The problem with a pin system is that I have a like 8 cards that I use pretty randomly. While any of them can have a pin, the only one I know is my ATM card. I can't imagine how people do this with multiple cards and multiple pins without a password manager or some algorithm.
Uhh ... Postgres supports Index-only scans; as long as the data you're asking for is in the index, that is.

So if you have an index on (conversation_id, message_id), and you try to retrieve message ids of a specific conversation, only the index will be touched.
Canada will provide better metrics soon enough. Nearly every bank there has rolled out Apple Pay system, and contactless payments are ubiquitous in Canada. Apple Pay is only available for ANZ here, while rest of the banks are rolling out their crappy payment apps.
During initial development we are starting out with bundeling our angular app with the api by serving the angular app as dropwizard assets. There we use webpack-dev-server in proxy mode for easier development with livereload.
We don't like the complexity of seperation from the start. If we run into problems (assets need to scale differently than the api) it's pretty easy to extract the static angular app and serve it via a separate webserver.

Those are all massive scale tech companies that actually needed to invent many of the datastore technologies used for big data today. Uber is not among them.

But I'm sure you know all this as it seems you work for an enterprise database company that actually makes the exact product Uber should use.
Um. Yes. I did actually describe the opposite of what is in the articles didn't I?
I don't think that there's an actual legal difference (though IANAL) here. Signatures and PINs are both effectively affirmations of consent, and only the authorized cardholder is contractually allowed to consent. If you deny that you gave that consent the process should be the same either way, you sign an affidavit to that effect if the CC/bank wants you to.

The difference is that not just anyone can draw an X on a terminal after skimming your card to pretend to be you. They need an extra piece of information to do so. They are still breaking the law by using your card, and it's still something the processor has insurance against.
This is the tool I was hoping would exist. Looking forward to trying it out.

> The only point of note is that there was a coordinated effort to take this option - one which will not likely be possible in a future larger network.

Saying "this is possible in Bitcoin" despite its large size then try to downplay Ethereum's same risk when it gets bigger just seems an odd way to justify Ethereum's value to me (an outsider to all cryptocurrencies). Between the two, Ethereum has the proven history of generating the coordinated effort. Bitcoin does not. So if both are the same size, the cryptocurrency's specific community and history is a factor in its value. I would rather avoid the smart contracts that Ethereum has as it seems like a liability.

> Here's to the crazy ones who flew in the face of adversity, success or not.

No. My whole point is that they only chose the proven (and famous) 'crazies'. There's only room for 'success'. No room for the 'or not'. Stallman is proven to a niche of techies, but outside that niche, people think he's a whack-job, despite his profound effect on computing as a whole.

I've got a high opinion of Stallman, but Stallman is very much the kind of 'crazy' that Jobs would want to hide. Not 'bankable' enough.
Isn't there something like Paywave there? I used it for 90% of my transactions in Canada. Only have to use Chip n Pin when going over $50.
Absolutely. After 3 months of using it I have only withdrawn cash from an ATM twice.

It's slightly amusing to watch the cashier have a moment of confusion as I ask to 'pay by card' then proceed to do nothing whilst I wait for them to get the EFTPOS terminal ready. They expect some kind of shuffling to produce a card instead I extend my wrist out to pay with an Apple Watch.

Can't wait to see what numbers come out from this, interested to know % of Apple Pay transactions on activated cards.

It is a fact that both interest rates and the price level were exceptionally stable during the international gold standard, which lasted roughly from 1870 to 1900. This 30 year period showed a stability in both interest rates and the price level that has never been seen since.

Now, whether this was due to the gold standard, or whether the reason was one (or more) of the other trillions of factors that are different between now and then, we cannot say.
The difference is: when Chrome updates, it doesn't force me to update everything else on my system. Apple uses a "version ratchet" to force you to update everything whether you want to or not.
I consider this a great paper to start from if you're interested in experimenting with computer composition. Bringing it up to date with a deep learning network would probably make for another nice paper.
A solution: everyone is sequentially numbered. Evens rotate left one round, odds rotate right the next round. That way everyone has to move the same amount (assuming an even number of participants).
It makes sense volume would be high on ETC, the market is trying to resolve its price. The price of ETH is basically what it was before.

It also makes sense that it would be making big gains. It just crashed basically to zero, there's nowhere to go but up.

Neither of these metrics suggest long term viability to me. Although I am surprised it's trading as well as it is. 10% of ETH is pretty good!

NFC is not NFC. The US NFC often is MSD and not EMV. Also many terminals explicitly only permit Android and Apple Pay. Not a general issue. I used my cards in many other countries, only ever an issue in the US.
If I understand you correctly, not everyone then sees everyone else, which is likely to breed customer dissatisfaction
Anecdata: I think there was a period where stores didn't know they had it on on their POS', so it was a little more widespread out of the gate and then went back down as they disabled it. But that process seems more than reversed now.

