Of course, in both cases it is interior - volume respectively area - and boundary - surface area respectively boundary length - but that is not the same thing as area and volume of a two dimensional object. The analog for Gabriel's horn would be volume and four dimensional hypervolume which is of course also zero because it is a three dimensional object. The paradox goes from interior to boundary, what mkagenius suggested is taking the interior one dimension up.

Given the fact that they misjudged every coup, revolt and civil unrest since the bay of pigs i find it highly doubtful.

The only time the CIA came close to accurately predicting a regime change is when they cause it and even then they can't be sure if they'll still play ball.

Intelligence doesn't work on large scales with many variables this is what makes mass surveillance worthless.

Humint works when you have case officers dedicating their life to study a single tasked asset and even then they are only slightly more accurate than tossing a coin.

Sorry but as an agency that misread the fall of the Soviet Union and more recently the Arab spring I would be keeping my mouth shut in shame.

This isn't to say that the CIA is not relevant and that their officers aren't doing a good job, their crystal balls do need realignment tho.
The best revenge for that is to ace the technical questions, and then ask painfully, acutely relevant questions about the company's financials, their development process, their technical debt, and their competition.

Please note that I have never been called back after doing that.

A genuine technical interview can and will be cut short immediately once it becomes clear that you are not bullshitting on your resume. The person who still asks that 20th question after you have already answered the previous 19 correctly is just being an ass, and playing stupid, time-wasting games with your interview.
Wow. They provide all of the raw log data from the drives[0]. Looks like an interesting source of data for a Kaggle competition.

I found this line intriguing:

> In the wake of the uproar, Facebook updated its approach to Free Basics. It currently allows any third-party organization to offer its services as part of the program, provided that the organization's developers abide by terms that, for example, prohibit the use of high-definition images or video that could consume a great deal of mobile data.

So I took a look at https://developers.facebook.com/docs/internet-org/participat...

These jump out at me:

>Your site(s) may be proxied to make your content available through Free Basics. You can let us know that you want to pull your site(s) from Free Basics at any time, but because we may need to make product and marketing adjustments, we may require 60 days from receipt of your notice to transition gracefully.

>In order for your content to be proxied as described above, your URLs may be re-written and embedded content (like javascript and content originating from another domain) removed. In addition, secure content is not supported and may not load.

Then looking deeper at the technical guidelines: https://developers.facebook.com/docs/internet-org/platform-t...

>HTTPS support

>We encrypt information for Free Basics wherever possible. When people use the Free Basics Android app, their traffic is encrypted end-to-end unless you specify that your service should be HTTP only. For the Free Basics website in a mobile browser, we use a “dual certificate” model to encrypt traffic between a person's device and our servers in both directions. If your server supports HTTPS, we will also encrypt traffic between our servers and yours. Even if your service doesn't yet support HTTPS, where possible we will encrypt that information between our servers and people's devices unless you ask us to not use dual certificate HTTPS. When people use the Free Basics mobile website, information is temporarily decrypted on our secure servers to ensure proper functionality of the services and to avoid unexpected charges to people.

So anybody using 'Free Basics' is giving Facebook full access to their encrypted data. That seems like significantly more than just the 'not using high-definition images or video' claim the article makes.
> Background on wechat http://www.nytimes.com/video/technology/100000004574648/chin.... (video)

Great video.

> Yes, Facebook, Google, Apple, Microsoft, Telegram are working on this. First step was to allow third-party bots, then payments within the messenger (and them taking a cut of the transactions).

Right, but sometimes it seems to me that they are really slow at it. I mean, if they want to become (or want to build) the new Wechat, why are they mantaining (even launching) so many different products with little integration with their own ecosystem? For a company like Facebook, I think that it would take one year at the most to merge Facebook itself, Facebook Messenger and Whatsapp into a all-in-one, superpowered messaging app.

