QR-Code-generator VS lowdefy

The funny thing is that no-one AFAICT has realized that the same content can be encoded in different-looking QR codes. Beside the obvious (different error-correction levels), the content itself can be changed while maintaining its semantic meaning (e.g. "https://example.com/foo", "HTTPS://EXAMPLE.COM/foo", or "HtTpS://eXaMpLe.CoM/foo" are all semantically identical) and even the QR encoding itself can be tweaked (e.g. by changing the version and mask, see the demo on https://www.nayuki.io/page/qr-code-generator-library). Each combination would yield a different-looking QR code that would encode the same meaning, and it could therefore allow the diffusion models even greater freedom.

I'm sure somebody will get to this soon.

Make a hidden Veracrypt vault on cold computer. Inside the Veracrypt vault save Keepassxc vaults. Store your seeds inside the Keepassxc vaults. For a paper backup, encrypt your seeds using an offline AES256/512 text encryptor/decryptor. Encode the encrypted text using an offline qrcode generator. Print out the qrcode. Test recovery using a dummy wallet. Be sure you can scan and decrypt. Bonus: Laser etch the qrcodes on metal plates. Make a multi-factor recovery vault, in case you forget your passwords. Shimar's secret sharing scheme is a useful tool for making your recovery vault. Never store your seed unencrypted anywhere, ever. Never input your seed on an online computer, ever. Always protect your seeds with something you know (password), something you have (vaults and keyfiles). Do not upload your vault to the cloud. Keep backups in multiple locations. Necessary tools: Cold computer: Any old computer will do. Just physically disable network access.

I probably know this only because back in time I wrote a QR code generator in JavaScript [1] which was also one of such libraries reviewed by Nayuki [2], and as I haven't actually implemented a decoder my knowledge stops there. Sorry :-)

I guess it helps to understand how to generate a QR code: https://www.nayuki.io/page/qr-code-generator-library (see also the references at the end)

Good luck. ;-)

i think i found what i was looking for

I'm really enjoying reading through the docs and the tutorial. We've created Lowdefy, a config web-stack which makes it really simple to build quite advanced web apps. We're writing everything in YAML, but it has it's limitations, specifically when doing config type checking and IDE extensions that go beyond just YAML.

I've been looking for a way to have typed objects in the config to do config suggestions and type checking.. PKL looks like it can do this for us. And with the JSON output we might even be able to get there with minimal effort.

Is there anyone here with some PKL experience that would be willing to answer some technical questions re the use of PKL for more advanced, nested config?

Awsome! With Lowdefy we tried to build a low-code framework that works like code. We’ve developed a schema in which to define applications and we’ve built all kinds of apps for enterprise customers. Massive, advanced CRM systems, call centre solutions, ticketing systems, a light MRP, all kinds of survey apps and so many dashboards. Even our docs and our website are Lowdefy apps!

Give Lowdefy a try and reach out it you have any questions or want to see what is possible :) (We need to invest a lot more into content and examples, bootstapping is a grind!)

100% this. And yes, good documentation takes a lot of investment but it pays off like compound interest. But with that done, it becomes even more important not to pull the carpet for no good reason, you are building a tower and documentation is at the foundation.

We’ve built Lowdefy [1] as an open source project and documented it with all effort, 200 pages of docs. I often forget why or how something works and then jump to the docs. This investment keeps on paying of as we use Lowdefy to build customer apps, new devs in the team typically take less than two week to get up to speed and start making contributions, the sharp ones, just a two or three days.

This year, we’re extended our documentation onto customer apps aswell, with flow diagrams, state machine definitions, detailed field level explication schema definitions, and end user test procedures. The key here for this documentation is detail. It should be easier to reach for the docs and the the answer, than to dive in the code and interpret it.

Check out https://lowdefy.com/ they even have a sample survey app as one of their examples.

You can build an app that would do this

Lowdefy is a low code tool that uses AG Grid as a block component, allowing you to create apps which render data in AG Grid without a lot of coding knowledge. There is a Lowdefy example using AG Grid here.

Shameless plug, also check out Lowdefy - https://github.com/lowdefy/lowdefy

I’m also going to jump in here and say try Lowdefy https://github.com/lowdefy/lowdefy - co-founder here.

We take a different angle and believe that low code should still work like code. We focus on a developer first approach.
