Apple to Start Making iPhones in India Over Next Two Months
i'm a huge regex nerd (see: regexpixie.com). But this is a classic example of people trying to be clever instead of clear. And I would always much prefer to read clear code than clever code.

Regexes are declarative and they're really good a narrow set of features - namely, finding text that matches a pattern. When I see someone using negative/positive lookaheads, or trying to match a valid date with a regex, I see someone who is furiously pounding a nail with the fat end of a screwdriver.

If you want to keep things simple with regular expressions:

* Be liberal with what your pattern matches and use a normal programming language for your complicated conditional logic to filter out crap you don't want

* Don't be afraid to break up the search with multiple regular expressions

* Ignore pattern whitespace and use it to visually break up your pattern. Nobody would agree to debug javascript that has been minimized, yet people do this all the time with regex

* For the love of all that is holy, USE NAMED GROUPS. It is a fantastic way to document your intent.

This is confusing: \d{1,2}/\d{1,2}/(\d{4}|\d{2})

This is not:

(?<day>\d{1,2})

/

(?<month>\d{1,2})

/

(?<year>\d{4}|\d{2})
Apple's attitude to third party devs aside the system is broken for professional work from the get go. It's entirely locked down and siloed.

I recently had to fix some issues with my parents iPad and it was a hell of a eye opener into why it's a terrible idea to rely on these devices at all.

So my mother does painting as a hobby and recently has got into using Brushes (2010 Apple Award Winner), at some point her iPad decided to update itself to iOS 10 (note you cannot disable updates anymore, only postpone them) and was a bit surprised she could no longer open any of the paintings she'd made in the app over the last 3 years. I tried to update the app, it's the latest version

I tried to open them > crash, tried to email them to myself > crash, set up a dropbox account to sync them off the device > crash.

I look online and find this app despite having won awards and being used by famous artist David Hockney is no longer updated, but good news it's open source so someone else has taken up the job of updating it to run on """modern""" iOS, so I install Brushes Redux, it works but none of her paintings are in it. So 3 years of work is on the device, we have a version of the app that should be able to open that work, but we can't because all files are siloed within app.

Long story short after 5 hours of trying to sort this out I finally used a very dodgy looking app to pull the hidden files out of the old brushes app and into the new one. Let's just hope Hockney manages to figure this out too or millions of pounds worth of artwork might be lost for good.

I use software in my day to day work way older than this brushes app but this scenario will never be a problem in my work because my OS isn't locked down, siloed and can disable updates.

If you read upthread it was explained the final fall of the Roman Empire could be attributed to treating their refugees like dirt and lying to them.

Also, I'm currently in US and I don't feel my way of life is being destroyed by Muslim people. I think anti-Muslim sentiment is more of a negative influence on my life, as I work in academia and have had to deal with co workers and students being unable to continue research due to the immigration ban amongst other things. Also the whole "an Indian engineer was shot and killed by a white man for looking like a Muslim" that occurred recently has put fear into a lot of my peers, a significant chunk of them Indian or Pakistani. It's really kind of made my workplace tense and afraid whenever current events and the current political administration are brought up.

Most all major acts of terror in the USA have been by white people. I believe the vast majority have been by whites in the USA. In the last 10 years included. I don't see where you're getting the "major terror attacks" thing. In USA we had a stint where white men were shooting up schools and killing children practically every month. I'm pretty sure white people have committed more acts of mass killing in the USA than Islamic terrorists. Where is the pattern recognition here?

Anti-Islamic sentiment has long been regarded as applying to a lot more than Islamic people. Sikhs, Indians, anyone that looks "brown" enough gets the anti-Islamic sentiment. I've even had an anti-Islamic person tell me that there's a rule in the Quran that allows an Islamic person to lie about being Islamic if they feel they are in danger, and therefore you can never trust anyone who looks Islamic, because they could be lying about their belief in Islam. I'm not saying you personally agree with this, but these are also other anti-Islamic sentiments I've discussed with my peers. They seem to trend towards racism.

The problem being that as soon as you start bringing the left/right dichotomy into the picture, you've lost all hope of having a sensible argument or even an intelligent discussion.

I mean, it's not like it's all that difficult to rephrase the question in a way to be less thought-terminating (and this is literally one substitution, you can imagine even more eloquent ways of phrasing it):

> "Is the problem "single mothers" or is it the people who conspire to create, perpetuate, and steadily increase economic inequality?"

I want to believe that most people KNOW this, and it's merely "virtue signaling" as another poster noted. An easy way to vent frustration, maybe. But it's not a question that asks for sensible discussion. It's a "when did you stop hitting your wife?" type of question - one that insults the very people you really want to answer the question. How do you expect to have a reasonable discussion like that?

I worked on a project that used "regular old URL" just like you suggest, for contract and service identifiers, which needed to be human read/write/generatable

Tag URIs would have been better because:

a) not everyone owns a domain, but tags allow email address as authority

b) it's confusing to many people to overload http URIs this way

c) as a contract identifier the URI doesn't need to point to anything, but this creates cognitive dissonance — this is probably part of b)

d) too damn long — tag URIs might suffer from this too. We were using these all over the place and there's no good way to truncate them

You propose:

(?=((?!exp).)*$)

I don't believe you're right, but can't be sure, because you haven't given a method of translating an arbitrary regular expression containing a negation (?~E) into one without.

For example, how would you translate:

(?~exp)a.*

which asks for "anything not exp, then an `a`, then anything"?

