I don't get how a city like Melbourne can score as highly as it does considering the state of LGBT laws in that country. Surely this has to be taken into consideration.

I'm not sure what you're point is, because I captured that.

Each journey has a 35/135 million chance of you dying in a terrorist attack. I multiplied that by the number of journeys you would take per year.
At least it's more visually engaging than the Tages-Anzeiger's visualization discussed here: https://news.ycombinator.com/item?id=12310032

However, I do wish they could've shown actual acceleration and speeds as opposed to the easily calculated average speed. Wake me up when someone makes the effort to find all the historic footage and overlays it on top of one another.
Doesn't really matter, though. If you have to build your tools up from that level, it's going to cost so much that only governments and huge corporations can do it--and those are exactly the people installing the backdoors in the first place, so we're back to square one.
This was an unfortunate result, SharedCount and @yahel are awesome but understandably tired of fighting this. We're starting up engagedcount.com to pick up where they left off. We also have some ideas working for twitter counts in the pipeline.

Maybe it's a hopeless struggle but I think that with machine learning becoming as powerful as it is, this data is better off out in the world than behind these closed gardens.
I wish they had done this few years back. I've wasted waaay too much time trying to minimize and cram down Qt to the small devices.

Games are a super competitive field. I wouldn't expect commercial success unless you can clearly identify an undeserved market niche that you can fill.

Though of course market demand is also key in creating a successful ebook or SaaS product. Of the ideas that you have for ebooks, SaaS products, and games, which has the biggest unmet market demand?
Is it just me or has there been a proliferation of "strategic startups" lately? They never intend to turn a profit but rather seek to become a pawn in the larger game between e.g. Google and Apple. Of course, in a winner-take-all market, it should be the easiest way to "win". Go Big or Go Home is now Go Big or Get Acquired...

That's what deep dream was about to some extent.

Yes but unfortunately after the UTC research was canceled all development on the nuclear lightbulb design was stopped while other methods of nuclear propulsion received at least some mindshare from theoreticians and engineers. The nuclear lightbulb now rots in the NASA technical archives. Most of the engineers who worked on it are dead and we haven't made much progress on the material science needed to pull it off (I.e. we still don't have a solution to neutron damage and runaway heating in the single crystal berrillium oxide sheath as well as a viable design for the fuel injector).
Or compromise; write up an awesome blog post about how you wrote software to turn their photos into proper scans, and reject their homework (with a link to the blog post).
Do you know https://www.indiehackers.com/ ? They have interviews with coders on their stories. Maybe it's a good inspiration for you.
This isn't "passive income", this is a side-gig. Yes, it may in time generate recurring revenue that you could consider passive, but probably it wont be ("I only have to answer a few mails a day and develop stuff every weekend!")

"GPUs and OpenGL must be more energy efficient at this task than software rendering, and I would imagine that important embedded devices with graphics displays must all have GPUs or will in the future?"

Adding to what was said in other comments, another problem is graphic drivers that mostly come as binary blobs and no source code available. Many projects, especially missions critical ones, avoid having uninspected binary blobs in their systems.
Entirely disagree with you here:

-Nowhere was it insisted that all servers are equal.

-Most people would prefer a hosted solution to hosting one locally(not constantly using their local machines resources)

-For many apps the performance and uptime of a server is of enough importance that this simply wouldn't work.

-A hosted solution provides a stable controlled and relatively unchanging environment, depending on what else you use that box for.

-Unless there's guaranteed uptime(which there isn't in this case) you have even more merging headaches. (read 4 slave-peers(not really even 'peers' in this context) all have different diffs after a week of the master being offline)

-Putting an app on a box somewhere isn't a 'massive scale solution'.

>If you want to have a reliable server instead of just a server, then you want more than one server.

No. Not for a personal or small app you don't. You can have 'reliable hosting' (say one of the many VM providers backed by solid hardware and a RAID tolerant to multiple drive failures). Reliable doesn't mean completely immune to failure, and you're underestimating the reliability if you think this is a regular occurrence. Your average hosting provider offers orders of magnitude more reliability than any users local PC or mobile(even if we're talking a constantly online desktop with wired ethernet).

It's just a ridiculously complicated thing your asking for here while simultaneously dismissing the parent comment as 'hiding the problem behind an abstraction'.

Case Study: Chatbot as a Business
None of them are really passive. E.G. an ebook is a lot of work and you need much time to write a good book, especially on a niche.

And when you have it, how long could it be sold, until the technical thing is outdated?

A SaaS must be updated from time to time, bugs must be fixed ....

A mobile web based game is much work too.

A 100% passive income is really hard to find. Do something you like and try to sell parts of it (ebook, blog, saas, game, whatever).
Through-hole components won't save you.

