>Apple will be the first company to convince the rest of my technophobic family to actually use the technology.

You seem pretty certain of that. Apple has a long list of initiative failures.

Are you overloading the technology side of this? I'm not saying "Apple versus Google Wallet", for instance -- pretty much every Canadian Mastercard, and now many debit card, has NFC on it. I pay at the gas station and the grocery store by moving my card in proximity to a reader. This is ubiquitous. Putting an Apple middleman in the solution seems unnecessary and backwards.

The interesting thing about that insight is that it does seem as though people are trying to copy Apple before they have even entered the arena.

I find this line of thought simply incredible. Wearables have been around for years, and are a simple manifestation of technological refinement in processors, displays, batteries, and wireless technology. It is happening because the technology is there and making it both possible and compelling. Yes, Apple will eventually get in the market, but the notion that everyone else is copying Apple in advance is simply incredible.

I probably give them too much credit and you give them too little - seems like a reasonable balance.

Again, the entire payment industry is moving to NFC. Wearables are becoming technologically possible and powerful. In neither case does Apple deserve any credit at all -- this isn't a case where the middle ground must be right -- and it is rather incredible when they are given any.
In the context of the time, the VAX is the more interactive/flexible/etc. system relative to the 360. It certainly wasn't viewed as a mainframe then. However, from today's vantage point, VAXen--and even the large UNIX servers that followed--seem very mainframe-like compared to volume x86 servers.

I think the counterarguments on Persona are really valuable.

On Facebook, I have 2 major concerns.

1. It's not guaranteed that a user has a Facebook account. I don't mean in general, but similarly as people change their email address when it's full of spam, people shut down Facebook in response to events in their life, like a breakup, to maybe recreate a new one later.

2. I'm absolutely not convinced about the fact that people update their email on Facebook. In our experience with Facebook login, in fact, the email (even when certified by Facebook) is never reliable and it's usually that very old email you had when you signed up to Facebook ages ago. IMHO this is because Facebook is so complete in terms of communication, that you don't actually need an email address for using it.

Some ideas can't be meaningfully tested on a small preliminary scale:

1. Fusion power.

2. A trip to the moon.

3. Marriage.

I doubt that any practical small-scale model would educate us about the full-sized system.
However, these programs all happen within the same school. The trouble in the article is due to a single school with a wide range of options being split into several smaller schools, and the predominantly black school getting worse funding.

Programs such as Honors, AP, electives, etc., are the cheapest way for any student -- regardless of socio-economic background -- to receive high-quality education. Without those programs offered at public schools, I suspect that even more upper-middle class families would transfer to private schools or schools in the suburbs.

Consider sports electives: were they not offered at public schools, the only option would be club programs, often costing thousands per year. At a public school, somewhere around $50 is all that's needed for a year's worth of participation, with coaching that can be comparable to exclusive club teams, and scholarships available for even that amount.

edit: Also, because AP programs are standardized across the country, a student that passes AP Statistics at any school will have the same chance of getting college credit at any school that offers it. This levels the playing field a lot.

It seems like it is desirable for pain killers to leave the pain areas of our brain active, but make the pain less bothersome. If they worked by literally stopping the pain, then we would not notice if we were doing something that was injuring us.

This is dealing with the public school system. It's inherently a society consideration.
With all that data onsite, what are you doing for off-site backups?
It would shock me if there's a working copy of 'rm' allowed anywhere near the Internet Archive. They take this stuff down for compliance, but my dream is that the data lives on, waiting for a saner day when the legal climate for archivists gets a little warmer.

Given that people say this, what do you think they mean by saying it?
A lot of the mineral mining questions revolve around how the economics of heading out a few AU to find stuff compares with heading down a few hundred, or thousand, meters into Earth's crust.

Our understanding of geology now suggests that a great deal of the heavy and rare elements in the Earth's crust were deposited during the late heavy bombardment -- after the Earth's crust had formed (and hence, after the heavy stuff had sunk toward the Earth's mantel and core), but before there was a lot of life. Which means that a large chunk of the asteroid belt is actually scattered across Earth.

Modulo plate tectonics, previous mining, and other activities.

There are arguments that, e.g., pretty much anything you could want to get is obtainable from seawater, modulo energy (and a significant filtration system).

That said, yes, there are some rare minerals which are useful that might be present in high concentrations in specific asteroids, possibly tracing their own origins to very specific conditions of supernovae explosions which both created those specific atoms and grouped them together.

But moving even a few hundred kg of matter, let alone thousands of kg or tons, is a hugely different proposition. That's a lot of energy to expend, and complexity to support.
A good (popular science) read I can recommend is "Influence: The Psychology of Persuasion", which explains some of these behaviours.
'lower-middle class' is the lower part of the middle class. It's not "lower or middle class". Lower-middle, middle-middle, upper-middle. If it was 'lower or middle', that'd make even less sense - university-educated professionals being part of the working class demographic, at a time when university was an oddity rather than the norm?
What's far more interesting (IMHO) is research spending vs disease/condition costs.

