This isn’t an application on a Mac, but it is a demo website for a series of qr-code libraries so it will work on any platform. It isn’t as convenient for people unfamiliar with QR codes, but if you need full control over the encoded data then this works really well.

The website does the generation in JavaScript so you don’t need worry about hammering some guy’s API if you needed to generate a lot of QR codes.

My problem with what you said is that it isn’t just capitalists that use patents and copyrights. Russia and China have patents and copyrights. It isn’t limited to capitalists, and saying so confuses people on what the actual issues are.

This isn’t really correct. Free Open Source Software is very much owned. It is just that the owner doesn’t charge for it, has stated that there are rules for use and modification of the software. FOSS was a clever trick that used copyright against itself. It is was a really brilliant trick, but that trick was only necessary because copyrights exist in the first place. If copyrights didn’t exist then it wouldn’t be illegal to redistribute Adobe Photoshop.

You may argue that copyrights are necessary for the betterment of society, but that is debatable. The biggest case against copyright being necessary is, in fact, the FOSS movement. It proves we don’t actually need companies like Adobe to make all our stuff and charge a lot for it.

The idea of free software isn’t political; ie socialist/communist. Free software is also compatible with free market capitalism. In a capitalist market free of coercion there is nothing that stops one from copying something then changing and/or selling it.

If you make a microwave and I buy one and reverse engineer it then I could produce and sell it just fine. Similarly, if you created a program called Adobe Photoshop, and I got a hold of the code, then I could copy and resell it. Neither capitalism nor the free market has a concept of patents or copyrights which are a political thing. Everything is free to reproduce.

Making the software free is just the logical economic price of a product with a marginal cost very close to zero. Give it away and let everyone build on top of it to make increasingly better things because that is the most efficient way to manage those resources. It’s like the progression of science. We give credit for discovery, but encourage all science to happen in the open so others can take the ideas and build on them without being encumbered.

I hope you don’t think that science is socialist/communist.

Note: After going through the trouble of writing this I became concerned that my use of the loaded term “free market capitalism” could be misunderstood so I’ve decided to define my terms. Free market capitalism isn’t a form of government. Capitalism just means stuff can be privately owned. A market is how capital is coordinated. The free refers to the market transactions being voluntary/free of coercion. So free market capitalism is the “voluntary coordination of private capital”. That definition can exist under varying forms of government which is why I argue that it isn’t a political system in itself.

Whenever my friends or I point to the sky after sitting in a chair in a McDonald’s on the second Saturday of the month while wearing a purple shirt. We just start cracking up until the manager comes out and tells us to leave.

You can do that, but there are a couple of things to keep in mind.

Different apps may only be compatible with certain database products and versions. I could be a real pain if you have to spin up a new version of a database and migrate just for one service that updated their dependencies or have to keep an old database version around for legacy software.

If you stop using a service then it’s data is still in the database. This will get bloated after a while. If the database is only for one service then wiping it out when you are done isn’t a big deal. However, if you use a shared database then you likely have to go in and remove schemas, tables, and users manually; praying you don’t mess something up for another service.

When each service has its own database moving it to another instance is as easy as copying all the files. If the database is shared then you need to make sure the database connection is exposed to all the systems that are trying to connect to it. If it’s all local then that’s pretty safe, but if you have services on different cloud providers then you have to be more careful to not expose your database to the world.

Single use databases don’t typically consume a lot of resources unless the service using it is massive. It typically is easier to allow each service to have its own database.
