Two Veterans Debate Trump and his beliefs. Wowser.

bareboards2 says...

@Mordhaus, yeah, good points. Thanks for the clarification of what lies behind the soundbite (nobody has time to explain what they really mean these days, do they?)

However (isn't there always a "however"), I don't agree with "valid to question the integrity of the second vet." Integrity? Pretty loaded word.

It presumes that someone can be gungho about something in the abstract but when confronted with the reality, can't learn something about the world and themselves they didn't know before.

You're right that he didn't know he was CO before. He learned he was.

It isn't integrity to turn away from a learning situation. To me, it is the utmost in integrity.
There are different types of bravery. The bravery to go into battle. And the bravery to decide in the closeknit world of "band of brothers" that you can't be in that particular band anymore.

Maybe it was cowardice in the face of death or maiming that he learned and he ran away. I would say, in this particular case, he honestly came to a new understanding. Otherwise he wouldn't be speaking up, right? He'd be hiding at home? Knowing what soldiers who stayed are saying about him?

War is hell. So many casualties, both physical and mental.

CGP Grey - You Are Two (Brains)

Chairman_woo says...

There is actually an argument that our brains are three due to the way the frontal cortex works. (not the "triune brain" which is a different idea)

The frontal part can exercise control over the two hemispheres and is about as close as we have gotten to identifying where free will comes from. Certainly, in people who have had frontal brain damage there appears to be a direct link to lack of impulse control.
Almost every serial killer in history appears to have had some manner of frontal brain trauma at some stage in their lives and the link to delinquency is fairly well documented by this stage.

The latest research suggests consciousness itself is a fractal programme running co-operatively across the brain, but it remains pretty obscure none the less. The frontal cortex is split between left and right hemispheres, but it certain appears to behave as one in healthy brains.

The best way I could describe it is that the left and right represent the animistic unconsidered side of our behaviour and desires as we see in most animals (interacting via the corpus callosum that connects them). With the frontal cortex seeming to represent the higher functions that allow us to harness the rest of our brain in more considered and abstract ways (presumably also split into left and right).

I think of it like the foreman directing the other divisions of the factory but staying largely hands off when considered decisions don't need to be made.

All of the above is a gross oversimplification though. We can guess at the basis for free will, but it remains elusive.

P vs NP - The most important problem in Computer Science

MilkmanDan says...

I remember studying algorithm time complexities, where ideally the time complexity of an algorithm is a polynomial function -- like O(n)=n^2, or even O(n)=n^100. Most things that seem really hard at first are exponential, O(n)=2^n or whatever. *IF* somebody gets a brilliant stroke of inspiration, those exponential time complexity algorithms sometimes get tweaked to become logarithmic, like O(n)=log(n).

But almost never does a problem that seems really hard at first (exponential) get some brilliant solution that makes it jump into easy (polynomial).

I think we get so caught up in the abstract concepts and semantics that we tend to overlook what seems like common sense: some problems are simply harder than others, with no "magic bullet" solution. So, I think that P is almost certainly NOT equal to NP. But that quote around the 10 minute mark puts that in a pretty eloquent way that is easy to understand even to the layman -- a trait which is entirely too uncommon in academia.

BUT, I must admit that the few occasions when I studied an algorithm that seemed like it obviously couldn't get any better than exponential time complexity, only to be shown a brilliant outside-the-box solution that brought it down to logarithmic time complexity definitely taught me some humility. So, you never know.

Doom WASN'T 3D! - Digressing and Sidequesting

Jinx says...

I guess its a really long winded way of saying "these games don't have a z coordinate".

but yah, its all abstraction and illusion. Maybe in the future somebody will make a holovid about how the games of the early 21st didn't have lightning or shadows because they weren't ray-traced or something.

vil said:

Oh come on. Fairly informative and correct for the most part except for the title and main argument. Still, it is about Doom and binary partitions, so thats all OK.

Anything on a flat monitor is "just faking" 3D.

