The same reason the birds and the bees have radically different wings.

Scaling up insect flight to bird size does not go well, because physical properties do not scale evenly.
This is a good example of why it is better to be lexically scoped (at least by default, with a possible way to escape that). But I would have thought that clojure would be. Is it really not?
It is fairly common in zen publications to point out apparent exceptions to an otherwise binary system (i.e. Logical). It isn't seeking validation from science it is invalidating science as the be-all of understanding our existence.

Outside of zen (though very closely related). Phenomenology deals with this Subject/Object paradox our thoughts/language/science revolves around, and how it comes up short it describing some phenomena.

Ask HN: What sould 17-years old web designer sould do?
Hello fellas,

I'm 17 years old guy with a problem. I cannot get work. I live in Slovenia where it's nearly impossible to find any work, even in factory. Even if I could work in some design company I need proper education.

When I am searching for work on internet there is another problem. My portfolio is too small to be even noticed. I have worked for one semi big company, other two were collaboration with my friend.

What sould I do to fill my portfolio? Freelance sites are no go, Indians rules those sites...

Yes, nice, same here.

One question out of curiosity - on your IStorageQuery interface what methods do you have? Do you have the usual by Id's etc or do you have a query object that you pass in that can build/translate to the relevant SQL?
I agree with your accounting rules. The parent can be assumed to be following them, with plenty of room to spare.
That's a pretty broad generalisation. There is A LOT of eastern philosophy, so much so, that I doubt you've read even close to 'most other books' on it.

I'm curious of where in Confucius or Mencius critical thinking is discarded?

Though, ironically, Alan Watts actually has a number criticisms of critical thinking as well (in both article and recorded lectures). Zen (from it's daoist roots) isn't discarding critical thinking, it is pointing out its limitations.
Have a look at my link above. It's surprisingly good.

Maybe the article was also removed from google
Query object. The interface is as follows (I simplified a bit above:

public interface IStorageQuery<T,Q> where Q : IStorageQueryCommand
{
IEnumerable<T> Query(Q query);
}

IStorageQueryCommand is an empty marker interface.

Internally this is all bound to the query by property name.
No, this is about basic readiness for a number of contagions that are endemic to the region, which should be prominent on a list of healthcare priorities.

Nine years is a considerable time to be able to fix many of the problems you mention. After all those billions of dollars in aid, where is the infrastructure? Education? Compare to post WWII Japan or Korea...

And a comparison to the NHS behemoth - a model of mismanagement, waste, and inefficiency - is not a good one.
I guess if it's a choice between smashing into the ground and short period of spinning whilst an automated system landed the vehicle, I think I know what I'd go for.
Too much emphasis on number-crunching and bespectacled professors. Needs more think-of-the-children.
I read this presentation some months ago and I chose to stay with golangs builtin "database/sql". That way I'm using the purest solution with a well designed api. If I really wanted to use a 3rd party package I would choose sqlx because it stays close to golangs official sql package and carefully enhances it.

3rd party packages come and go but "database/sql" is here to stay.
Ah, but my favourite from that article: "You think you’ve made a choice, just as when you choose between two candidates preselected by entrenched political parties(No. 7—Choice is not freedom)."

Micropayment channels don't offer the flexibility of plain micropayments. Sure I can get $0.0001 from you a certain number of times, but I have to wait until I have a certain amount paid for it to worth it for me to make a transaction.

Micropayments that aren't channels will be possible when fees are lower.

Ask HN: What's the right time to launch a startup?
Situation:
I have what I believe is a good idea for a startup. The target audience would be unlimited, anybody could use the product.

Background:
I just started my studies this year (18 years old), and I fear that if I launch a startup, I will have no time for studying or other important experiences I would normally have at this point of my life.

This video validates these suspitions (I think you all know it):
http://startupclass.samaltman.com/courses/lec03/

Question:
So I wonder if I should decrease work by concentrating to a certain, far smaller target audience. The product may then not be worth a startup, but rather a side project, that will also probably not pay off.

So here are the options I currently see:
Should I waste no time and implement my idea, should I reduce the target audience or should I just wait for the right time for my idea?

It's like you went out of your way and collected every incorrect piece of knowledge about bitcoin.

> Bitcoin can't handle micropayments

It already does.

> The block chain is limited to about 7 transactions per second

No, it doesn't. That limitation is completely artificial and can be removed at any time. The core developers are working on scaling the system to 1000+ tps.