For the most part the holdouts have been restaurants, as many POS devices had the tip/authorize order backwards (if enabled, tap would bypass the tip step). That's changing now and I've been to a few restaurants with tap now.
While I suspect that this is true in practice, this is the disadvantage that you don't talk to everyone, even though you can see them.
I started thinking about computer music generation when I met Peter Langston (http://peterlangston.com/Papers/amc.pdf) who was contracting with Sun doing audio work on the original 'project green' star-9 device. There were many places where being able to play a tune of a typical "flavor" but royalty free was required. I just thought it would be nice to have continuously variable music on hold.
"nation-state adversary" and "logical AND" both cracked me up. It is surprising to see common themes with my own research on this topic: "thinking too much".
> Now that guy is complaining that the photos app icon doesn't look like a Point And Shoot camera, when fewer and fewer people use those.

Actually a problem with this icon is that it is misleading. The iPhoto app is not a camera app. It is a photo library with some minor editing capabilities. You can't use it for creating photos which is what the icon suggests.

A better icon would be a photo album or a stack of photos but that's hard to fit in an icon.

> and somehow made the user experience much worse

That seems to be a problem with implementation, not technology. Outside of the US, I could use contactless payment with a card for years. I could also use chip payment under a specified limit without putting in PIN. Even if all that fails, terminals which are actually connected and don't use dial up on every payment take just a few seconds to authorize each transaction.

The US payment systems dragged their feet for so long now you get to experience payments in Europe from early 00s.
This way you see everyone, but have a logistical nightmare.

So you say Apple users had no choice? How about making the choice to buy, say, a Mac, so you can focus on what you do ON you computer, not on what you do TO your computer?
I work with imaging systems that identify medicines. While they are wildly simpler in terms of analysis (basically using the silhouette to calculate shape and size), most attempts to add colour to the equation ends up adding a new, complex element that the inspection can fail on. Mostly because colour is inconsistent under varying lighting conditions.

Again, very different systems, but might be relevant when considering if straight contrast is enough to work with or not.
Aren't you able to just tap your chip card on the terminal without a pin for purchases less than ~$100?

I work in retail. Failing to start processing upon insertion is a bug, the screen telling you to insert is a warning that you did the wrong thing not an expected part of the process. I have seen a weird issue wherein some cards, always the same cards don't start processing until you try and fail to swipe. I have no idea what the difference is as it doesn't seem to be a single issuing bank.
I agree. I have an old 'dumb phone' and I appreciate that I can use 2FA without a fancy Android app.
In the same vein, there are also some F# to JS compiler projects such as Funscript (http://funscript.info/) and Fable (https://github.com/fsprojects/Fable). F# is an open-source Ocaml inspired language for .net.

European banks have been able to allow cross-border operations for decades. The "banks can't agree on rules" is mostly an american problem.
Why do you think banks care that much about depositors storing money in them?

The main way banks make money is by lending money, which also creates matching bank deposits. They do require some reserve-backed deposits for liquidity, capital adequacy ratios/reserve requirements, but not that much.

I think the problem is even a little more subtle. The thing a programmer should ultimately aim for is to automate themselves out. But there are two strong disincentives to doing so. One is economic - they don't participate as a stakeholder equally unless they're cofounders.

The other is a disincentive to improve. By this I mean that becoming a better programmer means taking on deeper challenges and solving increasingly obscure concerns and constantly reaching a point where no IRC channel nor Stack Overflow thread can help you. This takes you out of flow. It's not fun to work right up at the limit of your ability, you have no hope of bullshitting through that level of difficulty in crunch mode, and developing those skills alienates other programmers who are not burdened by the demons you have fought. Plus the majority of software businesses have arranged themselves around making some use of fresh, mediocre coding talent, so going too deep and too specialized can make you less hireable!.

So it works out that prevention with good engineering can grow discouraged in favor of all nighters.
Combat Hearing Loss – TCAPS Modulate Sound for Soldier Safety
Blockchains fork constantly. Most forks aren't ever treated as a source of truth by anyone, but there's always the freedom to do so. We've created these fancy spools of receipt paper and we're all just trying to decide which one to pay attention to. Software can never make that decision for you, nor can a particular development team. I consider the freedom to choose one's own source of truth to be valuable. Others seek to force people to treat something as the truth even when it says something they disagree with, which is untenable without the use of actual force.

Blockchains are as immutable as the people who look at them decide they are. They're still pretty useful for creating reliable sources of truth.
I live in Australia and since we already have contactless payments everywhere I don't understand the benefit/s Apple Pay provides over tapping my card on the terminal. Am I missing something?
Crazy. In the modern world phone books seem like highly exploitable resources should your designs be nefarious.

> I really wonder why people seem to like Finder over Windows Explorer.

