Ask HN: How do you make a profitable business out of an open-source project?
I've recently published a note-taking app [1], which I open-sourced right way, and it amazingly got a lot of interest from the community.

I'd like to make the best possible note-taking experience out of it, that implies developing a web-app, mobile-apps and generally putting considerable resources into the project.

I think the best way to ensure all this will come to fruition is if the app/service itself was profitable, ideally I would like for it to pay for itself and also provide enough funding for future projects of mine.

I'd like the business to be defensible, but also avoid making the app closed-source. I'm not sure how I could avoid having the (probably simple) server reverse-engineered at some point in the future in order to avoid paying for an eventual subscription fee though.

What do you think is the best way to achieve profitability?

If you're working with thin steel sheet, or some aluminums, building your own sheet break is pretty easy to do, even without access to a machine shop.

It's a much cleaner finish than the hammer+vice combo.
A device would only need a camera to receive information, and yes, at the point you need bidirectional transfer, I'd concede that this isn't the best method.

However, adding a small lcd display allows the presentation of human readable data as well, and many devices already have screens on them.

(I always thought serial over TRS (headphone) cable would be an interesting option as well.)
I live in Seattle, east of here there is one BMW dealer on my way home and next closest BMW dealer is in Boise, Idaho. I can’t drive to my home town and visit a dealership. That means an electric BMW would need a range of 1,000-1,200 miles to be remotely comparable to an ICE car or Tesla.

Putting universal chargers at existing gas stations or buying an entire brand and converting to charging makes way more sense.
The way to make money "easy" is to have a skill combined with an insight that most other people don't have, and work to exploit that ability for profit. For example, someone who is a good application developer but works in a dental office can identify what exactly is needed by that demographic, and how much they are willing to pay for it (thereby using their potentially "hobby" skill of programming to create that run-away successful SAAS startup).

But once you hear of other people doing something (drop-shipping items from China to Amazon, or cryptocurrency mining), chances are very good that you will have too much competition. The only way to make it big is if you get into that business before you hear of it off the street.
You don't go charge a car to a dealership though. I charged mine yesterday in the parking structure next to the mall in Colma while getting ice cream with my son. Sorry but no, that's not a valid suggestion.

Native PGP is something I'd be very happy to see. Enigmail is needlessly complex with long setup wizards that frequently fail and a lot of legacy code supported for old distros. Services such as ProtonMail show that focusing on modern conventions and picking the right defaults can really bring encryption to normal users.

> At the end of the day, is he making the world a better place?

With rare exception, I don't subscribe to the idea of "key men" in general, and especially not in this case. Even if I did, I don't think that Musk is acting in a way that makes him an asset.

I agree that Tesla, for instance, is doing good and important work. However, I think attributing Tesla's success, and net impact on the world to Musk alone is unsupported by evidence. That's because aside from initial investment/PR, and sufficient cult of personality to inspire people to work for him at the start, I don't see what Elon Musk is contributing to the company's work at this point. In fact, I see him as a liability and I think Tesla would be better off without him.

Candidly, I also believe that if Musk was less driven by his own ego, as he appears to be, he'd see that and step aside.

This should be a standard and could be the Kermit of H2M and M2M systems.

It would be interesting to try bidirectional transfer using the front facing cameras with two phones pointed at each other.
It is up to your implementation if you consider JWTs without an exp field to be valid.

Our implementation requires a number of fields that are optional in the spec.
If buses arrived every five minutes and had a dedicated lane, people would not be stuck anywhere and people would certainly want to use it. Here is a thought. Walk to your nearest busy street. Assume you could convert half the number of cars to buses and that a bus would have about 20 riders. When you count 40 cars go by, that is how often the bus would arrive.
At least from what I've read, the primary problem have been a lack of financing for maintaining the current system. The subway does need to move to a more advanced signaling system, but there's no reason why the old-fashioned signaling system has to be falling apart.
The same BS peddled by people like Gary V and co.
We must be living on a different planet then if you never heard a Tesla owner go on and on about how much they love their cars. Before buying one 4 days ago I had plenty of that kind of experience.
Ultimately, the 68k upgrade path was not THAT long. But I agree with the rest of your argument. As the triumph of x86 has shown, in microprocessors, superior shipping volume can drive investment that covers a multitude of architectural sins. And the 68K architecture was quite nice, actually.

Absolutely, agree 100%. A major problem is that economic growth has been spent on, say, propping up ski resorts in upstate new york, instead of reinvested in the subway. It's really an absolute travesty the way the system has been managed.

> I don't know what he's done to earn my trust, or any investor's.

The ~20x ROI since IPO has made many people trust him. Tesla itself is a marvelous success, with no established car maker able to match them yet. It is far more likely that your personal dislike of him is making you see a distorted reality.

The price customers pay has increased but the amount of money that Tesla gets for each car has decreased.

That reduces Tesla's revenue for each car so it is a price cut from the point of view of the company and its shareholders.

> My issue here is that expiring JWTs involve adding state!

I don't agree. The expiration timestamp is not a state, nor is a nonce/token id. Moreover the specs enable servers to arbitrarily reject tokens, which means servers can arbitrarily request token refreshes. This means that any argument regarding how a nonce is a state is entirely irrelevant and without any practical interest.

