Cargo cult (which could also be on the inverse side).

Nobody measures anything in this industry -- like the relative RSI or typing speed between the two kinds of keyboards. So people can go around and stick to their personal preferences (even while they could slow them down compared to the other type of keyboard), and insist of their superiority, what actually holds true be damned.
Eight ethical questions about exploring outer space that need answers
The 0 speed reference frame is a usual trick. It's too difficult to do some calculations when the plasma is moving in a direction and the device is moving in another direction.

So you imagine that there is also an imaginary starships moving at a constant velocity in a constant direction. And you put an imaginary scientist doing imaginary measurements from the starship. A more serious name for the "imaginary starship" is "reference frame". All the reference frames that move at a constant speed are equivalent, they have the same laws of physics, so you can choose any of them to make the calculations.

In this case the calculations are more easy if you pick a reference frame that moves with the same speed and some direction that the solar wind (at least locally). It's only a mathematical trick, you imagine that there is an imaginary starship there just to do the calculations.

So if this device really works, it must work when you are measuring it from a imaginary starship that is moving at the same speed of the solar wind. You can't avoid the imagination. Also, all the other reference frames give the same result, but the calculation is much harder.

The advantage of using the reference frame that moves at the same speed of the solar wind is that in that reference frame the speed of the solar wind is 0. It doesn't mean that the particles doesn't move or don't interact, just that they don't move in any preferred direction. So the particles may enter the device from any direction.

If your initial setup is that the device is moving with some speed/direction that is not equal to the speed/direction of the solar wind, then in the reference frame we choose the device is initially moving in some direction with some speed.

Now, when you turn the device on, there is some kinetic energy because the device is moving and there is some energy in the electric field because the capacitor is charged. With the description in the site, the device must work even if it were a static capacitor with a fixed charge. So after a while, the ions around the device change their position and the device may start to move, but there is a maximal speed change. Initially the acceleration may be big, but then it starts to fade away. The initial energy is redistributed, part of the energy in the electric field is transformed in kinetic energy of the device, but there is only a finite amount.

When you see it from the usual reference frame, for example the one that is fixed to the Sun) the calculations are more complicated because now you have to consider the solar wind, and it's difficult to avoid some infinite amounts in the calculation of the energy. But the result must be the same that the result in the other reference frame. The device changes the speed a little and then the acceleration goes to 0.

Wow, you are demonstrating a high level off cognitive dissonance here. I claimed that Kraken was the only place that regular traders could trade a USD-USDT pair. You try to argue I’m wrong by pointing to an exchange that has a USD-TrueUSD pair?

Bittrex does not have a USD-USDT pair available for regular traders. They are literally just testing this service this week with a limited pool of users.

Here’s what they are said in what is the most recent post on their news blog, May 31, 2018:

>During this first phase, fiat trading will be limited to approved corporate customers in the United States located in Washington State, California, New York and Montana. Qualified international customers may participate in the market as well. Like all customers who want to be active on Bittrex, fiat customers will be required to submit to both the standard registration process --including proof that they are operating in qualified U.S. or international regions -- as well as other specific fiat terms and conditions.

Jessica's 2001 (wow!) book "Founder's at Work"[1] is something everyone should read.

The stories behind lots of theses names everyone has heard are amazing. I still remember reading it in about 2006 and being so immediately impressed with everything Paul Buchheit said. It was shocking to me, because I'd started that chapter thinking he shouldn't be in the book ("Gmail? He's not a founder!").

The other thing was the superficial "insights" that one particular (well known) founder had in the book. They were clearly wrong, and they have colored my thinking about luck and being in the right place ever since. It's only recently I've started rethinking that after they made some good (lucky?) investments over the last few years.

I was lucky enough to bag one of these on eBay 10 years ago, someone was selling a god awful computer and I asked if I could just take the keyboard for a vintage computing project. Cost me 10 pounds. I bolt modded it, but eventually sold it as I wanted to fund my HHKB addiction which is a solid keyboard, just more portable than a Model M

Thankfully, a friend gave me another Model M recently, and it's now awaiting a clean and a cable
A lot of that depends on scale too. I was mostly talking about the ability to standardize configuration so that you could replicate your infrastructure on multiple providers. Essentially just making sure that you have a backup plan/redundancy in case something happens and you find yourself needing to spin things up elsewhere on short notice.

You're absolutely right that running them at the same time, data syncing, traffic flow, etc is much more complicated.

I think that misinterprets the term "surprise" in the paradox.

"Surprise" isn't meant primarily as "the prisoner will feel surprised" (though the ending is more pithy if it is put that way), but rather "the event will not be logically predictable for the prisoner".
If that were true, it sounds like an evolution accelerant.

Jokes aside, evolution is not necessarily modern civilization, technology, and laws. Those are our creations, and psychedelics have been an active part of our arrival at them. Psychedelics have been used by humans the world over for far longer than people have been making LSD in labs.
I ended up taking a gamble on a keyboard with Topre hybrid switches, without having tried one first. I actually really like it.

