Ask HN: Tablet Choices
My girlfriend's birthday is on Sunday.

She needs to replace her laptop. Ideally, I would buy her a Macbook Air. Unfortunately, she is dead set on a tablet of some sort. She was excited by the Courier video a few years back.

She really wants a tablet with a good keyboard solution. I think Surface is the best bet on it. What do you guys think?

I narrowed down the list to:

Microsoft Surface RT -
iPad 3 - Refurbished, seems like a good deal
iPad 4 -
iPad Mini -
Asus Transformer Prime -

I added more notes on here, vpena.sqsp.com/2012/10/24/on-tablets
Never thought, this would be a hard choice. I know Monday the Nexus 10 will probably debut.
Interesting... If we ignore the zeros and the 20/35/ba, it looks very much like the 7 digit short identifier of a git sha1.

Maybe it's just announcing a continuous deploy script saying that a particular build made it to prod/staging?
But some undertakings are simply too big for private corporations, and require government funding and control.

I don't think it's the size of the undertakings as much as their time horizon. Corporate time horizons just aren't long enough to comprehend investing now in, say, a manned Mars mission in 2030. Even at a pretty low discount rate, the net present value in 2012 of resources mined from Mars in the 2030's is effectively zero to a corporate bean counter.

The problem is that government time horizons are even shorter. The TR article talks about NASA having the technical knowledge to send men to Mars; but we had that technical knowledge in the 1970's. The problem is that, since the Apollo program (which was, I think, an outlier in this respect), the US government simply hasn't had enough consistency of purpose to reliably fund ventures that last beyond a change in the party that controls the White House and/or Congress.

I think the real problem is stability, i.e. how do you keep aerodynamic forces from spinning the (unguided) capsule too fast during reentry? If you look at video of Baumgarter's free-fall he is spinning very fast -- a couple RPM I'd estimate -- when he begins his deceleration after the near-vacuum free fall.

Orbital reentry would last for minutes and at much higher velocities. The centrifugal forces generated by unchecked rotation could cause blackout or even death. You'd also need to figure out what happens if your heat shield is not heated evenly due to rotation.

Guided reentry is a solution, but then we're talking RCS thrusters, fuel tanks, guidance equipment -- maybe something you can strap onto a spacesuit, but approaching a spaceship. And then you need one for each astronaut, increasing weight and complexity.

Not that there was much meat in the article, anyway, but at least the following is mildly insightful:

I prefer Python to R for mathematical computing because mathematical computing doesn’t exist in a vacuum; there’s always other stuff to do. I find doing mathematical programming in a general-purpose language is easier than doing general-purpose programming in a mathematical language.

If the intersection of those domains is unique, you're knowledge is more likely to have value.

This is categorically false. Multimethods solve a certain problem "open arbitrary function dispatch". Nothing in Clojure aside from multimethods solves this problem. There are many projects that use multimethods to their great advantage, including, but not limited to:

* Clojure

* ClojureScript

* ClojureScript One
That's completely true, I'd also add in:

Totally go for the surface, if money is no problem I think ATM there is no other tablet I would buy. Other way the Transformer is great, but if it's a laptop replacement I would still go on the Surface to avoid risking the need to buy a laptop later because she feels the tablet is not enough.
Also, the current military challenges that the US faces aren't things that can be solved strictly through technological innovation. It's asymmetric warfare, so there's very little incentive for the US to invest heavily into new tech.

So remotely piloted drones, small weaponized robots, and ever more precisely targeted guided munitions don't count as "new tech"?

To the best of my knowledge, R&D funding for new technology that might have military applications has, if anything, increased over the last 10 years or so.
How does it work for a minor using Facebook? Are their accounts public by default? Can they friend and be friend-requested by anybody? Are they linked to their parent accounts somehow so that parents can monitor or approve requests? When they become an adult, is all of the data/content/history going to stay with the account? So when they are 20, friends can see what they wrote when they were 12 if they dig into their history?

(I am not very familiar with Facebook but I do have two young kids who will probably start wanting it soon)
Any tips on how I could be saving in this situation?

My service Candy Japan gets most of its money via PayPal in USD. I have to convert this to EUR to get it to my Finnish bank account. Then from the Finnish bank account I need to transfer it to my Japanese bank account to actually be able to buy the product and pay for shipping here. Neither accepts PayPal or debit card directly.

I created my PayPal account when I was still living in Finland, so it doesn't offer me the option to withdraw directly to Japan.
I don't think I'd regard "artifical general intelligence" as "easily solvable" - unless I've missed some developments in the field I don't think we are much closer to understanding how to engineer a general human-level intelligence than we were 20 or 30 years ago.

