> I started the Udacity self-driving car Nano-degree. (I won't be finishing it, but that is another story.)

I'd be curious to know why myself?

I'm about 2/3rds of the way thru the second term (I'm in the November cohort), and I plan to finish the nanodegree.

What I have found, though, with this second term, is that it seems to be a rehash of the CS373 course (I took that back in 2012, when Udacity first started) - though it also has taught a few new concepts for me (I like the fact that it is mostly done in C++ - which had gotten really rusty for me - but now I am liking C++ more).

I'd also recommend the Coursera ML course - from what I know, it is basically identical (if not the same material) as the original ML Class from 2011 (I took that one, which was my intro to MOOCs). If you can wrap your mind around the programming language used (Octave - basically an open-source clone of MatLab - where the main primitive is a vector/list), you'll find it does a great job at explaining many concepts that you might have had trouble with in the past (when we got to neural networks and backprop, it finally clicked for me - same with how think in terms to figure out how to parallelize processes).
Exactly. Also they become fat over time shifting the reality of costs.

XML is fundamentally much more complex than JSON so any XML parsing library will inevitably present more complicated API. I kinda like XML (!), but there is no point pretending that using it is as simple as JSON.

Stories like there are why I won't consider Google as an infrastructure provider for our SaaS, regardless of the technicals around their services. Thank you to the original author/s for writing the post, it reinforces the warning to avoid providers like this.

In HomeAutomation's case, the amounts are relatively small (though still potentially massive to them). If their monthly infra spend for firebase started out at $10k a month and went to $1m, would only way to have issues resolved still be to hit the front page of HN?

Risk factors into our technical decisions, and trust factors into risk. Particularly when billing is concerned, needing to wait a month is ridiculous. Assuming the post is accurate, ignoring billing-related emails is inexcusable. Any organisation this incompetent is one that you should not trust with your critical infrastructure.
My Nexus 6P died last night after <2 years of service, and my wife's first 5X died after only 4 months. Now that the Pixel is priced as a premium device in line with the iPhone and other flagships, I find myself considering a non-Google phone for the first time since the N1 was released.

Given the short support curve for most Android devices from Google and especially from third parties, that device is quite likely to be an iPhone. What was unthinkable to me just a few short years ago is now reality... I type this on a MBP and I might be convert my phone platform now as well. A true testament to the constant change in the marketplace, and the need to evaluate based on features and performance rather than fanboism.
Not round trip efficiency. The reasonable metric is electrolysis-only efficiency. Longevity is another good one.
Shortly after RSS 0.9 came out RSS 1.0 reformulated the RSS vocabulary in RDF terms. Of course the modern (sane) successor to RDF/XML is JSON-LD.

So I'm hoping for JSON-LD Feed 1.1 and a new war of format battles. Maybe we can even get Mark Pilgrim out of hiding!
"Primary energy source" is a term with a specific meaning. I'm not talking about market share.

Primary energy sources do not require any type of conversion. Fossil fuels, nuclear, wind, and solar are all primary energy sources. Free hydrogen isn't found in nature. It can be made by splitting water using energy from a primary source. The catalyst described in this press release makes that process more efficient, but it still takes energy from a primary source to create hydrogen.

You're right, backtest overfitting is a problem. At Quantopian, we spend a lot of time on education helping people avoid overfitting like this (https://www.quantopian.com/lectures#The-Dangers-of-Overfitti...). It is easy to make a backtest look good by tweaking things here or there and that's just textbook overfitting. If you follow good statistical principles for model development based on a sound economic basis, the backtest is more of a sanity check to make sure that whatever signal you have found survives the introduction of market impact. If you have consistency between the statistical aspects of in-sample performance (your backtest) and true out-of-sample performance (paper trading on entirely new data), there as an increased probability that you have found a viable signal.

Disclaimer, I work at Quantopian.
That's great! But it does make sense why google and FB would be taking different paths here.

As much as I was disappointed with FB's decision on Parse, I can also understand the reasoning behind it and I actually think it was the right decisions for the company.
In contrast, Google is playing in the cloud service vertical and investing in the future of Firebase is totally aligned with that objective.
Some (possibly wrong) chemistry:

Hydrogen has a specific energy of 142 MJ/kg [0].

1 water molecule has 2 Hydrogen molecules and 1 Oxygen molcule. Hydrogen has a molecular weight of 1, while Oxygen has a weight of 16 [1][2]. This means that, by weight, water is about 1/9th hydrogen. So 9kg of water should give us 142 MJ worth of Hyrdogen.

Gasoline is about 46 MJ/kg [0], so 3kg of water should give us the equivelent of 1kg gasoline.

Gas has a density of .77 kg/L [3], water has a density of 1kg/L [4]. So 3L of water, should be about 2.31L worth of Gas.