Also, I haven't heard of any startup trying to do something like this. It would be a risky, homerun-or-strike-out swing, true, it would be very improbable to success, ok, but could potentially be the next $100 billion company.
What Would It Take to Turn Red States Blue?
Just about every group of people does that (including programmers). Belonging to a group is one of the basic desires of every human, and one easy way to create a feeling of belonging to one group is to differentiate its members from everyone around.
> The problem is that this is a whole lot of cargo cult.

Please do explain. Where do I use symbolic representations of technology to attempt doomed magic rituals?

As far as the rest of it, everything accumulates cruft. That's why people write new things. And yes, there have been bad decisions. (Just, IMHO, meaningfully fewer than other OSes.) But perhaps I'm blinded by my cargo-cultish ways, can you point to an archaic limitation that you've run in to recently?

I'm ignoring "arbitrariness", as that generally is both highly opinion-driven and generally subject to correcting ignorance of the decision-making process that went it to it. So usually "arbitrary" things are actually one of the other listed categories.
> I have been a big twitter user for years and I am impressed at how unintrusive the change has been. You're going out of your way to dislike a very small design change.

It might seem unintrusive to you because it doesn't interupt your Twitter workflow, it is definitely intrusive to me and is not a "small design change".

I carefully curate the people I follow, roughly for any given day, I can read the tweets in my timeline written on that day - all of them. When twitter's algorithm "surfaces" certain tweets, it removes them from the regular timeline, so if I dismiss their seemingly randomly selected "While you were away", I wont ever see them again! How brain-damaged is this?

The change works fine for people who have more tweets in their timeline than they can read - which is fine if you trust Twitters algorithm to select the ones you find interesting, and I do not. This is the same bullshit that Facebook does with the very stubborn "Top Posts" ordering

The problem with many small business loans is that they need to be guaranteed by "tangible" goods, e.g. land, building, machinery etc.
Banks and other financing providers often also require an appraisal by a 3rd party.

Unless you are buying an already established business it can be very hard to find good financing for things like software since there will be nothing for the bank to repossess and evaluating it's worth might not be easy.
Here’s What You Need to Know About Q3 VC
I've read that when the general public is surveyed on various issues, they turn out to be generally ill-informed. For instance, they think that foreign aid is ten times higher than it is, or that the rich have a far lower proportion of the national wealth than they do.
Not a snark - Over here in HN there were so many people supporting FB and opposing the activists for saying the exact same thing? You said, something is better than nothing. Why doesn't that apply to the US? Is it because if someone is poor philosophical stance doesn't matter?
> Another would be: the ability to manipulate streams (or whatever you'd like to call the content that flows through pipes). As in, replay a stream into some new process without re-executing the original.

My terminal (https://github.com/sedwards2009/extraterm) can more or less do that now:

https://raw.githubusercontent.com/sedwards2009/extraterm/mas...

> Another would be to fold terminal output.

I did have something like that, but had to disable it. That feature will make a reappearance sometime as I want it for things like automatically collapsing command (e.g. compiler) output if terminals successfully. I only need to see the output of failed builds, for example.
I've tried for the past couple of years to get into vim but I can't force myself to remember the odd short cuts I can't seem to ever match up with the action it's doing. I could if I rewrote them butttttt then that blows when I want to jump into a new server without my config. So it's always been nano for one liners and sublime through sftp mounted filesystem.

Totally agree, other thing consider is that if something is done 'free' with government it will always end up being taxed to maintain the infrastructure. So in the end we'll end up paying extra for something that is restricted and only benefits one (or few) entities.

Far better approach would be to remove laws that enforce duopoly, and allow individual cities to provide free (unrestricted) Internet access[1]. Once that's done we can think about providing free (price) service.

Otherwise we will always end up with crappy and expensive service.

[1] still allow private companies to use the infrastructure, but charge them to use it (to cover cost of maintaining it).
Apple's iCloud Keychain has this built-in. Of course, it only works in Safari, and you have to use iCloud...
Who said anything about... feeling "hurt"?
This is why Touch ID & iCloud Keychain are such important advancements. It's not enough to make it possible to securely manage passwords. You also have to make it easy.
Maybe I'm naive for thinking this but shouldn't the government provide some option for those people? I have worked with people who in the early days of the internet only had access at public libraries. It wasn't internet in their homes but it was better than nothing and it was unrestricted. I'd love to see some kind of internet cafe or something strictly for people on welfare or some form of government assistance.

