Multimodal transportation is something I've been thinking about as well. The original idea was to focus on neighborhood exploration via walking. But I'm wondering if allowing folks to put in biking or car (e.g. for an Uber from point A to point B) might open more use-cases.

I agree that stuff like arbitrary layers and things like that is really cool, but this was hard to implement as-is :) I want to wait and see how people might react to this set of features before I add more.

As for monetization, I think it's too early for that - right now, I want to see if this is something that people really want and would use. There's always the option of promoting local businesses in various ways, or paid plans for additional features that might get built along the way. But the prerequisite for all that is that this fills some need.
I’m personally on the side of opt-in/choice, maybe due to the traditional nature of controlling your credit card.

Although, I’d love to see a show of hands from anyone IT related that hasn’t witnessed an outage caused by an expired card/billing account issue. Oh the SSL certs, exchange servers, SaaS apps, domains, etc I’ve seen go up in flames temporarily because of billing issues over the years.
Where to Start with Code
Hello HN -

I am an artist, born in 1984, which means i'll be 35 years old this year. I taught myself html css and was able to make some rudimentary websites and modifications to my tumblr as a sort of gateway into css, html and code. Recently i made some twitterbots that i was able to copy and paste and cobble together stuff and deploy to heroku! using python and some other stuff (im sure not at all in best practice) and run those for a bit. I often find myself wanting to write programs (for example a scraper for a website) and know enough of the language to find the code on github or look through questions on stackoverflow, but i feel like i am quickly out of depth; as i want to customize or go a bit futher; or sometimes i feel like i need some basic knowledge that i don't have. i was wondering if anyone here has advice as to learning code or as an artist (entrepreneur) how to go about working with developers and coders on very small projects. thanks so much
That isn't what happened at all (see the rebuttal by revvx). Joe was a great guy and also a great systems thinker. And he was the last person to worry about "bandwagons" (quite the opposite!)
>> There are still companies I know of that do symbolic AI (such as https://www.cyc.com), but I very rarely hear of new research in the field.

I can't answer your main question but, as a practical matter, if you don't hear of new research in the field it probably means you're not tuned in to the right channels, which is to say, the proceedings of the main AI conferences that cover a broad range of subjects: AAAI, IJCAI, IROS, ICRA, plus the more specialised ones, like AAMAS, ICAPS, UAI, KR, JELIA, etc. Any interestting research in symbolic AI is going to be there.

If you get your news from the tech press and the internet, you won't hear of any of that stuff and won't even know it's going on, because, let's face it- the large tech companies are championing a very specific kind of AI (statistical machine learning with deep neural nets) and, well, they have the airwaves, they have the hype engines and their noise is drowning out all other information on the same channels.

For the record, work on symbolic AI is still going on. For instance, the subject area of my PhD research is in Inductive Logic Programming, a branch of symbolic, logic-based machine learning. This is not just active, but going strong with a recent explosion on research in learning Answer Set Programs and the work of my group, on a new ILP technique, Meta-Interpreterive Learning. If we're inventing new stuff, we're still alive and well.
Yes, that is right the population growth rate started declining more than half a century ago. In 1962 the growth rate peaked at 2.2% and has halved since then: https://ourworldindata.org/world-population-growth#the-globa...

The projections from different research teams differ in when they expect the population population to peak. IIASA suggests what you say, the UN expects it later. I looked at the different projections (and what is behind the differences) here https://ourworldindata.org/peak-child
Using calories to define your diet? That doesn't sound like a good idea. I would much rather focus on what I eat than bother keeping up with imaginary numbers.

Nutrients and micronutrients are a real thing you can track and experiment with. There's nothing like finding a new food that gives your entire body a "high".

And no, Burger King won't do that, ever.
Yes, it is a Desktop app. Would you like to see a download button for a Linux installer while browsing from iOS? What would you suggest to show alternatively?
Maybe that's still ahead of us and there never will be sufficient data available for a meaningful answer.

Or, we're indeed in a simulation which is aimed to preserve the image of species that evolved beyond physical form eons ago.
Both graphic design and building architecture require significant knowledge of UI/UX (yes - even building architecture).

Since UI/UX is making its round in the technology environment, I wouldn't be surprised if trends 'hop' disciplines despite being loosely related. This may be why more arch symposiums are appearing.
Every scientific paper already contains a summary. It’s called the abstract.
Summarizing scientific articles and writing them are not the same thing. I think this is very interesting work (although I have not read the paper and my knowledge of AI and NLP is very superficial), but the headline really puts me back.
This was Netscapes design. I would guess it was designed like that because it was the simplest way to handle error conditions. Initially JavaScript was very simple and didn't even have exception, so there was no way to report errors.

> $8 for an overpriced and overspiced pasta dish.