Yes, Doom levels could still be designed in plan view, but the in-game display of the floors, walls and ceilings is a very rudimentary, but definitely 3D, experience. Displayed objects have an obvious X, Y and Z coordinate. The Z coordinate was not used for aim (people had not got used to using a mouse for aim at that point) but it was used for display and movement.

Also forgot to complain about flat sprite monsters.

No Doom was not "computed like any other 2D game", or rather it partly was, but then on top of that it was displayed in 3D, which was a big deal back then. Yes, fake 3D, on a monitor, but definitely 3D.

Quake ran in plain VGA so the argument about 3D accelerators falls rather flat :-)

The Game Boy, a hardware autopsy - Part 1: the CPU

vil says...

Z80 FTW!

Machine code is by definition perfectly understandable, just RTFM. Even machines understand machine code. Every other kind of program is just abstract gobbledygook with random syntax until compiled or interpreted.

Big Think: John Cleese on Being Offended

enoch says...

@Imagoamin

i can agree with your basic premise:free speech can have consequences in the form of MORE speech.

you are totally free to espouse the most ridiculous,self-centered narcissistic cry-baby drivel you like,and i am totally free to ridicule you as the cry-baby bed-wetter you are behaving like.

the problems arise when that interaction is then seen as "harassment" and a defamation of the constantly oppressed group of bed-wetters.how dare i slander such a tender group! havent they suffered enough?

nobody is saying that one group is excused from free speech or from criticism,and most people would agree that if you yell FIRE in a room and cause a panic when there was no fire,there should be consequences for your actions.

what people ARE saying is that making certain words unacceptable,therefore changing the very language we use to express,convey and deliver complex thoughts,feelings and imaginings is counter-productive.made further so when an abstract art form such as comedy is so easily taken out of context to further an agenda.

remember #cancelcolbert?

the comedy and satire was totally lost on that over-privileged nitwit suey park.she instead focused on a single element of his monologue and chose to be offended,without even considering the larger implications of the humor in colberts bit.

does she have a right to be offended?of course.
does she have a right to be outraged and start a twitter campaign to shut down colberts show?yep..she sure does.

and we have the right to absolutely take her inane,and un-self-aware false campaign for justice to task,and ridicule her relentlessly.

because bad ideas,poor understandings and judgements dressed up as social justice SHOULD be ridiculed for the stupidity they represent.

as for your assertion that comedians are thin skinned,or need to grow a thicker skin,i think you have no idea what you are fucking talking about.you ever spoke in public? in front of crowd?

believe me...you grow thick skin,and fast,until it becomes titanium.

i see no further reason to beat that particular horse but just look up chris rock,seinfeld,louis ck ,bill burr,joe rogan.they all lay out quite clearly why universities are a dead zone for comedy.

because the extreme end of social justice warriors are humorless cunts.

chris hedges-brilliant speech on what is religion?

shagen454 says...

It almost sounds like he is suggesting to keep an open mind and learn about other cultures, religions & mythology in order to understand those perspectives; and overall to be humble to the mystery: that we do not know.

In my opinion some of his opinions were a little contradictory - he doesn't believe in any sort of god or gods, but it seems that a wiser statement would be that he doesn't know, which would correspond with the "I don't believe in atheists" theme.

Furthermore, I honestly don't think that those who (in Hedges' words), "do not explore the religious impulse" are inhuman. Even if someone never explores it in their lifetime. In my opinion - the late bloomers who have disconnected themselves from all inclination of organized religion or spirituality, to find it on their own later in life might have a few more advantages than those that did not disconnect themselves from it at some point.

My personal preference is that I do believe in god because I want to believe in god. Whether it's a metaphor, completely abstract energy, a point in spacetime, a massive intelligent energy field that existed long before the big-bang, a life-force found only on Earth or the Milky Way or a fucking super mega alien technological consciousness program experiment or even a microscopic white dude flying on a microscopic magic carpet or all of the above and none of the above. I just believe even though my version of whatever creation/god is, is completely unidentifiable, it's everything and it's nothing.

pundits refuse to call oregon militia terrorists

VoodooV says...

