"[...] Folha learned that justice in São Bernardo do Campo wants WhatsApp stay out of air in the country due to a criminal investigation.

The authorities investigating the case obtained legal authorization for the WhatsApp broke the confidentiality of data exchanged via investigated by the application, but the company did not release the requested information. The blockade would be a reprisal.

In February, a similar case occurred in Piauí, when a judge also ruled WhatsApp lock in Brazil. The aim was to force the company that owns the application to cooperate with state police investigations related to cases of pedophilia.

The decision was suspended by a judge of Piaui Court after analyzing writ of mandamus filed by the telcos. [...]"

Yeah, we have some public key schemes that are conjectured to be resistant to quantum attacks. This one in particular is fun because of the connection to machine learning. (https://en.wikipedia.org/wiki/Learning_with_errors)

Basically, it uses the result that it should be 'hard' to learn a linear function with sufficient noise rate to create a cryptosystem.
Yes. The shareholders are rent-seeking. They should be taxed as if it was normal income. They don't provide an real value to the company, its output or consumers. For the most part, they are a determent to all outside themselves (specifically their holdings).

Strange article.
What's the license of that?
I'm in the US and my family is in Brazil. I relly on WhatsApp over 3G/4G to comunicante with them as they are usually without access to faster internet (DSL/cable). I read about the blockage a few hours ago and made me concerned because if anything happens that's the most reliable channel I have.

Then I receive a message from my brother saying he was going to the hospital (on WhatsApp, just before they cutted it off). Fortunately he had time to tell me he is fine.

My other brother is in a ship, almost same connectivity problems.

I know that there are workarounds, other applications, vpns, IP masking etc. But WhatsApp is something that my parents and brothers can use.

Ask HN: Late co-founder after a year and small traction
I know it's a common question. But every topic I have seen assumes that funding arrives direclty with traction.

After a year, we have : 50k$ ARR traction for a B2B Saas, with a real disruptive technology, one patent, 4 co-founders (2 tech). No investors yet, but investment might follow in one or two months.

One more engineer wants to join, but we can only pay 1/4 of market salary.
He's a real AAA engineer like me, so I really want him in, but giving equal split with others seems unfair.

I want to propose him 8%, what do you think ?

Thanks !
This only means that the developers have to login with a Google account? Firebase is a Google-owned product, so why would that be a surprise? It doesn't sound like your app's users have to login with Google.

Edit: if you don't want someone telling you how to login, maybe check out Kinto?

> Because if users migrate and stay on Telegram, it could be much harder for Brazilian courts to get records in the future.

Yeah, that's the way that I see it. I don't believe this is the right kind of gambit to be playing. Not only would I expect Telegram to be even more likely than Facebook to tell the judge to shove the subpoena up his arse, he has escalated a war with a company that often is very good at fighting all of its battles on its own terms.

I am now very curious who the subpoena was going after.
Your wording is very interesting on #3, "hit" a pedestrian versus "sacrificing" a driver. I don't think this situation is very likely. A self driving car should be aware of people and would likely be able to compensate without killing the passenger.

If it was a case of hitting a pedestrian versus driving off a cliff I feel like the pedestrian will just be SOL for getting in that situation. Otherwise you could have murder by car relatively easily.

Maybe we could make people register their car settings at the DMV like we do for organ donations. "Would you like to opt-in to the murder-children AI driver, or the martyr driver?"
Seems to me like it might be WhatsApp that's on a power trip. What would an American judge do if WhatsApp were to ignore a lawful subpoena?

It is worth noting that modern cryptography generally considers a system securing only if it takes exponentially longer to crack than it does to encrypt. That is to say, the cryptosystem defines some security parameter y, and legitimate operations can be done in O(y) time, while attacks require O(b^y) for some b>1.

Even quatom computers require superlinear time run Shor's algorithm.
It would be great to see some screenshots of the product (or better yet, a demo account) without having to sign up.

So you seriously are crazy about star wars?
I didn't grow up watching star wars but know about it from Big Bang Theory and all the hype in news / media. I wonder what percentage is hype and what percentage of people seriously are crazy about Star wars as they show in news?

TO be frank, I think its a decent movie but not something to go crazy about.

This is right place to ask I suppose as they portray as if all geeks, tech people love Star Wars.

I would consider that salary as extra income for multiple earners in a household (You wouldn't be able to rent any decent place with that amount per day). Although the cost of living in Juarez is way way below than most places in the US, the cost of utilities in Juarez is unreasonably high. I couldn't find a lot of online resources to support this though. https://goo.gl/beC6LK

I grew up in Juarez and despite my parents making at least ten times that amount between the two of them, I would say we were only considered middle lower class for a household of four people.

