Why is this on HN? It's garbage.

The headline implies the brain has a global "framerate" implying it's synchronous. That's most definitely not the case. The strobe light and shutter examples are examples of the light and shutter having specific refresh rate, and has nothing at all to do with our brain.

So...

1. We have a study.

2. Then we have a mainstream press (New Yorker) article written by someone barely understanding the study.

3. And then we have this cheap blog post, whose author briefly mentions the New Yorker article, as an excuse to feed us a bunch of contrived nonsense that ties the study (as if) to some random meme GIFs and videos.

I think we're better than this, HN.
Your observation of kids blaming events or people for their 'bad' feeling, when they are actually hungry or tired is spot on. However this kind of causal relationship exists in far more subtle and extensive ways and stays operational all your life! Examples from research: judges give harsher sentences right before lunch vs. right after lunch. You are less willing to help others when you are cold. The list goes on and on.

Your kids becoming 'more logical and more consistent' is only them becoming so good at rationalizing and explaining their rationalization that you believe them. In fact it is still being hungry that made them lash out.
I think hardware wallets (like the Trezor), or smartphones with a TPM module is the solution.

This will take time, however (the latter more than the former).

The reason it will take time is that the concept of storing your own money digitally, like is the case with Bitcoin, is an entirely new concept that software and hardware needs to adapt to. With all other solutions (VISA, PayPal, bank wires), you're asking someone else to transfer your money, with Bitcoin you're doing it yourself. Basically, each user needs a greater level of security than PayPal, VISA and banks have internally, since Bitcoin payments are generally irreversible after an hour or so (and often much sooner).

This isn't something that is done overnight, and people have started working on it, but it takes time to, first of all, develop the hardware, and, second of all, develop and implement the interface between the hardware wallet and the actual payment request (ie. when I arrive at a BitPay invoice payment page, how do I pay using my hardware wallet?).
I want to add to the argument:
quite many people seem to be convinced that liquidity created by HFTs is almost a necessity for a pool/exchange to exist. What about pre-HFT times then? Did HFTs change the way we trade to the extent that it is impossible to trade without them now?
Liquidity is a measure of how much you can execute/trade immediately at any one moment in time. You can think of the fair price as the midpoint of the best bid and best offer -- but nobody can trade at this, so if you want to buy or sell, you have to buy slightly above the fair price or sell slightly below the fair price. And if you want to buy or sell a lot, you have to buy or sell standing bids/offers at prices worse than the best bid/offer, e.g. MSFT has best bid at 36.60 and best offer at 36.61 with 30,000 shares at every price. If you wanted to buy 100k shares immediately, you'd have to buy 30k at 36.61, 36.62, 36.63, and 10k at 36.64, for some average price slightly higher than 36.62.

So I would say that liquidity is not timescale dependent -- its a measure of the quality of your execution (relative to the fair price) if you executed everything you needed to right now. Personally, I would say no to (3) -- HFT offers liquidity at all times and only transacts when their counterparty decides to cross bid-ask spread, so if they didn't want the price HFT was offering than they wouldn't hit their bid/offer. The cost of all the ancillary infrastructure (wireless connections, backspace, hiring harvard/mit quants) is independent of the direct cost (crossing bid-ask spread) a consumer pays to the HFT, so the actual cost paid by the customer is a fraction of what the HFT has to pay to be able to display the quotes it does.

His corrected version

padded_size := (size + 2047) & ~2047

may be correct or it may not be, I can't really tell quickly because it's so oblique to me. Combining decimal and binary arithmetic like that is a bit too old school for me -- of course I still use it on occasion but I try to avoid it. I guess it's second nature to game devs.

What's wrong with

padded_size := ceil(size / 2048) * 2048

apart from the fact that it's much much slower but still really really fast in what I can only assume is a part of the source where performance doesn't matter, anyway.

Any thoughts on how this compares to simply spinning up a standard instance for a few hours then turning it off when you don't need it?

I run a service that needs to run about 72 hours worth of processing each day, and it all needs to happen during a 3 hour window. That's a natural fit for spinning up a couple dozen instances then killing them when they finish.