The keys are quieter than mechanical switches (they make more of a soft ‘thunk’ than a ‘clack’). Typing speed and accuracy are quite good. I only use it for work, though, so I have no idea how well or poorly it would perform for gaming or other tasks.

If you don't like those "yellowish" keys, get some peroxide cream, put a layer over all yellowish surfaces and leave it on the sun for a few days, applying more cream if needed. You'll get them back to normal ;-) I've recently "resurrected" my old Creative Prodikeys that way. Applies to any older yellowish plastic stuff, e.g. you want your retro Amiga 500 to look good again etc.

I effortlessly type faster and more accurately on a model M than on my laptop. I actually feel more prone to RSI on the laptop. The laptop keyboard has a flat profile so your fingers have to reach further for the non-home-row keys. The keys are less defined on the laptop and are much easier to press down accidentally, and it's somewhat harder to tell when you've pressed one, so I find that I can't relax my fingers on the home row as much as on the model M. Despite the keys being easier to press down, I feel like I have to keep my hands more tense on the laptop keys. So, ymmv.
I agree that the leap of faith is the most common way people choose to live. But you seem to be describing it from a perspective of somebody who’s never asked themselves the question, or who gave up trying to answer it.

To properly arrive at the leap of faith, you need to first accept that there are no universal truths. Then you can choose some axioms to base meaning on, and build outwards from there. I don’t believe that this approach is truly that orthodox, even if it may arrive at a similar destination to not asking the question to begin with.

There is no universal truth anywhere in life. Even empiricism is based on our subjective experiences, and rationalism is also flawed in exactly the same way. Life itself doesn’t offer any bedrock of truth, but that doesn’t mean truth doesn’t exist. You can take the leap of faith and create your own truth in life.

Your post describes the logical error that the prisoner can claim that "he is surprised" or "he is not surprised" (ie. "extected it"). He cannot, in honesty, claim he wasn't surprised on the first 4 days. He can pretend that he was surprised, sure, and if he could get away with it thereby winning: by all means, all the good to him. But logically, he cannot for certain claim that he isn't surprised" because he cannot dismiss the other possible options. If you follow that logical route, he's only allowed once to claim he's surprised.

> The simple reality is that the judge can only promise you a surprise Monday thru Thursday.

Which means that the execution is on either monday/tuesday/wednesday/thursday but you don't know which one.

That'd result in a 1 in 4 (25%) chance of being right, if he's allowed to vote once. Which day he'd vote on, could be related to how much patience or how nervous he is, how eager he wants to live perhaps?

Is anyone aware of a particularly good explanation of the general confounding issue (not the tank problem specifically) discussesd at the start of the article?

In a talk I'll give in about a month I will be briefly mentioning how confounding between two variables makes much previous research in my field wrong. Most people in my field will never have heard of confounding and I don't have much time to dedicate to this in the talk. Right now I am planning to say something like "If you make two changes at once, you can't know which caused the observed change in the output or the relative contributions of each input change."

I have several of their keyboards and love them. For a while, they were using Chinese copies of Cherry keys and those weren't as good, so I always make sure I get a model with Cherry keys.

My reason for preferring mechanical keyboards is due to spinal nerve damage I have as a result of a dual disk fusion some years ago. I have limited sensation in over half of my fingers and the additional tactile and audio feedback of a mechanical keyboard makes a real difference. I tried one of the current MacBooks in the Apple store and it was awful. There is far too little feedback for my damaged hands. I use my current 2014 MacBook with an external Das Keyboard normally, but it is usable when I take it on the road. I'm not convinced that would be the case with the current MacBooks. Not to pick on Apple too much, the standard throwaway mushboards that come with the Dell systems at work are similarly unusable for me.
I wish they (state governments that legalized it) just tell the truth about marijuana.

1. Like most health claims about weed are all unfounded, and most likely placebo.

2. Certain people, like myself, are very sensitive to weed. Weed, even in small doses, make me very nervous. And even the weed that's supposedly good for anxiety--low, or high cbd's?

3. It's too bad so many of us are self medicating just to feel somewhat balaced in this wonderful country?

4. It's too bad Psychiatry haven't accomplished much since they were duped, along with us, with the wonder drugs (heterocyclic drugs like Proxac) of the ninties.

I know so many people self-medicating, usually with weed, and alcohol.

As bad as alcohol is on the body, it does hit so many receptor sites in the brain. And if we legalized benzodiazepines, maybe we could save many from becoming alcoholics? The argument goes on?

At this point, I would like to see all drugs, except antibiotics, legal.

> it needs to be contextualized

Contextualization can and should occur not just by need, as in where are we going with this, but also

* Where did this come from
* How hard was it to get there
* When was it discovered
* How was it discovered
* When was it accepted

Often times areas of Mathematics or Physics are presented in way that is completely disjoint from their history, that these n-pages of results actually took 50+ years are more to discover and argue over. That careers diverged and were ended over who was on what side.