The city has grown over the past 30 years considerably due to the manufacturing industry. https://en.wikipedia.org/wiki/Maquiladora

Most of the jobs provided by the maquiladora industry are low wage jobs such as this one that attract a lot of struggling families or individuals from other Mexican states. Some of my old friends still live in Juarez given that they work as industrial engineers and their salary ranges between $30,000 - $40,000 USD. Just enough to buy a 2-3 bedroom home in a decent area of town. This is a comparatively high salary for the region as well.

Can confirm whatsapp is down for some friends in Brazil.

However, the real reason is not for what Techcrunch is saying.

The issue is that WhatsApp didn't want to cooperate with the federal police and release chat information from some criminals. According to some sources there, they followed all due process and WhatsApp ignored.

As a retaliation, to show that WhatsApp has to comply with Brazilian local laws when storing data from Brazilians using the service in Brazil, they banned WhatsApp for 48 hrs.

A lot less alarmist.
I guess so but as a human you will naturally seek new experiences. I don't see why you need to adopt a growth mindset to try to expedite what already happens.

Even if a growth mindset leads you to double the amount of experiences, on a logarithmic scale that is inconsequential.

So you got her number on your cellphone which means you can call and text. You can talk to her, not for free but a few messages should be enough to arrange for another free service.
The whole point of Lexmark operating the plant in Mexico rather than the USA is to save on labor costs. It does not make sense for Lexmark to purchase labor in the USA for over eight times what it would cost if they were to purchase it in Mexico.

Are there any in depth analysis of this idea (short term interest rates have a quick, big effect on the availability of VC capital)?
That article raises an interesting question that I've seen before. Namely: in the event where loss of life is inevitable, who does the car choose to save, and who does it choose to kill? Pedestrians or occupants?

I expect auto insurance companies will have the final decision on this one. They'll provide lower insurance rates for cars that make the correct decisions minimizing total insurance payouts (whatever those happen to be). With lower insurance costs and therefore a lower effective price, sales of that particular brand of self-driving software should increase. Competitors will then rush to do the same.
The alternative is the pursuit of pleasure, because why not enjoy it rather than suffer if you're just going to die?
I have made a comment or two recently about how unlikely AGI/superintelligence is in the next 50+ years. Those comments received a net positive response. I don't think HN is as biased toward AGI as you might think. Then again automation in labor tasks doesn't require AGI --just specialized programs that work well. Advanced automation is very likely to have an impact in the next 5-10 years.
The central idea seems so important, with so much benefit to education if it were true, that it would justify a large scale rigorous experiment [ just as a new kind of promising medicine would be trialed over a wide sample ]

Never realized that the political scene in Brazil was as crazy as the article portrays. Makes the US election campaigns look downright tame. As bizarre as some candidates' ideas seem to be, hard to imagine how judges or US congress would get away with attempting the same things.

If provisions like those in the article persist, predictably the predominantly young users of social media will protest loudly, I would think the resulting unrest would be too big a liability for the judges and politicians.

A while back I knew a guy who worked for a US company involved with setting up inventory and telecommunications software for businesses. Having traveled to Brazil to assist with installing the systems, he described the extremely convoluted regulatory environment down there, and how difficult that made it to get anything done.

While the whole affair is hard to understand, the basis for picking on particular targets (e.g., WhatsApp) doesn't make sense. Unless all such services are banned it only punishes the particular providers for no good cause. Speculating out loud about their target selection is unproductive, but possibly someone has more actual info about it.

So I guess like politics anywhere, what they do know well is how to shoot themselves in the foot. Until it's realized what they've done it will cause a lot of trouble for legitimate enterprises, let alone the massive population so negatively affected.

Another way to explain this is that quantum computing would be the perfect answer to some extremely-naive kinds of cryptography, reducing the decryption time-complexity quite harshly (though not all the way to O(N) as one might expect)—but modern, practical cryptography does things fairly differently than spherical-cow cryptography.

For example, if cryptography basically consisted of taking a set of plaintext "blocks" and a key, permuting the key separately and deterministically for each block in O(1) time, expanding the key into a one-time pad again in O(1) time, and XORing each block with its respective pad—then you could use a quantum computer to quickly search the keyspace for a key that decrypts the blocks into something sensible according to some heuristic. You can make a quantum algorithm that "searches" a static keyspace, given that you can map a particular ciphertext block to particular plaintext block in O(1) time—this mapping effectively becomes a "projection" of the keyspace, and the quantum computer searches that.

The problem with this approach is that, in reality, subkeys in a "stream" aren't generated independently per-block (as happens in the much-derided "ECB mode" of block ciphers), but rather are generated serially by feeding in the previous subkey in a chained operation; and that each cipherblock is then created by "expanding" the subkey through a CSPRNG, which itself uses iterated hashing.