Also, if we keep the water that results from burning hydrogen we may be able to avoid needing to re-purify it.

I don't know about you, but I always found Rust a real pain to use. One could say Rust is "secure", but you can still break Rust too. Incompetency knows no bounds. It's better just to learn to be competent than complain it's not dumbed-down enough for one's way of thinking. Hence, I should still learn Rust, and you can still learn C.
I've been wondering the same thing. It is why I don't like the fact that we need increasingly specialized types of computers to do ML. This is also why I am very interested in research that is not based on deep neural networks, which seem to be especially hungry in terms of training data and hardware power.
It's true that the comment was a bit fluffy, but it's also the sort of whimsical tangent that is in the spirit of this site, which is intellectual curiosity.

Intellectual curiosity often takes up seemingly trivial details and plays with them for no particular reason. Mostly nothing important comes of it, but sometimes something really does. In any case it would be a big mistake to try to push that kind of thing out of here—it's well within the scope of what HN exists for.

Thanks. This is helpful. I guess part of what I'm wondering is how much Kotlin interfaces compare to Scala traits in the sense explained here:

https://en.wikibooks.org/wiki/Scala/Traits

Or, in another example, how does use of Rust impl map onto Kotlin?

http://www.jonathanturner.org/2016/02/down-the-rabbit-hole-w...

I really don't mean this as a criticism of Kotlin, I'm just trying to map this all out. Kotlin seems nice and like something I could use, but I'm sure it has its boundaries also.

That's with Kotlin's much smaller runtime. It's the stdlib that matters, not the language. Which is why the JVM or an emulated version of it will be around on Android for a long time.

And the way Apple handles this for sandboxed applications is by hosting the open panel and save panels in a separate, privileged process, and extending the app sandbox around the selections made by the user as necessary. It's pretty neat.
Interesting, if true.

And if true, it'd also be interesting to know to what extent: the current overheated markets in SV/NYC are skewing the numbers; and (2) foreign investment (read: money laundering) may be weighing in on the numbers, as well.

There's this new game in hot real estate markets where houses are listed intentionally well below market to attract traffic and encourage multiple offers. Here in the Bay Area it's standard operating procedure, and houses are expected to sell 20-30% over asking. The 'list price' is really just an opening bid, and anyone looking for houses in these markets is adding at least 20% in their head to ballpark it's actual likely sale price. This is a big change from the past, and from many existing markets that try to list prices at the top end of where they'd appraise, and were expected to be negotiated down by a single buyer, not up by multiple buyers.
That analogy doesn't work for me either. History is littered with amazingly beloved musicians that played entirely by ear, with little to no literacy in the larger world of music, that basically reinvented everything they knew of music from first principles with never studying the previous culture or proper music literacy or music theory.

I think the dictionary definition is accurate/adequate enough and you may have an implicit "good" or maybe "professional" somewhere in your usage of musician, that I don't. One is a value judgment (history is also littered with "terrible" musicians that were still musicians, or contributed to the craft) and the other an economic judgment, neither of which I see as necessary to describing who is or is not a musician.

I am (was) a chemist but I find this research area somewhat puzzling. Electrolytic hydrogen production has been industrialized for more than a century. Put nickel electrodes in an aqueous solution of potassium hydroxide. Separate anode and cathode with a porous diaphragm. Run direct current through it. Get pure hydrogen. "Simple" alkaline electrolysis is only ~50% efficient, but that means there's only a factor of two efficiency gain possible no matter how good your catalyst. Large commercial electrolyzers from a decade ago reached ~70%. Why so much research on further marginal efficiency gains from new catalysts? Are there other costs that fall faster-than-linearly with improved efficiency?

Indeed and I find it an absurd false dichotomy to suppose that it's either/or. Why can't both government and private enterprise both be discovering the future at the same time? Granted, some enterprises/initiatives will fail, but that's kind of par for the course since nobody can predict the future.

In all fairness, they're taking a more or less solved problem (feeds), so they don't really have to figure things out there, and they're porting this established solution to a very well-established technology (JSON), so also don't really have to figure stuff out in that sense either.

As far as scenarios where it's feasible to get the answer right the first time go, this is a reasonably realistic one.

EDIT: Also, if you scroll to the bottom of the page you can see they have let a whole bunch of people look at the spec before releasing it, so there has been at least some peer review.

If you can afford it, do the nanodegree.

I did the CS373 course back in 2012 - and I have found that the nanodegree (which I am taking, and I am about 2/3s of the way thru the second term) touches on more than a bit of new stuff that I didn't find covered in the CS373 course (at least back in 2012).