Too many concepts are communicated as a series of steps, do A, do B, do C ... but you have no idea that you are actually baking a cake. If it isn't a surprise, tell the other party the destination.
Bill to End Patent Office Validity Challenges Introduced in House
I don't understand why so many people are in love with the Model M. I used one for nearly 3 years before switching to a Cherry MX blue keyboard.

After using a modern mechanical keyboard, I would never switch back to a Model M. Probably because of time, on the Model M every key has a different feeling. You never know where the activation point of the key is, because it is a little bit different for every key. The same is for the feedback the keys give you when pressing them down: those old springs just don't give you that reliable feeling the Cherry MX Blue keys give you.
People posting alternative solutions probably haven't watched a dog run through a forest. One of my favorite parts of camping is taking a short hike, while the dogs take a long run all around me (BC and a Britney).

Dogs will run through gaps drones couldn't dream of, and go through underbrush where a drone simply couldn't go. They can carry a much larger payload, longer. The distribution pattern will probably be more random, which is appropriate for a natural environment.

Versus human power? I know some people who could probably knock out 30km in a day, over very rough terrain, at altitude. Only one or two, though. I doubt they could do it every day, or even a few times a week.

It would be hard to scale, though. While I think I might enjoy attempting to teach hundreds of BCs to go on a hike with me, I'm not sure it's practical.
This reminds me of the trains CrossCountry use in the U.K. (as well as a few other names, East Coast Mainline too maybe?).

They have the air con intake next to the toilet ventilation, so the whole train just smells like a toilet. They are kept clean enough, but it’s got that combination of strong cleaning products and a slight background hint of something else that is very reminiscent of public toilets. Throughout the whole train.
tl;dr Congress is apparently trying to pass a law that makes it impossible to challenge patents, and opens the door for an ever escalating abuse of invalid patents sneaking into the system.
I disagree. Rather than have the Brazilian government use coercion and 'haul them out' it is better to let those within that community know there is a way out and offer help to those who want to get out. It's clear many within that community don't agree with this already (like the parents who committed suicide rather than kill their children) and if they could know they could escape that would preferable than forcing views on to other people.

What if our views change about this in the future? Then should they be forced to kill their children even though they don't want to? I know that sounds insane but this happens. There's the classic example of when British colonialists were horrified that homosexuality was not considered a crime in India and they introduced a new law. Well here in the UK that view has completely changed but India still has the law (although it's not enforced), now should we go and tell them they're bad again and force them to change it back? No, they need to understand for themselves and do it themselves. Interference in this way is not a good idea, it just builds resentment. This is true for any argument, rather than force people to do it your way, let them realize on their own why your way is the better way.

Also I don't see why them not being able survive in modern warfare matters. Canada wouldn't survive in modern warfare against the USA but that doesn't mean the Canadians be hauled out. ISIS could be destroyed today by nuking the towns they are in but that would kill innocent people too. If you think coercion is wrong why not apply it consistently. Remember also that if you want them to stop killing their disabled children then someone will have to pay for them, probably Brazilian tax payers, are they willing to do that, also that starts a whole other debate about aborting of disabled children too, this is a hugely complex issue and hauling anyone out to impose one view I think is not necessarily the best way. I would advocate providing support to those who want out of the tribe.

>I don't want to remember more of what I read; I want to have access to a breadth and depth of ideas I can justify with evidence.

That's bad, because without remembering you don't have the ability to quickly know where to look for those ideas and how to evaluate them. Nor do you know how to justify them with evidence (because that depends on remembering domain knowledge of evaluating, classifying and using the evidence itself).

Even if we assumed that you kept a working memory of "first principles" of every knowledge domain you're interested in, and only cared to search and evaluate ideas on demand, you'd still be at a disadvantage to anybody who remembered not just first principles but also higher level information about the knowledge domain -- and thus could skim through tons of BS or bad ideas and sources of information and quickly pick and evaluate only what's relevant.
What does it Take to win an Olympic medal
Assuming the prisoner may only pick certainty of surprise once it seems the prisoner would need a trusted third party such as a notary to write down their solution of choice. Else, they can just reply "wrong, its next day, muwahaha" unless they picked Friday (in which case, the judge was wrong).

If the prisoner is allowed to pick a day every day, they'd pick the next day each time and win.
No, "exponentially faster" means exponentially faster with exponentially more hardware. Specifically, N processors can solve a problem of size N in O(log N) wall clock time, where the previous (serial) algorithm used O(N) wall clock time. Most programmers would say "more scalable" or "more parallel" rather than "faster", but the terminology makes sense and is standard in the context of the PRAM model of parallel computation.

I'm not sure, but I doubt this algorithm is "faster" than the previous one on a single processor.

It's not clarity or correctness but how it is said.

See page 2 of the paper (page 5 of the PDF) for example. That is where he is talking about people being stuck in the 17th century and "how sloppy their proofs are" [1]. I am not arguing that this might not be true! - I argue that it is not helpful to approach introducing and advertising the idea in this way. I'm not a mathematician but I'd understand if someone reacted with defiance to wording like this.