You can't make a quantum algorithm that searches a keyspace, given an encryption algorithm that is defined recursively or "statefully" on its input stream. There's no such thing as a "quantum for-loop" that magically makes an O(N)-step process into a single linear projection of the keyspace—and without this, there's nothing to usefully search through.

tldr; This is about licensing of the code that users post on their Q/A, NOT the source code that powers SO. Further, under new terms, all code posted on SO will be MIT license with an option to "NOT include the MIT terms with your project and only attribute to the author IF requested" - So, essentially boils down to public domain with moral rights to the author.
What a load of lazy nonsense, it's the startup equivalent to the "never do this" chum buckets at the bottom of penny ante media websites. There is no formula for successful hires, especially in tech, especially in startups.

A "founder" who sells 6 startups at age 30 and makes a bundle off of each is a raging success, but a potential employee who climbs the ladder and lands a better job at 6 different companies by age 30 is "suspicious". I'm surprised the author hasn't collapsed under the weight of the cognitive dissonance.
Like what? That would make for interesting discussion. Unfortunately, throwing money at the generational poor won't change their culture.

How does society ensure that parents are providing proper mental stimulation for their growing children? Crafts, puzzles and books can be incredibly cheap. But even if these are given away for free will they be accepted or shunned for TV and video games?

How does a society fix bad parenting? There's parental rights involved that limit how far that can go. For example, we can't declare a parent unfit just because they're poor, and we can't force them to raise their children in better ways.

How does a society intercept and prevent parents from imprinting generational poverty culture on their children? This is a problem for children of other income brackets as well where the parents are absent and don't teach their children how to be smart, responsible adults. I knew quite a few people in college who were born with a silver spoon in their mouths that are now in poverty once their parents cut them off and they weren't taught how to make it on their own.
Amazed at the stability. Is it typical for drones of this caliber? I would think weather would have knocked them off course at the very least.
It also says that, in a contained but nontrivial aspect of life, Brazil has given up its sovereignty to WhatsApp (and by transitive ownership, Facebook, and by transitive law enforcement, USA/NSA). And for various reasons, it is applying for a similar serf status at Telegram as we speak.

Think about it: Mark Zuckerberg can task his employees with an elaborate "find and replace" on all brazillian texts, replacing e.g. "sugar" with "salt", and it will just happen. Think that's improbable? Facebook has been toying with your emotions before [0]

Here is the mechanism that will fully elaborate brc's point.

Elderly consume more than they produce. The young produce more than they consume to save for retirement.

A lowering of interest temporarily induces additional borrowings which will be invested in capital in the short run. Inefficient companies that were going to go bankrupt and release their physical capital for more efficient use, will be kept alive, staving off job losses.

In the long run, low interest reduce elderly's income on their savings. Reducing elder's income reduces demand for the goods the young produce. Since the young cannot produce at a loss, they produce less and have less income to save with. The causes reduced savings, which in turn means reduced investment, and thus even less spending, less income, which means deflation. This deflation is further enhanced from the increased supply caused by the increased investment in capital when interest was first lowered. And if you keep lending to companies at near zero interest rate with money from nowhere, increasing inefficiency in capital means lower yields in stock markets general, also lowering income in the long run, and lower job growth.

The Fisher equation[1]: Nominal interest rate = Real interest rate + Inflation.

The initial thrust of lowering interest will boost the economy temporarily. Keep down nominal interest rate long enough, and the economists will get the deflation they so dread.

Now you know why the EU and the U.S. has trouble with lack of inflation "even though" interest rate is so low for the past so many years.

Actually, code is as error prone as the engineering process that creates it. You can have a process that takes risky, error prone engineers and creates very safe output. Airlines do this all the time.

A by-product of this might be an airline level of safety and after the accident investigation. There certainly would be the financial benefit for it. Once the autonomous car comes it will be safer than humans to start with and only become safer and safer with time. It might get to the point where we regularly travel at 90+ mph on the highway with barely a care in the world.

Your options are:
1. Stick to the same source, crawl the pages for updates

2. Figure out the topics of the story, and do a sort of "Google Alerts" for those topic, and filter to things that are relevant.

3. Go user generated. You submit a story you're interested in, other users can look through lists of "un-updated" stories, and if they find an update they can get "points", since everybody loves internet points.

Good luck, if anyone manages to do it, let me know, my dad would love to use it.
> Given their abundance, it is remarkable that there is no hint of their existence in the records of the Christian kingdoms of the time. In combination with the impractical layout of the tunnels this has engendered the suspicion that the tunnels were used for a non-Christian cult that developed in the 10th century and later disappeared. In that case the slip passages might be a ritual element to slip off diseases and guilts (rebirth).

Forgive me, because I know little about how these types of things are determined, but I'm curious how anthropologists/archaeologists/etc. arrive at these types of conclusions. Is there evidence of a cult that existed around that time that thought this way, or is this just an educated guess based upon society at the time?

So rather than wait for >10 years for green card, I moved back and did what i always wanted to do - Start a startup. Starting my own company back India is definitely better time spent than twiddling my thumbs and waiting for the green card to come through.