For example, diabetes may not be the primary cause of your death, but you (or someone on your behalf) will spend a LOT of money managing the condition & associated complications.

I'm not sure there is actually something in the open source space that is ACID compliant and offers all those features.

Sharding is a problem in Postgres and I am sure they will fix the disconnect between how the data is inserted and how it's read pretty soon.

Automatic failover and datacentre awareness are not typical features in Open Source RDBMS, although you some NOSQL solutions may do this for you.

I'm willing to overlook many weaknesses in PG as we get blistering performance and amazing stability combined with features like hot schema upgrades.

The point is, if twitter feels bad about candidates sharing, they should make a lot more effort to treat candidates with respect. I had a pretty terrible interview experience: I was an internal referral, and despite that, I not only had to sit on recruiter for updates, but after a full day interview they dropped all contact. I'm a big boy: if the answer is no, that's no problem, it's not a fit. But very basic courtesy would have them drop me an email after I gave them a day of my time. I'm not saying that's what happened here, but I've heard plenty of stories similar to mine.

Well, for example, if you compare two persons, one who reads a lot, and one who doesen't read anything, the one that reads will have a much better time processing information in the written form.

It's probably more a thing of which method of "information gathering" are you more used to, and, of course, the notion that "it doesn't change with time" it is kind of stupid, as our mental processes are constantly evolving. But in the end, how used are you to process information in a certain mode will have an impact in the learning process.

>> It would have been fairly trivial for me to go spelunking for people’s credit card information or whatever... But I didn’t. To do that, by definition you have to be willing to become a criminal, and that’s a little bit rare. So I’m not too worried about that.

"In his examples, the cost of annual car ownership remains $12,744 despite the different mileage estimates."

Its actually even worse. The ownership cost lists "Total cost per year (assuming 15,000 miles driven a year)" and that 15K miles is compared to Uber at 5K, 9K, and 13K miles. I am not surprised to discover that it costs more to drive a car 15K miles than 5K miles.

There are other assumption problems. For example like almost all people I can't will myself to generate $2500 of extra marginal after tax revenue while driving (and all the math in the article assumes a zero percent income tax rate, which seems optimistic). Frankly in a taxi I'd probably be about as productive as I am in my car, listening to audiobooks. Parking costs tend to be very binary, if you live and work urban its incredibly expensive and the $1K/yr might only be a fond dream. For me, I'm lucky enough not to live urban so its free. I'm mystified how he's both making car payments on an almost new car and paying hundreds per year for maintenance at the same time. My '14 toyota came with a sales incentive or whatever its called such that I won't be paying for anything but gas until the payments are done after which a couple oil changes a year for the next 15 years aren't going to cost $400/yr. I just paid my registration at $75 which is up from $25 two decades ago ago while he's paying over $350. I do not pay property tax on my car, I don't put it past the more uncivilized areas to try that, but its not an issue for me. Maybe he's breaking down the fraction of gasoline fuel pump cost which is taxes, I could believe the numbers in that case.

The arithmetic in the article doesn't make much sense.
Hi, author here. You're right, of course. Of the 77 210 OK But Gone URLs, 35 had copies in the archive (more had copies than that, but only 35 were from the right year), but 5 (three domains total) had been blocked by a later robots.txt, and 1 had been "excluded" from the Wayback Machine, which I assume is the removal option you mention.

That's 6 redacted URLs of 77, versus 35 good ones. I'm not going to not donate to the Internet Archive and help preserve access to those 35 because of those 6.

EDIT: In the interest of rigor, of the 76 404 Not Found URLs, 4 URLs (three domains) had been blocked by a later robots.txt. 45 had relevant content preserved and accessible. That's 10 redactions total.

Also, when the Internet Archive imports third-party captures, like those from Archive Team, they are included irrespective of the robots.txt from the time of capture, which is then only used to manage display of the content.

It's LOCKSS, lots of copies keeps stuff safe. The Internet Archive isn't the only solution; we need more archives. But it's a start, and getting all the bookmarking services to contribute to it, and to improve and make public their caches would be a great improvement.
Guile LGPL makes it incompatible with commercial games on iOS (because exes are required to be statically linked). However, I think it's one of the best choices on other "more permissive" platforms.
In elementary school, it was always the slow learners who the teachers classified or who self-selected as "kinesthetic learners" when this topic came up: Hands-on teaching was far more patient than lecturing. Lazy students like me were called "visual learners" because we didn't care to bury ourselves in state texts written for 10 year-olds. I sensed that the theory was bunk then, and it's bunk now.

That point is made clear by other comments in this thread treating the existence of these "styles" as a matter of fact.

Differences between students don't prove that learning is constrained to a single sense. It's a bizarre hypothesis and it only serves educators.
"Common" can refer to a lack of refinement, thus rejection by Apple.

"Common" can also refer to "the usual", but according to the numbers, the reasons are all over the place at around 5%.

