> Not really, a lot of phones are 8GB

Not many these days; the last iPhone that shipped with this configuration was the 5c four years ago (I had one; 8 GB sucked).
what a twist!
When I was in college, about six or so years ago, I used Sage for my physics classes. At some point I stopped using it because it didn't really stand up to Mathematica, which we got for free. My professor said, funnily enough, "sage has been taken over by mathematicians!" talking about how it has a lot of support for math uses but not as much for things like solving ODEs that is more of use for physicists and engineers. It's funny now seeing most of the comments here talking about crypto, which I read about in examples for Sage at the time (finite fields) whilst not knowing what it could be used for other than research.

These days I'm a computational scientist, so I end up using numeric tools anyway (numpy is my life). That said, it'd be great to have access to an open source symbolic tool for the times I need them. How has Sage improved for engineer/science types in the last few years?

It's descriptive of the shape of the pasta! Long strands of nuclear material in quark-gluon plasma are called "spaghetti phase", sheets of material are called "lasagna phase", etc.
Because even though it's all a continuum, this animal was much closer to modern birds than to dinosaurs based on the various ways these things are classified. For one, it didn't have a dinosaur style jaw and teeth but a bird beak. Where to draw the line isn't easy, it's fuzzy, but I don't think this case is fuzzy. These were birds by every way we discuss what that means today (which never requires flight).
A bunch of kids at my school had them I eventually got an iPod Nano cause it was an affordable option. After getting used to it I eventually convinced my parents to get me an iPod Classic. Years later I found out just how much cooler the Zune was.
What's compensation driven thinking ? There's a difference between only caring about money vs asking for what you deem fair. Startups always abuse the naivete of new grads and low ball them by saying they are working for a grander cause. That is BS too.
I've not reverse engineered the FB app. I also don't think I'm legally allowed to.

I'm simply "speculating" that a large number of reimplemented classes might not be the reason for the increased binary size from anecdotal experience of building similar app binaries for iOS.

FWIW, I think this comment gives a pretty good reason for why the binary size is large - https://news.ycombinator.com/item?id=17996161
I think you’d have a hard time finding a more controversial language than nodejs.

And I personally think nodejs does a pretty poor job on less resource constrained systems, hence my disbelief that this is a good idea.
I suspect that WindowsPhone 8.1, the nicest phone software ever, was descended from that design effort.

I'd very much like to see a story or an interview with the designer(s), who deserve recognition for that work. If such a piece exists, a link would be appreciated.

Pick any or all of them. Explain what you’re doing and why. Don’t write platitudes about how you’re protecting people’s privacy and have built something privacy preserving if you haven’t used any privacy preserving technologies in your system.
Sure, there's an intellectually sound reason for the lumping: There was a long period of earth's history where enormous reptiles were prominent, and almost all but the crocodile family died out. So, it makes sense to have a word for all the age-of-reptiles reptiles we see in fossils. "Dinosaurs" works great. As such, it includes pterosaurs and sea reptiles even.
You pay Apple for services, so you’re the customer. You don’t actually pay google for its services, so you’re the product.

I saw them as recognizable examples of the type of currently unrecognized thinker he wants to fund. I agree that the fund is not big enough to provide new options to those particular two.

I do think both are examples of how constraints and a long, unusual background lead to outstanding results. A fund like this attempts to shortcut that long climb but I think that would prevent the result from being unusual enough to be remarkable. I think funds like this are better for defined needs that are difficult to fund, such as open research questions.
The Facebook app includes a massive amount of functionality. Open up the hamburger menu and you’ll see a subset of what it does: feed, groups, profiles, video, marketplace, events, camera app, search, crisis response, etc. Each of these has a very deep level of functionality. Facebook are also very data driven, which means they’re probably testing multiple versions of most features at any given time.

Each of the products is implemented by their own team. I wouldn’t be surprised if there are literally thousands of engineers commuting changes to the iOS app on a regular basis. If you are on a small team you can make a lot of headway against bloat on your own. For an app like Facebook it would be incredibly difficult to understand the entire thing, let alone make much of a difference.

Technologies like React Native are supposed to address bloat. It’s much more efficient to ship incremental features in JS (can even be done over the network), but React Native doesn’t solve every use case, and Facebook has a lot of legacy code.
If you know what you're doing the axiom bindings make it the most powerful cas in terms of symbolic manipulation.

Mathematica is optimized for giving you results you need in undergrad classes. Sage is not optimized at all, but can solve problems useful to researchers.

It's the difference between osx and linux.

It would start out under the pressure of all that gravity, and then at the instant of the teleportation the gravity would be gone. With no external force holding it together it would expand outward very rapidly.

Go was designed for a very narrow set of constraints that match what goes on in Google. From my perspective it’s one of the very few general purpose languages (along with erlang) that were designed to specifically match one company’s needs, rather than grown semi-organically.

If your needs align with that somewhat, you might want to use Go. If your needs are different, you should stay the hell away from it.
The point is, you could hopefully train users that a link in an email is an unusual and suspect behavior. And/or start disabling rendering of links in email.

Is there any reason why devs choose elasticsearch to implement basic site search functionality when Postgres full text search functionality would be sufficient?

