"In Washington State, Bill Gates, Sr. advocates for funding education for future generations. He proposes using inheritance taxes." - Todd Hoff from Bookmarklet
He's been advocating their use for quite some time - as he puts it, it isn't like he's worried about how well his kid is going to get along after he's gone. - Jennifer Dittrich

"Cloud droplets are, for the most part, dew which forms on tiny dust and salt crystals which are blown by the winds . These particles are called condensation nuclei and are so small that they can be seen only under an electron-microscope with a magnification of several thousand times. The most efficient condensation nuclei result from the evaporation of water from tiny droplets in the spray from the ocean; however, other condensation nuclei are the result of combustion, even if no smoke is visible."

"In their new paper, the MIT researchers show that so long as the number of clusters required to describe the variation in a population is low, collaborative filtering yields nearly optimal predictions. But in practice, how low is that number? To answer that question, the researchers examined data on 10 million users of a movie-streaming site and identified 200 who had rated the same 500 movies. They found that, in fact, just five clusters — five probabilistic models — were enough to account for most of the variation in the population." - Todd Hoff from Bookmarklet

How a Memory Is Made | The Scientist Magazine®
"“It never ceases to amaze me that we know enough about memory to be able to channel specific memories to specific cells,” said Silva. “We are able to genetically engineer the insular cortex so that we can determine ahead of time which neurons will be engaged in which memory. To me, that’s really magical.” On the other hand, he said, these experiments are “limited, because in the real world, real memory is not about single strong memories.” Rather, said Silva, we remember events as “strings” of individual sensory memories. He said his team is now working to understand how these strings are formed, and CREB clearly plays a part. For Costa-Mattioli, the demonstration that similar processes control memory allocation in different parts of the brain is “very tantalizing. . . . Perhaps this mechanism allows the strengthening of connections between brain areas.”" - Todd Hoff from Bookmarklet

"Claudia Schnugg: This development, to create a three dimensional objects from changes of physical three dimensional objects over time (e.g., how objects, arms or legs change while moving through a room) is extremely interesting if you think of Daniel’s work in its bigger context. He first developed static pictures that show how slices of the world change over time. Based on that he developed videos that were able to demonstrate time through this technique in a way that addresses more senses. Real Imaginary Objects is now the next step, where Daniel develops sculptures that show time as manifestation in the real world that can be touched and viewed from any perspective." - Todd Hoff from Bookmarklet

"Archaeologists discovered three unique mosaics at the Ancient Greek city of Zeugma, in south Turkey, near the borders of Syria. The ancient city of Zeugma was originally founded as a Greek settlement by Seleucus I Nicator, one of the generals of Alexander the Great, in 300 BC. The population of the city at its peak was approximately 80,000 inhabitants." - Todd Hoff from Bookmarklet
They're beautiful. (I wonder why a sea goddess has wings attached to her forehead? (Oceanus' lobster claws make total sense, of course.)) - Eivind
Symmetry? The wings and the claws parallel each other. And as they spring forth from the head, perhaps it's a sign of divinity? - Todd Hoff
Just seems like a deviation from the aquatic theme of her hubby/brother's protrusions and her sea serpent necklace. - Eivind

"Crossing the threshold from unawareness to awareness [could be] a reflection of bound crossing [in the integrator]. In this way, the integration-to-bound theory may help to resolve the contradiction between the subjective report of free will and the requirement for causal antecedents to non-capricious, willed actions. …our results provide a starting point for investigating mechanisms underlying concepts such as self, will and intention to act, which might be conserved among mammalian species" - Todd Hoff from Bookmarklet

A Much Cheaper Grid Battery Comes to Market | MIT Technology Review
"A new kind of battery that stores energy from solar and wind power cheaply and cleanly has hit the market. It is by far the cheapest of a new generation of large, long-lived batteries that could make it possible to rely heavily on intermittent, renewable energy sources. Aquion Energy, a company spun out of Carnegie Mellon University, recently delivered the first of its batteries to operators of small power grids, or “microgrids,” that can operate independently of the centralized grid." - Todd Hoff from Bookmarklet
Earth has warmest October on record as ocean temperatures top charts -