I'm sure there are problems with this idea as I only just thought of it now but it already seems better than letting facebook provide the service.
Yeah, it's weird that offering users the choice of "login by clicking the link we just emailed you" isn't more common.
People said the same thing about Facebook.

There's a tendency to dismiss how important communication is to humans.
Free internet, or just free Facebook (plus a few token sites to look like they're trying)?

Seriously, is there anyone left who isn't fully aware this is just a ploy to create more lock-in and entrenchment, disguised as charity?
This strikes me as the type of app that would be fine in Rails/Django and much, much easier to develop, maintain and enhance.

I'd reserve Node/SPAs for 1) realtime or 2) UI/UX intensive. Landdox seems neither.
CRI is different than temp. A bluish, high-temp lamp and a reddish, low-temp lamp can both have terrible color rendition. Lamps come with a chart, like here:

that graphically shows the color distribution. Temp is where on the visible color spectrum its focus is.

Hey everyone,

I'm very happy to share this mini-project I've been working on with some college friends.

I just graduated in May this year and I've found joining the workforce very exciting. But I thought the traditional approach to employee-boss relations could use a communications upgrade; this is the solution I came up with.

I'm still trying to figure out what would be the most useful for people. What would you like to see? Please check it out and jot down some feedback and ideas - I'll do my best to implement quickly.

Love you all lots.

Let me elaborate. I offer two situations and you can choose which one of them is more plausible.

a) What should we do next? Our cash is burning! Well, lets use countless human hours to make a beautiful font to make the world a better place!

b) How can we reach to more traffic that might be currently not visible to us? Well, maybe we should design a really beautiful font that everyone likes and host it in our server? Sounds like a plan, lets do it!
So what are the implications of an object that breaks that symmetry? Would it be possible to observe an object in different times in the same state, or the same time in different states?

Ouch! Thanks for the report. We'll look into fixing that ASAP.
You're not that far off. The particles aren't really moving, i.e. they are not going from one spatial location to another. What is happening is that they are changing quantum spin states, and the spin states are changing in such a way that it appears that a circular arrangement of atoms is rotating. This is a reflection of the fact that an atom isn't really a thing (there are no "things", i.e. there are no particles) it's just a quantum state, so if you have a quantum system A in state 1 and system B in state 2, and system A transitions to state 2 and system B transitions to state 1 then this end result is indistinguishable from the two systems having swapped locations. We call this "moving" because classical motion is the only mechanism we're familiar with in everyday life that allows two systems to swap locations. But that kind of moving is not what is happening here.

No way. Computer security is like a tax whose returns diminish rapidly.

Once you start prioritizing it with money on security vs product/system engineering, security starts turning into a money monster that delivers nothing. I've seen it happen time and time again.

The asymmetric nature of raising the cost for an attacker is a red herring. You can pat yourself on the back that you've supposedly made it 100x more expensive to attack you, but one operational fuckup pops that fantasy bubble at any time.
It seems you didn't understand my last comment. You're making logical leaps here without connecting any dots. Google's hiring is broken does not follow from Google's UI sucks. You need to put some connecting logic in there if you want to convince anyone that you're even on topic right now.
>Taken to its extreme, we'd end up with a world where we tried to save everything, even every insect, and we'd end up with an unsustainable world or at best a planet-sized zoo where everything was controlled and coddled

We are in the middle of the largest extinction event in this planet's history, and it's our fault as a species. A major causative factor is our dependence on needless animal slaughter to get our jollies. I'd say we are at the opposite extreme to the one you hypothesize, and perhaps some extreme thinking to rectify this is needed. Don't let conciliation become collusion, even rhetorically.

>> Social norms and rules exist everywhere for clothing, especially for women.

In this case it is not a social norm it is a law. For breaking law you can be prosecuted and/or imprisoned, for breaking social norms you cannot. Social norms and laws are two different things, your comparison is extremely misleading.

