Hi guys! My name is Wojciech Danilo and I'm one of the founders of Luna. The timing for this news is a little unfortunate, because we are just before releasing Luna as an Open Source project! However, it's great time to answer some questions and give you a short update what has happened for the last couple months:

1. We've raised a seed round of $1M, so we can safely focus on product development and shortly on community building!
2. We've improved our core technologies to be much more robust, open and extensible, including:

- We've re-written our graphical interface to be much more open and extensible (it was previously running on WebGL and now we base just on HTML, so it will be possible to attach any HTML-compatible controls / visualisations directly to nodes)
- We've implemented new, better type inferencer and updated Luna compiler in many ways.
- And much much more, but I don't want to uncover everything before the release, especially when it's around the corner :)

I would love to answer your questions, so If you've got any, just post it here and I'll do my best to cover it. Don't forget to singup for the list at http://luna-lang.org. We'd love to collaborate with you during the upcoming release! :)

Cheers,
Wojciech
This is similar to Knime [0], which lets you build "workflows" visually, and allow you to write custom blocks with Python or Java. The main difference seems that you can represent the whole workflow in a human-readable (and writable) format.

That article is somewhat confusing.

... And then they never go into that more. Why is that not an acceptable reason to not hire someone?

As you can see, the actual lifetime is projected to be a lot more than 8 years for a typical car.

Also, please don't post insults like "Nice spin" on Hacker News. Data works a lot better.
Then read "The Cellular Automaton Interpretation of Quantum Mechanics" by Gerard 't Hooft (https://en.wikipedia.org/wiki/Gerard_%27t_Hooft), which tries to formulate a superdeterministic version of quantum mechanics based on cellular automata (i.e. much more discrete):

Quality education and healthcare do not have economies of scale, so countries should be easily comparable.

It's unlikely that as a country grows, the optimal class size increases or that a doctor is somehow able to treat a patient nx times faster than in a smaller country. Doesn't make sense on the most basic level.

Defense does...sort of, but the US DoD is such a unique and unprecedented beast in human history that it's hard to make hard conclusions about it with n=1.

a caveat to healthcare is that medical R&D probably does have economies of scale, but not routine treatments and healthcare.
People misunderstand Uber's motives. They are not slimy.
Quite the opposite: they are a public good. The company is the front end for a giant charitable effort by venture capitalists. They are pouring money into uber, to help it drive down the costs of urban transportation, enabling people in cities to have more money available for necessities like rent, diapers, and food.

I didn't know that there were mandated limits on processing power. Do you have any more info on this?

What processing are there limits on? Is it just the wind tunnel equivalence (Were there limits on wind tunnel time back in the day?)? Is it just pre-manufacturing simulations or do they limit the sort race simulations that we're talking about here?

Regardless of whether anyone else did it, do you think these are examples of Uber making the world a better place and breaking rules that shouldn't exist?
The difference is ride sharing is when the driver was going to do the ride anyway, and the passengers are just sharing the ride, hence the name. It's historically been mildly popular, for instance, on weekends and other breaks with trips originating at and returning to college campuses.

Of course, none of the big “ride sharing companies” have anything to do with actual ride sharing.
What is your business model?
>The problem with "significantly over-pay" is that you end up with incentives for people to quit other low paying jobs and switch, which will force those employers to either significantly increase wages to match or more likely, automate the job.

I see absolutely nothing wrong here. What's the problem?
The intro video mentions Java, C, and C++.
Since I haven't been in a K-12 math classroom in about 10 years (contemplated becoming a teacher and visited some friends' classes), what's the gobbledygook we're teaching kids these days? I don't recall any gobbledygook from my years in K-12 education (excepting an awful, awful long-term substitute teacher). Arithmetic and algebra (K-8, basically), geometry, trig, and calc were all practical and applied (the latter two in advanced science courses and work rather than daily life).

I think more probability and statistics courses would be easily justified. Regarding computational thinking, math in the K-12 level is computational thinking more than it's based on proof construction. Computational thinking should be added as a subset of the math and science courses. I think it helped many of my college classmates who weren't in CS to understand computational thinking when we ran simulations using matlab of experiments, or in the reverse used it to process our results.

Yep. I hate this compelled tipping we've got everywhere these days. How long until we're asked if we want to tip at the grocery store, or the gas pump?

Even if the cashier (at, say, retail location) says "feel free not to tip" that does little to make me feel less shamed.

Tipping should be for exemplary service, not routine service. That's why adding it to Uber is stupid: I expect fast pickup, nice drivers, and safe delivery to my destination for the price I pay. If I don't tip will it be an extra long drive? An extra long wait? Will I lose a limb along the way?