No. Saying there's one exchange rate is a fiction.

I used to lead the development for currency pricing algorithms for a major market-making investment bank.

Think about the way the market works fundamentally. You have people who want to sell at rate X and people who want to buy at rate Y. These form the basis of the bid/ask pricing, if the values cross then the people involved can do a trade.

A retail currency exchange broker will add their spread on-top of the market bid-ask spread, but that doesn't alter the fact that there is a fundamental underlying spread caused by differing views among the buyers and sellers of the currency.

There's also not a single market which can have a mid-price. Currencies aren't like stocks where there's a single point where the trades happen. There are lots of currency markets and at any one point in time they'll have different fundamental bid/ask spreads (because of latency), you'll also have differences based upon volume and market depth, who's willing to trade with you, and the participants in that market (many bigger trades now happen in private dark pools).

So once you've picked what your definition of market is then you need to pick your definition of midpoint. Are you going to take the middle of the bid-ask, are you going to take the price the last actual trade was done at, or a volume-weighted average price, are you going to filter out momentary spikes, are you going to filter out prices from people who are purposefully market manipulating, etc. What about when there's low liquidity and price might be wildly off ?

And that's all stuff that's required to just arrive at a market price. You have to take a subjective view on every-one of these decisions, so in practice any serious market participant is going to have a slightly different view of what the market is for any currency.

On the point of offering a fixed single exchange rate, yes it's possible, but the the broker offering it (1) has to make their profit from somewhere other than the spread and (2) take the risk that if the market moves against them that they'll lose money (and again the cost of this has to be covered elsewhere).

(2) is actually a huge risk. If the market moves so your price is outside of the market bid-ask range then someone can arbitrage you and make risk free profit from your out of market price and basically bankrupt you. So to defend against this you either need to be able to stop transactions if this ever happens of put enough of a delay in your system so you can make sure this never happens.
Out of the box Rails solutions with integrated payment systems scares me as it allows people with little Rails experience to quickly allow payments.

I'd parallel my concern to beginner developers who create Rails projects that don't check for User ownership when navigating to /edit paths.

Implementing Stripe is almost a small rite of passage. It forces you to understand the API, and how it treats payments and other various objects.
As the article mentions, most of the emerging economies that are starting to be affected more by the yuan than the dollar are in East Asia. That only makes sense, anyway. The dollar isn't being displaced as a key currency, it's losing some prominence in emerging markets--which, if they're ever to emerge, will float freely, anyway. It's exactly what you'd expect.
It's pretty obvious that neither the Republicans nor the Democrats are willing to cut down on spending enough to start chipping away at the national debt. Hopefully the (partial) weakening of the greenback's status as the world's primary reserve currency will force them to take action.
If you personally don't care for them that's fine, but the x230 is about the same weight as a macbook air. It's also one of the only ultra portables that you can add ram and an ssd to on your own. If you can get past the design (many of us actually prefer it) then an x230 with an ssd and 16gb ram is a pretty compelling option.
That's the idea behind currencyfair.com. The user experience is a little clunky but the rates are much better than anywhere else I've found (I send more than $2k a month to the UK so I've shopped around a lot).

Here's a way to easily pull down the data without all of that extra gui stuff: https://api.twitter.com/1/statuses/user_timeline.xml?screen_...

The maximum is 200, but you can move down the line by using since_id or max_id optional parameters.
'xml' can be replaced with 'json' or 'rss' if you'd prefer a different format.

Looking over the data briefly reveals the additonal fact that the 'source' field is populated with a link to Google. That, combined with the other accounts including one that outright says it's associated with google on its profile. So this is either google maybe doing some sort of recruiting thing, or somebody that wants us to think it's google for whatever reason. One guess is that the account name could mean Google User Notification Service.

Additionally, the tweets are published at a (more or less, this is the web) regular interval. Always around the HH:M9:30, HH:M0:00, and HH:M4:30 and HH:M5:00 marks. As stbullard speculated (https://news.ycombinator.com/item?id=4697813), there could be two instances of whatever this is running, publishing every 5 minutes independently, with one instance having the code baf200000000 associated with it and another having the id of 2350000000. Note that the length of these two are different- the former is 12 while the latter is 10. This could mean a variety of things regarding the format in which the data is published, or variance in the data itself.

It might be worth looking at the unique parts of the 235 ones as color.

If anyone can pull these tweets down into a single file and share them that would be amazing.

On the corporate desktop? Not really. Apple is still making no effort to sell to the enterprise, and few people are selling linux there.

joonix: you're quoting out of context, and you're a brand new user... that's interesting.