> and it's currently about $0.30. That's more than many merchants pay to process a credit card transaction.

No, it isn't more. And it's $0.03, not $0.30. Have you looked at the actual credit card fees? They consist of a percentage + fixed fee per transaction + fixed monthly fee.

http://credit-card-processing.findthebest.com/

> Nor can Bitcoin handle fast payments. It takes about an hour to get solid confirmation of a transaction

The transaction takes a few seconds. One confirmation takes around 8-9 minutes on average (we always mine faster than the 10 minute goal).

Compare it to a bank - transaction takes days, confirmation takes 6+ months.

Compare it to a credit card - transaction takes a few seconds, confirmation takes 180 days.

> * you're selling anything that actually costs you money, you have to wait for some confirmations*

Same with credit cards and bank transfers. Except these kinds of payments can be reversed for 6+ months, and it's a big headache for the merchants and stores.
The security is based on the premise that Apple is unable to decrypt as they do not keep a record of the devices unique ID that is the base of all the cryptography.

What if that is not true?
What if the device has a built-in keylogger to just get all the crypto from the user input? be it a passcode or a fingerprint.

Wouldn´t it be partly better if this were based on a trully public key cryptography with a randomly generated private key generated each time the device is factory reset?

The Wikipedia page on double checked locking[1] is pretty good. It's got a good discussion of this C++ problem (and how C++11 fixes it) as well as the problems in Java (prior to JDK 5).

It seems reasonable that when you decompose the representation of the target function you are trying to learn into more layers, each of the layers can be "more gently" modulated to emulate the target function as observed through the training data. Differential techniques might therefore more readily find good approximations to the target function. Once the structure has been captured by finely slicing it into more layers, this structure can be compressed down into a shallower representation.
That's correct - at ClusterHQ (makers of Flocker) we are focusing on using ZFS for volumes. ZFS itself is a copy-on-write filesystem, but we're using snapshots so that we can do send/recv between hosts, as opposed to using snapshots for the layers in a Docker image.

Separately to the work we're doing, the guys at Gandi (a European hosting company) are working on ZFS support for Docker images - see https://github.com/docker/docker/pull/7901

Combining these two efforts could result in a pure ZFS-on-root Docker distribution, which uses ZFS with Flocker for volumes, and ZFS for the Docker images themselves. That would be pretty cool, IMHO. ;)

I tried one yesterday for the first time. It was a DK2, it was very low resolution, and you could clearly see the colored pixels of the display.

Text had to be very large, so only three or four lines fit on the screen at a time. After hearing people praise the DK2, I thought it would be basically seamless, but it was jarringly low-res.

The experience was great, very natural, but the pixel density left a lot to be desired.

Nobody is "not invited". The problem is that the venture capital industry actually forces people and companies to move to San Francisco as a condition of investment. And all I want is for people who do not actually want to live in San Francisco, but are there because either their job or their investors made them move, to be allowed to live wherever it is they actually want to.

The software industry could be leading the way toward location independent businesses and bringing economic life to places that have been screwed out of their economic vitality by globalization. Instead, it is forcing businesses, many of which would gladly locate themselves elsewhere, to pack all of their employees into a 7x7 grid that does not contain enough housing both for them and the people who already lived there.

I work for an organization that provides services and advocacy for homeless people in San Francisco and I see the effects of this stupidity up close every day. It.needs to stop. We don't need to kick anybody out of the city, we simply need to just let people live where they want.

What's wrong with wanting to abstract something that only the database care about? when you want to read a file in go,do you execute a shell command like "cat myfile.txt" and pipe the result? or do you use a pure go api ?

Each time you do an http request,do you send headers and body through tcp sockets as text,or do you use an http api?

Perhaps when the Oculus HD comes out. At the moment the text would be in such a low resolution that it would make it not worth the time. Pre-emptively creating an app in preparation for the Oculus HD might not be a bad idea however.
IRC bots. Being a system administrator I don't generally have a need for UI coding. IRC bots cover networking, just about any sort of text processing you could need. Add in a standard complement of "tools/utils" and you can also add in "plugins/modules" to also toss in database handling, fetching and storing of data, etc.
yes, but then you have to take the lower resolution for granted. I think I might still be more productive with a single HD monitor.