Sadly, it really doesn't matter what they call them, because the term terrorist has become meaningless. I've said this all the way back when GWB "declared war on vague abstract concept"

The definition stated earlier is not wrong, but you can use that term for just about anything. Americans were terrorists against the British when we revolted. We also had the audacity to not march shoulder to shoulder against the Brits as was the standard for every "civilized" army back then.

The only difference is who wins and who loses. if you win, you're a revolutionary. if you lose, you're a terrorist. and if you're white, you're a militia group.

This was a calculated move by the terrorists though. I think they deliberately picked some piece of shit building of no value that no one cared about and was unused, made sure they didn't kill anyone but yet still forcibly occupied it with weapons. It's a dare...it's an attempt to goad. They want the feds or police to go in guns blazing. They want suicide by cop because it will ultimately benefit them and gain sympathy for them. They took something that is completely inconsequential other than it was owned by "the gub'mint"

The Fox pundit thinks they're peaceful? armed occupation is peaceful now? Just because they haven't physically hurt anyone doesn't make them peaceful. They stopped being peaceful the instant they picked up their weapons.

Love all the usual buzzwords and sound bites from the fox pundit without any actual specifics. Once again, who specifically is this "left wing media?" They never actually say who. more accusations of "big gov't" without any specifics. They keep talking about these intrusions into our lives, but yet, can't seem to name them.

All fear, no concrete issues. Standard geriatric (that means old, bob) Fox audience.

I Could Do That | The Art Assignment

robbersdog49 says...

Hmmmm. I buy some of that, but not all of it. Or rather it's true in some cases but not all. Some art, like the two lovers/clocks has meaning beyond it's own form and that's important to appreciate it. But there are certainly some abstract works out there that are just too lost in art.

I'm on the edge of the art world as an illustrator and photographer and completely get the 'go do it' angle though. Just saying 'I could do that' is missing the point entirely. Anyone who looks at a simple bit of art with a high value and thinks it must be simple to just paint a few squares and put a thousand pound price on it can't honestly believe it, otherwise we'd be up to our eyeballs in shitty paintings with huge price tags.

If a bit of artwork needs an artist's name to be worth something then consider what it took for the artist to get to that place. They didn't just wake up one morning a famous artist. The name gives context and can be important. Not every time, some 'artists' are just way too into their circlejerks and mutual bigging up that the only skill an artist might need is to be just weird enough and in the right place at the right time to be one of the 'in crowd', but to be fair this isn't the case with the vast majority of abstract art.

I Could Do That | The Art Assignment

Jinx says...

Yah well, I can see faces in my cork flooring is I search hard enough. I'm fine with art that only works well in context, like the clocks, but simple abstract scribbles or an entire canvass painted one shade of blue...yeah I'm going to put about as much effort searching for meaning in that as the "artist" did in conceiving it. Sorry, I'm a philistine.

Don't Stay In School

Asmo says...

The concept that you can go to university and learn how to cut people open and fix their heart = you do not need abstract concepts in high school... Dissecting a frog doesn't prepare you for putting it all back in working order.

The things I've learned since I left school 22 years ago dwarf the knowledge I learned at high school and have since discarded.

Core skills like literacy and numeracy, of course, but you shouldn't be doing complex maths when there are many more practical things you could be doing.

eg. The local high schools now offer MSCE and Cisco certified courses in high school as an elective. So you can study in year 11/12 and come out of high school fully papered up for a career in IT rather than doing it once you leave.

I also fully support the right for kids to drop out of school to start apprenticeships at 14-15 so that they have established a trade by the time they are at the same age as graduates. Why waste the extra 3 years doing classes that will almost certainly not assist you in any way, shape or form, when you can be working full time learning a trade and earning a wage (albeit not a great one, but you don't get paid to sit in class either ; ).

Jinx said:

Nobody knows that want to be an x or y when they are 11. It's easy to look back in hindsight and say "I never needed to know quadratics", but maths is absolutely critical to a vast number of academic areas and skilled trades. How do you give everybody the opportunity to become, idk, an engineer, without a lot of what you teach becoming more or less useless to most others. It has to be a broad curriculum which narrows as you progress because either you have to allow kids to make decisions about their futures for which they really lack the experience or knowledge to make, or you are allowing schools to effectively close off career paths for their students which is fucking dystopian because they'll just do whatever maximises their success rates.