As Silver explained right above the sentence you quote, a sophisticated trader could have easily arbitraged the spread by buying Betfair's Romney contract at $0.37 per dollar, while simultaneously shorting Intrade's Romney contract at $0.45 per dollar -- a sure thing!

Silver then added that $18K "...is a large bet in everyday terms, but not by the standards of a professional gambler or investor who felt he had a sure thing." A truly sophisticated investor seeking to make millions instead of merely thousands, he explained, would look to larger, more liquid markets -- like the stock market.

Please don't quote out of context again.
Well, it does actually define locals. But, IIRC, it uses the symbol hash parsing productions, so the default values are required. The only way to specify required parameters (without the above hacks) is to do a traditional method definition:

irb(main):001:0> def foo(bar, baz: Object.new); [bar, baz]; end
=> nil
irb(main):002:0> foo(1)
=> [1, #<Object:0x007fbc39161ed8>]
irb(main):003:0> foo(1, baz: 10)
=> [1, 10]

What you raise is a valid concern, but is it better for a new developer to work off a best practice style example app or try to reinvent the wheel on their own?

I share your point of view. In this case, the code is much more of a "starter app" than an "out of the box" solution. There's a good amount of customizing and tweaking required before the app can be deployed, which will encourage an inexperienced developer to gain some skill. The tutorial helps; it's probably the most detailed introduction to the implementation issues of a membership site and Stripe that is offered anywhere. The intent is to be a mentor for the "rite of passage."
No not really, although if I was in need of some kind of option, I would explore a couple of things 1) Clipboard formats... like WMF on the clipboard into Inkscape 2) Printing as PDF or PS and then using Inkscape or Ghostscript to go from there... 3) See what kinds of options you get with obscure features of Photoshop like AI->Photoshop->Print as PDF ... in general I think for large complex drawings AI suffers from losing track of its own internal scene graph, or at least there are drawings and layers of effects that can suffer from the halting problem and just crash AI. I have seen several people in the creative coding and graph theory worlds struggle with this kind of problem regardless of tool. Best of luck to you!
I'm not sure I buy the idea that this is as simple as the Federal government wanting to ban all currencies that are not the dollar. I don't buy it because there's still no sign of them trying to crack down on other alternative currencies such as Ithaca Hours. And Ithaca Hours are, I believe, older and more well-established.

It wouldn't be the implication that the alternative currency has a cash value in US dollars, because Ithaca Hours are pegged at $10 per Hour.

I wonder if it's that the Liberty Dollars were issued by a for-profit organization rather than being community organized like other alternative currencies I'm aware of. If I remember right, the "dollar monopoly" was originally enacted in response to the fracas around Civil War tokens. During the war companies had been issuing their own scrip that started to be used as currency in the surrounding communities. There were a number of minor financial catastrophes that happened whenever the issuing company would stop honoring its scrip, thus causing the currency to collapse. And the scrip issuer essentially made off with however much US currency they had received in exchange for the script. So the government decided to ban that as a form of (at the time clearly much-needed) consumer protection.

Anyone who's more knowledgeable about the applicable law and its history who can comment?

The cash market spread is usually something like 4-6 basis points for major pairs (i.e. 0.04%), even accounting for the fictitious mid rate, you still have orders of magnitude difference from the retail spreads. Thomas Cook, a major UK travel agent, is currently offering around 6% for GBPUSD going by their web site.
Not being a US citizen, I'm always quite stunned by what I perceive as an obsession with polling results. Especially when fundamental flaws in the US voting system (see, for example, http://www.gregpalast.com/latinos-too-lazy-to-vote/) seem to get widely ignored.

Sites like http://fivethirtyeight.blogs.nytimes.com/ may be great in bringing insightful reflections on statistics to a larger audience, but by focusing exclusively on the maths of elections, they might actually reinforce this ignorance towards actual political issues.
[…] On a larger scale, the Council inaugurated a set of projects ambitious both in scope and name, intended to be Manhattan Projects for a new age: Project Eden sought clinical immortality, Project Janus sought FTL travel, and Project Icarus sought to use solar satellites to harvest the light of the sun, making energy not just cheap, but free. With these accomplishments, the Council sought to win eternal loyalty from its citizenry.

Now we're talking grandiose programs that could very well have the support of the population. (Even project Eden: give people actual hope of escaping Death, and most will cease to object.) If a governance actually successfully triggers such accomplishments, I'm sure going to like it more.

Aren't "market-sized" deals measured in millions because banks are making one deal to cover lots of smaller deals that they've made with their own customers?

If someone can cut out the middle-man and let the small deals trade with each other directly, there is no reason why people can't get the mid-market rate for a trade of $100 never-mind $1000.

This is the idea behind currencyfair.