I've done some. https://wrapbootstrap.com/user/acesubido. In it's lifetime across 3 years I got around 5000USD~. Back then when bootstrap was still new it was lucrative to write website templates, since it was easy and there were few templates going around (circa 2012-2013). The process was:

- Look for a famous template

- Rewrite it in bootstrap

- Get it approved

As of 2016, the front-end ecosystem has grown big. Material Design and other UI/UX innovations (fancy modals, fancy sidebars, scrolling animations, etc.). This causes the market/buyers to look for themes that will allow them to look like the next AirBNB or Google. Theme marketplaces are looking for bootstrap/foundation templates jacked full with these javascript libraries and fancy stuff, increasing the barrier to entry for stuff to get approved.

Here was my experience writing a template last year:

I spent 2 months of weekends and weeknights to scout out the competition and worked on an admin theme. Made it with fancy charts, animations and a few javascript libraries embedded in that the market would probably want. I proceed to try and get it approved. Then, I found out I'll have to fight through other big agencies that crank out these themes like pancakes for a living while they price it 20-30% lower than mine. These agencies also sell these themes in other marketplaces that make them very popular choices over others since they can support customizations and what not.
I've thought about this as well but haven't come to a conclusion.

Some ideas I've had are:

* Website templates (i.e WordPress). Downside: Will require constant maintenance to stay up to date with latest versions, bug free, and, secure

* Apps. Downside: Very competitive field

* Very NICHE apps.

This last point, is what I think would be really useful. For example, there's a sync for Fitbit / Apple Health. The guy who made it, has made two different apps, one for each direction, and they both cost $7 each. If you want to sync FROM Fitbit to Apple Health, that's $7. The other direction? Another $7. This app does it well and because it's such a niche thing - only for Fitbit and Android users who want their data into Apple Health or from Apple Health, it seems to work.

The problem here is finding these niche areas where there's a void to fill - these apps are so simple because it's basically just 2 UI controls (to/from date, and a button) and then two API calls.

I'm now trying to think of these things whenever I end up in a situation where I felt "damn, other people must want this too, why is there no simple app that does this?"

Ask HN: Choosing an open-source license that's compatible with selling?
I am in the process of choosing a license for a projet I'm doing. I want that code to be used in other open source projects freely. However, if people need to use it for a commercial product, they should acquire the rights from me.

What license would fit this? What choices are there? Any existing examples?

Thanks.

Ask HN: How do you make logging consistent
This is a software design question: I have different components which do similar operations (similar, not identical) and I want to normalize the logs that each component emits so I can make diagnosing issues easier. What approach should I take?

One thing I have thought about is using an error code for a specific known fault and then emit a message based on the error code (think M$ error codes) - same message parameters for all components but the values differ.

I'm more interested in hearing how this has been addressed by HNers who have had to build this functionality. If there are references, please share.

We did. By a lot. A few months ago we implemented a new hibernation mode that suspends location services more aggressively when you're not active. This saves about 50-90% battery on an average day. The only downside of this approach is that we can't show the first 100-200m on a map when you start moving again. If you find that important, you could use the high accuracy option at the expense of a bit more battery impact. Try it!

Uber like Airbnb is leveraging individuals capital (or ability of drivers to go into debt). However unlike ground in prime location they are literally stamping out new cars every minute. In case of self driving cars it is Uber putting up the capital and margins in transportation fleet business are smaller than what the current Uber valuation implies. Differentiation will be difficult.

It is a risky strategy for Uber but it is hard to see an alternative for them.
> ebook in a niche technical topic

It won't get you much passive income, if the topic is very niche. If it is more popular, there's bigger competition, so you have to be lucky.

I wrote a technical book (ebook + paperback) in veeery niche technical topic (and it's the only book on this topic on the market), got one-time moderate paycheck from the publisher and that was it. If the book gets me any passive income it will be just a few buck a month, not earlier than in 2-3 years (when the book will be obsolete anyway...)

What I earned was invaluable experience and some insight into how I work and how I can improve it, but that's it.

Do you not think that French rail has generated at least 50 billion for the economy? After Japan, France is the highest user of rail (km per person per year).

It's fine for public transportation to not make back the investment if the advantages to the public are high enough (though with the Franc that's easier to deal with than the Euro)

"passive income" means regular income that does not require your activity. Common examples are bank interest, stock dividends, real estate rent, copyright or patent royalities.

In the big picture, some activity is eventually required, it's just a matter of time - books fall from favour, patents are superceded, even banks can go, well, bankrupt. So it's a question of degree, and of how much return.

Of your suggestions, SaaS requires a lot of ongoing work. Most books and games have hit or fad-like popularity - so a low chance of on-going income after you are done.

Your "niche" idea is the best of the three - but it's completely dependent on finding a niche that is under-served, and will continue to be under-serves. That way, the income can continue for as long as the technical niche exists (it eventually will be superceded, and perhaps the surrounding ecosystem also swept away). The downside is you generally can't make much money this way - but you didn't ask for that, so it's fine. Remember the saying "you won't get rich writing books".