To make it completely clear why your comparison is misleading look at following example:

In some Muslim countries you can be executed for leaving Islam and it is not a social norm, it is a law and part of criminal code they have.

Now imagine someone from conservative Christian family (let's say in US) changing their religion. They most probably will be judged by their families and some peers, but no one can prosecute them for that.

Enforcing by law certain group or minorities wear certain clothing is a definition of oppression. If there is no choice left, that is an oppression, there is nothing to discuss here really.
> it is crucial that they not forget in an exam that neck pain combined with a headache could be a sign of meningitis, etc.

Why is it crucial if it's just a "5 second google search"? And not every doctor is dealing with serious life threatening illnesses, just like not all developers are working on bootstrapping their uber for cats with Angular 2 and pouchdb.
Correct me if If Im wrong. A time crystal is a cycle at atomic level.

- matter / energy is neither added nor removed to retain shape/movement

- the energy/matter within the "crystal" change state/position in a repeating and/or predictable matter

- pattern retains even when the energy is at extreme lows

This would be analogous to a water cycle. The water changes state in a predictable manner, water heats up (due to the sun) and evaporates. As the molecules get closer to space, the cool and attract each other to form clouds. The clouds hit a maximum and rain occurs flowing back into bodies of water again.

The difference is that the water cycle needs the presence of heat/cooling from external sources while the time crystal can exist at "zero degree" temperatures.

> I don't understand why we can't have both

Perhaps a non-curated Twitter is bad for business? Twitter and the 'Brands' benefit when the ads show up first, and not below the fold, win-win, right?. I suspect curated Twitter has higher engagement as well, so why keep the other option?
Since I haven't seen this argument in the sibling comments: I've met a fellow vegetarian in Australia who still ate kangaroos, which are often killed for population control. Not everyone will agree that that's ethical, but it doesn't necessarily have to do with valuing human life more than animal life. I guess we'd see more of this if we'd let nature recover from human overdevelopment.
I'd say they're definitely corroloated, a really low or high color temperature bulb will go much lower on the CRI since it won't be producing as much of the other end of the spectrum. But a good temperature bulb won't necessarily have a good CRI because a middle temperature bulb doesn't have to produce all the intermediate frequencies that a good CRI bulb will have.

> I buy whole chickens and ... do use every bit of the chicken
> But I'm curious, what use(s) does the blood have?

When I was a kid, my dad used to take me sometimes to a street vendor (this was in a small city in Malaysia, late 60s/early 70s) who ran his business from a bicycle. He had a small gas ring, a crate on the back of the bike with a couple of chickens in it, and some veggies and noodles.

My dad would order a meal and the guy would grab a chicken out of the box, wring its neck, drain the blood into a bucket, burn off the feathers, dismantle the chook and fry it up with mein and veggies. Yum!

But after handing us our food he would boil and eat the then congealed blood (and the other stuff we didn't eat). The food was great (especially since my mum did not approve) but I was always fascinated by this last step.

As I got older I appreciated that he had us pay for the meal and then still got a meal himself out of the deal.
Not really, because optimizing for the wrong thing means you can make changes that hurt everybody and mistakenly think you've helped. Take Reddit's move of banning salary negotiations: control over how the surplus of the employment relationship is broken up was taken completely out of the hands of the employee. All employees (including women) are hurt by this, and yet a blinkered model that sees nothing but gender disparity would celebrate this as a narrowing of a gender gap. There are smart ways to address disparate-impact gender gaps, but insisting that feminism is the only lens through which to view a problem is not one of them.

People encountering this need to name and shame more. This is straight-up using asymmetrical information as a zero-sum weapon. It is hard to find salary information ahead of time, Glassdoor notwithstanding; and it is also hard to know how sleazy they are to employees.

It isn't hard to write a comment about it that will show up in a search engine, and while that is far from perfect, it will allow employees who have freedom of motion to steer clear of slimy firms and those who don't to at least be able to negotiate from a slightly less-weak position.