Sharia actually prescribes death (which is exactly what they are planning on doing with that developer) in the case of insulting Islam and/or "prophets". A direct quote from the Islamic website:

"The scholars are unanimously agreed that a Muslim who insults the Prophet (peace and blessings of Allaah be upon him) becomes a kaafir and an apostate who is to be executed. This consensus was narrated by more than one of the scholars, such as Imaam Ishaaq ibn Raahawayh, Ibn al-Mundhir, al-Qaadi ‘Iyaad, al-Khattaabi and others. Al-Saarim al-Maslool, 2/13-16"

That hmd has only a 40 degree field of view, as opposed to the rift's 100 degrees.

FOV is normally diagonal, so for 800x600 we have 1000 "diagonal" pixels, and for the rift's 960x1080 (per eye) we have 1444 "diagonal" pixels.

So that works out to:

1000/40 = 25.0 pixels per degree for the z800
1444/100 = 14.4 pixels per degree for the rift

So the z800 would have almost 4 pixels for every 1 pixel of the Rift

In fact, it's even less for the rift because the DK2 doesn't have a standard RGB display but pentile pixels, which means you only have the full 1920x1080 for the green subpixels, the red and blue are reduced since humans are less sensitive to those colours
Sorry, I only tried it for half an hour or so and saw that it only displayed three or four lines. 16 lines is probably doable, I just meant it can't display an entire Web page, like a screen can.
As others have mentioned, when the assumptions of conditional independence are met, Gaussian NaiveBayes and MaxEnt will asymptotically learn the same classifier. Except NB will learn it in O(log dimensions) instead of O(dimensions) examples. So in those cases and where you have fewer examples you'll want to use NB.

Even when the independence assumptions are not met, NB will often produce a good classifier if you don't care about the accuracy of the probabilities. NB is also online, resistant to the curse of dimensionality and for categorical data will learn polynomial decision boundaries. So the gain in the trade-off is in ease of implementation (you can write one in a dozen lines or less) that you can throw something close to your raw data at and often get good enough results without any ahead of time training, kernels or regularization.

You are right though that MaxEnt (some sparsity capturing algorithms are as powerful as SVMs) will in general outperform naive bayes and that the averaged perceptron probably has, on average, the best performance/ease of implementation ratio. But for many implementors/problems, where clarity is paramount, those distinctions will not be worth the cost.

Also, you have a wonderful website.
I own a DK1 and the low resolution makes text reading incredibly difficult. DK2 is a step up but text reading still strains my eyes. I think the 'sweet spot' for us coders will be when the DK4 hits market late next year (DK3's supposed to be out early/mid 2015).

As far as I know no ORM support arrays natively.
I have a few projects made around sqlx, and I had to support arrays. So I ended up doing the support myself.
This is why I bought a DK2, I believe VR IDE's are going to be a thing, and they're going to be great. The fonts aren't very crisp in this video, but once we get some nice editors in there it's going to rock, the new display has a high enough resolution to make it look great, and I bet the consumer version is going to have a retina display which will just make any discomfort vanish.

Note that in the video there's just one editing window, in an IDE obviously there could be editing windows and references all around you. You would never need a mouse as your head movements convey positional information, though you can use a mouse of course, and with good keyboard controls I think you can have an editing space ten times as big as the traditional dual 27" monitors give you.

No more hiding buffers in tabs, no more disruptions of flow as you're scrolling through your buffers looking for the right one. You just access the visual memory in your brain to intuively remember where you left the buffers you use.

Also, the idea that this would somehow be bad for your neck sounds ludicrous to me, how is staring for hours at a stationary rectangle with miniature information more natural and easy for your neck muscles than having information spread around you in even spacing at a comfortable virtual distance? I think it's going to be a relief for nearly everyone.
This demo begs for drag n drop interfaces.

I'm no sure the point your making, but you appear to be agreeing with the OP.

At the end of the day you're still doing object relational mapping.You just built something custom instead of using Hibernate,so you're still using an ORM.

Your domain objects are still a graph that need to be hydrated from the database. And dont tell me that writing hydrators by hand is fast and dry,especially when you have 100+ domain objects,compared to a few XML files or annotations that can later take advantage of query builders or HQL.
do you code with the following languages PHP, MySQL, HTML, CSS, Javascript?
I've always thought that in languages where functions are first-class, a function referring to itself via a name binding is strange, since the function is supposed to be a value just like any other. Values like 33 or the list of foo,"bar",7.5 aren't aware of which names (if any) are bound to themselves and that's how it should be.

The so-called recur* in the post sounds like an improvement.