It'd be like being asked to tip at a fast food restaurant: I don't expect to have to tip to get my food fast, that's just part of the value proposition.

Uber just keeps driving nails in their own coffin!
No, or at least not as originally propounded.

The point of the butterfly effect is that every small input magnifies so much in a chaotic system over time that you won't be able to predict it correctly if you miss any detail, even one so insignificant as a single flap of a single butterfly's wings.

The moral being that a chaotic system is fundamentally unpredictable in detail, and can only be predictable in averages and aggregates. (So we can predict climate, but not weather.)
Sorry, but there are still inaccuracies in your comments.

Hyperscan doesn't have a JIT. PCRE2 and sregex are not the only ones with a JIT. For example, PyPy's regex engine is JITed and so is v8's. The existence of Hyperscan (and Rust's regex engine) should show that a JIT is not necessary for high performance.

Constructive mathematicians definitely do believe the reals exist and are uncountable. Not all reals are computable or definable. The set of computable reals is countable. There are different varieties of constructive mathematics. A very large majority of constructive mathematicians believe the reals are uncountable. In intuitionistic mathematics the reals are uncountable.

In some constructive versions of math you get weird things like there being an injection from R to N but there not being a bijection due to diagonalization.

I think you are confusing computable/nameable with constructive as that term is used by most mathematicians.

Note that Chaitan's Constant is not computable.

Have a series of summits to discuss culture. Have focus group meetings with everyone from execs to drivers in the room. Hire a new HR director or put someone into place that can overhaul the reporting system. Do sensitivity trainings, retreats, summits, whatever. This directly a addresses the harassment issue. I don't know much about how harassment reporting works, but there has to be some sort of standard that HR professionals are trained in.

Then I would raise fares and remove tipping. Improve the customer experience.

Finally I would hire more local employees to monitor on-the-ground operations like drivers, cars, and service. Set up a mentoring program to help drivers get started and stay on. No one is fooling anyone by treating them like contractors. For customers, drivers are the face of the company. I'm brought to mind of Disney's "cast member" concept. The lowest employees on the totem pole are the ones your customers see the most, invest in them.

IANAL but it seems like this would kill the case that drivers are "independent contractors" and that would have a huge impact on their cost structure.
Both ST:TNG and B5 took their original source material and brought it down to SD and added the visual effects in at that level. So, we still had higher resolution original source material, but it had no effects in it. And these shows have a LOT of effects. When it came time to release ST:TNG on Blu-Ray, they had to recreate the effects and apply them back to the original material, which was a large and costly undertaking. Since it didn't make enough money, they have no plans to do this things like ST:DS9, unfortunately.
What kind of plots can you make with this? This has real potential in the big-data and scientific fields. Plotting is hard and if you can easily tie together many data sources and models that are popular onto time series and geospatial plots this will be a winning combo go scientists.
It seems strange to me for the author to write that, and then to end with:

> But I do believe that it is time to make [mathematics] a true science.

Surely any 'true science' has a dichotomy between conjecture or hypothesis, and theorem or accepted fact?

Hi! I'd be happy to cover any of the fundamental questions you are refering too. I was trying to cover them last time, but if there is something uncovered, I'd be more than happy to fix it :) Would you be so nice and specify what are your concerns?

Regarding the questions, I've just put some small summary of updates on the top level of this thread. Regarding real world applications, Luna will be well suited (but not limiting to) to interactive data science, creating custom data visualisations, microservices management, rapid prototyping of any data processing networks (inlcuding IOT systems) and of course graphics or sound processing.
Here is the problem, because there is only one of two arguments you can make.

1. He was so inept as CEO that he was unaware of all (it is a big list) the shady things putting the company he was the majority share holder of at risk that he deserves to be fired and have it crash and burn.

2. He was aware of the bulk of the shady things, that makes him complicit. As an endorser of Ubers lager pattern of behavior and over all toxic culture, he deserves to be fired.

There is NO way to defend Kalanick without sounding like a shill.

Google information. Shortly thereafter, Mr. Levandowski communicated to Uber
that he had destroyed the discs"

I think it's not about re-broadcasting, but about providing the show in a better format. The originals were shot on 35mm film, and then that was "mixed down" with the visual effects to some lower-definition format (maybe SVHS, but I'm just guessing) and the result sent to TV stations to broadcast.

To make a high-definition format (e.g., blu-ray or HD streaming) they'd go back to the original 35mm masters and re-convert them. But then all of the visual effects had to be re-added on top.

There are various articles that mention quality issues with the remastering:

A Growing Cancer: Forbes’ Midas List
Stop Copying and Pasting While Presenting – ScriptedPresenter
It's these types of comments that demonstrate how ignorant the doomsayers are about Uber's business. The doomsayers start with their desired failure outcome and work their way back to the present instead of seeing the myriad ways they could not be more wrong.

