One way is to write ebooks and sell them on Amazon. If you write things that don't get dated, there is no further work on your part, Amazon just deposits money in your account.

It's highly unlikely you'd make $1000/mo on a single ebook, but if you write several, the trickle from each adds up.

Think of the value as a user preference along the lines of "Do you want to see the product tour? [Yes|No]". How would you store any similar user-set preference?

In Usable Requirements (http://www.usablehq.com) we use an untracked JSON object as part of the user document for preferences (this is in MongoDB). This means we don't have to keep a schema up to date - the front end can essentially put anything in that object (subject to some validation obviously). Consequently the front end code has to be tremendously defensive as values may or may not be there, but that's a good thing anyway.

I hate to be the cynic (lies), but there's no such thing as a "passive income". The moment you put your service online you'll have active maintenance and support, even if you don't charge for it.

The other problem is that if you solve a problem well, it's actually extremely hard to avoid the business scaling. Once the revenue goes past 1k/month, it'll carry on going, and few people can bring themselves to remove purchase links.

I know that's essentially what you're asking, but my answer would be no, it's unlikely that you can find a model that fits exactly the criteria you have.

I notice many people posting ideas, rather than low-maintenance ideas.
totally agree with this. learning how to market is underrated big time. i'm taking this route now by writing first, building an audience and then see how i can launch things later on
You'll have maintenance and support especially if you don't charge for that.
"Were charges filed" is not a productive criteria for whether or not a search was reasonable.

In this case, it should be! Keep in mind the kind of evidence they were working with.

And nobody's talking about traffic stops, but call me crazy when I say I think terrorism should entail a slightly higher standard than that.
If you like Kotlin also look at Ceylon from RedHat. In some ways very similar to Kotlin with null-safety and improved generics.

In the Appleverse, we call it Option, not Alt.

(I know the key says "alt" too, but it's smaller type for a reason.)
I guess so. But for those who want to avoid paying it, buying things daily is less risky than going through the bank. Just like with earnings in cash that you spend in brick and mortar stores.
Interesting use of "physically".
MySQL's query optimizer is a joke compared to Oracle's. If you don't do joins and just use it as a key-value store, that doesn't matter. MySQL also doesn't enforce most SQL constraints like "can't store a string in an int field" etc.
even better - possibly a Chrome app that comes up when you open a new page. Similar to the Currently Chrome app.
Two ideas.

1. I desperately want to be able to send a link to somebody and have them be able to book a N-minute meeting on my calendar (CalDav) without any further interaction. I have spent probably several hours trying out products, all of which suck. I currently spend $30/month on a tool that really doesn't even work.

2. The enterprise IM (CampFire, HipChat, etc.) is pretty well done at this point, but the "group chat for the somewhat public" space isn't. If I am supporting an open-source project the only game in town is IRC, which is hard to use for people who need support. If I want to have a permanent chatroom with 15 software developers that I know socially and allow people to drop in, there's no system for that.
Who is "we" in this case? HN? The US? The UN? Humanity? If we don't get to choose for ourselves (for any definition of "ourselves"), who's making the choice for us, and why are hot war and cyber war the only choices?
I use one of these for various side tasks, because I got sick of having to run cron jobs for servers that I might switch between or kill off, and I run a lot of cron jobs. I also like the idea of offloading the cron hits to an independent service, so my servers focus strictly on more important tasks.

http://cronless.com

It's the first one I found that I liked and was reliable. It's very modestly priced as well.

I wouldn't suggest this for passive income however, as cron is a very low cost, value added type product. It's difficult to charge much for it stand-alone. You'd want to bundle a suite of services, like ping / uptime, cron, etc etc. into one.
talking about mobile space, i believe OpenGLES is used in embedded platforms instead of OpenGL, which is a stripped down version.
> Reliability is key, your service needs to never ever fail.

Then that sounds like it need a serious full time commitment. The OP seems to be looking for a specific category of ideas that require minimal maintenance, rather than any ideas.

