestiny··on Why I don't trade stocks and (probably) neither should you
What if every fund manager had a certain non-zero level of skill - but the market price was such that the mean skill level returned no profit (or the risk free return rate). I guess this is more or less the efficient market hypothesis - except if you follow it through I don't think it says that there is no skill in stock picking - just that the skill is undetectable. Under those conditions a random strategy should do as well as the mean - and the mean return will simply be the average market return.
greendestiny··on Drowning in JavaScript
Seems like an inverse correlation between the ability to make money online and the number of libraries.
greendestiny··on Dear Startups: stop asking me math puzzles to figure out if I can code
I think you're still suffering from same mindset that led to the problem described in the article though. He wasn't a mediocre programmer - he was a bad programmer. If you make a lot of assumptions about people in an interview you will probably be disappointed.
greendestiny··on Lumitrack: Low Cost, Precise, High Speed Tracking with Projected m-Sequences
Head tracking would definitely be one. Although rough position tracking with accelerometer rotation tracking might work just as well. Still these are much lower cost than all the hardware that went into the wiimote head tracker.