In this case, Uber is an international business that operates in the northern and southern hemisphere and many places with other relevant weather patterns like rainy seasons and dry seasons. The seasonality at this point is likely almost entirely smoothed out by the sheer number of places they operate in globally. The US market might be larger and more mature, but many international markets have largely caught up now.
I'm not sure about Babylon 5, but I believe TNG was shot on film, but the effects were all done at broadcast resolution due to cost. This meant that when they released the DVD version, it was not difficult to create HD versions of all the "real" footage, but the effects were all in standard definition, so they looked awful. For the Blu-ray remaster, I believe they redid all the effects with modern CG, so they no longer look like crap.
Product Management and the Challenge of Globalization
I've recently started investigating the options for moving from the US to Canada as a current H1B holder, and what you are claiming couldn't be further from my experience at all.

The Canadian visa system for skilled workers is so much simpler than the USA I almost couldn't believe it. No quotas, entirely points based, your score is easy to calculate and the minimum number of points needed published at regular intervals, much more personal control and far fewer vexing employer sponsorship issues as is so frequently the case with US green cards. It's almost meritocratic...

The French requirement for permanent residency visas generally only applies in certain provinces as well, especially the eastern ones like Quebec. Not speaking French isn't an issue for visas to work in most major cities in Canada, including Vancouver, assuming you speak English, aren't ancient (age is a factor in scoring), have a reasonable degree and a small amount of savings.
No, I also suspect it shouldn't use nearly that much CPU time. I just wanted to make sure it was high enough that I wasn't underestimating it.

These two specifications are for different use-case. Netflix's is about having consistent quality of ordered works and preserving the ability to do lossless-ish conversions, while BBC's is technical specification of what can be broadcast without excessive additional conversion steps.

How can a government force a researcher to make their results public?

Isn't that reaching too far?

I feel there is a reasonable, decent case for private, for-profit scientific research, is there not?
Maybe I don't understand the charts and the article you linked to but it says that:

"Uber passengers were paying only 41% of the actual cost of their trips; Uber was using these massive subsidies to undercut the fares and provide more capacity than the competitors who had to cover 100% of their costs out of passenger fares."

To me that sounds like selling rides at a loss.

The media wants to tell any story that gets attention. Complaining about the media is a distraction, but at least here there's the amusement of accusing the media of conspiring to tell the story of a conspiracy that doesn't exist.

The contempt charge is less material to the story you are interested in talking about, but looks rather important to me. And we don't have proof of anything - Maybe Kalanick got cold feet partway through. We don't yet have sufficient detail to know what this means.

Although now that you shine a light on this, it does seem to demonstrate is that Kalanick went ahead with a key hire who was anteing stolen IP. Call that what you will, but I wouldn't hire a janitor who did that, nor would knowingly I work for anyone who would do that. And it is also further recklessness - even putting aside ethics and legality, who is to say Levandowski wouldn't do the same thing to Uber if he got a better offer?

From a language-user point of view, Trigraphs are an arcane but irrelevant feature, insofar as ignoring them or even being unaware of them won't cause any harm. [I only happen to know what a trigraph is because I read a lot and have a brain that randomly holds on to pieces of information with an iron grip.]

Never having written a compiler, I can only imagine how tedious supporting those must have been; and I would be willing to bet that trigraphs weren't even used much, because, among other reasons, hardly anyone knew of them, so it must have been really frustrating for people to support them. An Exercise in futility.
trusted boot and TPMs with remote attestation exist precisely to ensure that physical access does not mean game over. It's all there, people just need to make use of it in their systems.

The limit for the last couple of years has been 25 Teraflops at 64-bit precision.

You are presuming that Google followed the proper legal process based on what? Did you even bother doing the research?

http://gizmodo.com/former-google-engineer-blasts-companys-hr...

According to multiple sources and internal notes read to me, after discussing the claims of an alleged encounter between Singhal and a female employee first with former Google HR head Laszlo Bock and also Google CEO Sundar Pichai in late 2015, he denied those claims at the time. He also apparently stated a number of times that there were two sides to every story.

A former Google employee I spoke to has described the search giant’s HR as “a nasty mess.” They are not alone. Monday afternoon, former Google engineer Kelly Ellis shared some of her own experiences with at the company in light of the news surrounding Singhal’s departure. Ellis previously tweeted about sexual harassment she faced at Google back in 2015.

Sounds eerily familiar. My point being the exact same as what I said. Uber isn't right for letting this happen, but companies like Google have allowed this to happen, you just don't hear about it.

That said, your bias against Uber is blinding you.