(?=((?!exp).)*$).*a.*

is wrong, since it doesn't match "aexp".

(?=((?!exp).)*$)a.*

is also wrong, for the same reason.

(?=((?!exp).)*a)a.*

is wrong, because it doesn't match "expba".

I fully agree that facts must supersede feelings, but that doesn't mean that one has to be a policy expert or economist -- that's yet another rigging of the system.

You don't have to have studied very specific disciplines to be suspicous about the fact that your parents went casually to work at offices without ever "disrupting markets" or "moving forward and breaking things" and yet they had 2 cars, villa at the sea, and 2 apartments. How? By showing up at work and working times less than you or me.

This is a great bill. It creates a slight public subsidy for broadband, but the total amount of subsidy is minimized by tying it to digging that's already going to be done. This should be extended to power line and water pipe construction. No reason you can't put in some dark fiber while you've got someone up there hanging new power line (which I imagine is way more expensive).

Most importantly, it minimizes market distortion. Inatead of making it more expensive to deploy broadband (which is the ironic side effect of many broadband deployment policies), it makes it cheaper for competitors to enter the market.

The fact that to most of us this isn't "news" suggests there is a very deep and intangible flaw in our society. For the people paying attention, government hacking is the number one flaw in our democracy. It suggests that we aren't in a democracy at all.

Right now I am sitting in a classroom with 63 other students. Half of them are "taking notes" on their laptops while the other half are using a notebook or sleeping. Each student has a cell phone, each cell phone has a microphone and two cameras. In this room there are 63 microphones, 126 cameras, and approximately 30 open laptops, each with their own camera and microphone.

The CIA is collecting data from these devices as I am writing this. But it is hard to find anyone that actually cares. The narrative that is being pushed by traditional media and social media is that this is standard.

Just ordinary national security. To keep us safe.

"Though weirdly in modern American politics, there's some degree of inversion there, with the "coastal liberal elites" voting for "socialist" healthcare and the unemployed coal miner with black lung disease voting against it."

This is not the paradox that people think it is.

If you're a coastal, progressive elite, you've already gone "all in" on an urban, socialized, statist (for good or for bad) social arrangement. You've shifted towards a pole and you might as well keep doubling down on those strategies/policies.

But if you're rural (or, as is the case with most of red-state US, sort-of-semi-rural), you're not down that path at all.

There are costs as well as benefits to social benefits and welfare programs. Many of those costs may be intangible, but they are costs nonetheless. Consider: what if a very large portion of your self esteem and "face" was tied to being self-sufficient in certain realms ?

And so therefore, if you're not already at the urban-progressive-socialized pole of attraction, it makes sense that people resist the costs (and the benefits) of going down that road.
We'll see how this plays out. I got an invitation email from Medium to submit a pitch and compensation amount. I've received an automated response regarding the submission, in that they have a lot to go through and will only contact those they are interested in, that sort of thing.

I like the platform and how dynamic it is in a multimedia sense, yet the 'anchor' is still the written word.

This is a new time for media enterprises. Even the NYT is getting a refresh - according to Taibbi at Rolling Stone, 132,000 subscriptions in the first 18 days following the election.

There is a craving for better signal-to-noise voices. The pendulum has swung - obviously - in an extremist direction, and it will take someone of incredible merit and stature to rise above and simply, deftly, and beautifully dispatch with such rhetoric on a daily basis.

I'm pretty optimistic in Medium's chances to cultivate a new arena. Heck, even BuzzFeed is getting into the serious journalism arena.

Crushh – Find out if your crush likes you
The author of the article is a professor of economics but doesn't state the true cause of rising housing costs: Market inefficiencies (or market failures) caused by politically induced market scarcity restrictions called "rent-seeking" which benefits landowners such as President Trump over people who rent or are purchasing housing.

Rent-seeking was first illustrated by David Ricardo in the mid-19th century (IIRC) and surprising that the author did not cite the true reasons for the rising housing costs.

Harvard Economist Edward Glaeser and Economist and Financial Times writer Tim Harford among many others writes about this.

Remember, rising prices come from scarcity. Eliminate the scarcity and your eliminate the high prices. Reverse the zoning density restrictions and you get lower prices.
How  to Effectively Lead Remote Teams
Does your crush like you back? How do some of your friends, or even family members, feel about you? Need help analyzing your texting relationships?

Crushh is the app that lets you know how the people you text feel about you...secretly. We only give you this information, so the other person will not know you're using the app. Imagine Crushh as the friend you hand your phone to for their honest, unbiased view of a text conversation. We give you that perspective, but based on data and algorithms that decipher and interpret the words and patterns in the conversations.

The app will analyze the data already on your phone so there's no additional step to input information. Although we collect the text message and call data on your phone, your privacy is our highest concern. No one can read your texts.

Simply download and install, and select the contact you want analyzed. Within seconds, you’ll get a score indicating how much that person likes you, along with measures of engagement and interest. You’ll even be able to see how that score has changed over time and pinpoint exact days when the relationship changes. If we're wrong (which may happen at first), you'll have the option to give us feedback so we can increase accuracy over time.

Because if you're growing organically some VC funded competitor is going to try to grow exponentially, and swallow you up or put you out of business. There's no middle ground because all that looks like to people trying to get a return on their investment is that you aren't trying hard enough. That either means they push you harder, or they fund a competitor if you aren't beholden to them.