Contrasting with AMD, the AMD drivers are a complete mess. I have a card that was released about a year ago (HD7800) and I can't dual-screen on it with the AMD drivers (maximum total resolution is 1920x1920 - yes, that's not a typo). Regardless of effort, the graphics drivers AMD produce are terrible, and the free version doesn't deal well in the gap (pitcairn chipset). I would not be pointing at AMD as a role model in this regard.
I missed your show HN thread, sorry. But for what it's worth I think your service looks cool. Your pricing looks too low to me - perhaps a sign of your lack of confidence in the idea - I think you could do with some higher-volume packages too.
I'm thinking more in terms of consumer networks. I really don't want my ISP to know exactly which devices I'm using or how many, nor do I want to have every web site be able to track them by globally routable IPv6 address everywhere I go. Simply blocking incoming connections doesn't solve that.

Taking credit for someone else's work is not a useful analogy for NAT, nor are the corresponding moral implications relevant.
That really depends on the overall situation. Financing a car that you could afford in cash might well be less risky than having too little cash on hand for emergencies.
Is this even legal? they released the previous documentation under GPL v2 which has a clause stating any modified versions have to be released under the same license. This new documentation is clearly just a modification of the previous documentation. It would be interesting if it came of they did not have the right to do this. If even even one line of the documentation was written by someone else and they did not get a transfer of copyright they could get sued for doing this.
It's substantially cheaper (30%), if indeed it does the same thing and works as well.
I believe HipChat has this concept of 'Guest Access'. Won't that be helpful, just curious.
Style vs. Substance in Mobile Software
Is Rolls-Royce like Boeing?

This is a fun game.
Only because it's easier to support OpenGL ES. If a GPU is available that supports full OpenGL, that would give greater flexibility features to mobile developers.
My employer's legal department loves BSD and MIT licenses because it's easier to sell software that way. When we need to update or add a new library or application, BSD/MIT licensed software get approved much more quickly. For example, we need to update the snmp package but we can't get it through legal because the license for many of the modules changed to GPLv3. A new python module would really make some things easier, but we can't get it through legal (GPL again).
Via Little Snitch, I noticed it contacts your radioformac.com webserver on port 80 on launch. I didn't sniff the traffic but presumably this is for a list of stations or something?

Could you please update to use SSL/TLS (https) instead? It's for the server authentication, not so much the transit security.
dustin curtis sucks balls
Lots of UI lag when typing the first character into the "all stations" filter/search field, and again when deleting the last character remaining.
I would suggest leaving your comfort zone.

Developers like myself have a tendency to reinvent the wheel, as in, solve problems like online team chat over and over again. Because that's what we know first hand and are comfortable with.

The webapp for online marketeers I'm currently building, with feedback from a friend in the industry, caters to a bit of a niche but I'll probably have far greater success with it because that niche is quite underserved. I would never had thought of that particular idea had I not wondered off outside my comfort zone and talked to people in other areas.

I don't expect my project to become a passive income stream. It'll take work. But maybe the same method can be applied to find a problem which has a trivial, low-maintenance solution.

I wasn't. I agree that the closed-source drivers AMD also still produce are friggin' terrible, and far worse than nVidia's closed-source drivers. AMD has been much better about supporting efforts to write free drivers than nVidia has, however. In terms of serving as role model I'd say Intel takes the lead by actually developing their sole drivers out in the open _and_ releasing hardware documentation so others outside the company can help out. Even Intel as had their missteps however (e.g. the infamous Poulsbo driver mess).
This isn't a good strategy. First of all the timing factor alone can hammer your principle (particularly with stocks sitting at all time highs).

If you have a skill that is valuable, you're far better off leveraging into that, for the returns are massive by comparison to the puny returns in stock indices. If you can earn just 10% every year in stocks, you're a wizard that should be working on Wall Street earning millions.

It's radically easier to invest $100 into hosting ($10 or $20 / month at digital ocean), build a service, and make $1,000 a month (a huge return on the invested capital) - than to earn a mere 10% per year in stocks.

$1,000 / month = $12,000 per year. To put together $12k per year from stocks, at a 10% return (which is a great return per year historically), you'd need $120,000 in capital to begin with.

