Why Is There Something Rather Than Nothing? -
Why Is There Something Rather Than Nothing?
"Well, why not? Why expect nothing rather than something? No experiment could support the hypothesis ‘There is nothing’ because any observation obviously implies the existence of an observer. Is there any a priori support for ‘There is nothing’? One might respond with a methodological principle that propels the empty world to the top of the agenda. For instance, many feel that whoever asserts the existence of something has the burden of proof. If an astronomer says there is water at the south pole of the Moon, then it is up to him to provide data in support of the lunar water. If we were not required to have evidence to back our existential claims, then a theorist who fully explained the phenomena with one set of things could gratuitously add an extra entity, say, a pebble outside our light cone. We recoil from such add-ons. To prevent the intrusion of superfluous entities, one might demand that metaphysicians start with the empty world and admit only those entities that have... more... - Todd Hoff from Bookmarklet
[1410.5401] Neural Turing Machines -
"We extend the capabilities of neural networks by coupling them to external memory resources, which they can interact with by attentional processes. The combined system is analogous to a Turing Machine or Von Neumann architecture but is differentiable end-to-end, allowing it to be efficiently trained with gradient descent. Preliminary results demonstrate that Neural Turing Machines can infer simple algorithms such as copying, sorting, and associative recall from input and output examples." - Todd Hoff from Bookmarklet

These self-cooling walls could replace air conditioning
"To break this depressing cycle, architects from the Institute for Advanced Architecture of Catalonia in Barcelona are developing walls that cool themselves without the need for electricity. The technology uses a substance called "hydrogel", which absorbs water and can swell to up to 400 times its original size. When the air around the hydrogel heats up, the water evaporates, which cools the air around the gel by around 5° Celcius. The mechanism’s not dissimilar to the way our body cools itself down by evaporating water from the skin’s surface in the form of sweat.   To create a self-cooling wall, bubbles of the gel are inserted between two ceramic layers." - Todd Hoff from Bookmarklet

A Family Rejects the Industrial Model and Rebuilds Their Farm – The Plate: Maryn McKenna
"The current Will Harris expected to carry on that legacy, and for many years, he did. He went to the University of Georgia, earned an agricultural-science degree, returned to the farm, and put into practice everything he had learned. That meant routine antibiotics, hormone implants and grain feeding for the cattle, and routine fertilizers and pesticides and herbicides for the fields they sometimes browsed on. By his 40s, Will Harris was running two profitable, perfect monocultures—one of meat and the other of grass—and doing everything his education and family history told him he should. And then he stopped, and thought, and changed his mind." - Todd Hoff from Bookmarklet
"On its 3,000 acres, a mix of owned and leased, he and his 110 employees run 10 different species: cattle, pigs, sheep, goats and rabbits; and chickens, turkeys, geese, ducks and guinea hens. Everything is raised out on the restored pastures, which now support a complex mix of grasses. The animals move through the fields in a carefully plotted rotation, each eating their favorite... more... - Todd Hoff

BBC News - The anarchic experimental schools of the 1970s
"Catterall recalls 40 years ago gathering in the centre of Liverpool with a group of children from the free school, all holding a tomato. When you see him, lob it, the teacher told them. The venerable man they were waiting for appeared and the children duly let fly. But the target was not just anyone. It was Edward Heath, the British prime minister. The children have been ordered by their teacher to bombard - albeit with tomatoes - the elected leader of the country. It's hard to imagine a time when teachers would take schoolchildren on a trip to heckle the prime minister - let alone throw things at him. Breen laughs at the absurdity. "It was just another adventure for me. It was a day out. It's not till I got older that I realised what it was about."" - Todd Hoff from Bookmarklet

Baby boomers ruined America: Why blaming millennials is misguided — and annoying - -
Baby boomers ruined America: Why blaming millennials is misguided — and annoying -
"Baby boomers came of age in an era of unprecedented prosperity. They were raised by parents who had survived poverty, war and the true sacrifice of a generation burdened with great moral struggles. As a whole, they experienced economic and physical security. Baby boomers received, by today’s standards, inexpensive and widely available education, preparing them for a thriving and open job market. Success at the beginning created a strong foundation for financial and personal success on a level the world had never known. This led to America’s greatest asset: the middle class. So what did they do with all their good fortune? From the time the baby boomers took over, the United States has experienced an economic environment plagued with unfounded asset and real-estate bubbles and collapses. The bubbles were caused by blind greed on the part of investors, and a blind eye on the part of regulators. The baby boomers forced the financial and banking system out of relative security to high-risk systems." - Todd Hoff from Bookmarklet

Another month, another global heat record broken -
"WASHINGTON (AP) — September brought more record heat globally, and meteorologists say Earth is now on pace to tie for the hottest year ever recorded. The National Oceanic and Atmospheric Administration announced Monday that last month the globe averaged 60.3 degrees Fahrenheit. That was the hottest September in 135 years of record keeping. It was the fourth monthly record set this year, along with May, June and August. The first nine months of 2014 have a global average temperature of 58.72 degrees, tying with 1998 and 2010 for the warmest first nine months on record. While parts of the U.S. Midwest, Russia and central Africa were slightly cool in September, it was especially hotter than normal in the U.S. West, Australia, Europe, northwestern Africa, central South America and parts of Asia." - Todd Hoff from Bookmarklet

Philippe Starck's new prefabricated house realises the modern living ideal
"Standing at the counter of his new prefabricated home - indeed, his actual home - Philippe Starck reminded a small group of visitors that shelter is life's second-most critical necessity after food. That well-worn axiom that necessity births invention: well, we were inside it. The house, a prototype on the outskirts of Paris, is named PATH, for Prefabricated Accessible Technology Homes. And in his mind, it represents the modern living ideal.   This vision had been in development for five years, when he first entered into discussions with Riko, a Slovenian engineering and manufacturing company that specialises in industrial prefabrication and energy production technology. Turns out, it's not so easy to conceive a home that can be delivered in six months and constructed in two weeks." - 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

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

Former NSA director had thousands personally invested in obscure tech firms | Ars Technica
"New financial disclosure documents released this month by the National Security Agency (NSA) show that Keith Alexander, who served as its director from August 2005 until March 2014, had thousands of dollars of investments during his tenure in a handful of technology firms. Each year disclosed has a checked box next to this statement: "Reported financial interests or affiliations are unrelated to assigned or prospective duties, and no conflicts appear to exist." Alexander repeatedly made the public case that the American public is at "greater risk" from a terrorist attack in the wake of the Snowden disclosures. Statements such as those could have a positive impact on the companies he was invested in, which could have eventually helped his personal bottom line. - Todd Hoff from Bookmarklet

"Sugar is the notable exception to “food neophobia,” as researchers call that early innate fear. In utero, a 13-week-old fetus will gulp amniotic fluid more quickly when it contains sugar.

"Using that method, the Griffith University professor Maxime Aubert and his team were able to determine that the Sulawesi paintings are, at minimum, 39,900 years old. Which makes their minimum age at least 2,000 years older than the minimum age of the oldest European cave art. (While the paintings are strikingly similar in content—human hands, animals teetering on stick-like appendages—they are also strikingly different in style. The Indonesian images "look ‘line-y,’ almost like brush strokes," Alistair Pike, the archaeologist who identified what was preciously considered the world’s oldest cave art, in Europe, told Nature. Early European images, on the other hand, "look dabbed, almost like finger paint.")" - Todd Hoff from Bookmarklet