So the tricky bit is choosing the niche with these market characteristics AND that is personally easy/interesting/attractive to you and not to others.

BTW: I wrote a couple of chapters for a book, got a decent advance on royalties, and IIRC about $4 royalities after that (most books don't "eat out their advance"). This was on a technical topic, but not really niche.

A word on passive income: I succeeded in this with a software product... but discovered that my life became about invoices, negotiating license terms and international taxation law. I was so much happier actively developing!

Since you'll end up doing something, I now think active income has a lot going for it! [Of course, you're only requesting some passive income, so this may not occur.]
what if the nature of the physical universe has no other reason to be as it is other than mathematical consequences of harmonies, resonances, balances, etc? In other words: if all that exists follows mathematical law, doesnt that make math part of the existential?

Great question.

Even a human brain has to train for ~4-5 months to become interested in shapes (https://en.wikipedia.org/wiki/Infant_visual_development). Once the human brain has been trained for these basic shapes for a while, it is able to quickly break down a new class (i.e. a cat) and recognize similar patterns in other images. This is something that is very similar to the way that training a deep NN works.

Also don't forget that the current NN are being trained mainly for photos, not moving images. A brain may recognize a cat by its tail-wagging or fur movements, which is a dimension that is completely missing from still images.

I was thinking launch silos when I wrote it, but it's a deeper question now that I think of it.

Could a conventional attack on a power plant and the fallout from it be considered a nuclear attack? What about a nuclear powered air craft carrier?

Is an attack on a nuclear armed submarine, would they be considered an attack on their nuclear capabilities? The attacker might not even know what type of submarine it is.

That's because of the high speed passenger rail which even got extra infrastructure in France.

In Germany the public railway company Deutsche Bahn makes more than 1 billion in profits. All the profits come from freight, transporting people is done at a loss. The problem is that not enough money gets invested into upgrading lines highly frequented by freight.
28 Tools to Help You Launch Your Startup
One disambiguation: everything involves the presence of quantum mechanics, insofar as Newtonian physics isn't how the universe actually works. It's not entirely obvious where to draw the line here in calling an effect "quantum" or "not quantum"; Newtonian physics alone doesn't explain the majority of chemistry or electricity, for instance, and the body wouldn't function without a wide variety of chemical and electrical reactions. The brain (and absolutely everything else) runs on the actual physics of the universe, not on a model we might have of it.

The default assumption would be our current model of how the brain works; any model proposing effects (quantum or otherwise) not yet accounted for would require an appropriate amount of additional proof. When I suggested which seemed more likely, I was taking priors into account.

More generally, though, I wasn't referring to concrete models that make specific claims about how the brain works; I was referring to the rather frequently stated vague claims that use "quantum" in a way that would have no more or less meaning with the word "magic" substituted. A specific concrete model would be amenable to prediction and experiment.

Whether any particular such concrete model seems probable or not would depend on what it claims. For instance, a claim that the brain depends on macroscopic quantum effects at a far larger scale than observed elsewhere seems improbable; a claim that the brain depends on properties of chemical or electrical interactions that quantum mechanics explains better than other physics models seems relatively less improbable by comparison, depending on the details. Whether any particular claims seem probable or improbable would depend on our current understandings of quantum mechanics, the brain, evolutionary search processes, and so on.
Imho, that is not a good metaphor, because all streets are basically the same, whereas software is always very different (and way more complicated).
Static Code Analyzer Reportedly Finds 10,000 Open Source Bugs
I have a 4 iOS apps on the App Store, however only one of them makes significant income, approx. $500 a month. It's a road traffic app for the UK which I originally built to satisfy my own need - I searched the App Store and all the apps I could find were either very clunky to use and not very reliable.

So if you can find a niche, and improve the UI/UX on existing apps, then there is definitely scope to make some "passive" income on the App Store. I put passive in quotes as anything you do will require upfront time and effort and also some ongoing support/updates.

In my case I spent a few months (evenings/weekends) building the app and now spend a few hours each month either responding to support emails or fixing bugs/releasing small updates.

Don't underestimate time for sales and marketing; whatever you decide to do will require some form of promotion/marketing and getting the message out there that you have built something. I regularly update a Twitter account for the app as well as maintain a website showcasing the product.

Good luck in whatever you do.

Only some billions of years of evolution and a lifetime of knowledge abut how our world looks like! When you see a picture of a cat your brain has a whole lot of context to put the picture into: it looks like some live creature, has eyes, legs, you can tell where it's head is, you can imagine how the fur feels like etc.

An untrained neural net has to learn everything from scratch (ha!), from pixel values to "knowing" what a cat is. There is some work on decreasing the amount of data needed to learn, but it's a very tricky subject.