I'd love to see a comparison of what would happen if I kept the same amount of compute power on standby 24/7 using this new instance type.
Yes, truthful marketing is often less effective than deceptive marketing. I don't think that is a new or controversial point.

I think that the issue at hand is that being effective does not make it ethical.
Hey, thanks for your feedback! Calloud supports phone numbers from way more countries than Google Voice does, plus we are focused on building an awesome product for businesses, there are many things that can be done on top of our service, and we can't wait to roll them out. Additionally, Google Voice is expected to integrate with Hangouts (they are probably focusing more on B2C), so it might lose some of its current functionality http://phandroid.com/2014/03/18/google-voice-hangouts-coming...

The Wolfenstein Map Builder on the other hand was really easy and straightforward. I spend a lot of time building maps with that. Especially silly ones with a lot of hidden corridors (space bar on the wall). First "map" I ever built was just a big room filled with treasure :P

One thing I noticed upon moving to Europe (Ireland, specifically) is how much people seem obsessed with phone calls here. I checked on Vodafone broadband service and the next morning got annoyed at work by a call from a sales rep. I wanted to change payment info with my current provider and was told I had to make a phone call. I emailed a support group and their response was to call their 1890 number - something which costs 50 cents a minute to do, and is shockingly common here.

Maybe I'm just grumpy, but why is it so much harder to get things done here without going through the arcane and inefficient process of a phone call?

On the bright side, it's nice to see this lets businesses make themselves available without trying to charge their customers for the privilege.

I would much rather spend 10 minutes on the phone with my credit card company once every couple years contesting fraudulent transactions than have the potential for all of my money to be stolen if I make one security fuck up ever.

The number of "I had all my bitcoins stolen, here is the list of 25 security precautions I've taken, where did I fuck up" articles is terrifying. I'm willing to sacrifice the 1% savings or whatever it is I'd theoretically get from bitcoin for that peace of mind.
A credit card number is vaguely sensitive. It certainly isn't meaningfully private. A home address is similar, except it is less sensitive.

Totally agreed! A recruiter I spoke to yesterday said, "I see that you have a presence on GitHub..." referring to one of my more popular OS projects, and then rambled on for about 15 minutes about his open source friendly client. I'm not saying you want to attract lots of rambling recruiters (because that's boring) but it means that people are recognising hard work and OS contributions as a good thing. It helps.

Chrome is now a first-class citizen of Android; its tabs will now appear seperately in the multitasking menu. Android apps are coming to Chrome OS in windows.

If this is to be interpreted as a first step, I imagine that Chrome OS will eventually become yet another variation of Android. A variation focused on windows, and instead of bundled installed apps a greater focus on Chrome. But still with it all being Android underneath.

>All statements are true, false, arbitrary, or nonsensical.

And which was that?

AI depends heavily on statements that are somewhat true and somewhat false at the same time.

How distorted does a letter shape have to be before it stops being readable? How much does readability depend on context? How much does meaning depend on context? What if input is inherently ambiguous and noisy but there's a signal under there somewhere?

As for smarts, there are different kinds:

Abstract symbolic reasoning (e.g. pure maths)

Using abstract symbolic reasoning to predict possible futures (physics, engineering, finance, AI)

A talent for optimising choices towards an explicit goal through abstract reasoning about possible futures (all of the above, with brain-powered decision making)

The same, but using unconscious processes ('intuition') that are not explicitly abstract or logical (all brain, no AI so far, but still effective)

The author seems to be suggesting that the first two kinds of smarts don't necessarily translate into the second two kinds, for various reasons. And not all smart people realise this.

Well a c3.xlarge is $0.21 per hour (their "compute optimized current generation cpu" line).

24 * $0.21 = $5.04 per hour

You could burn those for two hours, almost, to match the lowest $9.50 per month cost of what they're talking about in the blog.