Glad to see that, however this is not very sophisticated. We used to build houses where the loading walls were thick brick walls, and from what I understand it was mostly given up because of the costly skilled labor requirements. I dream of technology enabling us to construct houses like those again, and of course more beautiful architecture.

I've seen some other brick laying robots, one that built prefab segments where fine distance and rotation of the bricks made a complicated pattern. And there is also those robots that lay brick roads.
First of all - wow, what a talented writer. No wonder her clients have done so well.

Forgery of college admissions essays is rampant not just in China but also in the US (and I suspect in many other places), but actually the problem is really much worse than that. With the boom of the "college consultants" industry, professionals are essentially "forging" entire high school careers on behalf of their clients - telling them what classes to take, which clubs to join, where and how many hours they should volunteer, etc. The end result is that these clients look like amazingly productive students with a superhuman sense of self-initiative, whereas in reality these kids simply followed a script written by some adult their parents paid large sums of money for.
Apple Said to Team with Visa, MasterCard on iPhone Wallet
> Persona assumes something trivially false for most end users

No. No no no no no. No.

This is not "trivially false". Maybe if you said "Persona assumes something which is false for some end users" then you would have a point.

What persona does is being practical. You are identified by an email address which is already the way most people are identified on the web (immediate integration with existing services and no introduction of a new concept such as an "URI identity" a la openid).

Your email address can still be updated as long as you own it and the web app allows it, as you would expect. But using a username instead of an email address would be worse. How many times have I changed my username? I love my current one but it is short and not always available: I sometimes have to use an alternative one. Not to mention the times people outright steal my username; something they cannot do with an email address for obvious reasons.

Please. Persona does have flaws, so don't waste time burning it on a non-issue.
That helps you, but that doesn't help everyone else.

It means they believe in the idea of learning styles and that whatever they're currently experiencing is accounted for by that belief.

As for how I translate that sentence into something useful for me as a teacher, I choose to hear it as: "Nothing in this explanation relates to anything in my picture of the world." It then becomes a problem of understanding the student's prior experience and current picture of the world.

The modality only matters insofar as it establishes congruence with the student's prior experience (IMO).
Is Stache mac only? and is there a way to change iCloud? e.g. I would prefer dropbox.
Excellent question. The way I understand it is that master/slave replication provides eventual consistency by shipping WAL logs to the other node once a WAL log is finalized.

pgpool2 on the other hand provides statement-level consistency, i.e. a statement is only successful when it is committed to all healthy nodes.

I agree that for many use-cases, the built-in master/slave replication is probably good enough, but I wanted to try going all the way… :)
42% of rejections are for "other reason"--wow. No wonder people feel Apple reviews are capricious.
Whitehat is not really looking for extensive security backgrounds for some of their positions. The best way to get in is to show how and why your interested in security. There are many sources to do this. Damn Vulnerable Web App, WebGoat, and Guyere are some available options to see if your really interested in security. I highly reccomend applying for the static code analysis position as a Java programming background would be instrumental in identifying vulnerabilities.

Windows (under Cygwin)

This is usually code for "needs UNIX/POSIX APIs", or its uglier cousin, "uses C99". I wouldn't mind Mingw32, and would mind a little bit Cygwin, but the problem is that for a video game I can't even begin to consider those platforms for Windows. All the official platform SDKs, or the third party ones (think Steam) require the Microsoft compilers and libs.

While I agree with you, I believe there exists an in-between solution.
I think the question is what does portable mean, or is there a better word to use than portable. It clearly doesn't just mean written in C or C++. From the linked page -- "It currently runs under CLisp and SBCL, Clojure, Scheme, Ruby, Python, the JVM and Javascript."

In the sense that they run under CLisp, SBCL, Clojure, Scheme, Ruby, Python, the JVM and Javascript? I can't think of any that are portable in that sense.
Master / slave replication also has a synchronous mode, so lack of consistency isn't an issue. Either way, you still need to do some work on top of replication in order to get automatic failover.
Thank you.

As for a simpler way, I think suitable scripts for recovery should be shipped with pgpool2 as a first step.

A second step would be integrating pgpool2 functionality into PostgreSQL itself. That way, the whole authentication problem would go away, and you would not need to run a separate program. Also, the WAL shipping could be replaced by just letting the non-primary nodes use a replication connection to the primary node directly.

That would not get rid of all of the complexity, but it’d hide a lot more of it from the user :).
A derringer, it's small enough to put anywhere.
"like getting my lawn cut"

This is a particularly bad example, because not only would I have to pay someone to mow my lawn for me, to get my light exercise I'd also have to pay to use someone else's treadmill to get my exercise. This is starting to get expensive and rapidly looking cheaper to just mow my own lawn.

"turning down work" - If I have 8 hrs of work per day and waste 2 hrs of time per day on the internet, I'd rather waste internet time on the couch at home, than try to sneak it in at work because I did some of my work elsewhere.

That's a catastrophe waiting to happen. EMC recommends no more than 8 disks in a parity array group (ZFS recommends no more than 9), specifically because larger arrays cause longer rebuilds, which are more likely to trigger a URE, in which case your SOL.
