Could you make an example report for some public well known project taken from github. Your current example report just includes a screenshot of some super generic graphs that don't mean anything.

Look at what viva64 is doing to promote their static analysis tool, they analyze open source repos all the time and write about the results: http://www.viva64.com/en/b/0366/ That gives me confidence that the product can actually find issues that might have relevance for me.
Ask HN: Open problems in finance?
Hello everyone,

I've seen people working in finance or interested in finance on this board, so I thought I may ask.

According to you, what are some open problems in finance, old or new? I am especially interested in quantitative finance.

I would ultimately like to come up with a list of them, a little bit like we do in mathematics, physics and computer science.

Thanks and have a great day!
Those who have emailed me--I believe I have sent invites to as many of you as I could.

This very reminiscent of the hype around DNA sequencing.

It turns out that genetics is vastly more complicated than the old "gene = expression" model. By the time you've added epigenetics, environmental control of expression, proteome vs genome, and all kinds of other details, you get something we're barely beginning to understand even now.

"neurons = intelligence" looks like another version of the same thing. My guess is neural nets will turn out to be useful for certain kinds of preprocessing, just as they are in the brain. But GI is going to have to come from something else entirely.
> - Complicated business requirements ("do this every second Tuesday if there is an R in the month, but not if the customer is using the US VAT system and not if the product is a type of cake")

And then you realise there's no consistent definition of "cake" in the system. And when people in the business say "US VAT system" they actually mean "Regulatory system XYZ", not actually anything to do with the US.

Sigh.
I just ran into this today... A site I manage with a Comodo certificate was showing unknown issuer in Firefox and only Firefox, and I've never had it fail before (and we've never had any user reports). Added in the cert chain, error is gone. Dunno if the other browsers had Comodo as trusted or it's common enough that everyone who regularly uses Firefox (I haven't used it in months) has it cached...
Does Apple deliberately slow its old iPhones before a new release? (2014)
Remember the woman who proved that Apple consistently slows down sold iPhones with "updates" right before the launch date of a new model?

No, because that never was a fucking thing.

Seriously, this is supposed to be a community of reasonably well-informed tech-oriented people. Step back for a second, take a deep breath, and think before you spread nonsense like this. Jesus.
The scientific jury is out on whether drunken violence is a genetic trait. Interesting enough idea. "So your father was an alcoholic" is common among alcoholics and their friends looking for explanation.

Violence is also one of those "fallback" mentalities that stupid people embrace when cornered. Genetics aside, stupid people have few resources at their disposal. Violence is there, justified by a century of iconic pop culture that says "when your friend sleeps with your girlfriend, punch him in the head, it's what you must do".

As for convict Australia. Very few Australians today are the decedents of convicts, and very few of those convicts would have been violent.

Australian christians don't really advertise the fact. You won't see an Australian politician saying "God Bless 'X'" at the end of a speech (as appears to be the usual case with US politicians) unless they're speaking to an overtly christian audience. It's fine to be christian in Australia, but proselytising is very frowned upon, and christians who often publicly state their faith are generally seen as 'wowsers' (fun-killers).

Also, MPs are generally voted in by party affiliation, so people vote more for the party rather than the individual person. Anyway, I'm not sure how it's happened, but the power-brokers of both major parties have a greater proportion of staunch christians than the wider population. So, when a party wants to do X or Y, often a bone will need to be tossed to one of these power-brokers to get the numbers.

The drawback to this mode is it looks like ass on anything but a composite display -- which not a lot of people actually hooked up their CGAs to.

There was also a hack to set the display to text mode and reprogram the character height to fit 100 characters vertically on the screen, then use chopped-off block graphics characters to yield, in effect, a 160x100, 16-color, any color any monitor (composite or RGB) pseudo-graphics mode that compared favorably to, say, the 128x48 mono pseudo-graphics mode of the TRS-80. More PC games made use of this mode; one of the more notable recent ones is Paku Paku, a (remarkably good) Pac-Man clone.