Real question, because introducing another dependency like elastic over postgresql seems overkill.
Super cool. I had never heard of Duktape before. Seems like there should be some work making Electron compatible with Duktape to reduce the memory overhead of some of our favorite Electron apps cough VScode cough Slack.

(This is probably a naive comment. I have no idea if this would work the way I assume it would).
> I would like to hope by definition a democratic government is one where the tax base can manipulate the government. Going against that seems like suggesting we move to a model of "Taxation without representation".

The tax base and the voters are not the same thing. Unemployed have a vote, corporations do not.

Additionally, in the case of tax system manipulation, it is the richest who wield the greatest power. As a relatively boring private individual, no action I personally take to move my income to regions of low tax has any noticeable impact on a government — 100% of my tax is still less than most rounding errors. Large multinationals, on the other hand… Apple International is tax resident in the Republic of Ireland, and Apple (parent company not International) has an annual revenue of 70% of Ireland’s GDP.

I can see how my language choice led to your comment.

I’m worried this is one dollar one vote, not one person one vote.

Wow, citations too! You're special.

Objects have gravity. A thread about neutron stars, and you came in here to tell us that. Incredible.
It would behave as regular baryonic matter (i.e. plain old atoms and molecules) does at atmospheric pressure. Only it would release a spectacular amount of energy due to how much it was compressed before.

How much energy? We can make a crude estimation: a neutron star has a gravitational binding energy in the order of magnitude of a whopping 10 to the 31 megatons of TNT, and a radius of about 10km. Make a direct proportion to your desired amount of pasta.
Show HN: Hand Sign Recognition on iOS Using CoreML
Which model do you have? I think I'm going to grab one.
Here is a demo of a CoreML model I develop to recognize hand signs, running in realtime on iOS camera output. The architecture is a MobileNet v1 classification architecture. The model is 13 Megabytes in size, and the average processing time is 40ms. Accuracy on Dev and test set is 94%!

Dataset location and inspiration was a tutorial from this link:

https://cs230-stanford.github.io/proj...

The demo here is running on an iPhone 6s. The model was architected using Keras, trained on CS230's SIGNS dataset and custom dataset, and converted to coreml using coremltools.

Code available to train and deploy model here: https://github.com/interactivetech/Ha...

The hypothesis that hunter-gatherers spent more time getting food does not seem to be supported or accepted in academia. Lots of research out the past few years that indicate the HG lifestyle had much more leisure time than agrarian.

This may be confounded by different lifestyles -- without incentives to create and store surplus, no need to work more. No extra benefit.

I am not an expert, but it seems very unsettled whether HG had more or less time spent at work.
It is contractually you aren't supposed to, due to terms & conditions.

Legally, if you are in the USA (or some other country surrounded by water) get on a boat, take it 5-10 miles out, and start (also when on a flight over an ocean would give you some coverage).

The comment you referred to (thank you) makes perfect sense.
I got my PhD in computational plasma physics in a group that heavily used matlab. I'm lucky enough that my advisor was okay with me using numpy and friends instead as long as my plots and figures looked okay. Today, I run a one-man show for my post-doc doing simulations for an experimental group, so I thankfully get to continue this mode of work. And thank god I didn't have to face losing the ability to run my scripts after leaving the university (this happened to a couple of fellow graduates I know!) and today, when I want to run something on the supercomputer, I just run it; I don't have to worry about how many licenses are still on the license server or whatever the fuck. I get how Matlab is a thing and people like it, but potentially having analysis delayed because of lack of licenses seems somewhere between primitive and barbaric in 2018.
This is an awful take and doesn't reflect the truth in any way whatsoever.

The real answer is that Facebook does A LOT. Especially the main app. Facebook also serves A LOT of different audiences in a lot of different regions.

Just consider that there is an entire YouTube worth of functionality inside of the main Facebook app. And that's just one vector of functionality that they offer.
It's not all fun for astrophysicists: the ApJ editors are pretty strict with trying to keep cute names out of the literature. One of my profs at grad school went through quite a bit of effort to get WIMPs as a name, publishing several posters and doing conference talks before submitting to ApJ for the first time.
Counterpoint: Rails is not efficient for new developers who need to get up to speed on it. Other tools are more straightforward to onboard devs; just follow the API docs and read the code. With Rails you need Rails experts.
I implemented full text search in Rails with a PostgreSQL the other day and it was very straightforward. I used the pg_search gem but rolling my own query wouldn't have been too difficult. The best part is I can simply merge my search scope into the usual record-displaying eager loading Rails code and everything just works.
>Mathematica is optimized for giving you results you need in undergrad classes

What makes you think this? Mathematica is used in all sorts research projects, technical fields, finance, and so on. I've seen Mathematica required or recommended in many, many job listings, especially for quants. I've never seen Sage there.

For evidence, here [1] is what you get for searching for Mathematica on Indeed.com. Note pretty much every one of those jobs lists several math related packages. Not one mentions Sage.

Unfortunately you cannot run the same search on Sage, since there is an ERP package that shows up instead. However, from browsing those listing again I find zero hits for the math package Sage.