Hardly overspiced. Take a look at the amount of salt and MSG in such dishes. Salt and MSG are much cheaper than spices.
>I really don't get why the community is hell bent on reinventing the wheel, especially when the main defense of npm is that you don't have to reinvent the wheel.
It's really disheartening to see that the best minds of the generation are busy spending time to reinvent the same old things instead of trying to improve upon the existing systems.

I think it might have to do with people considering 40 as very old in Silicon Valley and those in their late 20s and early 30s have barely learned this lesson.
Again, please do your homework.
Its worth it when its gonna prevent deaths because of propaganda. In India, its a main source of misinformation and it has caused numerous deaths. For example in last month's deadly Pulwama attack which killed 40+ soldiers in an attack by a terrorist in Kashmir, Right wing Hindu extremist groups started spreading misinformation saying that "Kashmiris all over the country are celebrating the death of soldiers." They shared old photos of random kashmiris being happy. This let to multiple attacks on the kashmiris all over the country. This is exactly what needs to be prevented from ever happening again. I'm willing to give away social media for a few days if its gonna save some fellow countrymen's lives no matter if they're innocent or not. Please understand the context.
Producing value has no externalities? That's new!

> As for landfills being cheap, that isn't a bad thing. That means the externalities at those sites are low.

No, that means that most of the actual price is not accounted for and is dumped on the public instead.
LA to Area 51 is 25m flight and their boarding procedures are probably quite a bit more efficient compared to normal passenger flights. doesn't look too bad compared to other people's commute in LA, i imagine.
> Now that Ford builds a model for Europe, I see them a ton here in Hungary.

Which doesn't change the fact that it's an aspirational "style over substance" decision for the majority of buyers, especially those buying the 2.3 EcoBoost version. Recently I also do spot them quite frequently in Bulgaria, but their resale value on the second-hand market is tragic, they lose something like 70% of their value in 3 years even with low mileage.
Simply write code and learn the hard way. I can tell you from experience that copy and pasting does not bode well with the learning process.

You have to make a significant effort in order to learn how code works in different scenarios.

Anyone can take Google Translate and talk to a Chinese person in a broken, poorly translated language. But to learn Chinese (programming) as an actual language requires commitment and determination.

Once you get over this hurdle, the rest should be much easier to manage and understand.
You don't have to put airplane mode on. You could just disable all data instead (LTE, WLAN, BT). This will disable all radios except phone calls. That way, incoming calls still work.
> We could just build upwards

You can't just build up and up and ignore the issues at ground-level. As you add more vertical housing you still need more space and resources at ground level, for public transport, for parks, for schools which need sports ground, for everything. Everything else continues to get more congested and building vertically solves none of these inherent problems.
You mention it in your last sentence, but most of these tales forget to mention it at all: java was slow. I mean, slooooooooooooooow. And that reputation stuck for much longer than it was actually true. Java applets were an abomination and you wanted to repeatedly stab yourself in the head while using even a simple one. On a then-average p166 with 24mb of ram, your browser would go unresponsive while loading, jumpy mouse cursor, os starting to swap, and then some irregular annoying hangs while the GC did its thing. Not to mention how ugly awt and swing looked even back then.

Modern web is a joke regarding resource usage and complexity etc., but java was a shitshow in practice, except on beefy servers.
> Plenty of companies create, use and release open source software using permissive open source licenses.

Typically, these big-corporation permissively licensed projects are loss leaders and some other part of the company is making the profit; think Android (funded by Google's ad revenue) or LLVM (funded by Apple's iOS hardware sales, and again Google's ad revenue).

If you look at companies that have successful business models where the income actually comes from the open source software itself (Red Hat/SuSE), you'll find a lot of critical copyleft GPL projects (GCC, Linux, glibc, systemd, Samba, ...).
Looks like half a vagina to me.
> So if they had been diligently saving until 2009, then cleared out their financial buffer in 2010, they would quite reasonably be caught flat-footed in 2011?

If - sure. And if they hadn't lobbied the CDU/FDP for years to take it back it probably wouldn't have happened. Many ifs. But they didn't save up and they did lobby both parties.
The thing mentioned in the article sounds like it has more to do with the high ceiling height of one floor, not a whole building.

As far as I know most height restrictions are to do with casting shadows over other people's property.

For example, I own an apartment in a complex where some buildings exceed the area's height restrictions through an agreement with the government because the tall building is placed in the middle of the southern side of the block and hence only shades buildings in the same complex. If you're just building one building, that would be a problem.

Of course there are earthquake considerations, but everywhere I have seen them they're to do with choice of construction materials for a given size.

I wonder about the potential of fusing subsymbolic with symbolic systems, continually learning and updating a set of feature vectors to serve as a dictionary, translating between the subsymbolic and symbolic parts of an integrated learning framework. I think of that as analoguous to how the older, more intuitive parts of the brain and the language-based, reflective, linear, reasoning parts work together.