Shut the fuck up. You are perfectly welcome to say whatever the fuck you want. If you stay something fucking offensive, then you can fucking expect to be told to shut the fuck up.
there is such a thing as being overly polite, to the point that your speech is just bland platitudes when your main concern is not offending anyone

and guess what? even then, people are going to get offended

there is a limit to how much you can sugarcoat everything you say in public, and i think the us has passed that limit into oversensitive territory

you are right, it is nuanced

my strategy is to say "sorry" when it's due, rather than overthink every minute iota. of course, i'm not running for office and i don't live in the us

>> Sure, you can switch to Google/Android, which as the giant ad company (in other words: personal data hover/mass surveillance company)

While on the iPhone: Do you use Google search ? Do you use Google maps ?

Well, if you do , there's not much sense in hiding from Google. And if you use Android, you could use tools like cyanogen's "privacy guard" to hide your data from all/most app authors , which i don't think you can do in iOS.

Also , unless they target you specifically, so long that you use an alternative keyboard - i don't think Google on Android collects your key press data - so you can use anonymity apps for special circumstances, But i could be wrong about that. Same goes for encryption keys, unless your targeted.
A friend of mine tested this behavior on Cortana shortly after installing Windows 10.

Based on how clever and varied the responses were, all I could figure was that people at Microsoft had spent a lot of time crafting specific responses to all manner of filthy queries.

>Harrison is one of eight writers who creates Cortana's dialogue in the U.S. In addition to writing jokes and coming up with casual banter, her team has to figure out the best way to shut down vulgar conversations.

Mystery solved. I have to admit, eight people sitting in a corporate office discussing the fine details of how their virtual robot responds to suggestive questions is kind of sad, and yet really bizarre.

They could definitely use some better text indexing/relevancy ranking implementations. I had mixed success. I'd recommend lucene or something based on lucene (Solr, ElasticSearch).

Does this mean your fingerprint never leaves the scanners coprocessor and is inaccessible to iOS and the other processors and OSs within the phone?
True, but I was actually referring to them coming as the only interfaces to the iMac. AFAIK the laptops provide builtin HID, so they don't needlessly become a brick from depending on independent battery backed HID devices.
Vancouver, Canada when bars were forced to shut down at 2am, resulted in thousands of drunks pouring into the streets all at once and mass brawling with each other. Laws were changed to allow 4am last call and legal after hours, and the gigantic street brawls disappeared. A barwatch association was started to keep out chronic violent offenders and known gangsters from clubs and bars too which helped.

There's also juiced up goofs here running around one punching random people while their friends film their crime and yell "worldstar" (worldstar hiphop) which is the site where all the recent knockout game idiocy originated.
They should be using replaceState, it looks like they are using pushState instead maybe.
I don't think they are protecting against that scenario so much as not accounting for it. I expect Apple's assumption is that they provide all components for their devices. People who install unauthorised third party components can no longer have those devices serviced by Apple — so it no longer matters to Apple whether those devices are compromised, because they aren't really "Apple" devices at that point anyway.

This botched handling of replaced hardware that hasn't been paired with the Secure Enclave ties into the above. Apple doesn't expect people to replace such hardware through a third-party, so they don't think to engineer their software to fail gracefully when it happens.
Why Costs Matter
Email: [my username here]@ymail.com
The majority of Australians are secular. Take me: I'm from a family that's Church-of-England (C of E). I've been an atheist since at least 10 years old (first strong memory of it), yet the first time I filled out a census form, I ticked C of E because that was my family's religion. These days the religion question on the census form is the only contentious one on it, because of things just like this. Lots of people associate with a given religion but don't really practice it - churches in Australia are fighting falling attendance and graying congregations.

Predicting the markets
Personally I think it's in our fundamental nature to want to explore things in person. I'm never satisfied with pictures of beautiful beaches or landscapes. I have a need to experience them with my own eyes.

I could understand there being no one left who has walked on the moon if we'd been concentrating on the next challenge, i.e Mars. But that's obviously not what happened.

Ultimately I think it would serve as a marker of our collective lack of imagination over the past 50 years to explore, perhaps because the costs weren't palatable relative to any resources we could hope to exploit.

Show HN: Bubblehunt – curated web search
Indeed. License compliance is something very secretive, the old-styled management does not really want to hear they are using GPL. When the company gets acquired is a shock discovering otherwise. Would be better to understand what GPL is all about, rather than hiding. Last year we had a company in Germany that the acquisition failed because they were not respecting the copyleft licenses.

