In my experience, children (and most people) just conceptualize infinity as a very large set, just as they perceive a tire a "circle", and think a square drawn on paper is made up of "lines".

It requires years of thinking about these mathematical entities before people get a first glimpse of what they really mean, beyond a simplistic qualitative experience.

To most people, children included, infinity is conceptually no different from the amount of sand on a beach. They just allow that it is simply not quantifiable. That turns off the brain.

The more interesting thing to test, I would argue, would be the human mind conceptualizing a very, very large but ultimately finite set of something. That requires that we make a distinction between the discreteness of something and our ability to quantify it.

That is a much more difficult concept to comprehend, and it must be understood before we can even begin to think about teaching a child about mathematical entities like infinity, circles, or lines.
Thanks.

The other issue with the links is that the braces keep getting cut off by sites (as happened for your link, need to include that last } for it to work). But having the URL be the save mechanism is just so darn appealing to me.

I generally work around each qubit in an EPR pair appearing to be maximally mixed by conditioning the displays. Add a control to the other wire in the same column as the display, and you'll see the conditional state. Also there's the 2-qubit density matrix display.
Issuing debt is just an accounting trick to maintain credibility of the currency (i.e. That we aren't just printing dollars willy-nilly to fund the government)

The huge chunk of debt is owed from one part of the government to the other.

No one ever cut their way to growth. The key is almost always to grow the GDP faster than you grow the debt on average. The nominal debt number will never go down - ever - but it should stay fixed or shrink relative to GDP if possible.

I'd usually not even consider replying to such a post as you clearly have neither read nor tried to understand my comment.

I replied to a post made above, and expressed deepest sympathy for the Japanese people. While I was born in central Europe, I'd rather not be a citizen of any nation. I spend more time abroad than in the country I was born in. Speaking of which: central Europe currently has a huge resurgence of facist ideologies and xenophobia due to migrants from war-torn countries. Something which is utterly inconceivable to most people able to read a history book, given Europe's not so distant past with genocide. Unfortunately, xenophobia and right-wing sentiment is something that every democracy and thus nation faces, Japan isn't exempt from that [0] [1] [2].

(I currently live in Asia and spend a lot of time in Arabic countries, you may reconsider educating me on the subject with references to the bboy scene.)

> Is DRM required for streaming music? Definitely not.

Technically? No, it isn't required. But it seems pretty necessary if you want to have deals with major labels and publishers. There already exists a musical equivalent of GOG. Bandcamp [0]. Music sales are DRM free, you can choose your file format and quality, and you can stream any artist DRM-free on the website or app. However, you won't find the latest Taylor Swift or Kanye release for sale on Bandcamp or anywhere without DRM.

That is a big "if". A good technical cofounder will identify the latent technical debt that exists in an outsourced prototype and if that number is too high, a rewrite can be justified.

I don't think I can come up with a good definition that I would be perfectly happy with.

I do believe however that everything you experience will to some degree have an impact on you, even if you don't necessarily form memories around them and are able to recall these experiences.

Also especially with grief it seems important to share the emotions we have, so that we can understand our own emotions better and process them. It seems to me that precisely when we achieve that goal of processing grief the lasting impact is going to be less than it would be otherwise. That doesn't make the contributions and experiences that help process that grief any less valuable.

Sufficient storage to handle local load + variation should be pretty well predictable in the future. The interesting difference to me is, since storage will probably cost substantially more than generation, what the ratio will mean for cost of energy in various locations. I have no doubt that at some point, the solar generation + storage formula will be broadly cheaper than fossil fuel.
Can we quit with the Moore's law bullshit? It's not a law! It's just an observation about the direction a graph seems to be moving.

Yeah, we hope processors keep getting more powerful. Calling this "Moore's law" is idiotic. And probably confuses poor journalists and undergrads.
>An article about the past and future of Apple that doesn't mention Jonathan Ive?
Can someone explain this to me. I keep hearing about how big Jonathan Ive is in relation to Apple and I think I've even seen a book that claims he is the genius behind Apple. But from what I see and understand he is mostly a designer who executed on Steve Job's ideas (it's hard to think of the very quirky and exacting design of Apple Products not having some major input from the quirky and exacting Jobs) and I've even read somewhere that his major contribution to the original Ipod (arguably the product most responsible for Apple's comeback) was the white color of the earphones. Are you sure you're not just replacing the cult of Jobs/Cook with the cult of Ives. I genuinely would like to know why a product designer gets so much praise/credit for Apples success since great design is only one of many reasons (and probably not even the most important) for the great products they make
On a related note, we go through great lengths in the Kestrel HTTP server [0] (which also uses libuv) to have fast HTTP parsing. As an example, we attempt to read the method and the HTTP version as longs and compare them to pre-computed longs in order to have fast comparisons and reuse strings containing standard methods and versions (reducing memory allocation is the main driver of our optimizations) [1], so we don't have to allocate those strings on every request. We do a similar thing for headers [2]. We also manage a lot of our own memory, despite using a garbage collected language [3].