"Multiple datasets have confirmed it was the warmest October on record for the globe, keeping the planet on a course towards its toastiest year. The Japan Meteorological Agency, NASA, and the University of Alabama’s temperature records all showed October temperatures at the top of charts." - Todd Hoff

Changes in U.S. precipitation: wet areas to get wetter, dry areas to get drier | NOAA
"The twenty-first century may bring the United States more of the weather it's already got, whether wet or dry. The U.S. National Climate Assessment, issued in May 2014, examined multiple model projections of seasonal precipitation over the rest of this century. In general, precipitation is projected to increase in the northernmost parts of the country, and decrease in the southwestern United States. These maps show projected seasonal precipitation changes for the final decades of this century (2071-2099) compared to the end of the last century (1970-1999) depending on two possible scenarios for greenhouse gas emissions. One scenario assumes that greenhouse gas emissions peak sometime between 2010 and 2020 and rapidly decline afterwards. The other scenario assumes that greenhouse gas emissions continue increasing throughout the 21st century." - Todd Hoff from Bookmarklet

California on pace for hottest year ever |
"LOS ANGELES — This past month was the third-warmest October in California since officials began keeping records more than a century ago, continuing the state’s pattern in what is likely to be its hottest year ever, according to government climatologists. The average temperature statewide last month was 64.5 degrees, less than one degree under the all-time record set in 2003, the National Climatic Data Center reported. In the larger view, 2014 remains on pace to be California’s warmest year with an average temperature through October that is 1.6 degrees above the previous hottest years — 2003 and 1992 — when the average through October was 62.2 degrees." - Todd Hoff from Bookmarklet

"Over the 34 years since then, Sugihara has used his illusion machine to create and build more than 100 illusions: impossible objects such as a solid model of Escher’s staircase, and intuition-defying motions such as balls rolling uphill. “Sugihara has come up with systematic ways of playing with what happens when the rules of the vision system fall apart,” said Arthur Shapiro, a neuroscientist at American University in Washington, D.C. Part scientist and part artist, his work is helping to elucidate the basic mathematics underlying how our brains construct our world." - Todd Hoff from Bookmarklet

Just good business - ‘Cartell’ Chat Room Traders Boasted of Whacking FX Market - Bloomberg
"In an early morning chat, three senior currency traders at some of the world’s biggest banks weighed the pros and cons of admitting a fourth member to their private instant-message group. The traders -- from Citigroup Inc. (C), JPMorgan Chase & Co. and UBS AG (UBSN) -- had worked together for years to manipulate the $5.3 trillion-a-day currency market by sharing details of client orders and coordinating trading strategies, two people with knowledge of a global investigation into the foreign-exchange market said last year. While adding a new recruit would bolster their strength, they worried he couldn’t be trusted to put the group’s interests ahead of his firm’s. “Will he tell the rest of desk stuff,” Richard Usher, JPMorgan’s chief London-based dealer, wrote in the chat published yesterday by the U.S. Commodity Futures Trading Commission. “Or god forbid his nyk,” he said, referring to the New York trading desk." - Todd Hoff from Bookmarklet