Would appreciate your help. How can we get in contact? There is a contact form on our website if you wish. Thank you! :-)

Hello friends!

Bubblehunt lets people find & share quality resources. We are creating curated web search, where people can choose best results and help others to find it.

Considering extremely high growth of the web, it is becoming harder to find new & quality resources. This is where Bubblehunt comes in. Finding interesting results becomes much easier as they are recommended by people, not dumb machines.

Every user can create a bubble with his favorite resources and provide best results for search queries based on their opinion. We've combined search and human opinions to let people cut through the noise of the web and share the best resources.

Get feedback please)

Yes. The OS can only tell if the fingerprint matched or not. The checking is done solely in the secure enclave. Presumably the OS also gets told which fingerprint matched too?

Their desktop publisher or Tableau Server? Because Tableau Server is the biggest POS I have ever used. Their API is fundamentally broken, their authorization model misses large gaps, and client-integration is seemingly something they never considered.
Yes, at least according to Apple: https://www.apple.com/business/docs/iOS_Security_Guide.pdf (page 7).

"The Secure Enclave is responsible for processing fingerprint data from the Touch ID sensor, determining if there is a match against registered fingerprints, and then enabling access or purchases on behalf of the user. Communication between the processor and the Touch ID sensor takes place over a serial peripheral interface bus. The processor forwards the data to the Secure Enclave but _cannot_ read it".

> Producers have no interest in harming their consumers

If you mean by 'interest' what I think you do, they have an interest only in making money. They have no more interest in NOT harming their consumers than they do in harming their consumers -- and producers of inherently harmful products (cigarettes being the obvious incontestable example) in fact do have an interest in harming their users. But there are PLENTY of producers who have demonstrated an enthusiasm to harming their users, if it sells product.
We could extrapolate this to the music field also.
People buy a high-end watch, like a Rolex. They can repair it if they have then knowledge. The problem is Rolex, and 99 percent of watch manufactures won't sell your, or your Watch Repair person the parts.

You need to send the watch to the factory for service, at factory prices.

So, when you buy a Rolex, your are actually leasing it? You don't truely own it, if you can't get the parts to fix it?

It's just another way to make money.

I didn't think Apple would irritate their customers at this particular point in time?

Author is mixing programming for money and programming for enjoying of algorithms, optimizations and little part of science inside.
Basically, yes. The Secure Enclave is hardware isolated from the rest of the chip.

Apple's own security guide explains it best [1]:

> The Secure Enclave is responsible for processing fingerprint data from the Touch ID sensor, determining if there is a match against registered ngerprints, and then enabling access or purchases on behalf of the user. Communication between the processor and the Touch ID sensor takes place over a serial peripheral interface bus. The processor forwards the data to the Secure Enclave but cannot read it. It’s encrypted and authenticated with a session key that is negotiated using the device’s shared key that is provisioned for the Touch ID sensor and the Secure Enclave. The session key exchange uses AES key wrapping with both sides providing a random key that establishes the session key and uses AES-CCM transport encryption.

Regarding the actual fingerprint storage, it looks like the encryption key is kept in the Secure Enclave and the entire decryption and verification process occurs within the Secure Enclave. However the encrypted data itself may be stored outside the Secure Enclave:

> The raster scan is temporarily stored in encrypted memory within the Secure Enclave while being vectorized for analysis, and then it’s discarded. The analysis utilizes sub-dermal ridge flow angle mapping, which is a lossy process that discards minutia data that would be required to reconstruct the user’s actual fingerprint. The resulting map of nodes is stored without any identity information in an encrypted format that can only be read by the Secure Enclave, and is never sent to Apple or backed up to iCloud or iTunes.

I think IPhone owners intend their device to last longer than the typical Android. Making it harder to repair could undermine that. Apple need to make users believe that an IPhone is not just a disposable thing that lasts for 1 year in order to justify the high price.

No, it doesn't -- It just shows that people google "iPhone slow" more when new models come out / Apple releases major versions.

> For instance, the latest version of the Apple operating system, iOS, is always tailored to the newest device and may therefore not work as efficiently on older models.