> The fundamental problem with the estate tax is that it's a huge tax that happens with semi-unpredictable timing, which induces rich families to do estate tax planning to avoid having liquidity problems when it happens.

Well, yeah, it would be much simpler and more effective if inheritances were just taxed as income to the recipient with provisions allowing them to be split and recognized over several subsequent tax years (e.g., if the total inheritance received in any year is greater than 1/10 the pre-inheritance AGI, the excess can be recognized for tax purposes in subsequent years, with a minimum per year amount equal to the lesser of 1/10 the pre-inheritance AGI in the year received or 1/20 the total amount of the inheritance.)

Moore's law (as it is generally talked about) is actually a pretty good indication of how much computational power we can get from a single processor core.

That, combined with Amdahl's law, means that the unmistakable levelling off that we're seeing now will place some pretty firm limits on what we can compute until we move off of silicon.
Mcclintock aside, nature doesn't vault the spices barrier when recombining. So putting a fish gene into a plant (arguably the earliest use of GMOs in our food) is not something that could be considered "recombined naturally".

Dealing with retirement investment policicies offered in Ireland, I see two sides:

1. Actively managed funds diversified across equitieis, bonds, cash, etc

2. Index funds for specific indices, such as "top 4,000 US companies"

The danger with 2, they say, is you're not diversified. That'll be up to me I suppose to try to diversity into other areas.

Tornado still too low level.

- It's verbose compared to flask.
- It reinvent the wheel, while flask uses great components such as werkzeug.
- If you want to make a component, it's complex.
- It doesn't come battery included for the Web like Django, just the bare minimum.
- It misses the opportunity to provide task queues, RPC or PUB/SUB which are key components to any modern stacks are made easily possible by having persistent connections.
- It ignores async/await potential of unifying threads/process/asyncio and don't allow easy multi-cpu.

Don't get me wrong, I think tornado is a great piece of software, but it's not match against innovative projects we see in Go or NodeJS such as Meteor.
Index funds expose you to essentially the entire market; it's the sum of thousands of tiny pieces of businesses all across America. We're not putting all our eggs in one basket, rather, we're all distributing them across many.

> Users are massively excited about new Android releases

and these people are usually out of touch enthusiast-types who are happy with half-baked releases that require a lot of tweaking, rooting, and replacement launchers and such to be usable. The 5.0 release a year ago was just a nightmare. It was slow and introduced a significant memory leak that I find impossible to believe that Google didn't know about at launch. But Google likes to cheer on its product and have Nexus yearly launches. Tying your physical product to your software one seems a questionable strategy at best, and a boneheaded decision at worst. I'd be happy with a new version every two years with significant refinement done in the meantime.

I have a Nexus and I fear every major update. It just breaks my phone and causes me stress until a .1 or .2 update finally fixes the issues Google introduced. If we're in a position where even Nexus owners are scared of updates, then there's something fundamentally wrong here. Worse, this morally empowers OEMs to say, "Well, google releases unfinished code, so we'll going to skip this update for a while." Honestly, the phone OEMs that went from 4.x to 5.1, skipping 5.0, were on the right side of history here. Every other Google update is half-baked and everyone knows it.

I don't think Google is giving itself enough time to iron out the issues. Slowing down this train is the only solution here that makes sense, imo. Meanwhile my ipad is bulletproof. Sure it gets minor issues now and again, but Apple's QA level is leaps above Android.

Lastly, the mobile revolution, at least in terms of phones, has long matured. Every update is just another denial about how close we are to the innovation grave here. There's just nothing compelling that requires frequent updates. Its time to move into a refinement period, the same way MS took NT4/2000 and made XP/2003 or Apple took a 3-4 year innovation break between Tiger/Leopard and Lion/Mountain Lion.

I wouldn't bet on that. What they're building is a vehicle that conveys things to Mars. If that massive problem is being handled, entities like NASA are free to focus on what they want to put on Mars. If SpaceX is just ferrying NASA's shit, I'd bet we'll see more than trash inside Red Dragon.

Interesting. I've worked with a few designers who had Xcode _installed_, but they were mostly using it for the Simulator. Using IB wasn't something they were comfortable with. I'd be really impressed with somebody who's a Sketch/Photoshop wiz coming over to IB and being productive.

On the flip side why would a non-developer bother to install Xcode and learn IB when they can export their ideas directly from Sketch/Photoshop into clickable "prototypes"?
The risk worries me too. Look at it this way: the whole purpose of a market is to allocate capital to productive ends. If everyone invests in index funds, market capitalization (and thus capital allocation) becomes a function of inertia and ceases to have anything to do with actual performance (because nobody is interested in looking at actual performance). As a result, I'd expect productivity growth to slow.