Radical new economic system will emerge from collapse of capitalism
"No one in their wildest imagination, including economists and business people, ever imagined the possibility of a technology revolution so extreme in its productivity that it could actually reduce marginal costs to near zero, making products nearly free, abundant and absolutely no longer subject to market forces" - Todd Hoff from Bookmarklet
The point about this being the biggest change since the industrial revolution is a good one. And where we have experienced the change, in music, there's still no resolution. - Todd Hoff
in as much as most musicians can no longer make a living doing music... - Big Joe Silence
Correct. Though have they ever? - Todd Hoff
At this pong the disruption economy like Uber is a race to bottom for wages with the CEO making much money (at least to begin) - WarLord
yes, we did. many of us. now even many long-time professionals are struggling. - Big Joe Silence
Yep, this is the problem, WarLord - Todd Hoff
Big Joe Silence, What's different now? - Todd Hoff
a combination of things. predatory practices in the business side of things is a big part. publishers and labels and agents/promoters and content delivery middlemen, etc... getting some or all of your merchandise profits snatched away from you is a huge problem, since that's what many artists live on now. do you really want me to write a paper on this for you? we no longer get paid even what's agreed upon in contracts anymore. - Big Joe Silence
Yes, a paper would be a great. I think it would help people really understand what's going on. Though I'm guessing you weren't serious about that. I always thought labels stole, er, got most of the money? How can they take the merch deals? The dream was artists could remove the middlepersons and make money directly from their fans. It seems aggregators are hard to kill. - Todd Hoff
i was joking about writing a paper. duplicated effort, as this has been covered plenty by others over the past 15 years. major labels are on the way out, yes. as for DIY, doing that profitably takes capital that most musicians don't have unless they've already been at it as a successful business for at least 5-7 years. but the fact is even the venues demand a huge cut of merch profits, which is making it difficult to pay the bills, much less make any money. - Big Joe Silence
as for the aggregators, they've increasingly found themselves in a position of power and are abusing it. you can't really sell downloadable music without going through one or more of them and they tack on all kinds of contractual conditions/clauses and fees for the pleasure of letting them take an additional cut when you sell units. i don't remember physical distribution being this abusive back in the 80s or 90s. - Big Joe Silence
I don't really know anything about this, but to be on spotify and other services you can't go directly to them? - Todd Hoff - Taylor Swift Is the Music Industry. Interesting. She had the only album to sell more than a million records. “For a digital download, Taylor Swift will probably take home 50 percent of retail,” says Alice Enders, a London-based music industry analyst. “So that’s 50¢ or 60¢, a lot of money compared to a fraction of a penny,” she says. - Todd Hoff

Gut–brain link grabs neuroscientists : Nature News & Comment
"Companies selling ‘probiotic’ foods have long claimed that cultivating the right gut bacteria can benefit mental well-being, but neuroscientists have generally been sceptical. Now there is hard evidence linking conditions such as autism and depression to the gut’s microbial residents, known as the microbiome. And neuroscientists are taking notice — not just of the clinical implications but also of what the link could mean for experimental design." - Todd Hoff from Bookmarklet

artificial intelligence is a tool, not a threat - Rethink Robotics
"Recently there has been a spate of articles in the mainstream press, and a spate of high profile people who are in tech but not AI, speculating about the dangers of malevolent AI being developed, and how we should be worried about that possibility. I say relax. Chill.  This all comes from some fundamental misunderstandings of the nature of the undeniable progress that is being made in AI, and from a misunderstanding of how far we really are from having volitional or intentional artificially intelligent beings, whether they be deeply benevolent or malevolent." - Todd Hoff from Bookmarklet

High-fat diet postpones brain aging in mice | KurzweilAI -
High-fat diet postpones brain aging in mice | KurzweilAI
"A new Danish-led research suggests that signs of brain aging can be postponed in mice if they are placed on a high-fat diet. The finding may one day allow for developing treatments for children suffering from premature aging and patients with Alzheimer’s and Parkinson’s disease. The new research project, headed by the Center for Healthy Aging, University of Copenhagen, and the National Institute of Health, studied mice having a defect in their DNA repair system, resulting in a Cockayne syndrome. Putting the mice on a high-fat diet postponed aging processes such as impaired hearing and weight loss. In humans, this defect causes patients to prematurely age as children and die at an age of 10–2 years." - Todd Hoff from Bookmarklet