The c3 approach would give you 96 vCPUs during that time. The t2 micro for $9.36 or whatever per month, gives you one vCPU. I'd have to strongly favor spinning up 24 to 48 instances of the c3 large and clocking the job in one to three hours if possible.

It's $77 for 1 year reserved if I'm reading it correctly. That's $6.44 per month for an instance with double the RAM of the DO $5 instance. The specs look like the size that DO is charging $10 for currently. For a 3 year reserved instance it's $4.48 a month for double the size of the DO $5 instance. There's also a free tier, so the first year is free to try it out.

DO was competitive with EC2 on price but not on features (and certainly not on security), now with the price advantage gone...

Your question doesn't make sense to me.

> when can customers expect their money to be protected after they convert their savings into bitcoin, without trusting their coins to a third party service like Coinbase, and without spending a solid week learning how to safely store their coins themselves?

As you point out in your own statement, there are companies meeting the need for a "turnkey solution": you list Coinbase and they are an excellent example of a company doing that well and being quite successful at it.

You apparently reject them because working with Coinbase requires the customer to "trust their coins to a third party service". Trusting the third party service is pretty much mandatory for using ANY third party service. Imagine a hypothetical service that provided "turnkey" software to store wallets on your own computer -- you would still need to fully trust the provider of this service to ensure that they actually stored the money rather than siphoning it off someplace else.

The only way to (mostly) avoid having to trust a third party is to avoid using a "turnkey" solution that is fully packaged without user serviceable parts. You would instead need to learn on your own how to safely store the coins yourself. Which is ALSO a choice, and many people do it. You complain that it takes "a solid week" to learn how to do this -- and indeed, it does take a few days to become an expert on any subject; there are 10 minute tutorials, but I presume you (rightfully) reject them as being insufficient to really teach a user enough to be fully safe.

Honestly, I think that you are just being unreasonable in your expectations.
What the author describes is an US and in particular a Silicon Valley attribute. That of a concentration of smart technical people in their own bubble in a nice climate, outside of a wider community.

It's self selection filtering, it's team belonging and humans in groups. It's earnestness, it's bright eyed optimism.

It's not socially awareness, it's not a healthy cynicism. It's not cosmopolitan. It's isolation.

It's why the largest pure technical efforts and successes come from SV and why more socially concious and digital humanities and world humanitarian technical efforts occur elsewhere in the world.

I agree that the tone of the first chapters is rather neutral and objective or at least not as controversial as expected. I think the author's recommendations which by definition are subjective are to be found in the last chapter which I have not read yet.
Compare that page with the 'previous generation' page:
http://aws.amazon.com/ec2/previous-generation/

to see that there are new instance types, and they're cheaper.
And that's worth quite a lot, given Amazon's bandwidth is expensive. The 2tb in the Linode $10 account will run you about $200 with Amazon. Doubtful anyone is burning 2tb on a $10 account, and I'm sure Linode has that in mind, but even if you're using 200gb of bandwidth that would still cost you over $20.

there are companies meeting the need for a "turnkey solution": you list Coinbase and they are an excellent example of a company doing that well and being quite successful at it.

And if Coinbase goes bankrupt, all their users lose all their money.

I've written about this extensively several times before, so I won't rehash the old points. But the summary is, if you trust your money to an entity that doesn't have insurance, you're being very, very brave. Coinbase can go bankrupt for a multitude of reasons, some of which aren't fair.

One could counter this with, "Don't store very much money in Coinbase." Sure, but then consumers don't have much money on hand to buy things on a whim, which reduces consumer adoption. That's why I've been saying: Make bitcoin safe, and adoption will follow.
Ask HN: Looking for new career?
Little back story: I started professionally programming when I started a hosting company. With that I created small projects that used different API's and displayed the data differently or nicer.

Now I work for a financial institute and I slowly got asked and gained the skill to write reports for the company. I quickly learned I loved data more and displaying it in beautiful ways.

I want to change career to something that is related to data. I really don't know what is the title that goes along with what I want to do. All I know playing with data seeing how things relate and such is fun to me.

Question is: What is the title that describes a person who deals with data and displays it?