Scenario 1) you need $120k in cash to put to work in stocks to yield just $1,000 per month average in new capital, assuming a great historical return (and assuming you don't get demolished by a market down turn). And if you're riding dividends, you're going to be hard pressed to consistently yield 10% every year even from the best dividend investments (such as public trusts, real estate vehicles etc).

Scenario 2) invest $20 per month into a hosting account at digital ocean and build a service that yields $1k per month in income.

#1 is silly compared to #2
Some more examples: the LGPL is copyleft and you can convert it to the GPL. Sometimes the GPL comes with a special exception, which can also be removed. AGPLv3 is more restrictive than GPLv3, and again you can convert GPLv3 to AGPLv3.

If you consider what developers are allowed to do with a piece of software, the main element of copyleft is actually not being able to relicense under a less restrictive license on the spectrum of FOSS licenses. The least restrictive "license" of all is no license, no copyright, i.e. public domain (in the US).

Because you can convert MIT/BSD to a closed source license, but you cannot convert GPL to a closed source license, in this sense the GPL is more restrictive than MIT/BSD. You can convert MIT/BSD to GPL (less to more) but not GPL to MIT/BSD (more to less).

I understand that closed source licenses are the most restrictive of all, this is just an alternative perspective on software freedom with regard to developers.
The parent was asking a rhetorical question, and drawing an analogy between the two: omega and ohm have different meanings, therefore it might be useful to be able to distinguish between the two. (Note that I say 'might'; when it comes to a character set, I'm not sure I 100% agree ...)

Yes, that's what everyone has been using so far, and that's what everyone will keep using for at least several more years (they've just started adopting OpenGL ES 3.0, so they won't change soon).

However, Nvidia is actually going to use the full OpenGL 4.3 in the next Tegra, next year, since it's using the full (but probably more optimized) Kepler PC architecture, so it has support for OpenGL 4.3. Nvidia is going from OpenGL ES 2.0 straight to OpenGL 4.3. For comparison, not even Intel's Haswell has OpenGL 4.3 support (still stuck at 4.0 only). Tegra 5 will also support CUDA 5.0.

No lots of jobs, no, but there are jobs. It's an interdisciplinary field, so your math and programming background will hold you in good stead. Some basic stats are a good idea too.

Of course some people are doing OR but don't know they're doing it. Some just use another label. Other useful search terms include "management science", "operational research" (UK), "advanced analytics", and of course "optimi(s||z)ation".

2. Like iffyuva said, I believe HipChat has that option. As does Campfire. The thing is maybe those groups aren't willing to pay for such a solution?

Sun didn't become Oracle, Oracle purchased Sun, so it wasn't Oracle who paid Monty. When Monty sold MySQL to Sun he believed them to be a good fit for the project, and they would keep it going in the spirit he hoped for. He could never have foreseen it would be sold to Oracle.

And yes, it has always been dual-licensed, but as Monty himself says: "The basic idea for our dual-licensing was this: if you bought a license then we waived the GPL restriction that you have to redistribute your code as GPL. You could change, modify, extend, distribute, and redistribute the copy in any way you wanted (but of course not change the license of the MySQL code). The license was for any version and usage of MySQL, for now and forever." [1]

Not many would use full OpenGL, which is optimized for CAD developers. The ES subset actually represents modern programming practices, with only a few extensions missing for the more recent features of the pipeline (hull shaders and such).

This could be nice for small apps. The problem with higher-scale apps is you want to handle requests as quick as possible - they should be well under a second. And under typical server configurations, it will time out altogether after maybe 30-60 seconds.
Actually Kotlin has null safety as well[1]. Not sure how generics in Kotlin compare to Ceylon, but it also improved on Java's generic support[2] by eliminating wildcards, type projection, inferred types and some other features.

Random question, but how far along is Ceylon's development compared to Kotlin's? I know they're both relatively new still, but just wondering how feature complete it is so far.