Consciousness is integrated information. - Todd Hoff from Bookmarklet
It's amazing any iphone app works at all.. What a mess. It's pretty clear nobody had embedded system programming experience when they started all this.
Extension by inserting code into a template is just really bad design: - (BOOL) application:( UIApplication *) application didFinishLaunchingWithOptions:( NSDictionary *) launchOptions { self.window = [[ UIWindow alloc] initWithFrame:[[ UIScreen mainScreen] bounds]]; // Override point for customization after application launch - Todd Hoff
Weak / Strong pointers is a crazy responsibility for programmers to handle. It's impossible when using tasks. - Todd Hoff
Chaining initializers is more bad design through excessive coupling: self = [super init]; - Todd Hoff
The lifecycles of when objects are created and when methods are created is implicit. I can't tell by looking when things happen. In other words, the dynamic behaviour of the code is not clear at all. - Todd Hoff
MVC. Love it hate it, put everything in the controller. - Todd Hoff
Generally I'm against making the programmer run a compiler in their head to understand what is actually getting called. So though property seems like a good idea it makes very hard to deduce when reading code what will be called when an assignment happens. - Todd Hoff
Cell reuse by a reuse identifier is kludgy and error prone. Why does it need to own the memory? - Todd Hoff
String based selectors are used all over the place. These are not typed so are large source of run time errors when they shouldn't be. - Todd Hoff
The compiler doesn't check for methods in the interface that aren't implemented? It's a runtime error? Wow. - Todd Hoff
Seems odd to create a view controller and then give controller of the memory to the navigation controller. Seem like unnecessary memory allocs/deallocs. - Todd Hoff
In example code I see the use of static variables inside functions. That's bad style. It's more invisible magic code. - Todd Hoff
You can't test anything like the full functionality in the simulator. Beacon stuff? No. Camera? No. The interfaces should be accessible so someone could at least try to write an advanced simulator. - Todd Hoff
Nice debugging and monitoring tools. Very nice. - Todd Hoff
I'm not sure how it could be done better, but the auto layout constraints are bewildering. Oh my. - Todd Hoff
Using reference counting to manage memory when transition application states to background and active and to handle low memory conditions is highly error prone. - Todd Hoff
Not a fan of adding private class members in an @interface section of the .m file. I reserved judgement of this at first, it sounds good, but in practice I prefer everything to be in one place so I can see how everything relates together at a glance. - Todd Hoff
I wonder if they were able to start over on the watch? I haven't seen the watchkit so I'm not sure how it works. - Todd Hoff
Having to explicitly trigger a table update in the UI's main thread is another example of thread weirdness: dispatch_async(dispatch_get_main_queue(), ^{ [self.tableView reloadData]; });. - Todd Hoff
I'm not sure why you would ever create convenience initializers when you can just create convenience constructors and hide all the initializers? - Todd Hoff
Frameworks. For or against? - Todd Hoff
It takes a dozen lines of code to display an alert. That's crazy. Form validation in general is primitive at best. - Todd Hoff
" NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];if ([mediaType isEqualToString:(NSString*)kUTTypeImage]) {" - a couple things here. Having to cast between different encapsulated string types from different frameworks is both confusing and wasteful. Also, dictionaries are great, but the problem is you never know what's in them. Looked at the doc, how was I to know what's in info? It's a constant in some random header file. Enums are at least discoverable. - Todd Hoff
@selector isn't resolved at compile or link time. It's a runtime error. No bueno. - Todd Hoff
Can't test MPMoviePlayerController from the simulator. - Todd Hoff
The complexity around moving the keyboard to not hide form fields is astonishing. Shouldn't that be a feature? - Todd Hoff
Yay, finally got github to integrate with Xcode. Not an obvious setup at all. You have to tell a project to use git, the git repository shouldn't have a readme file or anything in it, you have to use source code control to add a remote repository, then commit while selecting the remote repository. I want down so many blind alleys it's embarrassing. Using git from Xcode is pretty nice. I'm surprised they don't have a revert back to a previous commit command. That's often quite useful. - Todd Hoff