May I add a follow-up question? Why is their Android app 'only' 70MB?

Are there fundamental differences between Android apks and iOS application bundles that cause these size differences? It seems to be a pattern that iOS apps are just bigger:

- Facebook on Android is 70MB while on iOS it is 491MB
- Twitter on Android is 74MB while on iOS it is 178MB.
- Spotify on Android is 104MB while on iOS it is 164MB.
- Dropbox on Android is 112MB while on iOS it is 228MB.
And in the coming years astronomers hope to image a black hole directly (in radio wavelengths). The few closest supermassive black holes (in center of galaxies) have their event horizon angular diameters just big enough to be resolved by VLBI (very-long-baseline interferometry).

Also, a lot of embedded devices run on batteries. Increasing MCU power doesn’t just increase costs, it means either decreasing battery life or increased battery size, weight, cost, and charge time. This can have quite a ripple effect that might result in inferior products.

Developer productivity: how much better are modern (2018) web frameworks?
I've been using Django since I first learned to code a few years back and only have experience with that and Node.js thus far. I personally really enjoy working with Django.

I was wondering what HN's thoughts were on the magnitude of productivity gain from using these modern frameworks and paradigms, and how that productivity translates to the performance of a business.

Obviously, YMMV based on the company's industry, structure, experience, and other such factors - but, ceteris paribus, what are the opportunity costs of using ASP.NET or PHP (for example), if any?
It's not uncommon, especially if you're working with mobile technologies.
The app does a lot, it’s huge, it even has a built in live game show.
Certificates don't "expire" the way say, milk expires. An expired certificate is just as valid the day after its expiration as it was the day before, and a signature that was made with the certificate is still just as trustworthy. Certificate expiration is just an indication that the organization that issued it wants more money to keep saying that it's valid. I'd have some concern if new firmware was being signed with an old certificate since there's been more time for an old certificate to find its way into the hands of a bad actor, but the company managing the expiration dates isn't in the business of tracking who currently possesses it so I don't really see much reason to pay attention to what they say about the date.
Probably better to link to the people who actually did the original article, instead of some web site that re-writes other people's articles and publishes them as their own. It's the laziest form of journalism, if you can even call it "journalism."

You can say that, but I know lot of scientists and mathematicians who extensively use Mathematica in their research.

Yes, digital often have the option of switching, but that filters the number of vehicles.

My car has several digital measurements (fuel efficiency, range until empty, odometer) with no option to change units.

> All analog dials I’ve ever seen are dual mph/kph

Yes, but one is usually much more prominent. Again using my car as an example, the km/h markings are white on black, with clear marking every 10/20 km on the gauge. The mph font is about half the size, dark red on black, and doesn't match up with the gauge markings.
> The resulting behavior appears effectively undefined to the programmer, because the point of invariants is to ignore what would happen when they are broken.

I still think there are big differences here, especially when we think about these things as security issues.

If you write a program that's supposed to draw some pixels to the screen, and you have a logic bug, you program is going to draw the Wrong Pixels (https://xkcd.com/722). But your program isn't going to install a rootkit on your machine, or mine bitcoins, or send all your spreadsheets to the bad guys. If you never call the `mine_bitcoins()` function anywhere in your program, there's no way a logic bug can make you somehow call that function.

Not so with undefined behavior. An attacker who exploits a buffer overrun in your program can make you do anything. This almost sounds paranoid, but as soon as your code is taking input from the internet, this is really truly the problem you have. This sort of problem is why projects like Chrome spend millions of dollars building security sandboxes for their C++ code, and researchers still keep coming up with ways to break it.
It is pretty interesting that he chose two people who don't need philanthropic funding.

Hi - I am the guy who started Sage. If you have any questions I can try to answer them here.
Are you describing something you wish that node had, or something that actually exists? As far as I'm aware, native modules are the FFI for node, and that every package that involves presenting an FFI to the developer is using a native module to do it.
Seconded.

Likewise, Stephen Baxter's "Flux". (Even crazier, here the lifeforms dwell inside the neutron star, in the neutron superfluid.)
The article only mentions land value once, and in my opinion this is a huge oversight. There's articles going back to 2010[0] that speculate that a land bubble had been going for a few years, and when that's coupled with quantitative easing it means that people had to borrow increasing amounts of money to buy an equivalent amount of land. Combine that with decreasing crop prices and additional debt load that was taken on as a result of buying/fixing equipment, and you have a perfect storm.

I agree with all that, though I also want to add that the converse is not true -- clear thinking is not, by itself, enough for clear exposition. The latter requires investing additional effort, which many people are unwilling or unable to make.
Agriculture subsidies. Farming in the US hasn't been a fundamentally profitable business for decades but the government provides a massive welfare program to ensure the survival of farmers, maintain a stable food supply, and keeping prices low for consumers.

I made this comment below, but about 6 or so years ago, I found it could be used for science and engineering purposes like solving ODEs but it seemed a little bit rough at that. Today, is it improved for use for science types? Do Sage and Cocalc find users in this area?
This process of farm consolidation is inevitable. Agriculture benefits from economies of scale, even 2000 years ago the Roman latifundia fed an empire efficiently.