IMO the main problem with Windows Explorer is the UI changes so often it's kind of confusing to do really basic tasks sometimes. There's so much functionality buried under toolbars, contextual menus of different kinds, nested property sheets, etc that any change to the UI effects a lot of things. For example in one release I always had to remind myself to right click on 'My Computer' in the Start Menu to get the contextual menu that included 'map network drive' because right clicking in a My Computer window only offered 'add network location' which is something different.
>But intelligence officials have cautioned that they are uncertain whether the electronic break-in at the committee’s computer systems was intended as fairly routine cyberespionage — of the kind the United States also conducts around the world — or as part of an effort to manipulate the 2016 presidential election.

Does this bother anyone else? I appreciate that the NYTimes is willing to print an admission that the US also plays rough in cyberspace, but only probably because public awareness of this already exists. It appears as an attempt to setup the possibility that this hack was not "fairly routine cyberespionage which the US also does" which is apparently OK, according to the NYTimes, but as possibly some other type of malicious hacking.

So what they're saying is: Nation state hacking is OK, as long as it abides by some untold, arbitrary guidelines, but we're not sure yet as journalists yet how to spin this any further.
Reminds me of The Antikythera Mechanism by BT (This Binary Universe) [0]. Each "loop" sample isn't because it's subtly different from the previous one, and when a phrase loops back again, the context changed, creating progression all along the song.

I know everybody would love to see this, but for me it's a bit much to ask from Google to open-source Firebase since they invested quite a lot of time and money into it to get to the current version. Apart from that, I can definetly recommend http://deepstream.io as a Firebase alternive, although it currently lacks an Android/iOS client (Java client is in the works).
Same here. While the author has a point about laptops as a workspace he fails to distinguish between generally accepted best practices and his personal opinion. I've yet to see any totally flat keyboard to be recommended as ergonomic.
On the other hand, we call this thing a computer, while only the fewest use it to actually compute something. Or, we call that other thing a camera, while it's some years since this was actually a room, you could enter. Such historical traces may be found in visual language too, e.g., we commonly use arrows to indicate directions and relations, while they aren't found in real life anymore (at least, the fewest use to shoot with them nowadays).

These historically grown metaphors make lot of sense, where it comes to how we relate to objects. The word "camera" isn't only short and distinctive, it's also evoking a sense of the history of the medium, and it may provide some emotional bonding to the object which may hardly be achieved by a "multi-image" – while the latter may actually sound a bit fancier in a 1970s SF-movie. I think, there are some valid points made by the article, and, besides, on an empirical level, I'm losing time in the newer, uniformed MacOS GUIs, too. (Not to speak of Miller's magical number 7 or 3.7 bits working memory, which are still valid in the age of flat design. But this is an other story.)

Signatures are absolutely worthless as far as preventing fraud. In the first place the proposed thief has access to the signature in question, signatures on electronic pads are horrid, and cashiers aren't trained handwriting experts.

Basically anyone could make a signature enough like the signature visible on the back of the card on the electronic card to be no worse than the average signature as far as the average person verifying it is concerned.

This is why zero fucks are given regarding how authentic your signature looks even if they look at your card. The 2 things that do prevent fraud are verifying id and cards that have pictures of the user on them.

If you're not a fan of submodules, but are in need of a this kind of tool, I'd recommend looking at `glide` [1] . I've had much better experiences, as a user, with `glide` than other tools, and it supports package aliasing which is really helpful. (Package aliasing allows for satisfying an import path with a private fork of a package, without having to rewrite all the import statements inside my fork.)

As always, the US is a little behind the times on this too - most credit cards here don't have contactless yet. (I have one that does but its a rarity)
According to 2014 Gallup Crime Poll, 69% of Americans worry about having their credit card info stolen, and 27% have already been hit.

As someone who worked with Google from a customer perspective, they take pride in the fact that their big data (BigTable, BigQuery, DataFlow) is proprietary and superior the their OSS alternatives (I believe they actually are).
I am not saying that they should OSS it, if they build something so awesome that differentiate them, they should know how to monetize it. But at least don't come off with a post like this.
It's not an argument for justifying its value, it's an argument for dismissing devaluation simply based on the hard fork. Network size advantages could end up being temporary, so the remainder of your argument is based on the premise that Bitcoin retains its size advantage.

The remaining question is if you think that the actions of a developer and early-adopter community around one of those technologies in its infancy should affect it's long-term valuation and capability. This seems silly to me. It would be like if Reddit wiped out everyone's karma when there were 100 users and then debating if this meant Reddit was no longer valuable - of course not. In this case it's even stronger, because having large numbers of users implicitly makes these sorts of events more difficult to pull off.

I hate companies that treat their employees like assets. Even Google, they just think because they make work environment fun they have the right to take most of your useful time from you.