Guess what? Productivity growth has been slowing.
Maybe that is a function of your market, but indexing doesn't prevent you from becoming diversified.
This is very encouraging to read. I have had a sense of this all along - that which college you attend has very little to do with your intelligence or your capabilities.

> the same kinetic energy as a lake

Not all locations have a lake (or 2) conveniently located near a large elevation drop.

The article says "They move up and down an 8-degree slope with an elevation change of about 3,000 feet", that's a lot of energy.
Above average. Of course those people all made an above average choice in active management.
To be fair, experts in a field that's whole existence is being criticized (e.g. saying modeling isn't accurate/whatever) shouldn't be given more weight in that regard.

Consider how many 'experts' there are in numerology. Should we restrict a person from speaking out against them because he/she isn't an expert?

Desperate hit piece, designed to ignore Apple owns the hardware and the OS, and Google only owns the OS (excluding Nexus devices). Had they compared Nexus/Android and Iphone/IOS adoption rates, I think their would have been a much more clear picture of the situation.

Articles like this always seem to be some awkward attempt at turning a strength (Androids wide adoption, budget friendly alternative phones, etc) into a weakness, via the magic of nuance-free comparison.

Uhh... no they're not "essentially the same." The value of being in the same room as knowledgeable people is interacting with them. If there's something that is unclear or that you want to delve into, you have an interactive way to do so.

This whole "self-learning is just as good!" is ridiculous. If it was, it would already rule the world. People trust accreditation for a reason.
If your goal is to be able to build something without needing a technical cofounder, then definitely, being able to do both sides of the business is invaluable. But if your goal is to focus on the business side and find someone you can trust to lead technology, then I think you're better off spending that learning-to-code time sharpening your business tools.
Perhaps overly generalizing, most everyone's portfolio is a poor approximation of the overall market with extra fees taking away even more -- hence the index funds tracking the overall market (or just the traditional top companies like S&P 500) will generally do better. When the market goes tits up, pretty much everyone will take a hit at the same time, index-fund holders and people with more specific portfolios alike. The people that won't be hit hard will be those with more "safe" investments (that don't outpace inflation...) like bonds, those who saw it coming and invested in negative-indexes, or those who get lucky with e.g. penny stocks / startups.
I'd like to belatedly thank you for this lucid explanation :)
You don't "Learn to Code" so you can do it yourself. You do it to understand your business. Code will affect what your business can do, and when, more than you realize.

I don't see the difference between having cash on hand and having stocks. You can sell on the market five days a week. Add multiple credit cards with a very high credit line on them you effectively have about 30 days to sell stock from the emergency point.

Why keep stocks over cash? Even if they don't appreciate, or even if it is a down year, they still pay dividends which can be reinvested.

>And as I mentioned elsewhere, "free rent and free food" was basically exactly what the rats were given in their utopia.

You mentioned it and it's still inaccurate. The study gave mice everything they could ever want, in excess. This was food, space, and mates. The needs of mice are not complex. Basic income is just enough to let you sleep indoors and eat. If you were to create a utopia for people it would be fine food, entertainment, extravagant living arrangements, a complex and fulfilling social scene, opportunities for academic engagement, etc. Free food and rent is not a utopia for people by a long shot.

Be careful interpreting the numbers about how much risk is increased for certain genes. For example, let's say they point out that a certain gene increases the risk for some malady by 100%.

If the average risk across the entire population being used as a baseline was 0.02% (not 2 percent, but 2 tenths of a percent), then increasing that risk by 100% brings the risk to 0.04%, meaning 4 tenths of a percent, still a very low risk.

The point is, the way they present the risk numbers is overly alarming and designed to get you to buy in to the product. I think some people see numbers like 70% or 100% and immediately think that means those genes indicate a 70% or 100% chance of developing the disease. This is far from the case.

If I am not wrong, Netflix folks make heavy use of 'stream based programming' using RxJs. This greatly simplifies a lot of the standard problems faced in JS - like callback hell and error handling, if one adopts it consistently across the stack. Not many folks have discovered this as yet.
No, they are not C with all its flaws. They offer strict type checking, preventing a lot of constructs which would have unintended consequences when passing a C compiler. Modula introduced a proper module concept, without the need for header files without their issues, allowing for fast separate compilation of modules.

I disagree about every dev needing to have photoshop and knowing the basics - even though I personally have done this in the past i have found it to ultimately be a waste of time - something looks simple enough to change, sometimes you get lucky, it is, other times, 20 minutes later you're looking through photoshop menus/dropdowns. The designer know these tools the best, I'd rather take your third point and talk to the designer and communicate that you need him/her to be available to work through these points. There's so much for a developer to know and be focused on without having to learn to use the designer's tools as well.