For the things Dave wishes he was taught...well some of them are actually offered as subjects in some schools e.g. Economics. For the others, well, I work in Adult Education and we do actually do a lot of the things school misses. For example, we have courses for single parents (particularly young/teenage mums) on how to budget effectively etc, all funded 100% by the tax payer. It's an area that actually survived the latest budget and that we've been asked by Ofsted to expand, so, you know, it's not completely ignored, its just not really delivered by schools.

Is reality real? Call of Duty May Have the Answer

Chairman_woo says...

I'll keep this fairly brief for once but, why is everyone so hung up on the idea that the theoretical "simulation" is somehow distinct from "reality"?

To put it another way, what are the laws of physics themselves?

We do appear to inhabit a reality defined by laws we can describe mathematically. The mathematical models may be abstracted, but whatever they describe is presumably in some sense analogous in its "true" nature right? (even if we can't get at it directly)

If you take the leap into thinking that reality may be more mathematical than physical in nature (or rather that "physical" is a property of what we could think of as mathematical phenomena interacting in the right way), then questions about who's computer were in kind of become moot.

If reality itself is fundamentally mathematical in nature, we don't need a computer in which to run it, so much as reality itself is the computer.

I really don't think it's an either or thing, more like a shift in how we think about the concept of "reality" itself. Even if an experiment could prove that the universe is holographic in nature, it needn't change anything about it's validity as a "real" thing.

The "simulation" and "reality" needn't be mutually exclusive, merely different ways of understanding the same phenomenon i.e. that we exist and experience things.

Is Climate Change Just A Lot Of Hot Air?

bcglorf says...

@newtboy,

How about great big citation needed. Your making a lot of assertions and about zero references to back anything, your just one step shy of claiming because I say so as your proof.

The rotting material creates exponentially more methane than any mechanism could trap.
Citation required.

your study quote did not say that "they've identified regions up north where the soil absorbs more methane the warmer it gets
The abstract is only a paragraph and the charliem gave the link up thread, just go and read it already, they did numerical estimates AFTER going in and directly measuring the actual affects. And I must additionally add, it's not MY link but was instead the ONLY claimed evidence in thread of your catastrophic methane release.

Let me start us off, the IPCC once again summarizes your problem as follows:
However modelling studies and expert judgment indicate that CH4 and CO2 emissions will increase under Arctic warming, and that they will provide a positive climate feedback. Over centuries, this feedback will be moderate: of a magnitude similar to other climate–terrestrial ecosystem feedbacks
http://www.ipcc.ch/pdf/assessment-report/ar5/wg1/WG1AR5_Chapter06_FINAL.pdf
From FAQ 6.1

There are caveats prior to the above quote about unknowns and uncertainty and the possibility the affects will be less or more, but the consensus is, don't panic. Like I said.

As for bringing that person from 1915 in today, you don't get to tell them the environment will be destroyed 100 years from 2015 in the year 2100 as a result. You have to prove that first, which you have merely asserted, not proven. On the other hand, my evidence was bringing our visitor from the past showing them the year 2015, and the consequences of rising global temperatures by 0.8C since his time in 1915. Then I say we ask him if abandoning coal power, airplanes, satellites, and cars to prevent that warming is a better alternate future he should go back and sell the people of 1915 on. I'm thinking that's gonna be a hard sell. I'm additionally pointing out that the IPCC projections for the next 100 years is 1.5C warmer than today, so we'll be going up by 1.5 instead of the 0.8 our visitor from the past had to choose. The trick is, I don't see how you can claim that panic should be the natural and clear response. You need a lot more evidence, which as stated above you've failed to provide, and more over what you've posited is contrary to the science as presented by researchers like those at the IPCC.