Devops and security project work

We are a team of two, focusing on security, automation, CI/CD, cloud infrastructure design and implementation (primarily AWS with Terraform). After about a decade at Google/YouTube I realized that most startups just wing it and could benefit greatly from a short stint with an SRE to get them going in the right direction in terms of: security, automation, CI/CD, and intentional systems design.

Most startups don’t have time to prioritize security, automation and operations best practices, even though these things pay off in the long run. That’s where we come in.
For example, we created a Terraform template for secure, scalable initial infrastructure on AWS. (You can stand up your AWS infrastructure in minutes). We’re happy to give that away to anyone who asks because that gets everyone started in the right direction.

I founded my consultancy with the goal of helping everyone do DevOps just a little bit better. I am working with one other person who I have trained in best practices. We’ve been operating for two years and have completed quite a few successful engagements.

>is that some classes of valuable mental performance are very hard to generate metrics for or even define at all, and therefore, you would expect them to correlate with IQ less or not at all.

I think the crux of Taleb's point is that the kind of mental performance IQ is a useful metric for is not valuable (including the associated jobs and roles that go with it).
I'm not sure about that particular design but there was the 65816.

>If history has taught us anything, it's that technological progress is orders of magnitude slower than people expect. The infrastructure of NYC, LA, Seattle, San Francisco, etc will not look much different in 2059 than it does today.

I think there is a Bill Gates quote about how most people overestimate how much things will change in one year and underestimate how much they will change in ten.

Of course, when you find yourself 10 years in the future you'll probably just forget how different your city used to be because the changes unfolded too slowly for you to notice they were changing. In most of these cities, for example, the infrastructure might look the same but the way people are using it is very very different.
Perhaps the coke/stripper parties and Insider Trading on Wall ST would have been a better approach. I'm sure the SEC would have found that more appropriate and acceptable.

Certainly possible. I personally think he's acting like a buffoon and I haven't been shy about stating it.

However, as I told another commenter in this thread, I think the relatively objective argument is that while Musk was necessary initially to get Tesla into existence and functioning, he's now more of a liability than an asset. It's not that he was never valuable or never deserved any trust - rather that he doesn't deserve it now.

Put another way: At what point does the goodwill he's earned expire?

They're closing a few downtown stops that saw low usage to speed things up, but it will still be sluggish. I think the only real solution would be to move the Red/Blue lines to the transit mall and put all the downtown track underground with a cut-and-cover tunnel.

And this is despite all the options of electric cars on the market failing to live up to the average Norwegian's criteria.

Many Norwegians are still waiting for a "real" electric car to become available. Where a real car is defined by:

- Tesla range

- 450 liter+ luggage room

- Roof rack/box

- Tow bar

In particular with Tesla you get EITHER the tow bar (model X) OR the roof box (Model S). So even IF you splurge on a luxury priced car, it feels like compromising vs getting a gasoline car.

(Also Tesla is "very large", it does not fit comfortably in parking spaces; 180 cm wide cars are really a lot more convenient than 200 cm around here).

The moment anyone is ready to just deliver something like an electric Volkswagen Passat station wagon they will sell as many as they want in Norway. But, every single announcement fails to meet these criteria. It is a standard that lots and lots of gasoline cars fullfill, but currently no EVs. (Audi e-Tron is first, but still has a too large footprint, and also too expensive for most).
There are definitely other factors at play, but have no illusions about it: if the United States didn't mind killing and maiming a large number of innocent civilians, it could just knock down entire cities and wipe out entire populations if it wanted to. The main reason that those conflicts are tough is because the US tries to make a show that they care about human rights instead of just shelling the crap out of insurgents.

And the current struggles of the American military only result in hundreds or maybe thousands of American deaths, which historically, would be a mere rounding error. Afghanistan, Iraq, Syria, et. al. are a mess, but they don't come to a significant human cost to America.

The United States and its voting populace doesn't really care about whether or not developing countries are wartorn, and quality of life is decimated—America and other states have completely destroyed the backbone of several societies in the Middle East and caused the deaths and relocation of hundreds of thousands of innocents, but you don't feel the pain of that when you live states-side. So the country has little incentive to quickly resolve these conflicts besides the bad PR; ongoing conflicts mostly buy time for protracted, proxy diplomacy with other major powers to lay claim to natural resources, and aren't viewed as conflict with a tangible human cost.
> When someone's account is compromised, is another situation.

Why is that scenario relevant if tokens are supposed to be used once per request and short-lived?

Once a token is used, it's supposed to be expired and no longer in use. Both the expiry timestamp and the nonce fields already handle those use cases.

Which is why I prefer carbon/gas taxes.

If you’re a very light driver (eg: a short commute to work and back. Some people make 2 trips a week: church and grocery store), your carbon footprint from buying a Tesla is probably higher than comparable ICE cars.
this works at 3-4C, falling down the efficiency drops off rapidly.

House geothermic heating is very similar, except the collector is buried under the ground where the temperature doesn't really go negative C (until -30C and depends on the soil, etc). Overall for EV cars in cold winters producing heat is a non-trivial task.