MongoDB vs MySQL
I don't think you were all wrong - there's a difference between username and name. My name has a space in it, but they won't allow me to represent that in the username. And if my name is already used by someone else as their username, I can't use it as mine. This doesn't bother me, so long as my name is displayed properly in the UI (if at all).
So now, projects that need parallel crypto-cracking can use GPGPUs instead of FPGAs. This works with any other strategic GPGPU application as well. The military no longer needs to buy a bunch of Sony gear just for the CPU. Defense contractors or grant-funded university research departments can design and use a GPGPU solution and have more control and customization than using off the shelf parts.
Uhh, it's called a tech startup. Just because most of them fail doesn't mean it's asking the impossible. This very site exists because even a tiny positive hitrate is sufficient for significant positive return.

Everything from AdWords to Uber is just "people replicating the idea" into $1M+/month.
OpenStreetMap is awesome but not really a map service, it hosts the open data and the map editor/wiki. You can use their map to a certain extend but if there was a huge spike in traffic, their site would fall. If you want a good service based on OSM with directions and more, you have to use something else such as mapquest which is US based or host it yourself.
Partial Tesla Model S recall
This can be true, but Facebook is also used as a tool for people to measure how good they are doing in life to one another. Last weekend a friend of mine started talking about how ugly a specific kid was, then went on Facebook to look up a picture of the ugly ginger kid. Then when scrolling through 'the wall' he went on and on and gave his shallow judgement about people who all were doing worse than him in some way. Probably to reassure to himself that his kid is better on the scale he invented and that his life wasn't that bad after all. Sadly it's not the first conversation like this I overheard. It is one of the reasons I left Facebook, maybe private life should remain what it is, private.

His quote about society is absolutely beautiful.

"It would be like suddenly subtracting the strong nuclear force from the universe; the fabric of society would instantly evaporate, every marriage, friendship and business partnership dissolved. Civilization, which is held together by a fragile web of tactful phrasing, polite omissions and white lies, would collapse in an apocalypse of bitter recriminations and weeping, breakups and fistfights, divorces and bankruptcies, scandals and resignations, blood feuds, litigation, wholesale slaughter in the streets and lingering ill will."
That's not 'hot war', that's all 'gunboat diplomacy'. If it is a war, it's still a cold war. Militarising coastal waters to apply pressure. If the US was in a 'hot war' with Iran, there would have been more than a planeload of civilians as casualties - a 'hot war' is one were there's been a declaration of war and there's an armed conflict going on.

People died all the time on the interface between the First and Second Worlds, yet it was still termed a 'cold war' for the decades it existed.
No worries, a lot comes in on HN. Thank you, you have no idea how much that means to me!

Too low? That's a great sign too! In regards to higher-volume packages, I most certainly agree, however we want to ensure we're able to handle the potential volume of requests so far.

What do you think about the limits and throttles for each package?

That's quite a sweeping (and inaccurate) generalization.

I have no experience banking in Vietnam but what he said certainly applies to both China and Thailand, if you stick to the largest banks (ICBC and Construction Bank in China are both probably safer than any US bank - Bangkok Bank, Bank of Ayudhya (owned by GE) and Siam Commercial are all rock solid in Thailand - along with HSBC in both countries). Singapore and Hong Kong are both also extremely safe places to bank and very foreigner friendly.

Source: Lived over there for 6+ years. Still bank with all of those banks, more or less doing exactly what he suggested. In China I earn 3.5% on my RMB term deposits + appreciation vs the dollar, which is almost as predictable as the interest. Personally, I prefer that to 0.1% at Wells Fargo.

I launched a forum in 2006 and it so far generated passive income nicely. However since 2011 the revenue continuously declined. Building a forum is great due to user generated content.

Other idea I had was to build a reddit scraper. The site has like 500 users a day. I take the content and make it more readable and fun to use.

I really like the concept of scraping, taking content and enhancing it.

My GSOC project for this year is an extension to for comprehensions to enable LINQ-like conciseness without LINQ's inflexibility. If it ends up being merged into the compiler proper (a pretty big if), it should really help to make writing complex queries a lot less painful.