First term alone is worth the price, I think. Learning how to use OpenCV, TensorFlow and Keras, then using that knowledge to "drive" a virtual car (I built a version of the NVidia End-to-End CNN and trained it using CUDA and my GPU at home, using data I derived in the simulator by steering the virtual car using a steering wheel controller I bought just for that purpose).

Second term so far has felt mostly like a re-hash of what was learned in the CS373 - although, learning about extended and unscented Kalman filters for integrating LIDAR and RADAR data was not something covered in CS373 (only the basic Kalman filter - useful in itself, though).

My goal is to finish this puppy.

From what I have heard (anecdotally), when the initial class started, for the first term there were approximately 30,000 students enrolled. When term 2 started, only about 300 of those students enrolled for the new term.

So far, I'm doing pretty well with this. Considering I don't have an advanced degree, that I am a self-taught software developer, and I am going to have my 44th birthday in about a month - well, you know the story about dogs and tricks; that don't apply to me.
I'm just seeing this now (I just got an email from someone that mentioned it), but thanks to everyone for the kind words about my services and I'd be happy to take a look at your resume (or anyone else that might like a 2nd set of eyes) and offer suggestions for services.

> No it doesn't allow you to make an informed decision. It only indicates the presence of offensive words from a list you do not know, but trust anyway.

This seems overly skeptical to me. Not having the list memorized doesn't translate to me not gaining any information from reading the label. I imagine there are additional terms I'd probably want to see on the advisory list, and possibly terms I don't think merit parental advisory. Still, the label does inform me that reasonably responsible people believe other reasonably responsible people may find the content inappropriate for young children. Surely that counts as at least some information!

> To keep an eye on my son, we just mirrored the TV and stereo signals from the living room to the kitchen. We actually see and hear everything he does. THAT'S how you stay informed!

I think you inferred that I was saying a parental advisory label was the only way to stay informed, and that's certainly not my view. For example, in my house, nobody turns on the TV (not even me) except for on Saturday mornings to watch cartoons. I have 5 kids; I can't possibly monitor everything they watch all the time -- so we turn it off, they play during the week, and we watch 1-2 hours of TV a week as a family.
In its current form, net neutrality has been on the political menu since 2004 in the US. It's possible to argue that it's been around in some form or another since the 1920s, and certainly since the late 1980s.

Netflix didn't begin their streaming service until 2006 or 2007, if my memory is correct. They might lobby for it now (of course they do, it's in their best interest), but they have nothing to do with the original idea or policy.

I happen to think that net neutrality makes for pretty good policy, but I'm open to arguments that suggest otherwise. "Netflix supports it, and therefore it's bad" is not one of those arguments.

This is what the whole article is about:

[intro]

The life of a tomato is halted tragically early. They’re wrenched from the vine in their adolescence and fledged from their natal farms when they’re still green and hard as stones. Snipped from their vines, the fruit is never allowed to ripen in the field and develop the sugars and flavor chemicals that make them taste like something other than a verdant rock. Unfortunately, for large-scale commercial farming this is the only way. Imagine shipping squishy, perfectly ripe tomatoes across the county. They’d arrive sauced.

[...]

If farmers could somehow allow a tomato fruit to ripen on the vine and develop flavor without going soft, everyone would be happy. Farmers get high yield, consumers get a tasty product, and tomatoes everywhere could keep a shred of their integrity.

This is something I've particularly noticed on HN.

Someone will post a software project, and some of the comments are very critical. (Not personally insulting, just very strict about correctness).

Then someone else will post a hardware project, and I'll look at the soldering and wonder how the hell it works with such awful solder joints; or I'll see the hundred and twenty connections using the same colour wire with no idents and I'll think how glad I am that I don't need to buzz those out to fault find. I don't mention these, and almost always no-one else will mention them either. They understand that these are often learning projects from someone sort of new to tinkering with hardware. There's an open appreciation, and I wish that was extended to more of the software learning projects.
The question is if they can extract value out of the customers' data that's on or passes through the servers and services that they manage, or if it's too messy to be of use. And my answer to that is that this is Google's primary business model, so surely they could if they wanted to try. Whether they do (surely not) or should (definitely not) are different questions.

The effects of antibiotics entering the water table pale in comparison to 1. the extra pesticides that enter the water table from growing the extra plant matter that must be used to feed free-range animals, and 2. the pollution from the processes required to create the fertilizer to grow said plant matter.

You can think of an animal as a way to convert a whole lot of plant matter into a little meat. Growing plant matter for feed, itself, pollutes in various ways. A given animal might be less healthy eating corn than eating grass, but if it needs to eat 10x the weight in grass in its lifetime... that animal, raised that way, is now likely responsible for 10x the pollution.
Anyone know of good online tutorials for Kotlin? I learned Swift for iOS development and customers have been asking for an Android version of my app. Sounds like Kotlin would be a good second language to learn.