It may be unfishable in 15-20 years at current acidification rates.
citation needed.

by 2025 it's estimated that 2/3 of people worldwide will live in a water shortage.
citation needed, and you need to tie it to human CO2 and not human guns and violence creating the misery.

Northern India/Southern China is nearly 100% dependent on glacial melt water, glaciers that have lost 50% in the last decade
citation needed

The downvote was not for your opinion, it was for your dangerously mistaken estimations and conclusions...
, says you. If you don't use any evidence to refute me it's still called your opinion...

Jon Stewart on Charleston Terrorist Attack

scheherazade says...

Terrorist attacks are more multifaceted.

First, they are an opportunity to generate work for the defense industry.

Second, they are usually for a reason. Often some angst over our own actions in foreign countries. For example, the news says AQ is a bunch of crazies that hate freedom, however AQs demands prior to 9/11 were to get our military out of the holyland. While that's not an offense that deserves blowing up buildings, it is definitely not the same as some banal excuse like hating freedom.

Thirdly, they are often perpetrated by some persons/groups that we had a hand in creating. We install the mujahedin in Afghanistan, knowing full well what they'll do to women, and then use their treatment of women as one excuse to later invade. Saddam worked for us, was egged on to fight Iran, was egged on to suppress insurgents (the 'own people he gassed'), and we later used his actions as one excuse to invade.

At the time, the mujaheddin was useful for fighting Russia as a proxy. At the time, Saddam was useful for perpetuating a war where we sold arms to both sides. Afterwards, they were useful for scaremongering so we could perpetuate war when otherwise things got too quiet and folks would ask about why we're spending big $$$ on defense.. (In the mean time hand-waving the much more direct 9/11 Saudi connection).

... Plus if on the off chance things do 'settle down' in areas we invade, that creates new markets for US companies to peddle their wares. You can reopen the Khyber pass for western land trade with Asia, you can build an oil pipeline, and you can prevent a euro based oil exchange from opening in the middle east. All things that benefit our industry.

So in practice, as far as big industry is concerned, there's a utility in 'fighting terrorism' (and perpetuating terrorism) that just doesn't exist with internal shootings. As such, unless another 'evil empire' shows up, the terrorism cow is gonna get milked for the foreseeable future.

Sure, there's a rhetoric about preventing terrorism, but our actions do nothing to that effect. It's just a statement that's useful in manufacturing consent.

There's a particular irony, though. That is, that while such behavior is 'not very nice' (to put it mildly), it does however provide for our security by keeping our armed forces exercised, prepared, and up to date - such that if a real threat were to emerge, our military would be ready at that time. While that seems unlikely, when you look back in history at previous major conflicts, most were precipitated rather quickly, on the order of months (it takes many years to design and build equipment for a military, and the first ~half a year of any major war has been fought with what was on hand). So in a round-about, rather evolutionary way, perpetuating threats actually does make us safer as a whole.

To clarify the word 'evolutionary' : Take 10 microbes. All 10 have no militant nature. None are made for combat. It only takes 1 to mutate and become belligerent in order to erase all the others from existence. If some others also mutate to be combative, they will survive. The non combative are lost, their reproductive lines cut off. As there's always a chance to mutate to anything at any time, eventually, there is a combative mutation. So, all life on earth has a militant nature at some layer of abstraction - those that exist are those that successfully resisted some force (or parried the force to its benefit. Like plants that use a plant eater's dung to fertilize the seeds of the eaten fruit).

The relationship holds true at a biological level, interpersonal, societal, national, and international level. Societies that allow the kind of educational and military development that leads to victory, are those that have dominated the planet socially and economically. For example, Europe's centuries of infighting made it resistant to invasions from the Mongols, Caliphates, etc, and ultimately led to the age of colonialism. For the strengths built with infighting, are later leveraged for expansion. As such, the use of "terrorism" to perpetuate conflict, is ultimately an exercise in developing strength that can later be leveraged.

Our national policy is largely developed in think tanks, and those organizations are planning lifetimes ahead. So these kinds of considerations are very relevant.

TL/DR : Yes, agreed, the terrorism thing is B.S. on many levels.