Your objection has merit, but this discussion seems to be focused on "what should we do going forward". While we currently suck at good & economical long distance transmission, this hardly seems to be based on physical limitations. Thus, if it is a worthy goal, we can & should guide our economies towards mastering that tech and driving prices down, kind of like we did with e.g. solar panels.

I'm especially eager to hear more about developments in / experiences with UHV DC lines, like in this ieee.org article + discussion: https://news.ycombinator.com/item?id=19295838
This very program by visa allowed LA Fitness to steal several hundred dollars from me after I thought I had unsubscribed (they are also known for being unscrupulous about customer subscriptions). I thought I had cancelled my account, and was unworried about them continuing to charge me because I had recently gotten a new card number anyway. Well, unfortunately WF/Visa had given them my updated card info without my knowledge at a time when I didn't check my statements for several months (I audit charges MUCH more regularly now). They had kept my account active because I hadn't realized how convoluted their "unsub" process was and hadn't jumped through all of their over-the-phone hoops. Long story short I was out several hundred dollars over the course of almost a year, and the CC people were unwilling to help because the charges went undisputed for many months. A very angry visit back to the LA Fitness location was the only thing that remedied the continuing subscription, but I never got my money back. Caveat Emptor.

This is a classic great listen with an interesting perspective. Having had listened multiple times to fill an otherwise silent void, his arguments feel geared towards those who have 100% without a doubt committed a crime, which is fine, but such advice during a routine pull over may be counterproductive.

Of course, using his example of not admitting you were going 'x' over the speed limit is obvious (not to most, though), it may be beneficial to have -some- transparency and personable traits that most often eases the situation.

At this point, you may be asking yourself how this could possibly ease a scenario as such... Well, here's the thing - if someone were pulled over (no matter what cause)and acted as many 'Sovereign Citizens' do, it can be expected without a doubt that escalation will occur due to insubordination. It's a very fine line, and honestly may be a gamble depending on the encounter premise, who the official is, and where you are located.

In short: Think before you speak :)
Pay close attention to your diet and sleep. Try avoiding sugar and high carb foods. Try journaling your sleep quantity and quality, your moods and food you eat. Try finding pattens in the journal and keep experimenting till you find a combination that works for you.

I generally agree that the lack of taller buildings is mostly regulatory, at least in areas not prone to earthquakes. Look at the bizarre weirdness of air right laws, and especially the buying and selling of air rights, which has caused a rise in odd needle-thing super-tall luxury apartment buildings in cities like NYC.

So while I agree that we need to build upwards and increase density, we have to be mindful of air and light, especially air quality and sunlight at street level.
I agree.

Some “safeguards,” eminently type systems (with algebraic types and inference if possible) I've slowly come to value a lot, especially when maintaining a codebase for an extended period of time.

But otherwise, I still prefer to reason over my code, with the aid of at most a few debug prints / logs. Breakpoints I only use very rarely. Other debugger features not at all.

But I remember it taking many years before I could build a complete working picture of the code I was writing (or reading) in my head. Before that, I was basically horsing around. Thankfully, that was around high school time. By the time I got into the industry, I already had that skill finely developed.

Nowadays, I don't think many fresh graduates have it, and yet the industry prefers hiring them, rather than more experienced (older) people. Go figure.

Thomas Malthus attempted to describe the future of the world population in 1798 in his book, An Essay on the Principle of Population. He predicted a doubling of the global population every 25 years until a lack of food limited the population through hardship or famine and death. Pierre François Verhulst went on to mathematically model this bounded exponential growth and, in doing so, created the logistic function. The necessary data to create a chart like the one in the article didn't exist then, but Malthus' book did contribute to the passage of the Census Act of 1800, which enabled the first census of England, Scotland and Wales.

Let’s be clear. I’m not saying that she has to give a statement, but if your a third party writing a blogpost about a case where the victim has come forwards, you could state that. You could even ask the victim what she thinks, and just state so if the victim doesn’t want to comment.

What I’m saying is that it’s confusing that everyone involved is being vague even about public facts. Even you are confused as you’re linking the statement from someone who isn’t the victim presenting it as though it was from the victim.

What I’m saying is really just that everything seems very confusing. It feels like the whole affair would benefit from someone involved just coming forward and honestly reporting what they feel or what they know or didn’t know happened or what they want to happen.

As it is I’m none the wiser, but since I both use, love and often recommend DataCamp, I am extremely keen on hearing if the leadership engaged in something that I cannot support in which case I will definately look for alternatives. I’m currently hearing a lot og posts saying “trust me something happened either in the incident or the response to it that should make you not want to support them.... can’t tell you what but trust me”. And I really just want to know some of the facts of the matter instead of just vague hints that “stuff definately happened”.
